    • The present invention relates to a method for changing a preamble in a moving network system, and a system for same. The method comprises the steps of: enabling a base station to select a relay, to change a preamble thereof, from at least two relays using a first preamble; enabling the selected relay to alternately transmit a signal using the first preamble and a signal using a second preamble to at least one terminal controlled by the selected relay; enabling the selected relay to judge whether the preamble of said at least one terminal is completely changed; and enabling the selected relay to transmit only the signal using the second preamble to said at least one terminal if the preamble is completely changed. The method for changing a preamble in a moving network system and the system for same according to the present invention minimizes communication cutoff time under the condition in which a mobile relay should change a preamble, to thereby effectively provide all terminals with information without a loss, and improve the utilization of a moving network.
    • 本发明涉及一种用于改变移动网络系统中的前同步码的方法及其系统。 该方法包括以下步骤:使基站能够使用第一前同步码从至少两个中继站中选择一个中继站,以改变其前导码; 使所选择的继电器使用第一前同步码交替发送信号,以及使用第二前导码向由所选择的继电器控制的至少一个终端发送信号; 使所选择的继电器能够判断所述至少一个终端的前导码是否完全改变; 以及如果所述前同步码完全改变,则使所选择的中继仅使用所述第二前导码发送所述至少一个终端的信号。 根据本发明的用于改变移动网络系统中的前导码及其系统的方法在移动中继应改变前导码的条件下最小化通信切断时间,从而有效地向所有终端提供信息而不丢失, 并提高移动网络的利用率。
