Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In a 4G (fourth generation mobile communication technology) mobile network, a network is in a black box state for an application service on a user side, and the application service on the user side can use the network but cannot perform any operation on the network. In a 5G (fifth generation Mobile communication technology) network, an application service may interact with the 5G network through an Edge Computing node (MEC). For example, the application server may direct traffic accessing the mobile network through the edge computing node.

In the prior art, the device at the application side cannot sense the service capability of the user plane functional network element in the mobile network, so that the interaction with the mobile network is not facilitated. In view of the above technical problems, in some embodiments of the present application, a solution is provided, and the technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Fig. 1a is a schematic flowchart of a network element information processing method according to an embodiment of the present application. As shown in fig. 1a, the method comprises:

step 101, analyzing network elements by network data of a core network in a mobile network, and acquiring specific network element information from a target network element; wherein the target network element comprises: a network element associated with a service capability of at least one user plane function network element.

Step 102, obtaining the service capability information of each user plane function network element according to the network element information of the target network element.

Step 103, opening the service capability information of the at least one user plane functional network element to the device at the application side.

The embodiment can be applied to 5G, 5.5G or 6G mobile networks. In a Core Network of a mobile Network, for example, a 5G Core Network (5G Core Network, 5GC), various Network elements (i.e., functional entities in the Core Network) may be deployed.

For example, when the mobile communication network is implemented as a 5G network, the network elements of the 5G core network deployed on the hardware device may include, but are not limited to, the following network functions and entities: network elements such as an Authentication Server Function (AUSF), a User Plane Function (UPF), an Access and Mobility Management Function (AMF), a Unified Data Management (UDM), a Network open Function (NEF), a Session Management Function (SMF), a Network Slice Selection Function (NSSF), a Network storage Function (NF playback Function, NRF), a Policy Control Function (Policy Control Function, PCF), and an Application layer Function (AF).

In addition to the above general-purpose NetWork elements, in this embodiment, a NetWork Data analysis (NWDAF) NetWork element may also be deployed in a core NetWork of the mobile NetWork, as shown in fig. 1 b. The network data analysis network element is used for extracting, analyzing, distributing and the like the network element data. The core network may execute the network element information processing method provided in this embodiment based on the network data analysis network element.

In this embodiment, the NWDAF network element may obtain specific network element information of the target network element. The target network element may include a network element associated with a service capability of a UPF (User Panel Function, UPF) network element in a core network of the mobile network. Typically, a communication connection exists between the target network element and the UPF. When a plurality of UPF network elements exist in the mobile network, specific network element information can be respectively obtained from target network elements corresponding to the plurality of UPF network elements.

Wherein, the specific network element information in the target network element is used for describing relevant characteristics of the UPF, such as location characteristics, load characteristics, time delay characteristics, hardware resource characteristics, and the like of the UPF. In this embodiment, the relevant information capable of reflecting the service capability of the UPF network element may be obtained from the specific network element information of the target network element. The service capability of the UPF refers to the capability of the UPF to provide a specified class of service to a device on the application side (e.g., a server or a user terminal on the application side). Such as the area service capability, traffic load capability, access pressure capability, etc. of the UPF.

In some embodiments, the target network element may comprise: at least one of a UPF network element, a SMF network element, a PCF network element and a UDM network element. When one UPF network element is in communication connection with one or more SMF network elements, the NWDAF network element may obtain network element information of each of the one or more SMF network elements. When a UPF network element is in communication connection with one or more PCF network elements, the NWDAF network element can acquire the respective network element information of the one or more PCF network elements; similarly, when one UPF network element is in communication connection with one or more UDM network elements, the NWDAF network element may obtain respective network element information of the one or more UDM network elements.

In some embodiments, a UPF network element that needs to open service capability to the application side may register in advance at the NWDAF network element. Each UPF network element may be provided with information related to the target network element associated with the UPF network element, such as a listening interface, an access address, and the like, when registering. Further, the NWDAF network element may obtain the service capability of the UPF registered in the NWDAF network element based on the registration information.

The NWDAF network element may dynamically subscribe to specific network element information of the target network element according to a set period. The set period may be set according to requirements, and may be, for example, 1 hour, 6 hours, 12 hours, 24 hours, and the like, which is not limited in this embodiment. The NWDAF network element may also obtain specific network element information of the target network element under the trigger of the set trigger event. The set triggering event may be a user event or a system event, and this embodiment is not limited. Based on the implementation, the NWDAF network element can dynamically acquire the service capability of the UPF network element, and the dynamically acquired service capability is closer to the real service capability of the UPF network element.

After the NWDAF network element obtains the network element information of the target network element, the network element information of the target network element can be directly used as the service capability information of each UPF network element. Or, after the NWDAF network element obtains the network element information of the target network element, the NWDAF network element may analyze the network element information of the target network element by using a set algorithm to extract the service capability information of the at least one UPF network element. Or, the NWDAF network element may send the network element information of the target network element to the cloud server, so that the cloud server extracts the network element information of the target network element, and returns the extracted service capability information of each of the at least one user plane function network element to the NWDAF network element, which is not limited in this embodiment.

When the network element information of the target network element is extracted, information containing a specific keyword is extracted from the obtained network element information, or information of part of specified fields can be extracted from the network element information of the target network element. Besides the above manner, a machine learning model (e.g., hidden markov model, maximum entropy markov model, conditional random field, voting perceptron model, etc.) may be used to extract the service capability information, which is not described herein.

The service capability information of the UPF network element may include, but is not limited to, new information such as location, load, performance, delay, and number of users of the UPF network element. The information can reflect the capacity of the UPF network element for providing the service to the application server, and based on the service capacity information, the capacity of the UPF network element for providing the service can be opened for the device (such as the application server) at the application side, so that the device at the application side can select the adaptive UPF network element.

After obtaining the service capability information of the at least one UPF network element, the NWDAF network element may store the service capability information for subsequent use. In some embodiments, the nwdf network element may store the respective service capability information of the at least one UPF network element locally; in other embodiments, the NWDAF network element may store the service capability information of the at least one UPF network element in the source network element of the information, which is not limited in this embodiment.

In this embodiment, the NWDAF network element may open the service capability information of the at least one UPF network element to the device on the application side. The device at the application side may include any device that has a requirement for sensing the UPF service capability, including but not limited to a terminal device or a server device at the application side, which is not limited in this embodiment.

The method for the NWDAF network element to open the service capability information of the at least one UPF network element may include: and when the service capability information of the at least one UPF network element is obtained by calculation each time, sending the service capability information of the at least one UPF network element to the user side equipment subscribed with the information. Or, according to a certain period, sending the service capability information of at least one UPF network element calculated in the period range to the user side equipment subscribing to the information. Or, the service capability information of the at least one UPF network element may be sent to the user side equipment subscribed to the information according to a request of the user side equipment, which is not limited in this embodiment.

In this embodiment, the data analysis network element deployed in the mobile network may dynamically acquire the network element information from the target network element associated with the service capability of the user plane functional network element, extract the service capability information of the user plane functional network element from the network element information, and open the service capability information of the user plane functional network element to the device on the application side. The service capability information of the user plane function network element can provide a data base for the interaction between the application server and the mobile network, and is favorable for optimizing the interaction capability between the equipment at the user side and the mobile network.

In some exemplary embodiments, the service capability of the UPF network element may be used as a basis for directing traffic that accesses the mobile network.

Optionally, the NWDAF network element may receive a selection request of the UPF network element sent by the application server, and return the acquired service capability information of at least one UPF network element to the application server according to the request. Further, the application server may select the target UPF network element based on the service capability information of the at least one UPF network element. The target UPF network element is used for traffic steering operations, i.e., the server can steer the user's access traffic onto the target UPF network element.

The application server may be an MEC (Mobile Edge Computing) server or a DN server, which is not limited in this embodiment.

As shown in fig. 1b, optionally, the application server (i.e., the MEC server or the DN server) may obtain the service capability information of the at least one UPF from the NWDAF network element through the NEF network element; alternatively, the service capability information of the at least one UPF may also be directly acquired from the NWDAF, which is not limited in this embodiment.

In some embodiments, the service capability information of the UPF network element, which may be returned by the NWDAF network element to the application server, may be general service capability information of the UPF network element. In other embodiments, if the application server initiating the selection request of the UPF network element is a server of a certain application (e.g., a server of application a), the NWDAF network element may return service capability information of the UPF network element for the application (e.g., application a) to the application server.

As shown in fig. 1c, after receiving the service capability information of the at least one UPF network element, the application server (MEC server or DN server) may select a target UPF according to the service capability information of the at least one user plane function network element, and send the selected target UPF to the NWDAF network element. The target UPF network element is used for bearing the traffic guided by the first application server subsequently, thereby realizing dynamic traffic guiding.

In this embodiment, therefore, when the application server has a requirement for selecting the user plane function, the application server may obtain the service capability information of the UPF network element from the NWDAF network element as a basis for selecting the UPF network element. The service capability information of the UPF network element acquired by the NWDAF network element can lay a data foundation for dynamic distribution of the application server, and is favorable for flexibly guiding the flow to different UPF network elements according to the service capability of the UPF network element.

The N3 interface is AN interface between RAN (Radio Access Network) and I-UPF (initial UPF)/UPF, and is mainly used for transmitting uplink and downlink user plane data between 5g (r) AN and UPF. The N6 interface is an interface between DN (Data Network) and UPF, is used for transmitting uplink and downlink user Data streams between UPF and DN, and communicates with DN Network based on IP (Internet Protocol) and routing Protocol.
