  • Publication number: 20230275815
    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.

  • Publication number: 20230045030
    Abstract: A user service processing method in a charging system is as follows: A charging trigger device provides initial quota application mode indication information for a charging processing device, so as to indicate an initial quota request mode previously applied by the charging trigger device for a user service. The charging processing device performs charging processing on the user service based on the indication information, and delivers a charging processing result to the charging trigger device, to enable the charging trigger device to change a charging operation on the user service. In this way, by changing a cooperation relationship between the charging processing device and the charging trigger device, a balance between performance of the charging system and a credit control risk, or between an access delay and a credit control risk is implemented.
