The Inter-system handover between UMTS and GSM is one of the key features in the third generation UMTS cellular system. The compressed mode, with variable transmission gaps and power levels, is standardized to support the inter-frequency/system handover. In this article, a capacity-based compressed mode algorithm which considers potential impacts on the capacity and the priority of operating the compressed mode measurement is proposed to reduce the use of system resources while maintaining the UMTS-to-GSM border-cell handover quality. The performance of the proposed algorithm will be studied based on UMTS simulation platform.

The Inter-system handover is one of the key features in third generation cellular systems. The compressed mode, with variable transmission gaps and power levels, is standardized to support inter-frequency/inter-system handover. To optimize the system resources while maintaining the border-cell handover quality, a capacity-based compressed mode algorithm is proposed. Considering the tradeoff between the capacity and the connection quality, the algorithm can adaptively manage the compressed mode operation based on the potential impacts on the capacity and the efficiency of the compressed mode measurement. The performance will be studied based on UMTS simulation platform.
