An optimum dynamic priority-based call admission control scheme for universal mobile telecommunications system

The dynamism associated with quality of service (QoS) requirement for traffic emanating from smarter end users devices founded on the internet of things (IoTs) drive, places a huge demand on modern telecommunication infrastructure. Most telecom networks, currently utilize robust call admission control (CAC) policies to ameliorate this challenge. However, the need for smarter CAC has becomes imperative owing to the sensitivity of traffic currently being supported. In this work, we developed a prioritized CAC algorithm for third Generation (3G) wireless cellular network. Based on the dynamic priority CAC (DP-CAC) model, we proposed an optimal dynamic priority CAC (ODP-CAC) scheme for Universal Mobile Telecommunication System (UMTS). We then carried out simulation under heavy traffic load while also exploiting renegotiation among different call traffic classes. Also, we introduced queuing techniques to enhance the new calls success probability while still maintaining a good handoff failure across the network. Results show that ODP-CAC provides an improved performance with regards to the probability of call drop for new calls, network load utilization and grade of service with average percentage value of 15.7%, 5.4% and 0.35% respectively

Communications Policy for 2006 and Beyond

In this Article, the Authors propose sweeping changes to the current telecommunications regulatory regime. With impending reform in telecommunications laws, the Authors argue that an important first step is the creation of a bipartisan, independent commission to examine and recommend implementation of more market-oriented communications policy. Through maximizing the operation of the markets, the authors argue that communications policy will better serve its goals of increasing business productivity and consumer welfare through the better services and lower prices. Important steps to achieve optimal market operation include deregulating retail prices where multifirm competition is available, minimizing the cost of public property inputs, overhauling universal service, assigning greater jurisdictional authority to federal regulators, and significantly reorganizing the FCC. The Authors argue that the timely implementation of these policies is crucial for achieving United States telecommunications policy goals
