MOBILE COMMUNICATION SYSTEM AND METHOD

摘要

PROBLEM TO BE SOLVED: To reduce the number of signalings in providing a real-time communication service between a plurality of mobile terminals.SOLUTION: A plurality of replication destination mobile terminals 12 for replicating a real-time medium being received by a replication indication mobile terminal 11 itself is indicated to a service control network 4. A resource securing request for the plurality of replication destination mobile terminals is transmitted from the service control network 4 that has received a replication destination indication request to a resource management node 32. Control is exerted on an S-GW 33 and a P-GW 34 by the resource management node 32 that has received the resource securing request so that resources for the plurality of replication destination mobile terminals are collectively secured on the basis of the resource securing request. After the resources for the plurality of replication destination mobile terminals are collectively secured by the S-GW 33 and P-GW 34, a process for replicating the real-time medium is executed from the service control network 4 on each of the plurality of replication destination mobile terminals via an IP mobile transmission network 3.
