小区测量的方法、测量装置、终端设备、芯片及存储介质
本申请要求在2019年11月30日提交中国国家知识产权局、申请号为201911208726.3的中国专利申请的优先权，发明名称为“小区测量的方法、测量装置、终端设备、芯片及存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及移动通信技术领域，尤其是涉及一种小区测量的方法、测量装置、终端设备、芯片及存储介质。
背景技术
在现有技术中，终端设备从满足异频起测条件开始进行异频异系统邻小区测量，直到发生小区重选，往往会需要一段时间，在这段时间上的持续测量，绝大部分是没有必要的。终端设备从掉网到再次搜索到网络，往往会持续一定时间，终端设备在无网络覆盖的区域内执行的搜网是无谓的。可见，现有技术中的小区测量以及网络搜索会造成终端设备的功耗较大。
发明内容
本申请实施例提供了一种小区测量的方法、测量装置、终端设备、芯片及存储介质，以解决现有技术中存在的小区测量以及网络搜索造成终端设备的功耗较大的问题。
有鉴于此，本申请第一方面提供一种小区测量的方法，可以包括：当终端设备驻留在第一小区时，如果终端设备确定处于目标环境，则终端设备可以获取终端设备驻留的第一小区的信号强度。这里的目标环境为终端设备提前识别出来的固定场所或者固定路线。然后，若获取到的信号强度低于第一门限并且高于第二门限，则终端设备执行第二小区测量，第二小区是终端设备根据所述目标环境确定的小区；若获取到的信号强度低于第二门限，则终端设备执行第三小区测量，第三小区包括第一小区的邻小区。因为本申请可以预先学习到目标环境对应的小区。这样如果终端设备处于目标环境中，且当前驻留的小区的信号强度低于第一门限并且高于第二门限时，那么可以根据学习到的小区进行小区测量。从而可以有效避免无效测量，减少了终端设备的功耗。另外，当第二小区不满足条件时，终端设备可以对第三小区进行搜索，以扩大搜索的范围。
可选的，在本申请的一些实施例中，终端设备包括第一处理器和第二处理器。可以理解的是，第一处理器用于生成目标测量策略，第二处理器用于执行目标测量策略。终端设备的第一处理器将目标测量策略发送给终端设备的第二处理器。其中，目标测量策略包括第一门限、第二门限以及至少一个第二小区对应的小区 信息中的至少一项，第二门限小于第一门限，第二小区对应的小区信息包括第二小区对应的频率和第二小区对应的小区标识中的至少一项。这样，第二处理器可以根据目标测量策略中包括的信息执行小区测量，因为目标测量策略是终端设备预先学习到的目标环境对应的测量策略，所以可以有效避免无效测量，减少了终端设备的功耗。

可选的，在本申请的一些实施例中，当目标环境为固定场所，终端设备在指定时间段收集信息，并将收集到的信息作为描述信息；其中，指定时间段与固定场所存在对应关系。这样，由于用户在固定场所中通常在某一时间段驻留，所以可以通过采集该这个时间段的信息准确地得到固定场所的描述信息。

可以理解的是，终端设备预先在应用程序框架层或者调制解调器中存储预设选网策略(即相当于本申请中的预设测量策略或者预设搜网策略)。其中，如果预设选网策略存储在应用程序框架层，则由于在调制解调器中设置有与RIL匹配的适配器(图3中未画出)，所以通过调制解调器中的适配器与RIL之间的通信，可以将应用程序框架层中的预设选网策略传输至NAS。这样，本申请可以在NAS中执行目标选网策略(即相当于本申请中的目标测量策略或者目标搜网策略)的获取过程，并在获取到目标选网策略后，在RRC中根据目标选网策略进行选网处理(即相当于本申请中的小区测量或者网络搜索)。
在现有技术中，终端设备的功耗包括应用处理器以及调制解调器产生的功耗。其中，调制解调器功耗主要体现在待机功耗与数据业务功耗。对于待机功耗与数据业务功耗，可以由网络搜索和小区测量等因素造成。
现有技术中的搜网可以包括多种情况：例如，终端设备可以周期性地获取终端设备驻留的当前小区的信号电平值或信号质量值，若根据获取到的信号电平值或信号质量值，确定终端设备满足异频起测条件，则对异频邻小区、异系统邻小区进行测量。又如，终端设备在掉网的情况下，会持续轮番搜索网络。再如，如果终端设备当前驻留的网络不是终端设备所支持的最高制式网络，则会持续搜索最高制式网络。例如，终端设备支持的最高制式网络是4G，如果该终端设备当前驻留的网络是3G网络，则该终端设备会持续搜索4G网络。其中，上述的异频起测条件可以为Srxlev<＝SnonIntraSearchP，或者，Squal<＝SnonIntraSearchQ。其中Srxlev表示获取到的信号电平值，Squal表示获取到的信号质量值，SnonIntraSearchP表示异频、异系统测量的电平门限，SnonIntraSearchQ表示异频、异系统测量的质量门限，其中，涉及的各项参数的定义与3GPP TS36.304标准定义相同。
上述现有技术中的搜网都存在问题：从终端设备满足异频起测条件的时刻开始对异频邻小区、异系统邻小区进行测量，直至进行小区重选，往往需要一段时间，在这一段时间的持续测量，绝大部分是没有必要的测量，所以造成了系统资源的浪费，使得终端设备的功耗较大。另外终端设备掉网到再次搜索到网络，在这段时间内可能处于无网络覆盖的区域，此时持续轮番搜网会造成系统资源的浪费，以及浪费大量的功耗，也无法连接上网络，所以没有意义。此外，一些区域可能只有3G网络覆盖，而没有4G网络覆盖。当终端设备处于这些区域内，终端设备持续搜索4G网络只会浪费大量功耗，没有意义。
本申请基于对固定线路或者固定场所的无线网络信号特征进行学习、识别和预测，进而进行终端搜网、小区测量等方面的优化，从而节省终端功耗。
本申请实施例提供了多种不同的实施方案，以下分别进行阐述。
【小区测量的技术方案】
图4示出了本申请实施例中的一种小区测量方法的流程示意图。该方法应用于终端设备。在一些实施例中，用户可以通过图10B、图10D或者图10E所示的方式启动智能选网功能，然后终端设备执行本申请中小区测量的方法。在另一些实施例中，终端设备也可以自动执行本申请实施例所示的小区测量的方法。在另一些实施例中，当终端设备检测到网络信号质量较差，可以提示用户是否执行本申请实施例所示的小区测量方法。本申请实施例对小区测量的启动方式不做限定。
终端设备在和接入网设备正常连接的时候，会选择一个小区驻留。下面以终端设备驻留在第一小区为例进行说明。
如图4所示，本申请实施例中的小区测量方法可以包括以下步骤：
401、终端设备确定处于目标环境。
启用本申请实施例提供的小区测量方案后，终端设备会确定当前是否处于目标环境中。
目标环境是终端设备提前识别出来的固定场所或者固定路线。固定场所或者固定路线与用户的行为有关。例如，固定场所为用户经常活动的场所，如家、办公室等；固定路线为用户经常走的路线，如用户上下班经过的路线。
在一些实施例中，目标环境可以是终端设备通过收集的描述信息识别出来的。例如，终端设备可以获取应用程序中关于固定场所或者固定路线的信息。
终端设备确定目标环境的方式有很多种。
在一些实施例中，终端设备可以假设在一个时间段内，用户处于固定场所中。例如，可以假设晚上8点到早上6点，用户处于家中；又如，可以假设早上9点到早上12点，用户处于办公室中。
在另一些实施例中，终端设备可以假设离开固定场所时，认为用户处于固定路线中。例如，可以假设终端设备离开家的时候，用户处于家和办公室之间的路线中。
在另一些实施例中，终端设备可以假设在特定时间内离开固定场所，用户处 于固定路线中。例如，可以假设终端设备在早上7点至早上8点离开家的时候，用户处于家和办公室之间的路线中。
在另一些实施例中，终端设备可以获取第一信息，然后判断第一信息与第二信息是否匹配，如果匹配的话，可以确定终端设备处于目标环境。
第一信息可以是终端设备当前所处环境的信息。在一些实施例中，第一信息可以是终端设备当前驻留的小区的小区信息。在另一些实施例中，第一信息可以是终端设备当前连接的WiFi名称(也可以称为服务集标识(service set identifier，SSID))。本申请实施例对第一信息的具体内容不做限定。
可以理解的是，第二信息为目标环境的描述信息；其中，目标环境的描述信息可以包括小区的描述信息和无线保真(wireless fidelity，WiFi)的描述信息中的至少一种。
应理解，上述目标环境的描述信息为终端设备根据目标环境确定的，该描述信息的收集方式可以参考后续实施例，此处不赘述。
进一步地，小区的描述信息可以包括一个或多个小区的描述信息。
需要说明的是，小区的描述信息可以包括但不限于服务小区的标识(也可以称为移动网络小区信号指纹)、服务小区的信号强度、服务小区的邻小区的标识以及邻小区的信号强度中的一种或多种。
WiFi的描述信息可以包括一个或多个WiFi的描述信息。
需要说明的是，WiFi的描述信息可以包括但不限于WiFi名称，WiFi的信号强度中的一种或多种。其中，WiFi名称可以包括终端设备连接的WiFi的名称以及终端设备连接至WiFi时可扫描到的其他WiFi的名称中的至少一个；WiFi的信号强度可以包括WiFi的信号强度以及其他WiFi的信号强度中的至少一个。
示例性的，如果终端设备获取到的第一信息是信号强度、标识和名称中的至少一种，那么，可以判断其对应与第二信息中包括的信号强度、标识和名称中的至少一种是否匹配，如果存在至少一种匹配，可以确定终端设备处于目标环境。至少一种匹配可以包括：信号强度匹配，或者，标识匹配，或者，名称匹配，或者，信号强度和标识都匹配，或者，标识和名称都匹配，或者，信号强度和名称匹配，或者，信号强度、标识或者名称都匹配。
如果终端设备获取到的第一信息是信号强度，终端设备可以判断该信号强度与第二信息中包括的信号强度是否接近，若接近，可以认为信号强度匹配。
如果终端设备获取到的第一信息是标识，终端设备可以判断该标识是否与第二信息中包括的标识相同，若相同，可以认为标识匹配。
如果终端设备获取到的第一信息是名称，终端设备可以判断该名称是否与第二信息中包括的名称相同，若相同，可以认为名称匹配。
402、终端设备获取终端设备驻留的第一小区的信号强度。
当终端设备确定处于目标环境时，终端设备可以获取当前驻留的第一小区的信号强度。
在本申请实施例中，信号强度可以包括：参考信号接收功率(reference  signal receiving power，RSRP)。
当然，本申请中的信号强度还可以为信号质量值，相应地，后续中涉及的门限可以为信号质量值对应的门限值。其中，信号质量值可以包括如下参数：信号与干扰加噪声比(signal to interference plus noise ratio，SINR)、参考信号接收功率(reference signal receiving power，RSRP)、参考信号接收质量(reference signal receiving quality，RSRQ)或者接收的信号强度(received signal strength indication，RSSI)等。
403、当第一小区的信号强度低于第一门限时，终端设备执行第二小区测量。
若终端设备获取的第一小区的信号强度低于第一门限时，终端设备可以执行第二小区测量。
第二小区是终端设备预先根据目标环境的网络信号特征进行学习，识别确定的小区。
在一些实施例中，第一门限以及至少一个第二小区对应的小区信息，可以是从目标测量策略中获取。其中，目标测量策略可以由第一处理器生成，再发送给第二处理器，第二处理器用于执行目标测量策略。第一处理器和第二处理器可以是同一处理器，也可以是不同的处理器。
可以理解的是，第二小区对应的小区信息包括第二小区对应的频率和第二小区对应的小区标识中的至少一项。
进一步地，目标测量策略中还可以包括：至少一个第二小区对应的测量优先级。
示例性的，该目标测量策略中的第二小区包括小区1、小区2以及小区3的测量优先级。例如，小区1、小区2以及小区3的测量优先级从高到低，那么，在后续小区测量的过程中，可以先对小区1进行测量，再对小区2进行测量，最后对小区3进行测量。
在一些可选的实施例中，在步骤403之后，本申请实施例还可以包括：当第二小区的测量结果满足小区切换条件，终端设备驻留的小区由第一小区切换到第二小区。
可以理解的是，本申请中的切换可以包括重选和切换。其中，如果终端设备进行切换，则终端设备还需要给网络上报测量报告。
可选的，在执行步骤402之后，还可以执行步骤404：
404、当第一小区的信号强度低于第一门限并且高于第二门限时，终端设备执行第二小区测量。
终端设备在第一小区的信号强度低于第一门限的时候，可以进一步判断第一小区的信号强度是否高于第二门限，若高于，则终端设备可以执行第二小区测量。
第二小区是从现有标准中规定需要测量的小区中挑出来的小区。
步骤403以及步骤404中的小区测量的具体内容可以参考后续图5或图6所示实施例，此处不再赘述。
可选的，在执行步骤402之后，还可以执行步骤405：
405、当第一小区的信号强度低于第二门限时，终端设备执行第三小区测量。
终端设备在第一小区的信号强度低于第一门限的时候，可以进一步判断第一小区的信号强度是否低于第二门限，若低于，则终端设备可以执行第三小区测量。
在一些实施例中，第三小区是当前驻留小区的所有邻小区，也就是说，第三小区为现有标准中规定需要测量的小区。在另一些实施例中，第三小区是当前驻留小区的所有邻小区中，除第二小区外的所有邻小区。这种方式的好处在于，当第二小区不满足小区切换条件时，终端设备可以扩大搜索的范围。
可以理解的是，第一门限、第二门限以及至少一个第二小区对应的小区信息，同样可以是从目标测量策略中获取。该目标测量策略的具体内容可以参考图5或图6中所示实施例，此处不再赘述。
在另一些实施例中，本申请实施例还可以包括：当第二小区的测量结果满足小区切换条件，终端设备驻留的小区由第一小区切换到第二小区；当第三小区的测量结果满足小区切换条件，终端设备驻留的小区由第一小区切换到第三小区。
通过上述所述的实施例，本申请可以预先学习到目标环境对应的小区。这样如果终端设备处于目标环境中，且当前驻留的小区的信号强度低于第一门限时，那么可以根据学习到的小区进行小区测量。可以有效避免无效测量，减少了终端设备的功耗。
【收集描述信息的技术方案】
在一些实施例中，用户可以通过图10B、图10D或者图10E所示的方式来启动智能选网功能，然后终端设备执行本申请中收集描述信息的过程。在另一些实施例中，终端设备可以自动收集描述信息。
在一些实施例中，终端设备可以假设一个时间段内，用户处于固定场所中，所以终端设备可以收集这个时间段内的描述信息。示例性的，可以假设用户在早上2点至早上7点之间在家中。这样终端设备可以在这个时间段内收集描述信息。
当然，本申请还可以在连续多天的这个时间段内，用户处于固定场所中，终端设备收集描述信息。例如，连续周一至周五在这个时间段内收集描述信息。
在另一些实施例中，当用户离开一个固定场所时，可以开始收集描述信息，直到终端设备确定进入到另一个固定场所。示例性的，假设用户在离开家时，可以开始收集描述信息，直到终端设备确定进入到办公室，停止收集描述信息。该描述信息为关于家和办公室之间路线的描述信息。
在另一些实施例中，当用户离开一个固定场所时，可以开始收集描述信息，如果终端设备在一定时长内确定进入到另一个固定场所，那么在这个时长内收集的描述信息为可靠的描述信息，可以用来描述两个固定场所之间的路线。如果终端设备在一定时长内确定未进入到另一个固定场所，那么停止收集描述信息，且在这个时长内收集的描述信息不是可靠的描述信息，不能用来描述两个固定场所之间的路线。
示例性的，假设用户在离开家时，可以开始收集描述信息，如果终端设备在 50分钟内确定进入办公室，则在这50分钟收集到的描述信息为可靠的描述信息，可以用来描述家和办公室之间的路线。
在另一些实施例中，当用户在特定时间段内离开一个固定场所时，终端设备可以开始收集描述信息。例如，如果用户在早上7点至早上8点之间离开家的话，终端设备就认为用户处于家和办公室之间的固定路线上，然后在用户离开家时，开始收集描述信息。
在另一些实施例中，终端设备可以假设一个时间段内，用户处于固定路线中，所以终端设备可以收集这个时间段内的描述信息。例如，终端设备可以认为早上8点至早上10点，用户处于固定路线中，所以可以收集早上8点至早上10点之间的描述信息。上述收集描述信息的方式只是示例性说明，本申请对描述信息的收集方式不做限定。
在上述收集描述信息的实施例中，所收集的描述信息对应与固定场所或者固定路线关联。
例如，假设固定场所为家，终端设备在一定时间段内收集到小区的描述信息、WiFi的描述信息，并与家关联。示例性的，终端设备可以持续性收集几天的描述信息，从中选出强相关的描述信息，以WiFi名称为例进行说明。假设终端设备连续几天在这个时间段都能检测到WiFi名称为“我的家”，可以把这个名称与家关联起来。当终端设备再次检测到“我的家”，可以确定终端设备当前处于家这个固定场所。
需要说明的是，由于在收集描述信息的过程中，可能会收集到重复信息，比如，可能收集到同一小区的标识，或者同一WiFi的名称，这个时候，可以保留单份的信息，去除重复的信息，从而避免信息存在冗余。例如收集到两次同一WiFi的名称，可以只保留其中一次WiFi名称。
其中，收集的描述信息可以包括：小区的描述信息和WiFi的描述信息中的至少一种。小区的描述信息可以为终端设备驻留的服务小区的标识，服务小区的信号强度，服务小区的邻小区的标识以及邻小区的信号强度中的一种或多种。WiFi的描述信息可以为终端设备连接的WiFi名称、终端设备连接的WiFi信号强度、连接至WiFi时可扫描到的其他WiFi的名称，以及其他WiFi信号强度中的一种或多种。
通过上述所述的实施例，本申请可以预先收集到固定场所或者固定路线中的至少一个对应的描述信息，从而可以基于收集到的描述信息准确地识别终端设备是否处于固定场所或者固定路线中。
【小区测量的技术方案】
在一些实施例中，用户可以通过图10B、图10D或者图10E所示的方式启动智能选网功能，然后终端设备执行本申请中小区测量的方法。在另一些实施例中，终端设备也可以自动执行本申请实施例所示的小区测量的方法。在另一些实施例中，当终端设备检测到网络信号质量较差，可以提示用户是否执行本申请实施例 所示的小区测量方法。
如图5所示，为本申请实施例小区测量的方法的流程示意图。所述方法应用于终端设备，可以包括以下步骤：
501、检测终端设备处于固定场所还是固定路线。
可以理解的是，固定场所或者固定路线与用户的行为有关。例如，固定场所为用户经常活动的场所，如家、办公室等；固定路线为用户经常走的路线，如用户上下班经过的路线。检测的具体方法可以参考步骤401，此处不再赘述。
502、当终端设备处于固定场所时，从预设测量策略中获取目标测量策略。
在一种可选的方案中，终端设备根据该固定场所以及终端设备当前驻留的第一小区，从预设测量策略中获取目标测量策略。
目标测量策略可以由第一处理器生成，再发送给第二处理器，第二处理器用于执行目标测量策略。第一处理器和第二处理器可以是同一处理器，也可以是不同的处理器。
其中，目标测量策略中包括多个需要测量的小区对应的预设触发条件。可以理解的是，多个需要测量的小区相当于本申请中的至少一个第二小区。
进一步地，目标测量策略中还可以包括多个需要测量的小区对应的小区信息中的至少一项；多个需要测量的小区对应的小区信息包括多个需要测量的小区对应的频率和多个需要测量的小区对应的小区标识中的至少一项。当然，目标测量策略中还可以包括多个需要测量的小区的测量优先级、测量间隔以及网络制式中的至少一种。
503、判断多个需要测量的小区中是否包括终端设备当前驻留的第一小区。
在多个需要测量的小区中不包括第一小区的情况下，执行步骤504至步骤506；
在多个需要测量的小区中包括第一小区的情况下，执行步骤505和步骤506。
504、将第一小区切换至多个需要测量的小区中的一个小区。
可以理解的是，本申请可以直接对多个需要测量的小区进行小区测量，以便切换至满足小区切换条件的一个小区。或者，本申请可以采用网络配置的起测门限值判断是否需要进行小区测量，若需要进行小区测量，那么对多个需要测量的小区进行小区测量，以便切换至满足小区切换条件的一个小区。
505、获取终端设备当前驻留的第一小区的信号强度。
在本申请实施例中，信号强度可以包括如下参数：参考信号接收功率。当然，本申请中的信号强度还可以为信号质量值，相应地，后续中涉及的门限可以为信号质量值对应的门限值。其中，信号质量值可以包括如下参数：信号与干扰加噪声比、参考信号接收功率、参考信号接收质量或者接收的信号强度等。
506、判断第一小区的信号强度是否满足预设触发条件。
其中，预设触发条件可以包括但不限于以下所示条件：
(1)该预设触发条件包括：信号强度小于等于第一门限。
(2)在该目标测量策略中包括多个需要测量的小区的测量优先级的情况下， 预设触发条件包括：当前小区不属于目标测量策略中最高测量优先级对应的小区，以及，信号强度小于等于第一门限。
(3)预设触发条件包括：信号强度小于等于第一门限，以及信号强度大于等于第二门限；第一门限大于第二门限。
第一门限、第二门限是根据经验值进行设定的，可以根据用户的实际需求进行调整，本申请实施例中不做具体限定。
在第一小区的信号强度满足预设触发条件的情况下，执行步骤507。
在第一小区的信号强度不满足预设触发条件的情况下，执行第三小区测量。在一些实施例中，第三小区是当前驻留小区的所有邻小区，也就是说，第三小区为现有标准中规定需要测量的小区。在另一些实施例中，第三小区是当前驻留小区的所有邻小区中，除第二小区外的所有邻小区。这种方式的好处在于，当第二小区不满足小区切换条件时，终端设备可以扩大搜索的范围。
507、根据多个需要测量的小区的小区信息，进行小区测量得到测量结果。
在本申请实施例中，预先获取多个需要测量的小区的方式可以有很多种。
在一种实施例中，多个需要测量的小区可以是：终端设备在处于固定场所时驻留时长较长或者驻留次数较多的小区，或者服务质量较好的小区。
在另一种实施例中，多个需要测量的小区可以是：终端设备在处于固定场所时驻留时长较长的前N个小区，或者，驻留次数较多的前N个小区。N可以为预先设置的数值。
如果小区信息包括小区标识，终端设备可以根据小区标识确定小区，然后对该小区进行小区测量得到测量结果。
如果小区信息包括频率，终端设备可以对该频率对应的小区进行小区测量得到测量结果。
如果小区信息包括小区标识和测量优先级，终端设备可以根据小区标识确定多个小区，然后可以按照测量优先级由高到低的顺序，对该多个小区进行小区测量得到测量结果。
如果小区信息包括小区标识和测量间隔，终端设备可以根据小区标识确定小区，然后按照测量间隔对该小区进行小区测量得到测量结果。
在现有技术中，假如终端设备未处于终端设备支持的最该网络制式，终端设备在对邻小区进行小区测量的过程中，会首先在最高网络制式下，进行小区测量。但是，若邻小区支持的网络制式不包括最高网络制式，则会造成终端设备的无效测量，使得终端设备的功耗较大。
而在本申请实施例中，终端设备检测到未处于终端设备支持的最高网络制式，且多个需要测量的小区不支持该最高网络制式，可以按照目标测量策略中的网络制式进行小区测量，该网络制式不为最高网络制式。这样，终端设备无需在终端设备支持的最高网络制式下进行小区测量，降低终端设备的功耗。
可选的，在步骤507之后，还可以执行步骤508。
508、当目标小区的测量结果满足小区切换条件时，将终端设备当前驻留的 第一小区切换至目标小区。
其中，目标小区为多个需要测量的小区中的一个小区。
可选的，为了更新目标测量策略，本申请还可以根据测量结果以及预先存储的历史数据的学习结果进行拟合，如果拟合结果的拟合程度较好，可以优化目标测量策略。应理解，在优化过程中可以调整目标测量策略中的一项或多项参数。如果拟合结果的拟合程度较差(如完全不拟合)，则将目标测量策略进行删除。
通过实施本申请实施例，本申请可以预先学习到固定场所对应的测量策略。这样如果终端设备处于固定场所中，且当前驻留的小区的信号强度满足预设触发条件时，那么可以根据学习到的目标测量策略进行小区测量。可以有效避免无效测量，减少了终端设备的功耗。
【小区测量的技术方案】
在一些实施例中，用户可以通过图10B、图10D或者图10E所示的方式启动智能选网功能，然后终端设备执行本申请中小区测量的方法。在另一些实施例中，终端设备也可以自动执行本申请实施例所示的小区测量的方法。在另一些实施例中，当终端设备检测到网络信号质量较差，可以提示用户是否执行本申请实施例所示的小区测量方法。
如图6所示，为本申请实施例小区测量方法的流程示意图。所述方法应用于终端设备，具体包括以下步骤：
601、检测终端设备处于固定场所还是固定路线。
具体内容可以参考步骤401，此处不再赘述。
602、当终端设备处于固定路线时，根据固定路线和终端设备当前驻留的第一小区，从预设测量策略中获取目标测量策略。
如果终端设备处于固定路线，那么终端设备可以根据该固定路线和当前驻留的第一小区，从预设测量策略中获取目标测量策略。
目标测量策略的具体内容可以参考步骤502，此处不再赘述。
603、判断多个需要测量的小区中是否包括终端设备当前驻留的第一小区。
在多个需要测量的小区中不包括第一小区的情况下，执行步骤604至步骤606；

(1)预设触发条件包括：信号强度小于等于第一门限。
(2)预设触发条件包括：信号强度小于等于第一门限，以及信号强度大于 等于第二门限；第一门限大于第二门限。
第一门限、第二门限是根据经验值进行设定的，可以根据用户的实际需求进行调整，本申请实施例中不做具体限定。
在第一小区的信号强度满足预设触发条件的情况下，执行步骤607；
在第一小区的信号强度不满足预设触发条件的情况下，执行第三小区测量。在一些实施例中，第三小区是当前驻留小区的所有邻小区，也就是说，第三小区为现有标准中规定需要测量的小区。在另一些实施例中，第三小区是当前驻留小区的所有邻小区中，除第二小区外的所有邻小区。这种方式的好处在于，当第二小区不满足小区切换条件时，终端设备可以扩大搜索的范围。
607、根据多个需要测量的小区的小区信息，进行小区测量得到测量结果。
具体过程可以参考步骤507，此处不再赘述。
可选的，在步骤607之后，还可以执行步骤608。

其中，目标小区为多个需要测量的小区中的一个小区。
可选的，为了更新目标测量策略，本申请还可以根据测量结果以及预先存储的历史数据的学习结果进行拟合，如果拟合结果的拟合程度较好，可以优化目标测量策略。应理解，在优化过程中可以调整目标测量策略中的一项或多项参数。如果拟合结果的拟合程度较差(如完全不拟合)，则将目标测量策略进行删除。
通过实施本申请实施例，本申请可以预先学习到固定路线对应的测量策略。这样如果终端设备处于固定路线上，且当前驻留的小区的信号强度满足预设触发条件时，那么可以根据学习到的目标测量策略进行小区测量。可以有效避免无效测量，减少了终端设备的功耗。
【 网络搜索的技术方案】
现有技术中，当终端设备处于无网络信号覆盖的情况下，依然会进行搜网。这种搜网会消耗大量的功耗，并且没有意义。通过本实施例的技术方案，可以预先学习到无网络区域的范围，当检测到终端设备进入该区域，可以停止搜网，从而节省功耗。
在一些实施例中，用户可以通过图10B、图10D或者图10E所示的方式启动智能选网功能，然后终端设备执行本申请中网络搜索的方法。在另一些实施例中，终端设备也可以自动执行本申请实施例所示的网络搜索的方法。在另一些实施例中，当终端设备检测到无网络信号，可以提示用户是否执行本申请实施例所示的网络搜索方法。
如图7所示，为本申请实施例中网络搜索的方法的一个实施例示意图，所述方法应用于终端设备，具体可以包括以下步骤：
701、检测终端设备处于固定场所还是固定路线。
在本申请实施例中，终端设备可以在无网络服务状态的情况下，检测终端设 备处于固定场所还是固定路线。其中，可以包括但不限于以下方式确定该终端设备是否处于无网络服务状态：
在一种可能的实现方式中，图3中所述的连接管理器在检测到终端设备的当前网络状态为无网络服务状态的情况下，向调制解调器发送第一状态消息，该第一状态消息用于指示该终端设备的当前网络状态为无网络服务状态。或，连接管理器在监测到终端设备的当前网络状态为有网络服务状态的情况下，向调制解调器发送第二状态消息，该第二状态消息用于指示该终端设备的当前网络状态为有网络服务状态。这样，调制解调器可以根据状态信息类型确定终端设备的当前网络状态。
在另一种可能的实现方式中，连接管理器在检测到终端设备的当前网络状态为无网络服务状态的情况下，向调制解调器发送状态消息。这样，在调制解调器接收到状态消息的情况下，确定该终端设备的当前网络状态为无网络服务状态，或，在调制解调器未接收到状态消息的情况下，确定该终端设备的当前网络状态为有网络服务状态。
示例性的，有网络服务状态可以为连接有移动数据的状态、连接有WiFi的状态、连接有以太网的状态或连接有蓝牙的状态等；无网络服务状态可以为无服务小区、限制服务、随机接入失败等状态，本申请实施例对网络服务状态的具体形式不做特殊限制。
可以理解的是，固定场所或者固定路线与用户的行为有关。例如，固定场所为用户经常活动的场所，如家、办公室等；固定路线为用户经常走的路线，如用户上下班经过的路线。检测的具体方法可以参考步骤401，此处不再赘述。
702、当终端设备处于固定场所时，从预设搜网策略中获取目标搜网策略。
在一种可选的方案中，终端设备根据该固定场所以及终端设备掉网前最后驻留的小区，从预设搜网策略中获取目标搜网策略。
目标搜网策略可以由第一处理器生成，再发送给第二处理器，第二处理器用于执行目标搜网策略。第一处理器和第二处理器可以是同一处理器，也可以是不同的处理器。
其中，目标搜网策略中可以包括多个需要搜索的小区对应的小区信息中的至少一项；多个需要搜索的小区对应的小区信息包括多个需要搜索的小区对应的频率和多个需要搜索的小区对应的小区标识中的至少一项。当然，目标搜网策略中还可以包括多个需要搜索的小区的搜索优先级、搜索间隔、触发搜网时长以及网络制式中的至少一种。
应理解，触发搜网时长用于确定搜网时刻；搜网时刻可以为根据检测到终端设备掉网的时刻与触发搜网时长确定的时刻，比如将检测到终端设备掉网的时刻与触发搜网时长进行相加得到该搜网时刻。
703、根据多个需要搜索的小区对应的小区信息，进行网络搜索得到搜索结果。
在本申请实施例中，预先获取多个需要搜索的小区的方式可以有很多种。
在一种实施例中，多个需要搜索的小区可以是：终端设备在处于固定场所时驻留时长较长或者驻留次数较多的小区，或者服务质量较好的小区，或者搜索成功次数较多的小区。
在另一种实施例中，多个需要搜索的小区可以是：终端设备在处于固定场所时驻留时长较长的前N个小区，或者，驻留次数较多的前N个小区，或者搜索成功次数较多的前N个小区。N可以为预先设置的数值。
如果小区信息包括小区标识，终端设备可以根据小区标识确定小区，然后对该小区进行小区搜索得到搜索结果。
如果小区信息包括频率，终端设备可以根据该频率进行小区搜索得到搜索结果。
如果小区信息包括小区标识和搜索优先级，终端设备可以根据小区标识确定多个小区，然后可以按照搜索优先级由高到低的顺序，对该多个小区进行小区搜索得到搜索结果。
如果小区信息包括小区标识以及触发搜网时长，终端设备可以根据小区标识确定小区，然后可以在搜网时刻开始对该小区进行小区搜索得到搜索结果。
如果小区信息包括小区标识和搜索间隔，终端设备可以根据小区标识确定小区，然后按照搜索间隔对该小区进行小区搜索得到搜索结果。
如果小区信息包括小区标识和搜索间隔以及触发搜网时长，终端设备在检测到终端设备掉网后，在历史频点上按照搜索间隔进行搜网操作，如果若干次搜索均未搜索成功，终止通过搜索间隔以及历史频点进行的搜网操作，并在搜网时刻时开始根据目标搜网策略进行网络搜索。或，如果若干次搜索的过程中存在任一次搜索成功，终端设备可以驻留至搜索到的服务小区中，这样由于在搜网时刻之前可以搜索到服务小区，因此，该目标搜网策略存在偏差。此时，本申请可以对该目标搜网策略进行更新。例如，可以将搜索成功使用的频率以及搜索到的服务小区的小区标识作为新的学习数据，这样，可以根据新的学习数据进行深度学习，更新该目标搜网策略。
可选地，在步骤703，还可以执行步骤704。
704、当根据搜索结果确定目标小区满足预设驻留条件时，将终端设备驻留至目标小区。
可选的，本申请还可以根据搜索结果，优化目标搜网策略。应理解，在优化过程中可以调整目标搜网策略中的一项或多项参数。
可选的，如果通过目标搜网策略多次没有搜索成功，则可以删除目标搜网策略。
通过本申请实施例，本申请可以预先学习到固定场所对应的搜网策略。这样如果终端设备处于固定场所中，并发生掉网，那么可以根据学习到的目标搜网策略进行网络搜索。可以有效避免无效搜网，减少了终端设备的功耗。

在一些实施例中，用户可以通过图10B、图10D或者图10E所示的方式启动智能选网功能，然后终端设备执行本申请中网络搜索的方法。在另一些实施例中，终端设备也可以自动执行本申请实施例所示的网络搜索的方法。在另一些实施例中，当终端设备检测到无网络信号，可以提示用户是否执行本申请实施例所示的网络搜索方法。
如图8所示，为本申请实施例中网络搜索的方法的一个实施例示意图，所述方法应用于终端设备，具体可以包括以下步骤：
801、检测终端设备处于固定场所还是固定路线。
具体内容可以参考步骤701，此处不再赘述。
802、当终端设备处于固定路线时，根据固定路线和终端设备掉网前最后驻留的小区，从预设搜网策略中获取目标搜网策略。

804、当根据搜索结果确定目标小区满足预设驻留条件时，将终端设备驻留至目标小区。
可选的，本申请还可以根据搜索结果，优化目标搜网策略。应理解，在优化过程中可以调整目标搜网策略中的一项或多项参数。
可选的，如果通过目标搜网策略多次没有搜索成功，则可以删除目标搜网策略。
通过本申请实施例，本申请可以预先学习到固定路线对应的搜网策略。这样如果终端设备处于固定路线中，并发生掉网，那么可以根据学习到的目标搜网策略进行网络搜索。可以有效避免无效搜网，减少了终端设备的功耗。
在上述图5、图6、图7和图8所示的实施例中，涉及到预设测量策略以及预设搜网策略，以及图4所示的实施例中涉及到目标测量策略，应理解，这个目标测量策略为某一个预设测量策略。所以可以通过本申请实施例预先学习到这些策略。为了便于描述，本申请将预设测量策略以及预设搜网策略统称为预设选网策略。
本申请中的策略生成方法可以应用于终端设备，该终端设备可以包括智能选网主控模块、调制解调器选网模块以及传感器处理器(sensor hub)，该智能选网主控模块包括环境感知单元和选网策略交互单元。可以理解的是，智能选网主控模块相当于本申请中的第一处理器，以及调制解调器选网模块相当于本申请中的第二处理器。预设选网策略可以由第一处理器生成，再发送给第二处理器，第二处理器用于执行预设选网策略。第一处理器和第二处理器可以是同一处理器，也可以是不同的处理器。
可以理解的是，本申请可以包括但不限于以下方式触发执行本申请实施例中的策略生成方法：
方式一、终端设备的主设置界面中包括智能选网功能。这样，终端设备在接收到智能选网功能的启动指令后，执行本申请中的策略生成方法的步骤。
示例性的，如图10A所示，终端设备的主设置界面中预先设置有不同功能对应的开关控件，所以可以根据开关控件对不同功能进行设置。例如，图10A中的飞行模式的开关控件设置为已关闭状态，蓝牙的开关控件设置为已开启状态，智能选网的开关控件设置为已关闭状态。
此时，如图10B所示，用户可以触发智能选网的开关控件，使得智能选网的开关控件从已关闭状态转换为已开启状态，从而终端设备的智能选网功能开启。
需要说明的是，该智能选网功能还可以设置在电池设置界面中。例如，如图10C所示，可以在省点模式下智能选网功能。并且在省点模式处于已开启状态的情况下，终端设备展示该智能选网的开关控件。这样，如图10D所示，用户可以触发智能选网的开关控件，使得智能选网的开关控件从已关闭状态转换为已开启状态，从而终端设备的智能选网功能开启。
方式二、终端设备在启动后自动执行本申请实施例中的策略生成方法。
方式三、终端设备检测到功耗较高时，执行本申请实施例中的策略生成方法。
方式四、终端设备检测到功耗较高时，展示提示框，以便用户确定是否开启智能选网功能。
示例性的，如图10E所示，由于终端设备的功耗较高，所以终端设备展示提示框，该提示框中包括文本信息“是否开启智能选网功能”、“是”按钮以及“否”按钮。这样，在用户触发“是”按钮的情况下，终端设备执行本申请实施例中的策略生成方法。
上述触发执行本申请实施例中的策略生成方法的方式只是示例性说明，本申请对此不做限定。在通过上述方式确定进行策略生成方法后，可以通过以下步骤进行策略生成：
901、环境感知单元获取指定时间段内不同时刻的描述信息、网络事件信息以及传感器信息。
其中，描述信息可以包括：终端设备连接的WiFi名称，终端设备驻留的服务小区的标识，服务小区的信号强度，服务小区的邻小区的标识以及邻小区的信号强度，终端设备连接的WiFi信号强度、连接至WiFi时可扫描到的其他WiFi的名称，以及其他WiFi信号强度中的至少一个。当然，描述信息还可以包括其他信息，比如还包括但不限于：服务小区对应的网络制式，服务小区对应的位置区(location area，LA)，服务小区对应的信号质量值以及非连续接收(discontinuous reception，DRX)周期，邻小区对应的网络制式以及邻小区对应的信号质量中的至少一个。应理解，邻小区可以为单个或多个小区。
可以理解的是，可以通过但不限于以下方式获取描述信息：
方式一、环境感知单元可以在指定时间段到达之前向调制解调器选网模块发 送第一信息获取指令；调制解调器选网模块根据第一信息获取指令，按照预设周期获取指定时间段内不同时刻的描述信息以及网络事件信息，并向环境感知单元发送描述信息以及网络事件信息。
方式二、调制解调器选网模块中预先存储有指定时间段，并在指定时间段到达时按照预设周期在指定时间段内获取不同时刻的描述信息以及网络事件信息，并向环境感知单元发送描述信息以及网络事件信息。如图9所示，本步骤可以包括步骤9011：调制解调器选网模块向环境感知单元发送描述信息以及网络事件信息。
可以理解的是，上述两种方式中，调制解调器选网模块可以在获取到指定时间段内各个时刻的描述信息以及网络事件信息后，向环境感知单元发送各个时刻的描述信息以及网络事件信息。或者，调制解调器选网模块可以在获取到指定时间段内某个时刻的描述信息以及网络事件信息后，向环境感知单元发送该某个时刻的描述信息以及网络事件信息。
应理解，事件信息包括终端设备当前的连接状态。示例地，该事件信息包括：有网络服务状态以及无网络服务状态。该有网络服务状态可以进一步划分为：空闲状态和连接状态，该无网络服务状态可以进一步划分为：无服务状态、限制服务状态以及随机接入失败状态(即基站没有空闲无线资源分配至终端设备)，上述示例只是举例说明，本申请对此不做特殊限制。
同样地，获取传感器信息的方式可以包括但不限于以下方式：
方式一、环境感知单元可以在指定时间段到达之前向传感器处理器发送第二信息获取指令；传感器处理器根据第二信息获取指令，按照预设周期获取不同时刻的传感器信息，并向环境感知单元发送传感器信息。
方式二、传感器处理器中预先存储有指定时间段，并在指定时间段到达时，按照预设周期获取不同时刻的传感器信息，并向环境感知单元发送传感器信息。
可以理解的是，上述两种方式中，传感器处理器可以在获取到各个时刻的传感器信息后，向环境感知单元发送各个时刻的传感器信息。或者，传感器处理器可以在获取到某个时刻的传感器信息后，向环境感知单元发送该某个时刻的传感器信息。如图9所示，本步骤可以包括步骤9011：传感器处理器向环境感知单元发送传感器信息。应理解，传感器信息可以包括本申请中的位置特征数据。
其中，该传感器信息可以为终端设备中内置的环境感知传感器采集到的数据，该环境感知传感器可以包括但不限以下至少一个：重力计传感器、加速度传感器以及陀螺仪传感器等。当然，本申请中的环境感知传感器还可以包括其他传感器，例如，还包括全球定位系统(Global Positioning System，GPS)传感器，那么可以通过GPS传感器获取到GPS定位点的信息。
应理解，该指定时间段可以为用户预先设置的时间段。示例性的，用户通常9：30-11：30之间在办公室上班，20：30-21：30之间在家休息，等等，因此，可以将该指定时间段设置为9：30-11：30以及20：30-21：30。
示例性的，在用户开启智能选网的开关控件后，终端设备展示该智能选网界 面。例如，如图11A所示，该智能选网界面用于设定时间段。该终端设备中已存储有指定时间段9：30-11：30。
此时，如图11B所示，用户可以触发“+”控件，以便添加新的指定时间段。
在用户触发“+”控件后，该终端设备的界面如图11C所示。此时，如果用户触发“从20:30”所在的矩形框，则可以在终端设备的显示屏展示的小时列表和分钟列表中确定指定时间段的起始时间。
若用户设置完成该指定时间段，则可以返回智能选网界面，如图11D所示，该设定时间段中包括原本存储的指定时间段9：30-11：30，以及新添加的指定时间段20：30-21：30。
上述设置指定时间段的方式只是示例性说明，本申请对此不做具体限定。
902、环境感知单元根据不同时刻的传感器信息，确定处于固定场所还是固定路线。
在一些实施例中，在固定场所和固定路线的位置特征存在差异，所以，可以通过传感器信息识别终端设备处于固定场所还是固定路线。例如，位置特征波动较大，用户在固定路线上；位置特征波动较小，用户在固定场所中。
在另一些实施例中，终端设备可以观测指定时间段内GPS传感器采集到的GPS定位点的信息，若采集到GPS定位点长时间处于未移动的状态，则可以确定终端设备处于固定场所中；相反，若采集到GPS定位点处于不断移动的状态，则可以确定终端设备处于固定路线中。
在另一些实施例中，本申请还可以根据不同时刻的描述信息确定终端设备处于固定路线还是固定场所。例如，假设描述信息包括终端设备驻留的当前小区的小区标识的情况下，如果终端设备在一个时间段内驻留的小区为同一小区，那么可以确定终端设备在这个时间段内所处的场所为固定场所。
又如，假设描述信息信息包括终端设备驻留的当前小区的小区标识的情况下，如果终端设备在该指定时间内驻留的小区种类较少，且在该指定时间内驻留各个小区的时长都比较长，那么可以确定该终端设备在该指定时间段内驻留在固定场所。如果终端设备在该指定时间内驻留的小区种类较多，且在该指定时间内驻留各个小区的时长都比较短，那么可以确定该终端设备在该指定时间段内驻留在固定路线。
又如，假设描述信息包括终端设备连接的当前WiFi的WiFi标识的情况下，如果终端设备在该指定时间段内连接的WiFi种类较少，且在该指定时间内连接各个WiFi的时长都比较长，那么可以确定该终端设备在该指定时间段内驻留在固定场所。如果终端设备在该指定时间内连接的WiFi种类较多，且在该指定时间内连接的WiFi的时长都比较短，则可以确定该终端设备在该指定时间段内驻留在固定路线。
在另一些实施例中，假设用户在终端的定位地图中预先设置有固定场所以及固定路线中的至少一种，那么终端设备可以读取定位地图的设置信息，且根据设置信息确定具体处于的固定场所或者具体处于的固定路线。
上述确定终端设备处于固定场所还是固定路线的方式只是示例性说明，本申请对此不做具体限制。
903、环境感知单元向存储器发送终端设备所处固定路线的路线标识或所处固定场所的场所标识中的一种、描述信息以及网络事件信息。
可以理解的是，该存储器中可以存储多组数据，并且每组数据都包含某一时刻对应的终端设备所处固定路线的路线标识或所处固定场所的场所标识中的一种、描述信息以及网络事件信息。
应理解，该存储器可以将每组数据关联至对应的固定场所或者固定路线。
904、选网策略交互单元从存储器中获取存储的多组数据，并根据多组数据生成预设选网策略，以及预设选网策略的策略触发条件。
可以理解的是，若本申请针对某一固定路线或者某一固定场所生成选网策略，则本步骤可以从存储器中获取与该某一固定路线或者某一固定场所关联的多组数据。
本申请对测量触发条件分情况进行说明：
情况一、当网络事件信息包括无网络服务状态时，该策略触发条件包括：终端设备处于固定路线或固定场所，确定终端设备掉网，以及终端设备掉网前最后驻留的小区与学习结果中预设搜网策略关联的掉网小区相同。
情况二、当终端设备处于有网络服务状态时，该策略触发条件包括：终端设备处于固定路线或固定场所，终端设备驻留的当前小区与学习结果中预设测量策略关联的小区相同。
需要说明的是，该预设选网策略的详细内容可以参考图4、图5、图6、图7以及图8中所述的目标测量策略以及目标搜网策略，此处不再赘述。
通过实施本申请实施例，可以预先针对固定场所和固定路线中的至少一种确定策略触发条件以及预设选网策略，以便终端设备在满足策略触发条件的情况下，可以根据预设选网策略进行选网处理。这样，通过预设选网策略进行选网处理，可以有效降低终端设备的损耗，提高了选网效率。
如图12所示，本申请实施例对选网方法进行概括性说明，在一些实施例中，用户可以通过图10B、图10D或者图10E所示的方式启动智能选网功能，然后终端设备执行本申请中选网方法。在另一些实施例中，终端设备也可以自动执行本申请实施例所示的选网方法。在另一些实施例中，当终端设备检测到网络信号质量较差，可以提示用户是否执行本申请实施例所示的选网方法。本申请实施例对选网的启动方式不做限定。
本申请中的选网方法可以应用于终端设备，所述方法可以用于图9中步骤904之后，包括以下步骤：
1201、环境感知单元获取最近一段时间段内，不同时刻的目标信息；目标信息包括传感器信息、描述信息以及网络事件信息。
在可选实施例中，若该终端设备处于有网络服务状态，则该最近一段时间段 的终止时刻与当前时刻相同；若终端设备处于无网络服务状态，则该最近一段时间段的终止时刻与检测到终端设备掉网的时刻相同。
在本申请实施例中，该传感器信息、描述信息以及网络事件信息的获取过程可以参考步骤901，此处不再赘述。
1202、环境感知单元在根据目标信息，确定终端设备处于固定路线或者固定场所时，向选网策略交互单元发送固定场所的场所标识或者固定路线的路线标识。
判断终端设备处于固定场所还是固定路线的方式有多种，比如可以参考步骤401中的方法检测终端设备处于固定场所还是固定路线，此处不再赘述。
1203、选网策略交互单元获取终端设备的当前小区信息和当前事件信息。
可以理解的是，当前事件信息的信息类型与步骤901中的网络事件信息的信息类型相同，本申请对此不再赘述。
应理解，在终端设备处于无网络服务状态的情况下，当前小区信息包括终端设备掉网前最后驻留的小区的小区信息；在终端设备处于有网络服务状态的情况下，当前小区信息包括终端设备驻留的当前小区的小区信息。其中，小区信息可以包括小区标识以及信号强度、信号质量值以及频率中的至少一个。
其中，获取终端设备的当前小区信息以及当前事件信息的方式可以参考步骤901，此处不再赘述。
1204、选网策略交互单元根据场所标识和路线标识中的一个、当前小区信息以及当前事件信息，判断终端设备是否满足策略触发条件。
本申请可以预先将预设选网策略以及策略触发条件存储至选网策略交互单元中。该策略触发条件的具体内容可以参考步骤904，此处不再赘述。
当确定终端设备满足策略触发条件时，执行步骤1205；
当确定终端设备不满足策略触发条件时，返回步骤1201。
1205、选网策略交互单元获取目标选网策略。
其中，该预设选网策略与策略触发条件之间存在对应关系。所以本步骤可以获取终端设备当前满足的策略触发条件对应的目标选网策略。
该目标选网策略的详细内容可以参考图4、图5和图6所示实施例中所述的目标测量策略、以及图7和图8所示实施例中所述的目标搜网策略，此处不再赘述。
1206、选网策略交互单元向调制解调器选网模块发送目标选网策略。
1207、调制解调器选网模块根据目标选网策略进行选网处理，得到处理结果。
选网处理过程可以参考图4、图5和图6以及图7和图8中所示实施例，此处不再赘述。
可选的，在步骤1207之后，还可以包括步骤1208。
1208、调制解调器选网模块向选网策略交互单元发送处理结果。
其中，该处理结果包括图5或图6所示实施例中所述的测量结果；或，图7或图8所示实施例中所述的搜索结果。
1209、选网策略交互单元根据处理结果，判断更新目标选网策略还是删除目 标选网策略。
如果更新目标选网策略，则执行步骤1210；
如果删除目标选网策略，则执行步骤1211。
1210、执行目标选网策略的更新。
应理解，在更新过程中可以调整目标选网策略中的一项或多项参数。
1211、选网策略交互单元向调制解调器选网模块发送删除指令。
其中，该删除指令用于指示删除目标选网策略。
1212、调制解调器选网模块根据删除指令，删除目标选网策略。
需要说明的是，选网策略交互单元需要将存储的目标选网策略进行删除。在调制解调器选网模块删除目标选网策略之后，需要根据历史频点进行网络搜索，或者，根据当前小区的邻小区进行小区测量。
通过实施本实施例，由于智能选网主控模块能够根据历史信息学习到不同固定路线或不同固定场所对应的选网策略及策略触发条件，然后终端设备在满足策略触发条件时，智能选网主控模块能将选网策略发送给调制解调器选网模块，以便调制解调器选网模块进行选网处理。这样，增加了智能选网主控模块与调制解调器选网模块的交互，使得调制解调器选网模块能够根据搜网策略交互单元中的预设选网策略，针对性地执行选网处理，减少了终端功耗。
