PROBLEM TO BE SOLVED: To provide a communication system that is a voice communication system using a network where a plurality of mobile radio terminals are allowed to simultaneously communicate through a radio base station connecting to the network and excellent speech communication is made without provision of a high performance CPU in the radio base station. SOLUTION: Voice data sent from a mobile terminal or an analog public network are fed to a data transfer section 130 via a terminal interface I/F section 100, stored once in a transmission ring buffer 122 of a transmission reception ring buffer section 120, and then sent to a data transmission section 140, from which the data are sent to a LAN 110. The voice data sent from the LAN 110 are once stored in a reception ring buffer 124 of the transmission reception ring buffer section 120 and sent to the mobile terminal or the analog public network via the data transfer section 130 and the terminal I/F section 100. |
