7.10.1 Roaming into a network not supporting CAMEL Phase 2

This subclause details MSP specific handling for roaming into a network not supporting CAMEL Phase 2. Other handling for this scenario is described in GSM 03.78.

7.10.1.1 Actions required on Location Update

The HLR will send the outgoing call barring data and outgoing ODB data, specific to the default profile, to the VLR.

7.10.1.2 MO call handling

When an MSP subscriber roams into a network not supporting CAMEL Phase 2, the default profile will be used for all outgoing traffic.

7.10.1.3 MT call handling

MT calls to any profile will be received by the subscriber (subject to call forwardings and call barrings provided in the gsmSCF on the called profile), although no indication of the called profile will be received.

The HLR will not allow OR, this means that for MT calls, the GMSC will always support CAMEL Phase 2, allowing the gsmSCF to invoke appropriate Call Forwardings and Call Barrings.

7.10.2 Lack of availability of the Network Indication of Alerting feature

If an MSP subscriber roams into a network not supporting the Network Indication of Alerting feature, or is using an MS that does not support the Network indication of Alerting feature, then the subscriber will still receive all MT calls, but no indication of the called profile will be given.
