The present application provides a parameter configuration method, a communication device, and a storage medium. The parameter configuration method is applied to a first communication node and includes: receiving a frame format of a packet data unit (PDU) session sent by a second communication node, where the frame format of the PDU session includes at least one of the following indication information: application packet identification information, application data unit (ADU) identification information, a quality of service (QoS) sub-flow identifier, and a QoS sub-flow priority; and determining scheduling priorities or resource allocation weights of different IP packets in a same QoS flow according to the frame format of the PDU session.
