随着移动终端上的摄像头和传感器性能的不断提高,越来越多的终端可以收集对AI/ML模型训练必不可少的有价值的训练数据。对于许多AI/ML任务,移动终端收集的小样本数据对于训练全局模型具有重要的意义。
图2是本申请实施例提供的通信系统200的示例。所述通信系统200也可称为联邦学习架构。
如图2所示,联邦学习服务器201通过聚合各个终端202上报的局部训练结果来完成全局模型的训练。在每次训练迭代中,终端202可以使用本地的训练数据,对从联邦学习服务器201下载的全局模型执行训练,然后通过5G上行信道向联邦学习服务器201上报中间训练结果(例如DNN的梯度)。然后联邦学习服务器201对收集的梯度进行聚合,并更新全局模型。联邦学习服务器201通过5G下行信道将更新后的全局模型分发给终端202,终端2020针对这一更新模型进行下一次的迭代训练。
联邦学习服务器201或终端200进行迭代训练中使用的参数包括但不限于批次大小(batch size),批次大小用于定义一次训练所选取的样本数,或批次大小用于定义训练的每次迭代处理所选取的样本数。批次大小的取值影响模型的优化程度和速度,也直接影响到处理器内存的使用情况。可选的,处理器内存越小,批次大小的取值越小。不同批次大小所需传输时延和传输速率不同,下面结合表1进行说明。
表1
Figure PCTCN2021070968-appb-000001
如表1所示,批次大小越大,则处理器处理时间以及必要的时延越长,需要的数据速率越小。具体而言,一次的迭代过程中,联邦学习服务器201下发模型数据的传输速率为6.5-20.3Gbps,同理,一组终端202向联邦学习服务器201上传训练结果的传输速率为6.5-20.3Gbps。一组终端202和网络之间均需要高质量的通信来保证数据的交换,从而保证数据集的多样性和模型的泛化性,而不是仅仅只保证其中的一个或几个终端202的传输质量。
一组终端202和网络之间可以通过网络切片来保证数据的交换。即数据是绑定在相应的QoS流上进行传输的。网络切片可以使用单一网络切片选择辅助信息(Single-Network Slice Selection Assistance Information,S-NSSAI)来标识。S-NSSAI的集合成为NSSAI。结合图1来说,UE 101需要使用网络切片时需要先向AMF实体103请求切片使用,AMF实体103同意后,UE 101再请求在切片中建立PDU会话来传输数据。UE 101根据业务,把要请求的S-NSSAI放在请求NSSAI(Requested NSSAI),请求NSSAI被包含在注册请求(Registration request)中发送给AMF实体103。AMF实体103根据UE 101的签约和网络切片部署的范围确定允许NSSAI(Allowed NSSAI),允许NSSAI放在注册接受(Registration accept)消息中发给UE 101,也放在N2消息中发给AN设备102。UE 101在收到允许NSSAI后,需要在允许NSSAI中的切片中选择业务对应的切片中建立协议数据单元(Protocol Data Unit,PDU)会话。PDU会话建立完成后才可以收发数据。
应理解,图2所示的场景仅为本申请的方案可适用的场景的示例,不应理解为对本申请的限制。换言之,本申请提供的方案可适用于任一种需要同时保证一组节点的通信质量的应用场景。
图3是本申请实施例提供的QoS流在用户面的端到端OoS控制与映射关系的示意图。
如图3所示,PCF根据从各个网元收集的信息和自身的配置,制定策略计费控制(Policy Charging Control,PCC)规则(PCC rule),并将PCC规则发送给SMF,SMF基于此分别向UPF、AN、UE提供以下三种信息,实现端到端的服务质量(Quality of service,QoS)控制:SMF提供给AN的QoS策略(QoS profile)。其中,QoS策略可包括这个QoS流的以下QoS参数:5G服务质量标识(5G QoS Identifier,5QI),分配与保持优先级(Allocation and Retention Priority,ARP)以及码率要求等信息。SMF提供给UE的一个或多个QoS规则(QoS rule),主要用于上行数据的检测。SMF提供给UPF的一个或多个上下行报文检测规则(Packet Detection Rule,PDR)以及对应的QoS执行规则。
在下行方向,UPF将收到的数据包根据SMF发送的PDR中的下行包过滤器集的优先级从高到低进行匹配。如果找到下行匹配的PDR,根据匹配结果将对应的QFI封装到报头。RAN根据QFI将数据包映射到对应的DRB。如果没有匹配到下行PDR,UPF丢弃该数据包。在上行方向,UE将需要发送的数据包根据QoS规则(QoS rule)中的上行包过滤器集的优先级从高到低匹配。如果匹配上,则UE使用对应QoS规则中的QFI将上行报文绑定到QoS流,进一步将QoS流绑定对应的数据无线承载(Data Radio Bearer,DRB)。如果没有匹配上,则UE丢弃该数据包。但是,在UE中存在默认的QoS规则,其设置的包过滤器可以允许所有的数据包,目的在于可以匹配所有的数据包,防止上行数据包的丢失。
作为通信质量的重要衡量标准,通常使用QoS参数表示QoS流的特征。QoS流主要分为最低保障速率(Guaranteed Bit Rate,最低保障速率)QoS流和非GBR QoS(non-GBR QoS)流,对于GBR QoS流,网络需要预留资源保证带宽。
QoS参数主要有5QI、ARP、RQA、保证流速率(Guaranteed Flow Bit Rate,GFBR)、最大流比特率(Maximum Flow Bit Rate,MFBR)、通知控制、聚合最大速率(Aggregate Maximum Bit Rate,AMBR)等。下面对各个参数进行说明。
5QI可以理解为指向多种QoS特征值的一个标量,分为标准化5QI、预配置5QI、动态分配5QI三种。对于动态分配的5QI,核心网在向基站提供QoS流的QoS流配置时候,不但要在QoS流配置中包括5QI,还要包括这个5QI对应的完整的QoS特征值的集合。对于标准化和预配置的5QI,核心网只需要提供5QI,基站就可以解析出这个5QI对应的多种QoS特征值的集合。另外,对于一个标准化或预配置的5QI,也允许核心网提供与标准化或者预配置所不同的一个或者多个QoS特征值,用于修改相应的标准化或者预配置的QoS特征值。标准化5QI主要用于比较通用的,使用频率高的业务,。动态分配的5QI主要用于标准化5QI无法满足的不太通用的业务。
ARP分配与保持优先级,具体包括优先级别、资源抢占能力、是否允许资源被抢占三类信息,用于在资源受限时候确定是否允许QoS流的建立、修改、切换,一般用于GBR类型的QoS流的接纳控制。ARP也用于在资源受限时候抢占现有的QoS流的资源,比如高优先级的QoS流可以抢占低优先级的QoS流。
RQA指示某些SDF承载的QoS流应用反向映射QoS。
GFBR指示基站在平均时间窗内保证预留足够的资源为一个QoS流传输的码率。MFBR限制为QoS流传输的最大码率。
QoS通知控制指示当基站无法保证QoS流的GFBR时,继续努力保持QoS流并通知核心网QoS需求无法保证,NG-RAN尝试重新保证,并通知SMF,QoS需求重新保证。
会话AMBR(Session-AMBR)控制的是一个PDU会话的所有的non-GBR类型的QoS流的总码率。UE-AMBR控制的是一个UE的所有non-GBR类型的QoS流的总码率。
图4是本申请实施例提供的会话建立过程300的示意性流程图。
如图4所示,所述会话建立过程300可包括:
S301,UE向AMF发送会话建立请求消息,包含会话标识,会话类型(初始建立会话、EPS到5GS切换、Non-3GPP到3GPP切换、请求紧急业务),SCC mode、DNN、S-NSSAI等参数。
S302,AMF根据DNN、S-NSSAI和签约数据选择合适的SMF。
S303,AMF调用选择的SMF的会话服务触发会话建立。
S304,SMF从UDM获取会话签约数据,例如用户允许的SCC模式(mode),会话类型以及会话的Session-AMBR。
S305,SMF为该会话选择PCF。
S306,SMF与PCF建立策略连接,获取PCC规则。
S307,SMF建立UE、AN、UPF之间的用户面连接。主要是CN tunnel info分配,AN tunnel info获取。SMF通过AMF和AN向UE发送会话建立接受消息。
S308,SMF向UDM注册,UDM记录此对话对应的SMF ID。
S309,SMF为UE分配IPv6前缀,通过用户面发送给UE。
可以发现,在图4所示的会话建立过程300中,QoS流是针对单个UE的,即网络可以为每个UE分配资源保证其传输质量。但是,当遇到上述所说的联邦学习的场景,网络需要保证一组节点整体的传输质量,而不仅仅是单个节点的质量。会话建立流程300中涉及参数,无法指示网络实现对一组节点服务质量的保证,也无法根据组内不同节点之间的通信质量以及计算能力的差异性,实现灵活的跨UE资源调度,保证一组节点高效的完成一次训练的迭代。
UE进行AI模型参数的传输,需要极高的传输速率,因此,为实现网络对一组节点服务质量的保证,同时根据组内不同节点之间的通信质量以及计算能力的差异性,实现灵活的跨UE资源调度,保证一组节点高效的完成一次训练的迭代,本申请引入新参数,即组-GBR/MBR(Group-GBR/MBR)。Group-GBR表示一组正在进行相同任务的节点,网络为其保证的传输速率,即组内所有节点进行同一任务的所有QoS流的GBR的和。Group-MBR表示一组正在进行相同任务的节点,网络限制其传输的最大速率,即组内所有节点进行同一任务的所有QoS流的GBR的和/或组内所有节点进行同一任务的所有QoS流的non-GBR的和。

下面结合具体实施例对本申请的方案进行说明。
实施例1:
本实施例中,在同一个网络切片和/或同一个AI模型采用相同SMF情况下,基于组-GBR/MBR的会话建立流程。假设节点组,即一组UE,采用相同的网络切片或者同一个AI模型进行模型训练参数的传输和全局模型的下载,网络将与联邦学习相关的策略与UE正在进行的其他业务的通信策略相区分。因此,网络可以调节每个UE的QoS策略而不影响其他非联邦学习的数据传输。
图13是本申请实施例提供的会话建立过程500的示意性框图。所述方法500可以由UE、AN、AMF、UPF、SMF、PCF以及UDM交互执行。例如图1所示的相应的实体或网元。
如图13所示,所述会话建立过程500可包括以下中的部分或全部内容:
S501,UE向AMF发送会话建立请求消息,包含S-NSSAI、深度神经网络(Deep Neural Networks,DNN)或某个人工智能(artificial intelligence,AI)模型标识。

S503,AMF调用选择的SMF的会话服务触发会话建立。

S505,SMF为该会话选择PCF。
S506,SMF向PCF发送会话建立/更新请求,包含签约的组-GBR/MBR。
S507a,PCF根据FL服务器提供的联邦节点数量以及SMF提供的组-GBR/MBR,确定作为联邦节点的UE建立此会话的业务流级别的GBR和MBR,SCF基于GBR和MBR制定UE相应QoS流的GFBR和MFBR。
S507b,因为所有的UE受同一个SMF管理,因此,SMF自身可以根据组-GBR/MBR制定UE相应QoS流的GFBR和MFBR。
需要说明的是,S507a和S507b作为制定UE相应QoS流的GFBR和MFBR的两种实现方式,在实际中,可以选择其中一种方式实现本实施例的方案。
S508,SMF向UPF发送N4会话建立修改请求,并分配核心网的隧道信息(CN tunnel info)。
S509,SMF向AMF提供基于组-GBR/MBR制定的GFBR和MFBR,通过AMF将GFBR和MFBR发送给RAN。
S510,N2消息中包含GFBR和MFBR发给基站。
S511,RAN根据收到的QoS参数,执行相应的空口资源建立。
本实施例中,通过获得签约的组-GBR/MBR,SMF和/或PCF制定相应的一组UE的QoS参数,实现网络对一组节点服务质量的保证。
实施例2:
本实施例中,同一个网络切片和/或同一个AI模型采用相同PCF情况下,基于组-GBR/MBR的会话建立流程。即当一节点组内的节点进行联邦学习时,可以为不同UE选择不同的SMF建立基于同一个网络切片或者同一个AI模型的会话,但是这些SMF需要选择相同的PCF,来制定基于一组节点的统一的会话策略。
图14是本申请实施例提供的会话建立过程600的示意性框图。所述方法600可以由UE、AN、AMF、UPF、SMF、PCF以及UDM交互执行。例如图1所示的相应的实体或网元。
如图14所示,所述会话建立过程600可包括以下中的部分或全部内容:
S601,UE向AMF发送会话建立请求消息,包含S-NSSAI、DNN或某个AI模型标识。
S602,SMF从UDM获得签约数据,指示需要为该S-NSSAI和DNN或执行该AI模型训练的UE选择SMF,但一组节点不必选择相同的SMF。
S603,AMF调用选择的SMF的会话服务触发会话建立。
S604.SMF从UDM获取会话签约数据,若该会话为联邦节点进行联邦学习的会话,则SMF从UDM获取签约的组-GBR/MBR。
S605,SMF为该会话选择PCF,一组联邦节点进行联邦学习需要选择相同的PCF。
S606,SMF向PCF发送会话建立/更新请求,包含签约的组-GBR/MBR。
S607,PCF根据FL服务器提供的联邦节点数量以及SMF提供的组-GBR/MBR,确定作为联邦节点的UE建立此会话的业务流级别的GBR和MBR,SMF基于GBR和MBR制定UE相应QoS流的GFBR和MFBR。

本实施例中,通过获得签约的组-GBR/MBR,SMF和/或PCF制定相应的一组UE的QoS参数,实现网络对一组节点服务质量的保证。
实施例3:
本实施例中,核心网侧实现基于组-GBR/MBR的联邦节点间资源共享。不同的联邦节点之间,因其计算能力的差异,导致每个节点完成训练并进行结果传输的时间各不相同,因此,仅根据会话建立流程中制定的GFBR和MFBR,无法保证一组节点高效的信息传输。因此,为了最大化的应用组-GBR/MBR,保证一组节点整体的性能,而不是单个节点的性能,需要各个节点之间的空口资源可以灵活共享,实现高效的迭代训练。
图15是本申请实施例提供的无线通信方法700的示意性框图。所述方法700可以由UE、基站、核心网控制面网元、核心网用户面网元以及AI服务器交互执行,例如核心网控制面网元也可以是策略控制网元、核心网用户面网元可以是用户面功能网元,AI服务器可以是具有学习能力或数据处理能力的服务器。
如图15所示,所述方法700可包括以下中的部分或全部内容:
S701,引入第一指示信息,AI服务器将收到的一组联邦节点上传训练结果数据的时间指示给核 心网的控制面网元。
S702,核心网的网元根据第一指示信息,触发会话修改流程。
S703,在组-GBR/MBR一定的情况下,根据第一指示信息,修改相应UE相应会话的QoS参数。例如,对于较早传输数据的UE,减小GFBR和MFBR的值,对于较慢传输数据的UE,增加GFBR和MFBR的值。
S704,核心网控制面将新的QoS参数值发给核心网用户面网元。
S705,核心网控制面将新的QoS参数值发给基站,指示基站进行组内节点空口资源的调度。
S706,核心网控制面将新的QoS参数值发给UE,用于UE上行数据的传输。
本实施例中,通过引入第一指示信息,实现核心网侧在组-GBR/MBR不变的情况下,灵活分配不同UE的空口资源,消除因UE之间计算能力的差异性导致的一组节点数据传输完成时间的差异性,实现一组节点高效完成一次训练的迭代。
实施例4:
本实施例中,基站侧实现基于组-GBR/MBR的联邦节点间资源共享。当一组联邦节点均通过同一个基站接入,进行联邦学习数据的传输时,基站侧可以根据接收到不同节点上传数据的时间,在保证整体组-GBR/MBR不变的情况下,灵活调整各节点间的空口资源,提高计算能力低的UE对应的数据传输速率,降低计算能力强的UE对应的数据传输速率。
图15是本申请实施例提供的无线通信方法800的示意性框图。所述方法800可以由UE、基站、核心网控制面网元、核心网用户面网元以及AI服务器交互执行,例如核心网控制面网元也可以是策略控制网元、核心网用户面网元可以是用户面功能网元,AI服务器可以是具有学习能力或数据处理能力的服务器。
如图15所示,所述方法800可包括以下中的部分或全部内容:
S801,基站从核心网网元得到一组节点的组-GBR/MBR参数。
S802,基站可以根据收到从不同节点传输数据的时间,在保证组-GBR/MBR一定的基础上,对每个节点的QoS参数进行调整。例如,对于较早传输数据的UE,减小GFBR和MFBR的值,对于较慢传输数据的UE,增加GFBR和MFBR的值。
S803,基站触发会话修改流程。
S804-S806可参见实施例三中的S704-S706,为避免重复,此处不再赘述。
本实施例中,基站通过获得组-GBR/MBR,在组-GBR/MBR不变的情况下,实现一组UE QoS参数的灵活修改,消除因UE之间计算能力的差异性导致的一组节点数据传输完成时间的差异性,实现一组节点高效完成一次训练的迭代。
综上所述,本申请实施例提供的方案,能够实现网络对一组节点服务质量的保证,同时根据组内不同节点之间的通信质量差异性,实现灵活的跨UE资源调度,保证一组节点高效的完成一次联邦学习训练的迭代。
