Abstract

PURPOSE:To monitor the position of each radiotelephony set through the operation from an external equipment. CONSTITUTION:Connectors 6-9 receive a position registration signal emitting from radiotelephony sets 10-15 and sends the position registration information to a central controller 2 via line controllers 4-5. The central controller 2 registers the position of the radiotelephony sets 10-15 based on the correspondence between the radiotelephony sets 10-15 and the connectors 6-9 and when the radiotelephony sets 10-15 are move to the outside of the registered zone, the position information registered already by a position registration signal received by the connectors 6-9 after the movement is updated. The updated or registered position information of the radiotelephony sets 10-15 is stored in the database 18 of an external computer 17 via an interface bus 16 by an interface controller 3.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of one embodiment of the present invention.

The present embodiment is directed to a wireless telephone 1 of a private MCA.
0 to 15, connecting devices 6 to 9 for accommodating the wireless telephones 10 to 15, line controllers 4 and 5 for controlling the connecting devices 6 to 9, line controllers 4 and 5, and connecting devices 6 to 9. A central control device 2 which can be controlled by the radio telephones 10 to 15 via an external computer 1 connected to the central control device 2
And an interface control device 3 having an interface bus to the central control device 2 via the line control devices 4 and 5 which receive the position registration signals emitted from the radio telephones 10 to 15. First means for transmitting the location information registered in the wireless telephones 10 and 15, and the central control device 2 performing the location registration of the wireless telephones 10 to 15 in correspondence with the wireless telephones 10 to 15 and the connection devices 6 to 9; Is moved out of the registration area, the second means for updating the position information registered by the first means by the position registration signals received by the connected devices 6 to 9 after the movement, and the first and second means The position information of the radio telephones 10 to 15 registered and updated by the means of
Third means for storing in the database 18 of the external computer 17 via the
According to the operation 0, the position information of the wireless telephones 10 to 15 is extracted from the database and displayed on the monitor device 19.

FIG. 2 is a format diagram of the location registration / update information of this embodiment. The location registration / update information of the wireless telephones 10 to 15 transmitted from the interface control device 3 to the external computer 17 via the interface bus 16 is shown. Is a message identifier 21 of the message itself, a message type 22 representing the meaning of the message such as location registration or update, a first information field 23 added as necessary according to the meaning of the message type 22, and a second information field. It comprises a field 24 and third field information 25.

Next, the operation of this embodiment will be described. First, a registration request signal for position registration is emitted from the wireless telephone 10. Since the wireless telephone 10 is in the radio wave arrival zone of the connection device 6, the registration request signal is received by the connection device 6. The connection device 6 that has received the registration request signal reads the logical extension number of the wireless telephone 10 of the transmission source from the registration request signal, and notifies the line control device 4 that there has been a position registration request from the wireless telephone 10 of this logical extension number. To the central controller 2 through

The connection device 6 itself is given a physical extension number in the exchange, and this number is assigned to the central control device 2.
Can be identified. The central control unit 2 receives the logical extension number and the signal of the requesting wireless telephone 10 from the location registration request sent through the line control unit 4 and the connection unit 6.
Both physical extension numbers can be identified.

[0010] Further, the location registration request is stored in its own internal memory corresponding to the logical number, and then sent from the central controller 2 to the interface controller 3 together with the information on both numbers. 16 and converted and edited into a message format.

The message identifier 21 of the message format is a (FF) 16 code indicating the start of the message, and the message type 22 represents a location registration request (A
A) ASC2 code, first information field 23
Indicates that the logical extension number of the wireless telephone 10 is the ASC2 code, the second information field 24 is that the physical extension number of the connection device 6 is the ASC2 code, and the third information field 25 is
Are filled with ASC2 codes, respectively. The edited message is immediately transferred to the database 18 of the external computer 17 via the interface bus 16.

Next, the radiotelephone 10 moves away from the radio wave arrival zone of the connection device 6 whose location has been registered first, and moves to another connection device 9.
In this case, the central control unit 2 receives the logical extension number and the signal from the location registration request of the wireless telephone 10 sent through the line control circuit 5 as in the first location registration. Identify both physical extensions of device 9.

The central controller 2 refers to its own internal memory corresponding to the logical extension number, finds out that the position of the radio telephone 10 has been registered, judges that this request is not a registration but a position update, and The content of the corresponding internal memory is updated with the new physical extension number of the connection device 9 and the connection device 6 is updated.
Is added to the location registration request and sent to the interface control device 3.

The interface control device 3 knows from the additional information of the old physical extension number that the location update is to be performed instead of the location registration, and converts and edits the information into a location update message format. The data is transferred to the database 18 of the computer 17.
The content of this message format differs from the previous one in that the message type 22 indicates a location update request (B
B) ASC2 code, the second information field 23 becomes the ASC2 code of the new physical extension number of the connection device 9,
The third information field 24 is an ASC2 code of the old physical extension code of the connection device 6. The external computer 17 that has received this information immediately updates the database 18 in the same manner as the central control device 2 updates its own internal memory.

In this embodiment, the radio telephone 10 has been described. However, the position registration and the position update of the other radio telephones 11 to 15 and the movement of the radio telephones 10 to 15 from the connection devices 6 to 9 to the outside of the radio wave arrival zone can be performed. The same applies to position deletion due to battery exhaustion, etc., and the description is omitted.

In this way, the system supervisor retrieves the position information of the radio telephones 10 to 15 registered and updated in the database 18 in real time to the monitor device 19 by operating the terminal device 20 to monitor and follow up. Can be performed freely.

[0017]

As described above, according to the present invention, the position registration and update information of the accommodated wireless telephone are transmitted to the computer of the external device, so that the position of each wireless telephone can be monitored by an operation from the external device. It has the effect of being able to.
