  • Publication number: 20220353749
    Abstract: This document describes methods and devices for a handover of a user equipment from source base station (a Fifth Generation (5G) New Radio (NR) base station) to a target base station (another 5G NR base station or an Evolved Packet Core (EPC) network base station). The source base station, which is in communication with the user equipment, determines to handover the user equipment to the target base station. The source base station, then determines whether to use a delta configuration or a full configuration for handing over the user equipment. For the full configuration, the source base station either excludes the delta configuration from, or indicates use of the full configuration in, handover preparation information. By so doing, the source base station enables handover of the user equipment to the target base station.

  • Publication number: 20220345883
    Abstract: A base station security communicates with a UE operating as an SN in dual connectivity of the UE with a first MN and the SN. The base station communicates with the UE over a radio interface using a first security key (802). The base station then receives, from a second MN, a first message including data for obtaining a second security key for communicating with the UE (804) and suspends application of the second security key to downlink traffic to the UE until a second message is received (806). In response to receiving the second message, base station communicates with the UE over the radio interface using the second security key (808).
