[0034] Figure 1 shows a schematic diagram of the architecture of 5G network capacity exposure.

[0035] In the architecture diagram of capability exposure 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 exposes corresponding information to the AF according to the capability call request. The NEF interacts with other NFs (Network Functions, such as NF1, NF2 to NFn shown in Figure 1, where n is a positive integer greater than or equal to 1) of the 5G core network control plane via a service-based interface to obtain specific network information required by the AF.

[0036] In the method shown in FIG. 1, the network capabilities are exposed to the AF by the NEF. However, currently, the network capabilities that can be exposed do not include wireless network information, and capability exposure of wireless network information cannot be realized.

[0037] In addition, a problem of low-latency network information exposure has been proposed in the research topic of enhancing MEC (Multi-access Edge Computing). For example, some network information, such as network congestion information or real-time user plane delay, needs to be exposed to the application server in real time, so that the application server can perform corresponding application layer processing based on the information. If the retrieval delay of such network information is too long, the network information will be invalid, which will affect the subsequent optimization measures of the application layer.

[0038] Based on the technical problems existing in the above related art, the embodiments of the present application propose a network information exposure method.

[0039] 2 is a schematic diagram showing a flow chart of a network information exposure method according to an embodiment of the present application. The method provided in the embodiment of FIG. 2 may be performed by an electronic device, specifically, by the application function network element AF in FIG. 1.

[0040] As shown in FIG. 2, the method provided in the embodiment of the present application may include the following steps.

[0041] In step S210, a wireless network information exposure request is sent to a network exposure function network element, where the wireless network information exposure request carries an application function identifier of the application function network element and category information of target wireless network information, and the network exposure function network element transmits the category information and an application function address corresponding to the application function identifier to a base station, and the base station obtains the target wireless network information based on the category information, and sends the target wireless network information and the application function address to an anchor user plane function network element.

[0042] In the present embodiment, the application functionality identifier (AF identity) is abbreviated as AF ID.

[0043] In the embodiments of the present application, a base station is an interface device for mobile devices to access the Internet, and refers to a radio wave transmitting and receiving station that transmits information between mobile phone terminals and the mobile communication switching center in a certain radio wave coverage area. In the following embodiments, the base station is represented by a Radio Access Network (RAN), but the present application is not limited thereto.

[0044] In the embodiment of the present application, a wireless network information exposure request refers to a request message sent by an AF used to request exposure of wireless network information, the wireless network information for which exposure is requested is called target wireless network information, and the category information of the target wireless network information carried in the wireless network information exposure request is used to indicate the category to which the requested target wireless network information belongs, i.e., the target wireless network information matches the category information.

[0045] 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.

[0046] In an example embodiment, the radio network information exposure request may further include a target network slice and / or a target data network name, the target radio network information pertaining 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.

[0047] In the present embodiment, the target network slice and / or the target data network name carried in the radio network information exposure request may further indicate which or some specific sessions the requested target radio network information is for, and the specific sessions are hereinafter referred to as target sessions. The AF can know the target sessions through the radio network information exposure request. The sessions in the present embodiment include PDU (Protocol Data Unit) sessions.

[0048] Here, a network slice is used to realize on-demand networking, that is, an operator can separate multiple virtual end-to-end networks on a unified infrastructure, and each network slice can be logically or physically isolated from the radio access network, bearer network to the core network to meet different types of applications. A network slice can be divided into at least three parts: a radio network sub-slice, a bearer network sub-slice, and a core network sub-slice.

[0049] In an embodiment of the present application, the target network slice can be indicated by carrying a specific S-NSSAI (Single Network Slice Selection Assistance Information) in the radio network information exposure request.

[0050] In the wireless network information exposure request in the present embodiment, a specific Data Network Name (DNN), ie, the target data network name, is further carried.

[0051] In the embodiments of the present application, the radio network information refers to the capability information of the radio side, and may include, for example, PER information, access cell information, average data bit rate information, transmission delay of data packets between the UE and a UPF (User Plane Function) network element, network congestion information, or real-time user plane delay, etc.

[0052] In an exemplary embodiment, the wireless network information exposure request may further carry an information reporting manner, and the base station reports the target wireless network information according to the information reporting manner.

[0053] In an exemplary embodiment, if the information reporting manner is periodic reporting, the wireless network information exposure request may further carry a required information reporting period, and when the information reporting period is met, the base station reports the target wireless network information according to the information reporting period.

[0054] In an exemplary embodiment, if the information reporting manner is an event trigger, the wireless network information exposure request may further carry a defined event, and when the defined event is met, the base station reports the target wireless network information based on the event trigger, where the defined event is, for example, a threshold, an event reporting count, etc.

[0056] In an exemplary embodiment, the wireless network information exposure request may further carry requested coverage information, and the step of obtaining the target wireless network information returned by the anchor user plane function network element based on the application function address specifically includes receiving target wireless network information satisfying the requested coverage information from a network exposure function network element, where the requested coverage information is, for example, information on a specific UE, a group of UEs, or all UEs, a specific time period, a specific geographical area, etc.

[0057] In an exemplary embodiment, if the requested coverage information includes a target user equipment identifier, receiving the target wireless network information satisfying the requested coverage information from the anchor user plane function network element specifically includes receiving target wireless network information of a 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 exposure request applies to a specific UE, and the specific UE is referred to as a target UE.

[0058] In an example embodiment, if the requested coverage information includes a target user equipment group identifier, receiving the target radio network information satisfying the requested coverage information from the anchor user plane function network element specifically includes receiving target radio network information of 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 exposure request applies to a specific UE group, the specific UE group is referred to as a target UE group, and the UE in the specific UE group is referred to as a target UE.

[0059] In an exemplary embodiment, if the requested coverage information includes target period information, the step of receiving the target wireless network information that satisfies the requested coverage information from the anchor user plane function network element specifically includes a step of receiving target wireless network information of the target user equipment that satisfies the target period information.

[0060] In an exemplary embodiment, if the requested coverage information includes target geographic range information, receiving the target wireless network information satisfying the requested coverage information from the anchor user plane function network element specifically includes receiving target wireless network information of a target user equipment located within a target geographic range corresponding to the target geographic range information, where the target geographic range information is used to indicate that the wireless network information exposure request applies to a specific geographic range, and the specific geographic range is referred to as a target geographic range.

[0061] In an exemplary embodiment, obtaining the target wireless network information returned by the anchor user plane function network element based on the application function address may include receiving a network data packet from an anchor user plane function network element, the network data packet carrying target wireless network information, a target user equipment address, a destination address, and a source address, where the network data packet is generated by the anchor user plane function network element based on the radio access network exposure information container sent by an intermediate user plane function network element or a base station.

[0062] That is, the anchor user plane network element may receive a radio access network exposure information container from a base station, or may receive the radio access network exposure information container sent by the base station from an intermediate user plane network element, where the target radio network information and the application function address are included in the radio access network exposure information container.

[0063] In an exemplary embodiment, the destination address is the application function address and the source address is an anchor user plane function address of an anchor user plane function network element.

[0064] In an exemplary embodiment, the network data packet may further include radio access network exposure information packet header information, and the radio access network exposure information packet header information may indicate that the target wireless network information is included in the network data packet.

[0065] In an exemplary embodiment, the target wireless network information is encapsulated in a wireless access network exposure information container in a data exchange format or code flow manner, where the data exchange format may be JSON (JavaScript Object Notation) format, which is a kind of lightweight-level data exchange format.

[0066] The embodiments of the present application 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 with reference to the following examples.

[0067] The AF in the embodiment of the present application may support requesting exposure of wireless network information (called target wireless network information) of a specific session from the NEF, such as PER information, access cell information, average data bit rate information, and so on.

[0068] Specifically, the AF may send a radio network information exposure request to the NEF, where the radio network information exposure request 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 trigger).

[0069] Here, the specific 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 a request for exposure of PER information, "2" is used to indicate a request for exposure of access cell information, "3" is used to indicate a request for exposure of average data bit rate information, etc.

[0070] In the embodiment of the present application, the NEF is used to receive a wireless network information exposure request sent by the AF, where the NEF receives the information as a kind of monitoring capability, and as a kind of parameter type information that the new network can expose, i.e., wireless network information.

[0071] The NEF can encapsulate the information as a radio access network exposure request container, where the radio access network exposure request container includes: 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.; The information may include information on the information reporting method.

[0072] In addition, the NEF can also send a subscribe request to the SMF to subscribe to the notification message of the SMF. When the SMF establishes a target session corresponding to the target DNN and / or the target network slice, it can send a notification message to the NEF to inform the NEF of the information of the target UE, for example, including an identifier of a QoS flow (referred to as a target quality of service flow identifier).

[0073] When the NEF receives the notification message sent by the SMF, it knows that it has established a target session that meets the conditions, and the NEF sends a radio access network exposure request container to the AMF, which can then send it to the base station via the N2 message.

[0074] Determining whether a target session that satisfies a condition has been established can be determined based on information carried in the wireless network information exposure request, for example, satisfying a target network slice and / or a target DNN.

[0075] Further, for example, if there is a specific geographical range restriction in the radio network information exposure request sent by the AF, only when a target UE in the specific geographical range establishes a target session that meets the condition, the SMF can send the above notification message to the NEF, and then the NEF can send a radio access network exposure request container to the AMF serving the target UE, and the AMF transparently transmits the radio access network exposure request container to the base station.

[0076] In the embodiment of the present application, the AMF is used to receive a radio access network exposure request container sent by the NEF, and transparently transmit the radio access network exposure request container to a base station serving the target UE.

[0077] In an embodiment of the present application, a base station is used to receive a radio access network exposure request container sent by an AMF, and the base station can configure the radio access network exposure request container in the target QoS flow of the target UE.

[0078] When the base station detects the RAN side information of the target QoS flow of the target UE and meets a reporting condition (e.g., meets a reporting periodicity requirement or meets an event), the base station can send the requested target wireless network information to the intermediate UPF via the N3 interface, and then finally to the anchor UPF via the N9 interface. The base station can also send the requested target wireless network information directly to the anchor UPF via the N3 interface. The target wireless network information and the application function address exposed by the RAN can be encapsulated in a radio access network exposure information container.

[0079] After the anchor UPF encapsulates the IP (Internet Protocol) address of the target UE (called the target user equipment address) into a network data packet including a radio access network exposure information container, the anchor UPF can set the address of the AF (application function address) to the destination IP address (i.e., destination address) of the corresponding network data packet, set the address of the anchor UPF (called the anchor user plane function address) to the source address of the network data packet, and send the network data packet to the AF.

[0080] In an embodiment of the present application, the anchor UPF can encapsulate REI (RAN exposure information) packet header information in the network data packet, and the REI packet header information can be used to indicate that target wireless network information is encapsulated in the network data packet.

[0081] In an embodiment of the present application, when the AF receives target wireless network information for which exposure is required, it can expose it to an application server in real time, and the application server can perform corresponding application layer processing based on the target wireless network information, for example, if the exposed target wireless network information includes network congestion information or real-time user plane delay, it can adjust the video resolution or change the level of autonomous driving, etc., that is, optimize the application layer.

[0082] The network information exposure method provided in the embodiment of the present application, on the one hand, sends a wireless network information exposure request by an application function network element to a network exposure function network element, the wireless network information exposure request carries category information of target wireless network information and an application function identifier of the application function network element, can allow a base station to obtain the requested target wireless network information based on the category information, and further sends the target wireless network information obtained by the base station back to the application function network element from which the wireless network information exposure request was sent by the anchor user plane function network element, thereby realizing the exposure ability of wireless network information; on the other hand, can reduce the delay of wireless network information exposure and meet the low-latency requirement of application layer processing.

[0083] The method provided in the above embodiment will now be described by way of example in conjunction with FIG.

[0084] FIG. 3 illustrates a schematic diagram of an interaction of a network information exposure method according to another embodiment of the present application.

[0085] As shown in FIG. 3, in step S1, the AF requests network wireless capability exposure information (ie, target wireless network information) from the NEF.

[0086] In an embodiment of the present application, the AF requests the NEF to expose network wireless capability information of a specific session (target session), and the AF can send a wireless network information exposure request to the NEF, where the wireless network information exposure request may include an AF ID, indication information of the specific wireless network information (e.g., category information of the target wireless network information), a specific network slice, a specific DNN, an information reporting manner (periodic reporting, event trigger), etc.

[0087] The AF may further indicate the scope of the radio network information exposure request in the radio network information exposure request, i.e., carry requested scope information, such as a specific UE, a specific group of UEs, or all UEs, a specific time period, a specific geographical area, etc.

[0088] In the embodiment of the present application, when the NEF receives the wireless network information exposure request sent by the AF, the NEF can perform authentication on the wireless network information exposure request sent by the AF according to the operator's policy and the protocol between the operator and the AF (called the application function protocol). When the authentication is successful, the NEF can accept the wireless network information exposure request sent by the AF and return a request acceptance response message to the AF, i.e., the response message indicates that the wireless network information exposure request is accepted; when the authentication is unsuccessful, the NEF can reject the wireless network information exposure request sent by the AF and return a request rejection response message to the AF, i.e., the response message indicates that the wireless network information exposure request is rejected, and a rejection reason value may be included.

[0089] In step S2, the NEF subscribes to notification messages of a particular session to the SMF.

[0090] In an embodiment of the present application, the NEF can subscribe to a notification message of a specific session to the SMF based on information carried in a radio network information exposure request sent by the AF, and the subscription request sent by the NEF to the SMF may include the specific DNN or the specific network slice carried in the radio network information exposure request, and optionally may further include a specific UE identifier, or a specific UE group identifier, or specific time information, or specific geographical area information.

[0091] Here, when a specific UE identifier is not included in the subscribe request, the subscribe request is valid for all UEs, and when a specific UE identifier or a specific UE group identifier is included in the subscribe request, the subscribe request is only valid for a specific UE or a specific UE group.

[0092] When specific time information is included in the subscribe request, the SMF will send a notification message to the NEF only when it fulfills the subscribe request within a target period indicated by the specific time information.

[0093] When specific geographical range information is included in the subscribe request, the SMF will send a notification message to the NEF only when a target UE within the specific geographical range satisfies the subscribe request.

[0094] Based on the subscribe request, when the target UE establishes a target session to a specific DNN or a specific network slice and simultaneously meets other requirements (such as the above-mentioned specific time information), the SMF can send a notification message to the NEF.

[0095] In an embodiment of the present application, the notification message may include a target UE identifier (target user equipment identifier), an AMF identifier (access and mobility management function identifier), a PDU session identifier (i.e., a target session identifier), and a QoS flow identifier (i.e., a target quality of service flow identifier), etc.

[0096] In step S3, the NEF requests network wireless capability exposure information (i.e., target wireless network information) from the AMF.

[0097] The NEF may encapsulate the radio network information exposure request received from the AF as a radio access network exposure request container, and send the radio access network exposure request container, a target UE identifier, a PDU session identifier, a QoS flow identifier, etc. to the AMF.

[0098] In step S4, the AMF sends a network radio capability exposure request message to the RAN.

[0099] The AMF may encapsulate the radio access network exposure request container, the target UE identifier, the PDU session identifier, and the QoS flow identifier, etc., into a network radio capability exposure request message, and then send it to the base station.

[0100] In step S5, the RAN sends target wireless network information that meets the reporting condition to the AMF.

[0101] After accepting the radio network information exposure request, the base station can set the radio access network exposure request container to the target QoS flow of the target UE. When a reporting condition is detected to be met, the base station can encapsulate the exposed target radio network information and the application function address into a radio access network exposure information container, and finally send the radio access network exposure information container to an anchor UPF (anchor user plane function network element) of a PDU session (i.e., a target session) corresponding to the PDU session identifier.

[0102] In step S6, the anchor UPF sends the target wireless network information to the AF.

[0103] The anchor UPF can encapsulate the radio access network exposure information container into an IP data packet (i.e., a network data packet), and encapsulate the UE's IP address (i.e., the target user equipment address) into the network data packet in which the radio access network exposure information container is included, and further set the destination address of the IP data packet to the address of the AF, and set the source address to the address of the anchor UPF (i.e., the anchor user plane function address). The anchor UPF sends the IP data packet to the AF.

[0104] In the embodiment of the present application, the anchor UPF may send the IP data packet directly to the AF, or may send the IP data packet to the AF via the NEF.

[0105] The network information exposure method provided in the embodiment of the present application encapsulates a radio access network exposure information container in a data packet specific to a base station, so that the target radio network information that can be exposed can be sent to an anchor UPF via the radio access network exposure information container, and then sent to an AF via the anchor UPF, which on the one hand can realize the exposure of radio network information, and on the other hand can reduce the delay of radio network information exposure and meet the low-latency requirements of application layer processing.
