[0036] To further clarify the technical problems, technical approaches, and advantages that this disclosure aims to solve, they will be described in detail below with reference to the drawings and specific embodiments.

[0037] Furthermore, the phrase "one embodiment" or "one example" used throughout the description means that the specific features, structures, or characteristics related to the embodiment are included in at least one embodiment of this disclosure. Therefore, the phrases "in one embodiment" or "in one example" found throughout the specification do not necessarily refer to the same embodiment. Moreover, these specific features, structures, or characteristics can be incorporated into one or more embodiments in any suitable manner.

[0038] In the various embodiments of this disclosure, the magnitude of the sequence numbers of the following processes does not indicate the order in which they are executed. The execution order of each process should be determined by its function and inherent logic, and is not limited in any way to the implementation processes of the embodiments of this disclosure.

[0039] Furthermore, the terms "system" and "network" may be used interchangeably within this specification.

[0040] To address the problem in related technologies where a terminal cannot obtain analysis results from a network function, the embodiments of this disclosure provide an information acquisition method that solves the problem in related technologies where analysis results cannot be obtained from a network function by having the terminal send a request to the network function to obtain an accessible analysis identifier and / or a request to subscribe to analysis results, and by having the network function provide the analysis identifier and / or analysis results to the terminal.Specific embodiments of the information acquisition method according to specific embodiments of this disclosure will be described below. Example 1

[0041] Embodiment 1 of this disclosure provides an information acquisition method performed by a first network function. As shown in Figure 1, the method includes the following: In S110, a first request message is received from the terminal requesting the acquisition of an accessible analysis identifier. In S120, based on the first request message, the contracted analysis identifier of the terminal and / or the analysis identifier supported on the network side are obtained. In S130, the accessible analysis identifiers of the terminal are determined based on the contracted analysis identifiers of the terminal and / or the analysis identifiers supported on the network side. In S140, the accessible analysis identifier is transmitted to the terminal.

[0042] In one embodiment using the information acquisition method according to the embodiment of this disclosure, a terminal sends a first request message to a first network function to request the acquisition of an accessible analysis identifier. Based on the first request message, the first network function acquires the terminal's contracted analysis identifiers and / or analysis identifiers supported on the network side, then determines the analysis identifiers accessible to the terminal, and returns the accessible analysis identifiers to the terminal. Thus, the terminal can acquire accessible analysis identifiers from the network function.

[0043] In this embodiment 1, the first network function is one of the Access and Mobility Management Function (AMF) and Session Management Function (SMF).

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

[0045] Selectively, the second network function is one of the Application Layer Functions (AF) and Unified Data Management (UDM).

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

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

[0048] Furthermore, if the analysis identifier and / or region of interest (AOI) requested by the terminal is included in the first request message, it may be interpreted that the first request message carries or indicates the analysis identifier and / or region of interest (AOI) requested by the terminal.

[0049] According to the information acquisition method of Embodiment 1, the first network function determines the analysis identifiers accessible by the terminal based on the analysis identifiers supported by the network and / or the contracted analysis identifiers. Selectively, the first network function determines that analysis identifiers that are both supported by the network and contracted analysis identifiers are accessible.

[0050] In embodiments 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 a terminal, determining an accessible analysis identifier based on network-supported analysis identifiers and / or contracted analysis identifiers includes determining the accessible analysis identifier in relation to the analysis identifier requested by the terminal, based on network-supported analysis identifiers and contracted analysis identifiers.

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

[0052] Selectively, in one embodiment, the first network function determines network-supported analysis identifiers based on the local configuration, or obtains network-supported analysis identifiers by sending a query request to the NRF. Specifically, the first network function obtains supported analysis identifiers based on the local configuration or by sending a query request to the NRF. Selectively, the query request sent from the first network function to the NRF further includes the requested analysis identifier and / or requested area of ​​interest (AOI) from the terminal. Here, the NRF provides the first network function with NWDAF or AF information for providing analysis results based on the query request.

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

[0054] As shown in Figure 2, the information acquisition method according to Embodiment 1 of this disclosure includes the following specific process for a terminal to acquire an analytical identifier accessible from the network: In S210, the terminal sends a first request message to the first network function (AMF and / or SMF) that includes the requested analytics ID and / or the requested area of ​​interest (AOI). In S220, the first network function (AMF and / or SMF) sends a second request message to the second network function (UDM and / or AF). Selectively, the second request message includes the terminal's Subscription Permanent Identifier (SUPI). The second network function (UDM and / or AF) feeds back the Subscribed Analytics ID to the first network function (AMF and / or SMF) based on the second request message. In S230, the first network function (AMF and / or SMF) obtains NWDAF information or AF information based on the local configuration or by sending a query request to the NRF, and obtains a supported analytics identifier (NWDAF Supported Analytics ID) from the NWDAF. In S240, the first network function (AMF and / or SMF) determines the Allowed Analytics ID based on the analytics identifiers supported on the network side and the contracted analytics identifiers, in relation to the analytics identifiers requested by the terminal. In S250, the first network function (AMF and / or SMF) sends a message to the terminal that carries the Allowed Analytics ID.

[0055] According to Embodiment 1, the terminal can send a request message to the AMF or SMF to request the acquisition of an accessible analytics ID. Furthermore, by obtaining the accessible analytics ID from the AMF or SMF, the terminal can acquire an analytics ID accessible from the network side, and further acquire analysis results from the network side.

[0056] Furthermore, AMF or SMF is equipped with a function to receive request messages from the terminal to request the acquisition of analysis identifiers, and based on the received request messages, can acquire contracted analysis identifiers from UDM or AF, acquire NWDAF or AF and supported analysis identifiers based on the local configuration, or acquire them by sending a query request to NRF, determine the accessible analysis identifiers, and send those accessible analysis identifiers to the terminal.

[0057] One embodiment of Example 1 of this disclosure further provides an information acquisition method performed by a terminal. As shown in Figure 3, the method includes the following: In S310, a first request message is sent to the first network function to request the acquisition of an accessible analysis identifier. In S320, an accessible analysis identifier transmitted from the first network function is received.

[0058] In one embodiment of the information acquisition method according to Embodiment 1, when applied to a first network function, the terminal can send a request message to the first network function to request the acquisition of an analysis identifier. Based on the received request message, the first network function can acquire a contracted analysis identifier from the UDM or AF, acquire the NWDAF or AF and supported analysis identifiers based on the local configuration, or acquire them by sending a query request to the NRF, determine the accessible analysis identifiers, and send the accessible analysis identifiers to the terminal. Thus, the terminal can acquire the accessible analysis identifiers from the network side, and further acquire the analysis results from the network side.

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

[0060] Selectively, 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.

[0061] The specific implementation process when the information acquisition method according to Embodiment 1 of this disclosure is applied to a terminal can be described above in relation to Figures 2 and 3, and will not be described in further detail here. Example 2

[0062] Embodiment 2 of this disclosure provides an information acquisition method performed by a first network function. As shown in Figure 4, the method includes the following: In S410, a first request message is received from the terminal requesting subscription to the analysis results. In S420, based on the first request message, a subscription request to subscribe to the analysis results is sent to the second network function.

[0063] According to the information acquisition method of the second embodiment, the first network function can subscribe to analysis results for the terminal by sending a subscription request to the second network function based on the terminal's first request message, thereby enabling the terminal to acquire the analysis results from the network side.

[0064] In the second embodiment, the first network function is selectively one of the access and mobility management function (AMF), the session management function (SMF), and the user plane function (UPF), and the second network function is one of the network data analysis function (NWDAF) and the application layer function (AF).

[0065] According to this embodiment 2, the terminal can subscribe to analysis results from NWDAF or AF via one of AMF, SMF, and UPF, and obtain the analysis results from the network side.

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

[0067] Specifically, the first request message is used to request that the analysis results be subscribed to by a second network function. In embodiments of this disclosure, if the first network function is a UPF, the UPF needs to analyze the first request message sent from the terminal and identify that the first request message is a request message to subscribe to the analysis results from an NWDAF or AF.

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

[0069] Here, the third network function is the network memory function (NRF).

[0070] According to this embodiment, after receiving a first request message and before sending a subscription request to a second network function, the first network function determines, based on its local configuration, which NWDAFs and / or AFs can provide analysis results, or sends a query request to the NRF to query which NWDAFs and / or AFs can provide analysis results.

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

[0072] Selectively, the fourth network function is one of the following: AMF, session management function SMF, and user-facing function UPF.

[0073] In one embodiment of the embodiments of the present disclosure, selectively, according to the information acquisition method, after a first network function receives a first request message transmitted from a terminal and transmits a subscription request to a second network function, the method further includes acquiring analysis results transmitted from the second network function based on the subscription request and transmitting the analysis results to the terminal.

[0074] According to this embodiment, in one embodiment, a terminal sends a first request message to a first network function, the first network function sends a subscription request to a second network function, and then the second network function sends the analysis results subscribed to by the terminal back to the terminal. That is, the fourth network function is the same as the first network function.

[0075] In another embodiment, the terminal may selectively send a first request message to the first network function, and the first network function may send a subscription request to the second network function, after which the second network function may return the analysis results to the terminal via the fourth network function. That is, the fourth network function is different from the first network function.

[0076] In one embodiment, selectively, for simple models and / or infrequently queryable analysis results, the second network function transmits the analysis results to the terminal via AMF and / or SMF, while for complex models and / or frequently queryable analysis results, the second network function transmits the analysis results to the terminal via UPF, and further, when the first network function sends a subscription request to NWDAF or AF, the subscription request also includes the terminal's address information so that the analysis results can be transmitted to the terminal via the corresponding UPF.

[0077] According to Embodiment 2, the terminal can send a request message to the AMF, SMF, and / or UPF to request subscription to the analysis results, and furthermore, the subscribed analysis results can be obtained from the NWDAF or AF via the AMF, SMF, and / or UPF, thereby solving the problem in related technologies where analysis results cannot be obtained from the network side.

[0078] Furthermore, for AMF, SMF, and UPF, the system includes a function to receive a request message from the terminal to request subscription of analysis results, and to send a subscription request to NWDAF or AF based on the request message to subscribe to the analysis results, and for NWDAF and AF, it includes a function to send the analysis results to at least one of AMF, SMF, and UPF.

[0079] One embodiment of Example 2 of this disclosure further provides an information acquisition method performed by a second network function. As shown in Figure 5, the method includes the following: In S510, a subscription request is received from the first network function to request subscription to the analysis results. In S520, the subscribed analysis results are transmitted to the fourth network function based on the subscription request.

[0080] In one embodiment of the 2nd embodiment, 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 results to the terminal via the fourth network function, thereby enabling the terminal to acquire the analysis results from the network side.

[0081] Selectively, the first network function is one of the access and mobility management function AMF, the session management function SMF, and the user-facing function UPF; the second network function is one of the NWDAF and the application layer function AF; and the fourth network function is one of the AMF, the session management function SMF, and the user-facing function UPF.

[0082] Selectively, the subscription request includes the analysis identifier and / or area of ​​interest (AOI) of the requested analysis results.

[0083] Selectively, the subscription request may also include the address information of the terminal.

[0084] One embodiment of Example 2 of this disclosure further provides a method for acquiring information performed by a terminal. As shown in Figure 6, the method includes the following: In S610, a first request message is sent to the first network function to request subscription to the analysis results. In S620, the subscribed analysis results are received from the fourth network function.

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

[0086] Selectively, the first network function is one of the access and mobility management function AMF, the session management function SMF, and the user-facing function UPF, and the fourth network function is one of the AMF, the session management function SMF, and the user-facing function UPF.
