ABSTRACT:
A method of disseminating topology information related to a subscriber in a system having one or more networks, each network having access devices and policy functions, includes identifying a current location of the subscriber by a serving policy function. The method further includes forwarding information relating to the current location from the serving policy function to an anchor policy function associated with the subscriber. The process of identifying the location of the subscriber and forwarding the information to the anchor policy server is repeated each time the subscriber changes its physical location. The system uses the current location information to route policy information from the anchor policy function to the policy function that is serving the subscriber. The system may use a push model, a pull model, or a combination thereof, to disseminate the topology information.
