Methods, systems, and computer readable media for providing access network signaling protocol interworking for user authentication
First Claim
1. A method for access network signaling protocol interworking for user authentication, the method comprising:
- in a Diameter signaling router (DSR) including at least one message processor;
receiving, from a node in an access network, a message formatted according to a signaling protocol of the access network and containing an authentication payload formatted according to an authentication protocol, wherein the signaling protocol of the access network comprises a Diameter protocol, the node in the access network comprises a wireless access gateway (WAG), and the message formatted according to the signaling protocol of the access network comprises a Diameter extensible authentication protocol (EAP) request (DER) message;
in response to receiving the DER message, formulating a message formatted according to a signaling protocol of a cellular network, the message including the authentication payload formatted according to the authentication protocol;
forwarding the message formatted according to the signaling protocol of the cellular network to a node in the cellular network that implements the authentication protocol, the message including the authentication payload formatted according to the authentication protocol, wherein the signaling protocol of the cellular network comprises a remote access dial in user service (RADIUS) protocol, the node in the cellular network comprises an authentication, authorization, and accounting (AAA) server, and the message formatted according to the signaling protocol of the cellular network comprises a RADIUS access request message.
