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.

Abstract: A method for selecting cell using a fifth generation (5G) user equipment (UE) is provided. The method includes detecting an event, when the 5G UE is camped on a serving cell; detecting availability of one or more voice over new radio (VoNR) cells and one or more non-VoNR cells in vicinity of the serving cell in response to detecting the event; based on the event, performing one of (i) selecting a VoNR cell when only one VoNR cell is available, (ii) identifying and selecting a VoNR cell based on a plurality of cell parameters, when a plurality of VoNR cells are available, and (iii) identifying and selecting a non-VoNR cell from the one or more non-VoNR cells, based on the plurality of cell parameters, when one of the one or more non-VoNR cells is available.
