具体实施方式
本发明实施例提供了一种针对独立组网弱覆盖的方法、终端设备及存储介质，用于在SA网络建设不完善时，能快速禁用问题小区或弱覆盖小区，减少由于网络问题带来的不良体验，保证用户能快速注册更好的小区，从而进行正 常的业务。
为了使本技术领域的人员更好地理解本发明方案，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描述，显然，所描述的实施例仅仅是本发明一部分的实施例，而不是全部的实施例。基于本发明中的实施例，都应当属于本发明保护的范围。
独立组网(standalone，SA)是5G时代重要的组网方式，也是未来的趋势，运营商白皮书明确要求厂商出货时需要支持SA能力。但是当前各大运营商在不同城市SA网络的建设进度是不一样，同一城市繁华的商业区和居民区建设水平也是良莠不齐，往往存在大量的SA弱覆盖地点，导致用户在使用过程中会遇到较多的问题，影响用户体验和产品口碑。
但是目前终端设备厂商都是遵循运营商需求，出货时直接带有SA能力。现有的SA能力缺少灵活控制，会遇到较多的问题。主要表现在SA网络注册不上，不能进行基本功能(如电话和上网)，甚至会带来一定功耗问题。这些都会给用户带来不好的体验，严重情况下会引起网络的投诉和退换机。
本发明提出一种针对SA弱覆盖的方法，这样终端设备可以能更快地注册上合适的小区，进行正常的业务需求，也能减少由于某些地区SA网络建设初期的引起的投诉问题，又能在一定程度上提高终端设备的表现力。

示例性的，第一定时器对应T1，第二定时器对应T2，第三定时器对应T3，T1可以为150ms，T2可以为300ms，T3可以为600ms。N的取值可以为3。针对SA弱覆盖的小区禁用策略，其针对的场景是RRC初始建立时，T1时间内出现N次low layer failure，将检测到的候选小区设为禁用状态，并开启第二定时器和第三定时器。即可以理解为终端设备检测到满足禁用状态的异常场景，启动bar cell时长T2和监控时长T3，且T3大于T2。
202、在所述第二定时器未超时的情况下，保持所述候选小区处于禁用状态。
所述在所述第二定时器未超时的情况下，保持所述候选小区处于禁用状态，可以包括：在所述第二定时器未超时，且所述终端设备处于空闲(idle)态或者连接(connect)态的情况下，所述终端设备保持所述候选小区处于禁用状态。
示例性的，如果T2未超时，在idle态和connect态下，终端设备都不会响应网络的事件，即该cell在T2未超时时一直被bar。
203、在所述第二定时器超时的情况下，将所述候选小区从所述禁用状态切换为非禁用状态。
可选的，所述终端设备将所述候选小区从所述禁用状态切换为非禁用状态之后，所述方法还包括：所述终端设备重新尝试接入所述非禁用状态的候选小区。
可选的，所述在所述第二定时器超时的情况下，所述终端设备将所述候选小区从所述禁用状态切换为非禁用状态，可以包括但不限于以下的实现方式：
方式1：在所述第二定时器超时，且所述第三定时器未超时的情况下，若检测到所述终端设备尝试接入所述非禁用状态的候选小区出现低层失败，则所述终端设备重新将所述非禁用状态的候选小区设为所述禁用状态，重置所述第二定时器和所述第三定时器。
可选的，若检测到所述终端设备尝试接入所述非禁用状态的候选小区出现低层失败，则所述终端设备重新将所述非禁用状态的候选小区设为所述禁用状态，重置所述第二定时器和所述第三定时器，可以包括：若检测到所述终端设备尝试接入所述非禁用状态的候选小区出现一次或多次低层失败，则所述终端 设备重新将所述非禁用状态的候选小区设为所述禁用状态，重置所述第二定时器和所述第三定时器。
示例性的，如果T2超时，T3未超时，此时终端设备在问题小区再发生一次low layer failure失败，则重新设为bar cell，重新计时T2和T3。
方式2：在所述第二定时器超时，且所述第三定时器超时的情况下，重启所述第一定时器，重新进行尝试接入所述候选小区。
可选的，所述终端设备重启所述第一定时器，重新进行尝试接入所述候选小区，可以包括：所述终端设备重启所述第一定时器，重新进行尝试接入所述候选小区，进行低层失败的检测。
示例性的，如果T2超时，T3超时，未在问题小区再发生一次low layer failure失败，则重新开始问题场景的判断。那么，可以重新尝试接入问题小区，检测是否出现低层失败等步骤。
可选的，所述方法还包括：在触发重新搜网的情况下，所述终端设备将所述候选小区从所述禁用状态切换为所述非禁用状态，尝试接入所述非禁用状态的候选小区。
可选的，重新搜网的场景可以包括：所述终端设备处于飞行模式或者切换网络模式的场景。
可选的，所述方法还包括：若所述终端设备将所述禁用状态的候选小区切换为所述非禁用状态，尝试接入所述非禁用状态的候选小区出现低层失败，且所述第二定时器未超时，则重新将所述非禁用状态的候选小区设为禁用状态，重新开启所述第二定时器和第三定时器。
可选的，若所述终端设备将所述禁用状态的候选小区切换为所述非禁用状态，尝试接入所述非禁用状态的候选小区一次，若出现低层失败，且所述第二定时器未超时，则重新将所述非禁用状态的候选小区设为禁用状态，重新开启所述第二定时器和第三定时器。
示例性的，当飞行模式或切换网络模式等操作触发了重新搜网时，允许终端设备重新尝试当前被bar的小区搜网一次，如果本次搜网仍然发生low layer failure且T2未超时，重新bar cell，重新计时T2和T3。
可选的，所述方法还包括：在所述终端设备重启后，清除所述第一定时器、所述第二定时器、所述第三定时器、计数器和所述禁用状态的候选小区的信息，所述计数器用于计数所述低层失败的次数。

在本申请实施例中，在第一定时器未超时的情况下，若检测到所述终端设备尝试接入候选小区出现N次低层失败，则将所述候选小区设为禁用状态，并开启第二定时器，所述N为正整数；在所述第二定时器未超时的情况下，保持所述候选小区处于禁用状态；在所述第二定时器超时的情况下，将所述候选小 区从所述禁用状态切换为非禁用状态。即在SA网络建设不完善时，能快速禁用问题小区或弱覆盖小区，减少由于网络问题带来的不良体验，保证用户能快速注册更好的小区，从而进行正常的业务。同时也可以减少由于SA问题引起网络投诉和市场退机。
可以针对low layer failure共享一个计数器(counter)计次，这样针对弱覆盖小区和问题小区能快速禁用掉；在本申请所提及的参数值，都可灵活自定义。本申请实施例可应用于RRC初始建立时的场景，也可以应用于重建和切换过程中触发的low layer failure场景，具体不做限定。

下面结合图4对手机的各个构成部件进行具体的介绍：
RF电路410可用于收发信息或通话过程中，信号的接收和发送，特别地，将基站的下行信息接收后，给处理器480处理；另外，将设计上行的数据发送给基站。通常，RF电路410包括但不限于天线、至少一个放大器、收发信机、耦合器、低噪声放大器(Low Noise Amplifier，LNA)、双工器等。此外，RF电路410还可以通过无线通信与网络和其他设备通信。上述无线通信可以使用任一通信标准或协议，包括但不限于全球移动通讯系统(Global System of Mobile communication，GSM)、通用分组无线服务(General Packet Radio Service，GPRS)、码分多址(Code Division Multiple Access，CDMA)、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)、长期演进(Long Term Evolution，LTE)、电子邮件、短消息服务(Short Messaging Service，SMS)等。
存储器420可用于存储软件程序以及模块，处理器480通过运行存储在存储器420的软件程序以及模块，从而执行手机的各种功能应用以及数据处理。存储器420可主要包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需的应用程序(比如声音播放功能、图像播放功能等)等；存储数据区可存储根据手机的使用所创建的数据(比如音频数据、电话本等)等。此外，存储器420可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件、闪存器件、或其他易失性固态存储器件。
输入单元430可用于接收输入的数字或字符信息，以及产生与手机的用户设置以及功能控制有关的键信号输入。具体地，输入单元430可包括触控面板431以及其他输入设备432。触控面板431，也称为触摸屏，可收集用户在其上或附近的触摸操作(比如用户使用手指、触笔等任何适合的物体或附件在触控面板431上或在触控面板431附近的操作)，并根据预先设定的程式驱动相应的连接装置。可选的，触控面板431可包括触摸检测装置和触摸控制器两个部分。其中，触摸检测装置检测用户的触摸方位，并检测触摸操作带来的信号，将信号传送给触摸控制器；触摸控制器从触摸检测装置上接收触摸信息，并将它转换成触点坐标，再送给处理器480，并能接收处理器480发来的命令并加 以执行。此外，可以采用电阻式、电容式、红外线以及表面声波等多种类型实现触控面板431。除了触控面板431，输入单元430还可以包括其他输入设备432。具体地，其他输入设备432可以包括但不限于物理键盘、功能键(比如音量控制按键、开关按键等)、轨迹球、鼠标、操作杆等中的一种或多种。

手机还可包括至少一种传感器450，比如光传感器、运动传感器以及其他传感器。具体地，光传感器可包括环境光传感器及接近传感器，其中，环境光传感器可根据环境光线的明暗来调节显示面板441的亮度，接近传感器可在手机移动到耳边时，关闭显示面板441和/或背光。作为运动传感器的一种，加速计传感器可检测各个方向上(一般为三轴)加速度的大小，静止时可检测出重力的大小及方向，可用于识别手机姿态的应用(比如横竖屏切换、相关游戏、磁力计姿态校准)、振动识别相关功能(比如计步器、敲击)等；至于手机还可配置的陀螺仪、气压计、湿度计、温度计、红外线传感器等其他传感器，在此不再赘述。

WiFi属于短距离无线传输技术，手机通过WiFi模块470可以帮助用户收发电子邮件、浏览网页和访问流式媒体等，它为用户提供了无线的宽带互联网访问。虽然图4示出了WiFi模块470，但是可以理解的是，其并不属于手机的必须构成，完全可以根据需要在不改变发明的本质的范围内而省略。
处理器480是手机的控制中心，利用各种接口和线路连接整个手机的各个部分，通过运行或执行存储在存储器420内的软件程序和/或模块，以及调用存储在存储器420内的数据，执行手机的各种功能和处理数据，从而对手机进行整体监控。可选的，处理器480可包括一个或多个处理单元；优选的，处理 器480可集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作系统、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器480中。
