Abstract: Example methods for processing a system message and network devices are described herein. One example method includes obtaining, by a user terminal, indication information, wherein the indication information indicates that a system message of a cell cluster has changed or whether a system message of a cell cluster has changed, wherein the cell cluster comprises a set of at least one cell. The user terminal can then determine whether currently used information about the cell cluster needs to be updated. In some instances, obtaining the indication information comprises obtaining a system information update message. In those instances, determining whether currently used information about the cell cluster needs to be updated can include updating the currently used information about the cell cluster or updating a system message of a cell in the currently used cell cluster based on the indication information in the system information update message.

Abstract: A method includes: sending, by a first network device, a first configuration message to a terminal device, where the first configuration message is used to instruct the terminal device to configure a second ciphering/deciphering function associated with a second network device and share a first data packet numbering/reordering function, and the terminal device is configured with the first data packet numbering/reordering function and a first ciphering/deciphering function associated with the first network device; and receiving, by the first network device, a first configuration complete message sent by the terminal device. In this embodiment, the first configuration message is used so that the terminal device may configure the function associated with the second network device. Therefore, during handover, the terminal device may simultaneously perform data transmission with the second network device and the first network device, to reduce or avoid a service interruption time caused by handover.

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.
