Abstract
A radio base station includes a mobile communication system, a first relay node and a radio base station connected via a radio bearer, a second relay node and a radio base station connected via a radio bearer, and a mobile station configured to conduct a handover process between a first and second state. In the first state a radio bearer is established with the first relay node in order to communicate via the first relay node and the radio base station. In the second state a radio bearer is established with the second relay node in order to communicate via the second relay node and the radio base station. The mobile station is configured such that control signals are transmitted and received via the radio bearer between the first relay node and the radio base station, via the radio bearer between the second relay node and the radio base station.
