Description

网络选择的方法和装置
本申请要求于2020年02月19日提交中国专利局、申请号为202010105793.9、申请名称为“网络选择的方法和装置”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
本申请涉及通信领域，并且更具体的，涉及网络选择的方法和装置。
背景技术
现网大数据统计结果显示，终端设备中调制解调器(modem)的功耗占到整机功耗的64％。其中，待机功耗和数据业务功耗是modem功耗的主要组成部分。例如，对于典型用户，待机功耗占比为23.24％。
目前，如果终端设备处于空闲(idle)态，则终端设备可以通过测量，选择满足R准则的邻区进行小区重选。如果终端设备处于连接(connected)态，则终端设备可以通过网络侧配置的邻区测量，上报A3事件来进行小区切换。这样，终端设备只能将邻区的信号强度这一单一维度作为下一跳小区的判断标准。这样，会造成终端设备测量的邻区的数量较多，导致modem功耗较高。
因此，如何降低终端设备的功耗是亟需解决的问题。
发明内容
本申请提供一种网络选择的方法和装置，使得终端设备能够有针对性的进行网络搜索，从而有助于降低终端设备的功耗。
第一方面，提供了一种网络选择的方法，该方法应用于终端设备。该方法包括以下流程或步骤。
获取第一信息，所述第一信息包括所述终端设备驻留的小区的小区信息；
从所述小区信息中获取第一小区信息或第二小区信息，其中，所述第一小区信息为所述终端设备在固定路线中驻留的小区的小区信息，所述第二小区信息为所述终端设备在固定场所中驻留的小区的小区信息；
根据预设规则对所述第一小区信息或所述第二小区信息进行预处理，获取有效驻留小区，其中，所述有效驻留小区包括第一有效驻留小区或第二有效驻留小区，所述第一有效驻留小区是根据第一预设规则对所述第一小区信息进行预处理获得的，所述第二有效驻留小区是根据第二预设规则对所述第二小区信息进行预处理获得的；
获取第二信息，所述第二信息包括所述终端设备当前驻留的第一小区的小区信息；
确定所述第一小区的小区信息为固定路线中的小区信息，或为固定场所中的小区信息；
当所述第一小区的小区信息为固定路线中的小区信息，在所述第一有效驻留小区中确 定第二小区，当所述第一小区的小区信息为固定场所中的小区信息时，在所述第二有效驻留小区中确定所述第二小区，其中，所述第二小区为所述终端设备在所述第一小区之后的下一个驻留小区。
因此，本申请实施例能够对终端设备驻留的小区的小区信息进行固定路线或固定场所分类，并根据预设规则对不同的分类进行不同的预处理，获取不同分类下终端设备的有效驻留小区，然后根据不同分类下的有效驻留小区，生成适用于该终端设备当前的选网策略，该选网策略用于指示终端设备在当前驻留的小区的下一跳小区，使得终端设备能够有针对性的进行网络搜索，从而有助于降低终端设备的功耗。
结合第一方面，在第一方面的某些实现方式中，所述小区信息中还包括所述终端设备从所述驻留的小区切换至下一跳小区时在驻留的小区中的信号接收功率；
所述方法还包括：
根据至少一个所述信号接收功率，确定所述终端设备在所述驻留的小区中的小区测量门限；
其中，所述小区测量门限包括起测门限和/或逃离门限，所述起测门限为开始对所述驻留的小区的下一跳小区进行小区测量的门限，所述逃离门限为对所述驻留的小区的邻小区进行小区测量的门限，其中，所述小区测量门限是根据所述至少一个信号接收功率中的最大信号接收功率确定的，所述逃离门限是根据所述至少一个信号接收功率中的最小信号接收功率确定的。
由于本申请实施例能够使得终端设备在第一小区中的信号接收功率大于起测门限(此时可以认为终端设备在第一小区中的信号较好)时，不对特定邻小区或所有预测的邻小区进行测量，而在第一小区中的信号接收功率小于或等于该起测门限(此时可以认为终端设备在第一小区中信号不好)时，才对特定邻小区或所有预测的邻小区进行测量，从而有助于减少对终端设备测量的浪费，减小终端设备的功耗。
另外，本申请实施例能够使得终端设备在第一小区中的信号接收功率小于或等于逃离门限(此时可以认为终端设备在第一小区中的信号已经很差了)时，按照现有对邻小区的测量机制进行小区测量，而不是只对预测的小区(例如第二小区)进行测量，从而有助于提高终端设备测量到邻小区的概率。
因此，本申请实施例通过获取终端设备在小区切换路径中切换至下一跳小区时在第一小区中的接收功率，并根据该接收功率，确定终端设备在第一小区中进行小区测量的起测门限和/或逃离门限，使得终端设备可以根据起测门限和/或逃离门限进行小区测量，从而有助于减少终端设备的测量的邻区的数量，或者测量邻区的次数，或者进行小区重选的次数，进而有助于降低终端设备的功耗。
可选的，起测门限还可以通过对最大信号接收功率进行偏移获得，例如为最大信号接收功率与δ 1之和。另外，逃离门限还可以通过对最小信号接收功率进行偏移获得，例如为最小信号接收功率与δ 2之和。这里，δ 1或δ 2可以为正值，或负值，本申请实施例对此不做限定。
结合第一方面，在第一方面的某些实现方式中，当在所述小区信息中获取第一小区信息时，所述第一有效驻留小区中包括所述第一小区和所述第二小区，所述第二小区为所述第一小区在固定路线上的历史下一跳小区，所述方法还包括：
在所述终端设备在所述第二小区发生掉网后，
当t＜T min时，确定关闭所述终端设备的小区测量。
此时，终端设备在该时间段即将，或已经没有可用的网络，此时如果终端设备继续进行小区测量，有很大的可能是搜索不到网络的。基于此，本申请实施例可以通过在小于T min的时间段关闭终端设备的小区测量，来降低终端设备的功耗。
当T min≤t＜k*T min+(1-k)T max时，确定将所述终端设备的测量间隔配置为第一测量间隔，其中，0＜k＜1。
当t≥k*T min+(1-k)T max时，确定将所述终端设备的测量间隔配置为第二测量间隔，其中，所述第二测量间隔小于所述第一测量间隔；
在满足T min≤t＜k*T min+(1-k)T max时，终端设备恢复网络的可能性仍然不是很大，此时可以通过设置长测量间隔，使得终端设备不需要进行频繁的邻区测量，从而有助于降低终端设备的功耗。在满足t≥k*T min+(1-k)T max时，终端设备恢复网络的可能性已经很大了，此时可以通过设置短时间测量间隔，有助于使得终端设备能够更快速恢复网络。
其中，t表示所述终端设备在所述第二小区中的掉网时刻之后的时长，T max表示统计得到的所述终端设备在所述第二小区掉网后恢复连接的最大恢复时间，T min表示统计得到的所述终端设备在所述第二小区掉网后恢复连接的最小恢复时间。
因此，本申请实施例通过判断终端设备在历史记录中是否在第二小区中掉网，并终端设备在第二小区发生掉网的情况下，根据终端设备的历史掉网之后的恢复时间，生成适用于终端设备在当前在第二小区掉网之后的不同时间段的测量策略，使得终端设备可以有针对性的进行小区测量，从而有助于减少终端设备的无效测量，进而有助于降低终端设备的功耗。
结合第一方面，在第一方面的某些实现方式中，当在所述小区信息中获取第一小区信息时，所述第一有效驻留小区中包括所述第一小区，所述第二小区和第三小区，所述第二小区和所述第三小区是所述第一小区在固定路线上的两个不同的历史下一跳小区；
其中，所述第二小区作为所述终端设备在所述第一小区的下一跳节点的第一频数，大于所述第三小区作为所述终端设备在所述第一小区的下一跳节点的第二频数；或者
所述终端设备在所述第二小区中的第一信号强度大于所述终端设备在所述第三小区中的第二信号强度；或者
所述终端设备在所述第二小区中的第一功耗大于所述终端设备在所述第三小区中的第二功耗，其中，所述第一功耗是根据所述终端设备在所述第二小区中的不连续接收DRX周期和无效无线资源控制RRC连接时长确定的，所述第二功耗是根据所述终端设备在所述第三小区中的不连续接收DRX周期和无效无线资源控制RRC连接时长确定的。
因此，本申请实施例通过获取终端设备在固定路线上的小区切换路径，并在该小区切换路径中存在当前驻留的第一小区时，根据该小区切换路径中的第一小区的下一跳小区，预测终端设备当前在第一小区中的下一跳小区，使得终端设备可以根据预测的下一跳小区有针对性地进行搜网，从而有助于减少终端设备测量的邻区的数量，或者进行小区重选的次数，进而有助于降低终端设备的功耗。

结合第一方面，在第一方面的某些实现方式中，所述去除所述终端设备乒乓切换的小区，包括：
在所述第一小区标识列表上设置第一时间窗，所述第一时间窗包括所述第一小区标识列表上的连续3个小区标识；

在满足与所述第一小区标识之前相邻的第二小区标识与所述第一个小区标识相同的条件时，在所述第一小区标识列表中删除所述第二个小区标识至所述第二小区标识之间的小区标识；
在满足所述第二小区标识与所述第一个小区标识不同的条件时，在所述第一小区标识列表中删除所述最后一个小区标识至所述第二小区标识之间的小区标识。
这样，本申请实施例能够获得不包含两个小区的乒乓小区的小区切换路径。
结合第一方面，在第一方面的某些实现方式中，所述去除所述终端设备乒乓切换的小区，包括：
在所述第一小区标识列表上设置第二时间窗，所述第二时间窗包括所述第一小区标识列表上的连续4个小区标识；

在满足所述第四小区标识与所述第一个小区标识不同，且所述第四小区标识与所述第二个小区标识不同的条件时，在所述第一小区标识列表中删除所述最后一个小区标识至所述第四小区标识之间的小区标识。
这样，本申请实施例能够获得不包含三个小区的乒乓小区的小区切换路径。
结合第一方面，在第一方面的某些实现方式中，所述根据预设规则对第一小区信息或第二小区信息进行预处理，获取有效驻留小区，包括：
当在所述小区信息中获取所述第二小区信息时，在所述第二小区信息对应的小区中确定所述终端设备驻留时长最长、功耗最低或接收信号强度最强的至少两个小区，以获取所述第二有效驻留小区，其中，所述第二有效驻留小区中包括所述至少两个小区；

当所述第一小区属于所述至少两个小区，且所述终端设备在所述第一小区与不属于所述至少两个小区的第五小区之间乒乓切换时，将所述至少两个小区中除所述第一小区之外的其他小区作为所述第二小区。
因此，本申请实施例通过获取终端设备在固定场所中小区驻留的历史记录，并根据终端设备在该固定场所中的小区中的历史驻留情况，预测终端设备当前在第一小区中的下一跳小区，使得终端设备可以根据预测的小区有针对性的进行搜网，从而有助于减少终端设备测量的邻区的数量，或者测量邻区的次数，或者进行小区重选的次数，进而有助于降低终端设备的功耗。

在一些实施例中，调制解调器140可以获取终端设备驻留的小区的小区信息，以及该小区信息对应的时间戳，并将该小区信息以及该小区信息对应的时间戳发送给选网主控单元130。
作为一种实现方式，调制解调器140可以周期性地向选网主控单元130发送小区信息以及时间戳。作为另一种实现方式，调制解调器140可以实时地向选网主控单元130发送小区信息以及时间戳。作为另一种实现方式，选网主控单元130可以向调制解调器140请求预设时间段内终端设备的小区驻留的历史记录。响应于选网主控单元130的请求，调制解调器140可以将该预设时间段中终端设备驻留的小区的小区信息以及时间戳发送给选网主控单元130。
对应的，网主控单元130可以接收并保存该小区信息和时间戳，比如，将该小区信息和时间戳保存在缓存中。这样，选网主控单元130可以获知终端设备当前驻留的小区，以及终端设备的小区驻留的历史记录。

作为一种实现方式，传感器120可以周期性地向选网主控单元130发送传感器信息以及时间戳。作为另一种实现方式，调制解调器140可以实时地向选网主控单元130发送传感器信息以及时间戳。作为另一种实现方式，选网主控单元130可以向调制解调器140请求预设时间段内终端设备的传感器信息。响应于选网主控单元130的请求，调制解调器140可以将该预设时间段中终端设备的传感器信息以及时间戳发送给选网主控单元130。
选网主控单元130在确定出终端设备在当前驻留小区的下一跳小区之后，可以将该下一跳小区发送给调制解调器140。调制解调器140可以根据该下一跳小区，进行有针对性的搜网，例如只对该下一跳小区进行测量，从而达到降低终端设备功耗的效果。
在一些实施例中，调制解调器140还可以向选网主控单元130反馈策略的执行结果，使得选网主控单元130能够进一步根据策略的执行结果，对选网策略进行优化。
因此，本申请实施例中，终端设备能够根据其小区驻留的历史记录，确定当前驻留小区的下一跳小区。相对于现有技术中的终端设备只能将邻区的信号强度这一单一维度作为下一跳小区的判断标准，本申请实施例中终端设备能够根据终端设备的小区驻留的历史记录进行网络选择，有助于使得终端设备能够有针对性地进行网络搜索，从而达到降低终端设备功耗的效果。

在本申请实施例中，对步骤201、202，以及203的先后顺序不做限定。例如，步骤201可以在步骤202或203之前发生，或者在步骤202或203之后发生，这些都在本申请实施例的保护范围之内。另外，本申请实施例中，也可以不需要执行步骤201或203，但是本申请实施例对此不做限定。
204，环境感知单元1310进行固定路线或固定场所分类。
具体而言，环境感知单元1310可以在步骤202获取的小区信息中，识别并提取固定路线中终端设备驻留的小区的小区信息(即第一小区信息)，或者识别并提取固定场所中终端设备驻留的小区的小区信息(即第二小区信息)。也就是说，环境感知单元1310可以进行路线识别或者场景识别，提取不同场景下的小区信息。
作为示例，环境感知单元1310中的路线及场景识别模块1312可以根据采集模块1311获取的信息，对步骤202中获取的小区信息进行固定路线或固定场所分类，即识别并提取出采集模块1311获取的小区信息中的固定路线场景下的小区信息，或者识别并提取出采集模块1311获取的小区信息中的固定场所场景下的小区信息。
示例性的，固定场所可以为用户经常固定停留的场所，例如家、学校、公司等。在固定场所上，终端设备可以驻留在该固定场所范围中的一个或多个小区中。
示例性的，固定路线可以为用户出行时常用路线，例如可以为用户从家到学校的路线，或者用户从家到公司的路线等，本申请实施例对此不做限定。在该固定路线上，终端设备会依次驻留在某些固定的小区中。
在一些实施例中，可以根据终端设备在该小区信息对应的小区中驻留的时间信息，或者终端设备在该小区信息对应的小区中驻留时连接的WiFi的标识，或者传感器信息，或者其他信息，识别终端设备所处的场景，本申请实施例对此不做限定。
作为一个示例，可以根据终端设备在小区中驻留的时间段，区分该小区是固定路线还是固定场所的小区。其中，该时间段可以预先设置在终端设备中，但是本申请实施例并不限于此。
例如，由于用户通常在工作日中的晚上12点至早上6点位于家中，因此可以将工作日中的晚上12点至早上6点中终端设备驻留的小区确定为固定场所中的小区，即工作日中的晚上12点至早上6点时间段中，终端设备处于固定场所的场景中。同时，用户通常在工作日中的早上9点至下午5点位于公司，因此还可以将该工作日中的早上点至下午5点中终端设备驻留的小区确定为固定尝试中的小区，即工作日中的晚上12点至早上6点时间段中，终端设备处于固定场所的场景中。
又例如，由于用户通常在工作日中的早上7点至9点从家去往公司，在下午5点至7点从公司去往家中，因此可以将工作日中的早上7点至9点，以及下午5点至7点中终端设备驻留的小区分别确定为固定路线中的小区，即工作日中的早上7点至9点，下午5点至7点的时间段中，终端设备均处于固定路线的场景中。
由于用户在工作日的活动较为规律，因此根据时间段区分固定路线和固定场所的小区的这种分类方式的好处在于，既可以降低小区分类的复杂度，又能准确地对小区进行分类。
作为另一个示例，可以根据终端设备在小区中驻留时连接的WiFi的标识，区分该小 区是固定路线还是固定场所的小区。
例如，当终端设备连接用户家中，或公司中的WiFi时，终端设备驻留的小区为固定场所中的小区，即终端设备处于固定场所的场景下。
又例如，当终端设备与用户家中的WiFi失去连接，并在一段时间之后连接到了公司的WiFi时，在这期间终端设备驻留的小区为固定路线中的小区，即终端设备处于固定路线的场景下。或者，当终端设备与用户公司的WiFi失去连接，并在一段时间之后连接到家中的WiFi时，在这期间终端设备驻留的小区也为固定路线中的小区，即终端设备处于固定路线的场景下。
作为另一个示例，可以根据终端设备在小区中驻留时，终端设备中的传感器信息，区分该小区是固定路线还是固定场所的小区。
例如，当传感器信息表示在某一时间段中终端设备大部分处于运动状态时，则在这个时间段中，终端设备驻留的小区可以为固定路线中的小区，即终端设备处于固定路线场景中。当传感器信息表示在某一时间段中终端设备大部分处于静止状态时，则在这个时间段中，终端设备驻留的小区可以为固定场所中的小区，即终端设备处于固定场所场景中。
可以理解的是，上述区分固定路线和固定场所的分类方法可以任意组合，本申请实施例对此不做限定。
例如，可以根据预先设置的时间段，比如工作日中的晚上12点至早上6点的时间段中终端设备连接的WiFi的标识，确定终端设备是否处于固定场所的场景中。比如，当在该预设时间段终端设备连接的WiFi为家中的WiFi时，可以确定在该时间段中终端设备驻留的小区确定为固定场所中的小区，即该时间段中，终端设备处于固定场所的场景中。又比如，当在该预设时间段终端设备连接的WiFi不是家中的WiFi时，可以确定在该时间段中终端设备驻留的小区不是固定场所中的小区，即该时间段中，终端设备没有处于固定场所的场景中。
205，策略交互单元1320对小区信息进行学习。
本申请实施例中，策略交互单元1320可以根据环境感知单元1310获取到的第一小区信息或第二小区信息，分别对不同场景下的小区信息进行学习，获取学习结果。根据该学习结果，可以确定当前驻留小区的下一跳小区。本申请实施例中，第一小区可以为当前驻留小区的一个示例，第二小区可以为下一跳小区的一个示例，
在一些实施例中，策略交互单元1320中的学习模块1321可以学习出适用于不同场景中终端设备的有效驻留小区。示例性的，学习模块1321可以根据预设规则对第一小区信息或第二小区信息进行预处理，获取有效驻留小区。当根据第一预设规则对第一小区信息进行预处理时，可以获得第一有效驻留小区。当根据第二预设规则对第二小区信息进行预处理时，可以获得第二有效驻留小区。有效驻留小区包括该第一有效驻留小区或第二有效驻留小区。
示例性的，第一预设规则可以为去除第一小区信息对应的小区中的终端设备乒乓切换的小区。本申请实施例中，可以将终端设备乒乓切换的小区称为乒乓小区。在具体实施例中，乒乓小区的个数可以为2个，或者3个，本申请实施例对此不做限定。
本申请实施例中，第二有效驻留小区的数量可以为一个，两个，或者大于两个。在一些可选的实施例中，可以预先定义第二有效驻留小区的数量，或者由用户选择第二有效驻留小区的数量，本申请实施例对此不做限定。
示例性的，当第二有效驻留小区的数量为一个时，该第二预设规则可以为从终端设备在第二小区信息对应的小区中确定出终端设备驻留时间最长、功耗最低、或者信号接收强度最强的一个小区，该小区即为该第二有效驻留小区。
当第二有效驻留小区的数量为至少两个时，第二预设规则可以为在第二小区信息对应的小区中确定终端设备驻留的时长最长、功耗最低或者接收信号强度最强的至少两个小区，并确定出该至少两个小区中终端设备乒乓切换的小区。
需要说明的是，这里仅以根据终端设备在小区中驻留的时长、功耗或者接收信号强度为例，说明选择第二有效驻留小区的依据，但是本申请实施例对此不作限定。例如，还可以同时根据终端设备在小区中驻留的时长、功耗或者接收信号强度中的至少两种信息来确定第二有效驻留小区。一些可能的实现方式中，可以预先配置终端设备根据在小区中驻留的时长、功耗或者接收信号强度中的至少一种，作为选择第二有效驻留小区的依据，或者由用户选择根据终端设备在小区中驻留的时长、功耗或者接收信号强度中的至少一种，作为选择第二有效驻留小区的依据，本申请实施例对此不作限定。
在一些实施例中，可以周期性的根据步骤202或203中采集到的数据执行步骤204和步骤205的操作，即对采集到的小区信息进行固定路线或固定场所分类，或者以及对个分类下的小区信息进行进一步的学习。例如，可以以3天为一个周期，或者7天为一个周期，本申请实施例对此不作限定。
在一些实施例中，当终端设备执行完一次步骤202至205的操作之后，很长的一段时间(例如一个月，三个月，一年等)将不再执行步骤202至205。当用户希望重新获取小区信息，并重新对小区信息进行分类以及进一步学习时，或者终端设备检测到用户更换了工作的城市，或者更换了家庭或公司住所时，可以再次执行步骤201至步骤205。
206，确定在当前驻留小区的选网策略。
作为示例，可以根据学习模块1321学习结果，确定出适合当前驻留的第一小区的选网策略，即预测当前驻留小区的下一跳小区，即第二小区。其中，该下一跳小区可以为功耗最优小区。
示例性的，采集模块1311可以获取终端设备当前驻留的第一小区的小区信息，路线及场景识别模块1312识别该第一小区的小区信息是否为固定路线中的小区信息(即终端设备当前是否处于固定路线场景中)，或第一小区的小区信息是否固定场所中的小区信息(即终端设备当前是否处于固定场所场景中)。
一些可能的实现方式中，可以根据当前时刻的时间信息，或者根据当前时刻连接的WiFi的标识，或者传感器信息，确定当前所处的场景。例如，当当前时刻为工作日的早上8点，或者终端设备处于运动状态时，可以确定终端设备当前处于固定路线场景，即第一小区的小区信息为固定路线中的小区信息。又例如，当当前时刻为晚上10点，或者当前时刻终端设备设备连接的WiFi为家或公司中的WiFi，或者终端设备处于静止状态时，可以确定终端设备当前处于固定场所场景，即第一小区的小区信息为固定场景中的小区信息。
然后，策略匹配模块1322可以根据当前小区的小区信息的识别结果，确定与当前场景匹配的选网策略。当处于固定路线场景时，即第一小区的小区信息为固定路线中的小区信息时，可以在第一有效驻留小区中确定第二小区。当处于固定场所场景时，即第一小区的小区信息为固定场所中的小区信息时，可以在第二有效驻留小区中确定第二小区。
作为一种可能的实现方式，可以在获取终端设备当前驻留的第一小区的小区信息之前，执行步骤204和/或205，这样有利于快速预测当前驻留小区的下一跳小区。
作为另一种可能的实现方式，也可以在获取终端设备当前驻留的第一小区的小区信息之后，在执行步骤204和/或步骤205，本申请实施例对此不作限定。
207，策略交互单元1320向modem140进行策略下发。
作为示例，策略交互单元1320将与当前场景匹配的学习策略，即在步骤206中获取的选网策略下发给modem140。
因此，本申请实施例能够对终端设备驻留的小区的小区信息进行固定路线或固定场所分类，并根据预设规则对不同的分类进行不同的预处理，获取不同分类下终端设备的有效驻留小区，然后根据不同分类下的有效驻留小区，生成适用于该终端设备当前的选网策略，该选网策略用于指示终端设备在当前驻留的小区的下一跳小区，使得终端设备能够有针对性的进行网络搜索，从而有助于降低终端设备的功耗。
进一步的，本申请实施例中的选网主控单元能够与AP、modem以及传感器进行交互，共同实现选网功能，基于此本申请实施例的系统架构能够与现有搜网架构兼容。因此，本申请实施例的系统架构具有低耦合、高内聚以及智能化处理等特性，并且还具有便于移植和升级的特性。
下面，结合图3至图15，描述在固定路线场景下，本申请实施例提供的网络选择的方法。
图3示出了本申请实施例提供的一种网络选择的方法300示意性流程图。示例性的，方法300可以由上文中的选网主控单元130执行。具体可以包括步骤301至步骤305。
301，采集小区信息。
示例性的，可以由采集模块1311执行步骤301。具体的，可以参见图2中步骤202的描述，这里不再赘述。
302，获取原始的小区切换路径。
示例性的，路线及场景识别模块1312可以根据采集模块1311获取的小区信息，获取终端设备的原始的小区切换路径，即在采集模块1311获取的小区信息中提取原始的小区切换路径上的小区的小区信息。这里，该原始的小区切换路径上包括终端设备在固定路线上按照时间顺序依次驻留的小区。作为一个具体的例子，经过一段时间的数据采集，在从家到公司的固定路线上，可以获得多条原始的小区切换路径，例如A-B-C-D-E、A-B-C-D-C-D-E，A-B-C-B-C-D-E、A-B-F-D-E、A-B-C-F-D-E等。其中，A、B、C、D、E、F等用于标识小区。
本申请实施例中，小区切换路径可以对应小区标识列表，其中该小区标识列表包括与小区切换路径上的至少两个小区一一对应的至少两个小区标识，并且该至少两个小区标识在小区标识列表中的顺序与该至少两个小区在小区切换路径中的顺序相同。
作为示例，原始的小区切换路径可以对应原始的小区标识列表，该原始的小区标识列表中包括终端设备在固定路线上按照时间顺序依次驻留的小区的小区标识。
可选的，在步骤302中，终端设备还可以获取终端设备在小区切换路径中的每次切换前在驻留小区中的信号强度，例如RSRP等，本申请实施例对此不做限定。
303，判断采集次数是否大于或等于m。当采集次数小于m时，继续执行步骤301。当采集次数大于m时，执行步骤304。这里，m为正整数。示例性的，m可以预先设置在 采集模块1311中。
本申请实施例通过设置采集次数大于或等于m，能够有助于采集模块1311获取足够多的小区历史记录，进而有助于提高本申请实施例学习选网策略的准确性。
304，去除乒乓小区，生成有效的小区切换路径。
示例性的，学习模块1321可以执行步骤304。也就是说，步骤304可以为图2中的步骤205在固定路线场景下的一个具体示例。示例性的，步骤205中的第一有效驻留小区包括这里的至少一个(即一个或多个)有效的小区切换路线对应的小区。
本申请实施例中，当终端设备在两个小区或三个小区之间乒乓切换(即频繁来回切换)时，可以称该两个小区或三个小区为乒乓小区。示例性的，当终端设备处在多个小区的边界的时候，该多个小区的信号强度相当，使得终端设备在移动的过程中可能接入任何一个小区，进而可能导致终端设备在该多个小区之间的乒乓切换。
一种可能的实现方式，当终端设备在某个时间段在两个小区(或三个小区)之间切换的次数大于预设阈值时，可以认为该两个小区(或三个小区)为乒乓小区。作为示例，该时间段可以为单位时间，或预设的时间段，本申请实施例对此不做限定。
一些可选的实施例中，当小区切换路径中包含乒乓小区时，可以去除该小区切换路径中的乒乓小区，获得有效的小区切换路径。当根据有效的小区切换路径确定选网策略时，能够确保终端设备稳定驻留在该选网策略指示的下一跳小区中。
继续步骤304中的例子，通过对在从家到公司的固定路线中多条原始的小区切换路径进行去乒乓操作，最终可能获得从家到公司的固定路线中的三条有效的小区切换路径：A-B-C-D-E、A-B-F-D-E和A-B-C-F-D-E。
示例性的，可以根据小区切换路径对应的小区标识列表，去除该小区切换路径中的乒乓小区。下面结合图4至图5描述本申请实施例提供的两种去除乒乓小区的方法。

801，设置时间窗为4，获取该时间窗内的三个小区标识：A n，A n+1，A n+2，A n+3。
图9示出了小区标识列表和时间窗的另一个示例。图9中的小区标识列表可以参考图5中的描述，这里不再赘述。一个示例，当n＝1时，时间窗中包括的三个小区标识为A 1，A 2，A 3，A 4。

805，删除A n+1至A k-1。
图10示出了删除小区标识列表的一个具体示例。如图6第一行所示，A n至A k依次分别为A、B、C、A、…、A、D。其中，A k-1为A，A n为A，即A k-1与A n相同，此时将A n+1至A k-1之间的小区标识删除(即删除乒乓小区B、C、A…A)，可以获得如图10第二行所示的小区列表标识(即只包含A、D的小区标识列表)，此时小区标识A n+1至A k-1已经被删除。也就是说，从时间窗中的第二个小区标识开始删除，直至最后一个乒乓小区。
然后，如图10中第三行所示，可以将A k作为该小区标识列表中的第n+1个小区标识，将A k+1作为该小区标识列表中的第n+2个小区标识，并以此类推。
需要说明的是，本申请实施例中，A、B、C、D等为具体的小区标识的示例，但是本申请实施例并不限于此。

807，删除A n+2至A k-1。
图11示出了删除小区标识列表的另一个具体示例。如图11第一行所示，A n至A k依次分别为A、B、C、A、…、B、D。其中，A k-1为B，A n+1为B，即A k-1与A n+1相同，此时将A n+2至A k-1之间的小区标识删除(即删除乒乓小区C、A…B)，可以获的如图11第二行所示的小区列表标识(即只包含A、B、D的小区标识列表)，此时小区标识A n+2至A k-1已经被删除。也就是说，从时间窗中的第三个小区标识开始删除，直至最后一个乒乓小区。
然后，如图11中第三行所示，可以将A k作为该小区标识列表中的第n+2个小区标识，将A k+1作为该小区标识列表中的第n+3个小区标识，并以此类推。
808，删除A n+3至A k-1。

809，移动窗口至下一个位置，并且将n的值加1，即n++。
810，判断窗口之后是否还存在A n+4。
当存在A n+4时，返回继续执行802。当不存在A n+4时，结束流程。
图8的流程结束后，能够获得不包含三个小区的乒乓小区的小区切换路径。
一些可能的实现方式中，在对原始的小区切换路径去除乒乓小区时，可以先去除包含两个小区的乒乓小区。之后，可以在去除两个小区的乒乓小区的小区切换路径上继续去除包含三个小区的乒乓小区。
305，确定在当前驻留小区的选网策略。
示例性的，策略匹配模块1322可以根据在304中获取的有效小区切换路径，确定适合当前驻留的小区的选网策略，即预测当前驻留小区的下一跳小区。这里，步骤305可以为图2中的步骤206在固定路线下的一个具体示例。
下面结合图13和图14分别描述步骤305的两种具体的实现方式。
图13示出了本申请实施例提供的一种网络选择的方法1300的示意性流程图。如图13所示，方法1300可以包括步骤1301至步骤1305。示例性的，步骤1301可以由环境感知单元1310执行，步骤1302至1305可以由策略交互单元1320执行。
1301，确定当前服务的第一小区。
例如，采集单元1311可以获取当前服务的第一小区的小区信息，例如获取modem140实时发送的小区信息。路线和场景识别模块1312根据该第一小区的小区信息，确定当前服务的第一小区，并确定终端设备当前处于固定路线场景，即第一小区的小区信息为固定路线中的小区信息。
1302，在已有小区切换路径中是否存在第一小区。
作为一个示例，该已有的小区切换路径可以为步骤304中获取的有效的小区切换路径。
作为一种实现方式，策略匹配模块1322可以根据第一小区的小区标识，在已有小区切换路径对应的小区标识列表中寻找第一小区的小区标识。当一个小区标识列表中存在第一小区的小区标识时，则确定在该小区标识列表对应的小区切换路径中存在第一小区。当一个小区标识列表中不存在第一小区的小区标识时，则确定在该小区标识列表对应的小区切换路径中不存在第一小区。
当存在第一小区时，下一步执行1303。当不存在第一小区时，下一步继续执行1301。
1303，在已有小区切换路径中获取第一小区的下一跳小区。
作为一种实现方式，策略匹配模块1322可以将小区切换路径对应的小区标识列表中与该第一小区的小区标识相邻的下一个小区标识对应的小区作为第一小区的下一跳小区。
一些实施例中，当存在多个小区切换路径中均存在该第一小区的下一跳小区时，可以统计不同小区切换路径中的下一跳小区出现的频数，并确定出频数最高的至少两个下一跳小区，例如频数最高的前N个(topN)小区。
以已有有效的小区切换路径为A-B-C-D-E、A-B-F-D-E和A-B-C-F-D-E，当前驻留小区为小区B为例，假设A-B-C-D-E出现的频数为7，A-B-C-F-D-E出现的频数为8，A-B-F-D-E出现的频数为5，在已有小区切换路径中存在当前小区B，且小区C(可以称为第二小区)作为小区B的频数为(7+8)，小区F(可以成为第三小区)作为小区B的频数为5，可以确定小区C和F为频数最高的前2个小区，即top2小区。
可选的，1304，获取终端设备在至少一次切换至下一跳小区时的至少一个信号接收功率，该信号接收功率为终端设备对第一小区的信号的接收功率(即终端设备在第一小区中的信号强度)。作为示例，接收功率可以为RSRP，但是本申请实施例并不限于此。
作为一个示例，终端设备在可以在上文图3中的步骤302中获取的该终端设备每次切换前在驻留小区中的信号强度中，获取终端设备由第一小区切换至下一跳小区时对第一小区的信号的接收功率。
一些实施例中，当已有小区切换路径中包含多个小区切换路径，且该多个小区切换路径中该第一小区的下一跳小区相同，比如均为第二小区时，可以分别获取终端设备多次从 第一小区切换至第二小区时，对应的多个在第一小区中的信号接收功率。
作为示例，在其中一个小区切换路径中，终端设备由第一小区切换到第二小区时，在第一小区中的信号接收功率为-85dbm。在另一个小区切换路径中，终端设备由第一小区切换到第二小区时，在第一小区中的信号接收功率为-90dbm。在另一个小区切换路径中，终端设备由第一小区切换到第二小区时，在第一小区中的信号接收功率为-100dbm。
一些实施例中，当已有小区切换路径中包含多个小区切换路径，且该多个小区切换路径中该第一小区的下一跳小区不相同时，可以分别获取终端设备多次从第一小区切换至各个下一跳小区时，对应的多个在第一小区中的信号接收功率。
作为示例，在其中一个小区切换路径中，终端设备由第一小区切换到第二小区，在第一小区中的信号接收功率为-85dbm。在另一个小区切换路径中，终端设备由第一小区切换到第三小区，在第一小区中的信号接收功率为-75dbm。
1305，预测当前驻留小区的下一跳小区。
一个示例，策略匹配模块1322可以将终端设备在步骤1303中获取的下一跳小区作为终端设备在当前时刻之后选择的第一小区的下一跳小区。例如，可以将切换频数最高的小区(例如第二小区)作为在当前驻留小区的下一跳小区，或者可以在切换频数最高的前n小区(例如前2个(top 2)小区，即第二小区和第三小区)中确定当前驻留小区的下一跳小区。
当预测当前驻留小区的下一跳小区为切换频数最高的前n小区时，终端设备可以只对该前n小区进行小区测量，并可以进一步将该前n个小区的信号强度作为下一跳小区的判断标准。
因此，本申请实施例通过获取终端设备在固定路线上的小区切换路径，并在该小区切换路径中存在当前驻留的第一小区时，根据该小区切换路径中的第一小区的下一跳小区，预测终端设备当前在第一小区中的下一跳小区，使得终端设备可以根据预测的下一跳小区有针对性地进行搜网，从而有助于减少终端设备测量的邻区的数量，或者进行小区重选的次数，进而有助于降低终端设备的功耗。
在一些可选的实施例中，当执行步骤1304时，还可以根据步骤1304中获取的接收功率大小，确定终端设备在当前时刻之后在第一小区中的小区测量门限。具体而言，该小区测量门限包括起测门限和/或逃离门限，其中起测门限指开始对下一跳小区进行小区测量的门限，逃离门限指恢复默认小区测量的门限，例如可以对所有的邻区进行小区测量的门限值。
一个示例，当获取了多次从第一小区切换到第二小区时对应的多个在第一小区中的信号接收功率时，可以根据该多个信号接收功率中的最大信号接收功率确定对于该第二小区的起测门限，和/或，根据该多个信号接收功率中的最小信号接收功率确定逃离门限。
作为一种实现方式，起测门限可以为该最大信号接收功率，逃离门限为该最小信号接收功率。例如，当3次从第一小区切换到第二小区时，对应的3个信号接收功率分别为-85dbm、-90dbm和-100dbm时，可以将-85dbm作为对该第二小区的起测门限，将-100dbm作为逃离门限。也就是说，当终端设备在第一小区中的信号接收功率小于或等于-85dbm时，开始对第二小区进行小区测量，当终端设备在第一小区中的信号接收功率小于或等于-100dbm时，恢复modem的默认测量配置，即终端设备对第一小区的所有的邻小区进行测量)，也就是说这时可以仅通过第一小区的邻区的信号强度这一单一维度作为下一跳小 区的判断标准。此时，该起测门限还可以称为在该第一小区中针对该第二小区的起测门限，该逃离门限还可以称为在该第一小区中针对该第二小区的逃离门限。
另一个示例，当获取了多次从第一小区切换到多个下一跳小区时对应的多个在第一小区中的信号接收功率时，可以根据该多个信号接收功率中的最大信号接收功率确定起测门限，和/或，根据该多个信号接收功率中的最小信号接收功率确定逃离门限。这时，当满足该起测门限时，可以对所有预测到的小区进行小区测量。
作为一种实现方式，起测门限可以为该最大信号接收功率，逃离门限为该最小信号接收功率。例如，当从第一小区切换到第二小区对应的两个信号接收功率为-85dbm，-100dbm，从第一小区切换到第三小区对应的信号接收功率为-75dbm时，可以将-75dbm作为对任意可能预测到的小区(比如第二小区和第三小区)的起测门限，将-100dbm作为逃离门限。也就是说，当终端设备在第一小区中的信号接收功率小于或等于-75dbm时，开始对可能预测到的小区进行小区测量，当终端设备在第一小区中的信号接收功率小于或等于-100dbm时，恢复modem的默认测量配置，即终端设备对第一小区的所有的邻小区进行测量)，也就是说这时可以仅通过第一小区的邻区的信号强度这一单一维度作为下一跳小区的判断标准。此时，该起测门限还可以称为在该第一小区中通用的起测门限，该逃离门限还可以称为在该第一小区中通用的逃离门限。
因此，本申请实施例能够使得终端设备在第一小区中的信号接收功率大于起测门限(此时可以认为终端设备在第一小区中的信号较好)时，不对特定邻小区(比如第二小区)或所有预测的邻小区(比如第二小区和第三小区)进行测量，而在第一小区中的信号接收功率小于或等于该起测门限(此时可以认为终端设备在第一小区中信号不好)时，才对特定邻小区(比如第二小区)或所有预测的邻小区(比如第二小区和第三小区)进行测量，从而有助于减少对终端设备测量的浪费，减小终端设备的功耗。
另外，本申请实施例能够使得终端设备在第一小区中的信号接收功率小于或等于逃离门限(此时可以认为终端设备在第一小区中的信号已经很差了)时，按照现有对邻小区的测量机制进行小区测量，而不是只对预测的小区(例如第二小区)进行测量，从而有助于提高终端设备测量到邻小区的概率。
需要说明的是，本申请实施例设置的起测门限相对现有技术而言更高，即更加严格。例如在网络设备配置的测量门限为-80dbm的情况下，本申请实施例的方案确定的起测门限可以为-70dbm，从而使得终端设备在信号质量还没有很差时就可以进行小区测量，从而有助于减少终端设备测量邻小区的次数。
在其他实现方式中，该起测门限还可以通过对最大信号接收功率进行偏移获得，例如为最大信号接收功率与δ 1之和。另外，逃离门限还可以通过对最小信号接收功率进行偏移获得，例如为最小信号接收功率与δ 2之和。这里，δ 1或δ 2可以为正值，或负值，本申请实施例对此不做限定。
作为示例，对于起测门限而言，当对最大信号接收功率的偏移(即δ 1)为正值时，由于最大信号接收功率通常为负值，会使得设置的起测门限值变大(即提高起测门限)，进而能够有助于实现晚点切换小区，从而有助于节省测量功耗。当对最大信号接收功率的偏移(即δ 1)为负值时，由于最大信号接收功率通常为负值，会使得设置的起测门限值变小(即降低起测门限)，进而能够有助于实现早点切换小区，从而有助于避免在信号不好时再进行切换。
类似的，对于逃离门限而言，当对最小信号接收功率的偏移(即δ 2)为正值时，会使得设置的逃离门限值变大，进而能够有助于实现晚点恢复modem的默认测量配置，有助于节省测量功耗。当对最小信号接收功率的偏移(即δ 2)为负值时，会使得设置的逃离门限值变小，进而能够有助于实现早点恢复modem的默认测量配置，有助于避免在信号不好时再进行切换。
在一些可选的实施例中，当不执行步骤1304时，可以预先配置起测门限或逃离门限，本申请实施例对此不做限定。
因此，本申请实施例通过获取终端设备在小区切换路径中切换至下一跳小区时在第一小区中的接收功率，并根据该接收功率，确定终端设备在第一小区中进行小区测量的起测门限和/或逃离门限，使得终端设备可以根据起测门限和/或逃离门限进行小区测量，从而有助于减少终端设备的测量的邻区的数量，或者测量邻区的次数，或者进行小区重选的次数，进而有助于降低终端设备的功耗。
图14示出了本申请实施例提供的另一种网络选择的方法1400的示意性流程图。如图14所示，方法1400可以包括步骤1401至1410。示例性的，步骤1401可以由环境感知单元1310执行，步骤1402至1410可以由策略交互单元1320执行。
1401，确定当前服务的第一小区。
1402，在已有小区切换路径中是否存在第一小区。
1403，在已有小区切换路径中获取第一小区的下一跳小区。
具体的，步骤1401至1403可以参见图13中步骤1301至1303中的描述，为了简洁，这里不再赘述。
1404，判断下一跳小区是否掉网。
这里，判断的是在当前时刻之前的已有路径中，终端设备在第一小区的下一跳小区中是否发生掉网。作为示例，当前时刻可以记为第一时刻。
当在下一跳小区中没有发生掉网时，下一步执行步骤1405。当在下一跳小区中发生掉网时，下一步执行步骤1410。
1405，获取第一信号强度和第二信号强度。
以下一跳小区包括第二小区和第三小区为例，可以获取终端设备驻留在第二小区中的信号强度(可以记为第一信号强度)，以及终端设备驻留在第三小区中的信号强度(可以记为第二信号强度)。
一个示例，信号强度可以为终端设备驻留在小区中的平均信号强度。一个具体的例子，第一信号强度可以为在第二小区中的RSRP的平均信号强度，记为RSRP#1，第二信号强度可以为在第三小区中的RSRP的平均信号强度，记为RSRP#2。
1406，判断第一信号强度和所述第二信号强度的差值的绝对值是否小于第三预设值。作为示例，判断是否满足abs(RSRP#1-RSRP#2)＜TH。
在不满足第一信号强度和所述第二信号强度的差值的绝对值是否小于第三预设值，即不满足abs(RSRP#1-RSRP#2)＜TH时，下一步执行1407。其中，TH是第三预设值的一个示例。在满足第一信号强度和所述第二信号强度的差值的绝对值是否小于第三预设值，即满足abs(RSRP#1-RSRP#2)＜TH时，下一步执行1408。
1407，根据第一信号强度RSRP#1和第二平均信号RSRP#2，生成选网策略。
示例性的，可以将所述第一信号强度和所述第二信号强度中较大信号强度对应的小区， 作为终端设备在所述第一时刻之后的下一跳小区，即将max(RSRP#1，RSRP#2)对应的小区作为终端设备在所述第一时刻之后的下一跳小区。
也就是说，当第一信号强度RSRP#1和第二平均信号RSRP#2之差的绝对值小于或等于阈值TH时，说明第一信号强度RSRP#1和所述第二平均信号RSRP#2的差别比较大，此时可以选择二者中的较大值对应的小区作为第一时刻之后的下一跳小区。
而当第一信号强度RSRP#1和第二平均信号RSRP#2之差的绝对值大于阈值TH时，说明第一信号强度RSRP#1和所述第二平均信号RSRP#2的差别比较小，此时还可以根据其他网络配置参数，进一步选择功耗最优的小区作为第一时刻之后的下一跳小区。具体的可以参见步骤1408的描述。
1408，确定第一功耗情况和第二功耗情况。其中，第一功耗情况可以终端设备在为第二小区的功耗情况，第二功率情况可以为终端设备在第三小区的功耗情况。
作为一种可能的实现方式，可以根据终端设备在小区中的不连续接收(discontinuous reception，DRX)周期和/或无效无线资源控制(radio resource control，RRC)连接时长，确定终端设备在该小区中的功耗情况。其中，无效RRC连接时长可以为在modem没有数据发送的时刻至RRC释放结束的时刻之间的时长。其中，DRX周期越大，终端设备的功耗越小，RRC连接时长越大，终端设备的功耗越小。
示例性的，可以对终端设备在小区中的DRX周期和RRC连接时长进行加权求和，求和得到的值可以用于表示终端设备在该小区中的功耗情况。如下公式(1)示出了功耗情况的一个具体的例子。
S＝SD*λ+SR*α           (1)
其中，S表示功耗情况得分，SD表示DRX周期得分，λ表示DRX周期得分的加权值，SR表示无效RRC连接得分，α表示无效RRC连接得分的加权值。由公式(1)可知，S值越大，对应的终端设备的功耗越小。
作为示例，λ的取值可以为0.6，α的取值可以0.4。
需要说明的是，不同的DRX周期对应的得分SD不同，不同的无效RRC连接时间对应的得分SR不同。其中，可以设置至少一个DRX周期门限值和至少一个无效RRC连接时长门限值，并根据该门限值，确定不同DRX周期对应的得分SD，以及不同无效RRC连接时间对应的得分SR。
图15示出了DRX门限值和无效RRC连接时长门限值的一个具体的示例。如图15所示，可以设置DRX门限值a 0和a 1，其中a 0＞a 1。作为示例，a 0取值可以为sf128，a 1取值可以为sf10。当DRX周期a满足a≤a 1时，该DRX周期为短周期，当满足a 1＜a≤a 0时，该DRX周期为长周期，当满足a＞a 0时，该DRX周期为非常长周期。
如图15所示，还可以设置无效RRC连接时长门限值t 0、t 1和t 2，其中t 2＞t 1＞t 0。作为示例，t取值可以为9s，t 1取值可以为15s，t 2取值可以为20s。当无效RRC连接时长a满足t≤t 0时，该无效RRC连接时长为非常短连接时长，当满足t 0＜t≤t 1时，该无效RRC连接时长为短连接时长，当满足t 1＜t≤t 2，该无效RRC连接时长为长连接时长，当满足t 0＜t≤t 1，该无效RRC连接时长为非常长连接时长。
表1示出了DRX周期(可表示为a)与其对应的得分SD的一个示例，表2示出了无效RRC连接时间(可表示为t)与其对应的得分SR的一个示例。
DRX的参数配置如下表1所示：

1409，根据第一功耗情况和第二功耗情况，确定当前驻留小区的下一跳小区。
示例性的，可以将第一功耗情况和第二功耗情况中较小功耗情况对应的小区，作为终端设备在当前小区的下一跳小区。例如，终端设备在b小区中的功耗情况得分可以表示为Sb，在c小区中的功耗情况得分可以表示为Sc，则此时可以将max(Sb，Sc)对应的小区作为终端设备在第一时刻之后选择的下一跳小区。
需要说明的是，以上步骤1405至1409仅以获取下一跳小区中的top2小区的信号强度为例进行描述。本申请实施例中还可以获取下一跳小区中的top3或top4或其他topN小区的信号强度，本申请实施例对此不做限定。当获取top3或top4或其他topN小区的信号强度时，其具体实现可以参照获取top2小区的信号强度的相关描述，可能需要做一些简单的适配，但是也在本申请实施例的保护范围之内。
示例性的，当获取的topN小区的信号强度时，可以判断该N个小区两两之间的信号强度的差值的绝对值是否小于第三预设值。
当该N个小区存在至少两个小区的信号强度的差值的绝对值不满足小于第三预设值时，可以根据该N个小区的信号强度，确定当前驻留小区的下一跳小区。例如，可以将该N个小区的信号强度值中最大信号强度对应的小区，作为终端设备的当前驻留小区的下一跳小区。
当该N个小区任意两个信号强度的差值的绝对值均满足小于第三预设值时，可以确定该N个小区的功耗情况，并根据该N个小区的功耗情况，确定当前驻留小区的下一跳小区。例如，将该N个小区中最小功耗对应的小区，作为终端设备的当前驻留小区的下一跳小区。
因此，本申请实施例通过判断终端设备在当前时刻之前是否在下一跳小区中掉网，并在下一跳小区没有掉网的情况下，根据终端设备在下一跳小区中的信号强度，确定当前驻 留小区的下一跳小区，使得终端设备可以有针对性的进行搜网，从而有助于减少终端设备测量的邻区的数量，或者测量邻区的次数，或者进行小区重选的次数，进而有助于降低终端设备的功耗。
1410，根据掉网后的恢复时间，生成在第一小区中的测量策略。
示例性的，当终端设备在第二小区发生掉网时，可以获取终端设备在第二小区中掉网后恢复的时间。然后，根据该恢复的时间，确定终端设备在第二小区中掉网后将采用的测量策略。
作为一种实现方式，可以统计历史记录中终端设备在第二小区中掉网后的最大恢复时间(记为T max)和最小恢复时间(可以记为T min)。此时，以终端设备在第二小区中掉网时刻起开始计时，在t时刻(即终端设备在第二小区中掉网之后的时长为t的时刻)的测量策略如下：
当t＜T min时，确定关闭终端设备的小区测量。
也就是说，在第二小区掉网之后的小于T min的时间段内，终端设备关闭在第一小区的小区测量。此时，终端设备在该时间段即将，或已经没有可用的网络，此时如果终端设备继续进行小区测量，有很大的可能是搜索不到网络的。基于此，本申请实施例可以通过在小于T min的时间段关闭终端设备的小区测量，来降低终端设备的功耗。
当T min≤t＜k*T min+(1-k)T max时，确定将终端设备的测量间隔配置为第一测量间隔，其中，0＜k＜1。一个示例，k可以取值为0.5。
也就是说，在第二小区掉网之后的大于或等于T min且小于k*T min+(1-k)T max的时间段内，将终端设备测量间隔配置为第一测量间隔。
当t≥k*T min+(1-k)T max时，确定将终端设备测量间隔配置为第二测量间隔。
也就是说，在第二小区掉网之后的大于或等于k*T min+(1-k)T max的时间段，将终端设备测量间隔配置为第二测量间隔。
其中，所述第二测量间隔小于所述第一测量间隔。作为一个示例，第一测量间隔可以称为长测量间隔，第二测量间隔可以称为短测量间隔。
本申请实施例中，在满足T min≤t＜k*T min+(1-k)T max时，终端设备恢复网络的可能性仍然不是很大，此时可以通过设置长测量间隔，使得终端设备不需要进行频繁的邻区测量，从而有助于降低终端设备的功耗。在满足t≥k*T min+(1-k)T max时，终端设备恢复网络的可能性已经很大了，此时可以通过设置短时间测量间隔，有助于使得终端设备能够更快速恢复网络。
因此，本申请实施例通过判断终端设备在历史记录中是否在第二小区中掉网，并终端设备在第二小区发生掉网的情况下，根据终端设备的历史掉网之后的恢复时间，生成适用于终端设备在当前在第二小区掉网之后的不同时间段的测量策略，使得终端设备可以有针对性的进行小区测量，从而有助于减少终端设备的无效测量，进而有助于降低终端设备的功耗。
下面，结合图16和图17，描述在固定场所下，本申请实施例提供的网络选择的方法。
图16示出了本申请实施例提供的一种网络选择的方法1600的示意性流程图。方法1600可以由上文中的选网主控单元130执行。具体可以包括步骤1601至步骤1607。
1601，采集小区信息。
示例性的，可以由采集模块1311执行步骤1601。具体的，可以参见图2中步骤202 的描述，这里不再赘述。
可选的，当采集次数小于m时，继续执行步骤1601。当采集次数大于m时，执行步骤1602。这里，m为正整数。示例性的，m可以预先设置在采集模块1311中。
1602，获取在第一区域中驻留的N个小区，其中N为正整数。
这里，第一区域可以为固定场所的一个示例，例如为家、学校、公司等，本申请实施例对此不做限定。
示例性的，路线及场景识别模块1312可以根据采集模块1311获取的小区信息，获取在终端设备在第一区域中驻留的一个或多个小区，即在采集模块1311获取的小区信息中提取在该第一区域中驻留的一个小区的小区信息。
然后，可以在该一个或多个小区中确定N个小区，其中，N为正整数。示例性的，可以由策略交互单元1320中的学习模块1321确定该N个小区。这里，该N个小区可以为终端设备在第一区域中驻留时间最长的topN小区，或者功耗最低的topN小区，或者接收信号强度最强的topN个小区。作为一个示例，当N取1时，该小区即为终端设备在第一区域中驻留时间最长，或者功耗最低，或者接收信号强度最强的小区。此时，该小区即为第二有效驻留小区的一个示例。
这样，当在N个小区确定终端设备将要驻留的小区时，能够确保终端设备稳定驻留在选网策略指示的小区中。
当N取值大于或等于2时，还需要执行步骤1603至1606。示例性的，在获取该N个小区之后，策略交互单元1320中的学习模块1321可以继续执行以下步骤1603至1606。也就是说，此时，确定该N个小区，以及下面的步骤1603至1606可以为步骤205中的在固定场所下的一个具体示例。其中，该N个小区即为第二有效驻留小区的一个示例。
下文以获取第一区域中驻留的N个小区为三个小区，即C1，C2和C3为例进行描述。需要说明的是，该N个小区还可以为两个小区，四个小区，或者更多小区，本申请实施例对此不做限定。当获取的小区的数量为两个、四个或者更多小区时，其具体实现可以参照获取第一区域中驻留的三个小区的相关描述，可能需要做一些简单的适配，但是也在本申请实施例的保护范围之内。
1603，获取在N个小区之间两两切换的次数。
例如，当在步骤1602中获取了三个小区C1，C2、C3时，学习模块1321可以获取终端设备在C1和C2之间切换的次数，在C1和C3之间切换的次数，在C2和C3之间切换的次数。
可选的，学习模块1321还可以获取终端设备在小区之间多次切换时对应的多个在当前服务小区中的信号接收功率，例如RSRP。例如，当终端设备由小区C1切换到小区C2时，获取终端设备在小区C1中的信号接收功率，比如为-85dbm；当终端设备由小区C2切换到小区C3时，获取终端设备在小区C2中的信号接收功率，比如为-82dbm；当终端设备由小区C3切换到C2时，获取终端设备在小区C3中的信号接收功率，比如为-90dbm等。
1604，判断单位时间切换次数是否大于门限值。示例性的，门限值可以为预先设置的。当单位时间切换次数不大于该门限值时，下一步为步骤1605。当单位时间切换次数大于该门限值时，下一步为步骤1606。
1605，确定两小区为稳定驻留的小区。
也就是说，当单位时间在两个小区之间切换次数小于或等于门限值时，表示终端设备在该两个小区之间稳定驻留，即在该两个小区不是乒乓小区。
1606，确定两小区之间频繁重选。
也就是说，当单位时间在两个小区之间切换次数大于门限值时，表示终端设备在该两个小区之间频繁重选，即该两个小区为乒乓小区。
1607，确定在当前驻留小区的选网策略。
示例性的，策略匹配模块1322可以根据在步骤1603至1606中的学习结果，确定适合当前驻留的小区的选网策略，即预测当前驻留小区的下一跳小区。这里，步骤1607可以为图2中的步骤206在固定场所下的一个具体示例。
作为一个示例，当步骤1602中，获取了在第一区域中驻留的一个小区时，可以直接将该小区作为终端设备在第一小区之后的下一跳小区。
当在步骤1602中，获取了在第一区域中驻留的至少两个小区时，可以执行图17所描述方法，来确定在当前驻留小区的选网策略。
图17示出了本申请实施例提供的一种网络选择的方法1700的示意性流程图。如图17所示，方法1700可以包括步骤1701至步骤1307。示例性的，步骤1301可以由环境感知单元1310执行，步骤1302至1305可以由策略交互单元1320(例如策略交互单元中的策略匹配模块1322)执行。
1701，确定当前服务的第一小区C。
例如，采集单元1311可以获取当前服务的第一小区的小区信息，例如获取modem140实时发送的小区信息。路线和场景识别模块1312根据该第一小区的小区信息，确定当前服务的第一小区，并确定终端设备当前处于固定场所场景，即第一小区的小区信息为固定场所中的小区信息。
1702，是否满足C∈(C1,C2,C3)？
作为一种实现方式，策略匹配模块1322可以根据第一小区的小区标识，在已有固定场所对应的小区标识列表中寻找第一小区的小区标识。这里，固定场所对应的小区标识列表即该固定场所包括的N个小区对应的小区标识列表。
以该N个小区为C1、C2、C3，小区标识列表为(C1,C2,C3)为例，当小区标识列表(C1,C2,C3)中存在第一小区的小区标识C时，则确定在该小区标识列表(C1,C2,C3)对应的固定场所中存在第一小区，即满足C∈(C1,C2,C3)。当小区标识列表(C1,C2,C3)中不存在第一小区的小区标识C时，则确定在该小区标识列表(C1,C2,C3)对应的固定场所中不存在第一小区，即不满足C∈(C1,C2,C3)。
当不满足C∈(C1,C2,C3)，即终端设备当前驻留的小区不属于(C1,C2,C3)时，执行1703。
作为示例，用户进入固定场所的区域范围之后，但是终端设备当前驻留的小区不是该固定场所中的频数最高的前3个(top3)小区，比如此时驻留的小区可能是该固定场所附近的一个小区，或者为该固定场所中的频数为第4的小区。此时，可以执行1703。
当满足C∈(C1,C2,C3)，即终端设备当前驻留的小区属于(C1,C2,C3)时，执行1704。
1703，将C1，C2，C3中的至少一个小区作为终端设备在第一区域中能够选择的小区。此时，终端设备在第一区域中能够选择的小区可以表示为(C1,C2,C3)。这样，可以使得终端设备快速切换到top3小区中的一个小区，并可以在该小区中稳定驻留。
作为一种实现方式，策略匹配模块1322可以按照终端设备在C1，C2，C3中驻留的时长排序的优先级顺序，向终端设备推荐在第一区域中选择的小区。
可选的，当终端设备当前驻留的小区C不属于(C1,C2,C3)时，由于历史记录中没有记录由小区C切换到C1或C2或C3时，在小区C中的信号接收功率，因此可以根据默认的起测门限对C1或C2或C3进行测量。示例性的，默认的起测门限可以为modem设置的对所有小区的起测门限。可选的，终端设备还可以根据默认的逃离门限，进行邻区测量，即当终端设备在任一小区中的信号接收功率小于该默认的逃离门限时，对所有的邻区进行小区测量。
1704，是否满足C～∈(C1,C2,C3)？
其中，C～表示与当前驻留的小区C具有乒乓关系的小区。也就是说，在单位时间内，终端设备在小区C和小区C～之间切换的次数大于预设值。
当满足C～∈(C1,C2,C3)，即C1,C2,C3中包括终端设备当前驻留的小区C，同时还存在与小区C具有乒乓关系的小区C～时，执行1705。当不满足C～∈(C1,C2,C3)，即C1,C2,C3中包括终端设备当前驻留的小区C，但是并不存在与小区C具有乒乓关系的小区C～时，执行1706。
1705，将(C1,C2,C3)-(C,C～)作为终端设备在第一区域中能够选择的小区。其中，(C1,C2,C3)-(C,C～)表示C1,C2,C3中除C,C～之外的小区。这样，可以使终端设备切换到没有与当前驻留小区有乒乓关系的小区中，能够确保终端设备稳定驻留在下一跳小区中。
可选的，还可以根据获取终端设备在小区之间多次切换时对应的多个在小区C中的信号接收功率，来确定在当前小区C中的测量策略。其中，该测量策略包括终端设备在小区C中的起测门限和/或逃离门限。
作为一种实现方式，当获取了终端设备多次由小区C切换至(C1,C2,C3)-(C,C～)时的多个信号接收功率时，可以将该多个信号接收功率中的最大信号接收功率作为起测门限，将该多个信号接收功率中的最小信号接收功率作为逃离门限。例如，当小区C为C1，C～为C2时，可以获取终端设备多次由C1切换至C3的多个在C1中的信号接收功率，并将其中的最大信号接收功率作为在小区C1中对小区C3的起测门限(即当在小区C1中的信号接收功率小于该最大接收功率时，对小区C3进行测量)，将其中的最小信号接收功率作为在小区C1中的逃离门限(即当在小区C1中的信号接收功率小区该最小信号接收功率时，对所有的邻区进行策略)。这种情况下，也可以称该起测门限为对应于小区C2的起测门限，称该逃离门限为对应于小区C2的逃离门限。
1706，将(C1,C2,C3)-C中的至少一个小区作为终端设备在第一区域中能够选择的小区。其中，(C1,C2,C3)-C表示C1,C2,C3中除C之外的小区。这样，可以使终端设备切换到没有与当前驻留小区有乒乓关系的小区中，能够确保终端设备稳定驻留在下一跳小区中。
可选的，还可以根据获取终端设备在小区之间多次切换时对应的多个在小区C中的信号接收功率，来确定在当前小区C中的测量策略。其中，该测量策略包括终端设备在小区C中的起测门限和逃离门限。
例如，当小区C为C1时，可以获取终端设备多次由C1切换至C2的多个在C1中的信号接收功率，并将其中的最大信号接收功率作为在小区C1中对小区C2的起测门限(即 当在小区C1中的信号接收功率小于该最大接收功率时，对小区C2进行测量)，将其中的最小信号接收功率作为在小区C1中的逃离门限(即当在小区C1中的信号接收功率小区该最小信号接收功率时，对所有的邻区进行策略)。另外，还可以获取终端设备多次由C1切换至C3的多个在C1中的信号接收功率，并将其中的最大信号接收功率作为在小区C1中对小区C3的起测门限(即当在小区C1中的信号接收功率小于该最大接收功率时，对小区C3进行测量)，将其中的最小信号接收功率作为在小区C1中的逃离门限(即当在小区C1中的信号接收功率小区该最小信号接收功率时，对所有的邻区进行策略)。此时，在小区C中对不同小区的起测门限可以不同，或者在小区C中对不同的小区逃离门限不同，因此这里的该起测门限可以为针对特定小区的起测门限，逃离门限可以为针对特定小区的逃离门限。
又例如，当获取了终端设备多次由小区C切换至(C1,C2,C3)-(C)时的多个信号接收功率时，可以将该多个信号接收功率中的最大信号接收功率作为起测门限，将最小信号接收功率最为逃离门限。例如，当小区C为C1时，可以获取终端设备多次由C1切换至C2或C3的多个在C1中的信号接收功率，并将其中的最大信号接收功率作为在小区C1中对小区C2或C3的起测门限，将其中的最小信号接收功率作为在小区C1中的逃离门限。此时，该起测门限可以为在小区C中的通用的起测门限，该逃离门限为在小区C中的通用逃离门限。
具体的，起测门限和逃离门限可以参见上文中的描述，为了简洁，这里不再赘述。
在一些可选的实施例中，可以预先配置起测门限或逃离门限，本申请实施例对此不做限定。
因此，本申请实施例通过获取终端设备在固定场所中小区驻留的历史记录，并根据终端设备在该固定场所中的小区中的历史驻留情况，预测终端设备当前在第一小区中的下一跳小区，使得终端设备可以根据预测的小区有针对性的进行搜网，从而有助于减少终端设备测量的邻区的数量，或者测量邻区的次数，或者进行小区重选的次数，进而有助于降低终端设备的功耗。
需要说明的是，对于固定场所的场景而言，当在确定终端设备当前驻留的第一小区之前，确定终端设备在上述N个小区中乒乓切换的小区时，能够使得终端设备在获取当前驻留的小区之后，更快速的预测出当前小区的下一跳小区。
可选的，在本申请实施例中，对于固定场所的场景而言，也可以在确定终端设备当前驻留的第一小区之后，再确定该N个小区中终端设备乒乓切换的小区。作为示例，当当前驻留的第一小区为C，且C∈(C1,C2,C3)时，在确定该N个小区中终端设备乒乓切换的小区的过程中，可以只确定终端设备是否在第一小区C与(C1,C2,C3)中除C之外的其他小区之间乒乓切换。也就是说，当此时不需要确定终端设备是否在C2和C3之间乒乓切换。这样，能够节省终端设备的计算所消耗的资源。
图18示出了本申请实施例提供的一种网络选择的方法1800的示意性流程图。示例性的，该方法1800可以由图1A、图1B、图1C中所示的终端设备执行。进一步的，该方法1800可以由图1C中该系统架构100中的选网主控单元130执行。该方法1800包括步骤1810和1860。
1810，获取第一信息，所述第一信息包括所述终端设备驻留的小区的小区信息。
1820，从所述小区信息中获取第一小区信息或第二小区信息，其中，所述第一小区信 息为所述终端设备在固定路线中驻留的小区的小区信息，所述第二小区信息为所述终端设备在固定场所中驻留的小区的小区信息；

1840，获取第二信息，所述第二信息包括所述终端设备当前驻留的第一小区的小区信息。
1850确定所述第一小区的小区信息为固定路线中的小区信息，或为固定场所中的小区信息。
1860，当所述第一小区的小区信息为固定路线中的小区信息，在所述第一有效驻留小区中确定第二小区，当所述第一小区的小区信息为固定场所中的小区信息时，在所述第二有效驻留小区中确定所述第二小区，其中，所述第二小区为所述终端设备在所述第一小区之后的下一个驻留小区。
因此，本申请实施例能够对终端设备驻留的小区的小区信息进行固定路线或固定场所分类，并根据预设规则对不同的分类进行不同的预处理，获取不同分类下终端设备的有效驻留小区，然后根据不同分类下的有效驻留小区，生成适用于该终端设备当前的选网策略，该选网策略用于指示终端设备在当前驻留的小区的下一跳小区，使得终端设备能够有针对性的进行网络搜索，从而有助于降低终端设备的功耗。
