Mobile communication system, originating base station, candidate base station, and mobile terminal

Abstract

A mobile communication system, which changes a communication partner of a mobile terminal from an originating base station to a destination base station, wherein a request message requesting to become a candidate is transmitted to a plurality of candidate base stations, which are potential destination base stations, from the originating base station, a response message responding to the request message is transmitted from the plurality of candidate base stations to the originating base station, and information of the candidate base stations is transmitted from the originating base station to the mobile terminal.

1 . A mobile communication system, which changes a communication partner of a mobile terminal from an originating base station to a destination base station, wherein
 a request message requesting to become a candidate is transmitted to a plurality of candidate base stations, which are potential destination base stations, from the originating base station,   a response message responding to the request message is transmitted from the plurality of candidate base stations to the originating base station, and   information of the candidate base stations is transmitted from the originating base station to the mobile terminal.   
     
     
         2 . The mobile communication system according to  claim 1 , wherein
 the originating base station is an energy saving base station capable of energy saving operation.   
     
     
         3 . The mobile communication system according to  claim 1 , wherein
 the destination base stations are compensating base stations compensating operation of the originating base station.   
     
     
         4 . An originating base station, which changes a communication partner of a mobile terminal from an originating base station to a destination base station, wherein
 a request message requesting to become a candidate is transmitted to a plurality of candidate base stations, which are potential destination base stations,   a response message responding to the request message is received from the plurality of candidate base stations, and   information of the candidate base stations is transmitted to the mobile terminal.   
     
     
         5 . A candidate base station, which is a potential destination base station, in a mobile communication system in which a communication partner of a mobile terminal is changed from an originating base station to the destination base station, wherein
 a request message requesting to become the candidate is received from the originating base station, and   a response message responding to the request message is transmitted to the originating base station.   
     
     
         6 . A mobile terminal in a mobile communication system in which a communication partner of a mobile terminal is changed from an originating base station to the destination base station, wherein
 to a plurality of candidate base stations, which are potential destination base stations, a request message requesting to become the candidate is transmitted from the originating base station,   a response message responding to the request message is transmitted from the plurality of candidate base stations to the originating base station, and   information of the candidate base stations transmitted from the originating base station is received.
