Abstract
A first mobile station within a particular service area is initially allocated with a full-rate traffic channel. When congestion occurs within the serving base station controller (BSC) and no traffic channel is available for further allocation, the full-rate traffic channel previously allocated to the first mobile station is divided into two half-rate channels. The first mobile station is thereafter re-allocated to one of the two half-rate channels by an intra-cell handover or mode modify procedure. The other half-rate traffic channel then becomes available to effectuate a new call connection with a second mobile station and increases the call capacity associated with the serving BSC.
