PURPOSE: A computer system having a call processing function on a TCP/IP(Transmission Control Protocol/Internet Protocol) and a call processing method therefor are provided to easily perform an interface with an other system by easily adding a specific function to a system for performing the call processing function and unifying an interface standard with the other system as a general TCP/IP standard. CONSTITUTION: A TCP/IP interface unit(101) receives various call processing messages with a TCP/IP standard from a BSC(Base Station Controller)(1), converts the call processing messages with an internal message standard, and outputs the call processing messages. The TCP/IP interface unit(101) receives various call processing messages, converts the call processing messages with the TCP/IP standard, and transmits the call processing messages to the BSC(1). An MGCP/UDP/IP(Media Gateway Control Protocol/User Datagram Protocol/IP) interface unit(102) receives various call processing message an MGCP/UDP/IP standard from a gateway(2), converts the various call processing messages into the call processing messages with an internal message standard, and outputs the call processing messages. The MGCP/UDP/IP interface unit(102) receives various call processing messages, converts the call processing messages into call processing messages with the MGCP/UDP/IP standard, and transmits the call processing messages to the gateway(2). An SIP/UDP/IP(Session Initialization Protocol/UDP/IP) interface unit(103) receives various call processing messages with an SIP/UDP/IP standard from a central call processing center(3), converts the call processing messages into call processing messages with an internal message standard, and outputs the call processing messages. The SIP/UDP/IP interface unit(103) receives various call processing messages, converts the call processing messages into call processing message with the SIP/UDP/IP standard, and transmits the call processing messages to the central call processing center(3).
