具体实施方式
下面结合附图，对本申请的实施例进行描述，显然，所描述的实施例仅仅是本申请一部分的实施例，而不是全部的实施例。本领域普通技术人员可知，随着技术的发展和新场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请实施例提供一种数据量整形方法、网络设备及存储介质，通过设定数据容量门限、时间门限以及判断条件，解决第五代移动通信(the 5th Generationmobile communication technology，5G)中分组数据汇聚层协议(packet data convergence protocol，PDCP)层或者长期演进(long term evolution，LTE)***无线链路控制(radio link control，RLC)收到下层数据包后可能产生的瞬时流量突发的问题，达到降低瞬时出口速率的目的。以下分别进行详细说明。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或模块的过程、方法、***、产品或设备不必限于清楚地列出的那些步骤或模块，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或模块。在本申请中出现的对步骤进行的命名或者编号，并不意味着必须按照命名或者编号所指示的时间/逻辑先后顺序执行方法流程中的步骤，已经命名或者编号的流程步骤可以根据要实现的技术目的变更执行次序，只要能达到相同或者相类似的技术效果即可。本申请中所出现的模块的划分，是一种逻辑上的划分，实际应用中实现时可以有另外的划分方式，例如多个模块可以结合成或集成在另一个***中，或一些特征可以忽略，或不执行，另外，所显示的或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些端口，模块之间的间接耦合或通信连接可以是电性或其他类似的形式，本申请中均不作限定。并且，作为分离部件说明的模块或子模块可以是也可以不是物理上的分离，可以是也可以不是物理模块，或者可以分布到多个电路模块中，可以根据实际的需要选择其中的部分或全部模块来实现本申请方案的目的。
需要说明的是，本申请实施例中，名词“网络”和“***”经常交替使用，但本领域的技术人员可以理解其含义。信息(information)，信号(signal)，消息(message)有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是一致的。
应理解，本申请提到的网络设备可以是任意一种具有无线收发功能的设备或可设置于该设备的芯片，该设备包括但不限于：基站、演进型基站(evolved node B，eNB)、家庭基站、无线保真(wireless fidelity，WIFI)***中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为NR***中的gNB，或者，还可以是构成基站的组件或一部分设备，如汇聚单元(central unit，CU)、分布式单元(distributedunit，DU)或基带单元(baseband unit，BBU)等。应理解，本申请的实施例中，对无线接入网设备所采用的具体技术和具体设备形态不做限定。在本申请中，无线接入网设备简称网络设备，如果无特殊说明，在本申请中，网络设备均指无线接入网设备。在本申请中，网络设备可以是指网络设备本身，也可以是应用于网络设备中完成无线通信处理功能的芯片。
在一些部署中，gNB可以包括CU和DU。gNB还可以包括射频单元(radio unit，RU)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU实现无线资源控制(radio  resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能，DU实现无线链路控制(radio link control，RLC)、媒体接入控制(media access control，MAC)和物理(physical，PHY)层的功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令或PHCP层信令，也可以认为是由DU发送的，或者，由DU+RU发送的。可以理解的是，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外，CU可以划分为接入网RAN中的网络设备，也可以将CU划分为核心网CN中的网络设备，在此不做限制。
还应理解，本申请提到的终端设备也可以称为终端、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等。本申请实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑，还可以是应用于虚拟现实(virtual reality，VR)、增强现实(augmented reality，AR)、工业控制(industrial control)、无人驾驶(self driving)、远程医疗(remote medical)、智能电网(smart grid)、运输安全(transportation safety)、智慧城市(smart city)以及智慧家庭(smart home)等场景中的无线终端。本申请中将前述终端设备及可应用于前述终端设备的芯片统称为终端设备。应理解，本申请实施例对终端设备所采用的具体技术和具体设备形态不做限定。
通常在5G通信***或者LTE通信***中具有如图1所示的无线接口协议栈。如图1所示，在发送端和接收端该无线接口协议栈均包括分组数据汇聚协议(packet data convergence protocol，PDCP)层、无线链路层控制协议(radio linkcontrol，RLC)层、媒体介入控制(media access control，MAC)层和物理层(physicallayer，PHY)层。其中PHY层位于协议栈的最底层，也被称为层一。PHY层之上的层被称为层二。层二的用户平面协议栈架构又被进一步分为三个子层，从低到高分别是MAC子层、RLC子层和PDCP子层。图1以终端设备为发送端，接入网设备为接收端为例。数据包依次从终端设备的PDCP层传输至RLC层，再由RLC层传输至MAC层，再由MAC层传输至PHY层，最后在空口发送至接入网设备。接入网设备为发送端，终端设备为接收端同理。具体的，对于每一个子层来说，来自更高一子层的信息单元被称为该子层的服务数据单元(service data unit，SDU)，而经过该子层处理后送往下一子层的信息单元，被称为该子层的协议数据单元(protocol data unit，PDU)。PDCP子层会将从高层来的数据包分配序列号(serial number，SN)，经过头压缩、加密、完整性保护、加包头等操作形成数据PDU，发送至RLC子层,比如，PDCP子层可以将从网际协议(internet protocol，IP)层接收到的IP包分配SN,经过头压缩、加密、完整性保护、加包头等操作形成数据PDU，发送至RLC子层。RCL子层在收到PDCP子层的PDU之后，会对接收到的多个PDU或PDU分段进行级联后仅分配一个SN号，在添加RLC包头后形成RLC数据PDU，以下将PDU和SDU统一简称为“数据包”、“数据块”或者“包”，但是本领域技术人员应当理解，在不同的场景下，数据包、数据块或者包代表PDU还是SDU。
但是，在时分双工(time division duplex，TDD)模式的移动通信***中，网络设备通过MAC层分配给上行的时域资源少，当空口产生重传后，如选择按序递交，PDCP层需要 等待重传的包，具体的，在不同的通信***中可能由不同的协议架构层等待重传的包，比如在LTE***中，可能是RLC层等待重传的包，随着技术的发展，可能由其他主体执行等待重传的包，本申请实施例并不对执行等待重传的包的主体进行限定，这可能导致PDCP层或者RLC层的突发数据流量大大增加，进而传输网络丢包的概率增加。为了清楚的说明这一问题，下面结合图表进行说明。
表1给出了一种现有的LTE TDD***中上下行时域资源的配比。如表1所示，其中D代表网络设备通过MAC层配置的下行时域资源，U代表网络设备通过MAC层配置的上行时域资源，其中，上下行配置序号5的上下行时频资源的配比为1比9。表2给出了一种现有的5G TDD***中上下行时域资源的配比。如表2所示，其中D代表网络设备通过MAC层配置的下行时域资源，U代表网络设备通过MAC层配置的上行时域资源，其中，上下行配置序号0的上下行时频资源的配比为2比8，由表1和表2可以看出，无论是在LTE TDD***还是5G TDD***中，网络设备通过MAC层分配给上行的时域资源都很少。

网络设备通过MAC层分配给上行的时域资源都很少，这可能导致PDCP层或者RLC层的突发数据流量大大增加，进而传输网络丢包的概率增加，下面结合表3和表4，以5G通信***为例进行说明。表3是一种5G通信***中的帧结构，假设入口速率为40Mbps，毫秒级发包均匀，每个slot发送4个包，上下行slot的配比为1:4，在本申请中，入口速率可以指终端设备的RLC层到MAC层的速率，则前4个slot的上行数据包需要在第5个slot进行传输，那么实际上，上行每个slot需要发送20个数据包，在第5个slot的速率可以达到200Mbps，即出口速率为200Mbps，在本申请中，出口速率可以指网络设备的 MAC层到RLC层的速率。当空口产生重传后，如选择按序递交，则PDCP层需要等待重传的包，此时的PDCP层的突发数据量将更大，下面结合表4进行说明。表4给出了一种PDCP层重排序并按序递交的流程。如表格4所示，假设在帧号n的slot4，终端设备通过MAC层发送了一个数据块1(DATA1)，且网络设备侧的MAC层没有正确接收，在帧号n的slot9、slot14、slot19，终端设备通过MAC层分别发送了数据块2(DATA2)、数据块3(DATA3)以及数据块4(DATA4)，且DATA2、DATA3以及DATA4均被网络设备侧的MAC层正确接收。DATA2、DATA3以及DATA4依次从网络设备的MAC层传输至RLC层，再由RLC层传输至PDCP层，PDCP层需要对DATA1、DATA2、DATA3以及DATA4进行排序后在向高层发送，但是由于DATA1未被正确接收，DATA2、DATA3以及DATA4将一直缓存在PDCP层，直到DATA1被正确接收。假设帧号n+1的slot4，终端设备通过MAC层重新发送DATA1，且网络设备的MAC层正确接收了DATA1，则网络设备侧的PDCP层对DATA1、DATA2、DATA3以及DATA4进行排序后一并发送给高层，需要解释的是，帧号n+1的slot4，还需要发送帧号n+1的前4个slot的上行数据包，并且如果帧号n+1的slot4，DATA1仍然没有传对，则继续重传，PDCP层会一直等待重排，这可能导致突发流量或者突发速率更大。

数据量整形是提高数据传输效率和质量、减少甚至避免丢包、优化业务传输性能、提升用户感知的重要手段，数据量整形通常使用缓冲区和令牌桶来完成，当报文的发送速度过快时，首先在缓冲区进行缓存，在令牌桶的控制下再均匀地发送这些被缓冲的报文。但是，现有技术只规定了传输网络的IP层的数据量整形，没有规定5G网络设备侧的PDCP层和4G网络设备侧的RLC层的数据量整形方案。现有的流量数据量整形方案会导致数据包经过MAC层后，在PDCP层或者RLC层突发流量大，进而对于传输网络的冲击较大，换句话说，现有技术在传输网络的IP层的数据量整形并不能改善PDCP层或者RLC层突发数据量大的问题，这会导致网络利用率低，另外会导致传输网络出现丢包或者时延的问题。
为了解决上述技术问题，本申请实施例提供一种数据量整形方法，以下进行详细的说明。
图2为本申请实施例提供的一种数据量整形方法的流程示意图。
如图2所示，本申请实施例提供的一种数据量整形方法，可以包括如下步骤：
201、网络设备通过整形层获取终端设备发送的N个数据包。
网络设备通过整形层获取终端设备发送的N个数据包，N为大于0的整数。当空口产生重传后，如选择按序递交，则N个数据包按序递交，整形层用于对N个数据包进行排序。
202、网络设备将N个数据包的数据量或整形层发送数据包的时间间隔与预设值比较。
网络设备确定N个数据包没有丢失或者确定N个数据包没有乱序时，网络设备将N个数据包的数据量或整形层发送数据包的时间间隔与预设值比较。示例性的，网络设备预先设定的预设值包括第一预设值和第二预设值，其中，第一预设值可以是容量门限，第二预设值可以是时间门限。示例性的，容量门限可以设置为传输网络的最小带宽在1个slot或者1个子帧内传输的数据量。时间门限可以设置为非连续上行时隙或者子帧的间隔。需要说明的是，时隙和子帧只是一种时间单位，本申请实施例并不对时间单位进行限制，本申请实施例为了清楚的说明方案，以时隙和子帧为例进行说明，以下对此不再重复赘述。
203、网络设备根据比较结果，通过整形层对数据量进行整形。
网络设备可以根据N个数据包的数据量与第一预设值的比较结果，或者整形层发送数据包的时间间隔与第二预设值的比较结果，通过整形层对数据量进行整形。
由图2对应的实施例可知，网络设备通过将N个数据包的数据量或整形层发送数据包的时间间隔与预设值比较，并且根据比较结果，通过整形层对数据量进行整形。在5G通信***中，整形层可以是PDCP层，在LTE通信***中，整形层可以是RLC层，此外，网络设备根据不同的比较结果，可以通过整形层对数据量进行不同的整形，下面将针对整形层对 数据量进行不同的整形进行具体的说明。
图3为本申请实施例提供的一种数据量整形方法的流程示意图。
如图3所示，本申请实施例提供的一种数据量整形方法，可以包括如下步骤：
301、网络设备通过整形层获取终端设备发送的N个数据包。
步骤301可以参阅图2对应的实施例中的步骤201进行理解，此处不再重复赘述。
302、网络设备判断N个数据包的数据量或整形层发送数据包的时间间隔是否达到预设值。
在一个具体的实施方式中，网络设备判断N个数据包的数据量是否达到第一预设值。其中，第一预设值可以是容量门限。示例性的，容量门限可以设置为传输网络的最小带宽在1个slot内传输的数据量，或者容量门限可以设置为传输网络的最小带宽在1个子帧内传输的数据量。
在一个具体的实施方式中，网络设备判断整形层发送数据包的时间间隔是否达到第二预设值。第二预设值可以是时间门限，示例性的，时间门限可以设置为非连续上行时隙或者子帧的间隔。
303、网络设备在当前的时间通过整形层向传输网络发送M个数据包。
在一个具体的实施方式中，若达到第一预设值，网络设备在当前的时间通过整形层向传输网络发送M个数据包，M个数据包的数据量向上取整为第一预设值。
在一个具体的实施方式中，若达到第二预设值，网络设备在当前的时间通过整形层向传输网络发送M个数据包，M个数据包的数据量向上取整为第一预设值。
下面分别以整形层为PDCP层和RLC层为例进行说明。
如图4所示，为本申请实施例提供的一种PDCP层数据量整形过程的示意图。
假设在slot4时，终端设备发送了DATA1，但是网络设备侧并没有接收到，在slot9、slot14、slot19时，终端设备分别发送了DATA2、DATA3以及DATA4，网络设备侧接收到并由RLC层发送到PDCP层。在5G通信***中，PDCP层对DATA1、DATA2、DATA3以及DATA4进行排序后，可以将这4个数据包发送到高层，举例说明，假设在下一个slot4，终端设备重发了DATA1，且网络设备侧接收到并由RLC层发送到PDCP层，则PDCP层在下一个slot4对DATA1、DATA2、DATA3以及DATA4进行排序后，可以将这4个数据包发送到高层。
在一个具体的实施方式中，当PDCP层对DATA1、DATA2、DATA3以及DATA4进行排序后，如果网络设备通过PDCP层确定这4个数据包的数据量不小于第一预设值，网络设备确定在当前的slot内通过PDCP层发送M个数据包的数据量，M个数据包的数据量向上取整为第一预设值。换句话说，在当前的slot内发送能够允许发送的最大数据量。超过第一预设值的数据量放入PDCP层的缓存，在后续的slot内继续发送剩余的数据量，剩余的数据量为4个数据包的数据量与第一预设值的差值。
在一个具体的实施方式中，当PDCP层对DATA1、DATA2、DATA3以及DATA4进行排序后，确定PDCP层的发送数据包的时间间隔不小于第二预设值，网络设备确定在当前的slot内通过PDCP层发送M个数据包的数据量，M个数据包的数据量向上取整为第一预设值。换句话说，在当前的slot内发送能够允许发送的最大数据量。超过第一预设值的数据量放入 PDCP层的缓存，在后续的slot内继续发送剩余的数据量，剩余的数据量为4个数据包的数据量与第一预设值的差值。
如图5所示，为本申请实施例提供的一种RLC层数据量整形过程的示意图。
假设在子帧4时，终端设备发送了DATA1，但是网络设备侧并没有接收到，在子帧9、子帧14、子帧19时，终端设备分别发送了DATA2、DATA3以及DATA4，网络设备侧接收到并由MAC层发送到RLC层。在LTE通信***中，RLC层对DATA1、DATA2、DATA3以及DATA4进行排序后，可以将这4个数据包发送到高层。
在一个具体的实施方式中，当RLC层对DATA1、DATA2、DATA3以及DATA4进行排序后，如果网络设备通过RLC层确定这4个数据包的数据量不小于第一预设值，网络设备确定在当前的子帧内通过RLC层发送M个数据包的数据量，M个数据包的数据量向上取整为第一预设值。换句话说，在当前的子帧内发送能够允许发送的最大数据量。超过第一预设值的数据量放入RLC层的缓存，在后续的子帧内继续发送剩余的数据量，剩余的数据量为4个数据包的数据量与第一预设值的差值。
在一个具体的实施方式中，当RLC层对DATA1、DATA2、DATA3以及DATA4进行排序后，确定RLC层的发送数据包的时间间隔不小于第二预设值，网络设备确定在当前的子帧内通过RLC层发送M个数据包的数据量，M个数据包的数据量向上取整为第一预设值。换句话说，在当前的子帧内发送能够允许发送的最大数据量。超过第一预设值的数据量放入RLC层的缓存，在后续的子帧内继续发送剩余的数据量，剩余的数据量为4个数据包的数据量与第一预设值的差值。
本申请图3对应的实施例，通过设定整形条件，对瞬时突发流量整形，降低突发速率。在达到预设值时，在当前的slot或者子帧内，整形层发送能够允许发送的最大数据量，减少传输网络丢包并且不引入过大时延，提升无线通信TDD***业务体验。
图6为本申请实施例提供的另一种数据量整形方法的流程示意图。
如图6所示，本申请实施例提供的另一种数据量整形方法，可以包括如下步骤：
601、网络设备通过整形层获取终端设备发送的N个数据包。
步骤601可以参阅图2对应的实施例中的步骤201进行理解，此处不再重复赘述。
602、网络设备判断N个数据包的数据量是否达到第一预设值，整形层发送数据包的时间间隔是否达到第二预设值。
网络设备判断N个数据包的数据量是否达到第一预设值，且判断整形层发送数据包的时间间隔是否达到第二预设值。第一预设值可以是容量门限，示例性的，容量门限可以设置为传输网络的最小带宽在1个slot内或者1个子帧传输的数据量。第二预设值可以是时间门限，示例性的，时间门限可以设置为非连续上行时隙或者子帧的间隔。
603、网络设备通过整形层在P个时间单元向传输网络发送N个数据包的数据量。
P为第二预设值与整形层发送数据包的时间间隔的比值。若N个数据包的数据量未达到第一预设值且整形层发送数据包的时间间隔未达到第二预设值，则网络设备通过整形层在P个时间单元向传输网络发送N个数据包的数据量，P为第二预设值与整形层发送数据包的时间间隔的比值。
在一个具体的实施方式中，网络设备通过整形层在P个时间单元向传输网络平均发送N个数据包的数据量。
下面分别以整形层为PDCP层和RLC层为例进行说明。
如图7所示，为本申请实施例提供的另一种PDCP层数据量整形过程的示意图。
假设在slot4时，终端设备发送了DATA1，并且网络设备侧正确接收到DATA1，并由RLC层发送到PDCP层。在5G通信***中，PDCP层确定接收到的数据包已经按序排好，可以将DATA1发送到高层。
若网络设备通过PDCP层确定DATA1的数据量未达到第一预设值且整形层发送数据包的时间间隔未达到第二预设值，网络设备通过整形层在P个时隙向传输网络发送N个数据包的数据量。P为第二预设值与整形层发送数据包的时间间隔的比值，结合图7进行说明，假设第二预设值为5个slot，整形层发送数据包的时间间隔为1个slot，则P为5，那么PDCP层收到DATA1后，在5个slot上发送DATA1的数据量，在一种具体的实施方式中，可以在5个slot上平均发包，在另一种具体的实施方式中，也可以在5个slot上不平均发包。如图7所示，为在5个slot上平均发送数据包的示意图。具体的，若DATA1的数据量未达到第一预设值且整形层发送数据包的时间间隔未达到第二预设值，则网络设备通过整形层在5个时隙向传输网络平均发送DATA1的数据量，如图7所示，在slot4，PDCP向高层发送数据量R1，其中R1是五分之一的DATA1的数据量，同时PDCP层缓存数据量R2、R3、R4以及R5，R2、R3、R4以及R5分别是五分之一的DATA1的数据量，R1、R2、R3、R4以及R5的总和为DATA1的数据量。在slot5，PDCP向高层发送数据量R2，同时PDCP层缓存数据量R3、R4以及R5。在slot6，PDCP向高层发送数据量R3，同时PDCP层缓存数据量R4和R5。在slot7，PDCP向高层发送数据量R4，同时PDCP层缓存数据量R5。在slot7，PDCP向高层发送数据量R5。
在一种具体的实施方式中，也可以通过其他方式确定P值，比如网络设备可以预先设定将数据量划分为P份，在图7的实施例中，即通过PDCP层将DATA1的数据量划分为P份，在实际应用过程中，可以按照需求设定P的数目。
如图8所示，为本申请实施例提供的另一种RLC层数据量整形过程的示意图。
假设在子帧4时，终端设备发送了DATA1，并且网络设备侧正确接收到DATA1，并由MAC层发送到RLC层。在LTE通信***中，RLC层确定接收到的数据包已经按序排好，可以将DATA1发送到高层。
若网络设备通过RLC层确定DATA1的数据量未达到第一预设值且整形层发送数据包的时间间隔未达到第二预设值，网络设备通过整形层在P个时隙向传输网络发送N个数据包的数据量。P为第二预设值与整形层发送数据包的时间间隔的比值，结合图8进行说明，假设第二预设值为5个子帧，整形层发送数据包的时间间隔为1个子帧，则P为5，那么RLC层收到DATA1后，在5个子帧上发送DATA1的数据量，在一种具体的实施方式中，可以在5个子帧上平均发包，在另一种具体的实施方式中，也可以在5个子帧上不平均发包。如图8所示，为在5个子帧上平均发送数据包的示意图。具体的，若DATA1的数据量未达到第一预设值且整形层发送数据包的时间间隔未达到第二预设值，则网络设备通过整形层 在5个时隙向传输网络平均发送DATA1的数据量，如图8所示，在子帧4，RLC向高层发送数据量R1，其中R1是五分之一的DATA1的数据量，同时RLC层缓存数据量R2、R3、R4以及R5，R2、R3、R4以及R5分别是五分之一的DATA1的数据量，R1、R2、R3、R4以及R5的总和为DATA1的数据量。在子帧5，RLC向高层发送数据量R2，同时RLC层缓存数据量R3、R4以及R5。在子帧6，RLC向高层发送数据量R3，同时RLC层缓存数据量R4和R5。在子帧7，RLC向高层发送数据量R4，同时RLC层缓存数据量R5。在子帧7，RLC向高层发送数据量R5。
在一种具体的实施方式中，也可以通过其他方式确定P值，比如网络设备可以预先设定将数据量划分为P份，在图8的实施例中，即通过RLC层将DATA1的数据量划分为P份，在实际应用过程中，可以按照需求设定P的数目。
本申请图6对应的实施例，在N个数据包的数据量未达到第一预设值且整形层发送数据包的时间间隔未达到第二预设值时，在P个时隙或者子帧向传输网络发送N个数据包的数据量，这样不会在一个时隙或者子帧发送大量的数据，针对多用户场景，本申请实施例可以显著提升网络的利用效率。
