This application provides a communication method and a communication apparatus. A first network element may obtain first REDCAP information from a terminal apparatus and subscribed second REDCAP information of the terminal apparatus. The first network element determines, based on the first REDCAP information and the second REDCAP information, whether to allow the terminal apparatus to use a service corresponding to the first REDCAP information. The first network element is an access network device or a core network device. Based on this solution, the first network element can verify, by using subscribed REDCAP information of the terminal apparatus, whether the service corresponding to the first REDCAP information can be used, to help ensure that the terminal apparatus uses only a service corresponding to the terminal apparatus, for example, help ensure that the terminal apparatus can use only a service of a first service type by using a REDCAP access technology, and cannot use a service of a second service type by using the REDCAP access technology.
