Abstract
A method and system for increasing compatibility among telecommunications networks using different types of signaling systems. Current location information for a mobile station is stored in a register. Subsequently, a telecommunication node attempting to access the mobile station requests current location data from the register. It is determined, however, that the stored location information is incompatible with a signaling system used by the telecommunication node. As a result, a physical address that corresponds to the stored location information is identified as being compatible with the signaling system. The identified physical address is then used to perform the access of the mobile station. In accordance with one embodiment of the invention, the attempted access of the mobile station is for purposes of delivering a short message service (SMS) message. In another embodiment, the attempted access comprises an attempt to set up an international call connection.
