Coverting a routing address within a telecommunications network
First Claim
1. A method for transmitting a signal from a first Signaling System No. 7 (SS7) network to a second SS7 network wherein said first SS7 network and said second SS7 network use an incompatible addressing mechanism, said method comprising the steps of:
- receiving at said first SS7 network a mobile subscriber identification number from a mobile station associated with a home location register (HLR) for storing subscriber information related to said mobile station and wherein said HLR is located within said second SS7 network;
prepending a particular country code associated with said second SS7 network with said mobile subscriber identification number received at said first SS7 network; and
transmitting a SS7 signal from said first SS7 network to said HLR within said second SS7 network using said prepended country code with said received mobile subscriber identification number as a routing address.

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.

10. A system for communicating a signal from a first Signaling System No. 7 (SS7) network to a second SS7 network, said system comprising:
-
a mobile station having a mobile subscriber identification number, said mobile station originally associated with said second SS7 network and currently roaming within said first SS7 network; a telecommunications node within said first SS7 network for providing mobile service to said mobile station, said telecommunications node receiving said mobile subscriber identification number from said mobile station; a first application module associated with said telecommunications node for prepending a routing number associated with said second SS7 network with said received mobile subscriber identification number; and wherein said telecommunications node transmits a SS7 signal using said prepended routing number with said mobile subscriber identification number as a called party number. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A method for communicating a signal from a first telecommunications node within a first Signaling System No. 7 (SS7) network to a second telecommunications node within a second SS7 network, said method comprising the steps of:
-
receiving an identification number associated with a particular mobile station at said first telecommunications node; determining a routing number representing said second SS7 network; transmitting a SS7 signal with said routing number and said identification number over said first SS7 network to said second SS7 network; receiving said transmitted SS7 signal at a gateway connecting said first SS7 network with said second SS7 network; removing said routing number from said received SS7 signal; and transmitting said SS7 signal with said identification number to said second telecommunications node over said second SS7 network. - View Dependent Claims (23, 24, 28, 29, 30, 31)
