The two most common functions involving User Interaction are collecting information from the user and playing audible messages or tones. 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.
The Connect operation contains the DestinationRoutingAddress parameter to specify the routable destination number for connecting the call. While they provide similar functionality to those used by North American AIN, they are distinct cs11 their definition and encoding.
Like the various versions of AIN, INAP insp its own set of remote operations and parameters that are used at the component sublayer. Example of User Interaction. 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.
Input is collected to make decisions about how a call should be directed and to determine the services the user needs. That would defeat the SIB’s “independence” aspect.
The code modules are triggered by incoming messages, which match a given criteria for the script, from the SSP. The program code is then generated for the service, which can be executed at an SCP. 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.
In the case of a toll-free or free phone call, charges are applied to the called party.
Application context for SRF to SCF INAP CS1
An example of some SIBs include: 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. Using our example in Figurethe CalledPartyNumber parameter is included to indicate the toll-free number.
Each SIB identifies a common telephony function that is used across services. Additional operations for communication, such as SCF-SCF, exist; c1, this section focuses only on those operations that are directly related to services at an SSP.
The InitialDP component can include several optional parameters. Book Hosted by www. 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:. Good simulators allow phone calls to be placed using resources sc1 as recorded announcements and Voice Recognition Units, to provide a complete simulation of the service. The result is a complete logic program that can be executed. 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.

Before running it on an SCP platform, the SCE generally provides some level of simulation to determine how the service will function. However, the fundamental building block of ce1 SIB will still be needed. Figure shows an exchange between the SSP and SCP that requires the user to enter information based on voice prompts.
Further modifications 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.
These building blocks innap easily recognizable as part of standard telephony call and feature processing. Figure shows the message flow for a basic toll-free service using INAP.
The toll-free application at the SSP determines that communication with the SCP is necessary to retrieve information for the toll-free ca1. However, the operations have been tailored to the needs of the European region, thus adhering to the ETSI specifications. Audible messages can be used for a number of different purposes, including the following:.
The operation within the User Interaction SIB that implements the collection of digits does not determine how the digits will be used.
Published By Cisco Press. This allows SPs to build and deploy their own services. SIBs are currently quite cs11 and lack ample detail, making them primarily useful only for high-level modeling of service functions.
Note that these tables do not include all INAP operations. It could also include connections to an IP, along with many other variations in the message flow and parameters. 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.
