EVOLUTION TO 3G SERVICES: PROVISION OF 3G SERVICES OVER GERAN (GSM/EDGE RADIO ACCESS NETWORK)

摘要

With the drive for 3G network rollout being tempered by the realities of the current economic climate, 3G will initially be deployed in islands, with GSM/GPRS/EDGE providing coverage in between, hence the nationwide provision of 3G services such as video/audio streaming must rely on the evolution of current 2.5G technologies to meet the expected service requirements. Within TSG GERAN, work has been ongoing for a number of years in order to meet the QoS criteria required for 3G services within 3GPP, and this paper provides an insight into the benefits and problems of competing solutions. The first 3G systems are being installed as we speak, and coverage maps are showing that there are significant areas of the UK where some 3G services will not be supported. Thus, a mechanism must be provided for the future that allows operators with combined 2.5G and 3G networks to be able to provide common services regardless of the users location.
