2.7 Interactions of Operator Determined Barring with Supplementary Services |R4| p. 24
The following interactions of Operator Determined Barring with supplementary services have been identified:
2.7.1 Call Forwarding p. 24
The interactions between Operator Determined Barring and Call Forwarding are specified in TS 22.041.
The interaction where Operator Determined Barring is applied when there is an existing Call Forwarding programme which is in contravention of the Operator Determined Barring programme is shown in the message flow diagram in Figure 2.7.1-1. The HLR modifies the subscription information for the mobile subscriber to show that the contravening call forwarding programme is quiescent, and forwards the modified subscription information to the VLR. No indication is forwarded to the mobile station or the user.
