A Voice/Data Integration MAC Protocol for Ku Band CDMA VSAT Networks
06 October 2003
Abstract- In this paper, a new multiple access protocol (MAC) that integrates both voice and data traffic in TDM/CDMA VSAT networks is proposed and investigated. Architecture of the VSAT network is described. In each VSAT, for voice traffic, voice active detect (VAD) is used, and for data traffic, WWW browsing traffic is considered.
Given a VSAT, data packet can be transmitted in the silence period of voice traffic, but when talkspurt comes, transmission of data traffic should be stopped and the channel should return to voice traffic. Dynamic code allocation strategy with QoS consideration is the key feature of this MAC protocol. Simulation results are given for pure voice call and voice/data integration traffic.
