Abstract

Measurement-based methods for the reassignment of a call to a time-slot with less cochannel interference on a time-division multiple access (TDMA) radio link are described and evaluated using discrete-event simulation. Portable radio access, transfer triggering, and time-slot selection are simulated using an integrated radio and traffic model. It was found that link quality can be maintained with a low transfer rate, even under heavy traffic load. Performance was robust with respect to trigger measurement error. Hysteresis reduced the transfer rate without noticeably affecting quality
