communication across the network to all
wireless service nodes. ALR for HLRs supports
a significantly better usage of HLR capacity and
allows a separation of the mobile identification
number (MIN) from the mobile directory number
(MDN). In addition, with ALR for SMSCs and ALR
for VMSs, the Alcatel 5070 SSG ANSI can provide
Flexible Routing to SMSCs and voice mail/unified
messaging systems, respectively. This enables
new services on dedicated nodes for a particular
group of subscribers.
ALR routing uses a specialized database, coupled
with software to decode fields in the SCCP and
TCAP portions of the signaling message, to
identify the subscriber and translate the network
address of the node handling a subscriber’s
service, such as the HLR. ALR routing enables
the Alcatel 5070 SSG ANSI to respond to queries
for updating subscriber location, sending routing
information or forwarding short messages. The
ALR implementation supports IS-41 as well
as GSM-based networks.
An interface to external provisioning systems
handles transactions for activating subscriber
records and establishing HLR, SMSC and
other subscriber routing information.
