METHOD OF SELECTIVE INCOMING SIGNAL SERVICE IN INTELLIGENT NETWORK

摘要

PURPOSE: A method of a selective incoming signal service in an intelligent network is provided to protect an incoming subscriber and offer the service with privacy, by including an authentication function in an incoming call, and thereby allowing only a call that passes an authentication to be received. CONSTITUTION: When a call is income(201), this income call is subjected to the authentication(202). An authentication process of the income call is carried out, and then the income call is processed normally if the authentication of the income call has been successful(203). If the authentication thereof has been failed, the authentication thereof is performed again(204). The income call is processed normally if the authentication thereof performed again has been successful(203). If the number of authentication tries exceeds a preset number, a call release procedure is carried out(205).
