Abstract :
An AAL2 link transmission scheme is considered as a promising bandwidth-efficient voice/data transmission method in BS-BSC links of third generation radio access networks. To guarantee low delay requirement of voice traffic, voice delay restriction methods are introduced in the AAL2 link transmission scheme. That is, a timer is used in the loading of voice ATM cell payload for limiting cell packetization delay, and a voice/data ATM cell multiplexing scheme with priority in voice ATM cells is introduced in order to reduce queueing delay in a voice ATM cell multiplexing buffer. A mobile voice/data input traffic model is introduced and the performance of the proposed AAL2 link transmission scheme is evaluated in terms of average voice and data link delays, link efficiency, and ATM cell overhead ratio
