THIRD PARTY CALL CONTROL (3PCC) SYSTEM AND 3PCC IMPLEMENTATION METHOD IN AN IP COMMUNICATION NETWORK HAVING MULTIPLE IP ADDRESS SYSTEMS

摘要

PROBLEM TO BE SOLVED: To provide a technique to implement 3PCC in the case where an IP address system of a network having an application server installed with 3PCC is different from an IP address system of a network having a service control function.;SOLUTION: In an IP communication network, a first enterprise network 1 having an application server 10 installed with at least third party call control (3PCC) and a second enterprise network 4 having a service control function 42 have their respective different IP address systems. In a third party call control system in which a path of a control packet in an intercommunication between at least two communication devices via the application server 10 and a path of a media packet are allowed to be differed from each other, there is provided means 427 for setting a path such that the media packet has no intervention of the first enterprise network.;COPYRIGHT: (C)2009,JPO&INPIT
