MOBILE COMMUNICATION SYSTEM, COMMUNICATION SYSTEM, CONTROL NODE, CALL-PROCESSING NODE, AND COMMUNICATION CONTROL METHOD

摘要

Redundancy of a call-processing node having excellent reliability, economic efficiency and flexibility can be realized. A mobile communication system 1 includes a plurality of call-processing servers 20, a call processing management database 10 that holds data necessary for call processing, and a network manager 40. The network manager 40 comprises a node state recognition unit 41 that recognizes states of the call-processing servers 20, and a control unit 42 that determines and controls the call-processing node that processes a call processing request based on the states. The call-processing server 20 comprises a call processing request accepting unit 21 that accepts a call processing request, an acquisition unit 22 that acquires information of a mobile communication terminal 50 related to the call processing request from the call processing management database 10, a call processing unit 23 that performs call processing using the acquired information; and a call processing result storage unit 24 that stores information of a result of the call processing in the call processing management database 10.
