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 packet data serving node enabled to communicate wireless device data status information for a wireless device registered with a wireless network, the packet data serving node comprising:

(a) a processor;

(b) a first transceiver interface for communicating with a base station controller and receiving data status information for the wireless device, said data status information indicating if the wireless device can and cannot receive data;

(c) a second transceiver interface for communicating with at least one push server and for transmitting data status information for the wireless device; and

(d) a data storage subsystem, said data storage subsystem including a records storage, said records storage storing data associating a wireless device with at least one push server,

wherein said records storage is accessible by said processor upon receipt by said first transceiver interface of the data status information for the wireless device, enabling the processor to forward the data status information to the at least one push server associated with the wireless device.

2. The packet data serving node of claim 1, wherein the records storage includes:

(a) a device identifier field;

(b) a device status field; and

(c) a server identification field for storing the at least one push server.

3. The packet data serving node of claim 2, wherein the at least one push server in the server identification field registers with the packet data serving node.

4. The packet data serving node of claim 2, wherein the packet data serving node monitors a header of incoming packet data designated for the wireless device to add the at least one push server to the server identification field.

5. The packet data serving node of claim 1, wherein the data status information is received from the wireless device.

6. The packet data serving node of claim 1, wherein the data status information is received from a base station controller.

7. The packet data serving node of claim 6, wherein the data status indication indicates that the wireless device is in a voice call and is incapable of receiving simultaneous voice and data calls.

8. A base station controller adapted to provide data status information to selectively start and stop data transfer between a push server and a wireless device registered with a wireless network, the base station controller comprising:

a) a processor;

b) a first transceiver interface for communicating with a mobile switching center adapted to receive voice call information for the wireless device;

c) a second transceiver interface for communicating with a packet data serving node and adapted to transmit data status information for the wireless device; and

d) a data storage subsystem, the data storage subsystem including a records storage adapted to indicate whether a wireless device can support concurrent voice and data calls and whether the wireless device is in a voice call, wherein the records storage is accessible by the processor upon receipt by the first transceiver interface of voice call information for the wireless device, thereby allowing the processor to forward the data status information to the packet data serving node.

9. The base station controller of claim 8, wherein the records storage includes:

a) a wireless device identifier field;

b) a wireless device capability indicator field;

c) a voice status field; and

d) a data call status field.

10. The base station controller of claim 8, wherein the data status information is one of a data active notification and a data inactive notification.

11. The base station controller of claim 9, wherein the data call status field is adapted to store whether any existing ongoing push services exist.

12. The base station controller of claim 8, wherein the records storage subsystem is updated upon receipt of new voice call information at said first transceiver interface.
