摘要：A normal audio communication terminal can use the VoIP technology in amobile communications system by using an audio communication circuit for a
conventional wireless circuit, and adding an audio communications function to a packetcommunication device. In a PS (packet switching) network side forming a core network inthe mobile communications system, the signaling of a CS (circuit switching) call with anRNC is designed to control a CS-UP (CS side user plane) by communications with the CPUof an SGSN, and the user data relating to a CS call is designed for communications with aPSTN (public switch telephone network) by way of an MGW through the CS-UP. Thus, anaudio communication function can be added to a packet communication device, therebyrealizing a VoIP function to a wireless circuit using an audio communications circuit.
