Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention provides a method for communicating between the calling party and the called mobile station by dialing the same telephone number of the called mobile station, regardless of where the called mobile station is located. This relates to an area-independent mobile communication system that can connect

Background of the Technology In the conventional area-free mobile communications system, when a general telephone calls a mobile device, the call is made from the originating central station RC to the nearest mobile communications exchange, and the nearest mobile communications exchange receives the location information of the mobile device. It accesses and sets up a dedicated mobile communications line to the destination mobile communications exchange, and also transfers billing information determined from the location information of the mobile device to the local exchange LS or toll originating exchange TOS, It was a billing method.

Prior Art and Problems Conventional area-free mobile systems require (1) dedicated lines for mobile communication between mobile communication exchanges, resulting in high costs;

(2) Since billing information is transferred during connection control, there are drawbacks such as long connection delay times.

Purpose of the Invention In order to solve these drawbacks, the present invention provides a system in which the originating exchange uses a control line between exchanges to access movement information of a mobile terminal, and the existing telephone network is used up to the destination mobile communications exchange. The drawings will be described in detail below.

Embodiment of the invention The figure shows an embodiment of the invention, in which 1 is a telephone;
2 is a mobile device, 3 is a subscriber line exchange, 4 is a trunk exchange, 5 is a central control unit, 6 is a register, 7 is a communication line network device, 8 is a common line signal path, 9 is a mobile communication exchange, 10 is a central A control device, 11 a memory, 12 a communication network device, 13, 14, 15 a relay exchange,
16 is a mobile communication exchange, 17 is a common line signal path of a control line, 18 is a central control unit, 19 is a communication network device, and 20 is a radio base station.

When a general subscriber dials the mobile communications service identification number (for example, 030) and the telephone number of the mobile device 2 (for example, "2012345") from the telephone 1, the subscriber line exchange 3 uses the conventional technology to Send the above dialed number to 4. When the central control unit 5 identifies the dialed number "302012345" received by the register 6, it sends the telephone number "2012345" of the mobile device 2 to the mobile communications exchange 9, which has the location information of the mobile device 2, via the common line signal path 8. ” to request the location information of the mobile device 2. Based on the received phone number "2012345" of the mobile device 2, the central control device 10 accesses the memory 11, extracts the location information corresponding to the phone number "2012345" of the mobile device 2, and outputs the common line signal. The location information is sent to the relay exchange 4 via the route 8. Central control device 5
Based on the received location information, the communication path network device 7
The train is set up to the relay exchange 13, and the area where the mobile device is located, which consists of the mobile communication service identification number “30” in the relay exchange hierarchy and the location information of the mobile device 2 (for example, “40”), is set. It sends route information to the mobile communications exchange and a temporary number (for example, 111) given to the mobile device 2.
The transit exchange 13 sets a train to the transit exchange 14 based on the received route information and the temporary number "3040111." Thereafter, trains are similarly set up to the relay exchange 15 and mobile communication exchange 16. Further, the central control unit 5 sends the actual telephone number "2012345" of the mobile device 2 and the corresponding temporary number "111" via the common line signal path 17. The central control unit 18 receives mobile terminals 2 via the common line signal path 17.
The number of the called mobile device is "2012345" based on the telephone number "2012345" and the temporary number "111" and the route information "40111" received via the telephone line at the mobile communications exchange 16 where the mobile device 2 exists. When this is determined, the mobile device 2 is called via the radio base station 20 and a response signal is returned to the relay exchange 4 via the common line signal path 17. The relay exchange 4 is
Upon receiving the response signal, the temporary number "111" given to the mobile device 2 is released.

Although the present embodiment has been described using the common line signal paths 8 and 17, it goes without saying that the control line is not limited to the common line signal paths and can be applied to a control line in general.

Effects of the Invention As explained above, the present invention uses an existing telephone line for the line from the subscriber line exchange to the destination mobile communication exchange. is not necessary and is economical. Furthermore, since there is no need to transfer billing information during connection control, there is an advantage that connection delay time can be reduced.

Claims (1)

[Claims] 1. When a caller of an existing telephone network subscriber dials the telephone number of a mobile device, the caller and the mobile device can travel in and out of the area of the mobile communication exchange that stores the subscriber information of the mobile device at any time. When an incoming call is received to the mobile device in an area-free mobile communication system connecting the mobile device, the originating exchange stores the subscriber information of the mobile device via the control line between the exchanges. The location information of the mobile device is received from the mobile communication exchange in the area where the mobile device is located, a temporary number is assigned to the incoming call, and the temporary number and the actual location of the mobile device are sent to the mobile communication exchange in the area where the mobile device is located. The phone number of the mobile device is sent via the control line, the route information to the mobile communication exchange in the area where the mobile device is located, and the temporary number are sent via the call line of the existing telephone network, and the mobile device A mobile communications exchange in an area where the area exists controls the connection between the caller and the mobile device by extracting the actual telephone number of the mobile device from the temporary number. Communication method.
