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. Disclosed is a method of operating a User Equipment, the UE being operable in a first mode or a second mode, and being further operable to communicate with a telecommunication network, wherein in the first mode (EPS/S1) if: the UE receives a SERVICE ACCEPT message: the UE has set a Control plane service type of a CONTROL PLANE SERVICE REQUEST message to “mobile terminating request” and an “active” flag in the Control plane service type Information Element, IE, to 0); User Plane, UP, radio bearers have not been set up; and the CONTROL PLANE SERVICE REQUEST message was sent from EMM-IDLE mode, then the UE starts a timer to guard a time during which the UE remains in connected mode; and in the second mode (5GS/N1) if: the UE sends a CONTROL PLANE SERVICE REQUEST message; the UE did not set a Control plane service type IE to “emergency services fallback”; the UE has not included an Uplink data status IE in the CONTROL PLANE SERVICE REQUEST message, or the UE has included the Uplink data status IE in the CONTROL PLANE SERVICE REQUEST message but a received SERVICE ACCEPT message indicates that no user-plane resources of any PDU sessions are to be re-established, then the UE starts a timer to guard a time during which the UE remains in connected mode.

Abstract: The disclosure relates to 5G or 6G communication system for supporting a higher data transmission rate. In an embodiment, a method includes deciding to use 3GPP access or non-3GPP access; and based on the decision, transmitting a service request message or a registration request message to an access and mobility management function (AMF) over the 3GPP access or the non-3GPP access, wherein in case that paging restriction information is not included in the service request message or the registration request message transmitted over the 3GPP access, stored paging restriction information regarding context of the UE is removed at the AMF.
