Abstract: A system and method provide a security aspect for a UE in dual connectivity mode of operation in wireless communication networks. The system and method provide secure simultaneous transmission and reception in a secure manner between a User Equipment (UE) and one or more eNodeBs (eNBs) configured in an inter-eNB carrier aggregation scenario. The system establishes of a security context between the UE and the Secondary eNB (SeNB) using the RRC signaling between the UE and the Master eNB (MeNB), when a plurality of SCells within SeNB are added simultaneously. The system also detects the intruder in the user data radio bearers, while a UE is operating in dual connectivity mode of operation.

Abstract: A method and system that enhances the existing access barring mechanism as specified in the current 3GPP specification is disclosed. The method disclosed provides enhancing the access barring mechanism to accommodate application level barring between the User equipment (UE) and the network. The method disclosed individually restricts or permits access of network to every requesting application on the UE, based on granular category of the application and priority levels of the application within the granular category. The method disclosed also specifies handling of back-off timers; reject cause values and Access Point Name (APN) configuration by Access Stratum (AS) and Non Access Stratum (NAS) layer to support application level barring of UEs using the enhanced access barring mechanism. The enhanced access barring mechanism enables providing service to applications independent of other barred applications or priorities. The method disclosed provides a mechanism for access control for connected mode UEs.

Abstract: Accordingly, the embodiments herein provide a method for authentication of an IAB node by an IAB-donor node in a wireless network. The method includes obtaining an IAB authorization information of the IAB node from one of an Access and Mobility Management Function (AMF) and a Mobility Management Entity (MME) of the wireless network, determining whether the IAB authorization information of the IAB node indicates the IAB node is authorized, and allocating a unique identity/parameter to the IAB node during an IAB-Mobile Termination (MT) setup and/or Backhaul Radio Link Control (RLC) channel establishment and/or Routing update phase. Further, the method includes storing the unique identity/parameter in a user equipment (UE)-context, which is used to identify the UE-context during an IAB-Distributed Unit (DU) part setup for authorization check and/or authentication.

Abstract: The present disclosure relates to a pre-5G or 5G communication system to support higher data rates beyond 4G communication system such as LTE. The present disclosure enables the 3GPP system to protect the broadcasted unique UAV identities for a secured UAV communication. In remote identification process, the UAVs send the messages with flight information to the receiving party (i.e., UTM/USS, a TPAE or another UAV). Also, there are use cases on local broadcast of UAV identities for remote identification and tracking purposes. The present disclosure renders a mechanism that only the authorized personnel is able to decode the received broadcasting ID from the initiating UAV. The present disclosure protects unique UAV identities broadcasted so that, the fake UAV or unauthorized personnel cannot use the broadcasted ID for certain attacks such as impersonation of genuine UAV, tracking of the UAV and so on.

Abstract: A method and system for providing selective protection of data exchanged between user equipment (UE) and network is disclosed. The selective protection is applied to a packet, a bearer or an access point name for secure exchange of data between the UE and the network. The network decides to apply selective protection based on configuration of network, configuration of UE, load in the network, battery power availability of UE, type of application running on UE. Further, the UE can request for selective protection based on the type of application running on UE and the battery level availability of the UE. The selective protection is either enabled or disabled dynamically by the network. Further, various mechanisms for applying selective protection for each bearer, each packet and each Access Point Name (APN) are disclosed. Additionally, the method for identifying a secured and a non secured bearer has also been disclosed.
