    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 method includes configuring, by a User Equipment (UE) (100), a Protocol Data Unit (PDU) session type as an always-ON type or a normal PDU type. Further, the method includes sending, by the UE (100), a PDU session establishment request message including the PDU session type to be the always-ON type or the normal PDU type to a network (200) during an initial PDU session establishment procedure.

    Abstract: Accordingly, embodiments herein provide a system for managing anti-steering of roaming in a wireless communication network. The system includes a HPLMN, a VPLMN and a UE. The HPLMN obtains a register request message from the VPLMN and IN derives at least one HPLMN specific security key based on at least one security parameter. Further, the HPLMN protects a preferred PLMN list using the at least one HPLMN specific security key and the security parameter and sends the protected preferred PLMN list to the VPLMN along with necessary security information. Further, the VPLMN is configured to receive the protected preferred PLMN list from the HPLMN and send a message including the protected preferred PLMN list to the UE. The message mandates the VPLMN to send the preferred PLMN list transparently to the UE. Further, the UE is configured to receive the message including the preferred PLMN list from the VPLMN.

    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 provide a method and an apparatus for managing a non-integrity protected message. The method includes receiving a reject cause message from a first public land mobile network (PLMN) in response to a transmission of a registration request message to the first PLMN, re-attempting the transmission of the registration request message to one of the first PLMN and a second PLMN, receiving registration accept message from one of the first PLMN and the second PLMN in response to the re-attempting, and resetting a counter maintained for the first PLMN by the UE.

    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 timer expiry during an ongoing non-access stratum (NAS) procedure in a wireless network by a UE. The method includes detecting that a last running first timer is stopped or expired. Further, the method includes performing a deregistration procedure by sending a deregistration request message to a network entity in the wireless network when the last running first timer is stopped or expired. Further, the method includes starting a second timer. Further, the method includes determining that the deregistration procedure is not successful in first attempt. Further, the method includes aborting the ongoing deregistration procedure upon determining that the deregistration procedure is not successful in the first attempt. The method can be used to ensure that the UE registers over higher priority PLMN without any delay and extra signalling.
