Abstract
A telecommunications system and method is disclosed for providing service transparency for mobile terminating calls to a roaming H.,mobile terminal. An H.,mobile terminal can be assigned both an office number and a regular Mobile Station Integrated Services Digital Network (MSISDN) number. The MSISDN of the H.,mobile terminal will not be made available to the H.,mobile subscriber or to anyone else. The MSISDN will only be used internally within the Public Land Mobile Network (PLMN) and H.,system to route the call properly. Thus, whenever a call attempt is made to the H.,mobile terminal, the call shall always be routed to the H.,Gatekeeper. If the H.,mobile terminal has roamed outside the H.,network, the H.,Gatekeeper can apply mobile terminating services to the incoming call and route the call to the serving PLMN of the H.,mobile terminal using the H.,mobile terminal's MSISDN.
