在所述小节点根据所述分流配置消息配置所述小节点与所述用户设备的 上行或下行用户面数据传输链路后， 所述小节点和所述用户设备建立上行和 / 或下行用户面连接， 这样所述小节点可以被作为中继器， 所述宏基站和所述用 户设备通过所述小节点进行上行和 /或下行用户面数据的传输。
其中，所述小节点可以是小基站 Pico ,室内基站 Femto ,低移动性基站 LoMo , 本地无线接入点 AP, 带有设备到设备 D2D ( Device to Device )功能的 UE, 低 功率节点 LPN。 其中， 需要说明的是， 上述实施例提供的数据分流的方法应用于 LTE移动 通信网络系统， 所述系统包括宏基站、 用户设备和小节点， 所述小节点的覆盖 范围处于所述宏基站的覆盖范围内， 在所述宏基站的覆盖范围内， 所述宏基站 和所述用户设备的控制面连接保持在所述宏基站和所述用户设备的直连路径。
本发明实施例提供了一种数据分流的方法、 宏基站、 用户设备和小节点， 通过用户设备发送的测量报告， 宏基站确定所述用户设备的区域范围， 基于减 小用户设备的功耗， 避免用户设备对小节点上行接收产生同频干扰的原则， 可 以根据所述用户设备的区域范围选择宏基站和用户设备之间的用户面数据传输 的链路， 并对所述用户设备和 /或小节点进行配置， 以使得所述用户设备和所述 宏基站之间根据所述选择的用户面数据传输链路进行用户面数据的传输， 从而 可以减小用户设备发送上行信号的功耗， 同样可以避免用户设备对小节点上行 接收产生同频干扰。 实施例二、 本发明实施例提供了一种数据分流的方法， 为了减小用户设备发送上行 信号的功耗，避免对宏基站内的小节点上行接收产生同频干扰，宏基站将宏基 站的不同覆盖区域的用户设备的上下行用户面数据， 分流到相应的传输链路。
