Abstract
A system and method for connecting a call processes call signaling to determine if a call is a ported call or a non-ported call. A signaling processor determines if a ported number parameter (PNP), such as a forward call indicator (FCI) bit M and/or a ported number generic address parameter (GAP), is present. If the PNP is not present and the signaling processor determines the dialed number is a member of a portable number plan area and central office code combinations (NPA-NXX), the signaling processor queries a ported number database (PNDB). The PNDB responds with the called number dialed digits if the call is not a ported call or a location routing number (LRN) if the call is a ported call. The signaling processor appends a 1 to the nature of address (NOA) subfield of the called party number (CdPN) field if the call is a ported call. The signaling processor then partitions the call signaling parameters between ported or non-ported routing table translations, depending on whether the NOA is appended or not, to determine call routing connections and new call signaling. The appended 1 of the appended NOA is removed prior to building an outgoing call signaling message.
