20120093125 | MOBILE COMMUNICATION SYSTEM - A radio base station includes a mobile communication system, a first relay node and a first radio base station connected via a radio bearer, a second relay node, and a second radio base station connected via a radio bearer. The first radio base station and the second radio base station are connected via a bearer, in which a mobile station is configured so as 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. In the second state a radio bearer is established with the second relay node in order to communicate. The mobile station is configured such that in the handover process, control signals are transmitted and received via the radio bearer between the first relay node, first radio base station, second radio base station, and second relay node. | 04-19-2012 |
20120094669 | MOBILE COMMUNICATION METHOD AND RADIO ACCESS NETWORK DEVICE - A radio base station includes a step-A where a second radio access network device inside a second radio access network notifies a first radio access network device inside a first radio access network of access information comprising at least one of either load information or barring information. Step-B includes a mobile station on standby in a cell under the first radio access network device, upon moving to an area in which the cell under the first radio access network device and the cell under the second radio access network device overlap, transmits a communication initiation request signal to the first radio access network device. Step-C includes the first radio access network device decides regarding in which of the cell under the first radio access network device or the cell under the second radio access network device. The communication of the mobile station should be initiated based on the access information. | 04-19-2012 |
