STOCKHOLM -- Ericsson has been selected by Telefónica to provide Ericsson's IP Multimedia Subsystem (IMS) solution. The solution will allow Telefónica to offer its fixed network customers various services including IP telephony and IP Centrex to business users. The implementation will start during the spring.

Ericsson's IP Multimedia Subsystem (IMS) gives operators an immediate revenue opportunity when evolving to all-IP operations, through a wide range of new or enriched services, and where service enablers for common functions can be reused for multiple fixed and mobile applications.

The IMS based IP Centrex functionality hosts a complete set of personal and group services, with the addition of multimedia support such as video telephony, conference calling, sharing of documents and web pages (collaboration), presence management, instant messaging, e-mail integration and support for remote workers. This will offer an important enhancement to Telefonica's portfolio using a broad range of interoperable terminals.

"IMS is the foundation for an enhanced communications experience and a range of applications, which will provide additional revenue streams to the operators. At the same time, there are clear cost benefits of having one IMS solution supporting multiple applications," says Ingemar Naeve, Head of Market Unit Iberia, Ericsson. "We are proud to be able to share with Telefonica our vast knowledge from working with IMS both from a standardization and development point of view."
