    • A method for updating a map in a navigation terminal via fusion of broadcasting and telecommunications includes: receiving map contents of the map from a broadcast center via a broadcast network; classifying the map contents received via the broadcast network into updatable map contents and un-updatable map contents which have dependencies with map contents having not been received by the navigation terminal; and updating the map using the updatable map contents. The method further includes requesting the broadcast center via a wired/wireless telecommunications network to download map contents of the map, which have not been received but have dependencies with the un-updatable map contents; receiving the requested map contents from the broadcast center via the wired/wireless telecommunications network; and updating the map by aggregating the un-updatable map contents with the requested map contents.
    • 一种用于通过广播和通信的融合更新导航终端中的地图的方法包括:经由广播网络从广播中心接收地图的地图内容; 将经由广播网络接收到的地图内容分类为与导航终端未接收到的地图内容具有依赖关系的可更新地图内容和不可更新地图内容; 以及使用可更新地图内容来更新地图。 该方法还包括通过有线/无线电信网络请求广播中心来下载未被接收但与不可更新的地图内容有依赖关系的地图的地图内容; 经由有线/无线电信网络从广播中心接收所请求的地图内容; 以及通过将不可更新的地图内容与所请求的地图内容聚合来更新地图。

    • Provided are an apparatus and method for improving transmission control protocol (TCP) performance using path recovery notification over a wireless network. The apparatus includes: a path recovery manager which detects a mobile host recovered from a temporary disconnection state and then outputs a detection signal to notify the detection result; a path recovery notification manager which receives the detection signal and generates an ACK (acknowledgement) packet to inform a transmitting end that the mobile host is recovered; and a first packet transceiver which transmits/receives the generated ACK packet and a data packet. Accordingly, a temporary disconnection state of a wireless network is explicitly informed to a transmitting end so as to transmit only lost packets without performing unnecessary congestion control, thereby improving TCP performance.
    • 提供了一种用于通过无线网络使用路径恢复通知来改进传输控制协议(TCP)性能的装置和方法。 该装置包括:路径恢复管理器,其检测从临时断开状态恢复的移动主机,然后输出检测信号以通知检测结果; 路径恢复通知管理器,其接收检测信号并生成ACK(确认)包以通知发送端移动主机被恢复; 以及发送/接收所生成的ACK分组和数据分组的第一分组收发机。 因此,无线网络的临时断开状态被明确地通知给发送端,以便仅发送丢失的分组而不执行不必要的拥塞控制,从而提高TCP性能。
