Abstract
Disclosed embodiments include a method for establishing a wireless communication session between a base station unit and a mobile unit wherein a system controller determines which base station unit of multiple base station units is an optimal base station unit to establish the session. The method includes the system controller receiving commands from each of multiple BSUs that have received a request for wireless service from a mobile unit. The commands include information, such as a unique identifier for the sending BSU, signal strength information for the sending BSU, and channel availability for the sending BSU. The system controller directs the optimal BSU to respond to the request, and directs every other BSU to ignore the request. In at least one embodiment, Bluetooth commands are used.
