    • A method is provided for receiving a Digital Multimedia Broadcasting (DMB) signal by a mobile terminal in a DMB system including a satellite for transmitting a satellite DMB signal directly to the mobile terminal, a gap filler for repeating the satellite DMB signal received from the satellite and transmitting a terrestrial DMB signal to the mobile terminal, and the mobile terminal capable of receiving both the satellite DMB signal and the terrestrial DMB signal. The method includes receiving at least one DMB signal; determining if there is a satellite DMB signal among the at least one DMB signal; if there is the satellite DMB signal calculating a reception frequency of the satellite DMB signal for a stated time; and if the reception frequency is less than or equal to a threshold providing a user with a message recommending detachment of an antenna used for receiving the satellite DMB signal.
    • 提供了一种用于在包括用于将卫星DMB信号直接发送到移动终端的卫星的DMB系统中的移动终端接收数字多媒体广播(DMB)信号的方法,用于重复从卫星接收的卫星DMB信号的间隙 以及向移动终端发送地面DMB信号,以及能够接收卫星DMB信号和地面DMB信号的移动终端。 该方法包括接收至少一个DMB信号; 确定所述至少一个DMB信号中是否存在卫星DMB信号; 如果卫星DMB信号在规定时间内计算卫星DMB信号的接收频率, 并且如果接收频率小于或等于为用户提供推荐用于接收卫星DMB信号的天线的分离的消息的阈值。

    • Provided are a method for measuring characteristics of a path between nodes by using active testing packets based on priority, i.e., an inter-node path characteristic measuring method, which can measure and provide characteristics of a generated node, when an inter-node data transmission path is generated based on Multi-Protocol Label Switching (MPLS) to provide a path with satisfactory transmission delay, jitter and packet loss that are required by a user, and to provide a computer-readable recording medium for recording a program that implement the method. The method includes the steps of: a) synchronizing system time of the nodes with a global standard time; b) forming each testing packet; c) registering frame sequence and the global standard time during transmission; and d) calculating transmission delay time, jitter and packet loss by using time stamp and packet sequence information of a frame received by the destination node and transmitting the result to the management system.
    • 提供了一种通过使用基于优先级的活动测试分组来测量节点之间的路径的方法,即节点间路径特征测量方法,其可以在节点间数据传输时测量和提供生成节点的特性 基于多协议标签交换(MPLS)生成路径,以提供用户所需的令人满意的传输延迟,抖动和分组丢失的路径,并提供用于记录实现该方法的程序的计算机可读记录介质 。 该方法包括以下步骤:a)使节点的系统时间与全局标准时间同步; b)形成每个测试包; c)在传输期间注册帧序列和全局标准时间; 以及d)通过使用由目的地节点接收的帧的时间戳和分组序列信息来计算传输延迟时间,抖动和分组丢失,并将结果发送到管理系统。
