摘要： 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. Embodiments herein provide a method for determining whether a base station is genuine or rouge in a wireless network. If a received authentication key matches with the authentication key generated in the UE, the method includes identifying a base station as genuine base station and carrying out a normal procedure. If the received authentication key does not match with the generated authentication key, the method includes identifying the base station as a rouge base station. The authentication key can be a digital signature (DS), a Message Authentication Code-Integrity (MAC-I), and a hash of MIB/SIBs including PCI.

摘要： Embodiments herein provide a method and system for performing a bearer type change of a plurality of radio bearers configured for a User Equipment (UE). The proposed method includes changing the bearer type of specific bearer by the network. Further, the proposed method includes checking any changes in keys or PDCP termination point or PDCP version change. Furthermore, the proposed method includes notifying the UE to change the bearer type either through reconfiguration procedure without handover or SN change procedure or reconfiguration procedure with handover or SN change procedure. The network indicates one or more operations to the UE for performing the bearer type change.

摘要： Methods and apparatuses are provided for monitoring a physical downlink control channel (PDCCH) in a wireless communication system. A UE receives a system information block (SIB) from a base station. The UE obtains a first time division duplex (TDD) uplink (UL)/downlink (DL) configuration from the SIB. The UE identifies DL subframes in a radio frame. The UE monitors the PDCCH transmitted from the base station on a DL subframe included in an on duration period of a discontinuous reception (DRX) cycle. The UE obtains information about a second TDD UL/DL configuration from the monitored PDCCH. The UE applies the second TDD UL/DL configuration to the radio frame. The DL subframe corresponds to a predetermined subframe number in the radio frame. The on duration period represents a period corresponding to a predetermined number of subframes from a subframe where the DRX cycle starts, and the on duration period is repeated periodically.

摘要： 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). A method for securing unicast message communication is provided. The method includes sending, by a user equipment (UE), a request-message for resuming radio resource control (RRC) connection to a base station, wherein the request message comprises a first-parameter defining “resume cause”. A response pertaining to at least one of network-release or network-resumption is received by the UE, wherein the response comprises a second parameter defining “resume cause”. Based on a successful-mapping between the first parameter and the second parameter, the response is acknowledged by the UE. However, for example, in case of network-rejection of the request due to network congestion, an RRC reject message comprising a first message authentication code is computed by the base station based on a stored network security context and communicated to the UE. Thereafter, a second message authentication code is mapped by the UE with the first message authentication code.

摘要： A system for converging fifth generation (5G) communication systems for supporting higher data rates beyond fourth generation (4G) systems with a technology for Internet of things (IoT) is provided. The communication method and system 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 system is provided for determining system information validity by acquiring and storing a first system information block and other system information, including information on a public land mobile network (PLMN) identity and a value tag, and determining whether the stored system information is valid for the cell. As another example, a terminal and base station are provided for performing beam failure detection and a recovery procedure using first and second configuration information for beam failure recovery (BFR) and if failure is detected, initiating a first random access (RA) procedure and if second configuration information is received while the first RA procedure is ongoing, terminating the first RA procedure and initiating a second RA procedure based on the second configuration information.
