CROSSOVER NODE SELECTION METHOD, AND RELAY NODE USED IN THE METHOD

摘要

PROBLEM TO BE SOLVED: To provide a crossover node selection method and the like capable of evading the double reservation of resources and minimizing the interruption of QoS by handover. SOLUTION: The crossover node selection method includes: a step of having the relay node which receives an acquisition message for acquiring the information of the crossover node of each of a plurality of network layers judge whether or not the relay node itself is the crossover node of one of the plurality of network layers and transmit the acquisition message to which the information of itself is inserted to an adjacent relay node when judging that it is the crossover node; a step of having a communication terminal 101 which receives the acquisition message to which the information of the crossover node of each of the plurality of network layers is inserted transmit a response message including the information inserted to the acquisition message to a mobile terminal 100; and a step of having the mobile terminal select one crossover node on the basis of the information inserted to the response message.
