Abstract: PURPOSE: An IP(Intelligent Peripheral) distributing method in an Internet network is provided to effectively cope with an increase in subscribers by effectively connecting a plurality of SSPs(Service Switching Point) and IPs when expanding them according to an increase in a subscriber capacity in an intelligent network, and provide a service without software change even if the IP is kept expanding to the intelligent network in the future. CONSTITUTION: When an operator inputs an IP list for its connection to each SSP through an OMP(Operation and Maintenance Processor), a message handler of an SCP(Service Control Point) receives it through an MMCD(Main-Machine Command Dialog) and stores it in a shared memory(S1). When an SLEE(Service Logic Execution Environment) receives an intelligent network call from an arbitrary SSP, it determines whether a specific service has been registered on the basis of information on an originating number and a termination number of the intelligent network call(S2). If a specific service has been registered for the intelligent network call, the SLEE determines whether a specific IP has been registered for the arbitrary SSP(S3). If a specific IP has been registered for the arbitrary SSP, the SLEE determines whether the specific IP registered for the arbitrary SSP is in an available state(S4). If the specific IP is in an available state, the SLEE selects the specific IP registered for the arbitrary SSP(S5). The SLEE determines whether an IP to be connected to the specific service registered for the intelligent network call has been registered(S6). If the IP to be connected to the specific service registered for the intelligent network call, the SLEE selects the IP to be connected to the specific service and connects the IP to the arbitrary SSP to proceed with the intelligent network call(S7).
