Abstract

A method for responding to a page message is provided. The method can include a wireless communication device receiving a page message on a first channel of a first network; suspending a connection to a second network in response to receiving the page message; transitioning to a second channel of the first network prior to responding to the page message; and sending a response message responsive to the page message on the second channel.

Claims

1. A method for responding to a page message, the method comprising a wireless communication device:

receiving a General Page Message (GPM) on a first channel of a Code Division Multiple Access 2000 (CDMA2000) 1X network;

suspending a connection to a second network in response to receiving the GPM, the second network implementing a Long Term Evolution (LTE) radio access technology (RAT);

transitioning to a second channel of the CDMA2000 1X network prior to responding to the GPM; and

sending a Page Response Message (PRM) responsive to the GPM on the second channel.

2. The method of claim 1, wherein suspending the connection to the second network comprises the wireless communication device:

tuning away from the CDMA2000 1X network to the second network;

sending an Extended Service Request (ESR) to the second network; and

returning to the CDMA2000 1X network.

3. The method of claim 1, wherein the wireless communication device uses a single radio to support both communication via the CDMA2000 1X network and communication via the second network.

4. The method of claim 1, wherein transitioning to the second channel comprises the wireless communication device performing an idle mode handoff.

5. The method of claim 1, wherein transitioning to the second channel comprises the wireless communication device performing channel hashing to the second channel based at least in part on a channel list message received from the CDMA2000 1X network.

6. The method of claim 1, wherein transitioning to the second channel comprises the wireless communication device indirectly transitioning from the first channel to the second channel via one or more intermediate channels of the CDMA2000 1X network.

7. The method of claim 1, wherein the first channel and the second channel are associated with a same System ID/network ID (SID/NID).

8. The method of claim 1, wherein the GPM comprises a page for a mobile terminating (MT) voice call.

9. A wireless communication device comprising:

a radio configured to support communication with a first network and with a second network; and

processing circuitry coupled to the radio, the processing circuitry configured to control the wireless communication device to at least;

receive a page message on a first channel of the first network;

suspend a connection to the second network in response to receiving the page message;

transition to a second channel of the first network prior to responding to the page message; and

send a response message responsive to the page message on the second channel.

10. The wireless communication device of claim 9, wherein the processing circuitry is configured to control the wireless communication device to suspend the connection to the second network at least in part by controlling the wireless communication device to:

tune the radio away from the first network to the second network;

send a message configured to trigger suspension of the connection to the second network to the second network; and

tune the radio back to the first network.

11. The wireless communication device of claim 9, wherein the processing circuitry is configured to control the wireless communication device to transition to the second channel at least in part by controlling the wireless communication device to perform an idle mode handoff.

12. The wireless communication device of claim 9, wherein the processing circuitry is configured to control the wireless communication device to transition to the second channel at least in part by controlling the wireless communication device to perform channel hashing to the second channel.

13. The wireless communication device of claim 9, wherein the processing circuitry is configured to control the wireless communication device to transition to the second channel at least in part by controlling the wireless communication device to indirectly transition from the first channel to the second channel via one or more intermediate channels of the first network.

14. The wireless communication device of claim 9, wherein the first network is a legacy network having a circuit switched (CS) domain configured to support CS services, and wherein the second network does not have a CS domain.

15. The wireless communication device of claim 14, wherein the first network is a Code Division Multiple Access 2000 (CDMA2000) 1x network, and wherein the second network implements a Long Term Evolution (LTE) radio access technology (RAT).

16. The wireless communication device of claim 15, wherein the page message is a General Page Message (GPM), and wherein the response message is a Page Response Message (PRM).

17. The wireless communication device of claim 14, wherein the page message comprises a page for a mobile terminating (MT) voice call.

18. A computer program product for responding to a page message, the computer program product comprising at least one non-transitory computer readable storage medium having computer program code stored thereon, the computer program code comprising:

program code for receiving a page message on a first channel of a first network;

program code for suspending a connection to a second network in response to receiving the page message;

program code for transitioning to a second channel of the first network prior to responding to the page message; and

program code for sending a response message responsive to the page message on the second channel.

19. The computer program product of claim 18, wherein the program code for transitioning to the second channel comprises program code for performing an idle mode handoff.

20. The computer program product of claim 18, wherein the program code for transitioning to the second channel comprises program code for performing channel hashing to the second channel.
