Patent ID: 11924082
Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATION
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A control device comprising one or more processors configured to:
acquire a current amount of communication of an accommodated user terminal from a relay device that notifies the current amount of communication when the current amount of communication exceeds an initial communication amount threshold value;
calculate a communication speed by using (i) the current amount of communication acquired and (ii) a notification interval from a) a time at which a previous amount of communication is acquired to b) a time at which the current amount of communication is acquired;
calculate an updated communication amount threshold value based on the communication speed, wherein calculating the updated communication amount threshold value comprises:
determining a first threshold value that is a multiplication value of the communication speed and a target notification period, the target notification period being between (1) the time at which the current amount of communication is acquired and (2) a time at which an updated amount of communication is acquired,
obtaining a second threshold value that is a predetermined amount of communication when a notification from the relay device is received at a fixed interval,
determining a smaller threshold value of the first threshold value and the second threshold value, and
setting the smaller threshold value as the updated communication amount threshold value; and

notify the relay device of the updated communication amount threshold value.
