The present invention relates to a number translation service registration method in an electronic switching system.

The number conversion service does not only service new numbers that are changed when a random station number or called number is changed, but also registers the number conversion service to the existing number in the system so that the subscriber does not know whether or not to change the number and dials the existing number. If there is a number to connect a number or service through several networks, it is a service that allows the subscriber to dial a simple number and connects the call to a complex number connected through several networks. Every time a conversion service occurs, it becomes a hassle to create a new package.

Therefore, when a number conversion service occurs during system operation, there is a need for a system administrator to easily register a service through a simple command without creating a new package, so that operators can easily manage the number conversion service data.

As a result of the prefix type analysis (718), if the prefix type is a general prefix, the call type is analyzed (712). If the call type is a foreign call, the result message is sorted into a call type error (722). ).

As a result of call type analysis 712, if it is a native call, the called number of the number conversion number is analyzed (724) and it is checked whether it is a number accommodated in the system (725). If the number is accommodated in the system, the result message is sorted by the number already accepted (726), and the execution error message is output and terminated (727).

As a result of checking whether the number is accommodated in the system (725), if the incoming number is not accommodated in the system, a link for accommodating the number conversion number in the called number analysis database 500 (728) and finding the number conversion service database 600 is provided. Create a point (729) to store the number translation service database link point in the called number analysis database 500 (730) to find the number translation service database 600 as a link point (731) number translation service registration status set And a number translation service number (732).

Thereafter, the result message is sorted (733), and the execution success message is output and terminated (734).

The present invention enables the system operators to easily register the service through simple commands during operation, without making a new package each time the service number occurs, the operator can easily manage the number conversion service data, It also has the effect of providing efficient services to subscribers.
