Description

数据传输方法及装置 技术领域
本公开涉及通信领域，具体而言，涉及一种数据传输方法及装置。
背景技术
第五代移动通信技术(5th-generation，简称为5G)网络架构具有革新性和组网的灵活性，在5G网络中无线接入网侧的基站被分离为两个功能实体：集中式处理单元(Centralized Unit，简称为CU)和分布式处理单元(Distributed Unit，简称为DU)。一个基站包含一个CU，以及一个或者多个DU。在CU/DU分离的网络架构中，将时延不敏感的网络功能放在第一网元(例如，CU中)，将时延敏感的网络功能放在第二网元(例如，DU中)，第一网元与第二网元之间通过理想和/或非理想的前传网络进行传输，如图1所示。
在现有的CU/DU分离架构中，对于CU/DU高层分离方案(如图2所示)，将分组数据汇聚协议层(Packet Data Convergence Protocol，简称为PDCP)及其PDCP以上的层放在CU，无线链路控制层(Radio Link Control，简称为RLC)及其RLC以下的层放在DU。在CU/DU架构下，一个终端可以和一个DU中的多个载波建立载波聚合方式的多连接，也可以和一个CU下的多个DU建立多个连接。为了提高数据传输的可靠性，CU在向终端发送业务承载数据时，可以向不同的连接上发送相同数据的拷贝。相应地，终端向CU发送业务承载数据时，可以向不同的连接上发送相同数据的拷贝。这种数据传输方式称之为duplication(重复)传输。这样终端即使在一条链路上没有收到网络侧发送的数据，但是终端也可以在另一条链路上收到相同的数据(网络侧接收终端发送的数据时与此类似)，这样可以大大提高终端业务数据接收的可靠性，降低丢包率。
现以下行数据的传输为例对duplication传输进行说明。
如图3所示，是终端基于载波聚合方式与一个DU中的多个载波建立起多连接方式。终端的业务承载在CU和DU之间建立的两个数据传输通道，在图3中为两个F1数据传输通道，CU向两个数据传输通道发送相同的数据(在图3中为PDCP PDU1(Protocol Data Unit，协议数据单元))。DU接收到数据后，分别将不同传输通道上的数据通过不同的逻辑信道发送给终端。其中，图3中的RRC、PDCP等与图2中的NR(New Radio，新型无线)RRC、NR PDCP等分别对应。
如图4所示，是终端基于多DU连接方式和一个CU中的多个DU建立起多连接。CU和不同的DU通过各自的F1数据通道相连接，CU向两个DU发送相同的数据(在图4中为PDCP PDU1)，DU接收到数据后，将数据发送给终端。
然而，相关技术中采用duplication传输的方式进行数据传输，存在传输资源耗费较大的问题。
发明内容

需要说明的是，本公开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。
实施例1
本申请实施例1所提供的方法实施例可以在集中式处理单元、分布式处理单元或者类似的运算装置中执行。以运行在移动终端上为例，图5是本公开实施例的数据传输方法的集中式处理单元的硬件结构框图。如图5所示，集中式处理单元50可以包括一个或多个(图中仅示出一个)处理器52(处理器52可以包括但不限于微处理器MCU或可编程逻辑器件FPGA等的处理装置)、用于存储数据的存储器54、以及用于通信功能的传输装置56。本领域普通技术人员可以理解，图5所示的结构仅为示意，其并不对上述电子装置的结构造成限定。例如，集中式处理单元50还可包括比图5中所示更多或者更少的组件，或者具有与图5所示不同的配置。
存储器54可用于存储应用软件的软件程序以及模块，如本公开实施例中的数据传输方法对应的程序指令/模块，处理器52通过运行存储在存储器54内的软件程序以及模块，从而执行各种功能应用以及数据处理，即实现上述的方法。存储器54可包括高速随机存储器，还可包括非易失性存储器，如一个或者多个磁性存储装置、闪存、或者其他非易失性固态存储器。在一些实例中，存储器54可进一步包括相对于处理器52远程设置的存储器，这些远程存储器可以通过网络连接至集中式处理单元50。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
传输装置56用于经由一个网络接收或者发送数据。上述的网络具体实例可包括集中式处理单元50的通信供应商提供的无线网络。在一个实例中，传输装置56包括一个网络适配器(Network Interface Controller，NIC)，其可通过基站与其他网络设备相连从而可与互联网进行通讯。在一个实例中，传输装置56可以为射频(Radio Frequency，简称为RF)模块， 其用于通过无线方式与互联网进行通讯。
相关技术中采用duplication传输的方式进行数据传输。然而，虽然网络侧通过duplication技术，在不同连接的链路上给终端发送相同的数据来提供终端接收数据的可靠性。但是duplication技术需要耗费多余的传输资源，比如在其中一个链路质量非常好的情况下可以关闭duplication数据传输功能，只在一条链路上发送以节省传输资源。又比如，在两条链路质量都很好的情况下，关闭duplication数据传输功能，并在两条链路上发送不同的数据，以提高终端业务数据速率。再比如，在其中一条链路质量非常差的情况下，关闭duplication数据传输功能，因为此时由于一条链路质量很差，在这条链路上发送相同数据的拷贝已经没有意义。因而，数据传输duplication数据传输功能的开启或者关闭可以通过对下行链路传输质量的判断来进行。
在CU/DU分离的架构下，相同数据的拷贝是由CU向不同链路发送的，但是CU并不能及时的判断DU下行链路质量，所以CU很难决定是否开启还是关闭duplication数据传输功能。因此，在CU/DU分离的情况下，需要考虑如何判决是否在和终端相连的多条链路上开始和关闭duplication传输功能。
在本实施例中提供了一种运行于上述集中式处理单元或分布式处理单元的数据传输方法，图6是根据本公开实施例的数据传输方法的流程图，如图6所示，该流程包括如下步骤：
步骤S602，获取多个信道的信道传输质量的测量结果，其中，在上述多个信道上配置有重复数据传输功能，该重复数据传输功能用于指示在上述多个信道上建立与终端之间的多连接，该多连接用于在上述多个信道上同时传输相同数据；
步骤S604，根据获取的测量结果，判断是否开启该重复数据传输功能；
步骤S606，根据判断结果，在上述多个信道中进行与所述终端之间的数据传输。
通过上述步骤，在多个信道上配置有重复数据传输功能，并根据多个信道的信道传输质量的测量结果，判断是否开启重复数据传输功能，从而在有需要时开始重复数据传输功能，在保证链路传输质量同时，避免了传输资源的浪费，解决了相关技术中采用duplication传输的方式进行数据传输，存在传输资源耗费较大的问题，提高了链路传输质量，减少了传输资源消耗。
可选地，上述步骤的执行主体可以为集中式处理单元(CU)或分布式处理单元(DU)等，但不限于此。
可选地，步骤S606可以包括：在判断结果指示重复数据传输功能为开启的情况下，在多个信道对应的多连接上与终端进行相同数据的传输。即，在多连接对应的多个信道上向终端发送相同的数据，或者，接收终端发送的相同的数据。
可选地，判断结果指示为重复数据传输功能为开启可以包括两种情况：在进行判断之前，重复数据传输功能已开启，则保持重复数据传输功能的开启不变；在进行判断之前，重复数据传输功能未开启，则开启重复数据传输功能。
可选地，步骤S606还可以包括：在判断结果指示为重复数据传输功能为不开启的情况下，在多个信道中确定一个信道与终端进行数据传输。
可选地，判断结果指示为重复数据传输功能为不开启可以包括两种情况：在进行判断之前，重复数据传输功能已开启，则关闭重复数据传输功能；在进行判断之前，重复数据传输功能未开启，则保持重复数据传输功能的关闭状态。
可选地，在判断结果指示为重复数据传输功能不开启的情况下，在多个信道中确定一个信道与终端进行数据传输可以包括多种方式。
作为一种可选的方式，获取信道传输质量高于指定阈值的第一信道，根据第一信道确定与终端进行数据传输的信道。例如，可以预先指定阈值，对于信道传输质量高于该阈值的信道只有一个的情况(即，信道传输质量最高的信道)，可以将该信道确定为与终端进行数据传输的信道。对于信道传输质量高于该阈值的多个信道，可以将其中的一个确定为与终端进行数据传输的信道。又例如，也可以选取上述多个信道中信道传输质量最高(最好)的信道，将该信道确定为与终端进行数据传输的信道。
作为另一种可选的方式，可以预先指定多个信道中的一个信道作为默认信道(第二信道)，在判断结果指示为重复数据传输功能不开启的情况下，将该默认信道确定为与终端进行数据传输的信道。
可选地，步骤S604可以采用多种方式确定是否开启重复数据传输功能。例如，可以在测量结果指示多个信道的信道传输质量均满足预设条件的情况下，确定开启所述重复数据传输功能；在测量结果指示多个信道中的至少一个信道的信道传输质量不满足预设条件的情况下，确定不开启重复数据传输功能。其中，预设条件包括：信道传输质量高于第一预设阈值并且低于第二预设阈值，其中，第二预设阈值大于第一预设阈值。
下面对此进行说明。对于信道传输质量高于第二预设阈值的信道，说明该条链路质量很好，因此，可以关闭重复数据传输功能，只在一条链路上发送数据。对于信道传输质量低于第一预设阈值的信道，说明该条链路质量非常差，在这条链路上发送相同数据的拷贝已经没有意义，可以考虑关闭重复数据传输功能。作为一种可选的方式，在某一信道的信道传输质量低于第一预设阈值时，也可以考虑忽略该信道，而在多个信道中除了该信道以外的其他信道中进行重复数据传输(同时传输相同数据)。
可选地，步骤S602可以采用多种方式获取该测量结果。作为一种可选的方式，对于CU，可以接收一个或多个DU上报的测量结果，其中，测量结果为一个或多个DU对多个信道的信道传输质量进行测量后得到。例如，对于duplication数据传输功能同一DU和终端的多连接，则CU可以接收该DU发送的对多个信道进行信道质量测量的测量结果。又例如，对于duplication数据传输功能是同一CU下的不同DU与终端的多连接，CU可以接收不同的DU发送的对各自信道进行信道质量测量的测量结果。作为另一种可选的方式，对于DU，DU可以对多个信道的信道传输质量进行测量，并据此获取该测量结果。
可选地，在步骤S604之后，可以包括：在CU获取到上述判断结果之后，CU可以向DU发送用于指示是否开启重复数据传输功能的第一指示消息。DU可以根据接收到的第一指示消息后，可以清除与多连接有关的缓存，也可以根据指示消息通知终端是否开启重复数据传输功能。还可以包括：在DU获取到判断结果之后，DU可以向CU发送用于指示是否 开启重复数据传输功能的第二指示消息，以便CU根据该指示消息执行相应的操作，例如，向上述多个信道上发送相同的数据，又例如，停止向上述多个信道上发送相同的数据。
可选地，上述测量结果可以是“链路传输质量异常指示”或“链路传输质量恢复指示”之一，也可以是以下的一项或者多项，但不限于：信道质量指示(Channel Quality Indication，简称为CQI)测量结果，探测参考信号(Sounding Reference Signal，简称为SRS)测量结果，下行缓存数据传输时延测量结果，无线链路控制(Radio Link Control，简称为RLC)重传次数测量结果，混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)重传次数测量结果。
基于上述实施例及优选实施方式，为说明方案的整个流程交互，在本优选实施例中，提供了一种数据传输方法。下面对该方法进行具体说明。需要说明的是，在本优选实施例中，数据传输以下行数据传输为例进行说明。相应地，信道的信道传输质量为下行信道的信道传输质量。对于上行数据传输，其与下行数据传输类似，再次不做赘述。
本优选实施例适用于基站在CU/DU分离情况下，终端和网络侧有多条连接的情况下，网络侧判决是否开启和关闭duplication数据传输功能(即，上述重复数据传输功能)。
作为一种可选的方式，本优选实施例中的数据传输方法可以包括以下步骤：
步骤1，DU对下行信道传输质量的测量(这种测量可以包括以下一项或者多项，但不限于以下：终端上报的CQI测量报告，SRS测量，下行缓存数据传输时延，RLC重传次数，HARQ重传次数测量等)。
步骤2，如果duplication数据传输功能是在同一个DU下和终端的多个连接中配置的，那么DU可以根据步骤1中测量到的和终端相连的各个不同链路中的传输质量，来判断是否在本DU和终端相连的多条链路上开启duplication数据传输功能。并且DU发送“duplication指示”消息(作用同前述第二指示消息)给CU，消息中包含duplication的判决结果，用于通知CU是否开启，或者关闭了duplication数据传输功能。CU接收到DU上报的“duplication指示”消息，如果该消息中指示开启duplication数据传输功能，则CU可以向和终端相连的多条链路发送相同的数据；如果该消息中指示关闭duplication数据传输功能，则CU停止向终端相连的多条链路发送相同的数据，结束。
如果duplication数据传输功能是在同一个CU下和不同的DU和终端的多个连接中配置的，那么DU向CU上报下行信道传输质量测量结果。那么DU向CU上报下行信道传输质量结果。(测量结果的上报可以是“链路传输质量异常指示”或“链路传输质量恢复指示”之一，又或者是以下的一项或者多项，但不限于：如CQI测量结果，SRS测量结果，下行缓存数据传输时延测量结果，RLC重传次数测量结果，HARQ重传次数测量结果)。
步骤3，CU接收到DU上报的终端下行信道传输质量结果，CU根据各链路质量判断是否开启或者关闭duplication数据传输功能。如果判决开启duplication数据传输功能，则CU可以向和终端相连的多条链路发送相同的数据；如果判决关闭duplication数据传输功能，则CU停止向终端相连的多条链路发送相同的数据。可选的，CU可以通过发送“duplication指示”消息给DU，消息中包含duplication的判决结果，通知DU网络侧是否已经开启或者关 闭了duplication数据传输功能。
下面结合具体的实例对本优选实施例中的数据传输方法进行说明。
实例1
图7是根据本公开优选实施例中的DU下行信道质量的测量装置的示意图，该装置用于网络侧下行duplication判决。
如图7所示，该测量装置针对下行信道传输质量的测量。这种测量可以包括以下一项或者多项，但不限于：终端上报的CQI测量报告，SRS测量，下行缓存数据传输时延，RLC重传次数，HARQ重传次数测量等)。测量结果用于本DU直接判决是否开启或者关闭本DU上的终端业务承载多条链路的duplication数据传输功能；或者测量结果用于上报给CU，用于CU来判决是否开启或者关闭终端业务承载多条链路的duplication数据传输功能。
实例2
图8是根据本公开优选实施例的一个DU下多连接的duplication传输的流程图一。在本实例中，终端和同一个DU建立了多条连接，接收下行数据，并由DU判决是否开启或者关闭duplication数据传输功能。如图8所示，该流程包括如下步骤：
步骤1，DU进行下行信道质量测量，并根据测量到的和终端相连的各个不同链路中的传输质量，来判断是否在本DU和终端相连的多条链路上开启duplication功能(即，duplication数据传输功能)。
步骤2，DU发送“duplication指示”消息给CU。
“duplication指示”消息中包含duplication功能的判决结果，用于通知CU是否开启或者关闭了duplication功能。
步骤3，CU接收到DU上报的“duplication指示”消息，如果duplication指示消息中指示开启duplication功能，则CU向和终端相连的多条链路发送相同的数据；如果duplication指示消息中指示关闭duplication功能，则CU停止向终端相连的多条链路发送相同的数据。
CU接收到DU上报的“duplication指示”消息，如果该消息中指示开启duplication功能，则CU可以向和终端相连的多条链路发送相同的数据；如果该消息中指示关闭duplication功能，则CU停止向终端相连的多条链路发送相同的数据。
实例3
图9是根据本公开优选实施例的一个DU下多连接的duplication传输的流程图二。在本实例中，终端和同一个DU建立了多条连接，接收下行数据，并由CU判决是否开启或者关闭duplication数据传输功能。如图9所示，该流程包括如下步骤：
步骤1，DU对下行信道传输质量进行测量；
步骤2，DU向CU上报和终端相连的本DU的多条下行链路质量的测量结果；
步骤3，CU根据各链路质量判断是否开启或者关闭duplication功能，如果判决开启duplication功能，则CU可以向和终端相连的多条链路发送相同的数据；如果判决关闭duplication功能，则CU停止向终端相连的多条链路发送相同的数据。
在CU接收到DU上报的终端下行信道传输质量结果后，执行上述步骤。
步骤4，CU通过发送“duplication指示”消息给DU，该消息中包含duplication功能的判决结果，用于通知DU网络侧是否已经开启或者关闭duplication功能。
本步骤为可选步骤。
实例4
图10是根据本公开优选实施例的一个CU下的多个DU的多连接的duplication传输的流程图。在本实例中，终端和同一个CU下的多个DU建立了多条连接，接收下行数据，并由CU判决是否开启或者关闭duplication数据传输功能。如图10所示，该流程包括如下步骤：
步骤1，终端和同一个CU下的多个DU建立了多条连接，不同DU对终端下行信道传输质量的测量；
步骤2，DU向CU上报下行信道传输质量测量结果；
步骤3，CU接收到不同DU上报的终端下行信道传输质量结果，CU根据各链路质量判断是否开启或者关闭duplication功能，如果判决开启duplication功能，则CU向和终端相连的多条链路发送相同的数据；如果判决关闭duplication功能，则CU停止向终端相连的多条链路发送相同的数据。
步骤4，CU通过发送“duplication指示”消息给多个DU，该消息中包含duplication功能的判决结果，通知DU网络侧是否已经开启或者关闭duplication功能。
本步骤为可选步骤。
通过本公开优选实施例的上述技术方案，由CU或者DU根据用于多连接的多个信道的信道传输质量的测量结果，判定是否需要开启或关闭duplication数据传输功能，从而节省了传输资源。进一步地，由CU执行判决时，CU通过与DU的交互，可以及时获知DU的下行链路质量，从而判决是否开启或者关闭duplication数据传输功能。从而解决相关技术中采用duplication传输的方式进行数据传输，存在传输资源耗费较大的问题，达到提高链路传输质量，减少传输资源消耗的效果。
