摘要
研究了5G NTN在连接模式下的移动性策略,包括基于位置触发的切换(D1事件)、基于时间触发的切换(T1事件)、UE上报粗略位置信息、D1事件和T1事件的选择、目标小区的选择、大量UE几乎同时切换引起的信令风暴。最后分析了NTN-TN间的移动性策略,对于NTN向TN的切换,建议采取基于信号强度和位置联合触发的切换策略;对于TN向NTN的切换,建议采取基于信号强度触发的切换策略。
It studies the 5G NTN mobility strategies in connected mode,including on location triggering(D1 event)based hand-over and time triggering(T1 event)based hand-over,UE coarse location report,how to select D1 event and T1 event,how to select the target cell,signaling storm caused by a large number of UE handover almost at the same time.Finally,it analyzes mobility strategies between NTN and TN in connected mode,suggests that hand-over based singnal strength and location triggering is used for NTN to TN,and hand-over based singnal strength triggering is used for TN to NTN.
