Description

一种预测、上报小区信号强度的方法和用户设备 技术领域
本发明涉及通信领域，尤其涉及一种预测、上报小区信号强度的方法和用户设备。
背景技术
在蜂窝移动通信(Cellular Mobile Communication)系统下，用户使用用户设备(User Equipment，UE)通话的时候从服务小区的覆盖范围移动到该服务小区的相邻小区的覆盖范围时，该服务小区的信号会越来越差，相邻小区的信号强度会越来越强，为了确保通话不中断，UE需要从服务小区切换到相邻小区。即UE断开与信号较差的服务小区的通信连接，并重新连接到信号较好的相邻小区以保证通信的连续性。请参照图1，图1是现有技术中的一种用户设备进行小区切换的交互示意图。图1中包含用户设备、上述服务小区所对应的基站、上述相邻小区对应的基站，例如其他基站、移动管理实体和网关设备之间的交互，其中，小区切换主要由用户设备、基站和其他基站来完成，具体过程如下。
基站根据用户设备当前的通信情况，向用户设备下发测量配置。用户设备根据接收到的测量配置对服务小区和该服务小区的邻区进行信号强度的测量，并在测量到的信号强度满足上报测量报告的条件时，向基站上报测量报告，该测量报告包含该服务小区的信号强度和该服务小区的邻区的信号强度。基站接收该测量报告并解析出其中的信号强度后，基于解析出的信号强度判断是否满足切换小区的条件，若满足则向其他基站发送切换请求。其他基站根据接收到的切换请求生成无线资源相关配置信息和用户设备标识，并将包含该无线资源相关配置信息和用户设备标识的切换应答发送给该基站。该基站根据接收到的切换应答向用户设备发送包含上述无线资源相关配置信息和用户设备标识的无线资源控制协议(Radio Resource Control，RRC)消息。用户设备在接收到RRC消息后，根据RRC消息连接到该其他基站。
现有技术的缺陷在于，从该基站判断出满足切换小区的条件到该基站向用户设备发送RRC消息大概需要持续2～5秒，可能导致该基站向用户设备发送RRC消息指示用户设备进行切换时的服务小区的实际信号强度已经不是用户设备测量到的服务小区的信号强度。特别是当用户设备处于疾驰的汽车、火车(特别是高铁)上时，服务小区的实际信号强度和用户设备测量到的信号强度之间差别比较大，甚至服务小区的信号强度已经弱到无法支撑用户设备接收该RRC消息。

基于在所述第一预设时间段内的所述服务小区的信号强度，所述用户设备判断所述服务小区的信号强度是否呈下降趋势；
若所述服务小区的信号强度呈下降趋势，所述用户设备预测在第二预设时间的所述服务小区的信号强度。
通过上述步骤，用户设备在判断出服务小区的信号强度呈下降趋势时，根据该下降趋势的变化规律预测出服务小区在之后的第二预设时间的信号强度，这样可以提前预测出服务小区的信号强度。

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地描述，显然，所描述的实施例仅仅是本发明一部分实施例，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作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例所描述的用户设备可以是手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(MID，mobile internet device)、可穿戴设备(例如智能手表(如iWatch等)、智能手环、计步器等)或其他可安装部署用户识别卡(Subscriber Identity Module，SIM)的终端设备或通信模块。
实施例一：
请参见图2，图2是本发明实施例提供的一种预测小区信号强度的方法流程示意图，该方法包括：
步骤S201：用户设备接收测量配置，对服务小区进行信号强度的测量。
具体地，蜂窝网络中可以包括多个小区，每个小区都可以对应有自身的基站。用户设备当前处于服务小区和该服务小区的邻区(相邻小区)的信号覆盖范围内，该服务小区(serving)除了包括一个主小区(Primary Cell，PCell)外，还可以包括至少一个辅小区(Secondary Cell，SCell)，当包括辅小区(Secondary Primary Cell，SCell)时，信号强度最好的辅小区(SCell)为主控辅小区(PSCell)，用户设备通过上述主小区建立无线连接(RRC connected)，进入无线连接状态后接收该主小区对应的基站发送的测量配置(Measurement Control)。
该测量配置包括A1、A2、A3、A4、A5、A6、B1、B2等事件中至少一个事件的事件标识。该事件标识可以作为用户设备判断是否需要向基站上报测量报告(Measurement Report)的条件。由于用户设备无论基于上述哪个事件的事件标识进行判断是否需要向基站上报测量报告，均至少需要测量上述主小区(PCell)的信号强度，因此该测量配置还包括该主小区(PCell)的频率。用户设备接收到基站发送的该测量配置之后，会启动对服务小区进行信号强度 的测量，具体包括对该服务小区的主小区(PCell)的信号强度的测量。
为了便于理解本发明实施例中的测量配置，以下提供通信协议中的事件A1、A2、A3、A4、A5、A6、B1和B2的具体内容：事件A1，服务小区的信号强度比绝对阈值高(英文：Event A1，Serving becomes better than absolute threshold)；事件A2，服务小区的信号强度比绝对阈值低(英文：Event A2，Serving becomes worse than absolute threshold)；事件A3，邻区的信号强度比服务小区的信号强度高于特定阈值(英文：Event A3，Neighbour becomes amount of offset better than PCell/PSCell)；事件A4，邻区的信号强度比绝对阈值高(英文：Event A4，Neighbour becomes better than absolute threshold)；事件A5，服务小区的信号强度比绝对阈值1低且邻区的信号强度比绝对阈值2高(英文：Event A5，PCell/PSCell becomes worse than absolute threshold 1 AND neighbour becomes better than another absolute threshold 2)；事件A6，邻区的信号强度比服务小区的辅小区高于特定阈值(英文：Event A6，Neighbour becomes amount of offset better than SCell)；事件B1，异系统的邻区的信号强度比绝对阈值高(英文：Event B1，Inter RAT neighbour becomes better than absolute threshold，其中，RAT全称为Radio Access Technology)；事件B2，服务小区的信号强度比绝对阈值1低且异系统的邻区的信号强度比绝对阈值2高(英文：Event B2，PCell becomes worse than absolute threshold 1 AND inter RAT neighbour becomes better than another absolute threshold 2)。
当上述基站需要用户设备以事件A1作为判断是否上报测量报告的条件时，上述测量配置包含事件A1的事件标识、事件A1的绝对阈值(threshold)、主小区频率和信号强度标识，其中，信号强度标识可以包括参考信号接收功率(Reference Signal Received Power，RSRP)和参考信号接收质量(Reference Signal Received Quality，RSRQ)中至少一项的标识；用户设备会根据该测量配置测量该主小区频率对应的主小区的信号强度。测量到该主小区的信号强度后，将该主小区的信号强度与该绝对阈值(threshold)进行比较，当该主小区的信号强度高于该绝对阈值(threshold)时，表明满足上报A1对应的测量报告的条件。

当服务小区包含辅小区时，基站还可以指示用户设备以A6事件作为判断是否上报测量报告的条件，当指示用户设备以事件A6作为判断是否上报测量报告的条件时，上述测量配置包含事件A6的事件标识、主小区频率、辅小区频率、系统标识、邻区频率、邻区标识、信号强度标识和A6的特定阈值，其中，信号强度标识具体包括RSRP和RSRQ中至少一项的标识；用户设备会根据该测量配置测量该主小区频率对应的主小区的信号强度、辅小区频率对应的辅小区的信号强度，以及系统标识、邻区频率和邻区标识共同确定的与该主小区同系统的信号强度。测量到该主小区的信号强度、该辅小区的信号强度和该邻区的信号强度后，将该邻区的信号强度与该辅小区的信号强度进行比较，当该邻区的信号强度比该辅小区的信号强度高出的量超过上述特定阈值时，表明满足上报A6对应的测量报告的条件。
当上述基站需要用户设备以事件B1作为判断是否上报测量报告的条件时，上述测量配置包含事件B1的事件标识、B1的绝对阈值(threshold)、主小区频率、系统标识、邻区频率、邻区标识和信号强度标识，其中，信号强度标识具体包括RSRP和RSRQ中至少一项的标识，用户设备会根据该测量配置测量该主小区频率对应的主小区，以及该系统标识、邻区频率和邻区标识共同确定的与该主小区异系统的信号强度。测量到该主小区的信号强度和该邻区的信号强度后，将该邻区的信号强度与该绝对阈值(threshold)进行比较，当该邻区的信号强度高于该绝对阈值(threshold)时，表明满足上报B1对应的测量报告的条件。

进一步地，上述同系统是指网络制式相同，例如，相邻小区和主小区均为第四代移动通信技术(The 4th Generation Telecommunication，4G)制式；上述异系统是指网络制式不相同，例如，相邻小区为第三代移动通信技术(The 3rd Generation Telecommunication，3G)制式，主小区为4G制式。
步骤S202：在第一预设时间段内，所述用户设备记录所述服务小区的信号强度。
具体地，启动对服务小区进行信号强度的测量后，在第一预设时间段内对测量到的信号强度进行记录。上述第一预设时间段可以为用户设备中的默认配置，或者为基站下发给用户设备的时间参数。在记录信号强度时，记录的时间间隔可根据需要进行设置，在该第一预设时间段内，记录的信号强度的值为多个。当启动对信号强度的测量后，多久后开始记录也可以根据需要进行设置，例如，可以在启动测量后立即进行记录。
以下举例来描述如何在该第一预设时间段记录信号强度，假设该第一预设时间段为5秒，可以记录该5秒内的第0、1、2、3、4和5秒处的信号强度。若开始记录的时间为用户设备上的计时器记录的第3000秒，那么在5秒内，分别记录第3000秒、3001秒、3002秒、3003秒、3004秒和3005秒的信号强度。请参照表1，为本发明实施例提供的第一预设时间段内，在各个记录的时间点记录的信号强度的数据。
用户设备中计时器的时间 第一预设时间段中的时刻 信号强度
第3000秒 第0秒 -83db
第3001秒 第1秒 -86db
第3002秒 第2秒 -89db
第3003秒 第3秒 -92db
第3004秒 第4秒 -91db
第3005秒 第5秒 -94db
表1
需要说明的是，上述例子是通过等时间间距来记录信号强度，但是在其他的实施例中相邻的时间间距之间也可以设置为满足预设的函数关系。例如，每一次记录的时间间隔都比上一次记录的时间间隔小0.1秒，那么同样以第一预设时间段为5秒为例，用户设备需要记录第0、1、1.9、2.7、3.4、4、4.5和4.9秒处的信号强度，相邻的时间间距之间满足预设的函数关系的例子还有很多，此处不一一举例。
步骤S203：基于在所述第一预设时间段内的所述服务小区的信号强度，所述用户设备判断所述服务小区的信号强度是否呈下降趋势。
具体地，由于该第一预设时间段内记录了服务小区在多个时间点的信号强度，因此可以根据该多个时间点的信号强度，判断该服务小区的信号强度是否呈下降趋势。
在一种可选的方案中，上述下降趋势是指：第一预设时间段的结束时间点的信号强度与起始时间点的信号强度的差值大于预先设定的阈值，该阈值的大小可以根据实际需要来设定。
在又一种可选的方案中，上述下降趋势是指：在该第一预设时间段内，第一预设时间段的起始时间点的信号强度与结束时间点的信号强度的差值大于预先设定的第一下降阈值，且在第一预设时间段内的多个时间点中的某个时间点的信号强度比该某个时间点的前一个时间点的信号强度大时，该某个时间点的信号强度与该某个时间点的前一个时间点的信号强度的差值不超过预先设定的第一上升阈值。
举例来说，假设预先设定的第一下降阈值为10db，第一上升阈值为6db，并且以用户设备中计时器记录的第3000秒为起始记录点的5秒内，记录的第3000秒的信号强度为-83db，第3001秒的信号强度为-86db，第3002秒的信号强度为-89db，第3003秒的信号强度为-92db，第3004秒的信号强度为-91db，第3005秒的信号强度为-94db。由以上数据可以得到，在该5秒内，信号强度的下降的幅度为第3000秒的-83db减去第3005秒的-94db，-83db减去-94db等于11db，大于第一下降阈值10db；第3004秒的信号强度比第3003秒的信号强度大，大过的幅度为-91db减去-92db等于1db，小于第一上升阈值6db，因此可以确定服务小区的信号强度呈下降趋势。
请参照图2A，图2A是本发明实施例提供的服务小区的信号强度的下降趋势示意图。在图2A中，第3001秒之前信号强度在增强，而第3001～3005秒信号强度总体持续下降，虽然在第3004秒处略有上升，但是上升的幅度特别小(上升幅度小于预设的第一上升阈值)，因此第3000～3005秒信号强度呈下降趋势。
步骤S204：若所述服务小区的信号强度呈下降趋势，上述用户设备预测在第二预设时间的所述服务小区的信号强度。
具体地，当判断出该服务小区的信号强度呈下降趋势时，进一步根据记录的多个时间点的信号强度来确定该下降趋势的大致下降规律，进而根据该下降规律预测出服务小区在第二预设时间的信号强度。
在一种可选方案中，该服务小区的信号强度的下降幅度与下降所持续的时间近似成比例关系，例如，假设第一预设时间段为5秒，其中，第0、1、2、3、4、5秒记录的信号强度分别为：-83db、-86db、-89db、-92db、-91db、-94db，那么记录开始时的信号强度减去记录结束时的信号强度，然后除以记录所持续的时间得到的数据为：((-83)-(-94))/5＝2.2db，即服务小区的信号强度每隔1秒大约下降2.2db。服务小区的信号强度呈下降趋势时，可以认为服务小区在随后的一段时间里信号强度会按照该下降趋势持续下降。因此可以根据该下降趋势大致推算出第二预设时间的信号强度。
上述第二预设时间是记录完上述第一预设时间段的信号强度之后的一个时间点，可以根据预先定义的规则推导得到，例如，记录完上述第一预设时间 段的信号强度，再间隔预设时间(如3秒)后的时间为上述第二预设时间。如果开始记录该服务小区的信号强度的时间为用户设备中的计时器记录的第3000秒，用户设备共记录了5秒内的信号强度，那么3000+5+3＝3008秒，即第3008秒为上述第二预设时间；如果后续用户设备又在第4000秒开始记录5秒内的信号强度，那么4000+5+3＝4008秒，即第4008秒为上述第二预设时间，依次类推。也即是说，用户设备每次记录第一预设时间段的信号强度后，都会根据记录时的时间以及预先设置的一个间隔时间来推导出一个第二预设时间。
如果记录结束后间隔3秒的时间为上述第二预设时间，那么可以推导出该第二预设时间的信号强度为：记录的最后一个信号强度减去估计的每秒信号强度下降值乘以间隔时间。以上述为例，(-94)-2.2*3＝-100.6db。
需要说明的是，服务小区的信号强度的下降幅度与下降所持续的时间还可能成其他的线性关系，具体为哪种线性关系可以对已经记录的信号强度进行数学建模得到。
在一种可选的方案中，用户设备预测出上述服务小区在第二预设时间的信号强度后，如果需要向基站上报测量报告，可以在该测量报告中服务小区的信号强度的字段中封装预测的该服务小区在第二预设时间的信号强度，而不是像现有技术那样封装当前测量到的该服务小区的信号强度。
通过执行上述步骤S201～S204，用户设备判断出服务小区的信号强度呈下降趋势时，根据该下降趋势的变化规律预测出服务小区在之后的第二预设时间的信号强度，这样可以提前预测出服务小区的信号强度。
更进一步的，在执行上述步骤S201～S204所描述的预测服务小区的信号强度之后，还可以通过执行步骤S205和S206向基站上报预测到的该服务小区的信号强度。
请参见图3，图3是本发明实施例提供的一种预测小区信号强度的方法流程示意图，用于预测服务小区的信号强度并上报该预测到的信号强度，其中，步骤S205和S206的详细描述如下。
步骤S205：所述用户设备基于预测的所述第二预设时间的所述服务小区的信号强度，判断是否满足上报条件。
具体地，该上报条件具体为上述上报测量报告的条件，该测量报告可以指 示用户设备以事件A3、A5和B2中至少一项作为判断是否上报测量报告的条件，用户设备以事件A3、A5和B2中至少一项作为判断条件时，均涉及到与服务小区的信号强度进行对比，更确切地说是与服务小区的主小区进行信号强度的对比，在具体对比时，是与预测的第二预设时间该服务小区的信号强度对比，而不是像现有技术那样与当前测量到的该服务小区的信号强度对比。
举例来说，假设用户设备在第3000秒接收的测量报告指示用户设备将事件A3(即邻区的信号强度比服务小区的信号强度高于特定阈值)作为判断是否上报测量报告的条件，用户设备在第3005秒测量到该服务小区的信号强度为-94db，测量到该服务小区的邻区的信号强度为-97db，并根据3000～3005秒的该服务小区的信号强度预测该服务小区在第3008秒(第二预设时间)的信号强度为-100.6db。那么，用户设备将上述-100.6db与上述-97db比较来判断是否需要向基站发送A3对应的测量报告，而不是像现有技术那样将上述-94db与上述-97db比较来判断是否需要向基站发送A3对应的测量报告。用户设备以A5或B2为条件来判断是否需要向基站上报测量报告时的原理可以对应参照以A3为判断条件时的描述，此处不一一描述。
步骤S206：若满足上报条件，所述用户设备上报预测的所述第二预设时间的所述服务小区的信号强度。
具体地，如果满足向基站上报测量报告的条件，则将预测的该第二预设时间的该服务小区的信号强度作为测量报告中的该服务小区的信号强度。
举例来说，假设满足向基站发送A3对应的测量报告的条件，且该服务小区在第3005秒测量到的信号强度为-94db，预测在第二预设时间的信号强度为-100.6db，那么在该A3对应的测量报告中将-100.6db作为该服务小区的信号强度发送给基站。这样一来，该基站就会基于该-100.6db判断是否满足切换小区的条件，若满足则该基站执行切换小区的操作。另外，发送A5或B2对应的测量报告的原理与发送A3对应的测量报告的原理相同，此处不一一描述。
通过执行步骤S205和S206，在以事件A3、A5和B1中至少一项作为判断是否上报测量报告的条件时，用户设备将预测的服务小区在第二预设时间的信号强度与相应事件中的其他量(如邻区信号强度、绝对阈值等)进行比较来判断是否满足上报测量报告的条件，若满足则将该预测的信号强度通过测量报 告上报给基站，以使该基站基于该预测的信号强度而不是实际的信号强度进行小区切换，相当于提前促使该基站进行小区切换，避免了切换的过程中该服务小区的信号强度下降到无法支撑该用户设备接收RRC消息，保证了用户设备顺利从该服务小区切换到其他小区。
为了进一步完善本发明实施例的方案，在执行上述步骤S201～S204所描述的预测服务小区的信号强度时，还可以通过执行步骤S207来选择合适的时机预测服务小区的信号强度。
请参见图4，在步骤S201之后，在步骤S202之前，本发明实施例提供的一种预测小区信号强度的方法还包括：
步骤S207：所述用户设备判断所述服务小区的信号强度是否小于第一阈值；
若所述服务小区的信号强度小于所述第一阈值，执行步骤S202。
具体地，当执行了步骤S201，即启动了对当该前服务小区的信号强度的测量之后，判断测量到的该服务小区的信号强度是否小于第一阈值，如果小于则开始记录该服务小区在第一预设时间段的信号强度；如果大于，则不记录该服务小区在第一预设时间段的信号强度。
需要说明的是，该第一阈值可以为预先配置在该用户设备中的一个表征信号强度大小的参考值，或者为上述基站发送给该用户设备的一个表征信号强度大小的参考值。可选的，当该第一阈值由该基站发送给该用户设备时，该第一阈值的大小可以与上述事件A2中的绝对阈值(threshold)相等。
通过执行步骤S207，用户设备在服务小区的信号强度弱到小于第一阈值时才开始记录该服务小区在第一预设时间段内的信号强度，而无需记录任意时刻的该服务小区的信号强度，极大地减小了该用户设备的存储压力和运算压力。
为了进一步完善本发明实施例的方案，还可以先判断服务小区的信号强度是否小于第一预设阈值，当判断结果为是时再进行记录和预测，最终用户设备上报预测的第二预设时间的服务小区的信号强度给基站，对应的流程如图4A所示，其中各个步骤的详细描述可以对应参照上述相同步骤的描述，此处不再赘述。
更进一步的，在执行上述步骤S201～S204所描述的预测服务小区的信号强度时，还可以通过执行步骤S208～S211来预测该服务小区的邻区的信号强度。
请参见图5，图5是本发明实施例提供的一种预测小区的信号强度的方法流程示意图，用于预测服务小区和该服务小区的邻区的信号强度，其中，步骤S208～S211的详细描述如下。
步骤S208：所述用户设备接收测量配置，对所述服务小区的邻区进行信号强度的测量。
具体地，本发明实施例的执行流程中除了包括S201等步骤外，还包含S208，也即是说，用户设备接收到该测量配置后，既要对服务小区进行信号强度的测量，也要对该服务小区的邻区进行信号强度的测量。该测量配置指示用户设备以事件A3、A4、A5、A6、B1和B2中至少一项作为判断是否满足上报测量报告的条件时，该测量配置中包含邻区频率、事件标识、信号强度标识(指示测量哪些量)等，用于指示用户设备测量该邻区频率指示的邻区的信号强度。
步骤S209：在所述第一预设时间段内，所述用户设备记录所述服务小区的邻区的信号强度。
具体地，记录服务小区的邻区的信号强度与记录该服务小区的信号强度的原理相同(即与步骤S202的原理相同)，区别在于步骤S202记录的对象为服务小区的信号强度，而步骤S209记录的是服务小区的邻区的信号强度。
步骤S210：基于在所述第一预设时间段内的所述服务小区的邻区的信号强度，所述用户设备判断所述服务小区的邻区的信号强度是否呈上升趋势。
具体地，由于该第一预设时间段内记录了该服务小区的邻区在多个时间点的信号强度，因此可以根据该多个时间点的信号强度，判断该服务小区的邻区的信号强度是否呈上升趋势。
在一种可选的方案中，上述上升趋势是指：在该第一预设时间段内，第一预设时间段的结束时间点的信号强度与起始时间点的信号强度的差值大于预先设定的阈值，该阈值的大小可以根据实际需要来设定。
在又一种可选的方案中，上述上升趋势是指：在该第一预设时间段内，第 一预设时间段的结束时间点的信号强度与起始时间点的信号强度的差值大于预先设定的第二上升阈值，且在第一预设时间段内的多个时间点中的某个时间点的信号强度比该某个时间点的前一个时间点的信号强度小时，该某个时间点的前一个时间点的信号强度与该某个时间点的信号强度的差值不超过预先设定的第二下降阈值。该服务小区的邻区的数量可以为一个也可以为多个。
举例来说，假设预先设定的第二上升阈值为10db，第二下降阈值为6db，并且以用户设备中计时器记录的第3000秒为起始记录点的5秒内，记录的第3000秒的信号强度为-94db，第3001秒的信号强度为-91db，第3002秒的信号强度为-92db，第3003秒的信号强度为-89db，第3004秒的信号强度为-86db，第3005秒的信号强度为-83db。由以上数据可以得到，在该5秒内，信号强度的上升幅度为第3005秒的-83db减去第3000秒的-94db，-83db减去-94db等于11db，大于第二上升阈值10db；第3002秒的信号强度比第3001秒的信号强度小，小于的幅度为-91db减去-92db等于1db，小于第二下降阈值6db，因此可以确定服务小区的信号强度呈上升趋势。
请参照图5A，图5A是本发明实施例提供的服务小区的邻区的信号强度的上升趋势示意图。在图5A中，该服务小区的邻区在第3000秒之前信号强度在比较平稳，而第3000～3005秒信号强度总体持续上升，虽然在第3001秒处略有下降，但是下降的幅度特别小(下降幅度小于预设的第二下降阈值)，因此判定该邻区在第3000～3005秒信号强度呈上升趋势。
步骤S211：若所述服务小区的邻区的信号强度呈上升趋势，所述用户设备预测在所述第二预设时间的所述服务小区的邻区的信号强度。
具体地，当判断出该服务小区的邻区的信号强度呈上升趋势时，进一步根据记录的多个时间点的信号强度来确定该上升趋势的大致上升规律，进而根据该上升规律预测出服务小区的邻区在第二预设时间的信号强度。
在一种可选方案中，该服务小区的邻区的信号强度的上升幅度与上升所持续的时间近似成比例关系，例如，假设第一预设时间段为5秒，其中，第0、1、2、3、4、5秒记录的信号强度分别为：-94db、-91db、-92db、-89db、-86db、-83db，那么记录结束时的信号强度减去记录开始时的信号强度，然后除以记录所持续的时间得到的数据为：((-83)-(-94))/5＝2.2db，即服务小区的邻区 的信号强度每隔1秒大约上升2.2db。服务小区的邻区的信号强度呈上升趋势时，可以认为服务小区的邻区在随后的一段时间里信号强度会按照该上升趋势持续上升。因此可以根据该上升趋势大致推算出该服务小区的邻区在第二预设时间点的信号强度。
上述第二预设时间是记录完上述服务小区的邻区在第一预设时间段的信号强度之后的一个时间点，可以根据预先定义的规则推导得到，例如，记录完服务小区的邻区在上述第一预设时间段的信号强度，再间隔预设时间(如3秒)后的时间为上述第二预设时间。如果开始记录该服务小区的邻区的信号强度的时间为用户设备中的计时器记录的第3000秒，用户设备共记录了5秒内的信号强度，那么3000+5+3＝3008秒，即第3008秒为上述第二预设时间；如果后续用户设备又在第4000秒开始记录5秒内的信号强度，那么4000+5+3＝4008秒，即第4008秒为上述第二预设时间，依次类推。也即是说，用户设备每次记录第一预设时间段的信号强度后，可以根据记录时的时间以及预先设置的一个间隔时间来推导出一个第二预设时间。
如果记录结束后间隔3秒的时间为上述第二预设时间，那么可以推导出该服务小区的邻区在第二预设时间的信号强度为：记录的最后一个信号强度加上估计的每秒信号强度上升值乘以间隔时间。以上述为例，(-83)+2.2*3＝-76.4db。
需要说明的是，服务小区的邻区的信号强度的上升幅度与上升所持续的时间还可能成其他的线性关系，具体为哪种线性关系可以对已经记录的信号强度进行数学建模得到。
在一种可选的方案中，用户设备预测出上述服务小区的邻区在第二预设时间的信号强度后，如果需要向基站上报测量报告，可以在该测量报告中服务小区的邻区的信号强度的字段中封装预测的该服务小区的邻区在第二预设时间的信号强度，而不是向现有技术那样封装当前测量到的该服务小区的邻区的信号强度。
通过执行上述步骤S208～S211，用户设备判断出服务小区的邻区的信号强度呈上升趋势时，根据该上升趋势预测该服务小区的邻区在上述第二预设时间的信号强度，这样可以提前预测出服务小区的邻区的信号强度。
为了进一步地完善本发明实施例的方案，在执行完步骤S201～S204以及 S208～S211所描述的预测服务小区的信号强度以及服务小区的邻区的信号强度之后，还可以通过执行步骤S212和S213来向基站上报预测到的该服务小区的邻区的信号强度。
请参见图6，图6是本发明实施例提供的一种预测小区信号强度的方法流程示意图，用于预测服务小区的信号强度和该服务小区的邻区的信号强度，并上报预测的该服务小区的邻区的信号强度，其中，步骤S212和S213的详细描述如下。
步骤S212：所述用户设备基于预测的所述第二预设时间的所述服务小区的邻区的信号强度，判断是否满足上报条件。
具体地，该上报条件具体为上述上报测量报告的条件，该测量报告可以指示用户设备以事件A3、A4、A5、B1和B2中至少一项作为判断是否上报测量报告的条件，用户设备以事件A3、A4、A5、B1和B2中至少一项作为判断是否上报测量报告的条件事件时，均涉及到与上述服务小区的邻区的信号强度进行对比，在具体对比时，是与预测的第二预设时间该服务小区的邻区的信号强度进行对比，而不是像现有技术那样与当前测量到的该服务小区的邻区的信号强度对比。
举例来说，假设用户设备在第3000秒接收的测量报告指示用户设备将事件A4(即服务小区的邻区的信号强度比绝对阈值高)作为判断是否上报测量报告的条件，用户设备在第3005秒测量到该服务小区的邻区的信号强度为-83db，并根据第3000～3005秒的该服务小区的邻区的信号强度预测该服务小区的邻区在第3008秒(第二预设时间)的信号强度为-76.4db。那么，用户设备将上述-76.4db与上述A4中的绝对阈值比较来判断是否需要向基站发送A4对应的测量报告，而不是像现有技术那样将上述-83db与上述A4中的绝对阈值比较来判断是否需要向基站发送A4对应的测量报告。用户设备以A3、A5、B1和B2中任一项为条件来判断是否需要向基站上报测量报告时的原理可以对应参照以A4为判断条件时的描述，此处不一一描述。
步骤S213：若满足上报条件，所述用户设备上报预测的所述第二预设时间的所述服务小区的邻区的信号强度。
具体地，如果满足向基站上报测量报告的条件，且该测量报告需要包含该 服务小区的邻区的信号强度时，则将预测的该第二预设时间的该服务小区的邻区的信号强度作为测量报告中的该服务小区的邻区的信号强度。
举例来说，假设满足向基站发送A4对应的测量报告的条件，且该服务小区的邻区在第3005秒测量到的信号强度为-83db，预测到该服务小区的邻区在第二预设时间的信号强度为-76.4db，那么在该A4测量报告中将-76.4db作为该服务小区的邻区的信号强度发送给基站。这样一来，基站就会基于该-76.4db判断是否满足将该用户设备的服务小区切换到该服务小区的邻区的条件，若满足该基站执行切换小区的操作。另外，发送A3、A5、B1和B2中任一项对应的测量报告的原理与发送A4对应的测量报告的原理相同，此处不一一描述。
通过执行步骤S212和S213，在以事件A3、A4、A5、A6、B1和B2中至少一项作为判断是否上报测量报告的条件时，用户设备将预测的服务小区的邻区在第二预设时间的信号强度与相应事件中的其他量(如服务小区信号强度、绝对阈值等)进行比较来判断是否满足上报测量报告的条件，若满足则将预测的该服务小区的邻区的信号强度通过测量报告上报给基站，以使该基站基于该预测的服务小区的邻区的信号强度而不是实际的服务小区的邻区的信号强度，来判断是否需要将该用户设备当前的服务小区切换到该服务小区的邻区。不至于将用户设备切换到该服务小区的邻区后，该服务小区的邻区的实际信号强度无法支撑该用户设备的正常通信。
为了进一步地完善本发明实施例的方案，还可以执行步骤S201～S206以及S208～S213，各个步骤的详细描述可以参照上述相同步骤的描述，此处不再赘述。
为了进一步地完善本发明实施例的方案，在执行完步骤S201～S204以及S208～S211所描述的预测服务小区的信号强度以及服务小区的邻区的信号强度时，还可以通过执行步骤S214来选择合适的时机预测服务小区的邻区的信号强度。
请参见图7，图7是本发明实施例提供的一种预测小区信号强度的方法流程示意图，用于在合适的时机预测该服务小区的邻区的信号强度，其中，步骤S214的详细描述如下。
步骤S214：所述用户设备判断所述服务小区的邻区的信号强度是否大于 第二阈值；若所述服务小区的邻区的信号强度大于所述第二阈值则执行上述步骤S209。
其中，在步骤S208之后，步骤S209之前，用户设备可以执行步骤S214。
具体地，当执行了步骤S208，即启动了对该服务小区的邻区的信号强度的测量之后，判断测量到的该服务小区的邻区的信号强度是否大于第二阈值，如果大于，则用户设备记录该服务小区的邻区在第一预设时间段的信号强度；如果小于，则不记录该服务小区的邻区在第一预设时间段的信号强度。
需要说明的是，该第二阈值可以为预先配置在该用户设备中的一个表征信号强度大小的参考值，或者由基站发送给该用户设备的一个表征信号强度大小的参考值。当该第二阈值由该基站发送给该用户设备时，该第二阈值的大小可以与上述事件A4中的绝对阈值(threshold)相等。
通过执行步骤S214，用户设备在服务小区的邻区的信号强度强到大于第二阈值时才开始记录该服务小区的邻区的信号强度，而无需记录任意时刻的该服务小区的邻区的信号强度，极大地减小了该用户设备的存储压力和运算压力。
为了进一步地完善本发明实施例的方案，还可以执行步骤S201～S214，以实现对服务小区和该服务小区的邻区的信号强度进行预测和上报，对应的流程图如图7A所示。各个步骤的详细描述可以对应参照上述相同步骤的描述，此处不再赘述。
实施例二：
请参见图8，图8是本发明实施例提供的一种上报小区信号强度的方法流程示意图。该方法包括：
步骤S801：用户设备接收测量配置，对所述小区进行信号强度的测量。
其中，该小区可以是服务小区，也可以是服务小区的邻区，还可以是服务小区和该服务小区的邻区。
具体的，请参阅对步骤S201的描述，此处不再详述。
步骤S802：所述用户设备根据第一预设时间段内的最后一个预设时间点的测量值，判断是否满足上报条件。
具体地，该第一预设时间段为预先设置的一个时间段，在该第一预设时间段内存在多个预设时间点，其中，每个预设时间点均为测量信号强度的时间点，每一次测量都会得到一个测量值。
举例来说，假设预先设置的第一预设时间段为5秒，起始时间点为第3000秒，且该5秒内每隔1秒进行一次信号强度的测量，那么该5秒中的第3000秒、第3001秒、第3002秒、第3003秒、第3004秒和第3005秒均为预设时间点，其中，第3005秒为该第一预设时间段内的最后一个预设时间点。
进一步地，该上报条件具体为上述上报测量报告的条件，该测量报告可以指示用户设备以事件A1、A2、A3、A4、A5、A6、B1和B2中至少一项作为判断是否上报测量报告的条件，用户设备以事件A1、A2、A3、A4、A5、A6、B1和B2中至少一项作为判断条件时，均涉及到与测量到的小区的信号强度的测量值进行对比。
举例来说，当测量报告指示用户设备以事件A5(即服务小区的信号强度比绝对阈值1低且邻区的信号强度比绝对阈值2高)为判断是否上报测量报告的条件时，用户设备判断服务小区的信号强度是否比绝对阈值1低且邻区的信号强度是否比绝对阈值2高，如果判断结果均为是，则表明满足上报条件，即上报A5对应的测量报告的条件。在判断的过程中，是将测量到的服务小区的信号强度的测量值与绝对阈值1比较，将测量到的服务小区的邻区的信号强度的测量值与绝对阈值2比较。另外，当测量报告指示用户设备以A1、A2、A3、A4、A6、B1和B2中至少一项作为判断是否上报测量报告的条件时，判断的原理与上述A5的判断原理相同，此处不一一举例。
步骤S803：若所述测量值满足上报条件，所述用户设备判断是否存在预测值。
具体地，如果存在预测值，则该预测值是用户设备计算出的一段时间后该小区的信号强度，举例来说，假设用户设备在第3000秒、第3001秒、第3002秒、第3003秒、第3004秒和第3005秒均对该小区进行了信号强度的测量，其中，第3005秒测量到的信号强度为-90db，用户设备又基于第3000秒、第3001秒、第3002秒、第3003秒、第3004秒和第3005秒的信号强度计算出第3008秒的信号强度为-95db；那么在第3005秒来看，上述-90db为测量值， 上述-95db为预测值(第3008秒的预测值)。
进一步地，预测值的计算是在用户设备接收测量配置，对所述小区进行信号强度的测量之后进行的，计算的方式可以是：在所述第一预设时间段内，记录所述小区的信号强度的测量值；基于在所述第一预设时间段内的所述小区的信号强度的测量值，所述用户设备分析出所述小区的信号强度的变化趋势；根据所述变化趋势，所述用户设备预测在第二预设时间的所述小区的信号强度的预测值。
在一种可选的方案中，上述变化趋势为下降趋势，该下降趋势可以是指：在该第一预设时间段内，第一预设时间段的起始时间点的信号强度与结束时间点的信号强度值的差值大于预先设定的第一下降阈值，且在第一预设时间段内的多个时间点中的某个时间点的信号强度比该某个时间点的前一个时间点的信号强度大时，该某个时间点的信号强度值与该某个时间点的前一个时间点的信号强度值的差值不超过预先设定的第一上升阈值。
举例来说，假设预先设定的第一下降阈值为10db，第一上升阈值为6db，并且以用户设备中计时器记录的第3000秒为起始记录点的5秒内，记录的第3000秒的信号强度为-83db，第3001秒的信号强度为-86db，第3002秒的信号强度为-89db，第3003秒的信号强度为-92db，第3004秒的信号强度为-91db，第3005秒的信号强度为-94db。由以上数据可以得到，在该5秒内，信号强度的下降的幅度为第3000秒的-86db减去第3005秒的-94db，-83db减去-96db等于11db，大于第一下降阈值10db；第3004秒的信号强度比第3003秒的信号强度大，大过的幅度为-91db减去-92db等于1db，小于第一上升阈值6db，因此可以确定小区的信号强度呈下降趋势。
在又一种可选的方案中，上述变化趋势为上升趋势，该上升趋势具体是指：在该第一预设时间段内，第一预设时间段的结束时间点的信号强度与起始时间点的信号强度的差值大于预先设定的第二上升阈值，且在第一预设时间段内的多个时间点中的某个时间点的信号强度比该某个时间点的前一个时间点的信号强度小时，该某个时间点的前一个时间点的信号强度与该某个时间点的信号强度的差值不超过预先设定的第二下降阈值。
举例来说，假设预先设定的第二上升阈值为10db，第二下降阈值为6db， 并且以用户设备中计时器记录的第3000秒为起始记录点的5秒内，记录的第3000秒的信号强度为-94db，第3001秒的信号强度为-91db，第3002秒的信号强度为-92db，第3003秒的信号强度为-89db，第3004秒的信号强度为-86db，第3005秒的信号强度为-83db。由以上数据可以得到，在该5秒内，信号强度的上升幅度为第3005秒的-83db减去第3000秒的-94db，-83db减去-94db等于11db，大于第二上升阈值10db；第3002秒的信号强度比第3001秒的信号强度小，小于的幅度为-91db减去-92db等于1db，小于第二下降阈值6db，因此可以确定小区的信号强度呈上升趋势。
进一步地，以下以上述变化趋势为下降趋势为例，来阐述如何根据信号强度的变化趋势预测未来某个时间点的信号强度。
当判断出该小区的信号强度呈下降趋势时，进一步根据记录的多个时间点的信号强度来确定该下降趋势的大致下降规律，进而根据该下降规律预测出小区在第二预设时间的信号强度。
在一种可选方案中，该小区的信号强度的下降幅度与下降所持续的时间近似成比例关系，例如，假设第一预设时间段为5秒，其中，第0、1、2、3、4、5秒记录的信号强度分别为：-83db、-86db、-89db、-92db、-91db、-94db，那么记录开始时的信号强度减去记录结束时的信号强度，然后除以记录所持续的时间得到的数据为：((-83)-(-94))/5＝2.2db，即小区的信号强度每隔1秒大约下降2.2db。小区的信号强度呈下降趋势时，可以认为小区在随后的一段时间里信号强度会按照该下降趋势持续下降。因此可以根据该下降趋势大致推算出第二预设时间点的信号强度。
上述第二预设时间是记录完上述第一预设时间段的信号强度之后的一个时间点，可以根据预先定义的规则推导得到，例如，记录完上述第一预设时间段的信号强度，再间隔预设时间(如3秒)后的时间为上述第二预设时间。如果开始记录该小区的信号强度的时间为用户设备中的计时器记录的第3000秒，用户设备共记录了5秒内的信号强度，那么3000+5+3＝3008秒，即第3008秒为上述第二预设时间；如果后续用户设备又在第4000秒开始记录5秒内的信号强度，那么4000+5+3＝4008秒，即第4008秒为上述第二预设时间，依次类推。也即是说，用户设备每次记录第一预设时间段的信号强度后，都会根据 记录时的时间以及预先设置的一个间隔时间来推导出一个第二预设时间。
如果记录结束后间隔3秒的时间为上述第二预设时间，那么可以推导出该第二预设时间的信号强度为：记录的最后一个信号强度减去估计的每秒信号强度下降值乘以间隔时间。以上述为例，(-94)-2.2*3＝-100.6db。
需要说明的是，小区的信号强度的下降幅度与下降所持续的时间还可能成其他的线性关系，具体为哪种线性关系可以对已经记录的信号强度进行数学建模得到。
进一步地，在用户设备接收测量配置，对小区进行信号强度的测量之后，在第一预设时间段内，用户设备记录小区的信号强度的测量值之前，还可以判断在第一预设时间段之前测量到的测量值是否满足预设条件，当该测量值满足预设条件时，用户设备才执行在第一预设时间段内，记录小区的信号强度的测量值的步骤。在一种可选的方案中，该预设条件为信号强度高于阈值；在又一种可选的方案中，该预设条件为信号强度低于阈值。需要说明的是，该阈值可以为预先存储在该用户设备中的用于参考对比的信号强度值，也可以为基站向该用户设备发送的测量配置中包含的对比阈值；该阈值可以与事件A2或者事件A4对应的绝对阈值(threshold)相等，也可以根据实际情况设置为其他值。
举例来说，假设该预设条件为低于-90db；用户设备在第2999秒测量到的信号强度的测量值为-91db，用户设备将该-91db与-90db比较得出第2999秒的信号强度的测量值满足该预设条件，那么用户设备记录第2999秒后的第一预设时间段内的信号强度的测量值。进一步地，如果用户设备在第2999秒测量到的信号强度为-80db，用户设备将该-80db与-90db比较得出第2999秒的信号强度的测量值不满足该预设条件，那么用户设备暂不记录信号强度的测量值。
步骤S804：若存在所述预测值，所述用户设备上报所述预测值。
具体地，当判断出存在预测值时，用户设备向该基站上报测量报告时，该测量报告中的信号强度为该预测值而非测量值。
通过执行步骤S801～S804，当小区的信号强度满足上报条件时，先判断是否存在预测值，若存在预测值则上报该预测值，使基站能够根据该预测值提前进行小区切换，保证了网络连接的连续性。
