Method and system for providing local telephone number portability using geographic unit building blocks
First Claim
1. A method for processing calls in a telephone network enabled to provide service and location number portability both within and outside a Rate Center, said method comprising the steps of:
- accessing a pre-query routing database to rate a called party telephone number;
sending a query from an originating switch to a local number portability database requesting a location routing number wherein said query includes said called party telephone number;
finding in said local number portability database the location routing number associated with said called party telephone number;
sending a response from said local number portability database to said originating switch wherein said response includes said location routing number;
accessing a post-query routing database to rate said called party telephone number; and
routing said telephone call to a destination switch based on said pre-query rating, on said post-query rating, and on said location routing number.

Abstract
A method and system for providing local number portability using a concept known as Geographic Unit Building Blocks (GUBB). Service providers (carriers) accept and use a map that divides a geographic area, such as a State, into sub-area GUBBs. The carriers operating within the State jurisdiction would then assign GUBBs to the telephone numbers they serve which accurately reflect each telephone number'"'"'s geographic location on the State map. All ported numbers will have an explicit GUBB assignment as part of the location routing number (LRN) which would then be stored in the Local Number Portability (LNP) database used to provide translations for routing the call.
