第五代通信技术(5th-Generation,5G)是一种多技术融合的通信,通过技术的更迭和创新来满足广泛的数据、连接业务的需求。在第三代移动通信伙伴项目(Third Generation Partnership Project,3GPP)RAN2中提出可以对待传输的数据进行预处理,即用户设备(User Equipment,UE)可以将分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)层的服务数据单元(service Data Unit,SDU)处理为PDCP协议数据单元(Protocol Data Unit,PDU),如进行加密和/或完整性校验,及添加PDCP头,并送到更低层,如无线链路层控制(Radio Link Control,RLC)层的缓存中。RLC层也可以进一步地将该PDCP PDU处理为RLC PDU,进一步地,RLC层还可以将该RLC PDU传送到更低层,如介质访问控制(Medium Access Control,MAC)层。在MAC层可以进一步形成MAC PDU。通过上述方式,一旦UE接收到上行调度,就可以将已经处理好的MAC PDU通过空口资源发送给网络设备,从而节省了处理时间,提高了整个链路上的数据传输速率。
然而,在双连接架构下,如果UE分别向两个传输支路分配了预处理的数据,有可能某一条传输支路因为信道质量恶化而无法成功传输,数据长期拥塞在该传输支路上,造成恶劣的用户体验。

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清楚、完整地描述。
接下来请参见图1。图1为本发明实施例提供的一种通信系统架构示意图。如图1所示,通信系统10至少可以包括:UE110、主节点(Master Node,MN)、辅节点(Secondary Node,SN)以及核心网。在实际应用中该通信系统10还可以包含其他设备。
其中,UE可以与两个网络节点即MN和SN分别建立连接。其中,MN通过第一接口与核心网进行交互,SN通过第二接口与核心网交互,MN与SN之间通过第三接口进行交互,MN和UE之间通过第四接口进行交互,SN和UE之间通过第五接口进行交互。具体地,第四接口可以为Uu接口,第五接口可以为Uu接口。本发明实施例中,第一节点可以是MN,也可以是SN。当第一节点为MN时,第二节点为SN;或者当第一节点为SN时,第二节点为MN。
该UE110可以为手机、智能手表等智能终端,还可以为服务器、网关、基站、控制器等通信设备,还可以为传感器、电表、水表等物联网设备,还可以为其他能够接入到蜂窝网或者有线网的设备。
上述两个网络节点可以为网络设备,例如但不限于是演进型基站(evolved Node B,eNB)、下一代基站(Next Generation Node B,gNB)、发送和接收点(Transmission and Reception Point,TRP)、cell、中心单元(Central Unit,CU)、分布单元(Distributed Unit,DU)等。需要说明的是,后续实施例中提到的网络设备即为第一节点或者第二节点。
基于图1所描述的通信系统,接下来结合图2-5说明本发明实施例提供的数据传输方法流程示意图。
如图2所示,数据传输方法至少可以包括以下几个步骤:
S201:在第一传输支路上对第一数据执行第一操作时,启动定时器。
具体的,如图1所示的通信系统的架构示意图,UE与第一节点和第二节点建立双连接后,可以进一步建立分割承载split bearer。其中,该split bearer的各层协议栈对应于UE与第一节点之间的传输支路为第一传输支路,该split bearer的各层协议栈对应于UE与第二节点之间的传输支路为第二传输支路。可以将待传输数据分为第一数据及第二数据,第一数据为已传送至该第一传输支路的RLC层和/或MAC层的数据,可以通过第一传输支路将第一数据传输至第一节点;第二数据为已传送至该第二传输支路的RLC层和/或MAC层的数据,可以通过第二传输支路将第二数据传输至第二节点。
具体地,split bearer可以为MCG split bearer或者SCG split bearer,split bearer包含一个PDCP实体,和2个分别针对MN和SN的RLC实体,及2个分别针对第一节点和第二节点的MAC实体。本发明实施例所描述的PDCP实体、RLC实体、MAC实体可以理解为执行PDCP层、RLC层和MAC层功能的功能模块,与PDCP层、RLC层、MAC层可以相互推导或者替换。该split bearer的协议栈如图3所示,其中,第一传输支路的各层协议栈至少包括PDCP层、RLC#1层、MAC#1层,第二传输支路的各层协议栈至少包括PDCP层、RLC#2层、MAC#2层,其中数据的加密、完整性校验、头压缩等在PDCP层完成,随后传送至RLC层和MAC层。
第一操作可以包括但不限于是以下三种可能的实现方式:
第一种,第一操作可以是在第一传输支路上开始向第一节点传输第一数据。
具体地,当第一数据开始传输后,UE启动定时器,并开始计时。
具体地,UE可以判断是否接收到指示第一数据内任意PDCP PDU传输成功和/或传输失败的指示信息,如PDCP状态报告PDCP STATUS report,或者,UE可以判断是否接收到较低层协议栈(如RLC#1或者MAC#1)的指示信息,指示第一数据中的任意数据已经开始传输,若接收到,则确定第一传输支路已经开始向第一节点传输第一数据。
第二种,第一操作可以是在第一传输支路上完成向第一节点传输第一数据。
具体地,当第一数据完成传输后,UE启动定时器,并开始计时。
具体地,UE确定第一数据完成传输,可以为UE接收到对端响应的指示信息,如PDCP状态报告PDCP STATUS Report,并根据其中的指示信息确定第一数据内的PDCP序列号(serial number,SN)所关联的PDCP PDU全部成功接收,或者第一数据完成传输,可以为UE的PDCP层接收到较低层协议栈的响应信息,该响应信息指示所述第一数据完成传输,例如,PDCP层接收到RLC#1层的第一指示信息,该第一指示信息第一数据已经完成传输,具体地,RLC层根据MAC#1层的第二指示信息确定所述第一指示信息,第二指示信息表明该第一数据已经在无线空口上传输,并已接收到指示成功传输的混合自动重传请求(Hybrid Automatic Repeat request,HARQ)信息。需要说明的是,有可能存在部分PDCP PDU未能成功传输的情况,但是UE仍可以认为第一数据全部完成传输,例如,当PDCP PDU映射于RLC非确认模式(Unacknowledged Mode,UM)时,部分数据未能成功传输并不影响用户体验,因而UE仍可以确定第一数据完成传输。
第三种,第一操作可以是在第一传输支路上完成向第一节点传输部分第一数据。
具体地,当第一数据内的部分数据完成传输后,UE启动定时器,并开始计时。该第 一数据内的部分数据可以为特定数据量的数据,或者为特定PDCP SN号所关联的数据。
具体地,UE可以判断是否接收到指示第一数据特定数量的PDCP PDU传输成功的指示信息,如PDCP STATUS report,或者,UE可以判断是否接收到指示第一数据内特定PDCP SN号所关联的PDCP PDU传输成功的指示信息,如PDCP STATUS report,或者,UE可以判断是否接收到较低层协议栈(如RLC#1或者MAC#1)的指示信息,指示第一数据中的特定数量的PDCP PDU已经完成传输,或者,UE可以判断是否接收到较低层协议栈(如RLC#1或者MAC#1)的指示信息,指示第一数据部分中特定PDCP SN号所关联的PDCP PDU已经完成传输。若接收到,则确定第一传输支路上部分数据完成传输。例如,第一数据内的部分数据为第一数据的50%的数据量,当第一数据有50%的数据量完成传输,则确定第一传输支路上部分数据完成传输;或者第一数据的部分数据为第一数据中所关联的PDCP SN号集合中80%的PDCP SN号对应的PDCP PDU,当第一数据中完成传输的PDCP PDU所关联的SN号数量达到了第一数据所有PDCP PDU关联的SN号数量总和的80%,则确定第一传输支路上部分数据完成传输;或者第一数据中完成传输的PDCP PDU所关联的SN号包含了某一特定PDCP SN号,则确定第一传输支路上部分数据完成传输。
S203:当定时器计时结束时,若在第二传输支路上未对第二数据执行第二操作,则对第二数据执行第三操作。
第二操作可以包括但不限于是以下三种可能的实现方式:
第一种,第二操作可以是在第二传输支路上开始向第二节点传输第二数据。
具体地,UE可以判断是否接收到指示第二数据内任意PDCP PDU传输成功和/或传输失败的指示信息,如PDCP STATUS report,或者,UE可以判断是否接收到较低层协议栈(如RLC#2或者MAC#2)的指示信息,指示第二数据中的任意数据部分已经开始传输。若接收到指示信息,则确定第二传输支路上开始传输第二数据。
第二种,第二操作可以是在第二传输支路上完成向第二节点传输第二数据。
具体地,UE可以判断是否接收到对端响应的指示信息,如PDCP状态报告PDCP STATUS Report,并根据其中的指示信息确定第二数据内的PDCP SN号所关联的PDCP PDU全部成功接收,或者,可以为UE的PDCP层接收到较低层协议栈(如RLC#2或者MAC#2)的响应信息,该响应信息指示所述第二数据完成传输,例如,PDCP层接收到RLC#2层的第三指示信息,该第三指示信息指示第二数据已经完成传输,具体地,RLC#2层根据MAC#2层的第四指示信息确定所述第三指示信息,第四指示信息表明该第二数据已经在无线空口上传输,并已接收到指示成功传输的HARQ信息。需要说明的是,有可能存在部分PDCP PDU未能成功传输的情况,但是UE仍可以认为第二数据全部完成传输,例如,当PDCP PDU映射于RLC UM(unacknowledged mode,非确认模式)模式时,部分数据未能成功传输并不影响用户体验,因而UE仍可以确定第二数据完成传输。
第三种,第二操作可以是在第二传输支路上完成向第二节点传输部分第二数据。
具体地,第二数据内的部分数据可以为特定数据量的数据,或者为特定PDCP SN号所关联的数据。具体地,UE可以判断是否接收到指示第二数据特定数量的PDCP PDU传输成功的指示信息,如PDCP STATUS report,或者,UE可以判断是否接收到指示第二数据内特定PDCP SN号所关联的PDCP PDU传输成功的指示信息,如PDCP STATUS report,或者,UE可以判断是否接收到较低层协议栈(如RLC#2或者MAC#2)的指示 信息,指示第二数据中的特定数量的PDCP PDU已经完成传输,或者,UE可以判断是否接收到较低层协议栈(如RLC#2或者MAC#2)的指示信息,指示第二数据中特定PDCP SN号所关联的PDCP PDU已经完成传输。若接收到,则确定第二传输支路上部分数据完成传输。例如,第二数据内的部分数据为第二数据部分的50%的数据量,则确定在第二传输支路上完成传输部分第二数据;或者第二数据的部分数据为第二数据中所关联的PDCP SN号集合中80%的PDCP SN号对应的PDCP PDU,当第二数据中完成传输的PDCP PDU所关联的SN号数量达到了第二数据所有PDCP PDU关联的SN号数量总和的80%,则确定在第二传输支路上完成传输部分第二数据;或者第二数据中完成传输的PDCP PDU所关联的SN号包含了某一特定PDCP SN号,则确定在第二传输支路上完成传输部分第二数据。
具体地,当定时器计时结束时,若在第二传输支路上未对第二数据执行第二操作,则对第二数据执行第三操作。
第三操作可作至少可以包括但不限于是以下四种中的任意一种或多种情形:
第一种,第三操作可以是取消向第二节点传输第二数据。
具体地,UE可以指示第二传输支路的较低层协议栈对第二数据进行取消传输。
第二种,第三操作可以是删除第二数据。
具体地,UE可以指示第二传输支路的较低层协议栈对第二数据进行删除。
可以知道的是,第三操作还可以是取消向第二节点传输并删除第二数据。
第三种,第三操作可以是取消传输第二数据中尚未传输的部分。
具体地,UE可以指示第二传输支路的较低层协议栈对第二数据中尚未传输的部分数据进行取消传输。该第二数据内的部分数据可以为特定数据量的数据,或者为特定PDCP SN号所关联的数据。
第四种,第三操作可以是删除第二数据中尚未传输的部分。
具体地,UE可以指示第二传输支路的较低层协议栈对第二数据中尚未传输的部分数据进行删除。该第二数据内的部分数据可以为特定数据量的数据,或者为特定PDCP SN号所关联的数据。
可以知道的是,第三操作还可以是取消传输并删除第二数据中尚未传输的部分。
具体地,UE对第二数据执行第三操作,可以为UE通过PDCP层向第二传输支路的较低层协议栈进行指示,例如PDCP层向RLC#2进行指示,或者PDCP层向RLC#2指示后再由RLC#2向MAC#2进行指示,或者PDCP层向MAC#2进行指示,其指示的协议栈层可以为预处理数据所在的协议栈层,指示其对第二数据进行第三操作。
实施本发明实施例可以在用户设备分割承载的上行数传输中,当UE分别向两个传输支路分配了预处理的数据,因某一条传输支路因为信道质量恶化而无法成功传输时的,由定时器控制两条传输支路的传输时差,对该条传输支路上的数据执行第三操作,避免数据长期拥塞在该传输支路上,提升用户体验。
可以理解的是,在本发明实施例中,也可以是在第二传输支路上对第二数据执行第一操作时,启动定时器;当定时器计时结束时,若在第一传输支路上未对第一数据执行第二操作,则对第一数据执行第三操作。
接下来请参见图4。图4为本发明实施例提供的另外一种上行数据传输方法流程示意图。如图4所示,上行数据传输方法可以包括以下几个步骤:
S401:建立分割承载的第一传输支路和第二传输支路的各层协议栈。
具体地,如图1所示的通信系统的架构示意图,UE与第一节点和第二节点建立双连接后,可以进一步建立分割承载split bearer。其中,该split bearer的各层协议栈对应于UE与第一节点之间的传输支路为第一传输支路,该split bearer的各层协议栈对应于UE与第二节点之间的传输支路为第二传输支路。可以将待传输数据分为第一数据及第二数据,第一数据为已传送至该第一传输支路的RLC层和/或MAC层的数据,可以通过第一传输支路将第一数据传输至第一节点;第二数据为已传送至该第二传输支路的RLC层和/或MAC层的数据,可以通过第二传输支路将第二数据传输至第二节点。
具体地,split bearer可以为主小区群(Master Cell Group,MCG)split bearer或者辅小区群(Secondary Cell Group,SCG)split bearer,split bearer包含一个PDCP实体,和2个分别针对MN和SN的RLC实体,及2个分别针对MN和SN的MAC实体。本发明实施例所描述的PDCP实体、RLC实体、MAC实体可以理解为执行PDCP层、RLC层和MAC层功能的功能模块,与PDCP层、RLC层、MAC层可以相互推导或者替换。该split bearer的协议栈如图3所示,其中,第一传输支路的各层协议栈至少包括PDCP层、RLC#1层、MAC#1层,第二传输支路的各层协议栈至少包括PDCP层、RLC#2层、MAC#2层,其中数据的加密、完整性校验、头压缩、重排序等在PDCP层完成,随后传送至RLC层和MAC层。
S402:将第一数据和第二数据分别传送至所述第一传输支路和所述第二传输支路的较低层协议栈。
S403:将第一数据和第二数据分别进行预处理。
需要说明的是,S402和S403的实施过程无先后顺序,且有可能同时交替进行。具体地,第一数据和第二数据可以为传输通路或者第一数据流中的数据,或者为PDCP SDU或者PDCP PDU。当为PDCP SDU时,对第一数据和第二数据进行预处理至少可以包含将PDCP SDU添加到PDCP PDU,具体地,至少可以包含为PDCP SDU分配相应的PDCP SN号,添加PDCP头。第一数据和第二数据的PDCP SN号可以不同或者可以相同(例如,应用于PDCP重复场景下)或者可以部分重合,并发明不作限制。将第一数据和第二数据分别传送至第一传输支路和第二传输支路的较低层协议栈,可以为将第一数据传送至第一传输支路的RLC层或者MAC层,将第二数据传送至第二传输支路的RLC层或者MAC层。在这种情况下,对第一数据和第二数据进行预处理还可以包括:将所述第一数据和第二数据进一步添加到RLC PDU或者MAC PDU。在实际应用中,对第一数据和第二数据预处理的程度不作限制。
S404:接收网络设备发送的定时器信息。
具体地,网络设备可以是第一节点或者第二节点。
接下来详细介绍网络设备为用户设备配置定时器的方法。以网络设备为第一节点为例进行说明。如图5所示,定时器配置方法可以包括以下几个步骤:
S501:确定定时器的时长。
具体地,确定定时器的时长可以包括以下几种方法:
第一种:根据上行数据的服务质量参数确定定时器的时长。
第二种:根据上行数据所在传输通路的服务质量参数确定定时器的时长。
针对以上两种确定定时器时长的方法,具体实现过程如下:
首先,UE与核心网建立第一数据流的传输通路。
其中,第一数据流可以但不限于为服务数据流(Service data flow、SDF)、聚合数据流(SDF Aggregate)、数据流(data flow)、业务数据流(service data flow)、服务质量流(QoS flow)、数据包流(packet flow)等的一种或者多种,相应地,第一数据流的传输通路可以但不限于为演进分组系统承载(Evolved Packet System Bearer,EPS Bearer)、演进的无线接入承载(Evolved Radio Access Bearer,E-RAB)、PDU时域(PDU Session)等。其具体过程可以参考3GPP TS 23.401标准、3GPP TS 23.501标准、3GPP TS23.502标准等相关标准,本发明不再赘述。
其次,第一节点接收第一消息,并根据所述第一消息确定第一定时器时长。
在第一种可能的实施方式中,第一消息携带第一数据流的传输通路的特征信息,第一数据流的传输通路的特征信息可以包含但不限于传输通路的标识信息和传输通路的服务质量(Quality of Service,QoS)参数信息。进一步地,第一消息还可以携带第一数据流的特征信息,如第一数据流的标识信息和第一数据流的QoS参数信息。第一数据流的标识信息可以但不限于为服务标识(service identifier,service ID)、SDF ID、SDF Aggregate ID、data flow ID、service data flow ID、QoS flow ID、packet flow ID等,相应地,第一数据流的传输通路的标识信息可以但不限于为EPS bearer ID、E-RAB ID、PDU Session ID等。第一数据流的QoS参数信息可以但不限于包含第一数据流的标度值(QoS Class Identifier,QCI)、分配和保留优先级(Allocation and Retention Priority,ARP)、保证比特速率(Guaranteed Bit Rate,GBR)、最大比特速率(Maximum Bit Rate,MBR)、5G QoS等级标识(5G QoS Indicator,5QI)、保证流比特率(Guaranteed Flow Bit Rate,GFBR)、最大流比特率(Maximum Flow Bit Rate,MFBR)、通知控制notification control等中的一项或者多项,其具体定义可以参考3GPP TS 23.203标准及3GPP TS 23.501标准,此处不再赘述。传输通路的QoS参数信息可以但不限于包含传输通路的QCI、ARP、GBR、MBR、5QI、GFBR、MFBR、notification control等中的一项或者多项,其具体定义可以参考3GPP TS 23.401标准及3GPP TS 23.501标准。需要说明的是,在第一数据流的传输通路的QoS参数信息中还可以包含第一数据流的QoS参数信息。本领域的技术人员可以理解,在某些场景下,第一数据流的传输通路的QoS特征信息可以大致推导第一数据流的QoS特征信息。具体地,应用于EN-DC场景,第一数据流的传输通路可以为E-RAB,在该传输通路中可以传输多个SDF,该E-RAB中的SDF的QoS参数可以大致相近或者相同。具体地,应用于MR-DC with NGC,第一数据流的传输通路可以为PDU Session,在该传输通路中可以传输多个QoS flow,该场景下,QoS flow的QoS参数可以与PDU Session级别的QoS参数不同。定时器时长可以由第二节点根据第一数据流的传输通路的QoS参数信息确定。例如,对于QoS参数信息所指示的包时延预算Packet Delay Budget、资源类型、优先级等级、包错误丢失率、ARP、MBR、AMBR、GFBR、MFBR等参数中的一项或者多项来确定定时器时长。
在第二种可能的实施方式中,第一节点可以获得传输通路和/或第一数据流的特征信息,传输通路和/或第一数据流的特征信息可以包含但不限于传输通路的标识信息和传输通路的预处理规则信息,预处理规则信息至少包含定时器信息,即定时器信息由核心网确定并向第一节点指示。第一节点直接根据预处理规则信息确定定时器时长。
第三种:根据分割承载的特征信息确定定时器的时长。
针对该种确定定时器时长的方法,具体实现过程如下:
具体地,UE与第一节点和第二节点建立双连接,并建立第一无线承载。第一无线承载可以为MCG split bearer或者SCG split bearer。第一节点确定应用到第一无线承载的第一定时器时长,例如,根据第一无线承载的包转发处理方式、QoS特征等确定。
S502:向用户设备发送定时器的时长。
具体地,第一节点向用户设备发送携带有定时器时长信息的消息。
此外,除了向用户设备发送定时器时长信息,还可以向用户设备发送启动和/或停止定时器的触发条件。
S405:如果在第一传输支路上对第一数据执行第一操作,启动定时器。
具体地,在第一传输支路上对第一数据执行第一操作即为定时器的触发条件。该触发条件可以是由第一节点向用户设备发送,也可以是用户设备本地保存。
具体地,第一操作可以包括三种可能的实现方式,具体的实现方式可参见上一实施例中的描述。
S406:当定时器计时结束时,判断在第二传输支路上是否对第二数据执行第二操作;若是,执行S407;若否,执行S408。
具体地,第二操作可以包括三种可能的实现方式,具体的实现方式可参见上一实施例中的描述。
S407:重置定时器。
具体地,当定时器计时结束时,若在第二传输支路上已对第二数据部分执行第二操作,此时停止定时器。即为停止定时器的触发条件。该触发条件可以是由第一节点向用户设备发送,也可以是用户设备本地保存。
S408:指示第二传输支路的较低层协议栈对第二数据执行第三操作。
具体地,第三操作可以包括两种可能的实现方式,具体的实现方式可参见上一实施例中的描述。
S409:指示第二传输支路的较低层协议栈对第二数据执行第四操作。
具体地,第四操作至少可以包括但不限于是以下两种实现方式:
第一种,第四操作可以是将第二数据的备份传输到第一传输支路。
具体地,UE可以将第二数据的备份分配至第一传输支路进行传输。例如,将第二数据的备份传送至第一传输支路的较低层协议栈。具体地,第二数据的备份可以为PDCP层的缓存中存储的第二数据。
第二种,第四操作还可以是将第二数据的备份传输到第三传输支路。
具体地,UE可以建立对应于分割承载的第三传输支路的各层协议栈,该各层协议栈至少包括PDCP层、RLC层和MAC层,并将第二数据的备份分配至第三传输支路的较低层协议栈进行传输,该较低层协议栈包括该第三传输支路的RLC层和/或MAC层。例如,将第二数据传送至第三输支路的较低层协议栈。具体地,第二数据的备份可以为PDCP层的缓存中存储的第二数据。其中,第三节点可以是网络设备,例如但不限于是eNB、gNB、TRP、cell、CU、DU等。
实施本发明实施例可以在用户设备分割承载的上行数传输中,当UE分别向两个传输支路分配了预处理的数据,因某一条传输支路因为信道质量恶化而无法成功传输时,UE可以及时地调整传输策略,由定时器控制两条传输支路的传输时差,对该条传输通路 上的数据执行第三操作,防止数据长时间拥塞在传输质量较差的传输支路上,提升用户体验。进一步的,在执行第三操作后,还可以对第二数据执行第四操作,将第二数据的备份传输至其他可传输数据的传输支路,保证数据正常传输到对端。
