1. A method of provisioning a subscriber profile into a subscriber data store of an IP Multimedia System (IMS)-capable telecommunications network, wherein the subscriber profile is for a visiting subscriber with respect to the IMS-capable telecommunications network, and wherein the subscriber data store is for use in IP Multimedia System (IMS) call processing, the method comprising:
receiving, by a modified Serving Gateway and Packet Data Network Gateway (SGW/PGW), a request to allocate an IMS Access Point Name (APN);
in response to receiving the request to allocate the IMS APN, triggering, by the modified SGW/PGW, a provisioning of the subscriber profile into the subscriber data store by transmitting a notification to a Visitor Location Register Application Server (VLR AS);
in response receiving the notification, transmitting by the VLR AS, a request to provision the subscriber profile into a Home Subscriber Server (HSS) of the IMS-capable telecommunications network; and
triggering, by the VLR AS, a location update in a home location register (HLR) of a home network of the visiting subscriber;
wherein the modified SGW/PGW is operable to simulate a 2G/3G Mobile Switching Center and Visited Location Register (MSC/VLR) to the home network.
