发明内容
本申请实施例提供一种通信方法和通信装置，用于防止移动数据产生较大传输时延。
为达到上述目的，本申请的实施例采用如下技术方案：
第一方面，提供了一种由终端设备执行的通信方法，包括：确定满足LTE小区与NR小区之间的互操作的抑制基础条件；统计发生LTE小区与NR小区之间的互操作异常事件的时间和次数；如果在第一预设时间内互操作异常事件的次数大于或等于事件次数门限，并且，满足从LTE小区至NR小区的互操作的抑制进入条件，则在第二预设时间内，对从LTE小区至NR小区的互操作进行抑制。
本申请实施例提供的通信方法，当满足从LTE小区至NR小区的互操作的抑制基础条件时，如果在第一预设时间内互操作异常事件的次数大于或等于事件次数门限，并且，满足从LTE小区至NR小区的互操作的抑制进入条件，则在第二预设时间内，终端设备对从LTE小区至NR小区的互操作进行抑制，从而防止移动数据产生较大传输时延。
在一种可能的实施方式中，满足LTE小区与NR小区之间的互操作的抑制基础条件包括：终端设备处于亮屏状态，并且，终端设备前台运行的业务或应用被允许使用移动数据，并且，终端设备前台运行的至少一个业务或应用属于白名单或者前台运行的所有业务或应用不属于黑名单；其中，白名单包括：当在前台运行时，允许对从LTE小区至NR小区的互操作进行抑制的业务或应用；黑名单包括：当在前台运行时，不必对从LTE小区至NR小区的互操作进行抑制的业务或应用。一个业务或应用只能属于白名单或黑名单中的一个，不能同时既属于白名单又属于黑名单。可以选择白名单和黑名单中的一种或两种方式来判断是否满足从LTE小区至NR小区的互操作的抑制基础条件。其中，黑名单的优先级高于白名单的优先级，当黑名单和白名单同时生效 时，如果针对同一应用或业务的判断逻辑存在冲突，则以黑名单的判断逻辑为准。
在一种可能的实施方式中，统计LTE小区与NR小区之间的互操作异常事件的时间和次数，包括：当发生互操作异常事件时，如果时间戳队列中存储的互操作异常事件的时间的数目小于事件次数门限，则将所发生的互操作异常事件的时间加入时间戳队列；如果时间戳队列中最早发生的互操作异常事件的时间与该所发生的互操作异常事件的时间之差大于第一预设时间，则从所述时间戳队列中删除最早发生的互操作异常事件的时间。即通过时间戳队列存储发生互操作异常事件的时间，时间戳队列中时间的数目即表示互操作异常事件的时间的次数。但是需要说明的是，本申请不限定必须采用这种方式来统计互操作异常事件的时间和次数，还可以采用其他方式来统计互操作异常事件的时间和次数。

本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请，下面将结合附图对本申请的实施例进行详细描述。
首先对本申请涉及的概念进行描述。
独立组网(stand alone，SA)和非独立组网(non-stand alone，NSA)：NSA指第四代(4th generation，4G)通信(也称长期演进(long term evolution，LTE))与第五代(5th generation，5G)通信(也称新空口(new radio，NR))联合组网，SA指5G独立组网。在NSA中没有独立的5G核心网，而是采用双连接的方式，即在无线侧NR接入网设备和LTE接入网设备共存，在核心网侧5G与4G共用4G核心网。在SA中，5G核心网与4G核心网是独立的，LTE接入网设备和NR接入网设备也是独立的。本申请实施例以SA为例，但并不意在限定于此。
如图1所示，本申请实施例提供的通信系统100包括终端设备101、第一接入网设备102、第二接入网设备103、核心网104、数据网络(data network，DN)105。
DN 105指的是为终端设备101提供移动数据传输服务的运营商网络，例如可以为互联网协议(internet protocol，IP)多媒体子系统(IP multimedia subsystem，IMS)、互联网(Internet)等。

核心网104用于提供DN 105与接入网设备之间用户面的数据传输，还用于提供与接入网设备之间信令面的数据传输。对于SA来说，核心网104可以包括5G核心网和4G核心网，示例性的，当终端设备101通过第二接入网设备103接入4G网络时，由4G核心网提供用户面和信令面的数据传输，当终端设备101通过第一接入网设备102接入5G网络时，由5G核心网提供用户面和信令面的数据传输。

在终端设备移动过程中，可能发生小区切换，在SA中，终端设备通过LTE与NR之间的互操作(例如重定向、重选、切换)，以实现在NR小区与LTE小区之间的切换。由于互操作导致移动数据的传输时延很大(有时长达800ms)，会导致一些传输时延敏感(要求低于100ms)的业务或应用(例如游戏)产生卡顿，影响用户体验，示例性的，图3示出了前台运行游戏时，传输时延影响用户体验的一种场景。本申请实施例提供的通信方法，当满足一定条件时，终端设备对从LTE小区至NR小区的互操作进行抑制，防止移动数据产生较大传输时延。
如图4所示，本申请实施例提供了一种通信方法，包括S101-S114：
S101、终端设备判断是否满足从LTE小区至NR小区的互操作的抑制基础条件。如果满足从LTE小区至NR小区的互操作的抑制基础条件则执行步骤S102，否则执行 步骤S110。
本申请实施例涉及的从LTE小区至NR小区的互操作包括以下至少一项：从LTE小区重定向到NR小区，从LTE小区切换到NR小区，从LTE小区重选到NR小区。如无特别说明，其中，本申请涉及的LTE小区指终端设备所在的LTE小区，NR小区为该LTE小区的邻区。
满足从LTE小区至NR小区的互操作的抑制基础条件包括：终端设备处于亮屏状态，并且，终端设备前台运行的业务或应用被允许使用移动数据，并且，终端设备前台运行的至少一个业务或应用属于白名单或者前台运行的所有业务或应用不属于黑名单。
示例性的，如图3所示，前台运行业务或应用的一种场景为前台运行游戏或其他应用；如图5所示，前台未运行业务或应用的一种场景为前台只显示桌面。并且前台可以运行不限于一个业务或应用，示例性的，如图6所示，在分屏显示场景，可以在前台左侧运行导航应用，在前台右侧运行视频聊天应用。
白名单包括：当在前台运行时，允许对从LTE小区至NR小区的互操作进行抑制的业务或应用。黑名单包括：当在前台运行时，不必对从LTE小区至NR小区的互操作进行抑制的业务或应用。一个业务或应用只能属于白名单或黑名单中的一个，不能同时既属于白名单又属于黑名单。
可以选择白名单和黑名单中的一种或两种方式来判断是否满足从LTE小区至NR小区的互操作的抑制基础条件。其中，黑名单的优先级高于白名单的优先级，当黑名单和白名单同时生效时，如果针对同一应用或业务的判断逻辑存在冲突，则以黑名单的判断逻辑为准。在终端设备处于亮屏状态，并且，终端设备前台运行的业务或应用被允许使用移动数据这两个条件满足的情况下：如果前台运行的至少一个业务或应用属于白名单，则允许对从LTE小区至NR小区的互操作进行抑制，执行步骤S102；如果前台运行的所有业务或应用均不属于白名单，则不必对从LTE小区至NR小区的互操作进行抑制，执行步骤S110。如果前台运行的所有业务或应用均属于黑名单，则不必对从LTE小区至NR小区的互操作进行抑制，执行步骤S110；如果前台运行的至少一个业务或应用不属于黑名单，则允许对从LTE小区至NR小区的互操作进行抑制，执行步骤S102。
示例性的，如图7所示，互操作抑制功能可以通过互操作抑制开关(图7中“业务体验增强”旁边的开关)来控制，当互操作抑制开关打开时互操作抑制功能打开，当互操作抑制开关关闭时互操作抑制功能关闭。进一步地，当互操作抑制开关打开时，可以显示白名单和/或黑名单，在列表(白名单或黑名单)中显示各个业务或应用的子开关，当子开关打开时将对应的业务或应用加入该列表中，当子开关关闭时将对应的业务或应用从列表中移除。结合图6中前台运行了导航应用和视频聊天应用，图7中白名单和黑名单所实现的功能均为：由于前台运行了视频聊天应用，所以允许对从LTE小区至NR小区的互操作进行抑制。
S102、终端设备新建时间戳队列。
即终端设备在新建时间戳队列时可以动态分配内存以存储时间戳队列。时间戳队列按照LTE小区与NR小区之间的互操作异常事件发生的时间依次存储各个时间，LTE 小区与NR小区之间的互操作异常事件(后文可以简称为互操作异常事件)包括以下事件的至少一项：从NR小区重定向到LTE小区，从NR小区切换到LTE小区，从NR小区重选到LTE小区，从LTE小区重定向到NR小区失败，从LTE小区切换到NR小区失败，从LTE小区重选到NR小区失败。由于新建5G的缘故，5G接入网设备或5G核心网的质量不好或不稳定，所以导致发生上述互操作异常事件，因此要对从LTE小区至NR小区的互操作进行抑制。
S103、终端设备判断是否发生互操作异常事件，如果发生互操作异常事件，则执行步骤S104，否则执行步骤S111。
S104、终端设备判断互操作异常事件的总次数是否大于或等于事件次数门限，如果互操作异常事件的次数大于或等于事件次数门限，则执行步骤S105，否则执行步骤S112。
互操作异常事件的总次数等于时间戳队列中存储的互操作异常事件的时间的数目加1，示例性的，如果时间戳队列中存储的互操作异常事件的时间的数目为2，则加上步骤S103检测到最近发生的互操作异常事件，互操作异常事件的总次数为3。
终端设备可以根据触发抑制的业务或应用来确定事件次数门限，即事件次数门限是可变的，这样可以针对不同业务或应用的特点来确定不同的互操作异常事件次数门限。
S105、终端设备判断时间戳队列中最早发生的互操作异常事件的时间与最近发生的互操作异常事件的时间之差是否小于或等于第一预设时间，如果该差值小于或等于第一预设时间则执行步骤S106，否则执行步骤S112。
需要的说明的是，步骤S104和S105的执行顺序不分先后，例如，可以先执行步骤S104后执行步骤S105，或者，可以先执行步骤S105后执行步骤S104。
终端设备可以根据触发抑制的业务或应用来确定第一预设时间的长度，即第一预设时间的长度是可变的，这样可以针对不同业务或应用的特点来确定不同的互操作异常事件时间间隔。
S106、终端设备判断是否满足从LTE小区至NR小区的互操作的抑制进入条件，如果满足则执行步骤S107，否则执行步骤S114。
满足从LTE小区至NR小区的互操作的抑制进入条件包括以下至少一项：终端设备所在LTE小区的参考信号接收功率(reference signal receiving power，RSRP)大于第一信号强度门限(RSRP数值越大则信号强度越高，即终端设备所在LTE小区的信号强度较高)，终端设备所在LTE小区的参考信号接收质量(reference signal receiving quality，RSRQ)大于第一信号质量门限(RSRQ数值越大则信号质量越好，即终端设备所在LTE小区的信号质量较好)，终端设备所在LTE小区的信噪比(signal noise ratio，SNR)大于第一信噪比门限(SNR数值越大则信噪比越好，即终端设备所在LTE小区的信号质量较好)，终端设备的移动速度小于第一速度门限(即终端设备处于低速运动状态或静止状态)。
S107、终端设备清空时间戳队列，在第二预设时间内对从LTE小区至NR小区的互操作进行抑制，执行步骤S108。
终端设备在清空时间戳队列后可以回收存储时间戳队列的内存。
终端设备对从LTE小区至NR小区的互操作进行抑制包括但不限于以下几种实施方式：
在一种可能的实施方式中，终端设备可以对从LTE小区至NR小区的B1测量报告上报和B2测量报告上报进行抑制。从LTE小区至NR小区的B1测量报告上报指：当NR小区的RSRP大于第一门限时上报B1测量报告，从LTE小区至NR小区的B2测量报告上报指：当LTE小区的RSRP小于第二门限并且NR小区的RSRP大于第三门限时，上报B2测量报告。因此，对从LTE小区至NR小区的B1测量报告上报进行抑制指：当NR小区的RSRP大于第一门限时不再上报B1测量报告；对从LTE小区至NR小区的B2测量报告上报进行抑制指：当LTE小区的RSRP小于第二门限并且NR小区的RSRP大于第三门限时不再上报B2测量报告。该实施方式可以防止终端设备执行从LTE小区至NR小区的互操作。
在另一种可能的实施方式中，终端设备可以禁用SA功能，使用NSA功能，使得终端设备不支持SA功能，支持NSA功能。
终端设备可以根据触发抑制的业务或应用来确定第二预设时间的长度，即第二预设时间的长度是可变的，这样终端设备可以针对不同业务或应用的特点来抑制不同时间。触发抑制的业务或应用可以指前文所述的满足从LTE小区至NR小区的互操作的抑制基础条件所涉及的业务或应用，例如，可以为终端设备前台运行的属于白名单的业务或应用，或者，可以为终端设备前台运行的不属于黑名单的业务或应用。
S108、终端设备判断是否满足从LTE小区至NR小区的互操作的抑制退出条件，如果满足从LTE小区至NR小区的互操作的抑制退出条件，则执行步骤S109，否则重新执行步骤S108。
满足从LTE小区至NR小区的互操作的抑制退出条件包括以下至少一项：触发抑制的业务或应用退出前台，触发抑制的业务或应用被禁止使用移动数据，终端设备处于熄屏状态，终端设备所在LTE小区的RSRP小于第二信号强度门限(即终端设备所在LTE小区的信号强度较低)，终端设备所在LTE小区的RSRQ小于第二信号质量门限(即终端设备所在LTE小区的信号质量较差)，终端设备所在LTE小区的SNR小于第二信号信噪比门限(即终端设备所在LTE小区的信号质量较差)，抑制的时间大于前文所述的第二预设时间，终端设备切换至其他LTE小区，终端设备的移动速度大于第二速度门限，终端设备的NR通信功能被关闭或打开，终端设备切换至飞行模式，终端设备的使用移动数据的用户识别卡SIM卡被切换，SIM卡被热插拔。
其中，第二信号强度门限小于或等于第一信号强度门限，第二信号质量门限小于或等于第一信号质量门限，第二信噪比门限小于或等于第一信噪比门限，第二速度门限大于或等于第一速度门限。
S109、终端设备停止对从LTE小区至NR小区的互操作进行抑制，执行步骤S110。
终端设备停止对从LTE小区至NR小区的互操作进行抑制包括但不限于以下几种实施方式：
在一种可能的实施方式中，终端设备可以允许对从LTE小区至NR小区的B1测量报告上报和B2测量报告进行上报；其中，允许对从LTE小区至NR小区的B1测量报告进行上报指：当NR小区的RSRP大于第一门限时上报B1测量报告；允许对从 LTE小区至NR小区的B2测量报告进行上报指：允许当LTE小区的RSRP小于第二门限并且NR小区的RSRP大于第三门限时上报B2测量报告。允许这两个测量报告的上报可以允许终端设备执行从LTE小区至NR小区的互操作。
在另一种可能的实施方式中，终端设备可以恢复SA功能。
需要说明的是，终端设备停止对从LTE小区至NR小区的互操作进行抑制所选择的方式与终端设备对从LTE小区至NR小区的互操作进行抑制的方式相对应。当终端设备对从LTE小区至NR小区的互操作进行抑制时，如果采用对从LTE小区至NR小区的B1测量报告上报和B2测量报告上报进行抑制，那么，当终端设备停止对从LTE小区至NR小区的互操作进行抑制时，采用允许对从LTE小区至NR小区的B1测量报告上报和B2测量报告进行上报。当终端设备对从LTE小区至NR小区的互操作进行抑制时，如果采用禁用SA功能，使用NSA功能，那么，当终端设备停止对从LTE小区至NR小区的互操作进行抑制时，采用恢复SA功能。
S110、终端设备退出互操作抑制流程。
S111、终端设备判断是否满足从LTE小区至NR小区的互操作的抑制基础条件。如果满足从LTE小区至NR小区的互操作的抑制基础条件则执行步骤S103，否则执行步骤S113。
S112、终端设备更新时间戳队列，执行步骤S111。
时间戳队列中存储的互操作异常事件的时间的数目可以小于或等于事件次数门限，当发生互操作异常事件时，如果时间戳队列中存储的互操作异常事件的时间的数目小于事件次数门限时，可以将最近发生的互操作异常事件的时间加入时间戳队列中。根据先入先出的原则，在满足一定条件时也可以将时间戳队列中最早发生的互操作异常事件的时间删除，例如，如果时间戳队列中最早发生的互操作异常事件的时间与最近发生的互操作异常事件的时间之差大于第一预设时间，则可以删除时间戳队列中最早发生的互操作异常事件的时间。这样不会增加时间戳队列的存储空间，并且保证时间戳队列中存储最近几次的互操作异常事件的时间，并且存储的最早时间和最晚时间的差小于或等于第一预设时间。
S113、终端设备清空时间戳队列，执行步骤S110。
终端设备在清空时间戳队列后可以回收存储时间戳队列的内存。
S114、终端设备清空时间戳队列，执行步骤S101。
终端设备在清空时间戳队列后可以回收存储时间戳队列的内存。

S201、终端设备确定满足从LTE小区至NR小区的互操作的抑制基础条件。
关于“满足从LTE小区至NR小区的互操作的抑制基础条件”参照步骤S101。
S202、终端设备统计发生LTE小区与NR小区之间的互操作异常事件的时间和次数。

S203、如果在第一预设时间内互操作异常事件的次数大于或等于事件次数门限，并且，满足从LTE小区至NR小区的互操作的抑制进入条件，则在第二预设时间内，终端设备对从LTE小区至NR小区的互操作进行抑制。
关于“满足从LTE小区至NR小区的互操作的抑制进入条件”参照步骤S106，关于“从LTE小区至NR小区的互操作”参照步骤S101，关于“终端设备对从LTE小区至NR小区的互操作进行抑制”参照步骤S107。

可选的，如图9所示，该通信方法还包括：
S204、在第二预设时间内，当满足从LTE小区至NR小区的互操作的抑制退出条件时，终端设备停止对从LTE小区至NR小区的互操作进行抑制。
