The present invention relates to a device management (Device Manage) technology, and more particularly to a method, a terminal device and a system for processing a result of a feedback device management server. Background technique

As mobile data services become more sophisticated and complex, services are increasingly dependent on terminals. As a carrier for users to use mobile services, mobile terminals have become an indispensable part of the mobile operation service system. In order to better enable the terminal to quickly improve its ability to cope with the increasingly fierce market competition, and to remotely manage the terminal equipment more conveniently, efficiently and quickly, all operators and terminal manufacturers are committed to improving the remoteness of the terminal equipment. Management ability.

In the device management process, the Device Management No Session (DM Sessionless) specification proposes a method for completing device management without a DM session. In this method, the DM server sends a Sessionless message to the terminal device by using a PUSH mechanism (push mechanism), such as a WAP Push, a SIP Push, or a broadcast. The terminal device parses the Sessionless message to implement management of the device. Therefore, in DM Sessionless, it is avoided to communicate through the data link like the DM Management Session, so that device management can be realized in a complex network environment. As shown in Figure 1, the schematic diagram of the session-free device management process proposed by the existing DM Sessionless specification, as shown in the figure, the device management server sends the sessionless management message to the device management client, and the device management client only No session management messages are verified and processed.
