Methods and systems for allocating a cellular communications channel for communication between a cellular terminal and a telephone base station using received signal strength measurements
First Claim
1. A method for allocating a cellular communications channel for communication between a cellular terminal and a telephone base station, the telephone base station connecting a wire telephone network to the cellular terminal within a local region in a cell of a wide area cellular network which uses a plurality of control channels and communications channels within a cellular network spectrum, said allocating method comprising the steps of:
- controlling said cellular terminal to measure received signal strengths of the control channels;
identifying a set of communications channels associated with a measured control channel having lowest received signal strength;
causing said cellular terminal to measure received signal strengths of the set of communications channels;
selecting from said set of communications channels, a communications channel having lowest received signal strength; and
using the selected communications channel having lowest received signal strength for communication between said cellular terminal and said telephone base station within the local region.

Abstract
A cellular communications channel is allocated for communication between a cellular terminal and a telephone base station wherein the telephone base station connects a wire telephone network to the cellular terminal within a local region in a cell of a wide area cellular network which uses a plurality of control channels and communications channels within a cellular network spectrum, by controlling the cellular terminal to measure the received signal strengths of the control and communications channels. The cellular terminal is controlled to measure received signal strengths of the control channels. A set of communications channels associated with measured control channel having lowest received signal strength is identified. The cellular terminal is then caused to measure the received signal strengths of the set of communications channels. A communications channel having the lowest received signal strength is selected from the set of communications channels. The selected communications channel having lowest received signal strength is used for communication between the cellular terminal and the telephone base station within the local region. The selected communications channel reduces co-channel interference between the telephone base station and the wide area cellular network and also reduces co-channel interference among the telephone base stations themselves.
