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. An apparatus configurable for operation in a wireless device, the apparatus comprising:

processing circuitry including one or more processors communicatively coupled with memory storing instructions that, when executed by the one or more processors, cause the wireless device to;

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

perform an idle mode handoff to a second channel of the network;

receive one or more overhead messages on the second channel of the network;

update one or more network parameters based on information included in the one or more overhead messages received on the second channel of the network; and

send a response message, responsive to the page message received on the first channel, to the network on the second channel.

2. The apparatus of claim 1, wherein the apparatus causes the wireless device to send the response message on the second channel in accordance with an updated state of network parameters based on the one or more overhead messages received on the second channel.

3. The apparatus of claim 1, wherein the idle mode handoff to the second channel comprises an inter-base station or intra-base station handoff to the second channel having better signal quality than the first channel.

4. The apparatus of claim 1, wherein the apparatus causes the wireless device to perform the idle mode handoff to the second channel by at least indirectly transitioning from the first channel to the second channel via one or more intermediate channels of the network.

5. The apparatus of claim 1, wherein:

the apparatus causes the wireless device to perform the idle mode handoff to the second channel by at least performing an access entry handoff (AEHO); and

a pilot signal of the second channel received by the wireless device is stronger than a corresponding pilot signal of the first channel received by the wireless device.

6. The apparatus of claim 1, wherein:

the page message comprises a General Page Message (GPM);

the response message comprises a Page Response Message (PRM); and

the network implements a Code Division Multiple Access (CDMA) radio access technology (RAT).

7. The apparatus of claim 1, wherein the apparatus causes the wireless device to perform the idle mode handoff to the second channel by at least hashing a channel list message received from the network.

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

9. The apparatus of claim 1, wherein the page message comprises a page for a mobile terminating (MT) voice call.

10. A wireless device comprising:

one or more antennas;

a radio configurable to transmit signals to and receive signals from a network via the one or more antennas; and

one or more processors communicatively coupled with memory storing instructions that, when executed by the one or more processors, cause the wireless device to;

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

perform an idle mode handoff to a second channel of the network;

receive one or more overhead messages on the second channel of the network;

update one or more network parameters based on information included in the one or more overhead messages received on the second channel of the network; and

send a response message, responsive to the page message received on the first channel, to the network on the second channel.

11. The wireless device of claim 10, wherein:

the wireless device performs the idle mode handoff to the second channel by at least performing an access entry handoff (AEHO); and

a pilot signal of the second channel received by the wireless device is stronger than a corresponding pilot signal of the first channel received by the wireless device.

12. The wireless device of claim 10, wherein:

the page message comprises a General Page Message (GPM);

the response message comprises a Page Response Message (PRM); and

the network implements a Code Division Multiple Access (CDMA) radio access technology (RAT).

13. The wireless device of claim 10, wherein execution of the instructions causes the wireless device to send the response message on the second channel in accordance with an updated state of network parameters based on the one or more overhead messages received on the second channel.

14. The wireless device of claim 10, wherein the idle mode handoff to the second channel comprises an inter-base station or intra-base station handoff to the second channel having better signal quality than the first channel.

15. The wireless device of claim 10, wherein execution of the instructions causes the wireless device to perform the idle mode handoff to the second channel by at least indirectly transitioning from the first channel to the second channel via one or more intermediate channels of the network.

16. The wireless device of claim 10, wherein execution of the instructions causes the wireless device to perform the idle mode handoff to the second channel by at least hashing a channel list message received from the network.

17. The wireless device of claim 10, wherein the first channel and the second channel are associated with a same System ID/network ID (SID/NID).

18. The wireless device of claim 10, wherein the page message comprises a page for a mobile terminating (MT) voice call.

19. A method for responding to a page message by an apparatus configurable for operation in a wireless device, the method comprising:

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

performing an idle mode handoff to a second channel of the network;

receiving one or more overhead messages on the second channel of the network;

updating one or more network parameters based on information included in the one or more overhead messages received on the second channel of the network; and

sending a response message, responsive to the page message received on the first channel, to the network on the second channel.

20. The method of claim 19, wherein:

the page message comprises a General Page Message (GPM);

the response message comprises a Page Response Message (PRM); and

the network implements a Code Division Multiple Access (CDMA) radio access technology (RAT).
