AI Technical Summary

Technical Problem

In communication systems that comply with the Third Generation Partnership Program (3GPP) standards, Short Message Services (SMS) cannot change the registered single SMS function and cannot handle the failure and overload of SMS function.

Method used

Receive the network registration request of the terminal through the access and mobility management function (AMF), determine whether multi-radio network access is required, request network repository function (NRF) information about supporting multi-radio network access, and determine based on this information AMF used to perform the network registration process of the terminal.

Benefits of technology

The SMS function changes and troubleshooting are realized, which avoids SMS function overload and ensures the stability and reliability of SMS services.

Abstract

According to an embodiment of the present disclosure, a method performed by an access and mobility management function (AMF) in a wireless communication system may include the steps of: receiving a network registration request message from a terminal; determining whether the terminal needs support for multi-radio network access; if the terminal needs support for multi-radio network access, requesting information about an AMF supporting multi-radio network access from a network repository function (NRF); receiving information about at least one AMF supporting multi-radio network access from the NRF; and determining an AMF for performing a network registration process for the terminal based on the information about the at least one AMF.
