Description

终端设备和无线通信的方法
本申请要求于2019年11月20日提交中国专利局、申请号为201911141103.9、申请名称为“终端设备和无线通信的方法”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
申请涉及电子设备领域，更具体地，涉及一种终端设备和无线通信的方法。
背景技术
现有的通信系统中，为了提高数据的传输速率，可以将终端设备同时与多个接入网设备通信连接，以实现数据的传输。例如，现有的5G的非独立组网(non-standalone，NSA)可以支持终端设备同时与两个接入网设备通信连接，其中一个接入网设备支持新空口(new radio,NR)网络，另一个接入网设备支持长期演进(long term evolution，LTE)网络。以上行传输为例，终端设备需要通过两个接入网设备将数据发送至核心网设备。相比于传统的一个终端设备与一个接入网设备通信连接的方式，这种一个终端设备与多个接入网设备通信的方式会不可避免地增加终端设备的功耗。
基于此，本申请需要提供一种技术，在尽可能不影响用户对传输速率的用户体验的情况下，可以减少终端设备的功耗。
发明内容
本申请提供一种终端设备和无线通信的方法，在终端设备处于包括LTE链路和NR链路的双连接网络中，终端设备可以根据与实际传输速率相关的业务传输速率确定是否断开NR链路，若业务传输速率较小，断开NR链路；若业务传输速率较大，则不断开第一链路，同时采用NR链路和LTE链路进行通信。这样，在不影响速率方面的用户体验的情况下，可以有效地降低终端设备的功耗，提高了功耗方面的用户体验，一定程度上平衡了用户对传输速率和功耗的体验。
第一方面，提供了一种终端设备，所述终端设备包括：
处理器；
计算机存储介质，所述计算机存储介质包括指令，当所述处理器执行所述指令时，使得所述终端设备执行以下动作：
驻留双连接网络，所述双连接网络包括长期演进LTE链路和新空口NR链路；
在检测到所述终端设备的业务传输速率小于第一开关门限的情况下，发送第一指令，所述第一指令用于释放所述NR链路，所述业务传输速率与实际传输速率相关；
在所述NR链路断开之后，通过所述LTE链路进行通信。
其中，LTE链路也可以称为4G链路，NR链路也可以称为5G链路。
本申请的双连接网络表示基于双连接方式进行通信的网络，双连接方式表示终端设备与两个接入网设备通信连接，终端设备与支持LTE技术的4G接入网设备之间的链路是LTE链路，终端设备与支持NR技术的5G接入网设备之间的链路是NR链路。
驻留双连接网络可以理解为终端设备与4G接入网设备和5G接入网设备通信连接，通过LTE链路和NR链路进行通信。
在一种可能的实现方式中，业务传输速率可以是终端设备的实际传输速率。
在另一种可能的实现方式中，业务传输速率也可以是对实际传输速率做处理后的速率。示例性地，业务传输速率可以是对实际传输速率做平滑处理后的速率。
可选地，终端设备可以在检测到终端设备的一个或多个业务传输速率小于第一开关门限的情况下，发送该第一指令。
示例性地，该多个业务传输速率可以是连续的N个业务传输速率。
示例性地，N＝5。
在一种可能的实现方式中，终端设备可以向4G接入网设备发送第一指令，4G接入网设备将该第一指令发送给5G接入网设备，5G接入网设备根据该第一指令释放NR链路。
示例性地，该第一指令可以是辅小区组(secondary cell group，SCG)失败信息(SCG failure information)。
在另一种可能的实现方式中，终端设备可以向5G接入网设备发送该第一指令，5G接入网设备根据该第一指令释放NR链路。
因此，本申请提供的终端设备，在终端设备处于双连接网络时，终端设备可以根据与实际传输速率相关的业务传输速率确定是否断开NR链路，在终端设备的业务传输速率小于第一开关门限的情况下，发送第一指令以断开NR链路。这样，在不影响速率方面的用户体验的情况下，可以有效地降低终端设备的功耗，提高了功耗方面的用户体验，一定程度上平衡了用户对传输速率和功耗的体验。
可选地，当所述处理器执行所述指令时，使得所述终端设备还执行以下动作：
在发送所述第一指令之前，在前台运行第一应用，所述第一应用为预设应用。
换言之，当在前台运行的第一应用为预设应用的情况下，终端设备检测业务传输速率，后续，在检测到业务传输速率小于第一开关门限的情况下，发送第一指令。
对应地，当在前台运行的第一应用是非预设应用的情况下，终端设备不检测业务传输速率，采用LTE链路和NR链路进行通信。
示例性地，预设应用的业务传输速率小于非预设应用的业务传输速率。
例如，预设应用的业务传输速率较小，小于第一阈值，非预设应用的业务传输速率较大，大于该第一阈值。
这样，通过设置预设应用，在第一应用为预设应用的情况下检测终端设备的业务传输速率以确定是否断开NR链路，以在业务传输速率小于第一开关门限情况下断开NR链路，在不影响速率方面的用户体验的情况下，可以有效地降低终端设备的功耗，而且，对应地，可以在第一应用是非预设应用的情况下，不检测终端设备的业务传输速率，采用LTE链路和NR链路进行通信，以尽可能优先保证用户对非预设应用的速率需求，不影响用户对5G通信的体验。
可选地，所述终端设备未处于优先模式，所述优先模式包括以下至少一项：通话模式、 充电模式、性能优化模式或热点共享模式。
换言之，当在前台运行的第一应用为预设应用且终端设备未处于优先模式的情况下，终端设备检测业务传输速率，后续，在检测到业务传输速率小于第一开关门限的情况下，发送第一指令。
通话模式表示终端设备处于处理通话业务的状态。充电模式表示终端设备处于被充电的状态。性能优化模式表示终端设备被设置在能够让终端设备处于性能最优的状态，这种性能最优的状态可以包括网络的传输速率较高的状态。热点共享模式表示终端设备处于将移动数据的流量分享给其他设备使用的模式。
这样，通过设置预设应用以及优先模式，当在前台运行的第一应用为预设应用且终端设备未处于优先模式的情况下，终端设备检测业务传输速率以断开NR链路，可以使得终端设备在优先模式下不需要断开NR链路，尽最大可能满足传输速率的需求。
可选地，当所述处理器执行所述指令时，使得所述终端设备还执行以下动作：
在发送所述第一指令之前，从前台退出所述第一应用；
接入网络设备为所述终端设备配置的小区，以恢复所述NR链路；
在所述NR链路恢复之后，采用所述LTE链路和所述NR链路进行通信。
换言之，在第一应用退出前台后，终端设备恢复NR链路，采用LTE链路和NR链路进行通信。
其中，网络设备为5G接入网设备。
关于终端设备恢复NR链路的过程可以有以下两种实现方式。
在一种可能的实现方式中，4G接入网设备周期性地发送信令以指示终端设备测量多个5G小区以建立NR链路，例如，该信令可以是RRC连接重配置(RRC connection reconfiguration)信息，该RRC连接重配置信息用于配置终端设备需要测量的5G小区，也可以记为测量配置(measure configuration)。若终端设备确定不需要恢复NR链路，则不需要基于该信令进行5G小区的测量。若终端设备确定需要恢复NR链路，则可以根据该信令测量该多个5G小区，向4G接入网设备上报满足条件的5G小区的测量报告(measurement report)，该条件可以是例如被测量小区的信号强度满足要求等，4G接入网设备将满足条件的5G小区的测量报告发送给5G接入网设备，5G接入网设备根据该测量报告为终端设备配置小区，通过4G接入网设备向终端设备发送小区配置信息，例如，该小区配置信息可以是RRC连接重配置(RRC connection reconfiguration)信息，该RRC连接重配置信息用于配置终端设备接入的小区，也可以记为SCG配置(SCG configuration)，终端设备根据该小区配置信息接入5G接入网设备为其配置的小区，完成NR链路的建立。
在另一种可能的实现方式中，4G接入网设备周期性地发送信令以指示终端设备测量多个5G小区以建立NR链路，若终端设备确定不需要恢复NR链路，则不需要基于该信令进行5G小区的测量，若终端设备确定需要恢复NR链路，终端设备向4G接入网设备发送第二指令，该第二指令用于指示5G接入网设备恢复NR链路。4G接入网设备向5G接入网设备转发该第二指令，并且，4G接入网设备开始向终端设备发送信令以指示终端设备测量多个5G小区以恢复NR链路，后续的具体步骤与第一种可能的实现方式相同，不再赘述。
可选地，当所述处理器执行所述指令时，使得所述终端设备还执行以下动作：
在前台运行第二应用，所述第二应用为非预设应用；
继续采用所述LTE链路和所述NR链路进行通信。
可选地，当所述处理器执行所述指令时，使得所述终端设备备还执行以下动作：
在前台运行所述第一应用之后，启动第一定时器；
在所述第一定时器超时后，检测所述终端设备的业务传输速率。
换言之，在第一定时器的时长内，终端设备继续采用当前状态的链路进行通信，对NR链路不做任何判断处理，在第一定时器超时后检测终端设备的业务传输速率。
例如，若当前状态仅包括LTE链路，则在第一定时器的时长内采用LTE链路进行通信。再例如，若当前状态包括LTE链路和NR链路，则在第一定时器的时长内采用LTE链路和NR链路进行通信。
这样，通过设置第一定时器，在前台运行第一应用后开启第一定时器，且在第一定时器超时后，检测所述终端设备的业务传输速率以确定是否断开NR链路，可以避免由于用户在切换应用前后的短时间内恢复和断开NR链路造成的乒乓效应，以进一步提高用户体验。
可选地，所述第一应用为以下任一项应用：导航类应用、阅读类应用、游戏类应用、可内嵌视频的应用。
可选地，所述第一开关门限与所述终端设备在LTE网络中的以下至少一项参数相关，所述LTE网络包括所述LTE链路：
所述终端设备所在的小区的信号强度；或，
所述终端设备所在的小区的小区带宽；或，
所述终端设备进行通信所采用的双工模式，所述双工模式包括时分双工TDD模式或频分双工FDD模式；或，
所述终端设备进行通信所采用的传输模式，所述传输模式包括上行传输或下行传输。
也就是说，第一开关门限可以根据上述至少一项参数不断变化，以更加合理地断开或恢复NR链路，满足用户需求。例如，在信号条件不好的情况下，第一开关门限降低，可以不需要断开NR链路，以尽可能满足用户的速率需求。
可选地，当所述处理器执行所述指令时，使得所述终端设备还执行以下动作：
在发送所述第一指令之后，在检测到所述终端设备的业务传输速率大于第二开关门限的情况下，接入网络设备为所述终端设备配置的小区，以恢复所述NR链路；
在所述NR链路恢复之后，采用LTE链路和NR链路进行通信。
换言之，在NR链路被断开后，终端设备通过业务传输速率和第二开关门限以进一步确定是否需要恢复NR链路。
可选地，终端设备可以在检测到终端设备的一个或多个业务传输速率大于第二开关门限的情况下，接入网络设备为所述终端设备配置的小区，以恢复所述NR链路。
示例性地，该多个业务传输速率可以是连续的M业务传输速率。
示例性地，M＝2。
可选地，当所述处理器执行所述指令时，使得所述终端设备还执行以下动作：
在接入所述网络设备为所述终端设备配置的小区之前，发送第二指令，所述第二指令 用于恢复所述NR链路。
可选地，所述第二开关门限大于所述第一开关门限。
这样，通过设置两个开关门限，相比于设置一个开关门限的方式，两个开关门限之间的区间有效地缓和了终端设备不停断开以及恢复NR链路所带来的乒乓效应，提高了通信过程的稳定性；此外，也可以尽可能长时间地保留NR链路，以满足用户对5G通信的体验。
可选地，当所述处理器执行所述指令时，使得所述终端设备还执行以下动作：
在发送所述第一指令之前，确定所述NR链路是否被断开；
在所述NR链路未被断开的情况下，检测所述终端设备的业务传输速率。
这样，在检测终端设备的业务传输速率之前确定NR链路是否被断开，可以避免在NR链路已经被断开的情况下终端设备仍需要检测业务传输速率、以及在确定NR链路需要被断开时终端设备向网络设备发送第一指令而浪费的信令，可以节省信令开销。

为了便于理解，本申请将以具有图2所示结构的终端设备为例，结合附图和应用场景，对本申请实施例提供的无线通信的方法进行具体阐述。
在现有的通信系统中，为了提高数据的传输速率，可以将终端设备同时与多个接入网 设备通信连接，以实现数据的传输，其中，该多个接入网设备可以为支持同一技术的设备，也可以为支持不同技术的设备。在这种通信方法中，以上行为例，需要同时通过该多个接入网设备将数据发送至核心网设备，可以看出，相比于传统的一个终端设备与一个接入网设备通信连接的方式，这种一个终端设备与多个接入网设备通信的方式会不可避免地增加终端设备的功耗。
在目前的通信系统中，终端设备同时与两个接入网设备通信连接的双连接方式的通信最为常见，以下，为了便于描述，以图1所示的通信系统中至少包括一个终端设备和两个接入网设备以及该终端设备可以同时与该两个接入网设备通信连接为例，对本申请实施例进行说明。此外，将该通信系统中的两个接入网设备分别记为第一接入网设备和第二接入网设备，将该终端设备与该第一接入网设备之间的链路记为第一链路，将该终端设备与该第二接入网设备之间的链路记为第二链路。
基于现有技术中终端设备的功耗较多的问题，本申请提供了一种无线通信的方法，在终端设备同时与两个接入网设备通信连接的通信系统中，终端设备可以根据终端设备的实际传输速率确定是否断开其中一个链路(例如，第一链路)，若实际传输速率较小，断开第一链路；若实际传输速率较大，则不断开第一链路，同时采用两条链路进行通信。这种灵活处理终端设备与接入网设备的链路的方法，在不影响速率方面的用户体验的情况下，可以有效地降低终端设备的功耗，提高了功耗方面的用户体验，一定程度上平衡了用户对传输速率和功耗的体验。
应理解，本申请所说的不断开第一链路，表示的是保留或恢复第一链路。本申请所说的保留第一链路，表示的是，在未断开第一链路的情况下，若实际传输速率较大，则对第一链路不做任何处理，继续保留第一链路。本申请所说的恢复第一链路，表示的是，在已经断开第一链路的情况下，若实际传输速率较大，则恢复已经断开的第一链路。
还应理解，本申请所说的终端设备的实际传输速率表示终端设备在开机运行期间的实际速率，可以是终端设备加载各种类型的业务时的实际传输速率。本申请所说的业务可以是各种类型的业务，例如，可以是终端设备操作应用实现的例如浏览网页、视频(高清视频、标准视频)、游戏、阅读、听歌等业务，也可以是终端设备在待机状态下实现的各种业务，例如，通过检测通知消息以通知用户。
示例性地，第一接入网设备和第二接入网设备分别支持不同的技术。可选地，第一接入网设备允许的最大传输速率大于第二接入网设备允许的最大传输速率。
在一种可能的场景中，现有的5G的非独立组网(non-standalone，NSA)实现的就是一种双连接方式的通信。在这种组网中，例如，第一接入网设备支持NR网络，第二接入网设备支持LTE网络，NR网络中允许的最大传输速率大于LTE网络允许的最大传输速率，为了便于描述，将该第一接入网设备可以记为5G接入网设备(或者，也可以记为5G基站)，将终端设备与该5G接入网设备之间的第一链路记为NR链路；同理，将第二接入网设备可以记为4G接入网设备(或者，也可以记为4G基站)，将终端设备与4G接入网设备之间的第二链路记为LTE链路。在NSA网络中可以有两种双连接方式：在第一种方式中，终端设备可以通过4G接入网设备接入NR网络，4G接入网设备作为主基站，5G接入网设备作为辅基站，这种双连接称为LTE NR双连接(LTE NR dual connectivity，ENDC)，在第二种方式中，终端设备可以通过5G接入网设备接入NR网络，5G接入网设 备作为主基站，4G接入网设备作为辅基站，将这种双连接称为NR LTE双连接(NR LTE dual connectivity NEDC)。
在另一种可能的场景中，WLAN(例如，Wi-Fi网络)也可以实现双连接方式的通信。在WLAN中，站点可以与两个接入点通信连接，站点即为终端设备的一例，接入点即为接入网设备的一例。
作为示例而非限定，以下，结合图3至图17，以5G接入网设备和4G接入网设备分别作为接入网设备的两例，对本申请提供的无线通信的方法进行详细说明。
需要说明的是，本申请的LTE可以和4G互换描述，NR可以和5G互换描述。例如，LTE网络可以称为4G网络，LTE链路可以称为4G链路，4G接入网设备可以称为LTE接入网设备。再例如，NR网络可以称为5G网络，NR链路可以称为5G链路，5G接入网设备可以称为NR接入网设备。
首先，对本申请中涉及的与实际传输速率相关的业务传输速率做一说明。
如前所述，本申请可以根据终端设备的实际传输速率确定是否断开或恢复第一链路，可选地，终端设备也可以对实际传输速率做平滑处理，得到处理后的实际传输速率，通过处理后的实际传输速率来确定是否断开或恢复第一链路。这种方式可以使得终端设备的实际传输速率在前后连续时段内不会发生较大的突变，可以避免由于实际传输速率的突变造成终端设备在短时间内不停断开以及恢复第一链路所带来的乒乓效应，以提高通信过程的稳定性。
为了便于描述，在本申请中，将实际传输速率和对实际传输速率进行处理后的速率可以统称为业务传输速率，业务传输速率与实际传输速率相关，下文中统一采用业务传输速率描述实施例。
在一种可能的实现方式中，终端设备可以根据如下公式得到处理后的实际传输速率：

其中，V t1表示终端设备在当前监测周期得到的实际传输速率，V t2表示对实际传输速率进行平滑处理后的速率，V l表示终端设备在当前监测周期的前一个监测周期得到的平滑处理后的速率，

表示平滑因子，取值范围为[0.1,1]，示例性地，当实际传输速率降低时，
Figure PCTCN2020127418-appb-000003
的取值可以小于0.5，当实际传输速率增加时，
Figure PCTCN2020127418-appb-000004
的取值可以大于或等于0.5。
图3所示为本申请提供的无线通信的方法300的示意性流程图，图4和图6所示为本申请提供的无线通信的方法300的部分示意性流程图。图5所示为本申请提供的开关门限的示意图。下面，结合图3至图6，对本申请的方法300进行详细说明。
S310、终端设备注册NSA网络。
在该步骤中，终端设备与4G接入网设备建立LTE链路以及与5G接入网设备建立NR链路，实现NAS网络的注册。应理解，终端设备可以在开机后直接完成LTE链路和NR链路的连接，也可以是在开机后先完成LTE链路一段时间后再完成NR链路的连接，本申请不作任何限定，终端设备可以是在开机运行后的任意时段完成LTE链路和NR链路的连接。
在终端设备注册完NAS网络后，用户可以操作终端设备传输业务的相关数据，实现业务诉求。
在NAS网络中，终端设备同时采用NR链路和LTE链路进行通信。以上行传输为例， 具体地，终端设备可以将待发送的上行数据中的一部分数据通过LTE链路发送给4G接入网设备，将该上行数据中的另一部分数据通过NR链路发送给5G接入网设备，假设，5G接入网设备与核心网设备通信连接，4G接入网设备将从终端设备接收到的一部分数据发送给5G接入网设备，5G接入网设备对整个上行数据进行处理，发送至核心网设备，以完成上行数据的传输过程。业务的下行数据的传输过程以上行数据的传输类似，核心网设备将待发送的下行数据发送至5G接入网设备，5G接入网设备可以将该下行数据的一部分数据发送至4G接入网设备，4G接入网设备向终端设备发送该一部分数据以及5G接入网设备向终端设备发送剩余的数据，以将完整的下行数据发送至终端设备，完成下行数据的传输过程。
此外，为了便于获得业务传输速率，在终端设备的运行期间可以时时监控终端设备的业务传输速率，设置监测周期，周期性得到业务传输速率，即，获得每个监测周期内的业务传输速率。例如，一个监测周期的时长是2s，终端设备时时监控业务传输速率，每2s获取一个业务传输速率。
为了便于描述，将一个监测周期内的业务传输速率简记为一个业务传输速率，多个监测周期内的业务传输速率简记为多个业务传输速率。
示例性地，以一个业务传输速率为例，一个业务传输速率可以是终端设备在一个监测周期内的平均传输速率，也可以是终端设备在一个监测周期内的业务传输速率的最高值或最低值，也可以是终端设备在一个监测周期的结束时刻的业务传输速率，本申请不做任何限定。
S321、终端设备确定NR链路是否被断开。
考虑到可能存在由于异常原因(例如，信号强度太差)导致NR链路已经被强行断开的情况，可选地，在S321中，终端设备确定NR链路是否被断开。若NR链路未被断开，则表示终端设备处于NAS网络中，可执行S322。若NR链路被断开，则不执行S322，继续采用LTE链路进行通信，并且，可以执行S331，以确定是否恢复NR链路，在确定可以恢复NR链路的情况下，通过和接入网设备之间的交互完成NR链路的恢复。
这样，通过该步骤，可以避免在NR链路已经被断开的情况下终端设备仍需要确定是否断开NR链路以及在确定NR链路需要被断开时终端设备向5G接入网设备发送第一指令而浪费的信令，可以节省信令开销。
应理解，终端设备也可以不需要执行S321，可以直接执行S322，只不过会浪费信令而已。
实现中，该步骤可由终端设备的处理器(如图2所示的终端设备的处理器210)和移动通信模块(如图2所示的终端设备的移动通信模块250)执行。示例性地，移动通信模块可以向处理器发送信令以指示NR链路是否被断开，处理器根据该信令确定NR链路是否被断开。
S322、终端设备确定是否断开NR链路。
终端设备监控业务传输速率，获得每个监测周期内的业务传输速率。终端设备可以设置开关门限，将业务传输速率与开关门限进行比较以确定是否断开NR链路。为了便于描述，将用于确定是否断开NR链路的开关门限记为第一开关门限。
可选地，若终端设备的N个业务传输速率小于第一开关门限，则终端设备确定断开 NR链路，采用LTE链路进行通信，可执行S323，其中，N为大于或等于1的整数。对应地，可以规定，若终端设备的N个业务传输速率中的至少一个业务传输速率大于或等于该第一开关门限，则终端设备确定不断开NR链路，保留NR链路，保持当前的链路状态，继续采用NR链路和LTE链路进行通信。此外，关于N个业务传输速率与第一开关门限相同的情况，可以设置为确定断开NR链路的条件，或者，也可以设置为确定不断开NR链路的条件，具体可以视实际情况而定，本申请不做任何限定。
应理解，N个业务传输速率表示N个监测周期内的业务传输速率。
需要说明的是，当终端设备加载业务时，该N个业务传输速率可以是针对相同业务的业务传输速率，也可以是针对不同业务的业务传输速率，本申请不做任何限定。例如，N为5，5个监测周期内的业务传输速率都是针对视频的业务传输速率；再例如，N为5，前4个监测周期内的业务传输速率都是针对浏览网页的业务传输速率，第5个监测周期内的业务传输速率是针对高清视频的业务传输速率。
在该步骤中，可以根据N的大小，从以下两种情况对实施例做进一步说明。
情况A1(N＝1)
在该情况中，N＝1，该N个业务传输速率中表示一个业务传输速率，该N个业务传输速率中的至少一个业务传输速率就仅表示一个业务传输速率。也就是说，若1个业务传输速率小于第一开关门限，则终端设备确定断开NR链路，采用LTE链路进行通信。若1个业务传输速率大于或等于该第一开关门限，则终端设备确定不断开NR链路，保留NR链路，保持当前的链路状态，即，继续采用NR链路和LTE链路进行通信。
在S322中，终端设备检测业务传输速率，只要检测到某个监测周期的业务传输速率小于第一开关门限，则确定断开NR链路。只要检测到某个监测周期的业务传输速率大于或等于第一开关门限，则确定保留NR链路。
情况A2(N＞1)
在该情况中，N是大于1的整数，示例性地，N可以是2、3、4、5等，该N个业务传输速率中的至少一个业务传输速率表示一个或多个业务传输速率，也可以表示该N个业务传输速率中的部分或全部业务传输速率。
可选地，该N个业务传输速率可以是连续的N个业务传输速率。也就是说，若连续的N个业务传输速率小于第一开关门限，则终端设备确定断开NR链路，采用LTE链路进行通信。反过来说，若连续的N个业务传输速率中的至少一个业务传输速率大于或等于该第一开关门限，则终端设备确定不断开NR链路，保留NR链路，保持当前的链路状态，继续采用NR链路和LTE链路进行通信。可以理解，连续的N个业务传输速率即表示在连续的N个监测周期内的业务传输速率，例如，N为5，连续的N个业务传输速率可以理解为从第1个监测周期持续到第5个监测周期内的业务传输速率。
在S322中，终端设备检测业务传输速率，检测到连续的N个监测周期内的N个业务传输速率小于第一开关门限，才确定断开NR链路；否则，若不满足上述条件，则确定保留NR链路。
在一些可能的实施例中，终端设备的业务传输速率可以基于当前终端设备运行的前台业务或者后台业务的传输速率。
下面，结合图3，对S322做详细说明。
示例性地，可以设置定时器M，定时器M的时长等于监测周期的时长与N的乘积。
在S3221中，启动定时器M。
在S3222中，在定时器M的时长内，确定是否断开NR链路。具体地，从定时器M的起始时间计时，若连续的N个监测周期内的N个业务传输速率都小于第一开关门限，则终端设备确定可以断开NR链路，执行S323；若在定时器M的时长内存在至少一个业务传输速率大于或等于第一开关门限，则重新执行S3221和S3222，启动定时器M以及在定时器M的时长内继续确定是否断开NR链路，如此反复执行，直到满足连续的N个业务传输速率小于第一开关门限，则执行S323。
假设，N＝5，监测周期为1s，定时器M的时长为5s。例如，从定时器M的起始时间开始计时，从0开始计数，第1-5个业务传输速率都小于第一开关门限，则终端设备确定断开NR链路。再例如，从定时器M的起始时间开始计时，从0开始计数，第1-4个业务传输速率都小于第一开关门限，第5个业务传输速率大于第一开关门限，则终端设备重新启动定时器M，继续确定是否断开NR链路。
作为示例而非限定，该N个业务传输速率也可以是非连续的N个业务传输速率。可以理解，非连续的N个业务传输速率即表示在非连续的N个监测周期内的业务传输速率，例如，N＝5，非连续的N个业务传输速率可以理解为第1个监测周期、第3个监测周期、第5个监测周期、第7个监测周期以及第9个监测周期内的业务传输速率。
应理解，S321和S322的执行顺序可以互换，本申请不作任何限定。
实现中，该步骤可由终端设备的处理器执行。
S323、终端设备发送第一指令。
若在S322中终端设备确定断开NR链路，则终端设备可以发送第一指令，该第一指令用于指示5G接入网设备释放NR链路。
在一种可能的实现方式中，终端设备可以向4G接入网设备发送第一指令，4G接入网设备将该第一指令发送给5G接入网设备，5G接入网设备根据该第一指令释放NR链路。
示例性地，该第一指令可以是辅小区组(secondary cell group，SCG)失败信息(SCG failure information)。
在另一种可能的实现方式中，终端设备可以向5G接入网设备发送该第一指令，5G接入网设备根据该第一指令释放NR链路。
可选地，5G接入网设备可以通过4G接入网设备向终端设备发送信令，该信令用于告知终端设备NR链路已经被断开。
在该步骤中，NR链路被断开，后续，终端设备采用LTE链路进行通信。
实现中，该步骤可由终端设备的处理器和移动通信模块执行。示例性地，处理器在确定需要断开NR链路后，向移动通信模块发送该第一指令，该移动通信模块向5G接入网设备发送该第一指令。
S331、终端设备确定是否恢复NR链路。
终端设备继续检测业务传输速率，获得每个监测周期的业务传输速率，根据业务传输速率与开关门限确定是否恢复NR链路。为了便于描述，将用于确定是否恢复NR链路的开关门限记为第二开关门限。
可选地，若终端设备的M个业务传输速率大于第二开关门限，则终端设备确定恢复 NR链路，采用LTE链路和NR链路进行通信，可执行S332，其中，M为大于或等于1的整数。对应地，可以规定，若M个业务传输速率中至少一个业务传输速率大于或等于该第二开关门限，则终端设备确定不恢复NR链路，保持当前的链路状态，继续使用LTE链路进行通信。此外，关于M个业务传输速率与第二开关门限相同的情况，可以设置为确定恢复NR链路的条件，或者，也可以设置为确定不恢复NR链路的条件，具体可以视实际情况而定，本申请不做任何限定。
其中，M与N可以相同，也可以不同，M个业务传输速率的具体描述可以参考上文关于N个业务传输速率的相关描述，此处不再赘述。
可选地，N大于M。例如，M为2，N为5。
这样，通过设置用于确定是否断开NR链路的业务传输速率的数量N大于用于确定是否恢复NR链路的业务传输速率的数量M，在可以节省功耗的同时，可以尽可能使得终端设备处于NR网络中，满足用户对5G通信的体验。
此外，第二开关门限与第一开关门限可以相同，也可以不同，本申请不作任何限定。其中，在第二开关门限与第一开关门限不同的情况中，第二开关门限大于第一开关门限。
参考图6，横坐标表示业务传输速率，从左至右业务传输速率逐渐变大。在同时存在NR链路和LTE链路的情况中，若N个业务传输速率小于第一开关门限(位于第一开关门限的左边)，则确定断开NR链路，若N个业务传输速率中的至少一个业务传输速率大于或等于第一开关门限(位于第一开关门限的右边)，则确定不断开NR链路，保持当前的链路状态，即，采用LTE链路和NR链路进行通信。在仅存在LTE链路的情况中，若M个业务传输速率大于第二开关门限(位于第二开关门限的右边)，则确定恢复NR链路，若M个业务传输速率中的至少一个业务传输速率小于或等于第二开关门限(位于第二开关门限的左边)，则确定不恢复NR链路，保持当前的链路状态，即，采用LTE链路进行通信。可以明显看出，因为设置了两个开关门限，相比于设置一个开关门限的方式，两个开关门限之间的区间有效地缓和了终端设备不停断开以及恢复NR链路所带来的乒乓效应，提高了通信过程的稳定性；此外，也可以尽可能长时间地保留NR链路，以满足用户对5G通信的体验。
在该步骤中，可以根据M的大小，从以下两种情况对实施例做进一步说明。
情况B1(M＝1)
在该情况中，M＝1，该M个业务传输速率中表示一个业务传输速率，该M个业务传输速率中的至少一个业务传输速率就仅表示一个业务传输速率。也就是说，若1个业务传输速率大于第二开关门限，则终端设备确定恢复NR链路，采用LTE链路和NR链路进行通信。若1个业务传输速率小于或等于该第二开关门限，则终端设备确定不恢复NR链路，保持当前的链路状态，继续采用LTE链路进行通信。
在S331中，终端设备检测业务传输速率，只要检测到某个监测周期的业务传输速率大于第二开关门限，则恢复NR链路。只要检测到某个监测周期的业务传输速率小于或等于第二开关门限，则不恢复NR链路，保持当前的链路状态，继续采用LTE链路进行通信。
情况B2(M＞1)
在该情况中，M是大于1的整数，示例性地，M可以是2、3、4等整数，该M个业务传输速率中的至少一个业务传输速率表示一个或多个业务传输速率，也可以表示该M 个业务传输速率中的部分或全部业务传输速率。
可选地，该M个业务传输速率可以是连续的M个业务传输速率。也就是说，若连续的M个业务传输速率大于第二开关门限，则终端设备确定恢复NR链路，采用LTE链路和NR链路进行通信。反过来说，若连续的M个业务传输速率中的至少一个业务传输速率小于或等于该第二开关门限，则终端设备确定不恢复NR链路，保持当前的链路状态，继续采用LTE链路进行通信。可以理解，连续的M个业务传输速率即表示在连续的M个监测周期内的业务传输速率，例如，M为2，连续的M个业务传输速率可以理解为从第1个监测周期持续到第2个监测周期内的业务传输速率。
在S331中，终端设备监测业务传输速率，监测到连续的M个监测周期内的M个业务传输速率大于第二开关门限，才确定恢复NR链路；否则，若不满足上述条件，则确定不恢复NR链路，继续采用LTE链路进行通信。
下面，结合图6，对S331做详细说明。
示例性地，可以设置定时器N，定时器N的时长等于监测周期的时长与M的乘积。
在S3311中，启动定时器N。
在S3312中，在定时器N的时长内，确定是否恢复NR链路。具体地，从定时器N的起始时间开始，若连续的M个监测周期内的M个业务传输速率都大于第二开关门限，则终端设备确定可以恢复NR链路，执行S332；若在定时器N的时长内存在至少一个业务传输速率小于第二开关门限，则重新执行S3311和S3312，启动定时器N以及在定时器N的时长内继续确定是否恢复NR链路，如此反复执行，直到满足连续的M个业务传输速率大于第二开关门限，则执行S332。
假设，M＝2，监测周期为1s，定时器N的时长为2s。例如，从定时器N的起始时间开始计时，从0开始计数，第1-2个业务传输速率都大于第二开关门限，则终端设备确定恢复NR链路。再例如，从定时器N的起始时间开始计时，从0开始计数，第1个业务传输速率都大于第二开关门限，第2个业务传输速率小于第二开关门限，则终端设备确定不恢复NR链路，继续采用LTE链路进行通信，并且，终端设备重新启动定时器N，继续确定是否恢复NR链路。
作为示例而非限定，该M个业务传输速率也可以是非连续的M个业务传输速率。可以理解，非连续的M个业务传输速率即表示在非连续的M个监测周期内的业务传输速率，例如，M＝2，非连续的M个业务传输速率可以理解为第1个监测周期和第3个监测周期内的业务传输速率。
实现中，该步骤可由终端设备的处理器执行。
S332、终端设备恢复NR链路。
在该步骤中，可以有两种方式恢复NR链路，下面，分别做详细说明。
在一种可能的实现方式中，4G接入网设备周期性地发送信令以指示终端设备测量多个5G小区以建立NR链路，例如，该信令可以是RRC连接重配置(RRC connection reconfiguration)信息，该RRC连接重配置信息用于配置终端设备需要测量的5G小区，也可以记为测量配置(measure configuration)。若终端设备确定不需要恢复NR链路，则不需要基于该信令进行5G小区的测量。若终端设备确定需要恢复NR链路，则可以根据该信令测量该多个5G小区，向4G接入网设备上报满足条件的5G小区的测量报告 (measurement report)，该条件可以是例如被测量小区的信号强度满足要求等，4G接入网设备将满足条件的5G小区的测量报告发送给5G接入网设备，5G接入网设备根据该测量报告为终端设备配置小区，通过4G接入网设备向终端设备发送小区配置信息，例如，该小区配置信息可以是RRC连接重配置(RRC connection reconfiguration)信息，该RRC连接重配置信息用于配置终端设备接入的小区，也可以记为SCG配置(SCG configuration)，终端设备根据该小区配置信息接入5G接入网设备为其配置的小区，完成NR链路的建立。
在另一种可能的实现方式中，4G接入网设备周期性地发送信令以指示终端设备测量多个5G小区以建立NR链路，若终端设备确定不需要恢复NR链路，则不需要基于该信令进行5G小区的测量，若终端设备确定需要恢复NR链路，终端设备向4G接入网设备发送第二指令，该第二指令用于指示5G接入网设备恢复NR链路。4G接入网设备向5G接入网设备转发该第二指令，并且，4G接入网设备开始向终端设备发送信令以指示终端设备测量多个5G小区以恢复NR链路，后续的具体步骤与第一种可能的实现方式相同，不再赘述。
实现中，该步骤可由终端设备的处理器和移动通信模块执行。示例性地，处理器在确定需要恢复NR链路后，通过移动通信模块与4G接入网设备和5G接入网设备进行信息交互，以恢复NR链路。
在恢复NR链路后，终端设备继续检测业务传输速率，执行S321以确定是否断开NR链路，如此反复循环，在不影响用户对业务传输速率的体验的情况下，实现NR链路的断开和恢复。
应理解，上述方法300中各过程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，S321和S322可以的执行顺序可以互换。
还应理解，上述方法300中的各个步骤的过程仅为示意性说明，实现中，可以基于实际情况执行上述部分或全部步骤的功能和内在逻辑。例如，方法300可以包括步骤S310、S322、S323、S331和S332。
下面，示例性地，对本申请确定第一开关门限和第二开关门限的两种方式进行说明。
方式1
可选地，终端设备根据终端设备所处的LTE网络中的信号强度、小区带宽、双工模式以及传输模式中的至少一个参数确定第一开关门限和第二开关门限。
小区带宽表示终端设备所在的小区占用的带宽。例如，小区带宽可以是20MHz、60MHz等。
双工模式包括时分双工模式(time-division duplex，TDD)或频分双工模式(frequency-division duplex，FDD)。
传输模式包括上行传输或下行传输。
在一种可能的实现方式中，终端设备可以根据终端设备所处的LTE网络中的信号强度、小区带宽、双工模式以及传输模式中的至少一个参数确定速率门限，根据速率门限确定保护速率，根据速率门限和保护速率确定第一开关门限和第二开关门限。
示例性地，保护速率是根据速率门限得到。作为示例而非限定，保护速率可以是速率 门限的x倍，例如，x可以是0.1。
在第一开关门限和第二开关门限不同的情况下，继续参考图3，可选地，第一开关门限＝速率门限-保护速率，第二开关门限＝速率门限+保护速率。
在第一开关门限和第二开关门限相同的情况下，用于确定是否断开或恢复NR链路的开关门限可以视为一个开关门限，示例性地，可以将得到的速率门限作为该开关门限，不需要保护速率。
表1至表4所示为本申请所示的速率门限与LTE网络中的信号强度、小区带宽、双工模式以及传输模式之间的关系。可以看出，信号强度、小区带宽、双工模式以及传输模式中任一个发生变化，都会影响速率门限，以影响开关门限。
为了能够使得终端设备确定较为合适的开关门限，在一种可能的实现方式中，当上述任一个参数发生变化时，终端设备可以基于变化的参数重新计算开关门限。在另一种可能的实现方式中，当终端设备所处的小区发生变化时，终端设备可以重新获得终端设备在当前小区的上述4个参数，确定新的开关门限，应理解，在终端设备所处的小区发生变化时，上述任一个参数可以发生变化，也可以不发生变化。

下面，结合表5，以信号强度发生变化导致的第一开关门限发生变化为例，对终端设备断开NR链路的过程做一简单说明。其他因素导致的第一开关门限和第二开关门限的变化与之类似，不再举例说明。
如表5所示，用户操作终端设备加载游戏业务，信号强度较好(10dB)时，第一开关门限较大(11Mbps)，大于终端设备的业务传输速率(11Mbps)，断开NR链路，采用LTE链路进行通信；随后，终端设备被移动到信号强度不好的地方，信号强度为2dB，很明显，第一开关门限降低，变为4Mbps，小于终端设备的业务传输速率，恢复NR链路，采用LTE链路和NR链路进行通信。

方式2
可选地，第一开关门限和第二开关门限可以是预定义的。
在一种可能的实现方式中，在第一开关门限和第二开关门限不同的情况下，可以根据业务传输速率将应用程序(后续简称为应用)分为多类应用，任意两种类型的应用加载的业务的业务传输速率不同，每种类型的应用包括至少一个应用，每种类型的应用对应每组开关门限，每组开关门限包括一个第一开关门限和一个第二开关门限，任意两组开关门限中的开关门限不完全相同，也就是说，任意两组开关门限中可以有一个开关门限相同，也可以完全不同。
示例性地，应用被分为两类应用，分别是应用类型A和应用类型B，应用类型A对应开关门限组A，应用类型B对应开关门限组B，应用类型A中的应用的业务传输速率大于应用类型B中的应用的业务传输速率，对应地，开关门限组A中的第一开关门限大于或等于开关门限组B中的第一开关门限，开关门限组A中的第二开关门限大于开关门限组B中的第二开关门限，或者，开关门限组A中的第一开关门限大于开关门限组B中的第一开关门限，开关门限组A中的第二开关门限大于或等于开关门限组B中的第二开关门限。
应理解，本申请所说的应用的业务传输速率可以理解为应用加载业务的业务传输速率。
示例性地，实现中，可以为每个应用配置一组开关门限，属于同一类应用的应用对应的开关门限相同。终端设备可以根据当前在前台运行(或者，被用户正在操作)的应用确定该应用对应的一组开关门限，参考S310-S332描述的实施例，根据该应用的业务传输速率和对应的一组开关门限确定是否断开或恢复NR链路。
在另一种可能的实现方式中，在第一开关门限和第二开关门限相同的情况下，可以根据业务传输速率将应用分为多类应用，任意两种类型的应用的业务传输速率不同，每种类型的应用包括至少一个应用，每种类型的应用对应一个开关门限，任意两个开关门限不相同。
示例性地，可以将应用分为两类应用，分别是应用类型A和应用类型B，应用类型A对应开关门限A，应用类型B对应开关门限B，应用类型A中的应用的业务传输速率大于应用类型B中的应用的业务传输速率，对应地，开关门限A大于开关门限B。
示例性地，实现中，可以为每个应用配置一个开关门限，属于同一类应用的应用对应的开关门限相同。终端设备可以根据在前台运行的应用，确定该应用对应的开关门限，参考S310至S332描述的实施例，根据该应用的业务传输速率和对应的开关门限确定是否断开或恢复NR链路。
示例性地，应用类型A可以包括如下应用：导航类应用(例如，高德地图、百度地图等)、阅读类应用(例如，微信读书)和游戏类应用(例如，王者荣耀、QQ游戏等)。应用类型B可以包括如下应用：可内嵌视频的应用(例如，微信、微博、浏览器等)和视频类应用(例如，优酷视频、腾讯视频等)。
以上，结合图3至图6对本申请提供的无线通信的方法300做了详细说明。本申请还提供了另一种无线通信的方法400，以下，对方法400做说明。
与方法300的主要区别在于，方法300不区分应用，可以监控终端设备上任何应用的业务传输速率，以根据终端设备的业务传输速率确定是否断开或恢复NR链路。而在方法400中，可以不用对所有应用进行监控，而是可以根据业务传输速率将应用分类，一类应用是需要终端设备监控的应用，需要检测应用的业务传输速率来断开或恢复NR链路，一般情况下，可以将业务传输速率较低的应用归类于该类应用，为了便于描述，将该类应用记为预设类应用，该预设类应用中包括一个或多个预设应用；另一类应用是不需要终端设备监控的应用，不需要检测应用的业务传输速率，一般情况下，可以将业务传输速率较高的应用归类于该类应用，为了便于描述，将该类应用记为非预设类应用，该非预设类应用包括一个或多个非预设应用。
示例性地，预设类应用中的应用的业务传输速率小于非预设应用中的应用的业务传输速率。
例如，预设应用的业务传输速率较小于第一阈值，非预设应用的业务传输速率大于第一阈值。
针对预设类应用，终端设备监控该预设类应用中的应用，以根据应用的业务传输速率确定是否断开或恢复NR链路，以在尽可能满足用户体验的同时，减少终端设备的功耗。针对非预设类应用，终端设备可以不监控非预设类应用中的应用，即，终端设备可以不需要检测业务传输速率，也不需要对NR链路做任何处理，而是一直采用LTE链路和NR链路进行通信，以尽可能优先保证用户对非预设类应用中的应用的速率需求，不影响用户对5G通信的体验。
可选地，预设类应用可以包括如下应用：导航类应用、阅读类应用、游戏类应用、可内嵌视频的应用。
可选地，非预设类应用可以包括如下应用：用于下载软件的应用市场、用于测试终端 设备性能的测试软件(例如，speedtest应用)、视频类应用。
应理解，上述对预设类应用和非预设类应用的分类仅为示意性说明，不应对本申请构成限定。上述举例的各种类型的应用可以基于实际情况自由组合分类。作为示例而非限定，也可以将可内嵌视频的应用归类于非预设类应用中。
在该实施例中，同样设置开关门限，将应用的业务传输速率与开关门限进行比较以确定是否断开或恢复链路。同方法300的描述，将用于确定是否断开NR链路的开关门限记为第一开关门限，将用于确定是否恢复NR链路的开关门限记为第二开关门限，第一开关门限和第二开关门限可以相同，也可以不同。
在该方法中，示例性地，确定第一开关门限和第二开关门限的方式可以参考方法300中的方式1和方式2，此处不再赘述。
需要说明的是，在方法400中采用上述方式2确定开关门限时，是对属于预设类应用中的应用进行分类。
示例性地，在预设类应用可以包括导航类应用、阅读类应用、游戏类应用、可内嵌视频的应用的情况下，可选地，预设类应用可以被分为三类，应用类型A可以包括如下应用：导航类应用、阅读类应用，应用类型B可以包括游戏类应用，应用类型C可以包括可内嵌视频的应用。可选地，应用类型A对应的一组开关门限可以是：第一开关门限为1Mbps，第二开关门限为3Mbps，应用类型B对应的一组开关门限可以是：第一开关门限为1Mbps，第二开关门限为5Mbps，应用类型C对应的一组开关门限可以是：第一开关门限为2Mbps，第二开关门限为20Mbps。
示例性地，在预设类应用可以包括导航类应用、阅读类应用和游戏类应用的情况下，可选地，预设类应用可以被分为两类，应用类型A可以包括如下应用：导航类应用、阅读类应用，应用类型B可以包括游戏类应用。可选地，应用类型A对应的一组开关门限可以是：第一开关门限为1Mbps，第二开关门限为3Mbps，应用类型B对应的一组开关门限可以是：第一开关门限为1Mbps，第二开关门限为5Mbps。
在应用运行过程中，为满足不同阶段的需求，可以设置各种定时器。示例性地，设置第一定时器，记为定时器A，在应用被打开时，可以启动定时器A，以避免终端设备在短时间内频繁恢复和断开NR链路，以避免乒乓效应。示例性地，设置第三定时器，记为定时器M，可以对应方法300中步骤S322中的定时器M，可以根据定时器M确定是否断开NR链路。示例性地，设置第四定时器，记为定时器N，可以对应方法300中步骤S331中的定时器N，可以根据定时器N确定是否恢复NR链路。示例性地，设置第二定时器，记为定时器B，在NR链路被恢复后，可以启动定时器B，使得终端设备在定时器B的时长内保留NR链路，以尽可能提高用户对5G通信的体验，也能避免终端设备在短时间内频繁恢复和断开NR链路，以避免乒乓效应。
应理解，上述各个定时器的时长可以根据实际情况不定期调整，本申请不作任何限定。
可选地，定时器A的时长为30s。
可选地，定时器M的时长为3s。
可选地，定时器N的时长为3s。
可选地，定时器B的时长为30s。
下面，结合图7和图8，对本申请提供的另一无线通信的方法400做详细说明。图7 所示为本申请提供的无线通信的方法400的示意性流程图，图8所示为本申请提供的无线通信的方法400的另一示意性流程图。
S411、终端设备打开第一应用，清空定时器。
终端设备监控在前台运行的应用，监测到前台的应用发生变化，用户打开了新的应用，终端设备可以清空所有为监控应用设置的定时器，将定时器的数据清零，以便于为打开的新的应用重新计时，便于后续较为准确地实现NR链路的断开或恢复。为了便于描述，将当前在前台运行的应用记为第一应用。应理解，在前台运行的应用表示的是用户当前正在操作的可以看到显示界面的应用。
应理解，该步骤是可选的步骤，在第一应用被打开时，也可以不需要清空定时器，执行S412。
实现中，该步骤可由终端设备的处理器执行。
S412、终端设备确定该第一应用是否为预设类应用。
在该方法中，由于可以仅需要对属于预设类应用中的应用监控以确定是否断开或恢复NR链路，因此，在第一应用被打开运行后，在S412中，可以进一步确定该第一应用是否为预设类应用中的预设应用。示例性地，终端设备可以通过第一应用的应用标识确定该第一应用是否为预设应用，例如，应用标识可以是应用程序接口(application programming interface，API)、应用程序名称以及应用程序的身份标识(identity，ID)等标识。
若该第一应用是该预设应用，则执行S413，目的是后续可以确定是否断开NR链路。
若该第一应用是非预设应用(即，第一应用不是预设应用)，可选地，终端设备可以不需要监控该第一应用以断开NR链路，可以采用LTE链路和NR链路进行通信，因此，终端设备可以执行S414，确定NR链路是否被断开，主要是考虑到用户在操作该第一应用之前的应用时，NR链路可能被断开的情况。若终端设备确定NR链路被断开，则执行S415以恢复NR链路，其中，关于恢复NR链路的具体描述可以参考方法300的S332的相关描述，此处不再赘述。若终端设备确定NR链路未被断开，则执行S416，保持当前的链路状态，采用LTE链路和NR链路进行通信。当然，若该第一应用是非预设应用，也可以不用执行S414，无论NR链路是否被断开，保持当前的链路状态也是可以的。
在该步骤中，终端设备不仅可以确定第一应用是否为预设应用，为了避免在用户操作该第一应用的过程中断开NR链路会影响其他业务的正常运行，终端设备还可以进一步确定该终端设备是否处于优先模式中，无论该第一应用是否为预设应用，只要该终端设备处于优先模式中，则不执行S413，执行S414。示例性地，优先模式可以包括如下少一种模式：通话模式、充电模式、性能优化模式、热点共享模式，其中，通话模式表示终端设备处于处理通话业务的状态，充电模式表示终端设备处于被充电的状态，性能优化模式表示终端设备被设置在能够让终端设备处于性能最优的状态，这种性能最优的状态可以包括网络的传输速率较高的状态，热点共享模式表示终端设备处于将移动数据的流量分享给其他设备使用的模式。
若第一应用为预设应用，在终端设备处于通话模式时，终端设备不监控业务传输速率以对NR链路处理，可以避免由于频繁断开和恢复NR链路造成的乒乓效应而影响通话质量。
若第一应用为预设应用，在终端设备处于充电模式时，终端设备不监控业务传输速率 以对NR链路处理，由于当前的充电模式可以为终端设备提供足够功耗，采用LTE链路和NR链路进行通信，可以提高传输效率。
若第一应用为预设应用，在终端设备处于性能优化模式和/或热点共享模式时，终端设备不监控业务传输速率以对NR链路处理，可以保证性能优化模式，优先满足用户需求以提高传输效率。
若第一应用为预设应用，在终端设备处于热点共享模式时，终端设备不监控业务传输速率以对NR链路处理，可以满足多个设备对传输速率的需求。
结合预设应用和优先模式，终端设备确定该第一应用是否为预设应用以及确定该终端设备是否处于优先模式中，若终端设备确定该第一应用为预设应用且终端设备不处于优先模式，则执行S413，否则，执行S414或保持当前的链路状态。
应理解，步骤S411和S412可以同时进行，也可以先执行S411再执行S412，本申请不作任何限定。
实现中，该步骤可由终端设备的处理器执行。
S413、终端设备确定NR链路是否被断开。
考虑到终端设备在操作第一应用之前的应用的过程中已经断开了NR链路的情况，以及，由于异常原因(例如，信号强度太差)导致的NR链路已经被强行断开的情况，可选地，在终端设备确定第一应用为预设应用后，在S413中，终端设备确定NR链路是否被断开。若NR链路未被断开，则表示终端设备处于NAS网络中，可执行S414或S421。若NR链路被断开，则不执行S414或S421，继续采用LTE链路进行通信，并且，可以执行S431，以确定是否恢复NR链路，在确定可以恢复NR链路的情况下，通过和接入网设备之间的交互完成NR链路的恢复。
这样，通过该步骤，可以避免在NR链路已经被断开的情况下终端设备仍需要确定是否断开NR链路以及在确定NR链路需要被断开时终端设备向5G接入网设备发送第一指令而浪费的信令，可以节省信令开销。
应理解，终端设备也可以不需要执行S413，可以直接执行S414或S421，只不过会浪费信令而已。
实现中，该步骤可由终端设备的处理器和移动通信模块执行。示例性地，移动通信模块可以向处理器发送信令以指示NR链路是否被断开，处理器根据该信令确定NR链路是否被断开。
S417、终端设备启动定时器A。
终端设备认为可以进一步确定是否断开NR链路，在确定是否断开NR链路之前，可选地，终端设备执行S417，启动定时器A，在该定时器A的时长内，终端设备继续采用当前状态的链路进行通信，对NR链路不做任何判断处理，目的是避免由于用户在切换应用前后的短时间内恢复和断开NR链路造成的乒乓效应。
其中，当前状态的链路表示第一应用被打开后的链路。例如，第一应用被打开时，NR链路已经被断开，终端设备继续使用LTE链路进行通信，一般来说，这种情况多数存在于终端设备在操作第一应用之前的应用的过程中已经断开了NR链路的情况中，也存在于由于异常原因(例如，信号强度太差)导致的NR链路已经被强行断开的情况中。再例如，第一应用被打开时，NR链路未被断开，继续使用LTE链路和NR链路进行通信，一般来 说，这种情况多数存在于终端设备在操作第一应用之前的应用的过程中并未断开NR链路的情况中。
应理解，步骤S413和S417的顺序可以互换，可以先执行S413再执行S417，也可以先执行S417再执行S413，本申请不作任何限定。
实现中，该步骤可由终端设备的处理器执行。
S421、终端设备确定是否断开NR链路。
同方法300，终端设备可以设置开关门限，将第一应用的业务传输速率与对应的开关门限进行比较以确定是否断开NR链路，为了便于描述，将用于确定是否断开NR链路的开关门限也记为第一开关门限。若预设类应用被分为多类，第一应用属于预设类应用中的一类应用，如方法300所述，可以为每个应用配置对应的开关门限(例如，第一开关门限和第二开关门限)，一类应用对应的开关门限相同。针对该第一应用，终端设备可以根据该第一应用确定对应的第一开关门限，根据该第一应用的业务传输速率和对应的第一开关门限确定是否断开NR链路。
可选地，若N个业务传输速率小于第一开关门限，则终端设备确定断开NR链路，采用LTE链路进行通信，可执行S421，其中，N为大于或等于1的整数。对应地，可以规定，若N个业务传输速率中的至少一个业务传输速率大于或等于该第一开关门限，则终端设备确定不断开NR链路，保留NR链路，保持当前的链路状态，继续采用NR链路和LTE链路进行通信。此外，关于N个业务传输速率与第一开关门限相同的情况，可以设置为确定断开NR链路的条件，或者，也可以设置为确定不断开NR链路的条件，具体可以视实际情况而定，本申请不做任何限定。
其中，关于N个业务传输速率的具体描述可以参考方法300中步骤S322的相关描述，不再赘述。
在该步骤中，根据N的大小，从N＝1以及N＞1的两种情况对实施例的进一步说明可以参考方法300中步骤S322中的情况A1和情况A2，此处不再赘述。
其中，在N＞1的情况中，终端设备可以根据定时器M确定是否断开NR链路，具体描述可以参考S322的S3221和S3222，不再赘述。应理解，终端设备执行开启定时器M的动作可以在S414中定时器A的时长结束后执行，也可以在不包括S413和S417的实施例中在S412之后执行，也可以在不包括S417的实施例中在S413之后执行，本申请不作任何限定。
实现中，该步骤可由终端设备的处理器执行。
S422、终端设备发送第一指令。
关于该步骤的具体描述可以参考方法300中步骤S323的相关描述，不再赘述。
S431、终端设备确定是否恢复NR链路。
在S422之后，终端设备继续检测第一应用务的业务传输速率，获得每个监测周期的业务传输速率，根据业务传输速率与开关门限确定是否恢复NR链路。为了便于描述，将用于确定是否恢复NR链路的开关门限也记为第二开关门限。
可选地，若M个业务传输速率大于第二开关门限，则终端设备确定恢复NR链路，采用LTE链路和NR链路进行通信，可执行S432，其中，M为大于或等于1的整数。对应地，可以规定，若M个业务传输速率中至少一个业务传输速率大于或等于该第二开关 门限，则终端设备确定不恢复NR链路，保持当前的链路状态，继续使用LTE链路进行通信。此外，关于M个业务传输速率与第二开关门限相同的情况，可以设置为确定恢复NR链路的条件，或者，也可以设置为确定不恢复NR链路的条件，具体可以视实际情况而定，本申请不做任何限定。
其中，关于M个业务传输速率的具体描述可以参考方法300中步骤S331的相关描述，不再赘述。
在该步骤中，根据M的大小，从M＝1以及M＞1的两种情况对实施例的进一步说明可以参考方法300中步骤S331中的情况B1和情况B2，此处不再赘述。
其中，在M＞1的情况中，终端设备根据定时器N确定是否恢复NR链路，具体描述可以参考S322的S3311和S3312，不再赘述。应理解，终端设备执行开启定时器N的动作可以在S422之后执行，也可以与S422同步执行，本申请不做任何限定。
实现中，该步骤可由终端设备的处理器执行。
S432、终端设备恢复NR链路。
关于该步骤的具体描述可以参考方法300中步骤S332的相关描述，不再赘述。
S441、终端设备启动定时器B。
在S432之后或在执行S432的同时，终端设备启动定时器B，在定时器B的时长内，不执行关于确定是否断开NR链路的动作，一是可以预留时间通过终端设备与接入网设备之间的交互尽可能恢复NR链路，二是尽可能让终端设备在一定时长内体验5G通信，三是也可以防止乒乓效应。
在定时器B的时长结束后，终端设备继续执行S421以及后续步骤，重复执行上述各个可能的步骤。作为示例而非限定，终端设备也可以先执行S413以及后续步骤。
实现中，该步骤可由终端设备的处理器执行。
需要说明的是，在上述任一个步骤中，可选地，若终端设备退出第一应用且NR链路被断开，则终端设备与4G接入网设备和5G接入网设备进行信息交互以恢复NR链路。可选地，若终端设备退出第一应用且NR链路未被断开，则终端设备保持当前的链路状态，采用LTE链路和NR链路进行通信。
应理解，这里所说的终端设备退出第一应用可以是终端设备关闭该第一应用，也可以是终端设备将在前台运行的第一应用退出变为在后台运行的应用。
下面，结合图8，对方法400中一种可能的实现方式中采用4种定时器进行NR链路的断开和恢复做一说明。
终端设备打开第一应用以及确定该第一应用为预设应用。终端设备启动定时器A，此外，无论当前的链路状态如何，终端设备可以默认系统中存在NR链路。在定时器A的时长结束后，终端设备启动定时器M，其中，定时器M的时长等于监测周期的时长与N的乘积，从定时器M的起始时间开始，终端设备确定N个监测周期内的N个业务传输速率是否满足小于第一开关门限的条件，若满足，则断开NR链路，并且，开启定时器N，若不满足，则重新开启定时器M，继续确定是否满足上述条件，如此反复执行，直到满足条件，断开NR链路，开启定时器N。终端设备开启定时器N，其中，定时器N的时长等于监测周期的时长与M的乘积，从定时器N的起始时间开始，终端设备确定M个监测周期内的M个业务传输速率是否满足大于第二开关门限的条件，若满足，则恢复NR链路， 并且，开启定时器B，若不满足，则重新开启定时器N，继续确定是否满足上述条件，如此反复执行，直到满足条件，恢复NR链路，开启定时器B。终端设备开启定时器B，在定时器B的时长内，在无异常情况下，NR链路不会被断开，终端设备可采用LTE链路和NR链路进行通信。
应理解，上述方法400中的各个步骤的过程仅为示意性说明，实现中，可以基于实际情况执行上述部分或全部步骤的功能和内在逻辑。
示例性地，方法400可以在包括步骤S412、S421、S422、S431、S432的情况下，添加其他任意可组合的步骤。例如，方法400可以包括S412、S417、S421、S422、S431、S432。再例如，方法400可以包括S412、S413、S417、S421、S422、S431、S432。再例如，方法400可以包括S412、S413、S417、S421、S422、S431、S432、S441。
还应理解，上述方法400中各过程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，S411和S412可以同时执行，也可以先执行S411再执行S412。再例如，S432和S441可以同时执行，也可以先执行S432再执行S441。
以上，结合图3至图8，对本申请的无线通信的方法做了详细说明。应理解，上述方法300和方法400可以单独实现，也可以相结合实现，只要逻辑上可实现即可，本申请不做任何限定。例如，在方法300中，也可以设置定时器B，在终端设备恢复NR链路的过程中打开定时器B，以尽可能实现NR链路的恢复以及使得用户在该定时器B的时长内体验5G通信。
下面，以手机作为终端设备的一例，结合图9至图17提供的可能的示意性场景图，对本申请提供的无线通信的方法做进一步说明。
在一种情况中，当系统的链路发生变化时，手机上显示的移动网络标识也会发生变化，例如，当手机采用LTE链路进行通信时，手机上显示的移动网络为4G，当手机采用LTE链路和NR链路进行通信时，手机上显示的移动网络为5G。
需要说明的是，现有协议并没有针对NSA组网下的5G图标的显示规则作出明确的定义，GSMA根据4G、NR网络的不同覆盖、不同状态的组合定义了几种状态，以及每种状态下图标的显示方案。作为参考，表6示出了网络在不同状态下的各种可能的配置，每个状态都有4种配置方式，运营商可以与终端厂商协商采用哪种配置方式。其中，配置D相对激进，NSA显示的概率很大，即使用户没有在核心网开户，只要具备5G终端就可以显示5G图标，而配置A则相对保守。上述方案仅仅只是GSMA的一个建议，3GPP目前并没有上述相关的内容。

下面，结合上述情况，对图9至图16所示的场景下4G和5G之间的切换做一说明。
图9所示为本申请提供的一种可能的示意性场景图。图9示出了用户操作终端设备加载不同业务的过程中移动网络在4G和5G之间切换的示意性场景图。如图9中的(a)所示，手机的屏幕显示系统显示了一种可能的显示界面，该显示界面包括位于显示界面上面的上界面801、位于显示界面中间位置的主界面802以及位于显示界面下方的下界面803。示例性地，上界面801可以显示运营商、手机当前所处的移动网络(4G或者5G)、手机当前的无线网络状态、手机的剩余电量以及时间等信息。示例性地，主界面802可以显示多款第三方应用程序，例如付款工具、任务卡商店、视频、音乐、聊天工具、卡包、设置、相机等。下界面803可以显示各种便捷操作按键，例如，返回键、home键和菜单键等。在图9中的(a)的显示界面中，上界面801显示的手机的移动网络为5G，表示手机处于双连接状态，采用NR链路和LTE链路进行通信，并且，用户准备打开聊天工具，该界面可以是手机开机后第一次实现双连接的显示界面，也可以是手机在任意状态下实现双连接的显示界面。在图9中的(b)中，用户已经打开聊天工具，主界面802变为聊天工具的界面，用于浏览聊天工具的界面的业务传输速率较低，可以断开NR链路，上界面801显示的移动网络变为4G，意味着手机采用LTE链路进行通信。在图9中的(c)中，用户退出了聊天工具，准备打开视频，当前的业务传输速率较低，继续采用LTE链路进行通信，上界面801显示的移动网络依然为4G。在图9中的(d)中，用户打开了视频，主界面802显示视频画面，业务传输速率较高，恢复NR链路，上界面801显示的移动网络变为5G。
在一种可能的设计中，当接收到用户打开某一应用超过一定的时间阈值之后，终端设备才根据当前是的传输速率来决定是否要进行关闭NR链路或者打开NR链路。
需要说明的是，在手机和接入网设备进行交互以断开NR链路或恢复NR链路时，可能需要时间才能断开或恢复NR链路，在该时段内虽然手机的业务传输速率也较低，显示的也可能依然是之前的NR网络，或者，在该时段内虽然手机的业务传输速率较高，显示 的也可能依然是之前的LTE网络。以断开NR链路为例，参考图10，在图10中的(a)中，手机加载的是视频，业务传输速率较高，上界面801显示的移动网络是5G，在图10中的(b)中，用户退出视频，业务传输速率较低，但是，由于时间太短，还未来得及断开NR链路，所以，上界面801显示的移动网络依然是5G，在图10中的(c)中，时间足够，已经断开了NR链路，所以，上界面801显示的移动网络变为4G
图11所示为本申请提供的另一种可能的示意性场景图，可以对应方法300的实施例。图11示出了用户操作终端设备加载不同业务的过程中移动网络在4G和5G之间切换的示意性场景图。在图11中的(a)和(b)中，图11中的(b)是图11中的(a)的最小化的界面，用户打开视频，观看的是高清视频(如图11中的(a)所示)，业务传输速率较高，上界面801显示的移动网络是5G。在图11中的(c)和(d)中，图11中的(d)是图12中的(c)的做小化的界面，用户从高清视频切换至标清视频(如图11中的(c)所示)，业务传输速率较低，上界面801显示的移动网络是4G。
图12所示为本申请提供的另一种可能的示意性场景图，可以对应方法300的实施例。图12示出了在不同信号强度的情况下用户操作相同业务的过程中移动网络在4G和5G之间切换的示意性场景图。在图12中的(a)，上界面801显示的移动网络为5G，表示手机处于双连接状态，采用NR链路和LTE链路进行通信，并且，上界面801显示的信号强度较好，此外，用户准备打开地图。在图12中的(b)中，用户已经打开地图，显示地图内容，业务传输速率较低，断开NR链路，上界面801显示的移动网络变为4G，上界面801显示的信号强度较好。在图12中的(c)中，上界面801显示的信号强度变得很差，基于此，手机计算得到的第一开关门限以及第二开关门限都降低，针对于相同的导航业务，可以理解为，在信号不好的时候需要NR网络提速，因此，可以恢复NR链路，以满足用户体验，上界面801显示的移动网络变为5G。在图12中的(d)中，上界面801显示的信号强度变好，基于此，手机计算得到的第一开关门限以及第二开关门限升高，针对相同的导航业务，可以理解为，在信号较好的时候LTE网络完全满足需求，可以断开NR链路，上界面801显示的移动网络变为4G。
图13所示为本申请提供的另一种可能的示意性场景图，可以对应方法400的实施例。图13示出了用户使用预设应用以及退出该应用的过程中移动网络在4G和5G之间切换的示意性场景图。示例性地，地图为预设应用，应用市场为非预设应用。在图13中的(a)中,上界面801显示的移动网络为5G，表示手机处于双连接状态，采用NR链路和LTE链路进行通信，此外，用户准备打开地图。在图13中的(b)中，用户开始使用地图进行导航，地图为预设应用，终端设备监控地图的业务传输速率，业务传输速率较低，上界面801显示的移动网络变为4G。在图10中的(c)中，用户退出地图，可以恢复NR链路，上界面801显示的移动网络变为5G。在图13的(d)中，用户准备打开应用市场，以下载应用，上界面801显示的移动网络依然为5G，并且，手机不需要监控业务传输速率。在图13中的(e)中，用户下载腾讯新闻，由于手机不监控业务传输速率，不需要对NR链路做处理，上界面801显示的移动网络依然为5G。
图14所示为本申请提供的另一种可能的示意性场景图，可以对应方法400的实施例，可以与图13中的(b)参考对比。图14示出了用户使用预设应用且手机处于通话模式下移动网络的状态的示意性场景图。示例性地，地图为预设应用。在图14中的(a)中，上 界面801显示的移动网络为5G，表示手机处于双连接状态，采用NR链路和LTE链路进行通信，上界面801显示手机处于通话模式中，并且，用户准备打开地图进行导航。在图14中的(b)中，用户开始使用地图进行导航，虽然地图为预设应用，但是，由于手机处于通话模式中，手机不监控业务传输速率，上界面801显示的移动网络依然为5G，可以和图13中的(b)对比，在图13中的(b)中，手机未处于通话模式中，业务传输速率较低，移动网络变为4G。
图15所示为本申请提供的另一种可能的示意性场景图，可以对应方法400的实施例，可以与图13中的(b)参考对比。图15示出了用户使用预设应用的应用且手机处于充电模式下移动网络的状态的示意性场景图。示例性地，地图为预设应用。在图15中的(a)中，上界面801显示的移动网络为5G，表示手机处于双连接状态，采用NR链路和LTE链路进行通信，上界面801显示手机处于充电模式中，并且，用户准备打开地图进行导航。在图15中的(b)中，用户开始使用地图进行导航，虽然地图为预设应用，但是，由于手机处于充电模式中，手机不监控业务传输速率，上界面801显示的移动网络依然为5G，可以和图13中的(b)对比，在图13中的(b)中，手机未处于充电模式中，业务传输速率较低，移动网络变为4G。
图16所示为本申请提供的另一种可能的示意性场景图，可以对应方法400的实施例，可以与图13中的(b)参考对比。图16示出了用户使用预设应用的应用且手机处于性能优化模式下移动网络的状态的示意性场景图。示例性地，地图为预设应用。在图14中的(a)中，上界面801显示的移动网络为5G，表示手机处于双连接状态，采用NR链路和LTE链路进行通信，并且，用户准备打开设置。在图16中的(b)中，用户打开设置中电池选项的性能优化模式，使得手机处于性能最优的模式，这样，无论后续用户打开哪种应用，都不会监控业务传输速率以断开NR链路。在图16中的(c)和(d)中，用户退出设置，打开地图进行导航，虽然地图为预设应用，但是，由于手机处于性能优化模式中，手机不监控业务传输速率，上界面801显示的移动网络依然为5G，可以和图13中的(b)对比，在图13中的(b)中，手机未处于性能优化模式中，业务传输速率较低，移动网络变为4G。
在另一些可能的情况中，只要手机支持NR网络，无论手机在运行过程中采用LTE链路还是采用LTE链路与NR链路进行通信，手机上显示的移动网络都一直显示为5G，不过，可以在其他界面中查看当前的实际网络是LTE网络还是NR网络。下面，结合上述情况，以图17所示的场景为例，对LTE网络和NR网络之间的切换做一简单说明，其余类似于图9至17所示的场景中，在该情况中显示移动网络的图标一直是5G，实际网络可以参考图17的示例获得，因此，不再对图9至图16所示的场景赘述。
应理解，图17所示的用于显示当前的实际网络的界面仅为示意性说明，不应对本申请构成限定。
图17所示为本申请提供的另一种可能的示意性场景图，图17中的(a)可以对应图9中的(a)，图17中的(c)可以对应图9中的(b)。在图17中的(a)中，上界面801显示的手机的移动网络为5G，主界面802中用户准备打开聊天工具，对应地，在相同时间点，在例如设置中关于网络的描述中，打开例如图17中的(b)所示的描述网络的显示界面，在信号强度的描述中，可以看到4G(即LTE)网络和5G(即NR)都具有信号， 表示手机目前处于双连接状态，采用NR链路和LTE链路进行通信。在图17中的(c)中，用户已经打开聊天工具的界面，主界面802变为聊天工具的界面，用于浏览聊天工具的界面的业务传输速率较低，可以断开NR链路，上界面801显示的移动网络依然为5G，对应地，在相同时间点，在例如设置中关于网络的描述中，打开例如图17中的(d)所示的描述网络的显示界面，在信号强度的描述中，可以看到只要4G(即LTE)网络具有信号，5G(即NR)网络没有信号，表示手机目前仅采用LTE链路进行通信。

应理解，第一开关门限也可以为第一应用预配置的门限，具体描述没有参考方法300中关于确定第一开关门限和第二开关门限中的方式中的方式2的相关描述。
可选地，在S620之前，该方法还包括：在前台运行第一应用，该第一应用为预设应用。
也就是说，在前台运行的第一应用为预设应用的情况下，终端设备检测业务传输速率，后续，在检测到业务传输速率小于第一开关门限的情况下，发送第一指令。
对应地，在前台运行的第一应用是非预设应用的情况下，终端设备不检测业务传输速 率，采用LTE链路和NR链路进行通信。
可选地，该第一应用为以下任一项应用：导航类应用、阅读类应用、游戏类应用、可内嵌视频的应用。
可选地，该终端设备未处于优先模式，该优先模式包括以下至少一项：通话模式、充电模式、性能优化模式或热点共享模式。
也就是说，在终端设备在前台运行的第一应用为预设应用且终端设备未处于优先模式的情况下，终端设备检测业务传输速率，后续，在检测到业务传输速率小于第一开关门限的情况下，发送第一指令。
其中，关于在前台运行的第一应用为预设应用的具体描述可以参考方法400中的步骤S412的相关描述。
可选地，该方法还包括：

在该第一定时器超时后，检测该终端设备的业务传输速率。
也就是说，在前台运行第一应用之后，启动第一定时器，在第一定时器超时后，检测终端设备的业务传输速率，后续，在检测到业务传输速率小于第一开关门限的情况下，发送第一指令。
可选地，该方法还包括：
从前台退出该第一应用；
接入网络设备为该终端设备配置的小区，以恢复该NR链路；
在该NR链路恢复之后，采用该LTE链路和该NR链路进行通信。

此外，通过设置预设应用，在第一应用为预设应用的情况下检测终端设备的业务传输速率以确定是否断开NR链路，以在业务传输速率小于第一开关门限情况下断开NR链路，在不影响速率方面的用户体验的情况下，可以有效地降低终端设备的功耗，而且，对应地，可以在第一应用是非预设应用的情况下，不检测终端设备的业务传输速率，采用LTE链路和NR链路进行通信，以尽可能优先保证用户对非预设应用的速率需求，不影响用户对5G通信的体验。
