SYSTEM AND METHOD OF ADAPATIVE MEDIA TRANSPORT CONTROL FOR VERTICAL HANDOVERS IN HETEROGENEOUS ACCESS NETWORKS

摘要

PURPOSE: An adaptive media transmission control method about the hand over between the heterogeneous networks is provided to control the smooth transmission of adaptive media by supplying terminal handover state information to an application layer. CONSTITUTION: An adaptive media transmission control method about the hand over between the heterogeneous networks comprises a step of deciding a target network(B) for a hand over among searched neighbor nodes in which a mobile terminal(10) is searched. The mobile terminal transmits a handover information to an adaptive media server(80). The adaptive media server controls transfer rate of the adaptive media server through the handover information. The mobile terminal performs the handover to the target net. The mobile terminal receives adaptive media from the adaptive media server.
