Method and apparatus for reducing call setup delay
First Claim
1. A method for reducing delays in setting up a new call to a power-saving enabled subscriber device by detecting a trigger event indicating future data communications are more likely to occur, the method comprising:
- the subscriber device operating in a low-power state in which at least one wireless link is disconnected from a wireless data network and in which the wireless link is periodically temporarily re-established to check for pending transmissions at a first reduced frequency before re-entering the disconnected state in response to finding no pending data transmissions; and
responsive to the subscriber device detecting a trigger event indicating future data communications are more likely to occur, the trigger event being one selected from;
(i) the subscriber device detecting that the subscriber device has entered or exited a particular incident site as defined in a geo-fence and associated with an incident occurrence, (ii) the subscriber device detected that it has been instructed to proceed to a particular geographic incident location defined at the subscriber device and associated with an incident occurrence, (iii) the subscriber device detecting a new association, or change in existing association, of the subscriber device with a particular role at a particular geographic region associated with an incident occurrence, and (iv) the subscriber device detecting a new association, or change in existing association, of the subscriber device with a particular talk group, the subscriber device transitioning the subscriber device to a higher-power state and the subscriber device transmitting data messages over the wireless link at a second increased frequency to cause the subscriber device to remain in a connected state more often compared to the low-power state.

Abstract
A power-saving enabled subscriber device operates in a low-power state in which at least one wireless link is disconnected from a wireless data network and in which the wireless link is periodically temporarily re-established to check for pending transmissions at a first reduced frequency before re-entering the disconnected state in response to finding no pending data transmissions. To reduce delays in setting up a new call to the subscriber device, and responsive to detecting an association, or change in association, of the subscriber device with one of (i) a particular geographic region, (ii) a particular role at a particular geographic region, and (iii) a particular talk group, the subscriber device transitioning the subscriber device to a higher-power state and transmitting data messages over the wireless link at a second increased frequency to cause the subscriber device to remain in a connected state more often compared to the low-power state.

15. A power-saving enabled subscriber device operating in a wireless communications network and capable reducing delays in setting up a new call by detecting a trigger event indicating future data communications are more likely to occur, the subscriber device comprising:
-
a memory; a transceiver; and a processor configured to; cause the subscriber device to operate in a low-power state in which at least one wireless link is disconnected from a wireless data network, via the transceiver, and in which the wireless link is periodically temporarily re-established, via the transceiver, to check for pending transmissions at a first reduced frequency before re-entering the disconnected state in response to finding no pending data transmissions; and in response to detecting a trigger event indicating future data communications are more likely to occur, the trigger event being one selected from;
(i) detecting that the subscriber device has entered or exited a particular incident site as defined in a geo-fence and associated with an incident occurrence, (ii) the subscriber device detected that it has been instructed to proceed to a particular geographic incident location defined at the subscriber device and associated with an incident occurrence, (iii) detecting a new association, or change in existing association, of the subscriber device with a particular role at a particular geographic region associated with an incident occurrence, and (iv) detecting a new association, or change in existing association, of the subscriber device with a particular talk group, cause the subscriber device to transition to a higher-power state and to transmit data messages, via the transceiver, over the wireless link at a second increased frequency to cause the subscriber device to remain in a connected state more often compared to the low-power state. - View Dependent Claims (16, 17, 18, 19, 20)
