PURPOSE: A method for supplying an ACC(Automatic Collect Call) service based on an advanced intelligent network is provided to introduce the advanced intelligent network to the ACC service, so as to supply the ACC service by an automatic access system. CONSTITUTION: If an originator attempts an ACC(Automatic Collect Call) service call, an LE(Local Exchange) 'a' receives the ACC service call and generates an ACC service request signal to an SSP(Service Switching Point). If the SSP requests an origination number to the LE 'a', an SCP(Service Control Point) controls a service request by the origination number. The SCP decides whether a service supply is capable on the basis of a received request signal. If so, the SCP delivers an announcement to an LE 'b' through an IP(Intelligent Peripheral). The originator inputs a telephone number of a receiver in the announcement delivering process, and a name of the originator is recorded. A bell rings for the receiver, to inform the receiver of a collect call. If the receiver permits the collect call, a speech path of the originator is connected.
