Leading International Operator Deploys Comverse Real-Time Billing And SMS Solutions In Latin America.

NEW YORK -- Comverse, a unit of Comverse Technology, Inc. (NASDAQ: CMVT), and the world's leading supplier of software and systems enabling network-based multimedia enhanced communication services, today announced that Millicom International Cellular, a leading international operator of cellular telephony services, has implemented both Comverse's prepaid billing solution and SMS solution in five of its Latin American properties. Comverse is Millicom's Regional Partner, providing prepaid billing platforms in Bolivia, Guatemala, El Salvador, Honduras, and Paraguay, and also provides a bundled Intelligent Short Message Service Center (ISMSC) to manage Millicom's GSM overlays and existing TDMA and CDMA networks throughout Central America.

"With Latin America's prepaid subscriber base reaching almost 80 percent of total subscribers, the prepaid billing supplier plays a critical role within the business of mobile operators in the region. Much of the operator's marketing success directly depends on the power and agility of the billing solution," stated Javier Jimenez, Vice President and General Manager, Latin America at Comverse. "We are pleased to provide a "future-proof" solution that enables Millicom to charge for current voice and data services in real-time, as well as to introduce emerging data and content services as they become available in the future."

The Comverse Real-time Billing & Prepaid Solutions deliver dynamic control of telephony services and can manage many millions of active subscriber accounts simultaneously. The Comverse solutions can authorize, rate, charge and control voice calls, data sessions and emerging m-payment transactions in real-time. The built-in capability to impose real-time credit limits on accounts reduces the operator's risk when deploying new services. The Comverse solution is both flexible and reliable, operating with all major switch types and networks (GSM, GPRS, CDMA, and TDMA 2G, 2.5G, and 3G), and supports the latest standards, including CAMEL 2&3, WIN/IS-826 and OSA/parlay.

Comverse's ISMSC offers throughput of 2,500 messages per second, cost-saving connectivity options, and the ability to optimize system resources and delivery mechanisms to match the different kinds of SMS traffic in the network, such as person-to-person messaging, notification, push, Comverse Who Called and other applications. The ISMSC integrates into all major mobile network types. Moreover, its support for prepaid SMS allows mobile carriers to provide the same level of SMS service to both prepaid and contract subscribers. Comverse also offers a Dual Network SMSC, which provides seamless cross-network SMS messaging for carriers operating two different networks. Another valuable add-on to the ISMSC is the GSM Emulator Mobile Terminated Gateway for CDMA and TDMA networks. The GSM Emulator creates a seamless interface to the GSM network environment, enabling IS-41 subscribers to exchange messages with their GSM counterparts. The Comverse ISMSC is 2.5G and 3G compliant.
