Abstract:
The 4th Generation of mobile communication networks will use heterogeneous wireless technologies. Voice and low quality video flows will consist of very small IP packets, for which the standard RTP/UDP/IP headers constitute a significant overhead. Considering that the radio resources are scarce, this overhead may be unacceptable and the adoption of header compression mechanisms is desirable. This paper presents a solution for including RoHC header compression mechanisms within 4G networks; the solution is combined with the mechanisms required to provide QoS to the real time flows.
