Abstract

A method and system is presented for a mobile wireless communication device that may communicate information to a first network device for enabling authentication, authorization and/or management of accounting for the mobile wireless device for use within a first network that utilizes a first wireless communication standard. A communication session may be established with a second network that utilizes a second wireless standard based on data sent to the second network related to the first authentication, authorization and/or accounting management. The wireless mobile device is operable to establish simultaneous communication sessions with the first network and the second network without communicating authentication, authorization and/or accounting information to the second network. The first and/or second network may comprise and/or share a session control server. The mobile wireless device may receive, store and/or modify additional information associated with the authentication, authorization and/or accounting management.
