METHOD FOR AUTHENTICATING MULTI BAND MULTI MODE MOBILE COMMUNICATION TERMINAL IN MOBILE COMMUNICATION NETWORK AND MULTI BAND MULTI MODE MOBILE COMMUNICATION TERMINAL THERERFOR

摘要

The present invention is a multi-band multi-mode, multi-band and multi-mode terminal authentication methods for this terminal in a mobile communication network relates to, for receiving a first communication network and a method of authenticating a multi-band multi-mode MS in a communication system including a communication network is the second location registration request message from the first communication network is a multi-band multi-mode terminal, according to the present invention steps; Extracting the subscriber identification information included in the first communication network is the location registration request message; Each step of authenticating the access of the first access network and the second network of the multi-band multi-mode terminal is based on the subscriber identification information of the first communication network; Requesting for IP address assignment of the first communication network is the authentication successful multi-band multi-mode terminal in the second communication network; And transmitting by the multi-band multi-mode terminal for receiving an IP address assigned by the first network is the second communication network; and a ; The present invention is a conventional dual-mode multi-band multi- By integrating the authentication procedure of the terminal and to simplify, and saving resources in the communication system in which waste from the authentication process is in progress to double.
