The invention provides a 5G hierarchical service QoS guarantee method and system based on a base station and a terminal system. The 5G hierarchical service QoS guarantee method comprises the steps that 1, the terminal system is initialized; step 2, initializing a traffic shaper; step 3, initializing a priority matcher; 4, judging whether data arrives or not, if yes, caching the data, and otherwise, returning to the step 3 to continue execution; step 5, judging whether the cached data accords with a data packet forwarding rule, if so, acquiring the data, otherwise, returning to the step 4 to continue execution; and step 6, judging whether the destination address of the obtained data is a local machine, if so, forwarding the local data, and otherwise, matching and forwarding the data to a base station. According to the invention, the service priority grading is flexibly carried out based on the specified field, and the QoS guarantee strategy can be adjusted in real time by changing the in-out queue rule of the
