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.
Claims10
A User Equipment, UE, comprising:
- at least one memory storing instructions, and
- at least one processor configured to execute the instructions to;
- send an Attach Request message to a Mobility Management Entity, MME, via a mater base station providing a first radio access technology other than 5G, during an Attach procedure, the Attach Request message including first information indicating that the UE supports dual connectivity with the mater base station and a secondary base station providing a 5G wireless communication method as a secondary radio access technology;
- receive an Attach Accept message from the MME, via the master base station, during the Attach procedure, the Attach Accept message including second information indicating whether the use of dual connectivity with the 5G wireless communication method is restricted;
- and
- configure the dual connectivity with the 5G wireless communication method as the secondary radio access technology in a case where the second information indicates that the use of the dual connectivity with the 5G wireless communication method is not restricted.
A method of a User Equipment, UE, comprising:
- sending an Attach Request message to a Mobility Management Entity, MME, via a mater base station providing a first radio access technology other than 5G, during an Attach procedure, the Attach Request message including first information indicating that the UE supports dual connectivity with the master base station and a secondary base station providing a 5G wireless communication method as a secondary radio access technology;
- receiving an Attach Accept message from the MME, via the master base station, during the Attach procedure, the Attach Accept message including second information indicating whether the use of dual connectivity with the 5G wireless communication method is restricted;
- and
- configuring the dual connectivity with the 5G wireless communication method as the secondary radio access technology in a case where the second information indicates that the use of the dual connectivity with the 5G wireless communication method is not restricted.
