At the same time, the basic service layer can also interact with the bottom layer across layers and provide selection and switching of the bottom layer transmission path according to the service requirements and the transmission situation. The basic application layer is used to implement various application functions. The basic application layer can define a general application service framework including a general communication framework and a general audio / video framework for common business demands, for calling by specific applications to realize modular design.
