Radio base station and mobile station
Priority control is performed using FPIs. A radio base station eNB according to the present invention includes: a bearer management unit 12 configured to manage FPIs assigned to data flows received from a core network device S-GW via an S1 bearer; and a priority control unit 13 configured to perform priority control over the data flows received from the core network device S-GW via the S1 bearer, in which the bearer management unit 12 establishes a radio bearer with a mobile station UE for each of the FPIs, and the priority control unit 13 transfers each data flow received from the core network device S-GW via the S1 bearer, to the radio bearer corresponding to the FPI assigned to the data flow.
1. A radio base station comprising: a processor that manages flow priorities assigned to data flows received from a core network device via an S1 bearer; wherein the processor performs priority control over the data flows received from the core network device via the S1 bearer, the processor establishes a radio bearer with a mobile station for each of the flow priorities, and the processor transfers each data flow received from the core network device via the S1 bearer, to the radio bearer corresponding to the flow priority assigned to the data flow, and a transmitter that transmits the data flow via the radio bearer to the mobile station.
2. A mobile station comprising: a processor that manages flow priorities assigned to data flows to be transmitted to a radio base station via radio bearers; wherein the processor performs priority control over the data flows to be transmitted to the radio base station via the radio bearers, processor establishes a radio bearer with the radio base station for each of the flow priorities, and the processor transfers each data flow to the radio bearer corresponding to the flow priority assigned to the data flow, a transmitter that transmits the data flow to the radio base station via the corresponding radio bearer.
3. A radio base station comprising a processor that performs priority control in a PDCP layer over a data flow received from a core network device, wherein the processor manages a flow priority assigned to the data flow received from the core network device and a priority in the PDCP layer in association with each other, and the processor performs priority control over the data flow received from the core network device, based on the priority in the PDCP layer that is associated with the flow priority assigned to the data flow.
4. The radio base station according to claim 3 , wherein the processor performs priority control over a data flow not assigned the flow priority, based on a predefined priority in the PDCP layer.
5. The radio base station according to claim 3 , further comprising a transmitter that notifies a mobile station of information associating the flow priority and the priority in the PDCP layer with each other.
6. A mobile station comprising a processor that performs priority control in a PDCP layer over a data flow to be transmitted to a radio base station, wherein the processor performs priority control over the data flow to be transmitted to the radio base station, based on a priority in the PDCP layer that is associated with a flow priority assigned to the data flow, and a transmitter that transmits the data flow to the radio base station.
7. The mobile station according to claim 6 , wherein the processor performs priority control over a data flow not assigned the flow priority, based on a predefined priority in the PDCP layer.
8. The radio base station according to claim 4 , further comprising a transmitter that notifies a mobile station of information associating the flow priority and the priority in the PDCP layer with each other.
