Managing radio network congestion in UTRA-FDD

摘要

The presence of different service classes in the context of 3G mobile communication systems opens up new possibilities to exploit the spectrum in an efficient way. In the search of such a high efficiency, radio network congestion may arise and it is mandatory to include suitable algorithms to deal with these situations. Here, congestion control mechanisms in the radio interface of UTRA FDD are proposed and analysed. Results show that under congestion it seems more suitable to adopt firm and strict rate control decisions rather than softer policies.
