Abstract: Embodiments herein provide a method and a wireless network device (100) for handing a paging cause of a service. The method includes receiving, by the wireless network device (100), a NAS message includes the paging cause of the service provided by the wireless network device (100) and a first value corresponding to the paging cause from a UE (200). The method includes modifying, by the wireless network device (100), the first value of the paging cause of the service to a second value, and sending a NAS response message to the UE (200), where the NAS response message includes the paging cause of the service and the second value of the paging cause. The second value enables the UE (200) to respond to a paging message based on the second value of the paging cause.

Abstract: The 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 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. A method disclosed herein includes storing, by a network, URC identifiers (IDs) against all Public Land Mobile Network-Identifiers (IDs) belonging to a same Tracking Area Identity (TAI) list in a UE context information. The method further includes identifying, by a network, a mobility of the UE from a source PLMN ID to a target PLMN ID and indicating the URC ID of the target PLMN ID to a Radio Access Network (RAN) associated with the target PLMN based on the UE context information, if the source PLMN ID and the target PLMN ID belong to the same TAI list.

Abstract: Embodiments of present disclosure relates to an apparatus and method for managing security context related to a UE. Initially, registration of a UE with a new AMF in a communication network is identified. Further, generation of new security context by new AUSF selected by the new AMF for authentication of the UE is detected. Further, presence of one or more old security contexts elated to the UE and generated by one or more old AUSFs selected by one or more old AMFs for one or more previous authentications of the UE, is detected. Upon the detection, de-registration of the UE with the one or more old AUSFs is initiated for managing security context related to the UE in the communication network. Thus, stale and inactive security context related to the UE may be deleted in the network and security of communication with the UE is enhanced.

Abstract: A method disclosed herein includes registering, by a UE, with a same PLMN over a 3GPP access and a non-3GPP access. The method includes receiving, by the UE, a notification message from a CN of the PLMN over the non-3GPP access, in response to at least one communication service pending to be delivered to the UE over the 3GPP access. The method includes sending, by the UE, a notification response message to the CN over the non-3GPP access, in response to the received notification message. In order to avoid delay in acquiring downlink communication services, the method includes triggering, by the UE, the registration procedure with the CN to receive communication services over the 3GPP access in response to the UE entering the coverage of the 3GPP access.

Methods and systems for handling encoding of radio capability information of UE using RACS. A method disclosed herein includes encoding radio capability information of a user equipment (UE) in formats of multiple radio access technologies (RATs) that have been supported by a public land mobile network (PLMN) in which the UE is registered. The method further includes assigning a radio capability identifier (RAC-ID) to the UE for signalling the radio capability information encoded in the multiple formats across the multiple RATs. The method further includes encoding the radio capability information in a specific format of the indicated RAT and assigning the RAC-ID to the UE for signalling the radio capability information and the associated encoding format.

Abstract: This disclosure provides a method for providing user equipment (UE) radio access capabilities in a handover procedure. The method includes identifying, by a source next-generation radio access network (NG-RAN), that a target public land mobile network (PLMN) does not support a UE radio access capabilities identifier (RAC ID) assigned by a source PLMN in an inter-PLMN handover procedure. Further, the method includes providing, by the source NG-RAN, to a target NG-RAN, the UE radio access capabilities instead of the UE RAC ID in response to identifying that the target PLMN does not support the UE RAC ID assigned by the source PLMN.
