Number portability database

摘要

It is an object of the invention to provide a Number Portability Database, which provides access for different signaling application services for fixed and/or mobile users independently from the topology of the network. An inventive number portability database includes e.g. a E.164 single number configuration table, a E.164 range number configuration number table, and a service control configuration table. Each configuration table includes several parameters and can easily be re-configured allowing the whole system to be very flexible and to be adapted to specific requirements via simple software reprogramming. If predefined parameters of an assembled search digit string (e.g. assembled from a received E.164 number) could not be found in a Single Number Configuration Table a further query is done in a Range Number Configuration Table. This two step approach enables a quicker search routine. Parameters are e.g. number value, portability status, transition indicator, service control.
