Abstract
An SMS or USSD message encapsulating a request for Subscriber Identity Module (SIM) stored data is transported to the mobile station over a connection-less communications link such as a Stand-alone Dedicated Control Channel (SDCCH). An application module within the mobile station having access to the SIM card receives the request signal, retrieves the requesting information from the SIM card, and re-transmits it back to the requesting party. In order to facilitate proper return to the requesting party, if an SMS message is used, a return address is encapsulated into the transmitted SMS message for future reference. The serving mobile switching center (MSC) receives the transmitted message encapsulating the requested subscriber data and routes the received data to the original requesting party.
