A communication system is provided having at least one radio base station with a voice data processing function. The station can communicate with plural mobile radio terminal equipment and has a call control function and protocol conversion function for converting a protocol between the LAN protocol and a mobile radio terminal equipment protocol. A circuit controller is provided also having call control function for controlling communication between the radio base station and the other terminal equipment which is connected to the wired LAN network. The circuit controller directs the radio base station to carry out call control and also includes communication control means for managing a communication path between the radio base station and the other terminal equipment. Voice data is transmitted between the radio base station and the other terminal equipment through the wired LAN network. However, the voice data transmitted between the radio base station and the other terminal equipment does not pass through the circuit controller.
