NeuStar Launches Analytical Service for Mobile Operators

"NeuStar Subscriber Growth Service" projected to help mobile operators drive a
strong increase in IM subscriber bases

LONDON, June 24 /PRNewswire-FirstCall/ -- NeuStar (NYSE: NSR) today unveiled
the NeuStar Subscriber Growth Service and its corresponding Best Practice
Guidelines, which are designed to enable participating mobile operators to
increase their mobile Instant Messaging (IM) subscriber uptake by up to 40%
every year.

The Subscriber Growth Service has been created to help participating operators
improve existing mobile IM services considerably and capitalise on the huge
market for mobile IM, which grew by 83.3% in 2008 in Western Europe.(1)
Operators who adopt the Subscriber Growth Service will work with NeuStar's
Strategic Services team throughout the process of launching, marketing, and
running an IM service, and will receive consultancy on how to build successful
new IP business models based on NeuStar's track record of increasing the level
of subscriber uptake.

With access to the only database of real-time subscriber IM behaviour on the
market, NeuStar is able to tap into each operator's subscriber base to break
down which users are engaging with mobile IM, which handsets they use, how
regularly they communicate via IM, and how much they spend, and help the
operator use this information to optimise the service. By analysing each of
the mobile IM services that it has launched since 1999, NeuStar has created
the market's first Best Practice Guidelines and Key Performance Indicators
(KPIs) with the aim of supporting operators to effectively launch, market, and
drive additional IM services to their subscriber base.

Guenter Krauss, senior vice president and general manager of NeuStar Next
Generation Messaging (NGM) said of the launch: "With the Subscriber Growth
Service, we can work hand-in-hand with our customers, providing a
consultative, analytical service tailored to their market that will deliver
long-term business benefits and allow operators the privileged, granular view
of subscriber experience they need to increase uptake and profitability. We
believe that we can increase an operator's IM subscriber base and help them to
generate incremental revenues from compelling next generation messaging
services."

Building on NeuStar's established relationships with operators worldwide, the
Subscriber Growth Service will help participating operators to substantially
grow their existing subscriber bases, and will advise them on the best
handsets and price plans, customer lifecycle management and user experience
throughout the lifecycle of the service. With only 19.2% of mobile IM users
aged between 18 and 24 years old (2), and 20.3% of mobile IM users aged
between 35 and 44 years old (3), NeuStar has the internal data and real-time
analysis capabilities to advise operators how to effectively launch and market
a range of IM services to affluent age groups beyond the youth segment. By
harnessing this data and analysing IM activity on a daily basis, NeuStar
customers will be able to develop a loyal base of mobile IM users and also
pave the way for new presence-enabled services.

"We have discovered, for example, that the use of mobile clients is growing
more rapidly than the use of browsers to deliver IM - and in many instances,
users actually prefer accessing IM via a downloadable client because it gives
a better user experience," Krauss said of NeuStar's analytical capabilities.
"It is this type of data that we will feed back to our customers to help them
develop the very best IM services, drive subscriber uptake and ultimately
increase retention."
