In a PLMN using a MNP-SRF based MNP solution supporting direct routeing, the INE always sends the MNP information request, containing the CdPA, to the MNP-SRF in that network.
The INE may query the MNP information for the called party number or the calling party number.
The INE requesting MNP information may be a gsmSCF for prepaid services (see TS 23.078).
In order to provide enough information for a CAMEL SCP to charge correctly for CAMEL Pre-Paid Calls and SMS to national MSISDNs originated in the HPLMN, operators should ensure that the NPDB contains, at least, MNP information for 'own numbers ported out' and 'foreign numbers ported in'.

The Interrogating Network Entity (INE) submits a MNP Information request message to the MNP-SRFB, which triggers MNP-SRF operation. The MNP-SRF functionality analyses the MSISDN in the application level and queries an MNP database to get the MNP information. The INE may query the MNP information for the called party number or the calling party number.
The INE requesting MNP information may be a gsmSCF for prepaid services (see TS 23.078).
