System and method for supporting a keep alive mechanism in a wireless communications system
First Claim
1. A method for communications device operation, the method comprising:
- establishing simultaneous communications sessions in first and second wireless communications networks;
determining if a communications device is within an idle time window, wherein the idle time window is specified by a first time and a second time, and wherein the second time is greater than or equal to the first time;
determining if the communications device is in an idle state in the first wireless communications system;
when an elapsed time since a last transmission by the communications device in the second wireless communications system is less than the first time, not initiating a keep alive procedure in the second wireless communications system;
when the communications device is within the idle time window and when the communications device is in the idle state in the first wireless communications system, initiating the keep alive procedure in the second wireless communications system;
when the communications device is within the idle time window and when the communications device is not in the idle state in the first wireless communications system, not initiating the keep alive procedure in the second wireless communications system; and
when the elapsed time since the last transmission by the communications device in the second communications system is greater than the second time, initiating the keep alive procedure in the second wireless communications system.

Abstract
A system and method for supporting a keep alive mechanism in a wireless communications system are provided. A method for communications device operation includes if the communications device is operating within an idle time window and if the communications device is in the idle state, initiating a keep alive procedure, and if the communications device is not operating within the idle time window and if an elapsed time since a last transmission by the communications device is greater than an upper boundary of the idle time window, initiating the keep alive procedure. The method further includes if the communications device is not operating within the idle time window and if the elapsed time since the last transmission by the communications device is less than a lower boundary of the idle time window, not initiating the keep alive procedure.

8. A method for communications device operation, the method comprising:
-
(a) establishing simultaneous communications sessions in current and alternate wireless communications networks; (b) updating a timer that maintains an elapsed time since a last transmission by a communications device; (c) determining if the communications device is operating in a first priority state; (d) when the communications device is operating in the first priority state and when the communications device is in an idle state in the current wireless communications network, initiating a keep alive procedure in the alternate wireless communications network; (e) when the communications device is operating in the first priority state and when the communications device is not in an idle state in the current wireless communications network, not initiating the keep alive procedure in the alternate wireless communications network; (f) determining if the communications device is operating in a second priority state; and (g) when the communications device is operating in the second priority state, initiating the keep alive procedure in the alternate wireless communications network. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A communications device comprising:
-
a receiver to be coupled to an antenna, the receiver configured to receive signals detected by the antenna; a transmitter to be coupled to the antenna, the transmitter configured to transmit signals using the antenna; a timer configured to measure elapsed time; and a controller coupled to the receiver, to the transmitter, and to the timer, the controller configured to establish simultaneous communications sessions in current and alternate wireless communications networks, and initiate a communications device initiated keep alive procedure in accordance with the elapsed time measured by the timer, wherein the procedure comprises when the elapsed time is less than a first time, not initiate a keep alive procedure in the alternate wireless communications system, when the communications device is greater than the first time and less than a second time, and when the communications device is in the idle state in the current wireless communications system, initiate the keep alive procedure in the alternate wireless communications system, when the communications device is greater than the first time and less than the second time, and when the communications device is not in the idle state in the current wireless communications system, not initiate the keep alive procedure in the alternate wireless communications system, and when the elapsed time greater than the second time, initiate the keep alive procedure in the alternate wireless communications system. - View Dependent Claims (23, 24, 25)
