4. The method of claim 1 wherein selecting a GTT mode from a plurality of different GTT modes based on an attribute of the received signaling message includes selecting a GTT mode based on at least one of an incoming linkset of the received signaling message and an address parameter of the received signaling message.
1. A method for global title translation (GTT) in a telecommunications network, the method comprising: (a) receiving a signaling message that contains a global title address (GTA); (b) selecting a GTT mode from a plurality of different GTT modes based on an attribute of the received signaling message, wherein at least some of the different GTT modes use different combinations of address parameters associated with received signaling messages to search a GTT database, and wherein each of the different GTT modes uses at least a signaling connection control part (SCCP) parameter from the received signaling message to determine at least a message transfer part (MTP) destination point code; and (c) searching the GTT database using a combination of address parameters of the received signaling message specific to the selected GTT mode.
