    • Method and communication network node for enabling a radio base station to adjust a Radio Access Network, RAN, capability within a RAN, such as handover or scheduling, dependent on a data transport characteristics of a backhaul network, such as data transfer rate, network delay and bandwidth. The RAN and the backhaul network are parts of a telecommunication network, and the first communication network node is arranged in the telecommunication network to communicate data between the RAN and a core network node in the telecommunication network. The method comprises obtaining 300, by a RAN Adaptation Selection unit 204, 224 of the first communication network node, information related to the data transport characteristics of the backhaul network. Furthermore, the method comprises selecting 306 by the RAN Adaptation Selection unit 204, 224 that the RAN capability will be adjusted, depending on the obtained information, and when it is selected 306 the RAN capability will be adjusted, requesting 308 a RAN Adaptation unit 228 to adjust the RAN capability, the RAN Adaptation unit 228 being comprised in a Radio Base Station 220 serving the RAN. By acquiring knowledge of variations of transport characteristics in backhaul networks, RAN capabilities may be adjusted, e.g. by performing handover of UEs to other radio base stations which have better backhaul transport characteristics. Thereby, user experience for the users of the UE may be increased. In addition, an operator of the communication network may make better use of installed transport capacity.
    • 方法和通信网络节点,用于使无线电基站能够根据回程网络的数据传输特性(诸如数据传输速率,网络延迟)来调整RAN内的无线电接入网络RAN,诸如切换或调度的能力 和带宽。 RAN和回程网络是电信网络的一部分,并且第一通信网络节点被布置在电信网络中以在RAN和电信网络中的核心网络节点之间传送数据。 该方法包括由第一通信网络节点的RAN自适应选择单元204,224获取与回程网络的数据传输特性有关的信息。 此外,该方法包括由RAN自适应选择单元204,224选择306,根据获得的信息来调整RAN能力,并且当选择306时,RAN能力将被调整,请求308 RAN适配单元228 为了调整RAN能力,RAN适配单元228包括在服务于RAN的无线电基站220中。 通过获取回程网络中传输特性变化的知识,可以调整RAN能力,例如, 通过执行UE到具有更好的回程传输特性的其他无线电基站的切换。 由此,可以增加UE的用户的用户体验。 此外,通信网络的运营商可以更好地利用已安装的传输能力。

    • A method in a primary network node for handling a handover of a wireless device from a primary cell serviced by the primary network node to a neighbour cell serviced by a neighbour network node. The method comprises sending a configuration message to the wireless device, comprising instructions to evaluate in parallel a first handover event and a second handover event. The first event is based on signal quality measurements from both cells. The second event is based on signal strength measurements from both cells. To evaluate comprises determining if an entering condition for each of the events is satisfied. The method further comprises sending a handover command to the wireless device when one of: the entering condition for the first handover event is satisfied over a first time period, and the entering condition for the second handover event is satisfied over a second time period.
    • 主网络节点中的方法,用于处理无线设备从主网络节点服务的主小区到邻居网络节点服务的邻居小区的切换。 该方法包括向无线设备发送配置消息,包括并行评估第一切换事件和第二切换事件的指令。 第一个事件是基于两个信元的信号质量测量。 第二个事件是基于来自两个电池的信号强度测量。 评估包括确定是否满足每个事件的输入条件。 所述方法还包括:当在第一时间段内满足所述第一切换事件的输入条件中的一个时,向所述无线设备发送切换命令,并且在第二时间段内满足所述第二切换事件的输入条件。
