Abstract: Methods and systems for ensuring continuity of services on handover from Wi-Fi to cellular networks are disclosed. Embodiments of the disclosure allow a UE to seamlessly engage in a call during a handover, which is triggered on detecting that QoS of the call is less than a threshold within a coverage area of the Wi-Fi. The continuity of the call is ensured by triggering a handover from Wi-Fi to LTE and preventing/reducing handover from Wi-Fi to NR. The UE avails calling services using LTE and data services using NR, by enabling NSA mode. The UE is allowed to avail calling services seamlessly by initiating a handover of the calling services from Wi-Fi to LTE and avail data services seamlessly by initiating a handover of the data services from Wi-Fi to NR. The handover from Wi-Fi to LTE/NR is initiated if QoS of the calling/data services is less than a threshold in Wi-Fi coverage area.
