可以理解的是，终端设备中包括卡槽，该卡槽用于插入用户的用户识别模块(subscriber identity module，SIM)卡。终端设备中还包括与卡槽对应的调制解调器，用户识别模块卡可以通过调制解调器接入网络。
其中，调制解调器(modem)是一种网络接口设备，用于将数字信号转换为模拟信号，使其能够在移动通信网络上进行传输。
其中，用户识别模块卡可以通过调制解调器接入的网络可以为第五代移动通信技术(5th-generation mobile communication technology，5G)网络、第四代移动通信技术(4th-generation mobile communication technology，4G)、第三代移动通信技术(3rd-generation mobile communication technology，3G)、第二代移动通信技术(2-generation mobile communication technology，2G)中的一种或多种网络制式的网络。
并且，5G网络制式的网络可以为新空口(new radio，NR)网络，4G网络制式的网络可以为长期演进(long term evolution，LTE)网络，3G网络制式的网络可以为第三代无线通讯技术(wideband code division multiple access，WCDMA)网络，2G网络制式的网络可以为全球移动通讯系统(global system for mobile communications，GSM)网络。
图1示例性示出了本申请实施例适用的一种通信系统架构示意图，该通信系统可以包括终端设备100和基站200(网络设备)。
以终端设备100支持SIM卡1和SIM卡2为例，终端设备中还可包括两个调制解调器，分别为第一调制解调器(modem1)和第二调制解调器(modem2)。
SIM卡1可以通过modem1实现与基站200通信，来搜索网络并接入网络，SIM卡2可以通过modem2实现与基站200通信，来搜索网络并接入网络。
上述的modem1和modem2可以是终端设备100中的同一实体无线通信模块，这种情况下，SIM卡1和SIM卡2可共用该同一实体无线通信模块实现与基站200通信。
可选的，modem1和modem2也可以是终端设备100中的两个不同的实体无线通信模块，这种情况下，SIM卡1可通过实体的第一无线通信模块实现与基站200通信，SIM卡2可通过实体的第二无线通信模块实现与基站200通信。
由于终端设备在接入网络时，需要伴随数据链接的建立过程，数据链接建立完成后终端设备才能进行正常的数据传输与通信。
其中，终端设备在建立数据链接时，终端设备中的调制解调器(modem)需要分配一个资源标识，来标识此次数据链接的建立，在断开数据链接时，modem可释放该资源标识。
示例性地，在终端设备接入的网络为4G网络时，数据链接的建立过程为数据分组网络(packet data network，PDN)连接的建立过程，数据分组网络建立完成后终端设备才能进行数据传输与通信。
其中，数据分组网络也称为数据包网络，是一种分组交换的网络系统，用于与公网互联，为用户提供数据通道。
示例性地，在终端设备接入的网络为5G网络时，通过网络切片实现分离处理和数据传输，数据链接的建立过程为协议数据单元(protocol data unit，PDU)会话的建立过程，协议数据单元建立完成后终端设备才能进行数据传输与通信。
其中，协议数据单元也称为数据包单元，它是一个数据包的基本单位，是数据在网络中传输和处理的基本单元。
另外，资源标识分别与承载标识符(EPS Bearer ID，EBI)、分组交换会话标识符(packet-switched session Identity，PSI)一一对应。
EBI用于标识进化分组系统(evolved packet system，EPS)网络中的数据承载，是LTE网络的核心部分之一。在EPS网络中，每个数据承载都需要分配唯一的EBI。
PSI用于标识一个与PDN建立的连接。在移动网络中，每当建立一个PDN连接时，都需要分配一个唯一的PSI。PSI常与资源标识一起使用，在建立PDN连接时，资源标识和PSI通常会分别映射到数据承载的EBI和服务质量等级标识符(quality of service class Identifier，QCI)。
然而，待分配的资源标识的数量是预先设定的(例如，15个)，在一些情况下，modem异常，例如，modem无法获取到可用的资源标识，导致终端设备在下次接入网络时，无法建立新的数据链接，无法接入网络，用户难以正常使用网络，影响用户的使用体验。
例如，modem异常还可以至少包括以下情况：
1、modem与AP之间的数据通道出现阻塞；
2、其他一些modem内部处理异常无法自行恢复。
面对上述问题，本申请可提供一种数据业务恢复方法、终端设备、芯片系统、计算机可读存储介质以及计算机程序产品，在确定调制解调器无法获取待分配的资源标识时，调制解调器可将无法获取待分配的资源标识的异常信息反馈到应用处理器，应用处理器响应于该异常信息可调用调制解调器向应用处理器提供的重启接口，触发调制解调器重启，来使得待分配的资源标识恢复到预设数量，便于调制解调器能够为下一次接入网络时分配资源标识，保证了数据业务能够尽快恢复，提高了用户的使用体验。
其中，上述的数据业务恢复方法应用于终端设备，终端设备可以为具有显示屏硬件以及相应软件支持的终端设备。
例如，终端设备可以为手机、平板电脑、车载设备、笔记本电脑、可穿戴设备、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本、个人数字助理(personal digital assistant，PDA)、智能汽车、智能电视、机器人等设备。

请参考图3，为本申请实施例提供的一种终端设备的软件系统与调制解调器的关系示意图。本申请实施例提供的数据业务恢复方法应用于图2所示的终端设备100时，终端设备100中的软件系统可以划分为如图3所示的应用程序层201、应用程序框架层202、硬件抽象层(hardware abstraction layer，HAL)203、无线接口层(radio interface layer,RIL)204，以及驱动层205。其中，应用处理器(application processor，AP)是整个软件系统的核心，在前述不同的软件层次之间扮演链接和协调的角色。

基于前述描述，结合图4，详细介绍终端设备实现本申请实施例的数据业务恢复方法的人机交互界面示意图。
为了便于说明，图4中，以终端设备为手机，手机的显示方向为竖屏方向为例进行示意。
请参阅图4，图4示出了本申请一实施例提供的人机交互界面示意图。
在接收到用户对图4所示的控件1001进行触发的操作后，手机的电话服务模块(telephony)可终端设备中的无线接口模块向终端设备中的调制解调器发送激活数据请求，若调制解调器无法获取待分配的资源标识，调制解调器可以确定调制解调器无法向网络设备发送数据链接请求，无法建立协议数据单元(protocol data unit，PDU)会话，进而无法接入网络。
其中，此处的无线接口模块为图3中的无线接口层。
基于此，调制解调器可通过无线接口模块向电话服务模块发送包括有用于指示调制解调器无法获取待分配的资源标识的激活数据响应消息，电话服务模块在接收到激活数据响应消息后，可通过无线接口模块向调制解调器发送重启请求，使得调制解调器在接收到重启请求后进行重启，调制解调器重启后，资源标识恢复到预设数量，如此，调制解调器可与网络设备执行网络注册过程，在网络注册后，向网络设备发送数据链接建立请求，调制解调器能够建立PDU会话，并为此次建立的PDU会话分配一个资源标识，由此，终端设备可以尽快接入网络，便于终端设备可以成功访问网络并与网络进行有效的通信。
下面，结合图5和图6，本申请以终端设备为例，结合附图和应用场景，对本申请实施例提供的数据业务恢复方法进行详细阐述。
下面，结合图5和图6，分别对本申请实施例提供的数据业务恢复方法的两种实现方式进行详细描述。
实现方式一
实现方式一适用于终端设备接入第四代移动通信技术网络制式(4G)网络，即LTE  attach(附着)场景。
示例性地，调制解调器(modem)在无法获取待分配的资源标识时，可通知应用处理器(application processor，AP)中的无线接口模块，由无线接口模块触发调制解调器重启，使得资源标识的数量重新达到预设数量，便于调制解调器能够恢复向网络设备发送网络附着请求来接入网络；如图5所示。
其中，此处的无线接口模块为图3中的无线接口层。
图5示出了本申请提供的一例数据业务恢复方法的流程示意图。如图5所示，该方法可以划分为两个不同的阶段，分别为1.1第一附着阶段和1.2第二附着阶段。
1.1第一附着阶段
其中，第一附着阶段可理解为由于调制解调器无法获取待分配的资源标识，调制解调器无法向网络设备发送附着请求的阶段；例如，如图5所示的S11。
S11、调制解调器无法获取待分配的资源标识。
终端设备接入网络时，需要先向网络设备发送附着请求，发送附着请求的过程需要伴随分组数据网络(packet data network，PDN)连接的建立过程。
其中，分组数据网络连接建立时，调制解调器需要分配一个资源标识，用于标识此次分组数据网络连接的建立的上下文信息；由于待分配的资源标识的数量为预设数量，在调制解调器内部出现异常的情况下，存在分配多个资源标识而没有释放的情况，使得调制解调器无法获取待分配的资源标识。
可以理解的是，调制解调器无法获取待分配的资源标识时，调制解调器无法向网络设备发送网络附着请求，无法建立分组数据网络连接，也无法接入网络。
在一些实施例中，待分配的资源标识的数量为预先设定的预设数量；例如，待分配的资源标识的数量取值范围为[0，14]，即待分配的资源标识的数量为15个。
应理解，上述以待分配的资源标识的数量为15个进行举例描述；本申请对待分配的资源标识的数量不做限定。
在一些实施例中，在调制解调器属于MTK芯片平台时，资源标识为上下文信息ID(context ID)。
1.2第二附着阶段

S12、调制解调器向无线接口模块发送异常状态消息。
其中，异常状态消息用于指示调制解调器无法获取待分配的资源标识。
另外，异常状态消息可以通过多种消息方式呈现。

在另一些实施例中，调制解调器可向无线接口模块发送非请求结果码(unsolicited result code,URC)，通过非请求结果码携带用于指示调制解调器无法获取待分配的资源标识的异常状态消息。
基于上述描述，调制解调器向无线接口模块发送用于指示调制解调器无法获取待分配的资源标识的异常状态消息，为无线接口模块触发调制解调器进行重启做好准备。
S13、无线接口模块对调制解调器发送异常状态消息进行解析处理。
可以理解的是，调制解调器通常可向无线接口模块发送多种类型的消息，因此，无线接口模块需要对调制解调器发送的消息进行解析处理，根据解析结果来确定调制解调器发送的消息属于哪一类型的消息。
由于当前调制解调器发送的消息为异常状态消息，无线接口模块对消息进行解析，可以确定该消息为用于指示调制解调器无法获取待分配的资源标识的异常状态消息，便于无线接口模块能够根据该异常状态消息触发调制解调器进行重启。
S14、无线接口模块向调制解调器发送重启请求。
其中，重启请求用于指示无线接口模块基于调制解调器向无线接口模块提供的重启接口，请求调制解调器进行重启。

S16、调制解调器对调制解调器进行重启。
基于S14，调制解调器可接收到重启请求，从而，调制解调器可以基于该重启请求进行重启。
可以理解的是，调制解调器重启，可使得资源标识全部释放，调制解调器重启后，资源标识的数量可重新达到预设数量。
可以理解的是，调制解调器进行重启，可使得资源标识全部释放，并恢复到预设数量。
其中，S15和S16在时序上不分先后，调制解调器可顺序执行S15和S16，也可同时执行S15和S16。
S17、调制解调器向网络设备发送附着请求。
基于S16，调制解调器重启后，资源标识的数量重新达到预设数量，调制解调器可以向网络设备发送网络附着请求，也可以重新建立数据分组网络(packet data network，PDN)连接。
其中，附着请求用于通过移动通信网络(如4G LTE等)请求连接到网络设备，并获取该网络设备提供的资源和服务。
在一些实施例中，网络设备在接收到附着请求后，可向调制解调器返回附着确认消息，用于指示网络设备接受调制解调器的附着，由此，调制解调器可基于第一网络制式的网络附着到网络设备，调制解调器可向网络设备发送附着完成消息，以使得终端设备接入网络，便于终端设备进行正常的数据传输与通信。
在一些实施例中，第一网络制式的网络为第四代移动通信技术网络制式下的网络，即4G LTE。
可以理解的是，由于调制解调器重启后，资源标识的数量重新达到预设数量，那么，调制解调器向网络设备发送附着请求的过程中，能够伴随PDN连接的建立过程，调制解调器能够分配一个资源标识，用来标识此次PDN连接的建立。
本申请中，在调制解调器无法获取待分配的资源标识时，终端设备中的调制解调器可以确定调制解调器无法向网络设备发送网络附着请求，无法建立分组数据网络连接，也无法接入网络；从而，终端设备中的调制解调器可向无线接口模块发送用于指示调制解调器无法获取待分配的资源标识的异常状态消息，为无线接口模块触发调制解调器的重启做好准备；如此，无线接口模块在接收到异常状态消息后，可向调制解调器发送重启请求，调制解调器在接收到重启请求后，可以基于该重启请求进行重启，使得资源标识恢复到预设数量，基于此，调制解调器可再次向网络设备发送附着请求，并在发送附着请求的过程中，能够伴随PDN连接的建立，以及调制解调器能够成功为此次PDN连接的建立分配一个资源标识，由此，终端设备可以尽快接入网络，便于终端设备可以尽快恢复正常的数据传输与通信。
实现方式二
实现方式二适用于终端设备接入第四代移动通信技术网络制式(4G)网络、第五代移动通信技术网络制式(5G)网络(例如，5G独立组网(standalone，SA))、无法激活数据业务或其他类型的建立数据链接场景。
可以理解的是，第四代移动通信技术网络制式(4G)网络(例如，LTE网络)附着到网络设备后，需要另外再建立新的PDN连接的情况下，也适用于实现方式二。
示例性地，调制解调器(modem)在无法获取待分配的资源标识时，可通知应用处理器(application processor，AP)中的无线接口模块，由无线接口模块触发调制解调器重启，使得资源标识的数量重新达到预设数量，便于调制解调器能够恢复向网络设备发送网络附着请求来接入网络；如图6所示。
其中，此处的无线接口模块为图3中的无线接口层。
需要说明的是，实现方式二中，调制解调器(modem)在无法获取待分配的资源标识时，通知应用处理器(application processor，AP)中的无线接口模块的方式可采用实现方式二中发送激活数据响应消息的方式，还可以采用实现方式一中发送异常状态消息的方式，采用实现方式一中发送异常状态消息的方式时，异常状态消息中可不包括失败原因值。
图6示出了本申请提供的一例数据业务恢复方法的流程示意图。如图6所示，该方法可以划分为两个不同的阶段，分别为2.1第一链接建立阶段和2.2第二链接建立阶段。
2.1第一链接建立阶段
其中，第一链接建立阶段可理解为由于调制解调器无法获取待分配的资源标识，调制解调器无法与网络设备建立数据链接的阶段；例如，如图6所示的S21-S23。

其中，激活数据请求用于指示开通或启用数据业务。
在一些实施例中，终端设备可以显示一个启动界面，启动界面中可以包括数据激活控件，该数据激活控件用于开通或启用数据业务。
例如，第一界面可以为图4所示的界面，数据激活控件可以为图4所示的界面中的控件1001；终端设备中的电话服务模块在接收到控件1001上的操作后，可响应于该操作，向无线接口模块发送激活数据请求。
应理解，上述以图4所示的界面为启动界面，数据激活控件为控件1001进行举例描述；本申请对启动界面的具体实现方式不做限定。本申请对数据激活控件的显示位置、显示样式、显示大小等参数不做限定。
S22、无线接口模块向调制解调器发送激活数据请求。
基于S21，无线接口模块可接收到电话服务模块发送的激活数据请求，从而，无线接口模块可继续将该激活数据请求下传，即向调制解调器发送激活数据请求，便于调制解调器基于该激活数据请求向网络设备发送数据链接请求，以使得终端设备接入网络。
S23、调制解调器无法获取待分配的资源标识。
其中，S23与图5所示实施例中的S11实现方式类似，此处不再赘述。

S24、调制解调器向无线接口模块发送激活数据响应消息。
其中，激活数据响应消息中包括有失败原因值，失败原因值用于表示调制解调器无法获取待分配的资源标识，无法向网络设备发送数据链接请求，无法建立分组数据网络连接，也无法接入网络。
S25、无线接口模块向电话服务模块发送激活数据响应消息。
基于S24，无线接口模块可接收到调制解调器发送的激活数据响应消息，从而，无线接口模块可继续将激活数据响应消息上传，即向电话服务模块发送激活数据响应消息，便于电话服务模块基于该激活数据响应消息向调制解调器发送重启请求，来重启调制解调器。
S26、电话服务模块向无线接口模块发送重启请求。
其中，重启请求用于请求调制解调器进行重启。

S30、调制解调器进行与网络设备之间的网络注册。
基于S29，调制解调器重启后，资源标识的数量重新达到预设数量，从而，调制解调器可进行与网络设备之间的网络注册。
在一些实施例中，网络注册过程可以包括：调制解调器向网络设备发送注册请求，网络设备在接受到注册请求后，可向调制解调器返回用于指示网络设备接受调制解调器注册到网络设备的响应消息，由此，调制解调器可基于第二网络制式的网络与网络设备之间完成网络注册。
在一些实施例中，第二网络制式的网络为第五代移动通信技术网络制式下的网络，即SA网络。
S31、调制解调器向网络设备发送数据链接建立请求。
基于S29，调制解调器重启后，资源标识的数量重新达到预设数量，调制解调器能够进行与网络设备之间的网络注册，在网络注册完成后，可以向网络设备发送数据链接建立请求，即可以重新建立协议数据单元(protocol data unit，PDU)会话。
其中，数据链接建立请求用于指示调制解调器请求启动数据传输业务。
在一些实施例中，网络设备在接收到数据链接建立请求后，可向调制解调器返回链接建立确认消息，来确认网络设备接受调制解调器与网络设备建立数据链接，由此，调制解调器可与网络设备建立数据链接，并向网络设备发送链接建立完成消息，从而终端设备可接入网络，便于终端设备进行正常的数据传输与通信。
可以理解的是，由于调制解调器重启后，资源标识的数量重新达到预设数量，那么，调制解调器向网络设备发送数据链接建立请求，从而建立PDU会话，从而，调制解调器能够分配一个资源标识，用来标识此次PDU会话的建立。
本申请中，在接收到电话服务模块通过无线接口模块发送的激活数据请求后，由于终端设备中的调制解调器无法获取待分配的资源标识，调制解调器可以确定调制解调器无法向网络设备发送数据链接请求，无法建立PDU会话，也无法接入网络；从而，终端设备中的调制解调器可向无线接口模块发送用于指示调制解调器无法获取待分配的资源标识的激活数据响应消息，为无线接口模块触发调制解调器的重启做好准备；如此，无线接口模块在接收到激活数据响应消息后，可向电话服务模块上传该激活数据响应消息，由此，电话服务模块在接收到该激活数据响应消息后，可通过无线接口模块向调制解调器发送重启请求，调制解调器在接收到重启请求后，可以基于该重启请求进行重启，使得资源标识恢复到预设数量，基于此，调制解调器可与网络设备之间再次进行网络注册，并再次向网络设备发送数据链接建立请求，来建立PDU会话，以及调制解调器能够成功为此次PDU会话的建立分配一个资源标识，由此，终端设备可以尽快接入网络，便于终端设备可以尽快恢复正常的数据传输与通信。

基于此，终端设备可采用图5所示的实施例，接入第四代移动通信技术网络制式(4G)网络。终端设备可采用图6所示的实施例，接入第五代移动通信技术网络制式(5G)网络。
终端设备可同时采用图5所示的实施例，以及图6所示的实施例，来避免终端设备中的调制解调器在接入4G网络，以及在接入5G网络时调制解调器无法获取待分配的资源标识，使得终端设备无法接入网络的情况。
考虑到终端设备可接入第四代移动通信技术网络制式(4G)网络，即LTE attach(附着)场景，调制解调器无法获取待分配的资源标识，调制解调器无法向网络设备发送附着请求，终端设备可选择图5所示的实施例。
考虑到终端设备可接入第四代移动通信技术网络制式(4G)网络(例如，需要再建立一个PDN连接，例如，更改网络接入技术(access point name，APN))或第五代移动通信技术网络制式(5G)网络(即非LTE attach场景，例如，5G独立组网(standalone，SA))，调制解调器无法获取待分配的资源标识，调制解调器无法向网络设备发送数据链接请求，终端设备可选择图6所示的实施例。
需要说明的是，图5所示的实施例，以及图6所示的实施例，不仅适用于调制解调器无法获取待分配的资源标识，使得终端设备无法接入网络的情况，还适用于其他调制解调器异常，使得终端设备无法正常接入网络的情况。在图5所示的实施例适用于其他调制解调器异常无法正常接入网络的情况时，异常状态消息可指示与其他调制解调器异常对应的信息，图6所示的实施例适用于其他调制解调器异常无法正常接入网络的情况时，激活数据响应消息可包括与其他调制解调器异常对应的信息。
