Performance analysis of IP multimedia services over HSDPA mobile networks

3G wireless networks aim at supporting real-time multimedia applications such as multimedia conferencing. The 3rd Partnership Project (3GPP) has designed IP Multimedia Subsystem (IMS) as the solution to provide rich multimedia communication for the Next Generation Networks (NGN). Based on IETF standards such as IP, SIP and SDP protocols, it allows convergence of IP multimedia communications though existing IP networks. Interest in such communications is expected to grow over wireless network. To guarantee real-time and reliable multimedia transfer, there is a need to analyze multimedia traffic deployed over real 3G networks to help network operators identifying the required 3G IMS network capacity. Therefore, we propose to test real-time multimedia SIP communications through HSDPA network using G711 voice and H263 video codecs with different video frame rates. In this paper, we focus on media mean delay, jitter, packet loss and bandwidth use measurements with and without mobility.
