Description
Summary:Regardless of the fact that convergence is a way to evolve existing fixed and mobile networks towards NGN, the behavior of IP packet transmissions over mobile networks differs considerably from that for fixed networks. In IP- based FMC (fixed mobile convergence) networks, the fluctuation ranges of the network QoS metrics observed by the NGN terminals are remarkably large. In this respect, it is difficult to estimate the real end-to-end QoS metrics and to control the services properly between the NGN terminals, considering the end-user QoE. In this paper, for FMC services, we provide a service control scheme for RACF (Resource and Admission Control Functions) based on the end-user QoE predicted by the per-segment based observation method of the network QoS metrics using RTP/RTCP [1J. In IP-based FMC networks, the proposed scheme can be applied to all general NGN services provided by RTP/RTCP. The proposed scheme is closely related to the study of ITU-T draft Recommendation Y.MPM [2] and ITU-T Recommendation Y.2111 [3] R2 in ITU-T SG 13.
