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 selectively starting and stopping serving a data capable wireless device from a push server that is registered with a packet data serving node (‘

PDSN’

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

a. receiving status information at the push server via the Internet, the status information indicating whether the data capable wireless device is currently available to receive data; and

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

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

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

4. The method of claim 1, wherein the status information is a data active message.

5. The method of claim 1, wherein the status information is a data inactive message.
