Thus, the appearances of "in one embodiment" or "in one embodiment" in various places throughout the specification do not necessarily refer to the same embodiment. Moreover, the particular feature, structure, or characteristic may be incorporated in any suitable manner in one or more embodiments.

[0038] In addition, in various embodiments of the present disclosure, the magnitude of the sequence number of each process does not mean the order of execution. The execution order of each process should be determined by its function and inherent logic, and is not limited to the implementation process of the embodiments of the present disclosure.

[0039] Additionally, as used herein, the terms "system" and "network" may be used interchangeably.

[0040] In order to solve the problem in the related art that a terminal cannot obtain analysis results from a network function, an embodiment of the present disclosure provides an information acquisition method that solves the problem in the related art that a terminal cannot obtain analysis results from a network function by transmitting a request for requesting acquisition of an accessible analysis identifier and / or a request for requesting subscription to analysis results, etc. from a terminal to a network function, and providing the analysis identifier and / or the analysis result from the network function to the terminal. Hereinafter, a specific embodiment of the information acquisition method according to a specific embodiment of the present disclosure will be described. Example 1

[0041] A first embodiment of the present disclosure provides an information acquisition method performed by a first network function. As shown in FIG. 1, the method includes: At S110, a first request message sent from a terminal to request obtaining an accessible analysis identifier is received. In S120, a subscribed analysis identifier of the terminal and / or a network-side supported analysis identifier is obtained according to the first request message. In S130, an accessible analysis identifier of the terminal is determined based on a subscribed analysis identifier of the terminal and / or an analysis identifier supported by a network side. At S140, the accessible analysis identifier is sent to the terminal.

[0042] In one embodiment using the information acquisition method according to the embodiment of the present disclosure, the terminal sends a first request message to a first network function to request acquisition of an accessible analysis identifier, and the first network function determines an accessible analysis identifier of the terminal after acquiring a subscribed analysis identifier of the terminal and / or a network-side supported analysis identifier based on the first request message, and returns the accessible analysis identifier to the terminal. Thus, the terminal can acquire the accessible analysis identifier from the network function.

[0043] In the first embodiment, the first network function is one of an Access and Mobility Management Function (AMF) and a Session Management Function (SMF).

[0044] Here, in step S120, obtaining a subscribed analysis identifier of the terminal based on the first request message includes obtaining a subscribed analysis identifier sent from the second network function based on the second request message by sending a second request message to a second network function based on the first request message.

[0045] Optionally, the second network function is one of an Application Function (AF) and a Unified Data Management (UDM).

[0046] Optionally, in step S120, obtaining an analysis identifier supported on the network side based on the first request message includes obtaining an analysis identifier supported on the network side based on the first request message using a local configuration, or includes obtaining an analysis identifier supported on the network side by sending a query request to a third network function.

[0047] Optionally, the first request message includes an analysis identifier and / or an Area of ​​Interest (AOI) requested by the terminal, where the third network function is a Network Repository Function (NRF).

[0048] In addition, the inclusion of the analysis identifier and / or area of ​​interest AOI requested from the terminal in the first request message may be interpreted as the first request message carrying or indicating the analysis identifier and / or area of ​​interest AOI requested from the terminal.

[0049] According to the information acquisition method of the first embodiment, the first network function determines an accessible analysis identifier of the terminal based on the analysis identifier supported by the network side and / or the subscribed analysis identifier. Optionally, the first network function determines that an analysis identifier that corresponds to both the analysis identifier supported by the network side and the subscribed analysis identifier corresponds to the accessible analysis identifier.

[0050] In an embodiment of the present disclosure, optionally, if the first request message received by the first network function in step S110 includes an analysis identifier requested by the terminal, determining an accessible analysis identifier based on the analysis identifiers supported by the network side and / or the subscribed analysis identifiers includes determining the accessible analysis identifier based on the analysis identifiers supported by the network side and the subscribed analysis identifiers, also in relation to the analysis identifier requested by the terminal.

[0051] In this embodiment 1, based on the analysis identifier supported on the network side, the contracted analysis identifier, and the analysis identifier requested from the terminal, the first network function determines that an analysis identifier that simultaneously corresponds to the analysis identifier supported on the network side, the contracted analysis identifier, and the analysis identifier requested from the terminal corresponds to an accessible analysis identifier.

[0052] Optionally, in one embodiment, the first network function determines the analysis identifiers supported on the network side based on a local configuration or sends a query request to the NRF to obtain the analysis identifiers supported on the network side. Specifically, the first network function obtains the supported analysis identifiers based on a local configuration or sends a query request to the NRF to obtain them. Optionally, the query request sent from the first network function to the NRF further includes the analysis identifiers requested by the terminal and / or the requested area of ​​interest AOI. Here, the NRF provides the first network function with information of the NWDAF or AF for providing the analysis result based on the query request.

[0053] In this embodiment 1, according to the above implementation process, the first network function obtains an accessible analysis identifier, and sends the determined accessible analysis identifier to the terminal.

[0054] In the information acquisition method according to the first embodiment of the present disclosure, as shown in FIG. 2 , a specific process of a terminal acquiring an analysis identifier accessible from a network includes the following: At S210, the terminal sends a first request message including a Requested Analytics ID and / or a requested area of ​​interest AOI requested from the terminal to a first network function (AMF and / or SMF). In 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 a User Permanent Identifier (SUbscription Permanent Identifier: SUPI) of the terminal. The second network function (UDM and / or AF) feeds back a Subscribed Analytics ID to the first network function (AMF and / or SMF) based on the second request message. At S230, the first network function (AMF and / or SMF) obtains NWDAF information or AF information based on a local configuration or by sending a query request to the NRF, and obtains a supported analytics result identifier (NWDAF Supported Analytics ID) from the NWDAF. At S240, the first network function (AMF and / or SMF) determines an accessible analytics identifier (Allowed Analytics ID) based on the analytics identifiers supported on the network side and the contracted analytics identifier, also related to the analytics identifier requested by the terminal. At S250, the first network function (AMF and / or SMF) sends a message carrying the accessible analytics identifier (Allowed Analytics ID) to the terminal.

[0055] According to the first embodiment, the terminal can transmit a request message to the AMF or SMF to request acquisition of an accessible analysis identifier (Analytics ID). Furthermore, the terminal can acquire the accessible analysis identifier from the AMF or SMF, thereby acquiring an accessible analysis identifier from the network side, and further acquiring an analysis result from the network side.

[0056] In addition, the AMF or SMF has a function of receiving a request message from the terminal to request the acquisition of an analysis identifier, and based on the received request message, can acquire a contracted analysis identifier from the UDM or AF, acquire the NWDAF or AF and a supported analysis identifier based on a local configuration or by sending a query request to the NRF, determine an accessible analysis identifier, and send the accessible analysis identifier to the terminal.

[0057] In one embodiment of the present disclosure, an information acquisition method executed by a terminal is further provided. As shown in FIG. 3, the method includes: At S310, a first request message is sent to a first network function to request obtaining an accessible analysis identifier. At S320, an accessible analysis identifier transmitted from the first network function is received.

[0058] In one embodiment of the information acquisition method according to the first embodiment, when applied to a first network function, the terminal can send a request message to the first network function to request acquisition of an analysis identifier, and the first network function can acquire a contracted analysis identifier from the UDM or AF based on the received request message, acquire the NWDAF or AF and a supported analysis identifier based on a local configuration, or send a query request to the NRF to acquire, determine an accessible analysis identifier, and send the accessible analysis identifier to the terminal. Thus, the terminal can acquire the accessible analysis identifier from the network side, and can further acquire the analysis result from the network side.

[0059] Optionally, in the information acquisition method, the first request message includes an analysis identifier and / or an area of ​​interest AOI requested by the terminal.

[0060] Optionally, in the information acquisition method, the first network function is one of an Access and Mobility Management Function AMF and a Session Management Function SMF.

[0061] When the information acquisition method according to the first embodiment of the present disclosure is applied to a terminal, the specific implementation process may refer to the above description in relation to FIG. 2 and FIG. 3, and will not be described in further detail here. Example 2

[0062] The second embodiment of the present disclosure provides an information obtaining method performed by a first network function. As shown in FIG. 4, the method includes: At S410, a first request message sent from a terminal to request a subscription to an analysis result is received. At S420, a subscription request for subscribing to an analysis result is sent to a second network function based on the first request message.

[0063] According to the information acquisition method of Example 2, the first network function can subscribe to the analysis result for the terminal by sending a subscription request to the second network function based on the first request message of the terminal, so that the terminal can acquire the analysis result from the network side.

[0064] In this embodiment 2, optionally, the first network function is one of an access and mobility management function AMF, a session management function SMF, and a user plane function (User Plane Function: UPF), and the second network function is one of a network data analysis function NWDAF and an application layer function AF.

[0065] According to the second embodiment, the terminal can subscribe to the analysis result from the NWDAF or AF via one of the AMF, SMF, and UPF, and obtain the analysis result from the network side.

[0066] Optionally, in step S410, the first network function receives a first request message sent from the terminal. Optionally, the first request message includes (carries or indicates) an analysis identifier and / or an area of ​​interest AOI requested from the terminal. Optionally, the area of ​​interest AOI is an AOI of a requested analysis result.

[0067] Specifically, the first request message is used to request a second network function to subscribe to the analysis result. In an embodiment of the present disclosure, if the first network function is a UPF, the UPF needs to analyze the first request message sent by the terminal and identify that the first request message is a request message for subscribing to the analysis result from the NWDAF or the AF.

[0068] Optionally, after receiving the first request message in step S410, the method further includes obtaining the second network capability that supports providing the analysis result to the terminal based on a local configuration, or obtaining the second network capability by sending a query request to a third network capability.

[0069] Here, the third network function is a network storage function NRF.

[0070] According to the embodiment, after receiving the first request message and before sending a subscription request to the second network function, the first network function determines an NWDAF and / or AF that can provide the analysis result based on a local configuration, or sends a query request to the NRF to query an NWDAF and / or AF that can provide the analysis result.

[0071] Optionally, the query request and the subscription request respectively include (carry or indicate) the analysis identifier and / or the area of ​​interest AOI requested from the terminal. According to this embodiment, after receiving the subscription request, the second network function transmits the analysis result subscribed to by the terminal to the fourth network function.

[0072] Optionally, the fourth network function is one of an AMF, a session management function SMF, and a user plane function UPF.

[0073] Optionally, in one embodiment of the embodiment of the present disclosure, according to the information acquisition method, after a first network function receives a first request message sent from a terminal and sends a subscription request to a second network function, the method further includes: acquiring an analysis result sent from the second network function based on the subscription request, and sending the analysis result to the terminal.

[0074] According to this embodiment, in one embodiment, after the terminal sends a first request message to the first network function and the first network function sends a subscription request to the second network function, the second network function may return the analysis result subscribed to by the terminal to the terminal again, that is, the fourth network function is the same as the first network function.

[0075] In another embodiment, optionally, after sending the first request message from the terminal to the first network function and sending the subscription request from the first network function to the second network function, the second network function may return the analysis result to the terminal via a fourth network function, i.e. the fourth network function is different from the first network function.

[0076] In one embodiment, selectively, for simple models and / or analysis results with low query frequency, the second network function transmits the analysis results to the terminal via the AMF and / or SMF, while for complex models and / or analysis results with high query frequency, the second network function transmits the analysis results to the terminal via the UPF, and further, when sending a subscription request from the first network function to the NWDAF or AF, the subscription request also includes the address information of the terminal so that the analysis results can be sent to the terminal via the corresponding UPF.

[0077] According to the second embodiment, the terminal can send a request message to the AMF, SMF and / or UPF to request subscription to the analysis result, and can further obtain the subscribed analysis result from the NWDAF or AF via the AMF, SMF and / or UPF, thereby resolving the problem in the related art that the analysis result cannot be obtained from the network side.

[0078] It also has a function for receiving a request message from a terminal to request a subscription to the analysis result for the AMF, SMF, and UPF, and for transmitting a subscription request to the NWDAF or AF to subscribe to the analysis result based on the request message, and for the NWDAF and AF, a function for transmitting the analysis result to at least one of the AMF, SMF, and UPF.

[0079] In one embodiment of the present disclosure, an information obtaining method is further provided, which is performed by a second network function. As shown in FIG. 5, the method includes: At S510, a subscription request sent from a first network function to request a subscription to an analysis result is received. At S520, the subscribed analysis result is sent to a fourth network function based on the subscription request.

[0080] In one embodiment of Example 2, according to the information acquisition method, the first network function can send a subscription request to the second network function based on the first request message of the terminal, and the second network function can provide the analysis result to the terminal via the fourth network function, so that the terminal can obtain the analysis result from the network side.

[0081] Alternatively, the first network function is one of an access and mobility management function AMF, a session management function SMF and a user plane function UPF, the second network function is one of an NWDAF and an application layer function AF, and the fourth network function is one of an AMF, a session management function SMF and a user plane function UPF.

[0082] Optionally, the subscription request includes an analysis identifier and / or an area of ​​interest AOI for the requested analysis results.

[0083] Optionally, the subscription request also includes address information of the terminal.

[0084] In one embodiment of the present disclosure, an information acquisition method executed by a terminal is further provided. As shown in FIG. 6 , the method includes: At S610, a first request message is sent to a first network function to request a subscription to the analysis result. At S620, the subscribed analysis results are received from a fourth network function.

[0085] Optionally, in the information acquisition method, the first request message includes an analysis identifier of a requested analysis result and / or an area of ​​interest AOI.
