如图2所示,本申请实施例提供一种数据处理方法,应用于网络侧设备,包括:
步骤201、网络侧设备的第一协议层对数据包进行第一处理,所述第一处理包括以下至少一项:数据分流相关处理;数据聚合相关处理;
其中,所述第一协议层位于空口接入技术协议层之上。
该实施例中,所述网络侧设备例如以下任意一项或者多项:核心网设备、接入网设备、其它网络节点等。所述第一协议层可以设置在所述网络侧设备的协议层之中,但是位于空口接入技术协议层之上,用于对终端的数据进行集中管控。所述空口接入技术协议层例如:RAN节点的协议层、无线网络通信(WiFi)接入点(Access Point,AP)协议层等,所述空口接入技术协议层还可以是其他空口接入技术节点的协议层,在此不做限定。
例如:所述第一协议层可以设置在核心网设备,例如UPF或者其他核心网节点,所述第一协议层可以位于网际互连协议(Internet Protocol,IP)层之下,基站的协议层之上,如图3所示;所述第一协议层可以对数据包在两条或者多条传输路径中进行分流相关处理和/或聚合相关处理。
所述第一协议层也可以设置在RAN的集中节点或者锚(anchor)节点,位于RAN的协议层之上,用于对数据包在两条或者多条传输路径中进行分流相关处理和/或聚合相关处理。
所述第一协议层也可以设置在其它网络节点,且位于RAN的协议层之上,用于对数据包在两条或者多条传输路径中进行分流相关处理和/或聚合相关处理。
该实施例中,所述第一协议层为新增的用于进行数据分流相关处理和/或数据聚合相关处理的协议层,该协议层的名称不做限定,例如可以是双协议栈层(Dual Stack Lower Layer,DSLL)。
需要说明的是,本申请的实施例中,不限定所述第一协议层在网络侧设备的位置,仅需要位于空口接入技术协议层之上。所述第一协议层可以执行数据分流相关操作,并将分流数据传输到多条传输路径对应的空口接入节点;所述第一协议层也可以对接收的多条传输路径数据执行数据聚合相关处理,并根据需要将处理后的数据向高层递交,即所述第一协议层既可以作为数据发送端,也可以作为数据接收端。
需要说明的是,在终端同样设置所述第一协议层,从而与网络侧设备进行数据交互。第一协议层设置在空口接入技术协议层之上。终端可以在第一协议层进行数据聚合相关处理和/或数据分流相关处理。
例如:对于下行数据,网络侧设备作为数据发送端,终端作为数据接收端,网络侧设备的第一协议层对待发送数据进行数据分流相关处理,并将处理后的数据分别发送给不同的传输路径(例如gNB1或者gNB2),数据通过不同传输路径到达UE侧。终端对接收的数据进行数据重复检测、重排序等处理并递交高层。
再例如:对于上行数据,终端作为数据发送端,网络侧设备作为数据接收端,终端的第一协议层对待发送数据进行数据分流相关处理,并将处理后的数据分别发送给不同的传输路径对应的L2协议层,传输给不同的网络节点(例如gNB1或者gNB2),数据通过不同传输路径到达网络侧。网络侧设备对接收的数据进行数据重复检测、重排序等处理并递交高层。
本申请的实施例,在网络侧设备设置第一协议层,所述第一协议层位于空口接入技术协议层之上。所述第一协议层用于对数据进行数据分流相关处理和/或数据聚合相关处理,使得网络侧设备与终端在进行数据分流和接收时可以更灵活的操作,能够提升数据的传输效率和业务体验,在增强数据传输效果的基础上同时提升了系统效率。
可选的,所述第一协议层可以仅针对需要分流的协议数据单元(Protocol Data Unit,PDU)会话(session)或者服务质量(Quality of Service,QoS)流(flow)或者承载进行配置出现,非分流的PDU session/QoS flow/承载不出现该协议层或者不配置该协议层;或者,所述第一协议层也可以统一配置出现,针对分流的PDU session/QoS flow/承载的数据与非分流的PDU session/QoS flow/承载的数据执行不同的操作,以适应不同的传输需求。
可选的,所述第一协议层可以独立设置,与L2子层(sub-layer)例如分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)、服务数据适应协议(service data adaption protocol,SDAP)等进行协同工作,在不影响L2 sub-layer的基础上设计新的第一协议层,此种设置方式对协议层影响较小。
可选的,所述第一协议层可以与L2 sub-layer例如PDCP、SDAP等进行重构,例如PDCP和DSLL层如果都有各自的序列号(Sequence Number,SN),均执行重排序和重复检测等功能则有一些重复和效率低下的缺点,可以考虑联合设计,类似的,SDAP进行的QoS flow到无线承载(Radio Bearer,RB)的映射,该功能在引入所述第一协议层之后,可以进行联合设计。
需要说明的是,本申请实施例的第一协议层进行数据分流相关处理和/或数据聚合相关处理,可以应用于双连接场景或者更多连接场景,在此不做限定。
作为一个可选实施例,所述数据分流相关处理,包括以下至少一项:
为数据包添加头部结构(header);
为数据包选择路由路径;
根据路由路径发送数据包。

根据所述第一配置信息,对所述数据包进行处理;
其中,所述第一配置信息包括以下至少一项:

服务质量QoS流与数据包的对应关系;例如哪些数据属于一个QoS flow;
无线承载RB与数据包的对应关系,例如哪些数据属于一个RB。
该实施例中,所述第一配置信息可以由控制面配置,例如:网络侧设备是核心网节点,在核心网和UE之间的控制面可以使用非接入层(Non-access stratum,NAS)信令配置所述第一配置信息,这样可以在核心网和UE之间对于数据发送端和接收端进行同步配置,以便于后续数据处理可以双方统一无误操作;在RAN节点和UE之间的控制面可以使用RRC过程配置所述第一配置信息,使RAN节点和UE之间对于数据的处理一致。
网络侧设备的第一协议层可以基于所述第一配置信息对数据包进行处理,例如:根据所述第一配置信息能够知道是否需要为数据包添加头部结构、根据所述第一配置信息为数据包选择路由路径,根据所述第一配置信息发送数据包等等。比如:为所有经过该第一协议层的数据包均添加头部结构、为指示需要添加头部结构的数据包添加头部结构、为具有按序递交需求的数据包添加头部结构等,所述第一协议层也可以基于所述第一配置信息中的一项或者多项信息的组合确定是否需要为数据包添加头部结构,例如:为经过第一协议层且具有按序递交需求的数据包添加头部结构。在此不一一列举。
所述第一协议层还可以根据所述第一配置信息确定哪些数据属于一个QoS flow、哪些数据属于一个RB,从而基于不同的粒度为数据包添加头部结构。
作为一个可选实施例,所述为数据包添加头部结构,包括:
基于第一粒度为所述数据包添加头部结构;
其中,所述第一粒度包括以下至少一项:
RB粒度;
QoS流粒度。
该实施例中,网络侧设备可以在第一协议层基于RB粒度为所述数据包添加头部结构,也可以基于QoS流粒度为所述数据包添加头部结构。例如:根据RB与数据包的对应关系,针对每个RB包含的数据包各自添加头部结构;或者,根据QoS流与数据包的对应关系,针对每个QoS流包含的数据包各自添加头部结构。
可选的,在为数据包添加头部结构时,可以基于所述第一粒度并根据所述第一配置信息为数据包添加头部结构,例如:针对经过第一协议层的数据包,基于每个RB包含的数据包各自添加头部结构;或者,针对每个RB包含的数据包,针对具有按序递交需求的数据包添加头部结构;或者,对于经过所述第一协议层、且有多路径选择需求、且需要按序递交的QoS流,基于QoS flow为数据包添加头部结构。
可选的,所述数据包的头部结构携带以下信息中的至少一项:
1)序列号SN;数据包的接收端可以基于SN对数据包进行重排序、重复检测等操作。
2)数据包对应的QoS流标识ID;用于指示数据包所在的QoS flow,例如:在基于QoS流粒度为数据包添加头部结构时可以携带该QoS flow ID,数据接收端可以基于QoS flow ID对数据包进行重排序、重复检测等操作。
3)RB标识ID;用于指示数据包所在的RB,例如:在基于RB粒度为数据包添加头部结构时,可以携带该RB ID,数据接收端可以基于RB ID对数据包进行重排序、重复检测等操作。
4)QoS反向映射(reflective)比特信息。
可选的,所述QoS反向映射比特信息包括以下至少一项:

该实施例中,所述数据包的头部结构中可以携带SN。网络侧设备可以按照第一顺序为所述数据包分配SN。例如:为所有经过所述第一协议层的数据包添加头部结构,并按照各个数据包的到达或者发送顺序进行SN顺序分配;为具有按序递交需求的数据包添加头部结构,并按照所述具有按序递交需求的数据包的到达或者发送顺序进行SN顺序分配;为需要动态路由的数据包添加头部结构,并按照所述需要动态路由的数据包的到达或者发送顺序进行SN顺序分配;基于RB粒度为数据包添加头部结构时,按照每个RB内的数据包的到达或者发送顺序进行SN顺序分配;基于QoS流粒度为数据包添加头部结构时,按照每个QoS流内的数据包的到达或者发送顺序进行SN顺序分配。
可选的,由于PDCP层也能够执行分配SN的操作,但是PDCP层只能进行自己单条路径传输的SN分配和重复检测/重排序,并不能处理两条路径的顺序,PDCP实体位于每条路径内部,不能处理其它路径数据。为了避免重复操作导致资源浪费,可以将所述第一协议层与PDCP层进行联合设计,在所述第一协议层分配SN的情况下,可以删除PDCP层的分配SN的操作。需要说明的是,对于所述第一协议层独立设计的情况,无需删除PDCP层的分配SN的操作,这样对当前的协议层影响较少,实现更便捷。

该实施例中,QoS流到RB的映射操作和/或IP流到QoS流的映射操作也可以在所述第一协议层执行。由于当前的SDAP层也能够执行上述映射操作,在该实施例中将上述映射操作设置在第一协议层内执行,例如:网络侧设备作为数据发送端,在第一协议层增加的数据包头部结构中携带QoS flow ID和相应的NAS Reflective QoS比特,表明该QoS flow的上行也支持相同的IP流到QoS flow ID的映射关系,和或携带相应的AS reflective QoS比特,表明该QoS flow的上行也支持相同的QoS flow到RB的映射关系,这样在第一协议层完成SDAP的映射功能。对于数据接收端,可以根据接收的NAS reflective QoS比特和/或AS reflective QoS比特指示,按照下行相同的IP流到QoS flow的映射关系,处理上行映射,或者按照下行相同的QoS flow到RB的映射关系,处理上行映射。
可选的,由于当前的SDAP层能够执行QoS流到RB的映射操作、IP流到QoS流的映射,为了避免映射操作的重复执行导致资源浪费,可以将所述第一协议层与SDAP层进行联合设计,可以删除SDAP层的QoS流到RB的映射操作,和/或删除SDAP层的IP流到QoS流的映射操作。需要说明的是,对于所述第一协议层独立设计的情况,无需删除SDAP层数据映射操作,这样对当前的协议层影响较少,实现更便捷。

该实施例中,在第一协议层读取数据包的头部结构,获得数据包的SN、QoS流ID和/或RB ID,可以基于RB粒度或者QoS流粒度并结合数据包的SN对数据包进行重排序。例如:基于RB粒度:对于每个RB,基于该RB内的数据包的SN进行重排序;基于QoS流粒度:对于每个QoS流,基于该QoS流内的数据包的SN进行重排序。
作为一个可选实施例,所述对数据包进行重排序,包括以下至少一项:
在接收数据包的情况下,按照SN升序对接收的数据包进行排序,若发生接收缺口,则启动定时器;
在定时器启动的情况下,记录所述定时器的启动时刻之前接收的SN最大值或SN最大值加1;

在定时器启动的情况下,若记录的SN最大值或者SN最大值加1之前的数据包全部按序递交,则停止所述定时器;
在停止所述定时器的情况下,若接收序列中再次发生接收缺口,则继续启动时器;
在定时器超时之后,若未全部接收到所述接收缺口中的数据包,则停止等待所述接收缺口中的数据包,并将其它数据包按照SN升序顺序向高层递交。
该实施例中,重排序可以采用重排序窗口(T-reordering)操作,对相同流ID或者RB ID的数据按照SN顺序进行排序,按序且连续接收的数据直接按照SN升序递交高层即可。对于出现的接收缺口(gap),启动T-reordering定时器,等待对应的时长,例如:接收到的数据包对应的SN为1、2、5,2和5之间出现gap;可以记录定时器启动前接收到的数据包的SN最大值或SN最大值加1,例如:记录5或者6;和/或,在等待定时器对应的时长的期间,接收到的数据包不满足按序递交,则对这部分数据包进行缓存,比如在等待期间接收到的数据包的SN为6、7,则缓存这部分数据包;和/或,在等待定时器对应的时长的期间,若记录的SN最大值或者SN最大值加1之前的数据包全部接收且按序递交,则可以停止定时器,例如:在等待期间接收到3、4,满足了按序递交,则可以停止定时器;和/或,在定时器停止后,若再次发现了gap,则继续启动定时器,例如:在按序递交完数据包7后,接收到数据包9,出现gap,则继续启动定时器,重复上述等待的步骤;在定时器超时后,若仍未全部接收到gap中的数据包,则停止等待未接收的数据包,将其它数据按序递交,例如:定时器超时后仍未接收到数据包8,则将其它的数据包如9、10等按照顺序递交高层。
作为一个可选实施例,所述方法还包括:
接收终端发送的能力信息;
其中,所述能力信息包括以下至少一项:
第五指示信息,用于指示所述终端支持独立设置的第一协议层,或者,支持与L2重构的第一协议层;
第六指示信息,用于指示所述终端支持的第一协议层的SN粒度信息;
第七指示信息,用于指示所述终端是否支持第一协议层或者分流服务。
该实施例中,终端可以向网络侧设备上报UE能力,可以作为单独的能力或者作为与多流功能绑定的能力进行上报。在所述能力信息中可以指示终端支持独立设置的第一协议层,或者支持与L2重构之后的协议层,所述能力信息中还可以指示终端支持的第一协议层的SN粒度信息等。网络侧设备需要详细知道UE支持该新的第一协议层功能的情况,才能进行后续配置和使用操作。
可选的,所述方法还包括:向所述终端发送第二配置信息,所述第二配置信息包括所述第一协议层的配置信息。
该实施例中,网络侧设备可以基于终端的能力配置第一协议层,例如:网络侧可以通过控制面(Control Plane,CP)的配置过程,对重构的第一协议层以及相关层进行配置,由于既涉及核心网和UE之间的配置,也关联RAN和UE之间的配置,因此对于核心网与UE之间的配置使用NAS过程配置,对于RAN和UE之间的配置使用RRC过程配置。可选的,核心网节点和RAN节点需要对配置信息达成一致,核心网节点可以在向RAN节点发送的N2信令中携带新的信息,告知RAN节点配合进行所述第一协议层的配置。
可选的,所述第二配置信息还包括以下至少一项:

第九指示信息,用于指示删除SDAP层的IP流到QoS流的映射操作;
第十指示信息,用于指示删除PDCP层的分配SN的操作;
第十一指示信息,用于指示修改PDCP层的安全操作输入参数。
该实施例中,对于所述第一协议层与L2层重构的情况,可以在第二配置信息中指示相关L2层删除重复的操作,例如:第一协议层执行QoS流到RB的映射操作和/或IP流到QoS流的映射操作,则可以删除SDAP层的QoS流到RB的映射操作和/或IP流到QoS流的映射操作;第一协议层执行分配SN的操作,则可以删除PDCP层的分配SN的操作,避免了重复操作造成的开销和资源浪费。
其中,所述第一协议层基于QoS flow进行SN分配时,其分配粒度与传统的PDCP分配SN的粒度有差别,此时可以修改PDCP层的操作,例如:PDCP层执行安全操作时,输入参数由RB ID+SN值改为QoS flow+SN值,这样PDCP层也可以直接使用DSLL的SN进行操作,且PDCP层不需要进行重排序功能,PDCP实体的重复检测功能较简单还可以继续进行,以应对RAN侧的重复传输。
作为一个可选实施例,所述方法还包括以下一项:
在所述第一协议层为数据发送端的情况下,接收终端发送的第三信息;
在所述第一协议层为数据接收端的情况下,向终端发送第三信息;
其中,所述第三信息包括以下至少一项:
数据包丢失信息;
网络质量信息;

复制操作激活请求信息。
该实施例中,在所述网络侧设备是数据发送端的情况下,数据接收端可以向网络侧设备进行控制(control)PDU的发送,control PDU可以包括接收情况反馈,例如哪些数据包丢失,也可以包括链路情况反馈,例如链路质量变好/变差,也可以是请求数据发送端进行路径切换,或者请求数据发送端激活复制传输等。
下面针对第一协议层独立设置和第一协议层与L2层重构的两种情况,分别说明本申请实施例的数据处理方法的实现过程。
示例一:第一协议层独立设置
该实施例中,以所述第一协议层独立设置为,假设第一协议层位于核心网的UPF节点,且位于IP层之下,gNB的协议层之上,对IP数据包在两条或者多条传输路径之中进行分流复制路由接收等处理,如图3所示。需要说明的是,图3所示的第一协议层的设置位置并不是唯一的实现方式,还可以有其它的设置方法,例如第一协议层位于其它核心网节点或者RAN侧的anchor基站上,对多个基站的数据进行统一管理管控等,本申请实施例并不限制各种合理的实现方式。
如图3所示,第一协议层主要负责对UE的两条或者多条路径的数据进行管理和控制,分为发送端功能和接收端功能,其中发送端功能主要负责数据分流相关处理,如数据分发、路由机制、增加头部、复制传输控制等,接收端功能主要负责数据聚合相关处理,如数据接收、重复检测、重排序、按序递交等。
图3中以两条传输路径举例,路径1可以是通过gNB1的4G、5G、6G空口传输路径,或者是其它无线接入技术RAT、卫星路径、Wifi路径等,这里并不限制,路径2也可以是通过gNB2的4G、5G、6G空口传输路径,或者是其它RAT、卫星路径、Wifi路径等,路径1和路径2可以是相同运营商也可以属于不同运营商,具体的传输路径可以是2条甚至更多条。
该实施例中,将需要的新功能尽量在所述第一协议层实现,而其它协议层,例如不同路径的中的传输层PDCP、SDAP等使用传统的协议版本,能够避免协议层升级和改动造成的影响。
所述第一协议层的发送端具有如下的功能和处理的至少一项:
以网络侧设备是数据发送端为例,终端是数据接收端。所述第一协议层的发送端处理下行数据:由业务层实体应用(Application)产生的数据经过传统的传输层协议用户数据报协议(User Datagram Protocol,UDP)/传输控制协议(Transmission Control Protocol,TCP)/快速UDP网络连接(Quick UDP Internet Connections,QUIC)/互联网协议(Internet Protocol,IP)层传输之后,到达所述第一协议层,所述第一协议层的发送端对数据进行分发和处理,发送给不同的传输路径,例如图3中的gNB1或者gNB2,数据通过不同路径到达UE侧。
以网络侧设备是数据接收端为例,终端是数据发送端。所述第一协议层的发送端处理上行数据,由业务层实体Application产生的数据经过传统的传输层协议UDP/TCP/QUIC/IP层传输之后,到达所述第一协议层,所述第一协议层的发送端对数据进行分发和处理,发送给不同的传输路径对应的L2协议层,传输给不同的网络节点,例如gNB1或者gNB2,数据通过不同路径到达网络侧。
下面对所述第一协议层的发送端的功能进行说明,以所述第一协议层表示为DSLL为例,所述发送端可以是网络侧设备也可以是终端,这里并不区分UE/网络侧,因此下面描述同时适用于UE和网络侧作为发送端时的数据处理过程,具体包括以下操作中的至少一项:
(1)所述第一协议层的发送端按照需求或者配置,为数据包增加头部结构(DSLL header),DSLL header中至少包含DSLL SN,携带该SN的目的是为了接收端的重复检测和重排序等功能。
DSLL层为数据包添加header,可以包括以下至少一项:
1)为所有经过DSLL层的数据包添加header,例如:对所有经过DSLL层传输的数据,也就是经过多流选择的数据,统一增加DSLL header,并按照数据包的到达或者发送顺序分配SN。
2)为需要按序递交的数据包添加header,例如:对所有经过DSLL层传输且有按序递交需求的数据统一增加DSLL header,并按照数据包的到达或者发送顺序分配SN。
3)为需要进行动态路由的数据包添加header,例如:对所有经过DSLL层传输且有动态路由需求的数据统一增加DSLL header,并按照数据包的到达或者发送顺序分配SN。
DSLL层为数据包分配SN的粒度可以包括以下至少一项:
a)基于RB粒度为数据包分配SN,例如:对所有经过DSLL层传输的数据,按照每个RB粒度各自增加DSLL header,并按照数据包在该RB内到达或者发送顺序分配SN。RB可以是多个QoS flow的组合,这些QoS flow具有相同或者近似的QoS属性,或者这些QoS flow的数据包有顺序关联等。
b)基于QoS flow粒度为数据包分配SN,例如:对所有经过DSLL层传输的数据,按照每个QoS flow各自增加DSLL header,并按照数据包在该QoS flow内到达或者发送顺序分配SN。
在为数据包添加头部结构时,可以按照上述方式以及上述粒度的组合为数据包添加头部结构,例如:可以对经过DSLL层、有多路径选择需求、需要按序递交的QoS flow,才增加基于QoS flow的DSLL header,并在该QoS flow内部对数据进行SN顺序分配。
可选的,为了更好的区分数据包,可以在DSLL头部结构中,增加QoS flow ID或者RB ID等信息,以区分不同的数据流和SN顺序。
可选的,可以通过控制面配置第一配置信息,指示哪些数据属于一个QoS flow或者RB,和/或哪些数据包需要动态路由,和/或哪些数据包需要按序递交等。例如:在核心网和UE之间的控制面可以使用NAS信令配置所述第一配置信息,这样可以在核心网和UE节点之间对于DSLL发送端和接收端进行同步配置,以便于后续数据处理可以双方统一无误操作。
(2)所述第一协议层的发送端按照需求或者配置,对待发送数据进行分流(split)操作,选择合适的路由,进行后续的数据传输。例如:对于增加了头部结构的数据,路由选择可以相对动态,可以实时决定由路径1还是路径2传输,可以基于实时链路质量情况选择更优路径,或者基于网络负荷和拥塞情况选择更优路径等;对于没有头部结构的数据,路径选择更加静态,尽量选择当前路径,避免路径转换带来的接收乱序情况。
(3)所述第一协议层的发送端按照需求或者配置,对待发送数据进行复制(duplication)操作的激活和去激活等,选择合适的路由,进行后续的数据传输。例如:对于增加了头部结构的数据,duplication激活选择可以相对灵活,可以实时决定是否同时由路径1和路径2传输,可以基于业务QoS,或者基于网络情况选择是否复制传输等;对于没有头部结构的数据,则需要避免开启复制传输,尽量选择当前路径,避免复制带来的接收重复情况。
所述第一协议层的接收端具有如下的功能和处理的至少一项:
以网络侧设备是数据接收端为例,终端是数据发送端。所述第一协议层的接收端处理上行数据:数据包通过不同路径(例如gNB1或者gNB2)到达所述第一协议层,经过处理之后,向更高层传递。所述第一协议层的接收端(即网络侧设备)对数据进行必要的重复检测、重排序、去除头部等操作,根据需要按顺序向高层递交数据。
以UE为数据接收端为例,网络侧设备是数据发送端。所述第一协议层的接收端处理下行数据,数据包通过不同路径(例如gNB1或者gNB2)到达UE的第一协议层,经过处理之后,向更高层传递。所述第一协议层的接收端(即终端)对数据进行必要的重复检测,重排序、去除头部等操作,根据需要按顺序向高层递交数据。
下面对所述第一协议层的接收端的功能进行说明,以所述第一协议层表示为DSLL为例,所述接收端可以是网络侧设备也可以是终端,这里并不区分UE/网络侧,因此下面描述同时适用于UE和网络侧作为接收端时的数据处理过程,具体包括以下操作中的至少一项:
DSLL接收端,对于没有设置头部结构的数据,只能进行透传处理,直接递交;
DSLL接收端,对于有头部结构的数据,可以按照配置读取不同的信息位,获得RB ID/QoS flow ID等信息,区分不同的RB和/或QoS flow流,再按照SN对数据包进行重复检测处理和重排序等操作。其中,重复检测处理包括:将QoS流ID相同且SN相同的数据认为是重复数据,和/或RB ID相同且SN相同的数据认为是重复数据,可以删除再次接收的重复数据。
重排序可以采取T-reordering窗口操作,对QoS流ID相同的数据按照SN顺序进行排序,按序且连续接收的数据,直接按照SN升序递交高层即可。对于出现的接收gap,启动T-reordering定时器,等待对应的时长;在等待期间,gap之后的数据进行缓存,直至gap处被正确接收,按SN升序递交高层;或者,若定时器超时之后gap数据仍旧没有接收,则放弃gap处的数据等待,将之后的连续数据按照SN升序递交高层。
可选的,DSLL接收端,还可以向DSLL发送端进行control PDU的发送(即发送所述第三信息),control PDU可以包括接收情况反馈,例如哪些数据包丢失;也可以包括链路情况反馈,例如链路质量变好/变差;也可以是请求发送端进行路径切换,或者请求发送端激活复制传输等。
在该实施例中,所述第一协议层独立设计,可以完全兼容相关技术中的协议,不用对相关技术中的协议进行任何修改和升级,即可在UE和网络节点之间基于所述第一协议层进行多流数据的控制和传输,以达到灵活路由和按序递交等需求。
示例二:第一协议层与L2联合设计
该实施例中,将新增的第一协议层和传统的L2协议层功能进行联合考虑,以更优更高效的方式,进行多流数据控制和传输。假设第一协议层位于核心网的UPF节点,且位于IP层之下,gNB的协议层之上,对IP数据包在两条或者多条传输路径之中进行分流复制路由接收等处理,如图4所示,所述第一协议层执行SDAP以及PDCP层中的部分功能,如:QoS flow到RB的映射、IP流到QoS流的映射、分配SN等,SDAP以及PDCP层中的重复功能删除。需要说明的是,图4所示的第一协议层的设置位置并不是唯一的实现方式,还可以有其它的设置方法,例如第一协议层位于其它核心网节点或者RAN侧的anchor基站上,对多个基站的数据进行统一管理管控等,本申请实施例并不限制各种合理的实现方式。
参照示例一中关于第一协议层的功能,为了满足路由和接收重复检测/按序递交等基本的多流功能操作,第一协议层发送端需要按照QoS flow或者RB粒度为数据包按序添加SN,并在接收端按照SN顺序进行重排序和重复检测功能,而这些功能与传统的L2协议中SDAP和PDCP的功能有一定的交叠,如果能重构设计,则将具有更高效的处理效果,重构设计的处理包括以下至少一项:
(A)传统的SDAP层的主要功能是将传输需求相同或者相近的QoS flow映射到对应的RB上,并根据需要在SDAP header中携带QoS flow ID和reflective QoS标记,以完成QoS flow的区分,节省核心网配置IP流到QoS flow流映射的信令,节省RAN配置QoS flow流RB映射的信令。在引入所述第一协议层之后,这些功能都可以考虑由所述第一协议层来完成,进而去掉每条路径上的SDAP子层,具体做法包括如下至少一项:
a1)网络侧设备作为数据发送端,对于下行数据,在所述第一协议层中为数据包添加头部结构header,header中携带QoS flow ID和相应的NAS Reflective QoS比特,表明该QoS flow的上行也支持相同的IP流到QoS flow ID的映射关系,和/或header中携带相应的AS reflective QoS比特,表明该QoS flow的上行也支持相同的QoS flow到RB的映射关系。这样,SDAP功能在所述第一协议层基本完成,在RAN侧只需要进行简单的实现,将QoS flow映射到对应的RB里,即可,映射方式可以基于基站实现或者配置;
终端作为数据接收端,对于下行数据,UE侧的第一协议层可以根据接收的数据包头部结构中携带的NAS reflective QoS比特和/或AS reflective QoS比特指示,按照下行相同的IP流到QoS flow的映射关系,处理上行映射,或者按照下行相同的QoS flow到RB的映射关系,处理上行映射。
a2)终端作为数据发送端,对于上行数据,UE侧的第一协议层为数据包添加头部结构,header中携带对应的QoS flow ID,用于区分不同的QoS流,并按照网络侧配置的QoS flow到RB的映射方式进行映射,即可完成传统SDAP的基本功能;
网络侧设备作为数据接收端,对于上行数据,网络侧设备的第一协议层根据接收到的数据包的header中的QoS flow ID,将数据进行处理,并根据QoS flow进行转发。
a3)网络侧设备作为数据发送端,对于下行数据,网络侧的第一协议层为数据包添加的header中携带RB ID和相应的Reflective QoS比特,表明上行也支持相同的IP流到RB ID的映射关系。传统SDAP的功能在所述第一协议层基本完成,在RAN侧每个RB ID的数据对应一个PDCP实体。
终端作为数据接收端,对于下行数据,UE侧的第一协议层可以根据接收的数据包的header携带的reflective QoS比特指示,按照下行相同的IP流到RB的映射关系,处理上行映射。
a4)终端作为数据发送端,对于上行数据,UE侧的第一协议层为数据包添加的header中携带对应的RB ID,用于区分不同的RB流,并按照网络侧配置的QoS flow/IP流到RB的映射方式进行映射,即可完成传统SDAP的基本功能;
网络侧设备作为数据接收端,对于上行数据,网络侧的第一协议层根据接收到的数据包的header携带的RB ID,将数据进行处理,并进行转发。
(B)传统的PDCP层发送端也具有添加PDCP header和分配SN功能,接收端根据SN进行重复检测和重排序等,但是在这种架构下,PDCP层只能进行自己单条路径传输的SN分配和重复检测/重排序,并不能处理两条路径的顺序,这与PDCP实体所处的位置有关,PDCP实体位于每条路径内部,不能处理其它路径数据。该实施例中,将第一协议层和PDCP进行联合设计,可以进一步提升效率,具体做法包括如下至少一项:
b1)当所述第一协议层基于每个RB进行SN分配时,其分配粒度与传统的PDCP是一样的,因此可以考虑节省PDCP层的再次分配SN的操作。对于PDCP的安全操作,例如加密解密、完整性保护和完整性验证,可以直接使用所述第一协议层分配的SN进行,且PDCP层不需要进行重排序功能,因为所述第一协议层分配的连续SN被分流到两条路径的PDCP实体,例如:其中一个PDCP实体的数据SN本身可能是1,3,5,7……,另一个PDCP实体的数据SN本身可能是2,4,6,8……,PDCP实体本身不具备排序的基础和必要,而单个PDCP实体的重复检测功能因为较简单还可以继续进行,以应对RAN侧的重复传输。
可选的,对于第一协议层的control PDU,可以和数据一样分配SN,也可以不分配SN,如果分配了SN则在PDCP按照数据一起处理,例如安全操作;如果没有分配SN,则跳过相关需要SN处理的操作即可。
在该实施例中,SN分配和重排序功能被上移到所述第一协议层执行,可以去除PDCP的重复功能,能降低处理效率和头开销。
b2)当所述第一协议层基于QoS flow进行SN分配时,其分配粒度与传统的PDCP有差别,此时可以修改PDCP层的操作,例如安全操作:输入参数由RB ID+SN值改为QoS flow+SN值,这样PDCP层也可以直接使用DSLL的SN进行操作,且PDCP层不需要进行重排序功能。PDCP实体的重复检测功能因为较简单还可以继续进行,以应对RAN侧的重复传输。所述第一协议层的control PDU的处理方式参见上述b1),这里不做赘述。
在该实施例中,所述第一协议层与传统的L2联合设计,重构了传统的L2子层,例如SDAP和PDCP。因此需要增强与传统系统的兼容性,例如:在配置阶段,RAN节点需要知道这是针对增强的多流传输操作,是增强的第一协议层实体,需要配合它配置去除SDAP和增强之后的PDCP实体中的重复功能。该方法能够显著提升处理效率和降低开销。
示例三:对于上述示例一和示例二,新增的第一协议层的相关信息需要进行配置。
该实施例是针对所述第一协议层的两种设置方式相关的配置过程、切换和重配置等重要过程进行说明。
可选的,对于所述第一协议层的支持,需要UE能力上报,例如作为单独的能力或者与多流功能绑定的能力进行上报。上报的能力可以包括:终端支持独立设置的第一协议层,还是与L2重构之后的第一协议层,和/或终端支持的第一协议层的SN粒度信息等。网络侧需要详细知道UE支持的第一协议层功能的情况,才能进行后续配置和使用操作。
其中,在UE和网络侧设备都支持独立设置的第一协议层功能时,网络侧设备可以通过CP面的配置过程,对独立设置的第一协议层进行配置,由于涉及的是核心网和UE之间的配置,因此可以使用NAS过程进行配置,建立所述第一协议层以及第一协议层内部的细节参数,例如DSLL SN的粒度、SN长度等。在UE和核心网建立起对等的第一协议层,即可按照上述示例一的方式进行数据收发。
在UE和网络侧设备都支持重构的第一协议层功能时,网络侧设备可以通过CP面的配置过程,对重构的第一协议层以及相关层进行配置,由于既涉及核心网和UE之间的配置,也关联RAN和UE之间的配置,因此核心网和UE之间的配置使用NAS过程配置,RAN和UE之间的配置使用RRC过程配置。可选的,核心网控制节点例如AMF还需要和RAN节点的对配置信息达成一致,以实现统一配置,例如:AMF发送给RAN节点的N2信令中,携带新增的信息,告知RAN节点配合进行SDAP和PDCP的重新配置,以配合重构第一协议层。在核心网节点、RAN节点和UE都配置好重构的第一协议层、重构的SDAP、PDCP层之后,即可以按照示例二方式进行数据收发。
如果终端和网络侧设备均可以支持两种第一协议层的设置方式,则网络实现决定配置哪一种。
对于一个UE来说,当前的业务组合中,可能部分业务支持或者建立了分流传输,其余业务不支持或者未建立分流传输,因此在配置时,还需要考虑如何进行区分对待。其中,一种方式是:在配置信息中明确说明哪些业务或QoS flow或RB等经过第一协议层传输,另一些业务采取传统协议栈架构传输;另一种方式是:配置了第一协议层,则需要被处理的数据按照第一协议层的正常流程处理并进行相应的L2处理,而其余数据在第一协议层透传处理,对应的L2也是传统(legacy)方式。通过以上两种方式,可以使传统业务和新业务需求进行共存,并各自处理。
对于第一协议层的重配置:如果要进行第一协议层相关的重配置,可以采用全部重配(full configuration)的方式,即删除旧的实体和状态,重新建立新的实体并从初始化状态开始,此种方式执行简单,但会带来重配置的丢包体验。如果需要克服该缺陷,则需要进一步优化,尽量在配置后能保持配置之前的状态,并延续处理。
对于第一协议层从无到有或者从有到无的重配置情况,由于架构和处理差别太大,优化的可行性较低,可以仅仅在第一协议层内部进行一些参数重配置,可以考虑连续性优化。
如果配置了第一协议层的UE进行切换,当源节点或者目标节点中有一方是不支持所述第一协议层的新功能时,采取full configuration的方式,即删除旧的实体和状态,重新建立新的实体并从初始化状态开始,这种方式操作简单,能够克服版本兼容性影响。当源节点和目标节点都支持相同的第一协议层新功能配置时,可以在切换时考虑进行配置和状态的保持,在第一协议层进行数据恢复或者重建或者数据前传时,将源节点的状态尽量迁移到目标节点侧,这样使得在目标节点侧可以尽可能地延续当前状态,避免任意丢包,达到连续性很好的切换体验。
本申请的实施例,可以应用到NR Uu,也可以扩展到其它不同版本这里并不限定。
本申请的实施例,在终端和网络侧设备设置第一协议层,所述第一协议层位于空口接入技术协议层之上。所述第一协议层用于对数据进行数据分流相关处理和/或数据聚合相关处理,使得网络侧设备与终端在进行数据分流和接收时可以更灵活的操作,能够提升数据的传输效率和业务体验,在增强数据传输效果的基础上同时提升了系统效率。
如图5所示,本申请还提供一种数据处理方法,应用于终端,包括:
步骤501、终端的第一协议层对数据包进行第二处理,所述第二处理包括以下至少一项:数据聚合相关处理;数据分流相关处理;
其中,所述第一协议层位于空口接入技术协议层之上。
该实施例中,所述第一协议层可以设置在终端的协议层,但是位于空口接入技术协议层之上,可以对终端的数据进行集中管控。所述空口接入技术协议层例如:RAN节点的协议层、WiFi AP协议层等,所述空口接入技术协议层还可以是其他空口接入技术节点的协议层,在此不做限定。所述第一协议层可以对数据包在两条或者多条传输路径中进行分流相关处理和/或聚合相关处理。例如:所述第一协议层可以执行数据分流相关操作,并将分流数据传输到多条传输路径对应的空口接入节点;所述第一协议层也可以对接收的多条传输路径数据执行数据聚合相关处理,并根据需要将处理后的数据向高层递交,即所述第一协议层既可以作为数据发送端,也可以作为数据接收端。
需要说明的是,在网络侧设备同样设置所述第一协议层,从而与终端进行数据交互。第一协议层设置在空口接入技术协议层之上。所述网络侧设备例如以下任意一项或者多项:核心网设备、接入网设备、其它网络节点等。所述第一协议层可以设置在所述网络侧设备的协议层的任意位置,但是位于空口接入技术协议层之上。本申请的实施例中,不限定所述第一协议层在网络侧设备的位置,仅需要位于空口接入技术协议层之上。
例如:对于上行数据,终端作为数据发送端,网络侧设备作为数据接收端,终端的第一协议层对待发送数据进行数据分流相关处理,并将处理后的数据分别发送给不同的传输路径对应的L2协议层,传输给不同的网络节点(例如gNB1或者gNB2),数据通过不同传输路径到达网络侧。网络侧设备对接收的数据进行数据重复检测、重排序等处理并递交高层。
对于下行数据,终端作为数据接收端,网络侧设备作为数据发送端,网络侧设备的第一协议层对待发送数据进行数据分流相关处理,并将处理后的数据分别发送给不同的传输路径(例如gNB1或者gNB2),数据通过不同传输路径到达UE侧。终端对接收的数据进行数据重复检测、重排序等处理并递交高层。
本申请的实施例,在终端设置第一协议层,所述第一协议层位于空口接入技术协议层之上。所述第一协议层用于对数据进行数据分流相关处理和/或数据聚合相关处理,使得网络侧设备与终端在进行数据分流和接收时可以更灵活的操作,能够提升数据的传输效率和业务体验,在增强数据传输效果的基础上同时提升了系统效率。
作为一个可选实施例,所述数据分流相关处理,包括以下至少一项:

其中,所述第一配置信息包括以下至少一项:

该实施例中,所述第一配置信息可以由控制面配置,例如:在核心网和UE之间的控制面可以使用NAS信令配置所述第一配置信息,这样可以在核心网和UE之间对于数据发送端和接收端进行同步配置,以便于后续数据处理可以双方统一无误操作;在RAN节点和UE之间的控制面可以使用RRC过程配置所述第一配置信息,使RAN节点和UE之间对于数据的处理一致。
终端的第一协议层可以基于所述第一配置信息对数据包进行处理,例如:根据所述第一配置信息能够知道是否需要为数据包添加头部结构、根据所述第一配置信息为数据包选择路由路径,根据所述第一配置信息发送数据包等等。比如:为所有经过该第一协议层的数据包均添加头部结构、为指示需要添加头部结构的数据包添加头部结构、为具有按序递交需求的数据包添加头部结构等,所述第一协议层也可以基于所述第一配置信息中的一项或者多项信息的组合确定是否需要为数据包添加头部结构,例如:为经过第一协议层且具有按序递交需求的数据包添加头部结构。在此不一一列举。
所述终端还可以再第一协议层根据所述第一配置信息确定哪些数据属于一个QoS flow、哪些数据属于一个RB,从而基于不同的粒度为数据包添加头部结构。
作为一个可选实施例,所述为数据包添加头部结构,包括:
基于第一粒度为所述数据包添加头部结构;
其中,所述第一粒度包括以下至少一项:
RB粒度;
QoS流粒度。
该实施例中,终端可以在第一协议层基于RB粒度为所述数据包添加头部结构,也可以基于QoS流粒度为所述数据包添加头部结构。例如:根据RB与数据包的对应关系,针对每个RB包含的数据包各自添加头部结构;或者,根据QoS流与数据包的对应关系,针对每个QoS流包含的数据包各自添加头部结构。
可选的,在为数据包添加头部结构时,可以基于所述第一粒度并根据所述第一配置信息为数据包添加头部结构,例如:针对经过第一协议层的数据包,基于每个RB包含的数据包各自添加头部结构;或者,针对每个RB包含的数据包,针对具有按序递交需求的数据包添加头部结构;或者,对于经过所述第一协议层、且有多路径选择需求、且需要按序递交的QoS流,基于QoS flow为数据包添加头部结构。
可选的,所述数据包的头部结构携带以下信息中的至少一项:
1)序列号SN;数据包的接收端可以基于SN对数据包进行重排序、重复检测等操作。
2)数据包对应的QoS流标识ID;用于指示数据包所在的QoS flow,例如:在基于QoS流粒度为数据包添加头部结构时可以携带该QoS flow ID,数据接收端可以基于QoS flow ID对数据包进行重排序、重复检测等操作。
3)RB标识ID;用于指示数据包所在的RB,例如:在基于RB粒度为数据包添加头部结构时,可以携带该RB ID,数据接收端可以基于RB ID对数据包进行重排序、重复检测等操作。
4)QoS反向映射(reflective)比特信息。
可选的,所述QoS反向映射比特信息包括以下至少一项:
AS QoS反向映射比特信息,用于指示上行数据支持与下行数据相同的QoS流到RB的映射关系;数据发送端和接收端可以基于该AS QoS反向映射比特信息进行上行和/或下行数据的映射。

该实施例中,在为数据包添加头部结构时,可以在头部结构中携带上述一项或者多项信息,使数据接收端能够读取数据包头部结构的信息位,获得相应信息内容,执行数据聚合相关处理。
作为一个可选实施例,所述方法还包括:
按照第一顺序为数据包分配SN,所述第一顺序包括以下至少一项:

数据包在所述第一协议层的发送顺序;
数据包在RB内的到达顺序;
数据包在RB内的发送顺序;
数据包在QoS流内的到达顺序;
数据包在QoS流内的发送顺序。
该实施例中,所述数据包的头部结构中可以携带SN。终端可以按照第一顺序为所述数据包分配SN。例如:为所有经过所述第一协议层的数据包添加头部结构,并按照各个数据包的到达或者发送顺序进行SN顺序分配;为具有按序递交需求的数据包添加头部结构,并按照所述具有按序递交需求的数据包的到达或者发送顺序进行SN顺序分配;为需要动态路由的数据包添加头部结构,并按照所述需要动态路由的数据包的到达或者发送顺序进行SN顺序分配;基于RB粒度为数据包添加头部结构时,按照每个RB内的数据包的到达或者发送顺序进行SN顺序分配;基于QoS流粒度为数据包添加头部结构时,按照每个QoS流内的数据包的到达或者发送顺序进行SN顺序分配。
可选的,由于PDCP层也能够执行分配SN的操作,但是PDCP层只能进行自己单条路径传输的SN分配和重复检测/重排序,并不能处理两条路径的顺序,PDCP实体位于每条路径内部,不能处理其它路径数据。为了避免重复操作导致资源浪费,可以将所述第一协议层与PDCP层进行联合设计,在所述第一协议层分配SN的情况下,可以删除PDCP层的分配SN的操作。需要说明的是,对于所述第一协议层独立设计的情况,无需删除PDCP层的分配SN的操作,这样对当前的协议层影响较少,实现更便捷。
作为一个可选实施例,所述为数据包选择路由路径,包括以下一项:
(1)选择分流模式下的数据包的路由路径;
可选的,所述选择分流模式下的数据包的路由路径,包括:
根据第一信息选择分流模式下的数据包的路由路径;
所述第一信息包括以下至少一项:
网络负荷信息;
路径拥塞信息;
是否主路径或者优先路径;
传输质量信息;
路径配置比例信息;
数据缓存信息。
该实施例中,终端作为数据发送端时,可以在第一协议层对待发送的数据包进行分流(split)操作,选择合适的路由路径,进行后续的数据传输。例如:对于增加了头部结构的数据,它的路由选择可以相对动态,可以实时决定由路径1还是路径2传输,例如可以基于实时链路质量情况选择更优路径,或者基于网络负荷和拥塞情况选择更优路径,或者优先选择主路径或者优先路径,或者根据路径配置比例选择比例更高的路径,或者选择数据缓存较少的路径等。对于没有设置头部结构的数据,路径选择更加静态,尽量选择当前路径(即路径不变化),避免路径转换带来的接收乱序情况。需要说明的是,上述选择路径的方式仅为举例,终端可以基于自身需求或者配置并根据所述第一信息选择各个数据包的路由路径。
(2)确定所述数据包的复制操作的激活或者去激活状态,根据所述激活或者去激活状态,为所述数据包选择路由路径。
可选的,所述确定所述数据包的复制操作的激活或者去激活状态,包括:
根据第二信息确定所述数据包的复制操作的激活或者去激活状态;
其中,所述第二信息包括以下至少一项:
业务QoS信息;
网络负荷信息;
链路状态信息;
传输质量信息。
该实施例中,终端作为数据发送端时,可以在第一协议层对待发送的数据包进行复制(duplication)操作的激活或者去激活,选择合适的路由路径,进行后续的数据传输。例如:对于增加了头部结构的数据,它的复制操作的激活选择可以相对灵活,可以根据所述第二信息实时决定是否同时由路径1和路径2传输,例如基于业务QoS或者基于网络情况选择是否复制传输等,或者基于链路状态或传输质量选择是否复制传输。对于没有添加头部结构的数据包,则需要避免开启复制传输,尽量选择当前路径(即路径不变化),避免复制带来的接收重复情况。需要说明的是,上述确定数据包的复制操作激活或者去激活的方式仅为举例,终端可以基于自身需求或者配置并根据所述第二信息对各个数据包激活或者去激活复制操作。
作为一个可选实施例,所述方法还包括以下至少一项:
将QoS流映射到对应的RB;
将IP流映射到对应的QoS流。
该实施例中,QoS流到RB的映射操作和/或IP流到QoS流的映射操作也可以在所述第一协议层执行。由于当前的SDAP层也能够执行上述映射操作,在该实施例中将上述映射操作设置在第一协议层内执行,例如:终端作为数据发送端,在第一协议层增加的数据包头部结构中携带QoS flow ID和相应的NAS Reflective QoS比特,表明该QoS flow的上行也支持相同的IP流到QoS flow ID的映射关系,和或携带相应的AS reflective QoS比特,表明该QoS flow的上行也支持相同的QoS flow到RB的映射关系,这样在第一协议层完成SDAP的映射功能。对于数据接收端,可以根据接收的NAS reflective QoS比特和/或AS reflective QoS比特指示,按照下行相同的IP流到QoS flow的映射关系,处理上行映射,或者按照下行相同的QoS flow到RB的映射关系,处理上行映射。
可选的,由于当前的SDAP层能够执行QoS流到RB的映射操作、IP流到QoS流的映射,为了避免映射操作的重复执行导致资源浪费,可以将所述第一协议层与SDAP层进行联合设计,可以删除SDAP层的QoS流到RB的映射操作,和/或删除SDAP层的IP流到QoS流的映射操作。需要说明的是,对于所述第一协议层独立设计的情况,无需删除SDAP层数据映射操作,这样对当前的协议层影响较少,实现更便捷。
作为一个可选实施例,所述数据聚合相关处理包括以下至少一项:
读取数据包的头部结构,获取所述头部结构携带的信息;
对数据包进行重复检测;
对数据包进行重排序;
对数据包进行按序递交。
该实施例是针对所述终端作为数据接收端的情况,终端可以在第一协议层读取数据包的头部结构,获得头部结构携带的信息;可以基于读取的信息在第一协议层对数据包进行重复检测和/或重排序;对于重排序的数据包按需递交。
可选的,所述数据包的头部结构携带以下信息中的至少一项:
序列号SN;
数据包对应的QoS流标识;
RB标识;
QoS反向映射比特信息。
作为一个可选实施例,所述对数据包进行重复检测,包括:

可选的,所述根据所述数据包的头部结构携带的SN,识别重复数据,包括以下一项:
根据所述数据包的头部结构携带的SN和QoS流标识,确定QoS流标识相同且SN相同的数据包为重复数据;
根据所述数据包的头部结构携带的SN和RB标识,确定RB标识相同且SN相同的数据包为重复数据。
该实施例中,终端的第一协议层读取数据包的头部结构,获得数据包的SN、QoS流ID和/或RB ID。QoS流ID相同且SN相同的数据包认为是重复数据,和/或,RB ID相同且SN相同的数据包认为是重复数据,可以删除再次接收的重复数据。
作为一个可选实施例,所述对数据包进行重排序,包括:根据所述数据包的头部结构携带的SN对所述数据包进行重排序。
可选的,所述根据所述数据包的头部结构携带的SN对所述数据包进行重排序,包括:
基于第一粒度,并根据所述数据包的头部结构携带的SN对所述数据包进行重排序;
其中,所述第一粒度包括以下至少一项:
RB粒度;
QoS流粒度。
该实施例中,终端在第一协议层读取数据包的头部结构,获得数据包的SN、QoS流ID和/或RB ID,可以基于RB粒度或者QoS流粒度并结合数据包的SN对数据包进行重排序。例如:基于RB粒度:对于每个RB,基于该RB内的数据包的SN进行重排序;基于QoS流粒度:对于每个QoS流,基于该QoS流内的数据包的SN进行重排序。
作为一个可选实施例,所述对数据包进行重排序,包括以下至少一项:
在接收数据包的情况下,按照SN升序对接收的数据包进行排序,若发生接收缺口,则启动定时器;
在定时器启动的情况下,记录所述定时器的启动时刻之前接收的SN最大值或SN最大值加1;
在定时器超时前,对未满足按序递交的数据包进行缓存;
在定时器启动的情况下,若记录的SN最大值或者SN最大值加1之前的数据包全部按序递交,则停止所述定时器;
在停止所述定时器的情况下,若接收序列中再次发生接收缺口,则继续启动时器;
在定时器超时之后,若未全部接收到所述接收缺口中的数据包,则停止等待所述接收缺口中的数据包,并将其它数据包按照SN升序顺序向高层递交。
该实施例中,重排序可以采用重排序窗口(T-reordering)操作,对相同流ID或者RB ID的数据按照SN顺序进行排序,按序且连续接收的数据直接按照SN升序递交高层即可。对于出现的接收缺口(gap),启动T-reordering定时器,等待对应的时长,例如:接收到的数据包对应的SN为1、2、5,2和5之间出现gap;可以记录定时器启动前接收到的数据包的SN最大值或SN最大值加1,例如:记录5或者6;和/或,在等待定时器对应的时长的期间,接收到的数据包不满足按序递交,则对这部分数据包进行缓存,比如在等待期间接收到的数据包的SN为6、7,则缓存这部分数据包;和/或,在等待定时器对应的时长的期间,若记录的SN最大值或者SN最大值加1之前的数据包全部接收且按序递交,则可以停止定时器,例如:在等待期间接收到3、4,满足了按序递交,则可以停止定时器;和/或,在定时器停止后,若再次发现了gap,则继续启动定时器,例如:在按序递交完数据包7后,接收到数据包9,出现gap,则继续启动定时器,重复上述等待的步骤;在定时器超时后,若仍未全部接收到gap中的数据包,则停止等待未接收的数据包,将其它数据按序递交,例如:定时器超时后仍未接收到数据包8,则将其它的数据包如9、10等按照顺序递交高层。
作为一个可选实施例,所述方法还包括:
向网络侧设备发送能力信息;
其中,所述能力信息包括以下至少一项:
第五指示信息,用于指示所述终端支持独立设置的第一协议层,或者,支持与L2重构的第一协议侧层;
第六指示信息,用于指示所述终端支持的第一协议层的SN粒度信息;
第七指示信息,用于指示所述终端是否支持第一协议层或者分流服务。
该实施例中,终端可以向网络侧设备上报UE能力,可以作为单独的能力或者作为与多流功能绑定的能力进行上报。在所述能力信息中可以指示终端支持独立设置的第一协议层,或者支持与L2重构之后的协议层,所述能力信息中还可以指示终端支持的第一协议层的SN粒度信息等。网络侧设备需要详细知道UE支持该新的第一协议层功能的情况,才能进行后续配置和使用操作。
可选的,所述方法还包括:接收网络侧设备发送的第二配置信息,所述第二配置信息包括所述第一协议层的配置信息。
该实施例中,网络侧设备可以基于终端的能力配置第一协议层,例如:网络侧可以通过CP的配置过程,对重构的第一协议层以及相关层进行配置,由于既涉及核心网和UE之间的配置,也关联RAN和UE之间的配置,因此对于核心网与UE之间的配置使用NAS过程配置,对于RAN和UE之间的配置使用RRC过程配置。可选的,核心网节点和RAN节点需要对配置信息达成一致,核心网节点可以在向RAN节点发送的N2信令中携带新的信息,告知RAN节点配合进行所述第一协议层的配置。
可选的,所述第二配置信息还包括以下至少一项:
第八指示信息,用于指示删除SDAP层的QoS流到RB的映射操作;
第九指示信息,用于指示删除SDAP层的IP流到QoS流的映射操作;
第十指示信息,用于指示删除PDCP层的分配SN的操作;
第十一指示信息,用于指示修改PDCP层的安全操作输入参数。
该实施例中,对于所述第一协议层与L2层重构的情况,可以在第二配置信息中指示相关L2层删除重复的操作,例如:第一协议层执行QoS流到RB的映射操作和/或IP流到QoS流的映射操作,则可以删除SDAP层的QoS流到RB的映射操作和/或IP流到QoS流的映射操作;第一协议层执行分配SN的操作,则可以删除PDCP层的分配SN的操作,避免了重复操作造成的开销和资源浪费。
其中,所述第一协议层基于QoS flow进行SN分配时,其分配粒度与传统的PDCP分配SN的粒度有差别,此时可以修改PDCP层的操作,例如:PDCP层执行安全操作时,输入参数由RB ID+SN值改为QoS flow+SN值,这样PDCP层也可以直接使用DSLL的SN进行操作,且PDCP层不需要进行重排序功能,PDCP实体的重复检测功能较简单还可以继续进行,以应对RAN侧的重复传输。
作为一个可选实施例,所述方法还包括以下一项:
在所述第一协议层为数据接收端的情况下,向网络侧设备发送第三信息;
在所述第一协议层为数据发送端的情况下,接收网络侧设备发送的第三信息;

该实施例中,在所述终端是数据发送端的情况下,数据接收端可以向终端进行控制(control)PDU的发送,control PDU可以包括接收情况反馈,例如哪些数据包丢失,也可以包括链路情况反馈,例如链路质量变好/变差,也可以是请求数据发送端进行路径切换,或者请求数据发送端激活复制传输等。
在本申请实施例中,第一协议层独立设置和第一协议层与L2层重构的两种情况分别参见网络侧设备执行的方法实施例,在此不做赘述。
本申请的实施例,在终端和网络侧设备设置第一协议层,所述第一协议层位于空口接入技术协议层之上。所述第一协议层用于对数据进行数据分流相关处理和/或数据聚合相关处理,使得网络侧设备与终端在进行数据分流和接收时可以更灵活的操作,能够提升数据的传输效率和业务体验,在增强数据传输效果的基础上同时提升了系统效率。
