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

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

  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. 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. Domain Transfer Function DTF Domain Transfer: • Enablement: iFC execution envokes DTF • Execution: consists of3 steps
