Description

Multi-line service method using virtual port in private exchange

The present invention relates to a multiline service method of a private exchange, and more particularly, to a multiline service method using a virtual port in a private exchange.

In general, a multi-line service provides a call service by assigning several telephone numbers to a single telephone in a private exchange. In order to receive the multi-line service, the telephone is provided with a plurality of telephone number function keys to which a telephone number is assigned, and different telephone numbers are assigned to the telephone number keys.

In order to provide such a multi-line service, a unique telephone number must be assigned to each of a plurality of real physical ports, and a software link between telephones connected to each physical port must be formed. Therefore, in the case of sharing telephone numbers between telephones in a private exchange, the shared telephone numbers can be serviced only when all telephone numbers are assigned to actual physical ports.

1 illustrates an example in which a multiline is configured with actual physical ports in a conventional private exchange.

Hereinafter, an example in which a multiline is configured with actual physical ports in a conventional private exchange will be described with reference to FIG. 1. For example, a private exchange assigns 1000 unique phone numbers to port 0, 2000 unique phone numbers to port 1, and links ports 0 and 1 in software. In this case, the telephone connected to port 0 can use the 1000 and 2000 unique telephone numbers, and the telephone connected to port 1 can also use the 1000 and 2000 unique telephone numbers. First, when assigning a phone number to each physical port, 1000 unique phone numbers are assigned to port 0, and 2000 unique phone numbers are assigned to port 1. Then, when connecting a phone to each physical report, connect phone A to port 0 and phone B to port 1. In addition, telephone A shares the number 1000, which is the unique telephone number of port 0, which is actually connected, and the number 2000, which is the unique telephone number of port 1, which is software-linked. If the call comes to 1000, the ring rings at the phone A. If the call comes to 2000, the ring rings at both the phone A and the phone B at the same time. However, if telephone A first answers a call of 2000, telephone B, which is directly connected to port 1, the telephone number of 2000, cannot be used. Therefore, in this case, it results in the inability to use the phone B connected to the actual physical port 1.

As such, the multi-line service provided by the conventional private exchange cannot provide various phone numbers because of limitations of physical ports. In addition, in order to implement a multi-line service in a conventional private exchange, there is a problem that wastes physical ports unnecessarily.

In order to solve this problem, the conventional private exchange can assign a plurality of telephone numbers to one telephone by introducing a virtual number called a unique line. However, these virtual numbers cannot be shared by other phones, so they are not a true multiline service.

Accordingly, an object of the present invention is to provide a multi-line service method using a virtual port in a private exchange.

Another object of the present invention is to provide a multi-line service method that uses a telephone number assigned to a virtual port of a private exchange in an actual physical report.

The present invention for achieving these objectives is to designate a virtual port area in the database of the private exchange, and to assign a phone number for each port of the virtual port area by using a maintenance device, the actual telephone number assigned to the virtual port It is used for a telephone connected to a physical port.

The private exchange 200 is connected to the maintenance device 210 through an input / output processor module 201 (Input / Output Process Module) to send and receive messages to each other. The maintenance device 210 is installed with a maintenance program, and may be implemented as a terminal such as a computer. The private exchange 200 according to the present invention provides a multi-line service by controlling a virtual port through the maintenance device 210 connected to the input / output processor module 201. The private exchange 200 is connected to the telephones 221 to 22N, which are subscriber terminals, through the subscriber connection unit 202. The private exchange 200 receives the unique phone numbers of the actual physical port area and the unique phone numbers of the virtual port area through the maintenance device 210 and stores them in the memory 203. In addition, the private exchange 200 receives the port number corresponding to the unique telephone numbers as shown in FIG. 4 and whether the multi-line link is set through the maintenance device 210 and stores the received port number in the memory 203. In addition, the private exchange 200 receives the multiline linked port numbers corresponding to the respective unique telephone numbers and the key numbers of the telephones connected to the port numbers as shown in FIG. Store in memory 203.

2 and 5, in a private exchange according to a specific embodiment of the present invention, an area from 0x000 to 0x7ff is an actual physical port area, and an area from 0x800 is a virtual port area that does not actually exist. The maintenance apparatus 210 assigns a unique telephone number to the real physical port region and the virtual port region, respectively, as shown in FIG. 3 through the input / output processor module 201. Then, the private exchange 200 stores the unique telephone number corresponding to each port of the real physical port area and the virtual port area input from the input / output processor module 201 in the memory 203. When the maintenance apparatus 210 determines and sets a port number and a multi-line link corresponding to a unique telephone number as shown in FIG. 4 through the input / output processor module 201, the private exchange 200 stores the input value in memory. Store at 203. In addition, the maintenance device 210, through the input and output processor module 201 as shown in Figure 5 each unique telephone number and the port number that is software-linked with the unique telephone number and the key number of the telephone to which the unique telephone number is given When input, the private exchange 200 stores the input port number and key number in the memory 203. Then, the private exchange 200 according to the embodiment of the present invention provides a multi-line service by sharing a unique telephone number assigned to the virtual port area. That is, as the unique telephone number assigned to the virtual port area in the private exchange 200 according to the embodiment of the present invention is software-linked with a plurality of telephones connected to the actual physical port by the maintenance apparatus 210, the private exchange 200 is virtually connected. The port can be used to provide multiline services.

6 illustrates an example of configuring a multiline with a virtual port according to an embodiment of the present invention.

A method of providing a multiline service using a virtual port in a private exchange according to an embodiment of the present invention will be described with reference to FIGS. 2 to 6. As shown in FIG. 3, a virtual port area is designated in the database, and a unique telephone number is assigned to the virtual port area using the maintenance apparatus 210. For example, when 3000 is assigned to a virtual port 0x800 port, since a telephone cannot be actually connected to the virtual port, 3000 unique telephone numbers cannot be used without a multiline configuration. However, since 3000 unique phone number is set to multi-line link with port 0 which is a real physical port, phone A connected to port 0 can use both 1000 and 3000 unique phone numbers.

Therefore, the private exchange 200 according to the embodiment of the present invention enables the multi-link of the unique telephone number of the virtual port to be used in the telephone connected to the actual physical port. Then, the private switch 200 according to the embodiment of the present invention uses the unique telephone number assigned to the virtual port by using the multi-line link of the telephone connected to the actual physical port. Besides the unique phone number, you can use another 3000 unique phone numbers assigned to the virtual port. Therefore, when the private exchange 200 according to the embodiment of the present invention dials 3000, the call is received by the telephone A. FIG.

In addition, the maintenance device 210 is to share the unique phone number assigned to the virtual port in the switch 200 through the I / O processor module 201 to other telephones connected to the actual physical port to the multi-line service as shown in FIG. Enter the unique phone number and linked port number and key number.

For example, when a private call 200 receives a predetermined call with 3000 as a calling phone number assigned to a virtual port, the private exchange 200 searches a database stored in the memory 203 and displays the unique phone number 3000 as shown in FIG. Check the port number and multiline link setting. The private exchange 200 retrieves the port number and the key number linked to the unique telephone number 3000 as shown in FIG. 5 since the multi-line link is established at the unique telephone number 3000 to which the call is received. The private exchange 200 is the telephone number key of the telephone connected to the port OX800 linked to the unique telephone number 3000, the telephone number key of the telephone connected to the port OX000, and the telephone connected to the port OX0001. Call the number 3 on your phone. However, since the OX800 port is a virtual port in the private exchange 200, there is no telephone actually connected to the call, and the incoming call to 3000 is actually received by the telephone connected to the OX000 port and the OX001 port, respectively.

Therefore, the private exchange 200 according to the embodiment of the present invention can share multiple telephone numbers in multiple telephones without wasting physical ports by multi-linking unique telephone numbers assigned to the virtual ports to real physical ports. That is, the private exchange 200 according to the embodiment of the present invention may provide a multi-line service by linking a unique telephone number assigned to a virtual port to several real ports.

7 illustrates a process of providing a multi-line service using a virtual port in a private exchange system according to an embodiment of the present invention.

A method of providing a multi-line service using a virtual port in a private exchange system according to an embodiment of the present invention will be described with reference to FIGS. 2 to 7. In operation 710, the private exchange 200 determines whether a call is received by a unique telephone number assigned to an area of a virtual port, as shown in FIG. When the call is received at the unique telephone number assigned to the area of the virtual port, in operation 720, the private exchange 200 searches the memory 203 for a database indicating whether to establish a multi-line link of the unique telephone number as shown in FIG. . In operation 730, the private exchange 200 determines whether a multiline link is established for the call telephone number to which the call is received by referring to a database indicating whether the multiline link is established. If the multi-line link is established for the calling telephone number, in step 740, the private exchange 200 searches the memory 203 for a database according to the setting of the multi-line link as shown in FIG. In operation 750, the private exchange 200 determines whether there is a multiline linked port corresponding to the calling telephone number by referring to a database according to the setting of the multiline link. If there is a multi-line linked port corresponding to the calling telephone number, in operation 760, the private exchange 200 sends a ring to a telephone connected to the port multi-linked to the calling telephone number.

As such, the present invention does not actually exist in the private exchange, but designates a virtual port area in the database, and assigns a unique telephone number to each port of the virtual port area by using a maintenance apparatus. In addition, the telephone connected to the actual physical port line in the private exchange enables the unique telephone number assigned to the virtual port area through the maintenance apparatus. In addition, the present invention allows a private telephone number assigned to a virtual port area in a private exchange to be used in various telephones connected to actual physical ports. Therefore, the private exchange according to the embodiment of the present invention can not only give several telephone numbers to one telephone without limitation, but can also share with several telephones.

As described above, the present invention has an advantage in that it is possible to assign a plurality of telephone numbers to a single phone without waste of physical ports when performing a multiline service by assigning a telephone number to a virtual port in a private exchange.
