Embodiments herein is to provide a method for providing user consent for UE in a 5G network (1000) by a UE (300). The method includes receiving a request message from a network apparatus (200) to check with the UE (300) whether the network apparatus (200) can provide subscribed event information to a NWDAF (100). The request message includes the subscribed event information and a consumer NF ID to obtain consent from the UE (300). Further, the method includes determining, by the UE (300), using the preconfigured data whether a consent can be provided for the subscribed event information to the NWDAF (100). Further, the method includes sending, by the UE (300), a response message to the network apparatus (200), wherein the response message comprises a consent indication allowing the network apparatus (200) to provide the subscribed event information to the NWDAF (100).

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 method includes comparing plurality of parameters (e.g. TAI) received in message (e.g. initial NAS message, registration request, first protected NAS message) from UE and plurality of parameters (e.g. TAI) broadcasted/received/stored by AMF entity and/or genuine gNB. AMF entity and/or genuine gNB sends an accept message (e.g. NAS accept) or reject message (e.g. NAS reject, RRC reject or RRC reconfiguration.) with appropriate error cause value to UE to mitigate the MitM attack. Based on received message from AMF entity and/or genuine gNB, UE detects that UE is camped on genuine gNB or fake gNB. UE performs action(s) (e.g. cell reselection), when UE is camped on fake gNB/eNB to mitigate MitM attack.

Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE).
Embodiments herein disclose a method performed by a terminal in a mobile communication system. The method includes performing a registration procedure on a first standalone non-public network (SNPN), selecting a second SNPN based on a predetermined condition, and transmitting, to a network entity, a registration request message on the second SNPN for an initial registration, in case that the second SNPN differs from the first SNPN.
