The present invention relates to a subscriber port assignment method of a switching system. In particular, the present invention is not limited to a virtual port so that a virtual port can be allocated to a real slot provided by inserting a real card. It is about how to assign.

In general, a virtual port in a switching system means logically allocating to a virtual slot that does not exist physically for a subscriber's call service. An example of a method of performing a call service by allocating such a virtual port is 1999-86364, which was filed by the applicant of the patent on May 27, 1998 and published on December 15, 1999. In addition to the aforementioned patent applications, many communication systems allocate a virtual port to provide a subscriber's call service.

1 is a schematic diagram illustrating a method for restricting allocation of virtual ports in a switching system according to the related art. In FIG. 1, reference numeral 10 denotes a switching system including a switching circuit 12, a subscriber connection unit 14 and an input / output processor 16, a control unit 18 for controlling all operations of the exchanger, and a memory 20 having a database having information on ports. to be. Here, the input / output processor is a processor for communication between the control unit of the switching system by inputting information such as MMC to install a port from an external maintenance terminal. This exchange system is identical to that already commercially available and widely used. The switching system 10 as described above has a real slot in which real hardware exists and a virtual slot in which no hardware exists.                         

FIG. 2 is a schematic diagram for describing in more detail a method for restricting allocation of a virtual port illustrated in FIG. 1. In FIG. 2, the switching system 10 includes a real slot for allocating an actual port, and the virtual slot for allocating a virtual port is not actually located inside the switching system 10.

The system according to the conventional virtual port allocation method configured as shown in FIG. 1 and FIG. 2 is to use the virtual port only for a legacy phone which is a conventional phone concept. For example, it is used when there is a shortage of lines, such as when two telephone numbers are assigned to one telephone line to use two or more telephones.

However, the conventional virtual port allocation method as described above has a problem in that it is not possible to provide an IP-phone service based on an Internet protocol (IP-based) as a virtual port. This is because virtual port mounting is possible only in virtual slots, and there are limited elements in which virtual ports cannot be mounted in real slots in which hardware of a switching system exists.

Accordingly, an object of the present invention is to virtually allocate a virtual port to a virtual slot or a real slot so that communication services can be provided not only for legacy phones but also for IP-phone mounting and services. The present invention provides a non-limiting allocation service method.

In the method of the present invention for achieving the above object, in the non-limiting allocation method of the virtual port in the switching system, the port area corresponding to the specified virtual port value in response to a virtual port installation command input from the outside is a real slot area Verifying the existence of a network port, and if the port region corresponding to the specified virtual port value does not exist in the real slot region, mounting a virtual port on a port corresponding to the virtual port value of the virtual port region. And if the port area corresponding to the designated virtual port value exists in the real slot area, mounting a virtual port on a real port corresponding to the virtual port value of the real slot area.

According to another aspect of the present invention, there is provided a call service method in a switching system, the method comprising: receiving an incoming digit code in response to an outgoing call of an IP-phone, and analyzing the received incoming digit code; Confirming the mounting location of the IP-phone, and if the IP-phone is located in the virtual slot as a result of the verification, connect the incoming signal to the IP-phone designated to the port of the virtual slot, If it is located in the real slot includes the step of connecting the IP-phone assigned to the port of the real slot by the number of the incoming digit code.
An apparatus of the present invention for achieving the above object, in the non-limiting allocation device of the virtual port in the switching system, a plurality of real slots having a plurality of real slots having a plurality of real ports, and a plurality of virtual ports By controlling a plurality of virtual slots having a plurality of virtual slots having a database, a database in which state information about the real port and the virtual port is stored, and a call call connected to the real port and the virtual ports, And a controller configured to non-limitably allocate a virtual port to the real slot and store the allocation information in the database in response to a virtual port install command from an external device, wherein the controller includes a virtual port install command input from an external source. In response, verify that the port area corresponding to the specified virtual port value exists in the real slot area. And if the port region corresponding to the designated virtual port value does not exist in the real slot region, the virtual port is mounted on a port corresponding to the virtual port value of the virtual port region, and the port region corresponding to the designated virtual port value If a corresponding port area exists in the real slot area, the virtual port is mounted on a real port corresponding to the virtual port value of the real slot area.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, in the following description of the present invention, it should be noted that a detailed description of a function or configuration for a known technical configuration may be omitted if it is determined that the present invention may unnecessarily obscure the subject matter of the present invention.

3 is a diagram illustrating a switching system implemented by a method for allocating virtual ports according to a preferred embodiment of the present invention. Referring to FIG. 3, the switching system 300 includes a switching circuit 310, a subscriber access unit 320, an input / output processor 330, a controller 340 for controlling overall operations of the exchanger, a memory 350 including a database having information on ports, and the like. Here, the input / output processor 330 is a processor for communicating with the controller 340 of the switching system 300 by inputting information such as MMC to install a port from an external maintenance terminal. This exchange system 300 is identical to that already commercially available and widely used. The exchange system 300 includes a real slot in which real hardware exists and a virtual slot in which no hardware exists. In this case, a virtual port to which an IP-phone can be connected is mounted in the switching system 300, and information about a real slot in the switching system 300 and the real port and the virtual ports corresponding to each of the virtual slots is stored in a database in the memory 350. It exists as. This configuration will be more clearly understood by FIG. 4.

4 illustrates a state in which a port is mounted in an exchange system implemented by a method for allocating virtual ports according to a preferred embodiment of the present invention. Looking at the configuration of the port of the entire system shown in Figure 4 as follows.

Switching System = 8 Shelves + 3 Virtual Shelf

1 slot = 22 slots (same concept as Slot = Card or Board)

One slot = 32 channels (Channel = Port).

In the switching system 10 configured as shown in FIG. 4, only a virtual port may be mounted in a range of “0X1800 to 0X2000”, which is a virtual port area. Here, the virtual port refers to an IP-phone that can be used only by IP without requiring real hardware.

In the real port range "0X0000 ~ 0X1800", virtual ports can be mounted as well as real ports that require real hardware. In other words, a virtual port means an IP-phone and a VoIP over Internet Protocol trunk, and when a user wants to use IP without actually mounting a real slot, the virtual port can be mounted in the real port area without being mounted in the virtual port area. .

5 is a flowchart illustrating a non-limiting allocation control flow of a virtual port according to a preferred embodiment of the present invention, and FIG. 6 is a flowchart of a call connection control flow to a virtual port by non-limiting allocation according to a preferred embodiment of the present invention. Figure is shown. Programs such as FIGS. 5 and 6 are masked in the memory 20 shown in FIG.

First, a process of selectively allocating a virtual port to either a virtual slot area or a real slot area in the switching system will be described with reference to FIGS. 3 to 5.

Now, when the exchange system operator inputs a virtual port installation command to use IP-phone or VoIP using an external maintenance terminal, it is input to the control unit 340 in the exchange system 300 through the input / output processor 330. The virtual port installation command is a command for designating a virtual port and includes a message and a port range value for determining whether to use the virtual port as an IP-phone or a VoIP.

In this case, the controller 340 for executing the program as shown in FIG. 5 confirms that the virtual port installation command is input in step 501 of FIG. 5, and checks the port range value input in step 503. That is, the value "0X000 to 0X2000" of the port boundary described in FIG. 4 is checked.

The controller 340 checks whether the virtual port range value input in step 505 exceeds the maximum port value (0X2000 = 8192 in decimal). If it is determined in step 505 that the value of the input virtual port exceeds the preset maximum port value, the controller 340 determines that the input is an error in step 507 and stops the processing at the same time. Send an error message to the maintenance terminal via.

If the checked virtual port value is determined to be a value within a range smaller than the maximum port value in step 505, the process proceeds to step 511 and the port corresponding to the port value input in step 511 is a real slot region. Check whether it exists in or in the virtual slot area.

If the value of the input port does not exist in the real slot region in step 511, the controller 340 mounts a virtual port corresponding to the corresponding value of the virtual port region in step 513 and sets the port state in the memory 350. Set the port information of the database.

However, if the value of the input port exists in the real slot region in step 511, the controller 340 mounts the virtual port in the corresponding region of the real slot in step 515 and sets the corresponding port information.

At this time, whether or not the virtual port of the port information of the database is as follows.

Whether or not virtual port of port summary information: 0 = IP-phone

                                 1 = IP trunk (VoIP)                     

                                 2 = real port otherwise

By the non-limiting allocation of the virtual port as shown in FIG. 5, the virtual port can be mounted in a real slot in which real hardware can be installed inside the switch, without limiting the limited use of the virtual port allocated only to the virtual slot. Can be assigned. Thus, expansion of IP-phone and VoIP trunk lines is facilitated. In addition, when operating the switching system where the number of lines is small, there is an advantage that port management becomes easy by using a real port area as an IP-phone rather than a virtual area.

Referring to Figure 6 attached to the process of performing the call service by assigning the IP-phone or VoIP to the real port or virtual port as described above in detail as follows.

Referring to FIG. 6, when an outgoing operation for calling an IP-phone in the switching system is performed from the VoIP network, the public network or the legacy phone in step 601, the controller 340 of the switching system may call the VoIP network or the public network in step 603 of FIG. 6. Or, it receives an incoming digit transmitted from the legacy phone.

After receiving the incoming digit in step 603, the controller 340 analyzes the incoming digit code in step 605, checks whether the corresponding IP-phone is in a real slot or a virtual slot, and checks whether it is located in the real slot in step 607. . The positioning of these slots is confirmed by reading the contents of the above-described port state database.

If the port corresponding to the current incoming digit code is not located in the real slot position in step 607, the controller 640 connects the incoming signal to the IP-phone connected to the virtual port in the virtual slot area in step 609.

On the other hand, if the port corresponding to the current incoming digit code is in the real slot position as a result of the check in step 607, the controller 340 moves to the IP-phone assigned to the real port of the real slot corresponding to the digit code received in step 611. Connect.

Thereafter, the controller 340 transmits a ring signal or a ring message to ring the ring to the connected IP-phone in step 613. By this process, the call between the caller (VoIP trunk line, public network, subscriber) and IP-phone is made in steps 615 and 617.

As described above, the virtual slots to which IP-phones, VoIP, and the like are connected to the real slots can be used to perform a call service, thereby making it possible to efficiently use and manage the ports.

As described above, the present invention manages ports by mounting virtual ports in real slots in which real hardware can be installed in the switching system, and thus, virtual ports can be allocated without limitation, making port usage and management easier. can do. In addition, by allocating virtual ports without restriction, it is possible not only to support IP-phone implementation and services, but also to include functions of existing legacy phones.
