Detailed Description

For ease of understanding, some terms referred to in the embodiments of the present application are described below:

vehicle networking (vehicle-to-advertising, V2X): communication between a vehicle-to-vehicle (V2V), a vehicle-to-infrastructure (V2I), a vehicle-to-network (V2N), and a vehicle-to-pedestrian (V2P) can be realized by providing vehicle information through sensors or vehicle-mounted terminal devices, etc., which are mounted on the vehicle. Therefore, the terminal devices involved in the internet of vehicles may be referred to as V2X terminal devices.

Side Link (SL): link for direct communication between V2X terminal devices. V2X terminal devices may communicate with each other over short distances via a sidelink interface, which may also be referred to as a proximity communication 5 (PC 5) interface, or a direct link interface.

The data processing method provided in this embodiment of the present application may be applied to various communication networks, for example, may be applied to a 5G communication network, a 3G communication network, or a 4G communication network, and may also be applied to a future communication network, for example, a 6G network, a 7G network, and the like, and names of the above-mentioned network elements are not limited, and may be replaced by names of network elements having the same or similar functions in the future communication network, which is not limited in this application.

The data processing method provided by the present application can be specifically applied to a V2X communication system, which can be based on various communication networks described above.

The V2X communication system may specifically include, but is not limited to: a Unified Data Management (UDM) network element, a Policy and Control Function (PCF) entity, a network capability opening function (NEF) entity, an Application Function (AF) entity, a Unified Data Repository (UDR) network element, an Access Management Function (AMF) entity, a Session Management Function (SMF) entity, a User Plane Function (UPF) entity, a Radio Access Network (RAN) device, a network data analysis function (nwd data analysis function, nwd AF) entity (not shown), a data analysis entity, and the like. And the number of the respective network elements or devices may be one or more.

The AMF entity is mainly responsible for functions of authentication of the terminal equipment, mobility management of the terminal equipment, network slice selection, selection of a session management functional entity and the like. In the embodiment of the present application, the AMF entity may forward data sent or received by the PCF entity, and details are not described in the following embodiments of the present application.

The PCF entity is mainly responsible for providing the policy rules to the network entity. The method comprises the steps of providing a uniform strategy framework to control network behaviors or providing strategy rules to a control layer network function, and simultaneously, acquiring user subscription information related to strategy decision. The policy and rule management system is used for managing network behaviors, providing policies and rules for a control plane, and generally making policy decisions according to subscription information and the like.

The RAN may be a network composed of a plurality of RAN devices, and implements functions of a radio physical layer, resource scheduling and radio resource management, radio access control, mobility management, and the like. The RAN equipment is connected to the UPF entity via the user plane interface N3 for transmitting data of the terminal equipment. The RAN device establishes a control plane signaling connection with the AMF entity through the control plane interface N2, so as to implement functions such as radio access bearer control. In the present application, fig. 1 shows a radio access network device, that is, a RAN device, which may also be replaced by a wired access network device, and fig. 1 illustrates only the RAN device by way of example, and in the following description of the present application, the RAN device is directly referred to as an access network device, that is, the RAN device and the wired access network device are included. Specifically, the access network device may be a device having a central control function, such as a macro base station, a micro base station, a hotspot (pico), a home base station (femeto), a Transmission Point (TP), a relay (relay), an Access Point (AP), and the like. If the access network device is a base station, the base station may be a base station (eNodeB, eNB) in Long Term Evolution (LTE), a base station (gbnodeb, gNB) in New Radio (NR), or the like.

User Equipment (UE) for providing voice/data connectivity to a user, such as a handheld device or a vehicle-mounted device with wireless connectivity capability. And may also include smart mobile phones, Mobile Stations (MSs), Mobile Terminals (MTs), and the like, which may also be referred to as terminal devices hereinafter.

The UPF entity, as an anchor point of a Protocol Data Unit (PDU) session connection, is responsible for filtering data packets, transmitting/forwarding data, controlling rate, generating charging information, and the like of the user equipment.

And the UDM network element mainly manages and controls user data. For example, the management of the subscription information may include: obtain subscription information from UDR network elements and provide to other network elements (e.g., AMF entities), generate 3GPP authentication credentials for the terminal device, and register to maintain the network elements currently serving the terminal device.

And the UDR network element is mainly used for storing user data. The user data may include subscription data invoked by the UDM network element, policy information invoked by the PCF entity, structured data for capability openness, application data invoked by the NEF entity.

The NEF entity is used for connecting other internal network elements of the core network with an external application server of the core network, providing services such as authentication, data forwarding and the like when the external application server initiates a service request to the core network, and providing network capacity information to the external application server or providing information of the external application server to the network elements of the core network. In the embodiment of the present application, when the AF entity performs data transmission with a core network element or an access network device, for example, a PCF entity, an access network device, a data analysis entity, an NWDAF entity, or the like, the NEF entity may forward the data. Specifically, when the AF entity sends data to a core network element or an access network device, the NEF entity may perform security authentication on the data (the NEF authenticates an AF identifier carried by an AF sending message, and confirms that the AF is an AF trusted by an operator), identifier conversion (the AF sending message may carry an external identifier, such as a served user identifier or an operation identifier of the message, and the NEF needs to convert the external identifier into an internal identifier identified by the core network element), and so on, so that the core network element or the access network device may safely and correctly receive the data sent by the AF entity. The AF permitted by the operator can directly send the message to the PCF entity through the NEF or store the message in the UDR or UDM network element through the NEF, then the PCF entity reads or receives the message in the UDR or UDM network element, and the mode adopted by the core network element to acquire the AF message is determined by the operator in actual deployment. When the AF needs to send messages to the access network device or to the UE through the core network element, the PCF entity needs to send the messages to the access network device through the AMF entity or the PCF entity sends the messages to the UE through the AMF entity and the access network device. The specific steps are not described in detail in the following embodiments of the present application.

The SMF entity is mainly responsible for control plane functions of UE session management, including UPF selection, IP address allocation, QoS management of the session, and obtains Policy Control and Charging (PCC) policies (from the PCF entity).

And the AF entity is specifically an application server corresponding to the application. The method has the application service function, and interacts with the network element of the core network to provide service for the terminal equipment. For example, the PCF entity interacts to perform service policy control, or interacts to obtain network capability information or provide application information to the network, or interacts to provide data network access point information to the PCF entity for the PCF entity to generate corresponding routing information of the data service.

And the NWDAF entity is used for analyzing and predicting the data of the network element of the core network.

And the data analysis entity can be used for carrying out data analysis and prediction on the information of the base station. The data analysis entity may be specifically deployed in the access network device, or may be an independent device deployed on the access network side. In this application, the data analysis entity may implement a part of functions of the access network device, and the data analysis entity may also implement a part of functions of the NWDAF entity.

In addition, in addition to the Network elements included in fig. 1, the V2X communication system may further include other Network elements (not shown in the figure), for example, an Authentication Server Function (AUSF), a Network Slice Selection Function (NSSF), and the like.

Illustratively, taking the access network device as a base station as an example, a specific application scenario is described. For example, in a V2X communication scenario, the UE communicates with the SL via the PC5 interface, and the SL carries important services, such as security services, sensor sharing services for autonomous driving, and the like. And different from Uu port communication, the base station may directly acquire conditions of network resources of the UE in its coverage area, for example, channel quality, congestion condition, and the like. In the PC5 interface communication between the UE and the UE, the base station cannot directly acquire the communication quality of the PC5 interface of the UE in its coverage, for example, channel quality parameters, congestion information, and the like. Estimating the performance of the network according to the channel quality reported by the current UE can only judge the network condition of the current position of the UE. After the UE reports the SL network information, the SL network information at the location of the UE changes with the movement of the location of the UE, and the base station cannot accurately allocate or adjust the network resources used by the UE according to the SL network information reported by the UE. Therefore, the embodiments of the present application provide a data processing method, which can more accurately adjust network resources for SL communication of a UE.

The following describes a data processing method provided in the present application based on the network architecture of fig. 1.

Referring to fig. 2, an embodiment of the present application provides a data processing method, which is described in detail as follows.

201. The access network equipment acquires the information of N grids in a preset range.

The preset range may be a range set based on a cell, a sector, or a base station, or a range set based on a map. For example, the preset range is a road area in a map, or, when the access network device is one or more base stations, the preset range is one or more cells under the one or more base stations, or, when the access network device is one or more base stations, the preset range is all or part of sectors under the one or more base stations. Wherein, a cell under the base station can be divided into one or more sectors.

The N grids may be obtained by dividing the preset range, and N is a positive integer greater than or equal to 1. The partitioning of the grid may take a variety of granularities. For example, the coverage of the cell with the granularity as the minimum coverage in the preset range is divided, so that the coverage of each grid is smaller than the minimum coverage. For another example, the coverage area of the minimum sector of the base station within the preset range is divided by granularity, so that the coverage area of each grid is smaller than the coverage area of the minimum sector.

Wherein, the information of the N grids may include: identification of each of the N grids and coverage information. The coverage area of each grid in the N grids may be the same or different.

Wherein, the coverage information of each grid may include: the length and width of each of the grids, or the length, width and elevation of each of the grids. The identification of a grid may be used to uniquely identify a grid, e.g., the name of the grid. It should be noted that there are many cases in the coverage area of each of the N grids, for example, the size of the coverage area of each grid may be a preset value, that is, the size of the coverage area of each grid is the same. The coverage area size of each grid may also be different, or the coverage area size of some grids in the N grids may also be the same.

In general, the coverage of each grid can be divided into smaller areas. For example, the coverage size of each grid is smaller than the coverage size of the smallest cell under the base station, or the coverage size of each grid is smaller than the average coverage size of a plurality of cells under the base station, or the coverage size of each grid is smaller than the coverage size of the smallest sector under the base station, and so on, so that when the network device analyzes the network resource subsequently, the analysis can be performed based on the grid granularity smaller than the cell granularity or smaller than the smallest sector granularity, and the accuracy of the analysis result of the network resource is improved.

The network device and the network devices in the following embodiments of the present application may be an NWDAF entity or a data analysis entity in fig. 1, which will not be described in detail in the following embodiments of the present application.

Step 201 may be implemented in various ways, as follows.

In a first way, the access network device may receive information of the N grids from other network elements.

The other network element may be a PCF entity, the above network device, or an AF entity, without limitation.

For example, the PCF entity divides the preset range to obtain N grids, and sends information of the N grids to the access network device, and the access network device receives the information of the N grids from the PCF entity.

For another example, the data analysis entity may divide the preset range to obtain N grids, and send information of the N grids to the access network device, and the access network device receives the information of the N grids from the data analysis entity.

For another example, the AF entity may divide the preset range to obtain N grids, and send information of the N grids to the access network device, and the access network device receives the information of the N grids from the AF entity.

And in the second mode, the access network equipment performs grid division on the preset range to obtain the information of N grids in the preset range.

In one example, the access network device obtains information of a map, and the preset range may be a partial area or a whole area in the map. The access network device may divide the preset range based on the information of the map to obtain N grids within the preset range, and allocate an identifier to each grid of the N grids to further obtain information of the N grids.

The information of the map may include information of a geographic location within the preset range, for example, roads, mountains, buildings, and the like within the preset range may be included in the map. The information of the map may be stored in the access network device, or may be sent to the access network device by another network element, for example, the information of the map may be sent to the access network device by an Application Server (AS) or a UDR network element.

The access network device divides the preset range based on the information of the map, and specifically may divide the preset range according to a preset size, for example, each grid has a length of 20 meters and a width of 15 meters.

In addition, if the second method is adopted, the method may further include: the access network device sends the information of the N grids to other network elements, such as PCF entity, NWDAF entity, AF entity, or data analysis entity, without limitation.

202. The access network equipment receives first SL network information from the UE.

Wherein the access network device may receive first SL network information from one or more UEs.

Specifically, the first SL network information may include at least one of: location information of the UE, channel quality information, V2X service information, or road information, etc.

The location information of the UE may include longitude, latitude, altitude, and the like of the location where the UE is located.

The channel quality information may include information characterizing communication quality of the UE currently performing SL communication, and specifically may include channel quality reference information, or Channel Busy Rate (CBR) information, and the like. The channel quality reference information may include: information for measuring channel quality corresponding to data transmission of the V2X service via the PC5 interface, for example, a block error rate (BLER), a signal to interference plus noise ratio (SINR), and a received power.

The V2X service information may include information related to a V2X service currently performed by the UE, for example, a service type of the V2X service, a channel occupation amount for transmitting data of the V2X service, a packet priority of the V2X service, communication parameters of the V2X service, interface information corresponding to the V2X service, and the like. Specifically, the communication parameters of the V2X service may include: PC5 resource level of V2X service or PC5 quality of service identifier (PC5QoS identifier, PQI) of V2X service, etc.; the interface information corresponding to the V2X service may include: the type or identity of the communication interface used to transmit the data of the V2X service, etc.

The road information may include a condition of a road where the UE is currently located, for example, the road information includes a traffic flow density within a certain range around a location where the UE is located on the current road, a vehicle traveling speed, and the like. The certain range may be a range of 100 meters around the location of the UE on the road, with the location of the UE as the center. The road information may also include road condition information collected by a sensor or a camera on the UE, such as road image, temperature, humidity, visibility, and the like.

In an optional implementation manner, the first SL network information further includes time information, that is, a collection time of the first SL network information, so that the access network device determines whether the first SL network information is available or an available weight according to the collection time of the first SL network information. This time information may also be referred to as a time stamp hereinafter. For example, the access network device may obtain the collection time of the first SL network information according to the timestamp, and thus determine whether the first SL network information has expired according to the collection time. If the difference between the acquisition time of the first SL network information and the current time is greater than a preset time value, the first SL network information may be discarded.

It should be noted that the UE may periodically report the first SL network information, so that the access network device may acquire the SL network information of the UE in real time. Furthermore, the access network device may obtain, according to the first SL network information reported by the UE, information of the communication quality of the SL communication performed by the UE, so as to perform network resource adjustment or network resource allocation on the UE.

203. And the access network equipment sends the identification of the first grid and second SL network information related to the first grid to the network equipment according to the first SL network information.

The first grid is a grid where the UE is located, that is, the UE is located in the first grid. The N grids include the first grid, in other words, the first grid is one or more of the N grids.

Wherein the second SL network information related to the first grid may refer to information communicated with SLs related to the one or more grids. For example, the second SL network information may include: the identification of UEs within the first grid, channel quality information within the first grid coverage, V2X traffic information for one or more UEs within the first grid coverage, road information within the first grid coverage, etc. Wherein, the channel quality information, the V2X service information, the road information, etc. can all refer to the relevant description in step 202.

The first SL network information and the second SL network information may be the same or different.

When the first SL network information is the same as the second SL network information, step 203 may include: and taking the first SL network information as the second SL network information, and sending the identifier of the first grid and the second SL network information to the network equipment.

When the first SL network information is not the same as the second SL network information, step 203 may include: and the access network equipment obtains second SL network information according to the first SL network information and sends the identifier of the first grid and the second SL network information to the network equipment.

The access network device may obtain the second SL network information according to the first SL network information in two ways.

In the first mode, the access network device preprocesses the first SL network information to obtain second SL network information.

For example, if the access network device receives a set of first SL network information, a part of data may be added, deleted, or modified in the set of first SL network information, so as to obtain second SL network information. If the access network device receives multiple sets of first SL network information, and if the multiple sets of first SL network information include information of different frequency bands (or channels), different roads, different positions, and the like, different information included in the multiple sets of first SL network information may be classified and combined (for example, the first SL network information of different frequency bands at the same position is classified and combined, or the first SL network information of different positions at the same frequency band is classified and combined, and the like). The access network device may further calculate parameters included in the plurality of first SL network information to obtain the second SL network information. For example, weighting or averaging may be performed on parameters, such as block error rate (BLER), signal to interference plus noise ratio (SINR), received power, and the like, included in the plurality of sets of first SL network information, to obtain an operated parameter, and then obtain second SL network information, where the second SL network information includes the operated parameter. In the embodiment of the application, the second SL network information can be obtained by preprocessing the first SL network information, so that the redundancy of the second SL network information sent to the network device by the access network device is reduced, and the efficiency of network resource analysis of the subsequent network device based on the second SL network information is improved.

And in the second mode, the access network equipment sends the first SL network information to the data analysis entity, and the data analysis entity preprocesses the first SL network information to obtain second SL network information and sends the second SL network information to the access network equipment.

In addition, in step 203, the access network device may determine that the UE is in the first grid according to the location of the UE and the information of the N grids. The location of the UE may be reported by the UE, for example, by reporting the first SL network information, or may be obtained by the access network device positioning the UE, or the access network device obtains the location from another network element, which is not limited.

In a specific implementation manner, the coverage of the first grid is smaller than the coverage of the current access cell of the UE, i.e. the granularity of the first grid is smaller than the granularity of the cell. The access network device sends SL network information of the first grid, for example, second SL network information, to the network device, so that the network device obtains a network resource analysis result based on the first grid. Because the first grid has smaller granularity than the cell, the accuracy of the network resource analysis result based on the first grid is higher, and the method shown in fig. 2 can greatly improve the accuracy of the network resource analysis result.

In the method provided by the embodiment of the present application, the access network device may obtain information of N grids within a preset range, and receive first SL network information from the UE. And then the access network equipment sends the identifier of the first grid and second SL network information related to the first grid to the network equipment according to the first SL network information, so that the network equipment analyzes network resources to obtain a network resource analysis result. The access network equipment provides the SL network information based on the grid granularity, so that the network equipment can adjust the network resources of the UE in the grid coverage range more accurately according to the network resources based on the network resource analysis result of the grid granularity, and the UE can use the network resources which adapt to the communication quality change of the SL communication to carry out the SL communication, thereby improving the efficiency of the UE for carrying out the SL communication, reducing the time delay of the UE for carrying out the SL communication and avoiding the condition of channel congestion when the UE carries out the SL communication. Moreover, the granularity of the grid can be smaller than the granularity of a cell, the granularity of a sector and the like, so that the access network equipment can adjust the network resources of the UE based on the grid granularity according to the network resource analysis result of the grid granularity, the accuracy of adjusting the network resources of the UE is improved, and the network resources of the UE can be adjusted more accurately.

In a possible implementation manner, after the step 203, the method further includes: the access network device sends a first request to the network device.

The first request is used for requesting to obtain a network resource analysis result of at least one grid. And, the first request may carry information of the at least one grid. For example, the first request may carry information such as an identifier, a coverage area, and the like of the at least one grid.

Wherein the network resource analysis result of the at least one grid is an analysis result of the network resource of the at least one grid. The at least one grid may be located within the coverage area of the access network device.

In a possible implementation manner, the first request further carries the second SL network information in step 203.

In another possible implementation manner, in step 203, a specific manner for the access network device to send the second SL network information to the network device may be: the access network device sends a first request to the network device.

The first request is used for requesting to obtain a network resource analysis result of at least one grid. And, the first request carries the information of the at least one grid and the second SL network information in step 203.

In a possible implementation manner, after step 203, or after the access network device sends the first request to the network device, the method further includes:

the access network equipment receives a network resource analysis result of at least one grid in the N grids of the network equipment;

when the network resource analysis result meets a first preset condition, the access network equipment sends SL radio bearer configuration to the UE in the coverage range of the at least one grid; alternatively, the first and second electrodes may be,

and when the network resource analysis result meets a first preset condition, the access network equipment allocates network resources for the UE in the at least one grid range according to the network resource analysis result.

Wherein the network resource analysis result of the at least one grid may include: QoS levels supported by SL communications in the at least one grid, congestion levels of SL communications in the at least one grid, Key Performance Indicators (KPIs) or adjustment indication information that SL communications in the at least one grid meet, and the like.

Specifically, the QoS class may include a PC5 quality of service identifier (PC5QoS identifier, PQI). The PQI may be formed by combining multiple QoS parameters, such as delay, packet loss rate, priority, etc.

Wherein the congestion level of the SL communication in the at least one grid can be used to characterize the congestion condition of the SL communication in the at least one grid. The network device may determine the congestion level of SL communication in the at least one grid according to the number of UEs performing V2X service in the at least one grid or channel occupancy, etc. Still further, the network device may determine the congestion level of SL communication in the at least one trellis in conjunction with parameters related to channel quality, such as SINR, received power, BLER, and the like.

The QoS KPI may include: delay or packet loss rate, etc. In particular, the latency may include an average latency or a maximum latency supported by each of the at least one grid, and the like. The packet loss rate may include: a maximum packet loss rate or an average packet loss rate of data transmission within the at least one grid coverage area, and the like.

The adjustment indication information may be resource adjustment indication information, which is used to indicate that network resources used by the UE in the coverage area of the at least one grid are required to be adjusted when the UE performs SL communication.

The first preset condition may be: the parameter value in the network resource analysis result is within the first preset range, or the network resource analysis result includes the resource adjustment indication information, which is not limited. For example, if the network resource analysis result carries at least one QoS level supported by SL communication in the grid range, the first preset condition includes: the SL communication within the at least one grid coverage currently supports a QoS level lower than the QoS level of V2X traffic for UEs within the at least one grid coverage. For another example, the first preset condition includes: the network resource analysis result carries the resource adjustment indication information.

In the case that the access network device sends the SL radio bearer configuration to the UE in the at least one grid coverage area, the SL radio bearer configuration may include information of network resources available to the UE, for example, frequency information and time domain information of PC5 resources available to the UE, and interface information (for example, type or identity of an interface, etc.) supporting V2X service data transmission in PC5 resources available to the UE. Further, the UE may select an available network resource according to the information of the network resource available to the UE carried in the SL radio bearer configuration. It is understood that the access network device may send the SL radio bearer configuration to the UE in the at least one grid coverage area for informing the UE of which PC5 resources are available, and the UE may select available PC5 resources for SL communication according to the SL radio bearer configuration.

And under the condition that the access network equipment of the access network equipment allocates network resources to the UE in the at least one grid coverage range according to the network resource analysis result, the access network equipment can send the information of the network resources allocated to the UE in the at least one grid coverage range through a control channel. Specifically, the access network device may determine, from the network resources within the at least one grid coverage, the network resources corresponding to the communication parameters of the V2X service of the UE within the at least one grid coverage according to the QoS level supported by the SL communication, the congestion level of the SL communication, the QoS KPI satisfied by the SL communication, and the like carried in the network resource analysis result in the at least one grid coverage, and allocate the network resources to the UE within the at least one grid coverage.

Specifically, the information of the network resources allocated to the UE in the at least one grid coverage area may include: frequency band information, time domain information of network resources allocated by the access network device for the UE, and interface information (for example, a type or an identifier of an interface) supporting transmission of V2X service data. Further, the UE updates the current network resource configuration of the UE according to the received information of the network resources from the access network device, and then the UE performs SL communication using the network resources allocated by the access network device.

For example, when the access network device determines that channel congestion occurs in a certain frequency band according to a network resource result, the access network device may avoid the frequency band in which channel congestion occurs when allocating network resources to the UE, so as to avoid that the UE performs SL communication in the frequency band in which channel congestion occurs, reduce a time delay of the UE performing SL communication, and improve efficiency of the UE performing SL communication.

For another example, if the network resource analysis result carries the resource adjustment indication information, the access network device allocates, according to the network resource of each grid in the at least one grid, the network resource used for SL communication to the UE in the coverage of each grid, so that the network resource for SL communication by the UE in the coverage of each grid can be allocated by the access network device, thereby implementing that the access network device schedules the network resource for SL communication by the UE in the coverage of the grid based on the grid granularity, and avoiding channel congestion caused by the UE selecting the network resource by itself.

In another specific implementation manner, when the network device is an NWDAF entity and the data analysis entity is a device deployed independently from the access network device, step 201 or step 203 may also be performed by the data analysis entity, so as to reduce the workload of the access network device.

Referring to fig. 3, another data processing method is provided in the present embodiment, which is described in detail below.

301. The network equipment acquires the information of N grids within a preset range.

The information of the N grids within the preset range may refer to the related description in step 201, and is not described herein again.

Wherein step 301 may be implemented in a variety of ways, as described below.

The first method is as follows: the network device receives the information of the N grids from other network elements, which may be PCF entities, access network devices, or AF entities, without limitation.

For example, the PCF entity divides the preset range to obtain N grids, and sends information of the N grids to the network device, and the network device receives the information of the N grids from the PCF entity.

For another example, the access network device may divide the preset range to obtain N grids, and send information of the N grids to the network device, and then the network device receives the information of the N grids from the data analysis entity.

For another example, the AF entity may divide the preset range to obtain N grids, and send information of the N grids to the network device, and then the network device receives the information of the N grids from the AF entity.

The second method comprises the following steps: when the network device is a data analysis entity, the network device performs grid division on a preset range to obtain information of N grids in the preset range.

Specifically, the manner of the data analysis entity performing trellis division on the preset range may be similar to the manner in step 202, and the access network device therein may be replaced by the data analysis entity, which is not described herein again.

It should be noted that, if step 301 can be implemented in the second manner, after step 301, the method may further include: the data analysis entity sends the information of the N grids to other network elements, such as an access network device, a PCF entity, an NWDAF entity, or an AF entity, without limitation.

302. The network device receives an identification of a first grid from the access network device and second SL network information associated with the first grid.

Wherein the N grids described in step 301 include the first grid, which may be one or more of the N grids.

In a possible implementation manner, when the information of the N grids received by the network device comes from the access network device, the network device may receive the information of the N grids from the access network device, the identifier of the first grid, and the second SL network information at the same time through the same message. It can also be understood that the access network device may send the information of the N grids, the identity of the first grid, and the second SL network information to the network device through the same message. For example, the access network device may send a first message to the network device, where the first message carries the information of the N grids, the identifier of the first grid, and the second SL network information.

The second SL network information may specifically refer to the related description in step 203.

303. And the network equipment obtains the network resource analysis result of at least one grid in the N grids according to the information of the N grids, the second SL network information and the identifier of the first grid.

The network device may analyze the network resource of at least one grid of the N grids according to the information of the N grids, the second SL network information, and the identifier of the first grid, to obtain a network resource analysis result of the at least one grid.

Wherein the at least one grid comprises a first grid. For example, the at least one grid may include a first grid and a grid adjacent to the first grid.

Specifically, after obtaining the identifier of the first grid and the second SL network information, the network device may determine that the second SL network information is related to the first grid based on the identifier of the first grid. And then the network equipment obtains a network resource analysis result of at least one grid based on the second SL network information and through a preset algorithm.

The preset algorithm may be a kalman filter algorithm or a neural network algorithm. For example, when the preset algorithm is a neural network algorithm, one or more of the number of UEs in the first grid coverage included in the second SL network information, V2X service information executed by the UEs in the first grid coverage, channel quality information in the first grid coverage, road information in the first grid coverage, or the like is/are used as an input of the neural network algorithm, and a network resource analysis result of at least one grid is output.

The network resource analysis result can refer to the related description in step 203.

In the method provided by the embodiment of the present application, a network device receives information of N grids and second SL network information related to a first grid. Thus, the access network device may send the second SL network information to the network device based on the grid granularity, and the network device may obtain a network resource analysis result of at least one grid based on the grid granularity. Therefore, the network resource of the UE within the grid coverage can be accurately adjusted based on the network resource analysis result of the grid granularity, and further, the UE can perform SL communication using the adjusted network resource, thereby improving the efficiency of the UE performing SL communication and reducing the delay of the UE performing SL communication. And, the granularity of the grid in the embodiment of the present application is small, for example, the granularity of the grid may be smaller than the granularity of a cell, the granularity of a sector, etc., therefore, the network device can obtain the network resource analysis result based on the grid granularity according to the second SL network information based on the grid, the obtained network resource analysis result is more accurate, and further, when the network resource of the UE, the communication parameter of the V2X service or the QoS parameter of the V2X service, etc. are adjusted based on the network resource analysis result, according to the more accurate adjustment of the network resource of the UE, the communication parameter of the V2X service or the QoS parameter of the V2X service, the accuracy of adjusting the network resource of the UE, the communication parameter of the V2X service or the QoS parameter of the V2X service is improved, and the more accurate adjustment of the network resource of the UE, the communication parameter of the V2X service or the QoS parameter of the V2X service is realized.

In a possible implementation manner, when the network device is a data analysis entity, step 303 may include: and the data analysis entity preprocesses the second SL network information to obtain preprocessed SL network information. And then analyzing the network resources of at least one grid in the N grids based on the preprocessed SL network information, the information of the N grids and the identification of the first grid to obtain a network resource analysis result of the at least one grid.

The manner in which the data analysis entity preprocesses the second SL network information may refer to the manner in which the access network device preprocesses the first SL network information in step 203, which is not described herein again.

In a possible implementation manner, after step 303, the method further includes:

the network device sends the network resource analysis result of the at least one grid to other network elements, such as the access network device, the PCF entity, or the AF entity, without limitation.

In a possible implementation manner, before or after step 303, the method further includes: the network device receives a first request from the access network device, where the first request is used to request to obtain the network resource analysis result, and the first request carries information of the at least one grid, for example, an identifier of the at least one grid, coverage information, and the like. After step 303, or if the network device receives the first request after step 303, after the network device receives the first request, the network device further sends the network resource analysis result to the access network device. Therefore, in this embodiment of the present application, the access network device may request the network resource analysis result of the at least one grid from the network device according to a requirement, so that the access network device may adjust or allocate network resources to the UE in the coverage area of the at least one grid according to the network resource analysis result of the at least one grid.

In another possible implementation manner, before or after step 303, the method further includes: the network device further receives a second request from the AF entity, where the second request is used to request to obtain the network resource analysis result, and the second request carries information of the at least one grid, for example, an identifier of the at least one grid, coverage information, and the like. After step 303, or if the network device receives the second request after step 303, after the network device receives the first request, the network device further sends the network resource analysis result to the AF entity. In this embodiment, the AF entity may request the network resource analysis result of the at least one grid from the network device according to a requirement, so that the AF entity may adjust the QoS parameter of the partial V2X service of the UE within the coverage of the at least one grid according to the network resource analysis result of the at least one grid.

Referring to fig. 4, another data processing method is provided in the present embodiment, which is described in detail below.

401. The PCF entity performs grid division on the preset range to obtain the information of N grids in the preset range.

The PCF entity may perform trellis division on the preset range to obtain information of N grids, where the information of N grids may refer to the related description in step 201.

Specifically, the PCF entity may divide the preset range in the second mode of step 202 by referring to the access network device dividing the preset range to obtain the relevant descriptions of the information of the N grids, and replace the access network device with the PCF entity, which is not described herein again.

402. The PCF entity sends information for N grids.

Wherein, the PCF entity may send the information of the N grids to other network elements. The other network elements may include: AF entity, access network device or network device, etc., without limitation.

In the method provided by the embodiment of the present application, the PCF entity may perform trellis division on the preset range to obtain N grids, and send information of the N grids to other network elements, so that the other network elements can obtain a result of the trellis division. The network equipment can obtain a network resource analysis result of at least one grid based on the grid granularity, and further can accurately adjust the communication parameters of the V2X service of the UE based on the grid granularity, so that the UE can use the adjusted communication parameters of the VX service to perform the V2X service, the efficiency of performing the V2X service is improved, and the time delay of the V2X service is reduced.

In a possible implementation manner, after step 402, the method further includes: the PCF entity receives the network resource analysis result from at least one grid of the N grids of the network device, and the network resource analysis result may refer to the related description in step 203 above.

And, when the network resource analysis result satisfies a second preset condition, the PCF entity may send communication parameters of the V2X service to the UE within the at least one grid coverage, where the communication parameters of the V2X service may include at least one of QoS parameters, address information, or frequency band information of the V2X service.

Wherein the QoS parameters may include one or more of the following: a PC5 quality of service identity (PC5QoS identifier, PQI) for indicating the QoS requirements of the UE; PC5priority information (PC5priority level) indicating a transmission priority of the V2X service message; PC5 guaranteed stream bit rate (GFBR); PC5 maximum stream bit rate (MFBR); a packet error rate (packet error rate) indicating a probability of packet error that can be received, and the like. The QoS parameter may be generated by the PCF entity for the UE in the coverage area of the at least one grid, or the PCF entity may receive the QoS parameter from one or more AF entities, or the PCF entity may receive some of the QoS parameters from one or more AF entities. The address information may include information of an address that the UE may use when performing the V2X service, for example, the address information may include a specific address that one of the V2X services of the UE may access. The frequency band information is information of a frequency band that can be used by the UE when performing the V2X service.

In addition, when the network resource analysis result satisfies a second preset condition, the PCF entity may further send a control policy to the UE within the coverage of the at least one grid, where the control policy is used to adjust an interface used when the UE transmits data of the V2X service. For example, the control policy may be used to allocate the UE to transmit data of V2X traffic using the PC5 interface in the first frequency band, to transmit data of V2X traffic using the Uu port in the second frequency band, or the UE may transmit data of V2X traffic using the PC5 interface in the first time period, may transmit data of V2X traffic using the Uu port in the second time period, and so on.

The second preset condition may be: and the parameter value in the network resource analysis result is in a second preset range, or the network resource analysis result comprises adjustment indication information and the like.

Wherein the adjustment indication information may be communication parameter adjustment indication information of V2X traffic, and the communication parameter adjustment indication information of V2X traffic is used to indicate that the communication parameters of V2X traffic of the UE within the coverage of the at least one grid need to be adjusted.

The second preset condition may be the same as or different from the first preset condition in step 203.

Therefore, in the embodiment of the present application, the PCF entity may issue, according to a network resource analysis result of at least one grid from the network device, communication parameters of the V2X service to the UE in the coverage area of the at least one grid, so as to adjust the communication parameters of the V2X service of the UE in the coverage area of the at least one grid, or the PCF entity may issue, to the UE in the coverage area of the at least one grid, a control policy, so as to control an interface used when the UE in the coverage area of the at least one grid performs data transmission of the V2X service. Further, the UE may perform the V2X service according to the communication parameter or the control policy of the V2X service issued by the PCF entity, which may improve the efficiency of the data transmission of the V2X service performed by the UE, and reduce the time delay of the data transmission of the V2X service performed by the UE.

Referring to fig. 5, another data processing method is provided in the present embodiment, which is described in detail below.

501. And the AF entity performs grid division on the preset range to obtain the information of N grids in the preset range.

The AF entity may perform grid division on the preset range to obtain information of N grids, where the information of N grids may refer to the description in the above 201, and is not described again.

Specifically, the manner in which the AF entity divides the preset range may be similar to the manner in which the access network device divides the preset range in step 202 to obtain information of N grids, and the access network device may be replaced with the AF entity, which is not described herein again.

502. The AF entity sends information of N grids.

The AF entity may send the information of the N grids to other network elements, where the other network elements may include: access network equipment, NWDAF entity, PCF entity, etc., without limitation.

In this embodiment, the AF entity may perform trellis division on the preset range to obtain N grids, and send information of the N grids to other network elements, for example, a network device, an access network device, and the like. So that other network elements can learn the result of the grid division. And the network device may obtain a network resource analysis result of at least one grid based on the grid granularity, and may further implement adjusting the QoS parameter of the V2X service of the UE based on the grid granularity. Further, the UE may use the adjusted QoS parameter of the V2X service to perform the V2X service, improve the efficiency of the V2X service, and reduce the delay of the V2X service.

In one implementation manner, after step 502, or before the AF entity receives a network resource analysis result from at least one grid of the N grids of the network device in step 502, the method further includes: the AF entity sends a second request to the network device.

The second request is used for requesting to obtain the network resource analysis result, and the second request carries information of at least one grid, for example, an identifier of the at least one grid, coverage information, and the like.

In a possible implementation manner, after step 501, or after the AF entity sends the second request to the network device, the method further includes: the AF entity receives a network resource analysis result from at least one grid of the N grids of the network device. When the network resource analysis result satisfies a third preset condition, the AF entity sends the QoS parameter of the V2X service to the UE in the at least one grid that performs the V2X service provided by the AF entity. The QoS parameters of the V2X service can be referred to the related description in step 402.

Wherein the third preset condition may include: and the parameter value in the network resource analysis result is in a third preset range, or the network resource analysis result comprises adjustment indication information and the like.

The third preset condition may be the same as or different from the first preset condition or the second preset condition.

Wherein, the adjustment indication information may include QoS parameter adjustment indication information of the V2X service. The QoS parameter adjustment indication information of the V2X traffic is used to indicate that the QoS parameter of the V2X traffic of the UE within the coverage of the at least one grid needs to be adjusted.

Therefore, in the embodiment of the present application, the AF entity may adjust the QoS parameter of the V2X service of the UE within the coverage of at least one grid according to the network resource analysis result from the network device, so that the UE may perform the V2X service using the QoS parameter more matched with the channel quality of SL communication, and may perform the V2X service using the QoS parameter of the V2X service delivered by the AF.

In another implementation, when the network resource analysis result satisfies the third preset condition, the AF entity may also send the QoS parameter of the V2X service to the PCF entity through the NEF entity, and the PCF entity sends the QoS parameter of the V2X service to the UE performing the V2X service provided by the AF entity in the at least one grid through the AMF entity, so that the AF entity indirectly adjusts the QoS parameter of the V2X service of the UE within the coverage of the at least one grid through the PCF entity.

Based on the data processing methods provided in fig. 2-5, the data processing methods provided in the present application will be further described below.

601. And the access network equipment performs map rasterization.

The access network equipment performs grid division on a preset range based on the information of the map to obtain the information of N grids in the preset range, wherein N is a positive integer greater than or equal to 1. For map rasterization in step 601, reference may be made to the related description in the second method in step 202.

Specifically, after map rasterization is performed on the access network device, information of N grids is obtained. The information of the N grids can be referred to the related description in step 201 above.

Each grid of the N grids has a corresponding identifier, and one grid may correspond to one identifier. The identifier of each grid may be allocated to each grid when the access network device divides the grid; or after the grid division is completed, the access network device allocates an identifier to each grid. Specifically, the identifier of each grid may be allocated according to a preset rule. For example, the identifier may be allocated to each grid according to the order of grid division, may be randomly allocated to each grid, may be allocated to each grid according to the order of arrangement of each grid, and the like.

The preset range may be a cell coverage range under the access network device, a sector coverage range under the access network device, or a range defined by the access network device or other network elements according to a preset rule based on a map, for example, the preset range may be a road area on the map.

The N grids may be obtained by dividing a preset range by the access network device according to a preset size. For example, the access network device may divide the road according to a preset length, width, or height (altitude), etc., to obtain N grids. The coverage of each of the N grids may be less than a preset range. For example, the coverage area of each grid may be smaller than the coverage area of one or more cells under the access network device, or the size of the coverage area of each grid may be smaller than the average coverage area size of the cells under the access network device, etc.

It should be noted that the shape of each grid may be a rectangle, a circle, a polygon, or the like, and the shape of each grid may be the same or different, and may be specifically adjusted according to the actual application scenario.

In one example, the preset range is taken as an example of a road in a map. As shown in fig. 7A, the access network device may perform rasterization processing based on road information of the map information, dividing the road into a plurality of grids. The width of the road may be defined as the width of each grid, and the length of each grid may be determined according to the operator's setting. It can be understood that the access network device segments roads on the map, each road segment is a grid, and the length of each road segment can be set by an operator. When the width of the grid is the width of the road, the value of the width may be different in different scenes. For example, the width of a lane of an urban road is 3.5 meters, the width of a lane of an intersection diversion lane is 2.3-2.5 meters per lane, the width of a highway (including an expressway) per lane is 3.75 meters, and the width of a shoulder (an expressway emergency stop belt) is 1.5-2.5 meters. Also, there may be scenes of elevated roads, tunnels, etc. Thus, in some specific application scenarios, the coverage information for each grid may also include altitude.

In one example, the above-mentioned preset range is taken as a cell under one or more base stations. As shown in fig. 7B. Taking a base station as an example, the base station includes one or more cells, and three cells are described here. The base station may divide the coverage areas of the three cells to obtain a plurality of grids. One cell may be divided into one or more grids, and the size of the coverage area of each grid is not greater than the size of the coverage area of the minimum cell under the base station.

In one example, the above-mentioned predetermined range is a sector under one or more base stations. The base station may also divide a sector into one or more grids based on the coverage of the sector within its coverage. As shown in fig. 7C. One base station may include one or more sectors, and three sectors are illustrated here. The base station may divide the coverage area of the three sectors to obtain a plurality of grids. The sector can be divided into one or more grids, and the size of the coverage area of each grid is not larger than that of the minimum sector under the base station.

In a possible implementation manner, when the access network device is one or more base stations, after the access network device divides and obtains information of N grids, each grid may be matched with one or more cells under one or more base stations. And then saving the information of the grids into the data of the corresponding cell. For example, cell a includes grid 1, grid 2, and grid 5 in the coverage area, and cell B includes grid 3, grid 4, and grid 6 in the coverage area, and the identities of grid 1, grid 2, and grid 5 may be stored in the data of cell a, the identities of grid 3, grid 4, and grid 5 may be stored in the data of cell B, and so on. In addition, other network elements, for example, an AMF entity, a NEF entity, etc., may also match the N grids with the one or more cells, and the process is similar to the way that the access network device matches the N grids with the one or more cells, and is not described again.

In another possible specific application scenario, in 3GPP TS 36.331(5.10.13.2), a region is divided based on a map, resulting in one or more partitions (zones). The PC5 resource may then be associated with the zone, for example, the PC5 resource may be saved in the data associated with the associated zone, with reference to the associated criteria. In this embodiment, the grid may be matched with the zone by an access network device, a PCF entity, or a network device, and the grid may be corresponding to the zone. Specifically, the information of the zone where each of the N grids is located may be stored in the information of each grid, or the information of each grid may be stored in the information of the zone where each grid is located.

The size of the coverage area of the grid provided by the application is smaller than the size of the average coverage area of the zone, or the size of the coverage area of the grid provided by the application is smaller than the size of the minimum coverage area of the zone. It is to be understood that, in the embodiment of the present application, the grid obtained based on map division may be a subset of the zone. For example, as shown in fig. 8, one zone may be divided into a plurality of grids. Where each grid has a corresponding PC5 resource. And, each zone has a corresponding zone Identification (ID). The identity of each grid may be associated with a zone ID. For example, the identification of each grid may include the zone ID of the corresponding zone. When the coverage of the zone needs to be adjusted subsequently, the coverage of the partition can be adjusted with the grid as the granularity. As shown in fig. 9, one or more of the grids in fig. 9 may be divided from zone a into zone B, as opposed to fig. 8. When the coverage of a zone is adjusted, only the identifier of the grid in the zone needs to be adjusted, for example, the identifier of the grid corresponding to the zone is added or deleted, and the longitude, the latitude, the length and the like of each zone do not need to be readjusted. The complexity of adjusting the zone may be reduced.

In a specific implementation manner, after step 601, the method further includes: the access network device sends the information of the N grids to other network elements, for example, a PCF entity, a data analysis entity, an NWDAF entity, or an AF entity, without limitation.

Alternatively, step 601 may be replaced with step 6011.

6011. The PCF entity performs map rasterization.

The map rasterizing step in step 601 may also be executed by the PCF entity. The step of map rasterization by the PCF entity is similar to the step of map rasterization by the access network device in step 601, and the access network device in step 601 may be replaced by the PCF entity, which is not described again.

In a specific implementation, after step 6011, the method further includes: the PCF entity sends the information of the N grids to other network elements, such as an access network device, an NWDAF entity, a data analysis entity, or an AF entity, without limitation.

Alternatively, step 601 may be replaced with step 6011.

6012. The AF entity performs map rasterization.

The step of rasterizing the map in step 601 described above may also be performed by the AF entity. The step of map rasterizing by the AF entity is similar to the step of map rasterizing by the access network device in step 601, and the access network device in step 601 may be replaced by the AF entity, which is not described again.

In a specific implementation, after step 6012, the method further includes: the AF entity sends the information of the N grids to other network elements, such as an access network device, an NWDAF entity, a data analysis entity, or a PCF entity, without limitation.

602. And the UE reports the first SL network information to the access network equipment.

The first SL network information may refer to the related description in step 202.

The UE may report the first SL network information to the access network device through Radio Resource Control (RRC) signaling.

There are various ways for the UE to report the first SL network information, as described below.

The first method is as follows: the UE may periodically report the first SL network information to the access network device.

The period of reporting the first SL network information may be written by the PCF entity into configuration information issued to the UE, and the UE reads the reporting period from the configuration information and then reports the first SL network information according to the reporting period. Or, the access network device carries an indication indicating that the UE periodically reports the first SL network information to the access network device in a signaling sent to the UE, and a reporting period, and the UE may periodically report the first SL network information to the access network device according to the signaling and the reporting period.

For example, when the UE initiates a V2X service request to the access network device or the PCF entity, or during the processes of the UE periodically performing configuration update or registration update, the PCF entity may issue configuration information to the UE through the AMF entity, where the configuration information may carry a period for the UE to report the first SL network information.

For another example, when the access network device sends a Radio Resource Control (RRC) signaling to the UE, the RRC signaling carries an indication instructing the UE to report the first SL network information to the access network device periodically, and a reporting period.

Therefore, in this embodiment, the UE may report the first SL network information periodically, for example, the UE reports the first SL network information to the access network device for f1 times per minute, so that the access network device may acquire the first SL network information periodically. Furthermore, the access network device may also periodically send the second SL network information to the network device, and periodically receive a network resource analysis result from the network device, thereby implementing the access network device periodically adjusting or allocating the network resource of the UE within the grid coverage. Furthermore, the UE can use the adjusted or distributed network resource to carry out SL communication, so that the efficiency of the UE for carrying out SL communication is improved, and the time delay of the UE for carrying out SL communication is reduced.

The second method comprises the following steps: and the UE reports the first SL network information according to the trigger condition.

The access network equipment carries information of triggering conditions for triggering the UE to report the first SL network information to the access network equipment in a signaling sent down to the UE.

Wherein the trigger condition may include: the CBR is lower than a preset threshold, or the current channel quality cannot meet the current communication requirement, for example, the time delay of the UE for SL communication is higher than a first threshold, or the packet loss rate of the UE for SL communication is higher than a second threshold, and the like, which cannot meet the requirement of the V2X service.

Specifically, the access network device may carry the information of the trigger condition in RRC signaling sent to the UE.

Therefore, in this mode, when the UE determines that the CBR is lower than the preset threshold, or the UE monitors that the current channel quality cannot meet the current communication requirement, the UE may report the first SL network information to the access network device, so that the access network device may timely acquire the change in communication quality when the UE performs SL communication.

The third method comprises the following steps: when the access network equipment needs to acquire the first SL network information, the access network equipment directly issues reporting indication information for indicating the UE to report the first SL network information to the UE.

Further, after receiving the reporting indication information from the access network device, the UE may report the first SL network information to the access network device.

Therefore, in the third mode, the access network device may notify the UE to report the first SL network information according to the requirement, which may reduce the data amount sent by the UE and reduce the signaling overhead of the UE.

Further, after step 602, the method further comprises: the first SL network information may carry location information of the UE, and the access network determines that the UE is in the first grid according to the location information. For example, the first SL network information carries the longitude and latitude of the location of the UE, and the access network device may determine that the UE is in the first grid according to the longitude and latitude of the location of the UE and the longitude and latitude coordinates of each grid, or convert the longitude and latitude of the location of the UE carried in the first SL network information into the planar coordinates, and compare the planar coordinates with the longitude and latitude coordinates of each grid after conversion, where the first grid is included in the N grids.

603. And the access network equipment performs data preprocessing.

Wherein, step 603 in the embodiment of the present application is an optional step.

After receiving the first SL network information sent by the UE, the access network device may perform preprocessing on the first SL network information to obtain second SL network information.

The specific steps of the preprocessing and the second SL network information may refer to the related description in step 203.

In an example, if there are two UEs reporting first SL network information of SL communication to the access network device in the first frequency band, the first grid, and the first time period, the access network device may perform preprocessing on the first SL network information reported by the two UEs in the first frequency band, the first grid, and the first time period, for example, perform weighting, averaging, and the like on data included in the first SL network information, so as to obtain preprocessed SL network information. Therefore, in the embodiment of the present application, the data redundancy of the first SL network information may be reduced and the efficiency of the network device for performing data analysis may be improved by preprocessing the first SL network information by the access network device.

In one example, if there are multiple CBRs currently used or monitored by the UE reported in the same grid, the access network device performs weighted average or other quantization operations on the CBRs reported by the multiple UEs to obtain one CBR corresponding to each grid, so as to reduce redundancy of the CBRs of the same grid.

In a possible implementation manner, if there are multiple sets of first SL network information, where each set of first SL network information in the multiple sets of first SL network information may carry different information of a corresponding UE, for example, information of a location of each UE, information of a V2X service executed by each UE, and the like, for the different information in each set of first SL network information, the information may be directly included in the second SL network information without performing preprocessing.

In an optional implementation manner, the access network device periodically pre-processes the first SL network information, and a period of pre-processing the first SL network information is usually less than a period of reporting the first SL network information by the UE in step 602. For example, the access network device may perform f2 pre-processing on the first SL network information every minute, where f2 is smaller than f1 in step 602 above.

In another implementation, when the data analysis entity is deployed independently from the access network device, step 603 may also be performed by the data analysis entity, and the access network device sends the first SL network information to the data analysis entity after receiving the first SL network information. The process of preprocessing the first SL network information by the data analysis entity is similar to the step of preprocessing the first SL network information by the access network device, and is not described again.

604. The access network device sends the identifier of the first grid and the second SL network information to the network device.

Step 604 in this embodiment is similar to step 203 described above, and is not described herein again.

Furthermore, when step 603 is performed by the data analysis entity, the data analysis entity may also send the identification of the first grid and the second SL network information to the NWDAF entity.

605. The access network device sends a SL network performance prediction request to the network device.

The SL network performance prediction request sent by the access network device to the network device, that is, the first request in step 203, specifically refer to the relevant description in step 203, and details are not described here.

In one possible implementation, the access network device may send the SL network performance prediction request, the identifier of the first grid, and the second SL network information through the same message.

Specifically, in step 605, it may be understood that, when the access network device needs to predict the SL network performance of some areas, the second SL network information and the identifier of the first grid to which the area that needs to be subjected to SL network performance prediction belongs may be sent to the network device, so as to request the network device to obtain a network resource analysis result of at least one grid, where the at least one grid may be the first grid or the first grid and grids in the vicinity of the first grid. The network resource analysis result may be used by the access network device to adjust or allocate network resources used by the UE.

In a specific implementation manner, the access network device may periodically send a SL network performance prediction request to the network device to request a network resource analysis result of at least one grid, so as to implement real-time regulation and control of network resources used by UEs in the at least one grid. For example, the access network device may send the SL network performance prediction request f3 times per minute to the network device, where f3 is smaller than f2 in step 603 described above. And, when the access network device sends the SL network performance prediction request, the access network device carries the second SL network information in the current period, where the second SL network information please refer to the related description in step 203.

In another specific implementation, the access network device may send the SL network performance prediction request to the network device according to the triggering event. The triggering event may include: and the UE requests the access network equipment to allocate network resources, or the CBR value reported by the UE is greater than a preset value, or the road information vehicle density value reported by the UE is greater than a preset vehicle density value, and the like.

Specifically, when the access network device may send the SL network performance prediction request, the identifier of the first grid, and the second SL network information through the same message. The second SL network information may be the first SL network information in step 602, or may be SL network information obtained by preprocessing the first SL network information.

Two scenarios, i.e., the preprocessed SL network information and the unprocessed first SL network information, are exemplarily illustrated.

And in the first scene, the access network equipment sends the preprocessed SL network information to the network equipment.

Specifically, when the access network device sends the SL network performance prediction request, the identifier of the first grid, and the processed data of the first SL network information to the network device through the same message, the specific content of the message may refer to table 1.

TABLE 1

The content requested by the access network device from the network device, that is, the content may be understood as a SL network performance prediction request, may include QoS levels supported by SL communication under the coverage of at least one grid (including the grid of the first grid near the first grid in table 1), or a congestion level of SL communication under the coverage of at least one grid.

The information of the first grid and the information of the grid near the first grid in table 1 may include the identifier of the first grid and the second SL network information. A grid near the first grid may be understood as a grid adjacent to the first grid.

The information of the first grid may include a timestamp, an ID of the first grid, a frequency band of the UE for SL communication, channel quality reference information, CBR information (preprocessed data), and the like. Optionally, the information of the first grid further includes one or more of the number of UEs under the first grid, UE IDs of UEs within the coverage of the first grid, movement tracks of UEs within the coverage of the first grid, information of V2X services of UEs within the coverage of the first grid (for example, the channel occupancy of V2X service, V2X service, or priority of data packets of V2X service being performed by the UEs, see the related description in step 202 above), road information perceived by the UEs (for example, local traffic flow density, vehicle driving speed, temperature, humidity, visibility, and the like, see the related description in step 202 above), and the like. The frequency band, channel quality reference information, and CBR information of the UE performing SL communication are preprocessed data, and the preprocessing step refers to the related description in step 203. The information of the grid near the first grid is similar to that of the first grid and is not described again.

In this scenario one, the access network device may send the preprocessed SL network information to the network device, which may reduce the redundancy of the sent data and improve the data sending efficiency. Moreover, when the network device receives the preprocessed SL network information, the data amount of the preprocessed SL network information is less than that of the SL network information which is not preprocessed, so that the network device can obtain a network resource analysis result based on less SL network information, the workload of the network device can be reduced, and the working efficiency of the network device can be improved.

And in the second scenario, the access network equipment sends the SL network information which is not preprocessed to the network equipment.

When the access network device sends the SL network performance prediction request, the identifier of the first grid, and the first SL network information without being preprocessed to the network device through the same message, the specific content of the message may refer to table 2.

TABLE 2

The contents included in table 2 are similar to those included in table 1, and the description of the similar contents is omitted. The difference is that the frequency band, channel quality reference information, and CBR information for SL communication by UEs in the coverage area of the first grid and grids near the first grid, which are carried in table 2, are data without preprocessing.

In the second scenario, if the access network device sends the non-preprocessed SL network information to the network device, it may carry a large amount of first SL network information related to the first grid. The network device can more accurately acquire the use condition of the network resource under each grid according to the non-preprocessed SL network information. In practical application, when the SL performance prediction request is sent, the more accurate the data carried in the SL network performance message is, the more accurate the subsequent network resource analysis result is.

It should be noted that step 605 in the embodiment of the present application is an optional step, and step 605 may not be executed, or step 605 may also be executed, which is not limited.

Alternatively, step 605 may be replaced with 6051.

6051. The AF entity sends a SL network performance prediction request to the network device.

The above step 605 may also be performed by the AF entity.

The SL network performance prediction request sent by the AF entity to the network device is the second request in step 502 above. The SL network performance prediction request is for requesting network resource analysis results for at least one grid from the network device.

The AF entity may not acquire the SL network information of the UE in at least one grid, and therefore, the SL network performance prediction request sent by the AF entity to the network device may not carry the second SL network information, and the access network device sends the second SL network information to the network device.

Specifically, the manner in which the AF entity sends the SL network performance prediction request to the network device may refer to the manner in which the access network device sends the SL performance prediction request to the network device in step 605.

In a specific implementation manner, if the AF entity stores information of N grids, the SL network performance prediction request sent by the AF entity to the network device may carry information of at least one grid, for example, an identifier, a coverage area, and the like of the at least one grid.

In another specific implementation manner, when the AF entity does not store the information of N grids, the AF entity may carry the location information corresponding to the network resource analysis result to be obtained in the SL network performance prediction request sent to the network device. For example, the SL network performance prediction request may carry: the longitude and latitude of the area requested to be predicted, or information of a single or multiple paths of the UE, or coordinate information of a geometric area of the range requested to be predicted, and the like. The network device may determine, according to the location information of the UE carried in the SL network performance prediction request, at least one grid corresponding to a network resource analysis result requested to be obtained by the AF entity. Therefore, even if the AF entity does not include information of N grids, the location information of the requested area can be sent to the network device, and the network device can be requested to obtain the network resource analysis result.

606. And the network equipment performs data analysis.

Step 606 in the present embodiment may refer to step 303 above, and is not described herein again.

There are various ways to trigger the network device to perform data analysis, as described below.

The first method is as follows: the network device may be triggered by the SL network performance prediction request for data analysis after step 605 or 6051.

In the first method, the content included in the network resource analysis result may be different according to the difference of the content of the request carried in the SL network performance prediction request.

For example, if the SL network performance prediction request is used to request the network device to analyze the congestion condition of the SL communication, the network resource analysis result carries the congestion degree of the SL communication. If the SL network performance prediction request is used to request the network device to analyze the QoS levels supported by the SL communication, the network resource analysis result may include the QoS levels supported by the SL communication. If the SL network performance prediction request is used to request the network device to analyze a part of QoS parameter indicators in the SL communication, the network resource analysis result may include an indication of the QoS parameter indicators of the at least one grid that can meet the requirement of the V2X service, for example, the network resource analysis result may include an indicator of delay or packet loss rate, or the network resource analysis result may directly include an indication of whether the QoS parameter indicators of the V2X service are met, or the like.

In a possible scenario, when the SL network performance prediction request is sent by an AF entity, and the AF entity does not store the information of the N grids, the SL network performance prediction request carries information of a position that needs to be requested, and after receiving the SL network performance prediction request, the network device determines at least one grid corresponding to the position information according to the position information carried in the SL network performance prediction request. And further analyzing the network resources of the at least one grid to obtain a network resource analysis result.

The second method comprises the following steps: after step 604, data analysis may be performed.

In the second mode, if the access network device periodically sends the identifier of the first grid and the second SL network information related to the first grid to the network device, the network device may also periodically analyze the network resources of the at least one grid based on the identifier of the first grid and the second SL network information related to the first grid, so as to obtain a network resource analysis result of the at least one grid. The period of analyzing, by the network device, the network resource of at least one grid may be adjusted according to the period of sending, by the access network device, the identifier of the first grid and the second SL network information related to the first grid.

In one example, the access network device may periodically send the SL network performance prediction request and the second SL network information within a preset time period to the network device. For example, the access network device may send the second SL network information to the network device within 5 minutes. So that the network device can obtain the network resource analysis result of the at least one grid based on the SL network performance prediction request and the second SL network information within the preset time period. The network resource analysis result may include information of communication quality of the SL communication within the at least one raster coverage in a future preset time period. Specifically, the network device may take second SL network information acquired in a preset time period as an input according to a preset algorithm, for example, a kalman filter algorithm, a neural network algorithm, and the like, and output a network resource analysis result of the at least one grid, where the network resource analysis result may include information of communication quality of SL communication within a coverage range of the at least one grid in a preset time period in the future. The preset time period may be determined by the network device according to the prediction algorithm, or may be directly determined by the access network device.

Therefore, the access network device may send a SL network performance prediction request and second SL network information in a preset time period to the network device, requesting a network resource analysis result of the at least one grid, so that the access network device may adjust the network resource of the UE based on the predicted network resource analysis result of the at least one grid in the future preset time period. It can be understood that, through a kalman filter algorithm or a neural network algorithm, the communication quality of the SL communication is analyzed or predicted based on the granularity of the grid, and then, based on the result of the analysis or prediction of the communication quality of the SL communication, the network resource of the UE can be accurately adjusted, so as to avoid the situation that the UE has channel congestion during the SL communication.

607. The network equipment sends the network resource analysis result to the PCF entity.

After obtaining the network resource analysis result of at least one grid, the network device may send the network resource analysis result of the at least one grid to the PCF entity.

Specifically, if the network device periodically analyzes the network resources of at least one grid, the network device may periodically send the network resource analysis result to the PCF entity.

It should be noted that step 607 in this embodiment of the present application is an optional step, that is, the network device may not send the network resource analysis result of at least one grid to the PCF entity.

608. And the network equipment sends the network resource analysis result to the AF entity.

After obtaining the network resource analysis result of the at least one grid, the network device may send the network resource analysis result of the at least one grid to the AF entity.

Specifically, there are various ways for triggering the network device to send the network resource analysis result to the AF entity, as described below.

The first method is as follows: the network device periodically sends the network resource analysis result to the AF entity. For example, if the network device periodically analyzes the network resources of at least one grid, the network device may periodically send the network resource analysis result to the AF entity.

The second method comprises the following steps: the network device receives the SL network performance prediction request from the AF entity and sends the network resource analysis result to the AF entity.

More specifically, the network device may forward the network resource analysis result to the AF entity through the NEF entity.

609. And the network equipment sends the network resource analysis result to the access network equipment.

After obtaining the network resource analysis result of at least one grid, the network device may send the network resource analysis result of the at least one grid to the access network device.

Specifically, there are various ways for triggering the network device to send the network resource analysis result to the access network device, as described below.

The first method is as follows: the network device periodically sends the network resource analysis result to the access network device. For example, if the network device periodically analyzes the network resources of at least one grid, the network device periodically sends the network resource analysis result to the access network device.

The second method comprises the following steps: the access network equipment sends the SL network performance prediction request to the network equipment, and the network equipment sends the network resource analysis result to the access network equipment.

610. And the access network equipment sends the information of the network resources to the UE.

The information of the network resource is information of a network resource available to the UE, or information of a network resource allocated to the UE by the access network device. When the information of the network resource is information of a network resource available to the UE, the information of the network resource may be sent to the UE by the access network device through the SL radio bearer configuration. When the network resource information is information of network resources allocated to the UE by the access network device, the access network device may directly send the information of the network resources to the UE.

After receiving a network resource analysis result of at least one grid from a network device, an access network device sends SL radio bearer configuration to UE within a coverage range of the at least one grid when the network resource analysis result meets a first preset condition; or, when the network resource analysis result meets the first preset condition, the access network device allocates network resources to the UE in the at least one grid coverage range according to the network resource analysis result, and sends information of the allocated network resources to the UE.

Step 610 may refer to the above description of step 203, and step 610 is described in more detail in some specific scenarios.

For example, the network resource analysis result carries QoS levels supported by SL communication in at least one grid range. Correspondingly, the first preset condition is that the QoS level carried in the network resource analysis result is lower than the preset QoS level. Therefore, when the network resource analysis result satisfies the first preset condition, the UE in the at least one grid needs to adjust the network resource used for SL communication. The access network device may issue a SL radio bearer to the UE in the at least one grid, where the SL radio bearer may include information of network resources available to the UE, so that the UE may select available network resources for SL communication according to the SL radio bearer.

The access network device may send the SL radio bearer configuration to the UE through RRC signaling or a System Information Block (SIB) message.

In general, the access network device may send the SL radio bearer configuration to the UE within the at least one grid coverage area informing the UE of the available PC5 resources. Specifically, the access network device may configure corresponding PC5 resources for the UE according to PC5 authorization information or QoS parameters and the like included in communication parameters of the V2X service of each UE. For example, the higher the QoS class of the UE, the more PC5 resources are allocated to the UE; alternatively, the more PC5 resources the UE is authorized to use, the more available PC5 resources are allocated to the UE.

For another example, if the network resource analysis result carries a value representing a congestion degree in at least one grid, the first preset condition may be that the value indicating the congestion degree in at least one grid exceeds a preset value. Then, after the value exceeds the preset value, the access network device determines that the network resource analysis result meets a first preset condition, which may be understood that the congestion level of SL communication in at least one grid is high, and network resources used by the UE in the coverage area of the at least one grid when performing the V2X communication service need to be adjusted. The access network device may allocate network resources for SL communication to the UE according to the network resource result, and send information of the network resources for SL communication allocated to the UE. Further, the UE may update the network resource configuration according to the information of the network resource allocated by the access network device for the UE to perform SL communication, and use the access network device to allocate the network resource for the UE to perform SL communication.

In an example, the frequency band of the direct communication that can be used by the UE when performing the V2X service is 5905-. When the density of vehicle nodes on a road is too large, a channel congestion situation easily occurs in a direct-through working frequency band with a bandwidth of 20 MHz. When the access network device determines that the network resource analysis result meets the first preset condition, it may be understood that the communication quality of the current SL communication is poor, or a channel congestion condition occurs. The access network equipment may send the SL radio bearer configuration to the UE informing the UE of available PC5 resources so that the UE may select PC5 resources for communication, or the access network equipment may allocate PC5 resources to the UE according to the network resource analysis result. Therefore, in this example, the UE may perform SL communication through the available PC5 resource or the allocated PC5 resource, so as to improve the communication efficiency of the UE for SL communication and avoid channel congestion when the UE performs SL communication.

Generally, the SL radio bearer configuration may also be understood as a preconfigured SL radio bearer, that is, the access network device predicts, according to a network resource analysis result obtained by the network device analysis, a situation that the communication quality of SL communication is poor or a channel is congested, so that the situation that the communication quality is poor or the channel is congested when the UE performs the SL communication is avoided through the preconfigured SL radio bearer.

611. The PCF entity sends communication parameters for the V2X service to the UE.

Step 611 in the embodiment of the present application may refer to the related description after step 402, which is not described herein again.

When the network resource analysis result of at least one grid meets a second preset condition, the communication quality of the network resource in the at least one grid is poor, and the situations of high time delay, low transmission efficiency and the like may exist. Therefore, when the network resource analysis result satisfies the second preset condition, the PCF entity may send the communication parameters of the V2X service to the one or more UEs within the coverage area of the at least one grid according to the network resource analysis result, thereby implementing the adjustment of the communication parameters of the V2X service for the one or more UEs within the coverage area of the at least one grid.

For example, if the communication quality of the SL communication in at least one grid is poor and the QoS level supported by the SL communication is lowered, the PCF entity may lower the QoS level of the V2X service of the UE within the range of the at least one grid by issuing the communication parameter of the V2X service to adapt to the change of the communication quality of the SL communication, so as to avoid the occurrence of channel congestion of the SL communication. Or, the PCF entity sends the communication parameters of the V2X service to the UE, and adjusts the frequency band used by the UE when performing the V2X service, so as to avoid the UE communicating in the frequency band with poor channel quality, improve the communication quality of the UE performing SL communication, and reduce the communication delay of the UE.

For another example, if the channel communication quality in at least one grid is good and the QoS level supported by the SL communication is improved, the PCF entity may correspondingly improve the QoS level of the V2X service of the UE in the at least one grid range by issuing the communication parameter of the V2X service, so as to adapt to the communication quality of the SL communication and improve the communication quality of the UE in the SL communication. Or, the PCF entity sends the communication parameters of the V2X service to the UE, and adjusts the frequency band used by the UE when performing the V2X service, so that the UE communicates in the frequency band with better channel quality, and the communication quality of the SL communication performed by the UE can be improved, and the delay of the SL communication performed by the UE is reduced.

612. The AF entity sends the QoS parameters of the V2X traffic to the UE.

Step 612 in the embodiment of the present application may refer to the related description in step 502 above, and is not described herein again.

The V2X service indicated in this step is a service provided by the AF entity for the UE. For example, the vehicle shares sensor information services, the vehicle periodically broadcasts status information services such as own position, speed and the like, the vehicle forwards information services of other vehicles or roadside devices and the like.

Specifically, the network resource analysis result may refer to the related description of step 203.

When the network resource analysis result satisfies the third preset condition, it may be understood that the communication quality of the network resource in the at least one grid is poor, and there may be situations of high transmission delay, low transmission efficiency, and the like. Therefore, when the network resource analysis result satisfies the third preset condition, the AF entity may send, to one or more UEs within the at least one grid coverage area, QoS parameters of V2X traffic according to the network resource analysis result, which may be used to adjust the QoS parameters of V2X traffic of the UE.

Therefore, the AF entity can adjust the QoS parameter of the V2X service of the UE based on the grid granularity through the network resource analysis result based on the grid granularity, and more accurately adjust the QoS parameter of the V2X service of the UE.

For example, if the communication quality of the SL communication in at least one grid is poor and the QoS level supported by the SL communication is decreased, the AF entity may issue the QoS parameter of the V2X service to the UEs within the at least one grid, and decrease the QoS level of the V2X service of the UEs within the at least one grid. Thereby avoiding the situation where the channel for SL communication is congested.

For another example, if the channel communication quality in at least one grid is good, the QoS level supported by SL communication is increased. The AF entity may issue the QoS parameter of the V2X traffic to the UEs within the at least one grid range, and increase the QoS level of the V2X traffic of the UEs within the at least one grid range. Therefore, the communication quality of the UE for SL communication is improved, and the communication time delay of the UE is reduced.

In one example, after receiving the network resource analysis result from at least one grid of the network device, the AF entity may understand that the communication quality of the PC5 resource within the coverage of the at least one grid may be poor or a channel congestion may occur if the network resource analysis result satisfies a third preset condition. Therefore, the AF entity may transmit the QoS parameters of the V2X traffic to the UE in the coverage of the at least one grid, which is engaged in the V2X traffic. So that the UE can configure the QoS parameters of the V2X service executed by itself according to the QoS parameters of the V2X service. Therefore, the AF entity can make the QoS parameter of the V2X service of the UE adapt to the communication quality of the SL communication more by adjusting the QoS parameter of the V2X service of the UE, improve the communication efficiency of the SL communication performed by the UE, and reduce the communication delay of the UE.

In a specific scenario, in step 611, the QoS parameters included in the communication parameters of the V2X service sent by the PCF entity to the UE may be sent by one or more AF entities to the PCF entity, and then sent by the PCF entity to the UE. Specifically, the AF entity may be an entity corresponding to the V2X service. The communication parameters of the V2X traffic sent by the PCF entity to the UE may include communication parameters of one or more V2X traffic of the UE, and the communication parameters of the one or more V2X traffic may include QoS parameters of the one or more V2X traffic. The QoS parameters of the one or more V2X services may be sent by the AF entity corresponding to the one or more V2X services to the PCF entity through the NEF entity, and then sent by the PCF entity to the UE.

Therefore, in the embodiment of the present application, one of the access network device, the PCF entity, or the AF entity performs map rasterization, and notifies other network elements of the information of N grids obtained by the rasterization. The UE within the coverage of the first grid may report the first SL network information to the access network device, and the access network device may send the identifier of the first grid and second SL network information related to the first grid to the network device. And the network equipment can obtain the network resource analysis result of at least one grid based on the information of the N grids, the identification of the first grid and the second SL network information. And sending the network resource analysis result to the access network device, the PCF entity and/or the AF entity, so that the access network device, the PCF entity and/or the AF entity can adjust the network resources of the UE, the communication parameters of the V2X service or the QoS parameters of the V2X service, and avoid the situations that the UE within the coverage of the at least one grid has poor communication quality or cannot communicate due to channel congestion of SL communication.

The above detailed description is made on a specific flow of the data processing method provided by the present application, and some specific application scenarios of the data processing method provided by the present application are described below.

And in the first scene, map rasterization is carried out by access network equipment.

Referring to fig. 10, another flow chart of the data processing method provided in the present application is described as follows.

1001. And the access network equipment performs map rasterization.

In the embodiment of the present application, map rasterization is performed by the access network device to obtain information of N grids. Please refer to the related description in step 201 above for the information of the N grids.

For example, after obtaining the information of the map, the access network device divides the roads in the map into N segments based on the information of the map, that is, N grids are obtained. The length of each grid, i.e. the length of the N segments, the width of each grid, i.e. the width of the road, or the width of each grid is greater than the width of the road.

When the access network device is a base station, there may be multiple base stations. Each base station can perform grid division on roads in the coverage area of the base station, and the plurality of base stations perform grid division to obtain information of N grids. When the base station performs grid division, the size of the coverage area of each grid may be smaller than the size of the coverage area of the smallest cell under the base station, so that the granularity of the divided grid is smaller than the granularity of the cell. Or, when the base station performs grid division, the size of the coverage area of each grid may be smaller than the size of the coverage area of the smallest sector under the base station, so that the granularity of the divided grids is smaller than the granularity of the sectors.

Specifically, the shape of each grid may be circular, elliptical, square, or other polygonal shapes, etc., and the shape of each grid may not be the same. Therefore, the coverage information of each grid may include different contents. For example, if the grid is circular, the coverage information of the grid may include the longitude and latitude of the center of the circle, the radius, and the indication data indicating that the grid is circular. If the shape of the grid is a polygon, the coverage information of the grid may include the longitude and latitude of the position of each vertex, or may further include indication data indicating that the shape of the grid is a polygon.

The specific step of the access network device performing map rasterization may refer to step 601, which is not described herein again.

1002. And the access network equipment sends the information of the N grids to the NWDAF entity.

After the access network device performs map rasterization to obtain information of N grids, the access network device may send the information of N grids to the NWDAF entity.

1003. The access network equipment sends the information of the N grids to the PCF entity.

After the map rasterization is performed by the access network device to obtain the information of the N grids, the information of the N grids can be sent to the PCF entity.

1004. And the UE reports the first SL network information to the access network equipment.

1005. And the access network equipment performs data preprocessing.

1009. And the NWDAF entity sends the network resource analysis result to the access network equipment.

Step 1009 in this embodiment may refer to step 609 above, which is not described herein again.

For example, after the NWDAF entity performs data analysis to obtain a network resource analysis result of at least one grid, the network resource analysis result is sent to the access network device. The network resource analysis result can be understood as the QoS level, congestion level or QoS KPI condition supported by the SL communication in the coverage area of the at least one grid in a certain period of time later.

Step 1011 in the embodiment of the present application may refer to step 610, which is not described herein again.

After the access network device receives the network resource analysis result from the NWDAF entity, if the network resource analysis result meets a first preset condition. It is understood that, in a certain period of time later, the communication quality of the SL communication within the coverage area of the at least one grid is poor, for example, the QoS level supported by the SL communication is lowered or the channel congestion level is high. The access network device may adjust or allocate PC5 resources for, or to be in, the at least one grid of coverage UEs such that the UEs may communicate using the available PC5 resources. The communication efficiency of the UE in the at least one grid can be improved, and the channel congestion degree of SL communication in the coverage area of the at least one grid can be reduced.

Generally, for some UEs with higher priority, high importance of service data, or large amount of transmitted data, the access network device may configure more PC5 resources, so that communication transmission of such UEs may be guaranteed, and reliability of communication transmission may be improved.

1012. The PCF entity issues a control strategy and communication parameters of the V2X service to the UE.

Therefore, the PCF entity may also issue control policies and communication parameters for V2X traffic to at least one UE within the grid coverage. The control policy may be used to inform the UE in which time periods or frequency bands or used PC5 interface or Uu interface data transmission for V2X traffic is performed. Therefore, the UE in the coverage area of the at least one grid is prevented from using the same interface for communication in the same time period or the same frequency band, so that the channel congestion degree of SL communication covered by the at least one grid is reduced.

Generally, when the QoS level supported by SL communication is low, the PCF entity may lower the QoS level of V2X traffic for UEs within the coverage of the at least one grid by issuing communication parameters of V2X traffic to the UEs, or lower the QoS level of V2X traffic for some UEs where the importance of transmitted data is low. When the QoS level supported by the SL communication is higher, the PCF entity may also raise the QoS level of the V2X service for the UE in the coverage of the at least one grid by issuing the communication parameters of the V2X service to the UE.

Specifically, the PCF entity may send the control policy and the communication parameters of the V2X service to the UE in the coverage area of the at least one grid or the UE about to enter the coverage area of the at least one grid through a downlink-access stratum (NAS) message via the AMF entity.

In addition, if the access network device does not send the information of the N grids to the PCF entity after performing map rasterization, the NWDAF entity may carry the information of at least one grid, for example, the identifier coverage information of the at least one grid, when sending the network resource analysis result of the at least one grid to the PCF entity. In addition, the NWDAF entity may also send the information of the N grids to the PCF entity; or after receiving the network resource analysis result of at least one grid, the PCF entity requests the access network device for information of the N grids, etc.
