For the past decades, networks have evolved to increase their performances,\ntheir capacities, to reduce latencies and optimize their resource management in\norder to remain competitive and adapted to the market. Today, the way consumers\nuse networks has changed and more heterogeneous services with their own\nrequirements have emerged. This has led network operators to define the network\nslicing paradigm. Network slicing creates multiple partitions in the network,\neach partition can be dedicated to a particular service allowing vertical\nmarkets and multiple services with different requirements to run on top of a\nsingle infrastructure. To allow the flexibility level required by network\nslicing, satellite technologies have to evolve. Satcoms actors have therefore\nbeen working on improving satellite equipments. Testbeds followed the\ntheoretical analysis and ESA's current project SATis5 is making it its core\ntopic. The work presented in the full-paper of this extend abstract is the next\nstep we propose to those initiatives. It focuses on the network slicing concept\napplied to satellite networks which, we believe, is a mandatory requirement for\na full integrated satellite into 5G networks. We first start by describing the\nmain challenges associated to the satellite slice definition. We then highlight\na set of requirements for such a satellite slice. Based on those requirements,\nwe construct and propose a complete Satellite Slice as a Service (S3) framework\nwhich mutualizes the satellite infrastructure to provide a seamless integration\ninto 5G networks.\n
