Method and apparatus for resolving multiple call accesses in a wireless communication system
First Claim
1. A method of resolving multiple cell accesses in a cellular system comprising the steps of:
- receiving a signal at a base transceiver station;
measuring a characteristic of the signal;
comparing the signal characteristic to a predefined threshold associated with cell size and co-channel access level;
sending a request to send another signal if the signal characteristic is less than the predefined threshold; and
automatically establishing a communication channel if a response to the request is received at the base transceiver station.

Abstract
A base transceiver station has a signal strength receiver and is capable of transmitting a directed retry signal. A processor connects to the signal strength receiver and compares a received signal strength to a predefined threshold. The processor causes the base transceiver station to send the directed retry signal if the received signal strength is less than the predefined threshold. A method is provided where a characteristic of a signal received at a base transceiver station is measured and compared to a predefined threshold. A directed retry is sent if the signal characteristic is less than the predefined threshold, and a communication channel is established if a response to the directed retry is received at the base transceiver station.
