ENHANCED PREEMPTION WITHIN A MOBILE TELECOMMUNICATIONS NETWORK

摘要

A first mobile station (300A) within a particular service area is initially allocated (620) 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 (650). The first mobile station is thereafter re-allocated (660) to one of the two half-rate channels by an int ra- cell handover (550) or mode modify procedure. The other half-rate traffic channel then becomes available to effectuate a new call connection with a second mobile station (300B) and increases the call capacity associated with the serving BSC.
