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.
Claims17
An UE (User Equipment) comprising:
- a memory;
- and
- one or more processors, comprising hardware, configured to:
- send an Attach Request message to a MME (Mobility Management Entity) during an Attach procedure, the Attach Request message including first information indicating that the UE supports dual connectivity with a master base station providing E-UTRA (Evolved UTRA (Universal Terrestrial Radio Access)) and a secondary base station providing radio communication scheme in 5G;
- receive an Attach Accept message from the MME during the Attach procedure, the Attach Accept message including second information indicating whether use of dual connectivity with the radio communication scheme in 5G is restricted or not;
- and
- receive a RRC Connection Reconfiguration message from the master base station during-a Secondary Node Addition procedure for operating the dual connectivity, the RRC Connection Reconfiguration message being received after receiving the Attach Accept message.
A MME (Mobility Management Entity) comprising:
- a memory;
- and
- one or more processors, comprising hardware, configured to:
- receive, by the MME, an Attach Request message from an UE (User Equipment) during Attach procedure, the Attach Request message including first information indicating that the UE supports Dual Connectivity with a master base station providing E-UTRA (Evolved UTRA (Universal Terrestrial Radio Access)) and a secondary base station providing radio communication scheme in 5G;
- decide whether or not to restrict use of dual connectivity with the radio communication scheme in 5G for the UE, based on the first information and second information;
- and
- send an Attach Accept message to the UE during the Attach procedure, the Attach Accept message including the second information indicating whether use of dual connectivity with the radio communication scheme in 5G is restricted or not.
A master base station providing E-UTRA (Evolved UTRA (Universal Terrestrial Radio Access)), the master base station comprising:
- a memory;
- and
- one or more processors, comprising hardware, configured to:
- receive, by the master base station, an Attach Request message from an UE (User Equipment);
- send the Attach Request message to a MME (Mobility Management Entity) 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 radio communication scheme in 5G;
- receive an Attach Accept message from the MME;
- send the Attach Accept message to the UE during the Attach procedure, the Attach Accept message including second information indicating whether use of dual connectivity with the radio communication scheme in 5G is restricted or not;
- and
- send a RRC Connection Reconfiguration message to the UE during a Secondary Node Addition procedure for operating the dual connectivity, the RRC Connection Reconfiguration message being sent after sending the Attach Accept message.
A method for an UE (User Equipment) the method comprising:
- sending an Attach Request message to a MME (Mobility Management Entity) during Attach procedure, the Attach Request message including first information indicating that the UE supports dual connectivity with a master base station providing E-UTRA (Evolved UTRA (Universal Terrestrial Radio Access)) and a secondary base station providing radio communication scheme in 5G;
- receiving an Attach Accept message from the MME during the Attach procedure, the Attach Accept message including second information indicating whether use of dual connectivity with the radio communication scheme in 5G is restricted or not;
- and
- receiving a RRC Connection Reconfiguration message from the master base station during a Secondary Node Addition procedure for operating the dual connectivity, the RRC Connection Reconfiguration message being received after receiving the Attach Accept message.
