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.
