We present a simulation study covering the relation of service dynamics to the transfer and evaluation time of measured system state information in self organizing multi standard joint radio resource management (JRRM) systems. Architectures and algorithms based on network-initiated and mobile-initiated actions are compared. The used hybrid simulation and modeling framework allows for a cost-benefit...
Deployment of new radio technologies in the mobile world has not been more critical than it is now. The customers and applications have been starving for more data throughput while operators are struggling to deliver the promised high data rates to customers. Operators are using existing traffic information from GSM/GPRS technologies to deploy WCDMA and HSDPA systems. The deployment of WCDMA in the...
GSM/UMTS mobile networks deployed by operators are not static, but they are continuously evolving. They need periodic adjustments, expansion and optimization. Subscribers demand good quality in the services they use and pay for, as well as new innovative services that usually require higher speeds and bit rate. Being able to use an automatic optimization tool represents a major advantage for an operator,...
Increasing bandwidth demand from mobile Internet applications and the existence of 2G, 3G and soon 4G equipment in operators' networks forces them to implement an efficient resource management over all available radio access technologies. While such a multi-radio management will certainly improve resource utilization and allows reducing local hot spots, it comes at the cost of additional signaling...
This paper focuses on technology management's strategic integration practice for the broadband service sector. It evaluates the broadband market and in particular the wireless broadband (WBB) market of Pakistan. The paper discusses why Pakistan needs WBB more than fixed broadband (DSL, Cable). It identifies the TM (technology management) concerns (3G license cost, technology selection, WBB penetration...
In this paper, an innovative mechanism to perform joint radio resource management (JRRM) in the context of heterogeneous radio access networks is introduced. In particular, a fuzzy neural algorithm that is able to ensure certain quality-of-service (QoS) constraints in a multicell scenario deployment with three different radio access technologies (RATs), namely, the wireless local area network (WLAN),...
A power and rate control scheme especially crafted for delay tolerant traffic under interfering link conditions is presented in this paper. Specifically, an iterative distributed algorithm, based on a sum-power constrained sum-rate maximization with upper (and lower) power and rate constraints, is developed. The feasibility and performance of the algorithm is demonstrated by simulation in a cellular...
