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 for data reachability indication between a wireless device registered with a wireless network and at least one push server, the method comprising the steps of:

(a) sending device data status information from the wireless device to the at least one push server, said data status information indicating if the wireless device can and cannot receive data;

(b) receiving the data status information at the at least one push server; and

(c) the at least one push server selectively starting and stopping serving the wireless device on the basis of the data status information.

2. The method of claim 1, wherein the data status information is sent after power tip registration of the wireless device.

3. The method of claim 1, wherein the data status information is sent before power down deregistration of the wireless device.

4. A method for data reachability indication between a wireless device registered with a wireless network and at least one push server, the method comprising the steps of:

(a) sending device data status information from the wireless device to a packet data serving node, said data status information indicating if the wireless device can and cannot receive data;

(b) receiving the data status information at the packet data serving node and sending from the packet data serving node a data status message to the at least one push server, the data status message corresponding to the data status information;

(c) receiving the status message at the at least one push server; and

(d) the at least one push server selectively starting and stopping serving the wireless device on the basis of the data status information.

5. The method of claim 4, wherein the packet data serving node stores a list of push servers associated with the wireless device.

6. The method of claim 5, wherein the list of push servers is created by having the push servers to register with the packet data serving node.

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

8. The method of claim 5, wherein the step of sending the data status message includes retrieving the list of push servers associated with the wireless data device.

9. A method of reachability indication between a wireless device and at least one push server, the wireless device being unable to support concurrent voice and data calls, the method comprising the steps of:

(a) sending voice call information at the start and end of a voice call from a mobile switching center to a base station controller;

(b) sending from the base station controller to a packet data serving node a data status notification;

(c) receiving the data status notification at the packet data serving node and sending to the at least one push server status information; and

(d) 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.

10. The method of claim 9, wherein if the voice call information indicates the start of a voice call, the data status notification is a data inactive notification.

11. The method of claim 9, wherein if the voice call information indicates the end of a voice call, the data status notification is a data active notification.

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

13. The method of claim 11, wherein the status information is a data active message.

14. The method of claim 9, wherein the packet data serving node stores a list of push servers associated with the wireless device.

15. The method of claim 14, wherein the list of push servers is created by having the push servers to register with the packet data serving node.

16. The method of claim 14, wherein the list of push servers is created by monitoring packet headers of packets sent to the wireless device.

17. The method of claim 9 wherein the step of sending the status information includes retrieving the list of push servers associated with the wireless data device.

18. A push server enabled to selectively start and stop serving a wireless device registered with a wireless network on the basis of received data status information, said data status information indicating if the wireless device can and cannot receive data, said push server comprising:

(a) a transceiver enabled to receive data status information about the wireless device;

(b) a processor enabled to interpret data status information about the wireless device and to start or stop serving the wireless device based on the data status information; and

(c) a storage subsystem capable of storing the data status information for the wireless device.

19. A wireless data device registered with a wireless network the wireless data device comprising:

(a) a processor;

(b) a user interface communicating with the processor for providing input to the wireless data device;

(c) a transceiver interface controlled by said processor for communicating with a wireless network; and

(d) a storage subsystem communicating with said processor and having information about push servers serving said wireless data device, wherein said wireless data device communicates data status information to the push servers serving the wireless data device using said transceiver interface over said wireless network, said data status information indicating if the wireless device can and cannot receive data.

20. The wireless data device of claim 19, wherein the data status information is conveyed after power tip of the wireless data device.

21. The wireless data device of claim 19, wherein the data status information is conveyed before power down of the wireless data device.
