Mobile operators are moving towards sharing network capacity in order to reduce capital and operational expenditures, while meeting the increasing demand for mobile broadband data services. Radio access network sharing is a promising technique that leads to reduced number of physical base station deployments (required for coverage enhancement), increased base station utilization, and reduced overall...
Much work has been conducted to design effective and efficient algorithms for Quality of Service (QoS)-aware service selection algorithms in recent years. The wireless mobile computing and cloud computing environments have brought many challenges to QoS-aware service selection. Device-to-Device (D2D) communication and Cloud Radio Accessing Networks (C-RAN) are the new paradigm arising in recent years...
The demand for rich multimedia services over mobile networks has been soaring at a tremendous pace over recent years. However, the wireless link capacity as well as the bandwidth of the radio access networks and the backhaul network cannot practically cope with the explosive growth in mobile traffic load. In this article, we mainly focus on a new novel framework of cooperative cell caching for future...
With the development of Mobile Internet and the rapid growth of mobile social communication and mobile video, the network scale has been growing rapidly and the energy consumption is too huge to be ignored. Current estimates indicate that Information and Communication Technology (ICT) is responsible for a fraction of the global energy consumption ranging between 1% and 2%, among which, the consumption...
The global demand for mobile-broadband data services has experienced phenomenal growth over the last few years, driven by the rapid proliferation of smart devices such as smartphones and tablets. This growth is expected to continue unabated as mobile data traffic is predicted to grow anywhere from 20 to 50 times over the next 5 years. Exacerbating the problem is that such unprecedented surge in smartphones...
Mobile infrastructure and in particular radio access network (RAN) sharing is becoming an important topic that mobile network operators are evaluating and considering in their expansion plans and investments decision. The arguments for network sharing are well known. It can substantially reduce CAPEX and OPEX, potentially increase the speed of network rollouts, improve coverage and help meet the capacity...
In most service provider networks today, performance enhancing proxies (PEPs), or optimization platforms, are used to improve performance through content caching, compression, application acceleration etc. PEPs are commonly deployed in wireline network ISPs and mobile networks between the core and Internet access point. This paper describes an alternative approach, which is to deploy content caches...
Availability of modern, reliable and offering a wide range of services wireless communication systems is crucial for the effective operation of Public Protection and Disaster Relief (PPDR) agencies during the emergency situations. This paper presents the elements of the financial-economic analysis for acquiring and operating PPDR communication systems by the interested entities. It deals with business...
This paper proposes a model for the management of virtual radio resources. The virtualisation of radio resources is based on aggregating and managing all the available physical radio resources in a set of infrastructures. In this approach, Virtual Network Operators (VNOs) use wireless connectivity in the form of capacity per service, and do not have to deal with physical radio resources at all. Due...
The mobile network plays an important role in the evolution of humanity and society. However, due to the increase of users as well as of mobile applications, the current mobile network architecture faces many challenges. In this paper we describe V-Core, a new architecture for the mobile packet core network which is based on Software Defined Networking and Network Function Virtualization. Then, we...
Mobile services are evolving rapidly, moving from their conventional mobile voice to a wider portfolio such as Internet access, entertainment, health, and also location-based services. A wide range of on-board mobile services with very different requirements is also offered by automotive manufacturers. They rely on Mobile Network Operators (MNOs) to offer the expected connectivity and QoS in markets...
The vital trend inside wireless networks is the heterogeneity of access technology. Vertical handover management is one of key challenges in such environment to ensure seamless mobility and service continuity especially in the case of network mobility. To deal with some of these challenges, numerous efforts were made in the context of standards and scientific research to perform the vertical handover...
Machine-type-Communication (MTC) is seen as a major service in next generation cellular mobile networks. However, the forecasted very large number of MTC devices may overload the RAN (Radio Access Network) part of the network, which may impact Non-MTC communications. Group paging is considered as one of the most efficient mechanisms proposed to alleviate the problem of the RAN overload. In this paper,...
This paper describes a device triggering optimization technique for controlling system overload when deploying massive Machine Type Communication (MTC) devices in 3GPP-based cellular networks. Triggering a large number of MTC devices can dramatically overload the underlying transport network system and incur congestion in both the Radio Access Network (RAN) and the Evolved Packet Core (EPC). The proposed...
Past years have witnessed the surge of mobile broadband Internet traffic due to the broad adoption of a number of major technical advances in new wireless technologies and consumer electronics. In this respect, mobile networks have greatly increased their availability to meet the exponentially growing capacity demand of modern mobile applications and services. The upcoming scenario in the near future...
Virtualisation of cellular networks can be seen as a way to significantly reduce the complexity of processes, required nowadays to provide reliable cellular networks. The Future Communication Architecture for Mobile Cloud Services: Mobile Cloud Networking (MCN) is a EU FP7 Large-scale Integrating Project (IP) funded by the European Commission that is focusing on how cloud computing and network function...
The 4G wireless network is proposed to integrate various radio access technologies into a common network known as open wireless architecture (OWA), this has led to the idea of cooperative user location estimation, in this paper we have proposed a cooperative TDoA/RSS/TDoA user location estimation method which uses information from two different Radio Access Networks (RANs) as the long range (LR) data...
Whilst Machine Type Communication (MTC) represents an important business opportunity for mobile operators, mobile operators fear the congestion that could come with the deployment of billions/trillions of MTC devices. In this paper, we present a new mechanism that anticipates system overload due to MTC signaling messages in 3GPP networks. This mechanism proactively avoids system congestion by compacting...
As mobile networks are witnessing huge growth in the volumes of data traffic from smartphone and tablet. Mobile operators start to look into CDN and caching in order to offload increasingly overloaded mobile networks, reduce network and peering cost, and improve mobile user's quality of experience. For CDN and cache deployment in mobile network, one practical issue is where to deploy CDN or cache...
Next generation wireless networks are expected to be Heterogeneous consisting of several wireless technologies such as 3G, WLAN, WiMAX, LTE etc. Users of future mobile networks will be able to choose from different radio access technologies. These networks vary widely in service capabilities such as coverage area, bandwidth and error characteristics. Network selection is a challenging task in heterogeneous...
