name: VCC
full_form: Voice Call Continuity
context: VCC is a home IMS application that provides capabilities to transfer voice calls between the CS domain and the IMS. VCC provides functions for voice call originations, voice call terminations and for domain transfers between the CS domain and the IMS. This feature is defined in TS 23.206 [210]. The following principles apply to VMSC/GMSC that are capable of VCC: In case of CS Origination call with anchoring in the IMS, the Access Leg is charged as follows: Normal MOC CDR is generated by the VMSC with special handling. One example of special handling is to zero rate the CS resource usage. This can be performed using the "Service Key" parameter in the MOC Record indicating a VCC call. The CDRs generated within the IMS domain to complete the anchoring mechanism are handled as specified in TS 32.260 [55]. In case of IMS origination call, the Access Leg is charged as follows: Normal IMS and IP-CAN (e.g. WLAN or GSM/GPRS) charging mechanism are applied. These mechanisms are defined in TS
description: Voice Call Continuity (VCC) is a service that enables the transfer of voice calls between the Circuit Switched (CS) domain and the IP Multimedia Subsystem (IMS). It provides capabilities for voice call originations, terminations, and domain transfers between the CS domain and the IMS.
explanation: The text describes VCC as a service that offers specific functionalities related to voice call management across different network domains. This aligns with the definition of a 'Service' in telecommunications, which refers to offerings that provide distinct capabilities or functions.
