Abstract

A radio base station includes a mobile communication system configured to transmit and receive a data signal between a mobile station and a gateway device via a relay node and a radio base station. The mobile communication system is configured such that the radio bearer for the mobile station is set between the mobile station and the relay node. The radio bearer for the relay node is set between the relay node and the radio base station. A network bearer for the mobile station is set between the relay node and the gateway device. The network bearer for a plurality of mobile stations is multiplexed in the radio bearer for the relay node, and a data signal is transmitted and received between the mobile station and the gateway device via the radio bearer for the mobile station and the network bearer for the mobile station.

Claims2

Dependent claims

A mobile communication system configured to transmit and receive a data signal between a mobile station and a gateway device via a relay node and a radio base station, the mobile communication system comprising:

a processor;
a memory operatively connected to the processor;
a radio bearer for the mobile station set between the mobile station and the relay node;
a radio bearer for the relay node set between the relay node and the radio base station;
an Evolved Packet System (EPS) bearer for the mobile station set between the mobile station and the gateway device, wherein the EPS bearer for a plurality of mobile stations is multiplexed in the radio bearer for the relay node;
a S1 bearer set between the radio base station and the gateway device without setting the S1 bearer between the relay node and the gateway device, wherein the S1 bearer is set independently for each mobile station;
and the data signal is transmitted by the processor and received between the mobile station and the gateway device via the radio bearer for the mobile station, the EPS bearer for the mobile station, and the S1 bearer set as for the mobile station.
