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.
