%X When transporting real-time IP services such as VoIP in a cellular communication system with limited channel bandwidth and high bit error rate, there exist some problems such as the relatively large overhead imposed by protocol headers and poor data discarding policies. In this paper, a new scheme, ROHC/UDP Lite, is proposed to solve these problems, which combines ROHC with UDP Lite protocol effectively. With the ROHC/UDP Lite, it is possible to efficiently transport IP-based packet-switched voice services in the future IP cellular systems.
