Abstract

The present invention is a method and system for sending SIP notification messages to a wireless device, for example a wireless telephone, that can accept SIP control messages. A method is described for establishing a data session between a wireless device and a management server over a wireless network, the wireless device operable to receive and parse SIP messages, the wireless network operable to transmit messages between the wireless device and the management server. The method includes retrieving an address for the wireless device on the management server, sending a SIP invite message from the management server to the wireless device, receiving the SIP invite message on the wireless device, parsing the SIP invite message on the wireless device, and establishing the data session between the wireless device and the management server.

Claims

1. A method for establishing a data session between a wireless device and a management server over a wireless network, the wireless device operable to receive and parse SIP messages, the wireless network operable to transmit messages between the wireless device and the management server, the method comprising the steps of:

retrieving an address for the wireless device on the management server;

sending a SIP invite message from the management server to the wireless device;

receiving the SIP invite message on the wireless device;

parsing the SIP invite message on the wireless device and;

establishing the data session between the wireless device and the management server.

2. The method of claim 1, where the SIP invite message contains bootstrap information for the wireless device to connect to the management server.

3. The method of claim 2, where the bootstrap information contained in the SIP invite message includes server security credentials and a server address to which to connect to the management server.

4. The method of claim 1, further comprising the step of:

receiving notification messages sent by the management server as SIP invite messages on a specific port on the wireless device.

5. The method of claim 1, further comprising the step of:

registering a device identity and network address of the wireless device with the management server.

6. The method of claim 1, further comprising the step of:

determining the network address of the wireless device from a device identity.

7. The method of claim 6, wherein the step of determining the network address of the wireless device comprises the steps of:

sending the device identity from the management server to a database using a SIP message and;

sending the network address of the device to the management server from the database using a SIP message.

8. The method of claim 1, further comprising the step of:

re-registering the wireless device, with the management server when a network address of the wireless device changes.

9. A method for establishing a data session between a wireless device, a proxy device and a management server over a wireless network, the wireless device and the proxy device operable to receive and parse SIP messages, the wireless network operable to transmit messages between the wireless device and the proxy device and the proxy device and the management server, the method comprising the steps of:

registering the wireless device with the proxy device;

sending a notification message embedded inside a SIP invite message from the management server to the proxy device;

sending the SIP invite message from the proxy device to the wireless device;

receiving the SIP invite message on the wireless device; and

parsing the SIP invite message on the wireless device.

10. The method of claim 9, where a device identity of the wireless device is encapsulated within the SIP message sent to the proxy device.

11. The method of claim 9, where the notification message embedded in the SIP invite message contains bootstrap information for the device to connect to the management server.

12. The method of claim 11, where the bootstrap information contained in the SIP invite message includes server credentials and a server address to which to connect to the management server.

13. The method of claim 9, further comprising the step of:

receiving the notification messages sent as SIP invite messages on a specific SIP port on the wireless device.

14. The method of claim 9, further comprising the step of:

registering a network address of the proxy device with the management server.

15. The method of claim 9, further comprising the step of:

registering a device identity and network address of the wireless device with the proxy device.

16. The method of claim 9, where the proxy device registers a network address of the wireless device with the management server.

17. The method of claim 9, where a link local address of the wireless device is encapsulated within the SIP message sent to the proxy device.

18. The method of claim 9, where the proxy device is listening on a special port for notification messages sent as SIP invite messages.

19. The method of claim 9, where the proxy registers its network address with the management server.

20. The method of claim 9, where the wireless device registers its device identity and link local address with the proxy device.

21. The method of claim 9, where the proxy registers the link local address of the wireless device with the management server.

22. The method of claim 9, further comprising the step of:

re-registering the proxy device with the management server when a network address of the proxy device changes.

23. The method of claim 9, further comprising the step of:

detecting a change of a network address of the wireless device;

re-registering the wireless device with the proxy device; and

sending the re-registration of the wireless device to the management server from the proxy device.

24. The method of claim 9, where the proxy device on a change in a network address of the registered wireless device, re-registers the network address of the wireless device with the management server.
