  • Publication number: 20110255512
    Abstract: A system and method of controlling transmission of adaptive media over handover performed between heterogeneous networks are disclosed. When a mobile terminal moves, it detects the necessity of handover between the heterogeneous networks, determines a target network to which it may perform handover, and transmits handover information to an adaptive media server that controls a transmission rate of adaptive media to previously inform about the handover. Then, the adaptive media adjusts a transmission rate of the adaptive media by using the received handover information, and when the mobile terminal performs handover to the target network, it can receive the adaptive media from the adaptive media server. Accordingly, when the mobile terminal using a real time multimedia service in a wireline/wireless environment in which various accessing techniques are integrated performs handover between heterogeneous networks, a change in quality of experience (QoE) sensed by subscribers due to the handover can be reduced.
