Abstract: Systems and methods of a security framework for an RRC connection are described. The UE receives a release message that comprises a current Next Hop Chaining Counter (NCC). The UE derives a new KeNB* using the current NCC and transmits an EDT RA preamble to same or a different base station. After receiving an RAR with an uplink allocation, the UE transmits a RRCConnectionResumeRequest message. The UE transmits uplink data encrypted using KeNB* if the uplink allocation includes a data allocation sufficient for the data, fall backs to a legacy RRC connection procedure in which the stored KeNB* is discarded and then KeNB* is re-derived if the data allocation is insufficient for the data due to a CE level change, and fall backs to a legacy RRC connection procedure in which the stored KeNB* is used instead of discarding KeNB* if the uplink allocation excludes the data allocation.

Abstract: Example transmission rate control methods and apparatus are described. One example method includes obtaining a user equipment aggregate maximum bit rate (UE-AMBR) by a master base station. The master base station determines, based on the UE-AMBR, a first UE-AMBR used for the master base station and a second UE-AMBR used for a secondary base station. The master base station sends the second UE-AMBR to the secondary base station, and sends instruction information used to instruct the secondary base station to control data splitting for the master base station to the secondary base station. In this application, a transmission rate between each base station and a UE is controlled by allocating a UE-AMBR.

Abstract: A UE may decode a radio-resource control (RRC) reconfiguration message comprising a conditional handover (CHO) configuration (CHO-Config) which may identify a CHO configuration for at least one target candidate cell. The CHO configuration may include two or more CHO triggering events for an entry condition. The UE may monitor measurement quantities of the target candidate cell for the entry condition to determine if any of the CHO triggering events are met, start a first count-down timer when the entry condition of a first of the CHO triggering events is met and start a second count-down timer when the entry condition of a second of the CHO triggering events is met. The UE may apply the CHO configuration to the target candidate cell when both of the two CHO triggering events remain fulfilled upon expiration of the both timers.

A first security parameter indication is introduced into uplink data on a first bearer, and a base station can determine, based on the first security parameter indication in the uplink data, whether first security processing of the uplink data is performed using a first security parameter or a second security parameter, so as to select a corresponding security parameter to perform second security processing; and a second security parameter indication is introduced into downlink data, and UE can determine, based on the second security parameter indication in the downlink data, whether the first security processing of the data is performed using the first security parameter or the second security parameter, so as to select a corresponding security parameter to perform the second security processing.

Abstract: A method of user data authorization based on blockchain includes: storing, by a first application client, encrypted user data of user data in a blockchain database through a blockchain node, generating authorization information in response to a request of acquiring the user data by a second application client, and notifying the second application client to obtain the authorization information such that the second application client obtains the user data based on the encrypted user data and the authorization information. The encrypted user data is stored in the blockchain database such that the encrypted user data cannot be tampered with and a leak of real user data is prevented. The second application client obtains the user data based on the authorization information and the encrypted user data.

Abstract: Embodiments of a User Equipment (UE), Evolved Node-B (eNB) and methods of communication are generally described herein. The UE may receive a SystemInformationBlockType1 from an eNB. The UE may determine that the eNB supports Fifth Generation Core (5GC) operation if the SysteminformationBlocklType1 message includes a plmn-Identity-5GC-r15 parameter. The UE may transmit a radio resource control (RRC) connection request message to establish an RRC connection. If it is determined that the eNB supports 5GC operation, and if the UE supports 5GC operation, the UE may encode the RRC connection request message in accordance with a default new radio packet data convergence protocol (NR PDCP) configuration; and may use NR PDCP for one or more subsequent messages.

Abstract: A handle assembly and a surgical stapler including the handle assembly is provided, wherein the handle assembly includes a first handle and a second handle. A first limit portion and a second limit portion are provided on one end of the first handle and one end of the second handle, respectively. The first limit portion is on a proximal end side of the second limit portion. As the first handle is at its initial position, the first limit portion abuts the second limit portion to prevent the first handle from rotation in a second direction. In an invalid state, the first handle can still be squeezed; meanwhile, the first and the second limit portions limit the initial angular position of the first handle and the initial position of the second handle. When the first handle is not rotated, the second handle cannot be rotated and the stapler cannot be fired.
