Voice Call Continuity (VCC) is a telecommunication feature that allows for seamless transitioning of voice calls between different networks or technologies. It ensures that ongoing voice calls remain connected and uninterrupted when a user moves between different network environments, such as switching from a cellular network to a Wi-Fi network or vice versa.

The main goal of VCC is to provide a seamless user experience by enabling voice calls to continue without any disruption or call drops. It allows users to initiate a call on one network and seamlessly transfer it to another network without interruption. For example, if a user starts a voice call on their mobile phone using cellular network connectivity and then moves into an area with Wi-Fi coverage, VCC enables the call to seamlessly transition to the Wi-Fi network without the user experiencing any call drops or quality degradation.

VCC typically involves the integration of different network technologies, protocols, and systems to facilitate the seamless handover of voice calls. It requires coordination and cooperation between the involved networks and service providers to ensure smooth transitioning of the call without affecting call quality or user experience.

The benefits of Voice Call Continuity include:

  1. Seamless Mobility: Users can enjoy uninterrupted voice calls while moving between different networks, such as cellular and Wi-Fi, without the need to manually disconnect and reconnect the call.
  2. Enhanced Coverage: VCC expands the coverage area by leveraging available networks, allowing users to make and receive voice calls even in areas with limited cellular coverage but with Wi-Fi connectivity.
  3. Quality and Reliability: Voice calls transferred using VCC maintain their quality and reliability during the handover process, ensuring clear and uninterrupted communication for users.
  4. Cost Optimization: VCC can help reduce call costs by utilizing cost-effective networks, such as Wi-Fi, when available, instead of relying solely on cellular networks.

Voice Call Continuity is an important feature in today’s mobile and connected world, enabling users to stay connected and communicate seamlessly regardless of the network environment they are in. It contributes to a better user experience and ensures reliable voice communication across various network technologies.
