Presence and awareness communication services reverse the classical phone model where the originators of calls are blind to the receiver's availability and therefore encourage spontaneous communications. The result is that a whole new set of features and interactions exist that never existed in the old style of voice telephony.
This tutorial reviews protocols and platforms that can be used for presence and awareness. At the end of the tutorial, the participants should have a reasonable understanding of:
Although the talk will be a tutorial on Presence and Awareness protocols, it will also expose some research issues on presence and awareness policies by introducing a Presence and Availability Policy Language (PAPL) based on the IETF Call Processing Language (CPL) structure.
