These operations are exactly the same as those of the general ISDN terminal shown in FIG. On the other hand, the destination display device 1a that has received the incoming call setting sends the call setting acceptance message to the PBX2.
After sending, the release completion is sent and the incoming call is terminated. At this time, within the destination display device 1, the position display information table 109 is searched by referring to the position number included in the user / user information received in the call setting message, and the position display information corresponding to the position number is selected. Also, the display column table 110 is searched from the MS-No, the position of the destination display column is calculated, and the display RAM 17 of the position corresponding to the calculated position of the destination display column is displayed.
By writing the selected position display information in, the character "attended" in the destination field shown in FIG. 1, for example, is displayed. As described with reference to FIG. 5, in the standby state, the MS 51a periodically receives the broadcast information from the BS, and does not activate the location registration procedure again in the same zone in which the location has already been registered. , When the notification information of the position number different from the position number stored in the MS is received, it is considered that the user has moved to the new zone, and the position registration procedure for updating the in-zone is activated. At time point 2 in FIG. 16, M
It is assumed that the user of S51a carries the MS51a and moves to the conference room in the zone n shown in FIG. 2 by a conference or the like.
At this time, the BS-n in the same zone periodically broadcasts the broadcast information of the position number = n on the BCCH.
At this point, the MS knows that the visited zone has previously moved, and the location registration procedure is activated via the BS and the PBX2
The mobile management function 201 of memorize | stores that MS51a is located in zone n, and subsequent incoming calls to MS51a will be automatically notified to zone n. In conjunction with the location registration procedure, the MS uses the destination display apparatus number of its own group as the destination number (destination number) for the destination display apparatus 1a of its own group, and its own mobile terminal number (MS-no) and location registration procedure. Generate a call setup message in the format shown in FIG. 6A in which the position number of the zone where the
The PBX 2 is requested to make a call, and thereafter, the updated position is displayed in the destination display column of the corresponding name on the destination display device 1a by the same operation sequence as described above.

From the above description, it has been clarified how in the destination display device according to the first and second inventions, the location information indicating the location of the mobile terminal is displayed in the destination display field. The method of displaying the remarks column of the destination display device shown in FIG. 1 will be described below. The destination display is not only the destination, but also the time to return to your seat in the remarks column, the number of times you go out of the office and go to an area not covered by the destination display system, such as the number of the destination, a simple number such as vacation, etc. It would be very effective if the personal schedule could be displayed as an arbitrary message. In the configuration of the mobile terminal shown in FIG. 14, the ROM 2 in which the control program is stored is displayed on the display of the man-machine interface 53 as "IUEO ...".
By displaying the Japanese syllabary and selecting it with the dial keys, the editing function of any message is installed. Alternatively, a frequently used fixed message may be stored in advance and selected, or the message may be edited using the name and telephone number of the other party stored in the telephone directory program. For sending a message from a mobile terminal, when the user of the mobile phone leaves the seat or moves to a conference room, the desired message is edited or selected, and the message is included in the user / user information. By performing an operation for making a call to the destination display device of its own group by the call setting message, an arbitrary message is displayed in the remarks column of the destination display device. Further, when the mobile terminal activates the location registration procedure, the user is caused to sound an alarm or the like before sending the call setup for transmitting the location number to the destination display device of its own group in conjunction with the message. May be prompted.

The destination display device extracts the above message together with the mobile station number and the position number from the user / user information included in the call setup message received from the mobile terminal, and the corresponding name from the mobile station number. The display column is identified, the position information corresponding to the position display information is displayed from the position number in the destination column, and the character information is written in the corresponding position in the display RAM so that the message is displayed in the remarks column.

In the above embodiment, the case of the destination display device using the wall-mounted type destination display panel having a large-sized display element has been described, but this is not limited to the wall-mounted type and has other display elements. It can also be realized in a display device. For example, it is possible to add a line interface such as an ISDN interface to a personal computer as the destination display device and display the destination in a predetermined format on a CRT display or a liquid crystal display by software. Further, the display format of the destination display surface is not limited to the embodiment, and it is needless to say that it can be variously modified.

In the above embodiment, when the position number received from the base station in the broadcast information is different from the position number registered previously in the mobile terminal, the position registration procedure is started for the new base station immediately. , I explained the case of updating the existing zone, but generally, between adjacent zones, measure the electric field strength level of the radio waves from surrounding base stations and register the location with the base station with stronger electric field strength. Become. Therefore, when a person moves between zones on the same floor where there is no obstacle such as a wall in a short time, the position registration procedure is prevented from being unnecessarily activated or the display of the destination display device is unnecessarily updated. Therefore, it detects that it has been in the zone of the base station with a stronger electric field strength for a predetermined time or more continuously, activates the location registration procedure, and transmits the destination information to the destination display device. Good.

In the above embodiment, the destination display is updated by updating the destination of the destination display device after the corresponding mobile terminal moves to the new zone and activates the location registration procedure for the new base station. For example, when the mobile terminal moves to a non-service area where radio waves from the base station do not reach, the destination display remains displaying the old position. To solve this, from the destination management device or destination display device,
It is also possible to call each mobile terminal periodically and delete the destination display field when there is no response.

Furthermore, in the above embodiment, the P
Although the case of the private branch exchange system centering on the BX has been described, this is not limited to the private branch system, and can be applied to a wide area mobile communication service such as a car phone or a cellular phone. In this case, since the area covered by one base station becomes wider, it is not possible to specify the location in detail, so rough location information such as district name is provided as a network service, and detailed location information is provided by the user. If necessary, the user / user information may be transmitted to the destination display device installed in the office by operating the mobile terminal. Further, the communication procedure between the communication network and the mobile terminal, or the destination management device and the destination display device is not limited to the embodiment. Furthermore, the mobile terminal may be, for example, a wireless card or the like.

As described above, according to the present invention, the location zone of the mobile terminal is specified by the location registration procedure for notifying the location zone between the mobile terminal and the network, and the location registration procedure is performed. It is possible to provide a destination display system that automatically displays the destination on the destination display device of the group to which the mobile terminal belongs, based on the known location information of the mobile terminal. Therefore, the user does not have to enter the destination on the destination display panel or delete the destination column when returning to the seat when the user is out of the office and does not have to take the seat. Then, it is possible to automatically display the destination and display an arbitrary message in the remarks column. Furthermore, even when moving from one place to another, the user can display the destinations automatically and in a timely manner without the need for the user to contact each other. To be realized.
