Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to an information processing method, apparatus, network function, and storage medium. Background Technology

[0002] The Sensing Function (SF) is an independent logical function in the 5G Core Network (5GC), specifically responsible for sensing data collection, sensing data analysis, and sensing information output, providing sensing services to third-party systems. As a standardized network element introduced by 3GPP in 5GC, the SF is the engine of 5GC's sensing services, featuring standardized capabilities, aggregation of network sensing data, and higher real-time performance.

[0003] As a core network awareness service processing node, the SF (Service Provider) may need to be reselected due to changes in user mobility. For example, when a terminal (UE, User Equipment) moves, the current SF may be unable to continue providing intelligent location analysis. Considering this scenario, the SF node needs to have the ability to reselect a target SF and continue providing awareness services. Summary of the Invention

[0064] Figure 1 A schematic diagram defining the network architecture for the 5G Core Network (5GC) standard. Figure 1 As shown, 5G networks include various network elements, and the control plane adopts a service-based interface (SBI). 5G networks urgently need a comprehensive review of how to support sensing services from multiple aspects, including architecture, key issues, and data collection mechanisms and the output of sensing data analysis results.

[0065] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0066] This invention provides an information processing method applied to sensing functions. Figure 2 This is a flowchart illustrating the information processing method according to an embodiment of the present invention. Figure 1 ,like Figure 2 As shown, the method includes:

[0067] Step 101: The first sensing function receives first information sent by the Access and Mobility Management Function (AMF), the first information including at least the area identification information of the terminal (UE, User Equipment);

[0068] Step 102: If the first sensing function determines that it cannot provide sensing services to the terminal based on the first information, it obtains a second sensing function that can provide sensing services to the terminal from the first network function and initiates a switch to the second sensing function.

[0069] In this embodiment, the first sensing function is the sensing function that currently provides sensing services to the terminal. Specifically, the sensing service may include sensing data acquisition, sensing data analysis, and output of sensing data analysis results (sensing information).

[0070] The first sensing function receives first information sent by the AMF, which is location-related information provided by the AMF and includes at least the terminal's area identification information. Optionally, the area identification information includes at least one of the following: Tracking Area Identity (TAI) and Cell ID.

[0071] It should be noted that the AMF in this embodiment is the AMF of the current serving terminal. It can be the same AMF in the communication network or a different AMF. That is, the first sensing function obtains the first information from the AMF of the terminal after the service location has changed. The AMF after the service location has changed can be the AMF before the service location has changed or it can be a different AMF than the AMF before the service location has changed.

[0072] The first network function can be Figure 1 The Network Repository Function (NRF) is involved. In step 102, the first sensing function determines whether it can continue to provide sensing services to the terminal based on the first information. If it cannot provide sensing services to the terminal, it initiates a sensing function reselection process, that is, it queries the first network function for a second sensing function that can provide sensing services to the terminal and initiates a switch to the second network function.

[0073] This embodiment obtains the user's location change event and the user's area identification information through AMF. After the user's location changes, it queries the second sensing function that provides sensing services to the terminal after the location change based on the first network function, and initiates a switch to the second sensing function. This can realize the reselection of sensing functions based on user mobility and achieve efficient reselection of sensing network elements on the basis of inheriting the existing network architecture.

[0074] In one embodiment, the method may further include: step 100, the first sensing function sends a first message to a first AMF, the first message being used to request subscription to a terminal location change event. In this embodiment, the first sensing function subscribes to the terminal's location change event from the first AMF, the first AMF being the AMF that served the terminal before the terminal's location changed.

[0075] AMF can obtain user location change events. The location change events can specifically be events and / or statistical information related to terminal mobility management that AMF can provide. For example, the location information of the terminal provided by AMF to the first sensing function based on the event open service specifically includes the identification information of the area where the terminal is located.

[0076] In this embodiment of the invention, the first sensing function subscribes to the AMF (single or group of) location change events of terminals. After the terminal location changes, the sensing function supports querying the NRF to obtain the target sensing network element (i.e., the second sensing function) that provides sensing services to the terminal at the new location, thereby realizing the reselection of sensing network elements.

[0077] As an optional implementation, the first sensing function receiving the first information sent by the AMF may include: the first sensing function receiving the first information sent by the first AMF, the first information including at least the area identification information after the terminal location change; the first AMF is the AMF serving the terminal before and after the terminal location change.

[0078] In this embodiment, the AMF serving the terminal remains the same before and after the terminal's location changes, namely the first AMF. It can be understood that before the terminal's location changes, the first sensing function subscribes to the terminal's location change event from the first AMF serving the terminal before the location change, and the first AMF is able to sense the terminal's location change event. After the terminal's location changes, the first AMF notifies the first sensing function of the terminal's location change event; that is, the first sensing function receives first information sent from the first AMF, the first information including at least the area identification information after the terminal's location change. The first sensing function initiates a sensing network element reselection process based on the first information.

[0079] As another optional implementation, the first sensing function receiving the first information sent by the AMF may include: the first sensing function receiving the first information sent by the second AMF, wherein the first information includes at least the location identification information of the terminal after the location has changed; the second AMF is the AMF that serves the terminal after the location has changed.

[0080] In this embodiment, the AMF serving the terminal before and after its location changes is different: the first AMF serves the terminal before the location change, and the second AMF serves the terminal after the location change. It can be understood that before the terminal location changes, the first sensing function subscribes to the terminal's location change event from the first AMF via a first message; after the terminal location changes, the second AMF serves the terminal after the location change, and the second AMF notifies the first sensing function of the terminal's current location change event. That is, the first sensing function receives first information from the second AMF, which includes at least the area identification information after the terminal's location change. The first AMF can also send the first sensing function's subscription information for the terminal location change event to the second AMF. In this case, the first sensing function subscribes to subsequent location change events of the terminal from the second AMF.

[0081] Based on the foregoing embodiments, this embodiment of the invention also provides an information processing method, which will be described in detail for the switching process. Specifically, obtaining a second sensing function capable of providing sensing services to the terminal from a first network function may include: the first sensing function sending a second message to the first network function based on relevant information of the terminal, the second message being used to request a query of the second sensing function; the first sensing function receiving second information sent by the first network function, the second information including information of the second sensing function.

[0082] In this embodiment, the first sensing function carries relevant terminal information to the NRF to discover a second sensing function that can continue to provide sensing services to the terminal. Optionally, the relevant terminal information includes at least one of the following: slice identifier, region identifier information, and sensing service identifier. The region identifier information can be TAI and CELL ID.

[0083] In one embodiment, initiating a switchover to the second sensing function may include: the first sensing function sending a third message to the second sensing function, the third message being used to request the second sensing function to accept providing sensing services to the terminal. In this embodiment, the first sensing function sends a switchover request to the second sensing function based on the result returned by the NRF, requesting the second sensing function to undertake the sensing service task for the user.

[0084] Optionally, the method may further include: the first sensing function receiving a fourth message sent by the second sensing function, the fourth message being used to confirm providing sensing services to the terminal; the first sensing function sending third information to the second sensing function, the third information including at least relevant information for providing sensing services. This embodiment supports transmitting existing sensing data and related information to a target sensing function so that the target sensing function can continue to provide sensing services to the terminal.

[0085] In this embodiment, after the second sensing function confirms the response, the first sensing function begins transmitting relevant information. For example, the relevant information used to provide the sensing service includes at least one of the following: a sensing service identifier, sensing data, and a sensing data processing result. The sensing service identifier is used to distinguish the type of sensing service; the sensing data may be raw data obtained by the first sensing function from a sensing data provider; and the sensing data processing result is the processing result obtained by the first sensing function after analyzing the sensing data.

[0086] In one embodiment, the method may further include: the first sensing function receiving a fifth message sent by the second sensing function, the fifth message indicating that the handover is complete; the first sensing function sending a sixth message to the sensing service requester associated with the terminal, the sixth message notifying the sensing function providing the sensing service that it has switched from the first sensing function to the second sensing function. After the information transmission is completed, the second sensing function notifies the first sensing function that the handover has been completed, and the first sensing function notifies the sensing service requester that the sensing network element reselection is complete. Furthermore, after receiving the relevant information, the second sensing function may also notify the sensing service requester associated with the terminal to continue providing the sensing service.

[0087] Optionally, the method may further include: the first sensing function determining a corresponding sensing data provider based on the user information and area identification information of the terminal, and sending a ninth message to the sensing data provider, the ninth message being used to request unsubscribing from the collection of the sensing data. The sensing data is used by the first sensing function to provide corresponding sensing services to the terminal. After the sensing network element switch is completed, the first sensing function unsubscribing from the sensing data provider from the sensing data collection. The sensing data provider is a sensing execution network element that provides sensing data; specifically, it can be a base station or a non-3GPP sensing device, and this invention does not limit it.

[0088] This invention also provides an information processing method applied to a first sensing function. Figure 3 This is a flowchart illustrating the information processing method according to an embodiment of the present invention. Figure 2 ,like Figure 3 As shown, the method includes:

[0089] Step 201: The first sensing function receives a seventh message sent by the sensing service requester associated with the terminal, the seventh message being used to request the provision of sensing services to the terminal; the first sensing function provides sensing services to the terminal based on the obtained sensing data;

[0090] Step 202: The first sensing function receives first information sent by the AMF, the first information including at least the terminal's area identification information;

[0091] Step 203: If the first sensing function determines that it cannot provide sensing services to the terminal based on the first information, it obtains a second sensing function that can provide sensing services to the terminal from the first network function and initiates a switch to the second sensing function.

[0092] Step 204: The first sensing function receives a fifth message sent by the second sensing function, the fifth message indicating that the switch is complete; the first sensing function sends a sixth message to the sensing service requester associated with the terminal, the sixth message notifying the sensing function providing the sensing service that it has switched from the first sensing function to the second sensing function.

[0093] For a detailed explanation of steps 202 to 203 in this embodiment, please refer to the detailed explanation of steps 101 to 102 in the previous embodiment. To save space, they will not be repeated here.

[0094] In step 201, the sensing service requester associated with the terminal can be a network element within the 5GC, an application function outside the 5GC, or an external application, such as an application running on the terminal. The sensing service requester can discover the first sensing function via NRF and send a seventh message to the first sensing function to request the first sensing function to provide sensing services to the terminal. It should be noted that if the sensing service requester is an external application, it can be accessed through... Figure 1 The diagram shows the Network Exposure Function (NEF) and then the NRF to discover and sense functions.

[0095] Optionally, the first sensing function provides sensing services to the terminal based on the acquired sensing data, which may include: the first sensing function determining a corresponding sensing data provider based on the terminal's user information and region identification information, and sending an eighth message to the sensing data provider, wherein the eighth message is used to request subscription to the collection of the sensing data. The region identification information may be TAI and CELL ID.

[0096] In this embodiment, the first sensing function can discover sensing execution network elements (i.e., sensing data providers) that can provide sensing services to the terminal based on the user information and area identification information of the terminal carried by the protocol, and request to subscribe to sensing data collection from the sensing data provider. Further, the method may also include: step 205, the first sensing function sends a ninth message to the sensing data provider, the ninth message being used to request unsubscribing from the sensing data collection.

[0097] In step 204, after the information transmission is completed, the second sensing function notifies the first sensing function that the switchover has been completed. The first sensing function also notifies the sensing service requester that the sensing network element reselection is complete. Optionally, step 204 may further include: the second sensing function sending the sixth message to the sensing service requester, the sixth message being used to notify that the sensing function providing the sensing service has switched from the first sensing function to the second sensing function. That is, after the switchover is completed, the first sensing function and / or the second sensing function send the sixth message to the sensing service requester to notify that the sensing network element reselection is complete.

[0098] It should be noted that after the switch is completed, the second sensing function can discover a new sensing data provider based on the user information and area representation information of the terminal, and request to subscribe to sensing data collection. Based on the obtained sensing data, it provides sensing services to the terminal after the location change. At the same time, the second sensing function, as the first sensing function, re-executes the above steps 202 to 204. That is, the second sensing function obtains the first information sent by the AMF, and based on the first information, determines whether to continue to provide sensing services to the terminal after the location change, or to switch to a new sensing function to provide sensing services to the terminal after the location change.

[0099] This invention also provides an information processing method applied to AMF. Figure 4 This is a flowchart illustrating the information processing method according to an embodiment of the present invention. Figure 3 ,like Figure 4 As shown, the method includes:

[0100] Step 301: The AMF sends first information to the first sensing function, the first information including at least the terminal's area identification information; the first information is used to initiate a switch to the second sensing function that can provide sensing services to the terminal when the first sensing function determines that it cannot provide sensing services to the terminal.

[0101] Optionally, the AMF is the first AMF serving the terminal before and after the terminal location change; the method may further include: the first AMF receiving a first message sent by the first sensing function, the first message being used to request subscription to the terminal location change event. The first sensing function requests subscription to the terminal location change event from the first AMF through the first message.

[0102] In one embodiment, the AMF sending first information to the first sensing function includes: the first AMF sending the first information to the first sensing function, the first information including at least the area identification information after the terminal location changes. In this embodiment, after the terminal location changes, if the AMF serving the terminal is still the first AMF, then the first AMF sends the first information to the first sensing function.

[0103] In another embodiment, the AMF is a second AMF serving the terminal after the terminal location changes; the AMF sending first information to the first sensing function includes: the second AMF sending the first information to the first sensing function, the first information including at least the area identification information after the terminal location change. In this embodiment, after the terminal location changes, the AMF serving the terminal changes from the first AMF to the second AMF, then the first AMF sends the first information to the first sensing function.

[0104] In this embodiment, the method may further include: the second AMF receiving a tenth message sent by the first AMF, the tenth message including at least fourth information indicating a subscribed terminal location change event. That is, if the AMF changes, the first AMF sends location subscription information to the second AMF via the tenth message. Afterward, the sensing function will switch from subscribing to the terminal location change event from the first AMF to subscribing to the terminal location change event from the second AMF. The tenth message may be, for example, a Namf_Communication_CreateUEContext Request. Optionally, the tenth message may also include the terminal's region identification information, such as TAI and CELL ID.

[0105] The information processing scheme of this invention will be described below in conjunction with specific application scenarios.

[0106] Figure 5 An exemplary application process of the information processing scheme in this embodiment of the invention. Figure 1 This example addresses the scenario where the terminal's location changes but the AMF (Application Function) serving the terminal remains unchanged. Figure 5 As shown, the process includes:

[0107] The sensing service requester (or consumer (or Consumer NF)) discovers the sensing function (SF) and initiates an analysis request. When a user logs in normally, the Consumer NF discovers the sensing function providing the sensing service (e.g., [missing information]) through NRF. Figure 5In the context of SF1, the Consumer NF requests the provision of awareness services. If the Consumer NF is an external application, it sends a discovery request to the NRF via the NEF and receives a discovery response from the NRF via the NEF. The discovery response may include relevant information about SF1. Based on this relevant information, the Consumer NF sends an analysis request to SF1.

[0108] SF1 subscribes to sensing information collection requests from the source NF. SF1 can discover the sensing execution network element node (i.e., the source NF, which can be a base station or a non-3GPP sensing device) of the serving terminal and subscribe to sensing information collection requests based on the user information and location information carried in the protocol.

[0109] SF1 subscribes to user location change notifications from the AMF. SF1 also subscribes to UE location change events from the AMF.

[0110] When a user's location changes, the AMF notifies the SF1 of the user's location. In scenarios where the user moves, if the UE's location changes but the AMF remains unchanged or switched, the AMF will notify the SF1 of the user's location change, carrying key information such as the user's location (e.g., TAI+CELL ID).

[0111] SF Reselection. SF1 determines whether it can continue to provide sensing services based on the new user location. If not, it initiates the SF reselection process. SF1 carries relevant UE information (such as slice ID, location information, and sensing service ID) to the NRF to discover SF2, which can continue to provide services.

[0112] SF handover. Based on the results returned by NRF, SF1 sends a handover request to SF2, requesting SF2 to take over the sensing service tasks for this user; after SF2 confirms the response, it begins the transmission of relevant information (such as sensing ID, sensing data, sensing analysis information, etc.). After the information transmission is completed, SF2 notifies SF1 that the handover has been completed.

[0113] SF1 notifies Source NF to unsubscribe from the perception information collection request.

[0114] SF2 / SF1 notifies Consumer NF to complete SF reselection.

[0115] SF2 subscribes to requests for sensing information collection. SF2 discovers new SourceNFs based on user and location information. Figure 5 (Still shown as Source NF above) and continue to subscribe to the perception information collection request.

[0116] Figure 6 An exemplary application process of the information processing scheme in this embodiment of the invention. Figure 2 This example addresses a scenario where the terminal's location changes and the AMF (Application Function Name) serving the terminal also changes. Figure 6 As shown, the process includes:

[0117] The Consumer NF discovers the SF and initiates an analysis request. When a user logs in normally, the Consumer NF discovers SF1 via the NRF and requests awareness services. If the Consumer NF is an external application, it sends a discovery request to the NRF via the NEF to discover the SF, and receives the discovery response from the NRF via the NEF. The discovery response may include relevant information about SF1. Based on this information, the Consumer NF sends an analysis request to SF1.

[0118] SF1 subscribes to sensing information collection requests from the Source NF. SF1 can discover the sensing execution network element node (i.e., Source NF, which can be a base station or a non-3GPP sensing device) serving the UE based on the user information and location information carried in the protocol and subscribe to sensing information collection requests.

[0119] SF1 subscribes to user location change notifications. SF1 subscribes to UE location change events from AMF1.

[0120] When a user's location changes, the AMF (Application Function) is switched, and the UE context (UEcontext) is passed. If the UE's location changes while the user is moving, and the AMF changes or switches, the original AMF1 will send its location subscription information to the new AMF2 via the Namf_Communication_CreateUEContext Request, carrying key information such as the user's location (e.g., TAI+CELL ID).

[0121] The user's location will be notified to SF1. After the AMF handover process is completed, AMF2 will notify SF1 of the change in user location.

[0122] SF Reselection. SF1 determines whether it can continue to provide sensing services based on the new location information. If not, it initiates the SF reselection process. SF1 carries relevant UE information (such as slice ID, location information, and sensing service ID) to the NRF to discover SF2, which can continue to provide services.

[0123] SF handover. Based on the results returned by NRF, SF1 sends a handover request to SF2, requesting SF2 to take over the sensing service tasks for this user; after SF2 confirms the response, it begins the transmission of relevant information (such as sensing ID, sensing data, sensing analysis information, etc.). After the information transmission is completed, SF2 notifies SF1 that the handover has been completed.

[0124] SF1 cancels the subscription collection request. SF1 notifies Source NF to cancel the subscription awareness information collection request.

[0125] SF2 / SF1 notifies Consumer NF to complete SF reselection.

[0126] SF2 subscribes to requests for sensing information collection. SF2 discovers new SourceNFs based on user and location information. Figure 6 (Still shown as Source NF above) and continue to subscribe to the perception information collection request.
