A bandwidth reservation protocol for speech/data integration in TDMA-based advanced mobile systems

The traffic performance of third-generation mobile systems is greatly influenced by the multiple access protocols used in the radio access subsystem. The paper introduces an access protocol, SIR (Service Integration Radio Access), which has the potential for accommodating the requirements of speech and bursty data traffic in an efficient way. SIR is evolved from a protocol (PRMA ++) studied in the framework of a TDMA-based version of the European Universal Mobile Telecommunication System (UMTS) and uses dedicated mechanisms for data bandwidth request collection and servicing.
