    • A method of adjusting quality of service (QoS) with respect to changes in a transmission environment of a mobile terminal receiving data based on a stream control transmission protocol (SCTP) session. When the transmission environment of the mobile terminal receiving data based on the SCTP session changes, the mobile terminal transmits link information indicating a new transmission environment to a destination node, and the destination node adjusts the quality of data or the size of a transmission window based on the link information. Thus, without adding separate network devices, the QoS of the data being transmitted can be adjusted with respect to the changed transmission environment, only by adding functions with software to the transmission terminal and the reception terminal. Also, since the destination node manually adjusts the transmission window according to the link information, packet loss can be minimized compared to the conventional congestion control method.
    • 一种基于流控制传输协议(SCTP)会话来调整接收数据的移动终端的传输环境中的变化的服务质量(QoS)的方法。 当移动终端基于SCTP会话接收数据的传输环境改变时,移动终端向目的地节点发送指示新的传输环境的链路信息,目的节点调整数据的质量或传输窗口的大小 关于链接信息。 因此,在不添加分离的网络装置的情况下,仅通过向发送终端和接收终端添加具有软件的功能,能够相对于变更的发送环境来调整正在发送的数据的QoS。 此外,由于目的地节点根据链路信息手动调整传输窗口,与传统的拥塞控制方法相比,分组丢失可以最小化。
