Whenever mention is made of intelligence in the context of communications it is not long before reference is made to IN. The IN in this case is an explicit reference to intelligent networks and very likely an explicit reference to the ITU/ETSI defined standards in Europe or AIN ANSI in America. But this is only one specific instance of the intelligence design patterns. To represent the span of intelligence design patterns as IN is to represent by analogy all knots with the reef knot.Intelligence continues to be a tool that the telecommunications industry wields to tackle the complexity of service design, to try to reduce the cost of service development (through platform reuse), and to emulate the productivity of the software industry by adopting converged technology approaches to improve service creation productivity.This paper briefly maps out the design patterns that are considered intelligent, ranging from the service node concept, the classical intelligent network, the service delivery platform, the distributed application server, through to enterprise intelligence and the intelligent client, in each of which we can see repeating mechanisms, such as service triggering and service selection.
