The delay decrement method for voice/data traffic service in mobile system

摘要

Staggered frame method to lessen the transmission delay(queuing) between Base station Transceiver Subsystem and Base Station Controller subsystem in mobile system is suggested. In staggered frame method, transmit time of traffic is distributed over frame boundary. Four kinds of staggered frame method for integrated voice and data service are analyzed. Scheme I method is existing algorithm which does not discriminate between voice and data traffic during the assignment of channel. Scheme II and scheme III are suggested algorithm in this paper, in which voice and data traffic are processed differently each other. In scheme II, data and voice traffic can be assigned in the same offset slot, but voice traffic and data traffic are assigned different region in sub-frame. In scheme III, subframes are classified into two region, that is, some subframes are allocated exclusively to voice traffic, and the other slots are allocated exclusively to data traffic. According to the analysis results, scheme I, III are superior to scheme II as traffic load is increased.
