Abstract: PURPOSE: A trunk billing method and system in a local exchange using an intelligent network is provided to connect a DOD(Direct Outward Dialing) line between a local exchange and a private exchange in a trunk method and to perform trunk billing in the local exchange through an intelligent network. CONSTITUTION: A call from an arbitrary extension subscriber connected to a subscriber interface unit in a private exchange is transferred to a calling-side local exchange(S10), the calling-side local exchange inserts a specific prefix for an intelligent network into the destination number and transfers the call to an SSP(Service Switching Point) connected through a PSTN(S12). The SSP triggers a trunk billing service call to an SCP(Service Control Point), based on the prefix, and transfers the origination number and the prefix+destination number to the SCP(S14). The SCP calculates a billing rate using the origination number and the destination number and requests the SSP to create a billing record for the origination number and to execute call routing to the destination number(S16). In response to the requests, the SSP creates the billing record(S20) and executes call routing to a called-side local exchange(S22).
