HP Provides MetroPCS with OpenCall HLR product

PALO ALTO, Calif., May 8, 2006

HP today announced that MetroPCS, an innovative wireless carrier, is in the process of deploying the HP OpenCall Home Location Register (HLR) in the core of its all-digital network.

Based in Dallas, MetroPCS provides over two million customers in the greater Miami, San Francisco, Atlanta, Tampa, Sacramento, Dallas and Detroit areas with unlimited local and long distance calling, flat rate pricing and no required contract.

The HP OpenCall HLR functions as a central database that links individual information (identity, settings, status, authentication) with network routing information — so that each customer receives complete voice and data services while he or she is on the move.

"MetroPCS is committed to offering quality wireless service to our customers, and the HP OpenCall HLR will help us continue to provide those high levels of service," said Roger Linquist, president and CEO, MetroPCS.

HP OpenCall HLR is currently deployed by 36 operators on five continents, and handles mobility management for more than 200 million wireless customers. It runs on the HP NonStop server platform.

"MetroPCS' success reflects its willingness to innovate and its attention to customer needs," said Steve Dietch, director, worldwide marketing, HP OpenCall. "The HP OpenCall HLR will give MetroPCS a solid foundation for continued innovation and customer satisfaction."

To help operators deliver high quality, next generation voice and data services, HP has developed and certified an Internet Protocol (IP)-based successor to the HP OpenCall HLR, called the HP OpenCall Home Subscriber Server (HSS). Similar in function, the HP OpenCall HSS is designed for the emerging networks that utilize Internet Protocol Multimedia Subsystem (IMS) technologies.

The HP OpenCall HSS is the industry's first IMS standards-compliant mobility management solution. It provides mobility management for circuit-switched, packet-switched, and IMS-based networks, and can reduce costs by enabling central provisioning of the Home Location Register (HLR), new services and the HSS itself.

The HP OpenCall HLR and HSS are part of the broader HP OpenCall portfolio, a suite of standards-based, carrier-grade software platforms for developing and deploying next-generation voice, data and converged multimedia services.

The HP OpenCall products are delivered to service providers by the HP Network and Service Provider Business, as part of comprehensive solutions that include HP professional services and partner products.
