Abstract

A method of identifying a proximal base site of a number of base sites by a communication unit in a CDMA communication system having a number of communication resources. The communication unit identifies the proximal base site by detection and measurement of identification signals received from the base sites where each base site transmits an identification signal containing at least an ID on a communication resource defined by parameters stored within a resource table within a memory unit within the communication unit with such stored parameters including a code key, a bandwidth, and a frequency and wherein at least some resources may be frequency coextensive. The method includes the steps of selecting a resource from the resource table within the memory of the communication unit and detecting and decoding to produce an ID from a detected identification signal by the communication unit on the resource. The method also includes the step of measuring signal strength by the communication unit of the detected identification signal to produce a magnitude value and storing the value and the ID in a signal strength table within the memory of the communication unit. The communication unit then increments to a next resource within the resource table and repeats the previous steps. The communication unit finally identifies the proximal base site by determining a highest relative signal strength stored within the signal strength table and recovering the ID stored therewith.
