ABSTRACT Beyond 3G (B3G) environments typically consist of multi-homed terminals and wireless overlay networks. This paper presents a categorization of IP-level mobility management solutions for B3G environments. Closely observing the mobility requirements of a wide range of possible applications, the paper also motivates the consideration of a new mobility management approach in B3G environments, whereby location management (i.e., reaching mobile end-users at the IP-level for session invitations) is decoupled from handover management (i.e., switching ongoing sessions, collectively or individually, to another access network whenever appropriate). For example, one can use cellular GPRS/UMTS networks for location management and Wi- Fi or cellular networks for handover management. The paper elaborates upon the merits of such so-called context-aware mobility solutions, which are attained from an optimum use of the mobility management features embedded in the underlying infrastructure.

    ABSTRACT: Converged networks are viewed as a multi-access platform on which fixed and mobile communications can be easily merged into a unified system thus enabling the deployment of rich and personalized services. In this paper, we provide the outcomes of our research into the challenges introduced by terminal mobility in converged networks. This was achieved by carrying out performance based evaluations on various mobile network properties at the access, core and application levels of converged networks and then analysing how they affect the platform individually and as a whole. We also provide the details of our state-of-the-art experimental tests, and analyses that were carried out on emulated converged network test beds, novel architectures, recommendations and extensions which were specifically developed to improve the performance of mobile applications and services in converged networks building on key technologies such as Mobile IPv6, Session Initiation Protocol (SIP) and Peer-to-Peer (P2P) Networks.

    ABSTRACT: A 4G-environment is based on the integration of 3G mobile and other wired and wireless technologies into an all-IP network environment. Central to such an environment is a 4G-service platform, which offers services such as AAA, mobility management and session control, and also mediates between the users and providers of these services. Each service platform and its associated users, service providers and access networks constitute a service platform domain. Extension of offered functionality and expansion of coverage is obtained by federation between multiple service platform domains. In the 4GPLUS project a conceptual framework is developed for 4G-environments, which specifies the functionality and structure of the 4G-service platform and the concept of federation. Several key aspects of this framework have been refined, implemented and prototyped within this project. This paper provides an overview of the 4G-concepts developed within the project and the main results achieved.

    ABSTRACT: Simultaneous operation of multiple network interfaces can benefit mobile devices with diverse network interfaces. This paper outlines an IP-level network activation strategy that aims at optimum use of the complementary features of the underlying networks. A key design issue in such strategies is the energy cost of different network interfaces. As a step towards validating and fine-tuning our strategy, we devised an experimental setting to measure the relative energy consumption of WiFi and GPRS interfaces in two modern mobile devices. The paper reports the experimental method and results. Our study indicates that the proposed strategy –in this case, reaching devices from the GPRS interface and, whenever appropriate, handing over some sessions to the WiFi interface– is plausible from energy consumption viewpoint and in some cases it outperforms the existing methods. The energy consumption model obtained will be used to make the network activation strategy energy aware.
