Abstract
The present disclosure provides a radio station and a radio communication method capable of performing efficient control in Dual Connectivity. A radio station (10) includes: a classification unit (11) that classifies, when a data radio bearer is established with a communication terminal through a radio station (20), the data radio bearer into one of a plurality of groups based on a predetermined classification condition; and a transmission unit (12) that transmits, to the radio station (20), an establishment request message requesting establishment of the data radio bearer, and the group into which the data radio bearer is classified.
Claims10
A radio station comprising:
- at least one memory storing instructions;
- and
- at least one processor configured to execute the instructions to:
- classify, when a data radio bearer is established with a communication terminal through another radio station, the data radio bearer into one of a plurality of groups based on a predetermined classification condition;
- transmit, to the other radio station, an establishment request message requesting establishment of the data radio bearer, and the group into which the data radio bearer is classified;
- receive, from the other radio station, a data communication status notification message notifying about a status of downlink data communication in the other radio station;
- and
- control, when one of the plurality of the groups is included in the data communication status notification message, the data radio bearer classified into the group included in the data communication status notification message,
- wherein the data communication status notification message includes first information indicating whether control is performed per group into which respective radio bearers are classified, and further includes, when the first information indicates that control is performed per group, second information about a group to be controlled and third information indicating a control content for the data radio bearer classified into the group to be controlled, and
- wherein the at least one processor is further configured to execute the instructions to determine, based on the first information, whether one of the plurality of groups is included in the data communication status notification message, and perform the control content indicated by the third information with regard to the data radio bearer classified into the group included in the second information.

A radio station comprising:
- at least one memory storing instructions;
- and
- at least one processor configured to execute the instructions to receive, when a data radio bearer is established between a communication terminal and another radio station through the radio station, an establishment request message requesting establishment of the data radio bearer, and one of a plurality of groups into which the other radio station has classified the data radio bearer based on a predetermined classification condition, from the other radio station;
- determine a group to be controlled among the plurality of the groups based on at least one of a state of the radio station and a radio state between the radio station and the communication terminal;
- and
- transmit a data communication status notification message that includes the group to be controlled and that notifies about a status of downlink data communication in the radio station, to the other radio station,
- wherein the data communication status notification message includes first information indicating whether control is performed per group into which respective radio bearers are classified, and further includes, when the first information indicates that control is performed per group, second information about a group to be controlled and third information indicating a control content for the data radio bearer classified into the group to be controlled.

A radio communication method comprising:
- classifying, when a data radio bearer is established with a communication terminal through another radio station, the data radio bearer into one of a plurality of groups based on a predetermined classification condition;
- and
- transmitting, to the other radio station, an establishment request message requesting establishment of the data radio bearer, and the group into which the data radio bearer is classified;
- receiving, from the other radio station, a data communication status notification message notifying about a status of downlink data communication in the other radio station;
- and
- controlling, when one of the plurality of the groups is included in the data communication status notification message, the data radio bearer classified into the group included in the data communication status notification message,
- wherein the data communication status notification message includes first information indicating whether control is performed per group into which respective radio bearers are classified, and further includes, when the first information indicates that control is performed per group, second information about a group to be controlled and third information indicating a control content for the data radio bearer classified into the group to be controlled, and
- determining, based on the first information, whether one of the plurality of groups is included in the data communication status notification message, and performing the control content indicated by the third information with regard to the data radio bearer classified into the group included in the second information.
