Driven by a competitive business climate, handset user interface design is receiving a great deal of study and attention. Technology advances have turned the mobile phone into the ultimate portable tool for information, communications, productivity, and entertainment. Designing a user interface (UI) that can handle these capabilities—and still remain useful, usable, and uncomplicated—is the cha...
Modern mobile communication networks provide a variety of voice and data services. The latest set of mobile technology specifications by the 3rd Generation Partnership Project (3GPP) is referred to as Long Term Evolution (LTE). In this paper, the performance of a wireless network where LTE is used at the Medium Access Control (MAC) layer is evaluated. User Datagram Protocol (UDP) traffic is con...
Content services for mobile phone subscribers compose a new business area based on the constellation of and symbiotic relationship between mobile telecommunication operators and content providers. In this paper we discuss the development and internationalization of the CPA (Content Provider Access) business model and platform by the Norwegian telecommunication operator Telenor.

For a sample of 9,799 subscribers to single mobile operator, we observe switching between handsets July, 2011, and December, 2014. We estimate discrete choice model in which account for disutility from different operating systems brands. Our estimation results indicate the presence significant inertia use our simulate market shares absence costs conclude that Android smaller would increase at e...
Since the early nineties, anonymous and asynchronous dissemination of information has been a basic building block for typical distributed application such as stock exchanges, news tickers and air-traffic control. With the advent of ubiquitous computing and of the ambient intelligence, information dissemination solutions have to face challenges such as the exchange of huge amounts of information...
Video call capabilities in 3G mobile handsets and higher data rate in HSPA networks are fuelling resurgence in video telephony. This enables the delivery of exciting video applications to subscribers. The addition of Interactive Voice and Video Response (IVVR) opens up a wide stream of interactive video applications. In this paper we present a comparative study on the encoding tools and the tec...
In cellular networks, the locations of all subscribers are continously tracked even when they only passively carry their mobile devices with them. This privacy sensitive data can be an invaluable source of information, not only for benevolent parties. We therefore present CallForge, the concept of a location management scheme that preserves the subscribers’ anonymity – in many cases even while ...
Abstract In this paper, we analyze how fixed-mobile (quadruple-play) bundling impacts the decision of consumers to churn telecommunications services. We use a database from an European operator fixed and mobile services which includes information about 9.6 million broadband subscribers 14.2 between March 2014 February 2015. These data is combined with socio-demographic characteristics each muni...
This paper describes an event dissemination algorithm that implements a topic-based publish/subscribe interaction abstraction in mobile ad-hoc networks (MANETs). Our algorithm is frugal in two senses. First, it reduces the total number of duplicates and parasite events received by the subscribers. Second, both the mobility of the publishers and the subscribers, as well as the validity periods o...
