Description

In-town / out-of-town TOLL electronic exchanger

[0001] The present invention relates to a TOLL full electronic exchanger for use in a suburban area and a suburban area, and more particularly, to a TOLL electronic exchanger which is designed to accommodate its subscribers in a TOLL electronic exchange, To an electronic exchanger.

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 outgoing termination exchange function is to automatically connect an incoming call that is coming from outside the coverage area of its central office to each receiving end station.

On the other hand, the number is made up of a local number which is a unique number of the area, a station number for distinguishing the group of the local subscriber connected to one exchange, and an identification number of each subscriber in one group. 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).

In general, the number translation in a local electronic exchange capable of local calls is performed by the translation of the identification number and the translation of the called number. After the translation of the identification number, if the local number is translated, the incoming number is translated to obtain the actual line to which the local station is connected, Respectively.

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-described configuration, when the other station number is transmitted to the mouth relay unit 10, the mouth relay unit 10 requests the number translation unit 15 to translate the identification number. Then, the number translating unit 15 translates the identification number based on the built-in predetermined database, and requests the exiting unit 40 to occupy the trunk line corresponding to the identification number.

Thereafter, when the outgoing unit 40 receives a notification that occupies the trunk line in the area, the incoming relay unit 10 transmits the stored destination number to the outgoing unit 40, Transmits the called party number transmitted from the incoming relay unit 10 to the counterpart exchange through the inter-station relay signal with the other exchanger, and connects the out-door call.

The conventional TOLL exchanger is designed to be a subway line exclusive exchange that only takes charge of a long distance call, so that there is a problem that the subscriber can not be accommodated to his / her own station.

Accordingly, the present invention has been made in view of the above circumstances and provides a TOLL electronic exchanger for both local and long-distance Toll-mode electronic exchanges designed to accommodate domestic subscribers, It has its purpose.

According to an aspect of the present invention, there is provided a mobile communication system including an incoming relay unit for receiving a number transmitted from another exchange, a subscriber connection unit for connecting a plurality of subscriber units to a number translation unit, Translating the number transmitted from the subscriber connection unit, if the identification number of the number is for the home country call, the local subscriber according to the corresponding number is called, and if the identification number of the corresponding number is a foreign station call, And an outgoing line for transmitting the number transmitted from the incoming relay unit and the subscriber connection unit to the other station exchange through the corresponding line, occupying a specific trunk line based on the request of the number translator, A TOLL all-in-one electronic exchange is provided.

Preferably, the number translator comprises an identification number information storage unit storing information on an identification number (PREFIX) and a subscriber information storage unit storing subscriber information, and the number translator stores the identification number information And distinguishes the local call and the other station based on the identification number information stored in the subscriber information storage unit and translates the called number based on the subscriber information stored in the subscriber information storage unit when the call is a local call.

According to the present invention configured as described above, when the identification number transmitted through the incoming relay unit is a self-station number, a call to the self-subscriber corresponding to the incoming call number subsequent to the identification number is performed, The subscriber number transmitted subsequent to the identification number is transmitted to the trunk line corresponding to the identified identification number, so that the local telephone exchange and the long-distance telephone exchange can be performed with the TOLL electronic exchange.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a block diagram of a TOLL-TOLL full-time electronic exchanger according to an embodiment of the present invention. In FIG. 2, reference numeral 10 denotes an incoming relay unit for receiving a number transmitted from another exchange, The subscriber (the A subscriber 22 and the B subscriber 24 as representative subscribers) is connected to the number translator 30 so that the number input by the subscriber is transmitted to the number translator 30, And a subscriber connection unit for causing a call to the subscriber requested to be connected to the translation unit 30 to be performed.

The identification number information storage unit 32 and the subscriber information storage unit 34 contain the identification number information stored in the identification number information storage unit 32, If the identification number of the number transmitted from the subscriber connection unit 20 is translated and the identification number is the other station number, the outgoing unit 40 is requested to connect the trunk line corresponding to the identification number, and if the identification number is the own number A subscriber line is allocated and a subscriber corresponding to the transmitted subscriber number is called after the identification number.

The identification number information storage unit 32 incorporated in the number translation unit 30 stores information on the identification number composed of the area number and the station number. The subscriber information storage unit 34 stores the identification number, For example, line information, service information, rating information, billing information, and the like.

Reference numeral 40 denotes an outgoing unit for connecting a corresponding trunk line to the specific trunk line when the trunk line translating unit 30 is required to connect to the trunk line transceiver 30, The station number and the called number (i.e., subscriber number) transmitted from the incoming relay unit 10 are transmitted to the trunk line via the outgoing unit 40. [

Next, the operation of the out-of-area / in-city TOLL total electronic exchanger according to an embodiment of the present invention will be described in detail with reference to the attached flowchart of FIG.

First, when a specific number is received in the mouth relay unit 10 or the subscriber connection unit 20 (step 201), the mouth relay unit 10 and the subscriber connection unit 20 are connected to the number translation unit 30 at the identification number Request the translation of the number.

The number translating unit 30 translates the identification number input from the incoming relay unit 10 or the subscriber connection unit 20 based on the identification number information stored in the identification number information storage unit 32 (Step 202), and judges whether the identification number is for the local call (step 203).

If it is determined that the identification number transmitted from the incoming relay unit 10 or the subscriber connection unit 20 is not a local call (NO in step 203), the number translator 30 transmits the outgoing call 40 To request the occupancy of the trunk of the area corresponding to the identification number. When the occupant notification signal corresponding to the trunk line occupies the trunk line in the outgoing tier 40 by the request and comes to the number translator 30, The ingress relay unit 10 or the subscriber connection unit 20 transmits the subscriber number according to the identification number to the outboard line 40 so that the corresponding subscriber number is transmitted to another exchange.

On the other hand, if it is determined in step 203 that the identification number transmitted from the incoming relay unit 10 or the subscriber connection unit 20 is a local call (YES in step 203), the number translation unit 30 transmits the subscriber information (Step 205), based on the subscriber information stored in the storage unit 34, the incoming call number transmitted subsequent to the identification number from the incoming call relay unit 10 and the subscriber connection unit 20.

Then, the number translator 30 obtains a subscriber line corresponding to the incoming call number based on the translated incoming number (step 206), and then requests the subscriber connection unit 20 to connect the subscriber corresponding to the subscriber line (Step 207).

The subscriber connection unit 20 connects the specific local subscriber requested by the number translator 30, and transmits a predetermined paging signal to the local subscriber so that a specific local subscriber is called (step 208).

For example, when the identification number of the corresponding TOLL prefix exchange is, for example, XXX (area code) -YY (station number), the number translator 30 (for example, XXX-YY-AAAA number) ) Determines that the call according to the corresponding XXX-YY is a local call, translates the incoming call number to AAAA, and calls the subscriber A (YY-AAAA) corresponding to the incoming call number.

On the other hand, when the identification number of the corresponding TOLL electronic exchanger is, for example, XXX-YY, the number translator 30 transmits the ZZZ-WW-RRRR number, for example, , The trunk of the area corresponding to the ZZZ-WW is occupied by the outgoing trunk 40 and the subscriber number (WW-RRRR) is transmitted to the trunk line.

When the subscriber A accommodated in the subscriber connection unit 20 inputs, for example, YY-BBBB, the number translator 30 determines that the call is a local call based on the YY, translates the incoming number to BBBB And the subscriber B (YY-BBBB) corresponding to the incoming number is called.

As another example, if the subscriber A accommodated in the subscriber connection unit 20 inputs, for example, ZZZ-WW-RRRR, the number translation unit 30 determines that the corresponding call is a foreign station call based on the ZZZ-WW, (WW-RRRR) is transmitted to the trunk line after the trunk line corresponding to ZZZ-WW is occupied.

As described above, according to the out-of-area / in-city TOLL total electronic exchange according to the embodiment of the present invention, when a call is made from the other exchange to the local subscriber, the local telephone exchange function is performed, If there is a call from the subscriber or other exchange to another exchange, the benefit of improving the utilization efficiency of the corresponding TOLL electronic exchange by enabling the inter-city / inter-office exchange through the TOLL electronic exchange by performing the inter- have.
