Provision of Quality-of-Service in IP-based Mobile Access Networks

Research output: ThesisDoctoral ThesisMonograph

Abstract

The telecom world is converging towards IP-based networks. The Internet is be-coming increasingly popular and people expect to get wireless broadband Internet connectivity from their mobile terminals, laptop computers, Personal Digital As-sistants, and mobile phones. New services and applications are introduced con-stantly, for example, multimedia applications and electronic commerce. These new applications often require a service that is better than the default best-effort service offered by IP-based networks. The packet handling must be predictable and prompt, which implies a requirement for Quality of Service (QoS). Moreover, the movement of the mobile terminal must not disrupt the allocation of QoS.
Currently, there are a huge number of different QoS and mobility mechanisms for IP networks. Most of the QoS technologies are designed for fixed networks and work inefficiently in mobile environments. The various mobility management mechanisms have been designed to solely handle the mobility of nodes. They of-ten have serious problems when QoS signaling is needed. Moreover, the security mechanisms currently available are not optimized for mobile environments, where mobile nodes may frequently change their point of attachment to the network.
This thesis studies the most promising technologies and integrates them into a coherent fully IP-based mobile network architecture. The network is based on open protocols defined by the Internet Engineering Task Force, and on protocols studied within research projects. Mechanisms to support mobility and QoS have been studied and enhanced to support smooth handovers. Moreover, this thesis presents an enhancement that enables the use of RSVP for network internal sig-naling in case end-to-end QoS is not available.
