SANTA CLARA, Calif.--(BUSINESS WIRE)--March 5, 2001

XACCT Technologies, the leading provider of business infrastructure software solutions for IP networks, today announced XACCTmobile(TM), a software solution that enables and accelerates the roll-out of value-based wireless data services and mobile commerce (m-commerce) across wireless networks. Major mobile operators on three continents have already deployed the XACCTmobile solution -- including the world's first 3G UMTS (Third-Generation Universal Mobile Telecommunications System) deployment with British Telecom's Manx subsidiary. Given the enormous capital global telecommunications providers have spent over the past year on wireless spectrum licenses and infrastructure, the XACCTmobile solution provides them with a strategic tool to accelerate their ROI.

"XACCT has taken their market-leading N2B platform and enhanced it to specifically address the critical needs of mobile data service providers who are looking to offer profitable services and maximize revenue per subscriber," said Jennifer Liscom, Principal Analyst at Gartner. "Mobile operators know that they cannot recover their huge licensing costs through voice services alone -- they need to offer profitable mobile data services that are enabled by XACCTmobile."

XACCTmobile provides a real-time link between the physical network and the back-office infrastructure and enables carriers to understand how their mobile network is being used; they can translate this knowledge into new services and revenue. XACCTmobile is built upon XACCT's real-time "Network-to-Business" (N2BTM) platform -- the market-leading platform that is currently in production with over 60 customers around the globe. XACCTmobile allows mobile operators to understand network and service usage at the individual customer level -- allowing operators to create customized, value-based mobile services, thereby maximizing revenue and profit per subscriber.

"Our mission is to make data services profitable, and this includes data services for the mobile world," said Eric Gries, president and chief executive officer at XACCT. "Current duration/distance-based pricing models are not viable for achieving profitability in the new, always-on mobile network environment. Mobile service providers need to develop other more innovative ways of offering value to their customers. XACCTmobile provides them with unprecedented business intelligence and enables them to strengthen their service offerings and bottom line."

XACCTmobile Deployed in World's First 3G Network

XACCTmobile is deployed in the world's first UMTS network -- the third generation of mobile telecom services -- on the Isle of Man, in the center of the British Isles. BT Manx, a telecommunications subsidiary of British Telecom, needed a new solution for a wireless network offering high-speed data-transmission capabilities, including fast Internet access and potential services (such as full-motion video and music downloads). BT Manx selected XACCTmobile to collate data on usage, content type, and rate of transmission. The BT Manx deployment -- and the data it generates -- is being watched closely around the world as a "test-bed" for future 3G networks.

XACCTmobile Solution Addresses Needs of Mobile Service Providers

XACCTmobile is a software solution targeted specifically at mobile service providers. It combines multi-source, multi-layer data collection and enhancement, providing the most comprehensive and granular data from the network and synthesizing this data into actionable business information. Developed working with the world's leading mobile providers, XACCTmobile supports all 3GPP mobile standards and offers mobile operators these benefits:

-- Allows mobile operators to understand their network and service usage to
create value-based, high-margin services based on the data it captures and
synthesizes.

-- Provides concurrent real-time feeds to multiple downstream business and
operational applications (both customer-facing and network-facing).

-- Speeds time-to-revenue for new services and applications. XACCTmobile is
engineered for performance and scalability via a highly distributed modular
architecture.

-- Eases deployment costs with flexible pricing and packaging that scales as
subscribers/mobile networks grow.

-- Incorporates the carrier-class reliability of XACCT's N2B platform, which
has already been proven with over 60 major customers globally.

XACCTmobile allows operators to capture and transform raw network usage data from General Packet Radio Spectrum (GPRS), UMTS, cdma2000, and IP networks into actionable business information needed for service creation, billing, marketing, churn reduction, fraud prevention, service level verification, capacity planning, and customer relationship management. This information gives mobile operators an advantage in developing new services and maximizing revenue and profit.

XACCTmobile captures session and transaction information from the Public Land Mobile Network (PLMN) or Packet Core Network (PCN), Wireless Application Protocol (WAP) gateways, and the entire IP network using multi-purpose and device-specific software modules called Information Source Modules (ISMs). Captured information is enhanced with data from IP network and service elements such as routers, switches, firewalls, probes, remote access servers, DNS servers, and more. By collecting and synthesizing information from multiple sources and metering multiple parameters -- including Quality of Service (QoS), bandwidth used, volume, user-ID, duration, mobile location information, and launched applications -- XACCTmobile can transform and correlate data into a detailed picture of network usage and understanding that directly translates into new services and revenue.
