Abstract: The present invention relates to a handover method that a current coordinator transfers a coordinating function of controlling a network to a different device configuring the network. The present invention relates to a method of selecting an optimal device as a coordinator in selecting the different device using priority information decided by a prescribed evaluation reference. And, the present invention relates to a method of simplifying a procedure in a manner of transmitting relevant information together with a handover request message. In a wireless network including a coordinator, a secondary coordinator is decided in advance. If the coordinator is suddenly unable to perform a function, the present invention relates to a method of enabling the function of the coordinator to be performed by the decided secondary coordinator. Thus, a process for transferring the coordinating function without the handover process is called a recovery process. The present invention relates to the recovery method and a method of deciding a secondary coordinator to perform a recovery. In the method of deciding the secondary coordinator, a method of deciding a more proper coordinator using information on coordinator priority is provided.

Abstract translation: 本发明涉及一种当前协调器将控制网络的协调功能传送到配置网络的不同设备的切换方法。 本发明涉及一种选择最佳设备作为协调器的方法，该方法是使用由规定评估参考决定的优先级信息来选择不同设备。 并且，本发明涉及以与切换请求消息一起发送相关信息的方式来简化过程的方法。 在包括协调器的无线网络中，预先确定辅助协调器。 如果协调器突然不能执行功能，本发明涉及一种能够由所确定的辅助协调器执行协调器的功能的方法。 因此，在没有切换处理的情况下传送协调功能的处理被称为恢复处理。 本发明涉及恢复方法和决定辅助协调器以执行恢复的方法。 在确定辅助协调器的方法中，提供了使用关于协调器优先级的信息来决定更合适的协调器的方法。
