INCOMING CALL FORWARDING METHOD AND INCOMING CALL FORWARDING SYSTEM

摘要

PROBLEM TO BE SOLVED: To transmit mutual terminal information when terminals connected to a circuit switching network transmit and receive bit stream through a packet exchange network.

SOLUTION: The terminal is a 3G-324M terminal of a 3GPP standard, and the bit stream is H. 223 recommended by ITU-T. A gateway which forwards the bit stream from a circuit switching network to a packet exchange network, divides the H. 223 bit stream received from the circuit switching network into specified lengths, and forwards it to the packet exchange network after changing it to a UDP packet. A gateway which forwards the bit stream from the packet exchange network to the circuit switching network receives the H. 223 bit stream having been changed to the UDP packet from the packet exchange network, and forwards the H. 223 bit stream that has been taken out of the UDP packet to the circuit switching network. The H. 223 bit stream can be divided for each MUX-PDU.
