Abstract:
1. A method for wirelessly transmitting and receiving packet switched traffic and circuit switched traffic in an electronic device that has first and second baseband processor integrated circuits, comprising: transmitting and receiving the packet switched traffic using the first baseband processor integrated circuit; transmitting and receiving the circuit switched traffic using the second baseband processor integrated circuit, wherein the first baseband processor integrated circuit is coupled to the second baseband processor integrated circuit via an inter-processor communications path; with a universal integrated circuit card connected to the first baseband processor integrated circuit, providing subscriber identity module (SIM) profile data to the first baseband processor integrated circuit; and conveying control signals that include the SIM profile data from the first baseband processor integrated circuit to the second baseband processor integrated circuit via the inter-processor communications path to enable the second baseband processor integrated circuit to register with a wireless network.
