ABSTRACT:
A system, apparatus, and method for routing communication requests based on user presence information. A network entity subscribes to the presence information of a user, and receives notifications of the users' presence information when the user has registered with the network or the presence information has changed. In response, the network entity creates routing instructions based on the presence information. In this manner, incoming communication requests can be appropriately routed according to the routing instructions.
