Method of implementing authentication of high-rate packet data services

摘要

Disclosed is a method for implementing authentication of high rate packet data (HRPD) services, applicable to multi-mode networks including IS95/CDMA2000 1x and CDMA2000 HRPD networks. The method includes an Access Terminal (AT) using the user information in the User Identity Module (UIM) as the user identifier and starting an authentication in accordance with the Extended Authentication Protocol (EAP). A Mobile Switching Center (MSC)/Visiting Location Register (VLR) obtains a random number and a first authentication number based on the user identifier, and the AT calculates a second authentication number based on said random number. The MSC/VLR compares the first authentication number with the second authentication number to determine whether they are consistent. If consistent, the authentication is successful. Otherwise, the authentication is aborted. With the disclosed method, authentication can be made by using the original MSC and HLR/AC in the CDMA IS95 or CDMA2000 1x network. The method allows low cost and easy operation for the user as well as convenient maintenance for the operator.
