    • The present disclosure presents a method and an apparatus for self-configuring a physical cell identify (PCI) at a cell upon detecting a PCI confusion at a neighbor cell. For example, the method may include detecting that a PCI confusion exists at a second cell based on a message (e.g., configuration update message or a X2 setup response message) received from the second cell. The first cell may initiate a timer that is selected from a first timer and a second timer, the first timer longer in duration than the second timer. The first cell then configures a new PCI for the first cell when the timer expires or maintains a current PCI for the first cell when the timer is reset prior to expiration. As such, self-configuration of PCI at a cell may be achieved.
    • 本公开提供了一种在相邻小区检测到PCI混淆时,在小区处自动配置物理小区识别(PCI)的方法和装置。 例如,该方法可以包括基于从第二小区接收的消息(例如,配置更新消息或X2建立响应消息)来检测在第二小区处存在PCI混淆。 第一小区可以发起从第一定时器和第二定时器中选择的定时器,第一定时器的持续时间比第二定时器长。 然后当定时器在到期之前复位时定时器到期或维持第一个单元的当前PCI,第一个单元为第一个单元配置一个新的PCI。 因此,可以实现单元处的PCI的自配置。

    • The invention provides a method of refreshing a key in a user plane architecture 1A based dual connectivity situation. According to an embodiment of the present invention, a method, in a secondary eNB in a dual connectivity communication scenario, of refreshing a key, is provided, wherein a user equipment, a master eNB and a secondary eNB form dual connectivity, a user plane architecture 1A is applied for the dual connectivity, and the master eNB uses a master eNB key, the secondary eNB uses a secondary eNB key, the method comprises following steps: - receiving a new secondary eNB key from the master eNB; - receiving a key fresh complete from the master eNB, which indicates the user equipment has refreshed the secondary eNB key; - implementing a random access procedure with the user equipment; and- refreshing the secondary eNB key with the new secondary eNB key, and implementing data transmission with the user equipment with the new secondary eNB key.
    • 本发明提供了一种在基于用户平面架构1A的双连接情况下刷新密钥的方法。 根据本发明的一个实施例,提供了一种在双连接通信场景下的辅基站中刷新密钥的方法,其中用户设备,主基站和辅助eNB形成双连接,用户平面 体系结构1A应用于双连接,并且主基站使用主基站密钥,辅助基站使用辅助基站密钥,该方法包括以下步骤: - 从主基站接收新的辅助基站密钥; - 从主eNB接收密钥新鲜完成,其指示用户设备已经刷新了辅助eNB密钥; - 用户设备执行随机接入过程; 和 - 用新的辅助eNB密钥刷新辅助eNB密钥,并且用新的辅助eNB密钥与用户设备实现数据传输。
