下面对本申请所涉及的技术点进行简单说明。
1、5G网络数据分析服务
网络数据分析功能(Network Data Analytics Function,NWDAF)是5G核心网控制面(5GC)网络功能之一,根据不同目的可以与不同的实体进行交互,如:
1)基于AMF、SMF、PCF、UDM、AF(直接或通过NEF)或操作管理维护(Operation Administration Maintenance,OAM)提供的事件订阅来收集数据;
2)[可选]使用数据收集协调功能(Data Collection Coordination Function,DCCF)进行分析和数据收集;
3)从数据存储库检索信息(例如通过UDM检索用户相关信息的UDR);
4)[可选]从分析数据存储功能(Analytics Data Repository Function,ADRF)存储和检索信息;
5)从消息框架适配功能(Messaging Framework Adaptor Function,MFAF)分析和数据收集;
6)检索有关网络功能(Network Function,NFs)的信息(例如,从NRF检索与NFs相关的信息);
7)根据需求向消费者提供分析;
8)向消费者提供大量数据。
请参考图2和图3,图2为使用DCCF的数据采集体系构架的示意图,图3为使用DCCF的网络数据分析开放体系结构的示意图。
在某些情况下,数据消费者(如NWDAF或ADRF)直接从数据源网络功能(Network Function,NF)收集数据,例如,当NWDAF与5GC NF共部署时,为了使数据消费者能够直接获得由NWDAF或ADRF收集的数据(即不通过DCCF),NWDAF或ADRF可以在数据收集过程中或之后向DCCF注册/更新数据收集摘要/配置文件(data collection profile)。然后,DCCF可以确定所请求的数据在NWDAF或ARDF中是可用的,并可以根据数据收集摘要/配置文件(data collection profile)协调数据收集。请参考图4,过程简述如下:
步骤1:一个ADRF或NWDAF实例正在或已经直接收集数据,例如从相同位置共部署的NF收集。
步骤2:ADRF或NWDAF通过调用Ndccf_ContextManagement_Register或Ndccf_ContextManagement_Update向DCCF请求注册/更新数据收集摘要/配置文件(可以包括:服务操作、分析/数据规范、ADRFID或NWDAF ID)。注册/更新请求可以由数据源(如相同位置共部署的NF)触发,它可以在数据采集开始之前或在数据采集完成之后。DCCF根据分析/数据规范确定NWDAF或ADRF的数据收集状态,例如DCCF确定所需数据是否正在收集或已经收集。其中,“服务操作”是指用于从数据源收集数据或分析的服务(例如:Namf_EventExposure_Subscribe或Nnwdaf_AnalyticsSubscription_Subscribe)。“分析/数据规范”是用于识别所收集数据的“服务操作”特定参数(即:分析ID(s)/事件ID(s),分析报告的目标或事件报告的目标,分析过滤器或事件过滤器,等等)。NWDAF ID或ADRF ID指定注册数据收集摘要/配置文件的ADRF或NWDAF。
步骤3:DCCF用Ndccf_ContextManagement_Register Response或Ndccf_ContextManagement_Update Response对ADRF或NWDAF进行响应。
步骤4:如果数据消费者被配置为通过DCCF使用Ndccf_DataManagement_Subscribe服务操作来收集数据,那么可根据相应地流程通过DCCF收集所需即时收集数据或历史数据。
步骤5:ADRF或NWDAF通过调用Ndccf_ContextManagement_Deregister向DCCF请求删除数据收集或分析收集的注册。
2、数据面
目前6G网络架构讨论中,业界多家公司提出了数据面。数据面由核心网数据面功能、无线接入网数据面功能和用户设备(User Equipment,UE)数据面功能组成,具备端到端的连通性,用户设备也称为终端。数据面负责数据控制,包括数据收集协调、数据收集配置和数据传输配置等。数据面还负责数据采集、数据传输、数据预处理、数据隐私安全、数据分析、数据存储和数据服务等功能。数据面示意图如图5所示。
对于数据收集,相关方案中存在如下问题:
1)相关协议标准主要考虑了核心网内NWDAF和ADRF将所收集的数据注册到DCCF,以便于DCCF根据数据需求确定是否该数据正在或已经被NWDAF/ADRF收集。未来数据收集和分享普遍存在时,UE和无线接入网的数据也是数据收集和分享的重要组成部分,因此需支持UE和无线接入网数据收集和复用。
2)现有数据收集摘要/配置文件(data collection profile)方案数据收集节点与data collection profile注册节点必须为同一节点,未来可能出现二者不同的情况。
3)现有data collection profile包括服务操作和服务操作的特定参数,在跨域(无线接入网(Radio Access Network,RAN)和核心网(Core Network,CN))数据共享中应避免RAN内部或CN内部信息不必要的信息暴露,因此在跨域数据共享时应该支持RAN域数 据控制功能作为其它RAN功能的代理,提供数据或数据的描述信息。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的数据收集方法、数据收集装置、通信设备及存储介质进行详细地说明。
请参考图6,本申请实施例提供一种数据收集方法,包括:
步骤61:第一功能节点在接收到第一数据请求之后,根据所获得的数据摘要确定所述第一数据请求所请求的第一数据的收集状态信息,所述数据摘要用于描述数据提供功能节点正在收集或者已经收集的数据的信息;
步骤62:所述第一功能节点根据所述第一数据的收集状态信息,确定用于提供所述第一数据的数据提供功能节点或数据存储功能节点,所述数据存储功能节点用于存储所述数据提供功能节点收集的数据。
在本申请实施例中,通过数据摘要的方式,数据提供功能节点在进行数据注册时,不需要将正在收集或者已经收集的数据本身传输给第一功能节点,只需要传输数据摘要即可,减少了需传输的数据量,同时,也实现了一定程度上的不同域的数据隔离,提高了数据安全性。由第一功能节点统一获取数据摘要信息,提供了对数据消费功能节点更加友好的数据服务,避免数据消费功能节点维护所需数据与数据控制功能之间的映射关系。
本申请实施例中,可选的,所述第一功能节点用于执行数据收集协调(Data Collection Coordination)。
本申请实施例中,可选的,所述第一数据请求由数据消费功能节点发送。
本申请实施例中,可选的,所述数据提供功能节点可以包括以下至少一项:第一功能节点和第二功能节点,所述第二功能节点为用于进行数据收集或存储的节点。若第一功能节点作为数据提供功能节点进行数据收集,第一功能节点可以生成自身正在收集或已经收集的数据的数据摘要并存储。若第二功能节点作为数据提供功能节点进行数据收集,第二功能节点可以生成自身正在收集或已经收集的数据的数据摘要,并发送给第一功能节点。或者,还存在于一些情况,第二功能节点自身的存储能力有限,可以将收集的数据存在到第三功能节点(即数据存储功能节点),此时,也可以由第三功能节点生成第二功能节点正在收集或已经收集的数据的数据摘要,并发送给第一功能节点。也就是说,上述第一功能节点“所获得的数据摘要”可以包括以下至少一项:第一功能节点生成的数据摘要,第二功能节点生成的数据摘要,第三功能节点生成的数据摘要。
也就是说,本申请实施例中,数据摘要的数据收集节点与数据摘要注册节点可以是不同节点,也可以是同一节点。
本实施例中,面向存储能力受限的UE,或者数据收集和数据存储解耦的网络架构,既支持数据摘要注册节点与数据提供节点不同的情况,也支持数据提供节点代理数据收集节点注册数据摘要。本申请实施例扩展支持了数据收集节点和数据摘要注册节点不同的情况,避免了跨域数据共享时不必要的域内信息共享,既提供了数据安全性,也简化了跨域数据共享。
本申请实施例中,可选的,所述第一功能节点可以是核心网网络功能,如数据控制功能(Data Collection Function,DCF)等,所述第一功能节点也可以是无线接入网网络功能,如无线接入网数据控制功能(RAN-DCF)等。
本申请实施例中,可选的,所述第二功能节点可以是核心网网络功能,如AMF,SMF,NWDAF或ADRF等,所述第二功能节点也可以是无线接入网网络功能,如基站(gNB),无线接入网数据控制功能(RAN-DCF),或RAN能力开放功能(RAN exposure function)、集中单元控制面(CU-CP),集中单元用户面(CU-UP),或,分布式单元(Distributed Unit,DU)等。其中,与LTE或NR协议中核心网网络功能服务能力开放功能(Service Capability Exposure Function,SCEF)和NEF)相对应,RAN exposure function通过应用程序接口(Application Programming Interface,API)等接口方式开放3GPP无线接入网网络能力。所述第二功能节点也可以是终端(UE)。
在一些实施例中,可选的,第一功能节点和第二功能节点可以同属核心网网络功能,例如,第一功能节点为DCF,第二功能节点为AMF、SMF、NWDAF、ADRF等。
在一些实施例中,第一功能节点和第二功能节点可以同属无线接入网网络功能,例如,第一功能节点为无线接入网数据控制功能(RAN-DCF),第二功能节点为CU-CP,CU-UP或DU等。
在一些实施例中,第一功能节点是核心网网络功能,第二功能节点为无线接入网网络功能。
在一些实施例中,第一功能节点是核心网网络功能,第二功能节点为终端。
在一些实施例中,第一功能节点是无线接入网网络功能,第二功能节点为终端。
也就是说,本申请实施例中,扩展了数据收集的场景,并非仅考虑核心网内NWDAF和ADRF将所收集的数据注册到DCCF,也支持UE和无线接入网的数据收集。
本申请实施例中,可选的,所述第一数据的收集状态信息包括以下之一:所述第一数据正在收集或者已经收集;所述第一数据的第一部分数据正在数据或者已经收集;所述第一数据未被收集。
本申请实施例中,可选的,所述第一功能节点根据所述第一数据的收集状态信息,确定用于提供所述第一数据的数据提供功能节点或数据存储功能节点可以包括以下之一:
若根据所获得的数据摘要确定所述第一数据的收集状态信息为:所述第一功能节点正在收集或已经收集第一数据,此时,所述第一功能节点确定自身为第一数据的数据提供功能节点;
若根据所获得的数据摘要确定所述第一数据的收集状态信息为:所述第一功能节点正在收集或已经收集第一数据的部分数据,此时,所述第一功能节点确定自身为第一数据的数据提供功能节点。
若根据所获得的数据摘要确定所述第一数据的收集状态信息为:所述第二功能节点正在收集或已经收集第一数据,此时,所述第一功能节点确定第二功能节点或第三功能节点 为第一数据的数据提供功能节点。
若根据所获得的数据摘要确定所述第一数据的收集状态信息为:所述第二功能节点正在收集或已经收集第一数据的部分数据,此时,所述第一功能节点确定第二功能节点或第三功能节点为第一数据的数据提供功能节点。
若根据所获得的数据摘要确定所述第一数据的收集状态信息为:所述第一数据未被收集,此时,所述第一功能节点确定可生成所述第一数据的节点为所述第一数据的数据提供功能节点。
本申请实施例中,可选的,所述数据摘要也可以称为数据收集摘要/配置文件(data collection profile),或者,也可以称为元数据(meta data),所述数据摘要是用于定义或解释收集数据的数据信息。
本申请实施例中,可选的,所述数据摘要包括以下至少一项:
1)数据摘要标识,用于在所述第一功能节点的控制范围内唯一标识所述数据摘要和所述数据摘要对应的数据;
2)数据项,用于指示数据信息,所述数据信息包括以下至少一项:数据名称,数据标识符,数据集名称,数据集标识符;
所述数据名称例如可以是:参考信号接收功率(Reference Signal Received Power,RSRP)、参考信号接收质量(Reference Signal Received Quality,RSRQ)、体验质量(Quality of Experience,QoE),分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)延迟(delay)等。
所述数据标识符例如是:identifier 1,identifier 2,identifier 3,分别表示不同的数据。
所述数据集名称例如是:感知数据集,感知数据集包括时延、角度、多普勒和信号强度等。AI模型数据集,AI模型数据集包括面向不同场景(如不大于3km/h的低速用户,或大于120km/h的高速用户)适用的模型等。
所述数据集标识符例如是:identifier 1,identifier 2,identifier 3,分别表示不同的数据集。
3)数据收集控制功能节点标识,用于标识数据收集控制功能节点,所述数据收集控制功能节点用于控制数据提供功能节点进行数据收集;
本申请实施例中,可选的,数据收集控制功能节点标识包括以下至少一项:数据收集控制功能节点ID,数据收集控制功能节点IP地址,数据收集控制功能节点端口号。
本申请实施例中,如果第二功能节点是gNB或类似的无线接入网网络功能节点等,数据收集控制功能节点通常为基站,数据收集控制功能节点标识可以为gNB ID或6G无线接入网节点标识或者是无线接入网数据控制功能(RAN-DCF)ID;如果第二功能节点为核心网网络功能,数据收集控制功能节点可以是第一功能节点,数据收集控制功能节点标识可以为第一功能节点标识。
本申请实施例中,可选的,第一功能节点可以根据数据收集控制功能节点标识对正在 进行的数据收集进行修改更新以满足数据需求。
4)数据提供功能节点标识;
本申请实施例中,可选的,第一功能节点可以根据数据提供功能节点标识获取对应的数据,或者,第一功能节点可以根据数据提供功能节点标识配置第一功能节点向数据消费功能节点提供所需的第一数据。
本申请实施例中,假设数据提供功能节点无线接入网网络功能,如果无线接入网不希望暴露RAN内部信息,那么数据提供功能节点标识可以统一为gNB ID或6G无线接入网节点标识或RAN exposure function ID等。即使数据可能是RAN-DCF收集的数据,也可能是CU-CP配置的测量数据,也可能是gNB等对上行数据进行测量得到的数据,也可能是UE上报给无线接入网络功能节点的数据,也可能是无线接入网功能节点对UE上报数据进行处理后的数据,但是通过前所统一的标识可避免暴露RAN内部的信息。如果核心网需要知道真实的数据提供功能节点,那么数据提供功能节点则需要根据数据提供功能节点而具体设置为RAN-DCF、CU-CP、gNB等。需要指出的是,数据提供功能节点也可以与数据摘要提供功能不同,例如数据提供功能节点为UE A,数据摘要的提供功能为gNB x;或者数据提供功能节点为CU-CP y,数据摘要提供功能为RAN-DCF z。
5)数据存储功能节点标识;

9)数据收集标识,用于在数据提供功能节点的控制范围内唯一标识以下至少两项之间的关联关系:数据项,数据收集控制功能节点标识,数据提供功能节点标识,数据生成时间,数据生成地点,数据对应的测量对象;
10)数据类型;

11)数据状态,用于指示数据所处的数据生命周期的信息;
一种简化的数据生命周期定义方法是:包括生成期和使用期,生成期是指数据正在产 生和收集中,使用期是指数据可以被各数据消费功能节点使用,数据可以处于生成期或使用期,也可以同时处于生成期和使用期。
另一种数据生命周期定义方法是:包括生成期、活动期、衰退期、归档期和销毁期。其中,活动期、衰退期和归档期均是按照数据被访问的频率来进行定义的,例如访问频率高于第一阈值为活动(活跃)期;低于第二阈值并且高于第三阈值则为衰退期,进入衰退期后,数据活动日益减少,如果出现剧烈活动可能是非预期的,往往预示着数据价值的再发现或者数据安全性事件的发生;低于第三阈值则为归档期,此时数据的访问进入非常稀疏的阶段,并且数据不再更新。当数据已经没有使用上的价值或者已经超越了法规监管的周期,这个时候数据需要被销毁则称为销毁期。
另一种数据生命周期的定义方法是:数据隐私和安全、数据生成和收集、数据存储、数据传输、数据处理、数据消费和数据质量管理等。根据数据处理的各个阶段进行划分定义的,例如数据正在生成和收集,那么数据收集控制功能节点可以通过修改现有的数据收集来提供第一数据;如果数据处于数据存储,那么数据收集控制功能节点可以通过数据存储功能节点来提供第一数据。
12)数据有效期。
用于指示数据在多长时间内有效,可以是绝对时间,例如某年某月某日前有效等,或相对时间,例如数据生成后1年有效等。数据有效期可根据数据价值、数据提供者意愿、法规监管的周期等进行设置,可以由数据提供者根据意愿指示数据可被使用的有效期,也可以由数据收集者根据存储空间大小和/或数据访问情况确定有效期。

下面结合具体应用场景对本申请实施例的数据收集方法举例进行说明。
实施例1:
本实施例中,第一功能节点为核心网网络功能,第二功能节点为无线接入网网络功能,由第一功能节点控制第二功能节点进行数据收集,即数据提供功能节点为第二功能节点。
本实施例中,假设第一功能节点是核心网网络功能,如核心网数据控制功能(CN-DCF),第二功能节点是无线接入网网络功能,如基站(gNB),无线接入网数据控制功能(RAN-DCF),或RAN能力开放功能(RAN exposure function)等。这就意味着所有数据消费功能节点均向核心网的第一功能节点进行请求,然后由核心网的第一功能节点进行数据协同。由核心网的第一功能节点进行数据协同的好处是可以在较大范围内进行数据协同,并且数据消费功能节点不需要根据数据或地理位置范围等向不同的第一功能节点进行请求,数据服务对数据消费功能节点更加友好。通过发送数据摘要的方式,大部分情况第二功能节点无需发送数据本身,也可以实现一定程度上的数据隔离和减少数据传输量。
本申请实施例的数据收集方法包括以下步骤:
步骤1:可选的,第一功能节点向第二功能节点发送数据摘要配置信息,所述数据摘要配置信息包括数据摘要的更新周期和触发数据摘要更新的事件配置信息中的至少一项。所述触发数据摘要更新的事件配置信息例如为出现某一数据生成地点时发送数据摘要,或者,出现某一数据提供功能节点的数据时发送数据摘要。
在本申请的其他一些实施例中,第二功能节点也可以根据网络管理功能的配置信息,获取所述第一功能节点的标识和所述数据摘要配置信息。
步骤2:第二功能节点根据数据摘要配置信息向第一功能节点发送数据摘要注册或数据摘要更新。所述数据摘要注册或数据摘要更新中包括数据摘要。
其中,数据摘要包括以下至少一项:
数据摘要标识,例如M。
数据项,例如RSRP、RSRQ、PDCP delay。
数据收集控制功能节点标识,本实施例中,以第二功能节点是gNB或类似的无线接入网网络功能节点为例,那么数据收集控制功能节点通常为基站,数据收集控制功能节点标识可以为gNB ID或6G无线接入网节点标识或者是无线接入网数据控制功能(RAN-DCF)ID;如果第二功能节点为核心网网络功能,数据收集控制功能节点可以是第一功能节点,数据收集控制功能节点标识可以为第一功能节点标识。
数据提供功能节点标识,如果无线接入网不希望暴露RAN内部信息,那么数据提供功能节点标识可以统一为gNB ID或6G无线接入网节点标识或RAN exposure function ID等,即使数据可能是RAN-DCF收集的数据,也可能是CU-CP配置的测量数据,也可能是gNB等对上行数据进行测量得到的数据,也可能是UE上报给无线接入网络功能节点的数据,也可能是无线接入网功能节点对UE上报数据进行处理后的数据。如果核心网需要知道真实的数据提供功能节点,那么数据提供功能节点也可以与数据摘要提供功能不同,例如数据提供功能节点为UE A,数据摘要的提供功能为gNB x;或者数据提供功能节点为CU-CP  y,数据摘要提供功能为RAN-DCF z。
数据生成时间,用于指示数据生成的时间。
数据生成地点,如果是第二功能节点测量上行信号产生的数据,因为基站位置通常固定,所以可以不包括数据生成地点或仅提供一次该信息。
数据对应的测量对象,例如测量小区列表,测量感知目标多普勒范围,某一UE的DRB列表等。
数据收集标识,可以是基站配置的测量ID。
数据类型,可以是用户签约数据、网络运营数据、感知数据、AI数据中的一项或多项,也可以是具有数据提供标识的数据或没有数据提供功能节点标识的数据。
数据状态,用于指示数据处于数据生命周期中的哪一种情况,一种简化的数据生命周期定义方法是:包括生成期和使用期,生成期是指数据正在产生和收集中,使用期是指数据可以被各数据消费功能节点使用,数据可以处于生成期或使用期,也可以同时处于生成期和使用期。另一种数据生命周期定义方法是:包括生成期、活动期、衰退期、归档期和销毁期。其中,活动期、衰退期和归档期均是按照数据被访问的频率来进行定义的,例如访问频率高于第一阈值为活动(活跃)期;低于第二阈值并且高于第三阈值则为衰退期,进入衰退期后,数据活动日益减少,如果出现剧烈活动可能是非预期的,往往预示着数据价值的再发现或者数据安全性事件的发生;低于第三阈值则为归档期,此时数据的访问进入非常稀疏的阶段,并且数据不再更新。当数据已经没有使用上的价值或者已经超越了法规监管的周期,这个时候数据需要被销毁则称为销毁期。另一种数据生命周期的定义方法是:数据隐私和安全、数据生成和收集、数据存储、数据传输、数据处理、数据消费和数据质量管理等。根据数据处理的各个阶段进行划分定义的,例如数据正在生成和收集,那么数据收集控制功能节点可以通过修改现有的数据收集来提供第一数据;如果数据处于数据存储,那么数据收集控制功能节点可以通过数据存储功能节点来提供第一数据。
数据有效期,用于指示数据在多长时间内有效,例如第二功能节点节点根据存储空间大小和/或数据访问情况确定数据有效期。
一种以区域为目标的数据收集对应的数据摘要示例如下:
数据摘要标识:M;
数据项:RSRP、RSRQ、PDCP delay;
数据收集控制功能节点标识:RAN-DCF ID;
数据提供功能节点标识:RAN-DCF ID;
数据生成时间:每天11:00a.m.-12:00a.m.;

步骤2:第一功能节点根据授权信息确定数据消费功能节点是否可以访问所需的第一数据。如果可以访问,那么第一功能节点根据数据消费功能节点发送的第一数据请求和所获得的数据摘要信息,确定所需的第一数据是否正在收集或已经收集。如果不可以访问,第一功能节点可以发送拒绝响应消息给数据消费功能节点,可选的,拒绝响应消息中指示原因为鉴权失败。

UE发送所收集的数据至第三功能节点,并向第三功能节点指示所发送数据的数据摘要。一种指示方法是UE发送的数据中携带数据摘要标识。一种优化的指示方法是:UE在发送第一个数据包时至少包括对应的数据摘要标识,后续数据包通过指示信息说明是否属于前一个数据摘要。如果有多个数据收集同时进行时,为了避免数据传输乱序引起的数据摘要指示歧义,需要对不同的数据收集的数据包添加数据包序号,以便于区分不同的数据收集对应的数据包。
当第一功能节点接收到数据消费功能节点的数据请求,并且该数据请求需要由UE提供时,相关流程简述如下:
步骤1:第一功能节点接收数据消费功能节点的第一数据请求(第一数据请求可以是数据获取请求或数据订阅请求),所述第一数据请求包括以下至少一项:所述第一数据的数据项,所述第一数据的数据生成时间,所述第一数据的数据生成地点,所述第一数据对应的测量对象。
步骤2:第一功能节点根据授权信息确定数据消费功能节点是否可以访问所需的第一数据。如果可以访问,那么第一功能节点根据数据消费功能节点发送的第一数据请求和所获得的数据摘要信息,确定所需的第一数据是否正在收集或已经收集。如果不可以访问,第一功能节点可以发送拒绝响应消息给数据消费功能节点,可选的,拒绝响应消息中指示原因为鉴权失败。
当数据服务选项(即数据消费功能节点获得数据的方式)为通过消息框架(messaging framework或messaging bus,如卡夫卡等)获取数据时,其中存储UE数据的第三功能节点作为第二功能节点UE的代理对UE数据根据数据格式模板进行处理,并发布至消息框架。步骤3分为如下3种情况。
步骤3-1:如果所述第一数据的收集状态信息指示所述第一数据正在被第二功能节点UE收集或已经被第二功能节点UE收集,所述第一功能节点向发送所述第一数据请求的数据消费功能节点发送第一数据响应;所述第一数据响应包括以下至少一项:UE标识,第三功能节点标识,数据收集标识。第三功能节点发布数据至消息框架,数据消费功能节点基于消息框架获取所需的第一数据。
步骤3-2:如果所述第一数据的收集状态信息指示所述第一数据的第一部分数据正在被第二功能节点UE收集或已经被第二功能节点UE收集,所述第一功能节点向第二功能节点UE发送数据收集修改信息并修改所述第一部分数据对应的数据摘要(以匹配数据收集修改),所述数据收集修改信息用于指示所述UE收集所述第一数据的第二部分数据,所述第二部分数据为所述第一数据的第一部分数据之外的其他部分数据。例如数据消费功能节点请求X项数据,第二功能节点UE正在收集或已经收集的数据包括X项数据中的Y项数据(其中X>Y),那么第一功能节点发送数据收集修改信息给第二功能节点UE,指示第二功能节点UE收集所需的X-Y项数据,并且第一功能节点更新第二功能节点UE对应的数据 摘要,以匹配数据收集修改。可选的,第一功能节点发送数据消费功能节点所需数据的数据格式模板给第二功能节点UE或第三功能节点,第二功能节点UE或第三功能节点根据数据格式模板对第二功能节点UE所收集的数据处理产生满足数据消费功能节点需求的数据格式。第一功能节点发送第一数据响应给数据消费功能节点,第一数据响应至少包括以下至少一项:UE标识,第三功能节点标识和数据收集标识。第三功能节点发布数据至消息框架,数据消费功能节点基于消息框架获取所需的第一数据。
步骤3-3:如果所述第一数据的收集状态信息指示所述第一数据未被收集,所述第一功能节点确定用于收集所述第一数据的数据提供功能节点(如UE),并向所述用于收集所述第一数据的数据提供功能节点发送数据收集配置信息,所述数据收集配置信息包括以下至少一项:所述第一数据的数据项,所述第一数据的数据生成时间,所述第一数据的数据生成地点,所述第一数据对应的测量对象。可选的,所述第一功能节点还可以生成所对应的数据摘要信息,便于后续接收到后续数据请求时判断所请求的数据是否正在收集或已经收集。第一功能节点发送第一数据响应给数据消费功能节点,第一数据响应至少包括以下至少一项:第二功能节点标识、第三功能节点标识和数据收集标识。第三功能节点发布数据至消息框架,数据消费功能节点基于消息框架获取所需的第一数据。
当数据服务选项(即数据消费功能节点获得数据的方式)为通过第一功能节点获得数据时,步骤3分为如下3种情况。
步骤3-1:如果所述第一数据的收集状态信息指示所述第一数据正在被第二功能节点UE收集或已经被第二功能节点UE收集,所述第一功能节点向所述第三功能节点发送第三数据请求。所述第三数据请求包括:所述第一数据对应的数据摘要标识。第三功能节点根据数据摘要标识发送数据给第一功能节点。根据请求响应方式或者订阅方式,所述第一功能节点向发送数据消费功能节点发送第二数据响应或第一通知信息,所述第二数据响应包括所述第一数据,所述第一通知信息用于通知所述数据消费功能节点所述第一数据订阅成功。
步骤3-2:如果所述第一数据的收集状态信息指示所述第一数据的第一部分数据正在被第二功能节点UE收集或已经被第二功能节点UE收集,所述第一功能节点向第二功能节点UE发送数据收集修改信息并修改所述第一部分数据对应的数据摘要(以匹配数据收集修改),所述数据收集修改信息用于指示所述第二功能节点UE收集所述第一数据的第二部分数据,所述第二部分数据为所述第一数据的第一部分数据之外的其他部分数据,本申请实施例中,可选的,所述数据收集修改信息包括以下至少一项:数据摘要标识,新增的数据项。例如数据消费功能节点请求X项数据,第二功能节点UE正在收集或已经收集的数据包括X项数据中的Y项数据(其中X>Y),那么第一功能节点发送数据收集修改信息给第二功能节点UE,指示第二功能节点UE收集所需的X-Y项数据,并且第一功能节点更新第二功能节点UE对应的数据摘要,以匹配数据收集修改。可选的,第一功能节点发送数据消费功能节点所需数据的数据格式模板给第二功能节点UE或第三功能节点,第二功能节 点UE或第三功能节点根据数据格式模板对所收集的数据处理产生满足数据消费功能节点需求的数据格式。根据请求响应方式或者订阅方式,所述第一功能节点向发送数据消费功能节点发送第二数据响应或第一通知信息,所述第二数据响应包括所述第一数据,所述第一通知信息用于通知所述数据消费功能节点所述第一数据订阅成功。
步骤3-3:如果所述第一数据的收集状态信息指示所述第一数据未被收集,所述第一功能节点确定用于收集所述第一数据的数据提供功能节点(如UE),并向所述用于收集所述第一数据的数据提供功能节点发送数据收集配置信息,所述数据收集配置信息包括以下至少一项:所述第一数据的数据项,所述第一数据的数据生成时间,所述第一数据的数据生成地点,所述第一数据对应的测量对象。可选的,所述第一功能节点还可以生成所对应的数据摘要信息,便于后续接收到后续数据请求时判断所请求的数据是否正在收集或已经收集。可选的,第一功能节点发送数据消费功能节点所需数据的数据格式模板给第二功能节点或第三功能节点,第二功能节点或第三功能节点根据数据格式模板对所收集的数据处理产生满足数据消费功能节点需求的数据格式。根据请求响应方式或者订阅方式,所述第一功能节点向发送数据消费功能节点发送第二数据响应或第一通知信息,所述第二数据响应包括所述第一数据,所述第一通知信息用于通知所述数据消费功能节点所述第一数据订阅成功。
实施例3:
本实施例中,第一功能节点为核心网网络功能或无线接入网网络功能,第二功能节点为UE,由第三功能节点代理UE进行数据摘要注册和更新。
本实施例中,假设第一功能节点是核心网网络功能(如核心网数据控制功能(CN-DCF)),或者,无线接入网网络功能(如无线接入网数据控制功能(RAN-DCF))。
本实施例中,如果UE是汽车等具备本地数据存储的节点时,其流程与实施例1类似,不再本用例赘述。如果UE本地存储能力受限,所收集的数据需要上报到网络进行存储。假设第二功能节点UE正在收集数据和/或已经收集数据,并且所收集的数据由第三功能节点负责存储。那么,UE可以发送所收集的数据以及数据摘要至第三功能节点。所述数据摘要示例如下:
数据摘要标识:M;
数据项:RSRP、RSRQ、PDCP delay、QoE;
数据提供功能节点标识:UE ID;
数据生成时间:每天11:00a.m.-12:00a.m.;
数据生成地点:××办公楼;
数据对应的测量对象:下行链路;
数据收集标识:X;
数据类型:有UE标识的数据;
数据状态:生成期;
数据有效期:一个月。
进一步地,为了减少数据传输量。有如下方式可发送数据和数据摘要:
1)如果UE相同时间内只存在一个数据收集,那么UE在发送第一个数据包时至少包括数据摘要,后续数据包通过指示信息指示该数据是否属于前一个数据摘要关联。
2)如果UE在相同时间内存在多个数据收集,UE在发送第一个数据包时至少包括数据摘要,后续数据包仅携带数据摘要标识指示该数据与数据摘要的关联关系。
第三功能节点接收到数据摘要后,将所述数据摘要发送给第一功能节点,注册UE作为第二功能节点正在收集或已经收集的数据信息。
当第一功能节点接收到数据消费功能节点的数据请求时,并且该数据请求需要由UE提供时,相关流程与实施例2相同,不再赘述。
实施例4:
本实施例中涉及核心网或无线接入网内部的数据收集。
本实施例中,考虑第一功能节点与第二功能节点同属于核心网网络功能,或者第一功能节点与第二功能节点同属于无线接入网网络功能。例如,第一功能节点为核心网数据控制功能(CN-DCF),第二功能节点为AMF、SMF、NWDAF、ADRF等核心网网络功能。或者,第一功能节点为无线接入网数据控制功能(RAN-DCF),第二功能节点为CU-CP,CU-UP、DU等无线接入网网络功能。
如果数据收集是由CN-DCF或RAN-DCF控制收集,那么CN-DCF或RAN-DCF可以自行生成和维护数据摘要,不涉及网络功能间的交互。本实施例中,侧重考虑现有CP或UP功能配置进行的收据收集,例如NWDAF可以收集核心网网络功能的数据,CU-CP可以收集无线接入网的L3测量等。下方流程以无线接入网内部的数据收集为例进行简述,因为通常作为第二功能节点的无线接入网网络功能CU-CP,CU-UP或DU的存储空间受限,对应的数据有效期较短。如果RAN-DCF可根据数据摘要和数据价值分析,从第二功能节点获取数据以延长数据有效期,可以为潜在的数据复用提供更长期的历史数据。
相关流程简述如下:
步骤1:可选的,第一功能节点向第二功能节点发送数据摘要配置信息,所述数据摘要配置信息包括数据摘要的更新周期和触发数据摘要更新的事件配置信息中的至少一项。所述触发数据摘要更新的事件配置信息例如为出现某一数据生成地点时发送数据摘要,或者,出现某一数据提供功能节点的数据时发送数据摘要。
在本申请的其他一些实施例中,第二功能节点也可以根据网络管理功能的配置信息,获取所述第一功能节点的标识和所述数据摘要配置信息。
步骤2:第二功能节点根据数据摘要配置信息向第一功能节点发送数据摘要注册或数据摘要更新。所述数据摘要注册或数据摘要更新中包括数据摘要。
其中,数据摘要包括以下至少一项:
数据摘要标识,例如M。
数据项,例如RSRP、RSRQ、PDCP delay。
数据收集控制功能节点标识,例如CU-CP ID,CU-UP ID,DU ID。
数据提供功能节点标识,例如CU-CP ID,CU-UP ID,DU ID。
数据生成时间,用于指示数据生成的时间。
数据生成地点,如果是第二功能节点测量上行信号产生的数据,因为基站位置通常固定,所以可以不包括数据生成地点或仅提供一次该信息。
数据对应的测量对象,例如测量小区列表,测量感知目标多普勒范围,某一UE的DRB列表等。
数据收集标识,可以是基站配置的测量ID。
数据状态,因为CU-CP,CU-UP或DU的有效期通常在传输时间间隔(Transmission Time Interval,TTI)或几十个TTI区间,通常数据状态为生成期或者使用期。如果进一步细分,数据状态也可能处于衰减期。
数据有效期,有效期通常在TTI或几十个TTI区间。
步骤3:第一功能节点接收第二功能节点发送的数据摘要,从而获取所控制的所有第二功能节点正在收集或已经收集的数据的信息。
当第一功能节点接收到数据消费功能节点的数据请求时,相关流程与实施例1相同。本实施例主要阐述第一功能节点根据历史数据请求信息分析潜在的数据可能会被复用,根据数据摘要获取对应数据进行更长期的数据存储。相关流程简述如下:
步骤1:第一功能节点确定需要更长期存储的第二数据,发送第四数据请求给第二功能节点,所述第四数据请求用于更新第二数据的数据有效期,所述第二数据为所述第二功能节点正在收集或已经收集的并由所述第二功能节点存储的数据,所述第四数据请求包括以下至少一项:数据摘要标识,数据存储功能节点ID。
步骤2:第二功能节点根据第四数据请求发送第二数据给第一功能节点,或者,发送第二数据给数据存储功能节点。
步骤3:第一功能节点确定第二数据的数据有效期(将数据有效期延长),并更新数据摘要中的第二数据的数据有效期以及数据提供功能节点标识。如果第一功能节点接收第二数据,那么数据提供功能节点标识为第一功能节点标识,如果数据存储功能节点接收第二数据,那么数据提供功能节点标识为数据存储功能节点标识。
本申请实施例中,通过数据摘要的方式,大部分情况无需发送数据本身,既实现一定程度上的不同域的数据隔离,也减少数据传输量。面向存储能力受限的UE,或者数据收集和数据存储解耦的网络架构,还支持数据摘要注册节点与数据提供节点不同的情况,也支持数据提供节点代理数据收集节点注册数据摘要。扩展支持了数据收集节点和数据摘要注册节点不同的情况,避免了跨域数据共享时不必要的域内信息共享,既提供了安全性,也简化了跨域数据共享。由核心网第一功能节点统一接收数据摘要信息的情况下,提供了对数据消费功能节点更加友好的数据服务,避免数据消费功能节点维护所需数据与数据控制 功能之间的映射关系。
