2 2 VCC UE Stores: domain selection policies, domain transfer restrictions Selects: domain Initates: Domain Transfer

3 3 Domain Selection Function DSF Determines: the IMS / CS registration status Communicates: with the DTF Determines: the CS Domain Routing Number

4 4 CS Adaption Function Identifies: the VCC user Communicates: call related data from CS to IMS Managed: IMS Routing Number (IMRN) Behaves: as a SIP UA

5 5 CAMEL Service Enforces: CS redirection policy Communicates: call related data from CS to IMS Re-Routes: CS calls to the IMS Resolves: VCC Application PSI from VDN

6 6 Domain Transfer Function DTF Domain Transfer: Enablement: iFC execution envokes DTF Execution: consists of 3 steps
