Abstract:
1. A method for implementing authentication of high-rate packet data (HRPD) services, the method comprising the steps of: (A) taking, by way of an Access Terminal (AT), user information in a User Identity Module (UIM) as a user identifier and starting an authentication of extended authentication protocol (EAP); (B) obtaining, by way of a Mobile Switching Center/Visiting Location Register (MSC/VLR), a random number and a first authentication number corresponding to the random number based on the user identifier, wherein said first authentication number is calculated with Shared Secret Data (SSD) stored at a network side and said random number; and, (C) calculating, by way of the AT, a second authentication number based on said random number and SSD stored in AT, judging, by way of the MSC/VLR, by comparing whether the first authentication number and the second authentication number are consistent, such that, if yes, the authentication succeeds, and otherwise, the authentication fails.
