Abstract
Provided is a method and system for minimizing call setup delay in a network. The system includes a central node that may be connected to multiple home location registers (HLRs) and a number portability database (NPDB). The central node may also be associated with two tables. The first table includes mobile station identifiers and associated location routing numbers (LRNs), and the second table includes mobile station identifiers and associated home location registers (HLRs). The method searches the first and second tables for a mobile station identifier that matches a mobile station identifier associated with a call. If a match is found, the method uses the associated LRN or HLR to continue with the call setup or to obtain further information. If no match is found, the method sends a query to the NPDB. The method may also dynamically update the first and second tables as current information is obtained.
