The present invention relates to a Private Branch Exchange (hereinafter referred to as a PBX) system, and in particular, when a called person is in the office but is not in a seat and does not receive an incoming call, the PBX wirelessly calls the caller's personal identification number. The present invention relates to a telephone switching method using a personal identification number call so that the telephone can be switched to an extension telephone where the called party is recognized.

In general, a PBX system installed in a premises such as a public office, a company, or a factory includes a PBX 3 that is in charge of a telephone exchange service and an internal telephone 4 connected to the PBX 3, as shown in FIG. And interworking between the external telephone (1) and the local telephone (4) through the public telephone network (2). In addition, the interconnection between the telephones in the premises is performed.

However, in the conventional PBX system as described above, it is difficult to make a telephone call when the called party is not present when a call is received from the outside or the premises. In other words, if the called person is not in his or her office, the call can only be made if the called person is within a certain range of where the called person can answer the call or if the person who called the call knows where the called person is located. It was. As a result, the area where the callee could receive calls was limited.

The present invention has been made in view of the above circumstances, and an object of the present invention is to call the personal identification number of the called party in PBX wirelessly when the called person is not in the office but not in a seat, the callee's location It is to provide a telephone switching method using a personal identification number call so that the telephone can be quickly switched to a recognized local telephone.

Another object of the present invention is to call the caller in the PBX wirelessly by switching the call to the extension of the called party recognized the personal identification number, the individual who allows the callee to receive the incoming call in the company without restriction of the telephone receiving area It is to provide a telephone switching method using the identification number call.

Telephone switching method using a personal identification number call according to the present invention for achieving the above object is provided in the PBX system having a PBX and a base station with a wireless pager with a personal identification number and a personal identification number recognition means; The first step is to send a ring signal to the extension telephone number received from the outside or the inside of the PBX, and if the corresponding extension telephone is not hooked off within a certain time, the caller's personal identification number is wirelessly called from the PBX. And a third step of connecting the call path from the PBX to the extension telephone when the called party recognizes the personal identification number on an arbitrary extension telephone.

Other objects and advantages of the present invention will become apparent from the description of the embodiments of the present invention with reference to the accompanying drawings.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIGS. 2 and 3.

2 is a diagram showing the configuration of a PBX system that can be applied to the telephone switching method using a personal identification number call according to the present invention, the PBX system is a wireless pager 6, a barcode recognition device is attached with a barcode as the personal identification number Connected to the local telephone (4), the base station (5) for wireless calling, the local telephone (4) and the public telephone network (2) and the base station (5) and the PBX (3) for telephone exchange and wireless calling. Equipped.

3 is a flowchart illustrating a telephone switching method using a personal identification number call according to the present invention, which will be described with reference to FIG.

When a call is received from the housewife through the public telephone network 2 or a call is received from an arbitrary premises phone 4, in step 10, the PBX 3 receives the premises phone number called by the housewife or the premises and step 11 In PBX (3) sends a ring signal to the received extension number. In the twelfth step, the PBX 3 then determines whether the seaside telephone 4 is hooked off.

In step 12, if the corresponding extension telephone 4 is not hooked-off even after a predetermined time elapses, in step 13, the PBX 3 transmits the personal identification number of the called party corresponding to the extension number to the base station (at the time of waiting for call). 5) and the radio base station 5 calls the number. In this case, the personal new number assigned to each individual may be an extension number added to an employee number or a phone number. Subsequently, in step 14, the PBX 3 determines whether the personal identification number of the called party is received. Here, the personal identification number reception is performed by the called party who recognizes the ringing tone and recognizes the personal identification number in the nearby old telephone 4 using the card type pager 6 in which the personal identification number is stored in a barcode or a magnetic bar. It is made by transmitting the personal identification number and its own extension number information recognized by the card type pager 6 in the extension telephone 4 to the PBX 3.

At this time, since the card-type wireless call stem 6 is used only in the premises, it does not have a separate display means and the like. The premises telephone 4 attaches a barcode reader or a card read to recognize a personal identification number. In addition, the card type pager 6 is not provided separately, and the wireless pager can be incorporated into an ID card for use.

In step 14, if the called party's personal identification number is received, the process proceeds to step 15 whereby the PBX 3 switches to the corresponding phone 4 where the personal identification number and the extension number are received, thereby forming a call path. The called party conducts the call (step 16).

On the other hand, if the personal identification number of the callee tape in step 14 is not received even after a certain time has elapsed, the PBX (3) sends a voice message of the 'absent squad' to the caller that the caller cannot make a phone call with the called party. Announce (step 17)

In addition, when the internal telephone 4 is hooked off in step 12, the PBX 3 checks whether a specific button is pressed on the corresponding telephone 4 (step 18). If a specific button of) is not pressed, the call path is connected, so the PBX 3 enters step 16 to allow the caller and the called party to proceed. On the other hand, when a specific button of the sea telephone 4 is pressed in step 18, the PBX 3 sends a call message to the caller, sets the standby mode for the call, and then enters the step 13 by calling. Perform the transition process (Step 19).

As described above, according to the present invention, the PBX system includes a card-type wireless pager in which a personal identification number is in the form of a barcode or a magnetic bar, and an on-site telephone with a barcode reader or a card reader. By calling the called party's personal identification number wirelessly and calling the caller who switches the call to an extension phone that recognizes the personal identification number, the called party can answer the phone without any local restrictions within the company. .

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification but should be defined by the claims.
