<P>PROBLEM TO BE SOLVED: To enable call connection data to be transmitted/received between a controller and a terminal via a base station to which the destination of a call connection is switched, if the destination of the call connection is switched from a base station which has received a call connection request of the terminal to another base station, with no call connection established yet between the terminal and base stations. <P>SOLUTION: A first base station 1 transmits information for establishing call connections. A second base station 3 has a coverage area which overlaps with a coverage area of the first base station 1. A terminal 5 is connected to the first base station 1 or the second base station 3 for a call. A controller 6 manages the location and movement of the terminal 5. When the first base station 1 receives a call connection request from the terminal 5, it reports to the controller 6 by a handover procedure that the destination of the call connection requested by the terminal 5 is switched to the second base station 3, and notifies the terminal 5 of frequencies for the second base station 3. The terminal 5 makes a call connection to the second base station 3 using the frequencies notified by the first base station 1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
