具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
图1是根据本公开一个实施例示出的一种随机接入失败处理方法的示意流程图。本实施例所示的随机接入失败处理方法可以适用于用户设备，例如手机、平板电脑、可穿戴设备等电子设备。
如图1所示，所述随机接入失败处理方法可以包括以下步骤：
在步骤S1中，在向基站发送随机接入的前导码的次数大于预设次数时，确定发送所述前导码所使用的小区和载波；
在步骤S2中，在发送所述前导码所使用的小区为被配置了SUL载波(可以是一个SUL载波，也可以是多个SUL载波)和非SUL载波的主小区的情况下，若发送所述前导码所使用的载波为非SUL载波，通过所述SUL载波向所述基站传输随机接入存在问题的消息。
在一个实施例中，当用户设备向基站发起随机接入时，首先向基站发送随机接 入的前导码(preamble)，而当发送前导码的次数大于预设次数(可以根据进行设置，例如可以在基站侧进行设置并发送给用户设备，也可以在用户设备侧进行设置)，可以判定发起的随机接入失败。
若上述随机接入是用户设备通过主小区的非SUL载波发起的，那么可以确定主小区的非SUL载波存在问题，而由于主小区还被配置了SUL载波，并且SUL载波的性能一般优于非SUL载波的性能，在SUL载波存在问题的情况下，SUL载波可能并没有问题，因此可以通过SUL载波向基站传输随机接入存在问题的消息，以保证基站能够及时地接收到问题，进而及时地处理问题。
需要说明的是，无论发送所述前导码所使用的小区为主小区，主辅小区，还是主小区和主辅小区以外的小区，无论发送所述前导码所使用载波为SUL载波还是非SUL载波，当向基站发送随机接入的前导码的次数大于预设次数时，用户设备的MAC(介质访问控制)层可以向RRC(无限资源控制)层发送指示，以指示随机接入存在问题，并指示发送前导码所使用的小区以及载波。除了向RRC层发送指示，还可以向其他MAC层的上层发送指示，例如RLC(无线链路控制)层、PDCP(分组数据汇聚协议)层等。
图2是根据本公开一个实施例示出的一种通过SUL载波向基站传输随机接入存在问题的消息的示意流程图。如图2所示，在图1所示实施例的基础上，所述通过所述SUL载波向所述基站传输随机接入存在问题的消息包括：
在步骤S201中，确定通过所述SUL载波向所述基站传输随机接入存在问题的消息是否触发随机接入；
在步骤S202中，若未触发随机接入，通过所述SUL载波向所述基站传输随机接入存在问题的消息；
在步骤S203中，若触发了随机接入，通过所述SUL载波向所述基站发起随机接入；
在步骤S204中，在通过所述SUL载波向所述基站发起随机接入成功后，通过所述SUL载波向所述基站传输随机接入存在问题的消息。
在一个实施例中，当通过SUL载波向所述基站传输随机接入存在问题的消息时，可能会触发随机接入，例如检测到上行失步，或者检测到需要重建RRC(无线资源控制)连接可以触发随机接入，具体触发随机接入的情况除了上述两种，还存在其 他情况，在此不再赘述。
在一个实施例中，在通过SUL载波向所述基站传输随机接入存在问题的消息触发随机接入时，由于已经确定主小区的非SUL载波存在问题，因此可以通过主小区的SUL载波向基站发起随机接入，保证能够顺利地随机接入基站，进而顺利地将随机接入存在问题的消息传输至基站。
图3是根据本公开一个实施例示出的另一种随机接入失败处理方法的示意流程图。如图3所示，在图1所示实施例的基础上，所述方法还包括：
在步骤S3中，在通过所述SUL载波向所述基站传输随机接入存在问题的消息之前，确定在所述主小区上是否触发基于竞争的随机接入；
在步骤S4中，若触发基于竞争的随机接入，确定是否存在用于指示发起随机接入所使用的载波的消息；
在步骤S5中，若不存在，通过所述SUL载波向所述基站发起基于竞争的随机接入。
在一个实施例中，除了如图2所示的实施例中通过SUL载波向所述基站传输随机接入存在问题的消息可能在主小区上触发随机接入，在通过SUL载波向所述基站传输随机接入存在问题的消息之前，也可能在主小区上触发随机接入，例如检测到上行失步，或者检测到需要重建RRC连接可以触发随机接入，具体触发随机接入的情况除了上述两种，还存在其他情况，在此不再赘述。
在一个实施例中，若触发的随机接入，是基于竞争的随机接入，且不存在用于指示发起随机接入所使用的载波的消息，也即无法根据指示发起随机接入所使用的载波的消息确定选择非SUL载波发起基于竞争的随机接入，还是选择SUL载波发起基于竞争的随机接入，而由于SUL载波的性能(例如信号强度)一般优于非SUL载波，因此当用户设备未检测到用于指示发起随机接入所使用的载波的消息时，可以通过性能较好的SUL载波向基站发起基于竞争的随机接入，以提高竞争的成功率，进而提高随机接入的成功率。
图4是根据本公开一个实施例示出的又一种随机接入失败处理方法的示意流程图。如图4所示，在图3所示实施例的基础上，所述方法还包括：
在步骤S6中，若触发基于竞争的随机接入，确定是否接收到与发起随机接入时选择载波相关联的小区信号阈值；其中，与发起随机接入时选择载波相关联的小区 信号可以包括RSRP(Reference Signal Receiving Power，参考信号接收功率)，还可以包括RSRQ(Reference Signal Receiving Quality，参考信号接收质量)。
其中，所述若触发基于竞争的随机接入，确定是否存在用于指示发起随机接入所使用的载波的消息；以及若不存在，通过所述SUL载波向所述基站发起基于竞争的随机接入包括：
在步骤S401中，若接收到所述小区信号阈值，确定是否存在用于指示发起随机接入所使用的载波的消息；
在步骤S501中，若不存在，根据所述小区信号阈值确定通过所述SUL载波或所述非SUL载波向所述基站发起基于竞争的随机接入。
在一个实施例中，在确定接收到与发起随机接入时选择载波相关联的小区信号阈值的情况下，若不存在用于指示发起随机接入所使用的载波的消息，也即无法根据指示发起随机接入所使用的载波的消息确定选择非SUL载波发起基于竞争的随机接入，还是选择SUL载波发起基于竞争的随机接入，那么可以根据小区信号阈值确定通过所述SUL载波或所述非SUL载波向所述基站发起基于竞争的随机接入。例如以RSRP为例，若主小区的RSRP大于RSRP阈值，可以通过非SUL载波向基站发起基于竞争的随机接入，若主小区的RSRP小于或等于RSRP阈值，可以通过SUL载波向基站发起基于竞争的随机接入。
可选地，随机接入存在问题的消息为主小区组无线链路失败消息。
在一个实施例中，主小区组无线链路失败消息也即MCG RLF(Master Cell Group Radio Link Failure)，通过向基站发送主小区组无线链路失败消息，便于基站对随机接入问题的消息进行分类。
图5是根据本公开一个实施例示出的另一种通过SUL载波向基站传输随机接入存在问题的消息的示意流程图。如图5所示，在图1所示实施例的基础上，所述通过所述SUL载波向所述基站传输随机接入存在问题的消息包括：
在步骤S205中，通过所述SUL载波向基站传输预设字段，其中，所述预设字段与所述主小区组无线链路失败消息相关联。
在一个实施例中，可以通过与主小区组无线链路失败消息相关联的预设字段，向基站传输随机接入存在问题的消息，使得基站可以根据有预设字段确定接收到的随机接入存在问题的消息属于主小区组无线链路失败消息。
图6是根据本公开一个实施例示出的又一种通过SUL载波向基站传输随机接入存在问题的消息的示意流程图。如图6所示，在图1所示实施例的基础上，所述通过所述SUL载波向所述基站传输随机接入存在问题的消息包括：
在步骤S206中，通过所述SUL载波向所述基站传输的任一消息携带所述主小区组无线链路失败消息。
在一个实施例中，可以通过向基站传输的任一消息携带主小区组无线链路失败消息，据此，无需通过单独的字段来传输主小区组无线链路失败消息。
图7是根据本公开一个实施例示出的又一种随机接入失败处理方法的示意流程图。如图7所示，在图1所示实施例的基础上，所述方法还包括：
在步骤S7中，通过所述SUL载波向所述基站传输所述用户设备的主小区组中每个服务小区的测量信息。其中，测量信息可以包括RSRP，还可以包括RSRQ。
在一个实施例中，在确定非SUL载波存在问题的情况下，可以通过SUL载波向基站传输用户设备的主小区组中每个服务小区的测量信息，以便基站可以根据测量信息确定是否需要指示用户设备在主小区组的服务小区中切换小区。
图8是根据本公开一个实施例示出的又一种随机接入失败处理方法的示意流程图。如图8所示，在图1所示实施例的基础上，所述方法还包括：
在步骤S8中，通过所述SUL载波向所述基站传输所述主小区的邻小区中，信号强度最高的邻小区的测量信息。其中，测量信息可以包括RSRP，还可以包括RSRQ。
在一个实施例中，在确定非SUL载波存在问题的情况下，可以通过SUL载波向基站传输用户设备的主小区的邻小区中，信号强度最高的邻小区的测量信息，以便基站可以根据测量信息确定是否需要指示用户设备切换到主小区的邻小区中，信号强度最高的邻小区。
图9是根据本公开一个实施例示出的又一种随机接入失败处理方法的示意流程图。如图9所示，在图1所示实施例的基础上，所述方法还包括：
在步骤S9中，通过所述SUL载波向所述基站传输所述用户设备的辅小区组中每个服务小区的测量信息。其中，测量信息可以包括RSRP，还可以包括RSRQ。
在一个实施例中，在确定非SUL载波存在问题的情况下，可以通过SUL载波向基站传输用户设备的辅小区组中每个服务小区的测量信息，以便基站可以根据测量 信息确定是否需要指示在辅小区组的服务小区中切换小区。
图10是根据本公开一个实施例示出的又一种随机接入失败处理方法的示意流程图。如图10所示，在图1所示实施例的基础上，所述方法还包括：
在步骤S10中，通过所述SUL载波向所述基站传输所述辅小区的邻小区中，信号强度最高的邻小区的测量信息。其中，测量信息可以包括RSRP，还可以包括RSRQ。
在一个实施例中，在确定非SUL载波存在问题的情况下，可以通过SUL载波向基站传输用户设备的辅小区的邻小区中，信号强度最高的邻小区的测量信息，以便基站可以根据测量信息确定是否需要指示用户设备切换到辅小区的邻小区中，信号强度最高的邻小区。
可选地，所述随机接入存在问题的消息包括所述非SUL载波的信息。
在一个实施例中，在确定非SUL载波存在问题的情况下，可以将非SUL载波的信息包含于随机接入存在问题的消息传输至基站，以便基站可以快去确定用户设备的主小区的非SUL载波存在问题，进而进行适当的处理。
图11是根据本公开一个实施例示出的又一种通过SUL载波向基站传输随机接入存在问题的消息的示意流程图。如图11所示，在图1所示实施例的基础上，所述通过所述SUL载波向所述基站传输随机接入存在问题的消息包括：
在步骤S207中，确定第一预设定时器是否在运行，其中，所述第一预设定时器用于对连接重建流程进行计时；
在步骤S208中，若第一预设定时器未运行，通过所述SUL载波向所述基站传输随机接入存在问题的消息。
在一个实施例中，若第一预设定时器在运行，那么可以确定用户设备正处于与基站连接重建的流程中，由于连接重建流程结束后，即可与基站重新建立通信连接，在一定程度上解决非SUL载波存在的问题，因此无需向基站传输随机接入存在问题的消息。而若第一预设定时器未运行，则通过SUL载波向所述基站传输随机接入存在问题的消息，以便基站可以快速地处理。
图12是根据本公开一个实施例示出的又一种通过SUL载波向基站传输随机接入存在问题的消息的示意流程图。如图12所示，在图1所示实施例的基础上，所述通 过所述SUL载波向所述基站传输随机接入存在问题的消息包括：
在步骤S209中，根据预存信息确定向RRC层指示随机接入存在问题或不指示随机接入存在问题；
在步骤S210中，若根据预存信息确定向RRC层指示随机接入存在问题，通过所述SUL载波向所述基站传输随机接入存在问题的消息。
在一个实施例中，可以通过用户设备的MAC层向RRC层指示，其中，预存消息可以在基站侧配置，并由基站发送至用户设备，也可以在用户设备侧配置。
在一个实施例中，若通过非SUL载波发送前导码的次数大于预设次数，可以确定非SUL载波存在问题，而由于SUL载波的性能一般优于非SUL载波的性能，因此在非SUL载波存在问题的情况下，SUL载波不一定存在问题，也即在SUL载波不存在问题的情况下，用户设备仍可以通过主小区的SUL载波与基站进行通信。
因此，可以根据预存消息确定是否向RRC层指示随机接入存在问题，若不向RRC层指示随机接入存在问题，则无需通过SUL载波向基站传输随机接入存在问题的消息，而若向RRC层指示随机接入存在问题，则需通过SUL载波向基站传输随机接入存在问题的消息。
图13是根据本公开一个实施例示出的又一种随机接入失败处理方法的示意流程图。如图13所示，在图1所示实施例的基础上，所述方法还包括：
在步骤S11中，在发送所述前导码所使用的小区为被配置了SUL载波和非SUL载波的主小区的情况下，若发送所述前导码所使用的载波为SUL载波，向所述基站发起连接重建流程。
在一个实施例中，若发送前导码所使用的载波为SUL载波，由于SUL载波的性能一般优于非SUL载波的性能，在SUL载波存在问题的情况下，非SUL载波一定存在问题，也即在SUL载波存在问题的情况下，用户设备无法通过主小区的载波与基站进行通信，所以可以向基站发起连接重建流程，以便与基站通信建立通信连接，从而与基站进行通信。
图14是根据本公开一个实施例示出的一种向基站发起连接重建流程的示意流程图。如图14所示，在图13所示实施例的基础上，所述向所述基站发起连接重建流程包括：
在步骤S1101中，确定第二预设定时器是否在运行，其中，所述第二预设定时器用于对连接重建流程进行计时；
在步骤S1102中，若第二预设定时器未运行，向所述基站发起连接重建流程。
