B.3.1 Procedure MNP_SRF_Non_Call_Related

Figure B.3.1 shows the procedure MNP_SRF_Non_Call_Related. This procedure handles non-call related signalling messages. It is called from the process MNP_SRF (see clause 4.3).

The check "CdPA contains own number ported out?" identifies all mobile numbers from number ranges allocated to the network the MNP-SRF is located in and which are ported to other networks. In this case the message is relayed to the subscription network.

The check "CdPA contains own number not ported out?" identifies all mobile numbers from the number ranges allocated to the network the MNP-SRF is located in and which are still served by the network the MNP-SRF is located in, i.e. the numbers are not ported out. In this case the message is relayed to the HLR in the network.

The check "CdPA contains foreign number ported in?" identifies all mobile numbers from the number ranges not allocated to the network the MNP-SRF is located in and which are served by the network the MNP-SRF is located in, i.e. the numbers are ported in. In this case the message is relayed to the HLR in the network.

The check "CdPA contains foreign number ported to a foreign network?" identifies all mobile numbers from the number ranges not allocated to the network the MNP-SRF is located in and which are not served by the MNP-SRF is located in and not served by the network the number range is allocated to, i.e. the numbers are ported to a foreign network. In this case the message is relayed to the subscription network.

The remaining numbers "CdPA contains number not known to be ported ?" are mobile numbers from the number ranges not allocated to the network the MNP-SRF is located in and which are also not served by the network the MNP-SRF is located in. In this case the message is relayed to the number range holder network.
