Introduction
This manual describes the following features:
•Prepaid IDP Query Relay (IDP Relay) - Provides a mechanism to ensure the correct charging for
calls from prepaid subscribers in a portability environment.
•Service Portability - Allows an own-network subscriber to port to a different network technology
with the same service provider.
•S-Port Subscriber Differentiation - Can be used with the Service Portability feature to allow use
of ASD digits to provide an additional Routing Number per own-network subscriber. (ASD
digits, if provisioned, are used in place of GRN digits).
•IDP Relay-related features: IDPR Additional Subscriber Data (IDPR ASD) and IDPR Generic Routing
Number (GRN) - Provide RTDB lookup to obtain ASD and GRN data for message formatting.
•IDP A-Party Blacklist - Provides subscriber blacklist checking on the Calling Party (A-Party or
CGPN) number in the IDP CAMEL or INAP message, and routing of the call to a predetermined
number when the call is flagged as blacklisted.
•IDP A-Party Routing - Provides routing of the IDP message based on the A-Party (Calling Party)
in the message instead of the SCCP CdPA.
•IDP Service Key Routing - Provides routing of the IDP message based on the Service Key and
EventTypeBCSM parameters in the message instead of the SCCP CdPA.
•IDP Screening for Prepaid - Provides a mechanism to decide, before routing calls to the prepaid
engine, whether checking the credit status of prepaid subscribers is required.

IntroductionFeature Manual - IDP-Related Features

Tekelec TAC Engineers are available to provide solutions to your technical questions and issues 7
days a week, 24 hours a day. After a CSR is issued, the TAC Engineer determines the classification of
the trouble. If a critical problem exists, emergency procedures are initiated. If the problem is not critical,
normal support procedures apply. A primary Technical Engineer is assigned to work on the CSR and
provide a solution to the problem. The CSR is closed when the problem is resolved.

Emergency Response
In the event of a critical service situation, emergency response is offered by the Tekelec Customer Care
Center 24 hours a day, 7 days a week. The emergency response provides immediate coverage, automatic
escalation, and other features to ensure that the critical situation is resolved as rapidly as possible.
A critical situation is defined as a problem that severely affects service, traffic, or maintenance
capabilities, and requires immediate corrective action. Critical problems affect service and/or system
operation resulting in:
•A total system failure that results in loss of all transaction processing capability
•Significant reduction in system capacity or traffic handling capability
•Loss of the system’s ability to perform automatic system reconfiguration
•Inability to restart a processor or the system
•Corruption of system databases that requires service affecting corrective actions
•Loss of access for maintenance or recovery operations
•Loss of the system ability to provide any required critical or major trouble notification
Any other problem severely affecting service, capacity/traffic, billing, and maintenance capabilities
may be defined as critical by prior discussion and agreement with the Tekelec Customer Care Center.

Feature Description
This chapter describes the Prepaid IDP Query Relay (IDP Relay) feature and the following IDP
Relay-related features:
•IDP Relay Additional Subscriber Data Feature
•IDP Relay Generic Routing Number Feature
IDP Relay interactions with the following features are described in this chapter; the features are
described in separate chapters:
•IDP A-Party Blacklist Feature
•IDP A-Party Routing and IDP Service Key Routing Features
The Prepaid IDP Query Relay feature (IDP Relay) provides a mechanism to ensure the correct charging
for calls from prepaid subscribers in a portability environment.
IDP Relay processes GT-routed INAP or CAP messages with ITU MTP/SCCP/TCAP parts and
Opcode=IDP. It does not process MTP-routed messages.
IDP Relay provides functions that handle complex numbering schemes and number conditioning,
such as the following examples:
•The Nature of Address Indicator (NAI) could be used in a non-compliant manner (the NAI is set
to International and the number format is not international).
•The Local Area Code (LAC) 2- byte field of the Local Area Identification (LAI) information element
is used in one of the following ways:
•As the Area Code in cases where the AC is needed but not provided in the CdPN
•To determine how to format the outgoing CdPN in the IDP query
•The collect call Escape Codes 90 and 90909 might need to be stripped and re-inserted after the RN.
•The Carrier Selection Point (CSP) can be removed from the incoming number and sometimes
re-inserted (as when the LAC is not equal to the AC).
•The RN for the CgPN might be needed when the call is identified as a collect call.
•Service Key selection could vary, and could require a change in the number of bytes present the
Service Key.
•Unsegmented XUDT messages might be required.
•Sometimes the RN but not the SP, or the SP but not the RN, or both the RN and SP are required in
the outgoing number format.
When Mobile Switching Centers (MSCs) in the network are configured to send IDP prepaid query
messages through the EAGLE 5 ISS, the EAGLE 5 ISS intercepts the IDP query based on a set of
configurable criteria, performs a number portability (RTDB) lookup on the called number, inserts the
portability information (Routing Number or HLR Address), and forwards the IDP query to a prepaid
SCP for processing. When a respective entry is found in the RTDB, any processing is controlled by
NPP Service Actions and configuration option provisioning in the TTROPTS table. The CdPN can be
modified with the portability information (Routing Number or HLR address) and the CgPN.
In standard IDP Relay processing, regardless of any actions performed on the IDP query by the IDP
Relay feature, the query is always forwarded to the prepaid SCP (PPSCP) for processing.When the
SCP receives the IDP query, all information necessary for call processing and billing is present. The
IDP Relay feature alleviates the need to launch a separate number portability database query.
16
910-6023-001 Revision A, March 2011
Prepaid IDP Query Relay FeatureFeature Manual - IDP-Related Features

IDP Relay also provides the following functions:
•CONNECT, CONTINUE, or RELEASECALL responses - Provisioning can allow CONNECT,
CONTINUE, or RELEASECALL responses to be sent based on the RTDB lookup results. A
configuration option determines whether the CutAndPaste parameter is included in a CONNECT
message that is sent from the Prepaid IDP Query Relay feature.
•Service Key-based GTA Routing (SK GTA Routing) - A provisioned Service Control Point (SCP)
Global Title Address (GTA) value based on the Service Key can be used to replace the SCCP Called
Party Address (CdPA) GTA in a message. This allows the IDP or IDPSMS message to be GTT
routed to the provisioned SCP GTA instead of to the incoming SCCP Called Party Address (CdPA)
GTA.
Number Portability Types
There are three types of Number Portability. IDP Relay supports all three types:
•Provider NP - the subscriber can move to another service provider and keep the same number
•Location NP - the subscriber can move to another location within the same service provider network
and keep the same number
This manual describes Provider NP and Location NP together as "NP".
•Service NP - the subscriber can move to another service technology (GSM or IS41) within the same
service provider network and keep the same number
This manual describes Service NP as "Service Portability" or "S-Port".
IDP Relay High Level Message Flow
IDP Relay processes messages in the following high-level message flow, as shown in Figure 1: Message
Flow for IDP Relay - Sheet 1 of 3 through Figure 3: Message Flow for IDP Relay - Sheet 3 of 3:
•Service Selection
•Component match
•Service Selector IDPR or TTR
•Identify number type and context
•ITU TCAP message with Op Code = IDP
•SCCP CdPA GTA matches an entry in the CSL GT list
•SK+BCSM present and matches a DS entry for the CSL SKBCSM list
•If the TTROPTS CGPACCCK configuration option indicates that an SCCP CgPA Check for a
Country Code match (STPOPTS DEFCC) is to be made, the SCCP GTI must indicate that GT is
present and the SCCP NAI must be International to allow the check to made.
•NPP Pre-processing
•TCAP DN present
•Number conditioning
•NPP Processing
•The IDPRCDPN, IDPRCDPN2, IDPRCDPN3, or IDPRCDPN4 service is called
•Conditioning Actions
