    Abstract: A method of handling an ongoing call performed by a UE in a wireless network is provided. The method includes initiating a voice over long term evolution (VoLTE) call in a 4th generation (4G) network, detecting that a 5th generation (5G) network entity has configured an inter radio access technology (I-RAT) measurement indicating a change from the 4G network to a 5G network based on identification of the 5G network by the UE, determining whether at least one of the UE or the 5G network does not support a voice over new radio (VoNR) call with a 5G cell in the 5G network, and performing one of delaying sending a measurement report until the VoLTE call is completed in response to determining that the at least one of the UE or the 5G network does not support the VoNR call, or sending the measurement report immediately for the 5G cell in response to determining that both the UE and the 5G network support the VoNR call.

    Abstract: A method for connecting user equipment (UE) to data network name (DNN) in public network integrated non-public network (NPN) is provided. The method includes identifying prioritized DNN and corresponding network slice, from list of prioritized DNNs and network slices, when UE (moves from first location to second location, where session management (SM) retry timer is enabled, disabling SM retry timer based on identification, evaluating user route selection policy (URSP) rule for connecting UE to prioritized DNN and corresponding network slice. Further, the disclosure relates to method receiving rejection cause when UE sends request to connect to higher priority DNN and via corresponding network slice, where SM retry timer is enabled, detecting inactivity of packet transmission for pre-determined time period, and evaluating URSP rule, where UE is connected to higher priority DNN, and corresponding network slice.

    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services.The various embodiments of the present invention disclose a method of handling control plane data in a wireless network, the method comprises sending, by a user entity (UE), a non-access stratum (NAS) message along with an indication data to a mobility management (MM) core network entity. The MM core network entity processes the received NAS message and the indication data. The MM core network entity determines status of network congestion upon processing the processed NAS message. Sending, by the MM core network entity, a response to the UE based on at least one of the processed indication data and the determined network congestion.

    Abstract: Embodiments herein provide a method for controlling disaster area for disaster roaming service by a UE (100). The method includes detecting a disaster condition associated with a first PLMN (200a) that is associated with a first service provider. Further, the method includes sending a registration request to a second PLMN (200b) for the disaster roaming service. The second PLMN (200b) is associated with a second service provider and is available in a disaster area covered by the first PLMN (200a). Further, the method includes receiving a TAI list from the second PLMN (200b). The TAI list includes a set of tracking areas associated with the disaster area covered by the second PLMN (200b). Further, the method includes camping on the second PLMN (200b) for the disaster roaming service in the set of tracking areas indicated in the TAI list during the disaster condition with the first PLMN (200a).

    Abstract: Embodiments herein disclose methods for handling operation of a UE during a disaster situation by the UE. The method includes initiating a wait timer upon selecting a forbidden public land mobile network (FPLMN) to receive a disaster roaming service. Further, the method includes determining whether at least one of: a MS is registered via a non-3GPP access or 3GPP access to another allowable PLMN, the FPLMN has stopped broadcasting a disaster related indication, and the FPLMN has stopped broadcasting the PLMN with the disaster condition. Further, the method includes stopping the wait timer and performing a PLMN selection procedure based on the determination. The provided method optimizes the operations in disaster situations.

    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The embodiment herein is to disclose a method for selecting PLMN with disaster condition (PLMN-D) to receive disaster roaming service in an area. The method includes detecting, by a UE, a disaster condition in the area. Further, the method includes detecting, by the UE, a forbidden PLMN (FPLMN) broadcasting a plurality of PLMN-Ds in the area. Further, the method includes selecting, by the UE, the at least one PLMN-D from the plurality of PLMN-D based on a predefined sequence of priority order. Further, the method includes camping, by the UE, the FPLMN corresponding to the at least one selected PLMN-D. Further, the method includes triggering, by the UE, a registration procedure on the camped FPLMN by indicating the at least one selected PLMN-D in the registration request message.
