Soft Switch Performing Call Processing Using Load Sharing Technique and Its Call Processing Method

摘要

The present invention discloses a soft switch and a call processing method in the soft switch.;A soft switch for performing call processing using the load sharing scheme of the present invention executes an application server (AS) for interworking with a circuit-switched network and performs a connection configuration with a signal gateway (ASP). ASP unit having a; An ASP management unit receiving and managing status information from the plurality of ASPs and determining an ASP to be in charge of call processing when a call processing request is generated according to the status information; The ASP in charge of the call processing determined by the ASP management unit by allocating a unique local port to the ASPs, connected to the ASPs through the local port, and changing a call processing message according to a protocol for signaling in the circuit-switched network. Protocol processing unit for transmitting and receiving; A protocol processor connected to the ASPs through the local port and converting a message for call processing according to a protocol for signal transmission in the circuit switched network; An AS manager for managing routing-related information for distinguishing incoming signaling points; And an interface unit that manages the IP address of the signal gateway and is connected to an IP network to convert a call processing message into an IP packet and transmit the converted IP packet to the signal gateway.
