AI Technical Summary

Technical Problem

In existing technologies, the first network element fails to confirm whether the second network element has successfully completed authentication with the terminal, which may allow attackers to use the unauthenticated second network element to carry out fraudulent attacks, affecting communication security.

Method used

After receiving the registration request message from the second network element, the first network element determines whether the second network element has successfully completed authentication with the terminal, and decides whether to register the second network element as the terminal's service network element based on the confirmation result. Verification ensures that only network elements that have successfully completed authentication can be registered as service network elements.

Benefits of technology

This effectively prevents fraud attacks, protects communication information security, and ensures that only successfully authenticated network elements can become service network elements for terminals.

Abstract

The present disclosure provides a communication method and apparatus. The method executed by a first network element comprises: the first network element receiving a first message sent by a second network element, wherein the first message is used for requesting registration of the second network element as a service network element of a terminal; and determining whether authentication between the second network element and the terminal is successfully completed. Therefore, the first network element can determine whether authentication between the second network element and the terminal is successfully completed, and further determine, on the basis of a determination result, whether to register the second network element as the service network element of the terminal, so as to avoid directly registering the second network element as the service network element of the terminal, thereby avoiding fraud attacks and ensuring the information security in communication.
