AbstractThis work deals with provisioning of communication services via satellites for collectively mobile user groups in a heterogeneous network with several radio access technologies. The extended use of personalised user equipment beyond the coverage of one single terrestrial network by means of a satellite transport link, represents an increasingly important trend in mobile satellite communication. This trend is confirmed by the commercial introduction of broadband satellite communication to mobile terminals mounted on vehicles, trains, ships or aircraft. This work provides a consequent and structured approach for provisioning of services to broadband satellite terminals for mobile user groups and addresses: -- a systematic satellite communication system design process for collective mobile terminals; -- mobile satellite modelling at a wide range of frequencies, including current and potential frequencies; -- an optimised Pointing Acquisition and Tracking (PAT) system design including characterisation of moments for vehicle types of all mobile scenarios; -- a general hierarchical multi-service dimensioning methodology for collectively mobile user groups, including voice, data, and multimedia services; -- an aeronautical system dimensioning scheme with (capacity and handover) requirements analysis and evaluation of results for different satellite scenarios.

IP Mobile Multicast over Next Generation Satellite Networks. Design and Evaluation of a Seamless Mobility Framework for IP Multicast Communications over a Multi-beam Geostationary Satellite NetworkPillai, Prashant; Hu, Yim Fun; Jaff, Esua K. (University of BradfordFaculty of Engineering and Informatics, 2016)The inherent broadcast nature of satellites, their global coverage and direct access to a large number of subscribers give satellites unrivalled advantages in supporting IP multicast applications. A new generation of satellite systems that support regenerative on-board processors and multiple spot beam technology have opened new possibilities of implementing IP multicast communication over satellites. These new features enable satellites to make efficient use of their allocated bandwidth resources and provide cost effective network services but equally, create new challenges for mobile satellite terminals. IP mobility support in general and IP mobile multicast support in particular on mobile satellite terminals like the ones mounted on continental flights, maritime vessels, etc., still remain big challenges that have received very little attention from the research community. Up till now, there are no proposed mechanisms to support IP multicast for mobile receivers/sources in multi-beam satellite networks in open literature. This study explores the suitability of IP multicast mobility support schemes defined for terrestrial networks in a satellite environment and proposes novel schemes based on the concepts of Home and Remote subscription-based approaches, multiple interface and PMIPv6 protocol. Detailed analysis and comparison of results obtained from the proposed schemes, Mobile IP (MIP) Home and Remote subscription-based approaches (for terrestrial networks) when implemented on a reference multi-beam satellite network are presented. From these results, the proposed schemes outperform the MIP Home and Remote subscription-based approaches in terms of gateway handover latency, number of multicast packets lost and signalling cost over the satellite air interface.
PMIPv6-based IP mobility management over regenerative satellite mesh networksJaff, Esua K.; Pillai, Prashant; Hu, Yim Fun (2014)New generation of satellite systems with on-board processing (switching/routing) and support for multiple spot beams will play a key role in the provision of mobile and ubiquitous Internet-based communications. To achieve this `anywhere anytime' communication in a global multi-beam satellite network with many gateways (GWs), the challenges of beam, gateway and satellite handovers faced by the satellite terminals mounted on mobile platforms such as long haul flights, global maritime vessels and continental trains must be adequately dealt with. Network-based localised mobility protocol proxy mobile IPv6 (PMIPv6) where the IP mobility procedures are relocated from the mobile nodes to the network components has been defined by the IETF for terrestrial networks. This paper proposes how the concept of PMIPv6 could be used to support IP mobility in a mesh regenerative multi-beam satellite network. What makes this proposed approach different from that defined by the IETF is the absence of tunnelling throughout the system and the difference in the roles played by the mobility agents.
