Abstract
A method of allocating time slots in a time division multiple access cellular telephone system increases the traffic capacity of a base station's RF channel. A method is provided for operating in half rate mode while maintaining adequate signal quality over the RF channel communications link between a base station and a mobile station. In full rate mode, each mobile station is allocated at least four of the twelve slots. For mobile stations experiencing little or no signal deterioration from other sources, a channel can be operated in half rate mode with little or no adverse effect to the signal quality. For mobile stations that are experiencing signal deterioration, the same channel can provide full rate mode support.
