Power control in UMTS Release '99
The CDMA technology used in UMTS relies on accurate power control techniques, not only for maximising the battery life of mobile terminals and maintaining signal quality, but also as an important means of optimising system capacity by contr...
Numbering, naming and addressing for third generation mobile communications
The third generation (3G) of mobile communications is approaching fast and networks based on 3G technology will be operational in the next few years in the major European countries. They will inherit system characteristics both from traditi...
Secure interoperation between 2G and 3G mobile radio networks
Interoperation of 2G and 3G networks will be an important issue when both kinds of networks will exist in parallel and need to interwork with each other. Among other things, this implies that 2G subscribers should be able to access 3G netwo...
Strategic aspects of core network migration
The problem every potential 3G operator has to face today is how to either migrate to or build from scratch the new networks that will offer new data services and applications to mobile subscribers. There are currently two different core ne...
Migration to all-IP based UMTS networks
There has been a significantly increased interest in building future UMTS systems based on IP (Internet protocol) technologies. The major motivation is to have a common service platform and transport for 3G networks based on IP. This is als...
Experiences of Ericsson's WCDMA evaluation system in the UK
Ericsson has developed the WCDMA based evaluation system to demonstrate the potential of the 3/sup rd/ generation (3G) mobile communications. It has been intended for field deployments on a limited scale in different parts of the world. In ...
Integration of experimentally measured propagation data into system simulations
The current interest in the development of third generation cellular radio systems has focused attention on propagation channel issues. CDMA systems occupy wide bandwidths, which typically exceed the channel coherence bandwidth, leading to ...
Orange/Fujitsu wideband CDMA field trials-system overview
Around the globe operators and manufacturers are rapidly preparing for the deployment of third generation systems. With some operators aiming for commercial deployment as early as 2001, field trials of third generation systems are currently...
Experiences with the WCDMA network in Stockholm, Sweden. A venture between Telia and Ericsson
Telia and Ericsson have executed a joint project to evaluate the Ericsson WCDMA experimental system in Stockholm, Sweden. This system has been an important tool for gaining valuable hands-on WCDMA experience and to support the development o...
