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 to transmit to the incoming call processing unit 120, the number translation unit 110 receives the in-block telephone number information request corresponding to the in-block telephone number by translating the number in the number translation unit 110 Receiving the number translation result and the location information of the called subscriber according to the number translation result from the number translation unit 110 and the number translation unit 110 to determine whether the called party is a foreign country or a corresponding called party. Or it consists of an incoming call processing unit 120 for connecting to 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 transmits the translation result to the outgoing call processing unit 100 and the incoming call processing unit 120, and according to the number translation result to connect between the called party and the outgoing subscriber, When the station number translation request is received from the call processing unit 100, the station number is translated and in the case of the in-block station number, the in-block called number is requested to 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 is provided. 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 providing an in-block number service in an electronic switch is provided. The outgoing call processor 100 receives a digit input from a subscriber, that is, receives a number (step 202).

The originating call processing unit 100 determines whether station number reception is completed among the input digits (step 204).

The station number is the first digit of the telephone number indicating a station consisting of 1 to 4 digits. Currently, the country has 2 to 4 digits.

If it is determined in step 204 that the station number has not been received, the process loops back to receiving a digit input from the subscriber and waits for a digit input for a predetermined time.

If it is determined in step 204 that the station number has been received, the number translation request is made to the number translation unit 110 for the received station number (step 206).

The originating call processing unit 100 receives the station number translation result from the number translation unit 110 (step 208).

If the station number translation result is determined by the number translation unit 110 and receives the in-block number, a digit in-block called number is received from the subscriber (step 210).

The originating call processor 100 periodically determines whether the received digit is the last digit (step 212).

The outgoing call processing unit 100 determines that the received digit is the last digit, if the "#" or "*" displayed on the telephone is input after the inblock number is input, the input of the inblock number is terminated. To judge.

If it is determined in step 212 that the received digit is not the last digit, it loops back to step 210 for receiving a digit input from the subscriber and waits for a digit input for a predetermined time.

If it is determined in step 212 that the received digit is the last digit, the outgoing call processor 100 notifies the number translator 110 of the received number to translate the number and the number translator returns to the incoming call processor 120. Translating the number of the called party number to be called to the number to connect the call between the called party and the calling party (step 214).

For example, when "1234567890" is input, the outgoing mobile call processing unit 100 transmits this number to the number translation unit 110, and the number translation unit 110 transmits the called number corresponding to "1234567890" in the database 112 ) To determine whether it is a local call or a foreign call and transmits it to the incoming call processor 120 so that a call is connected between the called party and the calling party corresponding to the corresponding "1234567890".

As described above, the present invention provides an in-block number translation function to a general subscriber in an electronic switching system, and uses an in-block number system to set a character or a random number set by the subscriber. By providing various numbers to the subscriber and entering the provided number, the call is received by the corresponding telephone, thereby providing various services using the general subscriber phone.

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.
