Using our example in Figurethe CalledPartyNumber parameter is included to indicate the toll-free number.
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. Before running it on an SCP platform, the SCE generally provides some level of simulation to determine how the service will function. These building blocks are easily recognizable as part of standard telephony call and feature processing. Note that these tables do not include all INAP operations.
The result is a complete logic program that can be executed.
Application context for SRF to SCF INAP CS1
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: 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.
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. User input is usually provided in one of the following forms:. The toll-free application at the SSP determines that communication with the SCP is necessary to retrieve information for the toll-free service. In the case of a toll-free or free phone call, charges are applied to the called party.
The program code is then generated for the service, which can be executed at an SCP. The InitialDP component can include several optional parameters. Like the various versions of AIN, INAP defines its own set of remote operations and parameters that are used at the component sublayer.

It could also include connections to an IP, along with many other variations in the message flow and parameters. 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. 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.
The Connect operation contains insp DestinationRoutingAddress parameter to specify the routable destination number for connecting the call. Example of User Interaction. However, the operations have been tailored to the needs of the European region, thus adhering to the ETSI specifications. SLPs provide the “glue” logic and overall program flow to join SIBs together into meaningful services.
While they provide similar functionality to those used by North American AIN, they are distinct in their definition and encoding.
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. This allows SPs to build and deploy their own services.
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. The code modules are triggered by incoming messages, which match a given criteria for the script, from the SSP.
The SLP is the executable logic that results from the service creation process. 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. Book Hosted by www.

inao This example is a very simple version of a toll-free service. Published By Cisco Press. Input is collected to make decisions about how a call should be directed and to determine the services the user needs. 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.
That would defeat the SIB’s “independence” aspect.
Audible messages can be used for a number of different purposes, including the following:. SIBs are currently quite generic and lack ample detail, making them primarily useful only for high-level modeling of service functions.
However, the fundamental building block of this SIB will still be needed.
