The schedule of the slave unit locus data can be set in advance from the input means of the PC (2). The parent device-fixed telephone conversion table is stored in the parent device 20.
Can be stored. FIG. 10 shows a sequence diagram between the PBX and the PC, and FIG. 11 shows the contents of text in the sequence.

Referring to FIG. 2, description will be made on the assumption that the PBX 1 (1) receives, as a starting point, the position detection of the slave unit by the detection means of the master unit of the cordless telephone system.

First, when a position is detected by the detecting means, a reception position update is started (S20). PBX1
(1) shows a slave unit management table of the master unit as a management target slave unit with respect to the master unit that has received the radio wave of the slave unit, and a PBX1
The information is registered in the parent device and the child device management table in (1) (S21), and the notification unit notifies the PC (2) that the position of the child device has been detected (S22). The notification content is shown in Fig. 1.
As shown in FIG. 1, the location update notification text DRF (T1)
, The master device ID number, the slave device ID number, the direction information, and the induced voltage value are transmitted. Upon receiving the text, the analysis processing means of the PC (2) starts the processing flow as data reception (S100). PC (2) is PC
The distance is obtained from the induced voltage → distance conversion numerical table created in (2) (S101), and it is determined whether the distance between the parent device and the child device is equal to or more than a predetermined distance (S102). This determination is for preventing an unclear call, and when the distance is longer than a predetermined distance, processing is performed to delete the registration because the call becomes unclear. However, the determination processing (S102) Need not be performed. The induced voltage-to-distance conversion numerical table has several patterns, such as outdoor fine weather, rainy weather, and indoors, which are external conditions for cordless installation, and the predetermined distance can be set to an arbitrary distance by data. When the distance is equal to or longer than the predetermined distance, the PC (2) issues a data deletion request as shown in FIG.
As shown in FIG. 1, the data deletion request text DCL is P
The data is transmitted to the BX (S103), and processing for excluding the child device from the parent device →→ child device conversion table shown in FIG. 4 in the PC (2) is performed (S105). There is an effect of immediately regulating the data by changing data such as removing a parent device whose communication level between the parent device and the child device is remarkably reduced from the PC, or excluding a switching device of the child device in which communication is disabled.

When notified from PC (2), P
The BX deletes the data (S23), and deletes the child device from the management target of the parent device (S24). In this processing, the terminal that may make the communication between the parent device and the child device unclear is positively removed.

In (S102), if the distance is within the predetermined distance, the latest position of the data received to target the child device in the parent device-> child device conversion table shown in FIG. Set information and time (S104) (S10)
6). Further, the passing parent device ID and the time are set as the actual data of the child device locus data shown in FIG. 4 (S10).
7). The slave unit locus data may further indicate the distance and the direction from the master unit. PC (2) based on the parent device ← → child device conversion table and child device trajectory data
Can display the position of the slave unit. This will be described later with reference to FIG. The PC (2) analyzes the position of the slave (S108). As the analysis, for example, the case where the position of the slave unit is located at the outermost circle in the permissible range in the radio range of the master unit whose position has been detected or at the exit in the building is analyzed. The content to be analyzed can be determined in advance in the PC (2). As a result of the analysis, if it is located at the outermost circle of the permissible range in the radio range of the parent device, the corresponding parent device identification number, child device identification number, child device telephone Number and talkie N
o. Is sent to notify the talkie connection (S110).
The PBX notified of the talkie connection makes the talkie hear the talkie at the time of calling and answering the slave unit so as to connect the talkie to the slave unit (S27) (S28). For the talkie, for example, an announcement notifying that the user is out of service is set in advance. (S
In the analysis at 108), the PC (2) analyzes so as to use the detection system when the position of the master unit installed at the entrance of the specific place or the like is detected. The parent device installed at the entrance of a specific place or the like is registered in advance so as to be linked with the detection system. In this case, the master unit identification number, the slave unit identification number, the slave unit telephone number, and the VMS number are transmitted as the VMS connection request text (S109), and the received PBX is transmitted.
Starts a processing flow for connecting to the VMS (S25),
The slave unit identification number and the slave unit telephone number are notified to the VMS (7), and a verification request is issued (S26). VMS received
(7) makes a call via the VMS-LINE between the VMS and the PBX to call the slave unit. After the call, the VMS asks a predetermined number of n questions, answers by PB-KEY or voice, and if the collation result is correct, notifies BA (10) to open the automatic door of the specific place. If illegal, the BA is notified as an abnormal intruder.

As described above, the position of the slave unit can be detected, and by analyzing the position, other services can be used.

In the above embodiment, the case where the information is transmitted from the PBX as needed is described. However, the PC further includes transmission request means for requesting the PBX to transmit the position information, and the PBX notification means. May transmit position information in response to a transmission request from the transmission request unit. As shown in FIG. 3, when an instruction is given from the input means or the like, the data is updated (S121), and a request text number is added to the transmission request text DTQ to notify the PBX (S122). Upon receiving the transmission request, the PBX detects the position of the child device from the detection means of the parent device and notifies the PC (S22 shown in FIG. 2). As the transmission request, the identification number of the specific slave unit may be added to request the detection of the position information of the specific slave unit, or the detection request of the position information of all the slave units may be requested. The data is received by the PC (S100),
Thereafter, processing is performed according to the processing flow shown in FIG.

Other applications will be described with reference to the processing flow shown in FIG.

A description will be given of a corresponding application in a case where a slave unit is called during a talkie connection or a VMS connection and a busy or no response is encountered. When the PBX encounters a busy / no response (S31), the PBX adds the base unit identification number to the fixed telephone request text FTQ and notifies the PC (S32). Alternatively, a slave unit identification number may be added. The PC receiving the fixed telephone request performs busy / non-answer processing (S11).
4). The PC (2) refers to the master-fixed-telephone conversion table in FIG. 4 and extracts the nearby phone number of the management master unit ID closest to the called slave unit (S115).
X, and sends a fixed telephone number notification text FTA to X (S1).
16). The received PBX calls the fixed telephone according to the fixed telephone number, so that if a nearby mobile phone of the slave unit receives the fixed telephone, the mobile phone can easily receive the general transfer service. In addition, since the transfer from the mobile terminal to the fixed wired telephone becomes possible, the block rate of the caller who makes the telephone call can be reduced, and the service between the mobile terminal and the fixed terminal can be provided. is there.

Next, an application (S111) corresponding to a case where the slave unit becomes unusable will be described. First, PC
(2) detects a case where the position re-registration of the slave unit has not been performed for a predetermined time (S112). When the difference between the update time and the current time in the conversion table between the parent device and the child device in FIG. As in the process of S105),
The data in the PC is deleted, and the data deletion request text DCL is sent to the PBX (S113). The PBX that has received the data deletion request activates the flow of (S23) shown in FIG. In this process, the relationship between the parent and the child can be released at an early stage, so that if the data is left, it is possible to prevent the calling and the calling from being disabled.

Next, an application (S117) enabled by detecting and accumulating the position information of the slave unit will be described. This process can be started when the latest data is recorded in the slave unit locus data shown in FIG. 4 in (S107) in FIG. In this case, the predetermined trajectory data of the slave unit and the actual trajectory data are collated (S1).
18) If not, a warning display is output on the display screen of the PC (2) (S119). At the same time, an automatic call request text ACL is issued to the PBX (S120). The received PBX activates the automatic call (S29), and the PC
(2) Automatically make an outgoing call from a landline phone (9) near the installation (S30), deviate from a predetermined route, or ask for a delay in action, so that it is possible to respond immediately to an unexpected abnormal situation. Useful for.

Next, examples of screens displayed on the screen of the PC (2) based on the recorded data shown in FIG. 4 are shown in FIGS.
This will be described with reference to FIG.

FIG. 5 shows display screens G1 to G4. FIG. 6 and FIG. 7 are examples of an initial screen when the whole using a cordless telephone (child device) is a building or the like. FIG.
FIG. 9 and FIG. 9 are examples in which the information is displayed based on the locus information of the child device.

In FIG. 5, an initial screen G1 is a screen showing a layout of more master units. Each master unit is indicated by □, and the radio range of the master unit is indicated by a dotted circle. I, j, and k written next to the master unit indicate the number of slave units to be managed. An instruction is received from the keyboard of the input means, and the display screen shifts from a display screen G1 to a display screen G2, and the telephone number of the child device managed by each parent device and the owner name (referred to as text) registered in advance for the telephone number are displayed. I do. The display screen of G2 is G
It can be displayed by a technique such as partial enlargement of four divisions for one. If you want to shift to the detailed display,
→ The instruction to move to G3 is received by the keyboard, and the direction and distance of the child device with respect to one parent device are displayed in the information. Thereby, the correct position of the slave unit can be displayed, and the information of the slave unit with respect to the master unit is displayed by combining the switching device information and the information set by the PC, thereby improving the recognition of the slave unit. . In this example, the transition screen is G1 → G2 → G3. However, if space on the screen is allowed, the display information of G3 can be used as the display information on the initial screen. Also, it may be displayed on a multi-screen. If a search key input shown in G4 is prepared on each screen, it is also possible to display the search result by brightening only the target handset after the search key input. By facilitating the conversion between the entire screen and the detailed screen, there is an effect that the operation progresses smoothly. Further, only predetermined information can be picked up from a large amount of information, which has an effect of facilitating selection of information display. Note that the coordinate position and the installation location for the parent device ID are registered in the PC (2) in advance.

As another display example, as shown in FIG. 6, a base unit and a radio wave state in a plan view from one direction of a building may be shown. Further, as shown in FIG. 7, the building may be represented three-dimensionally and the radio wave range may be represented not spherically but spherically. 6 and 7, the information of the slave unit can be displayed.

FIGS. 8 and 9 show other display examples.
As shown in (1), the locus information of the slave unit can be shown in the figure together with the passing position and the passing time. In FIG. 8 and FIG. 9, xxx indicates a slave phone number, and △△△△ indicates a text. The planned route and the actual route are displayed from the table shown in FIG. 4, and a warning message is displayed when a mismatch is detected in the collation check processing of (S118) shown in FIG. In FIG. 8, as shown on the left side, it is displayed so as to emphasize the mismatching point by encircling it with a dashed line, and on the right side, a floor plan where the master unit that has detected the abnormal point is installed is displayed. Display and highlight the radio range and the location of the handset. In the case of a color screen, the color may be changed and displayed. When receiving an instruction to call the slave unit when an abnormality is detected, the instruction is received, for example, by the function key F1 of the input unit and shown in FIG. 2 (S12).
0).

In FIG. 9, the actual route of the slave unit is displayed, and the movement status is displayed on the right side. The movement status can be used for collation of the operator by setting the dotted route as the scheduled route and the solid route as the actual route.

As described above, by changing the movement of the slave unit from the point display to the continuous display, there is an effect that the movement direction can be estimated on the screen display. In addition, by comparing the actual trajectory data with the planned trajectory data and using the result of the disagreement,
It is possible to detect a movement error and an unexpected event occurrence, automate the immediate response, and use the system as a monitoring system.

Next, detection by the detection means of the master unit will be described with reference to FIGS. FIG. 12 is a block diagram of a master unit with a directional antenna, and FIG. 13 is an external view of the master unit with a directional antenna.

The control unit 203 receives a signal from the slave unit at the receiving unit 202, obtains the direction of the slave unit based on the direction of the received directional antenna, detects an induced voltage value from the received signal, and sends the value to the exchange. Information is transmitted using PBX using the ISDN-D channel.
Can be notified. When a normal call is made, the control unit 203 detects the calling of the call, stops driving of the directional antenna, and fixes the directional antenna in the direction of the slave unit to talk. Thus, the position of the slave unit is detected.

As described above, according to the present invention, the constantly changing position information of the slave unit in the PBX is accumulated in the PC,
By processing, it can be displayed on the screen of the PC. The user can grasp the status of the slave unit at a glance by looking at the display screen, and can detect an abnormality and use it as a monitoring terminal. The PC can analyze based on the data received from the PBX side and hold appropriate data.

Further, by processing the instantaneous data of the mobile terminal exchange in the PC and reflecting the data on the mobile terminal exchange, the accuracy of the data in the mobile terminal exchange can be improved and the display function on the PC side can be achieved. Various application services can be performed using.

The processing of the data held by the exchange is processed by the PC which is the external information processing device, and the exchange transmits to the PC when the position is detected, so that the PC can always process with the latest information. This has the effect of avoiding recognition errors due to information. Further, there is an effect that a transmission request can be made from the PC and data communication between the exchange and the PC is optimized.
Furthermore, since exchange information other than exchanges connected to the PC can be collected and processed via a common line, a screen display as an exchange network is possible, and a wide range of exchanges having a plurality of exchanges without depending on the performance of one exchange. It can operate for moving areas. Also in this case, the number of display devices is one and there is an effect that the display device can be unified. Also, the information of the parent device concentrator connected as the location terminal of the exchange connected to the PC is stored in the ISDN.
By collecting information using the D channel of the line, there is an effect that it is not necessary to connect another signal line.

Further, since the distance and the direction from the master unit can be known more accurately, there is an effect of increasing the accuracy of the position information display. Since the detection by a specific master unit can be used for security, there is an effect that the slave unit can be used not only as a telephone terminal but also as a security system terminal.
