Description

Description: TECHNICAL FIELD The present invention relates to a location registration method from a mobile terminal when there are a plurality of call areas in one-way call communication, so-called paging service.

(Prior Art) Conventionally, in paging communication in which a mobile terminal does not have a wireless transmission function, location registration is not performed, and in order to call a mobile terminal that does not know which call area it is, a call is made using a plurality of call areas.

(Problems to be Solved by the Invention) However, making a call even in a call area where a mobile terminal does not exist uses a radio channel ineffectively, and is a waste of precious radio frequency.

SUMMARY OF THE INVENTION It is an object of the present invention to prevent the invalid call by performing location registration from the mobile terminal and making a call only in the call area where the mobile terminal exists when moving to a new call area.

(Means for Solving the Problems) A feature of the present invention for achieving the above object is to provide a radio control station accessible from a general telephone network, a radio base station connected to the radio control station, and a radio base station provided for each call area. In a paging communication location registration system having a mobile terminal connected to a radio base station by a radio line, a radio control station stores a call area code where the mobile terminal exists for each number, and the mobile terminal accesses the radio control station. The base station stores the number, the mobile terminal number of the own station, and the call area code, the radio base station transmits the call area code, and the mobile terminal receiving the radio wave of the radio base station having the strongest electric field, When it is recognized that the call area has been moved, the fact is displayed on the mobile terminal, and the mobile terminal is connected to the general telephone network by acoustic coupling, electric coupling or magnetic coupling, and automatically, In the paging communication position registration system, the stored radio control station access number, mobile terminal number, and newly received call area code are transmitted to the radio control station, and the radio control station updates the stored call area code. .

(Operation) In the present invention, a code indicating the call area is transmitted from the radio base station in the call area, and the mobile terminal receives and identifies the area code, a function of displaying and indicating a new call area, A function to automatically transmit the radio control station access number, call area code, and own mobile terminal number is added, and these data are transmitted from the general telephone network to the radio control station, and the radio control station data corresponds to the mobile terminal number. The call area code where the mobile terminal exists is stored. A call of a mobile terminal is made only in the call area where the mobile terminal exists. Therefore, the object of the invention described above is achieved.

(Embodiment) FIG. 1 shows one embodiment of the present invention, wherein 101 and 102 are radio base stations, 103 radio control stations, 104 is a switching center of a general telephone network, and 10
5 is a home memory for storing a call area where the mobile terminal exists, 106 is a mobile terminal, 107 is a telephone, and 108 and 109 are different call areas.

08 is an operation unit.

FIG. 3 shows an example of a signal frame format of a radio channel transmitted from each radio base station, wherein 301 and 303 transmit synchronization pulses, and 302 and 304 transmit a call area code. FIG. 4 is a configuration example of the memory 204 in FIG. 2, where 401 is a control station access number, 402 is a mobile terminal number, and 40
3 stores a call area code.

In FIG. 1, when the mobile terminal 106 is in the paging area 108 at first, the code of the paging area 108 is stored in the home memory of the control station 103 as the paging area code of the mobile terminal 106. A signal having the format shown in FIG. 3 is transmitted from the base stations 101 and 102, and a code indicating the call area 108 is output from the base station 101 to 302 and 304, and a code indicating the call area 109 is output from the base station 102. Has been sent. When there is an incoming call to the mobile terminal 106, the control station 103 searches the home memory 105 and finds that the call area where the mobile terminal 106 exists is 10
Knowing that it is 8, the call is made in the call area 108. The base station constantly transmits radio waves, and FIG. 5 shows an operation flow when the mobile terminal 106 moves from the call area 108 to the call area 109. In the mobile terminal 106, the electric field strength of the radio wave from the base station 101 decreases. The mobile terminal 106
When the control unit 203 shown in the figure detects a decrease in the electric field strength for a certain period of time (502), the wireless receiving unit 202 searches for another wireless channel with a strong wireless electric field strength (504). In the case of FIG. 1, since it is known that the electric field strength of the wireless channel transmitted from the base station 102 is strong (506), the wireless channel is selected and received (508). The control unit 203 controls the base station 102
Receives the code (302 or 304 in FIG. 3) of the call area 109 of the signal transmitted from the server (510), and compares the code with the contents of the memory 403 in FIG. 4 (512). In this case, since the code of the call area 108 is already stored in 403, the code is different from the code of the received call area 109, so the control unit 203 knows that it has moved to a new call area, and The code is changed to the calling area 109 and a tone is transmitted from the sounding section 207 to the display section 205.
Is displayed to perform location registration (514). The mobile terminal holder who knows this goes to the nearby general telephone 107, picks up the handset of the telephone, confirms the dial tone, connects the speaker 206 of the mobile terminal to the mouthpiece, and operates the operation unit 208. Press the send button at (516). The control unit 203, which knows that the send button has been pressed,
Among them, the control station access number 401 is read out and transmitted from the speaker unit 206 as a push-tone signal (51).
8). The control station access number may be in the form of an OABCDEFGHJ toll telephone number or a 1XY special number format. In any case, when the line extends to the control station 103, the control station 103 sends out a talk or a second dial tone. The mobile terminal owner who heard this,
When the send button 208 is pressed (520), the mobile terminal number of 402 and the call area number of 403 are sent from the speaker unit 206 to the control station 103 as a touch-tone signal (522), and the control unit 2
03 stores the new call area number in 403 (524).

The mobile terminal number may include a password as tampering prevention. The control station that has received these signals stores the code of the call area 109 in the home memory of the mobile terminal 106 that has received the home memory 105 index. In this state, if there is an incoming call to the mobile terminal 106, the control station 103 searches the home memory 105 to find out that the call area where the mobile terminal 106 exists is 109, and the moved call area 109 Can be called.

In the above description, a general telephone was used, and the mobile terminal was connected by acoustic coupling, and a necessary signal was transmitted as a touch-tone signal.
It may have an electrical connection or a magnetic connection. In that case, it is possible to make the speaker unit 206 in FIG. 2 an interface capable of magnetic coupling or electrical connection.

(Effects of the Invention) As described above, the following effects can be obtained by using the present invention.

The paging area where the mobile terminal is located is registered in the control station, and the paging is performed only with the paging area, so that the radio frequency can be effectively used.

A code indicating the call area is transmitted from the radio base station, and since the mobile terminal stores the call area code in which the mobile terminal is present, the mobile terminal automatically identifies whether the mobile terminal has arrived at a new call area. It is possible.

The mobile terminal has a control station access number, a mobile terminal number,
The call area code is stored, and the mobile terminal
