    • A technique is disclosed, according to which communication can be achieved with high efficiency by selecting access points to be connected based on the quality of end-to-end communication between a mobile node and a correspondent node when there are a plurality of access points. According to this technique, a mobile node 100 transmits to the access point a first message to request the selection of access points to be connected, and the access point, upon receipt of the first message, transmits a second message including specified information necessary for the selection of access points to be connected to a communication apparatus 108. A relay node, upon receipt of said message, updates the specified information based on a providable QoS information, transfers the updated second message to the communication apparatus, and in case another second message has been received subsequently and the relay node itself is a crossover node, optimal communication path between the mobile node and the communication apparatus is decided, and a third message is transmitted to notify the results of decision to the access point on the optimal communication path.
    • 公开了一种技术,根据该技术,当存在多个接入点时,可以通过基于移动节点和通信节点之间的端到端通信的质量选择要连接的接入点,以高效率来实现通信。 根据该技术,移动节点100向接入点发送第一消息,以请求对要连接的接入点的选择,并且接入点在接收到第一消息时,发送包括第 选择要连接到通信装置108的接入点。中继节点在接收到所述消息时,基于可提供的QoS信息更新指定的信息,将更新的第二消息传送到通信装置,并且在另一个第二消息 已经被接收到,并且中继节点本身是交叉节点,确定移动节点和通信装置之间的最佳通信路径,并且发送第三消息以在最佳通信路径上向接入点通知决定结果。
