背景技术

目前，上下行数据可以同时传输，通常上行传输速率比下行低很多，下行数据对应的上行TCP ACK数据包可能会被上行数据业务阻挡。这样就会导致TCP ACK数据包延迟发送，进一步地，会导致下行数据的传输速率降低。

需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在 涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素，此外，本申请不同实施例中具有同样命名的部件、特征、要素可能具有相同含义，也可能具有不同含义，其具体含义需以其在该具体实施例中的解释或者进一步结合该具体实施例中上下文进行确定。
应当理解，尽管在本文可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本文范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语"如果"可以被解释成为"在……时"或"当……时"或"响应于确定"。再者，如同在本文中所使用的，单数形式“一”、“一个”和“该”旨在也包括复数形式，除非上下文中有相反的指示。应当进一步理解，术语“包含”、“包括”表明存在所述的特征、步骤、操作、元件、组件、项目、种类、和/或组，但不排除一个或多个其他特征、步骤、操作、元件、组件、项目、种类、和/或组的存在、出现或添加。此处使用的术语“或”和“和/或”被解释为包括性的，或意味着任一个或任何组合。因此，“A、B或C”或者“A、B和/或C”意味着“以下任一个：A；B；C；A和B；A和C；B和C；A、B和C”。仅当元件、功能、步骤或操作的组合在某些方式下内在地互相排斥时，才会出现该定义的例外。
为了能够更好地理解本申请实施例，下面对本申请实施例涉及的专业术语进行介绍：
传输控制协议(Transmission Control Protocol，TCP)：是一种面向连接的、可靠的、基于字节流的传输层通信协议。TCP旨在适应支持多网络应用的分层协议层次结构。连接到不同但互连的计算机通信网络的主计算机中的成对进程之间依靠TCP提供可靠的通信服务。
分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)：PDCP层属于无线接口协议栈的第二层，处理控制平面上的无线资源管理(Radio  Resource Control，RRC)消息以及用户平面上的因特网协议(IP)包。在用户平面上，PDCP子层得到来自上层的IP数据分组后，可以对IP数据分组进行头压缩和加密，然后递交到无线链路控制协议(RLC)子层。PDCP子层还向上层提供按序提交和重复分组检测功能。在控制平面，PDCP子层为上层RRC提供信令传输服务，并实现RRC信令的加密和一致性保护，以及在反方向上实现RRC信令的解密和一致性检查。PDCP实体位于PDCP层。对于一个终端设备，可以定义多个PDCP实体。每个用于携带用户平面数据的PDCP实体可以配置使用头压缩技术，每个PDCP实体携带一个无线承载的数据。
TCP报文到达确认(Acknowledge，ACK)：是对接收到的数据的最高序列号的确认，并向发送端返回一个下次接收时期望的TCP数据包的序列号(Ack Number)。例如，终端设备发送的当前数据序号是400，数据长度是100，则接入网设备收到后会返回一个确认号是501的确认号给终端设备。TCPACK的结构可以如图1所示，确认号占用32位，终端设备和接入网设备都可以发送，Ack＝Seq+1，其中该Seq即序列号，且是下行数据的序列号，并非本申请实施例中的序列号。需要说明的是，在本申请实施例中，TCP ACK可以是一个专用于回复确认号ACK的数据包，也可以是在一个携带其他数据的TCP数据包，该携带其他数据的TCP数据包中添加有ACK的信息。
序列号(Sequence Number，SN)：在PDCP实体中，SN编号可以是数据包的发送序列号，PDCP层可以根据每个数据包的SN编号来发送每个数据包。这样，接入网设备或终端设备中的接收方就可以保证顺序提交或检测重复的数据包。需要说明的是，SN编号存在一个最大值，该最大值是根据相关的协议确定的，当SN编号达到最大值后，该达到最大值的SN编号的下一个SN编号将会从0开始重新排列。例如，若该最大值为2 32-1，那么SN编号为2 32-1的下一个SN编号则为0。在本申请实施例中，涉及到对SN编号的加减运算，均满足该运算法则。
为了能够更好地理解本申请实施例，下面对本申请实施例可应用的网络架构进行说明。
请参见图2，图2为本申请实施例提供了一种无线通信网络的架构示意图。 该无线通信网络架构中包括终端设备和接入网设备。接入网设备可以部署服务小区，服务小区的个数可以是一个或一个以上，本申请实施例以服务小区为一个为例。在服务小区中可以分布多种信道，以传输不同的业务。终端设备和接入网设备都可以包括各自的PDCP实体，PDCP实体位于PDCP层中，终端设备和接入网设备可以通过PDCP实体进行IP包头压缩与解压缩、数据与信令的加密和解密，以及信令的完整性保护等操作。PDCP实体可以对PDCP层中的数据进行处理，这些数据可以是数据分组，即数据包，这些数据包可以来自该设备的中高层，如IP层等。PDCP实体可以将中高层发送过来的数据包进行编号处理，即给每个数据包分配一个SN编号，然后根据各个数据包的SN编号分别发送各个数据包。如图3所示为一种无线通信的数据流向示意图，终端设备的PDCP实体可以接收终端设备的网络层，即中高层发送的数据，PDCP实体处理完该数据后，可以将其发送给RLC实体，RLC层再对PDCP实体发送的数据进行处理并发送给MAC实体，以此类推。当接入网设备的物理层接收到终端设备的物理层发送的信息后，可以对该信息进行解调、解码等操作，逐步发送至接入网设备的PCDP实体、网络层等。这样就实现了无线通信的数据交换。
需要说明的是，在本申请实施例中，每个协议层均可以对应有各自的实体，例如，RLC层对应RLC实体。各协议层对应的实体所执行的步骤在该协议层中完成。例如，PDCP实体所执行的步骤在PDCP层中完成。
本申请实施例中所涉及的接入网设备，是网络侧的一种用于发射或接收信号的实体，可以用于将收到的空中帧与网络协议(internet protocol，IP)分组进行相互转换，作为终端设备与接入网的其余部分之间的路由器，其中接入网的其余部分可以包括IP网络等。接入网设备还可以协调对空中接口的属性管理。例如，接入网设备可以是LTE中的演进型基站(evolutional Node B，eNB或e-NodeB)，还可以是新无线控制器(new radio controller，NR controller)，可以是5G系统中的gNode B(gNB)，可以是集中式网元(centralized unit)，可以是新无线基站，可以是射频拉远模块，可以是微基站，可以是中继(relay)，可以是分布式网元(distributed unit)，可以是接收点(transmission reception point，TRP)或传输点(transmission point，TP)或者任何其它无线接入设备， 但本申请实施例不限于此。
本申请实施例中涉及的终端设备，是用户侧的一种用于接收或发射信号的实体。终端设备可以是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。终端设备也可以是连接到无线调制解调器的其他处理设备。终端设备可以与无线接入网(radio access network，RAN)进行通信。终端设备也可以称为无线终端、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端(remote terminal)、接入终端(access terminal)、用户终端(user terminal)、用户代理(user agent)、用户设备(user device)、或用户设备(user equipment，UE)等等。终端设备可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，终端设备还可以是个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、等设备。常见的终端设备例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、车辆、路边设备、飞行器、可穿戴设备，例如智能手表、智能手环、计步器等，但本申请实施例不限于此。以下对本申请所提供的通信方法及相关设备进行详细地介绍。
为了能够提高下行数据的传输速率，本申请实施例提供了一种数据处理方法及装置，下面进一步对本申请实施例提供的数据处理方法及装置进行详细介绍。
请参见图4，图4为本申请实施例提供了一种数据处理方法的流程示意图。该方法可以应用于终端设备包括的PDCP实体中，当PDCP实体执行该数据处理方法时，可以包括以下步骤：
410、确定目标数据包的类型为传输控制协议TCP报文到达确认ACK。
PDCP实体可以在检测到类型为TCP ACK的数据包时确定该数据包为目 标数据包。其中，该目标数据包可以来自终端设备的中高层。PDCP实体可以在确定该目标数据包后，就自动为其分配一个序列号(SN编号)，该序列号称为初始序列号。该初始序列号是根据已经占用的序列号来确定的。例如，序列号已经被使用到了400，那么当PDCP实体确定该目标数据包为TCP ACK，就可以自动为其分配序列号为401，该401就是目标数据包的初始序列号。
420、将目标数据包在待发送数据包队列中的序列号由初始序列号修改为目标序列号，该目标序列号小于初始序列号。
在一种可能的实现方式中，该目标序列号可以是该待发送数据包队列中的待发送的第一个数据包的序列号。PDCP实体中，待发送数据包队列中各个数据包的序列号是由小到大排列的，也就是说，PDCP实体可以将该目标数据包放在待发送数据包队列中的最前面。那么相应地，待发送数据包队列中的其他数据包的序列号都会因为该目标数据包的序列号的修改而产生相应的变动。PDCP实体可以针对待发送数据包队列中除该目标数据包以外的各个数据包，更新数据包的序列号，更新后数据包的序列号为更新前的数据包的序列号与1之和。
例如，如图5所示为一种确定目标序列号的方法示意图。该示意图中包括待发送数据包队列。在该待发送数据包队列中，PDCP实体已将序列号为0～99的数据包都发送出去，且序列号为100～400的数据目前正处于待发送状态。当PDCP实体确定了一个目标数据包为TCP ACK，PDCP实体就会自动分配的初始序列号就应该为401，即排到该待发送数据包队列的最后。考虑到应及时发送该目标数据包，PDCP实体此时应目标数据包的序列号由初始序列号修改为目标序列号。该目标序列号可以是待发送数据包队列中待发送的第一个数据包的序列号，即100。此时，PDCP实体可以将该目标数据包的序列号设置为100，相应地，将其他的所有的待发送数据的序列号均向后顺移一个单位。如，原先序列号为100的数据包顺移后为101，原先序列号为210的数据包顺移为211，原先序列号为400的数据包顺移为401，以此类推。这样PDCP实体可以在下一次就将该目标数据包发送出去，不需要排队到序列号为100～400的数据包之后，即不需要排队在初始序列号401处。
在一种可能的实现方式中，PDCP实体可以针对待发送数据包队列中的各 个数据包，更新数据包的序列号，更新后数据包的序列号为更新前的数据包的序列号与1之和。此时该待发送数据包队列中的待发送的第一个数据包的位置则空出，PDCP实体可以将该第一个数据包的位置对应的序列号确定为该目标数据包的目标序列号。换言之，PDCP实体也可以先将待发送数据包队列中的除该目标数据包的序列号都进行加1运算，则可以留出待发送数据包队列中待发送的第一个数据包的位置，该第一个数据包的位置则可以为目标序列号。
在一种可能的实现方式中，若待发送数据包队列中不存在待发送的数据包，那么PDCP实体确认的目标数据包的初始序列号则与目标序列号相同。
在一种可能的实现方式中，类型为TCP ACK的数据包包括确认号；该确认号用于指示终端设备期待接收到的下一个数据包的数据序号，确认号携带于上行数据中，数据序号携带于下行数据中。PDCP实体可以确定待发送数据包队列中与该目标数据包匹配的第一数据包，其中该第一数据包与目标数据包属于同一数据流，且第一数据包中的确认号小于目标数据包的确认号。那么PDCP实体就可以将该第一数据包从待发送数据包队列中删除。删除该第一数据包，PDCP实体可以对该待发送数据包队列中的其他的数据包的序列号进行相应地变动，例如将该第一数据包之后的数据包的序列号进行减1的运算。这是因为，该目标数据包较第一数据包更新，目标数据包的确认号可以指示接收到的下行数据中序列号为该目标数据包中的确认号之前的所有数据，第一数据包可以指示接收到的下行数据中序列号为该第一数据包中确认号之前的所有数据。这样目标数据包的确认号所指示的范围就可以覆盖第一数据包的确认号所指示的范围。
举例来说，若第一数据包的序列号为200，第一数据包的确认号为101，目标数据包的确认号为301，待发送数据包队列中各个数据包的序列号分布为100～400。那么PDCP实体可以确定序列号100为该目标数据包的目标序列号，进一步地，通过对比发现第一数据包的确认号(101)小于目标数据包的确认号(301)。说明，目标数据包的确认号可以指示接收到了下行数据中序列号为300之前的数据，第一数据包的确认号可以指示接收到了下行数据中序列号为100之前的数据。那么当PDCP实体确认了目标数据包更优先发送时， 就可以将第一数据包删除，因为此时的第一数据包的作用已失效。
在一种可能的实现方式中，类型为TCP ACK的数据包包括确认号。PDCP实体可以从待发送数据包队列中确定该目标数据包匹配的第二数据包，该第二数据包与目标数据包属于同一数据流，且第二数据包中的确认号小于目标数据包的确认号。那么PDCP实体就可以将该第二数据包的序列号确定为该目标数据的目标序列号。这是因为，该目标数据包较第二数据包更新，目标数据包的确认号可以指示接收到的下行数据中序列号为该目标数据包中的确认号之前的所有数据，第二数据包可以指示接收到的下行数据中序列号为该第二数据包中的确认号之前的所有数据。这样目标数据包的确认号所指示的范围就覆盖了第二数据包的确认号所指示的范围。PDCP实体在确定目标序列号为第二数据包的序列号后，可以将该第二数据包从该待发送数据包队列中删除。通过这种方式，一方面，可以确保优先发送新TCP ACK数据包(即目标数据包)，从而有利于缩短回环时间(Round Trip Time，RTT)；另一方面，无需更改未被替换的待发送数据包(包括旧TCP ACK数据包(即第二数据包)和/或非TCP ACK数据包)的序列号，有利于降低开销。
需要说明的是，当与目标数据包匹配的第二数据包的个数为一个以上时，PDCP实体可以将其中序列号最小的第二数据包的序列号确定为目标序列号。
例如，如图6所示为另一种确定目标序列号的方法示意图，其中，该图中包括目标数据包1(TCP ACK4)和目标数据包2(TCP ACK5)。TCP ACK1是该TCP ACK5所匹配的数据包(即TCP ACK5对应的第二数据包1)，TCP ACK5中的确认号大于TCP ACK1的确认号，且TCP ACK1和TCP ACK5属于同一数据流，即第一数据流。在该例子中，TCP ACK1的在待发送数据包队列中的序列号为101，TCP ACK2的序列号为100，TCP ACK3的序列号为102。PDCP实体可以在确定TCP ACK5为TCP ACK后，自动确定该TCP ACK5的初始序列号为401。当PDCP实体确定与TCP ACK5匹配的TCP ACK1后，则可以将TCP ACK1的序列号确定为TCP ACK5的目标序列号。则PDCP实体可以将TCP ACK5的序列号由初始序列号(401)修改为目标序列号(101)，并且PDCP实体可以将TCP ACK1从待发送数据包队列中删除。
又例如，图6中，TCP ACK2和TCP ACK3是TCP ACK4所匹配的数据 包(即TCP ACK2和TCP ACK3都是TCP ACK4对应的第二数据包2，第二数据包2的个数为2个)，TCP ACK4中的确认号大于TCP ACK2和TCP ACK3的确认号，且TCP ACK2、TCP3和TCP ACK4属于同一数据流，即第二数据流。PDCP实体可以在确定TCP ACK4为TCP ACK后，自动确定该TCP ACK4的初始序列号为402。当PDCP实体确定与TCP ACK4匹配的TCP ACK2和TCP ACK3后，则可以确定TCP ACK2和TCP ACK3中序列号较小的TCP ACK的序列号为目标序列号。由于TCP ACK2的序列号(100)小于TCP ACK3的序列号(102)，那么PDCP实体就会确定TCP ACK4的目标序列号为TCP ACK2的序列号，即100。并且，PDCP实体还可以将TCP ACK2和TCP ACK3均从该待发送数据包队列中删除。
需要说明的是，属于不同数据流的数据包的确认号是独立的，不同数据流的ACK不会互相干扰。如上述举例中，TCP ACK5与TCP ACK2不属于同一数据流，那么PDCP实体不会将TCP ACK2的序列号作为TCP ACK5的目标序列号，也不会将TCP ACK1的序列号作为TCP ACK4的目标序列号。
在一种可能的实现方式中，PDCP实体可以先从待发送数据包队列中确定该目标数据包匹配的第二数据包，将该第二数据包删除，再确定该第二数据包的序列号为目标数据包的目标序列号。换言之，PDCP实体也可以先将待发送数据包队列中的第二数据包删除，再确定该第二数据包对应的序列号为目标数据包的目标序列号。若第二数据包的个数为一个以上，则PDCP实体可以先删除待发送数据包队列中的所有第二数据包，再确定待发送数据包队列中空出的位置中序列号最小的位置对应的序列号为目标序列号。
430、按照序列号从小到大的顺序发送待发送数据包队列中的各个数据包。
待发送数据包队列中的各个数据包是以从小到大的序列号进行排列的，PDCP实体可以根据该从小到大的顺序发送数据包队列中的各个数据包，这样，就可以实现让目标数据包进行优先发送。
通过本申请实施例，PDCP实体可以在确定目标数据包的类型为TCP ACK后，将目标数据包在待发送数据包队列中的序列号由初始序列号修改为目标序列号，其中，该目标序列号小于初始序列号。当PDCP实体按照序列号从小到大的顺序发送待发送数据包队列中的各个数据包时，目标序列号的目标 数据包就可以相较于初始序列号的目标数据包得到优先发送。目标数据包得到优先发送后，就可以降低TCP ACK数据包的发送延迟，使得接入网设备可以及时确定终端设备已经接收到了已发送的下行数据，这样就可以避免对已送达的下行数据进行重传，从而有利于提高下行数据的传输速率。
