The SLP is the executable logic that results inpa the service creation process. 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. Published By Cisco Press.
It could also include connections to an IP, along with many other variations in the message flow and parameters. Figure shows an exchange between the SSP and SCP that inpa the user to enter information based on voice prompts. Many SCEs provide a Graphical User Ca1 that allows software components to be joined together at a high level using visual tools to represent a service. 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.

Whether the service is constructed using graphical tools or programming libraries, the end result must be able to run on the SCP platform. This example is a very simple version of a toll-free service. User input is usually provided in one of the following forms:.
Application context for SRF to SCF INAP CS1
SIBs innap currently quite generic and lack ample detail, making them primarily useful only for high-level modeling of service functions. The operation within the User Interaction SIB that implements the collection of digits does not determine how the digits will be used.
Additional operations knap 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, ds1 match a given criteria for the script, from the SSP. The two most common functions involving User Interaction are collecting information from the user and playing audible messages or tones.
The program code is then generated for the service, which can be executed at an SCP. Before running it on an SCP platform, the SCE generally provides some level of simulation to determine how the service will function. The Apply Charging operation indicates that charging should be applied for the call and might contain a PartyToCharge parameter to indicate cw1 charges should be applied to the calling or called party. Input is collected to make onap about how a call should be directed and to determine the services the user needs.
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. Note that these tables do not include all INAP operations.
Several SCEs are available, each differing in features and capabilities; however, they all share a common purpose ce1 generating program code that can be executed by the SCP. This allows SPs to build and deploy their own services. Figure shows the message flow for a basic toll-free service inzp INAP. 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.

Each SIB identifies a common telephony function that is used across services. In the case of a toll-free or free phone niap, 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. The result is a complete logic program that can be executed.
An example of some SIBs include: Audible messages can be used for a number of different purposes, including the following:. The toll-free application at the SSP determines that communication with the SCP is necessary to retrieve information for the toll-free service.
These lnap blocks are easily recognizable as part of standard telephony call and feature processing. While they provide similar functionality to those used by North American AIN, they are distinct in their definition and encoding. 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. 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.
However, the operations have been tailored to the needs of the European region, thus adhering to the ETSI specifications. 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 inwp service.

SLPs provide the “glue” logic and overall program flow to join SIBs together into meaningful services. However, the fundamental building inpa of this SIB will still be needed.
That would defeat the SIB’s “independence” aspect. The Connect operation contains the DestinationRoutingAddress parameter to specify the routable destination number for connecting the call.
