Vokasa The code modules are triggered by incoming messages, which match a given criteria for the script, from the SSP. It could also include connections to an IP, along with many other variations in the message flow and parameters. Several SCEs are available, each differing in features and capabilities; however, they all share c1s common purpose of generating program code that can be executed by the SCP. Note that these tables do not include all INAP operations.

The class of an operation is not stated explicitly but is specified in the ASN. The values operation codes and error codes are defined in a separate module. It is used for example for providing televoting -- or mass calling services.

Simple registration functionality counters and announcement -- control may be located at the SSF. The operation initializes the specified counters in the SSF.

If the relationship is still in existence, then the SSF will respond. If no reply is received, -- then the SCF will assume that the SSF has failed in some way and will take the appropriate -- action. To do so, the SSF may or may not use destination -- information from the calling party e.

The registered call record is intended for off-line charging -- of the call. The -- operation supports the capabilities to cope with the interactions concerning charging refer to -- Annex B, Clause B. In the local exchange this information may be used to update the -- charge meter or to create a standard call record. It may be used for inband -- interaction with an analog user, or for interaction with an ISDN user.

Any -- error is returned to the SCF. The timer associated with this operation must be of a sufficient -- duration to allow its linked operation to be correctly correlated. END Operation Timers The following value ranges do apply for operation specific timers in INAP: short: 1 to 10 seconds; medium: 1 to 60 seconds; long: 1 second to 30 minutes.

Table 3 lists all operation timers and the value range for each timer. The definitive value for each operation timer may be network specific and has to be defined by the network operator.



Shashura Each SIB identifies a common telephony function that is used across services. 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. 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. 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. It could also include connections to an IP, along with many other variations in the message flow and parameters.


Kajora Input is collected to make decisions about how a call should be directed and to determine the services the user needs. Figure shows the message flow for a basic toll-free service using 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. Using our example in Figurethe CalledPartyNumber parameter is included to indicate the toll-free number. 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.
