Abstract
In future all IP cellular system, the requirement in terms of voice quality and spectrum efficiency for voice over IP services will reasonably be similar to current requirement on the circuit switched voice services. Hence, comparing with payload, the relatively large IP/UDP/RTP headers of wireless VoIP must be reduced in size by header compression. This paper detailedly analyzes two main header compression algorithms used in current wireless VoIP services. By simulation, the performance of these algorithms in cellular links is evaluated and compared.
