Abstract

A method and system for processing a data request from a watcher for a target at a server, the method receiving a request for information; searching through a policy for rules to be applied based on the watcher; applying any rules found by the searching, the rule causing a transformation of the information into at least one aspect interpretable by the watcher, the applying utilizing a presence information data format transformation; and returning the at least one aspect incorporated in a presence information data format.

Claims

1. A method for processing a data request from a watcher for a target at a server comprising:

receiving, at the server, a request for presence information of the target from the watcher, via a network;

searching, based on the request from the watcher, through authorization rules for rules to be applied based on the watcher;

applying at least one rule from the searching step in response to said watcher request, the rule causing a transformation of the information into at least one presence aspect of the target interpretable by the watcher, the applying utilizing a presence information data format transformation, comprising aggregating multiple aspects, and wherein the information requested by the watcher is transformed from raw presence information prior to being transmitted; and

returning, from the server to the watcher, the at least one presence aspect of the target incorporated in a presence information data format via the network.

2. The method of claim 1, wherein the request for information is a subscription request.

3. The method of claim 1, wherein the authorization rules are predetermined based on a user setting.

4. The method of claim 1, wherein the information is location information.

5. The method of claim 1, wherein the applying comprises invoking an access layer to process the transformation.

6. The method of claim 5, wherein the returning is performed by the access layer.

8. The method of claim 1, wherein the at least one aspect is an aspect defined by the Open Mobile Alliance.

9. The method of claim 1, wherein returning comprises utilizing a presence information data format having sub-elements for the aspects.

10. The method of claim 9, wherein the sub-elements can be ignored by the watcher if not recognized by the watcher.

11. The method of claim 1, wherein the applying further utilizes a filter from the watcher.

12. A tangible, non-transitory computer readable medium storing a program code which when executed by a processor of a computing device causes said computing device to perform the method of claim 1.

7. The method of claim wherein the access layer combines aspects from multiple servers.

13. A network element configured for processing a data request from a watcher for a target, the network element comprising:

a processor; and

a communication subsystem,

the processor and the communication subsystem cooperating for;

receiving a request for presence information of the target from the watcher via a network;

searching, based on the request from the watcher, through authorization rules for rules to be applied based on the watcher;

applying at least one rule from the searching step in response to said watcher request, the rule causing a transformation of the information into at least one presence aspect of the target interpretable by the watcher, the applying utilizing a presence information data format transformation, comprising aggregating multiple aspects, and wherein the information requested by the watcher is transformed from raw presence information prior to being transmitted; and

returning the at least one presence aspect of the target incorporated in a presence information data format.

14. The network element of claim 13, wherein the network element comprises at least one of a location server and a presence server.

15. The network element of claim 13, further comprising an access layer to process the transformation.

16. The network element of claim 15, wherein the access layer is configured to aggregate aspects from a presence server and a location server.
