Background

With the development of the fifth generation communication technology (5 th-generation, 5G) technology, the data transmission efficiency is higher and higher, so that the transmission of Extended real (XR) data with larger data volume by using the 5G network becomes possible.

In the related art, in order to save power consumption of the terminal device, the 5G network may transmit XR data in a discontinuous reception mode (Discontinuous Reception, DRX). However, in the transmission process of XR data from the XR server to the base station, the transmission time required for the XR data to reach the base station is unstable due to unstable transmission delay of the network. That is, for the base station, the period of packet arrival of XR data is fluctuating, i.e., jitter (jitter) exists. The existence of jitter brings a certain difficulty to the base station for configuring the DRX, if the base station determines the arrival time of XR data in advance and configures the DRX according to the arrival time, the base station can send a Wake-Up Signal (WUS) to the terminal equipment on a pre-configured transmission resource according to the arrival time, so that the terminal equipment starts to receive the XR data according to the WUS, and the terminal equipment can achieve the purpose of energy saving.

In the above technology, the service server may send XR data to the base station at a possible arrival time, but this requires that the service server and the base station maintain a common clock, and multiple service servers communicating with the base station all use different clocks, so that the base station needs to maintain the same clock as each service server, which has too high requirement on the base station, and makes clock maintenance work more complicated.

The IoT network may include, for example, an internet of vehicles. The communication modes in the internet of vehicles system are generally called as Vehicle to other devices (V2X, X may represent anything), for example, the V2X may include: vehicle-to-vehicle (Vehicle to Vehicle, V2V) communication, vehicle-to-infrastructure (Vehicle to Infrastructure, V2I) communication, vehicle-to-pedestrian communication (Vehicle to Pedestrian, V2P) or vehicle-to-network (Vehicle to Network, V2N) communication, etc.

Currently, XR data is mainly downlink video, and packets corresponding to video services have periodicity, for example, 60 video frames per second, and a video encoder generates a corresponding packet of one video frame every 16.67ms, and typically, one video frame is divided into tens to hundreds of IP packets due to the maximum packet limit of an internet protocol (Internet Protocol, IP) network. In a 5G network, one data (burst) is reached every 16.67ms, one burst containing a plurality of IP packets.

The terminal equipment of XR data receives the downlink video service and displays the downlink video service to the user, and meanwhile, information such as actions and positions of the user is collected and control information of the user is transmitted to the XR server, so that the power consumption of the terminal equipment is high. In addition, XR terminal devices are usually wearable devices, and cannot carry a large-capacity battery, so the power saving requirement of the XR terminal device is urgent.

In order to save power consumption of the terminal device, the 5G network may employ DRX to transmit XR data. As shown in fig. 1, the essence of using DRX to transmit XR data is that the network device configures a portion of time period a in advance for transmitting data, and a portion of time period B does not transmit data, so that the terminal device may only turn on the receiver during time period a, receive data and downlink control information, and turn off the receiver during time period B, so as to achieve the power saving effect. In order to reduce the waiting time of the downlink video service in the network device, when the network device configures DRX, the starting position of the time period a is generally determined according to the arrival time of the XR data.

However, after the XR data is sent out from the XR server, the XR data needs to be transmitted to a gateway of the 5G network through the IP network and further transmitted to the base station, and the transmission time required for the XR data to reach the network equipment is unstable due to unstable transmission delay of the IP network. I.e. for network devices the period of packet arrival of XR data is fluctuating, i.e. jitter is present.

That is, from the perspective of the network device, the period of arrival of each video frame is not always 16.67ms, but there is one jitter. Currently, typical jitter ranges determined by 3GPP are plus or minus 4ms.

While the presence of jitter brings a certain difficulty to configuring DRX for the base station, taking fig. 2 as an example, assuming that there is no jitter, the moment when XR data arrives at the network device is T1, the network device adopts DRX configuration 1 in fig. 2, that is, from the moment T1, both the network device and the terminal device consider to enter state a, and the terminal device turns on the receiver to receive the XR data.

However, in view of jitter, the earliest time that XR data arrives at the network device is T2 and the latest time is T3. If the network device determines the arrival time of the real XR data, DRX configuration 2 or DRX configuration 3 can be adopted, so that a better power saving effect is achieved. But the network device cannot determine whether jitter occurs, and cannot determine which DRX configuration to use when XR data actually arrives. If DRX configuration 2 in fig. 2 is adopted, additional power consumption of the terminal device is caused, and if DRX configuration 1 or DRX configuration 3 in fig. 2 is adopted, XR data may need to wait for a period of time after reaching the network device to be transmitted through the wireless interface, which causes additional data transmission delay.

If the network device determines the arrival time of the XR data in advance and configures the DRX according to the arrival time, the network device can send WUS to the terminal device on a pre-configured sending resource according to the arrival time, so that the terminal device starts to receive the XR data according to the WUS, and the terminal device can achieve the purpose of energy saving. At present, the service server can send XR data to the network device at a possible arrival time, but the service server and the network device maintain a common clock, and a plurality of service servers communicating with the base station all adopt different clocks, so that the network device needs to maintain the same clock with each service server, which has too high requirement on the network device, and the clock maintenance work is complicated.

In the related art, WUS signals may also be employed to solve the above-described problems.

Specifically, the network device may pre-configure dense radio resources, and after receiving the XR data, the network device may transmit the WUS signal to the terminal in a special transmission manner, and start to transmit the XR data, where the terminal device only needs to consume a small amount of electric power to receive the WUS signal. After receiving the WUS signal, the terminal device starts the receiver to receive the XR data.

Fig. 3 is a schematic diagram illustrating an exemplary radio resource for transmitting WUS, hereinafter referred to as WUS resource.

As shown in fig. 3, the small squares represent preconfigured WU resources, the open squares represent WUs resources not used to transmit WUs signals, the solid squares represent WUs resources used to transmit WUs signals, the dashed lines represent the time when XR data arrives at the network device without jitter, and the dashed boxes represent the time period when XR data actually arrives at the network device. It can be seen that the first burst arrives on time, the second burst arrives in advance, the third burst arrives in delay, the network device sends a WUS signal before the number of air interface transmissions, and the terminal device opens the receiver after receiving the WUS signal, and enters the receiving state.

Since the interval of the video frames of the XR data is 16.67ms at present, and the typical jitter range determined by the 3GPP is positive and negative 4ms, only the WUS resources need to be configured in half of the time period, as shown in fig. 4, when there is no jitter, the arrival time of two bursts are respectively T1 and T1', and when there is jitter, the possible arrival time of two bursts are respectively T2 to T3, T2' to T3', wherein the time period length of T2 to T3 is 8ms.

It follows that the overhead of WUS resources is large in the presence of jitter.

Therefore, the application provides a service communication method, the service server sends the arrival time of the service data to the terminal equipment, and the terminal equipment sends the arrival time to the network equipment, so that the network equipment can determine the WUS resource according to the arrival time. The network device can determine the arrival time of the service data without maintaining the same clock with each service server, thereby reducing the clock maintenance workload, and the network device can determine the possible arrival time of the service data to the network device in advance under the condition of jitter, and reducing the expenditure of the network device for WUS resources.

For easy understanding, an application scenario to which the embodiment of the present application is applied is described below with reference to an example of fig. 5.

Fig. 5 is a schematic diagram of an application scenario to which the present application is applicable. Referring to fig. 5, the network device 501, the service server 502 and the terminal device 503 are included, and communication is performed between the network device 501, the service server 502 and the terminal device 503 through the internet.

The service server 502 may transmit information such as arrival time of service data to the terminal device 503, and the terminal device 503 transmits the information to the network device 501, so that the network device 501 may determine WUS resources according to the arrival time and the like, to transmit WUS signals to the terminal device 501, so that the terminal device 501 turns on a receiver to start receiving service data.

It is understood that the number of network devices 501, service servers 502 and terminal devices 503 may be plural, which are not shown in the figure.

In the embodiment of the application, the network device can be any device with a wireless receiving and transmitting function. The apparatus includes, but is not limited to: an Evolved Node B (eNB), a radio network controller (Radio Network Controller, RNC), a Node B (Node B, NB), a base station controller (Base Station Controller, BSC), a base transceiver station (Base Transceiver Station, BTS), a Home base station (e.g., home Evolved NodeB, or Home Node B, HNB), a Base Band Unit (BBU), an Access Point (AP) in a wireless fidelity (WIRELESS FIDELITY, WIFI) system, a radio relay Node, a radio backhaul Node, a transmission Point (Transmission Point, TP), or a transmission reception Point (Transmission and Reception Point, TRP), etc., may also be 5G, such as NR, a next generation base station (The Next Generation Node B, gNB) in the system, or a transmission Point (TRP or TP), one or a group of antenna panels (including multiple antenna panels) of a base station in the 5G system, or may also be a network Node constituting the gNB or the transmission Point, such as a Baseband Unit (BBU), or a Distributed Unit (DU), etc.

In some deployments, the gNB may include a Centralized Unit (CU) and DUs. The gNB may also include an active antenna Unit (ACTIVE ANTENNA Unit, AAU). The CU implements part of the functionality of the gNB and the DU implements part of the functionality of the gNB. For example, the CU is responsible for handling non-real-time protocols and services, implementing the functions of radio resource control (Radio Resource Control, RRC), PDCP layer. The DU is responsible for handling Physical layer protocols and real-time services, and implements functions of a radio link control (Radio Link Control, RLC) layer, a MAC layer, and a Physical (PHY) layer. The AAU realizes part of physical layer processing function, radio frequency processing and related functions of the active antenna. Since the information of the RRC layer may be eventually changed into or converted from the information of the PHY layer, under this architecture, higher layer signaling, such as RRC layer signaling, may also be considered to be transmitted by the DU or by the du+aau. It is understood that the network device may be a device comprising one or more of a CU node, a DU node, an AAU node. In addition, the CU may be divided into Network devices in an access Network (Radio Access Network, RAN), or may be divided into Network devices in a Core Network (CN), which the present application is not limited to.

The network device provides services for the cell, and the terminal device communicates with the cell through transmission resources (e.g., frequency domain resources, or spectrum resources) allocated by the network device, where the cell may belong to a macro base station (e.g., macro eNB or macro gNB, etc.), or may belong to a base station corresponding to a small cell (SMALL CELL), where the small cell may include: urban cells (Metro cells), micro cells (Micro cells), pico cells (Pico cells), femto cells (Femto cells) and the like, and the small cells have the characteristics of small coverage area and low transmitting power and are suitable for providing high-rate data transmission services.

The wearable device can also be called as a wearable intelligent device, and is a generic name for intelligently designing daily wearing and developing wearable devices by applying a wearable technology, such as glasses, gloves, watches, clothes, shoes and the like. The wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user.

The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments. The following specific embodiments may exist alone or in combination with one another, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 6 is a flow chart of a service communication method according to an embodiment of the present application, and referring to fig. 6, the method includes the following steps.

S601, the terminal equipment acquires transmission time information of service data, wherein the transmission time information comprises arrival time of the service data to the network equipment.

Before acquiring service data, the terminal device may acquire transmission time information of the service data.

For example, in one possible implementation manner, the transmission time information of the service data may be sent by the service server corresponding to the service data to the terminal device, and specifically, the service server may send the transmission time information of the service data to the terminal device through an application layer message or the like.

Alternatively, the transmission time information may further include time offset information (jitter information) of the service data, transmission period, and the like, and then the terminal device may transmit these information to the network device.

It should be noted that, the arrival time of the service data to the network device may be the arrival time of the first burst or the arrival time of the nth burst, which is not limited in the present application. The arrival time of the first burst or the nth burst can be represented by a specific clock, and then the terminal equipment and the service server maintain the same clock.

S602, the terminal equipment sends the arrival time to the network equipment.

After the terminal device obtains the transmission time information of the service data, the terminal device can send the service data in the transmission time information to the network device to reach the arrival time of the network device.

Before sending the arrival time, the terminal device may generate a form that the network device can interpret from the arrival time.

In one possible implementation, the terminal device may represent the arrival time by a clock signal, obtain a first representation result for characterizing the arrival time, and then send the first representation result like the network device.

For example, when the terminal device and the network device maintain the same clock, such as a "5G clock", the terminal device may represent the arrival time by the 5G clock, forming a first representation of the arrival time for the 5G clock.

In another possible implementation manner, the terminal device may represent the arrival time by using a radio frame identifier, obtain a second representation result for characterizing the arrival time, and then send the second representation result to the network device.

For example, the radio frame identifier may be at least one of a system frame number SFN, a subframe number, a slot number, or an OFDM symbol, and the terminal device may indicate the arrival time by using the radio frame identifier, for example, indicate the arrival time as "sfn=365, subframe number=1, slot number=0, and OFDM symbol=3", where the second indication result is "sfn=365, subframe number=1, slot number=0, and OFDM symbol=3". So that the network device can read the arrival time according to the second representation result.

In the scenario where a network handover of a terminal device occurs, if the arrival time is represented using a clock signal and the target network device (e.g., target base station) also maintains the same clock, then during the handover the source network device (e.g., source base station) may occur the arrival time to the target network device without the terminal device having to send the arrival time to the target network device.

Or in the scenario that the terminal device performs cell handover, taking the 5G clock as an example, the terminal device may determine whether the target network device maintains the 5G clock, and when determining that the target network device maintains the 5G clock, the terminal device may represent the arrival time with the 5G clock and send the arrival time to the target network device. When the target network device does not maintain the 5G clock, the terminal device may represent the arrival time in the form of a radio frame identifier or the like, and then send the arrival time to the target network device.

In the scenario where the terminal device performs cell reselection, the terminal device may send the arrival time to the target network device, and the specific implementation may refer to the description in the above network handover scenario, which is not described herein again.

The terminal device can send the arrival time or transmission time information to the network device through the formats of RRC message, PDCP control signaling, RLC control signaling, MAC layer control signaling, MAC CE and the like, and the application does not limit the mode of sending the arrival time or transmission time information to the network device by the terminal device.

And S603, the network equipment acquires the arrival time and determines whether a further processing mode is adopted according to the arrival time.

Alternatively, the network device may be an arrival time of the service data sent by the receiving terminal device to arrive at the network device.

The network device may also receive time offset information and a transmission period of service data sent by the terminal device.

Or the network device may also receive time deviation information and transmission period of the service data sent by the service server corresponding to the service data, and specifically, the service server may send the time deviation information and transmission period of the service data to the network device through a "service server-XR service function module-SMF-AMF-network device" path.

Optionally, the further processing manner may be that the network device may determine a radio resource period for transmitting WUS according to the arrival time.

S604, if the further processing mode is determined to be adopted, the network equipment sends a notification message to the terminal equipment, wherein the notification message is used for indicating the terminal equipment to perform corresponding processing.

Optionally, when it is determined that the further processing manner is adopted, the network device may send a notification message to the terminal device according to the radio resource time period for sending WUS, where, by way of example, the notification message may include a WUS signal, which is used to instruct the terminal device to turn on the receiver, and start receiving service data.

In one possible implementation manner, the network device may determine a radio resource time period for sending WUS according to time deviation information and arrival time of service data, that is, the network device determines a certain radio resource time period for sending WUS according to the arrival time and the time deviation information, without pre-configuring dense WUS resources, thereby saving WUS resources of the network device.

In another possible implementation manner, the network device may further determine resources in a radio resource time period corresponding to each data in the service data according to a transmission period of the service data, and when the network device acquires the service data, send WUS to the terminal device based on the resources in the radio resource time period corresponding to each data in the service data, so that the terminal device starts to receive the service data sent by the network device.

In this embodiment, the terminal device may acquire transmission time information of service data, where the transmission data information includes arrival time of the service data at the network device, and then send the arrival time to the network device. After the network device obtains the arrival time of the service data sent by the terminal device to the network device, the network device can determine whether to adopt a further processing mode according to the arrival time, if the network device determines to adopt the further processing mode, the network device sends a notification message to the terminal device, wherein the notification message is used for instructing the terminal device to perform corresponding processing, for example, the network device determines a wireless resource time period for sending WUS to the terminal device according to the arrival time, so that the same clock is not required to be maintained between the network device and each service server, the clock maintenance workload is reduced, and the network device can determine the possible time when the service data arrives at the network device in advance under the condition of jitter, so as to reduce the resource overhead of the network device for WUS.

Next, another service communication method will be described by way of embodiment two.

Fig. 7 is a flow chart of another service communication method according to the second embodiment of the present application, and referring to fig. 7, the method includes the following steps.

S701, the terminal equipment receives the Nth data of the service data sent by the service server, wherein the Nth data comprises a plurality of data packets.

The terminal device may receive the nth data of the service data sent by the service server, where N is an integer greater than or equal to 1, and the terminal device may determine the arrival time for the subsequent data.

S702, the terminal equipment analyzes the Nth data to obtain transmission time information of other data after the Nth data.

After receiving the nth data, the terminal device may parse the nth data to obtain transmission time information of other data after the nth data, where the transmission time information may include application time of the nth data, and when the service data is video data, the application time of the nth data may be referred to as playing time.

S703, the terminal device sends the application time of the Nth data to the network device.

After the terminal device determines the application time of the nth data of the service data, the application time may be generated to the network device.

In one possible implementation, if the terminal device and the network device maintain the same clock, the terminal device may represent the application time by a clock signal, e.g. a 5G clock, the terminal device may represent the application time by a 5G clock, and then send the corresponding representation result to the network device.

In another possible implementation, if the terminal device and the network device do not maintain the same clock, the terminal device may indicate the application time by using a radio frame identifier, and then send the corresponding indication result to the network device, where the radio frame identifier may be at least one of a system frame number SFN, a subframe number, a slot number, or an OFDM symbol, for example.

And S704, the network equipment determines the time corresponding to the preset time before the application time as the arrival time of other data after the Nth data of the service data.

After the network device receives the application time of the nth data sent by the terminal device, the time corresponding to the preset duration before the application time can be determined as the arrival time of other data after the nth data.

The preset duration is indicated by an application layer, a service server, or a network management platform of the terminal device, which is not limited in the present application.

And S705, the network equipment determines whether to adopt a further processing mode according to the arrival time of other data after the Nth data.

Optionally, the further processing manner may be, for example: the network device may determine a radio resource time period for transmitting WUS to the terminal device according to an arrival time of other data after the nth data, so that a WUS signal may be transmitted to the terminal device according to the resource, and the terminal device may be in a receiving state according to the signal to receive other data after the nth data.

In one possible implementation manner, the network device may determine a radio resource time period according to the arrival time and the time deviation information of the service data, that is, the network device determines a certain radio resource time period for sending WUS according to the arrival time and the time deviation information, without configuring dense WUS resources in advance, thereby saving WUS resources of the network device.

In another possible implementation manner, the network device may further determine resources in a radio resource time period corresponding to each data in the service data according to a transmission period of the service data, and when the network device acquires the service data, may send WUS to the terminal device based on the resources in the radio resource time period corresponding to each data in the service data.

S706, if the further processing mode is determined to be adopted, the network equipment sends a notification message to the terminal equipment, wherein the notification message is used for indicating the terminal equipment to perform corresponding processing.

Alternatively, the network device may send a notification message to the terminal device according to the radio resource time period for sending WUS, where the notification message may include a WUS signal, for example, to instruct the terminal device to turn on the receiver and start receiving service data.

Specifically, the network device may determine, according to a transmission period of service data, resources corresponding to each of other data after the nth data in the radio resource period, and when the network device acquires the other data after the nth data, that is, the n+1st data, the n+2nd data, and the like, the network device may send, to the terminal device, a notification message based on the resources corresponding to the data, where the notification message may include a WUS signal, so that the terminal device may start to receive the data according to turning on the receiver.

In this embodiment, the terminal device receives the nth data of the service data sent by the service server, where the nth data includes a plurality of data packets, then the terminal device may parse the nth data to obtain transmission time information of other data after the nth data, and the terminal device sends the application time of the nth data to the network device, so that the network device determines a time corresponding to a preset time before the application time, as an arrival time of the other data after the nth data of the service data, and the network device may determine whether to use a further processing manner according to the arrival time, if it determines to use the further processing manner, the network device sends a notification message to the terminal device, where the notification message is used to instruct the terminal device to perform corresponding processing, for example, the network device may determine a radio resource time period for sending WUS to the terminal device according to the arrival time of the other data after the nth data, so that the network device and each service server do not need to maintain the same clock, thereby reducing the clock maintenance workload, and enabling the network device to determine in advance a possible time when there is jitter, when the service data arrives at the network device, so as to reduce the network device cost of using WUS.
