A AUTHENTICATION METHOD FOR USERS OF CODE DIVISION MULTIPLE ACCESS SYSTEM ROAMING TO GLOBAL MOBILE COMMUNICATION SYSTEM

摘要

The present invention disclose a authentication method for users of code division multiple access (CDMA) system roaming to global mobile communication (GSM) system, when develop a new service for users to roaming to global mobile communication system, proceed adaptation though a certain algorithm, convert CDMA authentication parameter and GSM authentication parameter each other, use GSM authentication flow to carry CDMA authentication parameter, and use inhered UIM card of CDMA user to authenticate, avoid the runner providing new user identification module to CDMA users, at the same time, it doesn't need to amend existing CDMA network device and GSM network device, realize simplification and boost up runnable system of service.
