“…With the location and multimedia capability of fixed multimedia devices available, the actual location of the mobile device would be sufficient to find candidate multimedia devices in the neighborhood. Context information is more general than presence and location information; Brok, Vemuri, Meeuwissen, and Batteram [6] describe a framework to utilize context information from various sources in an IMS application server.…”

“…For this reasoning logic, which is not the focus of this paper, geographical location and presence information (context information) of the mobile node and candidate local nodes are expected to be necessary. Figure 4 shows how the SSC and context-reasoning node could be integrated in IMS, re-using a model described in [6]. Basically, the context reasoning node in the SSC can use a subscribe mechanism to be notified about the location changes of the client device (from its presence user agent, or a network-side user-location mechanism through a presence external agent) and match it with the known capabilities and location of the fixed devices, and optionally, also other mobile …”

“…So, the actual distribution of a stream can be based on the network location(s) and number of receivers, the efficiency/cost of multicast/broadcast versus unicast per network segment, and context information from the network (e.g., predicted/inferred content popularity or network usage) [8]. The concept also allows reduced signaling to the content provider: i.e., the MBC-AS could handle INVITEs that would utilize an existing relay on behalf of a content provider.…”

Services like telecommunication, messaging, radio/television broadcast, and Web browsing are increasingly using the same Internet Protocol (IP)-based transport technology. Converged IP next-generation networks (NGNs) will enable easier blending and personalization of those services. For popular content, technologies like caching, broadcasting, and multicasting aim to increase network efficiency but also introduce extra complexity and bandwidth overhead. Additionally, the sheer amount of available content and the increasing flexibility for the end user to request content at any time from any place make it increasingly difficult to determine content popularity in order to predict the efficiency of using content distribution techniques. This paper describes a model for wireless networks to use network characteristics and a prediction of the popularity distribution to calculate the optimal combination of unicast and broadcast techniques when offering a number of media channels to the end user. Furthermore, an approach is described to optimize personalized content distribution efficiency in converged IP NGN networks utilizing efficiency calculations with this model. © 2008 Alcatel-Lucent.commonly distributed content, i.e., television (TV) channels, with additional content aimed specifically at a particular user or user group. Such content may include overlay elements such as text, graphics, pictures, animations, or video clips, and additional or enhanced audio-and/or video-specific segments.Content distribution techniques mainly improve efficiency for "popular" content. However, personalization and an almost infinite choice of content make it difficult to determine content popularity at a specific moment in time. This paper describes a content distribution efficiency model for wireless networks and proposes a dynamic mechanism to provide efficient

“…In simple IM tools, the status feature determines the availability of others by technical means, e.g. the system deduces from the user being logged into the system a "present" status; a lack of user activity is usually interpreted as "away" [Grinter and Palen 2002] (for presence signaling protocols and architectures see [Brok et al 2006]). In RTC systems, presence information can originate from all devices a user possesses [Jennings 2006].…”

This paper presents Real-Time Collaboration (RTC), a new and emerging type of Information and Communication Technology (ICT) system that has its roots in both the telecommunications and groupware market. The aim of the paper is twofold. First, it outlines the evolution of RTC systems and offers a conceptualization of RTC consisting of usage scenarios and four main building blocks-integration of communication channels, presence information, context integration, and further collaboration features. Second, in order to understand the organizational implications of this complex and socially embedded information system, the paper intends to offer a starting point for future research on RTC by touching upon and systematizing different directions and typical questions for researching RTC and its organizational implications.
