System, apparatus and method for providing partial presence notifications

Abstract

A computer-implemented apparatus and method for communicating partial notifications relating to a presentity's presence information. The communication may be effected between presence servers and terminals coupled to the presence servers via a network. At least one presentity is identified to which a terminal has requested presence services. A presence document is created, where the presence document includes presence information corresponding to the presentity. The presence information is configured as partial presence information comprising less than a total of the presence information available for the presentity. The presence document having the partial presence information is communicated to the terminal requesting the presence information.

What is claimed is: 
     
         1 . A computer-readable medium having instructions stored thereon which are executable by a computer system for communicating presence information between presence servers and terminals coupled to the presence servers via a network by performing steps comprising:
 identifying at least one presentity to which a terminal has requested presence services;   creating a presence document including presence information corresponding to the presentity;   configuring the presence information as partial presence information comprising less than a total of the presence information available for the presentity; and   communicating the presence document having the partial presence information to the terminal requesting the presence information.
