JP2000134656A - Portable radio system for private branch - Google Patents

Abstract

PROBLEM TO BE SOLVED: To connect a communication channel by an owner number and to communicate with a desired opposite party at all times even when the owner of specified portable radio for a private branch is changed by adding a mechanism for converting the owner number to a number imparted to the portable radio equipment for the private branch to an exchange. SOLUTION: The owner number of the owner carrying the radio 9 inputted by an input operation from the portable radio 9 for the private branch is stored in a data base 10 inside the exchange 6 corresponding to the radio number of the input radio 9 as a number collation table. In the case the owner number is specified and the call is originated from the portable radio 9 for the private branch, the number collation table is referred to, the radio number pertinent to the owner number is read and the calling is started to the radio of the radio number.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for managing a call of a portable radio by using an owner number held by an owner who carries and uses a portable radio for premises.

[0002]

2. Description of the Related Art In a conventional portable radio system for premises,
A unique number is assigned to each portable wireless device, and when calling a portable wireless device, the calling side dials the number of the portable wireless device to be called and calls the other wireless device to establish a call line. Connected.

[0003]

As described above, conventionally, since the wireless device is dialed using the number assigned to the private mobile wireless device, the wireless device held by the other party who wants to talk is naturally held. You have to know the number. In addition, every time the owner of the indoor portable wireless device changes, it is necessary to recognize which indoor portable wireless device has who.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a first aspect of the present invention is directed to a radio apparatus comprising a switchboard, a radio base station, and a portable radio for premises, and provided to a radio main body. In a portable radio system for premises, which uses a number to make a call between radios via an exchange and a radio base station, the owner of the radio carrying the radio input by an input operation from the mobile radio for premises Means for storing the owner's number of the subscriber in the number comparison table in the exchange in association with the radio number of the input radio, and transmitting a call by designating the owner number from the private mobile radio. Means for reading a wireless device number corresponding to the owner number by referring to the number comparison table and initiating a call to the wireless device of the wireless device number. Note that an ISDN exchange is used as the exchange.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a private portable radio used in the private portable radio system according to the present invention. In the figure, reference numeral 9 denotes a private mobile radio, which comprises a CPU 1, a serial EEPROM 2, a radio module 3, a display 4, a keyboard 5, and the like. The owner who carries and uses the wireless device 9
The user inputs a predetermined owner number from the keyboard 5. Then, the number is serial EE once
Stored in PROM2. The wireless device 9 is registered with a private mobile wireless device number, and the number and the owner number are naturally different from each other.

FIG. 2 is a block diagram showing the configuration of a private mobile radio system according to the present invention. In the figure, 6
Is an ISDN exchange, which is connected to a wireless base station 8 via a wired ISDN line 7. 10 is IS
This is a database provided in the DN switch 6, and stores a number comparison table which is a feature of the present invention. When a private mobile radio 9 is newly entered into the management area of the base station 8, the private mobile radio number registered in the private mobile radio 9 and the registered owner number are wirelessly transmitted. Receive information.

[0007] Next, the base station sets the private mobile radio number in the calling number information element of the ISDN layer 3 protocol, and sets the owner number in the user / user information element. This information is written and registered in the number comparison table by associating the owner number stored in the database 10 of the ISDN exchange 6 with the private mobile station number. FIG. 3 is an explanatory diagram showing the processing operation of the above-described system. When a line connection request based on the owner number is received from the private mobile radio 14 located in the area of the base station 13, the base station 13 sets the owner number in the called number information element and connects to the ISDN exchange 11. Make a request.

At this time, the ISDN exchange 11 analyzes the number, and if it is the owner number, sets the local portable radio number corresponding to the owner number in the called number information element and calls the call registered in the database 15 of the exchange 11. A connection request is issued to the base station 16 based on the location information of the premises mobile radio device 17 of the partner. As a result, the base station 16 calls the in-plant portable wireless device 17 located in the self-management area, so that the wireless device 14 and the wireless device 17 are connected.

As described above, according to the present invention, a mechanism for converting the owner's name into a number assigned to the private mobile radio is added to the exchange. The number is converted into a number assigned to the wireless device, and the telephone line is connected to the target party. As a result, even if the owner of a specific in-house portable radio device changes, if the telephone line is connected with the owner number, it is possible to always talk with the desired party.

[0010]

As described above, according to the present invention, even if the owner of a specific private mobile radio device is changed, if the telephone line is connected by the owner number, the user always talks with the target party. It becomes possible. As a result, the user is released from troublesome wireless device number management.
