For 3G and beyond wideband code-division multiple access (WCDMA) cellular networks supporting heterogeneous traffic , sharing the radio access network has become an important issue for 3G mobile service providers (MSPs). Sharing of network infrastructure among MSPs offers an alternative solution to reducing the investment in the coverage phase of WCDMA. In radio access network (RAN) sharing method,...
Keeping up with modern high-speed networks is a significant challenge for network interface controller (NIC) designers. With the appearance of high-speed networks with link speed reaching ten gigabits per second, the network interfaces become the bottleneck of communication. System performance of Gigabit network hosts can severely be degraded due to interrupt overhead caused by heavy incoming traffic...
Multimedia applications over high-speed networks can generate heavy load conditions. When high-speed network end system is involved in processing the network traffic, its performance depends critically on how its tasks are scheduled. Therefore, the polices and mechanism that schedule incoming network traffic and other tasks should guarantee acceptable system throughput, reasonable latency and jitter,...
Sharing of 3G network infrastructure among operators offers an alternative solution to reducing the investment in the coverage phase of WCDMA. For radio access network (RAN) sharing method each operator has its own core network and only the RAN is shared. Without an efficient RRM, one operator can exhausts the capacity of others. This paper proposes and analyzes an efficient uplink-scheduling scheme...
The wide-band code division multiple access (WCDMA) based 3G and beyond cellular mobile wireless networks are expected to provide a diverse range of multimedia services to mobile users with guaranteed quality of service (QoS). The main contribution of this paper is to design and analyze a novel dynamic priority call admission control (DP-CAC) that can be able to achieve a better balance between system...
Packet reservation multiple access (PRMA) can be considered as a merge of slotted ALOHA protocol and time division multiple access (TDMA) protocol. Independent terminals transmit packets to base station by contending to access an available time slots. A terminal that succeeds in reserving a certain time slot keeps on this reservation for transmitting its subsequent packets. Speech activity detection...
In current and next 3G and beyond mobile wireless systems, sharing the radio access network has become an important issue for 3G mobile operators. Sharing network infrastructure amongst operators offers an alternative solution to reduce the investment in the coverage phase of WCDMA, allows increased coverage, reduces time to market, and allows earlier user acceptance for WCDMA and its related services...
The wide-band code division multiple access (WCDMA) based 3G and beyond cellular mobile wireless networks are expected to provide a diverse range of multimedia services to mobile users with guaranteed quality of service (QoS). Soft capacity is one of the main characteristics of these networks and it necessitates new radio resource management strategies to serve diverse quality of service requirements...
This paper gives an overview of the network sharing options available for 3G and beyond network operators. Sharing of network infrastructure among operators offers an alternative solution to reduce the investment in the coverage phase of WCDMA, allows increased coverage, reduces time to market, and allows earlier user acceptance for WCDMA and its related services. Furthermore, in this paper general...
