Real-time performance monitoring and optimization of cellular systems
As cellular networks grow in size and complexity, the process of managing them becomes increasingly costly for mobile operators. For this reason, automated network management is very appealing.
IP technology in WCDMA/GSM core networks
Mobility and the Internet converge in the design and implementation of the Ericsson mobile core network. Support for new services and a common transport technology are the main drivers for the integration of IP technology into the core network.
The future of communication using SIP
SIP is a central part of the value proposition of future multimedia networks. SIP is flexible, supports a wide range of media types, communicates a wealth of information, and is readily integrated with Web-enabling technologies. Ericsson is developing several new products and solutions that will enable operators to position themselves in new markets and to realize new revenue streams.
Ericsson Mobile Operator WLAN solution
Wireless LAN is a complementary service offering for mobile operators. The Ericsson Mobile Operator WLAN solution combines the wide-area benefits of second- and third-generation mobile systems, including unlimited roaming and mobility, with greater throughput and capacity in indoor WLAN hot-spots.
