在这种组网类型中，首先，网络要保障对UE的持续服务，尽管UE处于移动状态，业务不中断，那就要依靠小区间的切换，需要为UE配置触发切换的测量事件。但是由于UE的移动会造成大量测量结果的上报，尤其是高速移动的UE可能穿梭于小区之间，触发测量报告的几率要大得多，甚至造成频繁切换。所以，既要保障UE正常通信，还要避免大量测量报告的上报以及频繁切换。
其次，在重叠覆盖的范围内，为了合理利用两个小区的资源，需要协调两个小区服务的用户数量。也就是需要网络参与控制，实现两个小区间的负载均衡。同样这也需要测量结果的辅助。
为了实现切换和负载均衡，都需要借助测量结果的上报。目前LTE协议中存在多种测量事件，其中，测量事件A3为邻区信号强度高于本区信号强度一定门限。测量事件A5为本区信号强度低于一定门限，且邻区信号强度高于一定门限。
针对相关技术中，对于不同移动速度的终端采用同样的测量事件而导致的上报大量的测量报告问题，尚未提出有效的解决方案。

具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
本发明的其它特征和优点将在随后的说明书中阐述，并且，部分地从说明书中变得显而易见，或者通过实施本发明而了解。本发明的目的和其他优点可通过在所写的说明书、权利要求书、以及附图中所特别指出的结构来实现和获得。
为了使本技术领域的人员更好地理解本发明方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分的实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
在异频组网类型中，由于两个频点的覆盖和UE移动的复杂性，使得切换类型也很多样，那么简单的配置测量事件A3和A5已经不能满足组网的需求。
在本实施例中提供了一种终端测量事件的配置方法，图3是根据本发明实施例的终端测量事件的配置方法的流程图，如图3所示，该流程包括如下步骤：
步骤S302，获取终端的当前移动状态，其中，上述当前移动状态用于指示上述终端的当前移动速度；
步骤S304，根据上述当前移动状态为上述终端配置与上述当前移动状态对应的测量事件。
通过上述各个步骤，采用根据终端的移动速度配置与移动速度对应的测量事件的技术手段，解决了相关技术中对于不同移动速度的终端采用同样的测量事件而导致的上报大量的测量报告问题，针对不同的UE配置不同的测量配置，减少不必要的切换和测量上报，实现了结合UE的移动状态，针对不同的UE配置不同的测量配置，做出不同的判决的方案。
可选地，步骤S304可以存在多种实现方式，在本发明实施例的一个可选示例中，可以通过以下技术方案实现：比较上述当前移动状态所指示的移动速度与预设阈值；根据比较结果为上述终端配置测量事件，也就是说，可以根据判断移动速度是否大于预设阈值，并根据不同的比较结果对上述终端进行配置测量事件。
需要说明的是，在本发明实施例以及优选实施例中，确定“终端当前的移动状态”可以有多种体现方式，例如：可以是本发明实施例中提及的移动速度，也可以是终端在一定时间内的在不同小区间的切换次数，本发明实施例对此不作限定，因此，本领域的技术人员从本发明实施例提供的技术方案中能够获知的确定终端当前移动状态的技术方案均在本发明实施例的保护范围内。
在本发明实施例中，根据移动速度是否大于预设阈值的情况来配置测量事件存在以下两种情况：当上述当前移动速度大于上述预设阈值时(可以理解为终端以一种较高的移动速度在移动)，为上述终端配置测量对象为第一小区的测量事件A3和/或测量对象为第二小区的测量事件A5，其中，上述第一小区采用第一频点，上述第二小区采用第二频点，上述测量事件A5中的本小区的信号强度低于第一门限，邻居小区的信号强度高于第二门限，且上述第一门限小于上述第二门限。
当上述当前移动速度小于或者等于上述预设阈值时(可以理解为终端以一种较低的移动速度在移动)，为上述终端配置测量对象为上述第一小区和上述第二小区的测量事件A3，以及测量对象为上述第一小区和上述第二小区的测量事件A5，其中，上述测量事件A5中的本小区的信号强度低于第一门限，邻居小区的信号强度高于第二门限，且上述第一门限大于上述第二门限。
在实际应用中，在为终端配置完测量事件后，在满足测量事件的上报条件时，终端向网络侧上报测量报告，网络侧在收到测量报告后：根据以下至少之一判断上述终端是否进行小区切换：上述当前移动速度、上述第一小区和上述第二小区的负荷状况、上述测量事件的类型，其中，上述小区切换包括以下至少之一：从上述第一小区到第三小区的切换、从上述第一小区到上述第二小区的切换，上述第三小区采用上述第一频点，需要说明的是，在本发明实施例中的上述终端隶属于上述第一小区，当然，在终端隶属于第二小区或者第三小区时，采取的技术方案是类似的，本发明实施例对此不作限定。
具体地，由于终端移动速度所处的状态不同，当移动速度大于预设阈值，即终端处于高速移动的状态时，通过以下方式判断上述终端是否进行小区切换：如果上述终端从第一小区移动至第三小区，且获取的上述测量事件的类型为对于测量对象为上述第一小区的A3事件，则判断上述终端从第一小区切换至第三小区；或者如果上述终端从第一小区移动至上述第二小区与上述第一小区的交叉覆盖区域，且获取的上述测量事件的类型为对于测量对象为上述第二小区的A5事件，则判断上述终端从上述第一小区切换至上述第二小区，其中，上述交叉覆盖区域为上述第一小区和上述第二小区的部分重叠区域；当上述当前移动速度大于上述预设阈值时，如果上述终端在上述第一小区中移动至上述第二小区与上述第一小区的重叠覆盖区域，且获取的上述测量事件的类型为对于测量对象为上述第二小区的A5事件，则判断上述终端不进行从上述第一小区到上述第二小区的切换，其中，上述第一小区的覆盖范围大于上述第二小区的覆盖范围，且上述重叠覆盖区域为上述第一小区完全覆盖上述第二小区的区域。
即当UE为中高速移动状态时，为防止频繁的切换，应该避免终端UE在重叠区域的切换。因此只保障覆盖区域的切换，且尽量将中高速UE接入广覆盖的小区，并不作为负载均衡的对象。例如，F1小区(相当于上述实施例的第一小区)和F2小区(相当于上述实施例的第二小区)重叠交叉覆盖，且F1频点覆盖广。如果UE隶属F1小区，当UE从一个F1小区移动到另一个F1小区(相当于上述实施例的第三小区)的覆盖范围，需要进行切换，则网络侧需要为其配置测量对象为F1的A3测量事件；当UE从一个F1小区移动到一个F2小区的交叉覆盖区域，需要进行切换，则网络侧 需要为其测量对象为F2的A5测量事件。当UE从一个F1小区移动到一个F2小区的重叠覆盖区域，不切换。或者，如果UE隶属F2小区，当UE从一个F2小区移动到一个F1小区的覆盖区域，需要进行切换，则网络侧需要为其配置测量对象为F1的A3测量事件；当UE从一个F2小区移动到一个F2小区，不切换，等待UE切换至F1小区。其中，这里用到的测量事件A5的本区信号强度低于门限th1，邻区信号强度高于门限th2，且th1小于th2，也就是邻区信号要好于本区信号。这样的配置方案既能保证F1小区间的正常切换以及F2小区补盲地区的正常切换，增强了高速用户的鲁棒性，还减少了测量报告的上报次数。
当移动速度小于或者预设阈值，即终端处于低速移动的状态时，通过以下方式判断上述终端是否进行小区切换：如果上述终端从第一小区移动至第二小区或第三小区，且获取的上述测量事件的类型为对于测量对象为上述第一小区的A3事件，则判断上述终端从第一小区切换至第二小区或第三小区；或者如果上述终端从第一小区移动至第二小区或第三小区，且获取的上述测量事件的类型为对于测量对象为上述第一小区和/或第二小区的A5事件，则根据上述第一小区、上述第二小区和上述第三小区的负荷状况判断是否进行上述小区切换。
即在终端处于低速运行的状态时，还要根据负荷状况这个因素来判断是否进行小区之间的切换，具体方案如下：当上述第一小区的负荷与上述第二小区的负荷的差值大于第一预定门限时，则进行上述第一小区至上述第二小区的切换；当上述第一小区的负荷与上述第三小区的负荷的差值大于第二预定门限时，则进行上述第一小区至上述第三小区的切换，上述第一预定门限和上述第一预定门限的值可以相同也可以不同，本发明实施例对此不做限定。
即当UE处于低速移动状态时，网络侧既要保障其进行正常切换，又可以将其作为负载均衡的对象。例如，F1小区和F2小区重叠交叉覆盖，且F1覆盖广。如果UE隶属F1小区，当UE从一个F1小区移动到另一个F1小区的交叉覆盖范围，需要进行切换，则网络侧需要为其配置测量对象为F1的A3测量事件；当UE从一个F1小区移动到另一个F1小区的重叠覆盖范围，可进行负载均衡，则网络侧需要为其配置测量对象为F1的A5测量事件；当UE从一个F1小区移动到一个F2小区的交叉覆盖区域，则需要进行切换，则网络侧为其测量对象为F2的A3测量事件。当UE从一个F1小区移动到一个F2小区的重叠覆盖边缘，可进行负载均衡，则网络侧需要为其配置测量对象为F2的A5测量事件。当UE从一个F1小区到一个F2小区的重叠覆盖中心，需要进行切换，则网络侧需要为其配置测量对象为F2的A3测量事件。或者，如果UE隶属F2小区，当UE从一个F2小区移动到一个F1小区的交叉覆盖区域，需要进行切 换，则网络侧需要为其配置测量对象为F1的A3测量事件；当UE从一个F2小区移动到一个F1小区的重叠覆盖区域，可进行负载均衡，则网络侧需要为其配置测量对象为F1的A5测量事件；当UE从一个F2小区移动到另一个F2小区的交叉覆盖范围，需要进行切换，则网络侧需要为其配置测量对象为F2的A3测量事件；当UE从一个F2小区移动到另一个F2小区的重叠覆盖范围，可进行负载均衡，则网络侧需要为其配置测量对象为F2的A3测量事件。其中，这里用到的测量事件A5的本区信号强度低于门限th3，邻区信号强度高于门限th4，且th3大于th4。也就是本区信号要好于邻区信号。这样的配置既保障了网络对UE的服务质量，还优化了网络性能。
可选地，可以通过无线资源利用率来表征上述负荷状况。
综上所述，本发明实施例提出的是一种结合UE的移动状态，针对不同移动状态的UE配置不同的测量配置，并根据UE的不同测量报告和系统测量做出不同的切换判决方案。
为了更好的理解上述技术方案，根据终端的移动速度对终端配置测量事件还可以通过如下过程实现，如图4所示：
步骤S402：判断UE是否为中高速移动状态，如是，转入步骤S404；否则，转入步骤S406；
步骤S404：如果UE为中高速移动状态，为其配置测量对象为F1的测量事件A3和测量对象为F2的测量事件A5，且测量事件A5中的th1(门限)小于th2(门限)。
步骤S406：如果UE为低速移动状态，为其配置测量对象为F1和F2的测量事件A3和测量事件A5，且测量事件A5中th3大于th4。
终端中的切换判决模块负责对接收到的测量报告进行处理，结合UE和测量对象的状况，判断该UE是否达到切换条件。如是，触发切换。或者，判断该UE是否符合负载均衡的条件，如是，进行负载均衡。
一旦网络侧接收到UE的测量结果，切换判决模块根据接收到的测量报告进行切换处理的过程可以通过以下过程实现，如图5所示：
步骤S502：判断UE是否为中高速移动状态，如是，转入步骤S504；否则，转入步骤S506；
步骤S504：如果接收到的是测量对象为F1或测量对象为F2的A3测量事件，则判定切换，转入步骤S514；否则，转入步骤S512；
步骤S506：如果UE为低速移动状态，再判断测量事件是否为测量对象为F1或F2的测量事件A3，如是，判定切换，转入步骤S514；否则，转入步骤S508；
步骤S508：判断测量对象为F1或F2的测量事件是A5，如是，转入步骤S510；否则，转入步骤S512；
步骤S510：再判断目标小区比本小区的负荷的差值是否大于一定的门限，如是，转入步骤S514；否则，两个小区负荷相近，则转入步骤S512；
步骤S512：不进行切换；
步骤S514：判定进行小区切换。
综上所述，本发明优选实施例的技术方案，对中高速UE只保障切换，配置A3事件和A5事件，对低速UE既保障切换又作负载均衡，配置A3事件和A5事件。一旦网络侧收到UE的测量报告，会根据测量事件、UE的移动状态、目标小区的负荷等条件，做出切换判决。
在本实施例中还提供了一种终端测量事件的配置装置，用于实现上述实施例及优选实施方式，已经进行过说明的不再赘述，下面对该装置中涉及到的模块进行说明。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。图6为根据本发明实施例的终端测量事件的配置装置的结构框图。如图6所示，该装置包括：
获取模块60，设置为获取终端的当前移动状态，其中，上述当前移动状态用于指示上述终端的当前移动速度；
配置模块62，与获取模块60连接，设置为根据上述当前移动状态为上述终端配置与上述当前移动状态对应的测量事件。
通过上述各个模块的综合作用，采用根据终端的移动速度配置与移动速度对应的测量事件的技术手段，解决了相关技术中对于不同移动速度的终端采用同样的测量事件而导致的上报大量的测量报告问题，针对不同的UE配置不同的测量配置，减少不 必要的切换和测量上报，实现了结合UE的移动状态，针对不同的UE配置不同的测量配置，做出不同的判决的方案。
可选地，配置模块62为了完成上述记载的功能，如图7所示，配置模块62可以包括以下单元：比较单元620，设置为比较上述当前移动状态所指示的移动速度与预设阈值；配置单元622，与比较单元620连接，设置为根据比较结果为上述终端配置测量事件。
在本发明实施例提供的终端测量事件的配置装置中，在配置单元622完成了为终端配置测量事件的技术方案，还可以根据测量事件的类型、终端的移动速度以及负荷状况判断上述终端的小区切换情况。
在具体实施例过程中，为了更好的实现上述终端测量事件的配置方法及装置所公开的技术方案，本发明优选实施例还提供了以下技术方案：
在异构网络中，在宏站的覆盖范围内，或者在宏站的覆盖盲区部署低功率的微站。假设宏站Macro使用的频点为F1，低功率微站使用的频点为F2(如图1和图2所示的组网场景)。
本发明优选实施例的技术方案主要包含两个模块：测量配置模块和切换判决模块。
测量配置模块的具体实现为：网络侧根据UE的移动状态，为不同移动状态的UE配置不同的测量事件。
如果UE为中高速移动状态的UE，为其配置测量对象为F1(可以理解为上述实施例中采用第一频点的第一小区)的测量事件A3和测量对象为F2(可以理解为上述实施例中采用第二频点的第二小区)的测量事件A5，其中，测量事件A5的上报条件为：本区信号强度低于一定的门限，邻区信号强度高于一定的门限。对于中高速移动状态的UE，其配置A5事件上报的条件为：本区信号强度低于一定的门限th1，邻区信号强度高于一定的门限th2。且th1小于th2。中高速移动的UE根据网络侧的测量配置对本小区和相邻小区进行测量，当满足测量上报条件后，UE将向网络侧上报相应的测量报告。
如果UE为低速移动状态的UE，为其配置测量对象为F1和F2的测量事件A3以及测量对象为F1和F2的测量事件A5,其中，测量事件A5的上报条件为：本区信号强度低于一定的门限，邻区信号强度高于一定的门限。对于低速移动状态的UE，其配置A5事件上报的条件为：本区信号强度低于一定的门限th3，邻区信号强度高于一定 的门限th4。且th3大于th4。低速移动的UE根据网络侧的测量配置对本小区和相邻小区进行测量，当满足测量上报条件后，UE将向网络侧上报相应的测量报告。
切换判决模块的具体实现为：当网络侧接收到UE上报的测量报告后，网络侧根据UE的移动状态、小区的负载状况和上报的测量事件的类型等，做出切换判决。
如果UE为中高速移动状态的UE，当网络侧接收到的测量事件是测量对象为F1的测量事件A3，那么网络侧判断该UE移动到相邻的宏小区覆盖范围内，网络侧将判定UE需要切换到相邻的宏小区；如果网络侧接收到的测量事件为F2的测量事件A5，那么网络侧判断该UE移动到用于补盲的相邻微小区覆盖范围内，网络侧将判定UE需要切换到相邻的微小区；
如果UE为低速移动状态的UE，且测量事件是配置测量对象为F1或F2的测量事件A3，那么网络侧判断该UE移动到相邻的宏小区或微小区覆盖范围内，网络侧将判定UE需要切换到相邻的宏小区或微小区；如果网络侧接收到的测量事件为为F1或F2的测量事件A5，系统侧需要再根据本小区和目标小区的负荷状况进行切换判决，具体为：如果目标小区比本小区的负荷的差值大于一定的门限，说明目标小区比本小区负荷轻很多，那么网络侧可以判定该UE切换到相邻小区，否则网络侧将不会判定该UE进行切换，即UE继续留在源小区进行服务。本小区和目标小区的负荷状态可以使用小区的无线资源利用率来表示，但不限于此。
本发明优选实施例实际上提供一种为针对不同的UE配置不同的测量配置，并作出不同的判决的方案。该方案分为两个部分：测量配置模块和切换判决模块。
测量配置模块负责为每个UE配置测量配置。在重叠交叉覆盖的组网结构中，需要配置两类测量事件：一种用于触发切换的测量事件，一种用于辅助负载均衡算法选择用户的测量事件。其中，可利用的测量事件A3和A5。
需要说明的是，优选实施一和优选实施例二中的附图8和附图9中：实线为低速移动UE，虚线为中高速移动UE。
优选实施例一
本发明优选实施例一的技术方案可以应用于图1的组网形式中。图1中，F2天线指向F1覆盖边界来提供小区边缘的吞吐量。F1提供足够的覆盖，但F2由于较大的路径损耗可能会有覆盖盲区。移动性基于F1覆盖。
高速移动UE由F1小区提供服务，只支持目标小区为F1小区的切换和目标小区为F2补盲小区的切换。低速移动UE在重叠覆盖区域，由负载均衡算法指定目标小区或不切换，其他地区满足A3测量上报条件，进行切换。如图8所示：
第一步：判断UE是否为中高速移动状态，如是，转入步骤二；否则，转入步骤三；
第二步：如果UE为中高速移动状态，为其配置测量对象为F1的A3测量事件，以及测量对象为F2的A5测量事件，且测量事件A5中的th1小于th2。
第三步：如果UE为低速移动状态，为其配置测量对象为F1和F2的测量事件A3和测量事件A5，且测量事件A5中th3大于th4。
一旦网络侧接收到UE的测量结果，测量配置模块的具体步骤为：
第一步：判断UE是否为中高速移动状态，如是，转入步骤二；否则，转入步骤三；
第二步：如果接收到的是测量对象为F1或测量对象为F2的A3测量事件，则UE移动到了F1或F2小区的覆盖范围，判定切换，转入步骤七；否则，转入步骤六；
第三步：如果UE为低速移动状态，再判断测量事件是否为测量对象为F1或F2的测量事件A3，如是，则UE移动到了信号更好的地区，判定切换，转入步骤七；否则，转入步骤四；
第四步：判断测量对象为F1或F2的测量事件是A5，如是，转入步骤五；否则，转入步骤六；
第五步：再判断目标小区比本小区的负荷的差值是否大于一定的门限，如是，转入步骤七；否则，两个小区负荷相近，则转入步骤六；
第六步：判断不进行小区切换；
第七步：判定进行小区切换。
优选实施例二
本发明优选实施例二的技术方案可以应用于图2的组网形式中。图2中，频点F1覆盖的小区范围内部署了多个用于补热的、频点为F2的微小区，以及在频点F1覆盖的小区范围外部署了多个用于补盲的、频点F2的微小区。移动性基于F1覆盖。
高速移动UE由F1小区提供服务，只支持目标小区为F1小区的切换和补盲地区目标小区为F2小区的切换。低速移动UE在重叠覆盖区域，由负载均衡算法指定目标小区是否不切换，其他地区满足A3测量上报条件，进行切换。如图9所示：
第一步：判断UE的移动状态；
第二步：如果UE为中高速移动状态，为其配置测量对象为F1的A3测量事件，以及测量对象为F2的A5测量事件，且测量事件A5中的th1小于th2。
第三步：如果UE为低速移动状态，为其配置测量对象为F1、F2的A3和A5测量事件，且测量事件A5中th3大于th4。
一旦网络侧接收到UE的测量结果，测量配置模块的具体步骤为：
第一步：判断UE是否为中高速移动状态，如是，转入步骤二；否则，转入步骤三；
第二步：如果接收到的是测量对象为F1或测量对象为F2的A3测量事件，则UE移动到了F1或F2小区的覆盖范围，判定切换，转入步骤七；否则，转入步骤六；
第三步：如果UE为低速移动状态，再判断测量事件是否为测量对象为F1或F2的测量事件A3，如是，则UE移动到了信号更好的地区，判定切换，转入步骤七；否则，转入步骤四；
第四步：判断测量对象为F1或F2的测量事件是A5，如是，转入步骤五；否则，转入步骤六；
第五步：再判断目标小区比本小区的负荷的差值是否大于一定的门限，如是，转入步骤七；否则，两个小区负荷相近，则转入步骤六；
第六步：判定不进行小区切换；
第七步：判定进行小区切换。
综上所述，本发明实施例达到了以下技术效果：解决了相关技术中对于不同移动速度的终端采用同样的测量事件而导致的上报大量的测量报告问题，针对不同的UE配置不同的测量配置，减少不必要的切换和测量上报，实现了结合UE的移动状态，针对不同的UE配置不同的测量配置，做出不同的判决的方案。
