Number translation method in electronic exchange

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a number translation method in an electronic exchange, and more particularly, to a number translation method for providing a more diverse and rich phone number by providing an enblock (located) number translation method in an electronic exchange.

In the conventional electronic switch technology, the subscriber number is composed of a station number and a called number. In the case of downtown Seoul, the subscriber number is composed of a maximum of eight digits. In order to translate the number of the subscriber number, the exchange first performs translation of the station number to detect whether the corresponding station number is its own station number or another station number, and also analyzes how many called party numbers of the corresponding station number is used to display only the digits. Accept and analyze to answer or route a call.

However, in the related art, it is difficult to obtain a desired number of subscribers because the subscribers of the telephone exchange use limited resources of the telephone number, and thus, the special number which is popular by dividing the popular number and the unpopular number is limited subscriber. There was a defect that should be assigned only to.

The present invention has been made to solve the above-mentioned drawbacks of the prior art, and when the request for translation of an in-block number is received for the in-block number type call processing, the number can be occupied or routed by in-block number translation. The purpose is to make it.

The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings.

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

The configuration of the present invention receives the incoming call number from the calling subscriber to the originating call processing unit 100 and the number translation request received from the outgoing call processing unit 100 to translate the number and send the result call originating call processing unit 100 And the number translation unit 110 transmitted to the incoming call processing unit 120, and the number translation unit 110 in the case of the in-block station number in the case of in-block telephone number corresponding to the in-block telephone number from the number translation unit 110; Receiving the number information request and receiving the number 112 and the location information of the recipient according to the number translation results from the number translation unit 110 and the number translation unit 110 receives the number information to determine whether the recipient is in your country / country It is composed of the incoming call processing unit 120 to determine and connect with the called party or the other station.

Referring to Figure 1 for the system block diagram of the electronic switching system suitable for translating numbers, the call processing unit is divided into the outgoing call processing unit 100 and the incoming call processing unit 120, the outgoing mobile call control block is called party The number translation unit 110 transmits the number translation request.

The number translation unit 110 translates the number and translates the number, and transmits the result to the outgoing call processing unit 100 and the incoming call processing unit 120 and connects the called party and the calling party according to the translated number. If the station number translation request is received from the originating call processor 100, the station number is translated and the in-block station number is requested by the corresponding call processing block.

The number translation unit 110 searches for the in-block called number table when receiving the in-block called number, and converts the incoming call to the other number if the called number is the other country. Then, the station number translation is performed again to find and route the routing information, and the other call notification is sent to the call processing block.

The database 112 has an in-block called number table, and in the case of an in-block station number by translating the number from the number translator 110, the in-block called number according to a search command corresponding to the in-block telephone number from the number translator 110 The table is searched and the corresponding in-block telephone number is converted into a general telephone number and transmitted to the number translation unit 110.

Incoming call processing unit 120 is a block for controlling the call of the subscriber to be received, receives the number translation result from the number translation unit 110 and the location information of the called subscriber according to the number translation result from the number translation unit 110 It determines whether the called party is own / other country and plays the role of connecting to the called party or the other country.

Referring to FIG. 2, a step of translating a number in an electronic exchange is described. The originating call processor 100 receives a number input from a subscriber and transmits the number to the number translator 110. A station number translation request is received from the outgoing call processor 100 (step 202).

The station number is the first digit of the telephone number indicating a station consisting of 1 to 4 digits, and currently there are 2 to 4 digits in Korea.

The number translation unit 110 performs a station number translation to determine whether it is an in-block station number or a general station number (step 204).

For example, in the case of the in-block method, the station number is assigned to the station number, such as "777," and the number translation unit 110 translates the station number to determine whether the input station number is the station number allocated in the in-block method. .

If the result of translating the station number as determined in step 204 is a general station number instead of an in-block station number, the process proceeds to the step of determining whether the other station number or the local call station number is to be processed by translating the number according to the general station number.

If it is determined in step 204 that the result of translating the station number is the in-block station number, the inbound station number is notified to the calling call processor 100 (step 206).

The number translation unit 110 receives the in-block called number from the outgoing call processing unit 100 (step 208).

For example, the current telephone is composed of 24 alphabetic characters except "Q" and "Z" out of the 26 alphabetic characters located at the bottom of the telephone number, and is configured as "777-CHINA", that is, "777-24462". And, by inserting the Hangul code with the alphabet letters at the bottom of the phone number to configure "777-China" so that the general users can recognize the memorization of the number as a character rather than a number.

The number translation unit 110 receiving the called party number inquires the database 112 and converts to the general number corresponding to the called party number (step 210).

The number translation unit 110 receives the number corresponding to the called party number converted in the database 112 and translates the converted number (step 212).

The number translation unit 110 determines whether the number translated number is a local code (step 214).

If it is determined in step 214, if it is the own station, it transmits the incoming call occupancy request of the local station and switches to the channel of the called party of the corresponding station to connect the call path (step 216).

If it is determined in step 214 that it is another station number, a routing request is sent to the other station so as to be connected with the called party number of the other station (step 218).

As described above, in the present invention, when an in-block number translation request is received for an in-block number type call processing in an electronic exchange, the present invention translates the number in the in-block number to occupy or route the incoming call to provide a more diverse and rich phone number. It relates to a number translation method provided to the desired subscriber.

The principles of the invention have been described above in connection with specific devices, which are described by way of example only, and are not intended to limit the scope of the invention as described in the appended claims.
