Fig. 1 shows a schematic diagram of an application scenario to which the technical solution of the embodiment of the present application may be applied.

In the application scenario shown in fig. 1, RSUs are disposed beside the road, and each RSU covers a certain area of the road. It should be noted that the RSU setting positions and the number of RSUs shown in fig. 1 are only schematic, and any number of RSUs may be set on both sides of the road according to actual needs, and the coverage areas between the RSUs may be overlapped or discontinuous.

In an embodiment of the present application, a network side device (e.g., a V2X application server) may configure RSU information for a VRU terminal, such as coverage area information (e.g., area 101, area 102, and area 103 shown in fig. 1) of each RUS, frequency point information of each RSU, transmission resource information of each RSU, and the like. After obtaining the information of the road side unit configured by the network side device, the VRU terminal may determine a network access policy according to the information of the road side unit configured by the network side device and state information (such as location information, power information, information of the VRU service to be processed, and the like) of the VRU terminal itself, so as to perform network access processing based on the determined network access policy.

Specifically, as shown in fig. 1, for example, when a user 105 enters an area 101 with a VRU terminal, the VRU terminal carried by the user 105 may determine that the VRU terminal is located within the coverage of the rsu 10 at this time according to the location of the VRU terminal and the rsu information configured by the network side device, and then the determined network access policy may be to access the rsu 10, and further may detect and access the rsu 10, and after accessing the rsu 10, VRU communication may be performed.

For another example, when the user 107 enters the area 102 with the VRU terminal, the VRU terminal carried by the user 107 may determine that the VRU terminal is located within the coverage of the RSU 30 at this time according to the location position of the VRU terminal and the RSU information configured by the network-side device, and at the same time, the VRU terminal carried by the user 107 determines that the VRU service processed by the VRU terminal is very important and sufficient in electric quantity, and may be simultaneously accessed to the RSU and the mobile communication network, so the network access policy determined by the VRU terminal carried by the user 107 may be simultaneously accessed to the RSU 30 and the mobile communication network, and after being simultaneously accessed to the RSU 30 and the mobile communication network, the VRU communication may be performed through the RSU 30 and the mobile communication network.

After receiving the registration message, the road side unit currently accessed by the VRU terminal may obtain the road side unit information configured for the VRU terminal from the application server for vehicle communication according to the application layer identifier of the VRU terminal, and then send the obtained road side unit information configured for the VRU terminal to the VRU terminal according to the application layer identifier of the VRU terminal. That is, in this embodiment, the road side unit currently accessed by the VRU terminal acquires the road side unit information configured for the VRU terminal from the application server according to the application layer identifier of the VRU terminal, and sends the road side unit information configured by the application server to the corresponding VRU terminal based on the application layer identifier of the VRU terminal.

That is, in this embodiment, the VRU terminal and the application server may directly interact through the V1 interface to obtain the configured rsu information.

In an embodiment of the present application, the process of the VRU terminal acquiring the road side unit information configured by the network side device may be sending an application layer request message to an application server for vehicle communication, and optionally, the application layer request message may be forwarded to the application server through a radio access network and a core network. After receiving the application layer request message, the application server may configure a target parameter for road side unit discovery, then send the target parameter to PCF (Policy Control Function) through NEF (network exposure Function), and then PCF generates configured road side unit information according to the target parameter, and forwards the information to AMF (Access and mobility Management Function), and then AMF sends the information to VRU terminal. That is, in this embodiment, the Application server transmits the configured Application-side parameters to the PCF as an AF (Application Function) through the NEF, and then the PCF generates final road-side unit information configured to the VRU terminal and transmits the information to the VRU terminal through the AMF.

In an embodiment of the present application, a process of acquiring, by a VRU terminal, roadside unit information configured by a network side device may be sending an application layer request message to an AF, and optionally, the application layer request message may be forwarded to the AF through a radio access network and a core network. After receiving the application layer request message, the AF may configure a target parameter for road side unit discovery, then send the target parameter to the PCF through the NEF, then the PCF generates configured road side unit information according to the target parameter, and forwards the configured road side unit information to the AMF, and then the AMF sends the configured road side unit information to the VRU terminal. That is, in this embodiment, the AF sends the configured application-side parameters to the PCF through the NEF, and then the PCF generates the final rsu information configured to the VRU terminal, and sends the information to the VRU terminal through the AMF.

Alternatively, the PCF may generate the configured rsu information for the VRU terminal after receiving the request message sent by the VRU terminal for obtaining the configured rsu information, and then send the configured rsu information to the VRU terminal through the AMF. Or the PCF can also actively generate the configured road side unit information and then configure the road side unit information to the VRU terminal through the AMF. Optionally, if the PCF needs to refer to the location information of the VRU terminal when generating the configured road side unit information, the PCF may obtain the location information of the VRU terminal from the access network side, or may also receive the location information reported by the VRU terminal.

It should be noted that, in the embodiment of the present application, the rsu information configured by the network side device may be preconfigured rsu information, may also be dynamically configured rsu information, and may also be dynamically updated rsu information that is preconfigured rsu information or dynamically configured rsu information before.

Continuing to refer to fig. 2, in step S220, a network access policy of the VRU terminal is determined according to the rsu information configured by the network-side device and the state information of the VRU terminal, where the network access policy includes whether to access the rsu configured by the network-side device.

In an embodiment of the application, if it is determined that the area where the VRU terminal is located is covered by the target rsu configured by the network-side device according to the rsu information configured by the network-side device and the state information of the VRU terminal, the determined network access policy may be to access the target rsu. In this embodiment, the status information of the VRU terminal is the location information of the VRU terminal.

In an embodiment of the application, if it is determined that the area where the VRU terminal is located or the target area to enter is not covered by the road side unit configured by the network side device according to the road side unit information configured by the network side device and the state information of the VRU terminal, but the VRU terminal needs to perform VRU communication, it is determined to access the mobile communication network. In this embodiment, the status information of the VRU terminal includes location information of the VRU terminal, service requirement information of the VRU terminal, and the like. Alternatively, the determination of the target area to which the VRU terminal is about to enter may be performed by means of trajectory prediction, such as determining that the VRU terminal is traveling along a route according to the historical location information of the VRU terminal, and then predicting the movement trajectory of the VRU terminal according to the movement direction of the VRU terminal and the determined route. Or modeling the positions of the VRU terminal at different moments by a machine learning model to generate a track prediction model, and predicting the movement track of the VRU terminal by the track prediction model.

In an embodiment of the present application, if it is determined that a target area to which a VRU terminal is to enter is not covered by a road side unit configured by a network side device according to road side unit information configured by the network side device and state information of the VRU terminal, the VRU terminal may be accessed to a mobile communication network before entering the target area, so as to ensure continuity of VRU services processed by the VRU terminal.

In an embodiment of the application, if it is determined that the area where the VRU terminal is located is covered by the target road side unit configured by the network side device according to the road side unit information configured by the network side device and the state information of the VRU terminal, whether to access the target road side unit and the mobile communication network simultaneously is determined according to the importance degree of the VRU service processed by the VRU terminal and the capability information of the VRU terminal.

In an embodiment of the application, if it is determined that the area where the VRU terminal is located is covered by the target rsu configured by the network-side device according to the rsu information configured by the network-side device and the state information of the VRU terminal, but the VRU terminal is accessed into one of the target rsu and the mobile communication network to meet the requirement of the VRU service, the determined network access policy may be accessed into one of the target rsu and the mobile communication network to meet the requirement of the VRU service.

In summary, the embodiment of the present application mainly provides a high-energy efficient VRU communication mechanism, that is, a VRU terminal performs RSU discovery by using information configured on a network side, so as to avoid power consumption waste caused by searching RSU by blind detection. The technical solution of the embodiment of the present application is described in detail below with reference to fig. 3 to 7:

in one embodiment of the present application, as shown in fig. 3, the communication connection between the VRU terminal and the V2X application server is in two ways: one is that the VRU terminal communicates with the V2X application server through the RSU; the other is that the VRU terminal communicates with the V2X application server through a cellular network (such as a 4G/5G network).

The communication between the VRU terminal and the V2X application server through the cellular network is mainly performed by the VRU terminal communicating with an access network device (i.e., a base station) through a PLMN band (Public Land mobile network band) based on a Uu interface, and interacting with the V2X application server through a core network.

The following details are set forth:

as shown in fig. 4, one embodiment of the VRU terminal communicating with the V2X application server includes the steps of:

in step S401, the VRU terminal encapsulates the VRU registration information into a container and sends the container to the RSU.

In step S402, the RSU transparently forwards the VRU registration information sent by the VRU terminal to the V2X application server to obtain VRU configuration information for RSU discovery.

In step S403, the V2X application server provides VRU configuration information for RSU discovery to the RSU.

In step S404, the RSU transparently forwards the VRU configuration information provided by the V2X application server to the VRU terminal.

In the embodiment shown in fig. 4, the RSU transparently forwards registration information and VRU configuration information between the VRU terminal and the V2X application server.

As shown in fig. 5, one embodiment of the VRU terminal communicating with the V2X application server includes the steps of:

in step S501, the VRU terminal sends VRU registration information to the RSU. The registration information includes Application layer identifiers of the VRU terminal, such as Application ID, PSID, ITS-AID, and the like.

In step S502, the RSU sends registration information to the V2X application server according to the application layer identifier of the VRU terminal, so as to obtain VRU configuration information for RSU discovery for the VRU terminal.

In step S503, the V2X application server provides VRU configuration information for RSU discovery to the RSU.

In step S504, after receiving the VRU configuration information provided by the V2X application server, the RSU sends the VRU configuration information to the VRU terminal according to the application layer identifier of the VRU terminal.

In the embodiment shown in fig. 5, it is necessary to define a set of application layer messages between the RSU and VRU terminals and introduce a corresponding application layer identity.

in step S601, the VRU terminal requests the V2X application server to provide VRU configuration information for RSU discovery through the V1 interface.

In step S602, the V2X application server provides VRU configuration information for RSU discovery to the VRU terminal through the V1 interface.

The technical scheme of the embodiment shown in fig. 6 enables the VRU terminal and the V2X application server to communicate through an application layer interface (i.e. V1 interface), and does not generate standardization impact on the 5G core network.

As shown in fig. 7, one embodiment of the VRU terminal communicating with the V2X application server includes the steps of:

in step S701, the VRU terminal sends an application layer request to the V2X application server to request the V2X application server to provide the VRU configuration information discovered by the RSU. The application layer request may be sent by the VRU terminal to the V2X application server through the NG-RAN (Next generation radio Access Network) and the core Network.

At step S702, the NEF delivers the configuration response sent by the V2X application server for RSU discovery to the PCF. Where the V2X application server interacts with the NEF as AF.

In step S703, the PCF generates VRU configuration information discovered by the RSU based on the configuration response, and then sends it to the AMF.

In step S704, the AMF configures VRU configuration information discovered by the RSU to the VRU terminal through NAS (Non-access stratum) layer signaling.

In the embodiment shown in fig. 7, the V2X application server provides, as the AF, the configuration response information on the application side, which affects the generation of the VRU configuration information finally discovered by the RSU, and the configuration response information is sent to the PCF via the NEF, and the PCF generates the final VRU configuration information according to the configuration response and the network side information, and transparently forwards the final VRU configuration information to the VRU terminal through the AMF. Specifically, the AMF transparently forwards the data to the NG-RAN, and then the NG-RAN forwards the data to the VRU terminal.

Based on the embodiment shown in fig. 7, in a variant embodiment of the present application, the V2X application server shown in fig. 7 is also replaced by an AF, i.e. the VRU terminal sends an application-layer request to the AF to request the AF to provide the VRU configuration information discovered by the RSU. The application layer request is also sent by the VRU terminal to the AF through the NG-RAN and the core network.

In an embodiment of the present application, the VRU terminal may also directly obtain the VRU configuration information discovered by the RSU from the PCF, or the PCF directly pushes the information to the VRU terminal, for example, for the process shown in fig. 7, step S701 and step S702 may be omitted, and the PCF directly sends the VRU configuration information discovered by the RSU to the AMF, and then the AMF configures the VRU configuration information discovered by the RSU to the VRU terminal through NAS layer signaling. In this case, optionally, the PCF may first obtain the location information of the VRU terminal, and then provide the VRU terminal with VRU configuration information for discovering the neighboring RSUs, for example, the VRU terminal sends the location information of the VRU terminal to the AMF through the NG-RAN, and then the AMF sends the location information of the VRU terminal to the PCF. Of course, the location information of the VRU terminal can also be provided to the PCF by the NG-RAN without the VRU terminal transmitting. Or the VRU terminal can also send a request message to the PCF, where the request message contains location information of the VRU terminal, and after receiving the request message, the PCF sends VRU configuration information discovered by the RSU to the AMF, and the AMF sends the VRU configuration information discovered by the RSU to the VRU terminal.

In an embodiment of the present application, the VRU configuration information referred in fig. 4 to fig. 7 includes RSU location indication information of adjacent VRU terminals, frequency point and radio resource information of RSUs, and the like. Optionally, the RSU location indication information may be a GNSS location, or a cell ID of a macro cell, or an intersection area of cell IDs of multiple macro cells, or the like; in addition, the RSUs at different positions may use different frequency points to divide different radio resource blocks, and such information can enable the VRU to reduce the process of searching frequency points and the process of reconfiguring radio resources after accessing the RSUs through shared resources.

In an embodiment of the present application, after acquiring the VRU configuration information discovered by the RSU, the VRU terminal may acquire what location has the RSU, and accordingly, may also acquire access information that there is no RSU in a certain traffic location or in the vicinity of a trip location. In the location of the missing RSU, if the VRU terminal still needs to obtain the continuous travel prompting information, the VRU configuration information can also be used by the VRU to change its network access policy, for example, in the location of the missing RSU, the VRU terminal can access to the mobile communication network (e.g. 4G/5G network). Meanwhile, the VRU terminal can be accessed into the mobile communication network before entering the RSU coverage missing position, so that the continuity of the service is ensured, and the reduction of the user experience is avoided.

In an embodiment of the present application, after acquiring the VRU configuration information discovered by the RSU, the VRU terminal may dynamically adjust the network access policy according to the VRU configuration information, capability information of the VRU terminal (e.g., whether the power is sufficient, whether the RSU and the wireless communication network can be accessed simultaneously), VRU service requirements (e.g., the importance degree of the VRU service, etc.), and the like.

In particular, if VRU traffic is important and the VRU terminal is sufficiently charged, the VRU terminal can simultaneously open the PC5 interface (the communication interface with the RSU) and the Uu communication interface (the interface with the access network device) for access to the RSU and the mobile communication network, respectively. In this case, the VRU terminal can select whether to obtain the traffic guidance information through the RSU or the mobile communication network or both at any time. In this case, the V2X application server needs to coordinate and ensure that redundant prompting messages can be avoided, i.e. the same messages are not sent to the VRU terminal both via the RSU and via the mobile communication network.

In an embodiment of the application, if the VRU terminal can meet the continuity requirement of the VRU service by switching the RSU or mobile communication access mode, the PC5 interface and the Uu communication interface do not need to be opened at the same time. In this case, only one interface can be selected to be opened for VRU communication, so as to reduce the energy consumption of the VRU terminal as much as possible.
