Abstract :
We present a network architecture of the hybrid multimedia mobile access communication (MMAC) system through which a number of broadband multimedia mobile communication services are provided for hand-held, small radio terminals. In the hybrid MMAC system, the conventional personal communication system (PCS) link is used for uplinks while the broadband radio link under development in the MMAC Promotion Council is utilized for downlinks. The hybrid MMAC system has a lot of advantages such as the small terminal size, the low terminal cost and the smooth introduction of the full standard MMAC system, which is a bi-directional broadband system. In this paper, the concept and the network architecture of the hybrid MMAC system are presented. The protocol stacks and the operation sequences of this system are also described
