These building blocks are easily recognizable as part of standard telephony call and feature processing. When the service has been constructed using the SCE tools, code modules or program scripts that are eventually ce1 to the SCP or Adjunct are generated. Further modifications and customizations are applied by setting the properties that are associated with the ianp level objects and often by making software modifications at the software coding level.
However, the operations have been tailored to the needs of the European region, thus adhering to the ETSI specifications.
The example has been kept simple to provide an understanding of what a simple INAP exchange looks like for a service and to avoid the varying nuances of how the service might be deployed.
It could also include connections to an IP, along with many other variations in the message flow and parameters. Before running it on an SCP platform, the SCE generally provides some level of simulation to determine how the service will function. Example of User Interaction.

That would defeat the SIB’s “independence” aspect. The SLP is the executable logic that results from the service creation process. The two most common functions involving User Interaction are collecting information from the user and playing audible messages or tones.
Each SIB identifies a common telephony function cz1 is used across services. In the case of a toll-free or free phone call, charges are applied to the called party. The SCE allows subcomponents that make up an SIB to be joined together in a logical flow with decision branch points based on the results of the subcomponent operations.
As the network and services evolve, new means for interacting with the user will inevitably surface, thereby adding additional operations to the User Interaction SIB. SLPs provide the “glue” logic and overall program flow to join SIBs together into meaningful services. The Apply Charging operation indicates that charging should be applied for the call and might contain a PartyToCharge parameter to indicate whether charges should be applied to the calling or called party.
An example of some SIBs include: The Connect operation contains the DestinationRoutingAddress parameter to specify the routable destination number for connecting the call. The operation within the User Interaction SIB that implements inxp collection of digits does not determine how the digits will be used.
Depending on regulatory policies and agreements, information such as the Carrier parameter can be returned in the Connect component to specify a particular IXC-providing service for the freephone number. The InitialDP component can include several optional parameters.
Many SCEs provide a Graphical User Interface that allows software components to be joined together at a high level using visual tools to represent a service. No part of this book maybe reproduced or transmitted in any form or by any means, electronic or mechanical, including photcopying or recording, or by any information storage and retrieval system, without written permission from the publisher, except for the inclusion of brief quotations in inp review. This allows SPs to build and deploy their own services.
However, the fundamental building block of ihap SIB will still be needed. The code modules ianp triggered by incoming messages, which match a given criteria for the script, from the SSP. Several SCEs are available, inp differing in features and capabilities; however, they all share a common purpose of generating program code that can be executed by the SCP.
Figure shows the message flow for a basic toll-free service using INAP. This example is a very simple version of a toll-free service. The result is a complete logic program that can be executed.
Like the various versions of AIN, INAP defines its own set of remote operations and parameters that are used at the component sublayer. Published By Cisco Press. Good simulators allow phone calls to be placed using resources such as recorded announcements and Voice Recognition Units, to provide a complete simulation of the service.
User input is usually provided in one of the following forms:. Additional operations for communication, such as SCF-SCF, exist; however, this section focuses only on those operations that are directly related to services at an SSP. Book Hosted by www. Figure shows an exchange between the SSP and SCP that requires the user to enter information based on voice prompts.
Whether the service is constructed using graphical tools or programming libraries, the end result must be able to run on the SCP platform.
