A Study for Improving Handover Feasibility on Multi-Media Service in Convergence Networks

We propose the scheme to support continuously service when a user tries to contact new target network in convergence network even though the network has not enough the resource for service. The proposed scheme is based on the scalable service techniques for the encoding/decoding of service. When a user performs handover, the proposed scheme transforms original service capacity into suitable QoS for the target network and support handover for the user. Accordingly, we analyzed the performance of two schemes regarding the handover blocking probability using queuing system to show the improvement of performance by the proposed scheme. Subsequently, we showed that the handover blocking probability in the proposed scheme is lower than that in the existing scheme.
