Abstract: Example message transmission methods and apparatus are provided. One example method includes obtaining a first correspondence by a core network device, where the first correspondence includes 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. The core network device receives a multicast message from a second TSN device, where the multicast message includes second TSN domain information which is used to identify a TSN domain to which the second TSN device belongs. The core network device sends the multicast message to the target device when 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.

Abstract: A communication method enables a base station to allocate a radio resource to a data packet of a time sensitive networking (TSN) network in a scenario in which the TSN network transmits the data packet through a 5G network. The method includes: obtaining, by an access network device, a first traffic pattern, and allocating a radio resource to a first traffic based on the first traffic pattern. The first traffic pattern includes time information of the first traffic with respect to a first clock. The first clock is a clock used by a first network. The access network device belongs to the first network. The time information includes a time point and/or a period at/in which a data packet of the first traffic arrives at the first network.

Abstract: The present disclosure relates to wireless communication methods, terminal devices, and network devices. In one example method, a network device sends timing advance timer (TAT) configuration information to a terminal device, where the TAT configuration information is used by the terminal device to configure duration of a TAT. The terminal device receives the TAT configuration information sent by the network device. The terminal device configures the TAT based on the TAT configuration information, and asynchronously sends uplink data to the network de vice based on a running status of the TAT. The network device receives the uplink data sent by the terminal device based on the TAT configuration information.

Abstract: Embodiments of this application provide a data transmission method and apparatus. The method includes: receiving data sent by a terminal in an inactive state, where the data includes to-be-sent data sent by the terminal and identification information of the terminal; determining an anchor base station of the terminal based on the identification information; and sending the data to the anchor base station, so that the anchor base station sends the data to a core-network device. The uplink data of the terminal is forwarded to the anchor base station by using a serving base station and through an interaction between the anchor base station and the serving base station that currently provides an air interface resource for the terminal, and is then transmitted to a core network.
