Abstract

A method for prioritized searching of pilot signals of neighboring base stations in a CDMA communication system, in which the frequency of revisitation of a high priority neighbor's pilot is increased with respect to the lower priority neighboring pilots. The mobile station receives a neighbor list message (200) from the base station. The neighbor list message includes pilot signal parameters for a plurality of neighboring pilot signals transmitted by neighboring base stations. A plurality of priority indications, each corresponding to one of the plurality of pilot signals is also included. In a preferred embodiment, the first of the plurality of priority indications corresponds to a high priority and the second of the plurality of priority indications corresponds to a low priority. The mobile station stores these pilot signal parameters and plurality of priority indications in a neighbor list table (202).
