Managing wireless packet service resources
First Claim
1. In a packet switching network, a method of releasing long-term dormant calls comprising the steps of:
- detecting, in said packet switching network, packet switched data (PSD) calls for which no packets have been transmitted for a predetermined period of time;
sending an alerting message to a mobile station connected on one of said calls;
responsive to a request to release said call, releasing said call;
responsive to absence of a response from said mobile station, releasing said call,prior to performing said detecting step, determining whether a shortage of resources exists in a switch serving said long-term dormant calls; and
if it is determined that a shortage of resources exist, performing said detecting.

Abstract
In a packet switch for communicating packet switched data to and from a plurality of wireless mobile stations, a method and apparatus for automatically releasing resources tied up for communicating with dormant mobile stations. If the station has been dormant for a sufficiently long time, an alerting message is sent to the user of that mobile station. The user can then respond by requesting a release of the packet switched data (PSD) call currently connected to that mobile station or can request that the connection remain up. Advantageously, if the user of the station does not respond, then following a timeout the PSD call is released and the resources required for keeping the dormant call in existence are made available for new calls.

5. In a packet switching network, a method of releasing long-term dormant calls comprising the steps of:
-
detecting, in said packet switching network, packet switched data (PSD) calls for which no packets have been transmitted for a predetermined period of time; sending an alerting message to a mobile station connected on one of said calls; responsive to a request to release said call, releasing said call; responsive to absence of a response from said mobile station, releasing said call, wherein the step of releasing said call responsive to absence of a response from said mobile station comprises the step of; timing for another predetermined period of time to see if a response is received from said mobile station; and if no response is received from said mobile station within said another predetermined period of time, releasing said call.

6. In a packet switching network, apparatus for releasing long-term dormant calls, comprising:
-
means, in said packet switching network, for detecting packet switched data (PSD) calls for which no packets have been transmitted for a predetermined period of time; means for sending an alerting message to a mobile station connected on one of said calls; means, responsive to a request to release said call, for releasing said call; means, responsive to absence of a response from said mobile station, for releasing said call, further comprising; means for determining whether a shortage of resources exists in a switch serving said long-term dormant calls; and if it is determined that a shortage of resources exist, means for initiating performance of the detecting step, and a resulting sending step and releasing steps. - View Dependent Claims (7, 8, 9)

10. In a packet switching network, apparatus for releasing long-term dormant calls, comprising:
-
means, in said packet switching network, for detecting packet switched data (PSD) calls for which no packets have been transmitted for a predetermined period of time; means for sending an alerting message to a mobile station connected on one of said calls; means, responsive to a request to release said call, for releasing said call; means, responsive to absence of a response from said mobile station, for releasing said call, wherein the means for releasing said call responsive to absence of a response from said mobile station comprises; means for timing for another predetermined period of time to see if a response is received from said mobile station; and if no response is received from said mobile station within said another predetermined period of time, means for releasing said call.
