A mobile communication terminal includes a registration module that initiates a registration of the mobile communication terminal with Internet protocol (IP) multimedia subsystems (IMS) within a home network. The registration module initiates registration when the mobile communication terminal is roaming in a visited network. The mobile communication terminal also includes a session module that initiates a session set-up with the IMS to enable use of IMS resources. At least one of the registration module and the session module provide a first IP address to the IMS during at least one of the registration and the session set-up. The mobile communication terminal communicates with a first packet data network (PDN) that is local to the visited network using the first IP address in order to use at least one of the IMS resources.
