具体实施方式
下面将结合附图对本发明实施例中的技术方案进行描述。
请参阅图1，图1是本发明实施例提供的一种示例通信系统的可能的网络架构。该示例通信系统可以是4G LTE通信系统或5G NR通信系统，具体包括网络侧设备和终端，终端接入网络侧设备提供的移动通信网络时，终端与网络侧设备之间可以通过无线链路通信连接，该通信连接方式可以是单连接方式或者双连接方式或者多连接方式，但通信连接方式为单连接方式时，网络侧设备可以是LTE基站或者NR基站(又称为gNB基站)，当通信方式为双连接方式时(具体可以通过载波聚合CA技术实现，或者多个网络侧设备实现)，且终端连接多 个网络侧设备时，该多个网络侧设备可以是主基站MCG和辅基站SCG，基站之间通过回程链路backhaul进行数据回传，主基站可以是LTE基站，辅基站可以是LTE基站，或者，主基站可以是NR基站，辅基站可以是LTE基站，或者，主基站可以是NR基站，辅基站可以是NR基站。
本发明实施例中，名词“网络”和“系统”经常交替使用，本领域技术人员可以理解其含义。本发明实施例所涉及到的终端可以包括各种具有无限通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile Station，MS)，终端设备(terminal device)等等。为方便描述，上面提到的设备统称为终端。
请参阅图2，图2是一种示例通信系统的RLC层级联和切割示意图，如图2所示，在LTE系统中具有多个RLC服务数据单元(英文：service Data Unit，SDU)，为了描述方便，如图2所示，将多个SDU命名为：SDUa、SDUb和SDUc。在基站为终端提供的传输资源大于一个SDU时，终端可以将多个SDU级联成为一个RLC协议数据单元(英文：protocol data unit，PDU)，如图2所示，终端将SDUa、SDUb和SDUc级联成一个PDU，该PDU的包含：SDUa、SDUb以及SDUc segment1，由于基站为终端分配的传输资源的大小有限，无法包含SDUa、SDUb和SDUc，所以在级联SDUa和SDUb时，需要将SDUc切割成SDUc segment1和SDUc segment2，将SDUc segment1级联至PDU。
对于级联和切割RLC SDU的操作，只有在RLC协议层获得媒体接入控制(英文：medium access control，MAC)层通知的传输机会(也就是授权资源)之后，才能开始组装RLC PDU的操作(其中，将多个RLC SDU组装成RLC PDU，此组装的过程可能需要级联和切割操作)。
对于这两个功能(即级联和切割)，RLC实体(例如智能终端，包括但不限于：手机、平板电脑、笔记本电脑等等)是默认在任何条件下都开启的，即非可配置的，这在有些情况下，比如业务对时延要求敏感，这种实时的级联和切割操作会引起时延，导致不能满足业务对时延要求敏感下时延业务的QoS要求。
在正在标准化的NR讨论中，已经同意将级联功能从RLC层移除，主要考虑就是为了能够进行RLC层的RLC PDU包的预处理，即RLC层不用在获得的MAC层的资源授权就可以开始组装RLC PDU。在这种情况下，RLC层一旦获得MAC层的资源授权，就可以将已经组装好的RLC PDU送入MAC层进一步组装成MAC层的PDU。值得注意的是，NR RLC依然保留了切割的操作，目的还是为了更充分的使用MAC层的授权资源(即如果有剩余资源，也可以将RLC SDU进行切割来填满授权资源)。保留RLC的切割操作同样也可以引入时延，比如已经组装好的RLC PDU由于不能完全的填满MAC层的授权资源，需要重新进行切割，所以在RLC PDU组装时会产生时延，此无法满足一些时延敏感性业务的时延要求。
参阅图3，图3为本发明具体实施方式提供的一种无线链路层的数据包切割配置方法，该方法由终端执行，该终端具体可以为：智能手机、平板电脑、笔记本电脑等等设备，该方法如图3所示，包括如下步骤：
步骤S300、终端与基站建立数据无线承载。
步骤S301、终端接收基站发送的配置RLC的切割功能开关以及配置准则。
终端确定终端与基站的逻辑信道的信道质量是否符合配置准则，该终端配置RLC的切割功能开关。
上述步骤S301中的配置准则可以有多种实现方式，例如在本发明另一较佳实现方式中，该配置准则可以由基站在于终端建立数据无线承载(DRBs)时，通过一个控制信令给终端下发的配置准则。
上述终端配置RLC的切割功能开关的实现方法具体可以为：基站通过控制信令(RRC信令)来配置RLC的切割功能开关，例如，可以在在RRC信令中增加一个指示域，比如segmentation-config，其值为Boolean格式，1表示ON，0表示OFF，当然在实际应用中，也可以是1表示OFF，0表示ON。下面以1表示ON，0表示OFF为例，针对RLC AM和UM，可以标示为如下形式：
Figure PCTCN2017083106-appb-000001
Figure PCTCN2017083106-appb-000002
步骤S302、终端配置RLC的切割功能开关，确定是否符合配置准则，如确定符合该配置准则，关闭该RLC的切割功能开关。
本发明提供的技术方案通过对终端配置RLC的切割功能开关，确定终端是否符合配置准则，如符合配置准则关闭该逻辑信道的RLC的切割功能，此技术方案由于将RLC的切割功能关闭，所以终端无需对该RLC的SDU进行切割处理，所以不会产生时延，所以其具有满足业务对时延要求敏感下时延业务的QoS要求的优点。
参阅图4，图4为本发明具体实施方式提供的一种无线链路层的数据包切割配置方法，该方法在如图1所示的技术场景下实现，该终端与基站均支持5G，该方法由终端执行，该终端具体可以为：智能手机、平板电脑、笔记本电脑等等设备，该方法如图4所示，包括如下步骤：
步骤S401、基站与终端建立数据无线承载。
步骤S402、基站向终端下发无线资源控制(英文：Radio Resource Control，RRC)信令以及配置条件，该RRC信令包含指示域，该指示域用于指示终端配置RLC的切割功能开关。
步骤S403、终端接收基站分配的逻辑信道的上行授权资源，终端检测该上行授权资源大于门限阈值的次数，如该次数大于次数阈值，确定满足配置条件，终端将功能开关关闭。
可选的，上述方法在步骤S403之后还可以包括：
如该次数大于次数阈值，启动定时器，如定时器达到设定值，开启RLC的切割功能(即开启该功能开关)，如未定时器达到设定值，关闭RLC的切割功能。上述定时器的具体指可以有多种设置方式，例如，在本发明一个可选技术方案中，定时器的设定值可以由用户预配置。又如，在本发明另一可选技术方案中，定时器的设定值可以根据逻辑信道的信道条件自行调整。
如图4所示的技术方案通过对预设条件配置成上行授权资源大于门限阈值的次数，且次数大于次数阈值来实现对RLC的切割功能关闭，其依据上行授权资源较大时(即逻辑信道条件比较好)的情况下，降RLC的切割功能关闭以减少时延。此技术方案的原理为，对于上行授权资源比较大的情况下，此时逻辑信道的条件一般比较好，此时关闭RLC切割功能虽然无法填满上行授权资源，但是由于逻辑信道的条件比较好，所以舍弃一些分配的上行授权资源以减少时延是有必要的，对业务的影响也非常小，反之，对于上行授权资源比较小的情况下，此时上行授权资源非常有限，需要尽可能的利用所有的上行授权资源，此时，需要通过开启RLC切割功能使得RLC PDU尽可能的填满，此时，充分利用上行授权资源但是会增加时延。
参阅图5，图5为本发明具体实施方式提供的一种无线链路层的数据包切割配置方法，该方法在如图1所示的技术场景下实现，该终端与基站均支持5G，该方法由终端执行，该终端具体可以为：智能手机、平板电脑、笔记本电脑等等设备，该方法如图5所示，该终端预配置RLC的切割功能开关和预配置了配置条件，该方法包括如下步骤：
步骤S501、基站与终端建立数据无线承载。
步骤S502、基站向终端下发RRC信令以及配置条件，该RRC信令包含指示域，该指示域用于指示终端配置RLC的切割功能开关。
步骤S503、终端接收基站分配的逻辑信道的上行授权资源，终端检测该上行授权资源大于该逻辑信道的RLC SDU大小的平均值，确定满足配置条件，终端将RLC的切割功能关闭。
如图5所示技术方案检测上行授权资源是否大于RLC SDU大小的平均值， 当大于RLC SDU大小的平均值时，关闭RLC的切割功能，此技术方案的思路可以为，对于单个RLC SDU来说，由于上行授权资源的大小大于RLC SDU大小的平均值，即至少大部分的RLC SDU是无需进行RLC切割即能够通过上行授权资源发送至基站，所以该技术方案能够在不影响RLC SDU发送的前提下，尽量的减少时延，从而具有减少时延的优点。
参阅图6，图6为本发明具体实施方式提供的一种无线链路层的数据包切割配置方法，该方法在如图1所示的技术场景下实现，该终端与基站均支持5G，该方法由终端执行，该终端具体可以为：智能手机、平板电脑、笔记本电脑等等设备，该方法如图6所示，该终端预配置RLC的切割功能开关和预配置了配置条件，该方法包括如下步骤：
步骤S601、基站与终端建立数据无线承载.
步骤S602、基站向终端下发RRC信令以及配置条件，该RRC信令包含指示域，该指示域用于指示终端配置RLC的切割功能开关。
步骤S603、终端接收基站发送的动态信令，该动态信令包含RLC切割功能是否关闭的指示，如该指示为关闭该功能开关，终端将该功能开关关闭。
上述动态信令具体可以为：媒体介入层控制元件(Media Access Control Control Element，MAC CE)或下行控制信息(英文：Downlink Control Information，DCI)信令。上述指示具体可以为新增的一个指示域。
如图6所示技术方案通过基站向终端下发的控制信令来实现RLC切割功能的关闭，在RLC切割功能关闭后，具有减少时延的优点。
参阅图7，图7提供一种终端70，其特征在于，所述终端包括：处理单元701和通信单元702，

通信单元702，还用于接收所述基站发送的配置无线链路层控制协议RLC的切割功能开关以及配置准则；
处理单元701，用于配置所述RLC的切割功能开关，确定是否符合配置准则，如确定符合所述配置准则，关闭所述RLC的切割功能开关。
本发明提供的技术方案通过对终端配置RLC的切割功能开关，确定终端是否符合配置准则，如符合配置准则关闭该逻辑信道的RLC的切割功能，此技术方案由于将RLC的切割功能关闭，所以终端无需对该RLC的SDU进行切割处理，所以不会产生时延，所以其具有满足业务对时延要求敏感下时延业务的QoS要求的优点。
