It is about.

Receivable intelligent network services such as toll-free 080 or representative number service can specify multiple destination numbers with a single intelligent network service number.For calls originating from a general telephone network, look at the calling area code and call the nearest destination from the calling area. The call is routed by number.

However, when the origination is a mobile network, since there is no information for estimating the origination area, the routing cannot be performed considering the origination place, and a method of connecting a service call to a fixed destination is used.

This method increases the share of network resources as the routing distance increases on the average, reducing network utilization efficiency, increasing the connection cost, and in the case of a large number of mobile network outgoing calls, concentrating calls to specific destinations, resulting in incomplete rates due to busy traffic. There is a disadvantage that increases.

Accordingly, the present invention has been made to solve the above-described problems, and provides the intelligent network service subscribers with better quality of service, and provides the service provider with the location information of the originating terminal at the time of mobile network transmission to efficiently utilize network resources. It is an object of the present invention to provide an apparatus and a method for performing source-based short-range routing by utilizing in a service.
