Abstract [en]

3GPP introduced Early Data Transmit (EDT) protocol in release-15 to address Internet of things (IoT) services signaling cost and connection delay due to RRC connectivity procedure. EDT enables data transmission in MSG3 wherein traditional RACH procedure, a collision is realized at MSG3 reception. Traditional preventive approach (access class barring) may control the device access rate, but that does not always adequate to solve hidden collision due to the receiver’s limitation and devices power control mechanism. The present work aims at solving the problem by allocating extra resources pool for potential collided devices. The allocated resource of the pool is optimized based on an artificial neural network (ANN) based learning algorithm. The performance evaluation result shows that the learning-based resource allocation radically increases the data transmission success rate with EDT.

Abstract [en]

— Pilot rollouts of Cellular-IoT (C-IoT) networks just started to take place this year. In the coming years, commercial deployment will take place. However, among the plethora of low power wide area network (LPWAN) technologies, the cost-effectiveness of C-IoT is not certain for IoT service providers, small and greenfield operators.  Today, there is no known public framework for the feasibility analysis of IoT communication technologies.

Hence, this paper first presents a generic framework to assess the viability of cellular and non-cellular LPWAN technologies. Then, we applied the framework in eight deployment scenarios to analyze the prospect of LPWAN technologies like Sigfox, LoRaWAN, NB-IoT, LTE-M, and EC-GSM. We consider the inter-technology interference impact on LoRaWAN and Sigfox scalability. Our results validate that large rollout with a single technology is not cost-efficient. Also, our analysis suggests the viability of an IoT communication Technology may not be linear to cost efficiency.

Abstract [en]

This techno-economic study introduces a framework to study the deployment cost of IoT radio access network and to compare the cost and capacity of LPWAN, LPLAN, and Cellular-IoT systems. There are a plethora of Communication technologies available today. Small rollout and pilot projects are visible for most of the IoT connectivity technologies. However, The economic viability of cellular and non-cellular IoT connectivity technologies are not definite. The primary objective of this work is to analyze the cost structure of SigFox, LoRaWAN, NB-IoT, and WiFi-HaLow. In this paper, we study an urban scenario with the consideration of an Greenfield and Brownfield actor to understand the technology selection strategy of communication service prodvider's perspective. One of our findings indicates that the maintenance cost is the key cost driver for IoT radio access networks. We also point out certain bounds where a technology is potentially cost-effective.

Abstract [en]

Started as SMS ticketing, today, mobile ticketing services become a platform for combined mobility solutions that integrate mobile ticketing, bike renting, car sharing, and parking payment services. Mobile ticketing services provide a number of benefits for public transport companies and passengers, however, in some Northern European countries, the share of mobile ticket sales does not exceed 10 percent. In this paper, we analyse business models of three types of mobile ticketing services (SMS, in-app, and “Be-In Be-Out” (BIBO)) in order to identify factors that negatively affect wider penetration of mobile ticketing. In order to do so, we use STOF (Service, Technology, Organisation, and Finance) model. The research reveals that there are a number of challenges related to service, technology, and finance domains of mobile ticketing. Due to this, with the help of price policy, many public transport companies push choices of their customers towards use of plastic travel card.

Abstract [en]

Within the field of mobile payments, the market segment for mobile ticketing services is expected to grow, driven by the public transport sector. Although a large number of studies have explored the value of mobile payments to customers (ie service end users), there is a lack of research exploring the value of mobile payment and mobile ticketing for business customers (ie transport companies and retailers). This paper aims to address this gap and to explore the kinds of value that mobile ticketing services create for public transport companies. The research considers mobile ticketing services in six Northern European countries. The research findings suggest that within the business-to-business context, mobile ticketing services create multiple dimensions of value, namely enhanced technical functionality; financial value; better working environment; operational value; and reputational and customer relationship value. For passengers, meanwhile, value takes the form of convenience and service enhancement. These benefits are factors driving adoption of mobile ticketing and mobile payment services by public transport companies.

Abstract [en]

In this paper we look into the business and service platform settings for a number of sharing services interpreted in a broad sense. It includes offering and renting of unused resources, bike and car pools, car rental, co-working spaces, second hand, and recycling. The objective of the study is to identify and describe requirements and features for an open two sided service platform for sharing services. The data set includes more than 30 sharing economy services and initiatives in Sweden. Primary data is collected from around 20 persons representing cities, local communities, providers of sharing services, technology providers and start-ups. We have also interviewed a few users of sharing services, car pools, bike pools, and coworking spaces in order to get some insight about user experience.. The sharing service should typically consider temporary use of idle capacity, usage of a platform enabling sharing and transaction between any persons in an open setting. We consider sharing of both goods and services. The main findings and research contributions are: i) a more clear definition of sharing services using the model with closed/open sets of both users and resources (providers), ii) identification of key values of a sharing service platform (as compared to values of a product or a rental service), and iii) a list of key features to implement in sharing service platforms.

Abstract [en]

Intelligent Transportation Systems (ITS) are a product of convergence of Information and Communication Technology (ICT) and transport industries, with an aim to improve safety, mobility and efficiency of transportation. Ubiquitous, fast and inexpensive wireless communication and increasing vehicle computation, storage and sensing capabilities, are technological enablers for ITS. Notwithstanding technological maturity, the real challenge rises from the change the ITS market brings to the business of ICT players, as development of ITS services requires cooperation of multiple actors across industries. For ICT players, this signifies a departure from rigid telecom-era business models to a more networked structure of collaboration with other players. In this paper, we identify key business challenges that ICT players face in ITS market, by analysis of two ITS use cases.

Abstract [en]

The Random Access (RA) procedure in existing cellular networks is not capable of functioning properly during high access load conditions. For this purpose, overload control mechanisms are needed. Most proposed mechanisms in the literature offer a tradeoff between access rate and experienced delays. However, when the maximal tolerated delay and the energy spent on retransmissions are tightly bounded, the very high access rate, targeted for 5G systems, cannot be achieved. For these situations, we propose the Delay Estimation based RA (DERA)-scheme that has the potential to meet very stringent reliability requirements, even in high access load conditions. The present work shows that this goal can be achieved only at the cost of limited additional complexity. Furthermore, we also study the optimal switchover point at which the proposed scheme moves from low-load to the high-load phase. The derived tool can also be used along with other proposed RA overload control schemes, e.g.when to invoke access class barring. The performance evaluation results show that the novel DERA scheme can significantly improve the control channels’ resource utilization along with the success rate in dense deployment scenarios.

Abstract [en]

Internet of Things (IoT) is anticipated as a 'game changer' for communication service providers. Numerous IoT devices will deploy in areas where humans already inhabit. It is increasing the importance of indoor area coverage to support IoT services. This again brings the historically important questions, 'what roles an actor play and who will control the indoor coverage?' In this paper, we discuss the business actors' roles in IoT indoor service context. We identify the possible roles and activities needed to provide end-to-end indoor IoT services. Additionally, we analyze the actors' roles in IoT ecosystem. We compare the actors' roles in the context of the suitable technology and deployment choices. Our identification of roles and initial analysis shows the impact of technology and rollout choices over network business strategy. With our presented analysis, we evaluate the possible paths for mobile network operators (MNOs) on low-power wide area (LPWAN) or low-power wireless local area (LPWLAN) network deployment.
