Description

一种双卡通信的方法和终端设备
本申请要求于2022年5月30日提交国家知识产权局、申请号为202210603383.6、申请名称为“一种双卡通信的方法和终端设备”的中国专利申请的优先权，要求于2022年6月28日提交国家知识产权局、申请号为202210742421.6、申请名称为“一种双卡通信的方法和终端设备”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
本申请涉及通信领域，更具体地，涉及通信领域中一种双卡通信的方法和终端设备。
背景技术
随着通信的发展，目前的终端设备(例如，手机)大部分都支持双卡双待(dual sim dual standby，DSDS)或双卡双通(dual sin dual active，DSDA)模式。在DSDA模式下，终端设备支持双卡的业务并发，即双卡可实现同时发送或接收，一个卡执行通话业务时，另一个卡可以收到来电，也可以执行数据业务(即上网)。在DSDS模式下，终端设备不支持双卡业务并发，一个卡执行通话业务时，另一个卡无法进行数据业务，以及，一个卡执行数据业务时，另一个卡虽然可以接收来电，但来电会打断数据业务，对于主卡来讲，副卡的通话业务使得主卡无法进行数据业务，而且，副卡由于搜网、测量、跟踪区更新(tracking area update,TAU)、短信、彩信、周期性注册等行为会抢占天线，影响主卡的上网体验。可以看出，相比于DSDS模式，DSDA模式的用户体验更高。
当终端设备的双卡均处于连接态时，双卡间形成DSDA模式，双卡均可进行上行传输和下行传输。但是，当双卡中的至少一个卡进行小区切换后，若双卡最终驻留的小区的频段无法形成DSDA模式而只能形成DSDS模式，那么，双卡中任一个卡的上行传输必然会受到影响，导致该任一个卡的业务中断，这样的小区切换是失败的，非常影响用户体验。
发明内容
本申请实施例提供一种双卡通信的方法和终端设备，在双卡均处于连接态的情况下进行小区切换时，尽可能使得完成小区切换后双卡最终驻留的小区的频段之间形成DSDA模式以继续保持双卡的连接态，使得每个卡的业务的正常进行，从而，提高用户体验。
第一方面，提供了一种双卡通信的方法，应用于终端设备中，所述终端设备的第一卡和第二卡均处于连接态，所述方法包括：确定所述第一卡的邻区频段和所述第二卡的邻区频段之间是否能够形成所述终端设备支持的双卡双通DSDA模式；对能够形 成DSDA模式的所述第一卡和所述第二卡中每个卡的初始候选频段进行测量；确定所述每个卡的初始候选频段中满足预设条件的第一候选频段，所述预设条件包括：所述每个卡的邻区的质量满足用于小区切换的事件，一个邻区对应一个频段；根据基于所述第一卡的第一候选频段和所述第二卡的第一候选频段之间形成的DSDA模式的至少一个DSDA组合，确定目标DSDA组合，所述目标DSDA组合包括所述第一卡的第一候选频段中的目标频段和所述第二卡的第一候选频段中的目标频段；上报测量报告，所述测量报告用于指示所述第一卡的目标频段的质量和所述第二卡的目标频段的质量。
本申请实施例提供的双卡通信的方法，在第一卡和第二卡均处于连接态的情况下，第一卡和第二卡之间形成DSDA模式，当需要进行小区切换时，首先确定第一卡的邻区频段和第二卡的邻区频段之间是否能够形成终端设备支持的DSDA模式，在能够形成DSDA模式的情况下继续执行后续步骤，以优先保证第一卡和第二卡切换小区后驻留的小区的频段之间依然能够形成DSDA模式，随后，对能够形成DSDA模式的每个卡的初始候选频段进行测量、从每个卡的初始候选频段中确定满足预设条件(即，质量要求)的第一候选频段以及从第一卡和第二卡的第一候选频段中确定出包括每个卡的目标频段的目标DSDA组合，向网络设备上报测量报告，以便于网络设备指示终端设备将第一卡和第二卡分别切换至对应的目标频段上，进一步保证了切换小区后第一卡和第二卡驻留的小区的频段的质量。综上，上述方法不仅能够使得切换小区后第一卡和第二卡驻留的频段继续形成DSDA模式以保持连接态，不影响每个卡的业务的正常进行，而且，切换小区后第一卡和第二卡驻留的频段的质量优于第一卡和第二卡之前驻留的频段的质量，提高了信号质量，总体上均有效地提高了用户体验。
可选地，所述至少一个DSDA组合包括多个DSDA组合；以及，所述根据基于所述第一卡的第一候选频段和所述第二卡的第一候选频段之间形成的DSDA模式的至少一个DSDA组合，确定目标DSDA组合，包括：
将所述至少一个DSDA组合中优先级最高的DSDA组合确定为所述目标DSDA组合。
本申请实施例提供的双卡通信的方法，终端设备通过将优先级最高的DSDA组合作为目标DSDA组合，能够使得进行小区切换后第一卡和第二卡驻留的频段之间形成的DSDA模式是终端设备设定的最优模式，提高了双卡模式的性能，用户体验好。
可选地，所述目标DSDA组合是所述多个DSDA组合中双卡模式的能力最好的组合。
本申请实施例提供的双卡通信的方法，终端设备通过将多个DSDA组合中双卡模式的能力最好的组合确定为目标DSDA组合，能够使得进行小区切换后第一卡和第二卡驻留的频段之间形成的DSDA模式是性能最好的双卡模式，用户的体验最好。
可选地，所述方法还包括：
在所述第一卡的邻区频段和所述第二卡的邻区频段无法形成所述终端设备支持的DSDA模式的情况下，对所述每个卡的邻区频段不进行测量。
本申请实施例提供的双卡通信的方法，在所述第一卡的邻区频段和所述第二卡的邻区频段无法形成终端设备支持的DSDA模式的情况下，对每个卡的邻区频段不进行测量，这样，第一卡和第二卡能够继续驻留在当前的小区而不进行小区切换，以继续 保持双卡的DSDA模式，从而能够保证第一卡和第二卡继续处于连接态，一定程度上不影响业务的正常进行，以尽可能保证良好的用户体验。此外，终端设备对每个卡的邻区频段不进行测量，还能避免由于无效的测量造成的功耗浪费，节省了功耗。
可选地，在所述确定所述第一卡的邻区频段和所述第二卡的邻区频段之间是否能够形成所述终端设备支持的双卡双通DSDA模式之前，所述方法还包括：
确定所述第一卡当前执行的业务的优先级与所述第二卡当前执行的业务的优先级相同。
本申请实施例提供的双卡通信的方法，若第一卡和第二卡当前执行的业务的优先级不同，例如，一个卡执行通话业务，另一个卡执行数据业务，通话业务的优先级高于数据业务的优先级，若优先考虑第一卡和第二卡切换小区后驻留的频段是否能够形成DSDA模式再考虑质量要求，对于执行通话业务的卡而言，最终确定的目标频段的质量可能并不是所有邻区频段中质量靠前的，所以，执行通话业务的卡的性能可能达不到最优，一定程度上会影响用户体验。因此，在第一卡当前执行的业务的优先级与第二卡当前执行的业务的优先级相同的情况下，先确定第一卡和第二卡切换小区后驻留的频段是否能够形成DSDA模式再考虑质量要求，能够避免出现由于某个卡当前执行的业务的优先级高但切换小区后该某个卡驻留的频段的质量并不是很好的情况，从而在一定程度上影响用户体验。
可选地，所述第一卡和所述第二卡当前执行的业务均为数据业务。
第二方面，提供了一种双卡通信的方法，应用于终端设备中，所述终端设备的双卡均处于连接态，所述方法包括：在所述双卡当前执行的业务的优先级不同的情况下，确定所述双卡中第一卡的邻区频段中满足第一预设条件的第一目标频段，所述第一卡当前执行的业务的优先级高于所述双卡中第二卡当前执行的业务的优先级，所述第一预设条件包括：所述第一卡的邻区的质量满足用于小区切换的事件，一个邻区对应一个频段；确定所述第二卡的邻区频段中能够与所述第一目标频段形成所述终端设备支持的双卡双通DSDA模式的初始候选频段；确定所述第二卡的初始候选频段中满足第二预设条件的第一候选频段，所述第二预设条件包括：所述第二卡的邻区的质量满足用于小区切换的事件，一个邻区对应一个频段；上报测量报告，所述测量报告用于指示所述第一目标频段的质量和基于所述第一候选频段确定的第二目标频段的质量。
本申请实施例提供的双卡通信的方法，在双卡均处于连接态的情况下，当双卡当前执行的业务的优先级不同时，终端设备先从业务优先级高的第一卡的邻区频段中确定满足第一预设条件(质量要求)的第一目标频段，以优先保证业务优先级高的第一卡的质量，然后再从业务优先级低的第二卡的邻区频段中确定能够与第一目标频段形成DSDA模式的初始候选频段以及从初始候选频段中确定满足第二预设条件(质量要求)的第一候选频段，从第一候选频段中确定第二目标频段，向网络设备上报测量报告，以便于网络设备指示终端设备将第一卡和第二卡分别切换至对应的目标频段上，进一步保证了切换小区后双卡驻留的频段也能够形成DSDA模式以继续保持连接态，总体提高了用户体验。综上，上述方法不仅优先保证了业务优先级高的第一卡的质量，而且，能够使得切换小区后双卡驻留的频段继续形成DSDA模式以保持连接态，不影响每个卡的业务的正常进行，此外，切换小区后双卡驻留的频段的质量均优于双卡之 前驻留的频段的质量，提高了信号质量，总体上更好地提高了用户体验。
可选地，所述第一候选频段包括多个频段；以及，在所述上报测量报告之前，所述方法还包括：
将所述第一候选频段中优先级最高的频段确定为所述第二目标频段。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案适用于能够与网络设备通信且支持双卡通信的终端设备，每个卡均可支持电话业务和数据业务(即，上网业务)，例如，终端设备可以是手机、智能手表、智能手环或平板电脑等，本申请实施例对终端设备的具体类型不做任何限制。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(global system for mobile communications，GSM)系统，通用分组无线服务(general packet radio service，GPRS)系统，码分多址接入(code division multiple access，CDMA)系统，宽带码分多址(wideband code division multiple access，WCDMA)系统，时分码分多址(time-division code division multiple access，TD-SCDMA)，长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、第五代新无线(5th generation new radio，5G NR)或未来的第六代(6th generation，6G)系统等，其中，5G NR简称NR。
本申请实施例适用于包括多个基站和至少一个终端设备的移动通信系统中，其中，多个基站中至少包括能够支持5G网络的基站和能够支持4G网络的基站。示例性地，如图1所示，移动通信系统包括基站110、基站120和终端设备130，基站110和基站120中的一个能够支持4G网络，另一个能够支持5G网络，终端设备130可与基站110和基站120中的至少一个连接。为了便于描述，将支持4G网络的基站简称为4G基站，将支持5G网络的基站简称为5G基站。
若终端设备130与基站110和基站120中的一个连接时，双卡均驻留在同一网络(4G网络或5G网络)。若终端设备130均与基站110和基站120连接，那么，可能有以下3种情况。情况1、终端设备支持4G网络和5G网络的双连接，以及，两个卡中的每个卡均处于双连接状态，即，每个卡同时连接4G网络和5G网络。情况2、一个卡驻留在4G网络，另一个卡驻留在5G网络。情况3、终端设备支持LTE网络和5G网络的双连接，一个卡驻留在4G网络或5G网络，另一个卡同时连接4G网络和5G网络。
需要说明的是，由于双卡并不一定支持同一个运营商，所以，当双卡同时驻留在4G网络或5G网络时，双卡驻留的4G基站或5G基站可能并不相同，因此，移动通信系统中可能包括多个基站110和/或多个基站120。当某个基站(例如，基站110或基站120)为共享网络的基站时，即使双卡不支持同一个运营商，系统依然允许双卡驻留在该基站支持的网络中，其中，共享网络为不同运营商共享的网络。
假设，双卡支持不同的运营商，卡1支持运营商1，卡2支持运营商2，移动通信系 统中包括一个基站110和两个基站120。
在一示例中，若基站110为共享4G网络的4G基站，基站120为非共享5G网络的5G基站，一个基站120支持运营商1，另一个基站120支持运营商2。若双卡同时驻留在4G网络，则双卡均驻留在同一个基站110(即，4G基站)；若双卡同时驻留在5G网络，则双卡驻留在不同的基站120(即，5G基站)上，卡1驻留在运营商1对应的基站120上，卡2驻留在运营商2对应的基站120上。
在另一示例中，若基站110为共享5G网络的5G基站，基站120为非共享4G网络的4G基站，一个基站120支持运营商1，另一个基站120支持运营商2。若双卡同时驻留在5G网络，则双卡均驻留在同一个基站110(即，5G基站)；若双卡同时驻留在4G网络，则双卡驻留在不同的基站120(即，4G基站)上，卡1驻留在运营商1对应的基站120上，卡2驻留在运营商2对应的基站120上。
再假设，双卡支持不同的运营商，卡1支持运营商1，卡2支持运营商2，移动通信系统中包括两个基站110和两个基站120，基站110为非共享4G网络的4G基站，一个基站110支持运营商1，另一个基站110支持运营商2，基站120为非共享5G网络的5G基站，一个基站120支持运营商1，另一个基站120支持运营商2。若双卡同时驻留在4G网络，则双卡驻留在不同的基站110(即，4G基站)上，卡1驻留在运营商1对应的基站110上，卡2驻留在运营商2对应的基站110上；若双卡同时驻留在5G网络，则双卡驻留在不同的基站120(即，5G基站)上，卡1驻留在运营商1对应的基站120上，卡2驻留在运营商2对应的基站120上。
应理解，图1示出的移动通信系统仅为示意性说明，不应对本申请实施例构成限定。例如，移动通信系统中还可以包括核心网设备，以及，更多的基站和终端设备等。

上文对本申请实施例的通信系统和终端设备做了介绍，以下，对本申请实施例涉及的相关术语做说明。
双卡双待(dual sim dual standby，DSDS)
终端设备支持的一种双卡模式，也可以理解为终端设备的双卡能力，双卡的接收天线分时复用。在DSDS模式下，终端设备不支持双卡业务并发，具体表现为：(1)一个卡执行通话业务时，另一个卡无法进行数据业务(即，上网)；(2)一个卡执行数据业务时，另一个卡虽然可以接收来电，但来电会打断数据业务。
对于双卡中的主卡来讲，副卡的通话业务会使得主卡无法进行数据业务，而且，副卡由于搜网、测量、跟踪区更新(tracking area update,TAU)、短信、彩信、周期性注册等行为会抢占天线，使得主卡的上网体验较差。
双接收双卡双待(dual receiver-dual simdual dtandby，DR-DSDS)
终端设备支持的另一种双卡模式，也可以理解为终端设备的另一种双卡能力，双卡的接收天线可以分集复用，即一个卡用主集，另一个卡用分集，双卡可以同时接收，但无法同时发送。在DR-DSDS模式下，(1)一个卡执行通话业务时，另一个卡有信号，但是无法响应寻呼，以及，无法进行TAU；(2)一个卡执行数据业务时，另一个卡进行上行传输时，需抢占射频(radio frequency，RF)天线，从而影响执行数据业务的卡的体验。
双卡双通(dual sin dual active，DSDA)
终端设备支持的另一种双卡模式，也可以理解为终端设备的另一种双卡能力。在DSDA模式下，终端设备支持双卡的业务并发，即两个卡可实现同时发送或接收，一个卡执行通话业务时，另一个卡可以收到来电，也可以执行数据业务(即上网)。
DSDA模式进一步可包括两种模式，DSDA发射共享模式和DSDA发射独享模式。在DSDA发射共享模式下，两个卡在上行传输时共用天线且分时发送，在下行传输时两个卡分别使用不同的天线，不过，由于两个卡的上行传输共用天线，用户上网的性能体验有损失。在DSDA发射独享模式下，两个卡在上行传输时分别使用不同的天线，在下行传输时也分别使用不同的天线，上行传输和下行传输均完全独立，用户上网的性能体验基本无损失，比在DSDA发射独享模式下的性能体验好。
非独立组网(non-standalone，NSA)和独立组网(standalone，SA)随着5G的发展，5G包括NSA和SA两种组网方式。
NSA指的是利用现有的4G核心网等设施，进行5G网络的部署，是4G和5G融合的组网方式。基于NSA架构的5G载波仅承载用户数据，控制信令仍通过4G网络传输。在NSA中，5G无法单独工作，仅仅是作为4G的补充，分担4G的流量。
SA指的是新建5G网络，包括新基站、回程链路以及核心网。SA引入了全新网元与接口的同时，还将大规模采用网络虚拟化、软件定义网络等新技术，并与5GNR结合，同时其协议开发、网络规划部署及互通互操作所面临的技术挑战将超越3G和4G系统。目前的SA有两种组网方式，一种组网方式是采用5G基站连接5G核心网，这是5G网络架构的终极形态，可以支持5G的所有应用，但花费很大；另一种组网方式是将现有的4G基站升级，变成增强型4G基站，将增强型4G基站接入5G核心网，花费较少。
在本申请实施例中，4G可作为LTE的替换描述，5G可作为NR的替换描述，若无特殊说明，两者可替换描述。
如前所述，相比于DSDS模式，DSDA模式的用户体验更好。但是，目前市场上终端设备中主流的芯片对DSDA模式的支持是不完善的，很多场景下终端设备处于DSDS模式而非处于DSDA模式，由此降低了用户体验。可以看出，通过使得终端设备尽可能处于DSDA模式，可以提高用户体验。
终端设备支持的双卡模式与各个卡所处的网络和频段有关，目前，NR SA网络的部分频段与LTE网络的部分频段支持DSDA模式，以及，NR SA网络的部分频段与NR SA网络的部分频段可支持DSDA模式，其中，NR SA表示5G网络，具体表示组网方式为SA的5G网络，简称NR SA，LTE表示4G网络。
DSDA模式包括一个或多个DSDA组合，DSDA组合包括双卡的网络类型和频段。为了便于描述，可采用“网络1频段号+网络2频段号”的方式表示DSDA组合。此外，可以将LTE网络的频段简称为LTE频段，将NR网络的频段简称为NR频段，LTE频段可以采用LTE频段号表示，LTE频段号可采用Bx表示，x为大于0的整数，例如，B1，同理，NR频段可采用NR频段号表示，NR频段号可采用nx表示，n为大于0的整数，例如，n78。
例如，DSDA模式的一个DSDA组合为NR SA n41+LTE B1，表示的是，一个卡驻留在NR SA网络中n41指示的频段，n41为NR频段号，表示一个NR频段，另一个卡驻留在LTE网络中B1指示的频段，B1表示LTE频段号，表示一个LTE频段。
从上述可以看出，只要双卡当前驻留的网络的网络类型和频段满足DSDA模式中任一个DSDA组合包括的网络类型和频段，双卡间就能够形成DSDA模式，终端设备就能够处于DSDA模式。
在小区切换(handover)的场景中，当双卡中至少一个卡驻留的服务小区的质量变差时，终端设备会基于网络设备的指示对至少一个卡中每个卡驻留的服务小区的邻区进行测量以切换至质量好的邻区。
当终端设备的双卡均处于连接态时，双卡间形成DSDA模式，双卡均可进行上行传输和下行传输，但是，在完成小区切换后，若双卡最终驻留的小区的频段无法形成DSDA模式而只能形成DSDS模式，那么，双卡中任一个卡的上行传输必然会受到影响，导致该任一个卡的业务中断，这样的小区切换是失败的，非常影响用户体验。
基于此，本申请实施例提出，在双卡均处于连接态的场景下，双卡间形成DSDA模式，对小区切换的流程做改进，在确定完成小区切换后双卡最终驻留的小区的频段有机会形成DSDA模式的情况下，对至少一个卡的邻区进行测量以进行小区切换，以使得双卡最终驻留的小区的频段间能够形成DSDA模式，这样，双卡依然均能够处于连接态，任一个卡的上行传输都不受影响，保持业务的正常进行，从而，能够提高用户体验。
需要说明的是，小区切换过程中进行的小区(服务小区或邻区)测量，表示的是对小区的频点进行测量，一个小区对应一个频点。由于一个频点对应一个频段，所以，小区测量也可以表示为对小区的频段进行测量。其中，频点表示的是中心频点，根据频点可以得到频段。
还需要说明的是，本申请实施例默认双卡驻留的网络，不需要调整某个卡驻留的网络，仅对某个卡当前驻留网络的频段进行调整。
以下，结合附图，对不同场景下的双卡通信的方法做详细说明。
图3是本申请实施例提供的双卡通信的方法300的示意性流程图。该方法300可由支 持双卡通信的终端设备执行，也可由终端设备中的芯片执行，本申请实施例不做任何限定。为了便于描述，以终端设备为例对方法300做详细说明。
方法300所示的实施例是双卡进行小区切换的场景，通过相关设计尽可能使得切换小区后双卡驻留的频段间依然形成DSDA模式以继续保持连接态，以提高用户体验。若切换小区后双卡驻留的频段间无法形成DSDA模式，则不进行小区切换，以继续保持当前的DSDA模式，使得双卡均处于连接态，不影响每个卡的业务的正常进行。
在方法300中，卡1为主卡和副卡中的其中一个，卡2为主卡和副卡中的另一个，此处不做任何限定。
在S310中，终端设备确定卡1和卡2均处于连接态。
当卡1和卡2均处于连接态的时候，意味着卡1和卡2均可独立进行上行传输和下行传输，而只有卡1和卡2之间形成DSDA模式的情况下才会使得卡1和卡2均处于连接态。所以，当卡1和卡2均处于连接态时，卡1和卡2间必然已形成DSDA模式。因此，终端设备确定卡1和卡2均处于连接态时也相当于确定了卡1和卡2之间形成DSDA模式。
在S320中，终端设备接收网络设备发送的卡1和卡2中每个卡的测量控制信息。
测量控制信息用于指示每个卡的邻区频点，邻区频点表示每个卡当前驻留的小区(即，服务小区)的邻区的频点，邻区频点包括至少一个频点，至少一个频点与至少一个邻区一一对应，一个频点对应一个邻区。
为了便于描述，将卡1的测量控制信息记为测量控制信息1，将卡2的测量控制信息记为测量控制信息2。测量控制信息1用于指示卡1的邻区频点，测量控制信息2用于指示卡2的邻区频点。
应理解，测量控制信息1和测量控制信息2可以是网络设备同时发送的，也可以是网络设备先后在不同时段发送的，本申请实施例不做任何限定。
此外，对于每个卡的测量控制信息，网络设备可以是周期性发送的，也可以基于事件触发发送的，本申请实施例不做任何限定。
在网络设备基于事件触发发送测量控制信息的实施例中，用于触发网络设备发送测量控制信息的事件可以是每个卡当前驻留的小区的质量变差的事件，示例性地，上述事件可以包括A2事件，A2事件表示服务小区的信号质量低于一定门限的事件。
上述网络设备包括一个或多个基站，测量控制信息1和测量控制信息2可以是同一个基站发送的也可以是不同基站发送的，主要视卡1和卡2驻留的网络是否相同以及是否支持相同的运营商的情况而定。
假设，卡1和卡2支持同一个运营商，卡1和卡2驻留在相同的网络，这种情况下，网络设备可以仅包括一个基站，测量控制信息1和测量控制信息2由同一个基站发送。
再假设，卡1和卡2支持同一个运营商，卡1和卡2驻留在不同的网络，这种情况下，网络设备可以包括两个基站，一个基站支持一个网络，不同的基站为驻留在对应网络的卡发送测量控制信息。例如，卡1驻留在5G网络，卡2驻留在4G网络，那么，5G基站为卡1发送测量控制信息1，4G基站为卡2发送测量控制信息2。
再假设，卡1和卡2支持不同的运营商，卡1和卡2驻留在相同的网络，这种情况下，网络设备可以包括一个或两个基站。当网络设备包括一个基站时，该基站为不同运行商可共享同一个网络(简称共享网络)的基站，该基站可以在双卡不支持同一个运营商时允许 双卡驻留在该基站支持的网络中，这种情况下，测量控制信息1和测量控制信息2由同一个基站发送。当网络设备包括两个基站时，一个基站对应一个运营商，测量控制信息1和测量控制信息2分别由支持对应的运营商的基站发送。
在S330中，终端设备确定卡1的邻区频段和卡2的邻区频段之间是否能够形成终端设备支持的DSDA模式。
邻区频点包括至少一个频点，邻区频段包括该至少一个频点一一对应的至少一个频段。
在该步骤中，终端设备根据从测量控制信息1中得到的卡1的邻区频点确定对应的邻区频段，根据从测量控制信息2中得到的卡2的邻区频点确定对应的邻区频段，进而根据终端设备的DSDA模式信息，确定卡1的邻区频段和卡2的邻区频段之间是否能够形成终端设备支持的DSDA模式。
若卡1的邻区频段和卡2的邻区频段之间能够形成终端设备支持的DSDA模式，意味着卡1和卡2进行小区切换后有机会继续形成DSDA模式以继续保持双卡的连接态，则继续执行S341。
若卡1的邻区频段和卡2的邻区频段之间无法形成终端设备支持的DSDA模式，意味着卡1和卡2进行小区切换后无法形成DSDA模式从而无法保证双卡的连接态，使得小区切换失败，所以，对卡1和卡2的邻区频段不进行测量或者即使测量了也不上报测量结果，具体参考下文关于步骤S342的相关描述，不再赘述。
DSDA模式信息用于指示终端设备支持的能够形成DSDA模式的所有DSDA组合，每个DSDA组合包括双卡的网络类型和频段。实现中，可以在终端设备中预配置DSDA模式信息。
应理解，同一个终端设备支持的DSDA组合是固定的，不同终端设备支持的DSDA组合可以相同也可以不同，具体可以根据终端设备的型号或硬件信息确定。为了便于描述，以表1的形式列出某个终端设备支持的双卡模式的组合，在表1中，DSDA模式有3个DSDA组合，DSDA发射共享模式中由NRSAn1+NRSA n1形成的DSDA组合，DSDA发射独享模式中由NRSA n1+NRSA n78形成的DSDA组合，DSDA发射独享模式中由NRSAn1+LTE B41形成的DSDA组合。其中，表1中的3个DSDA组合可以是DSDA模式信息指示的终端设备支持的所有DSDA组合。
表1

以下，举例说明终端设备确定卡1的邻区频段和卡2的邻区频段是否能够形成终端设备支持的DSDA模式的过程。
假设，卡1驻留在网络1，卡1的邻区频段包括网络1的3个频段，分别是：频段11、频段12、频段14，卡2驻留在网络2，卡2的邻区频段包括网络2的2个频段，分别是频段21和频段22，终端设备的DSDA模式信息指示的终端设备支持的DSDA模式的所有DSDA组合包括3个DSDA组合，分别是：由“网络1频段11+网络2频段21”形成的DSDA组合1，以及，由“网络1频段12+网络2频段22”形成的DSDA组合2，由“网络1频段14+网络2频段23”形成的DSDA组合3。可以看出，卡1的邻区频段中的频段11和卡2的邻区频段中的频段21可形成DSDA模式的DSDA组合1，卡1的邻区频段中的频段12和卡2的邻区频段中的频段22可形成DSDA模式的DSDA组合2，所以，卡1的邻区频段和卡2的邻区频段能够形成DSDA模式，且可形成DSDA模式的2个DSDA组合。
在S342中，在卡1的邻区频段和卡2的邻区频段之间无法形成DSDA模式的情况下，终端设备对每个卡的邻区频段不进行测量，或者，对每个卡的邻区频段测量后不上报测量结果。
由于卡1的邻区频段和卡2的邻区频段之间无法形成DSDA模式，意味着卡1和卡2进行小区切换后是无法形成DSDA模式的，从而无法保证两个卡依然处于连接态，这样的小区切换是失败的。因此，在该步骤中，示例性地，终端设备对双卡的邻区频段可执行以下两种方案。
在一种实现方式中，终端设备对卡1的邻区频段和卡2的邻区频段不进行测量。这样，卡1和卡2能够继续驻留在当前的小区而不进行小区切换，以继续保持双卡的DSDA模式，从而能够保证卡1和卡2均处于连接态，不影响业务的正常进行，以保证良好的用户体验。此外，终端设备对卡1和卡2的邻区频段不进行测量，还能避免由于测量造成的功耗浪费，节省了功耗。
在另一种实现方式中，终端设备对卡1的邻区频段和卡2的邻区频段进行测量，但测量后不上报测量结果。这样，由于终端设备不会上报测量结果，网络设备就不会发起切换请求，终端设备也不会进行小区切换，卡1和卡2能够继续驻留在当前的小区而不进行小区切换，以继续保持双卡的DSDA模式，从而能够保证卡1和卡2均处于连接态，不影响业务的正常进行，以保证良好的用户体验。
在S341中，在卡1的邻区频段和卡2的邻区频段之间能够形成DSDA模式的情况下，终端设备对能够形成DSDA模式的每个卡的初始候选频段进行测量。其中，每个卡的初始 候选频段包括至少一个或多个频段。
在该步骤中，终端设备将卡1的邻区频段和卡2的邻区频段中能够形成DSDA模式的频段分别确定为卡1的初始候选频段和卡2的初始候选频段，对每个卡的初始候选频段中的每个频段进行测量，以得到每个卡的初始候选频段中每个频段的质量，以在满足一定条件时上报测量结果。
示例性地，频段的质量可以采用参考信号接收功率(reference signal receiving power，RSRP)和参考信号接收质量(reference signal receiving quality,RSRQ)中的至少一个来表示。
应理解，上述频段的质量也可以理解为小区的质量，两者可以替换描述。
应理解，一个卡的初始候选频段中的频段是该一个卡的邻区频段中的部分或全部频段。若该一个卡的邻区频段中的所有频段均能够和另一个卡的邻区频段中的至少一个频段形成DSDA模式，则该一个卡的初始候选频段是该一个卡的邻区频段中的全部频段。若该一个卡的邻区频段中的部分频段能够和另一个卡的邻区频段中的至少一个频段形成DSDA模式，则该一个卡的初始候选频段是该一个卡的邻区频段中的部分频段。
还应理解，当卡1的邻区频段和卡2的邻区频段之间能够形成DSDA模式时，可以形成DSDA模式的一个或多个DSDA组合，一个DSDA组合包括卡1的初始候选频段中的一个频段和卡2的初始候选频段中的一个频段。
继续以上述卡1的邻区频段中的频段11和卡2的邻区频段中的频段21可形成DSDA模式的DSDA组合1以及卡1的邻区频段中的频段12和卡2的邻区频段中的频段22可形成DSDA模式的DSDA组合2的例子为例。在DSDA组合1中，频段11是卡1的初始候选频段中的一个频段，频段21是卡2的初始候选频段中的一个频段，在DSDA组合2中，频段12是卡1的初始候选频段中的另一个频段，频段22是卡2的初始候选频段中的另一个频段，所以，卡1的初始候选频段即包括频段11和频段12，且卡1的初始候选频段是卡1的邻区频段中的部分频段，卡2的初始候选频段即包括频段21和频段22，且卡2的初始候选频段是卡2的邻区频段中的全部频段。
在S350中，终端设备确定每个卡的初始候选频段中是否存在满足预设条件的第一候选频段。其中，每个卡的第一候选频段包括至少一个或多个频段。
在该步骤中，终端设备基于在S341中得到的每个卡的初始候选频段中每个频段的质量，确定每个卡的初始候选频段中是否存在满足预设条件的第一候选频段。若每个卡的初始候选频段中存在满足预设条件的第一候选频段，则执行S361，若至少一个卡的初始候选频段中不存在满足预设条件的第一候选频段，则执行S362。
应理解，第一候选频段中的频段是初始候选频段中的部分或全部频段。若初始候选频段中的所有频段均满足预设条件，则第一候选频段的频段为初始候选频段的全部频段；若初始候选频段中的部分频段满足预设条件，则第一候选频段为初始候选频段中的部分频段。
在一些实施例中，预设条件为：每个卡的邻区的质量满足用于小区切换的事件，一个邻区对应一个频段。示例性地，邻区的质量可以采用邻区对应的频段的RSRP和RSRQ中的至少一个表示。
其中，用于小区切换的事件可以是以下任一个事件：A3事件、A4事件、B1事件或B2事件。A3事件表示与服务小区是同系统同频的邻区的质量高于服务小区的质量的事件。A4事件表示与服务小区是同系统异频的邻区的质量高于一个门限的事件。B1事件表示与 服务小区是异系统的邻区的质量高于一个门限的事件。B2事件表示与服务小区是异系统的邻区的质量高于一个门限且服务小区的质量低于另一个门限的事件。
需要说明的是，一个邻区对应一个事件，不同邻区对应的事件可以相同也可以不同，具体以服务小区与邻区的关系而定。例如，若一个邻区是服务小区的同系统同频的小区，则网络设备为该邻区配置A3事件。若一个邻区是服务小区的同系统异频的小区，则网络设备为该邻区配置A4事件。
继续以上述卡1的初始候选频段包括频段11和频段12以及卡2的初始候选频段包括频段21和频段22为例，若卡1的初始候选频段中的频段11和频段12均满足预设条件，则卡1的第一候选频段包括频段11和频段12，是卡1的初始候选频段中的全部频段，若卡2的初始候选频段中只有频段21满足预设条件在，则卡2的第一候选频段包括频段21，是卡1的初始候选频段中的部分频段。
在S362中，在每个卡的初始候选频段中不存在满足预设条件的第一候选频段的情况下，终端设备不上报任一个卡的测量报告。
若确定出卡1和卡2中的其中一个卡的初始候选频段不存在满足预设条件的第一候选频段，另一个卡存在满足预设条件的第一候选频段，即使将另一个卡切换至第一候选频段中的某个频段，卡1和卡2不一定形成DSDA模式，这种小区切换是失败的。所以，终端设备即使测量了卡1和卡2的初始候选频段，也不上报测量报告，网络设备也不会指示小区切换。
若确定出卡1的初始候选频段和卡2的初始候选频段中均不存在满足预设条件的第一候选频段，意味着两个卡的初始候选频段的质量都不好，没必要切换小区。所以，终端设备即使测量了卡1和卡2的初始候选频段，也不上报测量报告，网络设备也不会指示小区切换。
在S361中，在每个卡的初始候选频段中存在满足预设条件的第一候选频段的情况下，终端设备根据基于卡1的第一候选频段和卡2的第一候选频段形成的DSDA模式的至少一个DSDA组合确定目标DSDA组合，目标DSDA组合包括卡1的第一候选频段中的目标频段和卡2的第一候选频段中的目标频段。
在该步骤中，若在S350中确定出每个卡的初始候选频段中存在满足预设条件的第一候选频段，则终端设备根据卡1的第一候选频段和卡2的第一候选频段确定能够形成DSDA模式的至少一个DSDA组合，从该至少一个DSDA组合中确定目标DSDA组合，该目标DSDA组合包括卡1的第一候选频段中的一个频段(记为卡1的目标频段)和卡2的第一候选频段中的一个频段(记为卡2的目标频段)。
若上述至少一个DSDA组合仅有一个DSDA组合，则将这个唯一的一个DSDA组合确定为目标DSDA组合。
若上述至少一个DSDA组合包括多个DSDA组合，则目标DSDA组合为该多个DSDA组合中的某个DSDA组合，该目标DSDA组合可以是该多个DSDA组合中的任一个DSDA组合，也可以是按照规则确定的DSDA组合，此处不做任何限定。
在上述至少一个DSDA组合包括多个DSDA组合的实施例中，可以将该多个DSDA组合中优先级最高的DSDA组合确定为目标DSDA组合。
在一些实施例中，该优先级最高的DSDA组合是该多个DSDA组合中双卡模式的能力 最好的组合。
该实施例是从双卡模式的能力定义DSDA组合优先级。双卡模式的能力越好，DSDA组合的优先级越高，反之，双卡模式的能力越差，DSDA组合的优先级越低。双卡模式的能力由高到低为：DSDA发射独享＞DSDA发射共享＞DR-DSDS＞DSDS，那么，DSDA组合的优先级由高到低可以为：DSDA发射独享＞DSDA发射共享＞DR-DSDS＞DSDS。
在另一些实施例中，该优先级最高的DSDA组合是该多个DSDA组合中双卡的下行传输通道的独立性最好的组合。
这里所说的独立性，表示的是双卡在进行下行传输时，一个卡的下行传输通道不会影响另一个卡的下行传输通道。例如，卡1在频段11上有4个下行传输通道，卡2在频段21上有4个下行传输通道，当卡1驻留在频段11以及卡2驻留在频段21时双卡间形成DSDA组合，卡1和卡2的下行传输通道依然是4个，互不影响，独立性好。再例如，卡1在频段11上有4个下行传输通道，卡2在频段22上有4个下行传输通道，当卡1驻留在频段11以及卡2驻留在频段22时双卡间形成DSDA组合，但是，在这种DSDA组合中，每个卡的下行传输通道由4个变为2个，每个卡的下行传输通道受到了影响。
在S370中，终端设备向网络设备上报每个卡的测量报告。每个卡的测量报告用于指示每个卡的目标频段的质量。
这样，网络设备基于每个卡的测量报告，可以向终端设备发送切换请求，以指示终端设备将每个卡切换至目标频段上。当完成小区切换后，卡1驻留在卡1的目标频段上，卡2驻留在卡2的目标频段上，双卡间形成DSDA模式，卡1和卡2可以继续保持连接态，这样，成功完成了小区切换，保证了用户体验。
在上述方法300中，对于双卡均处于连接态的场景，终端设备先确定双卡的邻区频段之间是否能够形成DSDA模式，以优先保证双卡切换小区后驻留的频段能够形成DSDA模式，然后在双卡的能够形成DSDA模式的初始候选频段中进一步确定满足预设条件(质量要求)的第一候选频段，从每个卡的第一候选频段中确定出包括每个卡的目标频段的目标DSDA组合，进一步保证了切换小区后双卡驻留的频段的质量。
因此，对于双卡均处于连接态的场景，通过上述方法300，不仅能够使得切换小区后双卡驻留的频段继续形成DSDA模式以保持连接态，而且，切换小区后双卡驻留的频段的质量优于双卡之前驻留的频段的质量，提高了信号质量，总体上提高了用户体验。
一般情况下，终端设备有两个主要业务，通话业务和数据业务(即上网业务)，通话业务的优先级高于数据业务的优先级，在前台的通话业务(简称前台通话业务)的优先级高于在后台的通话业务(简称后台通话业务)的优先级。若双卡当前执行的业务的优先级不同，例如，一个卡执行通话业务，另一个卡执行数据业务，若优先考虑双卡切换小区后驻留的频段是否能够形成DSDA模式再考虑质量要求，对于执行通话业务的卡而言，最终确定的目标频段的质量可能并不是所有邻区频段中质量靠前的，所以，执行通话业务的卡的性能可能达不到最优，一定程度上会影响用户体验。
因此，在上述方法300中，在一些实施例中，在执行S330之前，终端设备可以先确定双卡当前执行的业务的优先级是否相同，若双卡当前执行的业务的优先级相同，执行S330以及后续步骤，例如，双卡当前执行的业务均为数据业务。
若双卡当前执行的业务的优先级不同，例如，一个卡执行通话业务，另一个卡执行数 据业务，或者，一个卡执行前台通话业务，另一个卡执行后台通话业务，则执行下文的方法400，参考下文的具体描述。
应理解，上述方法300中步骤的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。例如，步骤S310和步骤S320的执行顺序可以互相调换。
图4是本申请实施例提供的双卡通信的方法400的示意性流程图。同方法300，为了便于描述，以终端设备为例对方法400做详细说明。
在方法400中，卡1为业务优先级高的卡，卡2为业务优先级低的卡。一般情况下，终端设备有两个主要业务，通话业务和数据业务(即上网业务)，而且，通话业务的优先级高于数据业务的优先级，前台通话业务的优先级高于后台通话业务的优先级。
在S410中，终端设备确定双卡均处于连接态。具体描述可参考步骤S310的相关描述，不再赘述。
在S420中，终端设备接收网络设备发送的双卡中每个卡的测量控制信息。
每个卡的测量控制信息用于指示每个卡的邻区频点，具体描述可参考步骤S320的相关描述，不再赘述。
在S430中，终端设备确定双卡当前执行的业务的优先级不同。
其中一个卡当前执行的业务的优先级高，另一个卡当前执行的业务的优先级低。为了便于描述，将业务优先级高的卡记为卡1，将业务优先级低的卡记为卡2。
例如，卡1当前执行通话业务，卡2当前执行数据业务。再例如，卡1当前执行前台通话业务，卡2当前执行后台通话业务。
在S440中，终端设备确定业务优先级高的卡1的邻区频段中满足预设条件1的目标频段1。在该步骤中，终端设备根据卡1的测量控制信息，对卡1的邻区频段对应的邻区频段进行测量，得到邻区频段中每个频段的质量，根据每个频段的质量，确定卡1的邻区频段中满足预设条件1的目标频段1。
示例性地，预设条件1为：卡1的邻区的质量满足用于小区切换的事件，一个邻区对应一个频段。其中，小区的质量可以采用小区对应的频段的RSRP和RSRQ中至少一个表示。关于用于小区切换的事件的具体描述可参考上文S350中的相关描述，不再赘述。
应理解，目标频段1是卡1的邻区频段中满足预设条件1的某个频段，可以是满足预设条件1的任一个频段，本申请实施例不做任何限定。当满足预设条件1的频段包括多个频段时，示例性地，可以将该多个频段中质量最好的频段确定为目标频段1。
在S450中，终端设备确定业务优先级低的卡2的邻区频段中能够与卡1的目标频段1形成终端设备支持的DSDA模式的初始候选频段。其中，卡2的初始候选频段包括一个或多个频段。
应理解，卡2的初始候选频段是卡2的邻区频段中的部分或全部频段。若卡2的邻区频段中的所有频段均能够和卡1的目标频段1形成DSDA模式，则卡2的初始候选频段是卡2的邻区频段中的全部频段。若卡2的邻区频段中的部分频段能够和卡1的目标频段1形成DSDA模式，则卡2的初始候选频段是卡2的邻区频段中的部分频段。
在S460中，终端设备对卡2的初始候选频段进行测量，以得到卡2的初始候选频段中每个频段的质量。关于频段的质量的具体描述可参考上文的相关描述，不再赘述。
在S470中，终端设备确定卡2的初始候选频段中是否存在满足预设条件2的第一候选频段。其中，第一候选频段包括一个或多个频段。
在该步骤中，终端设备基于在S460中得到的卡2的初始候选频段中每个频段的质量，确定卡2的初始候选频段中是否存在满足预设条件2的第一候选频段。若确定卡2的初始候选频段中存在满足预设条件2的第一候选频段，则执行S481，若确定卡2的初始候选频段中不存在满足预设条件2的第一候选频段，则执行S482。
在一些实施例中，预设条件2为：卡2的邻区的质量满足用于小区切换的事件，一个邻区对应一个频段。示例性地，小区的质量采用小区对应的频段的RSRP和RSRQ中的至少一个表示。关于用于小区切换的事件的具体描述可参考上文S350中的相关描述，不再赘述。
应理解，第一候选频段中的频段是初始候选频段中的部分或全部频段。若初始候选频段中的所有频段均满足预设条件，则第一候选频段的频段为初始候选频段的全部频段；若初始候选频段中的部分频段满足预设条件，则第一候选频段为初始候选频段中的部分频段。
在S481中，在卡2的初始候选频段中存在满足预设条件2的第一候选频段的情况下，终端设备从卡2的第一候选频段中确定目标频段2。
若卡2的第一候选频段包括一个频段，则将这个唯一的频段确定为目标频段2。
若卡2的第一候选频段包括多个频段，则将该多个频段中的某个频段确定为目标频段2，该目标频段2可以是该多个频段中的任一个频段，也可以是按照规则确定的某个频段，此处不做任何限定。
在卡2的第一候选频段包括多个频段的实施例中，终端设备将第一候选频段中优先级最高的频段确定为目标频段2。
在一些实施例中，该优先级最高的频段是卡2的第一候选频段中与卡1的目标频段1形成的DSDA模式中双卡模式的能力最好的频段。也就是说，第一候选频段中与目标频段1形成的DSDA模式中双卡模式的能力最好的频段为目标频段2。
该实施例是从双卡模式的能力定义第一候选频段中频段的优先级的。第一候选频段中某个频段与卡1的目标频段1形成的双卡模式的能力越好，该某个频段的优先级越高，反之，第一候选频段中某个频段与卡1的目标频段1形成的双卡模式的能力越差，该某个频段的优先级越低。双卡模式的能力由高到低为：DSDA发射独享＞DSDA发射共享＞DR-DSDS＞DSDS。
在另一些实施例中，该优先级最高的频段是卡2的第一候选频段中质量最好的频段。也就是说，第一候选频段中质量最好的频段为目标频段2。频段的质量可以采用RSRP值和RSRQ值中的至少一个表征。
该实施例是从频段的质量定义第一候选频段中频段的优先级的。第一候选频段中某个频段的质量越好，该某个频段的优先级越高，反之，第一候选频段中某个频段的质量越差，该某个频段的优先级越低。
需要说明的是，上述定义的第一候选频段中频段的优先级可以单独使用，也可以结合使用。
在结合使用上述频段的优先级时，在一些实施例中，将双卡模式的能力与频段的质量结合起来，优先从双卡模式的能力考虑频段的优先级，再从频段的质量考虑频段的优先级。 一般情况下，若第一候选频段中与卡1的目标频段1形成的DSDA模式中双卡模式的能力最好的频段有多个时，可以进一步结合频段的质量确定目标频段2。
在S491中，终端设备上报目标频段1的测量报告和目标频段2的测量报告。
对应地，网络设备基于每个卡的目标频段的测量报告，指示终端设备将每个卡切换至目标频段上，当完成小区切换后，卡1驻留在目标频段1上，卡2驻留在目标频段2上，双卡间形成DSDA模式，卡1和卡2可以继续保持连接态，这样，成功完成了小区切换，保证了用户体验。
在S482中，在卡2的初始候选频段中不存在满足预设条件2的第一候选频段的情况下，终端设备从卡2的初始候选频段中确定目标频段2。
在卡2的初始候选频段中不存在满足预设条件2的第一候选频段的情况下，考虑到卡2当前驻留的频段在后续时段内很可能质量越来越差，即使卡2的初始候选频段不满足质量要求，但考虑到初始候选频段在后续时段有可能质量变好，所以，这种情况下，依然会从初始候选频段中确定目标频段2，以上报给网络设备。
若卡2的初始候选频段包括一个频段，则将这个唯一的频段确定为目标频段2。
若卡2的初始候选频段包括多个频段，则将该多个频段中的某个频段确定为目标频段2，该目标频段2可以是该多个频段中的任一个频段，也可以是按照规则确定的一个频段，此处不做任何限定。
在卡2的初始候选频段包括多个频段的实施例中，终端设备将初始候选频段中优先级最高的频段确定为目标频段2。
在一些实施例中，该优先级最高的频段是卡2的初始候选频段中与卡1的目标频段1形成的DSDA模式中双卡模式的能力最好的频段。也就是说，初始候选频段中与目标频段1形成的DSDA模式中双卡模式的能力最好的频段为目标频段2。
该实施例是从双卡模式的能力定义初始候选频段中频段的优先级的，具体描述可参考上文关于从双卡模式的能力定义第一候选频段中频段的优先级的相关描述，将上文的第一候选频段替换为这里的初始候选频段即可，不再赘述。
在另一些实施例中，该优先级最高的频段是卡2的初始候选频段中质量最好的频段。也就是说，初始候选频段中质量最好的频段为目标频段2。频段的质量可以采用RSRP值和RSRQ值中的至少一个表征。
该实施例是从频段的质量定义初始候选频段中频段的优先级的，具体描述可参考上文关于从频段的质量定义第一候选频段中频段的优先级的相关描述，将上文的第一候选频段替换为这里的初始候选频段即可，不再赘述。
需要说明的是，上述定义的初始候选频段中频段的优先级可以单独使用，也可以结合使用，具体可参考上文关于第一候选频段中频段的优先级的相关描述，将上文的第一候选频段替换为这里的初始候选频段即可，不再赘述。
在S492中，终端设备上报目标频段1的测量报告和目标频段2的测量报告。
具体描述可参考步骤S491的相关描述，不再赘述。
在上述方法400中，对于双卡均处于连接态的场景，当双卡当前执行的业务的优先级不同时，终端设备先从业务优先级高的卡1的邻区频段中确定满足预设条件1的目标频段1，以优先保证业务优先级高的卡1的信号质量，然后再从业务优先级低的卡2的邻区频 段中确定能够与卡1的目标频段1形成DSDA组合的初始候选频段以及从初始候选频段中确定满足预设条件2的第一候选频段，从第一候选频段中确定目标频段2，进一步保证了切换小区后双卡驻留的频段也能够形成DSDA模式以继续保持连接态，总体提高了用户体验。
应理解，上述方法400的过程仅为示意性描述，不应对本申请实施例构成限定。
在一些实施例中，在卡2的初始候选频段中不存在满足预设条件2的第一候选频段的情况下，终端设备可以仅上报目标频段1的测量报告，不上报卡2的任何频段的测量报告。
这样，网络设备基于该测量报告可以指示终端设备将卡1切换至质量好的目标频段1对应的小区，卡2继续驻留在当前小区，虽然卡1进行小区切换后驻留的频段与卡2当前驻留的小区的频段不一定能够形成DSDA模式，但能够优先保证卡1当前执行的业务的质量要求。
还应理解，上述方法400中步骤的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
图5是本申请实施例提供的双卡通信的方法500的示意性流程图。同方法300，为了便于描述，以终端设备为例对方法500做详细说明。
与上述方法300和方法400不同之处在于，方法500描述的是双卡中其中一个卡需要进行小区切换的场景。在方法500中，卡1为主卡和副卡中的其中一个，卡2为主卡和副卡中的另一个，此处不做任何限定。
在S510中，终端设备确定双卡均处于连接态。具体描述可参考步骤S310的相关描述，不再赘述。
在S520中，终端设备接收网络设备发送的卡1的测量控制信息。
测量控制信息用于指示卡1的邻区频点。关于测量控制信息的具体描述可参考S320的相关描述，不再赘述。
在S530中，终端设备确定卡1的邻区频段中能够与卡2当前驻留的频段形成终端设备支持的DSDA模式的初始候选频段。其中，初始候选频段包括一个或多个频段。
在该步骤中，终端设备根据从卡1的测量控制信息确定的卡1的邻区频点确定对应的邻区频段，进而，确定卡1的邻区频段中能够与卡2当前驻留的频段形成终端设备支持的DSDA模式的初始候选频段。
应理解，卡1的初始候选频段是卡1的邻区频段中的部分或全部频段。若卡1的邻区频段中的所有频段均能够和卡2当前驻留的频段形成DSDA模式，则卡1的初始候选频段是卡1的邻区频段中的全部频段。若卡1的邻区频段中的部分频段能够和卡2当前驻留的频段形成DSDA模式，则卡1的初始候选频段是卡1的邻区频段中的部分频段。
在S540中，终端设备从初始候选频段中确定满足预设条件的第一候选频段。其中，初始候选频段包括一个或多个频段。
在该步骤中，终端设备对卡1的初始候选频段进行测量，以得到卡1的初始候选频段中每个频段的质量，从而，确定满足预设条件的第一候选频段。
应理解，第一候选频段中的频段是卡1的初始候选频段中的部分或全部频段。若初始候选频段中的所有频段均满足预设条件，则第一候选频段的频段为初始候选频段的全部频段；若初始候选频段中的部分频段满足预设条件，则第一候选频段为初始候选频段中的部 分频段。
在一些实施例中，预设条件为：卡1的邻区的质量满足用于小区切换的事件，一个邻区对应一个频段。示例性地，邻区的质量可以采用邻区对应的频段的RSRP和RSRQ中的至少一个表示。关于用于小区切换的事件的具体描述可参考上文S350中的相关描述，不再赘述。
在S550中，终端设备从第一候选频段中确定目标频段。
若第一候选频段包括一个频段，则将这个唯一的频段确定为目标频段。
若第一候选频段包括多个频段，则将该多个频段中的某个频段确定为目标频段，该目标频段可以是该多个频段中的任一个频段，也可以是按照规则确定的某个频段，此处不做任何限定。
在第一候选频段包括多个频段的实施例中，终端设备将第一候选频段中优先级最高的频段确定为目标频段。
在一些实施例中，该优先级最高的频段是第一候选频段中与卡2当前驻留的频段形成的DSDA模式中双卡模式的能力最好的频段。也就是说，第一候选频段中与卡2当前驻留的频段形成的DSDA模式中双卡模式的能力最好的频段为目标频段。
在另一些实施例中，该优先级最高的频段是第一候选频段中质量最好的频段。也就是说，第一候选频段中质量最好的频段为目标频段。
需要说明的是，上述第一候选频段中频段的优先级可以单独使用，也可以结合使用。
关于上述从第一候选频段中确定目标频段的具体描述可参考上文的相关描述，不再赘述。
在S560中，终端设备上报目标频段的测量报告，测量报告用于指示目标频段的质量。
对应地，网络设备基于目标频段的测量报告，指示终端设备将卡1切换至目标频段上，当完成小区切换后，卡1驻留在目标频段1上，卡2依然驻留在当前频段上，双卡间形成DSDA模式，卡1和卡2可以继续保持连接态，这样，成功完成了小区切换，保证了用户体验。
在上述方法500中，终端设备先确定需要进行邻区测量的卡1的邻区频段中与卡2当前驻留的频段是否能够形成DSDA模式，以优先保证卡1切换小区后驻留的频段能够和卡2当前驻留的频段依然形成DSDA模式，然后在卡1的能够形成DSDA模式的初始候选频段中进一步确定满足预设条件(质量要求)的第一候选频段，从第一候选频段中确定目标频段，进一步保证了切换小区后卡1驻留的频段的质量。这样，不仅能够使得卡1切换小区后卡1驻留的频段能够和卡2当前驻留的频段继续形成DSDA模式以保持连接态，而且，切换小区后的卡1驻留的频段的质量优于之前驻留的频段的质量，提高了信号质量，总体上提高了用户体验。
图6是本申请实施例提供的双卡通信的方法600的示意性流程图。该方法600可由支持双卡通信的终端设备执行，也可由终端设备中的芯片执行，本申请实施例不做任何限定。为了便于描述，以终端设备为例对方法600做详细说明。
方法600所示的实施例是双卡进行小区切换的场景，通过相关设计尽可能使得切换小区后双卡驻留的频段间依然形成DSDA模式以继续保持连接态，不影响每个卡的业务的正常进行，以提高用户体验。
在方法600中，终端设备的第一卡和第二卡均处于连接态，第一卡可以为主卡和副卡中的一个卡，第二卡为主卡和副卡中的另一个卡。此外，方法600可类比于方法300，第一卡可以类比于方法300中的卡1，第二卡可以类比于方法300中的卡2。
当第一卡和第二卡均处于连接态时，意味着第一卡和第二卡均可独立进行上行传输和下行传输，而只有当第一卡和第二卡之间形成DSDA模式的情况下才会使得第一卡和第二卡处于连接态。所以，当第一卡和第二卡均处于连接态时，第一卡和第二卡之间必然已形成DSDA模式，即终端设备处于DSDA模式。因此，当第一卡和第二卡均处于连接态时也相当于第一卡和第二卡之间形成DSDA模式。
在S610中，终端设备确定第一卡的邻区频段和第二卡的邻区频段之间是否能够形成终端设备支持的双卡双通DSDA模式。其中，第一卡的邻区频段包括至少一个频段，第二卡的邻区频段包括至少一个频段。
在该步骤中，终端设备可以根据网络设备发送的第一卡的测量控制信息确定第一卡的邻区频点，根据网络设备发送的第二卡的测量控制信息确定第二卡的邻区频点，邻区频点表示每个卡当前驻留的小区(即，服务小区)的邻区的频点，邻区频点包括至少一个频点，至少一个频点与至少一个邻区一一对应，一个频点对应一个邻区，因此，根据第一卡的邻区频点可以确定第一卡的邻区频段，根据第二卡的邻区频点可以确定第二卡的邻区频段，根据终端设备的DSDA模式信息，确定第一卡的邻区频段和第二卡的邻区频段之间是否能够形成终端设备支持的DSDA模式。
DSDA模式信息用于指示终端设备支持的能够形成DSDA模式的所有DSDA组合，每个DSDA组合包括双卡的网络类型和频段。实现中，可以在终端设备中预配置DSDA模式信息。
应理解，同一个终端设备支持的DSDA组合是固定的，不同终端设备支持的DSDA组合可以相同也可以不同，具体可以根据终端设备的型号或硬件信息确定。具体描述可参考上文的相关描述，不再赘述。
上述网络设备包括一个或多个基站，第一卡的测量控制信息和第二卡的测量控制信息可以是同一个基站发送的也可以是不同基站发送的，主要视第一卡和第二卡驻留的网络是否相同以及是否支持相同的运营商的情况而定，具体描述可参考上文S320的相关描述，将上文的卡1和卡2分别替换为第一卡和第二卡即可，不再赘述。
在S620中，终端设备对能够形成DSDA模式的第一卡和第二卡中每个卡的初始候选频段进行测量。
若第一卡的邻区频段和第二卡的邻区频段之间能够形成终端设备支持的DSDA模式，意味着第一卡和第二卡进行小区切换后有机会继续形成DSDA模式以继续保持双卡的连接态，能够成功实现小区的切换。因此，在该步骤中，在第一卡的邻区频段和第二卡的邻区频段之间能够形成DSDA模式的情况下，将第一卡的邻区频段和第二卡的邻区频段中能够形成DSDA模式的频段分别确定为第一卡的初始候选频段和第二卡的初始候选频段，对每个卡的初始候选频段中的每个频段进行测量，以得到每个卡的初始候选频段中每个频段的质量，以在满足一定条件时上报测量结果。
当第一卡的邻区频段和第二卡的邻区频段之间能够形成DSDA模式时，可以形成DSDA模式的一个或多个DSDA组合，一个DSDA组合包括第一卡的初始候选频段中的一 个频段和第二卡的初始候选频段中的一个频段。
应理解，每个卡的初始候选频段中的频段是该每个卡的邻区频段中的部分或全部频段。若一个卡的邻区频段中的所有频段均能够和另一个卡的邻区频段中的至少一个频段形成DSDA模式，则该一个卡的初始候选频段是该一个卡的邻区频段中的全部频段。若该一个卡的邻区频段中的部分频段能够和另一个卡的邻区频段中的至少一个频段形成DSDA模式，则该一个卡的初始候选频段是该一个卡的邻区频段中的部分频段。
示例性地，频段的质量可以采用RSRP和RSRQ中的至少一个来表示。
应理解，上述频段的质量也可以理解为频段对应的小区的质量，两者可以替换描述。
以下，举例说明终端设备确定每个卡的初始候选频段的过程。
假设，第一卡驻留在网络1，第一卡的邻区频段包括网络1的3个频段，分别是：频段11、频段12、频段14，第二卡驻留在网络2，第二卡的邻区频段包括网络2的2个频段，分别是频段21和频段22，终端设备的DSDA模式信息指示的终端设备支持的DSDA模式的所有DSDA组合包括3个DSDA组合，分别是：由“网络1频段11+网络2频段21”形成的DSDA组合1，以及，由“网络1频段12+网络2频段22”形成的DSDA组合2，由“网络1频段14+网络2频段23”形成的DSDA组合3。可以看出，第一卡的邻区频段中的频段11和第二卡的邻区频段中的频段21可形成DSDA组合1，第一卡的邻区频段中的频段12和第二卡的邻区频段中的频段22可形成DSDA组合2，所以，第一卡的邻区频段和第二卡的邻区频段能够形成DSDA模式，且可形成DSDA模式的2个DSDA组合。在DSDA组合1中，频段11是第一的初始候选频段中的一个频段，频段21是第二卡的初始候选频段中的一个频段，在DSDA组合2中，频段12是第一卡的初始候选频段中的另一个频段，频段22是第二卡的初始候选频段中的另一个频段，所以，第一卡的初始候选频段即包括频段11和频段12，且第一卡的初始候选频段是第一卡的邻区频段中的部分频段，第二卡的初始候选频段即包括频段21和频段22，且第二卡的初始候选频段是第二卡的邻区频段中的全部频段。
在S630中，终端设备确定每个卡的初始候选频段中满足预设条件的第一候选频段，该预设条件包括：该每个卡的邻区的质量满足用于小区切换的事件，一个邻区对应一个频段。其中，第一候选频段包括至少一个频段。
在该步骤中，终端设备基于在S620中得到的每个卡的初始候选频段中每个频段的质量，根据预设条件，确定每个卡的初始候选频段中满足预设条件的第一候选频段。
在预设条件中，示例性地，邻区的质量可以采用邻区对应的频段的RSRP和RSRQ中的至少一个表示。而且，用于小区切换的事件的可以是以下任一个事件：A3事件、A4事件、B1事件或B2事件，关于各个事件的具体描述可参考上文的相关描述，不再赘述。
应理解，第一候选频段中的频段是初始候选频段中的部分或全部频段。若初始候选频段中的所有频段均满足预设条件，则第一候选频段的频段为初始候选频段的全部频段；若初始候选频段中的部分频段满足预设条件，则第一候选频段为初始候选频段中的部分频段。
在S640中，终端设备根据基于第一卡的第一候选频段和第二卡的第一候选频段之间形成的DSDA模式的至少一个DSDA组合，确定目标DSDA组合，该目标DSDA组合包括该第一卡的第一候选频段中的目标频段和该第二卡的第一候选频段中的目标频段。
在该步骤中，若在S640中确定出每个卡的初始候选频段中存在满足预设条件的第一 候选频段，则终端设备根据第一卡的第一候选频段和第二卡的第一候选频段确定能够形成DSDA模式的至少一个DSDA组合，从该至少一个DSDA组合中确定目标DSDA组合。
在上述至少一个DSDA组合中，一个DSDA组合包括第一卡的第一候选频段中的一个频段和第二卡的第一候选频段中的一个频段。对于目标DSDA组合，将目标DSDA组合中包括的第一卡的第一候选频段中的一个频段记为第一卡的目标频段，将目标DSDA组合中包括的第二卡的第一候选频段中的一个频段记为第二卡的目标频段。
若上述至少一个DSDA组合仅有一个DSDA组合，则将这个唯一的一个DSDA组合确定为目标DSDA组合。
若上述至少一个DSDA组合包括多个DSDA组合，则目标DSDA组合为该多个DSDA组合中的某个DSDA组合，该目标DSDA组合可以是该多个DSDA组合中的任一个DSDA组合，也可以是按照规则确定的DSDA组合，此处不做任何限定。
在一些实施例中，该至少一个DSDA组合包括多个DSDA组合；以及，该根据基于该第一卡的第一候选频段和该第二卡的第一候选频段之间形成的DSDA模式的至少一个DSDA组合，确定目标DSDA组合，包括：将该至少一个DSDA组合中优先级最高的DSDA组合确定为该目标DSDA组合。
这样，终端设备通过将优先级最高的DSDA组合作为目标DSDA组合，能够使得进行小区切换后第一卡和第二卡驻留的频段之间形成的DSDA模式是终端设备设定的最优模式，提高了双卡模式的性能。
在一示例中，该目标DSDA组合是该多个DSDA组合中双卡模式的能力最好的组合。
该实施例中是从双卡模式的能力定义DSDA组合的优先级，具体描述可参考上文S361中的相关描述，将上文的卡1和卡2分别替换为这里的第一卡和第二卡即可，不再赘述。
通过将多个DSDA组合中双卡模式的能力最好的组合确定为目标DSDA组合，终端设备根据该目标DSDA组合对第一卡和第二卡进行小区切换后，能够使得进行小区切换后第一卡和第二卡驻留的频段之间形成的DSDA模式是性能最好的双卡模式，用户的体验最好。
在另一示例中，该目标DSDA组合是该多个DSDA组合中双卡的下行传输通道的独立性最好的组合。
这里所说的独立性，表示的是双卡在DSDA模式下进行下行传输时，一个卡的下行传输通道不会影响另一个卡的下行传输通道，每个卡的下行传输通道均不会减少。关于该实施例的描述可参考上文S361中的相关描述，将上文的卡1和卡2分别替换为这里的第一卡和第二卡即可，不再赘述。
通过将多个DSDA组合中双卡的下行传输通道的独立性最高的组合确定为目标DSDA组合，终端设备根据该目标DSDA组合对第一卡和第二卡进行小区切换后，第一卡和第二卡驻留的频段不仅能够形成DSDA模式，而且，尽可能不会使得每个卡的下行传输通道减少，提高传输效率。
在S650中，终端设备上报测量报告，该测量报告用于指示第一卡的目标频段的质量和第二卡的目标频段的质量。
对应地，网络设备可以基于测量报告，向终端设备发送切换请求，以指示终端设备将每个卡切换至对应的目标频段上。当完成小区切换后，第一卡驻留在第一卡的目标频段上，第二卡驻留在第二卡的目标频段上，双卡间形成DSDA模式以继续保持连接态，这样，成 功完成了小区切换，保证了用户体验。
示例性地，测量报告可以包括针对第一卡的第一测量报告和针对第二卡的第二测量报告，第一测量报告用于指示第一卡的目标频段的质量，第二测量报告用于指示第二卡的目标频段的质量。这样，终端设备可以将第一测量报告和第二测量报告分别上报给网络设备。
本申请实施例提供的双卡通信的方法，在第一卡和第二卡均处于连接态的情况下，第一卡和第二卡之间形成DSDA模式，当需要进行小区切换时，首先确定第一卡的邻区频段和第二卡的邻区频段之间是否能够形成终端设备支持的DSDA模式，在能够形成DSDA模式的情况下继续执行后续步骤，以优先保证第一卡和第二卡切换小区后驻留的小区的频段之间依然能够形成DSDA模式，随后，对能够形成DSDA模式的每个卡的初始候选频段进行测量、从每个卡的初始候选频段中确定满足预设条件(即，质量要求)的第一候选频段以及从第一卡和第二卡的第一候选频段中确定出包括每个卡的目标频段的目标DSDA组合，向网络设备上报测量报告，以便于网络设备指示终端设备将第一卡和第二卡分别切换至对应的目标频段上，进一步保证了切换小区后第一卡和第二卡驻留的小区的频段的质量。综上，上述方法不仅能够使得切换小区后第一卡和第二卡驻留的频段继续形成DSDA模式以保持连接态，不影响每个卡的业务的正常进行，而且，切换小区后第一卡和第二卡驻留的频段的质量优于第一卡和第二卡之前驻留的频段的质量，提高了信号质量，总体上提高了用户体验。
在一些实施例中，在该确定该第一卡的邻区频段和该第二卡的邻区频段之间是否能够形成该终端设备支持的双卡双通DSDA模式之前，方法600还包括：
终端设备确定该第一卡当前执行的业务的优先级与该第二卡当前执行的业务的优先级相同。
示例性地，该第一卡和该第二卡当前执行的业务均为数据业务。
若第一卡和第二卡当前执行的业务的优先级不同，例如，一个卡执行通话业务，另一个卡执行数据业务，通话业务的优先级高于数据业务的优先级，若优先考虑第一卡和第二卡切换小区后驻留的频段是否能够形成DSDA模式再考虑质量要求，对于执行通话业务的卡而言，最终确定的目标频段的质量可能并不是所有邻区频段中质量靠前的，所以，执行通话业务的卡的性能可能达不到最优，一定程度上会影响用户体验。因此，在第一卡当前执行的业务的优先级与第二卡当前执行的业务的优先级相同的情况下，先确定第一卡和第二卡切换小区后驻留的频段是否能够形成DSDA模式再考虑质量要求，能够避免出现由于某个卡当前执行的业务的优先级高但切换小区后该某个卡驻留的频段的质量并不是很好的情况，从而在一定程度上影响用户体验。
在以上实施例中，描述的是在第一卡的邻区频段与第二卡的邻区频段能够形成DSDA模式的情况下终端设备的行为，在一些实施例中，方法600还包括：
在该第一卡的邻区频段和该第二卡的邻区频段无法形成该终端设备支持的DSDA模式的情况下，终端设备对该每个卡的邻区频段不进行测量。
由于第一卡的邻区频段和第二卡的邻区频段之间无法形成DSDA模式，意味着第一卡和第二卡进行小区切换后是无法形成DSDA模式的，从而无法保证双卡依然处于连接态，这样的小区切换是失败的。因此，终端设备对每个卡的邻区频段不进行测量。
这样，第一卡和第二卡能够继续驻留在当前的小区而不进行小区切换，以继续保持双 卡的DSDA模式，从而能够保证第一卡和第二卡继续处于连接态，一定程度上不影响业务的正常进行，以尽可能保证良好的用户体验。此外，终端设备对每个卡的邻区频段不进行测量，还能避免由于无效的测量造成的功耗浪费，节省了功耗。
在另一些实施例中，在该第一卡的邻区频段和该第二卡的邻区频段无法形成该终端设备支持的DSDA模式的情况下，终端设备对该每个卡的邻区频段进行测量，但不上报测量报告。
这样，由于终端设备不会上报测量结果，网络设备就不会发起切换请求，终端设备也不会进行小区切换，第一卡和第二卡能够继续驻留在当前的小区而不进行小区切换，以继续保持双卡的DSDA模式，从而能够保证第一卡和第二卡继续处于连接态，一定程度上不影响业务的正常进行，以保证良好的用户体验。
图7是本申请实施例提供的双卡通信的方法700的示意性流程图。该方法600可由支持双卡通信的终端设备执行，也可由终端设备中的芯片执行，本申请实施例不做任何限定。为了便于描述，以终端设备为例对方法700做详细说明。
方法700的双卡均处于连接态，与方法600不同之处在于，双卡当前执行的业务的优先级不同，第一卡是业务优先级高的卡，第二卡是业务优先级低的卡，需要先确定业务优先级高的第一卡的邻区频段中质量好的第一目标频段，基于第一目标频段，从业务优先级的第二卡的邻区频段中匹配能够和第一目标频段形成DSDA模式的第二目标频段，以优先保证切换小区后业务优先级高的第一卡驻留的频段的质量，也能保证切换小区后双卡驻留的频段形成DSDA模式以继续保持连接态，不影响每个卡的业务的正常进行，以更好地提高用户体验。
此外，方法700可类比于方法400，第一卡可类比于方法400中的卡1，第二卡可类比于方法400的卡2。
在S710中，在双卡当前执行的业务的优先级不同的情况下，终端设备确定双卡中第一卡的邻区频段中满足第一预设条件的第一目标频段，该第一卡当前执行的业务的优先级高于该双卡中第二卡当前执行的业务的优先级，该第一预设条件包括：该第一卡的邻区的质量满足用于小区切换的事件，一个邻区对应一个频段。
在该步骤之前，终端设备会确定双卡当前执行的业务的优先级是否相同，在双卡当前执行的业务的优先级不同的情况下，确定双卡中业务优先级高的第一卡的邻区频段中满足第一预设条件的第一目标频段，以找出质量好的频段。
当第一卡的邻区频段中满足第一预设条件的频段包括多个频段时，可以将该多个频段中质量最好的频段确定为第一目标频段。
在第一预设条件中，示例性地，邻区的质量可以采用邻区对应的频段的RSRP和RSRQ中的至少一个表示。而且，用于小区切换的事件的可以是以下任一个事件：A3事件、A4事件、B1事件或B2事件，关于各个事件的具体描述可参考上文的相关描述，不再赘述。
在一些实施例中，第一卡当前执行的业务是通话业务，第二卡当前执行的业务是数据业务。
在另一些实施例中，第一卡当前执行的业务是在前台进行的通话业务，第二卡当前执行的业务是在后台进行的通话业务。
在S720中，终端设备确定该第二卡的邻区频段中能够与该第一目标频段形成该终端 设备支持的双卡双通DSDA模式的初始候选频段。其中，第二卡的初始候选频段包括一个或多个频段。
关于S720的具体描述可参考S450的相关描述，将S450中的卡1和卡2分别替换为这里的第一卡和第二卡即可，不再赘述。
在S730中，终端设备确定该第二卡的初始候选频段中满足第二预设条件的第一候选频段，该第二预设条件包括：该第二卡的邻区的质量满足用于小区切换的事件，一个邻区对应一个频段。其中，第二卡的第一候选频段包括一个或多个频段。
在第二预设条件中，示例性地，邻区的质量可以采用邻区对应的频段的RSRP和RSRQ中的至少一个表示。而且，用于小区切换的事件的可以是以下任一个事件：A3事件、A4事件、B1事件或B2事件，关于各个事件的具体描述可参考上文的相关描述，不再赘述。
应理解，第一候选频段中的频段是初始候选频段中的部分或全部频段。若初始候选频段中的所有频段均满足预设条件，则第一候选频段的频段为初始候选频段的全部频段；若初始候选频段中的部分频段满足预设条件，则第一候选频段为初始候选频段中的部分频段。
在S740中，终端设备上报测量报告，该测量报告用于指示该第一目标频段的质量和基于该第一候选频段确定的第二目标频段的质量。
对应地，网络设备可以基于测量报告，向终端设备发送切换请求，以指示终端设备将每个卡切换至对应的目标频段上。当完成小区切换后，第一卡驻留在第一目标频段上，第二卡驻留在第二目标频段上，双卡间形成DSDA模式以继续保持连接态，这样，成功完成了小区切换，保证了用户体验。
示例性地，测量报告可以包括针对第一卡的第一测量报告和针对第二卡的第二测量报告，第一测量报告用于指示第一卡的第一目标频段的质量，第二测量报告用于指示第二卡的第二目标频段的质量。这样，终端设备可以将第一测量报告和第二测量报告分别上报给网络设备。
应理解，在终端设备上报测量报告之前，方法700还包括：从第一候选频段中确定第二目标频段。第二目标频段是第一候选频段中的某个频段，可以是任一个频段，也可以是按照某种规则确定的频段，此处不做限定，后续做具体说明。
本申请实施例提供的双卡通信的方法，在双卡均处于连接态的情况下，当双卡当前执行的业务的优先级不同时，终端设备先从业务优先级高的第一卡的邻区频段中确定满足第一预设条件(质量要求)的第一目标频段，以优先保证业务优先级高的第一卡的质量，然后再从业务优先级低的第二卡的邻区频段中确定能够与第一目标频段形成DSDA模式的初始候选频段以及从初始候选频段中确定满足第二预设条件(质量要求)的第一候选频段，从第一候选频段中确定第二目标频段，进一步保证了切换小区后双卡驻留的频段也能够形成DSDA模式以继续保持连接态，总体提高了用户体验。综上，上述方法不仅优先保证了业务优先级高的第一卡的质量，而且，能够使得切换小区后双卡驻留的频段继续形成DSDA模式以保持连接态，不影响每个卡的业务的正常进行，此外，切换小区后双卡驻留的频段的质量均优于双卡之前驻留的频段的质量，提高了信号质量，总体上更好地提高了用户体验。
在一些实施例中，该第一候选频段包括多个频段；以及，在该上报测量报告之前，方法700还包括：终端设备将该第一候选频段中优先级最高的频段确定为该第二目标频段。
这样，终端设备对双卡进行小区切换后，双卡分别驻留的第一目标频段和第二目标频段之间形成的DSDA模式是终端设备设定的最优模式，提高了双卡模式的性能。
在一示例中，该第二目标频段与该第一目标频段形成的DSDA模式的DSDA组合是该第一候选频段中各个频段与该第一目标频段形成的各个DSDA组合中双卡能力最好的组合。
也就是说，终端设备将第一候选频段中各个频段与该第一目标频段形成的各个DSDA组合中双卡能力最好的组合中第一候选频段包括的频段确定为第二目标频段。该实施例是从双卡模式的能力定义第一候选频段中频段的优先级的，第一候选频段中某个频段与第一目标频段形成的双卡模式的能力越好，该某个频段的优先级越高，反之，第一候选频段中某个频段与第一目标频段形成的双卡模式的能力越差，该某个频段的优先级越低。双卡模式的能力由高到低为：DSDA发射独享＞DSDA发射共享＞DR-DSDS＞DSDS。
例如，第一候选频段中包括3个频段，该3个频段与第一目标频段可以形成3个DSDA组合，其中，DSDA组合1是DSDA发射独享模式，DSDA组合2和DSDA组合3是DSDA发射共享模式，那么，DSDA模式为DSDA发射独享模式的DSDA组合1是3个DSDA组合中双卡能力最好的组合，DSDA组合1中包括的第一候选频段中的频段即为第二目标频段。
本申请实施例提供的双卡通信的方法，终端设备通过将第一候选频段中各个频段与第一目标频段形成的各个DSDA组合中双卡能力最好的组合中第一候选频段包括的频段确定为第二目标频段，对双卡进行小区切换后，双卡分别驻留的第一目标频段和第二目标频段之间形成的DSDA模式是性能最优的双卡模式，用户的体验最好。
在另一示例中，第二目标频段是该第一候选频段中质量最好的频段。
也就是说，终端设备将第一候选频段中质量最好的频段为第二目标频段。频段的质量可以采用RSRP值和RSRQ值中的至少一个表征。该实施例是从频段的质量定义第一候选频段中频段的优先级的。第一候选频段中某个频段的质量越好，该某个频段的优先级越高，反之，第一候选频段中某个频段的质量越差，该某个频段的优先级越低。
需要说明的是，上述定义的第一候选频段中频段的优先级可以单独使用，也可以结合使用，具体描述可参考上文S481的相关描述，不再赘述。
以上，结合图1至图7，详细说明了本申请实施例提供的双卡通信的方法，下面将结合图8至图9，详细描述根据本申请实施例提供的终端设备。
图8是本申请实施例提供的终端设备800的示例性框图。该终端设备800包括处理单元810。
