Abstract:
A method of auditing Local Number Portability (LNP) data including ported telephone numbers deployed from a Local Service Management System (LSMS) to a primary LNP network element and a backup LNP network element in a telecommunications network, said LSMS including a Number Manager with a LNP database and a Service Management Application System (SMAS), said method comprising the steps of:sending an audit request from the Number Manager to the SMAS, the audit request including telephone numbers to be audited in the LNP primary network element and the backup LNP network element;transmitting a first retrieval message from the SMAS to the primary LNP network element, said first retrieval message including a range of sequential telephone numbers in a single message, and requesting the primary LNP network element to retrieve and report the LNP data associated with each telephone number in the range;transmitting a second retrieval message from the SMAS to the backup LNP network element, said second retrieval message including the range of sequential telephone numbers in a single message, and requesting the backup LNP network element to retrieve and report the LNP data associated with each telephone number in the range;reporting from the primary LNP network element and the backup LNP network element to the SMAS, the LNP data associated with each telephone number in the range;determining in the SMAS whether the LNP data reported by the primary LNP network element is consistent with the LNP data reported by the backup LNP network element; andreporting an inconsistency to a network operator, upon determining that the LNP data reported by the primary LNP network element and the backup LNP network element are inconsistent.
