PCT No. PCT/JP96/00241 Sec. 371 Date Sep. 27, 1996 Sec. 102(e) Date Sep. 27, 1996 PCT Filed Feb. 6, 1996 PCT Pub. No. WO96/25014 PCT Pub. Date Aug. 15, 1996A mobile communications system including a plurality of communications networks, each of which has one location register (a home location register or gate location register) and one or more visitor registers. Each of the visitor registers is located in each one of visiting areas for storing information about a communication terminal. The location register stores the number of the visitor register of the visiting area in which the communication terminal is present, and the information about the communication terminal. When the communication terminal moves between the communications networks, the information about the communication terminal is transferred between the location registers. When the communication terminal moves between the visiting areas in the same communications network, the information about the communication terminal is provided from the location register to the visitor register. When the communication terminal moves within the same visiting area, the information about the communication terminal can be obtained from the visitor register. This makes it possible to reduce the traffic on the common control line between the communications networks and in the communications network.
