Abstract

The present invention relates to a method for resolving, for device management, a uniform resource identifier (URI) indicating a particular node and an apparatus therefor, the method comprising the steps of: finding one or more MO instances in accordance with a management object identifier (MOID) and MO instance information comprised in the URI; and finding the particular node within the one or more MO instances by means of a path, comprised in the URI, from the MO instance root node to the particular node, wherein if the MO instance information comprises a management object instance identifier (MIID), then the step for finding one or more MO instances comprises finding a unique MO instance having the MOID and MIID, and, if an MO instance having the MOID and MIID does not exist or exists in multiples, then returning an error.

First claim

The invention claimed is:

1. A method of resolving a uniform resource identifier (URI) indicating a specific node for device management in a device, the method comprising:
finding at least one management object (MO) instance according to a management object identifier (MOID) and MO instance information included in the URI;
finding the specific node using a path from an MO instance root node included in the URI to the specific node within the at least one MO instance; and
performing the device management for the specific node,
wherein, if the MO instance information includes a management object instance identifier (MIID), the MIID is unique between MO instances having a same MOID in the device, and finding the at least one MO instance includes finding a unique MO instance having the MOID and the MIID, and returning errors if no MO instance having the MOID and the MIID is present or if a plurality of MO instances each having the MOID and the MIID are present,
wherein, if the MO instance information includes a node name consisting of a first delimiting character, an alphabet letter and a second delimiting character, the alphabet letter is uniquely assigned between node names comprising the first delimiting character and the second delimiting character in one URI, and the URI further includes at least one node value field, each of the at least one node value field includes a path from a location expressed by the MO instance information to a leaf node and a node value of the leaf node, and finding the at least one MO instance includes finding a unique MO instance for enabling the leaf node to have the node value with respect to each of the at least node value field, and
wherein each of the at least one node value field includes the node name consisting of the first delimiting character, the alphabet letter and the second delimiting character.

2. The method according to claim 1 , wherein, if the MO instance information consists of an empty string, finding the at least one MO instance includes finding a unique MO instance having the MOID in the device.

3. The method according to claim 1 , wherein, if the MO instance information consists of a wildcard character, finding the at least one MO instance includes finding all MO instances each having the MOID in the device.

4. The method according to claim 1 , wherein, if the path from the MO instance root node to the specific node includes a node name consisting of a first delimiting character, an alphabet letter and a second delimiting character, the URI further includes at least one node value field, each of the at least one node value field includes a path from a location indicated by the node name to a leaf node and a node value of the leaf node, and finding the specific node includes finding a unique node for enabling the leaf node to have the node value with respect to each of the at least one node value field.

5. The method according to claim 4 , wherein each of the at least one node value field includes the node name consisting of the first delimiting character, the alphabet letter and the second delimiting character.

6. The method according to claim 1 , wherein, if the path from the MO instance root node to the specific node includes a node name consisting of a wildcard character, finding the specific node includes finding all nodes corresponding to a location of the wildcard character.

7. The method according to claim 1 , wherein, if the path from the MO instance root node to the specific node consists of one delimiting character, finding the specific node includes finding the MO instance root node.

8. A device for resolving a uniform resource identifier (URI) indicating a specific node for device management, the device comprising:
a memory; and
a processor connected to the memory,
wherein the processor finds at least one management object (MO) instance according to a management object identifier (MOID) and MO instance information included in the URI, finds the specific node using a path from an MO instance root node included in the URI to the specific node within the at least one MO instance, and performs the device management for the specific node,
wherein, if the MO instance information includes a management object instance identifier (MIID), the MIID is unique between MO instances having a same MOID in the device, and finding the at least one MO instance includes finding a unique MO instance having the MOID and the MIID and returning errors if no MO instance having the MOID and the MIID is present or if a plurality of MO instances each having the MOID and the MIID are present,
wherein, if the MO instance information includes a node name consisting of a first delimiting character, an alphabet letter and a second delimiting character, the alphabet letter is uniquely assigned between node names comprising the first delimiting character and the second delimiting character in one URI, and the URI further includes at least one node value field, each of the at least one node value field includes a path from a location expressed by the MO instance information to a leaf node and a node value of the leaf node, and finding the at least one MO instance includes finding a unique MO instance for enabling the leaf node to have the node value with respect to each of the at least node value field, and
wherein each of the at least one node value field includes the node name consisting of the first delimiting character, the alphabet letter and the second delimiting character.

9. The device according to claim 8 , wherein, if the path from the MO instance root node to the specific node includes a node name consisting of a first delimiting character, an alphabet letter and a second delimiting character, the URI further includes at least one node value field, each of the at least one node value field includes a path from a location indicated by the node name to a leaf node and a node value of the leaf node, and finding the specific node includes finding a unique node for enabling the leaf node to have the node value with respect to each of the at least one node value field.

10. The device according to claim 9 , wherein each of the at least one node value field includes the node name consisting of the first delimiting character, the alphabet letter and the second delimiting character.

11. The device according to claim 8 , wherein, if the path from the MO instance root node to the specific node consists of one delimiting character, finding the specific node includes finding the MO instance root node.

12. The device according to claim 8 , wherein, if the MO instance information consists of an empty string, finding the at least one MO instance includes finding a unique MO instance having the MOID in the device.

13. The device according to claim 8 , wherein, if the MO instance information consists of a wildcard character, finding the at least one MO instance includes finding all MO instances each having the MOID in the device.

14. The device according to claim 8 , wherein, if the path from the MO instance root node to the specific node includes a node name consisting of a wildcard character, finding the specific node includes finding all nodes corresponding to a location of the wildcard character.
