Data plane performance issues concerning MBMS in UMTS Release 6
Conference Paper
  • May 2005
Third generation (3G) wireless networks, such as UMTS, should offer broadband broadcast and multicast services enabling several mobile users to receive the same downlink data stream using minimum possible network resources. It appeared that CBS (Cell Broadcast Service), used in current 2G and 3G networks, is insufficient to provide such services in...

On performance of MAC-c/sh in UMTS
Conference Paper
  • Feb 2004
MAC (medium access control) is one of the sublayers of layer 2 of the radio interface protocol stack in UMTS. MAC-c/sh is a part of MAC responsible for handling data transported on common and shared transport channels. The goal of this paper is to analyse the performance of MAC-c/sh, with focus on the MAC-c/sh FACH scheduler and the FACH flow contr...

Analysis of profitability of inter-system handovers between IEEE 802.11b and UMTS
Conference Paper
  • Nov 2003
Internet access using relatively fast wireless local area networks (WLANs) is often perceived as a local complement to slower, but widely available access using cellular networks, e.g. GSM/GPRS or UMTS. To benefit from the advantages offered by both radio access networks, a mobile user should be able to seamlessly change the access network while mo...

Article
Full-text available
Mobile Internet access is currently available mainly using 2G/3G cellular telecommunication networks and wire-less local area networks. WLANs are perceived as a local complement to slower, but widely available cellular networks, such as existing GSM/GPRS or future UMTS networks. To benefit from the advantages offered by both radio access net-works,...
