Abstract
The present invention discloses a communication system supporting Circuit Switch (CS) and Packet Switching (PS), which includes several CS communication devices, an application device and at least one network communication device. The network communication device builds a connection with a PS communication unit of the application device through a network. When the CS communication devices communicate with a CS communication unit of the application device through a CS interface, a processing unit of the application device converts several voice signals transmitted between the CS communication devices and the at least one network communication device, such that the CS communication devices builds a voice connection with the at least one network communication device.
