Method and system for supporting the communication of presence information among computing devices of a network
First Claim
1. A computing system with a processor and memory for assigning presence agent functionality to a client computing device, the client computing device operating a presence user agent for generating presence information pertaining to a user, comprising:
- computer readable instructions to determine if a server computing device has presence agent functionality;
computer readable instructions to send presence information pertaining to the user to the server computing device when it is determined that the server computing device does have presence agent functionality; and
computer readable instructions to register the client computing device with a registrar as a presence agent on behalf of the user when it is determined that the server computing device does not have presence agent functionality, wherein the client computing device receives subscription messages from watchers to subscribe to presence information of the user and transmits presence information to the watchers so that the client computing device functions as the presence agent for the user, rather than the server computing devicewherein the computer readable instructions are stored in the memory for execution by the processor.

Abstract
A method and system for aggregating presence information generated by multiple devices associated with a single user is presented. A server acting as a presence agent on behalf of a first user and the first user'"'"'s computing device receives and responds to a subscription request generated by a computing device operated by a second user that wishes to be permitted as a watcher of the first user. If the server is not capable of acting as a presence agent, then the first user'"'"'s computing device assumes the role of a presence agent.

7. A computer-readable storage device that is not a signal storing code that, when executed by a client computing device, causes the client computing device to assign presence agent functionality to the client computing device, the client computing device operating a presence user agent for generating presence information pertaining to a user, the computer-readable storage device storing code to:
-
determine if a server computing device has presence agent functionality; when it is determined that the server computing device does have presence agent functionality, execute software for sending presence information pertaining to the user to the server computing device; and when it is determined that the server computing device does not have presence agent functionality, register with a registrar as a presence agent on behalf of the user, wherein the client computing device receives subscription messages from watchers to subscribe to presence information of the user and transmits presence information to the watchers so that the client computing device functions as the presence agent for the user, rather than the server computing device. - View Dependent Claims (8, 9, 10, 11, 12)
