Methods and systems for efficient deployment of communication filters

A server comprising:

• a processor;
• a data storage containing a profile associated with a wireless communication device (WCD), wherein the profile indicates that the WCD is to be subject to, at a home agent, a filter, wherein the filter represents rules for the home agent to apply to data packets of the WCD's communication;
• program instructions, stored in the data storage and executable by the processor, to (i) receive a first message from a foreign agent, wherein via the first message the foreign agent seeks to authenticate the WCD, (ii) responsive to receiving the first message, determine that the WCD is to be subject to, at the home agent, the filter, (iii) responsive to determining that the WCD is to be subject to, at the home agent, the filter at the home agent, transmit a second message to the foreign agent, wherein the second message includes an attribute that contains a representation of the filter, (iv) receive a third message from the foreign agent, wherein the third message contains (a) accounting information associated with the WCD, (b) an address of the home agent, and (c) the attribute that contains the representation of the filter, and (v) responsive to receiving the third message, transmit a fourth message to the home agent, wherein the fourth message contains the representation of first filter and requests the home agent to apply the filter to at least some communications associated with the WCD, such that the home agent does not perform home agent authentication for the first WCD.
