Experiences of the live WCDMA network in Stockholm, Sweden
The joint Ericsson-Telia WCDMA evaluation project has provided valuable experience in terms of live system performance and general system operation and given early feedback and validated working assumptions for the ongoing development of the commercial third-generation system. |
Media gateway for mobile networks
Ericsson’s media gateways play an important role in the evolution toward the new, horizontally layered network architecture. Positioned in the connectivity layer at the crossing point between different networks, they are fully controlled from servers via the H.248 protocol. By introducing MSC and SGSN servers that work together with the media gateways, operators can migrate their networks toward the new architecture. |
Ericsson’s IP-based BSS and radio network server
The IP-based base station system is designed to support both GSM BSS and TDMA-EDGE radio access networks. Having been optimized to handle a mix of data (GPRS and EDGE) and real-time services, such as voice traffic, it provides a future-proof path to the GSM EDGE radio access network. |
Control servers in the core network
The horizontally layered architecture is playing a key role in the migration from earlier architectures into third-generation multiservice networks. A central element in the horizontally layered architecture is the network control layer, where control servers perform call and session control. |
Ronja—A Java application platform
The Ronja framework with high-availability/cluster software delivers standard telecommunications characteristics to applications that use commercial operating systems and hardware. Plug-and-play functionality, scalability, uninterrupted execution and failover can be transparently implemented in the applications using the high-level, high-availability library and templates provided in the framework. |
Wireless ad hoc networking—The art of networking without a network
Spontaneous, ad hoc wireless communication between devices—loosely defined as a scheme called ad hoc networking—allows devices to establish communication, anytime and anywhere without the aid of a central infrastructure. As novel technologies such as Bluetooth materialize, the scenario of ad hoc networking is likely to change. |
Ericsson’s WebOnAir Information Server
Ericsson’s WebOnAir Information Server opens up the world of accurate, convenient and timely information to operators, service providers and users, facilitating the integration of SMS, WAP, positioning, and personalization into value-added mobile services. |
