Description

Network residence method and related equipment

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a network residence method and related devices.

Background

Currently, watches supporting embedded subscriber identity modules (embedded subscriber identity module, ESIM) perform cell search and cell registration after the bluetooth connection with the phone is broken. When the watch performs cell search and cell registration, the following two situations exist: (1) if the history frequency point exists, the watch performs cell search based on the history frequency point to obtain cell information of a cell on the history frequency point; then, a cell is selected for registration. Thus, there are cases where the signal of the cell in which the wristwatch is ultimately registered is poor. (2) If no history frequency point exists, the watch performs full-band network searching to read the cell information of the strongest signal cell on each frequency point; then, a cell is selected for registration. This results in a watch standing for a longer period of time.

Therefore, how to quickly select a cell with better signal strength for registration after the bluetooth connection between the watch and the mobile phone is disconnected becomes a problem to be solved.

At present, after the Bluetooth connection between the watch supporting the ESIM and the mobile phone is disconnected, the watch can control a modem (modem) to be powered on, so that the ESIM is powered on, and then cell search and cell registration can be performed. The watch has the following problems in the process of cell search and cell registration: (1) the signal of the cell in which the watch is finally registered is poor; (2) the watch has a longer residence time.

In the following, an application scenario of the network residence method provided in the embodiments of the present application will be described with reference to fig. 1a to 1c, taking a bluetooth connection as an example of a short-range wireless communication connection between a first device and a second device.

Fig. 1a is a schematic diagram of a short-range wireless communication system according to an embodiment of the present application. As shown in fig. 1a, the first device 101 is a smart phone and the second device 102 is a smart watch. Both the first device 101 and the second device 102 have bluetooth functionality enabled and a communication connection is established between the first device 101 and the second device 102 via bluetooth.

As shown in fig. 1b, after the application is set for the first device 101 to be started, a default user interface provided by the application is set. The user interface may include: flight mode, wiFi, bluetooth, personal hot spot, mobile network, etc. The first device 101 may detect a touch operation by a user on different function options in the user interface 11, in response to which the first device 101 may switch on or off the functions of the flight mode, wiFi, bluetooth, personal hot spot, mobile network, etc.

The "bluetooth" option 111 in the user interface is used to turn on or off the bluetooth function of the first device 101, which may be used to make a short-range wireless communication connection with the second device 102. The "bluetooth" option 111 includes a setting switch 111A, and the setting switch 111A can detect a touch operation by the user, and in response to the operation, the first device 101 turns on or off the bluetooth function. Illustratively, the bluetooth function is in an off state when the main color displayed by the switch 111A is white, and in an on state when the main color displayed by the switch 111A is gray.

As shown in fig. 1b, the first device 101 may detect a touch operation by the user on the setting switch 111A, and in response to the operation, the first device 101 turns off the bluetooth function, and the main color of the setting switch 111A changes from gray to white.

The connection prompt box 222 is used to indicate that the bluetooth connection between the second device 102 and the first device 101 is successful or disconnected. For example, "bluetooth connection has been disconnected" and "bluetooth connection is successful" may be displayed in the connection prompt box 222. Illustratively, if the second device 102 detects that the Bluetooth connection with the first device 101 has been broken, then a "Bluetooth connection broken" is displayed in the connection prompt box 222. At this time, the second device 102 may select a cell to register based on cell information including cell identities of the cells obtained by sorting the signal strengths of the cells in order from strong to weak.

The network residence method provided in the embodiment of the present application is described in detail below.

Referring to fig. 2, fig. 2 is a flow chart of a network residence method according to an embodiment of the present application. As shown in fig. 2, the network residence method may include, but is not limited to, the following steps:

s201, the second device detects whether the short-range wireless communication connection with the first device is disconnected.

The short-distance wireless communication means a technology that the furthest distance can reach more than 100m, and the technology such as semiconductor communication, wireless communication, electronic network and the like is utilized to effectively connect, so that wireless information transmission is realized within the range of 100 m. In short, a communication system is a communication system that uses the property of an electromagnetic wave signal that can propagate in free space to exchange information.

Alternatively, the short-range wireless communication connection may include, but is not limited to, a wireless fidelity (wireless fidelity, WIFI) connection, a bluetooth connection, a near field wireless communication (near field communication, NFC) connection, and the like.

And S202, if the second equipment detects that the short-distance wireless communication connection with the first equipment is disconnected, selecting a cell for registration based on cell information, wherein the cell information comprises cell identifications of cells obtained by sequencing the signal strengths of the cells from strong to weak.

Alternatively, the cell information may be sent by the first device to the second device, or may be pre-stored by the second device, which is not limited herein.

In an alternative embodiment, the second device selects a cell for registration based on the cell information, and may use the following manner: and selecting cells in sequence for registering according to the sequence from strong to weak signal strength of each cell in the cell information until the registration is successful. Therefore, on one hand, the second equipment can select the cell with better signal strength to register, and on the other hand, the success rate of cell registration can be improved.

For example, it is assumed that the cell information includes cell information of each of 5 cells, and cell identifiers of the 5 cells are, for example, cell 1, cell 2, cell 3, cell 4, and cell 5, where the 5 cells are ordered in order of strong to weak cell signal strengths, and the obtained cell identifiers are, in order, cell 3, cell 2, cell 5, cell 4, and cell 1. In this case, the second device may first select the cell 3 for registration, and if the registration is successful, determine to successfully camp on the cell 3, so that the mobile network may be normally used based on the cell 3. If the registration fails, the cell 2, the cell 5, the cell 4 and the cell 1 can be sequentially selected for registration until the registration is successful.

Optionally, if the second device detects that the short-distance wireless communication connection with the first device is disconnected, the second device may control the modem to power up, so that the ESIM powers up, and selects a cell to register based on the cell information.

In the embodiment of the application, the second device detects whether the short-distance wireless communication connection with the first device is disconnected; and if the second equipment detects that the short-distance wireless communication connection with the first equipment is disconnected, selecting a cell for registration based on cell information, wherein the cell information comprises cell identifications of cells obtained by sequencing the signal strengths of the cells from strong to weak. It can be seen that the second device can quickly select a cell with better signal strength for registration based on the cell information when detecting that the short-range wireless communication connection with the first device has been disconnected. Therefore, the time for the second equipment to register the cell can be saved, and the second equipment can register the cell with better signal under the condition that the signal of the cell on the history frequency point is weak and the signal of the cell on the non-history frequency point is strong.

Referring to fig. 3, fig. 3 is a flow chart of another network residence method according to an embodiment of the present application. The difference from the network residence method shown in fig. 2 is that in the network residence method shown in fig. 3, the second device also receives cell information from the first device. That is, in the network residence method shown in fig. 3, the description is given taking an example in which the cell information is transmitted by the first device. As shown in fig. 3, the network residence method may include, but is not limited to, the following steps:

S301, the first device determines cell information, wherein the cell information comprises cell identifications of cells obtained by sequencing the signal strengths of the cells from strong to weak.

In an alternative embodiment, the first device determines the cell information in the following manner: if the connected second equipment is detected, periodically searching each cell in the current network environment; and determining the cell information according to the searched cells.

In this embodiment, the determining, by the first device, cell information according to each searched cell may include: sequencing the cell identifiers of the cells according to the sequence from strong to weak of the signal intensity of the cells to obtain the sequenced cell identifiers of the cells; and determining the cell information based on the cell identification of each cell after sequencing. Alternatively, the cell identities of the cells may be ordered in the order of strong to weak signal strengths of the cells, or in the order of reference signal received powers (reference signal receiving power, RSRP) of signals of the cells.

For example, suppose a first device detects that a second device has been connected, searching for 5 cells in the current network environment, such as cell 1, cell 2, cell 3, cell 4, and cell 5, for a first time. The first device orders the cell 1, the cell 2, the cell 3, the cell 4 and the cell 5 according to the sequence from strong to weak cell signal intensity, and the obtained cell identifiers are the cell 3, the cell 2, the cell 5, the cell 4 and the cell 1 in sequence. In this case, the first device may determine that the cell identities in the cell information are cell 3, cell 2, cell 5, cell 4, and cell 1 in that order.

In this embodiment, the first device may further re-search each cell in the current network environment if a change in the currently camping cell is detected.

Optionally, if the first device has preferentially registered the 5th generation mobile communication technology (5 th-GenerationMobile Communication Technology, 5G) cell and the second device only supports the 4G cell, the first device may search each 4G cell in the current network environment if detecting that the second device is connected; and determining 4G cell information according to each searched 4G cell.

S302, the first equipment sends the cell information to the second equipment, and correspondingly, the second equipment receives the cell information from the first equipment.

In an alternative embodiment, the first device may perform the step of transmitting cell information to the second device prior to responding to a first operation entered for the first device indicating confirmation of disconnection of the short-range wireless communication with the second device.

In this embodiment, the first operation is an operation acting on the first control; the first device also outputs a first control whether to disconnect the short-range wireless communication connection with the second device in response to a second operation input to the first device; a first operation is received for a first device entered through a first control.

Taking a short-range wireless communication connection as an example of a bluetooth connection, the step of the first device performing a transmission of cell information to the second device before responding to a first operation input for the first device is illustrated in connection with fig. 4a and 4 b.

Referring to fig. 4a, fig. 4a is a schematic diagram of a user interface according to an embodiment of the present application. As shown in fig. 4a, a schematic diagram of a default user interface provided by the setup application after the first device 401 starts the setup application. As shown in fig. 4a, the user interface may include: flight mode, wiFi, bluetooth, personal hot spot, mobile network, etc. The first device 401 may detect a touch operation by a user on different function options in the user interface, in response to which the first device 401 may switch on or off the functions of the flight mode, wiFi, bluetooth, personal hot spot, mobile network, etc.

As shown in fig. 4a, the user may enter an operation for disconnecting the bluetooth connection of the first device 401 from the second device by clicking on the second control 402.

Referring to fig. 4b, fig. 4b is a schematic diagram of another user interface according to an embodiment of the present application. As shown in fig. 4b, the first control 403 is a control that is output by the first device 401 in response to detecting a touch operation performed by the user on the second control 402 in fig. 4 a. In this case, the first device 401 may transmit cell information to the second device.

In another alternative embodiment, the first device may also determine whether the signal strength of the communication with the second device reaches a first threshold; if it is determined that the signal strength of the communication with the second device reaches a first threshold, a step of transmitting cell information to the second device is performed.

Optionally, the signal strength refers to a received signal strength indication (received signal strength indicator, RSSI). RSSI reflects the degree of attenuation of a signal, which is related to the received signal power, and is typically negative. Alternatively, the first device may employ the following equation (1) in determining the signal strength of the communication with the second device based on the received signal power.

RSSI＝10logP (1)

In equation (1), RSSI represents the signal strength of the communication between the first device and the second device; p represents the signal power received by the first device.

Taking the example of a short-range wireless communication connection between the first device and the second device being a bluetooth connection, assuming a first threshold of-70 decibel milliwatts (decibelrelativeto onemilliwatt, dbm), if the first device determines that the signal strength RRSI of the bluetooth communication with the second device reaches the first threshold (-70 dbm), then cell information may be sent to the second device.

S303, the second device detects whether the short-range wireless communication connection with the first device is disconnected.

And S304, if the second equipment detects that the short-distance wireless communication connection with the first equipment is disconnected, the second equipment performs cell registration based on the cell information.

In an alternative embodiment, the specific descriptions of steps S303 and S304 may be referred to the descriptions of steps S201 and S202, respectively, and will not be repeated here.

In the embodiment of the present application, when the first device is connected to the second device, the first device may determine cell information, where the cell information includes cell identifiers of cells obtained by ordering according to a sequence from strong to weak signal strengths of the cells; the first equipment sends cell information to the second equipment, and correspondingly, the second equipment receives the cell information from the first equipment; the second device performs cell registration based on the cell information in a case where disconnection of the short-range wireless communication with the first device is detected. It can be seen that the second device can quickly select a cell with better signal strength for registration based on the cell information from the first device when detecting that the short-range wireless communication connection with the first device has been disconnected. Therefore, the time for the second equipment to register the cell can be saved, and the second equipment can register the cell with better signal under the condition that the signal of the cell on the history frequency point is weak and the signal of the cell on the non-history frequency point is strong. In addition, the second device does not need to conduct cell search, so that power consumption caused by cell search can be reduced.

Referring to fig. 5, fig. 5 is a flow chart of another network residence method according to an embodiment of the present application. The difference from the network residence method shown in fig. 3 is that in the network residence method shown in fig. 5, it is also explained how the second device performs cell registration if all cells in the selected cell information attempt registration and all registration fails. As shown in fig. 5, the network residence method may include, but is not limited to, the following steps:
