Conversion method of protocol conversion device and program for conversion of protocol protocol.

摘要

Conversion method of protocol conversion device protocol and program for conversion of protocol.In the communication of media via a packet switched network and a circuit switched network, a protocol conversion device for converting protocols between the packet switched network and the circuit switched network includes a call connection unit and a converter. The protocol.The connection unit executes processes call connection through communication media between terminals on the packet switched network and the circuit switched network. The protocol converter analyzes packets received from the packet switched network is to specify the bit rate of coding data of speech in speech packets.The protocol converter then specifies the key multiplex used in tables multiplexed in the circuit switched network from the bit rate coding. The protocol converter additionally generates tables using table multiplex which was specified for multiplexing data in load Useful packets received from the packet switched network and transmits to the circuit switched network.
