Description

Technical Field

[0001] This application relates to the field of communication technology, specifically to a strategy formulation method, apparatus, device, and readable storage medium. Background Technology

[0002] Application function (AF) guidance provides information to the Policy Control Function (PCF), including application traffic descriptors and route selection parameters. The PCF then generates a User Route Selection Policy (URSP) and its priority based on this information. In this process, the AF provides information to the PCF, which directly generates URSP rules without performing any conditional filtering or judgment. In reality, the AF lacks knowledge of the operator's network conditions, and the route it provides is likely not the optimal path. The PCF cannot select the best route for the user simply by using all the information from the AF. Summary of the Invention

[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] The term "comprising," and any variations thereof, used in the specification and claims of this application, is intended to cover a non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus. Furthermore, the use of "and / or" in the specification and claims indicates at least one of the connected objects, such as A and / or B, indicating the inclusion of A alone, B alone, or both A and B.

[0052] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0053] It is worth noting that the technologies described in this application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" in this application are often used interchangeably, and the described technologies can be used with the systems and radio technologies mentioned above, as well as with other systems and radio technologies. However, the following description describes New Radio (NR) systems for illustrative purposes, and the term NR is used in most of the following description, although these technologies can also be applied to applications other than NR systems, such as 6th Generation (6G) communication systems.

[0054] See Figure 1 This application provides a strategy formulation method, which includes steps 101 and 102.

[0055] Step 101: The first network function obtains the first information provided by the first function;

[0056] In one embodiment of this application, the first information includes one or more of the following:

[0057] (1) Service descriptor (application traffic descriptor);

[0058] (2) Application traffic descriptor;

[0059] (3) Route selection parameter;

[0060] (4) Priority information.

[0061] Optionally, the first network function includes one or more of the following: PCF, Unified Data Management (UDM), and Session Management Function (SMF), and the first function includes one or more of the following: Application function (AF) and Edge Application Platform (MEP platform).

[0062] Step 102: Based on the first information, the first network function determines the user routing policy URSP rules and / or the priority of the URSP rules.

[0063] In other words, the first network function does not directly use the first information to generate URSP rules and / or the priority of the URSP rules, but rather determines whether to generate URSP rules and / or the priority of the URSP rules based on the first information. Specifically, this can include two cases:

[0064] 1. The first network function may use the first information to generate URSP rules and / or the priority of the URSP rules;

[0065] Here, it only means that the first network function "may" use the first information to generate the data; there's a possibility that it might be used, or there's a possibility that it might not. One possible way to determine whether to use the first information is to check if it meets preset conditions. If it does, then the first information is used for generation. These preset conditions will be described in detail later.

[0066] 2. If the first information does not meet certain preset conditions, then the first information will not be used, and the URSP rules and / or the priority of the URSP rules will not be generated.

[0067] In other words, the “decision” in step 102 includes: deciding on the priority of generating URSP rules and / or the URSP rules, and deciding on the priority of not generating URSP rules and / or the URSP rules.

[0068] In this embodiment of the invention, after the PCF receives the first information, compared to the prior art where the first information is directly used to generate URSP rules, this embodiment considers whether the first information meets preset conditions. That is, it performs a judgment on the first information. If the conditions are not met, the first information is not used, and no URSP rules and / or priorities are generated. If the conditions are met, URSP rules and / or priorities are generated at least based on the first information. The first network function can combine the UE's situation and the first function's situation to comprehensively consider and set URSP rules and / or priorities. This allows for providing the UE with more suitable URSP rules and / or priorities.

[0069] In one embodiment of this application, after step 102, the method may further include: a first network function sending the URSP rule and / or the priority of the URSP rule to the user.

[0070] Optionally, the URSP rules generated by the first network function cannot be set as URSP rules with full matching service descriptors.

[0071] In this embodiment of the application, the first network function considers the information provided by the first function, makes a judgment and generates URSP rules and the priority of URSP rules, and selects the best routing path for the user.

[0072] See Figure 2 This application provides a strategy formulation method, which includes steps 201, 202 and 203.

[0073] Step 201: The first network function obtains the first information provided by the first function;

[0074] Step 202: The first network function obtains second information and / or third information, wherein the second information includes at least: user subscription data; and the third information includes at least: operator local policies;

[0075] The operator's local policy may include one or more of the following: the deployment location of the third network function and the quality of network routing, such as the congestion level of the routing path and the traffic load of the routing path. The user subscription data may include one or more of the following: Data Network Name (DNN) and Single Network Slice Selection Assistance Information (S-NSSAI). When the user subscription data is DNN and / or S-NSSAI, the first information can be DNN and / or S-NSSAI in the Route Selection parameter, so that the PCF can determine the consistency between the DNN and / or S-NSSAI in the received first information and the DNN and / or S-NSSAI in the user subscription data. The consistency determination here is one of the preset conditions mentioned above. That is, if they are consistent, the first information is used to generate USRP rules and / or USRP rule priorities; if they are inconsistent, the first information is not favorable, and USRP rules and / or USRP rule priorities are not generated. Of course, the preset conditions can also be other cases, such as determining the consistency of other parameters or determining that other parameters meet specified conditions.

[0076] The acquisition of second and / or third information here can be understood as the first network function obtaining second and / or third information from other network elements, or it can be understood as storing second and / or third information itself and retrieving it when needed.

[0077] The aforementioned third network function includes one or more of the following: User Plane Function (UPF), or the user plane (PGW-U) of the PDN gateway, the control plane (PGW-C) of the PDN gateway, and the industry gateway.

[0078] Step 203: The first network function determines the priority of the URSP rules and / or the URSP rules based on the first information, the second information and / or the third information.

[0079] Based on the first information, the second information, and / or the third information, there are at least three possibilities:

[0080] 1. First information and second information;

[0081] 2. First information and third information;

[0082] 3. First information, second information, and third information.

[0083] In one embodiment of this application, after step 203, the method may further include: a first network function sending the URSP rule and / or the priority of the URSP rule to the user.

[0084] Optionally, the URSP rules generated by the first network function cannot be set as URSP rules with full matching service descriptors.

[0085] In this embodiment, the first network function comprehensively considers the information provided by the first function, as well as the routing and usage of subscription data and / or the operator network, to make a judgment and generate URSP rules and their priorities. This takes into account the user's subscription data and / or the operator network and application conditions, selecting the best routing path for the user.

[0086] See Figure 3 This application provides a strategy formulation method, which includes the following steps: step 301, step 302, step 303, and step 304.

[0087] Step 301: The first network function obtains the first information provided by the first function;

[0088] Step 302: The first network function obtains second information and / or third information, wherein the second information includes at least: user subscription data; and the third information includes at least: operator local policies;

[0089] The operator's local strategy may include one or more of the following: the deployment location of third-party network functions and the quality of network routing, such as the degree of congestion of routing paths and the traffic load of routing paths. The user subscription data may include one or more of the following: DNN, S-NSSAI.

[0090] Step 303: The first network function determines the URSP rule and / or the priority of the URSP rule based on the first information, the second information and / or the third information.

[0091] In one embodiment of this application, after step 303, the method may further include: a first network function sending the URSP rule and / or the priority of the URSP rule to the user.

[0092] Optionally, the URSP rules generated by the first network function cannot be set as URSP rules with full matching service descriptors.

[0093] Step 304: The first network function sends the fourth information to the first function;

[0094] The fourth information indicates whether the first information is used by the first network function to determine the URSP rule and / or the priority of the URSP rule.

[0095] This is one scenario for the fourth information. The fourth information can also indicate whether the URSP rule and / or the priority of the URSP rule were generated, or whether the URSP rule and / or the priority of the URSP rule were successfully generated or failed to be generated.

[0096] Furthermore, the fourth message can indicate only the successful generation or only the failed generation. It's understandable that in such cases, if a situation other than the fourth message indicates occurs, the first network function will not provide feedback to the first function. Alternatively, situations not indicated by the fourth message can be reported to the first function via other messages.

[0097] In one embodiment of this application, the step of the first network function sending fourth information to the first function includes:

[0098] The first network function feeds back the fourth information to the first function based on whether the first information is consistent with the DNN and / or S-NSSAI in the second information.

[0099] Furthermore, the first network function feeds back the fourth information to the first function through the second network function.

[0100] For example, the second network function could be a Network Exposure Function (NEF), but it is not limited to this.

[0101] In this embodiment, the first network function comprehensively considers the information provided by the first function, user subscription data, and / or the routing and usage of the operator's network to make a judgment and generate URSP rules and their priorities. This takes into account both the operator's network conditions and application conditions, selecting the best routing path for the user.

[0102] The embodiments of this application are described below, taking PCF as the first network function, AF as the first function, and NEF as the second network function as an example, in conjunction with Embodiment 1 and Embodiment 2.

[0103] Example 1: AF guidance PCF decision URSP rules process.

[0104] See Figure 4 The specific steps include:

[0105] Step 0: The UE registers with the network;

[0106] Step 1: Create an AF request;

[0107] For example, the Application Provider (AF) calls the Service Parameter Create (Nnef_ServiceParameter_Create) operation to provide the application's business routes and their priorities. The AF carries a service descriptor, an application traffic descriptor, route selection parameters, and priorities.

[0108] Alternatively, the Application Filter (AF) can invoke the Service Parameter Update (Nnef_ServiceParameter_Update) operation to update the application's service routes and their priorities. The AF carries the service descriptor, application traffic descriptor, route selection parameter, and precedence.

[0109] Step 2: The AF sends a capability open service creation request to the NEF, and the NEF authorizes and approves the capability open service creation request. The NEF maps and transforms the information in the capability open service creation request, and a transaction reference ID also needs to be assigned during the service creation parameter process.

[0110] Step 3: NEF associates the received information with the Transaction Reference ID and stores it in the Unified Data Repository (UDR).

[0111] Step 4: The PCF receives the updated AF information from the UDR notification (including the application traffic descriptor, route selection parameter, and precedence).

[0112] Step 5: Based on the information provided by the AF, as well as user subscription data and / or operator local policies, the PCF comprehensively adds and updates user routing selection policies, and sends them to the AF and / or UE.

[0113] Step 6: PCF reports the usage of the information provided by AF guidance to NEF, which then forwards it to AF. If it is a new request, NEF sends the Transaction Reference ID to AF along with it.

[0114] Example 2: PCF updates URSP rules based on information provided by AF.

[0115] Step 1: AF guidance provides service descriptor, application traffic descriptor, route selection parameter and precedence information to PCF.

[0116] Step 2: PCF examines the DNN and / or S-NSSAI in the user's subscription data.

[0117] Step 3: If the information provided by the AF is consistent with the DNN and / or S-NSSAI in the user's contract data, the PCF indicates the content of the information provided by the AF that has been used in determining the URSP rules and / or the priority of the URSP rules.

[0118] Step 4: If the information provided by AF is inconsistent with the DNN and / or S-NSSAI in the user's contract data, the PCF instructs to cancel the creation of a new URSP rule or the update of a URSP rule, or instructs to include content from the information provided by AF that was not used in determining the URSP rule and / or the priority of the URSP rule.
