Claim 8:
9. A home controller comprising:
a memory; and
a hardware processor communicatively coupled to the memory, the hardware processor configured to:
receive, from a first device in a home domain, a first message concerning a user device that is anchored to the home domain and that has roamed from the home domain to a visited domain;
determine that the first device is a router;
in response to determining that the first device is a router:
open a tunnel between the home controller and a visited controller of the visited domain; and
communicate the first message to the user device in the visited domain through the tunnel and the visited controller;
receive a second message broadcasted by a second device in the home domain, wherein the second message concerns the user device;

determine that the second device is not a router; and
in response to determining that the second device is not a router:
generate a response to the second message; and
communicate, to the second device, the response to the second message as a proxy for the user device in the visited domain.
