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: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein disclose a method for handling a deregistration procedure of a UE (100) for a disaster roaming service in a wireless network (1000) by the UE (100). The method includes detecting a disaster condition in the wireless network (1000). Further, the method includes triggering a registration procedure with a forbidden PLMN (FPLMN) on a 3GPP access to receive the disaster roaming service in the wireless network (1000) and get registered for the disaster roaming service with the FPLMN (300). Further, the method includes detecting a signal on a non-3GPP access to receive a normal service. Further, the method includes triggering a deregistration procedure with the FPLMN (300) on the 3GPP access to stop receiving the disaster roaming service from the FPLMN (300) in response to detecting the signal on the non-3GPP access to receive the normal service.

Abstract: Present disclosure relates to a method and a UE for releasing PDU session. The UE identifies that the UE is in a restricted service area. Upon identifying that the UE is in the restricted service area, the UE releases PTI allocated by the UE and performs a local release of the PDU session. Further, the UE provides, to a network, information related to the PDU session, based on a subsequent trigger of a registration procedure.

Abstract: A method for managing a Protocol Data Unit, PDU, session at a terminal in a mobile communications network, the method comprising: receiving, from the mobile communications network, a PDU session management message associated with a PDU session; determining, based on a type of the PDU session, whether the PDU session management message includes an operation related to an invalid PDU session parameter, and if the PDU session management message includes an operation related to an invalid PDU session parameter, rejecting the PDU session management message, releasing the PDU session, or modifying the PDU session.

Abstract: A method, for a UE in a network, for requesting an emergency service is disclosed. The method comprises: when an emergency service is required, if the UE is using CP CIoT optimization, transmitting a NAS message including an indication that an emergency service is requested. The NAS message may be a CPSR message, and the indication may be a predetermined value (e.g. denoting “emergency service”) in a predetermined field (e.g. Control plane service type field) of the message. Alternatively, the NAS message may be a Service Request message, the indication may be a predetermined value (e.g. denoting “emergency service” or “emergency service fallback”) in a predetermined field (e.g. Service type field) of the message, and transmitting the Service Request message may be prioritised over transmitting a message (e.g. CPSR message) for sending data (e.g. not related to an emergency service).

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).
