本申请实施方式提供的网络辅助信息提供方法，目标用户终端发送第一请求消息，并在该第一请求消息中携带目标协议数据单元会话标识和非结构化请求数据，该非结构化请求数据包括携带目标分析标识的用户终端分析请求预测信元，从而可以实现将该非结构化请求数据传输至该目标协议数据单元会话标识对应的目标应用功能，进而该目标应用功能可以将该用户终端分析请求预测信元传输至目标网络数据分析功能，使得目标网络数据分析功能可以响应于该用户终端分析请求预测信元预测生成网络辅助信息，从而该目标用户终端可以通过接收包括目标协议数据单元会话标识和非结构化响应数据的第一通知消息，来获得包括该网络辅助信息和目标分析标识的用户终端分析响应信元，即实现了将网络辅助信息传输给了目标UE，可以用于改善目标UE的流媒体会话的QoE。
需要说明的是，本申请实施例提供的方法不限于适用于上行的流媒体，也可以适用于下行的流媒体。在下面的实施例中，均以上行流媒体举例说明。
图4示意性示出了本申请实施例所应用的FLUS框架图。
如图4所示的上行流媒体服务架构包括位于UE(以下称之为目标UE)侧的FLUS source(FLUS源)，以及位于另一UE或是网络(network)的FLUS sink(FLUS接收器)。FLUS source从一个或是多个捕获设备(Capture devices)中获得媒体内容(media content)，这些捕获设备可以是UE的组成部分，也可以是连接到UE的设备。FLUS sink可以位于另一UE，也可以位于网络。
在FLUS架构中定义了上行网络辅助功能，即Uplink Network Assistance(UNA)。该上行网络辅助功能使得FLUS source可以改善上行流媒体会话的QoE(Quality of Experience，体验质量)，该上行网络辅助功能是由Network Assistance Server(NAssS，网络辅助服务器)提供。NAssS是通过和上行流媒体不同的传输路径来提供网络辅助信息的。UNA的通信不依赖于F-U(Media Source and Sink，媒体源和接收器)和F-C(Control Source and Sink，控制源和接收器)的通信路径，因此，UNA的通信是发生在和FLUS流媒体完全不同的路径上。FLUS sink也不需要感知有UNA功能。UNA是基于FLUS source请求网络辅助信息来提供响应消息给FLUS source的。UNA功能可以提供给FLUS source如下任意一种或是两种信息：
-功能一：NAssS指示FLUS source在后面的时间段内最合适的上行流媒体传输速率。
-功能二：NAssS指示FLUS source临时的delivery boost function(传输提高功能)，用于解决当上行传输内容可能会超出输出缓存区的风险。
当上行网络辅助会话被激活时，client(本申请实施例中是指目标UE中的一个功能组件，是专门用于流媒体处理的客户端)会在发送下一段上行流媒体内容给FLUS sink前，发出上行网络辅助信息请求。上行网络辅助信息请求包含单一的逻辑信令交互。该交互或者激活了上述的第一个功能，或者是同时激活了上述两个功能。第二个功能只有在FLUS source授权接入到delivery boost function时才使用。如果client不需要传输提高，NassS会在响应给FLUS source的消息中删除第二个功能。
在本申请实施例中，NAssS是由网络中的AF来实现的，提供上行传输速率或者传输提高功能给FLUS source。
但是在目前相关标准中，并没有定义FLUS source和AF的交互流程，即AF如何把该上行网络辅助信息发送给FLUS source。
在本申请实施例中，NWDAF可以通过功能分析得到过去一段时间的业务体验数据/业务数据信息，也可以分析得到未来某个时间段的业务体验数据/业务数据信息。
本申请实施例中，NWDAF可以获得的业务体验数据/业务数据信息包含以下中的至少一项：某一个QoS业务流(称之为目标业务流)的数据传输速率预测值，某 一个QoS流的上行或下行的数据包延时预测值等。
本申请实施例中，NWDAF预测的某一个QoS流的数据传输速率预测值，是指该QoS流的数据传输速率在未来某个时间段的预测值，可以用于辅助FLUS source设置上行的流媒体传输速率；NWDAF预测的某一个QoS流的数据包延时预测值，是指该QoS流的数据包延时在未来某个时间段的预测值，可以用于对流媒体的相关参数进行调整，比如用于辅助FLUS source设置合适的buffer值(用于指示待发送流媒体的输出缓冲区的大小)，或者调整编码算法来匹配网络的状态等。因此，本申请实施例提出把NWDAF预测的业务数据信息(包括上行的数据传输速率预测值和/或数据包延时预测值)发送给FLUS source。
具体的，FLUS source可以直接将接收到的该QoS流的数据传输速率预测值，设置为其在后面的时间段内待发送流媒体的流媒体传输速率，也可以利用接收到的该QoS流的数据传输速率预测值，辅助设置其在后面的时间段内待发送流媒体的流媒体传输速率，本申请对此不做限定。
可以理解的是，若本申请实施例提供的方法适用于下行流媒体，则目标UE可以为FLUS sink所在的另一UE，且此时FLUS sink可以直接将接收到的该QoS流的数据传输速率预测值设置为其在后面的时间段内的待接收流媒体的流媒体传输速率，也可以利用接收到的该QoS流的数据传输速率预测值来辅助设置其在后面的时间段内的待接收流媒体的流媒体传输速率，本申请对此不做限定。
本申请实施例中，当接收到的QoS流的数据包延时预测值较大时，说明此时网络处于不太好的状态，可以对流媒体的相关参数进行调整，比如设置较大一些的buffer值，用于缓冲待发送流媒体，以防止网络状态不好导致的数据丢包；当接收到的QoS流的数据包延时预测值较小时，说明此时网络状态较好，则可以设置较小一些的buffer值，用于缓存待发送流媒体。
本申请实施例中，目标UE中可以针对待发送流媒体预先配置多种可选的编码算法(具体编码算法的类型和数量等均可以根据实际应用场景进行设置，本申请对此不作限定)或者，为编码算法配置不同的参数值。当接收到的QoS流的数据包延时预测值较大时，说明此时网络处于不太好的状态，可以对流媒体的相关设置或参数进行调整，比如选择编码复杂度小一些、编码性能低一些的编码算法作为待发送流媒体的目标编码算法，以匹配此时的网络状态；当接收到的QoS流的数据包延时预测值较小时，说明此时网络状态较好，可以对流媒体的相关设置或参数进行调整，比如选择编码复杂度大一些、编码性能高一些的编码算法作为待发送流媒体的目标编码算法，以匹配此时的网络状态。
本申请实施例中，NWDAF中的预测信息可以开放给AF。具体而言，目标UE可以触发建立到目标AF的控制面传输路径，将目标UE发送的数据分析预测请求(包括在非结构化请求数据中)发送给目标AF，目标AF可以根据目标UE的数据分析预测请求，从目标NWDAF中签约获得所需的预测信息(本申请实施例中为网络辅助信息)，当目标AF接收到目标NWDAF分析预测的网络辅助信息后，会将该网络 辅助信息通过控制面的传输路径发送给目标UE。

其中，Analytic ID为目标分析标识；Analytic sub-ID为目标分析子标识，是个可选参数；Target of Analytics Reporting为分析报告目的地址；UE ID为目标UE标识,Analytics Filter information为分析过滤器信息；IP filter information为IP过滤器信息，可以是指FLUS sink服务器地址信息，即待发送流媒体的目的地址信息，从而可以知道是针对哪个目标业务流，也可以用FQDN来代替，也可以同时有IP filter  information和FQDN，也可以包含PDU session ID(并包含QoS flow ID))；Area of Interest为感兴趣区域信息，即UE请求的是针对哪个区域的分析预测的网络辅助信息，是个可选参数；Analytics Reporting Information为分析报告信息。
通过该UE Analytic container，目标UE向目标AF发起其所需的数据分析预测请求。
本申请实施例中，分析报告信息可以包括分析报告信息参数，例如事件报告模式(Event Reporting mode)，可以设置报告的模式，如最大的分析报告次数(a maximum number of reports)、分析报告的周期性(periodic reporting along with periodicity)等等。
步骤1.2、AMF选择合适的SMF(称之为目标SMF)，并调用该目标SMF的服务建立PDU会话。
具体的，AMF向该目标SMF发送第二请求消息，该第二请求消息中可以包括SUPI(Subscription Permanent Identifier，订阅永久标识符，这里是指目标用户终端标识对应的目标用户终端的订阅永久标识符)，DNN，S-NSSAI,PDU session ID，AF ID，N1SM container(PDU Session Establishment Request)。
步骤1.3、目标SMF可以通过查询用户数据模块(UDM)或者NRF，得到为该AF ID，DNN,S-NSSAI服务的目标NEF(图中标记为NEF-1，第一网络开放功能)的信息。目标SMF调用该NEF-1的服务建立PDU会话。
具体的，目标SMF向NEF-1发送第三请求消息，该第三请求消息可以包括SUPI,User Identity(用户标识),PDU session ID,AF ID,S-NSSAI,DNN,Unstructured Data。
步骤1.4、NEF-1接收到该目标SMF的第三请求消息，当NEF-1和目标AF没有建立连接时，NEF-1会触发NIDD(Non-IP Data Delivery，非IP数据传送)，来配置流程建立NEF-1和目标AF的连接。
NEF-1会在NIDD配置请求中向目标AF发送参数GPSI(Generic Public Subscription Identifier，通用公共订阅标识符，这里是指目标UE外部ID，从SUPI转换得到),AF ID,NEF ID(这里是NEF-1标识)。
可选的，NEF-1可以在NIDD配置请求中发送Unstructured Data。如果NEF-1在NIDD配置请求中发送Unstructured Data，则不执行下述步骤1.5。
需要说明的是，图5实施例中，若NIDD配置流程预先已经完成，则也可以跳过步骤1.4。
步骤1.5、NEF-1向目标AF发送Unstructured Data。
步骤1.6、NEF-1向目标SMF发送PDU会话建立响应消息。目标SMF向AMF返回PDU会话建立响应消息。AMF向目标UE返回PDU会话建立响应消息。
除了图5所示的流程1之外，流程2为目标AF订阅并接收针对目标UE的包括网络辅助信息的通知消息，如图6所示，可以包括以下步骤。

UE Analytic container[Analytic ID,Analytic sub-ID，Target of Analytics Reporting＝UE ID,Analytics Filter information＝(IP filter information,Area of Interest),Analytics  Reporting Information]。
目标AF根据该目标UE的数据分析预测请求的内容，选择NEF-2(第二网络开放功能)作为流程2的目标NEF。本申请实施例中，目标AF与目标NWDAF的交互是独立于上述流程1的PDU会话建立流程的，因此，NEF-2可以选择与NEF-1相同的NEF，也可以选择不同的NEF，本申请对此不做限定。
步骤2.1、目标AF向NEF-2发送预测请求消息，该预测请求消息可以包括Analytic ID,Analytic sub-ID，Target of Analytics Reporting＝UE ID,Analytics Filter information＝(IP filter information,Area of Interest),Analytics Reporting Information。
如果目标AF可以直接和目标NWDAF连接，也可以直接将该预测请求消息发送给目标NWDAF,即跳过步骤2.2和2.3，直接执行步骤2.4。
步骤2.2、NEF-2接收到该预测请求消息后，确定合适的NWDAF作为目标NWDAF，并向该目标NWDAF发送该预测请求消息。
如果目标NWDAF接受该预测请求消息，则向NEF-2返回指示接受的响应消息。如果NWDAF拒绝预测请求消息，则返回指示拒绝的响应消息，并返回指示拒绝原因的值。
步骤2.3、NEF-2向目标AF返回响应消息，该响应消息包括目标NWDAF是否接受该预测请求消息。
步骤2.4、目标NWDAF会根据数据分析预测请求中的参数，确定哪些NF作为目标网元，并从目标网元中接收对应的数据信息作为目标数据，对该目标数据进行分析，得到在未来一段时间内该目标UE的由该IP filter information标识的目标业务流的分析预测结果，以作为网络辅助信息。并将分析预测结果通知给NEF-2，分析预测结果包含：Analytics ID,Analytic sub-ID，analytics information，以及预测结果的时间戳信息，预测结果的有效时间，预测结果的有效地点，预测置信度。
本申请实施例中，目标NWDAF根据用户终端分析请求预测信元对应的UE Analytic container，确定目标网元，例如可以根据UE Analytic container中的Analytic ID和Analytic sub-ID等确定PCF和/或UPF等作为目标网元。其中，NWDAF可以从任何NF收集数据。因此，NWDAF从PCF、UPF等目标网元获取目标数据，然后对获取的目标数据进行数据分析，得到满足要求的预测结果作为网络辅助信息。
NEF-2发送第二通知消息给目标AF，该第二通知消息包括UE Analytic container(这里对应的是用户终端分析响应信元)，所述用户终端分析响应信元包括网络辅助信息和所述目标分析标识，可选的包括Analytic sub-ID。
如果目标NWDAF与目标AF有直接连接，没有执行步骤2.2和2.3时，目标NWDAF也可以直接发送通知消息给目标AF。
步骤2.5、目标AF接收到NEF-2发送的第二通知消息后，生成非结构化响应数据，然后调用NEF-1的服务，发送非结构化响应数据给NEF-1。
具体的，目标AF向NEF-1发送第三通知消息，该第三通知消息中包含UE ID,AF ID,TLTRI(long-term interaction reference identification，长期交互参考标识),非 结构化响应数据。非结构化响应数据包含UE Analytic container[Analytics ID,Analytic sub-ID，analytics information，预测结果的时间戳信息，预测结果的有效时间，预测结果的有效地点，预测置信度]。
步骤2.6、NEF-1调用目标SMF的服务，发送非结构化响应数据给目标SMF。
具体的，NEF-1向目标SMF发送第四通知消息，该第四通知消息中包含UE ID，PDU session ID，非结构化响应数据。
步骤2.7、目标SMF将该第四通知消息发送给AMF。
步骤2.8、当目标UE处于连接态时，AMF向目标UE发送第一通知消息，该第一通知消息包含PDU session ID和非结构化响应数据。
如果该目标UE处于空闲态，则AMF先对该目标UE进行寻呼，当目标UE建立了与AMF的NAS(Non-access stratum，非接入层)连接之后，AMF将PDU session ID和非结构化响应数据发送给该目标UE。
本申请实施例中，网络辅助信息可以包括UE Analytic container中的analytics information，预测结果的时间戳信息，预测结果的有效时间，预测结果的有效地点，预测置信度。analytics information具体可以根据Analytics ID和Analytic sub-ID来确定，例如可以包括目标业务流标识对应的目标业务流的数据传输速率预测值和/或目标业务流的数据包延时预测值。
本申请实施例中，提供了以下三种可选的Analytics ID,Analytic sub-ID的设置方式：
参数可选设置方式一：
将上述步骤1.1中的Analytic ID＝UE Analytics(用户终端分析)，增加Analytic sub-ID＝Service experience(服务体验)，则上述步骤2.4中的analytics information具体可以包含目标QoS流的数据传输速率预测值、数据包延时预测值中的至少一个。
参数可选设置方式二：
将上述步骤1.1中的Analytic ID＝Service experience，增加Analytic sub-ID＝bitrate recommendation(比特率推荐)，或/和Analytic sub-ID＝latency(延时)，则上述步骤2.4中的analytics information包含Analytic sub-ID中请求的内容，即目标QoS流的数据传输速率预测值，或/和数据包延时预测值。
参数可选设置方式三：
将上述步骤1.1中的Analytic ID＝UE Analytics，增加Analytic sub-ID＝bitrate recommendation，或/和Analytic sub-ID＝latency，则上述步骤2.4中的analytics information包含Analytic sub-ID中请求的内容，即目标QoS流的数据传输速率预测值，或/和数据包延时预测值。
可以理解的是，Analytics ID和Analytic sub-ID的具体参数取值所代表的含义，可以根据协商来确定，并不限于上述例举的情况和所命名的名称。例如，也可以设置UE Analytic container中只包括Analytics ID，一旦目标NWDAF接收到UE Analytic container，则目标NWDAF即可知道是目标UE请求进行目标用户终端的数据分析 预测，此时，目标NWDAF可以将目标Analytics ID对应的预测好的目标QoS流的数据传输速率预测值，或/和数据包延时预测值，通过AMF返回至目标UE。
若UE Analytic container中同时包括Analytics ID和Analytic sub-ID，则根据Analytics ID和Analytic sub-ID的取值，将预测好的目标QoS流的数据传输速率预测值和/或数据包延时预测值返回至目标UE。
在图5实施例中UE在PDU会话建立流程中携带Unstructured Data，在图7实施例中，也可以在PDU会话建立后发送目标UE的数据分析预测请求。具体的业务流程图如图7所示。如图7所示，可以包括以下步骤。
步骤3.1、目标UE在已有的PDU会话上向目标SMF发送第一请求消息。
具体的，目标UE向目标SMF发送第一请求消息，该第一请求消息中携带PDU session ID以及非结构化数据(Unstructured Data，这里具体对应的是非结构化请求数据)。

步骤3.3、NEF-1将该第一请求消息中的内容发送给目标AF。
具体的，NEF-1向目标AF发送第五请求消息，该第五请求消息可以包括该目标UE的外部标识,PDU session ID,以及非结构化请求数据。
步骤3.4、目标AF依次通过NEF-1和SMF向目标UE发送第一通知消息。
具体的，目标AF向NEF-1发送第五通知消息，该第五通知消息中可以包括目标用户终端标识、PDU session ID和非结构化响应数据。
NEF-1接收到该第五通知消息后，可以向SMF发送第六通知消息，该第六通知消息可以包括目标用户终端标识、PDU session ID和非结构化响应数据。
SMF接收到该第五通知消息后，可以向目标UE发送第一通知消息，所述第一通知消息包括PDU session ID和非结构化响应数据。
本申请实施例提出了一种网络辅助信息提供方法，能够把NWDAF预测的业务信息数据(即网络辅助信息)发送给FLUS source。即提供了一种由AF作为NAssS，提供预测的业务信息数据给FLUS source的方法，并扩展了辅助信息的范围。即与传统技术相比，AF除了可以返回目标业务流标识对应的目标业务流的数据传输速率预测值(bitrate recommendation，比特率推荐)，还可以返回目标业务流的数据包延时预测值(latency)。目标UE接收到返回的网络辅助信息后，可以辅助进行流媒体传输速率的设置、输出/输入缓冲区大小的设置、编解码算法的匹配等优化处理。
