摘要:
A radio base station including a mobile communication system, a first relay node and a second relay node which are connected via a radio bearer, the second relay node and a radio base station which are connected via a radio bearer, where a mobile station is configured to perform a handover process between a first state, in which a radio bearer is set with the first relay node in order to communicate via the first relay node, the second relay node, and the radio base station, and a second state, in which a radio bearer is set with the radio base station in order to communicate via the radio base station, and a mobile station is configured such that during the handover process. Control signals involved in the handover process are sent and received via the radio bearer between the first relay node and the second relay node and via the radio bearer between the second relay node and the radio base station.

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.

A radio network controller can set up a connection with a mobile station located in a specific cell under control of the radio network controller. The radio network controller includes a connection setup request transmitter configured to transmit a connection setup request for request to set up the connection to the mobile station located in the specific cell; and a judger configured to judge whether or not to need to acquire information of the mobile station located in the specific cell. The connection setup request transmitter is configured to transmit the connection setup request to the mobile station located in the specific cell, when the judger judges to need to acquire the information of the mobile station.

A method for transmitting a notification signal comprises a step in which each of a plurality of mobile stations (UE) compares first security information which each of the mobile stations manages with second security information included in a received first notification signal to thereby verify the validity of the first notification signal and a step in which each of the mobile stations (UE) performs the output corresponding to the first notification signal in the case of successfully verifying the validity of the first notification signal.
摘要:
Provided is a mobile communication method including: a step in which a first radio base station S-eNB transmits a handover instruction which instructs a mobile station UE performing communication via a first cell under control of a first radio base station SeNB, so as to perform a handover to a second cell under control of a second radio base station TeNB; a step in which the mobile station UE performs a handover from the first cell to the second cell in accordance with the handover instruction; a step in which the mobile station UE acquires a global cell ID which can uniquely identify a second cell in at least one mobile communication system; and a step in which the mobile station UE reports a global cell ID which can uniquely identify the acquired second cell, to a position information management server.
