Abstract: The present disclosure relates to a method and a system for Non-3GPP Interworking Function (N3IWF) selection in a UE for network connectivity. The method comprising receiving, by the UE associated with the system, a configuration message from an AMF in a network. Thereafter, the method comprising configuring each of a plurality of N3IWF identifiers and associated at least one S-NSSAI present in the configuration message, wherein the each of the plurality of N3IWF identifiers is an IP address or a FQDN. Subsequently, the method comprising selecting a N3IWF identifier from the plurality of N3IWF identifiers based on a user selection of a S-NSSAI associated with the N3IWF identifier for the network connectivity. The present disclosure makes user aware of the different N3IWFs available in the network, which allows user to select right N3IWF, and hence, the services the user wants to utilize while connecting via non-3 GPP network.

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: The present disclosure relates to the field of network slicing in wireless communication. In accordance with an aspect of the disclosure, a method performed by an access and mobility function (AMF) entity is provided. The method includes receiving, from a user equipment (UE), a registration request including a requested network slice selection assistance information (NSSAI); transmitting, to a Network Slice Admission Control Function (NSACF) entity, a request for determination of an availability of a number of UEs based on the registration request; and in case that a rejection for the request is received from the NSACF, transmitting, to the UE, information on a back-off timer.

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.
