Abstract :
Recently, mobile communication systems have supported various services including voice, data, video, and multimedia services as they evolve toward 3G. An AAL2 multiplexing scheme is introduced for transmission link efficiency in the UTRAN (UMTS terrestrial radio access network). However, limited radio resources and various quality of services (QoS) make it difficult to guarantee QoS requirements at radio access networks. The conventional AAL2/ATM multiplexing systems focused on link efficiency in multiplexing real-time voice and nonreal-time data traffic. In this paper, we classify various services into four classes according to QoS requirements and propose AAL2/ATM multiplexing schemes using statistical multiplexing and scheduling to guarantee the given requirements. Simulation results show that the proposed schemes perform better than the conventional schemes in guaranteeing QoS requirements of various services.
