具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
在相关技术中，对于新空口(New Radio，NR)移动通信系统(简称NR系统)，目前用户端(User Equipment，UE，也可称之为终端设备(Mobile Terminal)、移动用户设备等)的连接失败情况主要包括以下几种：(1)切换失败，比如在规定时间内未切换完成，举例来说定时器t304超时；(2)辅小区组(Secondary Cell Group，SCG)change(变换)失败，比如在规定时间内接入新的SCG没有完成，举例来说定时器t307超时；(3)无线链路失败(Radio Link Failure，RLF)。其中，对于定时器t304或定时器t307，UE在对应接收到切换命令或SCG change命令的时候启动定时器，以及在小区的随机接入过程完成的时候，UE停止该定时器。
其中，无线链路连接失败主要包括：(1)物理层失败，比如定时器t310超时；(2)媒体接入控制(Medium Access Control，MAC)层的随机接入失败，比如达到最大随机接入尝试次数；(3)无线链路控制(Radio Link Control，RLC)层达到最大重传次数指示，比如达到RLC层最大重传次数；(3)波束失败，比如波束恢复过程失败。
可选地，对于上述RLC层达到最大重传次数的无线链路连接失败情况，在相关技术中会在连接失败的时候需要触发连接重建过程，当UE发起连接重建过程时，UE会进行小区选择的过程，具体通过扫描所有的频点进行小区选择，并在找到一个合适的小区后，UE在该小区发起连接重建过程。而对其他连接失败情况，并未给出解决方案。
但是，由于非授权频段为共享频段，当UE在非授权频段进行上行发送时，若出现上行数据无法发送出去的情况，则会导致UE的连接无法工作。因此，需要一种方案，能够实现对小区连接失败的准确检测，并针对小区连接失败的情况进行处理，以自行进行连接的恢复，提高数据发送的可靠性。
以下结合附图，详细说明本公开各实施例提供的技术方案。
参见图1所示，本公开实施例提供一种小区连接失败的处理方法，应用 于终端设备。该方法包括：
S101：确定与目标服务小区是否连接失败。
可选的，终端设备可以根据网络侧设备配置或者协议约定的具体情况，进行与目标服务小区是否连接失败的检测。其中，目标服务小区的数量可以为一个或多个，可以为主小区、主辅小区和辅小区中的至少一个。
S103：在与目标服务小区连接失败的情况下，根据服务小区的相关信息进行连接失败处理，其中，相关信息包括小区数量和小区类型中的至少一个。
在本公开实施例中，对与目标服务小区是否连接失败进行检测，并在确定与目标服务小区连接失败的情况下，根据服务小区的相关信息进行相应的连接失败处理，具体的，可以根据服务小区的小区数量和小区类型中的至少一个进行连接失败处理。如此，通过实现小区连接失败的准确检测，并针对小区连接失败的情况，基于服务小区的具体相关信息确定适当的连接失败处理方式，以根据该连接失败处理方式进行及时且有效的处理，能够实现小区连接的自行恢复，从而提高数据发送的可靠性。
可以理解，在本公开实施例的小区连接失败的处理方法中，无需考虑小区连接失败的具体类型，在准确地确定与目标服务小区连接失败的情况下，即可以根据终端设备的服务小区的相关信息进行适当的连接失败处理。显然，相较于相关技术中仅能在达到RLC层最大重传次数时触发连接重建的方案，不仅可以实现对小区连接失败的准确检测，还可以针对小区连接失败时的具体情况进行及时且有效的连接失败处理，以实现连接的自行恢复，从而能够提高数据发送的可靠性。
可选的，上述确定与目标服务小区连接失败的情况，可以包括与目标服务小区对应的一个或多个频点连接失败的情况。
需要说明的是，上述服务小区的相关信息包括但不限于小区数量和小区类型中的至少一个。
可选的，在本公开实施例的小区连接失败的处理方法中，对于上述步骤S101可以通过不同的具体实施例实现，以通过多样化的检测方案确保实现对小区连接失败的准确检测。
下面结合具体的实施例详细说明与目标小区是否连接失败的检测方案。
具体实施例一
在该具体实施例中，上述步骤S101，可以具体执行为以下内容：
在第一预设时间窗口内，确定目标服务小区上的上行发送失败次数；
根据上行发送失败次数，确定与目标服务小区是否连接失败。
可以理解，在确定与目标服务小区是否连接失败时，可以通过统计一个时间窗口内目标服务小区上的上行发送失败次数，即对第一预设时间窗口内，目标服务小区上出现过的上行发送失败情况进行统计，并基于该第一预设时间窗口内的上行发送失败次数的量化统计结果，实现与目标服务小区是否连接失败的检测，高效且准确。
具体地，上述根据上行发送失败次数，确定与目标服务小区是否连接失败的技术方案，一方面可以具体执行为以下内容：
若上行发送失败次数大于或等于失败次数门限值，则确定与目标服务小区连接失败。
可以理解，通过将第一预设时间窗口内统计的上行发送失败次数直接与失败次数门限值进行大小比较，并在检测到上行发送失败次数达到或超出失败次数门限值时，确定与目标服务小区连接失败；其中，失败次数门限值可以为网络侧设备配置的值也可以为协议约定的值。
可选的，上述上行发送失败次数为连续进行多次上行发送且均失败的总数。
可以理解，将统计的目标服务小区上的上行发送失败次数，可选的确定为在第一预设时间窗口内，目标服务小区上连续进行多次上行发送且均失败的总数；也就是说，当在第一预设时间窗口内集中出现上行发送失败的情况时，才作为该第一预设时间窗口内对上行发送失败次数的有效统计结果。如此，有助于提高基于上行发送失败次数，确定与目标服务小区是否连接失败的检测结果的可靠性和稳定性。
举例来说，如图2所示，第一预设时间窗口的长度为从时刻t1到时刻t2的时长，比如可以根据网络侧设备配置或协议约定将第一预设时间窗口的长度取为100ms，则可以从时刻t1到时刻t2间，统计目标服务小区的上行发送失败次数。可选地，该上行发送失败次数为时刻t1到时刻t2间统计的目标服 务小区上连续上行发送失败的总数。
具体地，若在时刻t1到时刻t2间对应的时间窗口内，统计的上行发送失败次数为8，且失败次数门限值为6，则可以在该时间窗口内确定与目标服务小区连接失败。其中，上行发送失败次数8可以为该时间窗口内，目标服务小区上连续进行了8次上行发送且每次上行发送均失败的总数。
具体地，上述根据上行发送失败次数，确定与目标服务小区是否连接失败的技术方案，另一方面还可以具体执行为以下内容：
根据上行发送失败次数，确定上行发送失败概率；
若上行发送失败概率大于或等于失败概率门限值，则确定与目标服务小区连接失败。
可以理解，首先可以基于第一预设时间窗口内统计的上行失败次数确定该时间窗口内的上行发送失败概率，然后将上行发送失败概率与失败概率门限值进行大小比较，并在检测到上行发送失败概率达到或超出失败概率门限值时，确定与目标服务小区连接失败；其中，失败概率门限值可以为网络侧设备配置的值也可以为协议约定的值。
举例来说，参照图2，若在时刻t1到时刻t2间对应的时间窗口内，统计的目标服务小区上的上行发送失败次数为9，且目标服务小区上总的上行发送次数为10，则可以确定该时间窗口内的上行发送失败概率为90％，则在失败概率门限值为80％的情况下，可以确定在该时间窗口内与目标服务小区连接失败。该失败概率门限值可以取为100％。
具体实施例二
在本公开实施例的小区连接失败的处理方法中，除了根据上述具体实施例一中记载的相应内容，实现与目标服务小区是否连接失败的准确检测，在该具体实施例中，还可以将上述步骤S101，具体执行为以下内容：
若目标服务小区上的上行发送状态为第一预设状态，则将第一计数值加1；
若第一计数值大于或等于第一计数门限值，或在第一计数值大于或等于第一计数门限值后且上行发送失败定时器超时，则确定与目标服务小区连接失败。
可以理解，在确定与目标服务小区是否连接失败时，通过对目标服务小区上具体的上行发送状态进行统计，并基于该针对上行发送状态的量化统计结果，实现与目标服务小区是否连接失败的检测，高效且准确。
具体的，对目标服务小区上的第一预设状态进行量化统计，即每当目标服务小区上的上行发送状态为第一预设状态时，则将第一计数值加1，比如可以通过第一计数器统计第一预设状态出现的次数。
在一个具体的方面，可以将对目标服务小区上的第一预设状态的量化统计结果即第一计数值与第一计数门限值进行比较，并在检测到当前的第一计数值达到或超出该第一计数门限值的情况下，直接确定与目标服务小区连接失败。
可选的，在上述通过第一计数值对目标服务小区上的第一预设状态进行统计的过程中，还可以包括以下内容：
若目标服务小区上的上行发送状态为第二预设状态，则将第一计数值复位，并在目标服务小区上的上行发送状态为第一预设状态的情况下，将第一计数值加1。
可以理解，统计第一计数值的过程中，每当检测到目标服务小区上的上行发送状态为第一预设状态时，则对应的第一计数值加1，而每当检测到目标服务小区上的上行发送状态为第二预设状态时，则将之前统计的第一计数值复位到初始值(比如0)，之后检测到目标服务小区上的上行发送状态再次为第一预设状态时，重新对第一计数值进行统计。如此循环往复，直到判定第一计数值达到或超出第一计数门限值，也就是说，实现对目标服务小区上的上行发送状态连续为第一预设状态的量化结果统计。
可选的，在第一计数值大于或等于第一计数门限值后且在上行发送失败定时器超时前，若目标服务小区上的上行发送状态为第二预设状态的第二计数值大于或等于第二计数门限值，则执行复位第一计数值和停止上行发送失败定时器中的至少一个操作。
可以理解，在上述上行发送失败定时器运行过程中，对目标服务小区上的发送状态为第二预设状态的情况进行量化统计，即每当目标服务小区上的上行发送状态为第二预设状态时，则将第二计数值加1，比如可以通过第二 计数器统计第二预设状态出现的次数。可选地，可以将对目标服务小区上的第二预设状态的量化统计结果即第二计数值与第二计数门限值进行比较，并在检测到当前的第二计数值达到或超出该第二计数门限值的情况下，执行复位第一计数值的操作和/或执行停止上行发送失败定时器的操作，即此时可以确定与目标服务小区连接未失败。
可选的，上述第二计数值为目标服务小区上的上行发送状态连续为第二预设状态的总数。
可以理解，在上述上行发送失败定时器运行过程中，每当检测到目标服务小区上的上行发送状态为第二预设状态时，则对应的第二计数值加1，而每当检测到目标服务小区上的上行发送状态为第一预设状态时，则将之前统计的第二计数值复位到初始值(比如0)，之后检测到目标服务小区上的上行发送状态再次为第二预设状态时，重新对第二计数值进行统计。如此循环往复，直到判定第二计数值达到或超出第二计数门限值，也就是说，在上述上行发送失败定时器运行过程中，实现对目标服务小区上的上行发送状态连续为第二预设状态的量化结果统计。
在另一个具体的方面，可以将对目标服务小区上的第一预设状态的量化统计结果即第一计数值与第一计数门限值进行比较，并在检测到当前的第一计数值达到或超出该第一计数门限值后启动上行发送失败定时器，等待一段时间，在上行发送定时器的计时结果超时的情况下，再确定与目标服务小区连接失败。
可选的，在上述通过第一计数值对目标服务小区上的第一预设状态进行统计的过程中，还可以包括以下内容：
若目标服务小区上的上行发送状态为第二预设状态，则将第一计数值复位，并在目标服务小区上的上行发送状态为第一预设状态的情况下，将第一计数值加1。
可以理解，统计第一计数值的过程中，每当检测到目标服务小区上的上行发送状态为第一预设状态时，则对应的第一计数值加1，而每当检测到目标服务小区上的上行发送状态为第二预设状态时，则将之前统计的第一计数值复位到初始值(比如0)，之后检测到目标服务小区上的上行发送状态再次 为第一预设状态时，重新对第一计数值进行统计。如此循环往复，直到判定第一计数值达到或超出第一计数门限值，也就是说，实现对目标服务小区上的上行发送状态连续为第一预设状态的量化结果统计。
可选的，在第一计数值大于或等于第一计数门限值后且在上行发送失败定时器超时前，若目标服务小区上的上行发送状态为第二预设状态的第二计数值大于或等于第二计数门限值，则执行复位第一计数值和停止上行发送失败定时器中的至少一个操作。
可以理解，在上述上行发送失败定时器运行过程中，对目标服务小区上的发送状态为第二预设状态的情况进行量化统计，即每当目标服务小区上的上行发送状态为第二预设状态时，则将第二计数值加1，比如可以通过第二计数器统计第二预设状态出现的次数。可选地，可以将对目标服务小区上的第二预设状态的量化统计结果即第二计数值与第二计数门限值进行比较，并在检测到当前的第二计数值达到或超出该第二计数门限值的情况下，执行复位第一计数值的操作和/或执行停止上行发送失败定时器的操作，即此时可以确定与目标服务小区连接未失败。
可选的，上述第二计数值为目标服务小区上的上行发送状态连续为第二预设状态的总数。
可以理解，在上述上行发送失败定时器运行过程中，每当检测到目标服务小区上的上行发送状态为第二预设状态时，则对应的第二计数值加1，而每当检测到目标服务小区上的上行发送状态为第一预设状态时，则将之前统计的第二计数值复位到初始值(比如0)，之后检测到目标服务小区上的上行发送状态再次为第二预设状态时，重新对第二计数值进行统计。如此循环往复，直到判定第二计数值达到或超出第二计数门限值，也就是说，在上述上行发送失败定时器运行过程中，实现对目标服务小区上的上行发送状态连续为第二预设状态的量化结果统计。
可选的，上述第一计数门限值和上述第二计数门限值可以为网络侧设备配置的值也可以为协议约定的值。
可选的，上述第一预设状态和第二预设状态，可以通过一个时间窗口内的上行发送的具体情况进行描述，即在每个第二时间窗口内对目标服务小区 上的上行发送状态进行判断，并对多个第二时间窗口分别对应的多个上行发送状态进行统计，以基于统计结果，确定与目标服务小区是否连接失败。如此通过对多个时间窗口对应的多个上行发送状态的平滑统计，可以使失败检测结果更加可靠且准确。具体的：
第一预设状态包括以下至少一个：在第二预设时间窗口内，目标服务小区上的上行发送失败次数满足第一条件，和在第二预设时间窗口内，目标服务小区上的上行发送次数小于或等于上行发送次数门限值；
第二预设状态包括以下至少一个：在第二预设时间窗口内，目标服务小区上的上行发送成功次数满足第二条件，和在第二预设时间窗口内，目标服务小区上的上行发送次数小于或等于上行发送次数门限值。
可以理解，在每个第二预设时间窗口内对目标服务小区上判定的上行发送状态可以为上行发送失败、上行发送成功和没有上行发送中的一个。
其中，上行发送失败可以指在一个时间窗口内(即第二预设时间窗口)，在目标服务小区上的上行发送失败次数满足第一条件，比如若上行发送失败次数大于或等于对应的次数门限值(比如8次)，又比如若基于上行发送失败次数确定的上行发送失败概率大于或等于对应的概率门限值(比如90％或100％)，则可以认为该时间窗口内的上行发送失败次数满足第一条件。
上行发送成功可以指在一个时间窗口内(即第二预设时间窗口)，在目标服务小区上的上行发送成功次数满足第二条件，比如若上行发送成功次数大于或等于对应的次数门限值(比如8次)，又比如若基于上行发送成功次数确定的上行发送成功概率大于或等于对应的概率门限值(比如90％或100％)，则可以认为该时间窗口内的上行发送成功次数满足第二条件。
没有上行发送可以指一个时间窗口内(即第二预设时间窗口)，在目标服务小区上的上行发送次数小于或等于上行发送次数门限值(比如4次)。
需要说明的是，前述各个门限值，既可以为网络侧设备配置的值也可以为协议约定的值。
举例来说，如图3所示，包括两个第二预设时间窗口，其中，第一个第二预设时间窗口的长度为从时刻t1到时刻t2间的时长以及第二个第二预设时间窗口的长度为从时刻t2到时刻t3间的时长，比如可以根据网络侧设置配置 或协议约定将第二预设时间窗口的长度取为10ms，即从时刻t1到时刻t2间的时长为10ms以及从时刻t2到时刻t3间的时长为10ms，则可以对时刻t1到时刻t2间、时刻t2到时刻t3间，目标服务小区上的上行发送失败次数、上行发送成功次数和上行发送次数等进行统计。
若从时刻t1到时刻t2间对应的时间窗口内统计的上行失败次数满足第一条件，则该第二预设时间窗口对应的上行发送状态为上行发送失败；若从时刻t1到时刻t2间对应的时间窗口内统计的上行发送次数满足第二条件，则该第二预设时间窗口对应的上行发送状态为上行发送成功；以及若从时刻t2到时刻t3间对应的时间窗口内统计的上行发送次数未达到上行发送次数门限值，则该第二预设时间窗口对应的上行发送状态为没有上行发送。
可选地，没有上行发送既可以归为第一预设状态也可以归为第二预设状态，也就是说：第一预设状态包括上行发送失败和没有上行发送中的至少一个；第二预设状态包括上行发送成功和没有上行发送中的至少一个。
可以理解，导致目标服务小区上的上行发送失败的原因多种多样，比如由信道被占用(或处于繁忙状态)导致的也可能是由于终端设备本身的上行发送功率等参数受限而无法成功完成上行发送。在本公开实施例的小区连接失败的处理方法中，主要考虑目标服务小区上的上行发送失败是由信道被占用导致的情况。
具体的，目标服务小区上的上行发送失败是由信道被占用导致的，一方面可以包括在进行了上行信号发送后发现发送失败，继而确定是因为信道被占用所导致的；另一方面还可以包括在进行上行信号发送前先侦听信道是否被占用(即LBT)，若侦听到信道被占用则不进行上行信号的发送并直接确定上行发送失败，即在信道被占用的情况下，确定目标服务小区上的上行发送失败。
可选的，在本公开实施例的小区连接失败的处理方法中，对于上述步骤S103可以通过不同的具体实施例实现，以保证能够及时且准确地确定适当的连接失败处理方式。
下面结合具体的实施例详细说明根据服务小区的相关信息进行连接失败处理的技术方案。
具体实施例一
该具体实施例中，在上述相关信息为小区数量的情况下，上述步骤S103，可以具体包括以下内容：
在小区数量为一个的情况下，触发连接重建过程。
可以理解，在终端设备的服务小区只有目标服务小区一个时，在确定与该目标服务小区连接失败，则可以直接触发连接重建过程，以进行及时且有效的连接失败处理，从而实现小区连接的自行恢复，提高数据发送的可靠性。
具体实施例二
该具体实施例中，在上述相关信息为小区类型的情况下，上述步骤S103，还可以具体包括以下之中一种：
在目标服务小区为主小区组内的小区且终端设备与主小区组内的小区均连接失败，或目标服务小区为主小区的情况下，触发连接重建过程；
在目标服务小区为辅小区组内的小区且终端设备与辅小区组内的小区均连接失败，或目标服务小区为主小区组内的主小区，或目标服务小区为辅小区组内的主辅小区，或目标服务小区为主小区组内的辅小区，或目标服务小区为辅小区组内的辅小区的情况下，上报与目标服务小区连接失败相关的信息。
可以理解，终端设备的服务小区的小区类型可以多种多样，则可以在确定与目标服务小区连接失败的情况下，基于目标服务小区具体的小区类型确定适当的连接失败处理方式，以进行及时且有效的连接失败处理，从而实现小区连接的自行恢复，提高数据发送的可靠性。
举例来说，当终端设备工作在双连接(Dual Connectivity，DC)模式时，终端设备会被配置2个小区组，即主小区组(Master Cell Group，MCG)和辅小区组(Secondary Cell Group，SCG)。其中，MCG至少包括主小区(Primary Cell，PCell)，额外的MCG还可以包括一个或多个辅小区(Secondary Cell，SCell)，以及SCG至少包括主辅小区(Primary Secondary Cell，PSCell)，额外的SCG还可以包括一个或多个辅小区(Secondary Cell，SCell)。
那么一方面，在目标服务小区为主小区组内的小区且终端设备与该主小区组内的所有小区均连接失败的情况下，可以直接触发连接重建过程，以进 行及时且有效的连接失败处理，从而实现小区连接的自行恢复。
或者在目标服务小区为主小区的情况下，可以直接触发连接重建过程，以进行及时且有效的连接失败处理，从而实现小区连接的自行恢复。
另一方面，在目标服务小区为辅小区组内的小区且终端设备与辅小区组内的所有小区均连接失败的情况下，可以选择上报与目标服务小区连接失败相关的信息，以供网络侧设备参考进行配置的调整，从而实现小区连接的自行恢复。可选的，通过主小区组内的辅小区上报与目标服务小区连接失败相关的信息。
或者在目标服务小区为主小区组内的任一小区，即为主小区组内的主小区或为主小区组内的任一辅小区的情况下，可以选择上报与目标服务小区连接失败相关的信息，以供网络侧设备参考进行配置的调整，从而实现小区连接的自行恢复。
可选的，当目标服务小区为主小区时，可以通过主小区组或辅小区组内的辅小区上报与目标服务小区连接失败相关的信息；当目标服务小区为主小区组内的任一辅小区时，可以通过主小区组或辅小区组内其他未连接失败的小区上报与目标服务小区连接失败相关的信息。
或者在目标服务小区为辅小区组内的任一小区，即为辅小区组内的主辅小区或为辅小区组内的任一辅小区的情况下，可以选择上报与目标服务小区连接失败相关的信息，以供网络侧设备参考进行配置的调整，从而实现小区连接的自行恢复。可选的，当目标服务小区为主辅小区时，可以通过主小区组或辅小区组内的辅小区上报与目标服务小区连接失败相关的信息；当目标服务小区为辅小区组内的任一辅小区时，可以通过主小区组或辅小区组内其他未连接失败的小区上报与目标服务小区连接失败相关的信息。
可选的，在上述任一具体实施例中，上述触发连接重建过程，终端设备需要进行小区的重新选择，具体可以包括以下内容包括：
确定候选频点，候选频点不包括目标服务小区对应的频点或候选频点在预设时长内不包括目标服务小区对应的频点；
基于候选频点，触发连接重建过程。
可以理解，为了提高连接重建过程的效率，在确定用于连接重建的候选 频点时，可选的在确定已连接失败的目标服务小区对应的频点外的频点范围内进行确定。
可选地，考虑到上行发送失败的原因可能在一段时间后会结束，比如信道被占用的情况在一段时间会结束即信道会恢复空闲状态，则此时可以重新用于进行上行信号的发送，如此，为了进一步提高连接重建过程的效率，可以在更大的候选频点范围内进行连接重建，也就是说，可以仅在特定时段(即预设时长，比如30秒)内不将目标服务小区对应的频点作为候选频点。
其中，该预设时长的取值既可以为网络侧设备配置的值也可以为协议约定的值。可选的，在上述任一具体实施例中，若选择触发连接重建过程作为连接失败处理方式，则在上述触发连接重建过程中或在触发连接重建过程之后，该方法还可以包括：
上报与目标服务小区连接失败相关的信息。
可选的，在上述任一具体实施例中，上述上报给网络侧设备的与目标服务小区连接失败相关的信息包括以下至少一个：
小区连接失败的失败类型指示信息；
信道测量信息，信道测量信息包括接收信号强度指示、信道占用率和信道繁忙率中的至少一个。
可以理解，上述失败类型指示信息可以包括LBT失败指示信息，上述信道测量信息具体为信道繁忙相关的测量的信息。
需要说明的是，在本公开实施例中，上述与目标服务小区连接失败相关的信息包括但不限于上述失败类型指示信息和信道测量信息中的至少一个，以及信道测量信息包括但不限于上述接收信号强度指示(Received Signal Strength Indicator，RSSI)、信道占用率(Channel Occupancy Rate，CR)和信道繁忙率(Channel Busy Ratio，CBR)中的至少一个。
与图1中终端设备执行的小区连接失败的处理方法相对应的，本公开实施例还提供一种小区连接失败的处理方法，应用于网络侧设备。参见图4所示，该方法包括：
S201：配置与上行发送相关的配置信息，其中，配置信息包括连接失败检测信息和连接失败恢复信息中的至少一个。
S203：将配置信息发送至终端设备，以供终端设备基于配置信息确定与目标服务小区是否连接失败，并使得终端设备在与目标服务小区连接失败的情况下，根据服务小区的相关信息进行连接失败处理，其中，相关信息包括小区数量和小区类型中的至少一个。
在本公开实施例中，通过为终端设备配置与上行发送相关的配置信息，以供终端设备基于该包括连接失败检测信息和连接失败恢复信息中的至少一个的配置信息，对与目标服务小区是否连接失败进行检测，并在确定与目标服务小区连接失败的情况下，根据服务小区的相关信息进行相应的连接失败处理，具体的，至少可以根据服务小区的小区数量和小区类型中的一个进行连接失败处理。如此，通过为终端设备配置与上行发送相关的配置信息，可以使终端设备实现小区连接失败的准确检测，并针对小区连接失败的情况，基于服务小区的具体相关信息确定适当的连接失败处理方式，以根据该连接失败处理方式进行及时且有效的处理，从而实现小区连接的自行恢复，提高数据发送的可靠性。
需要说明的是，上述与上行发送相关的配置信息包括但不限于连接失败检测信息和连接失败恢复信息中的至少一个。
可选的，在本公开实施例的小区连接失败的处理方法中，在上述配置信息包括连接失败检测信息的情况下，连接失败检测信息包括但不限于以下至少一个：
第一预设时间窗口的时长，第一预设时间窗口用于确定目标服务小区上的上行发送失败次数；
失败次数门限值，用于与上行发送失败次数进行大小比较；
失败概率门限值，用于与基于上行发送失败次数确定的上行发送失败概率进行大小比较；
第二预设时间窗口的时长，第二预设时间窗口用于确定目标服务小区上的上行发送状态；
第一计数门限值，用于与上行发送状态为第一预设状态的第一计数值进行大小比较；
第二计数门限值，用于与上行发送状态为第二预设状态的第二计数值进 行大小比较；
上行发送失败定时器的定时门限值，定时门限值用于供终端设备确定上行发送失败定时器是否超时。
可以理解，通过为终端设备配置上述连接失败检测信息，达到提高小区连接失败检测的效率和准确性的目的。
具体的，终端设备可以根据在第一预设时间窗口内确定的上行发送失败次数实现小区连接是否失败的检测，可以在确定上行发送失败次数大于或等于失败次数门限值的情况下，或者在基于上行发送失败次数确定的上行发送失败概率大于或等于失败概率门限值的情况下，确定与目标服务小区连接失败。
另外，终端设备还可以根据对每个第二预设时间窗口对应的目标服务小区上的上行发送状态的统计情况实现小区连接是否失败的检测，可以在确定对第一预设状态的第一计数值大于或等于第一计数门限值的情况下，直接确定与目标服务小区连接失败，也可以在确定对第一预设状态的第一计数值大于或等于第一计数门限值后且上行发送失败定时器的计时值超过定时门限值的情况下，确定与目标服务小区连接失败，同时还可以考虑上行发送状态统计过程中，与第一预设状态不同的第二预设状态的出现情况，进行更加准确且稳定的小区连接失败检测。
可选的，在本公开实施例的小区连接失败的处理方法中，第一预设状态包括以下至少一个：在第二预设时间窗口内，目标服务小区上的上行发送失败次数满足第一条件，和在第二预设时间窗口内，目标服务小区上的上行发送次数小于或等于上行发送次数门限值；
第二预设状态包括以下至少一个：在第二预设时间窗口内，目标服务小区上的上行发送成功次数满足第二条件，和在第二预设时间窗口内，目标服务小区上的上行发送次数小于或等于上行发送次数门限值。
可选的，上述连接失败检测信息至少还包括该上行发送次数门限值。
可选的，在本公开实施例的小区连接失败的处理方法中，在上述配置信息包括连接失败恢复信息的情况下，连接失败恢复信息包括但不限于：
用于连接重建过程的候选频点不包括目标服务小区对应的频点的时长。
可以理解，通过为终端设备配置连接失败恢复信息，可以达到提高小区连接重建过程的效率，以使终端设备在更大的候选频点范围内进行连接重建，也就是说，可以仅在特定时段(即预设时长，比如30秒)内使终端设备不将目标服务小区对应的频点作为候选频点。也就是说，考虑到导致上行发送失败的原因可能会在一段时间后会结束，比如信道被占用的情况在一段时间会结束即信道会恢复空闲状态，则此时可以重新用于进行上行信号的发送。
可选的，在本公开实施例的小区连接失败的处理方法中，还可以包括以下内容：
