Abstract
A mobile station for notification of a circuit switched event. The mobile station includes a circuit switched modem, a packetized data modem, a radio, and a tune away controller. The circuit switched communicates circuit switched data over a circuit switched network. The packetized data modem communicates packetized data over a packetized data network. The radio couples the packetized data modem to the packetized data network via a packetized data radio link, and couples the circuit switched modem to the circuit switched network via a circuit switched radio link. Only one of the links may be active at a time. The tune away controller is coupled to the circuit switched modem and to the packetized data modem, and indicates tune away events over the packetized data network so that the circuit switched event is processed by the mobile station. The tune away controller directs switching between the links.
