Abstract

A system determines presence updates associated with presence user agents (PUAs), where the presence updates indicate changes in a presence status associated with each of the PUAs. The system further determines an application type associated with each of the PUAs and routes the presence updates to respective presence network agents (PNAs) based on the determined application type.
