Peripheral control in an intelligent network

摘要

An intelligent peripheral (IP) in a telecommunications network is operated under the control of a service control point (SCP). Control messages conforming to a standard control protocol, which may by INAP (the Intelligent Network Application Protocol) are passed from the SCP to the IP which then executes a predetermined function. Some of the control messages include a field identifying the messages as relating to an additional function not provided for in the standard protocol. In response to such a message the IP executes the relevant additional function instead of one of the standard functions.
