7.12.1 Roaming into a network not supporting CAMEL Phase 3
When roaming into a network not supporting CAMEL Phase 3, only the functionality of MSP Phase 1 will be available to an MSP subscriber.
The default profile subscription information shall apply to all supplementary services, excluding Call Forwarding and Call Barring, provisioned per profile.
7.12.2 Roaming into a network not supporting CAMEL Phase 2
This clause details MSP specific handling for roaming into a network not supporting CAMEL Phase 2. Other handling for this scenario is described in 3G TS 23.078.
18.104.22.168 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.
22.214.171.124 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.
126.96.36.199 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.
188.8.131.52 MO short message handling
MO short messages will be sent from and charged to the default profile.
7.12.3 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.
