Method and apparatus for using historical information network to mitigate excessive network updates when a communication channel is selected.

摘要

A method of selecting a communication channel for communications with a base transceiver station service or a base transceiver station adjacent, wherein a communications device (10) receives identification information network, comprising information identifying areas network, a signal having a signal level of the base transceiver station adjacent, and a reference signal having a signal level reference base transceiver station service, the method being characterized to select the communication channel by the steps of: storing identification information from the network if channel selection between two areas results in a network area update; set a value if the update area network has not previously occurred; increase the value if the update area network previously occurred between the same two areas (14); comparing the signal level with the reference signal level plus a margin value if the incremented value is greater or equal to the predetermined value; and select a communications channel with the adjacent base transceiver station if the signal level meets or exceeds the level of the reference signal plus a margin value (18).
