Patent ID: 8213990

Claim:
A system for providing remote subscriber identity cards to a mobile station, wherein the remote subscriber identity cards comprises a first subscriber identity card and a second subscriber identity card, comprising: a Bluetooth module establishing a Bluetooth connection to the mobile station; a controller accessing the first and second subscriber identity cards to obtain identity information and providing the obtained information to the mobile station via the Bluetooth connection such that the mobile station camps on a first cell according to the obtained information corresponding to the first subscriber identity card and a second cell according to the obtained information corresponding to the second subscriber identity card; a selecting circuit selectively coupling the controller to the first subscriber identity card or the second subscriber identity card so as to access the coupled subscriber identity card; a first switch enabling or disenabling the first subscriber identity card; and a second switch enabling or disenabling the second subscriber identity card, wherein the controller initiates a first operating voltage for the first subscriber identity card when the first switch is switched on, and the controller initiates a second operating voltage for the second subscriber identity card when the second switch is switched on, wherein the selecting circuit further transfers clock and reset signals from the controller to the coupled subscriber identity card and transfers data signal between the controller and the coupled subscriber identity card, wherein when the first or second subscriber identity card is enabled, the controller sends a card reset requirement with a specific card ID corresponding to the enabled subscriber identity card, to the mobile station via the Bluetooth connection, and in response to the card reset requirement, the mobile station sends a Answer To Reset (ATR) requirement with the specific card ID, to the controller via the Bluetooth connection.
