Abstract: A method for switching of multi-carrier and device are provided. The method comprises: receiving a message sent from a source radio access network (RAN) node corresponding to a first link and comprising information of a second link; according to the information of the second link, establishing a connection between a target RAN node corresponding to the first link and an RAN node corresponding to the second link, so as to perform data transmission. The first link is a link in a first Radio Access Technology (RAT) network, and the second link is a link in a second RAT network. Embodiments of the present disclosure can ensure the continuity of the throughput of data transmission during switching under aggregation of multiple RAT carriers.

Abstract: Embodiments of the present disclosure provide a multicast service transmission method, including: a terminal receives from a first cell, configuration information corresponding to an MBMS, where the configuration information corresponding to the MBMS includes: a cell identity of at least one second cell; the terminal obtains configuration information of the second cell based on the cell identity of the second cell; and receives from the second cell, an MTCH based on the configuration information of the second cell. This resolves a problem that the terminal can receive in one cell, an MCCH and the MTCH corresponding to the MBMS, and achieves an effect that the terminal device can receive, from the first cell and the at least one second cell, a same multicast service by using a carrier aggregation technology.

Abstract: A multicast transmission method is disclosed. A base station of a first cell obtains first multicast resource information of at least one second cell, where the base station of the first cell is different from a base station of each second cell; and the base station of the first cell sends second multicast resource information to user equipment, where the second multicast resource information is used to indicate a resource configuration used by each second cell to transmit multicast service data. The base station of the first cell actively sends obtained multicast resource information to the user equipment in a broadcast manner. In this way, the base station of the first cell does not need to configure, in a unicast manner for each user equipment, a resource location for sending/reading the multicast service data of each second cell, thereby reducing signaling overheads.

Abstract: This application provides a measurement method, a terminal device, and an access network device. The measurement method includes: measuring, by a terminal device, signal quality of a plurality of beams, where the signal quality of the plurality of beams is obtained by using synchronization signal blocks; the signal quality of the plurality of beams includes signal quality of a same beam at different moments, and the plurality of beams belong to one cell; and obtaining, by the terminal device, signal quality of the cell based on the signal quality of the plurality of beams. In this way, cell measurement based on a synchronization signal is implemented, and the signal quality of the cell obtained based on the signal quality of the plurality of beams at the different moments is more accurate.
