MOBILE COMMUNICATION SYSTEM, RADIO BASE STATION, AND MOBILE STATION |
摘要 |
An appropriate action is taken when an abnormality in a layer 2 is detected, even in an “Inter-site CA” operation in which communication for a C-plane signal is performed in a cell #1 under a radio base station eNB#1 via a SRB, and communication for a U-plane signal is performed in a cell #11/#12 under a radio base station eNB#11/#12 via a DRB. In a mobile communication system according to the present invention, the radio base station eNB#11/#12 is configured to provide the radio base station eNB#1 with predetermined notification, when an abnormality is detected in a layer 2 of a downlink to a mobile station UE. |

1. A mobile communication system in which a mobile station is configured to be capable of performing carrier aggregation via a first cell under a first radio base station and a second cell under a second radio base station, wherein
the first radio base station is configured to be capable of transmitting and receiving a control signal and a data signal to and from the mobile station, the second radio base station is configured to be capable of transmitting and receiving a data signal and to be incapable of transmitting and receiving a control signal to and from the mobile station, and the second radio base station is configured to provide the first radio base station with predetermined notification, when an abnormality is detected in a layer 2 of a downlink to the mobile station. |
