E 911 Service for a leading Location-based
Service Provider
The customer
The Client
is a developer of Wireless Location Service
software suite which allows mobile operators
to provide location-based services to their
subscribers
They had recently
acquired a leading company involved in the
development and operation of consumer applications
and technical solutions for mobile location-based
services, and thus expanded their applications
portfolio
The challenge
Provide support for a new type of PSAP (Public
Safety Answering Point) protocol without an ALI
(Automatic Location Identifier) database for their
Emergency service product W911.
The solution
Wipro
developed a software subsystem that would
interact with W911 and PSAP.
The solution
was developed using C++ in Tandem NSK environment
It encompasses
the software and map location data that is
required to route a Wireless 9-1-1 call to
the appropriate selective router or PSAP
W911 analyzes
the location information (cell/sector) provided
in the SS7 signal message when a caller dials
9-1-1 and provides a routing number or the
Emergency Service Routing Key (ESRK) to the
serving wireless switch or MSC.
The solution
catered to the needs of scalability, availability
& reliability features required in this
Life-Saving Usage Scenario.
The benefits
Time-to-market
- Implementation time - 3 months
Flexible
architecture where sizing of each module can
be decided individually
Expertise
in Architecting and Performance Tuning were
directly available to client
The customer
greatly benefited from the simulator development
as it provided superior capabilities for field
testing.
