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

1 is a configuration diagram of an intelligent network hardware for an intelligent network service at the time of origination in a general telephone network to which the present invention is applied.

The intelligent network hardware to which the present invention is applied includes an outgoing local exchange 104 which receives a service call from an intelligent network service user using an outgoing telephone 105 of a general telephone network, and an incoming telephone of a corresponding service subscriber who receives an incoming call and receives a service. An incoming local exchange 106 connected to the receiving local exchange 106, an intelligent network service exchange 103 connected to the outgoing local exchange 104 to transmit an intelligent network service call, and receiving a translated incoming number to perform a call processing function, the intelligent network A common line signaling network 102 for delivering service control information to a service exchanger 103 and a charge distance for an intelligent network service call from the intelligent network service exchanger 103 connected to the common line signaling network 102. Service control system 101 which performs number translation with the constructed service data, and number translation in said service control system 101. And a service management system 100 for managing the data for the necessary service period.

Here, when the intelligent network service exchanger 103 performs a call processing function, the service control system 101 converts the called number translated based on the charging distance to the called area of the called number based on the calling area of the calling number. Receives the call processing function.

FIG. 2 is a flowchart illustrating an intelligent network service call processing in the intelligent network service switch of FIG. 1, wherein a region-specific charging band is constructed based on a charging distance among a plurality of called numbers when an outgoing telephone 105 of a general telephone network is used to use an intelligent network service. By sequentially retrieving the information, a call forwarding processing flow is defined in the intelligent network service switch 103 for providing near field routing to a near destination number.

When the service user enters the intelligent network service identification number and the subscriber number using the telephone 105 of the general telephone network, the calling local exchange 104 determines the intelligent network service call based on the service identification number of the called number, and determines the intelligent network service switch 103 ). The intelligent network service exchanger 103 collects the calling number and the subscriber number to determine whether the intelligent network service call is transmitted to the service control system 101 (step 1). Based on this, the service control system 101 determines the calling telephone. Based on the calling number and the subscriber number of the service data and the number translation based on the charge distance for the intelligent network service call is performed and the processing result is transmitted to the intelligent network service exchange 103 (step 2).

By the way, if the processing in the service control system 101 fails, the failure announcement broadcast or the call is disconnected to the intelligent network service exchanger 103, while the processing in the service control system 101 is properly performed and the intelligent network When the service switch 103 receives the actual called number (step 3), the intelligent network service switch 103 processes according to the processing result (step 4).
