Retry limits for connection rescue procedures in telecommunication system
First Claim
1. A communications system for enabling communications with one or more mobile stations (MSs) and for limiting rescue attempts of MSs having potentially failing connections, comprising:
- one or more MSs, each MS having a MS processor; and
a network communicatively coupled to the one or more MSs;
wherein the MS processor of the at least one MS having the connection with the network is programmed for detecting when the connection becomes a potentially failing connection, determining current rescue limitations for the potentially failing connection, allowing an attempted rescue of the potentially failing connection if rescue is permitted based on the current rescue limitations, and preventing the attempted rescue of the potentially failing connection if rescue is prohibited based on the current rescue limitations.

Abstract
An efficient and safe procedure to limit the number and concentration of attempts to rescue communication connections from dropping is disclosed. One embodiment limits the number of rescues per connection. Another embodiment allows a rescue only if a certain amount of time has passed since the last rescue. Yet another embodiment limits the total number of rescues per predetermined amount of time. In addition, combinations of these rescue limitations may be employed. In other embodiments, a mobile station (MS) keeps track of the percentage of good frames that were received over some period of time and checks it against a threshold to determine if it is too low to maintain a conversation. Alternatively, if a certain number of number of failed retransmissions of a message requiring acknowledgments are detected, or a certain number of bad frames are detected, or generally a poor connection is detected based on any other indicator, subsequent failures may not be rescued.
