Abstract
A method of providing voice call, data, and SMS services to a user equipment roaming in a 2G/3G visited network and subscribed to an LTE home network. An Interworking Function communicates with both the visited network and the home network. The Interworking Function translates between Mobile Application Part (MAP) protocol used by the 2G/3G visited network and Session Initiation Protocol (SIP) used by the LTE home network. The Interworking Function establishes both a MAP Registration with the 2G/3G visited network and also a SIP Registration with the LTE home network, thereby enabling provision of voice call, data, and SMS services to the roaming UE.
