Abstract: Embodiments of this application provide a communication method, apparatus, a terminal, a network device, and a storage medium. After the terminal receives, from the network device, indication information used to indicate the terminal to report traffic pattern information of a first logical channel, a first PDU session, a first application, a first radio bearer, or a first QoS flow, the terminal reports the traffic pattern information of the first logical channel, the first PDU session, the first application, the first radio bearer, or the first QoS flow based on the indication information. In this manner, the terminal reports, based on the indication, the traffic pattern information of only the logical channel, the PDU session, the service, the radio bearer, or the QoS flow that is indicated by the network device.
