摘要:
The present invention relates to a mobile communication method in which a mobile station performs a handover from a handover source radio base station to a handover target radio base station. The mobile communication method includes the steps of: (A) acquiring, at the handover target radio base station, from the handover source radio base station or a switching center, a key for calculating a first key for generating a certain key used in a communication between the handover target radio base station and the mobile station; and (B) acquiring, at the handover target radio base station, from the switching center, a second key for calculating a first key for generating a certain key used in a communication between a next handover target radio base station and the mobile station.

A radio base station includes a mobile communication system, a relay node and a radio base station connected via a radio bearer. A mobile station is configured to perform a handover process between a state in which a radio bearer is set with the relay node so as to communicate via the relay node and the radio base station, and a state in which a radio bearer is set with the radio base station so as to communicate via the radio base station. The handover process is configured such that a data signal is transferred via the radio bearer between the relay node and the radio base station.

A mobile communication method according to the present invention includes: a step in which a mobile management node MME generates a key Kx using a key KASME1 and a key KASME2, the key Kx being used in security of the data signal transmitted and received through a Ud interface, the key KASME1 being managed only by the mobile management node MME and a mobile station UE#1, the key KASME2 being managed only by the mobile management node MME and a mobile station UE#2; a step in which the mobile management node MME transmits the key Kx to the mobile station UE#1 and the mobile station UE#2; and a step in which the mobile station UE#1 and the mobile station UE#2 transmit and receive the data signal through the Ud interface using the key K.
摘要:
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.
