In addition, the central control subsystem 300 includes a network management subsystem (NMS) 301 for managing the entire network, and a statistics management subsystem (MSS) for collecting and managing various statistical data. 302 and an operator matching processing subsystem (MMS) 303 for matching with an operator.

Accordingly, the number handling subsystem (NHS) 201 to which the present invention is applied in the switching system configured as described above receives the number system and the route of the public telephone network and analyzes the subscriber's digit information and the signal information between stations. RCO (Route) which performs number translation (NTR) block and routing function as a sub-system that controls the origination or reception of group subscribers such as function to search the location of caller and called party and private branch exchange (PBX) Control) block, PBXC (PBX Control) block for controlling the group subscriber incoming.

2 is a configuration diagram of a database according to the present invention, wherein the home direct service number database has a sequential structure as many as the home direct service number provided by the system. The home direct service short code 401 becomes a key to access the corresponding tuple 405, the home direct service registration state 402, the home direct service number length 403, and the home direct service number 404, etc. It consists of information.

FIG. 3 is a flowchart of service registration for homeland direct service according to the present invention. When the homeland direct service registration is requested (501), an input parameter (shortcode, homeland service number) is received and arranged (502). After analyzing the homeland direct service number that has been received (503), it is determined whether the homeland direct service number is an international number that can be serviced (504). If the service is not an international number that is available for service, error processing is terminated (505). If it is a possible international number, locate the corresponding tuple of the home direct service database using the short code as a key (506) and register the home direct service (507) and convert the home direct service number corresponding to the input short code into the home direct service database. After storing (508), the execution success message is output and terminated (509).

4 is a flowchart of performing a homeland direct service according to the present invention. Upon receiving a homeland direct service short code from a subscriber (601), information on a corresponding outgoing line is obtained (602), and it is checked whether it is registered in the homeland direct service ( 602. If not registered, error processing is terminated (604). If registered, the homeland direct service number is obtained from the homeland direct service database using the received short code (605).

After extracting a digit from the homeland service number obtained from the homeland service database, the digit is analyzed (606), and the determined prefix state is an acceptable prefix (607). If the prefix is accepted in the system, the prefix information is obtained (609).

It is determined whether the type of the prefix is a general prefix among the obtained prefix information (610). If the type of the prefix is not a general prefix such as a special service registration or cancellation code or a code for a subscriber line test, the error number is notified and an error is processed. If the prefix type is a general prefix, it is determined whether the call type is an international number (612).

If the call type is not an international call, an error process is performed after the call type is terminated (613). If the call type is an international call, the class of the calling line and the class of the call type are compared (614). If the call type is lower than the call type, the call is notified and terminated (615). If the outgoing line level is higher than or equal to the call type, it is information for establishing outgoing call. The relay line occupied time point and the deleted digit length are obtained (616), and the relay line occupied time point is analyzed (617).
