为便于理解本申请实施例的技术方案，以下对本申请实施例相关的技术方案进行说明。
随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性、复杂性，为此第三代合作伙伴计划(3 rd Generation Partnership Project，3GPP)国际标准组织开始研发5G。5G的主要应用场景为：增强移动超宽带(enhanced Mobile Broadband，eMBB)、低时延高可靠通信(Ultra-Reliable Low-Latency Communications，URLLC)、大规模机器类通信(massive Machine-Type Communications，mMTC)。
一方面，eMBB仍然以用户获得多媒体内容、服务和数据为目标，其需求增长十分迅速。另一方面，由于eMBB可能部署在不同的场景中，例如室内，市区，农村等，其能力和需求的差别也比较大，所以不能一概而论，必须结合具体的部署场景详细分析。URLLC的典型应用包括：工业自动化，电力自动化，远程医疗操作(手术)，交通安全保障等。mMTC的典型特点包括：高连接密度，小数据量，时延不敏感业务，模块的低成本和长使用寿命等。

RRC状态
5G为了降低空口信令和快速恢复无线连接，快速恢复数据业务的目的，定义了一个新的无线资源控制(Radio Resource Control，RRC)状态，即RRC非激活(RRC_INACTIVE)状态。这种状态有别于RRC空闲(RRC_IDLE)状态和RRC激活(RRC_ACTIVE)状态。其中，
1)RRC_IDLE状态(简称为空闲(idle)态)：移动性为基于终端设备的小区选择重选，寻呼由核心网(Core Network，CN)发起，寻呼区域由CN配置。基站侧不存在终端设备上下文，不存在RRC连接。
2)RRC_CONNECTED状态(简称为连接(connected)态)：存在RRC连接，基站侧和终端设备侧存在终端设备上下文。网络侧知道终端设备的位置是具体小区级别的。移动性是网络侧控制的移动性。终端设备和基站之间可以传输单播数据。
3)RRC_INACTIVE状态(简称为非激活(inactive)态)：移动性为基于终端设备的小区选择重选，存在接入网和核心网之间的连接，终端设备的上下文存在某个基站上，寻呼由无线接入网(Radio Access Network，RAN)触发，基于RAN的寻呼区域由RAN管理，网络侧知道终端设备的位置是基于RAN的寻呼区域级别的。当终端设备在RAN配置的无线接入网通知区域(Radio Access Network Notification Area，RNA)内移动时不需要通知网络侧，但当移动出RNA时需要通知网络侧。

双卡双待/双网双待
双卡双待手机，是指一部手机可以同时装下两张通信卡，并且这两张通信卡均处于待机状态。双卡双待一般指同一种网络制式的双卡双待，例如GSM网络的双卡双待，CDMA网络的双卡双待，PHS网络的双卡双待。
双网双待是指一部手机可同时插入两张不同网络的通信卡，并使之同时处于开机状态，用户无需切换网络，即可任意拨打、接听和收发短信。
目前，手机一般不支持纯粹的双发双收(简称为双通)，双发双收是指手机同时通过两个通信卡在两个网络上进行数据的上行发送和下行接收。一般来说，大多数手机都只支持单发单收或单发双收，这也就意味着手机在某一时刻只能执行一张通信卡上的业务。然而，实现双通是未来手机发展的一个趋势。在5G中，对于支持双卡双待或者双网双待的手机的两张通信卡，其中一张通信卡可以驻留在LTE小区，另一张通信卡可以驻留在NR小区；或者，两张通信卡都驻留在NR小区。另一方面，两个通信卡可以是同一个运营商的通信卡，也可以是不同运营商的通信卡。
目前，双卡手机中的一个通信卡如果正在进行业务，而另一个通信卡也需要进行业务，例如另一个通信卡接收到了寻呼需要接收业务，或者另一个通信卡初始了业务，会存在两个通信卡的业务发生冲突的问题，如何处理另一个通信卡的业务以及如何协调两个通信卡的业务需要解决。为此，提出了本申请实施例的以下技术方案。
需要说明的是，本申请实施例中的“终端设备”可以是手机、平板电脑、穿戴式设备等，终端设备具有至少两张通信卡，例如终端设备具有2张通信卡或3张通信卡等。以下实施例以两张通信卡为例进行说明，不局限于此，两张以上通信卡的方案同样适用于本申请实施例的技术方案。
需要说明的是，本申请实施例对第一通信卡和第二通信卡的类型不做限制。例如第一通信卡和第二通信卡都是用户识别模块(Subscriber Identity Module，SIM)卡。例如第一通信卡和第二通信卡都是全球用户识别模块(Universal Subscriber Identity Module，USIM)卡。例如第一通信卡是SIM卡，第二通信卡是USIM卡。例如第一通信卡是USIM卡，第二通信卡是SIM卡。
另一方面，本申请实施例对第一通信卡和第二通信卡支持的网络类型不做限制，例如第一通信卡支持LTE网络(即第一通信卡对应的第一基站为LTE基站)，第二通信卡支持NR网络(即第二通信卡对应的第二基站为NR基站)。例如第一通信卡和第二通信卡都支持NR网络(即第一通信卡和第二通信卡和第二通信卡对应的第二基站均为NR基站)。
再一方面，本申请实施例对第一通信卡和第二通信卡所属的运营商不做限制，例如第一通信卡和第二通信卡可以属于同一个运营商，也可以属于不同的运营商。
图2是本申请实施例提供的通信方法的流程示意图一，如图2所示，所述通信方法包括以下步骤：
步骤201：终端设备向第一基站发送RRC恢复请求消息，第一基站接收终端设备发送的RRC恢复请求消息，所述第一基站为所述终端设备中的第一通信卡对应的基站，所述RRC恢复请求消息用于指示所述终端设备不响应寻呼或者指示所述终端设备的繁忙指示。
本申请实施例中，终端设备具有第一通信卡和第二通信卡，其中，第一通信卡处于非激活态，第二通信卡处于连接态或者非激活态或者空闲态。在一可选方式中，第一通信卡处于非激活态，第二通信卡处于连接态。
参照图3，终端设备具有第一通信卡和第二通信卡，其中，第一通信卡对应的网络为第一网络，第二通信卡对应的网络为第二网络。一方面，终端设备可以通过第一通信卡接入第一网络，实现在第一网络上进行业务。另一方面，终端设备可以通过第二通信卡接入第二网络，实现在第二网络上进行业务。这里，第一网络和第二网络的类型可以相同，也可以不同。例如第一网络为LTE网络，第二网络为NR网络。再例如第一网络和第二网络都是NR网络。
本申请实施例中，终端设备的第一通信卡处于非激活态。终端设备的第二通信卡处于连接态。举个例子：终端设备中存在两个USIM卡，分别为USIM-A卡和USIM-B卡。其中，USIM-A卡存在进行的业务，处于连接态；USIM-B卡处于非激活态，接收到寻呼消息。
需要说明的是，第一网络是指第一基站对应的网络，第二网络是指第二基站对应的网络。终端设备与第一基站之间的通信是通过第一通信卡实现的，终端设备与第二基站之间的通信是通过第二通信卡实现的。举个例子：终端设备中存在两个USIM卡，分别为USIM-A卡和USIM-B卡。其中，终端设备可以通过USIM-A卡与第一基站实现通信，终端设备可以通过USIM-B卡与第二基站实现通信。
本申请实施例中，所述第一基站接收终端设备发送的RRC恢复请求消息之前(即所述终端设备向第一基站发送RRC恢复请求消息之前)，所述方法还包括：
所述第一基站向所述终端设备发送寻呼消息，所述终端设备接收所述第一基站发送的寻呼消息，所述寻呼消息携带寻呼原因；所述寻呼原因用于所述终端设备的非接入(NAS)层或者接入(AS)层确定是否响应所述寻呼消息。
这里，可选地，所述寻呼消息由锚基站触发，所述寻呼消息中的寻呼原因由核心网控制面网元通知给所述锚基站。例如：终端设备的下行数据达到锚基站时，锚基站触发针对该终端设备的寻呼，通知RNA范围内的基站(如第一基站)向终端设备发送寻呼消息。这里，所述寻呼消息中的寻呼原因由核心网控制面网元通知给所述锚基站。可选地，所述核心网控制面网元为AMF，锚基站通知第一基站发送携带寻呼原因的寻呼消息之前，AMF通知锚基站寻呼原因。
上述方案中，终端设备接收第一基站发送的寻呼消息，具体是：终端设备的第一通信卡的AS层接收第一基站发送的寻呼消息。这里，寻呼消息中携带有寻呼原因(Paging casue)，其中，寻呼原因用于指示触发寻呼消息的业务或者原因，例如寻呼原因用于指示触发寻呼消息的是语音通话(voice call)业务或者视频通话(video call)业务等。
本申请实施例中，终端设备的第一通信卡的AS层接收第一基站发送的寻呼消息后，可以通过第一通信卡的NAS层基于寻呼消息中的寻呼原因来确定是否响应所述寻呼消息，或者，也可以通过第一通信卡的AS层基于寻呼消息中的寻呼原因来确定是否响应所述寻呼消息。以下分情况进行说明。需要说明的是，以下描述中的AS层是指第一通信卡的AS层，NAS层是指第一通信卡的NAS层。
●情况一：所述终端设备的NAS层基于所述寻呼消息中的寻呼原因，确定是否响应所述寻呼消息。
对于这种情况来说，寻呼原因对于AS层来说是透明的，终端设备的AS层接收第一网络发送的寻呼消息后，将所述寻呼消息中的寻呼原因发送给所述终端设备的NAS层；所述终端设备的NAS层基于所述寻呼原因，确定是否响应所述寻呼消息。例如：若所述寻呼原因指示寻呼由语音业务触发，则确定响应所述寻呼消息，否则，不响应所述寻呼消息。例如：若所述寻呼原因指示寻呼由低优先级的业务触发，则确定不响应所述寻呼消息。
●情况二：所述终端设备的AS层基于所述寻呼消息中的寻呼原因，确定是否响应所述寻呼消息。
对于这种情况来说，寻呼原因对于AS层来说是不透明的，终端设备的AS层接收第一基站发送的寻呼消息后，获取寻呼消息中的寻呼原因；所述终端设备的AS层基于所述寻呼原因，确定是否响应所述寻呼消息。例如：若所述寻呼原因指示寻呼由语音业务触发，则确定响应所述寻呼消息，否则，不响应所述寻呼消息。例如：若所述寻呼原因指示寻呼由低优先级的业务触发，则确定不响应所述寻呼消息。
本申请实施例中，对于处于非激活态的第一通信卡来说，接收到寻呼消息后，终端设备的AS层发起RRC连接恢复过程。具体地，终端设备的AS层向第一基站发送RRC恢复请求消息，其中，若终端设备的NAS层或者AS层确定不响应寻呼消息，则：
1、显式指示方式：所述RRC恢复请求消息携带第二指示信息，所述第二指示信息用于指示所述终端设备不响应寻呼或者指示所述终端设备的繁忙指示。或者，
2、隐式指示方式：所述RRC恢复请求消息对应的公共控制信道(Common Control Channel，CCCH)的第一逻辑信道标识(Logical Channel Identifier，LCID)用于指示所述终端设备不响应寻呼或者指示所述终端设备的繁忙指示。
这里，对于隐式指示方式来说，为CCCH定义一个新的LCID(称为第一LCID)，这个新的LCID用于指示终端设备不响应寻呼或者指示终端设备的繁忙指示。具体地，终端设备通过CCCH发送RRC恢复请求消息(即RRC恢复请求消息承载在CCCH中)，该CCCH的LCID用于指示终端设备不响应寻呼或者指示终端设备的繁忙指示。相应地，所述RRC恢复请求消息在MAC TB中对应的包头为第一包头，所述第一包头中的LCID为所述第一LCID，即：所述RRC恢复请求消息在MAC TB中对应的包括携带所述第一LCID。
步骤202：所述第一基站向所述终端设备发送RRC释放消息，所述终端设备接收所述第一基站发送的RRC释放消息。
在一可选方式中，所述第一基站确认接收到所述终端设备的不响应寻呼指示或者繁忙指示(即所述RRC恢复请求消息所指示的内容)的情况下，向所述终端设备发送RRC释放消息。终端设备接收到RRC释放消息后，即可确定出所述第一基站确认接收到所述终端设备的不响应寻呼指示或者繁忙指示。
在另一可选方式中，所述RRC释放消息携带第一指示信息，所述第一指示信息用于指示确认所述终端设备不响应寻呼或者确认接收到所述终端设备的繁忙指示。这里，所述第一基站确认接收到所述终端设备的不响应寻呼指示或者繁忙指示(即所述RRC恢复请求消息所指示的内容)的情况下， 在向终端设备发送的RRC释放消息中携带所述第一指示信息，终端设备接收到RRC释放消息后，通过第一指示信息确定出所述第一基站确认接收到所述终端设备的不响应寻呼指示或者繁忙指示。
