Abstract
A method and apparatus utilizing historical network information for mitigating excessive network updates when performing channel selection between a serving base transceiver station and an adjacent base transceiver station when determined channel selection would result in either a Location Area Update (LAU) or a Routing Area Update (RAU) is presented. If a network update, either LAU or RAU, is the first occurrence, network identification information for the LA or RA is stored and an incremental value indicating occurrence is set; else in the case occurrence is not the first, the incremental value is incremented. A first margin value is then selected if the incremented value does not meet or exceed a predetermined value, or a second margin value is selected if the incremented value does meet or exceed a predetermined value. The signal level of the adjacent base transceiver station is then compared to the reference signal level of the serving base transceiver station plus the selected margin value in order to determine channel selection.
