AI Technical Summary

Technical Problem

In existing technologies, when a terminal switches networks, it needs to perform multiple air interface interactions with the core network elements of the new network, resulting in a serious waste of network air interface resources and reduced service interaction efficiency.

Method used

By obtaining the terminal's subscription information and interface information through the source core network elements of the source network, the mobile identity information elements are dynamically adjusted, the mobility management process is optimized, and the terminal is ensured to select the appropriate registration method between different networks, thereby reducing unnecessary signaling interactions.

Benefits of technology

It improves the flexibility and adaptability of the network architecture, reduces connection failure rate, saves network resources, and enhances user experience and network efficiency.

Abstract

The application discloses a terminal access management method and a communication system. The method comprises the following steps: a source core network element of a source network receives a first registration request message sent by a terminal, and the first registration request message carries at least a first identity of the terminal; subscription information of the terminal is obtained according to the first identity; interface information is obtained, wherein the interface information is used to reflect whether there is a network interface between the source core network element and a target core network element of a target network; and a target registration acceptance message is sent to the terminal based on the subscription information and the interface information, wherein the target registration acceptance message at least comprises a mobile identity information element, which is used to indicate the type of a second identity carried in a second registration request message sent by the terminal when the terminal accesses the target network. The application solves the technical problem that network air interface resources are seriously wasted due to the fact that the existing terminal needs to perform multiple air interface interactions with the core network element of the newly accessed network when switching the network.
