Method for communicating device management data changes

1. A method performed by a mobile device, comprising:

receiving a command from a first device management (DM) server to perform an operation on a node of an Open Mobile Alliance (OMA) DM tree, the operation being one of creating, modifying, and deleting;

performing the operation on the node;

creating a first delta record based on the command received from the first DM server, the first delta record indicating the operation performed on the node and a Uniform Resource Identifier (URI) of the node, the first delta record further including a sequence number, time stamp, and authority identifier identifying the first DM server;

accumulating the first delta record with a plurality of delta records on the mobile device in a data structure that is separate from the OMA DM tree to form a plurality of accumulated delta records;

pushing delta records, which were accumulated in the data structure separate from the OMA DM tree, to a second DM server when a threshold relating to a maximum quantity of delta records for the delta records is met or exceeded, the pushing providing to the second DM server, according to an access control list, only certain delta records that the second DM server is authorized to receive; and

rolling back an event sequence, wherein the rolling-back is based on time stamps and sequence numbers associated with the plurality of accumulated delta records.

2. The method of claim 1 wherein the threshold relates to a storage space used for the delta records.

3. The method of claim 1 further comprising, after the pushing, purging delta records that were pushed.

4. The method of claim 1 wherein the second DM server is the first DM server.

5. The method of claim 1 wherein the second DM server is different from the first DM server.

6. The method of claim 1 , further comprising, prior to creating the first delta record, receiving from the DM server a command to create the first delta record.

7. A mobile device comprising:

a processor;

storage;

a communications subsystem;

wherein the processor, storage and communications subsystem cooperate to perform the operations of:

receive a command from a first device management (DM) server to perform an operation on a node of an Open Mobile Alliance (OMA) DM tree, the operation being one of creating, modifying, and deleting;

perform the operation on the node;

create a first delta record based on the command received from the first DM server, the first delta record indicating the operation performed on the node and a Uniform Resource Identifier (URI) of the node, the first delta record further including a sequence number, time stamp, and authority identifier identifying the first DM server;

accumulate the first delta record with a plurality of delta records in a data structure, the data structure being separate from the OMA DM tree to form a plurality of accumulated delta records;

push delta records which were accumulated in the data structure separate from the OMA DM tree, to a second DM server when a threshold relating to a maximum quantity of delta records for the delta records is met or exceeded, wherein the communication interface is configured to push to the second DM server only certain delta records that the second DM server is authorized to receive according to an access control list; and

roll back an event sequence, wherein the rolling-back is based on time stamps and sequence numbers associated with the plurality of accumulated delta records.

8. The mobile device of claim 7 wherein the threshold relates to a storage space used for the delta records.

9. The mobile device of claim 7 wherein the DM client is operable, after the delta records are pushed, to purge said delta records.

10. The mobile device of claim 7 wherein the second DM server is the first DM server.

11. The mobile device of claim 7 wherein the second DM server is different from the first DM server.

12. The mobile device of claim 7 , wherein the processor, storage and communications subsystem further cooperate to perform the operations of, prior to creating the first delta record, receiving from the DM server a command to create the first delta record.

13. A non-transitory computer readable medium storing instructions which, when executed, cause a mobile device to perform the operations of:

receiving a command from a first device management (DM) server to perform an operation on a node of an Open Mobile Alliance (OMA) DM tree, the operation being one of creating, modifying, and deleting;

performing the operation on the node;

creating a first delta record based on the command received from the first DM server, the first delta record indicating the operation performed on the node and a Uniform Resource Identifier (URI) of the node, the first delta record further including a sequence number, time stamp, and authority identifier identifying the first DM server;

accumulating the first delta record with a plurality of delta records on the mobile device in a data structure that is separate from the OMA DM tree to form a plurality of accumulated delta records; and

pushing delta records, which were accumulated in the data structure separate from the OMA DM tree, to a second DM server when a threshold relating to a maximum quantity of delta records for the delta records is met or exceeded, the pushing providing to the second DM server, according to an access control list, only certain delta records that the second DM server is authorized to receive; and

rolling back an event sequence, wherein the rolling-back is based on time stamps and sequence numbers associated with the plurality of accumulated delta records.

14. The non-transitory computer readable medium of claim 13 wherein the threshold relates to a storage space used for the delta records.

15. The non-transitory computer readable medium of claim 13 further comprising, after the pushing, purging delta records that were pushed.

16. The non-transitory computer readable medium of claim 13 wherein the second DM server is the first DM server.

17. The non-transitory computer readable medium of claim 13 wherein the second DM server is different from the first DM server.

18. The non-transitory computer readable medium of claim 13 wherein the instructions, when executed, further cause the mobile device to perform the operations of prior to creating the first delta record, receiving from the DM server a command to create the first delta record.
