significantly in Latin America in the coming years, strong growth is expected in
fixed network operations as well", notes Oscar Fernandez, Managing Director of
Tecnomen Latin America. He continues, "In addition, due to the high growth in
data traffic, it is strategically important that operators can charge for a
variety of data services using the same platform."

The Tecnomen Convergent Charging solution provides functionality for prepaid and
post-paid billing, charging and rating of voice calls, video calls, raw data
traffic and any kind of content services in both mobile and fixed networks. The
Charging solution has been pre-integrated with network equipment from leading

Utilising the modular Tecnomen Messaging solution, operators and service
providers are able to build messaging service packages tailored to suit their

value services required to succeed in today's competitive market.
