一种通信方法及装置
相关申请的交叉引用
本申请要求在2019年07月12日提交中国专利局、申请号为201910631842.X、申请名称为“一种通信方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术
随着通信技术的发展，很多终端设备(如手机)都具备双卡双待功能。其中，双卡双待是指一个手机中同时安装两张用户识别模块(subscriber identity module，SIM)卡，这两张SIM卡可以同时在网待机。
其中，双卡双待单通(dual SIM dual standby，DSDS)是一种常见的双卡双待方案。DSDS手机中配置有一套收发射频，在手机待机情况下，两张SIM卡可以分时监听寻呼。但是，由于DSDS手机中仅配置有一套收发射频；因此，DSDS手机仅可以实现双卡双待，而不能实现双卡同时通信。例如，当一个SIM卡使用收发射频进行语音数据传输时，由于该SIM卡完全占用了射频资源，而另一个SIM卡会因为无射频资源可用，导致无法接收到寻呼(paging)请求，从而导致无法接听电话。
为了实现手机的双卡双待双通，双卡双待双通(dual SIM dual active，DSDA)技术被应用于手机。其中，DSDA手机中配置有两套收发射频，即每个SIM都有一套独立的收发射频。如此，即使一个SIM卡使用一套收发射频进行语音数据传输时，另一个SIM卡也可以使用另一套收发射频接收寻呼消息并接听电话。但是，DSDA手机中配置两套收发射频的成本较大，并且，配置两套收发射频会占用较大的布板面积增加手机体积。
目前提出了一种支持双收单发的DSDS(dual receive-DSDS，DR-DSDS)手机。与DSDA手机相比，该DR-DSDS手机中仅配置有一路射频发射(Transmit，Tx)通路和两路射频接收(Receive，Rx)通路，因此可以降低手机成本，减少射频电路对布板面积的占用。然而，由于支持双收单发的手机中仅配置有一路射频发射(Tx)通路，如何实现手机和网络设备之间的有效通信，仍需进一步研究。
发明内容

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地 描述。
首先，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
(1)终端设备：是一种具有无线收发功能的设备，可以部署在陆地上，包括室内或室外、手持、穿戴或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对应用场景不做限定。终端设备有时也可以称为用户设备(user equipment，UE)、移动台和远方站等，本申请的实施例对终端设备所采用的具体技术、设备形态以及名称不做限定。
(2)网络设备：是终端设备通过无线方式接入到该移动通信系统中的接入设备，可以是基站、演进型基站(evolved NodeB，eNodeB)、发送接收点(transmission reception point，TRP)、5G移动通信系统中的下一代基站(next generation NodeB，gNB)、未来移动通信系统中的基站或无线保真(wireless-fidelity，Wi-Fi)系统中的接入节点等；也可以是完成基站部分功能的模块或单元，例如，可以是集中式单元(central unit，CU)，也可以是分布式单元(distributed unit，DU)。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。
(3)本申请实施例中的术语“系统”和“网络”可被互换使用。“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，除非有其它的说明，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，第一指示信息和第二指示信息，只是为了区分不同的指示信息，而并不是表示这两种指示信息的内容、优先级、发送顺序或者重要程度等的不同。
本申请实施例可以应用于各种通信系统，例如：长期演进(long term evolution，LTE)系统、先进的长期演进(advanced long term evolution，LTE-A)系统、第五代(fifth generation，5G)移动通信技术新无线(new radio，NR)系统以及未来可能的通信系统，具体不做限制。
为便于理解本申请实施例，首先以图1a中示出的通信系统为例详细说明适用于本申请实施例的通信系统。图1a为适用于本申请实施例的通信方法的通信系统的示意图。如图1a所示，第一网络中包括网络设备101，第二网络中包括网络设备102，终端设备103可以注册在第一网络和第二网络。示例性地，终端设备103可以具有两个用户身份(比如第一用户身份和第二用户身份)，终端设备103可以以第一用户身份注册在第一网络，以及 以第二用户身份注册在第二网络；或者也可以理解为，终端设备103包括两个用户(比如第一用户和第二用户)，终端设备103的第一用户注册在第一网络，第二用户注册在第二网络。
需要说明的是：(1)图1a中仅是以终端设备具有两个用户身份，并注册在两个网络为例，在其它可能的实施例中，终端设备也可以具有两个以上用户身份，并可以注册在两个以上网络中。本申请实施例将主要基于终端设备具有两个用户身份，并注册在两个网络进行描述，当终端设备具有两个以上用户身份，并注册在两个以上网络时，其具体实现可以参照终端设备具有两个用户身份，并注册在两个网络的相关描述。
(2)本申请实施例中，“用户”(比如第一用户、第二用户)为逻辑概念，“用户”可以对应SIM卡或签约用户信息或虚拟SIM卡或用户标识(如国际移动用户标识(international mobile subscriber identity，IMSI)/临时移动用户标识(temporary mobile subscriber identity，TMSI))，而不仅限于自然人用户或物理终端(手机)等。从网络侧的角度来看，不同的“用户”在逻辑上对应网络侧服务的不同的通信实体。例如，一个具有双注册功能的终端，对于网络侧来说，是两个通信实体。再例如，“用户”对应SIM卡或签约用户信息时，网络侧会将具有不同SIM卡或不同签约用户信息的两个终端识别为两个不同的通信实体，也会将具有多个不同SIM卡或多个签约用户信息的同一终端设备识别为多个不同的通信实体，即使在实际上，具有多个不同SIM卡或多个签约用户信息的终端只是一个物理实体。本申请实施例中将主要以“用户”对应SIM卡为例进行说明。
参见图1b，示出了本申请实施例提供的一种终端设备的结构示意图，该终端设备可以为上述图1a中所示意的终端设备103。如图1b所示，终端设备103可以包括：第一SIM卡接口110、第二SIM卡接口120、与第一SIM卡接口110和第二SIM卡接口120分别耦合的管理器140、与管理器140耦合的处理器130，处理器130连接收发器150。其中，上述处理器130可以为基带处理器(base band processor，BBP)。如图1b所示，收发器150中包括射频Rx1通路、射频Rx2通路和射频Tx通路。其中，上述第一SIM卡接口110用于安装SIM卡1，上述第二SIM卡接口120用于安装SIM卡2。管理器140可以向处理器130发送与SIM卡1的业务相关的上行数据包，或者，发送与SIM卡2的业务相关的上行数据包。相应地，处理器130可以在射频Tx通路发送与SIM卡1的业务相关的上行数据包，或者，与SIM卡2的业务相关的上行数据包。
示例性地，终端设备103可以为能够支持多个运营商的网络制式的终端设备，即终端设备103能够支持多个运营商(如中国联通、中国移动和中国电信中的两个或全部)的网络。以第一SIM卡为例，终端设备103通过获取第一SIM卡的识别码，能够确定第一SIM卡所归属的运营商，进而将第一SIM卡向相应的运营商的网络进行注册。第一SIM卡注册在相应的运营商的网络之后，可以通过随机接入过程接入相应的运营商的网络中的网络设备(比如上述网络设备101)，进而向网络设备101发送业务的上行数据包。以第二SIM卡为例，终端设备103通过获取第二SIM卡的识别码，能够确定第二SIM卡所归属的运营商，进而将第二SIM卡向相应的运营商的网络进行注册。第二SIM卡注册在相应的运营商的网络之后，可以通过随机接入过程接入相应的运营商的网络中的网络设备(比如上述网络设备102)，进而向网络设备102发送业务的上行数据包。
本申请实施例中，射频Tx通路也可以称为Tx射频资源或发射器(Transmitter)，射频Rx通路也可以称为Rx射频资源或接收器(Receiver)，具体不做限定。
针对于图1a和图1b所示意的终端设备，由于其仅具有一路射频Tx通路，因此终端设备在发送与SIM卡1的业务相关的上行数据包时，将无法发送与SIM卡2的业务相关的上行数据包。然而，在一些可能的场景中，比如终端设备正在进行第一SIM卡的语音服务(例如，银行A的热线电话)，同时，还需要通过第二SIM卡打开银行A的应用程序(APP)进行某些操作，也就是说，终端设备在一个时间段内既需要发送与SIM卡1的业务相关的上行数据包，也需要发送与SIM卡2的业务相关的上行数据包；针对于此种场景，一种可能的解决方案为，终端设备在该时间段内分时发送与SIM卡1的业务相关的上行数据包和与SIM卡2的业务相关的上行数据包。举个例子，在某一个时间段(该时间段包括子帧1至子帧5)内，终端设备可以在子帧1、子帧2和子帧3上发送与第一SIM卡的业务相关的上行数据包，以及，在子帧4和子帧5上发送与第二SIM卡的业务相关的上行数据包。通常而言，一个子帧为1ms，一个子帧可以包含多个时隙(slot)，一个时隙可以包含多个更小的时间单位，比如符号(symbol)。
然而，上述解决方案仅是从终端设备自身的角度来协调处理第一SIM卡和第二SIM卡的通信需求，但与终端设备进行通信的网络设备并不感知，从而可能会导致一系列的问题，比如网络设备101和网络设备102可能同时调度终端设备的某一上行时域资源，进而因调度冲突使得终端设备上行传输的误码率较高；但网络设备(比如网络设备101)并不感知调度冲突，可能会认为终端设备的误码率较高是由于其它原因(比如信道环境)等导致的，进而提高发送功率，造成网络资源的浪费。
基于此，本申请实施例将主要研究支持双收单发的终端设备和网络设备之间的通信。
下面对本申请实施例提供的通信方法进行具体描述。
本申请实施例中，终端设备可以注册在第一网络和第二网络，并向第一网络中的网络设备或第二网络中的网络设备发送第一信息，第一信息可以理解为第一指示信息，用于指示终端设备进入第一传输方式或已经进入第一传输方式，或者，第一信息可以包括第一指示信息和第一辅助信息，或者，第一信息包括第一辅助信息。
示例性地，本申请实施例提供的通信方法可以包括三种可能的方案，分别为方案一、方案二和方案三。在方案一中，终端设备向第一网络中的网络设备和/或第二网络中的网络设备发送第一指示信息，第一指示信息用于指示终端设备进入第一传输方式或已经进入第一传输方式；也就是说，终端设备可以通知第一网络和/或第二网络其进入第一传输方式或已经进入第一传输方式，从而使得第一网络中的网络设备和/或第二网络中的网络设备能够根据第一指示信息获知终端设备进入第一传输方式或已经进入第一传输方式，以便于更有效地调度终端设备，实现终端设备和网络设备之间的有效通信。在方案二中，终端设备可以向第一网络中的网络设备发送第一辅助信息，如此，第一网络中的网络设备在终端设备进入第一传输方式后，能够根据第一辅助信息调度终端设备，从而能够提高调度的有效性，实现终端设备和网络设备之间的有效通信。在方案三中，终端设备可以向第一网络中的网络设备发送第二辅助信息，第二辅助信息用于第一网络中的网络设备辅助终端设备随机接入第二网络，从而能够保证终端设备能够顺利地随机接入第二网络，实现终端设备和网络设备之间的有效通信。
示例性地，本申请实施例中所涉及的第一传输方式可以包括终端设备并行处理第一网 络的上行业务和第二网络的上行业务。其中，终端设备并行处理第一网络的上行业务和第二网络的上行业务，可以理解为：终端设备在时域上并行处理第一网络的上行业务和第二网络的上行业务，或者说，终端设备分时处理第一网络的上行业务和第二网络的上行业务。
其中，终端设备处理第一网络的上行业务可以理解为，终端设备向第一网络中的网络设备发送与第一SIM卡的业务相关的上行数据包；同样地，终端设备处理第二网络的上行业务可以理解为，终端设备向第二网络中的网络设备发送与第二SIM卡的业务相关的上行数据包。相应地，终端设备在时域上并行处理第一网络的上行业务和第二网络的上行业务可以理解为，终端设备使用不同的时域资源向第一网络中的网络设备发送与第一SIM卡的业务相关的上行数据包和第二网络中的网络设备发送与第二SIM卡的业务相关的上行数据包。比如，终端设备在子帧1、子帧2和子帧3上向第一网络中的网络设备发送与第一SIM卡的业务相关的上行数据包，以及，在子帧4和子帧5上向第二网络中的网络设备发送与第二SIM卡的业务相关的上行数据包。
需要说明的是，本申请实施例中的第一传输方式，也可以称为双卡并发方式，或双卡并发模式，又或者其它可能的名称，具体不做限定。
基于方案一，图2为本申请实施例提供的一种通信方法所对应的流程示意图，如图2所示，包括：
步骤201，终端设备注册在第一网络和第二网络。
示例性地，终端设备中可以包括第一SIM卡和第二SIM卡，第一SIM卡和第二SIM卡所属的运营商的网络可以相同，也可以不相同。以第一SIM卡和第二SIM卡所属的运营商的网络不同(分别为第一网络和第二网络)为例，第一SIM卡可以注册在第一网络，第二SIM卡可以注册在第二网络。
进一步地，第一SIM卡注册在第一网络后，可以接入第一网络中的网络设备，比如通过随机接入过程接入第一网络中的网络设备a；同样地，第二SIM卡注册在第二网络后，可以接入第二络中的网络设备，比如通过随机接入过程接入第二网络中的网络设备b。
本申请实施例中，终端设备注册在第一网络和第二网络，可以理解为：终端设备已经注册在第一网络和第二网络(即终端设备已经在第一网络和第二网络完成注册)，或者，终端已经注册在第一网络，正在执行第二网络的注册。
步骤202，终端设备向第一网络中的网络设备(为便于描述，下文称为网络设备a)发送第一指示信息，第一指示信息用于指示终端设备进入或已经进入第一传输方式。为便于区分，下文中，终端设备向网络设备a发送的第一指示信息称为第一指示信息a，终端设备向第二网络中的网络设备(称为网络设备b)发送的第一指示信息为第一指示信息b。
相应地，在步骤203中，网络设备a接收第一指示信息a。
在一种可能的示例中，第一指示信息a可以为终端设备向网络设备a发送的一条消息，该条消息可以为新增加的专门用于指示终端设备进入或已经进入第一传输方式的消息，该消息的名称不做限定。在又一种可能的示例中，第一指示信息a可以为终端设备向网络设备a发送的消息中所携带的信息，该消息可以为已有的消息，第一指示信息a可以为该消息中新增加的一个信元；举个例子，第一指示信息a可以包括1个比特位，当该比特位的取值可以为“1”时，指示终端设备进入或已经进入第一传输方式。
本申请实施例中，终端设备在处理第一网络的通信业务时，若符合第一条件，则可以 向网络设备a发送第一指示信息a；其中，符合第一条件包括以下至少一项：(1)终端设备确定需要在第二网络执行RRC连接建立；(2)终端设备确定需要在第二网络执行位置域更新；(3)终端设备确定需要在第二网络发起紧急呼叫；(4)终端设备确定需要在第二网络执行按需系统信息请求；此处，示例性地，在NR系统中，为了减少负载，系统信息(system information，SI)可以不再采用完全广播的方式，而是被分为两大类，即必要系统信息(Minimum SI)(可以理解为系统正常运行所必须的信息)以及其它系统信息(Other SI)，其中部分Other SI将采用按需获取的方式发送，因此，终端设备需要获取部分Other SI时，可以向网络设备发送按需系统信息请求。(5)终端设备确定需要在第二网络执行随机接入。此处所列举的五项仅为示例性说明，在其它可能的实施例中，还可以包括其它可能的内容，具体不做限定。
步骤204，网络设备a根据第一指示信息a进入第一传输方式对应的第二传输方式。
在一种可能的示例中，网络设备a进入第二传输方式可以包括网络设备a提高对终端设备的上行传输的误码率的容忍度，比如网络设备a将终端设备的上行传输的误码率门限由第一数值更新为第二数值，第二数值大于第一数值。本申请实施例中，网络设备a接收到终端设备发送的上行数据后，可以计算上行传输的误码率，若误码率大于误码率门限，则网络设备a在调度终端设备时，会快速降低调制与编码策略(modulation and coding scheme，MCS)索引、提高发送功率，以提高数据传输的准确性。
举个例子，终端设备在未进入第一传输方式时，假设网络设备a调度的时域资源包括子帧1至子帧5，此种情形下，终端设备可以在子帧1至子帧5向网络设备a发送上行数据包。而当终端设备进入第一传输方式后，假设网络设备a调度的时域资源包括子帧1至子帧5，此种情形下，终端设备会在子帧1、子帧2和子帧3上向网络设备a发送与第一SIM卡的业务相关的上行数据包，以及，在子帧4和子帧5上向网络设备b发送与第二SIM卡的业务相关的上行数据包。从网络设备a的角度来看，由于终端设备仅在子帧1、子帧2和子帧3上向网络设备a发送了上行数据包，而在子帧4和子帧5上未向网络设备a发送上行数据包，因此，网络设备a确定出终端设备此次上行传输的误码率较高，大于误码率门限(第一数值)，则网络设备a会快速降低调制与编码策略索引、提高发送功率。实际上，终端设备的上行传输的误码率较高是由于终端设备进入了第一传输方式，而并非是信道环境等原因导致的，此种情形下，网络设备a降低调制与编码策略索引、提高发送功率会造成网络资源的浪费。因此，本申请实施例中，当网络设备a获知终端设备进入第一传输方式后，可以对误码率门限进行更新，从而提高对上行传输的误码率的容忍度，避免网络资源的浪费。
在又一种可能的示例中，网络设备a进入第二传输方式可以包括网络设备a将终端设备配置为预设模式，预设模式可以为预先针对第一传输方式设置的模式，预设模式可以对应一组参数，比如包括调制编码方式、重传次数等。示例性地，预设模式中重传次数的取值为X，而非预设模式中重传次数的取值为Y，其中，X可以大于Y，从而保证终端设备进入第一传输模式后数据的有效传输。本申请实施例中，预设模式所对应的一组参数的具体取值可以由本领域技术人员根据实际需要和经验进行设置。如此，通过将终端设备配置为预设模式，使得网络设备a后续可以基于预设模式来调度终端设备，便于网络设备a和终端设备之间的有效传输。
步骤205，终端设备向网络设备b发送第一指示信息b。
相应地，在步骤206中，网络设备b接收第一指示信息b。
步骤207，网络设备b根据第一指示信息b进入第一传输方式对应的第二传输方式。
此处，步骤205至步骤207的实现可以参照上述步骤202至步骤204。
步骤208，终端设备向网络设备a发送第二指示信息，第二指示信息用于指示终端设备退出或已经退出第一传输方式。为便于区分，下文中，终端设备向网络设备a发送的第二指示信息称为第二指示信息a，终端设备向第二网络中的网络设备(称为网络设备b)发送的第二指示信息为第二指示信息b。
相应地，在步骤209中，网络设备a接收第二指示信息a。
在一种可能的示例中，第二指示信息a可以为终端设备向网络设备a发送的一条消息，该条消息可以为新增加的专门用于指示终端设备退出或已经退出第一传输方式的消息，该消息的名称不做限定。在又一种可能的示例中，第二指示信息a可以为终端设备向网络设备a发送的消息中所携带的信息，该消息可以为已有的消息，第二指示信息a可以为该消息中新增加的一个信元；举个例子，第二指示信息a可以包括1个比特位，当该比特位的取值可以为“0”时，指示终端设备退出或已经退出第一传输方式。
本申请实施例中，终端设备退出第一传输方式的触发条件可以有多种，比如第一网络的上行业务结束和/或第二网络的上行业务结束。
步骤210，网络设备a根据第二指示信息a退出第二传输方式。
在一种可能的示例中，网络设备a退出第二传输方式可以包括网络设备a提高对终端设备的上行传输的误码率的容忍度，比如网络设备a将终端设备的上行传输的误码率门限由第二数值更新为第一数值。在又一种可能的示例中，网络设备a退出第二传输方式可以包括网络设备a将终端设备配置为非预设模式，或者说，网络设备a恢复对终端设备的配置。
步骤211，终端设备向网络设备b发送第二指示信息b，第二指示信息b用于指示终端设备退出或已经退出第一传输方式。
相应地，在步骤212中，网络设备b接收第二指示信息b。
步骤213，网络设备b根据第二指示信息b退出第二传输方式。
此处，步骤211至步骤213的实现可以参照上述步骤208至步骤210。
需要说明的是：图2中的步骤编号仅是为便于描述而进行的编号，并不构成对各个步骤的先后执行顺序的限制；上述各个步骤中没有时序依赖关系的步骤之间没有严格的执行顺序，可根据实际情况调整。图2中的各个步骤也并非执行流程中的必要步骤，具体实施中可以根据实际需要进行删减，比如可以不执行上述步骤205至步骤207以及步骤211至步骤213。
采用方案一中的方法，终端设备向第一网络中的网络设备和/或第二网络中的网络设备发送第一指示信息，使得第一网络中的网络设备和/或第二网络中的网络设备能够获知终端设备进入第一传输方式或已经进入第一传输方式，进而可以有针对性地优化调度策略，实现网络设备和终端设备之间的有效通信，且该实现方式较为简单方便。
也就是说，在方案一中，终端设备粗略辅助，双卡激活即上报指示。示例性地，终端设备确定启动双卡并发模式时，向网络上报简单的指示信息，通知网络终端设备启动了DSDS双卡并发模式。相应地，网络接收终端设备上报的指示信息后，提高对上行误码的容忍度，或者网络就将终端设备重配置为双卡并发模式。进一步地，终端设备确定双卡业 务并发操作结束后，向网络上报指示信息，指示取消双卡并发模式。相应地，网络接收到UE的指示信息后，执行重配置。该方案粗糙简单，网络知道终端设备当前的特殊环境，具体网络如何应对留给网络实现，在这种方法下，性能的保证对网络的调度策略的优化依赖性比较大。
基于方案二，图3为本申请实施例提供的一种通信方法所对应的流程示意图，如图3所示，包括：
步骤301，终端设备注册在第一网络和第二网络。
步骤302，终端设备向第一网络中的网络设备(为便于描述，称为网络设备a)发送第一辅助信息。由于终端设备发送给网络设备a的第一辅助信息和终端设备发送给第二网络中的网络设备(称为网络设备b)的第一辅助信息的内容可能不同，为便于区分，本申请实施例中，将终端设备发送给网络设备a的第一辅助信息称为第一辅助信息a，将终端设备发送给网络设备b的第一辅助信息称为第一辅助信息b。
相应地，在步骤303中，网络设备a接收第一辅助信息a。
步骤304，网络设备a在终端设备进入第一传输方式后，根据第一辅助信息a调度终端设备。
示例性地，第一辅助信息a可以理解为便于网络设备a调度终端设备的辅助信息，比如，第一辅助信息a可以包括至少一项：(1)第一网络和第二网络的定时偏差信息；(2)第二网络的时分双工(time division duplexing，TDD)配置信息；(3)第一资源信息，和/或，第二资源信息；(4)网络设备b对终端设备进行半静态调度的配置信息；(5)第二网络的上行业务的服务质量(quality of service，QoS)信息；(6)第二网络中的网络设备对终端设备进行动态调度的指示信息；(7)终端设备接入第二网络的原因信息；(8)终端设备进入第一传输方式的原因信息。其中，第一资源信息用于指示网络设备a调度终端设备的可用时间单元，第二资源信息用于指示网络设备b调度终端设备的可用时间单元。
下面对第一辅助信息a所包括的内容进行解释说明。
(1)关于第一网络和第二网络的定时偏差信息：在一个示例中，终端设备注册在第一网络和第二网络后，可以主动对第一网络和第二网络的定时偏差进行测量，得到第一网络和第二网络的定时偏差信息。在又一个示例中，由网络设备指示终端设备对第一网络和第二网络的定时偏差进行测量，比如，网络设备a向终端设备发送一个指示信息，终端设备接收到该指示信息后，可以对第一网络和第二网络的定时偏差进行测量，得到第一网络和第二网络的定时偏差信息。
(2)第二网络的TDD配置信息可以是指第二网络的上行/下行(uplink/downlink，UL/DL)配置。以LTE系统为例，针对TDD定义了7种TDD UL/DL配置，如表1所示。
表1：UL/DL配置
Figure PCTCN2020099912-appb-000001
Figure PCTCN2020099912-appb-000002
表1中，“D”代表下行子帧，“U”代表上行子帧，“S”代表特殊子帧。由表1可以看出，LTE TDD系统中，一个无线帧中的子帧可分为三类：下行子帧、上行子帧和特殊子帧，其中，每个特殊子帧由DwPTS(Downlink Pilot Time Slot，下行传输时隙)、GP(Guard Period，保护间隔)和UpPTS(Uplink Pilot Time Slot，上行传输时隙)三部分构成。
在LTE TDD系统中，上下行资源划分是通过上述TDD帧结构的定义实现的，因此针对一个LTE小区可以配置一种TDD帧结构，并可以通过小区中广播的系统信息通知给终端设备。
示例性地，网络设备a接收到第二网络的TDD配置信息后，可以获知第二网络的上下行资源划分，从而避免与网络设备b发生上行调度冲突。
(3)第一资源信息和/或第二资源信息可以是由终端设备确定的，终端设备确定第一资源信息和/或第二资源信息的依据可以有多种，比如第一网络和/或第二网络的TDD配置信息，具体不做限定。举个例子，第一资源信息指示子帧1至子帧4，第二资源信息指示子帧5至子帧8，也就是说，网络设备a可以调度子帧1至子帧4，网络设备b可以调度子帧5至子帧8。
示例性地，网络设备a若接收到第一资源信息(和第二资源信息)，则可以调度第一资源信息所指示的资源，从而避免与网络设备b发生上行调度冲突；或者，网络设备a若接收到第二资源信息，则可以调度第二资源信息所指示的资源以外的资源，从而避免与网络设备b发生上行调度冲突。
本申请实施例中，当终端设备向网络设备a发送第一资源信息和第二资源信息，可以理解为终端设备向网络设备a发送时分复用(time division multiplexing，TDM)模式(TDM pattern)，比如，TDM pattern可以为时隙1至时隙4用于网络设备a调度终端设备，时隙5至时隙8用于网络设备b调度终端设备，或者说，时隙1至时隙4用于SIM卡1的传输，时隙5至时隙8用于SIM卡2的传输。
(4)网络设备b对终端设备进行半静态调度的配置信息可以包括半静态调度的周期、起始偏移和具体的资源位置。
其中，半静态调度也可以称为预配置调度或预配置授权传输(configured grant transmission)。预配置授权传输可以分为两种类型，其中，类型1(Type 1)是指，网络设备通过无线资源控制(radio resource control，RRC)配置周期和起始偏移以及指示具体的资源位置，即可以携带上行授权，除非终端设备收到RRC信令的释放命令，否则可以认为该资源周期性出现。类型2(Type 2)是指，网络设备通过RRC信令配置一个周期和起始偏移，然后通过DCI激活并指示具体的资源位置，除非终端设备收到去激活命令，否则可以认为该DCI指示的资源周期性出现。
示例性地，网络设备a接收到网络设备b对终端设备进行半静态调度的配置信息后，可以更合理地配置对终端设备的半静态调度或动态调度，从而避免与网络设备b发生上行调 度冲突。
需要说明的是，若网络设备b对终端设备的调度类型为半静态调度(比如第二SIM进行语音业务时，网络设备b对终端设备的调度类型可以为半静态调度)，则第一辅助信息a中可以包括该项信息，否则，第一辅助信息a中可以不包括该项信息。
(5)第二网络的上行业务的QoS信息，比如可以包括第二网络的上行业务的时延要求等，具体不做限定。
示例性地，网络设备a接收到第二网络的上行业务的QoS信息后，在调度终端设备时可以考虑第二网络的上行业务的QoS信息，从而保证第二网络的上行业务的正常处理。
(6)第二网络中的网络设备(即网络设备b)对终端设备进行动态调度的指示信息，用于指示网络设备对终端设备的调度是否为动态调度，比如，该指示信息可以包括1个比特位，当比特位的值为“0”时，表示网络设备对终端设备的调度是动态调度，当比特位的值为“1”时，表示网络设备对终端设备的调度不是动态调度。
示例性地，网络设备a接收到网络设备b对终端设备进行动态调度的指示信息后，可以更合理地配置对终端设备的调度。比如若网络设备b对终端设备的调度是动态调度，由于动态调度具有不确定性，因此为了避免冲突，网络设备a可以不对终端设备进行半静态调度。
(7)终端设备进入第二网络的原因信息，例如由于在第二网络需要执行语音或数据业务而接入第二网络，或者由于在第二网络执行位置域更新而接入，或者由于在第二网络发起紧急呼叫而接入，或者由于在第二网络执行按需系统信息请求而接入。
(8)终端设备进入第一传输方式的原因信息，例如由于在第二网络需要执行RRC连接建立，或者由于在第二网络需要执行位置域更新，或者由于在第二网络需要发起紧急呼叫，或者由于在第二网络需要执行按需系统信息请求，或者由于在第二网络需要执行随机接入。
本申请实施例中，第一辅助信息a可以包括上述(1)至(8)中的至少一项，比如，第一辅助信息a可以包括(1)和(2)，或者，第一辅助信息a可以包括(1)和(3)，又或者，第一辅助信息a可以包括(1)和(4)，又或者，第一辅助信息a可以包括(1)、(2)和(5)，又或者，第一辅助信息a可以包括(1)、(3)和(5)，又或者，第一辅助信息a可以包括(1)、(4)和(5)。
本申请实施例中，终端设备向网络设备a发送第一辅助信息a的实现方式可以有多种。
在一种可能的实现方式(实现方式1)中，终端设备若确定进入第一传输方式，则向网络设备a发送第一辅助信息a。在该实现方式的一个示例中，第一辅助信息a可以隐式指示终端设备进入第一传输方式或已经进入第一传输方式，如此，网络设备a接收到第一辅助信息a后，可以确定终端设备进入第一传输方式或已经进入第一传输方式，并根据第一辅助信息a调度终端设备。采用这种隐式指示方式，能够有效节省传输资源。
在该实现方式的又一个示例中，终端设备若确定在第一时刻进入第一传输方式，则可以在第一时刻对应的时间段内向第一网络中的网络设备发送第一辅助信息a，其中，第一时刻对应的时间段为包括所述第一时刻在内的时间段；举个例子，第一时刻为子帧5，第一时刻对应的时间段可以为子帧0至子帧7。也就是说，终端设备若确定在第一时刻进入第一传输方式，则可以在第一时刻之前或之后的一小段时间内上报第一辅助信息a。进一步地，终端设备可以向网络设备a发送第一指示信息，第一指示信息用于指示终端设备进入所述第一传输方式或已经进入第一传输方式。相应地，网络设备接收到第一指示信息后，可以确 定终端设备进入第一传输方式或已经进入第一传输方式，进而可以基于接收到的第一辅助信息a调度终端设备。此种情形下，第一辅助信息a不再隐式指示终端设备进入第一传输方式或已经进入第一传输方式，而是由第一指示信息来指示终端设备进入第一传输方式或已经进入第一传输方式。
在又一种可能的实现方式(实现方式2)中，终端设备向网络设备a发送用于随机接入的第三条消息，第三条消息包括第一辅助信息a。或者，终端设备在成功接入网络设备a后，即向网络设备a发送第一辅助信息a。在该实现方式的一个示例中，第一辅助信息a可以隐式指示终端设备进入第一传输方式或已经进入第一传输方式；在该实现方式的又一个示例中，第一辅助信息a不再隐式指示终端设备进入第一传输方式或已经进入第一传输方式，终端设备还可以向网络设备a发送第一指示信息，第一指示信息用于指示终端设备进入所述第一传输方式或已经进入第一传输方式。相应地，网络设备接收到第一指示信息后，可以确定终端设备进入第一传输方式或已经进入第一传输方式，进而可以基于接收到的第一辅助信息a调度终端设备。
需要说明的是：(1)上述实现方式1和实现方式2仅为两种可能的示例，具体实施中，还可以采用其它可能的实现方式。
(2)假设第一辅助信息a包括第一网络和第二网络的定时偏差信息、第二网络的TDD配置信息，若终端设备先随机接入了网络设备a，后随机接入网络设备b，由于终端设备在随机接入网络设备a时，尚未接入网络设备b，因此可能尚未获取到第二网络的TDD配置信息，此种情形下，终端设备可以在获取到第二网络的TDD配置信息后，再向网络设备a发送第一辅助信息a，比如终端设备可以采用上述实现方式1来向网络设备a发送第一辅助信息a。若终端设备先随机接入了网络设备b，后随机接入网络设备a，由于终端设备在随机接入网络设备a时，已经获取到第二网络的TDD配置信息，因此，终端设备可以采用上述实现方式2来向网络设备a发送第一辅助信息a。
步骤305，终端设备向第二网络中的网络设备(即网络设备b)发送第一辅助信息b。
相应地，在步骤306中，网络设备b接收第一辅助信息b。
步骤307，网络设备b在终端设备进入第一传输方式后，根据第一辅助信息b调度终端设备。
示例性地，第一辅助信息b可以理解为便于网络设备b调度终端设备的辅助信息，比如，第一辅助信息b可以包括至少一项：(1)第一网络和第二网络的定时偏差信息；(2)第一网络的TDD配置信息；(3)第一资源信息，和/或，第二资源信息；(4)网络设备a对终端设备进行半静态调度的配置信息；(5)第一网络的上行业务的服务质量(quality of service，QoS)信息；(6)第一网络中的网络设备对终端设备进行动态调度的指示信息；(7)终端设备进入第一传输方式的原因信息。针对第一辅助信息b所包括的内容的解释可以参照上文对第一辅助信息a所包括的内容的解释说明。示例性地，终端设备向网络设备b发送第一辅助信息b的实现方式可以参照上文终端设备向网络设备a发送第一辅助信息a的实现方式，具体不再赘述。
此处，步骤305至步骤307的实现可以参照上述步骤302至步骤304。
示例性地，针对于上述步骤流程，若终端设备先随机接入了网络设备a，后随机接入网络设备b，则在上述步骤302中，终端设备可以上述实现方式1来向网络设备a发送第一辅助信息a，在步骤305中，终端设备可以上述实现方式2来向网络设备b发送第一辅助信息b。
需要说明的是：图3中的步骤编号仅是为便于描述而进行的编号，并不构成对各个步骤的先后执行顺序的限制；上述各个步骤中没有时序依赖关系的步骤之间没有严格的执行顺序，可根据实际情况调整。图3中的各个步骤也并非执行流程中的必要步骤，具体实施中可以根据实际需要进行删减，比如可以不执行上述步骤305至步骤307。
采用方案二中的方法，终端设备可以向网络设备a发送第一辅助信息a和/或向网络设备b发送第一辅助信息b，从而使得在终端设备进入第一传输方式后，网络设备a可以根据第一辅助信息a调度终端设备和/或网络设备b可以根据第一辅助信息b调度终端设备，能够有效保证终端设备在第一网络和第二网络均获得合适的传输机会，避免第一网络和第二网络的上行调度发生冲突，提高用户体验。
也就是说，在方案二中，终端设备上报第一辅助信息给网络。示例性地，终端设备上报两个运营商的网络的定时偏差信息，可以是终端设备主动执行跨运营商的网络的测量上报，也可以是某个SIM卡或各个SIM卡的网络在DSDS模式下，为终端设备配置执行跨运营商网络测量的配置；或者，终端设备向一个网络上报另一个运营商的网络的TDD配置信息等；或者，终端设备向一个网络上报另一个网络的干扰较强的pattern；或者，终端设备上报终端设备建议两个网络或另一个网络执行调度的TDM pattern，例如建议的TDM pattern可以是slot 1-4子帧用于SIM卡1传输，slot 5-8用于SIM卡2；或者，终端设备上报两个网络各自的业务信息，如QoS信息等，例如卡2可以告诉卡2的基站，希望卡2的基站按照终端设备建议的pattern进行调度。具体地，上述辅助信息可以是在DSDS双卡并发模式激活时向网络上报；或者，也可以是在一个卡进入连接态时就执行上报。相应地，网络获得终端设备上报的上述辅助信息后，例如运营商网络之间的定时偏差信息、终端设备建议的TDM pattern、或者业务信息后，网络可以根据上报的信息执行调度。该方法可以很好地辅助终端设备在两个网络上获得合适的传输机会。
基于方案三，图4为本申请实施例提供的一种通信方法所对应的流程示意图。在方案三中，终端设备可以向第一网络中的网络设备(称为网络设备a)发送第二辅助信息，第二辅助信息用于网络设备a辅助终端设备随机接入第二网络。
示例性地，终端设备随机接入第二网络可以采用多种可能的随机接入流程。其中，一种可能的随机接入流程为四步随机接入流程，四步随机接入流程包括终端设备向网络设备发起随机接入请求(可以称为随机接入消息1)，网络设备向终端设备发送随机接入响应(可以称为随机接入消息2)，终端设备向网络设备发起上行传输(可以称为随机接入消息3，比如对于初始接入，随机接入消息3传输的为RRC连接建立请求)和网络设备向终端设备发送竞争解决消息(可以称为随机接入消息4)。下文中将主要以终端设备采用四步随机接入流程随机接入第二网络为例进行描述。
本申请实施例对第二辅助信息所包括的内容可以不作限定，但凡是能够起到让网络设备a辅助终端设备随机接入第二网络这一作用的信息均在本申请实施例的保护范围之内。
在一个示例(称为示例1)中，第二辅助信息可以包括第二信息和/或第四信息，其中，第二信息包括第三资源信息，第三资源信息用于指示第二网络中的网络设备(称为网络设备b)的随机接入资源，和/或，用于指示终端设备从网络设备b的随机接入资源中选择的部分随机接入资源。第四信息包括第四资源信息，第四资源信息用于指示终端设备从网络设备b获取的传输随机接入消息3的资源。示例性地，网络设备b的随机接入资源可以包 括随机接入的时域资源和/或频域资源，或者说，网络设备b的随机接入资源可以包括随机接入网络设备b的可用的物理随机接入信道(physical random access channel，PRACH)资源，比如PRACH时域资源，举例来说，网络设备b的随机接入资源可以包括PRACH时域资源1、PRACH时域资源2、PRACH时域资源3。
需要说明的是，当第二辅助信息包括第二信息和第四信息时，终端设备可以通过不同的消息向网络设备a发送第二信息和第四信息。
下面以第二辅助信息包括第二信息和第四信息为例，描述一种可能的实现流程，如图4所示，包括：
步骤401，终端设备注册在第一网络和第二网络。
步骤402，终端设备网络设备a发送第二信息，第二信息包括第三资源信息，此处，以第三资源信息用于指示网络设备b的随机接入资源为例。
在一个示例中，若终端设备从网络设备b的随机接入资源中已经选择了一个PRACH时域资源，比如选择了PRACH时域资源2，则第三资源信息还用于指示终端设备从网络设备b的随机接入资源中选择的部分随机接入资源(即PRACH时域资源2)。
相应地，在步骤403中，网络设备a接收第二信息。
步骤404，网络设备a向终端设备发送第三信息，第三信息包括用于指示网络设备a不调度的第一时间单元；第一时间单元包括网络设备b的随机接入资源对应的全部或部分时间单元，或者，第一时间单元包括终端设备选择的部分随机接入资源对应的全部或部分时间单元。其中，时间单元可以为时隙或符号或其它可能的时域粒度，比如当时间单元为时隙时，第一时间单元可以包括一个或多个时隙。
相应地，在步骤405中，终端设备接收网络设备a发送的第三信息。
步骤406，终端设备在第一时间单元内，向网络设备b发送随机接入请求。
针对于步骤404至步骤406，若以第三资源信息指示网络设备b的随机接入资源，则在一种可能的实现方式中，网络设备a接收到第二信息后，若确定可以不调度网络设备b的随机接入资源对应的全部时间单元，则向终端设备发送第三信息，第三信息用于指示第一时间单元，第一时间单元包括网络设备b的随机接入资源对应的全部时间单元(即PRACH时域资源1、PRACH时域资源2、PRACH时域资源3对应的全部时间单元)。相应地，终端设备a接收到第三信息后，可以从PRACH时域资源1、PRACH时域资源2、PRACH时域资源3选择其中的一个PRACH时域资源，并使用选择的PRACH时域资源发送随机接入请求。
在又一种可能的实现方式中，网络设备a接收到第二信息后，若确定可以不调度网络设备b的随机接入资源对应的部分时间单元(比如终端设备需要在PRACH时域资源1对应的时间单元上向网络设备a发送优先级较高的上行数据包，因此网络设备a可以不调度PRACH时域资源2、PRACH时域资源3对应的时间单元，但需调度PRACH时域资源1对应的时间单元)，则向终端设备发送第三信息，第三信息用于指示第一时间单元，第一时间单元网络设备b的随机接入资源对应的部分时间单元(比如PRACH时域资源2、PRACH时域资源3对应的时间单元)。相应地，终端设备a接收到第三信息后，可以从PRACH时域资源2、PRACH时域资源3选择其中的一个PRACH时域资源，并使用选择的PRACH时域资源发送随机接入请求。
可以理解地，若终端设备还向网络设备a发送其已经选择的资源信息(比如PRACH 时域资源2)，则网络设备a可以优先避开PRACH时域资源2，以便于后续终端设备使用PRACH时域资源2发送随机接入请求。
考虑到网络设备b的随机接入资源可以周期性出现，若网络设备a确定不调度网络设备b的随机接入资源对应的全部时间单元，则可以是，网络设备a在多个周期内均不调度这些时间单元；当终端设备随机接入成功后，可以向网络设备a发送指示信息指示随机接入成功，随后网络设备a可以调度这些时间单元。因此，若终端设备的随机接入发生失败，则在重选随机接入资源时，终端设备可以优先选择其之前使用的随机接入资源。比如在一次随机接入中，终端设备使用PRACH时域资源2发送随机接入请求，并发生失败，则在下一次随机接入中，终端设备可以继续使用PRACH时域资源2发送随机接入请求，从而避免终端设备重选其它资源(但网络设备a没有优先避开该资源)可能导致的随机接入失败。
步骤407，网络设备b向终端设备发送随机接入响应。
步骤408，终端设备接收随机接入响应，并向网络设备a发送第四信息，第四信息包括第四资源信息。
示例性地，随机接入响应中可以包括随机接入消息3的上行调度(UL grant)或者说传输随机接入消息3的资源，如此，终端设备接收到随机接入响应后，可以获取到传输随机接入消息3的资源。
相应地，在步骤409中，网络设备a接收第四信息。
步骤410，网络设备a向终端设备发送第五信息，第五信息用于指示网络设备a不调度的第二时间单元；其中，第二时间单元包括传输随机接入消息3的资源对应的全部或部分时间单元。
相应地，在步骤411，终端设备接收网络设备a发送的第五信息。
步骤412，终端设备在第二时间单元内，向网络设备b发送随机接入消息3。
步骤413，网络设备b向终端设备发送随机接入消息4，如此，终端设备随机接入到网络设备b。
在上述示例1中，终端设备可以向网络设备发送第二信息，使得网络设备可以根据第二信息，尝试避开网络设备b的随机接入资源(比如若网络设备a正在使用半静态调度方式进行语音传输，则也可以重配置半静态调度，从而避开网络设备b的随机接入资源或者避开终端设备从网络设备b的随机接入资源中选择的部分随机接入资源)，进一步地，终端设备还可以向网络设备发送第四信息，使得网络设备可以根据第四信息，尝试避开传输随机接入消息3的资源，从而保证终端设备能够顺利地随机接入第二网络。
在又一个示例(称为示例2)中，第二辅助信息用于请求网络设备a挂起第一网络的上行业务，此种情形下，第二信息可以包括挂起指示，进一步地，第二信息还可以包括请求网络设备a挂起第一网络的上行业务的原因信息；其中，该原因信息可以包括：存在第二网络的上行业务或需要处理第二网络的上行业务或终端设备需要在第二网络执行随机接入。相应地，网络设备a接收到第二辅助信息后，可以根据第二辅助信息挂起第一网络的上行业务，并可以获知挂起的原因信息，从而能够使得终端设备优先顺利完成第二网络的随机接入。
需要说明的是：图4中的步骤编号仅是为便于描述而进行的编号，并不构成对各个步骤的先后执行顺序的限制；上述各个步骤中没有时序依赖关系的步骤之间没有严格的执行 顺序，可根据实际情况调整。图4中的各个步骤也并非执行流程中的必要步骤，具体实施中可以根据实际需要进行删减。
采用方案三中的方法，终端设备可以向网络设备a发送第二辅助信息，使得网络设备a能够根据第二辅助信息辅助终端设备随机接入第二网络，以便于保证终端设备能够顺利地随机接入第二网络，实现终端设备和网络设备之间的有效通信。
也就是说，在方案三中，SIM卡2业务激活，触发需要与网络设备b建立连接，因此SIM卡1向网络设备a上报SIM卡2业务激活指示信息，请求网络设备a辅助，为了执行与网络设备b的随机接入过程，终端设备可以辅助上报网络设备b的PRACH配置信息给网络设备a。在一个示例中，网络设备a可以向终端设备发送响应消息，比如，该响应消息可以携带终端设备执行向网络设备b的接入的非调度时隙信息。终端设备执行向网络设备b的接入，如果网络设备a提供辅助接入网络设备b的信息，例如非调度的时隙信息，则终端设备优先在网络设备a的非调度时隙内向网络设备b发起随机接入过程。终端设备建立与网络设备b的RRC连接，并提供必要的辅助信息(如第一辅助信息)；网络设备b获得终端设备上报的上述辅助信息后，例如运营商网络之间的定时偏差信息，终端设备建议的TDM pattern，可以根据终端设备建议的pattern执行调度。或者，网络设备b获得网络设备a的TDD配置信息后，为终端设备配置合适的时隙或符号执行数据传输。
示例性地，终端设备也可以将SIM卡2在网络设备b选择的RA occasions信息上报给网络设备a。进一步地，在后续PRACH资源的重选中，终端设备可以继续选择之前用过的资源。示例性地，随机接入响应中里会有调度随机接入消息3的资源信息和回退(backoff)的指示，终端设备可以将随机接入响应中的信息上报给网络设备a，以便于得到网络设备a的非调度时隙信息。
本申请实施例中，针对于语音业务来说，终端设备在网络设备b发起连接建立前，主动请求当前的SIM卡1网络挂起当前业务，具体请求挂起的原因可以有多种表现形式，优先让SIM卡2完成连接建立过程。a)简单的指示：SIM卡2当前存在业务的指示信息；b)资源类型指示：SIM卡2当前是否使用半永久性调度(semi-persistent scheduling，SPS)或免调度的指示，或具体的资源参数；c)SIM卡2是否为动态调度的指示。d)挂起指示。在上述情况下，如果网络设备a之前使用动态调度模式执行语音传输，则可以重配置为配置的授权(configured grant，CG)或SPS资源的方式。然后，终端设备在SPS或CG传输的空闲期完成网络设备b的接入，终端设备在随机接入资源的选择上需要避开与SPS或CG重叠的时间段。终端设备如果确定在两个网络都可以进行语音业务，则可以上报当前SIM卡1的SPS/CG配置给SIM卡2的网络设备b，以方便SIM卡2的网络配置合适的SPS、CG资源或动态调度的资源。
针对于上述方案一、方案二和方案三，需要说明的是：(1)方案一、方案二和方案三可以分别单独实施，或者也可以结合实施，比如可以将方案一、方案二和方案三中的至少两个方案结合实施。本申请实施例中，方案一、方案二和方案三中的有些内容可以相互参照，比如方案二和方案三中所涉及的终端设备注册在第一网络和第二网络，均可以参照方案一中的描述。针对于方案一至方案三中的每一方案，当有多种可能的实现方式时，本申请实施例仅描述出多种可能的实现方式的区别之处，其它内容可以相互参照。(2)上述方案一、方案二和方案三中主要是以终端设备为支持双SIM卡的终端设备为例进行描述的， 本申请实施例同样适用于其它终端设备连接一个或多个网络中的多个网络设备时的操作。例如，本申请实施例同样适用于支持单SIM卡的终端设备在与两个网络设备连接时，再发起与第三个网络设备的连接建立的场景。
