SYSTEM SELECTION IN WIRELESS COMMUNICATIONS NETWORKS

摘要

A method in a hybrid wireless communications device, including comparing a mobility measurement of the wireless communications device to a mobility threshold while connected to a broadband wireless network. In one embodiment, the mobility measure is computed based on signal measurement regression error. The wireless communications device enters a state (612) that monitors a cellular communications network if the mobility measurement is greater than a mobility threshold, and enters a state (614) not monitoring the cellular communications network if the mobility measurement is not greater than the mobility threshold.
