Patent ID: 8249078

Claim:
A method for latency-based management of device-wakeup comprising: determining a source leg latency between at least a call server and a given wireless coverage in which a given wireless communication device (WCD) is positioned; for each of a plurality of WCDs that are buddies of the given WCD, (i) a server determining in which of a plurality of wireless coverage areas the WCD is positioned, (ii) determining a target leg latency between at least the call server and the wireless coverage area in which the WCD is positioned, and (iii) the server predicting a measure of call setup signaling latency for the WCD based at least in part on the determined wireless coverage area in which the WCD is positioned, wherein predicting the measure of call setup signaling latency for the WCD based at least in part on the determined wireless coverage area in which the WCD is positioned comprises predicting the measure of call setup latency by at least summing the determined source leg latency and the determined target leg latency, based on the predicted measures of latencies, the server selecting at least one of the WCDs to wake up, wherein selecting at least one of the WCDs to wake up based on the predicted measures of latencies comprises: for each WCD of the plurality, (a) making a determination of whether the predicted measure of latency is at least a threshold level of latency, and (ii) selecting the WCD to wake up if the determination is that the predicted measure of latency is at least the threshold level of latency, wherein the determination for at least one of the WCDs of the plurality is that the predicted measure of latency is at least the threshold level of latency; and the server sending at least one message to trigger wakeup of the at least one selected WCD.
