For example, the electronic device can perform various steps as shown in Figure 2, Figure 3, Figure 4, Figure 5, or Figure 6.

[0030] FIG. 1 is a schematic diagram showing the architecture of 5G network capability opening.

[0031] In the diagram of the capability release architecture shown in Figure 1, a NEF (Network Exposure Function) network element interacts with an AF (Application Function) network element via an N33 interface to obtain a capability call request of the AF, and releases corresponding information to the AF according to the capability call request. The NEF interacts with other NFs (Network Functions, for example, NF1, NF2 to NFn, n is a positive integer equal to or greater than 1, shown in Figure 1) in the 5G core network control plane via a service-enabled interface to obtain specific network information required by the AF.

[0032] In the scheme shown in FIG. 1, network capabilities are opened to the AF via the NEF. However, currently, the openable network capabilities do not include wireless network information, and it is not possible to realize the opening of capabilities of wireless network information.

[0033] In addition, the research topic of strengthening MEC (Multi-access Edge Computing) proposes releasing network information with low latency. Some network information, such as network congestion information or real-time user plane delay, needs to be exposed to application servers in real time, so that the application servers can perform corresponding application layer processing based on the information. If the call time of such network information is too long, the network information will become invalid, which will affect the optimization scheme of the subsequent application layer.

[0034] In view of the technical problems existing in the related art mentioned above, an embodiment of the present invention provides a method for opening network information.

[0035] 2 is a flow chart illustrating an example of a method for releasing network information according to an embodiment of the present invention. The method according to the embodiment of FIG. 2 may be performed by an electronic device, specifically, by the application function network element AF in FIG. 1.

[0036] As shown in FIG. 2, the method according to an embodiment of the present invention may include the following steps.

[0037] In step S210, the network opening function network element transmits category information of the target wireless network information to the base station, and the base station obtains the target wireless network information based on the category information, and sends a wireless network information opening request carrying the category information to the network opening function network element, so as to send the target wireless network information to the network opening function network element.

[0038] In the embodiment of the present invention, the base station is an interface device for a mobile device to access the Internet, and refers to a radio transceiver station that transmits information to and from a mobile telephone terminal via a mobile communication switching center in a certain radio coverage area. In the following embodiment, the base station is represented by a Radio Access Network (RAN), but the present invention is not limited thereto.

[0039] In the embodiment of the present invention, the wireless network information release request refers to a request message sent by an AF to request for release of wireless network information. The wireless network information requested to be released is called target wireless network information. The category information of the target wireless network information carried in the wireless network information release request is used to indicate the category to which the requested target wireless network information belongs, that is, the target wireless network information matches the category information.

[0040] In an exemplary embodiment, the category information of the target wireless network information may include at least one of packet error ratio (PER) information, access cell information, and average data bit rate information.

[0041] In an example embodiment, the radio network information release request may further include a target network slice and / or a target data network name, where the target radio network information, in addition to matching the category information, belongs to a target Quality of Service Flow (QoS Flow) of a target User Equipment (UE) that establishes a target session based on the target network slice and / or the target data network name.

[0042] In an embodiment of the present invention, the target network slice and / or the target data network name carried in the radio network information release request may further indicate which session or which specific session the requested target radio network information is for. The specific session is hereinafter referred to as the target session. The AF can know the target session through the radio network information release request. The session in the embodiment of the present invention includes a PDU (Protocol Data Unit) session.

[0043] Here, a network slice is used to realize on-demand network grouping, that is, a provider separates multiple virtual end-to-end networks in a unified infrastructure, and logically or physically isolates each network slice from a radio access network, a carrier network to a core network, to accommodate various types of applications. A network slice can be divided into at least three parts: a radio network sub-slice, a carrier network sub-slice, and a core network sub-slice.

[0044] In an embodiment of the present invention, the target network slice can be indicated by carrying a specific S-NSSAI (Single Network Slice Selection Assistance Information) in the radio network information release request.

[0045] The wireless network information release request in the embodiment of the present invention further carries a specific Data Network Name (DNN), ie, the target data network name.

[0046] In an embodiment of the present invention, the wireless network information means wireless side capability information, and may include, for example, PER information, access cell information, average data bit rate information, transmission delay of data packets between a UE and a UPF (User Plane Function) network element, network congestion information, or real-time user plane delay, etc.

[0047] In an exemplary aspect, the wireless network information release request may further carry an information reporting scheme, and the base station reports the target wireless network information according to the information reporting scheme.

[0048] In an exemplary aspect, when the information reporting manner is periodic reporting, the wireless network information release request may further carry an information reporting period. If the information reporting period is met, the base station reports the target wireless network information according to the information reporting period.

[0049] In an exemplary aspect, when the information reporting manner is an event trigger, the wireless network information release request may further carry a defined event. When the defined event is met, the base station reports the target wireless network information according to the event trigger. Here, the defined event is, for example, a threshold, a number of reporting events, etc.

[0050] In step S220, obtain the target wireless network information returned by the network opening function network element.

[0051] In an exemplary aspect, the wireless network information release request may further carry requested coverage information. Obtaining the target wireless network information returned by the network release function network element includes receiving the target wireless network information satisfying the requested coverage information from the network release function network element, where the requested coverage information is, for example, information for a specific UE, a group of UEs or all UEs, a specific time period, a specific geographical area, etc.

[0052] In an exemplary aspect, if the requested coverage information includes a target user equipment identifier, receiving target wireless network information satisfying the requested coverage information from the network opening function network element includes receiving target wireless network information of the target user equipment corresponding to the target user equipment identifier, where the target user equipment identifier is used to indicate that the wireless network information opening request applies to a specific UE, and the specific UE is referred to as a target UE.

[0053] In an exemplary aspect, if the requested coverage information includes a target user equipment group identifier, receiving target radio network information satisfying the requested coverage information from the network opening function network element includes receiving target radio network information of a target user equipment in a target user equipment group corresponding to the target user equipment group identifier, where the target user equipment group identifier is used to indicate that the radio network information opening request applies to a specific UE group, the specific UE group is referred to as a target UE group, and a UE in the specific UE group is referred to as a target UE.

[0054] In an exemplary aspect, when the requested coverage information includes target period information, receiving target wireless network information that satisfies the requested coverage information from the network opening function network element includes receiving target wireless network information of the target user device that satisfies the target period information.

[0055] In an exemplary aspect, when the requested coverage information includes target geographical range information, receiving target wireless network information satisfying the requested coverage information from the network opening function network element includes receiving target wireless network information of a target user device in a target geographical range corresponding to the target geographical range information, where the target geographical range information is used to indicate that the wireless network information opening request applies to a specific geographical range, and the specific geographical range is referred to as a target geographical range.

[0056] In an example aspect, obtaining the target wireless network information returned by the network opening function network element may include receiving a radio access network opening information container carrying the target wireless network information from the network opening function network element, where the radio access network opening information container was received by the network opening function network element from the base station via an Access and Mobility Management Function (AMF) network element.

[0057] In an exemplary aspect, the target wireless network information is encapsulated in a wireless access network opening information container in a data exchange format or code stream manner, where the data exchange format may be a JavaScript Object Notation (JSON) format, which is a lightweight data exchange format.

[0058] The embodiments of the present invention enhance the functions of the AF, NEF, AMF (Access and Mobility Management Function) network element, SMF (Session Management Function) network element, and base station, and are described below by way of examples.

[0059] The AF in the embodiment of the present invention can support wireless network information (referred to as target wireless network information) that requests the NEF to release a specific session, such as PER information, access cell information, average data bit rate information, etc.

[0060] Specifically, the AF may send a radio network information release request to the NEF, which may include a specific radio network information request, a specific network slice (i.e., a target network slice) and / or a specific DNN (i.e., a target DNN), and an information reporting scheme (e.g., periodic reporting or event triggering).

[0061] Here, a particular wireless network information request may be indicated by a category identifier of the requested target wireless network information, for example, "1" is used to indicate requesting release of PER information, "2" is used to indicate requesting release of access cell information, "3" is used to indicate requesting release of average data bit rate information, etc.

[0062] In an embodiment of the present invention, the NEF receives a wireless network information release request sent by the AF, where the NEF may receive the information as one of monitoring capabilities and parameter types that the new network can release, i.e., wireless network information.

[0063] The NEF may encapsulate the information into a radio access network exposure request container, where the radio access exposure request container may include the following information:

[0064] Category information of target wireless network information requested by the AF side, such as PER information, access cell information, average data bit rate information, etc. ·Information reporting method The NEF may also send a subscription request to the SMF to subscribe to a notification message of the SMF. The SMF may also send a notification message to the NEF to notify the NEF of information of the target UE, including, for example, an identifier of a QoS flow (referred to as a target quality of service flow identifier), when establishing a target session corresponding to the target DNN and / or the target network slice.

[0065] After receiving the notification message sent by the SMF, the NEF knows that a target session that meets the conditions has been established, and the NEF may send a radio access network release request container to the AMF, to be sent by the AMF to the base station via an N2 message.

[0066] The determination of whether a target session that satisfies the conditions has been established may be determined based on information carried by the wireless network information release request, for example to satisfy the target network slice and / or the target DNN.

[0067] Also, for example, if the radio network information release request sent by the AF has a specific geographical range restriction, the SMF will only send the above notification message to the NEF when a target UE in the specific geographical range establishes a target session that meets the condition.The NEF may then send a radio access network release request container to the AMF serving the target UE, and the AMF forwards the radio access network release request container to the base station.

[0068] In an embodiment of the present invention, the AMF receives a radio access network release request container sent by the NEF, and forwards the radio access network release request container to a base station serving the target UE.

[0069] In an embodiment of the present invention, a base station receives a radio access network release request container sent by an AMF, and the base station may configure the radio access network release request container in a target QoS flow of the target UE.

[0070] When the base station detects the RAN side information and meets the reporting condition (e.g., meets the information reporting period requirement or event definition), the base station may send the requested target radio network information to the AMF via the N2 interface. The target radio network information released by the RAN may be encapsulated in a radio access network release information container.

[0071] When the AMF receives the radio access network release information container sent by the RAN, the AMF may forward the radio access network release information container to the NEF.

[0072] In an embodiment of the present invention, after receiving the target wireless network information that is requested to be released, the AF may release it to the application server in real time. The application server may perform corresponding application layer processing based on the target wireless network information. For example, if the released target wireless network information includes network congestion information or real-time user plane delay, the application server may adjust the video resolution or change the level of autonomous driving, that is, optimize the application layer.

[0073] In an embodiment of the present invention, the wireless network information release request may further carry a capability release association identifier, which associates each wireless network information release request with the AF that sends the wireless network information release request. When the NEF receives the wireless network information release request, it may store a mapping relationship between the wireless network information release request and the capability release association identifier. In this way, when the NEF subsequently receives the target wireless network information returned by the AMF, it may search for the AF that sent the wireless network information release request according to the mapping relationship, so that the target wireless network information can be returned to the corresponding AF.

[0074] For example, the capability release association identifier may be any one or more of a string uniquely encoded for each wireless network information release request, an application function identifier (AF identity, abbreviated as AF ID) of the application function network element AF, or an address of the AF, and the present invention is not limited thereto.

[0075] In the network information release method according to the embodiment of the present invention, an application function network element sends a wireless network information release request to a network release function network element, and the wireless network information release request carries category information of target wireless network information. Therefore, a base station obtains the requested target wireless network information according to the category information of the target wireless network information, and then uses the network release function network element to return the target wireless network information obtained by the base station to the application function network element that sent the wireless network information release request. This realizes the release capability of wireless network information. Meanwhile, the delay of wireless network information release can be reduced, and the low delay requirement of application layer processing can be met.

[0076] The following provides an illustrative description of the method according to the above embodiment with reference to FIG.

[0077] FIG. 3 is a schematic diagram illustrating an example of interaction of a network information release method according to one embodiment of the present invention.

[0078] As shown in FIG. 3, in step S1, the AF requests network wireless capability opening information (ie, target wireless network information) from the NEF.

[0079] In an embodiment of the present invention, the AF requests the NEF to release network wireless capability information of a specific session (target session). The AF may send a wireless network information release request to the NEF. The wireless network information release request may include an AF ID, indication information of specific wireless network information (e.g., category information of target wireless network information), a specific network slice, a specific DNN, information reporting manner (periodic reporting, event triggering), etc.

[0080] In the radio network information release request, the AF may further indicate the scope of the radio network information release request, i.e., may carry request scope information, such as a specific UE, a specific UE group or all UEs, a specific period, a specific geographical area, etc.

[0081] In an embodiment of the present invention, after the NEF receives the wireless network information release request sent by the AF, the NEF may authenticate the wireless network information release request sent by the AF based on the provider's policy and the protocol between the provider and the AF (referred to as the application function protocol). If the authentication is successful, the NEF may approve the wireless network information release request sent by the AF and return a request approval response message to the AF, i.e., indicate in the returned response message that the wireless network information release request is approved. If the authentication is not successful, the NEF may reject the wireless network information release request sent by the AF and return a request rejection response message to the AF, i.e., indicate in the returned response message that the wireless network information release request is rejected, and include a rejection reason value.

[0082] In step S2, the NEF subscribes to notification messages for a specific session to the SMF.

[0083] In an embodiment of the present invention, the NEF may subscribe to a notification message of a specific session to the SMF based on information carried in a radio network information release request sent by the AF. The subscription request sent by the NEF to the SMF may include a specific DNN or a specific network slice carried in the radio network information release request. Preferably, the subscription request may further include a specific UE identifier, a specific UE group identifier, specific time information, or specific geographical range information.

[0084] Wherein, if the subscription request does not include a specific UE identifier, the subscription request is valid for all UEs, whereas if the subscription request includes a specific UE identifier or a specific UE group identifier, the subscription request is only valid for a specific UE or a specific UE group.

[0085] If the subscription request includes specific time information, the SMF sends a notification message to the NEF only when the subscription request is fulfilled within the target period indicated by the specific time information.

[0086] If the subscription request includes specific geographical range information, the SMF sends a notification message to the NEF only when a target UE within the specific geographical range satisfies the subscription request.

[0087] In response to the subscription request, if the target UE establishes a target session for a specific DNN or a specific network slice and meets other requirements (e.g., the specific time information mentioned above), the SMF may send a notification message to the NEF.
