Abstract: A Device Management (DM) method, a DM apparatus and a DM system are provided. The DM method includes: receiving a DM instruction; parsing the DM instruction to be used for managing at least two terminal devices, in which management data, used for managing the at least two terminal devices, indicated in the DM instruction is the same; obtaining the management data indicated in the DM instruction only once; and delivering the obtained management data to the at least two terminal devices so that the at least two terminal devices perform DM according to the management data. The utilization of an external interface of a gateway device may be improved by adopting the DM method, the DM apparatus and the DM system.

Abstract: The present invention relates to the field of communications technologies and discloses a method and an apparatus for performing device management through a gateway device and a Device Management Server (DMS). The method for performing device management through a gateway device includes: receiving a register message which carries a terminal ID and a gateway device address; associating and storing the terminal ID and the gateway device address; obtaining the gateway device address according to the association record; and sending a Device Management (DM) notification message to the gateway device according to the gateway device address so that the gateway device performs corresponding processing according to the DM notification message. With the technical solution of the present invention, a DMS is able to send a DM notification to a user terminal through a gateway device.
