SYSTEM AND METHOD FOR CALL COMPLETION TO A ROAMER WITHOUT ROUTING THROUGH THE HOME NETWORK

摘要

A telecommunications system and method is disclosed for providing an Intelligent Network (IN) solution for completing a call to a roaming mobile subscriber without routing the call through the roamer's home Public Land Mobile Network (PLMN). When a mobile subscriber is roaming in a visited PLMN, the visited network can provide a dedicated number associated with a dedicated Mobile Switching Center (MSC) that local calling party's can dial to reach the mobile subscriber without routing through the home PLMN. When a local calling party dials the dedicated number, the call is routed to the dedicated MSC, which triggers the IN. The call is then routed to an intelligent node to collect the actual directory number for the called mobile subscriber from the calling party, verify that the roaming called mobile subscriber is within the visited PLMN and complete the call via the dedicated MSC.
