Communication method and related device
The present disclosure discloses example communication apparatuses. One example communication apparatus includes sending request information from a first network device to a second network device, where the request information includes an identifier of a network slice, configuration information of a data radio bearer corresponding to the identifier of the network slice, and first general packet radio service tunneling protocol-user plane (GTP-U) tunnel address information corresponding to the identifier of the network slice.
