Abstract :
The capacity of CDMA systems is determined by the number of channel elements (CE) or the amount of interference. Cell overloading may arise due to CE shortage in spite of low interference. We propose an improved soft handoff control which solves the cell overloading by contracting the soft handoff region. The extent of the handoff region contraction is determined by considering the amount of adjacent-cell interference and the extent of traffic congestion simultaneously
