摘要
A telecommunications system and method for managing Local Number Portability (LNP) querying for calls routed to Interexchange Carriers by providing a list of carriers in the Service Switching Point (SSP) (local service provider) for whom LNP querying is to be performed by the SSP. For example, calls destined to carriers on the list will be queried by the originating SSP, or other intermediate SSP, and calls destined for carriers not on the list will not be queried by the originating SSP, but instead will be directly routed to the carrier for LNP querying. Advantageously, the local service providers (SSPs) can perform LNP queries for calls destined to certain carriers and charge them for the queries. This will enable small long-distance carriers to provide competitive service in the network by purchasing the LNP querying facility from the SSPs. Furthermore, LNP querying will now be able to be provided for every call routed through an Interexchange Carrier (IXC), regardless of whether the IXC has LNP querying capability.
