Abstract

Various technologies and techniques are disclosed for extending the functionality of the Open Mobile Alliance (OMA) Device Management (DM) protocol. An addition is made to the OMA DM protocol that enables the server to specify node filtering criteria as part of a query to a target node on a mobile device to indicate a sub-set of the device management data for the target node that should be returned. As another variation, a modification is made to the OMA DM protocol that enables the server to specify what attributes should be selected on the mobile device in one parameter of a target URI of the Get command, and what format the device management data should be returned in as another parameter of the target URI of the Get command.

Claims

1. A computer-readable medium having computer-executable components comprising:

an Open Mobile Alliance (OMA) Device Management (DM) structure that includes standard OMA DM management objects associated with an OMA DM protocol for managing device management data on a mobile device, the OMA DM protocol enabling a server to submit a query to a target node on the mobile device to retrieve device management data associated with the target node; and

an addition to the OMA DM protocol that enables the server to specify a node filtering criteria as part of the query to indicate a sub-set of the device management data for the target node that should be returned.

2. The computer-readable medium of claim 1, wherein the node filtering criteria is included in the query as part of an OMA DM Get command.

3. The computer-readable medium of claim 2, wherein the Get command is specified in an XML syntax.

4. The computer-readable medium of claim 3, wherein the node filtering criteria is specified in a LocURI field in the XML syntax.

5. The computer-readable medium of claim 1, wherein at least part of the node filtering criteria is specified in a new parameter added to a target URI within the query.

6. The computer-readable medium of claim 5, wherein the new parameter specifies a language syntax being used for the node filtering criteria.

7. The computer-readable medium of claim 6, wherein the language syntax is selected from the group consisting of SQL and XPath.

8. The computer-readable medium of claim 1, wherein a data section of the query contains an actual query statement that indicates the criteria that should be used to select the sub-set of device management data.

9. The computer-readable medium of claim 8, wherein the data section of the query is written in a language syntax specified in a new parameter within a target URI of the query.

10. The computer-readable medium of claim 9, wherein the target URI of the query also contains one parameter that indicates what attributes should be selected on the mobile device and another parameter that indicates what format the device management data should be returned in.

11. A method for retrieving sub-sets of data for a target node using the OMA DM protocol comprising the steps of:

sending a request to a mobile device to retrieve device management data using an Open Mobile Alliance (OMA) Device Management (DM) protocol, the request including a Get command with node filtering criteria, the node filtering criteria indicating a sub-set of device management data that should be returned for a target node; and

when the request is successfully processed on the mobile device, receiving a response from the mobile device that includes only the sub-set of device management data that meets the node filtering criteria.

12. The method of claim 11, further comprising the steps of:

when the request was attempted on the mobile device but was not successfully processed on the mobile device, receiving an error message from the mobile device that describes an error that occurred on the mobile device.

13. The method of claim 11, further comprising the steps of:

prior to the sending the request step, receiving a communication request from the mobile device that prompts the request for the device management data to be sent to the mobile device.

14. The method of claim 11, wherein at least a portion of the node filtering criteria is contained as a parameter within a target URI that is part of the Get command.

15. The method of claim 14, wherein the parameter within the target URI specifies a language syntax to be used for the filtering criteria.

16. The method of claim 14, wherein an actual query specifying the node filtering criteria is included in a separate section of the Get command, the actual query being written in the language syntax specified within the parameter in the target URL.

17. The method of claim 14, wherein the separate section is a data section of the Get command.

18. The method of claim 14, wherein the target URI has one parameter that indicates what attributes should be selected on the mobile device and another parameter that indicates what format the device management data should be returned in.

19. A computer-readable medium having computer-executable components comprising:

an Open Mobile Alliance (OMA) Device Management (DM) structure that includes standard OMA DM management objects associated with an OMA DM protocol for managing device management data on a mobile device, the OMA DM protocol enabling a server to submit a Get command to a target node on the mobile device to retrieve device management data associated with the target node; and

a modification to the OMA DM protocol that enables the server to specify what attributes should be selected on the mobile device in one parameter of a target URI of the Get command, and what format the device management data should be returned in as another parameter of the target URI of the Get command.

20. The computer-readable medium of claim 19, further having computer-executable components comprising:

an addition to the OMA DM protocol that enables the server to specify a node filtering criteria as part of the Get command to indicate a sub-set of the device management data for the target node that should be returned.
