Abstract:
1. A method for distributing authentication in Internet Protocol Multimedia Subsystem and other Session Initiation Protocol systems, the method comprising the steps of: loading a local database copy of user profiles in an edge element in a network from a remotely located master user database, wherein the edge element provides network access, and wherein the local database copy of the user profiles comprises one of a full copy of all user profiles known in a control entity and a partial copy of only user profiles known to access the edge element; pre-authenticating Session Initiation Protocol requests by service requestors utilizing the local database copy of the user profiles at the edge element without involvement of the remotely located master user database, wherein the pre-authenticating comprises partial or full authentication of the Session Initiation Protocol requests, and wherein the pre-authenticating is performed by the edge element concurrently while the edge element provides the network access to the service requestors; and providing services to the service requestors responsive to the Session Initiation Protocol requests; wherein the edge element is configured to cache network resources comprising content and software responsive to the Session Initiation Protocol requests in a predictive manner.
