[0039] Figure 1This diagram illustrates a block diagram of a wireless communication system applicable to embodiments of this application. The wireless communication system includes a first terminal 11 and a network-side device 12. The first terminal 11 can be a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), handheld computer, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), augmented reality (AR) / virtual reality (VR) device, robot, wearable device, vehicle-mounted device (VUE), pedestrian first terminal (PUE), smart home (home devices with wireless communication capabilities, such as refrigerators, televisions, washing machines, or furniture), game console, personal computer (PC), ATM, or self-service machine, etc. Wearable devices include: smartwatches, smart bracelets, smart headphones, smart glasses, smart jewelry (smart bracelets, smart chains, smart rings, smart necklaces, smart anklets, smart anklets, etc.), smart wristbands, smart clothing, etc. It should be noted that the specific type of the first terminal 11 is not limited in this application embodiment. Network-side equipment 12 may include access network equipment or core network equipment. Access network equipment 12 may also be referred to as radio access network equipment, radio access network (RAN), radio access network function, or radio access network unit.

The base station is not limited to specific technical terms. It should be noted that in this application embodiment, only a base station in an NR system is used as an example for description, and the specific type of base station is not limited.

[0040] Device-to-device (D2D) communication refers to data transmission that does not go through a base station, allowing one mobile terminal device to communicate directly with another. Originating in the 4G era, D2D is known as LTE Proximity Services (ProSe) technology. It is a short-range communication technology based on the 3GPP communication system, primarily comprising two functions: Direct discovery, which allows a terminal to discover nearby terminals with which it can directly connect; and Direct communication, which enables data exchange with these nearby terminals.

[0041] In the 4G era, D2D communication was mainly used only in the field of public safety. With the advent of the 5G era, due to the rise of Internet of Things applications such as vehicle-to-everything (V2X), autonomous driving, and wearable devices, 5G ProSe technology has emerged.

[0042] 5G ProSe direct communication allows terminals to interact with surrounding terminals. This data interaction can occur either through the traditional UE1-5G core network (5GC)-Application Server-UE2 path, or through a direct communication mechanism based on the PC5 link.

[0043] In the 5G ProSe direct communication scenario, if the direct communication is triggered by a certain application of the terminal, the network-side device will configure a mapping rule between the path preference and the ProSe application or application identifier (hereinafter referred to as the first mapping rule) for the terminal.

[0044] The first mapping rule is a mapping list containing several mapping rules. Each mapping rule can contain one of the following: the mapping relationship between a certain application identifier and path preference (referred to as the first type of mapping relationship), or the mapping relationship between all applications and path preference (referred to as the second type of mapping relationship).

[0045] The terminal will select the path preference based on the first mapping rule configured on the network side device.

[0046] If the application also has path preferences, how to indicate these preferences to the terminal? Currently, related technologies can only achieve this through policy updates on the network-side device. That is, the network-side device updates the first mapping rule according to the application layer's requirements, includes the second type of mapping relationship in the first mapping rule, and sends it to the terminal. This incurs certain signaling overhead for the terminal. Furthermore, if the terminal is configured with both the first and second types of mapping relationships, it may need to match all path preference mapping rules to determine the application's path preference. This is unfriendly to the terminal because, with a large number of path preference mapping rules, the terminal must perform some unnecessary matching to finally determine a path preference, resulting in wasted computing resources, high computational complexity, and long user waiting times.

[0047] To address the aforementioned problems, embodiments of this application provide a path preference determination method. The path preference determination method provided by these embodiments will be described in detail below with reference to the accompanying drawings, through some examples and application scenarios.

[0048] Figure 2 This is one of the flowcharts illustrating the path preference determination method provided in the embodiments of this application, such as... Figure 2 As shown, the path preference determination method includes the following steps:

[0049] Step 200: The first terminal acquires the first information;

[0050] It should be noted that the first piece of information is used to indicate route preferences.

[0051] Path preference refers to the preferred path for communication between terminals.

[0052] Optionally, the path preference includes at least one of the following: preference for PC5, preference for Uu, or no preference.

[0053] If the path preference is PC5, then the data flow uses the PC5 mechanism, that is, by establishing a PC5 link between the first terminal and the second terminal, data is transmitted through the PC5 link.

[0054] If the path preference is Uu, the data flow uses the Uu mechanism, that is, the first terminal establishes the first PDU session and sends it to the application server through the data plane; the application server sends downlink data to the second terminal through the second PDU session established by the second terminal, thereby realizing communication between the first terminal and the second terminal.

[0055] If the path preference is no preference, the data flow direction is determined according to the terminal implementation. The PC5 mechanism or the Uu mechanism can be used to realize the communication between the first terminal and the second terminal.

[0056] Optionally, obtaining can be understood as acquiring from configuration, receiving, receiving after a request, acquiring through self-learning, inferring from unreceived information, or acquiring after processing received information. The specific method can be determined according to actual needs, and this application embodiment does not limit it.

[0057] Step 201: The first terminal determines the path preference of the target application based on the first information.

[0058] After the first terminal obtains the first information, it can then determine the path preference of the target application based on the first information.

[0059] In this embodiment, the terminal obtains first information and determines the path preference of the target application based on the first information. Compared with instructing the terminal on the path preference of the application through policy updates of network-side devices, this can save terminal signaling overhead and computing resources, reduce the computational complexity of the terminal, and shorten the user's waiting time.

[0060] In some embodiments, the first information includes at least one of the following:

[0061] a) First indication information, wherein the first indication information is used to indicate the path preference of the target application;

[0062] In one embodiment, the first terminal acquires first information, including:

[0063] The ProSe layer of the first terminal obtains the first indication information sent by the application layer or upper layer of the first terminal.

[0064] Figure 3 This is an interactive schematic diagram of the path preference determination method provided in the embodiments of this application.

[0065] It is understandable that the path preference of the target application can be indicated to the first terminal through the inter-layer interaction between the ProSe layer and the application layer.

[0066] Furthermore, after the ProSe layer of the first terminal obtains the first instruction information, it determines the path preference of the target application based on the first instruction information.

[0067] If the first indication information indicates that the target application's path preference is PC5, then the first terminal uses the 5G ProSe direct communication mechanism on PC5 to communicate with the second terminal. If the first indication information indicates that the target application's path preference is Uu, then the first terminal uses the Uu mechanism to communicate with the second terminal. If the first indication information indicates that the target application's path preference is no preference, then the mechanism used depends on the UE implementation. For example, the UE can select a path based on the previous path of the target application.

[0068] b) A path preference mapping rule list, which includes path preference mapping rules and priority information corresponding to the path preference mapping rules;

[0069] Each of the path preference mapping rules is used to indicate a path preference.

[0070] In some embodiments, each of the path preference mapping rules includes a mapping relationship between a path preference and an application, or a mapping relationship between a path preference and an application identifier, or a mapping relationship between a path preference and all applications.

[0071] Optionally, the path preference mapping rule list includes a first type of mapping relationship and a second type of mapping relationship;

[0072] The first type of mapping relationship is the mapping relationship between a specific application and path preferences; the second type of mapping relationship is the mapping relationship between all applications and path preferences.

[0073] In other words, the mapping relationship between a path preference and an application, or between a path preference and an application identifier, can be called a first-type mapping relationship. The mapping relationship between a path preference and all applications can be called a second-type mapping relationship.

[0074] It's important to note that the first type of mapping should have a higher priority than the second type. This is easy to understand because the second type of mapping essentially defines a default mapping for all applications; for example, all applications default to preferring PC5. When an application is additionally configured with a path preference (the first type of mapping), then the priority of this additional configuration (the first type of mapping) should be higher than its default configuration (the second type of mapping).

[0075] In this embodiment, the path preference mapping rule list includes not only the path preference mapping rules themselves, but also priority information corresponding to those rules. It can be understood that by using the priority information of the path preference mapping rules, the terminal can more quickly match the path preferences of the target application, saving terminal computing resources and reducing computational complexity.

[0076] Optionally, each of the path preference mapping rules further includes a second indication field, which is used to indicate whether the path preference mapping rule contains an application identifier;

[0077] When the second indication field indicates that the path preference mapping rule does not contain an application identifier, the path preference mapping rule indicates the mapping relationship between a path preference and all applications; that is, the path preference mapping rule reflects a second type of mapping relationship. For example, the path preference mapping rule is preference PC5, which does not contain any application identifier, indicating that the path preference for all applications is preference PC5.

[0078] When the second indication field is used to indicate that the path preference mapping rule contains an application identifier, the path preference mapping rule is used to indicate the mapping relationship between a path preference and an application, or the mapping relationship between a path preference and an application identifier.

[0079] In some embodiments, the first terminal acquires first information, including:

[0080] The first terminal receives the path preference mapping rule list sent by the network-side device.

[0081] The network-side device generates a list of path preference mapping rules based on the path preferences provided by the application server, and then sends the list of path preference mapping rules to the terminal.

[0082] Sending can also be understood as configuration.

[0083] Furthermore, the first terminal determines the path preference of the target application based on the first information, including:

[0084] The first terminal obtains the path preference that matches the identifier of the target application based on the path preference mapping rule list and the priority information.

[0085] The path preference mapping rule list includes priority information and can be implemented in the following two ways:

[0086] In one embodiment, the path preference mapping rule list includes at least one path preference mapping rule sorted according to the priority information.

[0087] In other words, the path preference mapping rule list sent from the network-side device to the first terminal is already sorted. This means that the network-side device prioritized the path preference mapping rules when encoding the list. Once the terminal successfully matches a rule, it can stop matching other path preference mapping rules. This saves terminal computing resources, reduces computational complexity, and shortens user waiting time.

[0088] In one implementation, each of the path preference mapping rules has a first indication field, which is used to indicate the priority information.

[0089] That is, each path preference mapping rule in the path preference mapping rule list sent by the network-side device to the first terminal contains the priority information of that path preference mapping rule.

[0090] Optionally, the terminal first matches the path preference mapping rule with the highest priority, then matches the path preference mapping rule with the highest priority, and so on.

[0091] By incorporating new priority information into the encoding strategy of existing mapping rules, the priority of each path-preferred mapping rule is reflected. Another advantage of this approach is that it allows for backward compatibility with more potential future path selection strategies.

[0092] In some embodiments, at least one application corresponds to one or more path preference mapping rules, or at least one application identifier corresponds to one or more path preference mapping rules.

[0093] It is understandable that at least one application can correspond to one path preference mapping rule, or it can correspond to multiple path preference mapping rules.

[0094] At least one application identifier can correspond to one path preference mapping rule or multiple path preference mapping rules.

[0095] In some embodiments, when at least one application corresponds to multiple path preference mapping rules, or when at least one application identifier corresponds to multiple path preference mapping rules, the priority of the path preference corresponding to the at least one application or application identifier in different path preference mapping rules is different.

[0096] When an application or application identifier corresponds to M path preference mapping rules, the application or application identifier has different priorities among the M path preference mapping rules. M is a positive integer greater than 1.

[0097] It is understandable that for the same application (application identifier), the priority of that application (application identifier) ​​is different in each path preference mapping rule. Network-side devices can configure multiple path preference mapping rules for the same application.

[0098] Optionally, the priority information value is a positive integer between 0 and 255, where the larger the priority value, the lower the priority of the corresponding path preference mapping rule.

[0099] In some embodiments, after determining the path preference of the target application, the method further includes:

[0100] When the target application's path preference is PC5, the first terminal uses the ProSe direct communication mechanism on PC5 to communicate with the second terminal.

[0101] When the path preference of the target application is Uu, the first terminal uses the Uu mechanism to communicate with the second terminal;

[0102] When the target application has no path preference, the first terminal communicates with the second terminal based on the implementation of the first terminal.

[0103] Figure 4 A second flowchart illustrating the path preference determination method provided in this application includes:

[0104] Step 400: The network-side device generates a list of path preference mapping rules based on the path preferences provided by the application server;

[0105] Optionally, the network-side device generates a list of path preference mapping rules based on path preferences provided by the AF or application server.

[0106] Step 401: The network-side device sends the path preference mapping rule list to the terminal;

[0107] The path preference mapping rule list includes path preference mapping rules and priority information corresponding to the path preference mapping rules. Each path preference mapping rule is used to indicate a path preference.

[0108] Optionally, the path preference includes at least one of the following: preference for PC5, preference for Uu, or no preference.

[0109] If the path preference is PC5, then the data flow uses the PC5 mechanism, that is, by establishing a PC5 link between the first terminal and the second terminal, data is transmitted through the PC5 link.

[0110] If the path preference is Uu, the data flow uses the Uu mechanism, that is, the first terminal establishes the first PDU session and sends it to the application server through the data plane; the application server sends downlink data to the second terminal through the second PDU session established by the second terminal, thereby realizing communication between the first terminal and the second terminal.

[0111] If the path preference is no preference, the data flow direction is determined according to the terminal implementation. The PC5 mechanism or the Uu mechanism can be used to realize the communication between the first terminal and the second terminal.

[0112] In this embodiment of the application, the path preference mapping rule list sent by the network-side device to the terminal includes priority information, which enables the terminal to match path preferences more quickly.

[0113] Optionally, each of the path preference mapping rules includes a mapping relationship between a path preference and an application, or a mapping relationship between a path preference and an application identifier, or a mapping relationship between a path preference and all applications.

[0114] In some embodiments, the list of path preference mapping rules includes at least one path preference mapping rule sorted according to the priority information.

[0115] In other words, the path preference mapping rule list sent from the network-side device to the first terminal is already sorted. This means that the network-side device prioritized the path preference mapping rules when encoding the list. Once the terminal successfully matches a rule, it can stop matching other path preference mapping rules. This saves terminal computing resources, reduces computational complexity, and shortens user waiting time.

[0116] Optionally, the network-side device generates a list of path preference mapping rules based on the path preferences provided by the application server, including:

[0117] The network-side device obtains at least one path preference mapping rule based on the path preferences provided by the application server;

[0118] Configure the priority information corresponding to each of the path preference mapping rules;

[0119] The path preference mapping rule is sorted according to the priority information corresponding to each path preference mapping rule to obtain the path preference mapping rule list.

[0120] In some embodiments, each of the path preference mapping rules has a first indication field, which is used to indicate the priority information.

[0121] In other words, each path preference mapping rule in the list of path preference mapping rules sent from the network-side device to the first terminal contains priority information. Therefore, the terminal will first match the path preference mapping rule with the highest priority, then match the path preference mapping rule with the second highest priority, and so on.

[0122] By incorporating new priority information into the encoding strategy of existing mapping rules, the priority of each path-preferred mapping rule is reflected. Another advantage of this approach is that it allows for backward compatibility with more potential future path selection strategies.

[0123] Optionally, the network-side device generates a list of path preference mapping rules based on the path preferences provided by the application server, including:

[0124] The network-side device obtains at least one path preference mapping rule based on the path preferences provided by the application server;

[0125] Determine the priority information corresponding to each of the path preference mapping rules;

[0126] The priority information corresponding to each of the path preference mapping rules is written into the first indicator field of each of the path preference mapping rules to obtain the path preference mapping rule list.

[0127] Optionally, at least one application corresponds to one or more path preference mapping rules, or at least one application identifier corresponds to one or more path preference mapping rules.

[0128] It is understandable that at least one application can correspond to one path preference mapping rule, or it can correspond to multiple path preference mapping rules.

[0129] At least one application identifier can correspond to one path preference mapping rule or multiple path preference mapping rules.

[0130] Optionally, when at least one application corresponds to multiple path preference mapping rules, or when at least one application identifier corresponds to multiple path preference mapping rules, the priority of the path preference corresponding to the at least one application or application identifier in different path preference mapping rules is different.

[0131] When an application or application identifier corresponds to M path preference mapping rules, the application or application identifier has different priorities among the M path preference mapping rules. M is a positive integer greater than 1.

[0132] It is understandable that for the same application (application identifier), the priority of that application (application identifier) ​​is different in each path preference mapping rule. Network-side devices can configure multiple path preference mapping rules for the same application.

[0133] Optionally, the priority information value is a positive integer between 0 and 255, where the larger the priority value, the lower the priority of the corresponding path preference mapping rule.

[0134] In this embodiment of the application, the path preference mapping rule list sent by the network-side device to the terminal includes priority information, which enables the terminal to match path preferences more quickly, saves terminal computing resources, reduces terminal computing complexity, and saves user waiting time.

[0135] Optionally, the application server sends path preferences to the terminal or network-side device.

[0136] In one embodiment, the application server sends a path preference to the application layer or upper layer of the terminal, and the application layer or upper layer of the terminal sends a first path indication information to the ProSe layer of the terminal, the first indication information indicating the path preference.

[0137] In one implementation, the application server sends path preferences to the network-side device. Based on the path preferences provided by the application server, the network-side device generates a path preference mapping rule list and sends the path preference mapping rule list to the terminal.

[0138] The path preference determination method provided in this application can be executed by a path preference determination device. This application uses the example of a path preference determination device executing the method to illustrate the path preference determination device provided in this application.

[0140] The first acquisition unit 510 is used to acquire first information;

[0141] The first determining unit 520 is used to determine the path preference of the target application based on the first information.

[0142] In this embodiment of the application, by obtaining the first information and determining the path preference of the target application based on the first information, compared with indicating the path preference of the application to the terminal through policy updates of the network-side device, terminal signaling overhead and computing resources can be saved, the computing complexity of the terminal can be reduced, and the user's waiting time can be shortened.

It is understood that the aforementioned modem processor may also not be integrated into processor 810.

[0194] The processor 810 is used to acquire the first information;

[0195] Based on the first information, the path preference of the target application is determined.

[0196] In this embodiment of the application, by obtaining the first information and determining the path preference of the target application based on the first information, compared with indicating the path preference of the application to the terminal through policy updates of the network-side device, terminal signaling overhead and computing resources can be saved, the computing complexity of the terminal can be reduced, and the user's waiting time can be shortened.

[0197] Optionally, the first information includes at least one of the following:

[0198] First indication information, the first indication information being used to indicate the path preference of the target application;

[0199] A path preference mapping rule list, which includes path preference mapping rules and priority information corresponding to the path preference mapping rules;

[0200] Each of the path preference mapping rules is used to indicate a path preference.

[0201] In this embodiment, the path preference mapping rule list includes not only the path preference mapping rules themselves, but also priority information corresponding to those rules. Based on this priority information, the terminal can more quickly match the path preferences of the target application, saving terminal computing resources and reducing computational complexity.

[0202] Optionally, each of the path preference mapping rules includes a mapping relationship between a path preference and an application, or a mapping relationship between a path preference and an application identifier, or a mapping relationship between a path preference and all applications.

[0204] Receive the list of path preference mapping rules sent by the network-side device.

[0205] Optionally, the processor 810 is used for:

[0206] Based on the path preference mapping rule list and the priority information, obtain the path preference that matches the identifier of the target application.

[0207] Optionally, the path preference mapping rule list includes at least one path preference mapping rule sorted according to the priority information.

[0208] In this embodiment, the path preference mapping rule list sent by the network-side device to the first terminal is already sorted. This means that the network-side device sorted the path preference mapping rules according to a certain priority order when encoding the list. Once the terminal successfully matches a rule, it can stop matching other path preference mapping rules. This saves terminal computing resources, reduces computational complexity, and decreases user waiting time.

[0209] Optionally, each of the path preference mapping rules has a first indication field, which is used to indicate the priority information.

[0210] In this embodiment, new priority information is added to the encoding strategy of existing mapping rules to reflect the priority of each path preference mapping rule. Another advantage of doing so is that it can be backward compatible with more potential future path selection strategies.

[0211] Optionally, at least one application corresponds to one or more path preference mapping rules, or at least one application identifier corresponds to one or more path preference mapping rules.

[0212] Optionally, when at least one application corresponds to multiple path preference mapping rules, or when at least one application identifier corresponds to multiple path preference mapping rules, the priority of the path preference corresponding to the at least one application or application identifier in different path preference mapping rules is different.

[0213] Optionally, the processor 810 is used for:

[0214] The first indication information sent by the application layer or upper layer is obtained through the ProSe layer of the near-field service.

[0215] Optionally, the path preference includes at least one of the following: preference for PC5, preference for Uu, or no preference.

[0216] Optionally, the radio frequency unit 801 is further configured to:

[0217] When the target application's path preference is PC5, the first terminal uses the ProSe direct communication mechanism on PC5 to communicate with the second terminal.

[0218] When the path preference of the target application is Uu, the first terminal uses the Uu mechanism to communicate with the second terminal;
