[0129] S140, the accessible analysis identifier is sent to the terminal.

[0130] In one embodiment of the information acquisition method described in this invention, the terminal sends a first request message to a first network function to request access to an accessible analysis identifier. The first network function can obtain the analysis identifier subscribed to by the terminal and / or the analysis identifier supported by the network side according to the first request message, determine the analysis identifier accessible to the terminal, and return the accessible analysis identifier to the terminal, so that the terminal can obtain the accessible analysis identifier from the network function.

[0131] In this first embodiment, the first network function is one of the Access and Mobility Management Function (AMF) and the Session Management function (SMF).

[0132] In step S120, obtaining the analysis identifier of the terminal subscription based on the first request message includes:

[0137] Optionally, the first request message includes the analysis identifier and / or area of ​​interest (AOI) requested by the terminal. The third network function is the Network Repository Function (NRF).

[0138] It should be noted that the first request message includes the analysis identifier and / or area of ​​interest (AOI) requested by the terminal, or it can be interpreted as the first request message carrying or indicating the analysis identifier and / or area of ​​interest (AOI) requested by the terminal.

[0139] Using the information acquisition method described in Embodiment 1, the first network function determines the analysis identifiers that the terminal can access based on the analysis identifiers supported by the network side and / or the analysis identifiers that have been subscribed to; optionally, the first network function determines that an analysis identifier that is both supported by the network side and subscribed to is an accessible analysis identifier.

[0140] In this embodiment of the invention, optionally, in step S110, if the first request message received by the first network function includes the analysis identifier requested by the terminal, determining the accessible analysis identifier based on the analysis identifiers supported by the network side and / or the subscribed analysis identifiers includes:

[0141] The accessible analytics identifier is determined based on the analytics identifiers supported by the network side and the subscribed analytics identifiers, combined with the analytics identifier requested by the terminal.

[0142] In this first embodiment, the first network function determines that an analysis identifier that is simultaneously supported by the network side, subscribed to, and requested by the terminal is an accessible analysis identifier based on the analysis identifier supported by the network side, the analysis identifier that has been subscribed to, and the analysis identifier requested by the terminal.

[0143] Optionally, in one implementation, the first network function determines the analysis identifiers supported by the network side based on its local configuration; or sends a query request to the NRF to obtain the analysis identifiers supported by the network side. Specifically, the first network function obtains the supported analysis identifiers based on its local configuration or by sending a query request to the NRF; optionally, the query request sent by the first network function to the NRF also includes the analysis identifier requested by the terminal and / or the requested region of interest (AOI). Based on this query request, the NRF also provides the first network function with NWDAF or AF information for providing analysis results.

[0144] In this first embodiment, using the above implementation process, the first network function obtains an accessible analysis identifier and sends the determined accessible analysis identifier to the terminal.

[0147] S220, the first network function (AMF and / or SMF) sends a second request message to the second network function (UDM and / or AF). Optionally, the second request message includes the terminal's Subscription Permanent Identifier (SUPI). Based on the second request message, the second network function (UDM and / or AF) returns the Subscribed Analytics ID to the first network function (AMF and / or SMF).

[0148] S230, the first network function (AMF and / or SMF) obtains NWDAF information or AF information, and obtains the NWDAF SupportedAnalytics ID, which is the identifier of the supported analysis results obtained by NWDAF, based on local configuration or by sending a query request to NRF;

[0150] S250, the first network function (AMF and / or SMF) sends a message to the terminal carrying the accessible analytics identifier, Allowed Analytics ID.

[0151] Using this embodiment, the terminal can send a request message to the AMF or SMF to request access to the Analytics ID; in addition, the terminal can also obtain the accessible Analytics ID from the AMF or SMF to obtain the accessible Analytics ID from the network side, so as to further obtain the analysis results from the network side.

[0152] In addition, for AMF or SMF, it has the function of receiving the terminal's request to obtain the analysis identifier, and according to the received request message, it can obtain the subscribed analysis identifier from UDM or AF, and according to the local configuration or by sending a query request to NRF, it can obtain NWDAF or AF and the supported analysis identifier, determine the accessible analysis identifier, and send the accessible analysis identifier to the terminal.

[0158] Optionally, in the information acquisition method, the first network function is one of the Access and Mobility Management Function (AMF) and the Session Management Function (SMF).

[0159] The specific implementation process of the information acquisition method described in Embodiment 1 of this invention when applied to a terminal can be combined with... Figure 2 and Figure 3 Please refer to the above description; further details will not be provided here.

[0160] Example 2

[0161] Embodiment 2 of the present invention provides an information acquisition method, executed by a first network function, such as... Figure 4 As shown, the method includes:

[0162] S410, receive a first request message sent by the terminal, the first request message being used to request subscription to analysis results;

[0163] S420, based on the first request message, send a subscription request to the second network function to subscribe to the analysis results.

[0164] Using the information acquisition method described in Embodiment 2, the first network function can send a subscription request to the second network function based on the terminal's first request message, so as to subscribe to the analysis results for the terminal and enable the terminal to obtain the analysis results from the network side.

[0165] In this second embodiment, optionally, the first network function is one of the Access and Mobility Management Function (AMF), Session Management Function (SMF), and User Plane Function (UPF); the second network function is one of the Network Data Analysis Function (NWDAF) and Application Layer Function (AF).

[0166] Using this second embodiment, the terminal can subscribe to the analysis results from the NWDAF or AF through one of the AMF, SMF, and UPF, so as to obtain the analysis results from the network side.

[0167] Optionally, in step S410, the first network function receives a first request message sent by the terminal. Optionally, the first request message includes (carrying a carry or indicating) the analysis identifier and / or region of interest (AOI) requested by the terminal. Optionally, the AOI is the AOI of the requested analysis result.

[0168] Specifically, the first request message is used to request subscription to analysis results from the second network function. In this embodiment of the invention, when the first network function is UPF, UPF needs to parse the first request message sent by the terminal and identify it as a request message for subscribing to analysis results from NWDAF or AF.

[0169] Optionally, after receiving the first request message in step S410, the method further includes:

[0170] The second network function is obtained based on the local configuration to support providing the analysis results to the terminal; or the second network function is obtained by sending a query request to a third network function.

[0171] The third network function is Network Storage Function (NRF).

[0172] In this implementation, after receiving the first request message, the first network function determines, based on its local configuration, the NWDAF and / or AF that can provide analysis results before sending a subscription request to the second network function; or, it sends a query request to the NRF to query the NWDAF and / or AF that can provide analysis results.

[0173] Optionally, the query request and subscription request respectively include (carrying a carry or an indicator) the analysis identifier and / or area of ​​interest (AOI) requested by the terminal. In this implementation, after receiving the subscription request, the second network function sends the analysis results subscribed to by the terminal to the fourth network function.

[0174] Optionally, the fourth network function is one of AMF, SMF (Session Management Function), and UPF (User Plane Function).

[0175] In one embodiment of the present invention, optionally, the information acquisition method further includes, after the first network function sends a first request message sent by the receiving terminal and sends a subscription request to the second network function, the method further includes:

[0176] Obtain the analysis results sent by the second network function based on the subscription request;

[0177] The analysis results are sent to the terminal.

[0178] In one implementation method, the terminal sends a first request message to the first network function, and after the first network function sends a subscription request to the second network function, the second network function can return the analysis results subscribed to by the terminal to the terminal again. That is, the fourth network function is the same as the first network function.

[0179] In another implementation, optionally, the terminal sends a first request message to the first network function, and after the first network function sends a subscription request to the second network function, the second network function can return the analysis results to the terminal through the fourth network function, that is, the fourth network function is different from the first network function.

[0604] In this embodiment of the invention, the module can be implemented in software so that it can be executed by various types of processors. For example, an identified executable code module may include one or more physical or logical blocks of computer instructions, which may be constructed as objects, procedures, or functions. Nevertheless, the executable code of the identified module does not need to be physically located together, but may include different instructions stored in different bits, which, when logically combined, constitute the module and achieve the module's intended purpose.

[0605] In practice, an executable code module can be a single instruction or many instructions, and can even be distributed across multiple different code segments, different programs, and across multiple memory devices. Similarly, operational data can be identified within the module and can be implemented in any suitable form and organized within any suitable type of data structure. This operational data can be collected as a single dataset or distributed across different locations (including different storage devices), and can exist, at least in part, solely as electronic signals within the system or network.

Many different forms and embodiments are feasible without departing from the spirit and teachings of the invention. Therefore, the invention should not be construed as limiting the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided to make the invention complete and convey the scope of the invention to those skilled in the art.
