Abstract
A system and method for providing dynamic channel assignments in a microcellular system surrounded by a macrocellular system. The method characterizes the RF environment of the microcellular system and the macrocellular environment. Channels are then ranked according to the signal-to-interference ratio computed from the measured RF characteristics. A call is assigned to a highest ranked idle channel. All active calls are monitored to ensure voice quality and call performance by forcing hand-off to another channel before degradation occurs. In another embodiment, the system is self-configurable to changes in the macrocellular configuration by including remote power adjustment and remote Supervisory Audio Tone assignment functionality.
