10.2 Call forwarding services

10.2.1 Registration of Call Forwarding

The functional behaviour for the registration of the Call Forwarding supplementary service is defined in 3GPP TS 03.82 [13]. The procedure specific to CAMEL is defined in this subclause:

– CAMEL_Check_CF_Interaction

10.2.2 Invocation of Call Forwarding

The functional behaviour for the invocation of the Call Forwarding supplementary service is defined in 3GPP TS 03.18 [3]. The following additional requirements apply.

When call forwarding is invoked for a CAMEL subscriber with O-CSI, the gsmSSF shall send the FTN to the gsmSCF in the format in which it was received from the HLR.

An HLR shall not send an FTN which is not in international E.164 format to a VLR or GMSC which does not support CAMEL phase 2, i.e.:if the HLR is handling a request from a GMSC for routeing information and the forwarded-to number is registered a format other than international E.164, the service logic in the HLR shall behave as if the call forwarding is provisioned but not registered.

10.3 Call Barring services

When a CAMEL subscriber with O-CSI and TIF-CSI attempts to activate a conditional call barring service (BOIC,BOIC-exHC), the HLR shall not check the interactions with call forwarding.
