Abstract:
A switching server 100 relays VoIP packets transmitted from a cellular phone terminal 300A to an IP phone terminal 42, and sequentially acquires the receiving times of the VoIP packets received from the cellular phone terminal 300A. In addition, the switching server 100 switches a communication route R1 via a radio IP network 10A to a communication route R2 via a radio IP network 10B, on the basis of the multiple receiving times thus acquired.
Abstract(Chinese):

切换服务器100将从蜂窝电话终端300A发送的VoIP分组中继到IP电话终端42，并且顺序地获取从蜂窝电话终端300A接收的VoIP分组的接收时间。 此外，切换服务器100基于由此获取的多个接收次数，经由无线IP网络10B经由无线IP网络10A将通信路由R1切换到通信路由R2。
