Abstract

In order to provide a communication system capable of charging control in accordance with a bearer used by a UE even when the UE performs dual connectivity, a communication system according to the present disclosure includes a communication terminal (11) configured to communicate with a communication device (12) and a communication device (13) by using a different radio bearer for each of the communication device (12) and the communication device (13), and a control device (14) configured to determine whether to cause the communication device (12) to measure the traffic of each radio bearer.

Claims

1-21. -21. (canceled)

22. A communication terminal comprising:
