This application discloses a deterministic transmission method, a communication apparatus, and a storage medium, and relates to the communication field. In the method, a radio access network device may generate deterministic transmission capability information of a first switching node, and send the deterministic transmission capability information to a first network element. The first switching node includes the radio access network device and a terminal. Then, the radio access network device may receive a first scheduling policy that is delivered by the first network element based on the deterministic transmission capability information of the first switching node, so that deterministic transmission can be performed according to the first scheduling policy. This reduces a delay variation of a QoS flow carrying a TSN flow in a 5GS, and can avoid a need to select a QoS flow whose delay indicator is excessively high for the TSN flow.
