Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for translating a number in a local / regional / urban TOLL electronic switching system. BACKGROUND OF THE INVENTION 1. Field of the Invention < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for translating a number in a local / long-distance TOLL electronic switching system, and more particularly, The present invention relates to a number translation apparatus and method in a TOLL all-electronic exchanger for both in-the-city / in-city Toll where a number translation is performed by detecting only a subscriber number from a called number based on cut digits stored in the identification number information table.

As is well known, the conventional TOLL electronic exchanger (the out-of-home exchange) has two functions, that is, an out-of-area exchange and an out-of-area exchange, The exchange function is to automatically connect an outgoing call that goes out of its coverage area and the function of the outgoing extension exchange is to automatically connect incoming calls coming from outside its coverage area to each receiving end station.

On the other hand, a commonly used numbering system is composed of an area code, which is a unique number of the area, an area code for identifying a group of the local subscribers connected to one exchange, and an identification number of individual subscribers in one group Here, the combination of the station number and the called number is called a subscriber number, and the area number and the station number are collectively referred to as an identification number (PREFIX).

The number translation in the former electronic exchange capable of making a local call under the above-mentioned number system is performed by the identification number translation and the incoming number translation, and in the case where the call arrived after the translation of the identification number is a domestic call, Translate the subscriber line to which the subscriber of the local station is connected, and allow the subscriber of the local station to make a call. If the incoming call is the result of the translation of the identification number, the other exchange corresponding to the identification number transmits the corresponding identification number By transmitting the subscriber number, the other subscriber connected to the other station can make a call.

Next, a conventional TOLL total electronic exchanger will be schematically described with reference to FIG. 1 attached herewith.

As shown in FIG. 1, the conventional TOLL total electronic exchanger is composed of an input relay unit 10, a number translation unit 15, and an outgoing step unit 40.

In the conventional TOLL electronic exchanger having the above configuration, when the other station number is transmitted to the incoming relay unit 10, the incoming relay unit 10 requests the number translation unit 15 to translate the identification number . Then, the number translating unit 15 translates the identification number on the basis of a plurality of built-in identification number information tables, and requests the outgoing unit 40 to occupy the trunk line corresponding to the identification number.

The incoming relay unit 10 then transmits the stored called party number to the outgoing unit 40. When the outgoing unit 40 receives the notification that the outgoing unit 40 has occupied the trunk line, Transmits the called party number transmitted from the incoming relay unit 10 to another exchange through the inter-station relay signal with the other exchanger, and connects the out-door call.

In the conventional TOLL all-electronic exchanger, since the TOLL pre-electronic exchange is designed as a long-distance call exchanger which only takes charge of a long-distance call, there is a problem that it can not accommodate its own subscriber. A local / regional TOLL total electronic exchanger designed to accommodate a subscriber of the local station by incorporating a subscriber information table in the number translation unit 15 and further implementing a number translation function for the local call reception number has been proposed In fact.

However, the subscriber information table stored in the out-of-suburbs / in-city dual-use TOLL electronic exchanges includes a destination number when the subscriber is called from the subscriber of the same destination number, a destination number when the subscriber is called from the other subscriber, Since the subscriber information table is designed to have a number of subscriber information tables corresponding to the called number in case of being called, when the subscriber is newly registered or deleted in the TOLL prefix exchange, or when information of the subscriber is changed, The number of the subscriber information tables must be increased by the number of subscriber information tables, and a large amount of memory is required depending on the memory area allocated to the subscriber information table in the system .

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a method and apparatus for storing cut digit (CUT DIGIT) information indicated by the number of digits of the identification number in the identification number information table, The present invention provides a number translation apparatus and method in a local / regional TOLL all-in-one electronic switching system in which only a subscriber number can be detected in a called number based on digits and number translation can be performed.

According to an embodiment of the present invention for achieving the above object, there is provided a mobile communication system including: an incoming relay unit for receiving a called number transmitted from another exchange; and a relay unit for forwarding a call originated from the incoming relay unit and the subscriber An identification number information storage unit in which a binary number of cut digits corresponding to each identification number is recorded in an identification number information table (T1.T2.T3), a subscriber matching step for connecting a specific subscriber according to the type, A subscriber information storage unit configured to store information related to subscriber number translation, the subscriber information storage unit including a plurality of subscriber information tables, an identification number information table corresponding to the called station number by translating the identification number based on the information stored in the identification number information storage unit T1.T1.T3), and translates the subscriber number based on the information stored in the subscriber information storage unit on the basis of the cut digits A number translation unit having a number translation processor and an outgoing unit for occupying a specific trunk line based on the request of the number translation unit and transmitting the incoming call number of the other station transmitted from the subscriber matching station to another exchange, A number translation device is provided at the TOLL electronic exchanger for both urban / residential use.

According to another aspect of the present invention, there is provided a method for controlling a number translation processor, the method comprising: a first step of receiving digits according to a destination number transmitted from an incoming relay or a subscriber matching terminal; A second step of translating the identification number based on the stored information, a third step of judging a call type corresponding to the called number based on the translated identification number, and a third step of judging, from the determination result, (T1, T2, T3) corresponding to the called number,

T2), and if the call is a call to another station, the number translating processor requests a connection of a specific trunk line to the outgoing trunk, and when the trunk line is connected, the trunk line translates the call number A fifth step of detecting a subscriber number by deleting the read cut digit from the called party number of the local call; and a fifth step of, based on the information stored in the subscriber information storage unit, A sixth step of translating the subscriber number, and a seventh step of the seventh step wherein the number translation processor calls the local subscriber corresponding to the subscriber number via the subscriber matching terminal. / RTI >

FIG. 2 is a block diagram showing a block configuration of a TOLL / TOLL system in which the present invention is applied. In FIG. 2, reference numeral 10 denotes an incoming relay unit to which a called number transmitted from another exchange is transmitted to the corresponding TOLL exchange, 20 connects the number translator 30 with a number of local subscribers (the A subscriber 21 whose subscriber number is 555-5555 as its representative subscriber and the B subscriber 22 whose subscriber number is 555-6666) The number dialing unit 30 transmits the called number entered by the subscriber to the number translating unit 30 and performs a call from the number translating unit 30 to the requested subscriber.

In addition, reference numeral 30 denotes an interface for translating the identification number of the called number transmitted from another exchange through the mouth relay unit 10 and, if the called number is for the local call, And if the called number is for a foreign station call, the number is translated to the other exchanger through the outgoing unit 40. [0050] FIG.

As shown in FIG. 2, when the called number is transmitted from the incoming relay unit 10, the number translating unit 30 translates the identification number of the called number and then cuts a predetermined cut A digit translation processor for detecting only subscriber numbers from the called number based on the cut digits and performing number translation,

T2, and T3 based on the identification number information table T1, T2, and T3, as shown in FIG. 3, and a plurality of identification number information tables (e.g., T1, 31), an identification number information storage unit (32) for performing an identification number translation operation on the called number applied from the number translation processor (31) And a subscriber information storage unit 32 for performing a translation operation.

Reference numeral 40 shown in FIG. 2 is an outgoing unit for connecting a corresponding trunk line to the corresponding trunk line when the trunk line translating processor 31 of the number translator 30 requests connection of a specific trunk line And when the connection with the specific trunk line is completed by the outgoing trunk 40, the corresponding trunk number is transmitted to the other trunk through the trunk line via the trunk 40.

Next, referring to the attached flowchart of FIG. 4, a number translation method in a Toll-former electronic exchanger according to an embodiment of the present invention will be described in detail.

First, when a digit corresponding to a specific destination number is received by the mouth relay unit 10 or the subscriber identity unit 20, the received digit is applied to the number translation processor 31 in the number translation unit 30 (Step 100).

Then, the number translation processor 31 converts the digit into an identification number information storage unit

(Step 101). Then, it is determined whether the call corresponding to the digit corresponding to the digit is a local call (step 102).

On the other hand, if the identification number information table corresponding to the digit is not present in the identification number information storage unit 32 in step 101, the number translation processor 31 determines that the number is a different country code in step 102, And proceeds to step 103 according to the determination result (NO).

In step 103, the number translating processor 31 requests occupancy of the trunk of the area corresponding to the identification number to the escape stage 40. In response to the request, the escape stage 40 occupies the trunk line When the occupancy notification signal is transmitted to the number translating processor 31, the number translating processor 31 transmits the called number transmitted from the incoming relay unit 10 or the subscriber matching terminal 20 to the outgoing sub- 40) to another exchange.

If the identification number information table corresponding to the digit is present in the identification number information storage unit 32 and the corresponding call is determined to be a local call in step 102, the number translation processor 31 determines And proceeds to step 104 according to the determination result (YES).

In the step 104, the number translation processor 31 obtains a predetermined cut digit from the identification number information storage 32, where the number translation processor 31 reads out the identification number For example, the cut digit recorded in the flag of 3 bits allocated to the identification number information table corresponding to the digit applied to the information storage unit 32 and acquires the cut digit.

3, if the digits received from the incoming relay unit 10 or the subscriber identity unit 20 are, for example, '555-5555', the number translation processor 31 determines whether the digit ₍₂₎ 'from the identification number information table T1 configured in the identification number information storage unit 32 and transmits the cut digit to the mouth relay unit 10 and the subscriber matching unit 20 , The number translation processor 31 reads' 010 ₍₂₎ 'from the identification number information table T2 configured in the identification number information storage unit 31, for example, '02-555-5555'Quot; is read and acquired. If the digits received from the incoming relay unit 20 or the subscriber's mating terminal 20 are, for example, '00X-82-2-555-5555', the number translation processor 31 transmits the identification number Quot; 110 ₍₂₎ " in the identification number information table T3 configured in the identification information table 32 _{of the first embodiment} .

Then, the number translation processor 31 determines whether the received digit is '02-555-5555', for example, based on '010 ₍₂₎ ' read from the identification number information table T2, (Step 105). Then, the predetermined data is read from the subscriber information storage unit 33 based on the remaining digits, that is, '555-5555' (subscriber number), and number translation is performed (step 106).

Then, the number translation processor 31 obtains a subscriber line corresponding to the subscriber number based on the subscriber information read from the subscriber information storage unit 33 (step 107), and transmits the subscriber line to the subscriber matching terminal 20 And requests connection of the A subscriber corresponding to the subscriber line (step 108).

The subscriber matching unit 20 allows the A subscriber 21 requested by the number translation processor 31 to be connected and a predetermined paging signal to be transmitted to the subscriber of the local subscriber, Allows you to perform the call.

As described above, according to the apparatus and method for translating numbers in a TOLL-TOTAL electronic exchanger according to an embodiment of the present invention, the type of the called number, for example, '555-5555', '02-555-5555' The subscriber information storing means stores the same subscriber number, for example, '555-5555' as the type of the called number, that is, '555-5555', ' 02-555-5555 ', and' 00X-82-2-555-5555 ', whereas the subscriber information storage means employed in the Toll-former electronic exchange employing the present invention is composed of subscriber number For example, '555-5555', it is composed of a single subscriber information table corresponding to '555-5555' regardless of the type of the called number.

Therefore, according to the apparatus and method for translating a number in a local / regional TOLL total electronic exchange according to an embodiment of the present invention, a single subscriber information table is constructed for the same subscriber number regardless of the type of the called number, It is possible to easily perform deletion, modification, and registration of information on the subscriber information table, and to reduce the memory capacity allocated due to the subscriber information table in the system.
