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公开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、本公开的一些方面相一致的装置和方法的例子。
本公开一示例性实施例提供了一种小区切换的测量参数的管理的方法，该方法可以由飞行器实现。其中，飞行器可以是无人直升机、无人飞艇等。
飞行器可以包括处理器、存储器、收发器、飞行部件等部件。处理器可以为CPU(Central Processing Unit，中央处理单元)等，可以用于计算目标测量参数的相关处理。收发器可以用于接收基站发送的目标参数与小区切换的测量参数的对应关系等。存储器可以为RAM(Random Access Memory，随机存取存储器)、Flash(闪存)等，可以用于存储接收到的数据、处理过程所需的数据、处理过程中生成的数据等，如目标参数与小区切换的测量参数的对应关系等。飞行部件可以包括电动机、螺旋桨等，电动机用于提供飞行动力，螺旋桨用于推动气流以实现飞行器的飞行。
本发明实施例提供了一种小区切换的测量参数的管理方法，如图1所示，相应步骤可以如下：
在步骤101中，在飞行过程中，获取目标参数，目标参数是随高度而变化的能够用于表征飞行器所在高度的参数。
在实施中，飞行器在飞行过程中，对目标参数进行检测，从而获取到目标参数，用以后续对小区切换的测量参数进行确定。
在步骤102中，根据目标参数，确定小区切换的目标测量参数。
其中，小区切换的测量参数用于判定小区切换，当设备(飞行器或其它终端)检测到某小区的信号强度持续满足小区切换条件，且持续时长达到测量参数时，进行小区切换。
在实施中，飞行器获取到目标参数后，根据目标参数，确定小区切换的目标测量参数。
在步骤103中，根据目标测量参数进行小区切换处理。
在实施中，飞行器确定目标测量参数后，判断飞行器是否需要进行小区切换，并进行相关处理。
本发明实施例提供了一种小区切换的测量参数的管理方法，其中，测量参数可以为触发时长或Hys(hysteresis parameter，滞后值)等，本实施例以测量参数为触发时长为例进行方案详细说明，其它情况与之类似，本实施例不再赘述。如图2所示，小区切换的测量参数的管理方法的处理步骤可以如下：
在步骤201中，接收基站发送的第一通知消息，第一通知消息用于指示飞行器检测目标参数。
在实施中，基站可以预先记录有飞行器需要检测的目标参数，该目标参数具体采用哪种参数可以由技术人员预先配置。在飞行器接入基站后，基站向飞行器发送第一通知消息，如图3所示，例如RRC信令，第一通知消息指示飞行器检测目标参数。飞行器接收到第一通知消息后，对第一通知消息进行解析，得知飞行器检测何种目标参数，然后飞行器可以对目标参数进行测量，得到目标参数。
在步骤202中，在飞行过程中，获取目标参数，目标参数是随高度而变化的能够用于表征飞行器所在高度的参数。
在实施中，用户想要控制飞行器起飞时，可以先将飞行器放置稳定，打开飞行器的开关，操作遥控器使飞行器进行飞行并控制飞行器的飞行方向。飞行器开启后，接收到基站的信号后，进而可以与基站建立连接。成功接入基站以后，飞行器可以按照预设的检测周期对参数进行检测，每当达到预设的检测周期时，飞行器会对目标参数进行测量，用以后续对小区切换的触发时长进行确定。
可选地，目标参数可以是高度数值参数、检测到的除当前已接入小区之外的其它小区的数目参数、检测到的除当前已接入小区及其邻小区之外的其它小区的数目参数、和检测到的小区数目的增速参数中的一个或多个。
其中，小区数目的增速参数为，飞行器在升高单位高度时，检测到的小区数目的增量。
在实施中，目标参数可以有多种表现形式。
情况一，对于目标参数为高度数值参数的情况，飞行器检测目标参数的处 理可以如下：飞行器可以通过激光测距或3D(3Dimensions，三维)GPS(Global Positioning System，全球定位系统)，对当前位置的高度进行测量(单位可以是米)，如图4(a)，得到的数值作为检测到的目标参数。
情况二，对于目标参数为检测到的除当前已接入小区之外的其它小区的数目参数的情况，飞行器检测目标参数的处理可以如下：基站对应每个小区都会周期性的广播同步信号和辅同步信号，在同步信号和辅同步信号中携带有小区标识。因为不同小区的信号覆盖范围会有重叠，所以飞行器一般能够同时(可以是一个较小的预设时长内)检测到多个小区的信号。飞行器从当前检测到的各信号中，获取小区标识，如图4(b)，并统计除当前已接入小区之外的其它小区的小区标识的数目，作为检测到的目标参数。或者，在统计小区标识的数目时，可以只对信号强度大于预设门限值的消息中携带的小区标识进行数目统计。
情况三，对于目标参数为检测到的除当前已接入小区及其邻小区之外的其它小区的数目参数的情况，飞行器检测目标参数的处理可以如下：服务器可以按照上述情况二的处理方式，得到飞行器从当前检测到的各消息中获取的小区标识，然后获取当前接入小区的邻小区列表，将飞行器检测到的所有小区标识与邻小区列表进行对比，在所有小区标识中去除掉邻小区列表中包含的小区标识，并去除掉当前已接入小区的小区标识，然后统计剩下的小区标识的数目，将该数目作为检测到的目标参数。其中，当前已接入小区的邻小区列表可以是飞行器预先存储的，也可以是基站发送给飞行器，飞行器接收并存储的。
情况四，对于目标参数为检测到的小区数目的增速参数的情况，飞行器检测目标参数的处理可以如下：如图4(c)，服务器可以按照上述情况一的处理方式，检测飞行器的高度，每当上升单位高度时，采用与上述情况二类似的处理方式，得到能够同时检测到的小区的数目，并记录此小区的数目，同时，获取上一个单位高度检测的小区的数目，进而，计算升高单位高度后小区数目的增量，除以单位高度，得到的增速作为检测到的目标参数。
对于上述情况，本发明实施例可以单独使用也可以组合使用，即，目标参数可以是上述情况中的任意一种，也可以是任意多种。
在步骤203中，根据目标参数，确定小区切换的目标触发时长。
其中，小区切换的触发时长用于判定小区切换，当设备(飞行器或其它终端)检测到某小区的信号强度持续满足小区切换条件，且持续时长达到触发时 长时，进行小区切换。在此对应关系中，对于目标参数是高度数值参数的情况，高度越高，对应的触发时长越长；对于目标参数是检测到的除当前已接入小区之外的其它小区的数目参数的情况，数目越大，对应的触发时长越长；对于目标参数为检测到的除当前已接入小区及其邻小区之外的其它小区的数目参数的情况，数目越大，对应的触发时长越长；对于目标参数为检测到的小区数目的增速参数的情况，增速越大，对应的触发时长越长。
可选地，如图5所示，包括如下步骤203’：根据预先存储的目标参数与调整因子之间的对应关系，确定当前获取的目标参数对应的目标调整因子。获取目标调整因子与预先存储的小区切换的基准触发时长之间的乘积，得到小区切换的目标触发时长。
在实施中，技术人员可以预先设置基准触发时长，可以基于实际情况任意设置，在设置时可以考虑小区的密度。另外，技术人员还可以预先设置目标参数与调整因子的对应关系，可以以表的形式进行存储。其中，调整因子的取值可以基于实际情况任意设置，在设置时可以考虑具体选择的目标参数。上述基准触发时长和对应关系表可以直接存储在飞行器的存储器中，也可以由基站发送给飞行器进行存储。在上述对应关系中，对于目标参数是高度数值参数的情况，高度越高，对应的调整因子越大；对于目标参数是检测到的除当前已接入小区之外的其它小区的数目参数的情况，数目越大，对应的调整因子越大；对于目标参数为检测到的除当前已接入小区及其邻小区之外的其它小区的数目参数的情况，数目越大，对应的调整因子越大；对于目标参数为检测到的小区数目的增速参数的情况，增速越大，对应的调整因子越大。
飞行器检测到目标参数后，在上述对应关系表中，查找到该取值对应的调整因子(即目标调整因子)。将目标调整因子与基准触发时长相乘，得到的乘积即为目标触发时长。
例如，预先设置的基准触发时长为1024ms，目标参数与调整因子的对应关系表如表1所示。
表1
目标参数 调整因子
100 1
200 2
300 3
400 4
目标参数为高度数值参数，且飞行器检测到高度为200米，根据表1可以得知，目标参数为200米时对应的调整因子为2，将调整因子2与基准触发时长1024ms进行相乘，2×1024ms＝2048ms，从而可知，飞行器当前位置对应的目标触发时长为2048ms。
再例如，预先设置的基准触发时长为512ms，目标参数与调整因子的对应关系如表2所示。
表2
目标参数 调整因子
5 1
10 2
15 3
20 4
目标参数为检测到的除当前已接入小区之外的其它小区的数目参数，且飞行器检测到的小区的数目为15个，根据表2可以得知，目标参数为15个时对应的调整因子为3，将调整因子3与基准触发时长512ms进行相乘，3×512ms＝1536ms，从而可知，飞行器当前位置对应的目标触发时长为1536ms。
可选地，如图6所示，还可以包括如下步骤200：接收基站发送的第二通知消息，第二通知消息中携带有目标参数与调整因子的对应关系及基准触发时长。存储对应关系和基准触发时长。
其中，第二通知消息和第一通知消息可以是同一消息，也可以是不同的消息。
在实施中，技术人员可以预先设置目标参数与调整因子的对应关系，并以表的形式在基站中进行存储。另外，技术人员还可以预先设置基准触发时长，并在基站中进行存储。在飞行器接入基站时，基站可以向飞行器发送第二通知消息，该第二通知消息中携带上述对应关系和基准触发时长。飞行器接收基站发送的第二通知消息后，将第二通知消息中的目标参数与调整因子的对应关系和基准触发时长存储起来，用以后续计算目标触发时长。
在步骤204中，根据目标触发时长进行小区切换处理。
在实施中，飞行器确定目标触发时长后，存储目标触发时长。如果飞行器检测到某小区的信号强度与当前接入小区的信号强度之差大于预设门限值，且 此差值持续大于预设门限值的时长达到目标触发时长，则无人机开始执行小区切换的处理，由当前接入的小区，切换到此信号较强的小区，如图7。该预设门限值的取值范围可以是5-20dBm，如预设门限值为10dBm。
本公开实施例中，获取目标参数，所述目标参数是随高度而变化的能够用于表征飞行器所在高度的参数；根据所述目标参数，确定小区切换的目标触发时长；根据所述目标触发时长进行小区切换处理。这样，可以使无人机在不同的高度时具有不同的触发时长，通过对应关系中的数值设置，可以使无人机在较高的高度飞行时，具有较长的触发时长，不会很频繁的进行小区切换，从而使数据传输的失败率降低。
基于相同的技术构思，本发明实施例还提供了一种飞行器，如图8所示，该飞行器包括：检测模块810，确定模块820，第一存储模块830。

可选地，所述目标参数包括高度数值参数、检测到的除当前已接入小区之外的其它小区的数目参数、检测到的除当前已接入小区及其邻小区之外的其它小区的数目参数、和检测到的小区数目的增速参数中的一个或多个。
可选地，所述飞行器还包括：

可选地，所述确定模块820，用于：

可选地，所述测量参数包括触发时长。
本公开实施例中，获取目标参数，所述目标参数是随高度而变化的能够用于表征飞行器所在高度的参数；根据所述目标参数，确定小区切换的目标测量参数；根据所述目标测量参数进行小区切换处理。这样，可以使无人机在不同的高度时具有不同的测量参数，通过对应关系中的数值设置，可以使无人机在较高的高度飞行时，具有较长的测量参数，不会很频繁的进行小区切换，从而使数据传输的失败率降低。
需要说明的是：上述实施例提供的飞行器在管理小区切换的测量参数时，仅以上述各功能模块的划分进行举例说明，实际应用中，可以根据需要而将上述功能分配由不同的功能模块完成，即将装置的内部结构划分成不同的功能模块，以完成以上描述的全部或者部分功能。另外，上述实施例提供的飞行器与小区切换的测量参数的管理方法实施例属于同一构思，其具体实现过程详见方法实施例，这里不再赘述。
