2 is a conceptual diagram illustrating a call processing performance according to the present invention.

First, in order to provide a local calling service, subscriber origin data is formed in the digit analysis function block, which is a called number analysis table, for each subscriber group to analyze received digits.

Then, after receiving the called number from the subscriber of the own station or another station, the called number is transmitted to the digit analysis function block (DA) using a software signal for analysis of the called number digit. The digit analysis function block analyzes the received digit first to determine how many subscriber sources the digit will be analyzed.

Obtaining information on the billing type from the digits analyzed by determining the subscriber source as described above, analyzing the billing through the Charging Analysis (CA) function block, and obtaining route information (RA: Route Analysis) is used to analyze routing through the function block.

And, if the analyzed digit is an end code, it is processed in a subscriber category (SC) functional block.

In more detail, the subscriber of the local call service does not use the subscriber source '0' used by the general subscribers in the digit analysis function block, the called number analysis table, but uses the same source to identify the source. A subscriber number analysis table is configured so that a subscriber can have a call by dialing only digits contracted with each other.

When designating an on-premises call subscriber group, the subscriber group can be designated individually or in various forms such as a teenager, a teenager, a teenager. For example, when the called party number analysis source is '3', in order to make the subscriber of the premises call as '3', '3-1' should be accommodated from '1000 to 1999'. 'To be accommodated' from 2200 to 2299 '. Then, '3-9' is allocated for identification with the external call subscriber, and in case of a domestic call, the called party number analysis source is assigned one number of '51 to 98 'for each local call subscriber group.

After configuring the called party number analysis table, the local call subscriber can dial 4 digits except for the station number when making a local call, and is analyzed at the subscriber source '3' of the called party number analysis table, and again allocated to the called party number analysis source table. Any number (51 to 98) is processed as a local currency local code.

When you want to make an external call, press '9' first to hear the redial tone, and the general subscriber is called at the subscriber origin '0' in the call processing or called number analysis table.

3 is a flowchart illustrating an outgoing call process for providing an internal call service according to the present invention.

When the digit is received from the subscriber (100), the digit received from the digit analysis function block, which is the called number analysis table (101), is analyzed (101).

In the case of the general subscriber, the general subscriber call processing is performed (103), and in the case of the subscriber of the local call service, the call type is analyzed (104) to determine whether it is an internal call or an external call (105).

In the case of an internal call, the billing data is analyzed (106), the charge is determined (107), and then processed as a terminating call (108).

In the case of an external call, routing information is analyzed (109) to determine a route (110), and billing data is analyzed (111) to determine charging (112).

4 is a flowchart illustrating an incoming call processing for providing an internal call service according to the present invention.

When receiving a digit from the originating exchange (200), the received digit is analyzed (201) to determine whether it is an incoming call or a relay call (202).

In the case of a relay call, relay call processing is performed (203), and in the case of an incoming call, the call type is analyzed (204) to determine whether the subscriber is a domestic call service subscriber or a general subscriber (205).

In the case of the general subscriber, the call is performed by performing the normal subscriber call processing (206), and in the case of the subscriber of the local call service, the call is performed by performing the internal call service subscriber call processing (207).
