Abstract: An apparatus comprising a policy enforcement point (PEP) configured to enforce firewall policies in a network, and a policy decision point (PDP) coupled to the PEP and configured to manage the PEP based on at least one firewall policy option received from at least one node. Also disclosed is a network component comprising at least one processor configured to implement a method comprising receiving a request from a node regarding a firewall policy entry, authenticating the node, processing the request to manage a firewall using a firewall control protocol, and sending a reply to the node regarding processing the request. Also disclosed is a method comprising signaling a PDP to establish a session associated with a source address and a requested protocol, and receiving an indication when the session is allowed.

Abstract: A service delivery platform that can support a number of different services is provided. A context regarding an application device is received by the service delivery platform. Applications executed on the service delivery platform use the context to optimize the delivery of information to application devices.

Abstract: A mobility signaling method and apparatus are disclosed. Mobility signaling is performed by, first, generating a mobility signaling message (300, 302) at a mobile node (100) to be sent to a correspondent node (112). Next, either direct signaling or indirect signaling is selected as a signaling mechanism for the mobility signaling message (300, 302) based on a cell residence heuristic. The mobility signaling message (300, 302) is then sent to the correspondent node using the selected signaling mechanism for the mobility signaling message (300, 302).
