| Voice and video call continuity over LTE, Wi-Fi and 2G/3G |
 |
This Recommendation specifies the voice and video call continuity (VCC) over LTE, Wi-Fi and 2G/3G. The scenarios and relevant requirements are specified, as well as the solutions for access transfer between each of the access types, handover policy, terminating access domain selection (T-ADS), evolved packet data gateway (ePDG) selection and other call continuity related solutions. |
