Abstract: This application discloses a communication method. When determining that a network used to provide a service does not meet a transmission requirement of service data, a terminal device requests, from a PCF, an SMF, or an NWADF, to analyze a reason why the network does not meet the transmission requirement of the service data. The PCF, the SMF, or the NWADF obtains information used to recover a service, and sends the information to a device that performs a service recovery operation, for example, the terminal device or an access network device. The information used to recover the service is used to enable the network to meet the transmission requirement of the service data.
