Abstract: Methods and systems for efficient deployment of communication filters are presented. In an exemplary embodiment, a wireless communication device (WCD) attempts to register with a foreign agent and a home agent by using mobile IP. During this process, an authentication, authorization, and accounting (AAA) server receives a first message from the foreign agent, where the first message seeks to authenticate the WCD. The AAA server responds to the first message with a second message containing a filter to be applied to the WCD's communication. The AAA server than receives a third message containing the filter, and the AAA server responsively transmits a fourth message to the home agent, seeking to have the home agent apply the filter to the WCD's communication. In this way, communications between the home agent and the AAA server can be reduced because the home agent only communicates with the AAA server if the WCD is subject to a filter.
