SIBs are currently quite generic and lack ample detail, making them primarily useful only for high-level modeling of service functions. When the service has been constructed using the SCE tools, code modules or program scripts that are eventually deployed to the SCP or Adjunct are generated. Example of User Interaction.

Before running it on an SCP platform, the SCE generally provides some level cx1 simulation to determine how the inqp will function. It could also include connections to an IP, along with many other variations in the message flow and parameters.
The Connect operation contains the DestinationRoutingAddress parameter to specify the routable destination number for connecting the call. These building blocks are easily recognizable as part of standard telephony call and feature processing.
INAP – Wikipedia
The code modules are triggered by incoming messages, which match a given criteria for the script, from the SSP. The operation within the User Interaction SIB that implements the collection of digits does not determine how the digits knap be used.
Input is collected to make decisions about how a call should be directed and to determine the services the user needs.
Like the various versions of AIN, INAP defines its own set of remote operations and parameters that are used at the component sublayer. Further inwp and customizations are applied by setting the properties that are associated with the high level objects and often by making software modifications at the software coding level.
However, the fundamental building block of this SIB will still be needed. 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.
This allows SPs to build and deploy their own services. 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.
That would defeat the SIB’s “independence” aspect.
The InitialDP component can include several optional parameters. This example is a very simple version of css1 toll-free service. However, the operations have been tailored to the needs of the European region, thus adhering to the ETSI specifications. Book Hosted by www. User input is usually provided in one of the following forms:. Additional operations for communication, such as SCF-SCF, exist; ihap, this section focuses only on those operations that are directly related to services at an SSP.
In the case of a toll-free or free phone call, charges are applied to the called party. Each SIB identifies a common telephony function that is used across services. The two most common functions involving User Interaction are collecting information from the inal and playing audible messages or tones.

Using our example in Figurethe CalledPartyNumber parameter is included to indicate the toll-free number. 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. Figure shows an exchange between the SSP and SCP that requires the user to enter information based on voice prompts.
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 a review.
The result is a complete logic program that can be executed. The toll-free application at the SSP determines that communication with the SCP is necessary to retrieve information for the toll-free service.
Figure shows the message flow for a basic toll-free service using INAP.
Note that these tables do not include all INAP operations. Audible messages can be used for a number of different purposes, including the following:. Whether the service is constructed using graphical tools or programming libraries, the end result must be able to run on the SCP platform. Several SCEs are available, each differing in features and capabilities; however, they all share a common purpose of generating program code that can be executed by the SCP.
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. Depending on regulatory policies and agreements, information such as the Onap parameter can be returned in the Connect component to specify a particular IXC-providing service for the freephone number. The program code is then generated for the service, which can be executed at an SCP.
