Description

Information sharing method and device and terminal equipment

Technical Field

The embodiment of the application relates to the technical field of terminals, in particular to an information sharing method, an information sharing device and terminal equipment.

Background

In a wireless communication system, a cellular radio networking mode is generally used to connect a terminal device with an access network device. Based on cellular radio networking, the signal coverage area of an access network device, e.g. a base station, is divided into individual cells, each of which may be assigned one or more center frequency points. The terminal device may reside within a cell and communicate with the base station over an air interface (air interface). The terminal device can reside on the access network device through network searching, the network searching process generally occurs when the terminal device is started to select the network, and when the user manually reselects the network, the terminal device is in a network-free (out of service, OOS) state or in a scene that the service quality of a service cell of the terminal device is poor.

In the network searching and network residing process of the terminal equipment, the terminal equipment needs to actively measure the information of surrounding cells, and decides how to reside on the basis of the measured information. After network searching and network residence, the terminal device can have more comprehensive perception on its service cell, for example, the terminal device can know public land mobile network (public land mobile network, PLMN) identity, physical cell identity (physical cell identifier, PCI), frequency point, reference signal received power (reference signal receiving power, RSRP), reference signal received quality (reference signal receiving quality, RSRQ) and the like.

However, the ability of the terminal device to perceive information is limited, and it takes a certain time for the terminal device to measure when searching for a network and camping on the network. Also, for neighboring cells or other cells around them, the terminal device can obtain relatively limited information, limited to RSRP and RSRQ. Therefore, the terminal device has weak ability to sense the network information of the neighboring cells, which also results in that the terminal device needs to perform comprehensive measurement on surrounding cells based on the configuration of the network to stay in the cell with better service experience when switching the cells, and the time is long. In summary, the method is limited by the information sensing capability of the terminal equipment, and the steps of network searching, network residing and cell switching of the terminal equipment take longer time, so that the user experience is affected.

First, a wireless communication system in which the embodiments of the present application can be applied will be described with reference to fig. 1. Fig. 1 is a schematic diagram of a wireless communication system in which embodiments of the present application may be applied.

As shown in fig. 1, the wireless communication system includes a terminal device 100, AN Access Network (AN) device 200 that provides a network for the terminal device 100, and a core network device 300. The wireless communication system may be an LTE wireless communication system, a 5G wireless communication system, or a new communication system in future wireless communication development. The terminal device 100 may be a device that provides a wireless communication service to a user, and in particular, the terminal device 100 may be a device that provides a service such as voice, data connection, and/or video image to a user. The terminal device 100 may be, for example, a user equipment UE, a device-to-device (D2D) terminal device, or the like. By way of example, terminal devices 100 include, but are not limited to, smartphones, tablet computers, personal computers, workstation devices, large screen devices (e.g., smart screens, smart televisions, etc.), wearable devices (e.g., smart bracelets, smart watches), palm game consoles, home game consoles, virtual reality devices, augmented reality devices, mixed reality devices, etc., vehicle-mounted smart terminals, etc.

The access network device 200 and the core network device 300 may be implemented in different network elements in different wireless communication systems. For example: in a 5G independent networking (SA) wireless communication system, the core network device 300 may be a 5G core network 5GC, and the access network device 200 may be a 5G access network NG-RAN (e.g., a gNB base station), or a NG-eNB base station upgraded from a 4G access network E-UTRAN (e.g., an eNB base station) to support access to the core network device 300. In a 5G non-independent Networking (NAS) wireless communication system, the core network device 300 may be a 4G core network EPC or a 5G core network 5GC, and the access network device 200 may be a ng-eNB base station. In the LTE wireless communication system, the core network device 300 may be a 4G core network EPC, and the access network device 200 may be an eNB base station.

In a wireless communication system, a cellular wireless networking system is generally used to connect a terminal device 100 and an access network device 200. Based on cellular radio networking, the signal coverage area of an access network device 200, e.g. a base station, is divided into individual cells, each of which may be allocated one or more frequencies (center frequency points), within which the terminal device 100 may reside and communicate over the air interface with the base station.

The terminal device 100 may reside on the access network device 200 through network searching, where the network searching process generally occurs when the terminal device 100 is turned on to select a network, and when a user manually reselects the terminal device 100, the terminal device 100 is in an OOS state or in a scene that service quality of a service cell of the terminal device 100 is poor, etc.

In an exemplary embodiment, in a wireless communication system such as 4G, 5G, etc., the process of power-on network selection registration of the terminal device 100 includes: powering on, initializing, selecting PLMN, scanning frequency, searching cell, solving system message, selecting cell, and residing cell. The step of selecting a PLMN includes PLMN searching, and PLMN information of the area where the terminal device 100 is located may be obtained after searching, and a PLMN list containing PLMN identifiers is generated, and the terminal device may select a PLMN for registration based on the PLMN list. The step of sweeping includes a frequency point sweep and a full band sweep based on the history. After the frequency sweep, the terminal device 100 may find a cell where it is camping properly and record frequency point information of the cell, etc. The step of cell search includes a process of finding the PCI from a suitable frequency point through a series of synchronization processes such as matching.

The terminal device 100 may also receive a reference signal, which is a periodic signal sent by a base station, where a cell-specific reference signal is valid for all terminal devices 100 within the cell. The reference signal may be used as a reference for the terminal device 100 when receiving data from the traffic channel, and the terminal device 100 may determine RSRP, RSRQ, etc. of the cell based on the reference signal. For example, when the terminal device 100 needs to be handed over to a cell with stronger signal strength, RSRP, RSRQ, and the like of the serving cell or neighbor cell may be determined based on the reference signal. In a wireless communication system such as 4G or 5G, the terminal device 100 may determine, based on a cell reference signal (cell reference signal, CRS) transmitted from a base station, RSRP, RSRQ, etc. of a cell, and further determine how to select the cell, cell handover, cell reselection, etc. based on the CRS signal. In addition, in the 5G wireless communication system, the terminal device 100 may use an SS/PBCH block (SSB) composed of a Synchronization Signal (SS) and a physical broadcast channel (PBSH) transmitted from the base station as a cell measurement target, and determine the RSRP, RSRQ, and the like of the cell based on the SSB.

It can be seen that, in the process of searching for network and camping on the network, the terminal device 100 needs to actively measure information of its surrounding cells, and decides how to camp on the network based on the measured information. After network searching and network residence, the terminal device 100 only has comprehensive perception on its serving cell, for example, the terminal device 100 can learn PLMN identification, PCI, frequency point, RSRP, RSRQ and the like, which is limited by the ability of the terminal device 100 to perceive information, and the terminal device 100 needs to take a certain time to measure when network searching and network residence. Also, for the neighboring cell or other cells around it, the terminal device 100 can acquire relatively limited information, limited to RSRP and RSRQ. Therefore, the terminal device 100 has a weak ability to sense the network information of the neighboring cells, which also results in that the terminal device 100 needs to perform comprehensive measurement on surrounding cells based on the configuration of the network to camp on the cell with better service experience when switching cells, which takes a long time. In summary, the steps of searching for network and switching cells of the terminal device 100 take a long time to influence the user experience, which is limited by the ability of the terminal device 100 to perceive information.

An application scenario of the embodiment of the present application is described below as an example.

Scene II: in a border roaming scenario, the terminal device 100 may remain camped on the roaming network, at which time the terminal device 100 may periodically search for networks to camp on the local public land mobile network (home public land mobile network, HPLMN) based on the network configuration.

Scene III: when the terminal device 100 is in the OOS scene, the periodic network searching is also performed, and after the terminal device searches the HPLMN, the terminal device resides, so that the service quality is ensured.

Scene four; while the terminal device 100 resides in a code division multiple access (code division multiple access, CDMA) network, the terminal device 100 may search for the LTE network by means of a system reselection (better system reselection) timer period to switch from the CDMA network to the LTE network.

Scene five: when the quality of experience (Quality of Experience, qoE) of the user of the cell in which the terminal device 100 is currently camping is poor, the terminal device 100 may measure its surrounding cells to switch to a cell with better QoE.

Scene six: when the terminal device 100 is camped on a global system for mobile communications global system for mobile communications, GSM) system or wideband code division multiple access (wide band code division multiple access, WCDMA) network, the terminal device 100 may make measurements of its surrounding cells to switch to an LTE network or an SA network.

The embodiments of the present application may also be applied to other scenarios for cell search and camping, which are not described herein.

In order to solve the technical problems, the embodiments of the present application provide an information sharing method, which can enable a terminal device to realize more comprehensive perception on surrounding environments by using information shared by other peripheral terminal devices, thereby reducing the time of searching and measuring of the terminal device, and enabling the terminal device to reside in a cell with better experience.

The following describes exemplary steps of the information sharing method provided in the embodiment of the present application.

Fig. 3 is a schematic diagram of information sharing of a terminal device provided in an embodiment of the present application, and fig. 4 is a flowchart of a first information sharing method provided in an embodiment of the present application, where, as shown in fig. 3 and fig. 4, the information sharing method provided in an embodiment of the present application includes the following steps S100 to S200:

s100: the first terminal equipment receives a first message broadcasted by at least one second terminal equipment, wherein the first message comprises network information of a service cell of the second terminal equipment, network information of a neighboring cell of the second terminal equipment and/or network information of a cell searched by the second terminal equipment.

Wherein the first terminal device and the second terminal device are terminal devices that can realize mobile communication and that can perform short-range (short-range) communication between terminals. The terminal equipment has more comprehensive perception to the service cell, has a certain perception capability to the neighbor cells of the service cell, and simultaneously has rich perception to the information of a plurality of surrounding cells when the terminal equipment searches the network again. The sharing of the respective known network information between the terminal devices may enable the terminal devices receiving the network information to also learn rich information, so that the terminal devices may save the procedure of cell measurement in the steps of selecting a cell or switching a cell, etc.

In this embodiment of the present application, the first terminal device and the second terminal device may communicate, specifically, the second terminal device may package and broadcast the known network information, and the first terminal device may receive the first message broadcast by the second terminal device, so that the first terminal device may search the network or switch the cell based on the first message, and so on. The first terminal equipment can obtain rich cell information without cell measurement.

It will be appreciated that there may be one or more second terminal devices in the vicinity of a first terminal device, which may receive first messages broadcast by its surrounding plurality of second terminal devices, or may receive first messages broadcast by a particular one of the second terminal devices, which may be, for example, the terminal device closest to the first terminal device. The second terminal device can share the first message in a broadcast manner, and does not take the specific first terminal device as an information receiver, so that as many first terminal devices as possible can receive the first message.

In this embodiment of the present application, the network information of the serving cell includes Public Land Mobile Network (PLMN) identification of the serving cell, physical Cell Identification (PCI), cell frequency point, radio Access Technology (RAT) information, reference Signal Received Power (RSRP), reference Signal Received Quality (RSRQ), signal to interference plus noise ratio (SINR) and service experience information, where the service experience information refers to evaluation information when the serving cell provides service support for the terminal device, and for the terminal device, the service experience information provided by the serving cell is better, which indicates that the serving cell is more suitable for residence. In practical application, the quality of service experience can be judged based on parameters such as TCP data packet delay or throughput rate of the terminal equipment. The network information of the neighboring cell includes at least RSRP and RSRQ of the neighboring cell. The adjacent cell refers to a cell which is in a switching relation with the service cell, and coverage areas of the adjacent cell and the service cell are overlapped. Since a cell may have multiple neighboring cells, in this embodiment of the present application, network information of multiple neighboring cells of a serving cell may be packaged in a first message and broadcast to a first terminal device.

The network information of the searched cell includes all PLMN information that the second terminal equipment can search. It will be appreciated that when PLMN selection is performed manually, the terminal device will form a PLMN list based on all PLMNs, and then the PLMN list includes PLMNs that are not available to the current terminal device. Then, even if the first terminal device and the second terminal device are registered on different PLMNs, the first terminal device can still find a suitable PLMN based on the first message shared by the second terminal device. If the second terminal device resides in a cell after network searching, the network information of the searched cell may further include PCI, cell frequency point, RAT information, RSRP, ESEQ, SINR and service experience information of a new serving cell of the second terminal device.

It should be noted that, after PLMN information is shared between terminals, the terminal device may select a PLMN based on the PLMN information shared between terminals, without performing a PLMN search step. The terminal device may also determine an appropriate frequency point based on frequency point information shared between terminals, and may determine a cell corresponding to the appropriate frequency point as a target cell where the terminal device is about to reside. The terminal device can also search the cell and find the PCI based on the proper frequency point, and then the terminal device can check whether the PCI searched by the terminal device is the PCI of the target cell based on the PCI shared among the terminals. Based on the RAT information, the terminal device can know whether a LET network, an SA network, or the like exists. Based on RSRP, RSRQ, SINR and the service experience information, the terminal device can know whether there is a cell around it that is more suitable for camping, so that the terminal device can perform network preference.

The first terminal device and the second terminal device may communicate based on a short-range (short-range) transmission protocol, for example, the communication manner of the first terminal device and the second terminal device may be bluetooth, wi-Fi, zigBee, or the like. Bluetooth, wi-Fi or ZigBee can control the communication distance between the first terminal equipment and the second terminal equipment, and the first message received by the first terminal equipment is broadcast by the second terminal equipment which is close to the first terminal equipment, so that the network information included in the first message is more suitable for the first terminal equipment to conduct cell optimization or network searching. The situation that the network information included in the first message is the network information of the cell where the first terminal equipment cannot reside due to the distance is avoided, so that the effective first message is higher in duty ratio, and the broadcasting and receiving effective rate of the first message is improved.

In addition, the first terminal device may be caused to communicate when it is detached from the mobile communication network based on a short-range (short-range) transmission protocol. Thus, the first terminal device and the second terminal device can communicate even if the first terminal device is not camping on any cell. Therefore, when the first terminal equipment needs to reside on the network, the network can be searched in time to reside on the network based on the first message, and the waiting time of the user is shortened.

Therefore, the first terminal device and the second terminal device can share information, so that each terminal device can acquire rich cell information without actively measuring surrounding cell information.

S200: the first terminal device searches for a target cell using a first message of at least one second terminal device and camps on the target cell when network preference and/or network searching is performed.

The network preference means that the terminal equipment currently resides in a certain cell, but because the cell has congestion, poor signal strength or other problems, the service quality provided by the cell for the terminal equipment is poor, and user experience is affected, and at this time, the terminal equipment needs to perform network preference to switch from the current serving cell to other cells, so as to improve user experience. Network searching refers to the process of searching the network to camp on a suitable cell when the terminal device is not currently camping on any cell, is not camping on the HPLMN or is camping on other network systems lower than the LTE network.

In this embodiment of the present application, after the first terminal device receives the first message, network preference and/or network searching may be performed based on network information included in the first message. For example, when the first terminal device performs network optimization, since the first message includes the RSRQ and the RSRQ of the serving cell and the neighboring cells of the second terminal device, the first terminal device may determine whether there is a cell with stronger signal strength around the first terminal device based on the RSRQ and the RSRQ of the serving cell, the RSRQ and the RSRQ of the serving cell and the neighboring cells of the second terminal device, the service experience information of the serving cell, and the like, so as to facilitate the cell handover of the second terminal device. The first terminal device can also directly search the cell based on the frequency point of the serving cell of the second terminal device in the first message without frequency sweep. When the first terminal device performs network searching, the first terminal device may directly select a suitable PLMN from the PLMN list in the second message, without performing a PLMN searching step.

For the fifth scenario, when the quality of experience of the terminal device serving cell is poor, the terminal device may learn that the surrounding cell has better service experience based on RSRP, RSRQ information, and the like included in the first message, and the terminal device may directly search for the network to reside based on the first message.

For the first scenario, after the flight mode is turned off, the first terminal device may directly select a PLMN based on the PLMN list in the first message, and then search for a cell based on the frequency point information in the first message. The network searching and residing steps are simple, and the network searching and residing time can be shortened.

For scenario two, after the first terminal device receives the first message, it may be known that the HPLMN network already exists. The first terminal device may then select the HPLMN directly based on the first message and search for a cell based on the frequency point information in the first message. Compared with the method for actively searching the network by the terminal equipment based on the network configuration, the method provided by the embodiment of the invention has the advantages that the first terminal equipment can timely know that the HPLMN network exists around the first terminal equipment, the network searching and residing steps are simple, and the time for switching the first terminal equipment to the HPLMN can be shortened.

For the third scenario, the first terminal device may also learn that the HPLMN network exists in time, so as to shorten the network searching residence time of the first terminal device.

For the fourth scenario, the first terminal device may timely learn that the LTE network exists based on the RAT information. Therefore, the first terminal equipment can directly skip the periodical network searching, directly execute the steps of searching cells and the like based on the frequency point information in the first message, and shorten the network searching and residing time.

For the sixth scenario, the first terminal device may learn that an LTE network or an SA network exists in time based on the RAT information, and may directly perform steps of searching for a cell based on the frequency point information in the first message, so as to shorten the network searching residence time.

Therefore, according to the information sharing method provided by the embodiment of the application, no matter in which application scene the first terminal equipment is, the network searching and residing can be timely performed, the network searching and residing steps are simple, and the time consumption is short.

According to the technical scheme, the information sharing method can be used for sharing information among different terminal devices, so that the terminal devices do not need to actively measure information of surrounding cells, network searching and network residence can be directly performed based on the information shared by other terminal devices, network searching and residence time is shortened, and user experience is improved.

Fig. 5 is a schematic flow chart of receiving a first message by a first terminal device according to an embodiment of the present application, as shown in fig. 5, in an embodiment of the present application, step S100 may include the following steps S101 to S104:

S101: and starting a first timer, wherein the first timer is periodically overtime with a first preset duration.

The first timer may be a timer configured on the first terminal device and the second terminal device, and the first timer may be used for recording a time interval of the first terminal device receiving the first message, or may be used for recording a time interval of the second terminal device broadcasting the first message. The timing periods of the first timers of different terminal devices can be unified and periodically overtime at the same time point, so that communication connection can be established between the first terminal device and the second terminal device at the appointed time (the time of overtime of the first timer), and the first terminal device can successfully receive the first message when the second terminal device broadcasts the first message.

The first preset duration may be, for example, equal to 5 minutes, 10 minutes, or 15 minutes, which is not specifically limited in the embodiments of the present application.

In this embodiment of the present application, besides the first timer may be used as a trigger condition for the terminal device to receive the first message, the terminal device may be triggered by other conditions, for example, the service quality of the serving cell of the first terminal device is poor, and may also be used as a trigger condition for the terminal device to receive the first message. The above triggering conditions will be described in detail below, and will not be described here again.

S102: the first terminal device determines whether the first timer has timed out.

It will be appreciated that the first timer includes two states, one being a timed-out state and the other being a timeout state. When the first timer is in a timeout state, a signal may be generated indicating that the first timer has timed out, and the first terminal device may respond to the signal and know that the first timer has timed out. Thus, in the step of the first terminal device determining whether the first timer has expired, if the first terminal device receives the signal, the first terminal device may determine that the first timer has expired, and if the first terminal device does not receive the signal, the first terminal device may determine that the first timer has not expired.

S103: if the first timer is overtime, the first terminal device judges whether the historical receiving times are smaller than or equal to a first preset threshold value, wherein the historical receiving times are times that the first terminal device receives the first message in a second preset duration before the first timer is overtime.

Wherein if the first timer has timed out, it indicates that the first terminal satisfies a trigger condition for receiving the first message. In the embodiment of the present application, after the triggering condition for receiving the first message is met, the method further includes a step of determining whether the historical receiving times of the first terminal device is less than or equal to a first preset threshold value, so as to restrict the times of receiving the first message by the first terminal device, avoid unnecessary resource waste, and reduce energy consumption.

It can be understood that if the number of times of historical reception of the first terminal device is too large, this means that the frequency of receiving the first message by the first terminal device is too fast, and there is a small possibility that the first message received by the first terminal device multiple times in a short time may have a difference, which results in unnecessary resource waste of the first terminal device. Therefore, in the embodiment of the application, whether the first message needs to be received or not can be determined based on the historical receiving times.

Illustratively, the second preset duration may be 1 hour and the first preset threshold may be equal to 6 times. Thus, if the first terminal device receives the first message more than 6 times within 1 hour before the first timer times out, the first terminal device will not receive the first message even if the first timer times out, thus, the first message with too high overlap ratio can be avoided to be received, and the energy consumption can be reduced.

It will be appreciated that after the first timer times out, the first timer may be reset directly to begin timing again and wait for the next timeout.

In this embodiment of the present application, the second preset duration is not limited to 1 hour, the first preset threshold is not limited to 6 times, and specific values may be determined according to practical situations, which is not limited in this embodiment of the present application, and it is only required to ensure that the timeout number of times of the first timer is less than or equal to the first preset threshold in the second preset duration.

S104: and if the historical receiving times are smaller than or equal to a first preset threshold value, the first terminal equipment receives the first message.

Therefore, the embodiment of the application can jointly determine whether to receive the first message based on the first timer and the historical receiving times, so that the times of communication between the first terminal device and the second terminal device can be reduced, invalid communication between the first terminal device and the second terminal device is avoided, the memory space of the first terminal device occupied by the first message is reduced, and the energy consumption is reduced.

It may be appreciated that, in the embodiment of the present application, the timeout number of the first timer may be less than or equal to the first preset threshold within the second preset duration. If the first timer is not triggered to receive the first message except for the first timer which is overtime within the second preset time before the first timer is overtime, the first timer can trigger the first terminal equipment to receive the first message every time the first timer is overtime. If there are other events triggering the reception of the first message than the first timer times out, the first timer may not trigger the reception of the first message this time out.

For example, the first preset duration of the first timer is equal to 15 minutes, the second preset duration is equal to 1 hour, the first preset threshold is equal to 4 times, and then the timeout of the first timer within 1 hour is equal to 3 times. In the case that the first timer times out to trigger the first message to be received, and no other triggering condition triggers the first message to be received, the first timer can trigger the first terminal device to receive the first message every time the first timer times out. If the service quality of the serving cell of the first terminal device is poor and the first message is triggered to be received for 2 times before the first timer times out, the historical receiving times of the first terminal device are 5 times and are larger than the first preset threshold value, and the first timer times out and cannot trigger the first terminal device to receive the first message.

It should be noted that, in the embodiment of the present application, the searched network information may be network information searched by triggering the search between two times of timeout adjacent to the first timer by the second terminal device, so that the real-time performance of the network information is better, and if the first terminal device performs network optimization or network search based on the network information, the success rate is higher.

Fig. 6 is a flow chart illustrating a sub-step of step S103 according to an embodiment of the present application.

In some implementations, as shown in fig. 6, step S103 includes the following steps S1031-S1032:

s1031: if the first timer has timed out, the first terminal device judges whether the residual electric quantity is larger than a second preset threshold value.

If the first timer has timed out, the first terminal device meets the triggering condition of receiving the first message, and in this embodiment of the present application, after the triggering condition of receiving the first message is met, the method further includes a step of determining whether the remaining power of the first terminal device is greater than a second preset threshold, so as to restrict the number of times that the first terminal device receives the first message. Therefore, the action of receiving the first message can be prevented from running frequently when the residual electric quantity is small, so that the power consumption of the first terminal device is overlarge, and the normal running of other functions of the terminal device is prevented from being influenced. For example, the second preset threshold may be equal to 30%, 25% or 20%, and the value of the second preset threshold is not specifically limited in the embodiments of the present application.

S1032: and if the residual electric quantity is larger than a second preset threshold value, the first terminal equipment judges whether the historical receiving times are smaller than or equal to the first preset threshold value.

For example, the second preset threshold may be equal to 30%, and when the first timer has timed out and the remaining power of the first terminal device is greater than 30%, the first terminal device determines whether the number of times of historical reception is less than or equal to the first preset threshold. In this way, the first timer, the residual electric quantity and the historical receiving times can jointly restrict whether the first terminal device receives the first message or not, and unnecessary resource waste can be avoided.

Further, with continued reference to fig. 5, in the embodiment of the present application, step S100 further includes the following steps S105 to S107:

s105: if the first timer is not overtime, the first terminal device judges whether the service quality of the service cell is lower than a third preset threshold, wherein the service quality at least comprises the reference signal receiving power, the reference signal receiving quality or the signal-to-interference-plus-noise ratio of the cell.

If the first timer is not timed out and the service quality of the service cell of the first terminal device is poor, the first terminal device has a network optimization requirement, and if the service quality of the service cell of the first terminal device is too poor, the first terminal device can have a network searching requirement until the first terminal device is in an OOS state. Therefore, when the first timer does not expire, the embodiment of the application may consider the current network state of the first terminal device, so as to determine whether to receive the first message. The first message is received when network preference or network searching is required, so that the utilization rate of the first message can be improved.

The service quality of the service cell may refer to the quality of service that the service cell can provide for the terminal device, and the better the service quality of the service cell, the better the network state of the terminal device residing in the cell, the smoother the network usage of the terminal device, for example, the smoother the video viewing or the faster the loading of the web page. In practical applications, the terminal device may determine whether the serving cell can provide good quality of service based on the state of the reference signal. Specifically, the terminal device may receive the reference signal and use information carried by the reference signal as a criterion for determining the current quality of service of the serving cell. In summary, the service quality of the serving cell may include RSRP, RSRQ, and SINR, and if RSRP, RSRQ, or SINR is lower than a third preset threshold, it is determined that the service quality of the serving cell is poor, and if RSRP, RSRQ, or SINR is equal to or higher than the third preset threshold, it is determined that the service quality of the serving cell is good. After the terminal device receives the reference signal, the service quality of the serving cell can be determined. The terminal device may also select a handover cell if it is determined that the quality of service of the serving cell is poor.

The embodiment of the application may consider that the service quality of the serving cell is poor when the RSRP, the RSRQ and/or the SINR is lower than a third preset threshold, and consider that the service quality of the serving cell is better when the RSRP, the RSRQ and/or the SINR is equal to or higher than the third preset threshold. In practical application, different parameters are adopted to judge the quality of service of the service cell, and different third preset thresholds can be set. For example, when RSRP is used as the judgment parameter, the third preset threshold may be equal to-105 dBm, and if RSRP of the serving cell is less than-105 dBm, the service quality of the serving cell is poor. When RSRQ is used as the judgment parameter, the third preset threshold may be equal to-19.5, and if RSRQ of the serving cell is less than-19.5, the service quality of the serving cell is poor.

It will be appreciated that the types of serving cells are different, as are the reference signals. For example, when the serving cell is an LTE cell, the reference signal may be a CRS signal. When the serving cell is an SA cell, the reference signal may be an SSB signal, which is not specifically limited in this application.

In some implementations, whether the video of the terminal device is smooth or not, and the user experience information such as the loading speed of the webpage can also be represented by the data quality of the time delay of the TCP data packet. If the delay of the TCP data packet is longer, the video is easy to be blocked when the terminal equipment watches, and the webpage loading is slower, so that the service quality of the service cell is also poorer. If the time delay of the TCP data packet is shorter, the video is not easy to be blocked when the terminal equipment watches, the webpage loading is smooth, and the service quality of the service cell is better.

In other implementations, whether the video of the terminal device is watched smoothly and the user experience information such as the web page loading speed is low or not can also be represented by the data quality of the throughput rate of the network transmission data, it can be understood that if the throughput rate of the network transmission data is low, the video is watched by the terminal device and is easy to be blocked, the web page loading speed is low, and the service quality of the service cell is poor.

Therefore, the embodiment of the application can reflect the quality of service from the angles of the related parameters of the reference signal, time delay, throughput rate and the like.

S106: and if the service quality of the service cell is lower than a third preset threshold, the first terminal equipment judges whether the historical receiving times are smaller than or equal to the first preset threshold.

S107: and if the historical receiving times are smaller than or equal to a first preset threshold value, the first terminal equipment receives the first message.

It can be appreciated that when the service quality of the serving cell is lower than the third preset threshold and the historical number of times of reception is less than or equal to the first preset threshold, the first terminal device should receive the first message, so that the first terminal device can optimize the network state thereof based on the first message, and improve the user experience.

With continued reference to fig. 5, in the embodiment of the present application, after step S103 or step S106, the following steps may further be included: if the historical reception times are larger than a first preset threshold value, the first terminal equipment re-executes the step of judging whether the first timer is overtime.

It may be understood that, if the first timer has timed out, or the service quality of the serving cell is lower than the third preset threshold, but the historical number of times of reception is greater than the first preset threshold, in order to avoid resource waste, in this embodiment, the first terminal device does not receive the first message, and continues to wait for the next timeout of the first timer.

In this embodiment, after step S105, the method may further include the following steps: if the service quality of the serving cell is equal to or higher than a third preset threshold, the first terminal device re-executes the step of judging whether the first timer is overtime.

With continued reference to fig. 5, in the embodiment of the present application, after step S100, the following step S300 is further included:

s300: the first terminal equipment judges whether the first message contains effective network information or not; the effective network information is network information with the broadcast intensity in the first message being greater than a fourth preset threshold value.

If the network information contained in the first message is not valid network information, the first terminal device may easily cause network preference or network search failure when performing network preference and/or network search. Therefore, in order to avoid the problem of network preference or network search failure, the embodiment of the present application further includes a step of determining whether the network information included in the first message is valid network information before performing network preference or network search based on the first message, so as to improve success rates of network preference and network search.

It can be understood that, under the support of the mobile communication technology, the terminal device should reside in the surrounding cells, so that the signal strength of the serving cell of the terminal device can be ensured to be strong, and the residence experience is good. Thus, when the second terminal device is too far from the first terminal device, the network information measured by the first terminal device is not suitable for the first terminal device to perform network preference and/or network search. In the embodiment of the application, when the first terminal device receives the first message broadcast by the second terminal device, the distance between the first terminal device and the second terminal device may be determined based on the broadcast strength of the second terminal device when the first message is broadcast. The stronger the broadcast intensity is, the closer the distance between the first terminal equipment and the second terminal equipment is, and the network information obtained by the measurement of the second terminal equipment is more suitable for the first terminal equipment to perform network optimization and/or network searching.

The specific value of the fourth preset threshold may be determined according to a communication manner between the first terminal device and the second terminal device. For example, when the first terminal device and the second terminal device use bluetooth communication, the broadcast strength of the network information may be measured by the signal strength (received signal strength indication, RSSI) at the time of wireless reception. The fourth preset threshold may be equal to-60 dBm, and when the first terminal device is in communication with the second terminal device, if the first terminal device senses that the bluetooth RSSI of the opposite second terminal device is less than or equal to-60 dBm, the network information included in the first message broadcast by the second terminal device is invalid network information. If the first terminal device senses that the Bluetooth RSSI of the opposite second terminal device is greater than-60 dBm, the network information included in the first message broadcast by the second terminal device is valid network information.

It will be appreciated that if there are a plurality of second terminal devices around the first terminal device after the first timer expires, the first terminal device may communicate with the plurality of second terminal devices in sequence and receive a plurality of first messages. Then, when step S300 is performed, the part of the first message contains valid network information and the part of the first message does not contain valid network information, which is affected by the difference in distance between the different second terminal device and the first terminal device. In the embodiment of the application, the first message which does not contain the effective network information can be deleted directly, so that the occupied memory space is avoided.

In some implementations, embodiments of the present application may further include: after receiving the new first message, the first terminal device stores the latest first message in the memory, and deletes the historical first message stored in the memory at the same time, so as to avoid interference of the historical first message which is longer than the current moment on network optimization and/or network searching when the first terminal device performs network optimization and/or network searching, and save memory space.

With continued reference to fig. 5, in an embodiment of the present application, step S200 includes the following steps S201-S203:

S201: the first terminal equipment judges whether the service quality of the service cell is lower than a third preset threshold value.

It can be understood that when the service quality of the serving cell is low, the first terminal device may perform network optimization to switch to reside in a cell with better service quality, so as to improve the user experience. The embodiment of the application can judge whether the first terminal equipment needs to perform network optimization after receiving the first message, and if so, the network optimization can be performed directly based on the first message.

In some implementations, the quality of service of the serving cell may include RSRP, RSRQ, or SINR, and if the RSRP, RSRQ, or SINR is lower than a third preset threshold, the quality of service of the serving cell is determined to be poor, and if the RSRP, RSRQ, or SINR is equal to or higher than the third preset threshold, the quality of service of the serving cell is determined to be good.

In other implementations, the delay of the TCP packet or the throughput rate of the network transmission data may be used to determine the quality of service of the serving cell, which is not described herein.

In this embodiment of the present application, the first terminal device may periodically determine whether the service quality of the serving cell is lower than a third preset threshold. Specifically, the first terminal device may be provided with a third timer, the third timer may timeout periodically with a first preset duration, and the timeout time of the third timer is later than the timeout time of the first timer. In this way, after the first terminal device receives the first message, if the service quality of the serving cell is poor, network preference can be performed directly based on the first message. The periodic judgment mode can reduce energy consumption. The first terminal device can also judge whether the service quality of the service cell is lower than a third preset threshold value in real time, so that whether the service cell is suitable for residence can be timely found and determined, and when the service cell is not suitable for residence, the cell can be timely switched, and the user experience is improved.

S202: and if the service quality of the service cell is lower than a third preset threshold value, the first terminal equipment determines whether effective network information meeting the real-time requirement exists or not based on the moving state.

If the service quality of the service cell is lower than the third preset threshold, the service quality of the service cell of the first terminal equipment is poor, and the first terminal equipment can perform network optimization switching to other cell residence. Further, in order to determine whether the effective network information is suitable for the first terminal device to perform network searching, the embodiment of the application further includes determining whether the real-time performance of the effective network information meets the requirement based on the mobile state of the first terminal device.

Specifically, if the first terminal device is far away from the location where the first message was received after the first message is received, the first terminal device may have been or will be out of coverage of the cell corresponding to the valid network information. For example, when the first terminal device is in a high-speed moving state, for example, when the user carries the first terminal device with a vehicle, the first terminal device can quickly move between coverage areas of different cells, and at this time, the cell corresponding to the valid network information is no longer suitable for the first terminal device to reside. If the first terminal device needs to perform network optimization, the first terminal device cannot directly use the effective network information to perform cell residence, but needs to perform measurement by itself. Therefore, the success rate of network switching of the first terminal equipment can be improved, and the situation that network switching fails due to the fact that effective network information with poor real-time performance is utilized for network switching is avoided, so that poor user experience is caused.

In practical application, whether the effective network information meets the real-time requirement can be determined based on the real-time moving speed of the first terminal equipment. For example, if the real-time moving speed of the first terminal device is less than or equal to 100km/h, the effective network information satisfies the real-time requirement, and if the real-time moving speed of the first terminal device is greater than 100km/h, the effective network information does not satisfy the real-time requirement.

S203: if the effective network information meeting the real-time requirement exists, the first terminal equipment performs cell search based on the effective network information meeting the real-time requirement, and a target cell is determined.

In the embodiment of the application, the first terminal device performs cell search based on the effective network information meeting the real-time requirement, so that the network optimization time can be shortened, and the success rate of the network optimization can be improved.

Specifically, after resolving the effective network information meeting the real-time requirement, the first terminal device can at least obtain PLMN identification, PCI, frequency point, RAT information, RSRP, RSRQ, SINR and service experience information of the serving cell of the second terminal device, and RSRP and RSRQ of the neighboring cells of the second terminal device. In some cases, the first terminal device may also obtain all PLMN information that the second terminal device may search for, and PCI, cell frequency point, RAT information, RSRP, ESEQ, SINR, service experience information, etc. of the new serving cell of the second terminal device. It can be seen that, based on the effective network information meeting the real-time requirement, there are one or more cells for the first terminal device to select, so the first terminal device needs to screen the effective network information meeting the real-time requirement, and finally determines the target cell.

In practical application, the first terminal device may obtain a cell with the strongest RSRP (cell signal strength) by comparing the sizes of the resolved RSRP, and take the cell with the strongest RSRP as the target cell. It should be noted that, if the cell corresponding to the effective network information meeting the real-time requirement does not include the serving cell of the first terminal device, the RSRP of the serving cell of the first terminal device and the RSRP resolved by the first terminal device need to be compared together to determine the cell with the strongest RSRP. In this way, a handover of the first terminal device to another cell with a weaker signal strength than the current serving cell can be avoided. For example, when the first terminal device is in an area with a larger cell density, it may happen that the serving cell of the second terminal device and the neighboring cell do not include the serving cell of the first terminal device.

In some implementations, the target cell may also be determined by comparing parameters such as RSRQ or SINR, which is not specifically limited in this application.

Further, after determining the target cell, the first terminal device may camp on the target cell. Specific residence steps may include: the first terminal equipment searches on the frequency point of the target cell, and acquires the PCI of the cell after the cell is searched. And comparing the acquired PCI with the PCI of the target cell obtained by analyzing the effective network information to check whether the searched cell is the target cell or not, so that the first terminal equipment can be ensured to smoothly reside in the target cell with strong signal strength.

In some implementations, if the cell searched by the first terminal device fails the PCI check, or the residence fails due to a problem of congestion of the searched cell. The first terminal device may continue to camp on the previous serving cell to ensure continuity of network service. The first terminal device may also re-perform network measurements and determine the camping cell based on the measurements.

It should be noted that, if the target cell is a neighboring cell of the second terminal device, after determining the target cell, the first terminal device may directly perform cell search, where the first terminal device does not need to sort the results of cell search according to signal strength, and only needs to find the target cell from the cell search results to reside, so that the network optimization time of the first terminal device may be shortened.

It should be noted that, in the embodiment of the present application, after step S201, the following steps may further be included: if the service quality of the serving cell is equal to or higher than a third preset threshold, the first terminal device re-executes the step of judging whether the first timer is overtime. After step S202, the following steps may be further included: if no effective network information meeting the real-time requirement exists, the first terminal equipment re-executes the step of judging whether the first timer is overtime. After step S203, the method further includes the following step S204: the first terminal device resides in a target cell.

With continued reference to fig. 5, in an embodiment of the present application, step S200 includes the following steps S205-S207:

s205: the first terminal equipment judges whether network searching requirements exist.

In practical application, there are many scenarios where the first terminal device needs to search for a network, for example, the first terminal device is in a roaming scenario, in a border roaming scenario, in an OOS scenario, in CDMA, in GSM or WCDMA, and the first terminal device has a network searching requirement and triggers the network searching. When the first terminal equipment has network searching requirements, network searching can be directly performed based on effective network information, and therefore network searching time can be shortened.

S206: if the network searching requirement exists, the first terminal equipment determines whether effective network information meeting the real-time requirement exists or not based on the moving state.

The reason for triggering the first terminal device to be in the network searching scene may be that the first terminal device is in a high-speed moving state. Further, if the first terminal device is in a high-speed moving state, the first terminal device can rapidly move between coverage areas of different cells, and at this time, the cell corresponding to the valid network information is no longer suitable for the first terminal device to reside. Therefore, the embodiment of the application can judge whether the effective network information meets the real-time requirement based on the network state of the first terminal equipment. For example, the determination may be based on the real-time moving speed of the first terminal device, which is not described herein.

S207: if the effective network information meeting the real-time requirement exists, the first terminal equipment performs cell search based on the effective network information meeting the real-time requirement, and a target cell is determined.

Specifically, after resolving the effective network information meeting the real-time requirement, the first terminal device can at least obtain PLMN identification, PCI, frequency point, RAT information, RSRP, RSRQ, SINR and service experience information of the serving cell of the second terminal device, and RSRP and RSRQ of the neighboring cells of the second terminal device. In some cases, the first terminal device may also obtain all PLMN information that the second terminal device may search for, and PCI, cell frequency point, RAT information, RSRP, ESEQ, SINR, service experience information, etc. of the new serving cell of the second terminal device. The first terminal device may select a suitable target PLMN from a plurality of PLMN identities. And then taking a cell corresponding to the cell frequency point as a target cell based on the cell frequency point corresponding to the target PLMN and the target PLMN. If the target PLMN corresponds to a plurality of cell frequency points, the first terminal device may use the cells corresponding to the plurality of cell frequency points as candidate cells, obtain the candidate cell with the strongest RSRP by comparing the sizes of RSRP (cell signal strength) of the candidate cells, and use the candidate cell with the strongest RSRP as the target cell.

Further, after determining the target cell, the first terminal device may camp on the target cell. Specific residence steps may include: the first terminal equipment searches on the frequency point of the target cell, and acquires the PCI of the cell after the cell is searched. And comparing the acquired PCI with the PCI of the target cell obtained by analyzing the effective network information to check whether the searched cell is the target cell or not, so as to ensure that the first terminal equipment can smoothly reside in the target cell.

In some implementations, if the cell searched by the first terminal device fails the PCI check, or the residence fails due to a problem of congestion of the searched cell. The first terminal device may also re-perform network measurements and determine the camping cell based on the measurements.

It should be noted that, if the target cell is a neighboring cell of the second terminal device, after determining the target cell, the first terminal device may directly search the cell, and then the first terminal device does not need to sort the results of the cell search according to the signal strength, but only needs to find the target cell from the cell search results to reside, so as to shorten the time of network searching of the first terminal device.

It should be noted that, in the embodiment of the present application, after step S205, the following steps may be further included: if the network searching requirement does not exist, the first terminal equipment re-executes the step of judging whether the first timer is overtime. After step S206, the following steps may be further included: if no effective network information meeting the real-time requirement exists, the first terminal equipment re-executes the step of judging whether the first timer is overtime. After step S207, the following step S208 is further included: the first terminal device resides in a target cell.

The flow of the broadcaster of the first message is exemplarily described below with reference to the accompanying drawings.

Fig. 7 is a flowchart of a second information sharing method provided in an embodiment of the present application, and as shown in fig. 7, the information sharing method provided in the embodiment of the present application includes the following steps S400 to S500:

s400: the second terminal equipment acquires a first message, wherein the first message comprises network information of a service cell of the second terminal equipment, network information of a neighboring cell of the second terminal equipment and/or network information of a cell searched by the second terminal equipment.

The terminal equipment has more comprehensive perception to the service cell, has a certain perception capability to the neighbor cells of the service cell, and simultaneously has rich perception to the information of a plurality of surrounding cells when the terminal equipment searches the network again. The sharing of the respective known network information between the terminal devices may enable the terminal devices receiving the network information to also learn rich information, so that the terminal devices may save the procedure of cell measurement in the steps of selecting a cell or switching a cell, etc. Therefore, in the embodiment of the present application, the second terminal device may package the network information to form the first message and share the first message with other terminal devices.

The network information of the serving cell includes Public Land Mobile Network (PLMN) identification, physical Cell Identification (PCI), cell frequency point, radio Access Technology (RAT) information, reference Signal Received Power (RSRP), reference Signal Received Quality (RSRQ), signal-to-interference plus noise ratio (SINR) and service experience information of the serving cell, where the service experience information refers to evaluation information when the serving cell provides service support for the terminal device, and for the terminal device, the service experience information provided by the serving cell is better, indicating that the serving cell is more suitable for residence. In practical application, the quality of service experience can be judged based on parameters such as TCP data packet delay or throughput rate of the terminal equipment. The network information of the neighboring cell includes at least RSRP and RSRQ of the neighboring cell. The adjacent cell refers to a cell which is in a switching relation with the service cell, and coverage areas of the adjacent cell and the service cell are overlapped. Since a cell may have multiple neighboring cells, in this embodiment of the present application, network information of multiple neighboring cells of a serving cell may be packaged in a first message and broadcast to a first terminal device.

It can be understood that the second terminal device may acquire the network information of the serving cell and the network information of the neighboring cell in real time, or may acquire the network information of the cell after searching the network.

S500: the second terminal device broadcasts a first message to the surrounding first terminal devices.

Wherein the second terminal device and the first terminal device are terminal devices that can realize mobile communication and that can perform short-range (short-range) communication between terminals. Specifically, the first terminal device and the second terminal device may communicate based on a short-distance (short-range) transmission protocol, for example, the communication manner of the first terminal device and the second terminal device may be bluetooth, wi-Fi, zigBee, or the like. In this way, the network information included in the first message is more suitable for the first terminal device to perform cell preference or network searching, so that the effective rate of broadcasting the first message by the second terminal device can be improved.

It will be appreciated that one second terminal device may broadcast a first message to one or more first terminal devices in the vicinity. In this way, as many first terminal devices as possible can be made to receive the first message. The second terminal device can also broadcast the first message to the specific first terminal device so as to reduce energy consumption, and simultaneously improve the utilization rate of the first message and avoid invalid communication. The specific first terminal device may be the terminal device closest to the second terminal device.

It can be seen that information sharing can be performed between the second terminal device and the first terminal device, so that each terminal device can acquire rich cell information without actively measuring surrounding cell information.

Fig. 8 is a schematic flow chart of broadcasting a first message by a second terminal device according to an embodiment of the present application, as shown in fig. 8, in an embodiment of the present application, step S500 includes the following steps S501 to S504:

S501: and starting a second timer, wherein the second timer is periodically overtime in a third preset duration.

The second timer may be a timer configured on the second terminal device and the first terminal device, where the second timer is used to record a time interval of broadcasting the first message by the second terminal device, and may also be used to record a time interval of receiving the first message by the first terminal device. The timing periods of the second timers of the different terminal devices are unified. And periodically overtime at the same time point, so that communication connection can be established between the second terminal equipment and the first terminal equipment at the appointed time (the overtime time of the second timer), the first terminal equipment can be received when the second terminal equipment broadcasts the first message, and the broadcasting success rate of the first message is improved.

The third preset duration may be, for example, equal to 5 minutes, 10 minutes, or 15 minutes, which is not specifically limited in the embodiments of the present application.

It may be appreciated that in the embodiment of the present application, the third preset duration of the second timer may be equal to the first preset duration of the first timer. And the starting time and the overtime time of the second timer are the same as those of the first timer.

In this embodiment of the present application, besides the second timer may be used as a trigger condition for the terminal device to broadcast the first message, the terminal device may be triggered by other conditions, for example, the second terminal device may search for the network and may also be used as a trigger condition for the second terminal device to broadcast the first message. The above triggering conditions will be described in detail below, and will not be described here again.

S502: the second terminal device determines whether the second timer has expired.

S503: if the second timer is overtime, the second terminal device judges whether the historical broadcasting times are smaller than or equal to a fifth preset threshold value, wherein the historical broadcasting times are times of the second terminal device broadcasting the first message in a fourth preset duration before the second timer is overtime.

Wherein if the second timer has timed out, it indicates that the second terminal device satisfies a trigger condition for broadcasting the first message. In the embodiment of the present application, after the triggering condition of broadcasting the first message is met, the method further includes determining whether the historical broadcasting times of the second terminal device is less than or equal to a fifth preset threshold, so as to restrict the times of broadcasting the first message by the second terminal device, avoid unnecessary resource waste, and reduce energy consumption.

It will be appreciated that if the number of historical broadcasts by the second terminal device is too large, this means that the frequency of broadcasting the first message by the second terminal device is too fast, and there is a small possibility that the second terminal device will have a small difference between the first messages broadcast many times in a short time, resulting in unnecessary resource waste for the second terminal device and the first terminal device on the opposite side. Therefore, in the embodiment of the application, whether the first message needs to be broadcast or not can be determined based on the historical broadcast times.

Illustratively, the fourth preset duration may be 1 hour and the fifth preset threshold may be equal to 6 times. Thus, if the number of times the second terminal device broadcasts the first message within 1 hour before the second timer times out is greater than 6 times, the second terminal device will not broadcast the first message even if the second timer has timed out, and thus, it is possible to avoid broadcasting the first message with too high overlap ratio and reduce the power consumption.

In this embodiment of the present application, the fourth preset duration is not limited to 1 hour, the fifth preset threshold is not limited to 6 times, and specific values may be determined according to practical situations, which is not limited in this embodiment of the present application, and it is only required to ensure that the timeout number of the second timer is less than or equal to the fifth preset threshold within the fourth preset duration.

S504: and if the historical broadcasting times are smaller than or equal to a fifth preset threshold value, the second terminal equipment broadcasts the first message.

It may be appreciated that, in the embodiment of the present application, the timeout number of the second timer may be less than or equal to the fifth preset threshold within the fourth preset duration. If the second timer does not have other triggering conditions to trigger the time for broadcasting the first message except for the time that the second timer times out to trigger the first message within the fourth preset time before the time that the second timer times out, the second timer can trigger the second terminal equipment to broadcast the first message every time that the second timer times out. If there are other events triggering the broadcasting of the first message than the second timer times out, the second timer may not trigger the broadcasting of the first message this time out.

For example, the third preset duration of the second timer is equal to 15 minutes, the fourth preset duration is equal to 1 hour, the fifth preset threshold is equal to 4 times, and then the number of times of timeout in 1 hour in the first timer is equal to 3 times. In the case that the second timer times out to trigger broadcasting the first message, and no other triggering condition triggers broadcasting the first message, the second timer can trigger the second terminal device to broadcast the first message every time the second timer times out. If the second terminal device searches the network and triggers 2 times of broadcasting the first message before the second timer times out, the historical broadcasting times of the second terminal device are 5 times and are larger than the fifth preset threshold value, and the second timer times out and cannot trigger the second terminal device to broadcast the first message.

Therefore, the embodiment of the application can determine whether to broadcast the first message based on the second timer and the historical broadcast times, so that the times of communication between the second terminal equipment and the first terminal equipment can be reduced, invalid communication between the second terminal equipment and the first terminal equipment is avoided, and energy consumption is reduced.

It should be noted that, if the condition that triggers the second terminal device to broadcast the first message is that the second timer expires and the number of times of historical broadcasting is less than or equal to the fifth preset threshold, the first message only includes the network information of the serving cell of the second terminal device and the network information of the neighboring cell.

In some implementations, step S503 may include the following steps S5031-S5032:

s5031: if the second timer has timed out, the second terminal device judges whether the residual electric quantity is larger than a sixth preset threshold value.

If the second timer has timed out, the second terminal device meets the triggering condition of broadcasting the first message, and in this embodiment of the present application, after the triggering condition of broadcasting the first message is met, the method further includes a step of determining whether the remaining power of the second terminal device is greater than a sixth preset threshold, so as to restrict the number of times that the second terminal device broadcasts the first message. Therefore, the action of broadcasting the first message can be prevented from running frequently when the residual electric quantity is small, so that the power consumption of the second terminal device is overlarge, and the normal running of other functions of the terminal device is prevented from being influenced. Illustratively, the sixth preset threshold may be equal to 30%, 25% or 20%, and the value of the second preset threshold is not specifically limited in the embodiments of the present application.

S5032: and if the residual electric quantity is larger than a sixth preset threshold value, the second terminal equipment judges whether the historical broadcasting times are smaller than or equal to the fifth preset threshold value.

For example, the sixth preset threshold may be equal to 30%, and when the second timer has timed out and the second terminal device remaining power is greater than 30%, the second terminal device determines whether the number of historical broadcasting times is less than or equal to the fifth preset threshold. In this way, the second timer, the remaining capacity and the historical broadcasting times can jointly restrict whether the second terminal device receives the first message, so that unnecessary resource waste can be avoided.

Further, with continued reference to fig. 8, in the embodiment of the present application, step S500 further includes the following steps S505-S507:

s505: if the second timer does not time out, the second terminal device judges whether to trigger network searching.

Wherein when the second timer does not expire, if the second terminal device triggers a network search, the second terminal device will measure the situation of its surrounding cells, and may finally camp on a new serving cell. Therefore, the network information measured after the second terminal device triggers the network searching is broadcasted to the first terminal device, the first terminal device does not need to re-measure the surrounding cell condition, and the network optimization and/or network searching time of the first terminal device can be shortened.

S506: and if the network search is triggered, the second terminal equipment judges whether the historical broadcasting times are smaller than or equal to a fifth preset threshold value.

Therefore, whether the second terminal equipment broadcasts the first message can be constrained based on whether the second terminal equipment triggers network searching and the historical broadcasting times, and unnecessary resource waste can be avoided.

S507: and if the historical broadcasting times are smaller than or equal to a fifth preset threshold value, the second terminal equipment broadcasts the first message after network searching.

It can be appreciated that when the second terminal device triggers network searching and the number of historical broadcasting times is less than or equal to the fifth preset threshold, the second terminal device should broadcast the first message, so that the first terminal device can perform network optimization and/or network searching based on the network information with better real-time performance, and measurement does not need to be performed again.

It should be noted that, if the condition that the second terminal device is triggered to broadcast the first message is that the second terminal device triggers a network search and the number of times of historical broadcasting is less than or equal to a fifth preset threshold, the first message only includes network information searched by the second terminal device, and the network search should be performed between two adjacent times of timeout of the second timer.

With continued reference to fig. 8, in the embodiment of the present application, after step S503 or step S506, the following steps may further be included: if the historical broadcasting times are larger than a fifth preset threshold, the second terminal equipment re-executes the step of judging whether the second timer is overtime.

It can be understood that if the second timer has timed out, or the second terminal device has triggered the network searching, but the number of historical broadcasting times is greater than the fifth preset threshold, in order to avoid resource waste, in the embodiment of the present application, the second terminal device does not broadcast the first message, but continues to wait for the next timeout of the second timer.

In this embodiment, after step S505, the following steps may further be included: if the network search is not triggered, the second terminal device re-performs the step of determining whether the second timer has timed out.

It will be appreciated that the same terminal device may become the broadcaster of the first message and may also become the recipient of the first message.
