it is desirable to continue message processing, even though the database might not be as up-to-date
as it could be.
• When a Service Module card is booted, if it is determined that the card does not have sufficient
memory to hold the entire database, the database is not loaded on that card. The Service Module
card is responsible for recognizing and reporting out-of-memory conditions. Under this condition,
a Service Module card cannot process provisioning traffic.
Introduction to Platform Services
The PDBI allows one or several independent information systems supplied and maintained by the
network operator to be used for provisioning the G-Flex, G-Port, INP, EIR, A-Port, IS41 GSM Migration,
V-Flex, and AINPQ databases and for configuring the G-Flex, G-Port, INP, EIR, A-Port, IS41 GSM
Migration, and AINPQ systems. Through the PDBI, the independent information systems can add,
delete, change or retrieve information about any IMSI/MSISDN/SP association or portability
information.
The active/standby status of the PDBA can also be changed. For the G-Flex and G-Port features, SP
generally refers to an HLR. Also note that the terms MSISDN and DN are used interchangeably
throughout this document.
The ANSI-41 Mobile Number Portability (A-Port) feature supports mobile number portability in
ANSI-based networks. The ANSI-41 Mobile Number Portability feature uses the EAGLE Provisioning
Application Processor ( EPAP) provisioning database to retrieve the subscriber portability status and
provision directory numbers for exported and imported IS41 subscribers. The A-Port feature supports
both IS41 LOCREQ and SMSREQ messages for number portability handling. The A-Port feature uses
the MNP SCCP Service Selector to process GTT-routed LOCREQ and SMSREQ SCCP messages.
The IS41 GSM Migration feature refers to the movement of the subscribers of an ANSI IS-41MAP
protocol based network to a GSM MAP protocol based network while retaining their mobile telephone
numbers.
After migration, subscribers are able to:
• Use GPRS-based data services that are provided only by GSM networks.
• Enhance their roaming capability to a larger number of countries because GSM networks are more
widely deployed worldwide than IS41 networks.
The IS41 GSM Migration feature uses the G-Port MSISDN portability type (PT) field to identify
subscribers that have migrated from IGM to GSM, but maintain only a single GSM handset. This
category also includes new subscribers who sign up for GSM service only and have only one handset,
but are given a number from the existing IS41 number range. Since these subscribers are either migrated
(PT=5) or not migrated (PT=0), the new PT values do not logically overlap the existing values. PT
values are mutually exclusive of each other.
The ANSI-41 Number Portability Query (AINPQ) feature provides number portability in networks
that support a mix of ITU and ANSI protocols by allowing ANSI-41 NPREQ queries on the EAGLE 5
ISS database. INP uses the INAP TCAP protocol and AINPQ uses the ANSI-41 TCAP protocol for
Query functions.
The G-Flex feature allows mobile network operators to optimize the use of subscriber numbers (IMSIs
and MSISDNs) and number ranges by providing a logical link between any MSISDN and any IMSI.
This allows subscribers to be easily moved from one HLR to another. It also allows each HLR to be
filled to 100 percent capacity by allowing MSISDN/IMSI ranges to be split over different HLRs and
individual MSISDNs/IMSIs to be assigned to any HLR. G-Flex also eliminates the need to maintain
subscriber routing information at every MSC in the network.
