Abstract
This invention provides a means and method for updating two-tiered databases in a telecommunications system which support local number portability through call connection information sets stored on the databases. Pro-active updating is accomplished by tracking location, time and frequency of each switch querying the first tier centralized database for each stored call connection information set. At the time an update is made to a call connection information set at the first tier database, the set is offered to all second tier databases supporting individual switches which have queried the centralized database for that set. Second tier databases accept the set as an update, a new set or reject. Acceptance of a new set or rejection is dependent upon the set achieving a ranking based on recency and frequency of query above the threshold for storage. The second tier databases provide confirmation of set acceptance and rejection to the first tier database.
