Abstract
Abstract An International Mobile Subscriber Identity (IMSI) number transmitted by a mobile station is first analyzed by the serving mobile switching center (MSC) associated with an International Telecommunication Union (ITU)-based SS7 network. If the received IMSI number instead belongs to an American National Standards Institute (ANSI)-based SS7 network, the serving MSC prepends a country code representing the mobile subscriber to the received IMSI number. The least significant digits of the resulting number are further truncated to conform to the E.214 standard (the maximum length of fifteen digits). A Mobile Application Part (MAP) based signal, such as a location update signal, is transmitted utilizing the generated E.214 number as the Signaling Connection Control Part (SCCP) called party number parameter and routed to an international gateway connecting the ITU-T based SS7 network with the ANSI based SS7 network. The international gateway deletes the country code prepended to the IMSI number from the received MAP signal and forwards the MAP signal to the destination node within the ANSI based SS7 network.
