COMMUNICATION SYSTEM, CALL CONTROL DEVICE, BASE STATION DEVICE AND RECORDING MEDIUM
First Claim
1. A communication system for calling a plurality of terminal devices in response to a single request of call connection, assigning, for a single terminal device which answered the call, a communication band to be occupied in a communication band which can be used, and establishing the call connection in the assigned communication band, the communication system comprising:
- a deriving section that derives a communication band required for the call connection of each of the terminal devices to be called when the request of call connection is received;
a securing section that secures a communication band having the maximum width in each of the derived communication bands in the communication band which can be used; and
an assigning section that assigns a communication band to be occupied in the secured communication band to the terminal device which answered the call.
