    • A method for achieving energy-saving in a mobile communication system base station, for application in an LTE system, comprising: determining the average value of a downlink sub-frame traffic load; determining, when the average value of the downlink sub-frame traffic load is below a threshold value therefore, an MBSFN downlink sub-frame which is not carrying multicast traffic; and closing the radio frequency channel corresponding to the multicast symbol in the MBSFN downlink sub-frame which is not carrying multicast traffic. By using the method, the number of downlink sub-frames required to meet the communication traffic needs of a current cell is judged according to changes in the traffic load observed by measuring the traffic load values in that cell; sub-frames which can be closed are set as MBSFN downlink sub-frames which do not send multicast traffic; radio frequency channels occupied by the multicast symbol are closed, thereby reducing energy consumption.
    • 一种用于在LTE系统中应用的用于实现移动通信系统基站中的节能的方法,包括:确定下行链路子帧业务负载的平均值; 确定当下行链路子帧业务负载的平均值低于阈值时,确定不携带组播业务的MBSFN下行链路子帧; 并且在不携带组播业务的MBSFN下行链路子帧中关闭对应于多播符号的射频信道。 通过使用该方法,根据通过测量该小区中的业务负载值观测到的业务负载的变化来判断满足当前小区的通信业务需求所需的下行链路子帧的数量; 可以关闭的子帧被设置为不发送多播业务的MBSFN下行链路子帧; 组播符号占用的射频信道关闭,从而降低能耗。

    • Data segmenting apparatus and method are provided. An apparatus for segmenting an input data sequence includes: a boundary searching device configured to search for one or more candidate boundaries in the data sequence, to obtain one or more candidate segmenting schemes formed by different combinations of these candidate boundaries; and an evaluating device configured to generate, for each candidate segmenting scheme, an evaluation value of each candidate boundary in the scheme by evaluating a segmenting loss caused by using the candidate boundary to segment the data sequence, and determine whether the candidate boundary is valid in the candidate segmenting scheme according to the evaluation value reflecting association relationship between a pair of adjacent data segments adjoining to the candidate boundary and association relationship between each of one or more pairs of non-adjacent data segments, each of which includes two non-adjacent data segments located at two sides of the candidate boundary.
    • 提供数据分割装置和方法。 一种用于分割输入数据序列的装置包括:边界搜索装置,被配置为搜索数据序列中的一个或多个候选边界,以获得由这些候选边界的不同组合形成的一个或多个候选分割方案; 以及评估装置,被配置为针对每个候选分割方案,通过评估由所述候选边界引起的分段损失来分割所述数据序列,并且确定所述候选边界是否有效,从而生成所述方案中的每个候选边界的评估值 所述候选分割方案根据所述评估值反映出与所述候选边界相邻的一对相邻数据段之间的关联关系以及一对或多对非相邻数据段中的每一对之间的关​​联关系,每个所述非相邻数据段包括两个不相邻数据 位于候选边界两侧的段。

    • A path configuration message is sent to nodes in a multi-hop network along a path between a source node and destination nodes. The path configuration message includes path information and one or more special channel access parameters associated with the path information. The path configuration message temporarily changes the channel access priority for packets matching the path information in the special message. The nodes along the path therefore have higher channel access priority relative to other nearby nodes and other traffic flows. At the end of the a length of a time determined by a time to live parameter in the special message, the nodes resume using default channel access parameters in place of the special channel access parameters for packets matching the path information.
    • 路径配置消息沿着源节点和目的节点之间的路径发送到多跳网络中的节点。 路径配置消息包括与路径信息相关联的路径信息和一个或多个特殊信道访问参数。 路径配置消息临时更改与特殊消息中的路径信息匹配的数据包的通道访问优先级。 因此,沿着路径的节点相对于其他附近的节点和其他业务流具有较高的信道接入优先级。 在由特殊消息中的生存时间参数确定的时间长度结束时,节点恢复使用默认信道接入参数,代替与路径信息匹配的分组的特殊信道接入参数。
