具体实施方式
在无线系统中，不同制式、同一制式、不同系统的基站或接入点协同组网时，由于单个基站的带宽资源和覆盖范围有限，因此，集中多个小区或者基站的无线资源来为用户提供服务，更易于满足用户的容量需求和覆盖要求，这种方式通常称之为多连接。
以LTE系统为例，常用的多连接方式包括载波聚合、CoMP(Coordinated Multipoint transmission/reception)以及双连接等。具体地，双连接(Dual Connectivity，以下简称DC)是指UE(终端设备)在RRC(Radio Resource Control Layer，无线链路控制层)连接态下的操作模式，对于UE(终端设备)配置了一个主小区组(Master Cell Group)和一个辅小区组(Secondary Cell Group)，提供基站间非理想传输条件下的性能解决方案。这种方式下，为了规避MAC(Media Access Control，媒体介入控制)层调度过程中的时延和同步要求，数据在PDCP(Packet Data Convergence Protocol，分组数据汇聚)层进行分割和合并，随后将用户数据流通过多个基站同时传送给用户。从而有助于实现用户性能提升，对用户总体吞吐量和切换时延都有帮助。LTE系统中采用双连接时，数据在核心网或者PDCP层进行分割后，将用户数据流通过多个基站同时传送给用户，核心网和无线网都存在多种选择，并且采用双连接时，需考虑数据承载等问题。
值得说明的是，本申请以4G LTE((Long Term Evolution，长期演进))和5G NR(New Radio，5G接入网)的双连接为例，但不局限LTE与5G之间，在一种可能的实施方式中，也可是多种不同的通信制式之间，例如4G与5G之间，如图1所示，第一基站可以是LTE eNB基站，第二基站可以是gNB基站；在一种可能的实施方式，也可是同一代通信技术不同的基站类型，例如LTE基站与增强型LTE基站(eNB)；在一种可能的设计中，也可以是不同的接入点或系统之间的连接，例如，LTE接入点与WIFI、蓝牙等接入点；在一种可能的设计中，本申请也可以扩展到多连接技术，例如，可以连接多个不同制式的基站，或者基站、WiFi等不同系统组合的系统。
现有5G标准定义了多种组网方式，包括独立组网(Standalone，简称SA)和非独立组网(Non-standalone，简称NSA)方式，以非独立组网方式为例，包括Option 3/3a/3x、Option 4/4a、Option 7/7a/7x等多种可能的方式，以Option3/3a/3x为例，在4G基站(eNB)为主站，5G基站(gNB)为从站，并沿用LTE核心网，不需要新的5G核心网，所有的控制面信令都经由eNB转发，数据流的传输对应三种方式：可以是eNB将数据分流给gNB，或者EPC(Evolved Packet Core，LTE核心网)将数据分流至gNB，或者gNB可将数据分流至eNB。此场景以eNB为主基站，所有的控制面信令都经由eNB转发。LTE eNB与NR(New Radio)gNB采用双链接的形式为用户提供高数据速率服务。
以Option 4/4a为例，Option4同时引入了NGC(Next Generation Core)和gNB。但是gNB没有直接替代eNB，在此场景中，核心网采用5G的NGC，eNB和gNB都连接至NGC。所有的控制面信令都经由gNB转发，数据连的传输对应有两种方式：gNB将数据分流给eNB，NGC将数据分流至eNB。
上述只是示例性的提供了几种常见的典型DC的连接方式，本申请并不对此作出限定。
值得说明的是，4G-5G制式内的DC表示UE同时与4G基站和5G基站保持双连接，同时利用两个基站的无线资源进行业务传输。控制面承载在主站上，数据可承载在主站和辅站，根据数据在主站和辅站上的分布情况，可以分为以下4种DC承载类型：
a.MCG承载(数据只在主站上)
b.SCG承载(数据只在辅站上)
c.MCG Split承载(数据在主站分流)
d.SCG Split承载(数据在辅站分流)
图2根据本申请一种可能的实施方式提供的数据分流的第一示意图。
如图2所示，在双连接下，以下行数据传输为例，数据流在PDCP(Packet Data Convergence Protocol，分组数据汇聚)层上分离和合并，随后将数据流通过多个基站同时传送给终端设备。在这种情况下，一个PDCP实体可以关联两个RLC(Radio Link Control，无线链路层控制协议)实体，可以理解为PDCP层将数据流通过RLC1、RLC2链路传输至RLC层，具体地，RLC1链路可以理解为LTE链路，RLC2链路可以理解为NR链路，每个RLC实体分别对应LTE空口和NR空口。在这种场景下，PDCP的数据流会根据获取的授权，将PDCP报文分别在LTE和NR的空口上进行发送。此种方式可以称之为MCG Split承载模式。
同样，如果PDCP层只有关联一个RLC实体，此时PDCP层的数据直接传输至RLC层，此种方式称之为MCG承载(数据只在主站上传输)。
同样，如果此时数据在NR PDCP层的数据上传输，即数据在辅站上传输，此时也只关联一个NR RLC实体，即NR PDCP层的数据直接传输至NR RLC层，此种方式称之为SCG承载(数据只在辅站上传输)。
在一些实施例中，每一个RLC实体可以至少对应一条承载链路，在一些实施例，RLC层也可以有多个RLC实体。
图3根据本申请一种可能的实施方式提供的数据分流的第二示意图。
如图3所示，LTE eNB为主站，gNB为辅站，数据在NR PDCP层汇聚，一个NR PDCP实体可以关联两个RLC(Radio Link Control，无线链路层控制协议)实体，对应的NR RLC层与RLC层，此时数据在辅承载上分流，此种方式称之为SCG Split承载(数据在辅站分流)。
在此种情况下，为了避免4G基站处理能力的瓶颈，最大限度地减少原来的4G基站升级，尽可能地降低设备研发和建网成本，LTE-NR双连接规定也可由SCG分离承载，即下行数据流即可由5G从站传送到4G主站，再传送到手机。
图4根据本申请一种可能的实施方式提供的数据分流的第三示意图。
如图4所示，在上行数据传输中，数据流在PDCP汇聚后，可以按照一定的预定义策略进行分流传输。在一些实施例中，可以是平均分配数据流至两条链路上；在一些实施例中，可以是按照链路质量传输至两条链路上；在一些实施例，如果 PDCP传输的数据流的值小于分流传输的阈值，则在主承载上传输，例如图4中所示的链路1。
值得说明的是图中的链路1，链路2是为了便于描述，并非对本申请的限定。
在一些实施中，一个层中可以有多个实体，例如，RLC中可以有两个RLC实体，对应两条承载两路，本申请对此不作限定。
本申请中的UE(用户设备)可以是供消费者使用的任意应用型的电子设备。用户设备的示例包括但不限于，智能手机、平板电脑、电视、投影仪、智能手表、智能眼镜(例如，谷歌眼镜)、穿戴式小配件(例如，智能腕表、T恤、项链或鞋)、媒体(例如，音乐和/或视频)播放器、游戏机、游戏控制台和控制器、电子书(ebook)阅读器、云终端或车载媒体系统。用户设备可以是穿戴式设备(例如，智能手表或智能眼镜)或非穿戴式设备(例如，电视或平板电脑)。此外，用户设备可具有任意合适的操作系统(OS)，例如Android、iOS、Windows、Linux、Unix等。
进一步地，用户设备可以支持多种不同制式的移动通信技术，包括2G/3G/4G/5G，还可以支持WiFi、蓝牙等。
如图5所示，在一些实施例中，可以理解为RLC层有RLC1实体，RLC2实体，其中RLC1实体为支持LTE数据传输，RLC2实体为支持NR数据传输，但本申请对此并不作出限定。
以上行数据为例，当上层数据传输到PDCP层时，其数据报文具有SN(Serial Number，序列号)，可以理解为，数据传输到PDCP层时，被添加了SN编号。正常的情况下，下行的PDCP数据报文会按SN的编号升序到达，接收端接收到PDCP的报文如果是连续的，则直接递交给上层应用。
而在针对Split模式，上层数据传到PDCP层时，PDCP需要将数据进行分流，在一些情况下，例如，如果某一链路的质量不好，则传递的PDCP报文无法及时传递到对端，这时因为接收端无法获取到连续的PDCP数据包，就会出现另一链路等待PDCP报文的问题。反之，如果另一链路质量不好，也会存在同样的问题。
如图6所示，提供一种下行的数据的传输终端设备，终端设备接收到来自NR基站和LTE基站的数据，数据在PDCP层汇合，在一些场景下，由于网络等问题，两条链路的时延可以有所不同，会出现数据等待或者卡顿的情况。
基于此，如图7所示，本申请实施例提供一种新的分流数据的方法，首先，以终端设备的上行数据为例，可以根据终端设备当前所运行的应用程序来确定是否对上行数据进行分流传输，具体的：
步骤701：终端设备运行第一应用程序；
终端设备可以接收用户打开应用程序的操作，例如可以是在桌面点击应用程序的图标，也可以是通过状态栏、负一屏等快捷方法的打开应用，其中终端设备处于双连接的网络，即终端设备可以通过LTE链路和NR链路进行数据传输，终端的桌面的网络标识可以显示5G或者4G网络标识。
在一些实施例中，还可以是接收用户的操作将后台应用程序切换至前台任务。
步骤702：终端设备确定第一应用程序是否为预设应用程序，当第一应用程序为预设应用时，可以执行步骤407；当第一应用程序为非预设类型的时候，可以执行步骤703.
步骤703：当终端设备确定第一应用程序为非预设应用程序的时候，终端设备可以按照第一数据传输策略进行数据发送。
在一些实施例中，第一数据传输策略可以是指不分流数据包进行传输，即通过优先级较高的通道进行传输，值得说明的是，在现有的非独立组网NSA模式下，为了更大限度的利用NR资源，通常设置NR通道的优先较高，即默认通过NR通道来进行上行数据的传输。具体地，因为现有的协议规定了数据的分流机制可以根据数据包的大小，通过设置分流门限来决定分流，为了达到NR通道进行上行数据的传送，可以将分流的门限设置较大(例如无穷大)，从而达到数据包不分流进行传输。具体实现如下：
Figure PCTCN2021081412-appb-000001
Ul-data Duplication Threshold表示上行数据包的复制包的门限。
Ul-data split Threshold表示上行分流门限。
在一些实施例中，还可以按照网络或者UE配置，通过优先级较高的LTE或者NR链路进行传输运行第一应用程序的数据包，链路的优先级可以基于链路的时延、丢包率、信号强度或质量、缓存区数据大小或数量、TA(Timing Advance,定时提前)、MAC层误码率、信噪比(SINR)、SR连续发送最大值是指SR-TransMax、T310定时器、待发送数据包的大小是否启动等来进行设置，例如当NR链路的信号质量好于LTE链路的信号质量，可以通过NR链路发送运行第一应用程序的数据包至网络。
在另一些实施例中，第一数据传输策略还还可以是指分流数据包进行传输，例如可以是当判断数据包是否大于阈值，当数据包大于阈值的时候，可以进行分流传输，即通过LTE链路和NR链路传输数据包；
步骤704：当终端设备确定第一应用为预设的应用程序的时候，终端设备可以按照第二数据传输策略进行数据传输。
在一些实施例中，终端设备可以通过白名单的方式对特定的应用程序进行标识，例如，可以通过监听前台应用程序的包名或者活动activity。对于预设的应用程序，通常是时延要求或者丢包率要就较高的应用程序，用户在运行这些应用程序的时候，不希望出现卡顿等情况，典型的应用比如游戏应用、语音视频聊天 应用，或者有以下场景的应用：OTT(over-the-top)语音通话、对战游戏、DNS(Domain Name System)数据包等。
在一些实施例中，终端设备可以通过UUID(universally unique identifier)或者PID(process ID)来识别当前应用程序名。
在一些实施例中，第二数据传输策略是相对于第一数据传输策略的，第一数据传输策略是可以默认设置的，还可以是遵循现有的标准协议，而第二数据传输策略是需要终端设备使能该策略，并且在使能该策略之后，数据包通过低时延通道来进行发送。
在一些实施例中，低时延通道可以是具有第一优先级的通道，该通道的传输质量通常是优于另一通道，终端设备可以通过检测一些特定的条件或者参数来确定两条通道的优先级，例如可以实时或者周期性的检测来两条通道的时延、丢包率等参数，可以将传输的质量较好的通道设置为用于传输对时延比较敏感的数据的数据包。
在本申请实施例中，当检测到第一应用程序为预设的应用程序的时候，可以将数据包通过低延通道发送。具体如图8所示,示出了一种第二数据传输策略下数据发送示意图，即当数据包在PDCP层实体的时候，通过确定是第一应用程序的数据包或第二应用程序的数据包来确定通过低时延通道或者高时延通道来发送，具体地，可以通过低时延链路发送第一应用程序的数据包，而非第一应用程序的数据包可以通过高时延通道发送。
本申请实施例可以通过确定运行的应用程序从而选择双链接下的数据传输通道，相对传统的分流方式，传输的效率更好，更省功耗，用户的体验也更好。
如图9所示，本申请实施例还提供另一种分流数据的方法，以终端设备发送上行数据为例，可以根据终端设备当前所发送的数据包的类型来确定是否进行分流传输，具体的：
步骤901：终端设备确定发送第一数据包；
终端设备可以运行第一应用程序，第一应用程序可以是前台应用程序还可以是后台应用程序，还可以是多个应用程序同时运行，其中终端设备处于双连接的网络，即终端设备可以通过LTE链路和NR链路进行数据传输。
在一些实施例中，终端设备发送第一数据包，可以是终端设备接收到用户针对浏览器应用程序的搜索请求，还可以是接收到用户针对应用市场的下载请求。
步骤902：当终端设备确定第一数据包为非预设类型的数据包，执行步骤903；当终端确定所述第一数据包为预设数据包，可以执行步骤904.
在一些实施例中，可以通过数据包的包名来确定当前数据的类型。对于一些时延敏感的数据包类型，可以进行通过打标签的方式进行标识，常见的例如：OTT语音通话数据包、对战游戏数据包、DNS数据包等。
步骤903：当终端设备确定第一数据包的类型为非预设数据包类型的时候，可以按照第一传输策略来进行传输。所述第一传输策略可以如步骤703相同。
步骤904：当终端设备确定第一数据包的类型为预设数据包的类型的时候， 终端设备通过第二传输策略来进行传输，所述第二传输策略可以步骤704相同。具体如图10所示,示出了一种第二策略下数据发送示意图，既可以通过低时延通道发送DNS数据包。
在一些实施例中，还可以直接通过硬件资源的占用情况来确定数据包是从低时延通道还是高时延通道，例如，当终端设备调用了麦克风和摄像头时，可以认为终端设备需要发送语音包，即可以通过低时延通道来发送。
本申请实施例相对于图7所的所示的实施例，本实施例通过数据包的类型进行策略的调整，能够更加的精确。传输的效率更好，更省功耗，用户的体验也更好。
如图11所示，本申请实施例还提供一种新的分流数据的方法，结合终端设备的状态以及待发送数据包的类型进行分流策略的选择，具体地：
步骤1101：终端设备运行第一应用程序，步骤可以同步骤701；
步骤1102：终端设备确定当前运行的第一应用程序是为预设应用程序，则执行步骤11053,当终端设备确定运行的第一应用程序为非预设应用程序时，则执行步骤1104；
判断当前运行的第一应用程序的方法可以同步骤704：
步骤1103：当终端设备确定当前运行的第一应用程序是为预设应用程序时，进一步确认当前第一应用程序下的数据包是否为预设类型的数据包，当确认所述第一数据包为预设类型的数据包时，执行步骤1105；当所述第一数据包为非预设类型的数据包的时候，执行步骤1104。
在一些实施例中，确定第一数据包的类型是否为预设数据包的方法可以同步骤703；
在一些实施例中，由于步骤1102中已经确认了当前运行的应用程序，还可以根据第一应用程序上报的状态来决定是否启用步骤1105，例如，一些游戏应用程序可以分为登录状态、对战状态，当检测到第一应用程序为预设的应用程序，并且为预设的状态下，则可以执行1105，通常来讲，在对战状态下，用户对数据的时延要求更高。终端可以通过API接口获取当前应用程序的状态。
在一些实施例中，还可以结合当前终端设备的其他状态来确定是否启用第二传输策略，比如，麦克风是否长期处于开启状态，摄像头是否启动等，当用户的麦克风或者摄像头长期处于开启的状态，可以认为用户在进行语音数据包或者视频数据包的传输，而上述包对时延的要求较高，可以采用第二传输策略。
在一些实施例中，还可以通过端口号来判断当前的数据的类型，例如，当端口号为53的时候，可以确定当前传输的DNS数据包。
在一些实施例中，当确定应用程序已经包名来确定是否确定第二传输策略，例如，当微信在前台运行的时候，并且发送UDP数据包时候，确定终端设备当前在语音或者视频通话。
步骤1104：当确定第一数据包类型为非第一应用程序的预设类型的数据包，或者预设的状态，可以执行步骤1104。
终端设备可以采用第一传输策略，可以同步骤703。
步骤1105：当确定第一数据包为预设类型的数据包，可以进行第二传输策略。
第二传输策略可以同步骤704。
本申请实施例中，终端设备通过确定预设的应用程序类型，在结合数据包类型或者硬件资源占用的情况，确定特定应用程序的特定数据包采用上行分流的传输策略，即将对时延比较敏感的数据包通过低时延通道进行数据传输。
值得说明的是，本申请还提供一种新的数据传输方法，通过判断第一应用程序是否为预设应用程序，决定是否启动第三传输策略的方法，如图12所示：
步骤1201-1203：可以参考步骤701-703的方法；
步骤1204：当确定第一应用程序为预设应用程序的时候，可以采用第三传输策略进行数据发送。
在一些实施例中，第三传输策略可以是自主复制数据包(Duplication)的方法，即当确定应用程序为预设应用程序的时候，在发送数据包的时候，终端设备自主的将待发送的数据复制为两份，并分别通过LTE链路和NR链路发送到网络设备。
在一些实施例中，一些对数据时延要求较高的场景或者数据包如下，具体地，以游戏应用程序为例，可以将游戏分为不同的状态，例如对战状态以及登录状态，通常情况下，用户在对战状态下对时延的要求较高。又比如，用户在通过第三方APP进行语音或者视频通过的时候，终端设备先确定当前前台运行的应用程序是否为预设的应用程序，预设的应用程序可以通过白名单的方式进行设置，还可以是基于用户手动添加的，当确定前台的应用程序是预设的应用程序的时候，进一步通过硬件资源占用的情况确定是否为语音或者视频的状态，例如，可以通过判断MIC或者扬声器的占用情况，进一步，如果用户通过蓝牙连接其他的设备，还可以通过外设的MIC等使用情况来判断。
Figure PCTCN2021081412-appb-000002
上述场景如果检测到卡顿后下发modem数据包启动从低时延通道发送，如果网侧不配置辅通道，可以自主启动辅通道传输。
为了加快接收侧的数据包向上递交，减缓因其中一个链路上迟迟不能完成的 重传，就需要将将一些稀疏的未能成功传输的数据包在另一个链路上进行同步传输，加速接收侧PDCP接收到的概率，如图13所示，示出了一种基于第三传输策略的数据流传输示意图，数据在PDCP层复制之后，将数据分别发送到LTE链路和NR链路上，且两条链路产生的时延可能有不同，网络侧可以两条链路的时延来确定丢弃那一条链路的数据包。
如图13所示，MCG：Master Cell group，主小区组，SCG：Secondary Cell group，辅小区组，可以简单理解为UE首先发起随机接入(RACH)的Cell所在的Group就是MCG。如果没有进行双链接，也就没有MCG和SCG的概念。或者也可以理解为，如果没有进行双链接，那么该小区组就对应MCG。
本申请实施例对于特定的时延敏感业务需要主动包复制发送，需要依赖于网侧重复包删除技术删除重复包，网络设备会收到两份数据包，传输时延较大的一侧数据包被正常丢弃。
在EN-DC场景下，充分利用LTE和NR的带宽资源。通过自主包复制减少NR弱覆盖场景的ENDC不满足分流门限，不向辅路径分流引入的卡顿问题，当某些数据包不能发送成功时，网路侧PDCP层需要持续等待相应数据包，阻塞其他数据包的向上递交。当数据包在RLC层传输时，按现有协议必须要收到接收侧的ACK，这个数据包传输才算完成。基于EN-DC分流的特点，数据包在两条传输路径分别发送，如果因为传输路径异常引起其中一个路径的数据包发送时延大，则影响整体速率。因此，通过包复制的数据传输策略Duplication提高两条路径的传输可靠性。
本方案的退出条件是应用在低时延通道上卡顿，或者前台应用切后台。根据前台应用自主吐出的卡顿信息或者前台应用的RTT检测实现卡顿检测。
本申请还提供一种新的数据传输方法，通过判断第一应用程序是否为预设类型的数据包，决定是否启动第三传输策略的方法，如图14所示：
步骤1401-1403：步骤可以同901-903；
步骤1404：当终端设备确定第一数据包为预设的数据包类型的时候，可以通过复制包的方法进行数据传输，方法可以同步骤1204所述的方法。
本申请还提供一种新的数据传输方法，通过结合应用程序以及数据包的类型决定是否启动第三传输策略的方法，如图15所示：
步骤1501-1504：可以同步骤1101-1104；
步骤1105：当确定第一数据包的类型为预设数据包类型的时候，可以采用第三传输策略进行传输，如步骤1204的方法。如图16所示，可以将数据包通过复制的方式进行两个通道的同步传输。
在一些实施例中，确定第一数据包的类型是否为预设数据包的方法可以同步骤703；
在一些实施例中，由于步骤1102中已经确认了当前运行的应用程序，还可以根据第一应用程序上报的状态来决定是否启用步骤1105，例如，一些游戏应用程序可以分为登录状态、对战状态，当检测到第一应用程序为预设的应用程序， 并且为预设的状态下，则可以执行1105，通常来讲，在对战状态下，用户对数据的时延要求更高。终端可以通过API接口获取当前应用程序的状态。
在一些实施例中，还可以结合当前终端设备的其他状态来确定是否启用第三传输策略，比如，麦克风是否长期处于开启状态，摄像头是否启动等，当用户的麦克风或者摄像头长期处于开启的状态，可以认为用户在进行语音数据包或者视频数据包的传输，而上述包对时延的要求较高，可以采用第三传输策略。
在一些实施例中，还可以通过端口号来判断当前的数据的类型，例如，当端口号为53的时候，可以确定当前传输的DNS数据包。
在一些实施例中，当确定应用程序已经包名来确定是否确定第三传输策略，例如，当微信在前台运行的时候，并且发送UDP数据包时候，确定终端设备当前在语音或者视频通话。
本申请实施例终端设备通过确定预设的应用程序类型，在结合数据包类型或者硬件资源占用的情况，确定特定应用程序的特定数据包采用复制的方法进行传输，这样大大的提升的传输的效率。
本申请实施例还提供一种实现上述实施例的终端设备的架构示意图，如图17所示：可以将终端设备的软件架构包括为应用层、RIL层、kernel内核层、modern侧。
应用层包括识别模块，所述识别模块主要用于识别当前的应用程序，监听应用的包名或者活动activity。
在一些实施例中，还可以监听一些物理资源的占用情况，例如Mic或者摄像头，一种可能的场景：微信的语音场景需要启动自主包复制传输。检测逻辑为相应的activity在前台，且麦克接口长时间处于启动状态，摄像头未启动，则需要进行上述实施例所述的自主包复制传输。
在一些实施例中，还可以监听外设的连接情况，比如蓝牙耳机、手表、手环等连接情况，例如，通过检测蓝牙耳机连接以及摄像头开启，则启动包复制功能传输数据包。
在一些实施例中，还可以监听应用程序的状态，例如游戏应用程序的对战状态启动包复制功能。
RIL层为应用层与物理层的接口层，主要用于控制面数据的传输。
内核层包括主要用于上行包复制策略的配置，例如可以通过标识位来使能该传输策略。由于应用层通常仅能识别出应用或者活动的类型，对于应用相关的数据包类型通常不能识别，这时候需要内核层来进行包类型识别，并且相应的数据包进行打标签，例如，可以通过ock结构体的acc_stat字段去定义，当将该字段中的任一位为1时，可以该数据包需要启动包复制传输或者分流传输，且该字段随数据包发送至modem。
在一些实施例中，内核层中可以存储有预设应用的标识或者数据包的标识，当应用层识别出前台应用为预设应用程序的时候，会发送指令至内核层，启动包复制数据传输。
在一些实施例中，当前台应用切换为非预设应用程序的时候，应用层还发送指令，去使能包复制功能，例如，可以通过ock结构体的acc_stat字段去定义，当将该字段中的任一位设置为0时。
在一些实施中，内核层中可以存储有预设应用程序和或预设数据包的类型的对应关系，以下表为例：
应用程序名 数据包类型 是否启动
A应用程序 语音数据包 是
A应用程序 图片数据包 否
B应用程序 图片数据包 否
内核层根据应用层的操作进行确定待发送的包是否启动包复制或者分流策略，当接收到应用层的发送的数据包，解析数据包中的应用程序名称，进一步判断数据包的类型。
Modem侧：主要用于执行该策略，Modem按照上层的条件给出是否启动包复制传输，从包中解析是否支持自主包复制传输，即可以通过acc_stat字段中的标识位。
在一些实施例中，Modem监测数据包在两个路径的传输情况，如果其中路径上长时间未能成功传输时，或者PDCP缓存数据包超过一定时间阈值；PDCP启动包复制duplication方式处理数据包。
上述框架同样适用第二传输策略分流策略的执行。具体如图18所示：
步骤1801：应用层读取配置文件，识别当前是否满足预设的条件。
具体地，可以应用层中包括一个APK,可以通过该APK实现监听当前应用程序的状态，当确定当前运行的应用程序为预设的应用程序的时候，可以发送指令至内核层。
步骤1802：当满足条件时使能包复制功能策略。
确定当前运行的应用程序为预设的应用程序的时候，可以发送指令至内核层，该指令用于使能包复制传输策略。
步骤1803：内核层启动包复制规则。
如图17所示的描述，内核层包括主要用于上行包复制策略的配置，例如可以通过标识位来使能该传输策略。
步骤1804:给待发送的数据打标签进行发送至modem侧。
本申请实施例还提供一种下行数据传输的方法，相对于上行数据的分流或者复制传输，下行数据接收，终端设备的PDCP层接收到来自LTE链路和NR链路的数据，进行汇聚，发送给上层，如图所述19所示，终端设备收到来自LTE通道的数据包，例如，DNS数据包1，游戏包1，图片包1；还接收到来自NR通道的图片数据包2，以及DNS数据包2，游戏数据包2，当终端设备通过数据包的类型识别到DNS数据包和游戏数据包为时延较为敏感的数据包，则将这个数据包放置在非乱序重拍缓冲区，直接发送至上层应用，而如果是非延时的数据包，例如图片数据包等，则进入乱序重拍缓冲区，该重排缓冲区的特点是需要等 待预定时间或者预定数量、大小的数据包达到阈值之后才一起发送给上层应用。
例如下载图片的场景，DNS解析的响应，以及游戏数据包等要求实时响应的数据包的被放到与图片的数据包下载一起乱序重组，导致游戏数据包延迟，DNS解析变慢等问题。LTE和NR的两个通道中，其中一个通道数据包发生延迟将引起整体数传延迟，因此本发明需要集中对容忍乱序业务数据包(例如DNS数据包、游戏数据包、语音通话数据包、直播数据流、混合业务场景等)采用乱序提交的方案。
下行区分时延敏感业务和非时延敏感业务，将游戏和DNS等时延敏感业务不进行乱序重排或者小定时的乱序重排，其他按照时延敏感值设置乱序重排定时器。根据TCP协议栈的RTO的值动态调整下行乱序重排序定时器时长。
方案原理是当下行发生ENDC分流场景识别下行数据包的类型和上层业务类型，部分数据包支持乱序提交，在ENDC存在丢包场景不因为下行乱序重排序对于正常到达的数据包延迟提交。
本申请实施例还提供一种实现上述实施例的终端设备的架构示意图，如图17所示：可以将终端设备的软件架构包括为应用层、RIL层、kernel内核层、modern侧。
涉及到4种流程：初始化、启动下行乱序提交、停止下行乱序提交、
初始化是依据输入配置的json文件获取需要启动自主下行乱序提交的包名和activity名，应用层包括识别模块，所述识别模块主要用于识别当前的的应用程序，监听应用的包名或者活动activity。
在一些实施例中，还可以监听一些物理器件，例如Mic或者摄像头，一种可能的场景：微信的语音场景需要启动自主包复制传输。检测逻辑为相应的activity在前台，且麦克接口长时间处于启动状态，摄像头未启动，则需要进行上述实施例所述的乱序提交。
满足下行乱序提交的场景下发modem启动乱序提交，这里一般是指UDP包。
Modem按照上层的条件给出是否下行乱序重排，仅在NPDCP乱序重排序场景生效，具体地：从包中解析是否支持自主包复制传输；从AT命令中获取是否对UDP包(其中一个条件)启动乱序提交。具体如图20所示：
步骤2001：读取配置文件，当满足预设条件时，下发乱序提交规则；
读取配置文件，用于识别当前前台运行的应用程序，具体步骤如703，当确定当前运行的应用程序为预设的应用程序时，发送控制命令至RIL层；
步骤2003：RIL层接收到指令用，发送启动乱序提交规则至modem层。
