ABSTRACT:
A method of routing an interim NP call in which it is determined to give a called number interim NP redirection rather than conventional RCF redirection when the called number is to be ported. When a ported call is to receive interim NP redirection and SS7 networking is used, an Initial Address Message for the call is created with the Called Party Number parameter of the Initial Address Message populated with the Location Routing Number for the switch to which the called number has been ported. The Generic Address Parameter of the Initial Address Message is populated with the called number and the M bit of the Forward Call Indicator parameter of the Initial Address Message is set. The call is then redirected to the switch to which the called number has been ported based on the Location Routing Number in the Called Party Number parameter of an Initial Address Message. This method avoids the use of RCF "shadow numbers" and the need to query an external long-term NP database.
