Abstract:
1. A system for user authentication, comprising: a gateway operable to receive a user authentication request associated with a network user in a Remote Authentication Dial-In User Service format of an Internet Protocol from a server, the gateway operable to generate a registry authentication request by converting the Remote Authentication Dial-In User Service format to a Mobile Application Part format of a Signaling System 7 protocol, the gateway operable to communicate the registry authentication request in the Signaling System 7 protocol to a user registry, the gateway further operable to receive a registry authentication response in the Mobile Application Part format of the Signaling System 7 protocol from the user registry, the gateway operable to generate a user authentication response by converting the Mobile Application part format to the Remote Authentication Dial-In User Service format of the Internet Protocol, the gateway operable to communicate the user authentication response in the Internet Protocol to the server, wherein the user authentication response comprises zero or more sets of authentication triplets compatible with a Global System for Mobile Communications network, wherein the gateway is operable to store any received authentication triplets in the registry authentication response in a memory cache for subsequent reuse of authentication triplets, the gateway operable to allow reuse of authentication triplets when the gateway fails to have any fresh authentication triplets and the network user is valid, wherein reuse of authentication triplets is initiated by the server in accordance with a reuse limit indicating a number of times an authentication triplet can be reused.
