A.2 Information flows

03.663GPPStage 2Support of GSM Mobile Number Portability (MNP)TS

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.
