技术领域
本申请涉及通信领域，尤其涉及一种双卡双待双通方法、设备和存储介质。
背景技术
随着无线通信技术的不断发展，手机已成为当今社会人们日常工作、生活、娱乐等不可或缺的辅助工具。而随着运营商不同制式的推出，以及资费、上网、工作与私生活分离等多种因素的影响，越来越多的人拥有两张或更多的手机卡。为此，用户通常需要随身携带两部，甚至两部以上的手机，带来很大的不便。为了解决该问题，双卡双待的手机应运而生。
目前，双卡双待手机可以支持插两张客户识别模块(Subscriber Identity Module，SIM)卡或用户识别模块(User Identity Module，UIM)卡。但受制于硬件成本、设计空间等的限制，目前的手机通常仅支持双卡单待或双卡双待(Dual SIM dual standy，DSDS)，无法实现双卡双通(Dual SIM dual active，DSDA)的功能，从而导致用户在通过一张卡打电话时，另一张卡的通路则完全断掉，会漏接该卡的来电，影响用户使用。
发明内容
本申请实施例提供一种双卡双待双通方法、设备和存储介质，用于实现双卡双待双通，从而当通过一张通信卡打电话时，另一张卡的通路也不会被完全断掉，从而可以避免另一张卡的来电漏接的情况。
第一方面，本申请实施例提供一种双卡双待双通的方法，终端设备包括Q个射频通道，Q个射频通道中有N个发送射频通道，Q为大于1的整数，N为大于1且不大于Q的整数。其中，第一通信卡具有支持K1个发送射频通道的能力，第二通信卡具有支持K2个发送射频通道的能力，K1和K2均为正整数。终端设备向网络设备发送能力指示信息，终端设备接收网络设备发送的配置信息。当第一通信卡和第二通信卡插入终端设备时，能力指示信息用于指示：第一通信卡具有支持M个发送射频通道的能力，第二通信卡具有支持(N-M)个发送射频通道的能力；M为小于N且不大于K1的正整数，(N-M)为不大于K2的正整数。且：配置信息用于指示：将N个发送射频通道中的M个发送射频通道配置给第一通信卡，将N个发送射频通道中的除M个发送射频通道之外的(N-M)个发送射频通道配置给第二通信卡；当需要发送第一通信卡的上行数据，终端设备通过M个发送射频通道发送第一通信卡的上行数据；当需要发送第二通信卡的上行数据，终端设备通过(N-M)个发送射频通道发送第二通信卡的上行数据。如此，第一通信卡和第二通信卡都分配有用于 发送信号的射频通道，从而实现双卡双待双通的目的。
在一种可能地实施方式中，第一通信卡和第二通信卡插入终端设备，包括以下内容：第一通信卡插入终端设备，且未被禁用；第二通信卡插入终端设备，且未被禁用。也就是说，可以通过软件的方式禁用某张通信卡，若用户不想使用某张通信卡，则无需拔出该卡，仅通过软件方式禁用该卡即可。该方案可以提高方案的灵活性。
在一种可能地实施方式中，当第一通信卡和第二通信卡插入终端设备中，若第一通信卡为主卡，且K1小于N；能力指示信息用于指示：第一通信卡具有支持K1个发送射频通道的能力，第二通信卡具有支持(N-K1)个发送射频通道的能力。且：配置信息用于指示：将N个发送射频通道中的K1个发送射频通道配置给第一通信卡，将N个发送射频通道中的除K1个发送射频通道之外的(N-K1)个发送射频通道配置给第二通信卡。如此，可以在保证为第一通信卡和第二通信卡均分配有用于发送信号的射频通道的前提下，尽量维持主卡的硬件资源允许的最大上行能力，使主卡的性能可以发挥到最佳。
在一种可能地实施方式中，当第一通信卡插入终端设备中，第二通信卡未插入终端设备或第二通信卡插入终端设备但被禁用，则：当K1小于N时，能力指示信息用于指示：第一通信卡具有支持K1个用于发送信号的射频通道的能力；配置信息用于指示：将N个发送射频通道中的K1个发送射频通道配置给第一通信卡；当K1不小于N时，能力指示信息用于指示：第一通信卡具有支持K1个用于发送信号的射频通道的能力；配置信息用于指示：将N个发送射频通道中的N个发送射频通道配置给第一通信卡。若终端设备仅使用一张通信卡，则可以依据该通信卡的最大能力为其分配发送射频通道，从而可维持硬件资源允许的最大上行能力，使该通信卡的性能发挥到最佳。
在一种可能地实施方式中，当第二通信卡插入终端设备中，第一通信卡未插入终端设备或第一通信卡插入终端设备但被禁用，则：当K2小于N时，能力指示信息用于指示：第二通信卡具有支持K2个用于发送信号的射频通道的能力；配置信息用于指示：将N个发送射频通道中的K2个发送射频通道配置给第二通信卡；当K2不小于N时，能力指示信息用于指示：第二通信卡具有支持K2个用于发送信号的射频通道的能力；配置信息用于指示：将N个发送射频通道中的N个发送射频通道配置给第二通信卡。若终端设备仅使用一张通信卡，则可以依据该通信卡的最大能力为其分配发送射频通道，从而可维持硬件资源允许的最大上行能力，使该通信卡的性能发挥到最佳。

可以理解的是，本申请实施例示意的各模块间的接口连接关系，只是示意性说明，并不构成对终端设备的结构限定。在本申请另一些实施例中，终端设备也可以采用上述实施例中不同的接口连接方式，或多种接口连接方式的组合。
终端设备的无线通信功能可以通过天线1，天线2，移动通信模块150，无线通信模块160，调制解调处理器以及基带处理器等实现。
天线1和天线2用于发射和接收电磁波信号。终端设备中的每个天线可用于覆盖单个或多个通信频带。不同的天线还可以复用，以提高天线的利用率。例如：可以将天线1复用为无线局域网的分集天线。在另外一些实施例中，天线可以和调谐开关结合使用。
移动通信模块150可以提供应用在终端设备上的包括2G/3G/4G/5G等无线通信的解决方案。移动通信模块150可以包括至少一个滤波器，开关，功率放大器，低噪声放大器(low noise amplifier，LNA)等。移动通信模块150可以由天线1接收电磁波，并对接收的电磁波进行滤波，放大等处理，传送至调制解调处理器进行解调。移动通信模块150还可以对经调制解调处理器调制后的信号放大，经天线1转为电磁波辐射出去。在一些实施例中，移动通信模块150的至少部分功能模块可以被设置于处理器110中。在一些实施例中，移动通信模块150的至少部分功能模块可以与处理器110的至少部分模块被设置在同一个器件中。
调制解调处理器可以包括调制器和解调器。其中，调制器用于将待发送的低频基带信号调制成中高频信号。解调器用于将接收的电磁波信号解调为低频基带信号。随后解调器将解调得到的低频基带信号传送至基带处理器处理。低频基带信号经基带处理器处理后，被传递给应用处理器。应用处理器通过音频设备(不限于扬声器170A，受话器170B等)输出声音信号，或通过显示屏194显示图像或视频。在一些实施例中，调制解调处理器可以是独立的器件。在另一些实施例中，调制解调处理器可以独立于处理器110，与移动通信模块150或其他功能模块设置在同一个器件中。
无线通信模块160可以提供应用在终端设备上的包括无线局域网(wireless local area networks，WLAN)(如无线保真(wireless fidelity，Wi-Fi)网络)，蓝牙(bluetooth，BT)，全球 导航卫星系统(global navigation satellite system，GNSS)，调频(frequency modulation，FM)，近距离无线通信技术(near field communication，NFC)，红外技术(infrared，IR)等无线通信的解决方案。无线通信模块160可以是集成至少一个通信处理模块的一个或多个器件。无线通信模块160经由天线2接收电磁波，将电磁波信号调频以及滤波处理，将处理后的信号发送到处理器110。无线通信模块160还可以从处理器110接收待发送的信号，对其进行调频，放大，经天线2转为电磁波辐射出去。
在一些实施例中，终端设备的天线1和移动通信模块150耦合，天线2和无线通信模块160耦合，使得终端设备可以通过无线通信技术与网络以及其他设备通信。该无线通信技术可以包括全球移动通讯系统(global system for mobile communications，GSM)，通用分组无线服务(general packet radio service，GPRS)，码分多址接入(code division multiple access，CDMA)，宽带码分多址(wideband code division multiple access，WCDMA)，时分码分多址(time-division code division multiple access，TD-SCDMA)，长期演进(long term evolution，LTE)，BT，GNSS，WLAN，NFC，FM，和/或IR技术等。该GNSS可以包括全球卫星定位系统(global positioning system，GPS)，全球导航卫星系统(global navigation satellite system，GLONASS)，北斗卫星导航系统(beidou navigation satellite system，BDS)，准天顶卫星系统(quasi-zenith satellite system，QZSS)和/或星基增强系统(satellite based augmentation systems，SBAS)。
内部存储器121可以用于存储计算机可执行程序代码，该可执行程序代码包括指令。内部存储器121可以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。存储数据区可存储终端设备使用过程中所创建的数据(比如音频数据，电话本等)等。此外，内部存储器121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，通用闪存存储器(universal flash storage，UFS)等。处理器110通过运行存储在内部存储器121的指令，和/或存储在设置于处理器中的存储器的指令，执行终端设备的各种功能应用以及数据处理。
SIM卡接口195用于连接SIM卡。SIM卡可以通过插入SIM卡接口195，或从SIM卡接口195拔出，实现和终端设备的接触和分离。终端设备可以支持L个SIM卡接口，N为大于1的正整数。SIM卡接口195可以支持Nano SIM卡，Micro SIM卡，SIM卡、UIM卡等。同一个SIM卡接口195可以同时插入多张卡。该多张卡的类型可以相同，也可以不同。SIM卡接口195也可以兼容不同类型的SIM卡。SIM卡接口195也可以兼容外部存储卡。终端设备通过SIM卡和网络交互，实现通话以及数据通信等功能。在一些实施例中，终端设备采用eSIM，即：嵌入式SIM卡。eSIM卡可以嵌在终端设备中，不能和终端设备分离。
图3示例性示出了本申请实施例适用的一种终端设备的结构示意图，如图3所示，终端设备包括4个射频通道，分别为射频通道1、射频通道2、射频通道3和射频通道4。
其中，射频通道1和射频通道2既支持信号的接收，也支持信号的发送。射频通道3和射频通道4仅支持信号的接收。本申请实施例中将能够支持信号的发送的射频通道也称为发送射频通道，比如可以将射频通道1和射频通道2称为发送射频通道。进行信号的发送时所用到的元器件的数量比进行信号接收时所用到的元器件的数量多，在一种可能地实施方式中，考虑到终端设备的成本，因此支持信号发送的射频通道的数量会大于支持信号 接收的射频通道的数量。
本申请实施例中射频通道是指能够实现信号收发的一系列的硬件结构和/或软件。本申请实施例中以4个射频通道为例进行示意。本申请实施例中可以将用于实现信号收发的硬件结构和/或软件称为射频资源。比如一个射频通道上用于接收信号的硬件结构和/或软件可以称为用于接收信号的射频资源。将一个射频通道上用于发送信号的硬件结构和/或软件称为用于发送信号的射频资源。再比如一个射频通道仅仅支持接收信号，也可以将该射频通道上的硬件和/或软件分为几部分射频资源，可以将该射频通道的一部分射频资源分配给第一通信卡使用，以实现对第一通信卡信号的接收；将另一部分射频资源分配给第二通信卡使用，以实现对第二通信卡信号的接收。
比如图3中，射频通道1中的硬件结构和/或软件分为三个部分的射频资源，分别为用于发送信号的射频资源305、用于接收信号的射频资源306和用于接收信号的射频资源307。网络设备将一个射频资源分配给一个通信卡后，该通信卡可以通过该射频资源进行信号的收发。
如图3所示，终端设备中可以包括多个通信卡接口，比如图3中所示的第一通信卡接口341和第二通信卡接口342。通信卡接口可以是上述图2中的SIM卡接口195。在具体使用时可以将通信卡插入通信卡接口中，以实现通信卡与终端设备的连接。当将通信卡拔出通信卡接口时则通信卡与终端设备之间断开连接。
每个通信卡的运营商都规定了该通信卡所采用的频率。本申请实施例中第一通信卡和第二通信卡采用的频率可以相同，也可以不同，本申请实施例不做限定。具体实施中，若第一通信卡和第二通信卡的频率相同，则会带来同频干扰，为了避免这种问题，用户可以选用采用频率不同的两张通信卡。以第一通信卡使用频率A进行数据传输，第二通信卡使用频率B进行数据传输为例进行说明，频率A和频率B为两个不同的频率。如图3所示，终端设备中可以通过双工器303或开关304实现同一个频段的信号的接收和发送。举个例子，将射频通道1中的用于发送信号的射频资源305和用于接收信号的射频资源306分配给第一通信卡使用，将用于接收信号的射频资源307分配给第二通信卡使用，以射频通道1连接开关304为例进行介绍，若开关实现了用于发送信号的射频资源305与滤波器302的连接，则可以通过用于发送信号的射频资源305实现信号的发送，此时无法通过接收信号的射频资源305实现信号的接收。若开关实现了用于接收信号的射频资源306与滤波器302的连接，则接收信号的射频通路处于通路状态，可以通过接收信号的射频资源305实现信号的接收，但此时无法以通过用于发送信号的射频资源305实现信号的发送。如此，可以看出，终端设备中可以通过双工器303或开关304实现同一个频段的信号的接收和发送。
如图3所示，由于不同的通信卡使用不同的频率，因此在同一个射频通道中，可以通过滤波器将属于两个频率的两个信号分开。举个例子，将射频通道1中的用于发送信号的射频资源305和用于接收信号的射频资源306分配给第一通信卡使用，将用于接收信号的射频资源307分配给第二通信卡使用，第一通信卡可以使用频率A进行数据传输，第二通信卡可以使用频率B进行数据传输，如图3所示，可以通过滤波器302将频率A的信号和频率B的信号分离开来。
如图3所示，一个射频通道可以连接一个天线，从而通过天线实现该射频通道上的信号的传输，比如射频通道1的信号可以通过天线301进行传输。天线301属于图2中的天 线1的类型的天线。
类似地，如图3所示，射频通道2中包括有用于发送信号的射频资源315、用于接收信号的射频资源316、用于接收信号的射频资源317、双工器313、开关314、滤波器312以及天线321。作用与射频通道1中类似，在此不再赘述。射频通道3与射频通道1相比，仅包括用于接收信号的射频资源(如用于接收信号的射频资源326和用于接收信号的射频资源327)，因此射频通道3中可以仅设置滤波器322和天线321，以实现将不同频段的信号的接收目的。类似地，射频通道4中也仅设置有用于接收信号的射频资源336、用于接收信号的射频资源337、滤波器332和天线331，不再详述。
本申请实施例中的后续内容中，以终端设备有两张通信卡为例进行示例，分别为第一通信卡和第二通信卡。本申请实施例中需要注意，“通信卡”是上位概念，是泛称，具体是指第一通信卡和第二通信卡。
本申请实施例中，针对第一通信卡和第二通信卡中的一个通信卡：该终端设备确定该通信卡插入卡槽中，则确定该通信卡处于使用状态。或者，该终端设备确定该通信卡未插入卡槽中，则确定该通信卡处于未使用状态。再比如，针对第一通信卡和第二通信卡中的一个通信卡，该终端设备确定该通信卡插入卡槽中，且该通信卡未被禁用(比如可以通过软件方式来禁用某一张通信卡)，则确定该通信卡处于使用状态。或者，该终端设备确定该通信卡插入卡槽中，且该通信卡被禁用，则确定该通信卡处于未使用状态。也就是说，可以根据通信卡是否插入卡槽，以及通信卡插入卡槽但是否被禁用(比如通过软件禁用)等来判断通信卡是处于使用状态，还是处于未使用状态。
一种可选地实施方式中，本申请实施例中后续提到的第一通信卡处于使用状态是指第一通信卡插入终端设备中，第一通信卡处于未使用状态是指第一通信卡未插入终端设备中；第二通信卡处于使用状态是指第二通信卡插入终端设备中，第二通信卡处于未使用状态是指第二通信卡未插入终端设备中。
另一种可选地实施方式中，第一通信卡处于使用状态是指第一通信卡插入终端设备中，且未被禁用。第一通信卡处于未使用状态是指第一通信卡插入终端设备中，但被禁用，或者是第一通信卡未插入终端设备中。第二通信卡处于使用状态是指第二通信卡插入终端设备中，且未被禁用。第二通信卡处于未使用状态是指第二通信卡插入终端设备中，但被禁用，或者是第二通信卡未插入终端设备中。
基于上述内容，本文中首选对一种现有技术进行阐述，以第一通信卡为主卡，且主卡具有支持两个发送射频通道的能力，第二通信卡为副卡，副卡具有支持两个发送射频通道的能力，且终端设备一共具有两个发送射频通道为例进行说明。
首选，终端设备会上报真实的主卡和副卡的能力。也就是说，现有技术中，终端设备上报的通信卡支持的发送射频通道的数量为真实值。具体上报内容为：主卡具有支持两个发送射频通道的能力，副卡具有支持两个发送射频通道的能力。网络设备收到该信息之后，会依据终端设备上报的主卡和副卡的能力，以及终端设备具有的发送射频通道的数量，来为主卡和副卡分配用意发送信号的射频通道。首选要满足主卡的能力，因此网络设备会为主卡分配两个发送射频通道，因为终端设备一共就只有两个发送射频通道，因此网络设备不再为副卡分配发送射频通道，而在实际通信过程中，副卡在需要使用发送射频通道时，需要通过抢占方式去使用该发送射频通道。
上述方案中，当一个通信卡处于使用状态时，另一个通信卡容易出现漏接电话的情况。 举个例子详细说明一下：比如主卡正处于打电话状态，主卡占用两个发送射频通道来发送数据，这时，副卡有一个来电，但是由于两个发送射频通道都被主卡占用着，因此副卡没有办法使用该发送射频通道来发送数据，因此副卡和网络的链路就无法建立，从而副卡也就无法成功接入该来电。可以看出，这种方案中无法实现双卡双通的目的。为了解决该问题，本申请提供一种双卡双待双通的方案，图4示例性示出了一种双卡双待双通方法流程示意图，如图4所示，包括：
步骤501，终端设备向网络设备发送能力指示信息。
一般来讲，终端设备想要获取服务，需要向网络注册，这个注册过程被称为Attach(以LTE系统为例)，终端设备在上Attach过程中可以向网络发送会话接入请求，以请求接入网络。网络向终端设备发送第一信令，其中，第一信令用于指示终端设备上报能力指示信息。终端设备在接收到第一信令之后，可以发送能力指示信息。根据协议规定，例如标识当前终端设备的每个通信卡的能力可以通过以下三个字段(该三个字段是协议38.306规定的)来指示：
第一个字段：“Supported maximum number of SRS antenna port per each SRS resource”，该字段是指supportedSRS-Resources中所支持的最大端口数的相关信息。
第二个字段：“maxNumberMIMO-LayersCB-PUSCH”，该字段是指采用上行Codebook模式时，上行支持的最大流数。
第三个字段：“maxNumberMIMO-LayersNonCB-PUSCH”，该字段是指采用上行NonCodebook模式时，上行支持的最大流数。
以第一通信卡为例，若上报的能力指示信息中指示“第一通信卡支持1个发送射频通道”，则能力指示信息中：第一通信卡对应的上述第一个字段的内容为1。针对上述第二个字段和第三个字段则需要根据终端设备的实际情况进行确定，比如第一通信卡可以支持Codebook模式下1个上行发送通道，上行NonCodebook模式1个上行发送通道。第二通信卡对应的三个字段的内容与第一通信卡对应的三个字段的内容类似，不再赘述。再比如，若上报的能力指示信息中指示第一通信卡支持2个发送射频通道，则能力指示信息中：第一通信卡对应的上述第一个字段的内容为2。针对上述第二个字段和第三个字段则需要根据终端设备的实际情况进行确定，比如第一通信卡可以支持Codebook模式下2个上行发送通道，上行NonCodebook模式1个上行发送通道。
步骤502，终端设备接收网络设备发送的配置信息。
其中，终端设备包括Q个射频通道，Q个射频通道中有N个发送射频通道，Q为大于1的整数，N为大于1且不大于Q的整数。
在步骤501中，终端设备上报的能力指示信息中包括有第一通信卡支持的发送射频通道的数量，以及第二通信卡支持的发送射频通道的数量。
本申请实施例步骤501中，终端设备上报的通信卡支持的发送射频通道的数量是要结合当前处于使用状态的通信卡的数量，以及终端设备具有的发送射频通道的总数量来确定的，并不是如现有技术中仅仅是上报通信卡真实的所支持的发送射频通道的数量。
比如，第一种可能地应用场景中，当第一通信卡和第二通信卡处于使用状态，第一通信卡具有支持K1个发送射频通道的能力，第二通信卡具有支持K2个发送射频通道的能力，K1和K2均为正整数。
在第一种可能地应用场景中，首选由于终端设备仅仅具有N个发送射频通道，能力有 限，若(K1+K2)大于N，也就是说N个发送射频通道并不能同时满足主卡和副卡的最大发送能力。则，本申请实施例中终端设备在上报能力指示信息的时候，并不上报各个通信卡实际支持的发送射频通道的数量，而是通过能力指示信息指示：第一通信卡具有支持M个发送射频通道的能力，第二通信卡具有支持(N-M)个发送射频通道的能力；M为小于N且不大于K1的正整数，(N-M)为不大于K2的正整数。
基于上述第一种可能地应用场景中的能力指示信息，网络设备为各个通信卡配置发送射频通道。在该应用场景中，配置信息用于指示：将N个发送射频通道中的M个发送射频通道配置给第一通信卡，将N个发送射频通道中的除M个发送射频通道之外的(N-M)个发送射频通道配置给第二通信卡。
在一种可选地实施方式中，将N个发送射频通道中的一个发送射频通道配置给第一通信卡具体是指：将一个具有发送信号能力的射频通道上的用于发送信号的射频资源分配给第一通信卡使用，以实现第一通信卡信号的发送。在一种可选地实施方式中，将N个发送射频通道中的一个发送射频通道配置给第二通信卡具体是指：将一个具有发送信号能力的射频通道上的用于发送信号的射频资源分配给第二通信卡使用，以实现第二通信卡信号的发送。
步骤503，当需要发送第一通信卡的上行数据，终端设备通过M个发送射频通道发送第一通信卡的上行数据。
步骤504，当需要发送第二通信卡的上行数据，终端设备通过(N-M)个发送射频通道发送第二通信卡的上行数据。
可以看出，虽然第一通信卡实际上支持K1个发送射频通道，第二通信卡实际支持K2个发送射频通道，但是本申请实施例中终端设备上报的能力指示信息中不再是简单的上报这一真实值，而是：结合终端设备实际拥有的发送射频通道的能力的数量，以及当前处于使用状态的通信卡的数量，去上报每个通信卡所支持的发送射频通道的数量。例如，上述内容中上报第一通信卡具有支持M个发送射频通道的能力，第二通信卡具有支持(N-M)个发送射频通道的能力。M可能实际上是比K1小，(N-M)可能实际上也是比K2小的。可以看出，本申请实施例中对终端设备上报的能力指示信息进行了改进，与现有技术中去上报各个通信卡的真实的支持的发送射频通道的数量的方案是不同的。
进一步，由于终端设备上报的能力指示信息中，第一通信卡支持M个发送射频通道，第二通信卡支持(N-M)个发送射频通道，因此网络设备将N个发送射频通道中的M个发送射频通道配置给第一通信卡，将N个发送射频通道中的除M个发送射频通道之外的(N-M)个发送射频通道配置给第二通信卡。由于两个通信卡都分配了发送射频通道，因此即使第一通信卡处于通话状态，占用了M个为其分配的发送射频通道，这时，若有第二通信卡存在来电，则第二通信卡可以通过为其分配的(N-M)个发送射频通道来与网络建立链路，从而接收该来电，从而可以避免一张通信卡处于使用状态下另一张通信卡漏接电话的问题，如此，可以实现双卡双通的目的。
在上述第一种可能地应用场景中，一种可能地实施方式中，终端设备上报的能力指示信息中，若N为偶数，则可以将N个发送射频通道平均分成两份，每个通信卡各占一份，这种情况下，M为N/2，(N-M)为N/2。举个例子，N为2，则上报的能力指示信息中，第一通信卡支持的发送射频通道的数量为1，第二通信卡支持的发送射频通道的数量为1。网络设备下发的配置信息中指示将2个发送射频通道中的一个分给第一通信卡，将另一个 发送射频通道分配给第二通信卡。如此，第一通信卡和第二通信卡可以实现双卡双通的目的。
图5示例性示出了第一种应用场景下射频通道的分配示意图，如图5所示，若第一通信卡具有支持2个发送射频通道的能力，该第二通信卡具有支持2个发送射频通道的能力。此处以K1和K2均为2仅仅是一个示例，具体K1和K2的值可以根据通信卡的具体能力的不同而不同。若当前第一通信卡和第二通信卡均处于使用状态，则终端设备上报的能力指示信息中：该第一通信卡具有支持1个发送射频通道的能力，且该第二通信卡具有支持1个发送射频通道的能力，由于在图5中终端设备具有2个发送射频通道，因此可以给第一通信卡和第二通信卡分别分配1个发送射频通道。如图5所示，具体来说，可以将射频通道1用于发送信号的射频资源分配给第一通信卡使用，射频通道2的用于发送信号的射频资源分配给第二通信卡使用。通过图5可以看出，在终端设备使用双卡的情况下，可以为双卡中的每个通信卡都分配部分用于发送信号的射频资源，从而可以实现双卡双待双通的目的。
如图5所示，4个射频通道中每个射频通道的用于接收信号的射频资源均共享给第一通信卡和第二通信卡使用。比如，针对射频通道1中，将射频通道1中用于发送信号的射频资源305分配给第一通信卡使用，将射频通道1中用于发送接收信号的射频资源306分配给第一通信卡使用，可以通过双工器303或者开关304实现对第一通信卡的信号的收发功能。本申请实施例中用于发送信号的射频资源可以实现信号的发送，用于接收信号的射频资源可以实现信号的接收。将射频通道1中用于接收信号的射频资源307分配给第二通信卡使用。再比如，针对射频通道2中，将射频通道2中用于发送信号的射频资源315分配给第二通信卡使用，将射频通道2中用于发送接收信号的射频资源316分配给第二通信卡使用，可以通过双工器313或者开关314实现对第二通信卡的信号的收发功能。将射频通道2中用于接收信号的射频资源317分配给第一通信卡使用。再比如，针对射频通道3中，将射频通道3中用于发送接收信号的射频资源326分配给第一通信卡使用，将射频通道3中用于接收信号的射频资源327分配给第二通信卡使用。再比如，针对射频通道4中，将射频通道4用于发送接收信号的射频资源336分配给第一通信卡使用，将射频通道4中用于接收信号的射频资源337分配给第二通信卡使用。
在图5所示的例子中，当然如果终端设备具有大于两个2发送射频通道，比如4个发送射频通道，若第一通信卡具有支持2个发送射频通道的能力，该第二通信卡具有支持2个发送射频通道的能力，那么，上报的能力指示信息中可以指示第一通信卡具有支持2个发送射频通道的能力，第二通信卡具有支持2个发送射频通道的能力，如此，则网络设备为第一通信卡和第二通信卡分别配置2个发送射频通道。
上述内容论述了第一种可能地应用场景下的相关方案。具体实施中可能还存在第二种可能地应用场景：第一通信卡处于使用状态，且该第二通信卡处于未使用状态。
在第二种可能地应用场景中，即当该第一通信卡处于使用状态，且该第二通信卡处于未使用状态，则：当该K1小于该N时，该能力指示信息用于指示：该第一通信卡具有支持K1个发送射频通道的能力。当该K1不小于该N时，该能力指示信息用于指示：该第一通信卡具有支持N个发送射频通道的能力。该实施方式中，相对应的，网络设备接收终端设备发送的能力指示信息，根据能力指示信息为第一通信卡分配发送射频通道。网络设备根据能力指示信息为第一通信卡配置N个发送射频通道。图6示例性示出了第一通信卡 处于使用状态时，在图3的基础上示出了一种双卡情况下射频通道的分配示意图，如图6所示，若第一通信卡具有支持2个发送射频通道的能力，该第二通信卡具有支持2个发送射频通道的能力。若当前第一通信卡处于使用状态，则终端设备上报的能力指示信息中：该第一通信卡具有支持2个发送射频通道的能力，即由于在图6中，N为2，因此将M取2。如图6所示，可以将2个发送射频通道均分配给第一通信卡使用，具体来说，可以射频通道1用于发送信号的射频资源分配给第一通信卡使用，射频通道2的用于发送信号的射频资源也分配给第一通信卡使用。而射频通道3和射频通道4中的一部分用于接收信号的射频资源则分配给第一通信卡使用。通过图6的示例可以看出，若终端设备仅使用一张通信卡，则可以依据该通信卡的最大能力为其分配用于发送信号的射频资源，从而可维持硬件资源允许的最大上行能力，使该通信卡的性能发挥到最佳。
具体实施中可能还存在第三种可能地应用场景：第一通信卡处于未使用状态，第二通信卡处于使用状态。
在第三种可能地应用场景中，即第一通信卡处于未使用状态，第二通信卡处于使用状态，则：当该K2小于该N时，该能力指示信息用于指示：该第二通信卡具有支持K2个发送射频通道的能力；当该K2不小于该N时，该能力指示信息用于指示：该第二通信卡具有支持N个发送射频通道的能力。该实施方式中，相对应的，网络设备接收终端设备发送的能力指示信息，根据能力指示信息为第二通信卡分配发送射频通道。网络设备根据能力指示信息为第二通信卡配置N个发送射频通道。图7示例性示出了第二通信卡处于使用状态时，在图3的基础上示出了一种双卡情况下射频通道的分配示意图，如图7所示，若第二通信卡具有支持2个发送射频通道的能力，第二通信卡具有支持2个发送射频通道的能力。若当前第二通信卡处于使用状态，则终端设备上报的能力指示信息中：该第二通信卡具有支持2个发送射频通道的能力，可以将2个发送射频通道均分配给第二通信卡使用，具体来说，可以如图7所示，射频通道1用于发送信号的射频资源分配给第二通信卡使用，射频通道2的用于发送信号的射频资源分配给第二通信卡使用。而射频通道3和射频通道4中的一部分用于接收信号的射频资源则分配给第二通信卡使用。当然，在图7的示例中，若K2为1，则终端设备上报的能力指示信息中：该第二通信卡具有支持1个发送射频通道的能力，可以将1个发送射频通道分配给第二通信卡使用，具体来说，可以将射频通道2上用于发送信号的射频资源315分配给第二通信卡使用。通过图7的示例可以看出，若终端设备仅使用一张通信卡，则可以依据该通信卡的最大能力为其分配用于发送信号的射频资源，从而可维持硬件资源允许的最大上行能力，使该通信卡的性能发挥到最佳。
在上述步骤501中，本申请实施例中能力指示信息中指示的通信卡支持的发送射频通道的数量与通信卡实际支持的发送射频通道的数量可能相同，也可能不同。本申请实施例中还提供一种现有技术的方案，用于与上述步骤501和步骤502提供的方案进行对比，现有技术的方案中，能力指示信息中指示的通信卡支持的发送射频通道的数量与通信卡实际支持的发送射频通道的数量相同。下面通过表1对本申请实施例和对比方案进行对比示例。
表1本申请实施例与对比方案的对比示例
Figure PCTCN2020124462-appb-000001
Figure PCTCN2020124462-appb-000002
表1中，以终端设备包括2个发送射频通道为例进行示意，即N为2。表1中的1T表示1个射频通道，2T表示2个射频通道。表1中的通信卡实际支持的发送射频通道的数量是指通信卡硬件资源能支持的最大数量的发送射频通道的数量。主卡和副卡为终端设备预设的，比如插入第一个预设卡槽中的通信卡为主卡，插入第二预设卡槽中的通信卡为副卡。或者通过软件来指定通信卡的身份为主卡还是副卡。表1中以主卡和副卡都处于使用状态为例介绍本申请实施例的方案。
以表1“2.6GHz以上第一种情况”为例进行说明，其它应用场景与之类似，不再一一赘述。以第一通信卡为主卡，第二通信卡为副卡为例进行说明。第一通信卡支持2T，第二通信卡支持1T，这种情况下，第一通信卡和第二通信卡都处于使用状态下，采用本申请实施例提供的方案，则上报的能力指示信息中指示第一通信卡支持1个发送射频通道的数量，第二通信卡支持1个发送射频通道的数量，网络设备为将一个发送射频通道分配给第一通信卡，将另一个发送射频通道分配给第二通信卡，如此可以实现双卡双通的目的。进一步，看对比方案中，终端设备上报的能力指示信息中指示主卡支持2个发送射频通道的数量，副卡支持1个发送射频通道的数量，网络设备将两个发送射频通道全部分配给主卡使用，当副卡需要使用时，可以通过现有技术去抢占发送信号的射频通道，以发送信号，这种情况下未能实现双卡双通的目的。
上述步骤501中，又一种可选地实施方式中，若该第一通信卡为主卡，且该K1小于该N，则该M为该K1；若该第二通信卡为主卡，且该K2小于该N，则该(N-M)为该K2。该示例中，若终端设备的发送射频通道数量较多，可以在支持主卡的最大上行发送能力的情况下，还有剩余的发送射频通道，则可以维持主卡的最大上行发送能力，并且将剩余的发送射频通道分配给副卡使用，从而既维持了主卡的硬件资源允许的最大上行能力，也保证了双卡双通的目的。
本申请实施例中，终端设备有双卡模式和单卡模式，其中，双卡模式是指是第一通信卡合第二通信卡都处于使用状态，单卡模式是指第一通信卡和第二通信卡中仅有一张处于使用状态。当终端设备在双卡模式和单卡模式之间进行转换时，上述步骤502中的能力指示信息会被上报。下面具体来说，终端设备的能力指示信息可以是终端设备在重新接入网络时发起的，当然，比如终端设备开机时会重新接入网络，这种情况下会上报能力指示信息。再比如，当终端设备的通信卡的使用模式发生变更，终端设备也会重新接入网络，这种情况下，也会重新上报能力指示信息。
举个例子，终端设备当前第一通信卡和第二通信卡都处于使用状态，终端设备将从双卡模式切换为单卡模式，比如终端设备将采取仅使用第一通信卡的模式，则用户即将采取的操作为：第二通信卡可能被用户从卡槽中取出，或者通过软件的方式禁用第二通信卡。该情况下，终端设备均需要重新接入网络，当然也需要重新上报能力指示信息。再举个例子，终端设备从单卡模式切换至双卡模式，比如当前是仅使用第一通信卡，则切换后，终端设备的第一通信卡和第二通信卡都处于使用状态，这种情况下，用户要采取的操作是：将第二通信卡插入卡槽，或者通过软件的方式解除对第二通信卡的禁用，该情况下，终端设备也均需要重新接入网络，当然也需要重新上报能力指示信息。
本申请实施例中“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a,b,或c中的至少一项(个)，可以表示：a,b,c,a-b,a-c,b-c,或a-b-c，其中a,b,c可以是单个，也可以是多个。
以及，除非有特别说明，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。例如，第一通信卡和第二通信卡，只是为了区分不同的通信卡，而并不是表示这两个通信卡的优先级或者重要程度等的不同。
