  • Publication number: 20200153706
    Abstract: A method and a device for terminal device management based on right control are provided. The method includes the following steps. A Get command on an access control list (ACL) of a managed node in a device management tree (DMT) from a device management (DM) server is received, where the Get command includes a Unified Resource Identity (URI) of the managed node. It is determined whether the DM server has a direct right of executing the Get command on the managed node. The Get command is processed when it is determined that the DM server has the direct right of executing the Get command on the managed node. The method and the device simplify the complexity of right management, and reduce the number of times of message interaction between the DM server and a terminal device, thereby improving the efficiency and performance of terminal device management.
