Abstract: A method for random access channel (RACH) procedure in a wireless network by a user equipment (UE) is provided. The method includes determining a plurality of signal condition parameters associated with the UE. Further, the method includes determining whether at least one signal condition parameter of the plurality of signal condition parameters meets at least one signal condition threshold from a plurality of signal condition thresholds. Further, the method includes triggering one of a 2-step RACH procedure in response to determining that the at least one signal condition parameter of the plurality of signal condition parameters meets the at least one signal condition threshold, or a 4-step RACH procedure in response to determining that the at least one signal condition parameter of the plurality of signal condition parameters does not meet the at least one signal condition threshold.

Abstract: The present subject matter refers a method of cell selection and reselection. The method comprises detecting a plurality of neighboring cells and their associated plurality of cell capabilities while the UE, having an associated UE capability, is connected to a serving cell. A possible throughput for the plurality of neighbouring cells is determined based on the detected plurality of cell capability and UE capability. A first neighboring cell is selected from the plurality of neighboring cells based on the determined possible throughput.

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.

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: Embodiments herein provide a method for performing voice call performance by a user equipment (UE). A voice call is preferred for a cellular network over a Wi-Fi network, an IMS is registered over a 5G BS, the 5G BS is not supported for the voice call, and a Wi-Fi device and a 4G BS are supported for the voice call. The method includes: detecting an event related to the voice call; comparing signal strength of the Wi-Fi device and signal strength of the 4G BS; shifting an IMS registration from the 5G BS to the Wi-Fi device, upon determining that the signal strength of the Wi-Fi device is greater than the signal strength of the 4G BS; and initiating the voice call over the Wi-Fi device upon detecting a trigger for the voice call.
