Abstract
A radio communication method includes a step in which a MeNB (210) transmits a bearer setup instruction to establish a bearer including a first tunnel and a second tunnel based on a setup request, and a step in which a CN-UP (300) establishes the first tunnel and the second tunnel based on the bearer setup instruction. The CN-UP (300) sets the same identifiers to a TEID on the CN-UP (300) side of the first tunnel and a TEID on the CN-UP (300) side of the second tunnel.
Claims5
A radio communication system comprising:
- a master radio base station configured to perform radio communications with user device and control radio communications between the user device and a secondary radio base station;
- and
- a network device configured to establish a PDU session that includes a first tunnel to the master radio base station and a second tunnel to the secondary radio base station, wherein
- the master radio base station includes a controller that receives a setup request of the PDU session and, based on the setup request, transmits a setup instruction to establish the PDU session using the first tunnel and the second tunnel,
- the network device includes a tunnel setup section that sets same identifiers to a first tunnel endpoint identifier on a network device side of the first tunnel and a second tunnel endpoint identifier on a network device side of the second tunnel.
A network device configured to perform radio communications with user device and establish a PDU session that includes a first tunnel to a master radio base station which controls radio communications between the user device and a secondary radio base station, and a second tunnel to the secondary radio base station, the network device comprising:
- a transceiver that receives a setup instruction to establish the PDU session using the first tunnel and the second tunnel;
- and
- a processor, coupled to the transceiver, that sets same identifiers to a first tunnel endpoint identifier on a network device side of the first tunnel and a second tunnel endpoint identifier on a network device side of the second tunnel based on the setup instruction.
A radio communication method to be executed by using a master radio base station that performs radio communications with user device and controls radio communications between the user device and a secondary radio base station, and a network device that establishes a PDU session that includes a first tunnel to the master radio base station and a second tunnel to the secondary radio base station, the method comprising the steps of:
- receiving a setup request of the PDU session and, based on the setup request, transmitting a setup instruction to establish the PDU session using the first tunnel and the second tunnel, by the master radio base station, and
- setting, by the network device, same identifiers to a first tunnel endpoint identifier on a network device side of the first tunnel and a second tunnel endpoint identifier on a network device side of the second tunnel based on the setup instruction.
