In this paper we address the emerging application of mobility to DVB-RCS/S2 systems, alternatively referred to as Satellite-On-The-Move (SOTM) communications. Broadband mobile communications represent an additional market for the satellites, of interest primarily to transport operators (of planes, ships, trains) but also to end-users in cars. To ensure economy of scale and fast development and deployment of mobile equipments, the adaptation of current satellite broadcast and interactive broadband standards is foreseen. This paper presents issues and techniques dealing with network and mobility management for DVB-RCS/S2 systems. It is shown that synchronization can be ensured by using proper methods even when spectrum spreading techniques are used and that seamless beam handovers can be achieved.
