Data information acquisition method and device, related equipment and medium

Abstract

The embodiment of the invention provides a data information acquisition method and device, related equipment and a medium. The method comprises the following steps: acquiring a capability calling subscription request sent by a second functional network element based on subscription request parameter information, wherein the signing request parameter information is determined by authentication response parameter information, the authentication response parameter information is obtained by performing authentication processing on the capability calling request by the network open function equipment, and the capability calling request is sent by the second function network element based on the first subscription rule; acquiring access parameter information from the signing request parameter information, and performing signing verification on the capability calling signing request based on the access parameter information; generating capability calling contract signing response informationfor the capability calling contract signing request when contract signing verification succeeds, and returning the capability calling contract signing response information to the second function network element, wherein the capability calling subscription response information is used for indicating the second functional network element to access the first functional network element. By adopting the method and the device, the data information acquisition efficiency can be improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to the technical field of 5G (5th Generation mobile network, fifth generation mobile communication technology), and in particular to a data information acquisition method, device, related equipment and media. Background technique [0002] In the core network of the 5G system, there is a network exposure function device that can collect, analyze, and reorganize network capabilities. The network exposure function device can be a network capability exposure function that can support one or more functions (Network Exposure Function, NEF) entity. Among them, it is understandable that each network element of the 5G core network and external network elements need to notify the NEF entity of its network service capabilities, so that each network element can learn the business of the network element it is interested in through the NEF entity capability information. This means...

Problems solved by technology

This means that in the existing 5G system, it is difficult to directly perform data interaction between the network elements in the external network and the network elements in the internal network (that is, the 5G core network), that is, the external network needs to be provided indirectly through the NEF entity. Information conversion and exchange between the internal network (5G core network), thereby reducing the efficiency of obtaining information between these network elements
