METHOD AND APPARATUS FOR SELECTING THE BEST FIXED COMMUNICATION UNIT

摘要

A portable communication unit (120) capable to communicating on a plurality of communication channels. The portable communication unit (120) includes a method for selecting one of an at least two fixed communication units (102) for communicating therewith. The method comprises the steps of (a) transmitting communication link requests (602); (b) receiving link grant responses (608) from the fixed communication units receiving the communication link requests; (c) transmitting wait signals (610) for delaying communication to the fixed communication units (102) responding to the communication link requests; (d) measuring and storing signal strengths (614) of the link responses received from the fixed communication units (102) responding to the communication link requests; (e) selecting the fixed communication unit (620) having a maximum measured received signal strength of the link grant response; and (f) initiating communication (630) with the fixed communication unit (102) having the maximum received signal strength.
