A.2 Information flows
23.0663GPPRelease 17Stage 2Support of Mobile Number Portability (MNP)Technical realizationTS
In the following figures the NPDB is shown as belonging to the Number range holder network or to the national originating network. However, the NPDB may be shared within one portability domain i.e. nation-wide.
Figure A.2.1 shows the information flow for successful QoHR.
