Mobile communication system, communication system, control node, call-processing node, and communication control method

摘要

A mobile communication system includes a plurality of call-processing servers, a call processing management database that holds data necessary for call processing, and a network manager. The network manager comprises a node state recognition unit that recognizes states of the call-processing servers, and a control unit that determines the call-processing node that processes a call processing request based on the states. The call-processing server comprises a call processing request accepting unit that accepts a call processing request, an acquisition unit that acquires information of a mobile communication terminal related to the call processing request from the database, a call processing unit that performs call processing using the acquired information; and a call processing result storage unit that stores information of a result of the call processing in the database.

1. A mobile communication system that provides a mobile communication function to a mobile communication terminal and includes a plurality of call-processing nodes, a call processing management database that is communicatively coupled with each of the plurality of call-processing nodes via a communication path and holds data of each mobile communication terminal necessary for call processing, and a control node, wherein
the control node comprises circuitry configured to
recognize states of the plurality of call-processing nodes;select a call-processing node among the plurality of call-processing nodes for processing a call processing request from the mobile communication terminal based on the states of the plurality of call-processing nodes; andperform control so that the call processing request is directed to the selected call-processing node, and at least one call-processing node of the plurality of call-processing nodes comprises circuitry configured to
receive the call processing request or one or more other call processing requests as directed by the control node;acquire information of a corresponding mobile communication terminal related to the received call processing request from the call processing management database, each time a processing request is received or each time a processing request is received and the at least one call-processing node does not have valid information of the corresponding mobile communication terminal related to the received call processing request, the information comprising state information indicating whether the corresponding mobile communication terminal is in communication or at standby;perform call processing related to the received call processing request using the information; andstore information of a result of the call processing in the call processing management database.
