Abstract: PURPOSE: A communication service control method and a system therefor are provided to transfer the connection of the present service network into a useful network by measuring the QoS of each communication network in an environment that communication networks, defined as respectively different protocols, interwork. CONSTITUTION: A wireline phone is registered in an adaptive gateway(S30). If a voice signal transmission request from the registered wireline phone to an IP network is generated(S31), a wireline communication channel is formed. The wireline phone transmits a 64kbps PCM signal through the wireline communication channel(S33). A vocoder in an adaptive controller converts the received 64kbps PCM signal into an 8kbps CDMA signal(S34). A packetizer/depacketizer converts the 8kbps CDMA signal into an IP packet and transfers it to the IP network(S35,S36). A QoS monitor/controller monitors the QoS of the IP network after the formation of the wireline communication channel for the wireline phone(S37). If the QoS of the IP network drops below the first threshold value continuously(S38), the QoS monitor/controller sends a seamless hand-off command to the controller of a selector and the controller of the adaptive controller(S39).
