Aiming to mitigate the training difficulty of deep neural models at the edge of network, this paper introduces a deep learning model training framework based on 5G edge computing. The presented training framework connects smart devices and performs data communication via the 5G edge computing access network. The model training is firstly implemented in edge computing nodes using local data, and then the model parameters are collected and globally updated in the central server. This scenario ensures the diversity of data sets for training, reduces networks pressure and protects privacy of local data. Thus, it is a promising edge computing architecture for deep learning.

5G completed the first phase of functional standardization work, and the independent and non- independent networking NR standards have been finished. In the evolving 5G process, satellite communication technology provides a powerful solution for 90%of regional and application scenarios.Achieving 5Gsatellite architecture requires further standardization to fully exploit the advantages of multiple networks, making the entire system adaptable, flexible and dynamic. China has already reached the world’s advanced level in the key technologies of ground 5G. But China has just started in the standardization of 5Gsatellite technology. Starting from the standardization process of 5Gsatellites at nation and abroad, this paper focuses on the content and direction of 5G satellite standardization. This paper proposes organizational and development suggestions that are compatible with China's development status.The research content mainly includes the development process of 5G satellite standardization at home and abroad, the current 5G satellite standardization content and development trend, domestic organization form and development suggestions.
