As 3G networks are very widely deployed, there exists increased capacity requirement and transport channel allocation to simultaneous users under a particular cell. Due to this reason, adequate resources are not available, which in turn degrades both service quality and user experienced quality. This research aims at understanding the characteristics of buffer filling during dedicated channel (DCH) transmission under fixed bit-rate assumptions on a per-user level taking different services into consideration. Furthermore, the resource utilisation in terms of empty buffer durations and user throughput achieved during dedicated channel transmission are also analysed for different data services existing in the mobile networks. -
A Novel View on Universal Mobile Telecommunication System (UMTS) in the Wireless and Mobile Communication Environment
Georgian Electronic Scientific Journal: Computer Science and Telecommunications 2010|No.1(24) A Novel View on Universal Mobile Telecommunication System (UMTS) in the Wireless and Mobile Communication Environment Dr.S.S.Riaz Ahamed Principal, Sathak Institute of Technology, Ramanathapuram,TamilNadu, India-623501. Email:[email protected] Abstract The Universal Mobile Telecommunication System (UMTS) is a third generation (3G) mobile communications system that provides a range of broadband services to the world of wireless and mobile communications. The UMTS delivers low-cost, mobile communications at data rates of up to 2 Mbps. It preserves the global roaming capability of second generation GSM/GPRS networks and provides new enhanced capabilities. The UMTS is designed to deliver pictures, graphics, video communications, and other multimedia information, as well as voice and data, to mobile wireless subscribers. UMTS also addresses the growing demand of mobile and Internet applications for new capacity in the overcrowded mobile communications sky. The new network increases transmission speed to 2 Mbps per mobile user and establishes a global roaming standard. UMTS allows many more applications to be introduced to a worldwide base of users and provides a vital link between today’s multiple GSM systems and the ultimate single worldwide standard for all mobile telecommunications, International Mobile Telecommunications–2000 (IMT–2000).

Evolution of Access Network Sharing and Its Role in 5G Networks
applied sciences Review Evolution of Access Network Sharing and Its Role in 5G Networks Nima Afraz * , Frank Slyne , Harleen Gill and Marco Ruffini * CONNECT Centre, Trinity College, The University of Dublin, 2 Dublin, Ireland; [email protected] (F.S.); [email protected] (H.G.) * Correspondence: [email protected] (N.A.); marco.ruffi[email protected] (M.R.) Received: 3 October 2019; Accepted: 18 October 2019; Published: 28 October 2019 Abstract: This paper details the evolution of access network sharing models from legacy DSL to the most recent fibre-based technology and the main challenges faced from technical and business perspectives. We first give an overview of existing access sharing models, that span physical local loop unbundling and virtual unbundled local access. We then describe different types of optical access technologies and highlight how they support network sharing. Next, we examine how the concept of SDN and network virtualization has been pivotal in enabling the idea of “true multi-tenancy”, through the use of programmability, flexible architecture and resource isolation. We give examples of recent developments of cloud central office and OLT virtualization. Finally, we provide an insight into the role that novel business models, such as blockchain and smart contract technology, could play in 5G networks. We discuss how these might evolve, to provide flexibility and dynamic operations that are needed in the data and control planes. Keywords: access networks; network sharing; 5G networks; multi tenancy; optical access; sharing economics 1. Introduction By its nature, a telecommunications network is a shared resource that interconnects multiple nodes. Network sharing is part of a fundamental principle of statistical multiplexing of link capacity. -

The requested declaratory ruling would be technology-neutral as it would provide licensees in the ESMR band with the ability to deploy and operate the mobile wireless technology of their choice, including 3G technologies such as CDMA and 4G technologies such as LTE. 1 / “Wireless Telecommunications Bureau Seeks Comment on Petition From Sprint Nextel to Allow Wideband Operations In 800 MHz Enhanced Specialized Mobile Radio Service Bands, WT Docket No. 11-110, Public Notice, DA 11-1152 (rel. June 30, 2011) (“Public Notice”). Significantly, the requested ruling would promote regulatory parity among CMRS providers and encourage the competitive deployment and greater availability of mobile broadband technologies and services for US consumers. SouthernLINC Wireless emphasizes, however, that the requested ruling must expressly apply to all EA-licensed ESMR frequencies, including those in the expanded ESMR band in the southeastern United States – i.e., the 813.5-824/858.5-869 MHz band. -
