Abstract: Embodiments herein provide methods and systems for performing paging operation in 5G communication networks. The 5G core network can transmit a NAS message to a UE through a N3GPP access network, if the UE is reachable through the N3GPP access network. The NAS message can be sent by the 5G core network to the N3IWF. The N3IWF can send the NAS message to the UE, through the N3GPP access network. The UE can send a service request over 3GPP access, in response to the NAS message, to the 5G core network, through a 5G RAN. If the UE is not having access to the 5G RAN, then the UE can transmit a notification response message to the 5G core network, indicating the inability to transmit a service request. The transmission of NAS message through the N3IWF can lead to a significant saving of radio resources.

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.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein provide a method for handling registration of a UE (100) for disaster roaming service in a network (1000) by a second PLMN (200b). In an embodiment, the method includes sending a registration reject message to the UE (100) in response to determining that the UE is not allowed to receive the disaster roaming service, with a first PLMN as PLMN with the disaster condition, from the second PLMN. In another embodiment, the method includes determining whether the second PLMN (200b) provides the disaster roaming service or a normal service to the UE (100) in response to determining that the UE is allowed to receive the service from the second PLMN (200b), and sending a registration accept message to the UE (100).
