1. A method for access network protocol interworking and authentication proxying comprising:

  • in a Diameter signaling router (DSR) including at least one processor;

    receiving, on a first interface of the DSR that supports extensible authentication protocol (EAP), a message requesting authentication from a node in an access network, wherein receiving the message requesting authentication information includes receiving a Diameter SWa, STa, or SWm message requesting authentication information and including an EAP payload;

    terminating the EAP on the first interface;

    using a native protocol of a cellular network to obtain authentication challenge information from the cellular network, wherein using a native protocol to obtain authentication challenge information from the cellular network includes formulating and transmitting, on a second interface of the DSR that does not support the EAP, a Diameter S6a or SWx message to obtain the authentication challenge information;

    communicating the authentication challenge information to the node in the access network, wherein communicating the authentication challenge information to the node in the access network includes using the Diameter protocol;

    receiving an authentication response from the node in the access network;

    determining whether the authentication response matches an expected response; and

    in response to determining that the authentication response matches an expected response, sending a message to the node in the access network indicating successful authentication.
