    • User equipment (UE), an enhanced NodeB (eNB) and method of reducing handover latency are generally described. The UE may transmit measurement feedback to the eNB based on control signals. The UE may receive a reconfiguration message from the eNB or another eNB to the UE is attached. The reconfiguration message may contain reconfiguration information indicating whether or not a physical layer or layer 2 of the UE is to be reconfigured and/or a security key is to be updated. The reconfiguration information may be dependent on whether the handover is between eNBs controlled by a same entity and/or whether the handover comprises an intra-frequency transition. The UE or eNB may initiate handover of the UE. During handover the UE may avoid physical layer or layer 2 reconfiguration or the security key update. The security key and data for the UE may be provided directly between the eNBs.
    • 通常描述用户设备(UE),增强型节点B(eNB)以及减少切换等待时间的方法。 UE可以基于控制信号向eNB发送测量反馈。 UE可以从eNB接收重新配置消息,或者附加到UE的另一个eNB。 重新配置消息可以包含指示UE重新配置物理层或第二层是否被重配置的重新配置信息和/或要更新安全密钥。 重新配置信息可以取决于切换是否在由相同实体控制的eNB之间和/或切换是否包括频率内转换。 UE或eNB可以发起UE的切换。 在切换期间,UE可以避免物理层或层2重新配置或安全密钥更新。 UE的安全密钥和数据可以直接在eNB之间提供。

    • A communications system provides a robust and fast inter-base station handoff mechanism, e.g. for networks using Enhanced Base Stations (EBS) equipment. A method for connecting a mobile device to a destination base station in the wireless communications system, may include steps of receiving a mobile device measurement report, transferring context information from a serving base station to possible target base stations, and receiving admission control information from possible target base stations. A priority list of the possible target base stations is calculated and sent to the mobile device. The mobile device connects to one or more of possible target base stations according to the priority list. The method may also entail receiving a release message from one of the possible target base stations to which the mobile device has successfully established a wireless connection, to allow release of resources of the prior serving base station.
    • 通信系统提供鲁棒且快速的基站间切换机制,例如。 对于使用增强型基站(EBS)设备的网络。 一种用于在无线通信系统中将移动设备连接到目的地基站的方法可以包括以下步骤:接收移动设备测量报告,将上下文信息从服务基站传送到可能的目标基站,以及从可能的接收接收准入控制信息 目标基站。 计算可能的目标基站的优先级列表并将其发送到移动设备。 移动设备根据优先级列表连接到一个或多个可能的目标基站。 该方法还可能需要从移动设备已成功建立无线连接的可能目标基站之一接收释放消息,以允许释放先前服务基站的资源。
