Function safety communication method and device based on data distribution service

The embodiment of the invention provides a function safety communication method and device based on data distribution service. The method comprises the following steps: a terminal receives configuration information from a service server or a core network; the configuration information is used for indicating a transmission strategy of the function security data; and the terminal transmits the function security data in the 5G private network based on the data distribution service mode according to the configuration information. According to the method disclosed by the embodiment of the invention, the data distribution service is applied to bearing the security communication layer service by utilizing the natural technical advantages of the data distribution service when bearing the key service data between discrete systems, so that the overall functional security design requirements distributed in a robot cluster system in a 5G intelligent factory can be more flexibly and effectively adapted; therefore, functio
