Soft Capacity Modeling for WCDMA Radio Resource Management
This work addresses wireless capacity models and capacity consumption models for 3G WCDMA system analysis. Uplink and downlink capacities are viewed as multiple heterogeneous circuit-switched and packetswitched pools of various bit rate channels, wherein traffic channels and control channels contend for the same capacity within a cell. An individual user’s consumption of capacity is formulated ...
متن کاملRadio resource management in WCDMA-based networks in emergency situations
The paper addresses a situation, when universal mobile telecommunication system (UMTS) network gets congested as a result of a catastrophe or an accident involving many people. The scenario of the situation and objectives for the network during the congestion are defined. Finally, two simple resource management algorithms useful in this case are compared. Their performance, when used separately...
متن کاملSUBRAMANIAM , KAMALA . Radio Resource Management in UMTS - WCDMA Systems
SUBRAMANIAM, KAMALA. Radio Resource Management in UMTS-WCDMA Systems. (Under the direction of Professor Arne A. Nilsson). Universal Mobile Telecommunications System (UMTS) is a Third Generation (3G) cellular technology representing an evolution of a heterogenous mix of services and increased data speeds from today’s second generation mobile networks. UMTS uses Wideband Code Division Multiple Ac...
متن کاملEconomic Modeling of Radio Resource Management: A Novel Metaheuristic Approach
In this paper we introduce a constrained hybrid PSO algorithm, called Improved Hybrid Particles Swarm Optimization (I-HPSO), in order to find feasible solutions to the problem of resource allocation in the downlink of a multi-cell WCDMA system. An economic model is developed that considers the utility of the provided service, the acceptance probability of the service by the users and the revenu...
متن کاملRadio resource management for public femtocell networks
With evolution and popularity of radio access technologies, the radio resource is becoming scarce. However, with fast-growing service demands, the future advanced wireless communication systems are expected to provide ubiquitous mobile broadband coverage to support higher data rate. Therefore, it is becoming an important problem that how to meet the greater demand with limited resources? In thi...
