Congestion Aware

With the recently progress of Machine-to-Machine (M2M) communication technology, especially the enormous M2M devices and unique service of M2M, some challenges are emerging to the traditional wireless access and core networks, especially the congestion problem due to simultaneously bursty M2M service. Following this paradigm, the purpose of this paper is to support and optimize the signaling aggregation and barring of M2M services based on cellular network. With LTE network being the example access network, a congestion-aware signaling aggregation and barring scheme is designed considering the various requirements of M2M services and the congestion situation in the network entity. Theoretical analysis and experimental simulations show that this scheme can improve the system efficiency and greatly alleviate the signaling congestion, especially for the bursty M2M service.

Minimal Cost Flow

With the explosive growth of wireless applications, the subscribers’ requirements of QoS (Quality of Service) are increasing as well. In this paper, the upper bound of the tolerant delay of services in wireless access network is investigated, by mapping core network onto a cost-variable directed graph, where the cost is construed as the average service delay of the flows traveling in core network that depends on the current load. A multicommodity minimal cost flow mathematics problem is then derived and solved by Price-directive Decomposition and Lagrangian Relaxation. Simulations are carried out in two typical core networks and some valuable conclusions are gained.

Data Rates

Access networks are usually termed “last-mile/first-mile” networks since they connect the end user with the metro-edge network (or the exchange). This connectivity is often at data rates that are significantly slower than the data rates available at metro and core networks. Metro networks span large cities and core networks connect cities or bigger regions together by forming a backbone network on which traffic from an entire city is transported. With the industry achieving up to 400 Gbps of data rates at core networks (and increasing those rates [Reading, 2013]), it is critical to have high-speed access networks that can cope with the tremendous bandwidth opportunity and not act as a bottleneck. The opportunity lies in enabling services that can be of benefit to the consumers as well as large organizations. For instance, moving institutional/personal data to the cloud will require a high-speed access network that can overcome delays incurred during upload and download of information. Cloud-based services, such as computing and storage services are further enhanced with the availability of such high-speed access networks. Access networks have evolved over time and the industry is constantly looking for ways to improve their capacity. Therefore, an understanding of the fundamental technologies involved in wired and wireless access networks will help the reader appreciate the full potential of the cloud and cloud access. Against the same backdrop, this chapter aims at providing an understanding of the evolution of access technologies that enable the tremendous mobility potential of cloud-based services in the contemporary cloud paradigm.

Gagasan dibalik SRAN (Single Radio Access Network) sangat sederhana yaitu dapat mengoperasikan berbagai teknologi radio pada satu platform hardware multiguna. Dalam bentuk pengembangan terbaru, SRAN terdiri dari satu instalasi radio dengan common transport dan sistem operasional dan manajemen dengan keamanan terpadu di seluruh RATs (Radio Access Technologies). Selain itu, SRAN dapat mengoordinasikan dan mengoperasikan berbagai RAT secara terpadu serta mampu menggunakan RAT yang ada untuk menghasilkan kinerja terbaik dengan mengoordinasikan keuntungan masing-masing RAT. Modularitas adalah enabler utama yang meningkatkan kapasitas sesuai dengan permintaan dan spektrum baru dan spektrum yang ada dapat digunakan lebih efisien. Sumatra Utara – site DRDTOBINJAI2 adalah lokasi yang dipilih untuk dimodernisasi dengan solusi SRAN. Hasil implementasi pada site tersebut setelah diuji dan dianalisa, SRAN dapat menyederhanakan penggunaan hardware dari 5 modul sistem dan 5 modul transmisi menjadi 3 modul sistem dan 2 modul transmisi dengan menambahkan teknologi LTE di band 900 dan 2100 pada site tersebut. Efisiensi pada operasional meningkat melalui network sharing, efisiensi energi jaringan radio meningkat sekitar 27% dan software dapat digunakan untuk menentukan fungsi hardware agar lebih fleksibel, performa lebih baik dan meningkatkan efektifitas biaya. Dengan melakukan drive test, SRAN terbukti meningkatkan throughput pada uplink hingga 10 Mbps dan mengurangi waktu delay dari >70 ms menjadi 40 ms.

Network Sharing

Purpose 5G systems will enable an improved transmission performance and the delivery of advanced communication services. To meet the expected requirements, operators will need to invest in network modernisation, with the radio access network being the most expensive network component. One possible way for operators to reduce this investment would be via sharing of resources by means of a multi-tenancy concept. This implies that a mobile service provider may use the common infrastructure of one or various infrastructure providers, whereby it provides services to multiple tenants. This paper aims to study the expected cost savings in terms of capital expenditures (CAPEX) and operational expenditures (OPEX) that can be achieved when using a cloudified 5G multi-tenant network. Design/methodology/approach A cost model was used. The study period is 2020-2030 and the study area consists of three local districts in central London, UK. Findings This paper describes that the total cost reduction achieved when using multi-tenancy for a 5G broadband network in comparison with the case where operators make the investment independently ranges from 5.2% to 15.5%. Research limitations/implications Further research is needed to assess the cost implications of network sharing for 5G on a regional or nationwide basis. Originality/value Very little quantitative research about the cost implications of network sharing under 5G networks has been published so far. This paper sheds light on the economic benefits of multi-tenancy in a 5G broadband network.

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 a 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.
