The circuit switched modem, configured to communicate circuit switched data over a circuit switched network. The packetized data modem, configured to communicate packetized data over a packetized data network. The radio, configured to couple the packetized data modem to the packetized data network via a packetized data radio link, and configured to couple the circuit switched modem to the circuit switched network via a circuit switched radio link, wherein said radio comprise one transmitter and two receivers.

Claims

1. A mobile station comprising:

a radio including a single transmitter, a circuit-switched dedicated receiver, and a packetized-data dedicated receiver,

the single transmitter being configured to either transmit voice calls and circuit-switched data via a CDMA2000 radio link or transmit packetized data via a Long Term Evolution (LTE) radio link,

the circuit switched dedicated receiver being configured to receive voice calls and circuit-switched signals from the CDMA2000 radio link, and

the packetized-data dedicated receiver being configured to receive packetized-data signals from the LTE radio link, the receivers being further configured to receive simultaneously; and

a tune-away controller configured to synchronize time bases of a packetized-data network and a circuit switched network, obtain a circuit-switched notification, and in response to obtaining the circuit-switched notification, end transmission and reception of packetized data via the LTE radio link and the packetized-data network, and start reception of voice calls via the circuit switched dedicated receiver and the circuit switched network.

2. The mobile station of claim 1 further comprising:

a circuit-switched modem configured to transmit CDMA2000 signals over the CDMA2000 radio link via the single transmitter, receive CDMA2000 signals from the CDMA2000 radio link via the circuit switched dedicated receiver, and receive the circuit-switched notification via the CDMA2000 radio link.

3. The mobile station of claim 1 further comprising:

an LTE modem configured to transmit LTE signals over the LTE radio link via the single transmitter, and receive LTE signals from the LTE radio link via the packetized-data dedicated receiver.

4. The mobile station of claim 1, wherein the circuit-switched notification includes a notification of an incoming call to the mobile station.

5. The mobile station of claim 1, wherein the circuit-switched notification includes a notification of an outgoing call from the mobile station.

6. A mobile station comprising:

a radio including a single transmitter, a circuit-switched dedicated receiver, and a packetized-data dedicated receiver,

the single transmitter being configured to transmit voice calls and circuit-switched data via a circuit-switched radio link or transmit packetized data via a packetized-data radio link;

the circuit-switched dedicated receiver being configured to receive voice calls and circuit-switched signals from the circuit-switched radio link; and

the packetized-data dedicated receiver being configured to receive packetized-data signals from the packetized-data radio link;
