<P>PROBLEM TO BE SOLVED: To shorten the time of call processing by parallelization of a call processing sequence. <P>SOLUTION: A call processing parallelization system 1 has an INVITE request originated from a terminal 20A received by a signal distribution device 12 via a P-CSCF 11A. The signal distribution device 12 duplicates the received INVITE request and sends it to an originator CSCF 10A and a destination CSCF 10B. The originator CSCF 10A and the destination CSCF 10B respectively perform a parallel processing on the received INVITE request, and sends the INVITE request to an originator-destination processing completion confirmation device 13 after the completion of the parallel processing. Also, the originator-destination processing completion confirmation device 13 sends the INVITE request to a destination terminal 20B via a P-CSCF 11B when it receives the INVITE request respectively from the originator CSCF 10A and the destination CSCF 10B. <P>COPYRIGHT: (C)2012,JPO&INPIT |
