    • 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.
    • 公开了一种在异构网络之间执行的跨越切换的自适应媒体的传输控制系统和方法。 当移动终端移动时,它检测异构网络之间切换的必要性,确定其可以执行切换的目标网络,并将切换信息发送到控制自适应媒体的传输速率的自适应媒体服务器,以便先前通知 交出。 然后,自适应媒体通过使用接收到的切换信息来调整自适应媒体的传输速率,并且当移动终端执行到目标网络的切换时,它可以从自适应媒体服务器接收自适应媒体。 因此,当在各种接入技术集成的有线/无线环境中使用实时多媒体业务的移动终端执行异构网络之间的切换时,可以减少由于切换而由用户感知的体验质量(QoE)的变化 。
