Design And Implementation Of 5G IoT Information Collection And Slicing For Space-based Access Network

The integration of space-based networks and ground communication networks with 5G mobile communication systems as the core is the development trend of future space-ground integrated networks.The space-based network has a series of advantages such as wide coverage,little weather,and strong disaster tolerance.At the same time,it can serve as an access network to provide higher bandwidth and meet diverse business needs.In this thesis,a space-based network is used as the access network,and the ground network is sliced to achieve a specific IoT information collection scenario.A network slicing system for space-based access network with IoT information collection as the application scenario is designed.By accessing the space-based network,the network slice is selected to realize the process of IoT information collection,and according to the specific IoT information collection scenarios to achieve the design and management of slices.Firstly,this thesis investigates the research background and related technologies,performs functional requirements analysis and non-functional requirements analysis according to the working scenario,and then establishes the overall architecture of the system,conducts outline design according to the architecture sub-modules,and defines the system interaction process and data structure.Then design and implement the system in detail,design the corresponding class diagram for each outline module,draw a specific flowchart for the interaction design and implement the management interface of the system.After realizing the system function,design test cases to verify the system function.Finally,the thesis's work is summarized and the next step is prospected.
