Abstract

A method and system of reachability indication between a wireless device and at least one push server, the method comprising the steps of: sending device status information from the wireless device to the at least one push server; and receiving the status information at the at least one push server; wherein the at least one push server is enabled to selectively start and stop serving the wireless device on the basis of the status information. The method further comprises sending status information to a packet data serving node that stores a list of push servers associated with a wireless device, and having the packet data serving node forward the status information to the push server. The system and method further includes selectively starting and stopping the serving of the wireless device by the push server during a voice call.

Claims

1. A method in a wireless network for communicating a status indication of a wireless device that is registered with a wireless network, the method comprising:

a. receiving status information, the status information indicating whether the wireless device can receive data; and

b. sending the status information to a push server.

2. The method of claim 1, wherein the status information is received from the wireless device.

3. The method of claim 1, wherein the push server is selected from a list of push servers associated with the wireless device.

4. The method of claim 3, wherein the list of push servers is created upon registering the push servers.

5. The method of claim 3, wherein the list of push servers is created by monitoring packet headers of packets sent to the wireless device.

6. The method of claim 3, wherein sending the status information includes retrieving the list of push servers associated with the wireless device.

7. The method of claim 1 wherein the wireless device is unable to support concurrent voice and data calls.

8. The method of claim 7, wherein the status information is received from a base station controller.

9. The method of claim 7, wherein the status information is a data active message.

10. The method of claim 7, wherein the status information is a data inactive message.

11. The method of claim 7, wherein sending the status information includes retrieving the list of push servers associated with the wireless device.

12. A method for communicating a status indication from a wireless device that is registered with a wireless network, the method comprising:

sending status information from the wireless device to a packet data serving node or to a push server with which the wireless device is associated, the status information indicating whether the wireless device can receive data.

13. The method of claim 12, wherein the status information is sent after power-up registration of the wireless device.

14. The method of claim 12, wherein the status information is sent before power-down registration of the wireless device.

15. A method for selectively starting and stopping serving a wireless device from a push server that is registered with a packet data serving node (‘

PDSN’

), the wireless device being registered with a wireless network, the method comprising;

a. receiving status information at the push server, the status information indicating whether the wireless device can receive data; and

b. selectively starting and stopping serving the wireless device at the push server on the basis of the status information.

16. The method of claim 15, wherein the status information is received from the wireless device or the PDSN.

17. The method of claim 15, wherein the wireless device is unable to support concurrent voice and data calls.

18. The method of claim 15, wherein the status information is a data active message.

19. The method of claim 15, wherein the status information is a data inactive message.

20. A method for communicating from a base station controller a status indication of a wireless device that is registered with a wireless network, the wireless device being unable to support concurrent voice and data calls, the method comprising:

a. receiving at the base station controller voice call information at the start and end of a voice call; and

b. sending status information from the base station controller to a packet data serving node.

21. The method of claim 20, wherein if the voice call information indicates the end of the voice call, the status information is a data active message.

22. The method of claim 20, wherein if the voice call information indicates the start of the voice call, the status information is a data inactive message.
