Description

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09月09日提交中国专利局、申请号为201910849381.3、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)都具备支持多个用户识别模块(subscriber identification module，SIM)卡的功能。以终端设备支持两个SIM卡为例，有多种可能的实现方式，例如双卡单待(dual SIM single standby，DSSS)、双卡双待(dual SIM dual standby，DSDS)、双卡双通(dual SIM dual active，DSDA)。
其中，DSSS表示终端设备中虽然有两个用户身份识别卡(subscriber identification module，SIM)卡，但同一时间只能驻留在一个SIM卡所属的系统中，不同时间可以通过用户选择驻留在不同SIM卡所属的系统中。DSDS表示终端设备可以同时驻留在两个SIM所属的系统中，但同时只能有一个SIM卡所属的系统处于通信状态，例如使用一个SIM卡上网时，不能使用另一个SIM接听电话。DSDA表示终端设备不仅可以同时驻留在多SIM卡所属的系统中，而且可以同时在多个SIM卡所属的系统中进行通信，例如使用一个SIM卡上网时，还可以使用另一个SIM接听电话。
出于成本效率的原因，终端设备的两个SIM卡之间可以共享终端设备的射频资源和/或基带资源，比如终端设备中仅配置有一路射频发射(Transmit，Tx)通路，此种情形下，终端设备的两个SIM卡需要共享射频Tx通路。然而，当终端设备的多个SIM卡之间共享终端设备的射频资源和/或基带资源时，如何实现终端设备和网络设备之间的有效通信，仍需进一步研究。
发明内容
有鉴于此，本申请提供了一种通信方法及装置，用以实现终端设备和网络设备之间的有效通信，提高传输性能。

需要说明的是：(1)图1a中仅是以终端设备支持两个用户身份，并注册在两个网络为例，在其它可能的实施例中，终端设备也可以支持两个以上用户身份，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支持两个用户身份，并注册在两个网络进行描述，当终端设备支持两个以上用户身份，并注册在两个以上网络时，其具体实现可以参照终端设备支持两个用户身份，并注册在两个网络的相关描述。
(2)本申请实施例中，“用户身份”(比如第一用户身份、第二用户身份)为逻辑概念，比如，“用户身份”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))。从网络侧的角度来看，不同“用户身份”在逻辑上对应网络侧服务的不同通信实体，例如一个支持两个用户身份的终端设备，对于 网络侧来说，是两个通信实体。再例如，“用户身份”对应SIM卡或签约用户信息时，网络侧会将支持不同SIM卡或不同签约用户信息的两个终端设备识别为两个不同的通信实体，也会将支持多个不同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，支持多个不同SIM卡或多个签约用户信息的终端设备只是一个物理实体。本申请实施例中将主要以“用户身份”对应SIM卡为例进行说明。
示例性地，SIM卡可以理解为终端设备接入移动网络的钥匙，为了便于描述，本申请实施例中将SIM卡以及其演进都统称为SIM卡。比如SIM卡可以是全球移动通信系统(global system for mobile communications，GSM)数字移动电话用户的身份识别卡，用于存储用户的身份识别码和密钥，并支持GSM系统对用户的鉴权；又比如，SIM卡也可以是全球用户识别卡(universal subscriber identity module，USIM)，也可以称为升级SIM卡。
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中包括射频接收Rx1通路和射频发射Tx1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。处理器130可以从管理器140获取与SIM卡1相关的信息和/或与SIM卡2相关的信息，其中，与SIM卡1相关的信息可以包括SIM卡1对应的用户身份信息，与SIM卡2相关的信息可以包括SIM卡2对应的用户身份信息。示例性地，处理器130可以根据与SIM卡1相关的信息，在射频Tx1通路上发送与SIM卡1的业务相关的上行数据包，或者，处理器130可以根据与SIM卡2相关的信息，在射频Tx1通路上发送与SIM卡2的业务相关的上行数据包。以及，处理器130可以在射频Rx1通路上接收与SIM卡1的业务相关的下行数据包，或者，接收与SIM卡2的业务相关的下行数据包。参见图1c所示，为图1b的简化示意图。此种情形下，可以理解为SIM卡1和SIM卡2共享射频Rx1通路或射频Tx1通路。
参见图1d，示出了本申请实施例提供的又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。图1d所示意的终端设备的结构与图1b所示意的终端设备的结构的差异之处在于，图1d中，收发器150中包括射频Rx1通路、射频Rx2通路和射频Tx1通路。示例性地，处理器130可以在射频Tx1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。参见图1e所示，为图1d的简化示意图，补充体现了天线个数的差异。此种情形下，可以理解为第一SIM卡和第二SIM卡有单独的接收射频通路(比如第一SIM卡对应射频Rx1通路，第二SIM卡对应射频Rx2通路)，但共享射频Tx1通路。
参见图1f，示出了本申请实施例提供的又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。图1f所示意的终端设备的结构与图1b所示意的终端设备的结构的差异之处在于，图1f中，收发器150中包括射频Rx1通路、射频Rx2通路、射频Tx1通路和射频Tx2通路。示例性地，处理器130可以在射频Tx1通路和射频Tx2通路发送与SIM卡1的业务相关的上行数据包，或者，在射频Tx2通路发送与SIM卡2的业务相关的上行数据包。参见图1g所示，为图1f的简化示意图，补充体现了天线个数的差异。此种情形下，可以理解为第一SIM卡和第二SIM卡有单独的接收射频通路 (比如第一SIM卡对应射频Rx1通路，第二SIM卡对应射频Rx2通路)，但共享其中一个射频Tx通路，比如共享射频Tx2通路。
由于终端设备的结构的多样性，在一个示例中，终端设备中的射频通路和天线可以具有对应关系，此种情形下，当终端设备使用某一射频通路时，可以使用该射频通路对应的天线。在又一个示例中，终端设备中的射频通路和天线也可以不具有对应关系，此种情形下，当终端设备使用不同的射频通路时，可以使用相同的天线或不同的天线。为便于说明，本申请实施例中统一从射频通路的角度来进行描述，当终端设备中的射频通路和天线不具有对应关系时，下文中所涉及的射频通路也可以替换为天线。
本申请实施例中，射频Tx通路也可以称为发射射频资源或发射器(Transmitter)，射频Rx通路也可以称为接收射频资源或接收器(Receiver)，具体不做限定。
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SIM卡1为例，终端设备103通过获取SIM卡1的识别码，能够确定SIM卡1所归属的运营商，进而以SIM卡1对应的用户身份(比如第一用户身份)向相应的运营商的网络进行注册(也可以简述为SIM卡1注册到通信网络)。注册成功之后，终端设备103可以以SIM卡1对应的用户身份发起随机接入过程，并接入相应的运营商的网络中的网络设备(比如上述第一网络中的网络设备101)，进入连接状态，进而向网络设备101发送业务的上行数据包，以及接收网络设备101发送的下行数据包。以SIM卡2为例，终端设备103通过获取SIM卡2的识别码，能够确定SIM卡2所归属的运营商，进而以SIM卡2对应的用户身份(比如第二用户身份)向相应的运营商的网络进行注册。注册成功之后，终端设备103可以以SIM卡2对应的用户身份发起随机接入过程，并接入相应的运营商的网络中的网络设备(比如上述第二网络中的网络设备102)，进入连接状态，进而向网络设备102发送业务的上行数据包，以及接收网络设备101发送的下行数据包。
以图1b和图1c所示意的情形为例，在终端设备103与第一网络建立有无线资源控制(radio resource control，RRC)连接的场景中，当终端设备103在第二网络中处于RRC idle状态且决定接收或响应第二网络中的寻呼时或者当终端设备103需要在第二网络中执行某些信令活动(例如，周期性移动性注册更新)时，终端设备103需要停止第一网络中的部分当前活动，比如终端设备103可以自主地释放与第一网络的RRC连接并且离开第一网络，或者，在不释放RRC连接或RRC连接挂起时停止与第一网络的通信。参见图1h所示，当终端设备接收第二网络中的数据时，会导致无法接收第一网络中的数据，进而使得第一网络与终端设备之间的通信发生中断。此时，很可能扭曲第一网络中的统计数据，进而误导依赖这些统计数据的算法。此外，在终端设备103与第一网络之间的通信发生中断期间，第一网络可能会继续寻呼终端设备103，从而导致寻呼资源的浪费。
基于此，本申请实施例提供一种通信方法，通过终端设备以第一用户身份向第一网络设备通知第一网络设备终端设备的射频资源和/或基带处理资源在不同SIM卡之间的切换的相关信息，即使得第一网络设备获知支持多SIM卡的终端设备在协调多SIM卡通信过程中的一些行为，从而能够提高网络侧对支持多SIM卡的终端设备的行为的可知性，改变了现有技术中网络侧对支持多SIM卡的终端设备的行为的不可知状态，能够有效降低网络侧对终端设备的行为的误统计，实现终端设备与网络设备之间的有效通信，改善网络的系统性能。

进一步地，SIM卡1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设备，进而终端设备在SIM卡1所属的网络的状态为RRC连接(RRC_Connected)态。
步骤202，终端设备以第一用户身份向第一网络设备发送第一信息。
本申请实施例中，第一信息可以为SIM卡自适应信息(SIM adaptation indication，SAI)或者其它可能的名称，具体不作限定。
示例性地，第一信息可以包括资源切换指示信息、第二指示信息、第六指示信息中的至少一项。其中，资源切换指示信息也可以称为能力协调信息，或者具有其它可能的名称，具体不做限定；资源切换指示信息可以包括第一指示信息或第五指示信息，比如第一指示信息可以用于指示终端设备以第一用户身份无法使用第一资源与第一网络设备进行通信(或者说终端设备以第一用户身份与第一网络设备进行通信无法使用第一资源，可以理解为终端设备在第一用户身份所属的网络中不具有使用第一资源的能力)，第五指示信息可以用于指示终端设备以第一用户身份与第一网络设备进行通信能够使用第一资源(或者说终端设备以第一用户身份与第一网络设备进行通信能够使用第一资源，可以理解为终端设备在第一用户身份所属的网络中具有使用第一资源的能力)，其中，第一资源包括：终端设备的部分或全部射频资源，和/或，终端设备的部分或全部基带资源。第二指示信息用于指示第一时长，第一时长为终端设备以第一用户身份与第一网络设备进行通信无法使用第一资源所需的时长。示例性地，第一时长的单位可以为时间单元，时间单元可以为时隙、符号、子帧、时隙组、符号组、子帧组中的任一项，具体不做限定；其中，时隙组可以包括一个或多个时隙，符号组可以包括一个或多个符号，子帧组可以包括一个或多个子帧。以第一时长的单位为时隙(slot)为例，此种情形下，第一时长可以为一个或多个时隙。第六指示信息用于指示终端设备是否需要以第二用户身份使用第一资源向第二网络设备发起随机接入。也就是说，在一个示例中，第一信息可以包括第一指示信息，还可以包括第二指示信息和/或第六指示信息；在又一个示例中，第一信息可以包括第五指示信息。
示例性地，射频资源可以包括发射射频资源和/或接收射频资源，比如在上述图1b和图1c所示意的情形中，终端设备的全部射频资源包括射频Tx1通路、射频Rx1通路；在上述图1d和图1e所示意的情形中，终端设备的全部射频资源包括射频Rx1通路、射频Rx2通路和射频Tx1通路；在上述图1f和图1g所示意的情形中，终端设备的全部射频资源包括射频Rx1通路、射频Rx2通路、射频Tx1通路和射频Tx2通路。基带资源(也可以称为基带处理资源)可以包括与射频接收通路或射频发射通路相关联的基带控制或基带处理资源，比如射频接收通路或射频发射通路的开关控制、接收数据的基带滤波、数字信 号处理、发送数据的基带变换等。
本申请实施例中，第一指示信息用于指示终端设备以第一用户身份无法使用第一资源与第一网络设备进行通信。示例性地，第一指示信息指示终端设备以第一用户身份无法使用第一资源与第一网络设备进行通信的实现方式可以有多种，比如，第一指示信息可以指示第一资源由第一状态切换为第二状态，进而隐式指示出终端设备以第一用户身份无法使用第一资源与第一网络设备进行通信。其中，第一资源处于第一状态时，第一资源用于终端设备以第一用户身份与第一网络设备进行通信，即终端设备以第一用户身份能够使用第一资源与第一网络设备进行通信；第一资源处于第二状态时，第一资源用于终端设备以第二用户身份与第二网络设备进行通信，即终端设备以第一用户身份无法使用第一资源与第一网络设备进行通信。也就是说，若第一指示信息指示第一资源由第一状态切换为第二状态，则说明终端设备以第一用户身份无法使用第一资源与第一网络设备进行通信。比如，在上述图1b和图1c所示意的情形中，第一资源可以包括射频Tx1通路和/或射频Rx1通路；在上述图1d和图1e所示意的情形中，第一资源可以包括射频Tx1通路；在上述图1f和图1g所示意的情形中，第一资源可以包括射频Tx2通路。
第五指示信息用于指示终端设备以第一用户身份能够使用第一资源与第一网络设备进行通信。示例性地，第五指示信息指示终端设备以第一用户身份能够使用第一资源与第一网络设备进行通信的实现方式可以有多种，比如，第五指示信息可以指示第一资源由第二状态切换为第一状态，进而隐式指示出终端设备以第一用户身份能够使用第一资源与第一网络设备进行通信。
针对于资源切换指示信息，在一个示例中，以图1b和图1c所示意的情形为例，资源切换指示信息可以包括3个比特，下面结合表1描述3个比特的不同取值所表示的含义。

Figure PCTCN2020113828-appb-000002
表3中，若终端设备以第一用户身份向第一网络设备发送第一指示信息(或者也可以称为资源切换指示信息1)，则第一指示信息中2个比特的取值可以为01；若终端设备以第一用户身份向第一网络设备发送第五指示信息(或者也可以称为资源切换指示信息2)，则第五指示信息中2个比特的取值可以为10。需要说明的是，表3仅是2个比特的不同取值所表示的含义的一种可能的情形示例，具体不做限定。
针对于第二指示信息，在一个示例中，第二指示信息可以指示时间单元的个数，比如时隙的个数。举个例子，第二指示信息包括3个比特，当3个比特的取值为非0时，其所指示的值代表时隙个数，比如001代表1个时隙，010代表2个时隙，具体不做限定。示 例性地，当3个比特的取值为000时，其可以代表终端设备以第一用户身份与第一网络设备进行通信无法使用第一资源所需的时长为不确定的时长。
在又一个示例中，可以预先配置多个可能的时长，比如预先配置4个可能的时长(时长1、时长2、时长3和时长4)，则第二指示信息可以包括2个比特，2个比特的一种取值对应一种预先配置的时长，参见表4所示。

针对于第六指示信息，在一个示例中，第六指示信息可以包括1个比特，当该1个比特的取值为1时，代表终端设备需要以第二用户身份使用所述第一资源向第二网络设备发起随机接入；当该1个比特的取值为0时，代表终端设备不需要以第二用户身份使用所述第一资源向第二网络设备发起随机接入。
本申请实施例中，终端设备以第一用户身份向第一网络设备发送第一信息的实现方式可以有多种，下面描述3种可能的实现方式(参见实现方式1、实现方式2和实现方式3)。
在一种可能的实现方式(称为实现方式1)中，终端设备以第一用户身份使用上行控制信道资源向第一网络设备发送第一信息。其中，上行控制信道资源可以为物理上行控制信道(physical uplink control channel，PUCCH)资源(或者也可以称为PUCCH占用的资源)。
在该实现方式的一个示例中，PUCCH资源可以为第一网络设备专门为第一信息分配的上行资源，此种情形下，第一信息在PUCCH资源上单独传输。在该实现方式的又一个示例中，PUCCH资源可以为第一网络设备为现有的上行控制信息(uplink control information，UCI)分配的上行资源，现有的UCI可以包括调度请求(scheduling request，SR)、混合自动重传请求(hybrid automatic repeat request，HARQ)反馈信息、信道状态信息(channel state information，CSI)。此种情形下，第一信息和现有的UCI可以在PUCCH资源上联合传输。以现有的UCI包括混合自动重传请求(hybrid automatic repeat request，HARQ)反馈信息为例，第一信息和HARQ反馈信息在PUCCH资源上联合传输可以理解为：(1)通过打孔(puncture)的方式在PUCCH资源上发送第一信息和HARQ反馈信息，此时，HARQ反馈信息和第一信息可以独立编码，其中，HARQ反馈信息的编码参数可以和在PUCCH资源上单独发送HARQ反馈信息时的编码参数相同；或者，(2)通过速率匹配的方式在PUCCH资源上发送第一信息和HARQ反馈信息，此时，HARQ反馈信息和第一信息可以独立编码，其中，HARQ反馈信息的编码参数和在PUCCH资源上单独发送HARQ反馈信息时的编码参数不同，且HARQ反馈信息和第一信息可以具有不同的功控或 编码(例如速率匹配)参数；或者，(3)HARQ反馈信息和第一信息进行联合编码，并在PUCCH资源上发送联合编码后的信息。
比如，当第一用户身份对应的HARQ码本(codebook)为类型1(Type1)HARQ codebook(半静态HARQ码本)或Type2HARQ codebook(动态HARQ码本)时，可以在HARQ码本前面或后面增加第一信息的信息比特。示例性地，第一信息和HARQ反馈信息可以具有相同的优先级，或第一信息具有比HARQ反馈信息更高的优先级。采用这种方式，终端设备可以在第一网络设备为终端设备的HARQ反馈信息分配的上行资源上发送第一信息，从而能够有效节省上行信息的传输资源。
示例性地，可以由第一网络设备通过配置确定第一信息是否可以和UCI(比如HARQ反馈信息)进行联合传输。比如第一网络设备向终端设备发送第七指示信息，第七指示信息用于指示终端设备使用PUCCH资源联合发送第一信息和UCI；相应地，终端设备接收到第七指示信息后，可以使用PUCCH资源联合发送第一信息和UCI。
在又一种可能的实现方式(称为实现方式2)中，终端设备以第一用户身份使用上行数据信道资源向第一网络设备发送第一信息。其中，上行数据信道资源可以为物理上行共享信道(physical uplink shared channel，PUSCH)资源(或者也可以称为PUSCH占用的资源)。
在该实现方式的一个示例中，PUSCH资源可以为第一网络设备专门为第一信息分配的上行资源，此种情形下，第一信息在PUSCH资源上单独传输。在该实现方式的又一个示例中，PUSCH资源可以为第一网络设备为上行数据信息分配的上行资源，此种情形下，第一信息和上行数据信息可以在PUSCH资源上联合传输。其中，第一信息和上行数据信息在PUSCH资源上联合传输可以理解为：(1)通过打孔的方式发送第一信息和上行数据信息；或者，(2)通过速率匹配的方式发送第一信息和上行数据信息；或者，(3)第一信息和上行数据信息进行联合编码，并在PUSCH资源上发送联合编码后的信息。
示例性地，可以由第一网络设备通过配置确定第一信息是否可以和上行数据信息进行联合传输。比如第一网络设备向终端设备发送第八指示信息，第八指示信息用于指示终端设备使用PUSCH资源发送第一信息和上行数据信息；相应地，终端设备接收到第八指示信息后，可以使用PUSCH资源联合发送第一信息和上行数据信息。
针对于上述实现方式1和实现方式2，需要说明的是，(1)当终端设备正在以第一用户身份进行下行数据传输(即具有PUCCH资源)时，终端设备可以采用上述实现方式1来发送第一信息；当终端设备正在以第一用户身份进行上行数据传输(即具有PUSCH资源)时，终端设备可以采用上述实现方式2来发送第一信息；当终端设备正在以第一用户身份进行下行数据传输以及以以第一用户身份进行上行数据传输(即同时具有PUCCH资源和PUSCH资源)时，终端设备可以使用其中一个资源进行上报，或者根据一定的准则分别在PUCCH资源和PUSCH资源上发送第一信息。
(2)当终端设备采用上述方式1来发送第一信息时，终端设备可以周期性地发送第一信息。举例来说，PUCCH资源可以为周期性资源，第一网络设备可以为终端设备配置PUCCH资源信息，比如PUCCH资源信息可以包含PUCCH资源的起始时间信息以及周期；相应地，终端设备获取配置的PUCCH资源信息后可以判断周期性的传输时机，并在传输时机上发送第一信息。也就是说，终端设备可以周期性或非周期性发送第一信息：当终端设备周期性发送第一信息时，可以使用PUCCH资源；当终端设备非周期性发送第一信息 时，可以使用PUSCH资源。
在又一种可能的实现方式(称为实现方式3)中，终端设备以第一用户身份向第一网络设备发送媒体接入控制单元(medium access control，MAC)控制单元(control element，CE)，MAC CE包括第一信息。此处的MAC CE可以为本申请实施例新定义的一个MAC CE，通过新定义的一个MAC CE来发送第一信息，信息扩展较为方便，且对标准的影响较小。
示例性地，MAC PDU由一个或多个MAC子PDU(subPDU)组成。每个MAC subPDU包含以下之一：仅MAC子头(包括填充)；MAC子头和MAC SDU；MAC子头和MAC CE；MAC子头和填充。每个MAC子头对应于MAC SDU、MAC CE或填充。在一个示例中，MAC子头由四个头字段R/F/LCID/L组成，该种情形主要是针对于除固定大小的MAC CE、填充和包含上行公共控制信道(uplink common control channel，UL CCCH)的MAC SDU之外的MAC子头；在又一个示例中，MAC子头由两个头字段R/LCID组成，该种情形主要是针对于固定大小的MAC CE、填充和包含UL CCCH的MAC SDU的MAC子头。其中，LCID为逻辑信道ID，表示相应MAC SDU的逻辑信道实例或相应MAC CE或填充的类型，每个MAC子头有一个LCID字段，LCID字段大小为6位；L为长度字段，表示相应MAC SDU或可变大小MAC CE的长度(以字节为单位)，除了对应于固定大小的MAC CE、填充和包含UL CCCH的MAC SDU的MAC子头之外，每个MAC子头有一个L字段，L字段的大小由F字段表示；F为格式字段，表示长度字段的大小。除了对应于固定大小的MAC CE，填充和包含UL CCCH的MAC SDU的子头之外，每个MAC子头有一个F字段。F字段的大小是1位，当取值为0时，表示长度字段为8位，当取值为1时，表示长度字段为16位；R为保留位，设置为0。
本申请实施例新定义的MAC CE对应的MAC子头中包括LCID，所述LCID用于指示该MAC CE包括第一信息。在一个示例中，LCID的取值可以为33～51中的任一个值，具体不做限定。示例性地，该MAC CE可以作为单独的MAC PDU进行发送，也可以和其他的MAC SDU一起发送，具体不做限定。
示例性地，本申请实施例新定义的MAC CE可以为固定长度的MAC CE或者也可以为可变长度的MAC CE。在一个示例中，参见图3a所示，为固定长度为1个字节的MAC CE，可以包括R、A、自适应持续时长(Adaptation duration)、自适应项目(Adaptation Item)，其中，R代表保留比特，A代表第六指示信息，Adaptation duration代表第二指示信息，AdaptationItem代表资源切换指示信息。在又一个示例中，参见图3b所示，为固定长度为1个字节的MAC CE，可以包括R、A、Adaptation duration、D、Adaptation Item，其中，R代表保留比特，A代表第六指示信息，Adaptation duration代表第二指示信息，D和Adaptation Item代表资源切换指示信息。以上述表2b所示意的情形为例，D可以为一个比特，用于指示切换方向，当D的取值为1时，表示切出，当D的取值为0时，表示切回。
需要说明的是，当第一信息中包括第一指示信息、第二指示信息和第六指示信息时，终端设备可以通过一条消息来发送第一指示信息、第二指示信息和第六指示信息，或者，也可以通过不同的消息来发送第一指示信息、第二指示信息和第六指示信息。比如，终端设备可以通过PUCCH(或PUSCH)资源1上承载的消息1来发送第一指示信息、第二指示信息和第六指示信息；或者，终端设备也可以通过PUCCH(或PUSCH)资源1上承载的消息1来发送第一指示信息，以及通过PUCCH(或PUSCH)资源2上承载的消息2来发送第二指示信息和第六指示信息；又或者，终端设备也可以通过PUCCH(或PUSCH)资源1上 承载的消息1来发送第一指示信息，通过PUCCH(或PUSCH资源2)上承载的消息2来发送第二指示信息，以及通过PDCCH(或PUSCH)资源3上承载的消息3来发送第六指示信息。
本申请实施例中，通过终端设备向第一网络设备发送第一信息，使得第一网络设备获知终端设备的射频资源和/或基带处理资源在不同SIM卡之间的切换，即使得第一网络设备明确支持多SIM卡的终端设备在协调多SIM卡通信过程中的一些行为，从而能够提高网络侧对支持多SIM卡的终端设备的行为的可知性，改变了现有技术中网络侧对支持多SIM卡的终端设备的行为的不可知状态，能够有效降低网络侧对终端设备的行为的误统计，实现终端设备与网络设备之间的有效通信，改善网络的系统性能。
在一个示例中，步骤202中终端设备以第一用户身份向第一网络设备发送的第一信息可以包括第一指示信息，示例性地，还可以包括第二指示信息和/或第三指示信息，比如若终端设备需在SIM卡2上进行有规律的发送和/或接收处理(例如寻呼接收或邻区测量)，则第一信息中可以包括第二指示信息。
本申请实施例中，终端设备以第一用户身份向第一网络设备发送第一指示信息的触发原因可以有多种。比如，终端设备在SIM卡1所在系统的状态为RRC_Connected，在SIM卡2所在系统的状态为无线资源控制空闲态(RRC_Idle)，当终端设备需要以第二用户身份接收寻呼消息或随机接入第二网络设备时，终端设备可以以第一用户身份向第一网络设备发送第一指示信息；又比如，终端设备在SIM卡1所在系统的状态为RRC_Connected，在SIM卡2所在系统的状态为无线资源控制去活动态(RRC_inactive)，当终端设备需要以第二用户身份与第二网络设备进行数据传输时，终端设备可以以第一用户身份向第一网络设备发送第一指示信息。
步骤203，第一网络设备向终端设备发送第三指示信息和/或第四指示信息。
相应地，在步骤204中，终端设备接收第一网络设备发送的第三指示信息和/或第四指示信息。其中，第三指示信息用于指示第二资源，第二资源包括用于终端设备以第一用户身份与第一网络设备进行通信的射频资源和/或基带处理资源；第四指示信息用于指示第二时长，第二时长为允许终端设备以第一用户身份与第一网络设备进行通信无法使用第一资源的时长。
步骤205，终端设备以第一用户身份向第一网络设备发送第五指示信息，第五指示信息用于指示终端设备以第一用户身份与第一网络设备进行通信能够使用第一资源。
相应地，在步骤206中，第一网络设备接收终端设备以第一用户身份发送的第五指示信息。
示例性地，终端设备若确定终端设备以第一用户身份无法使用第一资源与所述第一网络设备进行通信的时长大于或等于第三时长，则向第一网络设备发送第五指示信息。在一个示例中，若终端设备接收到第一网络设备发送的第四指示信息，则第三时长可以等于第四指示信息所指示的第二时长；若终端设备未接收到第一网络设备发送的第四指示信息(或者说第一网络设备未向终端设备发送第四指示信息)，且第一信息中包括第二指示信息，则第三时长可以等于第二指示信息所指示的第一时长。
本申请实施例中，上述步骤203至步骤206为可选步骤，也就是说，在具体实施中，步骤203至步骤206可以执行或者也可以不执行。下面分别针对实现方式1和实现方式2描述几种可能的示例，以说明执行步骤203至步骤206中的部分或全部步骤的情形。
在一种可能的实现方式(称为实现方式1)中，终端设备以第一用户身份向第一网络设备发送第一信息后，可以无需等待第一网络设备的响应，而直接基于第一信息进行相应的操作。采用这种方式，由于终端设备无需等待第一网络设备的响应，从而能够有效节省终端设备和第一网络设备之间的信息交互，进而节省传输资源。
下面结合场景1描述该实现方式的几种示例，其中，场景1是指：以上述图1d和图1e所示意的情形为例，终端设备以第一用户身份使用射频Tx1通路与第一网络设备进行通信，假定第一信息包括第一指示信息(指示射频Tx1通路切出)和第二指示信息(指示第一时长为3个时隙)。
基于上述场景1，在该实现方式的一个示例中，终端设备以第一用户身份向第一网络设备发送第一信息后，可以直接将射频Tx1通路切出；若确定射频Tx1通路切出的时长达到第一时长(如3个时隙)，则将射频Tx1通路切回；进一步地，终端设备可以以第一用户身份向第一网络设备发送第五指示信息，或者，也可以不以第一用户身份向第一网络设备发送第五指示信息。需要说明的是，在该示例中，若场景1中所假定的第一信息包括第一指示信息而不包括第二指示信息，则终端设备将射频Tx1通路切回后，可以以第一用户身份向第一网络设备发送第五指示信息。在该示例中，未执行步骤203和步骤204；是否需要执行步骤205和步骤206可以取决于第一信息所包括的内容，比如若第一信息包括第二指示信息，则可以执行或者也可以不执行步骤205和步骤206，若第一信息不包括第二指示信息，则需要执行步骤205和步骤206。
基于上述场景1，在该实现方式的又一个示例中，终端设备以第一用户身份向第一网络设备发送第一信息后，可以直接将射频Tx1通路切出；相应地，第一网络设备接收到第一信息后，可以向终端设备发送第四指示信息(指示第二时长为2个时隙)。终端设备接收到第一网络设备发送的第四指示信息后，若确定射频Tx1通路切出的时长达到第二时长(即2个时隙)，则将射频Tx1通路切回；进一步地，终端设备可以以第一用户身份向第一网络设备发送第五指示信息，或者，也可以不以第一用户身份向第一网络设备发送第五指示信息。在该示例中，执行了步骤203和步骤204；可以执行或者也可以不执行步骤205和步骤206。
在又一种可能的实现方式(称为实现方式2)中，终端设备以第一用户身份向第一网络设备发送第一信息后，需要等待第一网络设备的响应，并基于第一网络设备的响应执行相应的操作。采用这种方式，由于终端设备需要等待第一网络设备的响应来执行相应的操作，从而使得第一网络设备可以控制终端设备的操作，有利于保证业务的正常执行。
下面结合场景1描述该实现方式的几种示例。
基于上述场景1，在该实现方式的一个示例中，终端设备以第一用户身份向第一网络设备发送第一信息，相应地，第一网络设备接收到第一信息后，若拒绝射频Tx1通路切出，则可以不向终端设备发送相应的响应。进而，终端设备若在设定时间段内未接收到第一网络设备的响应，则获知第一网络设备拒绝射频Tx1通路切出，此时，终端设备不再将射频Tx1通路切出。其中，设定时间段可以由本领域技术人员根据经验和实际需要来设置，具体不做限定。在该示例中，未执行步骤203至步骤206。
基于上述场景1，在该实现方式的又一个示例中，终端设备以第一用户身份向第一网络设备发送第一信息，相应地，第一网络设备接收到第一信息后，若拒绝射频Tx1通路切出，则可以向终端设备发送第三指示信息，第三指示信息指示的第二资源包括射频Tx1 通路。进而，终端设备接收到第一网络设备发送的第三指示信息后，获知第一网络设备拒绝射频Tx1通路切出，此时，终端设备不再将射频Tx1通路切出。在该示例中，执行了步骤203和步骤204；未执行步骤205和步骤206。
基于上述场景1，在该实现方式的又一个示例中，终端设备以第一用户身份向第一网络设备发送第一信息，相应地，第一网络设备接收到第一信息后，若同意射频Tx1通路切出，则可以向终端设备发送第四指示信息(指示第二时长为2个时隙)。终端设备接收到第一网络设备发送的第四指示信息后，将射频Tx1通路切出。终端设备若确定射频Tx1通路切出的时长达到第二时长(即2个时隙)，则将射频Tx1通路切回；进一步地，终端设备可以以第一用户身份向第一网络设备发送第五指示信息，或者，也可以不以第一用户身份向第一网络设备发送第五指示信息。在该示例中，执行了步骤203和步骤204；可以执行或者也可以不执行步骤205和步骤206。
下面结合场景2描述该实现方式的几种示例，其中，场景2是指：以上述图1f和图1g所示意的情形为例，终端设备以第一用户身份使用射频Tx1通路和射频Tx2通路与第一网络设备进行通信，假定第一信息包括第一指示信息(指示射频Tx2通路切出)和第二指示信息(指示第一时长为3个时隙)。
基于上述场景2，在该实现方式的一个示例中，终端设备以第一用户身份向第一网络设备发送第一信息，相应地，第一网络设备接收到第一信息后，若拒绝射频Tx2通路切出，则可以不向终端设备发送相应的相应。进而，终端设备若在设定时间段内未接收到第一网络设备的响应，则获知第一网络设备拒绝射频Tx2通路切出，此时，终端设备不再将射频Tx2通路切出。在该示例中，未执行步骤203至步骤206。
基于上述场景2，在该实现方式的又一个示例中，终端设备以第一用户身份向第一网络设备发送第一信息，相应地，第一网络设备接收到第一信息后，若拒绝射频Tx1通路切出，则可以向终端设备发送第三指示信息，第三指示信息指示的第二资源包括射频Tx1通路和射频Tx2通路。进而，终端设备接收到第一网络设备发送的第三指示信息后，获知第一网络设备拒绝射频Tx2通路切出，此时，终端设备不再将射频Tx2通路切出。在该示例中，执行了步骤203和步骤204；未执行步骤205和步骤206。
基于上述场景2，在该实现方式的又一个示例中，终端设备以第一用户身份向第一网络设备发送第一信息，相应地，第一网络设备接收到第一信息后，若同意射频Tx2通路切出，则可以向终端设备发送第三指示信息和第四指示信息(指示第二时长为2个时隙)，第三指示信息指示的第二资源包括射频Tx1通路。进而，终端设备接收到第一网络设备发送的第三指示信息和第四指示信息后，可以将射频Tx2通路切出。终端设备若确定射频Tx2通路切出的时长达到第二时长(即2个时隙)，则将射频Tx2通路切回；进一步地，终端设备可以以第一用户身份向第一网络设备发送第五指示信息，或者，也可以不以第一用户身份向第一网络设备发送第五指示信息。在该示例中，执行了步骤203和步骤204；可以执行或者也可以不执行步骤205和步骤206。
需要说明的是：(1)在上述所描述的各种可能的示例中，终端设备将第一资源由第一状态切换为第二状态(或者说将第一资源切出)后，终端设备可以以第二用户身份使用第一资源与第二网络设备进行通信，比如可以是仅从第二网络设备接收数据(如监听寻呼消息或进行小区策略)，或者也可以向第二网络设备发送数据。终端设备以第二用户身份使用第一资源与第二网络设备进行通信，可以是可预期时间段的通信(如监听寻呼消息或进 行小区策略)，或者，也可以是不可预期时间段的通信(比如打电话)。
(2)上述仅是从终端设备与第一网络设备通信的角度，对第一网络设备的行为进行了相应的描述。在其它可能的实施例中，比如，第一网络设备根据第一信息获知终端设备的射频资源和/或基带处理资源在不同SIM卡之间的切换后，可以及时调整资源分配、调制与编码策略(modulation and coding scheme，MCS)选择等，以提高系统的传输效率；本申请实施例中，对第一网络设备根据第一信息所执行的用于提高传输效率的行为不做限定。又比如，第一网络设备接收到第一信息后，若第一信息包括第二指示信息，则可以根据第二指示信息执行相应的操作，如若第二指示信息所指示的时长较短，则可以在第二指示信息所指示的时长内不再进行上行或下行调度；若第二指示信息所指示的时长较长，则可以将终端设备在SIM卡1所属的网络中的状态从RRC_conntected转移到RRC_inactive或RRC_idle。又比如，第一网络设备接收到第一信息后，还可以标注终端设备的工作状态，不继续(或暂停)进行终端设备的相关统计信息。
下面结合实施例二描述本申请实施例提供的通信方法的一种可能的实现流程。
实施例二
在实施例二中，终端设备支持SIM卡1(对应于第一用户身份)和SIM卡2(对应于第二用户身份)，且终端设备中仅配置有一个射频Rx1通路，比如上述图1b和图1c中所示意的情形。终端设备可以以第一用户身份和第二用户身份工作在不同的频率上，射频Rx1通路可以接收以一定频率为中心并且在接收带宽内的数据。
图4为本申请实施例二提供的通信方法所对应的流程示意图。如图4所示，包括：
步骤401，终端设备在SIM卡1所属的系统(或者说SIM卡1所属的网络，即第一网络)与第一网络设备进行通信，此时终端设备处于RRC_connected。
步骤402，终端设备以第一用户身份向第一网络设备发送第一信息，比如第一信息中可以包括第一指示信息(比如表1中的001)，用于指示射频Rx1通路切出。
步骤403，第一网络设备接收到第一信息后，向终端设备发送第四指示信息，第四指示信息指示第二时长为2个时隙。
示例性地，第一网络设备还可以执行其它可能的操作，比如将终端设备在SIM卡1所属的网络中的状态从RRC_conntected转移到RRC_inactive或RRC_idle，又比如暂停进行终端设备的相关统计信息。
步骤404，终端设备将射频Rx1通路从关联SIM卡1切换为关联SIM卡2。
也就是说，终端设备可以以第二用户身份通过射频Rx1通路接收第二网络设备发送的数据，而无法再以第一用户身份通过射频Rx1通路接收第一网络设备发送的数据。
步骤405，终端设备确定射频Rx1通路切出的时长达到2个时隙后，将射频Rx1通路切回到关联SIM卡1，也就是说，终端设备可以以第一用户身份通过射频Rx1通路接收第一网络设备发送的数据，而无法再以第二用户身份通过射频Rx1通路接收第二网络设备发送的数据。
步骤406，第一网络设备恢复与终端设备之间的通信。示例性地，如果上述步骤403中，第一网络设备将终端设备在SIM卡1所属的网络中的状态从RRC_conntected转移到RRC_inactive或RRC_idle，则需要将终端设备在SIM卡1所属的网络中的状态转移到RRC_conntected后，再进行数据的收发。如果上述步骤403中，第一网络设备暂停进行终 端设备的相关统计信息，则此时可以继续进行终端设备的相关统计信息。
参见图5为本申请实施例二提供的射频Rx1通路的切换流程示意图，如图5所示：
在过程1中，终端设备以在SIM卡1所属的网络中与第一网络设备进行通信，比如接收第一网络设备发送的下行数据。示例性地，终端设备可以向第一网络设备发送第一信息，比如第一信息中可以包括第一指示信息(比如表1中的001)，用于指示射频Rx1通路切出，相应地，第一网络设备可以向终端设备发送第四指示信息，比如图5中标注为①的实线代表第一网络设备向终端设备发送第四指示信息。终端设备接收到第四指示信息后，可以将射频Rx1通路从关联SIM卡1切换为关联SIM卡2。图5中的过程1可以对应于图4中的步骤401至步骤403。
在过程2中，终端设备可以在SIM卡2所属的网络中与第二网络设备进行通信，比如接收第二网络设备发送的下行数据，比如图5中标注为②的实线代表终端设备接收第二网络设备发送的下行数据、图5中标注为③的虚线代表终端设备无法接收第一网络设备发送的下行数据。图5中的过程2可以对应于图4中的步骤404。
在过程3中，终端设备确定射频Rx1通路切出的时长达到2个时隙后，将射频Rx1通路切回到关联SIM卡1，进而终端设备在SIM卡1所属的网络中可以与第一网络设备进行通信，比如接收第一网络设备发送的下行数据，比如图5中标注为④的实线代表终端设备接收第一网络设备发送的下行数据。图5中的过程3可以对应于图4中的步骤405至步骤406。
在过程3之后，终端设备还可以再次将射频Rx1通路从SIM卡1切出到SIM卡2(对应于过程4)，以及再将射频Rx1通路切回到SIM卡1(对应于过程5)，具体不再赘述。

图6为本申请实施例三提供的通信方法所对应的流程示意图，如图6所示，包括：
步骤601，终端设备在SIM卡1所属的网络与第一网络设备进行通信，此时终端设备处于RRC_connected。终端设备可以使用射频Tx1通路和射频Tx2通路进行数据的发送。
步骤602，终端设备以第一用户身份向第一网络设备发送第一信息，比如第一信息中可以包括第一指示信息(比如表3中的01)，用于指示射频Tx2通路切出，即射频发射通路从两个(即射频Tx1通路和射频Tx2通路)变为1个(即射频Tx1通路)。
步骤603，第一网络设备接收到第一信息后，向终端设备发送第四指示信息，第四指示信息指示第二时长为2个时隙。
步骤604，终端设备将射频Tx2通路从关联SIM卡1切换为关联SIM卡2，也就是说，终端设备可以以第二用户身份通过射频Tx2通路向第二网络设备发送数据，而无法再以第一用户身份通过射频Tx2通路向第一网络设备发送数据。
步骤605，终端设备确定射频Tx2通路切出的时长达到2个时隙后，将射频Tx2通路 切回到关联SIM卡1，也就是说，终端设备可以以第一用户身份通过射频Tx1和Tx2通路向第一网络设备发送数据，而无法再以第二用户身份通过射频Tx2通路向第二网络设备发送数据。
步骤606，第一网络设备恢复与终端设备之间的通信。

在过程2中，终端设备可以在SIM卡2所属的网络中使用射频Tx2通路与第二网络设备进行通信，比如使用射频Tx2通路向第二网络设备发送上行数据，以及终端设备可以在SIM卡1所属的网络中使用射频Tx1通路与第一网络设备进行通信，比如使用射频Tx1通路向第一网络设备发送上行数据，比如图7中标注为②的实线代表终端设备使用射频Tx2通路向第二网络设备发送上行数据，标注为③的虚线代表终端设备使用射频Tx1通路向第一网络设备发送上行数据。图7中的过程2可以对应于图6中的步骤604。
在过程3中，终端设备确定射频Rx2通路切出的时长达到2个时隙后，将射频Rx2通路切回到关联SIM卡1，进而终端设备在SIM卡1所属的网络中可以使用射频Tx1通路和射频Tx2通路与第一网络设备进行通信，比如向第一网络设备发送上行数据，比如图7中标注为④的实线代表终端设备使用射频Tx1通路和射频Tx2通路向第一网络设备发送上行数据。图7中的过程3可以对应于图6中的步骤605至步骤606。
针对于上述内容，需要说明的是：(1)图2、图4和图6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、图4和图6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。
(2)本申请实施例中所描述的资源切换也可以理解为能力协调，比如，终端设备的射频资源和/或基带处理资源在不同SIM卡之间切换，可以是指，终端设备使用射频资源和/或基带处理资源的能力在不同SIM卡之间自适应协调。
(3)终端设备以SIM卡1对应的用户身份注册在第一网络后，后续可以是由第一网络中的一个小区(比如归属于第一网络设备的一个小区)为终端设备提供服务，或者也可以是由第一网络中的多个小区为终端设备提供服务；其中，多个小区可以为归属于第一网络中的同一网络设备(比如第一网络设备)的小区，此种情形可以理解为载波聚合(carrier aggregation，CA)，或者，多个小区也可以为归属于第一网络中的不同网络设备的小区，此种情形可以理解为双连接(dual connectivity，DC)。类似地，终端设备以SIM卡2对应的用户身份注册在第二网络后，后续可以是由第二网络中的一个小区为终端设备提供服务，或者也可以是由第二网络中的多个小区为终端设备提供服务。
(4)上述实施例一、实施例二和实施例三中，终端设备和第一网络设备通信时(比 如终端设备发送第一指示信息或第五指示信息，第一网络设备发送第三指示信息或第四指示信息)可以在第一网络为该终端设备配置的一个或多个小区上进行；终端设备和第二网络设备通信时可以在第二网络为该终端设备配置的一个或多个小区上进行，或者在终端设备在第二网络中选择的驻留小区上进行(比如终端设备在第二网络中发起随机接入过程，可以是在驻留小区上进行)，具体不做限定。
