具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
相关技术中，用户设备向基站上报测量报告。基站基于测量报告判断用户设备是否需要进行小区切换。但是，测量结果受环境影响可能不准确，导致发起小区切换的时机和确定的目标基站可能不合适，切换到目标小区后的通信服务质量较差，或者出现在两个小区之间频繁切换(或称乒乓切换)的情况。这样，影响通信服务质量，浪费较多的网络资源，以及消耗较多的设备功耗。
为解决上述问题，本实施例中用户设备根据移动轨迹估计出目标小区，并将该目标小区上报给源基站。源基站参考用户设备的目标小区，以便确定更准确的目标小区来进行切换。提高小区切换的成功率，以及减少乒乓切换。
图1是根据一示例性实施例示出的一种小区切换的处理方法的流程图，该小区切换的处理方法用于用户设备中，其中，用户设备可以是移动电话，计算机，数字广播终端，消息收发设备，游戏控制台，平板设备，医疗设备，健身设备，个人数字助理等。如图1所示，该方法包括以下步骤101-104。
在步骤101中，获取当前的移动轨迹。
在步骤102中，将当前的移动轨迹与历史的移动轨迹进行匹配，获取匹配度。
在步骤103中，根据匹配度高于预设的匹配阈值的历史的移动轨迹，以及根据历史的移动轨迹与小区的对应关系，确定目标小区。
在步骤104中，向源基站发送切换请求，所述切换请求包括确定的所述目标小区的目标小区标识。
如果没有匹配度高于预设的匹配阈值的历史的移动轨迹，则结束本次流程，不需要确定目标小区，可以上报测量报告等。
本实施例中，用户设备在发生移动时，开始获取当前的移动轨迹。或者，在移动速度大于预设的速度阈值(如时速20、40千米等)时，开始获取当前的移动轨迹。用户设备基本静止，或者移动速度不大于速度阈值，则不需要获取当前的移动轨迹，也就可以不采用本实施例的方案，因为基本不太可能发生小区切换。在静止时，可以采用相关技术中的上报测量报 告的实现方案。
当前的移动轨迹可以是从发生移动到当前时刻的移动轨迹，也可以是最近一段时长(如1小时内)的移动轨迹，也可以是最近一段距离(如20千米)的移动轨迹。
用户设备预先存有历史的移动轨迹，该历史的移动轨迹是该用户设备曾经发生的移动轨迹。也可以包括其它用户设备曾经发生的移动轨迹，通过网络侧获取。步骤101中当前的移动轨迹在将来也可以作为历史的移动轨迹。历史的移动轨迹可以由多个移动轨迹组成。
当前的移动轨迹和历史的移动轨迹长短不一，所以获取的匹配度可以是：当前的移动轨迹与历史的移动轨迹重合的部分，与当前的移动轨迹和历史的移动轨迹中较短的移动轨迹的比值。匹配阈值可以根据实际需要而配置，匹配阈值越高，确定的目标小区越准确，如匹配阈值为60％、80％和90％等。步骤102中可以采用模糊匹配、近似匹配、聚合等算法，来确定重合部分。
用户设备预先存有历史的移动轨迹与小区的对应关系，该对应关系中的小区可以是用户设备在历史的移动轨迹上接入过的小区，也可以是网络侧配置的小区，网络侧可以根据移动轨迹规划较合适的小区。
根据匹配得到的历史的移动轨迹，可以预测未来的移动轨迹，覆盖未来的移动轨迹的小区，很可能是即将覆盖用户设备的小区，将该小区作为目标小区，可以较好的为用户设备提供通信服务。
用户设备在确定目标小区后，可以向源基站发送切换请求，该切换请求可以是一种RRC(无线资源控制)消息。可以通过特定的标志位或标志位的特定取值来标识切换请求。通过切换请求携带目标小区的目标小区标识。
本实施例中，在刚开始发生移动时，移动轨迹较短，可能与多个历史的移动轨迹有较高的匹配度，但是此时匹配到的历史的移动轨迹数量较多，确定的目标小区也可能较多。此时可以将确定的所有目标小区均上报给源基站。或者，在目标小区较多的情况暂时不上报。
随着用户设备的持续移动，当前的移动轨迹越来越长，有较高匹配度的历史的移动轨迹逐渐变少，匹配的准确度也越来越高，确定的目标小区也越来越少，此时上报的目标小区更准确。
本实施例提供了用户设备根据移动轨迹确定和上报目标小区的实现方案。用户设备可以根据自身的移动轨迹来确定目标小区，该目标小区可以对未来用户设备可能的移动轨迹有较好的覆盖。有助于提高小区切换的成功率，保证切换后的通信服务质量，减少乒乓切换的发生。
在一个实施例中，所述方法还包括：步骤A1-步骤A2。
在步骤A1中，获取当前时间。
在步骤A2中，确定与所述当前时间关联的历史时间。
所述步骤102包括：步骤A3。
在步骤A3中，将当前的移动轨迹与所述历史时间对应的历史的移动轨迹进行匹配。
本实施例中当前时间可以包括小时和分钟，如8:00；当前时间也可以包括年、月、日等。本实施例可以只关注小时和分钟。与所述当前时间关联的历史时间可以是包含与当前时间相同的小时和分钟的历史时间，历史上包含该小时和分钟的多天。该多天可以是预设时长范围内的多天，如最近一个月内每天的8:00，或者最近1年内每天的8:00。本实施例适用于移动轨迹按天循环的情况，例如用户每天上下班的移动轨迹便具有按天循环的特点，当前时间为用户当前上班路上的时间，关联的历史时间为用户过去1个月内上班路上的时间。
或者，当前时间可以包括星期、小时和分钟，如星期一的8:00。关联的历史时间可以是过去1个月内每个星期一的8:00，或者是过去1年内每个星期一的8:00。本实施例适用于移动轨迹按周循环的情况，例如用户每周固定去一次某个特定的地方。
本实施例还可以适用于按月或年循环的情况，此处不再赘述。
当前时间可以是当前的移动轨迹所对应的时间段。历史时间可以是历史的移动轨迹所对应的时间段。当前时间与历史时间存在重合的时间段时，该历史时间即为与所述当前时间关联的历史时间。
