Title:
METHOD AND APPARATUS FOR REMOTE MULTIPLE ACCESS TO SUBSCRIBER IDENTITY MODULE
Document Type and Number:
WIPO Patent Application WO2002019664
Kind Code:
A3
Abstract:
An apparatus enabling multiple client devices (204, 206 and 208) to access a SIM card (202), coupled to a server device (200), along a local link (210), that includes a SIM card interface (214) and a router unit (226). The SIM card interface (214) couples the SIM card (202) to the server device (200), formats the commands from the client devices for transmission to the SIM card, and formats responses to the commands for transmission from the SIM card to the client devices. The router unit (226) routes the commands from the server device to the SIM card interface, and routes the responses to the commands for transmission along the local link from the SIM card to the client devices. A broadcast message is transmitted by the router unit along the local link to the client devices in response to detecting a physical presence signal transmitted by the SIM card interface in response to the SIM card being coupled to the SIM card interface.
