[0002] 5G-V2X is the vehicle to everything (V2X) standard of the fifth generation mobile communication technology (5G), also known as NR-V2X. It is a vertical application of 5G in the Internet of Vehicles, which means that the car is connected to everything, and has the advantages of high reliability, high speed, large range, and large bandwidth. Currently, user terminals that support NR-V2X need to request the 5G communication module to configure the policy information of the relevant communication interface by staying in the coverage area of ​​the 5G communication module. However, the 5G communication module has not yet been fully popularized, resulting in a small range of application scenarios for user terminals that support NR-V2X, that is, they can only be used within the signal coverage area of ​​the 5G communication module, which seriously affects the efficient communication of NR-V2X user terminals. Summary of the invention

[0003] The main purpose of the embodiments of the present disclosure is to propose a policy configuration method, system, electronic device and storage medium, aiming to enable user terminals located within the signal coverage range of the fourth generation mobile communication technology (4G) communication module to use an interface for 5G wireless communication to achieve high-speed communication.

[0004] To achieve the above-mentioned purpose, the embodiment of the present disclosure provides a policy configuration method, which is applied to a user terminal, and the user terminal is located within the signal coverage range of a 4G communication module of a fourth-generation mobile communication technology, and the 4G communication module is interconnected with a 5G communication module of a fifth-generation mobile communication technology; it is characterized by comprising:

[0005] The user terminal sends a policy acquisition request to the 4G communication module; the user terminal is integrated with a first communication interface for 5G wireless communication, and the policy acquisition request carries interface information about the first communication interface;

[0006] The 4G communication module sends the received policy acquisition request to the 5G communication module;

[0007] The 5G communication module responds to the policy acquisition request and determines, based on the interface information, whether to issue the initial configuration policy information of the first communication interface; if it is determined that the initial configuration policy information is to be issued, sending the initial configuration policy information to the 4G communication module;

[0008] The 4G communication module determines the calling path information based on the received initial configuration policy information and sends the calling path information to the user terminal;

[0009] The user terminal obtains the target configuration policy information of the first communication interface from the 4G communication module according to the received call path information, and configures the first communication interface according to the target configuration policy information to achieve communication based on the first communication interface.

[0010] To achieve the above-mentioned purpose, the embodiment of the present disclosure further provides a communication system, characterized in that it includes a 4G communication module, a 5G communication module and at least one user terminal located within the signal coverage range of the 4G communication module;

[0011] The user terminal is configured to send a policy acquisition request to the 4G communication module; the user terminal is integrated with a first communication interface for 5G wireless communication, and the policy acquisition request carries interface information about the first communication interface; and, according to the received call path information, obtain target configuration policy information of the first communication interface from the 4G communication module, and configure the first communication interface according to the target configuration policy information to achieve communication based on the first communication interface;

[0014] To achieve the above-mentioned purpose, an embodiment of the present disclosure also provides an electronic device, including: one or more processors; a memory, on which one or more programs are stored, and when the one or more programs are executed by the one or more processors, the one or more processors implement the steps of the aforementioned policy configuration method.

[0016] A policy configuration method, system, electronic device and storage medium provided by the embodiments of the present disclosure are mainly for a user terminal within the signal coverage of a 4G communication module to obtain target configuration policy information for a first communication interface of 5G wireless communication.

[0025] It should be understood that the specific embodiments described herein are only used to explain the present disclosure, and are not used to limit the present disclosure.

[0026] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present disclosure, and have no special meanings. Therefore, "module", "component" or "unit" can be used in a mixed manner.

[0028] For ease of understanding, before introducing the present disclosure, special terms mentioned in the present disclosure are introduced in detail.

[0029] 1. NR-V2X (Vehicle to Everything) is a vehicle-based wireless communication technology that aims to communicate with surrounding vehicles, equipment, and base stations with the vehicle as the center to obtain a series of traffic information such as real-time road conditions, road information, and pedestrian information, in order to improve driving safety, reduce congestion, improve traffic efficiency, and provide in-vehicle entertainment information.

[0030] 2. User Equipment (UE) is an important concept in mobile communications and can run in 3G and 4G networks. UE includes, for example, mobile phones, smart terminals, multimedia devices, streaming media devices, etc. The user terminal in the embodiment of the present disclosure is actually a wireless communication device suitable for supporting NR-V2X, such as a smart car.

[0031] 3. N26 is an interface between the 5G (NR) core network AMF and the 4G (LTE) core network MME to achieve information exchange between 5G (NR) and 4G (LTE). As the 5G core network, AMF (Access AND mobility Management Function) is mainly responsible for registration management, connection management, access management, mobility management, and various functions related to security and access management and authorization. As the 4G core network, MME (Mobile Managenment Entity) is mainly responsible for registration management, connection management, access management, mobility management, and various functions related to security and access management and authorization.

[0032] 4. Extensible Markup Language (XML), a subset of the standard general markup language, can be used to mark data and define data types. It is a source language that allows users to define their own markup language. XML is a standard general markup language with good extensibility, separation of content and form, strict syntax requirements, and good value preservation.

[0033] 5. Direct communication interface NR-PC5 is a short-distance direct communication interface that can realize the communication between vehicles, people and roads. Regardless of whether there is network coverage, the PC5 interface can be used for V2X communication. NR-PC5 can achieve low latency and improve reliability under non-line-of-sight conditions.

[0034] 6. PCF (Policy Control Function) is a policy control functional entity that supports a unified policy framework and manages network behavior, provides policy rules to network entities, and accesses subscription information of the unified data repository (UDR).

[0035] 7. In the Long Term Evolution (LTE) network (also known as 4G network), due to the evolution relationship, the access network part is called the Evolved UMTS Terrestrial Radio Access Network (Evolved UMTS Terrestrial Radio Access Network, E-UTRAN), which is the mobile communication wireless network in LTE.

[0036] In the related art, since the 5G communication module has not yet been fully popularized, the application scenarios of user terminals supporting NR-V2X are relatively small, which seriously affects the efficient communication of NR-V2X user terminals. At present, pre-configuration parameters can be stored in the 4G communication module in advance to support the configuration of related interfaces. However, most 4G communication modules pre-store relevant interface configuration strategies for 4G communications, and rarely pre-store relevant interface configuration strategies for 5G communications to occupy resources. Therefore, the local storage of the 4G communication module is likely to not contain the pre-configuration parameters to be accessed by the user terminal. In this way, user terminals that are not within the coverage of the 5G communication module cannot access the configuration strategy that supports NR-V2X.

[0037] In view of this, the embodiment of the present disclosure provides a policy configuration method, which is mainly for a user terminal within the signal coverage of a 4G communication module to obtain target configuration policy information for the first communication interface of 5G wireless communication, and to achieve long-distance data transmission between the 4G communication module and the 5G communication module through close-range information interaction between the user terminal and the 4G communication module, and to establish an interconnection relationship between the 4G communication module and the 5G communication module, so as to obtain the target configuration policy information of the first communication interface and achieve high-speed communication. At the same time, the 4G communication module only sends the call path information of the target configuration policy information to the user terminal, and the data volume of the call path information is much smaller than the target configuration policy information, which can save the communication bandwidth between the user terminal and the 4G communication module and improve the configuration efficiency.

[0038] For ease of understanding, the embodiment of the present disclosure first introduces a policy configuration method in detail. The execution subject of the policy configuration method provided by the present disclosure may be a communication system, which at least includes a 4G communication module, a 5G communication module and at least one user terminal within the signal coverage range of the 4G communication module.

[0039] The policy configuration method provided in the present disclosure is mainly applied to wireless communication of user terminals, wherein the user terminals are, for example, UEs, and are mainly located within the signal coverage of 4G communication modules. The 4G communication modules are interconnected with the 5G communication modules, and the specific interconnection method may be, for example, interconnected by using N26 interfaces.

[0040] The process of the user terminal acquiring the target configuration policy information is mainly in the registration stage of the user terminal. Figure 1a A schematic diagram of information interaction between modules in the policy configuration process provided by the embodiment of the present disclosure, such as Figure 1a As shown, it includes steps S11 to S15, wherein:

[0041] S11. The user terminal sends a policy acquisition request to the 4G communication module.

[0042] The user terminal is integrated with a first communication interface for 5G wireless communication, and the policy acquisition request carries interface information about the first communication interface.

[0043] Exemplarily, the first communication interface may include but is not limited to an NR-PC5 interface. In the embodiment of the present disclosure, when the user terminal uses the NR-PC5 interface for wireless communication, high-speed communication can be achieved. The interface information of the NR-PC5 interface includes, for example, relevant information that can characterize the identity of the NR-PC5 interface.

[0044] For example, the user terminal can be interconnected with the 4G communication module through the air interface. The full name of the air interface is "air interface", which is a figurative term and is the wireless transmission specification between the base station and the UE. It defines the use frequency, bandwidth, access timing, coding method and handover of each wireless channel. For example, in wireless communication, the UE and the base station are connected to each other through the air interface.

[0045] S12. The 4G communication module sends the received policy acquisition request to the 5G communication module.

[0046] For example, Figure 1b A schematic diagram of the specific information interaction of each module in the policy configuration process provided by the embodiment of the present disclosure, such as Figure 1b As shown, the 4G communication module can be, for example, a 4G communication system integrating a second management unit and a second control unit, such as a 4G base station; wherein the second management unit is, for example, a 4G (LTE) core network MME, and the second control unit is, for example, a V2X control function (V2X control function) unit, and the V2X control function is mainly to provide the UE with the necessary V2X configuration strategy to perform related network actions to realize V2X communication.

[0047] For example, Figure 1b As shown, the 5G communication module can be, for example, a 5G communication system integrated with a first management unit and a first control unit, such as a 5G base station. Among them, the first management unit is, for example, a 5G (NR) core network AMF, and the first control unit is, for example, a policy control function (PCF). PCF can be understood as a policy control function entity, which can support a unified policy framework and manage network behavior, and provide configuration policies to network entities.

[0048] For step S12, specifically, Figure 1bAs shown, the MME responds to the received policy acquisition request and sends the policy acquisition request to the AMF when parsing the policy acquisition request to carry the interface information of the first communication interface. Exemplarily, the MME and the AMF can be interconnected using the N26 interface.

[0049] S13. The 5G communication module responds to the policy acquisition request and determines whether to send the initial configuration policy information of the first communication interface based on the interface information.

[0050] Specifically, Figure 1b As shown, AMF sends the received policy acquisition request to PCF; PCF responds to the policy acquisition request and determines whether to send the initial configuration policy information of NR-PC5 based on the interface information.

[0051] PCF is a policy control function entity, so it controls and manages the configuration policies of various interfaces. The configuration policy is also the configuration parameter of the interface in the user terminal. After the user terminal obtains the configuration policy and configures the interface using the configuration policy, the user terminal can realize communication using the interface. In other words, if the user terminal does not obtain the interface configuration policy, it cannot realize communication using the interface.

[0052] PCF controls and manages the configuration policies of different interfaces, responds to policy acquisition requests, and parses the interface information carried in the policy acquisition request. When the interface information indicates an NR-PC5 interface, it determines whether to issue the initial configuration policy information of the NR-PC5 interface according to the interface information. The initial configuration policy information is at least part of the NR-V2X configuration parameters that support UE to implement wireless communication on the NR-PC5 interface.

[0053] For step PCF responds to the policy acquisition request and determines whether to issue the initial configuration policy information of NR-PC5 based on the interface information. There are several different judgment methods as follows:

[0054] In a possible implementation, the policy acquisition request also carries device information about the user terminal. The 5G communication module includes a first management unit and a first control unit; the first management unit is AMF and the first control unit is PCF as an example for explanation. Figure 2 A flowchart of determining whether to issue the initial configuration policy information of NR-PC5 is provided in an embodiment of the present disclosure, such as Figure 2 As shown, it includes steps S21 to S24, and the specific execution subject is PCF, wherein:

[0055] S21. Respond to a policy acquisition request.

[0056] S22, detecting whether initial configuration policy information matching the interface information is stored, if so, executing step S23; if not, executing step S24.

[0057] S23: If it is determined that initial configuration policy information matching the interface information is stored, determine to send the initial configuration policy information.

[0058] S24. If it is determined that the initial configuration policy information matching the interface information is not stored, refuse to issue the initial configuration policy information and feedback a rejection instruction to the AMF.

[0059] By using the judgment method of the S21-S24 interface information calibration, the situation of chaotic policy matching can be avoided and orderly policy configuration can be achieved.

[0060] In another possible implementation, the policy acquisition request also carries device information about the user terminal. The 5G communication module includes a first management unit and a first control unit; the first management unit is AMF and the first control unit is PCF as an example for explanation. Figure 3 Another flowchart for determining whether to issue the initial configuration policy information of NR-PC5 is provided in the embodiment of the present disclosure, such as Figure 3 As shown, it includes steps S31 to S36, and the specific execution subject is PCF, wherein:

[0061] S31. Respond to a policy acquisition request.

[0062] S32, detecting whether the user terminal indicated by the device information has application authority, if so, executing step S33; if not, executing step S36.

[0063] The device information includes, for example, relevant information that can characterize the UE identity. The application permission includes any right that the user terminal is allowed to obtain the configuration policy information of NR-PC5, such as the permission granted by the operator to support NR-V2X, etc.

[0064] S33. When it is determined that the user terminal has the application authority, check whether initial configuration policy information matching the interface information is stored. If so, execute step S34; if not, execute step S35.

[0065] S34: If it is determined that initial configuration policy information matching the interface information is stored, determine to send the initial configuration policy information.

[0066] S35. If it is determined that the initial configuration policy information matching the interface information is not stored, refuse to issue the initial configuration policy information and feedback a rejection instruction to the AMF.

[0067] S36: If it is determined that the user terminal does not have application authority, refuse to issue the initial configuration policy information and feedback a rejection instruction to the AMF.

[0068] Through the above S31 to S36 combined with the judgment method of UE authority calibration and interface information calibration, the PCF can more accurately control the delivery of initial configuration policy information and realize orderly policy configuration.

[0069] Exemplarily, in the case of refusing to send the initial configuration policy information in the above S24, S35 or S36, the AMF sends the received feedback rejection instruction to the MME; in response to the rejection instruction, the MME may send configuration failure information to the UE, or send the E-UTRAN configuration policy for 4G wireless communication saved by the V2X control function to the UE.

[0070] S14. When the 5G communication module determines to send the initial configuration policy information, the 5G communication module sends the initial configuration policy information to the 4G communication module.

[0071] Specifically, Figure 1b As shown, when the PCF determines to send the initial configuration policy information, the PCF sends the initial configuration policy information to the AMF; the AMF sends the received initial configuration policy information to the MME.

[0072] S15. The 4G communication module determines the calling path information based on the received initial configuration policy information and sends it to the user terminal.

[0073] Exemplarily, the call path information may be, for example, an address of an access configuration policy.

[0074] The 4G communication module includes a second management unit and a second control unit; the second management unit is MME, and the second control unit is V2X control function. Specifically, the MME determines the call path information based on the received initial configuration policy information and sends it to the UE.

[0075] In a possible implementation, the MME generates target configuration policy information based on the initial configuration policy information using a preset algorithm, and sends the target configuration policy information to the V2X control function for storage, and generates calling path information of the target configuration policy information and sends it to the user terminal.

[0076] In another possible implementation, considering the memory space of the V2X control function, in order to avoid repeated storage of the V2X control function, the MME may first determine the storage status of the configuration policy of the V2X control function, and then determine the call path information. Figure 1b As shown, the MME determines whether the V2X control function stores initial configuration policy information based on a pre-stored policy table; the policy table includes information on the configuration policy stored by the V2X control function; when it is determined that the V2X control function does not store the initial configuration policy information, based on the initial configuration policy information, a preset algorithm is used to generate target configuration policy information and send it to the V2X control function; and, call path information of the target configuration policy information is generated.

[0077] The initial configuration policy information may be at least part of the NR-V2X configuration parameters. The target configuration policy information is the NR-V2X configuration parameters that support the UE to implement wireless communication on the NR-PC5 interface, which is a complete configuration parameter. Therefore, in the process of determining whether the V2Xcontrol function stores the initial configuration policy information, the MME specifically detects whether there is target configuration policy information corresponding to the initial configuration policy information in the policy table, and the interface information of the initial configuration policy information and the corresponding target configuration policy information are consistent.

[0078] Generate calling path information of target configuration policy information. Specifically, when it is determined that the V2X control function does not store initial configuration policy information, the calling path information of the target configuration policy information can be automatically generated according to a preset address generation algorithm.

[0079] Alternatively, the policy table records the target configuration policy information and the call path information for accessing the target configuration policy information, such as the V2X control function address. When it is determined that the V2X control function does not store the initial configuration policy information, the call path information corresponding to the target configuration policy information with a lower access frequency in the policy table can be sent to the UE as the call path information to be sent. If this multiplexing method is adopted, the target configuration policy information with a lower access frequency in the V2Xcontrol function needs to be replaced with the target configuration policy information corresponding to the NR-PC5 interface generated by the MME.

[0080] In this implementation mode, the MME uses the policy table to monitor the configuration policy information in the V2X control function, thereby avoiding the situation where the V2X control function repeatedly stores the same configuration policy to a large extent, and saving the memory space of the V2X control function.

[0081] In some embodiments, the MME uses a preset algorithm based on the initial configuration policy information to generate target configuration policy information and send it to the V2X control function, which may specifically include the MME using a preset markup language to generate a first enablement field; adding the first enablement field to the initial configuration policy information to obtain the target configuration policy information; and sending the target configuration policy information to the second control unit.

[0082] Exemplarily, the preset markup language is XML, for example, and the first enabled field can be, for example, a "served by NR" and "not served by NR" field. Specifically, the MME can generate the "served by NR" and "not served by NR" fields by using XML, and add the "served by NR" and "not served by NR" fields to the initial configuration policy information to obtain the target configuration policy information; thereafter, the MME sends the target configuration policy information to the V2X control function for storage, so that the user terminal can obtain the target configuration policy information from the V2X control function according to the calling path information of the target configuration policy information.

[0083] In some embodiments, the policy table records the target configuration policy information and the call path information for accessing the target configuration policy information, such as the V2X control function address. When the MME detects that the target configuration policy information corresponding to the initial configuration policy information exists in the policy table, it determines that the V2X control function stores the initial configuration policy information, obtains the call path information of the target configuration policy information from the policy table, and sends it to the user terminal. Afterwards, the user terminal can obtain the target configuration policy information from the V2X control function according to the call path information of the target configuration policy information.

[0084] For example, Figure 4 A flowchart for determining call path information provided by an embodiment of the present disclosure, such as Figure 4 As shown, steps S41 to S43 are included, and the specific execution subject is the MME, wherein:

[0085] S41. According to the pre-stored strategy table, determine whether the second control unit stores initial configuration strategy information. If not, execute step S42; if yes, execute step S43.

[0086] Among them, the MME records a policy table, which can be updated at any time. The policy table includes information about the configuration policy stored by the V2X control function at the current moment. If the configuration policy stored in the V2X control function changes, the V2X control function will send an instruction to the MME to enable the MME to update the policy table. That is, when it is determined that the second control unit does not store the initial configuration policy information, the policy table is updated using the initial policy configuration information.

[0087] Specifically, after receiving the initial configuration policy information, the MME detects whether there is target configuration policy information matching the initial configuration policy information in the policy table. If so, it is determined that the V2X control function stores the initial configuration policy information; otherwise, it is determined that the V2X control function does not store the initial configuration policy information.

[0088] S42: if it is determined that the second control unit does not store the initial configuration policy information, based on the initial configuration policy information, using a preset algorithm, generate target configuration policy information and send it to the second control unit; and generate calling path information of the target configuration policy information.

[0089] Exemplarily, when it is determined that the V2X control function does not store the initial configuration policy information, the V2X control function address of the target configuration policy information can be automatically generated according to a preset address generation algorithm.

[0090] S43: When it is detected that the policy table contains target configuration policy information corresponding to the initial configuration policy information, determine that the second control unit stores the initial configuration policy information, obtain the calling path information of the target configuration policy information from the policy table, and send it to the user terminal.

[0091] It should be noted that the call path information, for example, the access V2X control function address, has a much smaller data volume than the target configuration policy information. Therefore, the MME only sends the V2X control function address to the UE, which can save the communication bandwidth between the UE and the MME and improve the configuration efficiency.

[0092] S16. The user terminal obtains target configuration policy information of the first communication interface from the 4G communication module according to the received call path information, and configures the first communication interface according to the target configuration policy information to implement communication based on the first communication interface.

[0093] Specifically, Figure 1b As shown, the 4G communication module includes a second management unit and a second control unit; the user terminal obtains the target configuration policy information from the second control unit according to the calling path information of the target configuration policy information. For example, the UE accesses the V2X control function according to the V2X control function address to obtain the target configuration policy information.

[0094] A policy configuration method provided by an embodiment of the present disclosure enables the UE to obtain the configuration parameters for communicating on the NR-PC5 interface allocated by the network side within the 4G network coverage area, thereby expanding the actual application scenarios of the UE and breaking the limitation of being restricted by the 5G network coverage area.

[0095] In the prior art, when a UE accesses the V2X control function in a 4G base station and requests to obtain target configuration policy information, if other user terminals (for example, multiple UEs located within the signal coverage of the 4G base station, in addition to the UEs that have obtained the target configuration policy information) also want to access the V2X control function in the 4G base station and request to obtain the configuration parameters of the NR-PC5 interface, if many other user terminals access the same V2X control function address at the same time, then the address may cause congestion, thereby reducing communication performance.

[0096] In this regard, after the user terminal obtains the target configuration policy information from the 4G communication module in step S16, the user terminal can also broadcast a shared configuration message to achieve resource sharing with other user terminals. Specifically, other user terminals respond to the shared configuration message and feedback a request for sharing instruction to the user terminal; other user terminals are terminals that are interconnected with the user terminal and have not obtained the target configuration policy information of the first communication interface; other user terminals are located within the signal coverage of the 4G communication module; the user terminal responds to the request for sharing instruction and sends the target configuration policy information of the first communication interface to other user terminals that feedback the request for sharing instruction; other user terminals receive the target configuration policy information and configure the first communication interface according to the target configuration policy information to achieve communication based on the first communication interface.

[0097] Figure 5 The information interaction diagram of the sharing strategy provided by the embodiment of the present disclosure is as follows: Figure 5As shown, it includes UE1 that has obtained the target configuration policy information, and UE2 and UE3 that have not obtained the target configuration policy information. Specifically, UE1 obtains the target configuration policy information from PCF according to the specific process of steps S11 to S16 above, and saves it locally. UE2 and UE3 both use the default configuration interface to wait for receiving the target configuration policy information. UE1 uses the default configuration interface to broadcast the shared configuration message. Here, UE1 can interact with other user terminals (UE2 and / or UE3) in a unicast manner. The default configuration interface here can be, for example, a PC5 interface or other communication interface. When there is a request to obtain the NP-PC5 configuration policy, other user terminals (UE2 and / or UE3) feedback a request sharing instruction. In response to the request reception instruction fed back by other user terminals (UE2 and / or UE3), UE1 again uses the default configuration interface to send the NP-PC5 target configuration policy information to the corresponding other user terminals (UE2 and / or UE3). Afterwards, other user terminals (UE2 and / or UE3) receive the target configuration policy information and configure NP-PC5 according to the target configuration policy information to achieve communication based on the first communication interface. Afterwards, the newly configured NP-PC5 can be used to establish unicast or multicast communication between user terminals to avoid congestion on the default configured communication parameters and improve communication performance.

[0098] In the embodiment of the present disclosure, other user terminals do not need to perform steps S11 to S16, and can synchronously obtain the target configuration policy information of NP-PC5 by broadcasting the shared configuration message through UE1, thereby effectively avoiding congestion and enhancing communication reliability.

[0099] Exemplarily, the sharing range between the user terminal and other user terminals is, for example, between 0 and 1000 m, to ensure transmission accuracy when environmental conditions permit. For example, before vehicles need to drive in formation (which can be understood as the registration stage), they can be gathered in a certain range for synchronization configuration strategy.

[0100] In some embodiments, after other user terminals obtain the target configuration policy information from the user terminal, the other user terminals can act as new shared devices and broadcast shared configuration messages through the first communication interface to achieve policy acquisition for UEs in a wider range that have not obtained the target configuration policy information.

[0101] The above is a detailed description of a policy configuration method provided by an embodiment of the present disclosure.
