需要说明的是,所述NRF代表的是网络仓储功能网元,也可以是其他具有存储功能的网元、设备等。所述NWDAF(MTLF)是指NWDAF中Model Training logical function(MTLF),具有模型训练能力的设备,也可以是指其他具有模型训练能力的设备,或者其他需要获取数据的设备等。所述LMF是指location management function,辅助位置管理的设备,该设备可以收集到位置信息,也可以是指其他可提供数据的设备等,如NWDAF等。ADRF是指(Analytics Data Repository Functional,分析数据存储功能网元),可以是指具有数据存储功能的设备等。
具体地,本申请实施例提供的数据获取方法可以包括以下步骤:
步骤0、LMF可能生成一个数据标识信息(如DataSetTag)以便后续进行数据存储时,描述数据和标识数据。
步骤1、LMF将数据存储至ADRF中。具体地,LMF可能通过Nadrf_DataManagement_Storage Request(Nadrf数据管理存储请求)等服务向ADRF发送数据存储请求,请求将数据存储到ADRF中。其中,LMF可以根据自身运行逻辑,在收集或生成数据后向ADRF发送数据存储请求,实时存储收集或生成的数据;或者,按照预设周期定期向ADRF发送数据存储请求;或者,LMF可以由其他设备触发,向ADRF发送数据存储请求。

需要说明的是,当LMF的数据存储请求中携带有DataSetTag时,ADRF可能会将一个DataSetTag依据数据的不同,再次将数据分开并分配新的DataSetTag,即接收到一个DataSetTag,但是会反馈一个或多个DataSetTag。
步骤3、NWDAF向NRF发送网元查找请求,请求查找到可提供所需数据的网元。例如,NWDAF可通过Nnrf_NFDiscovery_Request service等向NRF发送网元查找请求。该王元查找请求需携带网元类型(用于指示所查找的网元类型,如LMF网元等)、区域信息(用于指示所查找的网元的服务范围等)、能力信息(具有支持提供定位相关数据的能力,或者可提供的数据信息(如所支持的event ID等))中的至少一项。

或者,LMF向NRF注册其支持的服务,例如数据收集服务(该服务说明LMF支持其他设备向LMF发送数据获取请求相关的服务等)、数据开放服务(该服务说明LMF支持其他设备通过该服务获取数据)等。
NRF接收LMF的注册信息。
NRF存储LMF支持的能力、服务。
NRF向LMF发送注册结果,以告知LMF已经接收其发送的注册消息,并存储了LMF的能力信息、服务信息等。
NWDAF等consumer向NRF查找网元(例如LMF)时,还可以基于在网元查找请求中携带能力和服务中的至少一项对应的指示信息,NRF根据王元查找请求中的指示信息查找支持对应的能力和/或服务的网元。

数据粒度信息,用于指示将请求的数据的粒度,如:高、中、低;大、中、小;粗、中、细;全部、一般(中等)、一部分等;具体的表示粒度的用词可能有所不同,但所示含义类似,即指示不同粒度的数据或者不同的数据。另一种表示方法还有可能是,通过不同的数据类型信息等方式表示该粒度信息,例如,在定位相关的数据获取中可能是:定位相关数据(较粗的粒度),UE测量数据(中等粒度),UE位置数据(较细的粒度);
数据类型信息,用于指示将请求的数据的类型,该数据类型可以是直接的数据类型,如UE测量数据,RSRP(接收信号参考功率(Reference Signal Received Power)),RSTD(接收信号时延差(Reference Signal Time Difference)),CIR(指信道冲激响应(Channel Impulse Response))等,也可以是event ID等方式表示;需要说明的是,数据类型信息也可以指示产生数据的设备,如UE测量数据中,数据产生者即为UE;
时间信息,用于指示将请求的数据的时间信息,如某个时间范围内的数据;
区域信息,用于指示将请求的数据的地理区域信息,如某个区域范围内的数据;该区域可以是cell ID,或者经纬度信息等。
步骤5、NRF反馈access token信息。具体地,NRF基于步骤4中令牌获取请求中的设备信息(NWDAF的设备信息)和期望的服务信息等信息判断该设备是否具有该服务的权限等信息。若该设备具有使用该服务的权限,则会向NWDAF反馈token信息。
需要说明的是,某些情况下,如当期望的服务信息是数据获取相关的服务时,NRF会进一步的判断该设备是否具有数据获取服务对应的数据粒度、数据类型、时间、区域等信息的权限;若该设备具有使用该服务的权限,则会向NWDAF反馈token信息,和/或对应的数据粒度、数据类型、时间、区域等信息。
若该设备不具有相对应的权限,则NRF无法给该NWDAF授权,可能会反馈相对应的失败响应信息;又或者,可能会反馈该NWDAF的权限范围内的token信息和/或数据类型、数据类型、时间、区域等信息。
需要说明的是,上述数据粒度信息,数据类别信息等还可以通过token信息指示而不是单独的信元,即隐含指示,如token信息中的某个字节进行指示等。

步骤7、LMF对NF服务消费者进行身份验证。具体地,LMF验证访问令牌,可能是通过和NRF交互确定token的完整性等,并确保access token中能包含所示数据类型、数据粒度等。
如果验证成功,LMF将确定可反馈请求的数据,并将NWDAF的实例ID存储为可获取数据的NF实例列表的一部分。
步骤8-9、LMF可重用数据存储服务,以更新可获取该数据的设备列表信息,具体实现过程如步骤1-2。
需要说明的是,在更新可获取数据的设备列表时,数据存储请求中可新增可携带的参数为存储标识信息,例如Storage Transaction ID。
步骤10、LMF向NWDAF反馈数据请求的结果。具体地,LMF向NWDAF发送响应消息,响应数据请求消息。可通过该响应消息告知NWDAF其所请求的数据所存储的位置,对应的标识等;该消息可携带以下至少一项:

存储标识信息,可通过该标识信息确定一个数据集,例如Storage Transaction ID;
设备标识信息,用于指示数据存储设备,例如ADRFID,ADRF的标识信息;该信息也可以是其他设备标识信息,如其他数据存储设备。
需要说明的是,DataSetTag和Storage Transaction ID对应的数据可能是不同粒度和不同数据类型进行区分的,如一个DataSetTag/Storage Transaction ID可能对应一种数据类型,当所请求的数据为多种数据类型时,可以反馈多个DataSetTag/Storage Transaction ID。
步骤11-12、该步骤和步骤4-5类似,NWDAF通过和NRF交互,获取到可向ADRF请求获取数据的access token信息,以便后续向ADRF发送数据获取请求,请求获取数据等。

步骤0、LMF可能生成一个数据标识信息(如DataSetTag)以便后续进行数据存储时,描述数据和标识数据。
步骤1、LMF将数据存储至ADRF中。具体地,LMF可能通过Nadrf_DataManagement_Storage Request(Nadrf数据管理存储请求)等服务向ADRF发送数据存储请求,请求将数据存储到ADRF中。其中,LMF可以根据自身运行逻辑,在收集或生成数据后向ADRF发送数据存储请求,实时存储收集或生成的数据;或者,按照预设周期定期向ADRF发送数据存储请求;或者,LMF可以由其他设备触发,向ADRF发送数据存储请求。
其中,该数据存储请求中可携带需存储的数据、LMF ID(即LMF自身的设备标识信息),数据标识信息(如DataSetTag)、数据描述信息、可获取数据的设备列表(如网络功能实例列表)等。需要说明的是,可获取数据的设备列表也可以是该LMF授权/同意获取数据的设备列表;另一方面,该列表可以是多个设备的标识信息,或者厂商信息等。
步骤2、ADRF反馈存储结果。ADRF接收到来自于LMF的数据存储请求后,反馈数据存储结果。具体地,当LMF的数据存储请求中没有携带DataSetTag时,ADRF可能会反馈Storage Transaction ID(存储事务标识)以便标识该数据;当LMF的数据存储请求中有携带DataSetTag时,ADRF可能会使用并反馈该DataSetTag作为数据标识。
需要说明的是,当LMF的数据存储请求中携带有DataSetTag时,ADRF可能会将一个DataSetTag依据数据的不同,再次将数据分开并分配新的DataSetTag,即接收到一个DataSetTag,但是会反馈一个或多个DataSetTag。
步骤3、NWDAF向NRF发送网元查找请求,请求查找到可提供所需数据的网元。例如,NWDAF可通过Nnrf_NFDiscovery_Request service等向NRF发送网元查找请求。该王元查找请求需携带网元类型(用于指示所查找的网元类型,如LMF网元等)、区域信息(用于指示所查找的网元的服务范围等)、能力信息(具有支持提供定位相关数据的能力,或者可提供的数据信息(如所支持的event ID等))中的至少一项。
此外,LMF向NRF注册其支持的能力,例如数据收集能力、被动数据收集的能力(该能力说明LMF支持被动收集数据)、数据开放能力等。
或者,LMF向NRF注册其支持的服务,例如数据收集服务(该服务说明LMF支持其他设备向LMF发送数据获取请求相关的服务等)、数据开放服务(该服务说明LMF支持其他设备通过该服务获取数据)等。
NRF接收LMF的注册信息。
NRF存储LMF支持的能力、服务。
NRF向LMF发送注册结果,以告知LMF已经接收其发送的注册消息,并存储了LMF的能力信息、服务信息等。
NWDAF等consumer向NRF查找网元(例如LMF)时,还可以基于在网元查找请求中携带能力和服务中的至少一项对应的指示信息,NRF根据王元查找请求中的指示信息查找支持对应的能力和/或服务的网元。

需要说明的是,某些情况下,如当期望的服务信息是数据获取相关的服务时,令牌获取请求还可携带以下至少一项:
数据粒度信息,用于指示将请求的数据的粒度,如:高、中、低;大、中、小;粗、中、细;全部、一般(中等)、一部分等;具体的表示粒度的用词可能有所不同,但所示含义类似,即指示不同粒度的数据或者不同的数据。另一种表示方法还有可能是,通过不同的数据类型信息等方式表示该粒度信息,例如,在定位相关的数据获取中可能是:定位相关数据(较粗的粒度),UE测量数据(中等粒度),UE位置数据(较细的粒度);
数据类型信息,用于指示将请求的数据的类型,该数据类型可以是直接的数据类型,如UE测量数据,RSRP(接收信号参考功率(Reference Signal Received Power)),RSTD(接收信号时延差(Reference Signal Time Difference)),CIR(指信道冲激响应(Channel Impulse Response))等,也可以是event ID等方式表示;需要说明的是,数据类型信息也可以指示产生数据的设备,如UE测量数据中,数据产生者即为UE;
时间信息,用于指示将请求的数据的时间信息,如某个时间范围内的数据;
区域信息,用于指示将请求的数据的地理区域信息,如某个区域范围内的数据;该区域可以是cell ID,或者经纬度信息等。
步骤5、NRF反馈access token信息。具体地,NRF基于步骤4中令牌获取请求中的设备信息(NWDAF的设备信息)和期望的服务信息等信息判断该设备是否具有该服务的权限等信息。若该设备具有使用该服务的权限,则会向NWDAF反馈token信息。
需要说明的是,某些情况下,如当期望的服务信息是数据获取相关的服务时,NRF会进一步的判断该设备是否具有数据获取服务对应的数据粒度、数据类型、时间、区域等信息的权限;若该设备具有使用该服务的权限,则会向NWDAF反馈token信息,和/或对应的数据粒度、数据类型、时间、区域等信息。
若该设备不具有相对应的权限,则NRF无法给该NWDAF授权,可能会反馈相对应的失败响应信息;又或者,可能会反馈该NWDAF的权限范围内的token信息和/或数据类型、数据类型、时间、区域等信息。
需要说明的是,上述数据粒度信息,数据类别信息等还可以通过token信息指示而不是单独的信元,即隐含指示,如token信息中的某个字节进行指示等。
步骤6、NWDAF向LMF发送数据获取请求消息,请求获取目标数据。具体地,该数据获取请求消息可以是eventExpose(事件曝光)相关的服务,或者专门的数据获取服务等。该消息中可以携带以下至少一项:
Token信息,步骤5中NRF授权的token信息;
请求获取数据的指示信息,用于指示该消息是请求获取数据,如请求获取定位相关数据的指示信息等;

数据粒度信息,用于指示所请求的数据的粒度;
NWDAF的设备信息;
NWDAF的认证信息,如CCA信息。
步骤7、LMF对NF服务消费者进行身份验证。具体地,LMF验证访问令牌,可能是通过和NRF交互确定token的完整性等,并确保access token中能包含所示数据类型、数据粒度等。
如果验证成功,LMF将确定可反馈请求的数据,并将NWDAF的实例ID存储为可获取数据的NF实例列表的一部分。
步骤8-9、LMF可重用数据存储服务,以更新可获取该数据的设备列表信息,具体实现过程如步骤1-2。
需要说明的是,在更新可获取数据的设备列表时,数据存储请求中可新增可携带的参数为存储标识信息,例如Storage Transaction ID。
步骤10、LMF向NWDAF反馈数据请求的结果。具体地,LMF向NWDAF发送响应消息,响应数据请求消息。可通过该响应消息告知NWDAF其所请求的数据所存储的位置,对应的标识等;该消息可携带以下至少一项:
数据标识信息,可通过该标识信息确定一个数据集,该标识信息的具体表现形式可以说DataSetTag;
存储标识信息,可通过该标识信息确定一个数据集,例如Storage Transaction ID;
设备标识信息,用于指示数据存储设备,例如ADRFID,ADRF的标识信息;该信息也可以是其他设备标识信息,如其他数据存储设备。
需要说明的是,DataSetTag和Storage Transaction ID对应的数据可能是不同粒度和不同数据类型进行区分的,如一个DataSetTag/Storage Transaction ID可能对应一种数据类型,当所请求的数据为多种数据类型时,可以反馈多个DataSetTag/Storage Transaction ID。
步骤11-12、该步骤和步骤4-5类似,NWDAF通过和NRF交互,获取到可向ADRF请求获取数据的access token信息,以便后续向ADRF发送数据获取请求,请求获取数据等。
步骤13-14、NWDAF向ADRF发送数据获取请求,请求获取数据标识信息所对应的数据。具体地,NWDAF可通过Nadrf_DataManagement_RetrievalRequest Request等服务向ADRF发送数据获取请求,可携带以下至少一项:自身设备信息(如自身设备的标识信息,类型信息等),数据标识信息(如DataSetTag,Storage Transaction ID等),token信息等。
ADRF可基于数据标识信息确定所要提供的数据。
ADRF还可以基于NWDAF的设备信息和步骤1或步骤8中的可获取数据的设备列表信息确定该NWDAF是否可以获取该数据。
该token信息可以被用来验证该NWDAF设备的身份等。
