The time of passage through a station's service area can now be read externally.

[0013]

[Embodiment] FIG. 2 is a block diagram of the first and second embodiments of the present invention, FIG. 3 is a block diagram of another embodiment of the present invention, and FIG. 4 is a block diagram of still another embodiment of the present invention. It is.

[0014] Here, CPU 151, memory 152
is a component of the information processing/storage unit 15, interface 2
1 is a component of the interface means 2; The operations in FIGS. 2 to 4 will be described below. Since the parts surrounded by dotted lines in FIG. 2 have the same configuration and the same function, the left part will be described.

First, in FIG. 2, each radio base station (hereinafter abbreviated as BS) sequentially and periodically transmits radio waves using a control channel. Furthermore, all mobile phone terminals (hereinafter abbreviated as PS) are assigned a unique individual telephone number (PID).

[0016] Now, PS 12 in mobile phone system A1
uses the control channel to transmit the PID and, for example, the call request to the BS with the highest signal level (e.g., B
S 11 ). Therefore, B.S.
11 sends information that PS 12 is in its service area, ie, location information, to line control device (CONT) 14 via exchange (BX) 13 .

[0017] The line control device 14 is a mobile phone system A1.
By registering location information that indicates which mobile phone terminal is in which service area within the PS, the operating status of the PS, billing information, etc. are managed.

The line control device 14 also sends the registered location information to the CPU 151, which manages the entire network. Location information from another mobile phone system A2, etc. is also input to the CPU, but this location information is stored in the memory 152 in comparison with the PID.

[0019] As a result, the line control device
When notified from the exchange that there has been a call to PS 12 , the PS 12 can be called via the wireless base station 12 using the registered location information.

[0020] Moreover, the PS 12 is a mobile phone system A.
When talking to PS 32 located at PS 2, line control device 14
Since PS 32 information is not stored in the registered location information, it reads the PS 32 location information from the memory 152 and knows that it is in the mobile phone system A2, so it connects the exchange 13, the public network, the exchange 33, PS 12 via line control device 34 and BS 31
and PS32. This allows PS 12
can call PS 32.

In other words, regardless of whether the PS is in the service area of any radio base station, it can communicate with other telephone terminals by performing the necessary line switching at the corresponding radio base station and exchange.

Now, as mentioned above, since the memory 152 stores the current location information of the service area of the mobile phone terminal within the network in comparison with the PID, the interface 21 and the telephone A personal computer 36 is connected via a line 35. Note that the interface 21 has a function of converting the input/output conditions of the personal computer and the read conditions of the memory so that they match.

In the first embodiment of the present invention, the current position information stored in the memory 152 from the personal computer is transferred to the PID.
It can be read out in comparison to . In the second embodiment of the present invention, in addition to the current location information, the memory 152 stores time-series location information and time of passage through the service area of a specific wireless base station. Then, this position storage information is read out from the above-mentioned personal computer. This allows P.S.
You can find out the direction of movement, etc.

Here, the position information of the specific service area is stored in advance in a register (not shown) in the information processing/storage unit 15, and the specific PI read out from the memory 152 is stored in advance.
The comparison/detection section 153 compares and monitors the match/mismatch between the location storage information of the PS of D and the location information of the specific service area.

When the comparison detection section detects a match, it sends a match detection signal to the exchange via the line control device 14, and the exchange detects this match detection signal and automatically sends a designated dial pulse. It is possible to send a message to a pre-requested telephone terminal via a public network to notify that a PS with a specific PID has entered a specific service area.

[0026] Furthermore, by using the above-mentioned coincidence detection signal, for example, a recorder (not shown) in the exchange is operated, and the recorded message is automatically sent to the above-mentioned pre-requested telephone terminal. becomes possible.

Next, FIG. 3 shows a system in which a mobile telephone system is provided with a passage management function by making the service area narrow and separating it from other service areas. Here, in order to realize a specific service area isolated from the above service area, it can be realized by the following method. That is, ■ Place the wireless base station in an electromagnetically shielded area. ■ Use an antenna with a directional characteristic of a specified width. ■ Lowering the transmission power of a wireless base station to a predetermined amount or less than the transmission power of other wireless base stations.

That is, by using the above method, a service area with a narrow width can be realized. Now, as shown in Figure 3, it is isolated in a corridor 43, and there are BS41 and BS42 inside.
A narrow specific service area S41,
Two S42s are provided adjacently. Note that the BS is connected to a line control device and an exchange as in FIG. 2.

Now, as shown in FIG. 3, when a person with a PS enters the isolated specific service area S41 (hereinafter abbreviated as service area S41), he or she enters a password and a number indicating permission to pass through the PS. input on the keyboard. As a result, the location registration signal, password, and PID that were entered in S41 from the PS are transmitted using, for example, a control channel.

BS 41 is a location registration signal from the PS,
Receives the PIN and PID and sends them to the line control device 4.
Send to 5. The line control device is a PS with a specific PID.
Entering the service area S41 is registered together with the time.

[0031] When the PS passes through the service area S41 and moves to the service area S42, the PS sends a notification that it has entered the service area S42 to the line control device via the BS42, so the line control device confirms that the PS is serving the service area S42. Entering area S42 is registered together with the time.

[0032] As a result, the direction determination function within the line control device determines whether the PS is in the service area S41 based on the change in the registered position.
It is determined that the vehicle is moving to the service area S42. In addition, the service area for the direction judgment function is S41 → S
If it changes to 51, move to the right in the hallway and go to S51 →
There is a criterion for determining that if the state changes to S41, it will move to the left, and the determination is made based on this criterion.

Furthermore, when passing through the service areas S41 and S42, (1) the PID of the PS is read, and it is determined whether or not the PID is registered by comparing it with a pre-existing registration list. ■ Read the PID of the PS and the PIN entered in the PS, and select the PI from the PID and PIN target list.
Determine whether D and the PIN number match.

[0034] At this time, if the registration has been completed or they match, a pass permission signal is sent to the PS, and the PS that has received the pass permission displays an indication that the pass permission has been received. People nearby can view it.

[0035] Accordingly, the entrance/exit 44 located at the passing point of the service area is opened/closed depending on whether the display is displayed or not. Furthermore, FIG. 4 shows isolated specific service areas S52, S5
General service area S51, which is not isolated before and after 3.
S54 is provided. Then, BS51 to 54 placed in each service area
are connected to the line control device 55, respectively.

Now, the PS heads to the service area S52 while talking to the other party via the BS 51 in the service area S51, and enters the isolated specific service area S.
Enter 52. This switches from BS51 to BS52.

The line control device detects the above-mentioned service area switching, sends a line hold signal to the exchange from its internal line hold/release function, and sends a message "temporarily disconnect the line" recorded in advance on a recorder (not shown). So just wait.”
A message is sent to the PS and the other party, and the line is put on hold.

Thereafter, when the line control device detects that the PS has passed through the isolated service areas S52 and S53 and entered the service area S54, it sends a hold release signal to the exchange from the line hold/release function described above. Send. Therefore, the exchange releases the held line, so the PS
and the other party starts talking again.

That is, for example, positional information indicating which service area a mobile phone terminal is in can be retrieved from an external personal computer. In addition, we have established isolated specific service areas.
Passage management can be performed using location information.

[0040]

As described above in detail, the present invention has the advantage that, for example, positional information on which service area a mobile phone terminal is located can be retrieved from an external personal computer. Another advantage is that it is possible to establish isolated specific service areas and manage transit using location information.
