This application provides a communication method and apparatus. In the method, a policy control function (PCF) receives request information from a terminal or a service server. The request information requests to establish a first quality of service (QoS) flow for the terminal, and includes first indication information indicating to perform network coding on the first QoS flow. The PCF sends network coding information to an access network device accessed by the terminal and/or the terminal based on the request information. The network coding information includes second indication information indicating a QoS flow on which network coding is to be performed.

Communication method and apparatus

Address information obtaining methods and apparatuses are described. It is determined that a network element that supports a type of a first NF and that is in a first network slice needs to be accessed. The type of the first NF and information about the first network slice is sent to a network repository network element to obtain address information of the network element that supports the type of the first NF and is in the first network slice. Address information of a first network element is received from the network repository network element. The first network element is the network element that supports the type of the first NF and that is in the first network slice.
