Intelligent Network Services In Part 1 of this book, we examined the functional and physical characteristics of circuit switched based Intelligent Networks (INs). In this chapter, we are going to explore what these elements do by way of offering services to customers and giving carriers a flexible means of delivering new services. The IN service model was the first step to releasing service control from the hands of switch manufacturers and as such presented telecoms operators with a new vehicle for realising services that enhanced the basic call control capabilities of stored program control switches. . | Next Generation Network Services Neill Wilkinson Copyright 2002 John Wiley Sons Ltd ISBNs 0-471-48667-1 Hardback 0-470-84603-8 Electronic 10 Intelligent Network Services INTRODUCTION In Part 1 of this book we examined the functional and physical characteristics of circuit switched based Intelligent Networks INs . In this chapter we are going to explore what these elements do by way of offering services to customers and giving carriers a flexible means of delivering new services. The IN service model was the first step to releasing service control from the hands of switch manufacturers and as such presented telecoms operators with a new vehicle for realising services that enhanced the basic call control capabilities of stored program control switches. We see that this is not the end of the story for enhanced service platforms as the move to remove the final block to enhanced services the close coupling of the stored program controller and the switch fabric to release the potential of software driven services on packet networks. Just to refresh the reader on INs. They rely on the decoupling of a number of telephone switch functions from the stored program controller renamed a Service Switch Point SSP in the IN architecture. The functions left behind in the SSP are called the Basic Call State Model BCSM . The functions separated out are incorporated into a centralised service execution environment as a Service Independent Building Block SIB called the Basic Call Processing BCP function. The services constructed from SIBs to form a Service Logic Program SLP run inside this environment called the Service Logic Execution Environment SLEE inside a physical platform called the Service Control Point SCP . All of this distributed processing is facilitated by a protocol called 124 INTELLIGENT NETWORK SERVICES Signalling System Number 7 SS 7 . The remote method invocation protocol that runs on top of SS 7 is known as the Intelligent Network Application Part INAP . Mobile
