Method for providing node information, method for acquiring node information, and device
View Patent ↗The present invention discloses a method for providing node information, a method for acquiring node information, a Device Management (DM) server and a terminal device. The method for providing node information includes: receiving a command including a Management Object Identifier (MOI) and node object information ( 41 ); and returning node information according to the MOI and the node object information in the command ( 42 ). The DM server includes a sending module and a receiving module. The terminal device includes a receiving module and a returning module. The DM server acquires node values of multiple nodes of multiple MO instances through one command, thereby increasing efficiency of the DM server acquiring node information, and saving OTA resources.
1. A method for providing node information, the method comprising:
receiving, by a terminal device, a Get command of Open Mobile Alliance Device Management (OMA DM) for requesting node information of a target node from a DM server, the Get command including a Management Object Identifier (MOI) and a relative uniform resource identifier (URI) of the target node which is relative to a root of a Management Object (MO) instance corresponding to the MOI;
identifying, by the terminal device, the target node according to the MOI and the relative URI of the target node; and
returning, by the terminal device, the node information of the target node requested by the Get command to the DM server,
wherein returning the node information comprises returning the node information of the target node corresponding to the relative URI in the MO instance.
2. The method for providing node information according to claim 1 , wherein the node information of the target node includes a node value of the target node.
3. The method for providing node information according to claim 1 , wherein the node information of the target node includes an absolute URI of the target node.
4. The method for providing node information according to claim 1 , wherein the MOI is appended with “?”.
5. The method for providing node information according to claim 4 , wherein the MOI appended with “?” and the relative URI are included in an Item/Data element within the Get command.
6. A method for acquiring node information, the method comprising:
sending, by a Device Management (DM) server, to a terminal device a Get command of Open Mobile Alliance (OMA) DM, the Get command including a Management Object Identifier (MOI) and a relative uniform resource identifier (URI) of a target node which is relative to a root of a Management Object (MO) instance corresponding to the MOI; and
receiving, by the DM server, node information of the target node, wherein the node information of the target node is returned according to the MOI and the relative URI of the target node,
wherein the receiving the node information comprises: receiving the node information of the target node corresponding to the relative URI in the MO instance.
7. The method according to claim 6 , wherein the relative URI comprises a specified character, and the specified character is used to represent a placeholder node or an unnamed node.
8. The method for acquiring node information according to claim 6 , wherein the node information of the target node includes a node value of the target node.
9. The method for acquiring node information according to claim 6 , wherein the node information of the target node includes an absolute URI of the target node.
10. The method for acquiring node information according to claim 6 , wherein the MOI is appended with “?”.
11. The method for acquiring node information according to claim 10 , wherein the MOI appended with “?” and the relative URI is included in an Item/Data element within the Get command.
12. A terminal device, comprising;
a receiver configured to receive a Get command of Open Mobile Alliance Device Management (OMA DM) that is sent by a device management (DM) server and includes a Management Object Identifier (MOI) and a relative uniform resource identifier of a target node which is relative to a root of a Management Object (MO) instance corresponding to the MOI; and
a transmitter configured to return node information of the target node corresponding to the relative URI in the MO instance according to the MOI and the relative URI in the Get command.
13. The terminal device according to claim 12 , wherein the node information of the target node includes a node value of the target node.
14. The terminal device according to claim 12 , wherein the node information of the target node includes an absolute URI of the target node.
15. The terminal device according to claim 12 , wherein the MOI is appended with “?”.
16. The terminal device according to claim 15 , wherein the MOI appended with “?” and the relative URI are included in an Item/Data element within the Get command.
