Abstract
An improved method and system for terminating dormant mode wireless packet data sessions when a remote network node becomes inaccessible. A wireless subscriber station sends the wireless network a termination notification identifying a packet data session corresponding to a remote network node that has become inaccessible and should be terminated.

1. A method for processing a land-to-mobile packet data call origination comprising the steps of:
-
receiving a page from a wireless network to originate a packet data call with an inaccessible remote network node having a dormant network connection with a packet data network; and
sending a release message to the wireless network, said release message comprising a packet data session termination notification. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16)
performing service negotiation with the wireless network; and
extracting packet data session identification information associated with the land-to-mobile packet data call origination from information received during said service negotiation, wherein the packet data session identified corresponds to the inaccessible remote network node.
-
-
4. The method of claim 3 wherein said release message is a release request message having an order qualification code (ORDQ) field identifying the packet data session corresponding to the inaccessible remote network node.
-
5. The method of claim 4 wherein said ORDQ field comprises a bit map identifying the packet data session corresponding to the inaccessible remote network node.
-
6. The method of claim 3 wherein said release message is a Resource Release Request message identifying the packet data session corresponding to the inaccessible remote network node.
-
7. The method of claim 6 wherein said release message comprises a service reference identifier based on the packet data session corresponding to the inaccessible remote network node.
-
8. The method of claim 3 further comprising the step of storing a session identifier in the packet data session termination notification identifying the packet data session corresponding to the inaccessible remote network node.
-
9. The method of claim 8 wherein said session identifier is a service reference identifier.
-
10. The method of claim 3 further comprising the step of sending a connect order message to the wireless network.
-
11. The method of claim 1 further comprising the steps of:
-
performing service negotiation with the wireless network; and
using information received during said service negotiation to identify the land-to-mobile call origination as a packet data call origination.
-
-
12. The method of claim 11 wherein said release message is a release request message having an order qualification code (ORDQ) field specifying one or more packet data sessions to be terminated.
-
13. The method of claim 12 wherein said ORDQ field comprises a bit map that identifies said one or more packet data sessions to be terminated.
-
14. The method of claim 11 wherein said release message is a release request message having an order qualification code (ORDQ) field specifying that all packet data sessions be terminated.
-
15. The method of claim 11 wherein said release message is a Resource Release Request message identifying one or more packet data sessions to be terminated.
-
16. The method of claim 15 wherein said release message comprises a service reference identifier corresponding to each of said one or more packet data sessions to be terminated.
-
17. A method for processing a land-to-mobile packet data call origination comprising the steps of:
-
receiving a page from a wireless network to originate a packet data call;
performing service negotiation with the wireless network;
extracting packet data session identification information associated with the land-to-mobile packet data call origination from information received during said service negotiation, wherein the packet data session identified corresponds to an inaccessible remote network node;
receiving and decoding an alert with information message directing the activation of a ringer;
sending a connect order message to the wireless network without activating the ringer; and
sending a release message to the wireless network, said release message comprising a packet data session termination notification.

-
18. Wireless subscriber station apparatus comprising;
-
a control processor configured to receive a page from a wireless network to originate a packet data call with an inaccessible remote network node having a dormant network connection with a packet data network, and generating a release message comprising a packet data session termination notification; and
a wireless network communication module configured to transmit the release message to the wireless network. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
-
-
26. A method of packet data call origination comprising:
-
receiving a page from a wireless network to originate a packet data call for a remote network node having a dormant connection through the wireless network to a packet data network;
evaluating the accessibility of the remote network node; and
sending a release message to the wireless network in response to the page if the remote network node is inaccessible. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 40, 41)
performing service negotiation with the wireless network in response to the page; and
extracting information from the service negotiation identifying a packet data session for the remote network node.
-
-
29. The method of claim 28 wherein the release message comprises a release request message having an order qualification code (ORDQ) field identifying the packet data session.
-
30. The method of claim 29 wherein the ORDQ field comprises a bit map identifying the packet data session.
-
31. The method of claim 28 wherein the release message comprises a Resource Release Request message identifying the packet data session.
-
32. The method of claim 31 wherein the release message further comprises a service reference identifier based on the packet data session.
-
33. The method of claim 28 further comprising sending a connect order message to the wireless network.
-
34. The method of claim 28 further comprising:
-
receiving an alert from the wireless network directing the activation of a ringer; and
sending a connect order message to the wireless network without activating the ringer.
-
-
40. The subscriber station of claim 32 wherein the release message comprises a Resource Release Request message identifying the packet data session.
-
41. The subscriber station of claim 40 wherein the release message further comprises a service reference identifier based on the packet data session.
-
