具体实施方式
下文中将结合附图对本申请的实施例进行说明。
在5G网络中，引入了NWDAF，NWDAF能够从其他网络功能中采集网络数据，并对网络数据进行分析后反馈网络数据分析结果。如图1所示，图1为5G网络自动化总体框架示意图。图1中描述了NWDAF从运营商OAM、AF、和其他5G网络功能中采集数据。对于OAM数据的采集，NWDAF可以复用第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)定义的机制和接口。AF可以根据网络部署情况，通过网络开放功能(Network Exposure Function，NEF)与NWDAF进行信息交互，或者使用基于业务的接口直接访问NWDAF。NWDAF可以从数据存储库访问网络数据，如统一数据存储(Unified Data Repository，UDR)。对于3GPP的NF，NWDAF利用基于3GPP定义的业务的接口通信获取网络数据。基于上述数据采集，NWDAF进行数据分析，并将分析结果提供给AF、3GPP NF和OAM。
主要的3GPP的网络功能NFs(Network Funtions)包括但不限于下列各种网络功能类型：接入管理功能(Access Management Function，AMF)属于核心网内的公共控制面功能，终结所有用户与网络之间的非接入层(Non Access Stratum，NAS)消息。一个用户设备(User Equipment，UE)只有一个AMF，负责：用户移动性管理，UE状态(如可达性)管理等。会话管理功能(Session Management Function，SMF)，负责会话建立、修改、删除，控制PCF收费和策略的执行等功能；策略控制功能(Policy Control Function，PCF)，负责根据用户的签约、UE当前的位置、应用相关的信息为终端制定策略，包括路由策略、服务质量策略、计费策略等。统一数据管理(Unified Data Management，UDM)：具有统一数据管理功能，用户签约数据的永久存放等功能；统一数据存储(Unified Data Repository，UDR)：主要用于存储UDM和PCF管理的用户签约数据、策略数据等。UPF(User Plane Function)属于核心网内用户面的功能，是核心网用户面的锚点，是与外部数据网络(Data Network，DN)数据传输的接 口，执行用户面部分PCF策略规则的执行等；(Network Exposure Function，NEF)用于暴露3GPP NFs的能力和事件给其他NF或者外部AF，提供AF预配置3GPP NFs能力，实现3GPP网络和外部网络信息映射等；AF指接入3GPP的应用；网络存储功能(Network Repository Function，NRF)：维护NF文件夹(NF文件夹包括NF实体和其所支持的业务描述)，支持业务发现功能等；NWDAF：网络数据分析功能，支持从NF、AF、OAM收集数据，业务注册和元数据暴露给NF/AF，分析结果暴露给NF/AF/OAM；OAM可以是核心网的OAM，和/或接入网(Radio Access Network，RAN)的OAM。
但是在实际部署当中，NWDAF网络功能可能需要按照服务区域进行部署，例如按照切片部署、按照地理位置(省、市)部署，不同的运营商也各自部署自己的NWDAF。这种场景下，不同的NWDAF服务于不同的区域，服务于不同的网络功能，所以采集不同网络功能的数据需要通过不同NWDAF来实现，不利于网络的统一管理和应用。
图2为一实施例提供的一种网络数据采集方法的流程图，如图2所示，本实施例提供的方法包括如下步骤。
步骤S2010，源NWDAF向目标NWDAF发送网络功能数据采集请求，网络功能数据采集请求包括至少一个网络功能的数据采集辅助参数。
本实施例提供的网络数据采集应用于无线通信网络中的NWDAF，NWDAF是网络中的一种逻辑功能，可以部署于网络中的任一个网络设备中，或者NWDAF为网络中的一个独立设备。在无线通信网络中，不同运营商需要在各自的网络中分别部署独立的NWDAF，同一个运营商为了便于管理，也会根据地理位置或者网络的切片在网络中部署多个NWDAF。根据图1所示架构图可知，NWDAF仅能在归属的网络中对各种NF的数据进行采集和分析。
本实施例提供的网络数据采集方法，由网络中的一个NWDAF所执行，将其称为源NWDAF。若源NWDAF需要采集数据的网络功能并不在源NWDAF的服务区域内，那么源NWDAF将无法直接采集该网络功能的网络数据。此时源NWDAF需要通过目标NWDAF采集所述网络功能的网络数据。目标NWDAF是为所述网络功能服务的NWDAF，也就是所述网络功能是位于目标NWDAF的服务区域的网络功能。源NWDAF可以根据其他网络功能的指示采集所述网络功能的网络数据。向NWDAF发送业务请求的网络功能可以称为NWDAF消费者，NWDAF消费者包括使用NWDAF的任一种业务能力的网络功能，例如图1中所示的各NF、AF、OAM等。源NWDAF需要采集网络数据的网络功能可能为一个或多个，其中位于目标NWDAF服务区域的网络功能也可能为一个或多个。另外，源NWDAF需要采集网络数据的网络功能还可能位于多个 NWDAF的服务区域内。那么网络功能数据采集请求还可以同时到多个目标NWDAF中采集多个网络功能的网络数据。网络功能数据采集请求包括需要采集数据的至少一个网络功能的数据采集辅助参数。至少一个网络功能分别位于多个目标NWDAF服务区域内。目标NWDAF的数量可能为多个，但源NWDAF在每个目标NWDAF中采集数据的方法均相同。
网络功能数据采集请求包括请求采集数据的至少一个网络功能的数据采集辅助参数。至少一个网络功能的数据采集辅助参数包括以下信息中的至少一种：网络功能的寻址信息、网络功能的数据采集策略、网络功能所需采集数据内容、网络功能的采集数据接收对象。其中，网络功能的寻址信息用于确定网络功能的位置，例如包括网络功能的标识、IP地址、端口号等能够确定网络功能的标识信息；网络功能的数据采集策略，例如网络功能的时间要求等；网络功能所需采集数据内容，表示需要到网络功能采集的数据内容；网络功能的采集数据接收对象表示采集到的数据的接受者。若网络功能为多个，则网络功能数据采集请求中可以同时包括多个网络功能的数据采集辅助参数。
步骤S2020，源NWDAF接收目标NWDAF发送的网络功能数据采集响应，网络功能数据采集响应包括至少一个网络功能反馈的网络数据。
当目标NWDAF接收到源NWDAF发送的网络功能数据采集请求后，可以采集至少一个网络功能的网络数据。目标NWDAF根据源NWDAF发送的网络功能数据采集的指示，采集所需的至少一个网络功能的网络数据，然后生成网络功能数据采集响应反馈给源NWDAF。那么当源NWDAF接收到网络功能数据采集响应后，将获知所需采集的至少一个网络功能反馈的网络数据，从而实现了跨NWDAF的网络数据采集。那么网络中部署于任意位置的NWDAF消费者，都可以通过所属区域的NWDAF对整个网络中的网络功能的网络数据进行采集，提高了网络数据采集的效率，为无线网络的统一管理和运行提供了基础。
本实施例提供的网络数据采集方法，由源NWDAF向目标NWDAF发送网络功能数据采集请求，网络功能数据采集请求包括请求采集数据的至少一个网络功能的数据采集辅助信息，然后接收目标NWDAF发送的网络功能数据采集响应，网络功能数据采集响应包括至少一个网络功能反馈的网络数据，使网络中部署于任意位置的NWDAF消费者，都可以通过所属区域的NWDAF对整个网络中的网络功能的网络数据进行采集，提高了网络数据采集的效率，为无线网络的统一管理和运行提供了基础。
图3为一实施例提供的另一种网络数据采集方法的流程图，如图3所示，本实施例提供的方法包括如下步骤。
步骤S3010，源NWDAF向NRF发送查询请求消息，查询请求消息包括 NWDAF选择辅助信息，NWDAF选择辅助信息包括至少一个网络功能的归属信息。
由于源NWDAF所需采集数据的至少一个网络功能不是位于源NWDAF的服务区域，因此源NWDAF无法直接对至少一个网络功能的网络数据进行采集。NRF为网络中存储各种网络功能相关数据的功能，各网络功能与NWDAF的对应关系也存储于NRF中。那么源NWDAF在需要采集至少一个网络功能的网络数据之前，可以先向NRF发送查询请求消息，其中，查询请求消息包括NWDAF选择辅助信息，NWDAF选择辅助信息包括至少一个网络功能的归属信息，那么NRF接收到查询请求消息后，可以根据至少一个网络功能的归属信息确定至少一个网络功能位于哪个NWDAF的服务区域。
NWDAF选择辅助信息是用于辅助选择至少一个网络功能所属NWDAF的相关信息，包括至少一个网络功能的归属信息。NWDAF选择辅助信息还可以包括NWDAF的网络功能类型。NWDAF选择辅助信息包括以下信息中的至少一种：网络功能的切片信息、网络功能的标识、网络功能的位置信息。其中，网络功能的切片信息表示网络功能归属的切片信息，例如：通过NWDAF服务的切片信息和网络功能的切片信息，可以判断网络功能是否在该NWDAF服务区域内；网络功能的标识，表示各种网络功能信息，例如网络功能标识或AF标识或OAM标识等；网络功能的位置信息，表示至少一个网络功能的地理位置、跟踪区域、网络协议(Internet Protocol，IP)地址、小区、运营商信息、厂商信息等有效区分服务区域的信息。
步骤S3020，源NWDAF接收NRF发送的查询响应消息，查询响应消息包括目标NWDAF的信息，至少一个网络功能位于目标NWDAF服务区域内。
NRF在接收到源NWDAF发送的查询请求消息后，将根据NWDAF选择辅助信息查询至少一个网络功能所属NWDAF的信息，即目标NWDAF的信息。例如NRF根据查询请求消息的网络功能的标识查询到服务于该网络功能标识的NWDAF；或者根据网络功能的切片信息或位置信息查询到服务于该切片或该位置的NWDAF，然后根据它们之间的关联关系确定服务于网络功能的NWDAF。随后源NWDAF将接收到NRF发送的查询响应消息，查询响应消息包括目标NWDAF的信息。目标NWDAF的信息例如包括目标NWDAF标识和/或目标NWDAF的能力信息等。
在一实施例中，目标NWDAF为多个，那么查询响应消息包括多个目标NWDAF的信息，所述至少一个网络功能分别位于所述多个目标NWDAF服务区域内。也就是说，源NWDAF向NRF发送的查询请求消息可以同时查询多个网络功能所属的NWDAF，且多个网络功能所属的NWDAF可以不同。那么相 应地，NRF向源NWDAF发送的查询响应消息中包括多个目标NWDAF的信息。也就是说，NRF可以在一个查询响应消息中向源NWDAF反馈多个不同目标NWDAF的信息，NRF还可以在多个不同的查询响应消息中分别向源NWDAF反馈多个不同目标NWDAF的信息。
步骤S3030，源NWDAF向目标NWDAF发送网络功能数据采集请求，网络功能数据采集请求包括至少一个网络功能的数据采集辅助信息。
步骤S3040，源NWDAF接收目标NWDAF发送的网络功能数据采集响应，网络功能数据采集响应包括至少一个网络功能反馈的网络数据。
在查询到目标NWDAF的信息后，源NWDAF即可向目标NWDAF发送网络功能数据采集请求，并接收目标NWDAF发送的网络功能数据采集响应，从而采集到网络功能反馈的网络数据。若源NWDAF通过查询请求消息查询到多个NWDAF的信息，那么源NWDAF可以分别向多个不同的NWDAF发送网络功能数据采集请求，并分别接收多个目标NWDAF发送的网络功能数据采集响应，从而可以从多个不同的NWDAF接收到所需采集的网络功能反馈的网络数据。
在一实施例中，源NWDAF向NRF发送查询请求消息之前，还包括源NWDAF判断是否能够直接采集至少一个网络功能的网络数据。
图4为一实施例提供的另一种网络数据采集方法的流程图，如图4所示，本实施例提供的方法包括如下步骤。
步骤S4010，源NWDAF接收NWDAF消费者发送的业务分析请求。
NWDAF消费者包括使用源NWDAF的任一种业务能力的网络功能。NWDAF消费者需要对网络中的任一种业务进行分析时，源NWDAF接收NWDAF消费者发送的业务分析请求。或者源NWDAF接收NWDAF消费者发送的订阅消息。业务分析请求和订阅消息中至少包括以下参数组合：业务类型，分析目标关联信息，分析结果通知对象。分析目标关联信息是用来确定分析业务类型所需采集数据的网络功能的辅助信息，例如：位置信息或网络功能标识或UE标识或AF标识或切片信息或其他可以用于辅助确定分析目标的关联信息。
步骤S4020，源NWDAF根据业务分析请求确定所需采集数据的至少一个网络功能的数据采集辅助参数。
源NWDAF接收到业务分析请求后，确定本次业务分析请求需要到哪些网络功能采集数据进行业务分析。例如，源NWDAF可以根据分析业务类型确定需要采集数据的网络功能类型，根据分析目标关联信息到UDM或NRF或绑定 支持功能(Binding Support Function，BSF)或AMF或NEF确定需要采集数据的网络功能。源NWDAF对业务分析请求进行分析后，确定的需要采集数据的网络功能可能为多个，并且多个网络功能可能位于不同的目标NWDAF的服务区域。源NWDAF可以向NRF发送查询请求，获取各NWDAF的信息，并进行数据的采集。其中，所需采集数据的网络功能包括至少一个网络功能，也就是以目标NWDAF服务区域的至少一个网络功能为例进行说明，位于其他NWDAF服务区域的网络功能的数据采集方法相同。
步骤S4030，源NWDAF判断是否能够直接采集至少一个网络功能的网络数据。
步骤S4040，若源NWDAF无法直接采集至少一个网络功能的网络数据，则源NWDAF向NRF发送查询请求消息。
步骤S4050，源NWDAF向NRF发送查询请求消息，查询请求消息包括NWDAF选择辅助信息，NWDAF选择辅助信息包括至少一个网络功能的归属信息。
在本实施例中，源NWDAF和目标NWDAF都已经注册到NRF中。源NWDAF和目标NWDAF可以归属于同一公共陆地移动网络(Public Land Mobile Network，PLMN)，也可以是归属于不同的PLMN。在本实施例中，假设网络功能位于目标NWDAF的服务区域，不位于源NWDAF服务区域。本实施例中的至少一个网络功能表示3GPP网络功能NF、AF、OAM等。
步骤S4060，源NWDAF接收NRF发送的查询响应消息，查询响应消息包括目标NWDAF的信息，至少一个网络功能位于目标NWDAF服务区域内。
步骤S4070，源NWDAF向目标NWDAF发送网络功能数据采集请求，网络功能数据采集请求包括至少一个网络功能的数据采集辅助参数。
步骤S4080，源NWDAF接收目标NWDAF发送的网络功能数据采集响应，网络功能数据采集响应包括至少一个网络功能反馈的网络数据。
步骤S4090，源NWDAF进行业务分析处理并向NWDAF消费者发送业务分析结果。
当源NWDAF接收到网络功能数据采集响应后，可以获取到至少一个网络功能反馈的网络数据，源NWDAF根据接收到的数据进行业务分析处理，得到业务分析结果，然后向NWDAF消费者发送业务分析结果，从而完成了跨NWDAF的业务分析。若源NWDAF需要到位于多个不同NWDAF的网络功能采集数据，则源NWDAF在接收到所有需要采集数据的网络功能反馈的数据后，再进行业务分析处理，然后可以得到分析结果。这样网络中的各种网络功能， 可以在网络中的任一位置进行业务分析，实现了网络的集中管理和运行。
在一实施例中，当源NWDAF在网络中注册时或者进行更新时，源NWDAF向NRF发送注册请求消息或更新请求消息，注册请求消息或更新请求消息包括源NWDAF的服务区域信息。NWDAF的服务区域信息包括以下信息中的至少一种：NWDAF服务的切片信息、NWDAF服务的网络功能标识、NWDAF服务的位置信息。注册请求消息或更新请求消息还包括以下信息中的至少一种：NWDAF的网络功能类型、NWDAF的网络功能标识、NWDAF支持的业务能力、NWDAF的归属运营商标识。
图5为一实施例提供的另一种网络数据采集方法的流程图，如图5所示，本实施例提供的方法包括如下步骤。

步骤S5020，NRF向源NWDAF发送查询响应消息，查询响应消息包括目标NWDAF的信息，至少一个网络功能位于目标NWDAF服务区域内。
本实施例提供的网络数据采集应用于无线通信网络中的NRF，NRF是网络中的一种逻辑功能，可以部署于网络中的任一个网络设备中，或者NRF为网络中的一个独立设备。在无线通信网络中，不同运营商需要在各自的网络中分别部署独立的NWDAF，同一个运营商为了便于管理，也会根据地理位置或者网络的切片在网络中部署多个NWDAF。根据图1所示架构图可知，NWDAF仅能在归属的网络中对其服务区域内各种NF的数据进行采集和分析。
为了实现多个NWDAF之间的网络数据采集，各NWDAF需要能够获知所需采集数据的网络功能在哪个NWDAF的服务区域内。NRF为网络中存储各种网络功能相关数据的功能，其中各网络功能与NWDAF的对应关系也存储于NRF中。那么各NWDAF在需要采集位于其他NWDAF服务区域的网络功能的网络数据时，可以先向NRF发送查询请求，请求NRF反馈所需采集数据的网络功能归属的NWDAF的信息。
以源NWDAF为发送查询请求消息的NWDAF，请求查询的至少一个网络功能位于目标NWDAF的服务区域为例，其中，查询请求消息包括NWDAF选择辅助信息，NWDAF选择辅助信息包括至少一个网络功能的归属信息，那么NRF接收到查询请求消息后，可以根据至少一个网络功能的归属信息确定至少一个网络功能位于哪个目标NWDAF的服务区域。
NWDAF选择辅助信息是用于辅助选择至少一个网络功能所属NWDAF的 相关信息，包括至少一个网络功能的归属信息。NWDAF选择辅助信息还可以包括NWDAF的网络功能类型。NWDAF选择辅助信息包括以下信息中的至少一种：网络功能的切片信息、网络功能的标识、网络功能的位置信息。其中，网络功能的切片信息表示网络功能归属的切片信息，例如：通过NWDAF服务的切片信息和网络功能归属的切片信息，可以判断网络功能是否在该NWDAF服务区域内；网络功能的标识，表示各种网络功能信息，例如网络功能标识或AF标识或OAM标识等；网络功能的位置信息，表示网络功能的地理位置、跟踪区域、IP地址、小区、运营商信息、厂商信息等有效区分服务区域的信息。
NRF在接收到源NWDAF发送的查询请求消息后，将根据NWDAF选择辅助信息查询至少一个网络功能所属NWDAF的信息，即目标NWDAF的信息。例如NRF根据查询请求消息的网络功能的标识查询到服务于该网络功能标识的NWDAF；或者根据网络功能的切片信息或位置信息查询到服务于该切片或该位置的NWDAF，然后根据它们之间的关联关系确定服务于至网络功能的NWDAF。随后源NWDAF将接收到NRF发送的查询响应消息，查询响应消息包括目标NWDAF的信息。目标NWDAF的信息例如包括目标NWDAF标识和/或目标NWDAF的能力信息等。
在查询到目标NWDAF的信息后，源NWDAF即可向目标NWDAF发送网络功能数据采集请求，并接收目标NWDAF发送的网络功能数据采集响应，从而采集到网络功能反馈的网络数据。
在一实施例中，所述查询响应消息包括多个目标NWDAF的信息，所述至少一个网络功能分别位于所述多个目标NWDAF服务区域内。

步骤S910，NWDAF消费者向NWDAF1发送业务分析请求或订阅消息。
本实施例为NWDAF跨服务区域数据采集分析的方法。首先需要预配置如下信息：NWDAF消费者知道为其服务的NWDAF业务分析网络功能为NWDAF1。NWDAF1、NWDAF2已经注册到NRF中，如图7实施例所示。NWDAF1、NWDAF2可以归属于同一个PLMN，也可以是不同的PLMN。本实施例中，假设网络功能X归属于NWDAF2的服务区域，不归属于NWDAF1服务区域。本实施例的网络功能X表示3GPP网络功能NF、AF、OAM等。
NWDAF消费者发送业务分析请求和/或订阅消息给NWDAF1，消息至少包括以下参数组合：业务类型，分析目标关联信息，分析结果通知对象等。分析目标关联信息是用来确定分析业务类型所需采集数据的网络功能的辅助信息，例如：位置信息或网络功能标识或UE标识或AF标识或切片信息或其他可以用于辅助确定分析目标的关联信息。
步骤S920，NWDAF1确定需要采集数据的网元X。
NWDAF1收到的业务分析消息，确定本次业务分析请求需要到哪些网络功能采集数据进行业务分析。例如，NWDAF1可以根据分析业务类型确定需要采集数据的网络功能类型，根据分析目标关联信息到UDM或NRF或BSF或AMF或NEF确定需要采集数据的网络功能；本实施例假设确定的网络功能为网络功 能X。
步骤S930，NWDAF1判断是否可以直接到网元X采集数据。

本实施例为UE漫游状态下的通信状况分析的方法。本实施例中，假设某个UE注册在网络运营商PLMN 2中，漫游到PLMN 1。V-SMF(visit SMF)、V-NWDAF(visit NWDAF)、V-NRF(visit NRF)表示拜访地PLMN 1的网络功能；H-NWDAF(home NWDAF)、H-SMF(home SMF)表示归属地PLMN2的网络功能；AF是关联UE的应用功能；本实施例描述一种分析UE通信状况的流程。NWDAF消费者可以是网络中某个网络功能3GPP NF、AF、OAM。
NWDAF消费者发送消息请求分析UE的通信状况。消息可以是Nnwdaf_AnalyticsSubscription_Subscribe或Nnwdaf_AnalyticsInfo_Request消息；消息携带：业务分析类型(UE通信状况类型)，分析目标关联信息(UE相关标识)等信息。
步骤S1020，H-NWDAF确定需要分析UE通信状态需要采集数据的网元。
H-NWDAF网络功能收到请求，确定分析UE通信状况需要到AF、SMF网 络功能上采集数据，NWDAF发送查询消息到UDM或NEF上查询与UE关联的AF网络功能和SMF网络功能；NWDAF收到查询结果反馈的与UE关联的网络功能AF标识、V-SMF标识、H-SMF标识。
H-NWDAF判断需要采集数据的网元功能AF、V-SMF、H-SMF是否在它的服务区域内。本实施例AF、H-SMF在H-NWDAF服务区域内，直接通过步骤1030、1040进行数据采集；而V-SMF不在H-NWDAF服务区域内，执行步骤1050。
步骤S1030，H-NWDAF到UE关联的AF采集数据。
H-NWDAF网络功能到UE关联的AF请求采集数据：例如上下行数据速率等信息。
步骤S1040，H-NWDAF到UE关联的SMF采集数据。
H-NWDAF网络功能到UE关联的H-SMF上请求采集数据：例如与UE关联的会话信息。
步骤S1050，H-NWDAF查询V-SMF归属的NWDAF。
