The Current Telecom Industry faces a steady competition of providing new technologies to its customers and to meet the challenges of the up-gradation of the existing technologies. The more the number of operators, the more is the need for spectrum resources as well as new infrastructure keeping in mind the scarce resources available. This report provides a technical analysis of how 3rd Generation...
In this paper, we propose a new architecture for LTE/EPC network by leveraging the Openflow technology. We focus on making detail procedures for initial attach and default bearer setup in Openflow-enabled LTE/EPC network. By numerical analysis, we show the reduction of the signaling load of this procedure in our architecture compared to that in the traditional LTE/EPC architecture.
WebRTC, browser-to-browser communication technology, has on short term a desktop strategy, which will unleash its potential in 2013/2014. It is a great opportunity for Telco's to achieve a promise of service continuity for the RCS standard. But general disintermediation patterns and WebRTC going mobile and being an API of its own, are a serious mid-term challenge for operators.
Key incentives for mobile operators to offer femtocell services are the possibilities to cost-efficiently enhance indoor coverage and to offload traffic from the macro-cellular network. While femtocells were originally conceived for standalone deployments in user homes, there is an increasing interest in exploiting their advantages also in an enterprise context. However, with the current architecture...
Mobile social applications that allow users to share presence, opinions and recommendations about places are spreading rapidly. Among these, check-in applications are becoming increasingly popular, but present some issues. In this paper we illustrate a system to exploit user's context to perform automatic check-in validation and suggestion. A description of the system architecture and its technical...
Along the growth of internet traffic, the penetration of internet access from mobile user has been increased. By augmenting mobile data traffic, the mobile network capacity limits have become significant issues. To cope with the increased mobile user data to cellular radio networks, several offload approaches such as femtocells have been proposed. With regard to 3G core network offload, Selected IP...
Telecom based service providers are relentlessly trying to accelerate their service offerings to match the pace at which the users are embracing the Web. In reality IMS based Telecom and Internet based Web 2.0 networks have their own advantages and need to co-exist to create an enriched user experience. The convergence of IP Multimedia subsystem (IMS) based Telecom and Web 2.0 based networks is slowly...
A challenge in the convergence of heterogeneous networks is how to combine the ubiquitous resources and provide the diversified individual services. By this, the vision of adaptive and context-aware service provision becomes possible and offers new opportunities for pervasive computing. In this paper, we describe an approach that addresses the convergence of wireless personal area and wide area networks...
Increasing demand for mobile data communications and for various applications encourages mobile network operators (MNOs) to deploy new radio access technologies (RATs). The third generation partner project (3GPP) has specified an all-IP-based mobile core network: evolved packet core (EPC) which can can accommodate a 3.9-G RAT (Long Term Evolution [LTE]) as well as conventional RATs, such as UMTS and...
Available doorbell interphone systems are designed under the assumption that residents would be at home to enable the communication between them and their visitors. However, people spend a large fraction of their time away from home, thus undermining the basic assumptions of existing doorbell solutions. Recent developments in 3GPP Home Node B (HNB or Femtocell) and home gateway technologies, along...
Mobile telecommunication is evolving rapidly. People no longer only communicate with each other regardless of time and place, but also share other information that is important for tasks with which they are involved. In response to this growing trend the MediaSense framework addresses the intelligent delivery of any information to any host, anywhere, based on context-aware information regarding personal...
We describe a framework for wireless sensor network (WSN) based mobile mashup applications. The framework consists of four functional components: WSN, mobile gateway, context management platform, and mashup server. The WSN deployed in the application domain senses the physical phenomena and the human-environment interaction and expresses them in sensor readings. The mobile phone is used as the gateway...
This article addresses the media-handling aspects of multimedia conferencing in multihop cellular networks. Participation in multimedia conferences in MCNs may be confined to either the conventional cellular network or the MANET. Participation also can span both networks. However, neither the media-handling architectures currently in use in conventional cellular networks, nor the ones in use in MANETs...
