Abstract
A method and system to help reduce the impact of inter-node latency in session setup. In accordance with the method, a computer will predict a measure of call setup signaling latency for each of a number of wireless communication devices based on actual latency data for the coverage areas in which the devices are positioned, and the computer will then use the predicted latency measures as a basis to select one or more of the devices to wake up in advance of session initiation. The computer will then send at least one message that triggers wakeup of the selected device(s), so as to help reduce latency in subsequent initiation of a session with the selected device(s). Further, the computer may provide notification to a given device of the predicted latencies determined for other devices, to facilitate presentation of the latency information to a user.
