为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
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清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
参见图1，为本发明实施例提供的一种网络通信功能异常的处理方法的流程示意图，在本发明实施例中，所述方法包括步骤：
S101，调制解调器发送网络通信功能异常的指示信息给应用处理器。
S102，应用处理器获取调制解调器的网络通信功能异常的指示信息，并根据所述指示信息确定所述调制解调器的网络通信功能异常。
在一些可行的实施方式中，本发明实施例提供的网络通信功能异常的处理方法的执行主体可为应用处理器(英文：Application Processor，简称AP)和调制解调器，即应用处理器和调制解调器协作完成。其中，上述AP用于在低功耗CPU的基础上扩展音视频功能和专用接口的超大规模集成电路，是智能手机中的重要部件。AP和基带处理器(或称基带芯片)可以是独立的两个芯片，基带芯片中包含调制解调器等多个模块。AP和基带处理器也可以是集成在一起的一个芯片，具体可根据实际应用场景确定，在此不做限制。调制解调器用于将基带信号转换为射频信号、将射频信号转换为基带信号、处理接入层(AS)和非接入层(NAS)的信令、以及与AP进行接口等。
在一些可行的实施方式中，调制解调器支持多种协议栈。调制解调器出现异常时，AP可指示调制解调器通过调制解调器支持的多种协议栈进行网络注册，以恢复通信功能。当调制解调器检测到发生网络通信功能异常(如死机/assert)之后，调制解调器会发生崩溃(英文：crash/dump)，例如上/下行信道解调循环冗余校验(英文：Cyclic Redundancy Check,CRC) 高概率失败等。调制解调器无法正常进行数据处理，导致用户不能上网和打电话等。为了恢复正常网络，调制解调器发生崩溃时，可向AP发送网络通信功能异常的指示信息，通过上述指示信息告知AP其网络通信功能异常，以通过AP对其进行修复。AP接收到调制解调器的网络通信功能异常的指示信息之后，可确定调制解调器的网络通信功能发生了异常状态。进一步的，AP可对调制解调器的网络通信功能异常的原因进行检测，进而可根据具体原因进行调制解调器的网络修复。
在一些可行的实施方式中，调制解调器处理网络功能异常的原因可包括协议栈死机或者协议栈状态异常等，在此不做限制。
在一些可行的实施方式中，协议栈表示某个通信制式对应的多种协议的总和，例如协议栈包括全球移动通信系统(Global System for Mobile Communication，简称GSM)协议栈、增强型数据速率GSM演进技术(Enhanced Data Rate for GSM Evolution，简称EDGE)协议栈、高速下行分组接入技术(High Speed Downlink Packet Access，简称HSPDA)协议栈、时分同步的码分多址技术(Time Division-Synchronous Code Division Multiple Access，简称TD-SCDMA)协议栈、时分双工长期演进LTE(Time-Division Duplex Long Term Evolution，简称TDD-LTE)协议栈、频分双工长期演进(Frequency-Division Duplex，简称FDD-LTE)协议栈等。各个通信制式协议栈下面又包括多个子协议栈，例如TD-LTE协议栈又包括物理层协议栈、介质访问控制层(Media Access Control，简称MAC)协议栈、无线链路控制(Radio Link Control，简称RLC)协议栈、无线资源控制(Radio Resource Contro，简称RRC)协议栈和网络附属存储(Network Attached Storage，简称NAS)协议栈等，此处不再赘述。
具体的，默认协议栈为调制解调器支持的多个协议栈中的一个，是预先设置的协议栈，此处可以针对所有地区设置同一个默认的协议栈作为调制解调器初始选择使用的协议栈，也可以针对单个地区或处于某一区域的多个地区分别设置不同的默认协议栈，本发明实施例不作任何限定。
具体实现中，一种可行的实施方式在于：可以预置调制解调器的各个协议栈的优先级别。例如：可以在调制解调器出厂时即设置各个协议栈的优先级别；或者，可以在调制解调器被配置于移动终端内并进行初始化的过程中，按照移动终端使用各个协议栈时的网络连接及网络信号强度情况设置优先级别；等等。另一种可行的实施方式在于：可以灵活调整调制解调器的各个协议栈的优先级别，例如：可以依据移动终端在某个位置区域使用各 个协议栈时的网络连接及网络信号强度情况设置优先级别；或者，可以按照移动终端的常用网络制式的顺序设置各个协议栈的优先级别；等待。
需要说明的是，某个协议栈的优先级别越高，说明移动终端基于该协议栈可以获得更好的网络连接或更强的网络信号。调制解调器中优先级别最高的协议栈通常被称为默认协议栈，而调制解调器通常也是按照优先级别从高至低的顺序使用各个协议栈实现移动终端的网络注册及网络使用的。
在一些可行的实施方式中，协议栈在运行过程中会检查通信协议中的信令参数和参数组合，不同的网络或小区中对这些参数的配置不同。当某个小区或网络配置的参数超出协议栈支持的参数时，会导致协议栈死机。因此，AP可判断调制解调器当前所在小区或当前所接网络的网络参数中是否包括当前使用的协议栈不支持的网络参数。若判断为是，则可能是当前使用的协议栈死机造成的异常。此外，一些协议栈未能预先检测的内存错误、或者协议栈本身的漏洞也可能引起协议栈死机。其中常见的内存错误可包括内存泄漏、内存越界访问、引用野指针、访问未初始化的变量、栈溢出、字节对齐问题等。
在一些可行的实施方式中，调制解调器出现协议栈死机之后将无法自行进行网络修复，需要AP协助实现调制解调器的网络通信功能的修复。调制解调器出现协议栈死机之后可向AP发送指示信息，通过上述指示信息告知AP其网络通信功能异常。进一步的，也可由AP自行对调制解调器的网络通信功能的状态进行检测。若AP检测得到调制解调器处于协议栈死机状态，则可确定调制解调器的网络通信功能异常。
在一些可行的实施方式中，协议栈状态异常指的是在通信过程中对当前的状态上下文的检测结果与预先期望的结果不相符合。比如，当检测到一段时间内只有上行数据包，而没有任何下行数据包时则可确定为协议栈状态异常(即上下行链路不通)。或者，用户终端(User Equipment，简称UE)智能算法根据状态异常的现象判断出协议栈运行出现了异常。或者，UE与网络侧设备的通信过程受到不确定因素的影响而出现失步的情况；等等。当调制解调器检测到协议栈状态异常之后，调制解调器会发生崩溃，无法正常进行数据处理，导致UE不能上网。
调制解调器出现协议栈异常之后会发生崩溃，进而无法正常进行数据处理，也无法自行进行网络修复，需要AP协助实现调制解调器的网络通信功能的修复，可增强调制解调器的网络通信功能修复的可操作性。调制解调器出现协议栈异常之后可向AP发送指示信息，通过上述指示信息告知AP其网络通信功能异常。进一步的，也可由AP自行对调制解 调器的网络通信功能的状态进行检测。若AP检测得到调制解调器处于协议栈异常状态，则可确定调制解调器的网络通信功能异常。
S103，调制解调器断开与当前小区的网络连接。
S104，应用处理器将所述当前小区的接入优先级设定为第二优先级。
S105，应用处理器更新小区接入优先级列表到所述调制解调器。
S106，调制解调器接收所述应用处理器发送的小区接入优先级列表。
在一些可行的实施方式中，AP确定调制解调器的网络通信功能异常之后，则可控制调制解调器断开与当前小区的网络连接，以触发调制解调器重新搜索小区网络并建立调制解调器与新小区网络的连接，可避免当前小区的网络通信异常给调制解调器的网络通信功能带来影响。调制解调器可根据AP的指示断开与当前小区的网络连接。进一步的，AP控制调制解调器断开与当前小区的网络连接之后，还可将当前小区的接入优先级设定为较低优先级的第二优先级。AP设定了当前小区的接入优先级为第二优先级之后，可将小区接入优先级信息更新至调制解调器，以触发调制解调器重新搜索网络。其中，上述小区接入优先级信息包括多个小区中每个小区的接入优先级，即，包括上述当前小区的接入优先级。具体实现中，AP可预先生成一个用于记录小区接入优先级信息的小区接入优先级列表。AP可将设置为第二优先级的小区保存到上述小区接入优先级列表，预存在上述小区接入优先级列表中的小区则默认为第一优先级的小区。其中，第一优先级高于第二优先级，即，接入优先级为第一优先级的小区优先接入，接入优先级为第二优先级的小区次之。具体实现中，各个小区的默认接入优先级可为第一优先级。AP可通过更新小区接入优先级列表至调制解调器的方式触发调制解调器重新搜网。其中，上述当前小区的接入优先级为当前小区与调制解调器建立网络连接的优先级。例如，当调制解调器搜索到的网络包括小区1和小区2等多个小区的多个网络时。接入优先级较高的小区可优先建立与调制解调器的网络连接，AP设定各个小区的接入优先级可更好地避免多个小区与调制解调器建立网络连接时存在的网络连接竞争。设置当前小区的接入优先级为较低优先级，也可避免当前小区出现网络通信异常时影响调制解调器的网络恢复。具体实现中，调制解调器支持的RAT对应的小区中还包括接入优先级为第一优先级的小区，其中，第一优先级高于第二优先级。AP将当前小区的接入优先级设定为第二优先级，可避免调制解调器重新搜索网络时反复尝试建立与当前小区的网络连接，进而可避免调制解调器反复出现网络通信功能异常，节省功耗。
S107，调制解调器搜索其所支持的无线接入技术RAT对应的小区。
S108，调制解调器按照搜索得到的至少一个目标小区中各个目标小区的接入优先级选择指定小区，并建立与所述指定小区的网络连接。
在一些可行的实施方式中，AP控制调制解调器断开与当前小区的网络连接之后，则调制解调器可重新搜索调制解调器可接入的网络。具体实现中，调制解调器重新搜索的网络可包括接入优先级为第一优先级的第一小区和接入优先级为第二优先级的第二小区，其中，上述第二小区中包括上述断开与调制解调器的连接的当前小区。上述第一优先级和第二优先级仅是示例，具体还可包括更多级别的优先级，例如第三优先级、第四优先级等。其中，上述第一小区和第二小区也仅是代表示例，指代两种接入优先级的小区，并非只是两个小区，具体可根据实际应用场景设定更多级别的优先级对应的更多小区，在此不做限制。
具体实现中，调制解调器搜索调制解调器支持的RAT对应的小区服务。此时，由于调制解调器出现网络通信异常时接入的网络已经被AP设定为第二优先级的小区，其接入优先级低于其他第一优先级的小区，因此调制解调器重新搜网时上述当前小区不作为优先接入的小区，可避免调制解调器立即接入上述当前小区，进而避免调制解调器反复出现相同的网络通讯功能异常故障。
在一些可行的实施方式中，若调制解调器搜索得到的调制解调器支持的RAT对应的目标小区有多个，调制解调器可建立与每个目标小区的网络连接。此时，调制解调器根据每个小区的接入优先级选择优先接入的指定小区。具体的，调制解调器按照搜索得到的多个目标小区中各个目标小区的接入优先级，将接入优先级最高的小区确定为指定小区。调制解调器确定了接入优先级最高的指定小区之后，则可建立调制解调器与指定小区的网络连接，通过指定小区实行调制解调器的网络通信。调制解调器建立与指定小区的通信连接，可快速恢复调制解调器的网络通信功能。
进一步的，在一些可行的实施方式中，若调制解调器出现异常或者死机之后需要通过复位才能彻底恢复正常，则AP可控制调制解调器进行复位之后再调制解调器重新搜索小区网络，或者整机重启。进而调制解调器可在调制解调器搜索得到目标小区时，从目标小区中选择指定小区，建立与指定小区的网络连接。
在一些可行的实施方式中，若调制解调器搜索不到其所支持的RAT对应的目标小区，调制解调器可重启，通过重启恢复调制解调器的网络通信功能，操作简单，网络通信功能的恢复效率高。
在本发明实施例中，当应用处理器确定调制解调器的网络通信功能出现异常时，可控 制调制解调器断开与当前小区的网络连接，并将当前小区的接入优先级设定为较低优先级，以避免控制调制解调器反复尝试建立调制解调器与当前小区的通信连接而消耗网络连接资源。进一步的，调制解调器重新搜索调制解调器支持的无线接入技术对应的其他小区，从其他小区中选择接入优先级较高的指定小区，建立调制解调器与指定小区的通信连接，恢复调制解调器的网络通信功能，提高了网络通信功能恢复的效率。
参见图2，为本发明实施例提供的一种网络通信功能异常的处理方法的另一流程示意图，在本发明实施例中，所述方法包括步骤：
S201，应用处理器获取调制解调器的网络通信功能异常的指示信息，并根据所述指示信息确定所述调制解调器的网络通信功能异常。

S202，应用处理器控制所述调制解调器断开与当前小区的网络连接，并将所述当前小区的接入优先级设定为第二优先级。
S203，应用处理器更新所述当前小区的接入优先级到所述调制解调器。
在一些可行的实施方式中，AP在调制解调器的网络通信功能异常时，控制调制解调器断开调制解调器与当前小区的网络连接，以及更新当前小区的接入优先级到调制解调器的具体实现方式可参见上述实施例中的步骤S102和S103，在此不再赘述。
进一步的，在一些可行的实施方式中，AP也可预先设定调制解调器的网络通信功能的监测时长。若在该监测时长内，若检测得到调制解调器多次出现网络通信功能异常，则可控制调制解调器断开与当前小区的网络连接。AP在监测时长内调制解调器多次出现网络通信功能异常的情况下，再控制调制解调器断开与当前小区的网络连接，可避免在其他因素导致调制解调器的网络通信功能异常的情况下，将当前小区错误地设定为较低接入优先级的小区，影响调制解调器的网络通信功能的恢复。
在一些可行的实施方式中，AP可预先建立一个小区信息列表并将该列表存储至指定存储空间(例如UE的非易失存储空间)中。AP控制调制解调器断开与当前小区的连接之后，可在上述小区信息列表中记录当前小区的标识信息和上述当前小区的接入优先级，以将上述当前小区的标识信息和接入优先级等信息存储至上述指定存储空间中。其中，上述当前 小区的标识信息可为当前小区的位置信息。上述位置信息表示移动通信网络中预先规划的逻辑位置的标识。上述位置信息可包括小区号(Cell Identity，CID)、位置区域码(location area code，LAC)以及跟踪区域码(Tracking area code，TAC)等，具体可根据实际应用场景需求确定，在此不做限制。
S204，调制解调器搜索所述调制解调器支持的RAT对应的小区。
在一些可行的实施方式中，上述AP控制调制解调器搜索调制解调器支持的小区网络的实现方式可参见上述实施例中的步骤S104，在此不再赘述。
S205，若所述调制解调器搜索得到所述调制解调器支持的RAT对应的至少一个目标小区，调制解调器按照所述至少一个目标小区中各个目标小区的接入优先级选择指定小区。
S206，调制解调器建立与所述指定小区的网络连接。
在一些可行的实施方式中，上述调制解调器搜索其支持的小区网络的实现方式可参见上述实施例中的步骤S107和S108，在此不再赘述。
在一些可行的实施方式中，调制解调器搜索得到目标小区并确定了指定小区之后，调制解调器可建立与指定小区的网络连接，以快速恢复调制解调器的网络通信功能，操作简单，提高了调制解调器的网络通信功能恢复效率。
S207，应用处理器判断网络通信功能异常的异常原因是否上报。
在一些可行的实施方式中，AP恢复调制解调器的网络连接之后，可根据网络功能异常的异常原因的上报记录确定本次网络通信功能异常的异常原因是否上报过。如果网络通信功能异常的异常原因上报过，继续执行S210，否则，执行S208。
S208，应用处理器获取所述网络通信功能异常的异常原因和日志。
在一些可行的实施方式中，上述网络通信功能异常的原因可参见上述实施例中步骤S101所描述的实现方式，在此不再赘述。上述日志表示调制解调器访问内存的操作信息，操作信息包括：操作指令、操作时间和返回结果等。
S209，应用处理器将所述异常原因、日志和所述调制解调器的当前位置信息上报给网络侧。
在一些可行的实施方式中，AP可将调制解调器的网络通信功能异常的异常原因、当前位置信息和日志上报给网络侧。具体的，AP可扫描周围的WiFi热点并与WiFi热点建立连接。AP可以在移动终端连接上WiFi热点的情况下，通过WiFi热点将上述信息上报给网络侧，以节省流量。进一步的，AP也可以将异常原因显示在移动终端的显示屏上，供用户进 行查看。
S2010，本次网络通信功能异常处理结束。
在本发明实施例中，当AP确定调制解调器的网络通信功能出现异常时，可在监测时长内调制解调器多次发生网络通信功能异常的情况下，控制调制解调器断开调制解调器与当前小区的网络连接，并将当前小区的接入优先级设定为较低优先级，即可避免由于其他问题导致调制解调器的网络通信功能异常时错误地将当前小区的接入优先级后移降低调制解调器的网络接入的选择多样性，又可避免在当前小区的服务异常时控制调制解调器反复尝试建立调制解调器与当前小区的通信连接而消耗资源。进一步的，调制解调器重新搜索调制解调器支持的无线接入技术对应的其他小区，从其他小区中选择接入优先级较高的指定小区，建立调制解调器与目标小区的通信连接，恢复调制解调器的网络通信功能，提高了网络通信功能恢复的效率。若搜索不到其他小区，则调制解调器可重启，以进一步保障调制解调器的网络通信功能，增强调制解调器的网络通信功能异常的恢复的灵活性。
