Problems solved by technology

[0004] However, with the network reconfiguration of the fifth generation mobile communication technology (5G, 5-Generation), the core network functional entity, signaling interface and signaling protocol will change accordingly, such as figure 2 The schematic diagram of the 5G network architecture is shown; at the same time, different network slices will appear in the 5G network, and there will be a need for logical isolation, maintaining a large static connection with signaling nodes, and performing hop-by-hop relay or multi-level transfer signaling for signaling The network transfer method will make the signaling connection more complicated and the efficiency of signaling interaction will be reduced, which is no longer applicable to the 5G core network architecture

Abstract

The invention discloses a session implementing method. The method comprises the steps that: the core network element acquires first information and second information of a destination node on the basis of first key information, wherein the first information is different from the second information, and the first key information at least comprises routing keywords; and on the basis of the first information and the second information, a signaling request message of a user is sent to the destination node. The invention simultaneously further discloses a core network element.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a session realization method and a core network element. Background technique [0002] like figure 1 As shown, in the 2 / 3 / 4G era, the signaling network, as the neural network of the core network, is mainly responsible for switching signaling between core network elements, user data entities, and service platforms, and provides important support for the basic services of the core network . [0003] In order to simplify the signaling connection and data configuration, there is no direct routing and direct signaling connection between the core network elements of the entire network and the user database, service platform or service policy control platform, and inter-provincial signaling needs to go through multiple signaling transfers Points are translated and relayed, and finally delivered to the destination node. [0004] However, with the reconfiguration of the f...
