Abstract
An application server provides communication services via a packet-switched network to mobile nodes based on their respective registrations in a registry, such as a home subscriber server (HSS) or domain name server (DNS). A registration proxy may be used to effect a registration in the registry on behalf of a mobile node when the mobile node lacks sufficient capability to effect the registration itself. The registration proxy may perform this function after receiving a notification that the mobile node is connected to the packet-switched network and after querying a capabilities server to determine that the mobile node lacks sufficient registration capability. To effect a registration in an HSS, the registration proxy may emulate either a serving call state control function (S-CSCF) or user equipment (UE).
