Abstract
A telecommunications network ( ) includes a signal transfer point ( ) that receives an initial address message from a service switching point ( ). The signal transfer point ( ) determines whether a Forward Call Identifier (FCI) “m” bit has been set indicating that a local number portability (LNP) query has been performed. If the FCI “m” bit has been set, then the signal transfer point ( ) performs normal call processing. If the FCI “m” bit is not set, the signal transfer point ( ) will set the FCI “m” bit to one prior to performing normal processing if a database interrogation is not activated. If database interrogation is activated, the signal transfer point ( ) interrogates a LNP database to determine whether the dialed subscriber has been ported and/or resides in a receiving network. The signal transfer point ( ) will set the FCI “m” bit in response to either the dialed subscriber not being ported or not residing in the receiving network prior to normal processing. The FCI “m” bit will remain at a zero state if the dialed subscriber has been ported and resides in the receiving network.
