Abstract: A mobile communication system comprises: at least one terminal; a source base station to which the terminal is connected before movement of the terminal; a target base station to which the terminal is connected after the movement; a gateway device that connects the source base station and the target base station to a core network; and a core network node provided in the core network, wherein: the gateway device determines by itself, or makes query to the core network node to determine whether or not to preferentially treat the terminal by the target base station when the terminal moves from the source base station to the target base station; and the gateway device notifies to the target base station preferential information indicative of whether or not to preferentially treat the terminal by the target base station.

Abstract: A mobile communication system including: a terminal, a movement-origin base station to which the terminal connects before movement of the terminal; a movement-destination base station to which the terminal connects after movement of the terminal; and a higher-order apparatus that has the movement-origin base station and the movement-destination base station under its control. Control information for voice encoding is set in advance in the movement-origin base station and the movement-destination base station, the movement-origin base station includes the control information of its own station in a first message and transmits the first message to the higher-order apparatus, and the higher-order apparatus includes the control information of the movement-origin base station in a second message and transmits the second message to the movement-destination base station.

Abstract: A wireless communication system includes a wireless base station FAP2 which communicates with a mobile communication terminal UE1; a core network apparatus CN4 which is a higher-level apparatus of the wireless base station; and a femto wireless base station gateway GW3 which relays between the FAP2 and the core network apparatus CN4. The wireless base station FAP2 includes a determination unit 21a which determines whether to stop voice call reception processing or voice call transmission processing with reference to determination information upon detection of a voice call reception to the mobile communication terminal UE1 within a communication service area or a voice call transmission from the mobile communication terminal UE1 within the communication service area in the FAP2; and a signal processing unit 25a which informs a higher-level apparatus of a message including a determination result when the determination unit determines to stop the processing.
