ABSTRACT:
The invention provides an Intersystem Number Portability Register and a method for supporting number portability in an Intersystem Number Portability domain wherein subscribers are ported between different wireless networks based on likely different wireless systems. The Intersystem Number Portability Register is intended for use in a Number Portability resolving network, call originating or donor network, as well as for use in a recipient network. This Intersystem Number Portability Register comprise, and is intended for providing at request trouting data for home subscribers as well as for subscribers exported to, and for subscribers imported from, other wireless networks based on different wireless systems. Especially addressed to operators owning different networks based on different systems, this Intersystem Number Portability Register is extended to comprise routing data for home subscribers in different serving networks based in different wireless systems. Thereof, said operators owning different networks based on different systems may share a unique number portability database, the said Intersystem Number Portability Register, for supporting wireless number portability between said different networks based on different systems, that is, operating according to different system standards.
