1. A message transmission method, comprising:
obtaining, by a core network device, a first correspondence, wherein the first correspondence comprises a correspondence between target device information and first time sensitive networking (TSN) domain information, the target device information is used to identify a target device, and the first TSN domain information is used to identify a TSN domain to which a first TSN device belongs;
receiving, by the core network device, a multicast message from a second TSN device, wherein the multicast message comprises second TSN domain information, and the second TSN domain information is used to identify a TSN domain to which the second TSN device belongs; and
sending, by the core network device, the multicast message to the target device in response to determining, based on the second TSN domain information and the first correspondence, that the second TSN device and the first TSN device belong to a same TSN domain.
