本申请要求在2018年02月14日提交中国国家知识产权局、申请号为201810154028.9、发明名称为“一种资源分配方法和装置”的中国专利申请以及在2018年05月22日提交中国国家知识产权局、申请号为201810497454.2、发明名称为“一种资源分配方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，尤其涉及一种资源分配方法和装置。
背景技术
目前，通信网络采用服务质量(Quality of Service，QoS)机制来为用户提供业务的服务质量保障，但当前的QoS机制中的QoS参数的设置通常不够合理或较为固定，导致QoS信息可能是不准确的或网元不适用的。例如，目前协议将丢包率、时延、错误率定义为标准服务质量指示(5QI)对应的三个重要QoS参数，但目前基站无法通过丢包率、时延、错误率判断业务的服务质量是否得到满足，从而无法保证业务的服务质量；又如，目前协议推荐将计算上述三个参数的平均窗口大小(average window size)定义为2s，但没有任何根据说明该值的设置是合理的，而实际上该值的设置应该是要根据网络部署场景或业务类型的不同来动态设置的。

202、数据分析网元生成业务的至少一条QoS描述信息。
至少一条QoS描述信息中的每条QoS描述信息可以包括QoS参数类型和/或QoS参 数要求。QoS参数类型和/或QoS参数要求可以隐式指示QoS参数类型和/或QoS参数要求对应的网元。
其中，每条QoS描述信息可以包含一个或多个QoS参数类型，QoS参数类型包括QoS参数的具体类型或名称，每个QoS参数可以对应一个参数类型或名称。每条QoS描述信息可以包含一个或多个QoS参数要求，QoS参数要求包括QoS参数的具体取值要求，具体取值要求的类型包括但不限于数值类型、日期类型、时间类型、布尔类型。需要说明的是，具体取值要求可以是参数的实际物理取值，也可以是参数取值进行归一化处理后的取值。归一化处理是指将参数的物理取值映射到固定取值空间的操作，例如采用最大最小值归一化方法、Z-Score归一化方法等将每个特征的物理数据值映射到固定的数值空间。这种处理一方面便于在大数据分析过程中提高模型训练收敛速度，另一方面提供了一种特征数据传输方式。示例性的，QoS参数要求集合包括协议已定义的以下至少一项QoS参数要求：服务质量分类识别码(QoS class identifier)要求、反射QoS属性(reflective QoS attribute，RQA)要求、分配与保持优先级(allocation/retension priority，ARP)要求、通知控制(notification control)要求、保证流比特率(guaranteed flow bit rate，GFBR)要求、最大流比特率(maximum flow bit rate，MFBR)要求、会话聚合最大比特速率(session-aggregate maximum bit rate，session-AMBR)要求、用户设备聚合最大比特速率(UE-aggregate maximum bit rate，UE-AMBR)要求、最大丢包率要求(maximun Packet Loss Rate，Max PLR)要求，资源类型(resource type)要求，数据包延迟预算(packet delay budget，PDB)要求、数据错误率(packet error rate，PER)要求、优先级要求、平均时间窗口(average window，AW)要求、最大数据突发量(maximum data burst volume)要求。说明一点，上述GFBR、MFBR、Max PLR等参数要求可用于指示上行或下行数据的GFBR、MFBR、Max PLR要求。在一种可能的实现方式中，QoS参数要求集合还可以包括目前标准未定义的QoS参数要求，例如包括以下至少一项：时间信息要求、位置信息要求、数据包大小要求、编码方式要求、抖动要求、数据包到达率要求、流量激活率要求、无线信道质量要求、用户标识/类型要求、用户IP五元组要求。其中，时间信息要求用于指示当前的QoS描述信息适用的时间；位置信息要求用于指示当前的QoS描述信息适用的位置。类似地，其他QoS参数要求用于指示当前QoS描述信息适用的场景。在一种可能的实现方式中，QoS参数要求集合还可以包括归一化的特征要求，其中，归一化的特征要求是通过将QoS参数要求的物理数值映射到固定的数值空间获取的。
在一种可能的实现方式中，至少一条QoS描述信息中的每条QoS描述信息可以对应一个QoS描述信息索引，例如数字编号，该数字编号可以用于指代对应的QoS描述信息。
举例来说，如表1所示，假设业务为IMS视频业务，数据分析网元对IMS视频业务的训练数据进行分析后，生成编号为0和1的2条QoS描述信息，每条QoS描述信息的QoS参数类型集合包括时间段、GBR、MBR、数据丢包率、时延和窗口大小，从而每条QoS描述信息的QoS参数要求集合包括时间段要求、GBR要求、MBR要求、数据丢包率要求、时延要求和窗口大小要求。
表1
数字编号 时间 GBR MBR 数据丢包率 时延 窗口大小
0 白天段(06：00-18:00) 496kbps 5120kbps 0.1％ 150ms 2s
1 夜晚段(18:00-06:00) 568kbps 8640kbps 0.1％ 100ms 2s
如表2所示，假设业务为VoLTE业务，数据分析网元对VoLTE业务的训练数据进行分析后，生成编号为0-5的6条QoS描述信息，每条QoS描述信息的QoS参数类型集合包括上行/下行(Uplink/Downlink，UL/DL)Max PLR，编码类型和编码速率，从而每条QoS描述信息的QoS参数要求集合包括UL/DL Max PLR要求，编码类型要求和编码速率要求。
表2
数字编号 编码类型 编码速率(kbps) UL/DL Max PLR
0 AMR-WB 6.6 1％
1 AMR-WB 12.65 3％
2 AMR-WB 23.85 4％
3 EVS 5.9 3％
4 EVS 64 5％
5 EVS 128 6％
在一种可能的实现方式中，至少一条QoS描述信息中的每条QoS描述信息还包括网元信息。网元信息包括一个或多个网元信息，每个网元信息用于指示QoS参数要求中的至少一个QoS参数要求对应的网元。其中，网元信息可以包括网元类型信息或标识信息。网元信息用于指示对应的QoS参数要求可以应用的一个或一类网元。例如，丢包率要求和平均窗口大小要求应用于UPF，即UPF可以根据网元信息中的UPF信息(UPF标识或类型)确定每条QoS描述信息中与自身相关的QoS参数要求包括丢包率要求和平均窗口大小要求，后续UPF只需判断当前网络(包括自身)的丢包率和平均窗口大小是否能是否能满足每条QoS描述信息中的丢包率要求和平均窗口大小要求，UPF不必识别或考虑QoS描述信息中的其他QoS参数要求。从而，UPF可以从接收到的至少一条QoS描述信息中筛选出0条、1条或多条丢包率要求和平均窗口大小要求能被满足的QoS描述信息，过滤掉其他丢包率要求和平均窗口大小要求不能被满足的QoS描述信息；又如，时间要求应用于PCF，即PCF可以根据网元信息中的PCF信息确定每条QoS描述信息中与自身相关的QoS参数要求包括时间要求，后续PCF只需判断当前网络的时间是否能每条QoS描述信息中的时间要求，据此PCF可以从接收的至少一条QoS描述信息中选择出0条、1条或多条时间要求能被满足的QoS描述信息，过滤掉其他时间要求不能被满足的QoS描述信息。需要说明的是，网元信息可以是指QoS参数要求将被某个网元应用或判断，例如上述时间要求的网元信息为PCF，其具体含义是将有PCF来判断或应用时间要求；又如，假设位置要求可能被作为某QoS描述信息中的一个QoS参数要求，且假设这个位置要求对应的网元为接入网设备，则具体的含义是将由接入网设备来判断或使用该位置要求，例如，判断执行业务的用户终端的位置是否符合该位置要求，而位置要求本身可以不是对接入网本身的属性要求。在一种可能的实现方式中，QoS描述信息中的网元信息不必覆盖每个QoS参数要求，即存在一个或多个QoS参数要 求未指明对应网元的情况，例如，假设Max PLR作为某业务的QoS描述信息中的一个QoS参数要求，而协议已明确定义Max PLR是给接入网网元的参数，则该QoS描述信息中可不必存在Max PLR参数对应的网元信息。
示例性的，数据分析网元可以基于业务服务器提供的业务数据(如业务体验)，使用现有的大数据学习分析方法，获取业务的至少一条QoS描述信息。例如，假设业务为URLLC业务，采用平均意见分(Mean Opinion Score，MOS)来描述URLLC业务的业务体验，MOS的范围为[0，5]，数值越大，URLLC业务的业务体验越好。如表3所示，数据分析网元对URLLC业务的训练数据进行分析后，可以得出影响URLLC业务的MOS的QoS参数类型集合包括上下行数据传输的最大丢包率(Max Packet Loss Rate，Max PLR)、数据包到达率(Packet Arrival Rate)和数据包大小(Packet Size)，从而得出QoS参数要求集合包括Max PLR数值要求、Packet Arrival Rate数值要求和Packet Size数值要求，并得出网元信息集合包括Max PLR、Packet Arrival Rate和Packet Size分别对应的网元信息，例如Max PLR可以对应接入网网元、Packet Arrival Rate可以对应核心网网元(PCF/SMF/AMF/UPF)，Packet Size可以对应终端设备。即网元信息集合包括核心网网元、接入网网元和终端设备。

如表4所示，假设业务为V2X业务，采用MOS来描述V2X业务的业务体验。数据分析网元对V2X业务的训练数据进行分析后，可以得出影响V2X业务的MOS的QoS参数类型集合包括平均窗口、数据包丢包率、该业务用户所在小区的RSRP、该业务媒体面数据编码类型、编码速率和该业务所在时间段，从而得出QoS参数要求集合包括接收窗口要求、数据包丢包率要求、该业务用户所在小区的RSRP要求(归一化的值，且在[0，1]区间内)、该业务媒体面数据编码方式要求和该业务所在时间段要求，并得出网元信息集合包括平均窗口、数据包丢包率、该业务用户所在小区的RSRP、该业务媒体面数据编码方式和该业务所在时间段分别对应的网元信息，例如该业务媒体面数据编码方式要求和该业务所在时间段要求对应PCF，数据包丢包率和平均窗口要求对应UPF，该业务用户所在小区的RSRP要求可以对应AN。即网元信息包括PCF，UPF和AN。

在一种可能的实现方式中，至少一条QoS描述信息中的每条QoS描述信息可以对应 网络网元或终端设备或业务服务器中的一个QoS策略，例如，网络网元、终端设备或业务服务器可以将接收到的QoS描述信息本身作为QoS策略，也可以根据QoS描述信息生成或映射出对应的QoS策略。网络网元、终端设备或业务服务器可以执行相应QoS策略，例如根据QoS策略要求分配相应的资源和/或执行相应的门限控制等。
本申请实施例，数据分析网元向第一核心网网元(核心网网元)发送至少一条QoS描述信息的方法中，第一核心网网元可以是策略控制功能网元、会话管理功能网元、用户面功能网元、接入控制功能网元、接入网功能网元中的至少一个，此处不做限定。数据分析网元可以经过点对点接口向第一核心网网元发送至少一条QoS描述信息，也可以经服务化接口向第一核心网网元发送至少一条QoS描述信息，此处也不作限定。
203、数据分析网元向核心网网元发送至少一条QoS描述信息。
在一种可能的实现方式中，数据分析网元向核心网网元发送至少一条QoS描述信息之前，数据分析网元接收核心网网元发送业务的QoS描述信息请求消息。QoS描述信息请求消息用于请求业务的至少一条QoS描述信息，QoS描述信息请求消息包括业务的业务标识信息(例如，公共陆地移动网络(public land mobile network，PLMN)ID、业务标识(service ID)和分析标识(analytic ID))。
在一种可能的实现方式中，QoS描述信息请求消息中还可以包括执行该业务的终端设备的标识信息(IMSI、SUPI或UE IP地址)，终端设备的位置信息(当前终端所处TA或TA列表或小区列表(cell list))和终端设备所在的数据网络的名称等。在一种可能的设计中，核心网网元向数据分析网元发送业务的QoS描述信息请求消息之前，在业务的建立过程中，核心网网元接收该业务的业务服务器发送的认证授权请求消息(例如策略认证授权请求消息)，认证授权请求消息包括业务标识信息，用于指示建立业务标识信息对应的业务。其中，业务的标识信息可以是由数据分析网元提前统一为任一类业务分配并发送给对应的业务服务器的。数据分析网元可以通过NEF与业务服务器通信，数据分析网元、NEF和业务服务器之间可以通过统一的北向接口通信。具体的，业务服务器可以通过统一的北向接口向数据分析网元请求业务标识信息分配，或业务服务器经统一的北向接口向NEF请求业务标识信息分配，再由NEF向数据分析网元请求业务标识信息分配。业务标识信息也可以是其他网元向PCF提供的，例如在业务对应的会话建立过程中，由SMF或终端设备向PCF提供的业务标识信息，此处并不限定。其中，业务标识信息可以是业务类型信息。
在一种可能的实现方式中，认证授权请求消息还可以包括业务的其他应用层信息，例如分类器标识、带宽要求描述信息、媒体类型描述信息和媒体编码方式等。
在一种可能的实现方式中，认证授权请求消息中还可以包括指示信息(第五指示信息)，用于指示网络网元(包括PCF、SMF、AMF、UPF、AN、UE)在确定不满足业务的服务质量要求时，向业务服务器发送第四指示信息，第四指示信息可以包括各网元不满足业务的服务质量要求和/或不满足的具体Qos参数要求。需要说明的是，不满足业务的服务质量要求时具体可以是指不满足网络网元接收到的至少一条Qos描述信息中的任何一条Qos描述信息。网络网元不满足一条Qos描述信息可以是网络网元对应的参数不满足该Qos描述信息中的一个或多个Qos参数要求。
在一种可能的实现方式中，若数据分析网元接收核心网网元发送业务的QoS描述 信息请求消息，数据分析网元可以向核心网网元发送Qos描述信息响应消息，Qos描述信息响应消息中包括至少一条Qos描述信息。至少一条Qos描述信息可以通过表格、图像、函数或描述文件等形式呈现，本申请不做限定。
在一种可能的设计中，数据分析网元根据训练数据获取业务的至少一条QoS描述信息之后，可向PCF主动推送业务的至少一条QoS描述信息，即核心网网元无需向数据分析网元请求QoS描述信息。且推送过程中数据分析网元还可同时向PCF发送至少一条QoS描述信息对应的业务的业务标识信息。在一种可能的实现方式中，数据分析网元可选择主动推送的时机，可实时推送，也可离线推送；可单业务推送，也可多业务批量推送。
在数据分析网元主动向PCF推送至少一条QoS描述信息的场景下，PCF可以接收业务服务器发送的认证授权请求消息或会话管理功能网元发送的业务相关会话策略控制请求消息，认证授权请求消息或会话策略控制请求消息用于请求建立业务相关专有隧道或业务相关会话的。在一种可能的实现方式中，认证授权请求消息包含业务标识信息和其他应用层信息，例如分类器标识、带宽要求描述信息、媒体类型描述信息和媒体编码方式等。在一种可能的实现方式中，认证授权请求消息中还可以包含第五指示信息，第五指示用于指示网络网元在确定不满足业务的服务质量要求时，向业务服务器发送第四指示信息，第四指示信息用于指示不满足业务的服务质量要求和/或不满足的具体QoS参数要求。会话策略控制请求消息中包含业务标识信息和其他网络参数，例如用户位置信息、用户类型信息等。
在一种可能的实现中，数据分析网元向核心网网元发送至少一条QoS描述信息时，需要考虑用户的标识信息或位置信息等，例如，根据用户当前所在的TA或TA列表或cell list列表，数据分析网元筛选符合当前位置场景的至少一条QoS描述信息，并下发给核心网网元，无需将生成的业务的所有的QoS描述信息下发；又如，根据执行业务的用户终端类型，下发符合当前终端类型场景的至少一条QoS描述信息。
在一种可能的实现方式中，数据分析网元在向核心网网元发送至少一条QoS描述信息的同时，还可以向核心网网元发送第五指示信息，或通过核心网网元向其他网络网元发送第五指示信息，第五指示用于指示网络网元在确定不满足业务的服务质量要求时，向数据分析网元发送第四指示信息，第四指示信息用于指示相应的网元不满足业务的服务质量要求和/或不满足的具体QoS参数要求，这里，不满足业务的服务质量要求即指不满足任何一条QoS描述信息的QoS参数要求。如此，可以加强网络向数据分析网元反馈QoS描述信息的准确性和有效性，以便于数据分析网元自适应调整QoS描述信息生成方法，从而获取更加精准的业务QoS描述信息。
另外，若QoS描述信息中不包括网元信息集合时，数据分析网元还可以在发送至少一条QoS描述信息同时向核心网网元发送网元信息集合。例如，在同一条消息中向核心网网元发送至少一条QoS描述信息和网元信息集合。
204、第一核心网网元接收数据分析网元或第二核心网网元或业务服务器发送的业务的至少一条QoS描述信息。
其中，第一核心网网元包括PCF、SMF、UPF和AMF中的一个。
需要说明的是，当第一核心网网元为PCF时，PCF接收数据分析网元或业务服务器 发送的业务的至少一条QoS描述信息。在一种可能的设计中，PCF接收数据分析网元发送的业务的至少一条QoS描述信息之后，PCF可以将PCF接收到的至少一条QoS描述信息的部分或全部QoS描述信息发送给业务服务器。业务服务器可以将业务服务器接收到的至少一条QoS描述信息的部分或全部QoS描述信息反馈给PCF。
当第一核心网网元为SMF，第二核心网网元为PCF时，SMF接收PCF或数据分析网元发送的业务的至少一条QoS描述信息。其中，PCF发送的至少一条QoS描述信息包括数据分析网元生成的至少一条QoS描述信息的部分或全部QoS描述信息。
当第一核心网网元为UPF或AMF，第二核心网网元为SMF时，UPF或AMF接收SMF或数据分析网元发送的业务的至少一条QoS描述信息。其中，SMF发送的至少一条QoS描述信息包括SMF接收到的至少一条QoS描述信息的部分或全部QoS描述信息。
205、第一核心网网元确定QoS描述信息的集合(第三集合)，该集合包括至少一条QoS描述信息的部分或者全部QoS描述信息。
对于第一核心网网元接收到的至少一条QoS描述信息中的每条QoS描述信息，第一核心网网元可以根据网元信息确定该条QoS描述信息中第一核心网网元对应的一个或多个QoS参数类型，并根据第一核心网网元对应的一个或多个QoS参数类型确定第一核心网网元对应的一个或多个QoS参数要求。而后，第一核心网网元根据自身相关QoS参数要求确定每条QoS描述信息是否能被第一核心网网元满足。其中，能被满足的QoS描述信息组成了第一核心网网元满足的QoS描述信息集合，该集合可包含0条、1条或多条QoS描述信息。需要说明的是，第一核心网网元满足一条或多条QoS描述信息并不限于第一核心网网元自身属性条件能满足该一条或多条QoS描述信息中的相关QoS参数要求，还可以包括与第一核心网网元相关的参数(例如时间，业务编码方式)能满足该QoS描述信息中相应的QoS参数要求，即这些参数要求可以不是对第一核心网网元自身属性的要求，而是由第一核心网网元来判断和使用的。类似地，本申请后续步骤中出现的的其他网元满足QoS描述信息也是同样的含义可以参考第一核心网网元满足一条或多条QoS描述信息的说明。
在一种可能的设计中，若QoS描述信息中不含有网元信息，或数据分析网元未下发网元信息集合的情况下，第一核心网网元可以根据自身能力识别QoS描述信息中与自身相关的QoS参数要求，并根据自身相关的QoS参数要求确定第一核心网网元满足的QoS描述信息集合。具体的，对于第一核心网网元从数据分析网元接收到的至少一条QoS描述信息中的每条QoS描述信息，第一核心网网元可以识别出QoS描述信息中与自身相关的QoS参数要求。而后，第一核心网网元根据自身相关QoS参数要求确定每条QoS描述信息是否能被第一核心网网元满足，其中，能被满足的QoS描述信息组成了第一核心网网元满足的QoS描述信息集合，该集合可包含0条、1条或多条QoS描述信息。
在本申请的另一种设计中，当第一核心网网元确定第一核心网网元接收到的至少一条QoS描述信息中没有与自身相关的QoS参数要求时，第一核心网网元满足的QoS描述信息的集合包括至少一条QoS描述信息的全部QoS描述信息，即第一核心网网元无需进行筛选操作(即确定QoS描述信息的第三集合)，仅需进行向第二核心网网元或接入网网元转发至少一条QoS描述信息的操作。第一核心网网元可以通过网元信息和/或QoS参数要求确定其所接收到的至少一条QoS描述信息中是否有与自身相关的QoS参 数要求。在一种可能的设计中，当第一核心网网元为SMF、AMF或UPF时，若SMF、AMF或UPF确定其所接收到的至少一条QoS描述信息没有与自身相关的QoS参数要求时，SMF、AMF或UPF无需进行筛选操作，仅需进行向下一个网元转发至少一条QoS描述信息的操作。
在一种可能的设计中，当第一核心网网元为PCF时，QoS描述信息的第三集合即PCF满足的QoS描述信息的集合，PCF满足的QoS描述信息的集合包括业务的至少一条QoS描述信息的部分或全部QoS描述信息。
举例来说，如表5所示，假设PCF接收到NWDA发送的语音业务的10条QoS描述信息，每条QoS描述信息可以分别对应数字编号0-9。每条QoS描述信息中的网元信息集合可以包括PCF、AN和UE。PCF对应的QoS参数类型集合包括时间信息、业务编码类型和业务编码速率；AN对应的参数类型集合可以包括数据丢包率、时延、开始时间和结束时间，UE对应的参数类型集合可以包括UE优先级信息和UE类型。相应的，PCF对应的QoS参数要求包括时间信息要求、业务编码类型要求和业务编码速率要求；AN对应的参数类型集合可以包括数据丢包率要求、时延要求、开始时间要求和结束时间要求，UE对应的参数类型集合可以包括UE优先级信息要求和UE类型要求。
表5

Figure PCTCN2019074809-appb-000004
PCF可以确定每条QoS描述信息中与自身相关的QoS参数要求是时间要求、业务编码类型要求和业务编码速率要求，而后，PCF确定当前的时间属于白天段，业务当前实际使用的编码类型为AMR-WB，且业务当前的编码速率属于5-50(Kbps)区间范围，从而确定数字编号为0-7的8条QoS描述信息为PCF满足的QoS描述信息集合。可以理解的是，当前的时间可以为属于白天段的任意一个时刻。
当第一核心网网元为SMF时，QoS描述信息的第三集合即SMF满足的QoS描述信息的集合，SMF满足的QoS描述信息的集合包括业务的至少一条QoS描述信息的部分或全部QoS描述信息。在一种可能的设计中，SMF满足的QoS描述信息的集合是PCF满足的QoS描述信息的集合的子集。
当第一核心网网元为UPF或AMF时，QoS描述信息的第三集合即UPF或AMF满足的QoS描述信息的集合，UPF或AMF满足的QoS描述信息的集合包括业务的至少一条QoS描述信息的部分或全部QoS描述信息。在一种可能的设计中，UPF或AMF满足的QoS描述信息的集合是SMF满足的QoS描述信息的集合的子集。
206、在一种可能的设计中，当第一核心网网元不满足业务的服务质量要求时，第一核心网网元向业务的业务服务器发送指示信息(第四指示信息)，用于指示第一核心网网元不满足业务的服务质量要求和/或不满足的具体Qos参数要求。
第一核心网网元不满足业务的服务质量要求，可以是第一核心网网元对应的参数信息不满足至少一条QoS描述信息中的任何一条QoS描述信息中的QoS参数要求，即第一核心网网元无法确定第一核心网网元满足的QoS描述信息集合。举例来说，第一核心网网元设置第四指示信息的方法可以是：当第一核心网网元确定当前业务实际使用的编码方式不满足任一条QoS描述信息中的编码方式要求时，第一核心网网元将第四指示信息具体设置为当前编码方式不符合相应的Qos参数要求。由此业务服务器可以获知业务建立失败的具体原因，并可以进一步地调整相应的应用层策略，例如转换业务编码方式。又如，当第一核心网网元确定当前时间和当前业务实际使用的编码方式不符合任一条QoS描述信息中时间要求和编码方式要求的组合时，第四指示信息可以具体指示当前时间下业务实际使用的编码方式不符合相应的Qos参数要求。上述只是举例说明，实际还存在第一核心网网元因其他原因而不能满足任一条QoS描述信息的场景，此处不做限制。可以理解的是，下文中其他网元设置第四指示信息可以参考第一核心网网元设置第四指示信息的方法。
在一种可能的实现方式中，当确定第一核心网网元对应的参数集合不满足至少一条QoS描述信息中的任何一条QoS描述信息中的QoS参数要求集合时，即第一核心网网元无法确定第一核心网网元满足的QoS描述信息集合时，第一核心网网元可以向第二 核心网网元或数据分析网元发送指示信息(第四指示信息)，用于指示相应的网元不满足业务的服务质量要求和/或不满足的具体QoS参数要求。第二核心网网元或数据分析网元也可以根据接收到的第四指示信息采取相应的调整策略。在一种可能的实现方式中，第二核心网网元根据第四指示信息重新对自身接收到QoS描述信息进行筛选后发给第一核心网网元。例如，SMF接收AMF或AN或UPF反馈的第四指示信息之后，SMF请求PCF更新可选的QoS描述信息，并可携带具体的原因值；或SMF自身根据第四指示重新从接收至少一条QoS描述信息中筛选出符合要求的一个或多个QoS描述信息。在另一种可能的实现方式中数据分析网元根据第四指示信息可重新训练业务的QoS描述信息。
在一种可能的实现方式中，第一核心网网元接收数据分析网元发送的指示信息(第五指示信息)，用于指示网络网元在确定不满足业务的服务质量要求时，向PCF发送第四指示信息。若第一核心网网元接收到数据分析网元发送的第五指示信息，那么本步骤中，第一核心网网元根据第五指示信息向数据分析网元发送第四指示信息。
207、第一核心网网元向第三核心网网元或接入网网元发送QoS描述信息的第三集合。
第一核心网网元为PCF时，第三核心网网元可以为SMF，第三集合为PCF满足的QoS描述信息的集合，即PCF向SMF发送PCF满足的QoS描述信息的集合。其中，PCF满足的QoS描述信息的集合包括PCF接收到的至少一条QoS描述信息的部分或全部QoS描述信息。
第一核心网网元为SMF时，第三核心网网元可以为UPF或AMF，第三集合为SMF满足的QoS描述信息的集合，即SMF向UPF或AMF发送SMF满足的QoS描述信息的集合。其中，SMF满足的QoS描述信息的集合包括SMF接收到的至少一条QoS描述信息的部分或全部QoS描述信息。
第一核心网网元为AMF时，第三集合为AMF满足的QoS描述信息的集合，即AMF向接入网网元发送AMF满足的QoS描述信息的集合。其中，AMF满足的QoS描述信息的集合包括AMF接收到的至少一条QoS描述信息的部分或全部QoS描述信息。
在一种可能的实现方式中，当第一核心网网元从第二核心网网元或数据分析网元或业务服务器获取至少一条QoS描述信息的同时，还获取到了网元信息，则第一核心网网元向第三核心网网元或接入网网元发送QoS描述信息的第三集合的同时，还需将网元信息发送给第三核心网网元或接入网网元。
在一种可能的实现方式中，当第一核心网网元获取了第五指示信息，则第一核心网网元向第三核心网网元或接入网网元发送QoS描述信息的第三集合的同时，还需将第五指示信息发送给第三核心网网元或接入网网元。
208、接入网网元接收核心网网元发送的业务的至少一条QoS描述信息。
在一种可能的实现方式中，核心网网元为AMF网元。接入网网元接收AMF发送的业务的至少一条QoS描述信息。其中，AMF发送的业务的至少一条QoS描述信息可以是AMF满足的QoS描述信息的集合。
在一种可能的实现方式中，当核心网网元为PCF时，接入网网元可以通过SMF和AMF接收PCF发送的业务的至少一条QoS描述信息。其中，PCF发送的业务的至少一条 QoS描述信息可以是PCF满足的QoS描述信息的集合。
在一种可能的实现方式中，当核心网网元为SMF时，接入网网元可以通过AMF接收SMF发送的业务的至少一条QoS描述信息。其中，SMF发送的业务的至少一条QoS描述信息可以是SMF满足的QoS描述信息的集合。
在一种可能的实现方式中，接入网网元还接收核心网网元发送的网元信息和/或第五指示信息。
209、接入网网元从至少一条QoS描述信息中确定业务的一条目标QoS描述信息。
在一种可能的设计中，接入网网元从接入网网元接收到的至少一条QoS描述信息中确定业务的一条目标QoS描述信息。
示例性的，对于接入网网元接收到的至少一条QoS描述信息中的每条QoS描述信息，接入网网元可以根据网元信息集合确定该条QoS描述信息中接入网网元对应的一个或多个QoS参数类型，并根据接入网网元对应的一个或多个QoS参数类型确定接入网网元对应的一个或多个QoS参数要求。而后，接入网网元可以根据自身相关QoS参数要求确定每条QoS描述信息是否能被接入网网元满足。其中，接入网网元满足的QoS描述信息集合可包含0条、1条或多条QoS描述信息。接入网网元可以从接入网网元满足的QoS描述信息集合中确定一条QoS描述信息作为目标QoS描述信息，以便于网络或终端设备根据该目标QoS描述信息执行资源分配、调度、门限控制等服务质量策略。
在本申请的另一种设计中，若QoS描述信息中不含有网元信息集合或接入网网元未获取到网元信息集合的情况下，接入网网元可以根据自身能力识别QoS描述信息中与自身相关的QoS参数要求，并根据自身相关的QoS参数要求确定接入网网元满足的QoS描述信息集合，而后，接入网网元从接入网网元满足的QoS描述信息集合中选择一条QoS描述信息作为目标QoS描述信息。
在一种可能的实现方式中，接入网网元可以将满足接入网网元对应的一个或多个QoS描述信息中数字编号最小/最大的确定为目标QoS描述信息；或者，接入网网元可以从接入网网元满足的QoS描述信息集合中选择一条对空口资源消耗最少的QoS描述信息作为目标QoS描述信息；或者，接入网网元可以随机从接入网网元满足的QoS描述信息集合中选择一条QoS描述信息作为目标QoS描述信息。接入网网元还可以存在其他确定目标QoS描述信息的方式，此处不限定。
在一种可能的设计中，接入网网元从接收到的至少一条QoS描述信息中确定QoS描述信息的第一集合，QoS描述信息的第一集合包括接入网网元接收到的至少一条QoS描述信息的部分或全部QoS描述信息。接入网网元将第一集合发送给业务对应的终端设备。示例性地，接入网网元向终端设备发送接入网相关资源建立/更新消息，接入网相关资源建立/更新消息包含第一集合。接入网网元接收终端设备发送的QoS描述信息的第二集合，第二集合是第一集合的的子集；即第二集合中的任一条QoS描述信息都属于第一集合。接入网网元从第二集合中确定业务的一条目标QoS描述信息。
在一种可能的设计中，接入网网元将从核心网网元接收到的至少一条QoS描述信息发送给业务对应的终端设备，终端设备确定QoS描述信息的第二集合，第二集合包括接入网网元接收到的至少一条QoS描述信息的部分或者全部QoS描述信息。接入网网元接收终端设备发送的QoS描述信息的第二集合。接入网网元从终端设备发送的QoS 描述信息的第二集合确定QoS描述信息的第一集合，第一集合包括第二集合的部分或全部的QoS描述信息。接入网网元从第一集合中确定业务的一条目标QoS描述信息。
在一种可能的实现方式中，若接入网网元接收到核心网网元发送的网元信息和/或第五指示信息，那么接入网网元在向终端设备发送第一集合或至少一条QoS描述信息的同时，还可将网元信息集合和/或第五指示信息发送给业务对应的终端设备。
在一种可能的实现方式中，当终端设备确定不满足至少一条QoS描述信息中的任何一条QoS描述信息中的QoS参数要求集合时，即终端设备无法确定终端设备满足的QoS描述信息第二集合时，终端设备向接入网网元发送第四指示信息，第四指示信息用于指示终端设备不满足业务的服务质量要求和/或不满足的具体Qos参数要求。需要说明的是，第四指示信息可通过接入网网元、AMF、SMF传递至PCF甚至业务服务器或数据分析网元，以便SMF或PCF或业务服务器或数据服务器做成相应的策略调整。
在一种可能的设计中，终端设备根据是否接收到第五指示信息决定是否发送第四指示信息，即当终端设备接收到第五指示信息且确定不满足获取的任何一条Qos描述信息时，终端设备发送第四指示信息；否则，不发送第四指示信息。
接入网网元可以是终端设备发送的Qos描述信息的第二集合中确定一条QoS描述信息作为目标QoS描述信息，以便于网络或终端设备根据该目标QoS描述信息执行资源分配、调度、门限控制等服务质量策略。
在一种可能的实现方式中，如果接入网网元相关参数发生变化，例如因用户数增加导致单用户资源不足、或因业务对应的用户移动到信号弱覆盖区、或因时间段发生变化等，而导致接入网网元不再满足目标QoS描述信息中的QoS参数要求。接入网网元可以通过自身识别或者根据网元信息集合识别出的与接入网网元相关的QoS参数要求，确定网络哪些参数变化可能导致接入网网元不再满足目标QoS描述信息中的QoS参数要求。例如上述举例中，接入网需先确定用户资源要求、无线信号强弱要求、时间段要求三者是对自身的QoS参数要求，后续才能确定现网中这些实际参数发生变化时可能会导致接入网网元不再满足目标QoS描述信息中的QoS参数要求。
在一种可能的实现方式中，若接入网网元对应的参数不再满足目标QoS描述信息中的QoS参数要求，接入网网元从至少一条QoS描述信息中重新确定业务的一条目标QoS描述信息，其中，接入网网元对应的参数满足重新确定的目标QoS描述信息中接入网网元的QoS参数要求。
在一种可能的实现方式中，接入网网元向核心网网元和/或终端设备发送重新确定的目标QoS描述信息。
在一种可能的实现方式中，接入网网元从接入网网元接收到的至少一条QoS描述信息中重新确定业务的一条QoS描述信息之后，接入网网网元可以向核心网网元发送第一指示信息，第一指示信息用于指示接入网网元不再能满足目标QoS描述信息和/或不再满足目标QoS描述信息的具体QoS参数要求。核心网网元可以做出相应的策略调整，如发起新一轮的QoS描述信息选择流程。例如，当接入网无法再满足任一QoS描述信息中的GFBR要求时，接入网网元可以将第一指示信息设置为不满足GFBR的要求，当然接入网网元还可能因为同时不满足多个Qos要求参数或者不满足多个参数之间的联合关系要求而不满足业务的服务质量要求，那么接入网网网元根据实际情况来设置第一 指示信息。
在一种可能的实现方式中，接入网网元向核心网网元发送第一指示信息之前，接入网网元接收核心网网元发送的第二指示信息，第二指示信息用于指示接入网网元在不满足目标QoS描述信息时，接入网网元发送第一指示信息。
在一种可能的实现方式中，当接入网网元不满足业务的服务质量要求时，即当接入网网元不再满足目标QoS描述信息中的QoS参数要求，且接入网网元自身更新后的相关参数不满足至少一条QoS描述信息任何一条QoS描述信息时，接入网网网元可以向核心网网元发送第四指示信息，第四指示信息用于指示接入网网元不满足业务的服务质量要求和/或不满足的具体QoS参数要求。
在一种可能的设计中，接入网网元接收核心网网元发送的第五指示信息，第五指示信息用于指示接入网网元不满足业务的服务质量要求时，接入网网元向核心网网元发送第四指示消息。
在一种可能的设计中，接入网网元根据是否接收到第五指示信息决定是否发送第四指示信息，即当终端设备接收到第五指示信息且确定不满足获取的任何一条Qos描述信息时，终端设备发送第四指示信息；否则，不发送第四指示信息。其中，第五指示信息用于指示接入网网元确定不满足业务的服务质量要求时，发送第四指示信息，这里不满足业务的服务质量要求具体可以是指不满足接收到的任何一条QoS描述信息的QoS参数要求。
当接入网网元不再满足业务的服务质量要求时，即当接入网网元不再满足目标QoS描述信息中的QoS参数要求，且接入网网元自身更新后的相关参数不满足至少一条QoS描述信息任何一条QoS描述信息时，接入网网元向核心网网元发送切换请求消息或向终端设备发送重定向信息，其中，切换请求消息用于将终端设备切换至其他接入网网元，重定向信息用于将终端设备重定向至其他接入网网元。
在一种可能的实现方式中，接入网网元接收核心网网元发送的第三指示信息，第三指示信息用于指示接入网网元在确定不满足业务的服务质量要求时，接入网网元将终端设备切换或重定向至其他接入网网元。其中，不满足业务的服务质量要求即不满足至少一条Qos描述信息中的任何一条Qos描述信息。其中，其他接入网网元包括同网络和异网的其他接入网网元。例如，当接入网网元为5G网络NG RAN时，那么NG RAN可能触发将终端设备切换至5G网络的其他NG RAN、5G网络的EUTRNA、4G网络的EUTRAN、3G网络的UTRAN、2G网络的GERAN中的一个。在一种可能的实现方式中，接入网网元在发送切换请求消息或重定向信息之前，接入网网网元还需确定其他接入网网元是能够满足至少一条QoS参数信息中的任何一条QoS参数信息中的QoS参数要求的接入网网元。
在一种可能设计方式中，接入网网元根据是否从核心网网元接收到第三指示信息，而决定是否将终端设备切换或重定向至其他接入网网元。即若接入网设备获取核心网网元发送的第三指示信息，且第三指示信息用于指示接入网网元在确定不满足业务的服务质量要求时需将将终端设备切换至其他接入网网元，则接入网网元发送切换请求消息；若接入网网元获取核心网网元发送的第三指示信息，且第三指示信息用于指示接入网网元在确定不满足业务的服务质量要求时需将终端设备重定向至其他接入网网 元，则接入网设备发送发送重定向信息；若接入网网元未接收到第三指示信息，则接入网网元可以不发送切换消息和重定向信息。
210、在一种可能的实现方式中，当接入网网元确定不满足至少一条QoS描述信息中的任何一条QoS描述信息中的QoS参数要求集合时，即接入网网元无法确定目标QoS描述信息时，接入网网元向AMF发送第四指示信息，第四指示信息用于指示接入网网元不满足业务的服务质量要求和/或不满足的具体Qos参数要求。
接入网网元设置第四指示信息的具体方法可参考步骤206中第一核心网网元的设置方法，此处不再赘述。需要说明的是，接入网网元发送的第四指示信息可通过AMF、SMF传递至PCF，或更进一步地通过PCF发送至业务服务器或数据分析网元，以便后续SMF或PCF或业务服务器或数据分析网元做出相应的策略调整。
在一种可能的设计中，接入网网元根据是否接收到第五指示信息决定是否发送第四指示信息，即当接入网网元接收到第五指示信息且确定不满足获取的任何一条Qos描述信息时，接入网网元发送第四指示信息；否则，不发送第四指示信息。

接入网网元接收终端设备发送的QoS描述信息的第二集合。
在一种可能的实现方式中，接入网网元从QoS描述信息的第二集合确定QoS描述信息的第一集合，即确定接入网网元满足的QoS描述信息集合。接入网网元确定QoS描述信息的第一集合的方法可以参考步骤205中第一核心网网元的确定方法，此处不再赘述。
322、在一种可能的实现方式中，当接入网网元确定不满足QoS描述信息的第二集合中的任何一条QoS描述信息中的QoS参数要求集合时，即接入网网元无法确定接入网网元满足的QoS描述信息的第一集合时，接入网网元向AMF发送第四指示信息，第四指示信息用于指示接入网网元不满足业务的服务质量要求和/或不满足的具体Qos参数要求。
需要说明的是，接入网网元可以通过AMF向SMF发送第四指示信息，其中AMF起透传第四指示信息的作用，即AMF并不解析第四指示信息。进一步的，第四指示信息可通过接入网网元、AMF、SMF传递至PCF甚至业务服务器，以便PCF或业务 服务器做成相应的策略调整。若接入网网元确定不满足第三集合中的任何一条QoS描述信息中的QoS参数要求集合，下文其他流程步骤可被忽略，不再执行。
在一种可能的设计中，接入网网元根据是否接收到第五指示信息决定是否发送第四指示信息，即当接入网网元接收到第五指示信息且确定不满足获取的任何一条Qos描述信息时，接入网网元发送第四指示信息；否则，不发送第四指示信息。
323、接入网网元从第一集合中确定业务的一条目标QoS描述信息。
具体过程可以参考步骤209的相关说明。
如果接入网网元相关参数发生变化，例如因用户数增加导致单用户资源不足、或因业务对应的用户移动到信号弱覆盖区、或因时间段发生变化等，而导致接入网网元不再满足目标QoS描述信息中的QoS参数要求。接入网网元可以通过自身识别或者根据网元信息集合识别出的与接入网网元相关的QoS参数要求，确定网络哪些参数变化可能导致接入网网元不再满足目标QoS描述信息中的QoS参数要求。例如上述举例中，接入网需先确定用户资源要求、无线信号强弱要求、时间段要求三者是对自身的QoS参数要求，后续才能确定现网中这些实际参数发生变化时可能会导致接入网网元不再满足目标QoS描述信息中的QoS参数要求。
当接入网网元相关参数发生变化时，接入网网元可以执行步骤324、325或326。
324、接入网网元重新确定业务的一条目标QoS描述信息。
接入网网元可以从AMF发送的至少一条QoS描述信息中重新确定业务的一条目标QoS描述信息，具体过程可以参考上述相关描述。
下面以核心网网元为AMF为例进行说明：
325、当接入网网元对应的参数的当前取值无法再满足目标QoS描述信息中的QoS参数要求集合时，接入网网元向AMF发送第一指示信息。
具体的，接入网网元对应的参数的当前取值不满足目标QoS描述信息中的部分或全部QoS参数要求时，接入网网元向AMF发送第一指示信息。第一指示信息用于指示不满足目标QoS描述信息和/或接入网网元不满足目标QoS描述信息中的QoS参数要求。

在一种可能的设计中，接入网网元接收AMF发送的第五指示信息，第五指示信息用于指示接入网网元不满足业务的服务质量要求时，接入网网元向核心网网元发送第四指示消息。
在一种可能的设计中，接入网网元根据是否接收到第五指示信息决定是否发送第四指示信息，即当接入网网元接收到第五指示信息且确定不满足获取的任何一条Qos描述信息时，接入网网元发送第四指示信息；否则，不发送第四指示信息。
326、当接入网网元对应的参数的当前取值无法再满足至少一条QoS描述信息中的任何一条QoS描述信息中的QoS参数要求集合时，接入网网元向AMF发送切换请求消息或向终端设备发送重定向信息，切换请求消息用于将终端设备切换至其他接入网网元，重定向信息用于将终端设备重定向至其他接入网网元。
其中，其他接入网网元包括同网络和异网的其他接入网网元。例如，当接入网网元为5G网络NG RAN时，那么NG RAN可能触发将终端设备切换至5G网络的其他NG RAN、5G网络的EUTRNA、4G网络的EUTRAN、3G网络的UTRAN、2G网络的GERAN中的一个。在一种可能的实现方式中，接入网网元在发送切换请求消息或重定向信息之前，接入网网网元还需确定其他接入网网元是能够满足至少一条QoS参数信息中的任何一条QoS参数信息中的QoS参数要求的接入网网元。
在一种可能的实现方式中，接入网网元接收AMF发送的第三指示信息，第三指示信息用于指示接入网网元在确定不满足业务的服务质量要求时，接入网网元将终端设备切换或重定向至其他接入网网元。其中，不满足业务的服务质量要求即不满足至少一条Qos描述信息中的任何一条Qos描述信息。
在一种可能设计方式中，接入网网元根据是否从AMF接收到第三指示信息，而决定是否将终端设备切换或重定向至其他接入网网元。即若接入网设备获取AMF发送的第三指示信息，且第三指示信息用于指示接入网网元在确定不满足业务的服务质量要求时需将将终端设备切换至其他接入网网元，则接入网网元发送切换请求消息；若接入网网元获取AMF发送的第三指示信息，且第三指示信息用于指示接入网网元在确定不满足业务的服务质量要求时需将终端设备重定向至其他接入网网元，则接入网设备发送发送重定向信息；若接入网网元未接收到第三指示信息，则接入网网元可以不发送切换消息和重定向信息。

需要说明的是，在本申请实施例提供资源分配的方法中，不同网元实体之间的交互可以基于点对点接口，也可以基于服务化接口，在此不做限制。本申请实施例中以基于服务化接口的交互方式为例，对下述资源分配的方法的流程进行说明。
图16为本申请实施例提供的一种资源分配的方法的流程图。其中，资源分配方法包括业务的服务质量信息传输方法。图16将结合图2进行描述。
首先说明一点，图16所述的方法适用于数据分析网元针对某种业务可训练并向网络提供至少一套QoS描述信息的场景。
针对某个业务，之所以是至少一套QoS描述信息，示例性的，考虑到针对垂直行业的业务体验要求(比如业务MOS分大于3.0)，包时延数据与丢包率数据是冲突的，
比如1，在弱覆盖下，RAN可以多传几次数据包以保证丢包率，但是这种情况下，会增大包时延，进一步地，可能会增大流比特率；
比如2，在强覆盖下，RAN不需要传多次数据包，这种情况下包丢包率和包时延都可以保证，进一步地，可能会减小流比特率。
因此，针对一个业务，存在一套或者多套QoS描述信息。
具体地，数据分析网元基于时变性网络数据或者业务数据或者终端数据以及对应的业务体验数据通过大数据方法得到业务的至少一套QoS描述信息，过程如下1601和1602两个步骤描述。
1601、数据分析网元获取业务的训练数据。
数据分析网元首先从业务服务器(如AF)、接入网网元(如RAN)、用户面功能网元(如UPF)、终端设备(如UE)、移动性管理功能网元(如AMF)、会话管理功能网元(如SMF)、策略控制功能网元(如PCF)等网元分别收集数据，然后通过业务标识、业务流标识、终端标识、业务流所在的会话标识、每个网元上都有的关联标识、时间等信息将各个网元的数据关联起来，得到完整的训练数据。训练数据中包括，
1)业务体验数据，来自AF网元；
2)其他影响业务体验数据的时变性参数数据，包括，
a.来自AF网元的TCP拥塞窗口数据、TCP接收窗口数据、抖动缓存数据、媒体编码类型以及编码速率数据、缓存数据、至少一个数据类型的数据；
b.来自RAN网元流比特率数据、丢包率数据、时延数据、无线信道质量数据、至少一个数据类型的数据；
c.来自UPF网元的流比特率数据、丢包率数据、时延数据、至少一个数据类型的数据；
d.来自UE的流比特率数据、丢包率数据、时延数据、至少一个数据类型的数据、TCP拥塞窗口数据、TCP接收窗口数据、抖动缓存数据、媒体编码类型以及编码速率数据、缓存数据、CPU占用率、内存占用率至少一个数据类型的数据；
e.等等。
其他具体过程还可以参考图2中的步骤201的描述，此处不再赘述。
1602、数据分析网元生成业务的至少一条第三QoS描述信息。
具体过程可以参考图2中的步骤202的描述。其中，为便于与后续步骤的第一、第二QoS描述信息进行区分，这里用了第三QoS描述信息，但实际上所述至少一条第三QoS描述信息与步骤202中数据分析网元生成业务的至少一条QoS描述信息具备相同的含义，此处不再赘述。
示例性地，数据分析网元基于线性回归(Linear Regression)方法得到业务体验与其他影响业务体验数据的时变性参数数据的关系模型，即业务体验模型，如下
h(x)＝w 0x 0+w 1x 1+w 2x 2+w 3x 3+…+w Dx D      (1)
公式(1)中,
‐ h(x)是某个业务的业务体验数据，例如业务的MOS；
‐ X＝(x0,x 1 x 2,x 3,…,x D)特征向量，示例性的，x 1表示包时延，x 2标识丢包率，x 3标识流比特率，...x D表示TCP拥塞窗口，x 0为常数1x 0；
‐ W＝(w 0,w 1 w 2,w 3,…,w D)是参数向量，也称作权重向量，w i标识第i个参数对于业务体验数据影响的权重的大小；
数据分析网元基于多目标决策制定(Multiple Criteria Decision Making，MCDM)中常用的多目标优化模型(Multiple Optimization Model)得到某个业务的至少一套第三QoS描述信息，具体地，
步骤(1)、业务方(来自于AF网元)的业务体验要求，比如业务的MOS大于3.0，则基于业务体验模型可以得到多目标优化问题的一个约束条件，如下，
3.0＝w 0x 0+w 1x 1+w 2x 2+w 3x 3+…+w Dx D        (2)
步骤(2)、数据分析网元通过统计知道每个时变参数的范围，即每个时变参数的范围本身各自为一个约束条件，比如RAN侧无线信道质量中RSRP的范围如下，
RSRP∈[-140,40]dbm        (3)
步骤(3)、数据分析网元设计多个目标函数，示例如下，
Minmize:Flow Bit Rate
Maximize:Packet Delay
Maximize:Packet Rrror Rate
步骤(4)、数据分析网元基于遗传算法(Generic Algorithm，GA)得到某个业务的至少一条第三QoS描述信息。
1603、数据分析网元向策略控制功能网元发送至少一条第三QoS描述信息。相应的，策略控制功能网元从数据分析网元接收至少一条第三QoS描述信息。
在一种可能的实现方式中，数据分析网元向策略控制功能网元发送至少一条第三QoS描述信息之前，数据分析网元接收策略控制功能网元发送业务的QoS描述信息请求。QoS描述信息请求用于请求业务的至少一条第三QoS描述信息，也即数据分析网元向策略控制功能网元发送至少一条第三QoS描述信息的操作是由业务的QoS描述信息请求而触发的。QoS描述信息请求可包括业务的业务标识信息(例如，公共陆地移动网络(public land mobile network，PLMN)ID、业务标识(service ID)和分析标识(analytic ID))。其中，业务的标识信息可以是由数据分析网元提前统一为任一类业务分配并发送给对应的业务服务器的。数据分析网元可以通过NEF与业务服务器通信，数据分析网元、NEF和业务服务器之间可以通过统一的北向接口通信。具体的，业务服务器可以通过统一的北向接口向数据分析网元请求业务标识信息分配，或业务服务器经统一的北向接口向NEF请求业务标识信息分配，再由NEF向数据分析网元请求业务标识信息分配。业务标识信息也可以是其他网元向PCF提供的，例如在业务对应的会话建立过程中，由SMF或终端设备向PCF提供的业务标识信息，此处并不限定。其中，业务标识信息可以是业务类型信息。需要说明的是，除业务标识信息外，业务的QoS描述信息请求还可以包含以下信息的一项或多项：执行该业务的终端设备的标识信息(IMSI、SUPI、UE IP地址、UE群组标识，UE类型标识等)、终端设备的位置信息(TA或TA列表或小区列表(cell list))和终端设备所在的数据网络的名称(如DNN)、终端设备所在切片标识信息(如NSSAI、S-NSSAI、NSI等)、时间信息，该操作的目的是按以下一种粒度或多种粒度的结合从数据分析网元获取业务的至少一条第三QoS描述信息：终端设备粒度、用户群组粒度、位置区域粒度，DNN粒度，切片粒度，时间粒度。
需要说明的是，在一种可能的设计中，上述策略控制功能网元向数据分析网元发送业务的QoS描述信息请求操作又可以由其接收到的业务建立请求消息而触发，即策略控制功能网元发送业务的QoS描述信息请求之前，策略控制功能网元接收该业务的业务服务器发送业务建立请求，所述业务建立请求用于为所述业务建立业务流。需要说明的是，一般通信网络会应业务服务器的要求为该业务流建立专用的数据包传输通道(例如专用承载bear或服务质量流QoS flow)。其中，业务建立请求中包含所述业务的业务标 识信息和/或业务描述信息，业务描述信息可以包含以下信息中的一项或者多项：所述业务流所属的业务标识、IP过滤信息、媒体带宽要求、流量路由信息、抖动缓存要求、媒体编码类型要求、所述媒体编码类型要求的编码速率要求、TCP拥塞窗口要求、TCP接收窗口要求、缓存要求和至少一个数据类型的值要求。例如，在5G网络中，业务建立请求可以为业务服务器向PCF发送的认证授权请求消息(例如策略认证授权请求消息)，认证授权请求消息包括业务标识信息，用于指示建立业务标识信息对应的业务。另外，认证授权请求消息中还包含业务描述信息。在此种设计方法中，若策略控制功能网元获取业务建立请求中包含的业务描述信息，则策略控制功能网元在向数据分析网元发送的业务的QoS描述信息请求中也可以包含业务的描述信息，以便于数据分析网元根据业务的描述信息生成所述业务的至少一条第三QoS描述信息。
对应上述实现方式，若数据分析网元接收策略控制功能网元发送业务的QoS描述信息请求消息，数据分析网元可以向策略控制功能发送Qos描述信息请求响应，Qos描述信息请求响应中包括业务的至少一条第三Qos描述信息。至少一条第三Qos描述信息可以通过表格、图像、函数或描述文件等形式呈现，本申请不做限定。
在另一种可能的实现方式中，策略控制功能网元可向数据分析网元发送业务的QoS描述信息订阅请求，用于向所述数据分析网元订阅所述业务的QoS描述信息，其中，业务的QoS描述信息订阅请求可包括所述业务的标识信息。需要说明的是，除业务标识信息外，业务的QoS描述信息请求还可以包含以下信息的一项或多项：执行该业务的终端设备的标识信息(IMSI、SUPI、UE IP地址、UE群组标识，UE类型标识等)、终端设备的位置信息(TA或TA列表或小区列表(cell list))和终端设备所在的数据网络的名称(如DNN)、终端设备所在切片标识信息(如NSSAI、S-NSSAI、NSI等)、时间信息，该操作的目的是按以下一种粒度或多种粒度的结合向数据分析网元订阅业务的至少一条第三QoS描述信息：终端设备粒度、用户群组粒度、位置区域粒度，DNN粒度，切片粒度，时间粒度。在一种可能的设计中，业务的QoS描述信息订阅请求中可包括通知触发条件，其中，通知触发条件用于指示数据分析网元向策略控制功能网元通知所述订阅的业务的QoS描述信息的触发条件。
对应该种实现方式，数据分析网元可按订阅请求向策略控制功能网元发送业务的QoS描述信息通知，业务的QoS描述信息通知包含业务的至少一条第三QoS描述信息。例如，可根据订阅请求中的业务标识信息按业务粒度地向数据分析网元推送业务的第三QoS描述信息。数据分析网元还可进一步地，按以下一种粒度或多种粒度的结合向策略控制网元推送业务的至少一条第三QoS描述信息：终端设备粒度、用户群组粒度、位置区域粒度，DNN粒度，切片粒度，时间粒度。在一种可能的设计中，若订阅请求中包含通知触发条件，在进一步的，数据分析网元还可在满足触发条件时才向数据分析网元发送业务的至少一条第三QoS描述信息。
1604、策略控制功能网元根据第三QoS描述信息确定至少一条第一QoS描述信息。
例如，至少一条第一QoS描述信息中的每条第一QoS描述信息包括用户面功能网元的QoS信息和接入网网元的QoS信息，还包括以下一项或者多项：业务服务器的QoS信息、终端设备的QoS信息或策略控制功能网元的QoS信息。其中，接入网网元的QoS信息包括以下一项或者多项：QoS参数类型、QoS参数要求和接入网网元信息。 用户面功能网元的QoS信息包括以下一项或者多项：QoS参数类型、QoS参数要求和用户面功能网元信息。业务服务器的QoS信息包括以下一项或者多项：QoS参数类型、QoS参数要求和业务服务器信息。终端设备的QoS信息包括以下一项或者多项：QoS参数类型、QoS参数要求和终端设备信息。策略控制功能网元的QoS信息包括以下一项或者多项：QoS参数类型、QoS参数要求和策略控制功能网元信息。另外，上述网元信息可用于指示QoS信息适用的网元，例如，用户面功能网元信息用于指示用户面功能网元的QoS信息适用于UPF；设备信息可用于指示QoS信息适用的设备，例如，终端设备信息用于指示终端设备的QoS信息适用于终端设备。其中，网元信息可以包括网元类型信息或标识信息，设备信息可以包括设备类型信息或标识信息。网元信息用于指示对应的QoS参数要求可以应用的一个或一类网元，设备信息用于指示对应的QoS参数要求可以应用的一个或一类设备，其具体的含义和举例说明可参见步骤202。
在一种可能的设计中，上述各功能网元或设备的QoS参数要求包括以下一项或者多项信息：时间信息要求、位置信息要求、保证流比特率GFBR要求、最大流比特率MFBR要求、平均时间窗口大小要求、抖动缓存区大小要求和TCP拥塞窗口要求、TCP接收窗口要求、缓存要求、至少一个数据类型的值要求和无线接入类型(Radio access type，RAT)要求。
在一种可能的设计中，至少一个数据类型的值要求的获取过程，具体可包括：功能网元或设备根据第一数据类型的第一数据值确定第二数据值，其中，第一数据值属于第一数值空间，第二数据值属于第二数值空间，第一数据类型为至少一个数据类型中的任何一项。
在另一种可能的设计中，至少一个数据类型的值要求的获取过程，具体还可包括：功能网元或设备根据第二数据类型的第三数据值确定第四数据值，其中，第三数据值属于第三数值空间，第四数据值属于第四数值空间，第二数据类型为至少一个数据类型中的任何一项。
上述两种设计中，可选的，第二数值空间与第四数值空间相同。为便于功能网元或设备处理，所有的数据类型的数值空间可以相同，不需要数据分析网元再进一步处理到同一个数值空间。
在另一种可能的设计中，至少一个数据类型的值要求的获取过程，还可以包括：功能网元或设备第三数据类型的第五数据值确定第六数据值，其中，第五数据值属于第五数值空间，第六数据值属于第六数值空间，第三数据类型为至少一个数据类型中的任何一项。
可选的，第二数值空间、第四数值空间、第六数值空间两两相等。
其中，功能网元或设备可以通过归一化处理第一数据类型的第一数据值确定第二数据值，或者可以通过归一化处理第二数据类型的第三数据值确定第四数据值，或者可以通过归一化处理第三数据类型的第五数据值确定第六数据值，所述归一化处理包括将所述数据类型的物理数据值映射到固定的数值空间。其中所述归一化处理主要是采用最大最小值归一化方法、Z-Score归一化方法等将每个数据类型的物理数据值映射到固定的数值空间，这种处理一方面便于在大数据分析过程中提高模型训练收敛速度，另一方面提供了一种特征数据传输方式。
例如，策略控制功能网元根据从数据分析网元接收的业务的至少一条第三QoS描述信息中确定至少一条第一QoS描述信息(即策略控制功能网元满足的第三QoS描述信 息集合)，策略控制功能网元满足的第三QoS描述信息集合包括至少一条第三QoS描述信息的部分或者全部第三QoS描述信息。策略控制功能网元确定满足的第三QoS描述信息集合的具体过程可以参考图2中的步骤205，其中，步骤205中的第一核心网网元在本实施例中具体为策略控制功能网元，步骤205中第三集合在本实施例中具体为第三QoS描述信息集合。
例如，若每条第三QoS描述信息对应有一个无线接入类型要求时，其中无线接入类型要求信息用于指示该条第三QoS描述信息适用的无线接入类型。在一种可能的设计中，PCF可以根据执行业务的终端设备当前所在的无线接入类型对每条第三QoS描述信息进行筛选，使得当前所在的无线接入类型符合选择出的每条第三QoS描述信息中的无线接入类型要求，则PCF可将所述选择出的每条第三QoS描述信息作为自身能满足的第三QoS描述信息集合。
通过步骤1606，会话管理功能网元确定出的每条第二QoS描述信息也对应有一个无线接入类型要求。此时，优选地，会话管理功能网元可进一步根据无线接入类型要求确定至少一条接入网网元QoS信息，使得确定出的至少一条接入网网元QoS信息能适用于终端设备当前所在的接入网网元。
在一种可能的设计中，在步骤1603中，若策略控制功能网元从业务服务器获取了业务的描述信息，例如业务描述信息包括业务的以下信息的一项或多项：业务流所属的业务标识、IP过滤信息、媒体带宽要求、流量路由信息、抖动缓存要求、媒体编码类型要求、所述媒体编码类型要求的编码速率要求、TCP拥塞窗口要求、TCP接收窗口要求、缓存要求和至少一个数据类型的值要求，策略控制功能网元可根据业务的描述信息从获取的至少一条第三QoS描述信息确定所述至少一条第一QoS描述信息。在此种设计方式中，实际上，策略控制功能网元将从数据分析网元获取的第三QoS描述信息中与业务服务器相关的参数要求也作为对策略控制功能网元自身的QoS参数要求，其根据业务的描述信息中的部分或全部信息，代替了AF做QoS描述信息的操作，也即在此种设计方式中，AF可无需参与QoS描述信息筛选的流程。
在一种可能的设计中，策略控制功能网元可以将策略控制功能网元满足的第三QoS描述信息集合发送给业务服务器，示例性的，策略控制功能网元向业务服务器发送策略认证授权消息，策略认证授权消息包括策略控制功能网元满足的第三Qos描述信息集合。业务服务器确定自身能满足的第三QoS描述信息集合并将该集合反馈给策略控制功能网元，示例性的，业务服务器向策略控制功能网元发送策略认证授权消息，策略认证授权消息包括业务服务器满足的第三Qos描述信息集合。策略控制功能网元将业务服务器能满足第三QoS描述信息集合作为策略控制功能网元满足的第三QoS描述信息集合(即所述至少一条第一QoS描述信息)发送给会话管理功能网元。其中，业务服务器确定自身满足的第三QoS描述信息集合的方法可以参考步骤205中第一核心网网元的确定方法，此处不再赘述。
在一种可能的设计中，策略控制功能网元可以将从数据分析网元获取的业务的至少一条第三QoS描述信息先发送给业务服务器，以便于业务服务器筛选出自身满足的第三Qos描述信息集合后发送给策略控制功能网元。其中，业务服务器确定自身满足的第三QoS描述信息集合的方法可以参考步骤205中第一核心网网元的确定方法，此处不 再赘述。策略控制功能网元再对业务服务器满足的第三QoS描述信息集合进行筛选，确定出策略控制功能网元满足的第三QoS描述信息集合，其中，策略控制功能网元确定自身满足的QoS描述信息集合的方法也可以参考步骤205中第一核心网网元的确定方法。策略控制功能网元再将自身能满足第三QoS描述信息集合作为所述至少一条第一QoS描述信息发送给会话管理功能网元。
1605、策略控制功能网元向会话管理功能网元发送至少一条第一QoS描述信息。相应的，会话管理功能网元从策略控制功能网元接收至少一条第一QoS描述信息。
在一种可能的设计中，策略控制功能网元发送至少一条第一QoS描述信息可以是策略控制功能网元满足的第三QoS描述信息集合。
示例性的，当策略控制功能网元为PCF，会话管理功能网元为SMF时，PCF可以向SMF发送策略控制消息(如服务化接口消息Npcf-SMPolicyControl_UpdateNotify request)，策略控制消息包括PCF满足的第三Qos描述信息集合。PCF可在接收AF发送的认证授权消息后向SMF发送策略控制消息，其中，AF向PCF发送认证授权消息的目的是请求网络为业务建立专用的业务流(例如QoS flow)，PCF向SMF发送策略控制消息的目的是请求SMF触发专用业务流(QoS flow)的建立流程。
1606、会话管理功能网元根据至少一条第一QoS描述信息确定用户面功能网元能满足的至少一条第二QoS描述信息。其中，至少一条第二QoS描述信息为至少一条第一QoS描述信息中的一条或者多条。
例如，用户面功能网元满足第二QoS描述信息可以是指用户面功能网元满足第二QoS描述信息中包含的用户面功能网元的QoS信息。
在一种可能的实现方式中，会话管理功能网元可以先获取的每条第一QoS描述信息包含的用户面功能网元(如UPF)的QoS信息，例如会话管理功能网元可以根据用户名功能网元信息识别每条第一QoS描述信息包含的用户面功能网元的QoS信息。会话管理功能网元再将每条第一QoS描述信息的用户面功能网元的QoS信息发送给用户面功能网元，以便查询获知用户面功能网元对用户面功能网元QoS信息的满足情况。会话管理功能网元获取用户面功能网元发送的用户面功能网元的选择信息，其中，选择信息中包含用户面管理网元对每条第一QoS描述信息中包含的用户面功能网元QoS信息的满足情况。选择信息中的具体表现方式可以包括多种形式，对此不做限定。例如，选择信息具体可以为二进制数值(0或1)，其中二进制数值表示UPF对每条第一QoS描述信息包含的用户面功能网元的QoS信息是否满足(例如，0表示不满足，1表示满足)；又如选择信息还可以是UPF返回的能满足的用户面功能网元QoS信息(例如，UPF将自身能满足的QoS信息返回告知SMF，自身不能满足的QoS信息不返回)。会话管理网元根据选择信息确定至少一条第二QoS描述信息，其中每条第二QoS描述信息对应为用户面功能网元能满足的第一QoS描述信息。
例如，当会话管理功能网元为SMF，用户面功能网元为UPF时，SMF向UPF发送N4接口会话建立/修改请求消息，N4接口会话建立/修改请求消息中携带每条第一QoS描述信息中包含的UPF对应QoS信息(如GFBR要求，MFBR要求)。UPF可以根据当前自身的状态或能力对接收到的UPF QoS信息进行筛选，获取UPF对每条第一QoS描述信息中UPF QoS信息的满足情况。UPF向SMF发送UPF的选择信息，其中选择信息用于 指示UPF对UPF QoS信息的满足情况。
在另一种可能的实现方式中，若会话管理功能网元保存或配置了用户面功能网元的QoS相关能力信息或状态信息，则会话管理功能网元可以直接根据上述用户面功能网元的QoS相关能力信息或状态信息对至少一条第一QoS描述信息选择用户面功能网元满足的第二QoS描述信息，即不必再将用户面功能网元的QoS信息发送给用户面功能网元。
通过对至少一条第一QoS描述信息中每条进行判断，会话管理功能网元可确定出0条、1条或多条第二QoS描述信息，其中每条第二QoS描述信息属于会话管理功能网元从策略控制功能网元接收到的至少一条第一QoS描述信息中的一条。当会话管理功能网元可确定出1条或多条第二QoS描述信息，后续执行步骤1607；反之，当会话管理功能网元可确定出0条第二QoS描述信息，即用户面功能网元无法满足任何一条第一QoS描述信息时，则后续可选地执行步骤1606A。
1606A、可选地，会话管理功能网元向策略控制功能网元上报第一通知信息，第一通知信息用于通知所述策略控制功能网元所述用户面功能网元无法满足所述至少一条第一QoS描述信息中的任何一条。
示例性的，当策略控制功能网元为PCF，会话管理功能网元为SMF时，SMF可以向PCF发送策略控制消息(如服务化接口消息Npcf-SMPolicyControl_UpdateNotify response)，策略控制消息包括第一通知信息。其中，可选地，策略控制消息还可以包含业务流建立失败的指示信息，所述业务流建立失败的指示信息用于告知业务服务器AF业务流建立失败。
通过上述方法可以使策略控制功能网元根据第一通知信息重新确定至少一条第一QoS描述信息并发送给会话管理功能网元，使会话管理功能网元可以重新选择第二QoS描述信息。
可选地，在本步骤所述方法中，会话管理功能网元还可告知策略控制功能网元会话管理功能网元无法满足任何一条第一QoS描述信息每条信息的具体原因值。例如，无法满足第一条第一QoS描述信息的原因值是无法满足其中的GFBR要求，无法满足第二条第一QoS描述信息的原因值是无法满足其中MFBR的要求。
可选地，在本步骤所述的方法中，会话管理功能网元还可向策略控制功能网元发送用户面功能网元对一个或多个用户面功能网元的QoS参数类型的实际测量值。以便于后续策略控制功能网元根据所述测量值重新确定至少一条第一QoS描述信息并发送给会话管理功能网元，使会话管理功能网元可以重新选择第二QoS描述信息和接入网网元Qos信息。例如，会话管理功能网元可以将用户面功能网元无法满足的QoS参数要求对应的QoS参数实际测量值上报给策略控制功能网元，也可以是将用户面功能网元所有QoS参数要求对应的QoS参数实际测量值上报给策略控制功能网元。
1607、会话管理功能网元根据所述至少一条第二QoS描述信息确定至少一条接入网网元的QoS信息。其中，至少一条第二QoS描述信息包括至少一条接入网网元的QoS信息。
具体地，根据至少一条第二QoS描述信息中每条第二QoS描述信息包含的接入网网元的QoS信息，会话管理功能网元确定至少一条接入网网元的QoS信息。
在一种可能的设计中，若会话管理功能网元获取的每条第一QoS描述信息对应有一个无线接入类型要求信息时，其中无线接入类型要求信息用于指示该条第一QoS描述信息适用的无线接入类型。则通过步骤1606，会话管理功能网元确定出的每条第二QoS描述信息也对应有一个无线接入类型要求。此时，优选地，会话管理功能网元可进一步根据无线接入类型要求确定至少一条接入网网元QoS信息，使得确定出的至少一条接入网网元QoS信息能适用于终端设备当前所在的接入网网元。
例如，假设执行业务的终端设备当前在NG RAN接入网网元(如gNB)下，且SMF获取到5条第一QoS描述信息，其中对应的无线接入类型要求分别是NG RAN，EUTRAN，NG RAN，NG RAN，UTRAN。经步骤1606，SMF确定出3条第二QoS描述信息，其中对应的无线接入类型分别是NG RAN，EUTRAN，NG RAN。在本步骤中，优选地，SMF还可进一步只将对应NG RAN的两条第二QoS描述信息中的接入网网元QoS信息确定为至少一条接入网网元QoS信息，该确定出的至少一条接入网网元QoS信息将在步骤1608中发送给NG RAN。需要说明的是，无线接入类型要求可以包含在接入网网元QoS信息中，或第一QoS描述信息中且接入网网元QoS信息之外，或者第一QoS描述信息之外。
1608、会话管理功能网元向接入网网元发送至少一条接入网网元的QoS信息。相应的，接入网网元从会话管理功能网元接收至少一条接入网网元的QoS信息。
例如，会话管理功能网元可以直接向接入网网元发送至少一条接入网网元的QoS信息。而在另一种实现方式中，会话管理功能网元也可能需要经过其他核心网网元(如移动性管理功能网元)向接入网网元发送至少一条接入网网元的QoS信息。其中，其他核心网网元可能无需识别或解析所述至少一条接入网网元的QoS信息，本发明并不做限定。
例如，当会话管理功能网元为SMF，接入网元为gNB时，SMF可以经AMF向gNB发送N2接口会话管理信息(N2 SM information)，N2 SM information包含至少一条接入网网元的QoS信息。具体地，SMF向AMF发送N2消息直传请求(如Namf_Communication_N1N2MessageTransfer),其中N2消息直传请求中包含N2 SM information,AMF向gNB发送N2接口消息(如N2 session request)，N2接口消息中包含N2 SM information。这里，SMF向gNB发送N2 SM information的目的是为业务建立专用的业务流(QoS flow)。
经过步骤1607和1608，会话管理功能网元将用户面功能网元能满足的QoS描述信息中的接入网网元的QoS信息筛选出来，以便于会话管理功能网元仅将接入网网元的QoS信息发送给接入网网元，而其他功能网元对应的QoS信息(尤其是业务服务器的QoS信息)不发送给接入网网元，从而实现接入网网元不感知业务信息的目的，由此提高了安全性。
1609、接入网网元从至少一条接入网网元的QoS信息中确定目标接入网网元的目标QoS信息。
在一种可能的设计方式中，对于接收到的至少一条接入网网元QoS信息中的每条接入网网元的QoS信息，接入网网元可直接确定该条信息中对接入网网元的一个或多个QoS参数类型和/或QoS参数要求。
在另一种可能的设计方式中，若接入网网元的QoS信息中包含了接入网网元信息，则接入网网元可根据每条接入网网元Qos信息中包含的接入网网元信息确定该接入网网元Qos信息中对接入网网元的一个或多个QoS参数类型和/或QoS参数要求。其中，接入网网元信息用于指示接入网网元QoS信息中与接入网网元相关的QoS参数类型和/或QoS参数要求。该方式一般适用于会话管理网元向接入网网元发送接入网网元的QoS信息的同时还发送了终端设备或其他网元设备对应的QoS信息的场景，此处不做限定。
在另一种可能的设计方式中，对于每条接入网网元的QoS信息，接入网网元判断是否能满足该条信息中所有的对接入网网元的QoS参数要求。如果满足，则确定接入网网元能满足该条接入网网元的QoS信息；如果不满足(即不满足其中的任一个对接入网网元的QoS参数要求)，则确定接入网网元不能满足该条接入网网元的QoS信息。由此，接入网网元通过对每条接入网网元的QoS信息进行判断，可从接收到的至少一条接入网网元的QoS信息中确定出自身能满足的0条、1条或多条接入网网元的QoS信息。示例性地，假设接入网网元QoS信息中包含了无线接入类型要求时，接入网网元确定自身所属的无线接入类型是否符合每条接入网元网元QoS信息中的无线接入类型要求,据此可确定出自身能满足的0条、1条或多条接入网网元的QoS信息。
当接入网网元可从接收到的至少一条接入网网元的QoS信息中确定出能满足的1条或多条接入网网元的QoS信息时，则后续执行步骤1609A和1610；当接入网网元可从接收到的至少一条接入网网元的QoS信息中确定出自身能满足0条接入网网元的QoS信息时，即接入网网元无法满足接收到的任何一条接入网网元的QoS信息时，则后续可选地执行步骤1609B或1609C。
在一种可能的设计中，步骤1608中接入网网元从会话管理功能网元接收至少一条接入网网元的QoS信息后，接入网网元保存所述至少一条接入网网元的QoS信息，以便于后续接入网网元可能需要重新选择接入网网元的目标QoS信息。
1609A、接入网网元从接入网网元满足的1条或多条接入网网元的QoS信息中选择一条作为接入网网元的目标QoS信息。
例如，在一种可能的实现方式中，若每条接入网网元的QoS信息对应有一个数字编号，则接入网网元可以将接入网网元能满足的至少一条接入网网元的QoS信息中数字编号最小/最大的确定为目标QoS信息。其中，上述数字编号的处理可以由会话管理网元执行。
例如，在另一种可能的实现方式中，接入网网元可以从接入网网元满足的至少一条接入网网元的QoS信息中选择一条对空口资源消耗最少的QoS信息作为接入网网元的目标QoS信息。
例如，在又一种可能的实现方式中，接入网网元可以随机从接入网网元满足的至少一条QoS信息中选择一条QoS信息作为接入网网元的目标QoS信息。
本方案对接入网网元从上述至少一条接入网网元的QoS信息中选择一条作为接入网网元的目标QoS信息的具体方式不做限定。
可选地，接入网网元根据选择的接入网网元目标QoS信息执行无线资源的分配，调度服务质量策略或门限控制服务质量策略等。
1609B、接入网网元向会话管理网元发送第二通知信息，第二通知信息用于通知 会话管理网元接入网网元无法满足其接收到的任何一条接入网网元的QoS信息。
其中，接入网网元无法满足其接收到的任何一条接入网网元的QoS信息具体可指无法满足任何一条接入网网元的QoS信息中包含的对接入网网元的QoS参数要求。
该步骤为可选步骤，通过上述方法可以使后续会话管理网元根据第二通知信息重新确定至少一条接入网网元的QoS信息并发送给接入网网元，使接入网网元重新选择目标QoS信息。
例如，接入网网元可直接向会话管理网元发送第二通信息。而在另一种实现方式中，接入网网元也可能需要经过其他核心网网元(如移动性管理功能网元)向会话管理网元发送第二通信息。其中，其他核心网网元可能无需识别或解析所述第二通信息，本发明并不做限定。
示例性地，当接入网网元为gNB，会话管理网元为SMF时，gNB可经AMF向SMF发送N2 SM information，N2 SM information中包含第二通知信息。其中,可选地，N2 SM information还包含业务流建立失败或成功的指示信息，以便SMF根据业务流建立失败或成功的指示信息执行相应的处理操作，例如当指示业务流建立失败时，SMF可根据指示信息在切换完成后重新触发业务流建立请求流程；又如，当指示业务流建立成功时，SMF可根据指示信息执行后续的切换流程即可。具体地，gNB向AMF发送N2接口消息(如N2 session response),其中N2接口消息中包含N2 SM information，AMF向SMF发送更新会话管理上下请求(如Nsmf_PDUSession_UpdateSMContext Request)，更新会话管理上下请求中包含N2 SM information。这里，gNB向SMF发送N2 SM information的目的是为了响应建立专用的业务流(QoS flow)的请求。
可选地，在本步骤所述方法中，接入网网元还可告知会话管理功能网元接入网网元无法满足任何一条接入网网元的QoS信息每条信息的具体原因值。例如，无法满足第一条接入网网元的QoS信息的原因值是无法满足其中的RSRP要求，无法满足第二条接入网网元的QoS信息的原因值是无法满足其中是空口时延的要求。
可选地，在本步骤所述的方法中，接入网网元还可向会话管理功能网元上报其对接入网网元QoS信息中所包含的一个或多个QoS参数类型的实际测量值。以便于后续会话管理功能网元根据所述测量值重新确定至少一条接入网网元的QoS信息并发送给接入网网元，使接入网网元重新选择目标QoS信息。类似于步骤1606A，接入网网元可以将无法满足的QoS参数要求对应的实际测量值上报给会话管理功能网元，也可以将接入网网元的所有QoS参数要求对应的实际测量值上报给会话管理功能网元。
1609C、接入网网元触发将执行该业务的终端设备切换或重定向至其他接入网网元。
示例性的，接入网网元如何将终端设备重定向至其他接入网网元的方法，以及其他接入网网元的含义，具体可以参考图2中的步骤209，此处不再赘述。
接入网网元如何将终端设备切换至其他接入网网元的方法，可以参考图2中的步骤209的描述。例如，接入网网元向核心网网元发送切换请求消息，其中，切换请求消息用于将终端设备切换至其他接入网网元。在另一种可能的设计中，接入网网元还可直接向其他接入网网元发送切换请求消息，其中切换请求消息用于将终端设备切换至其他接入网网元。
1610、接入网网元向会话管理功能网元发送接入网网元的目标QoS信息。相应的，会话管理功能网元从接入网网元接收接入网网元的目标QoS信息。
在一种的可能的设计中，接入网网元可以将目标QoS信息的部分或全部内容发送给会话管理功能网元，以便于会话管理功能网元据此部分或全部内容映射出接入网网元目标QoS信息对应的第二QoS描述信息的内容。例如，将目标QoS信息中包含的QoS参数类型、QoS参数要求的具体值发送给会话管理功能网元，或者将目标QoS信息中包含的QoS参数类型、QoS参数要求，网元信息的具体值发送给会话管理功能网元。需要说明的是，此种操作方式下，会话管理功能网元根据目标接入网QoS信息可能映射出的多条QoS描述信息，每条QoS描述信息是其在步骤1606中确定出的第二QoS描述信息中的一条。假设会话管理功能网元根据目标接入网QoS信息映射出多条QoS描述信息，则会话管理功能网元可将其中的一条确定为目标QoS描述信息，确定方法本发明不做限制。
在另一种可能的设计中，若接收到的每条接入网网元的QoS信息对应有一个数字编号，则接入网网元可以将目标QoS信息对应的编号发送给会话管理功能网元。以便于会话管理功能网元根据数字编号映射出接入网网元目标QoS信息对应的第二QoS描述信息的内容。其中，上述数字编号的处理可以由会话管理网元执行。
例如，接入网网元可以直接向会话管理功能网元发送接入网网元的目标QoS信息。而在另一种实现方式中，接入网网元也可能需要经过其他核心网网元(如移动性管理功能网元)向会话管理功能网元发送接入网网元的目标QoS信息，其中，其他核心网网元可能无需识别或解析所述接入网网元的目标QoS信息，本发明并不做限定。
例如，当接入网网元为gNB，会话管理网元为SMF时，gNB可经AMF向SMF发送N2 SM information，N2 SM information中包含接入网网元的目的QoS信息。其中,可选地，N2 SM information还包含业务流建立成功的指示信息。具体地，gNB向AMF发送N2接口消息(如N2session response),其中N2接口消息中包含接入网网元的目的QoS信息，AMF向SMF发送更新会话管理上下请求(如Nsmf_PDUSession_UpdateSMContext Request)，更新会话管理上下请求中包含接入网网元的目的QoS信息。这里，gNB向SMF发送N2 SM information的目的是为了响应建立专用的业务流(QoS flow)的请求。
可选地，在本步骤中，接入网网元还可进一步地将接入网网元的目标QoS信息的部分或全部内容发送给终端设备。例如，接入网网元将目标QoS信息中空口相关参数类型、参数要求(如DRB使用频谱，空口信道功率)发送给终端设备，其中，优选地，接入网网元提前确定需要下发的空口参数。此设计以便于终端设备根据接入网网元的目标QoS信息中部分或全部内容来相应地设置终端设备的接入层相关策略。
例如，接入网网元可通过空口资源连接重配置(Radio resource connection reconfiguration)消息将接入网网元的目标QoS信息的部分或全部内容发送给终端设备。
1611、会话管理功能网元根据接入网网元的目标QoS信息确定目标QoS描述信息。
其中，接入网网元的目标QoS信息为步骤1610中会话管理功能网元从接入网网元接收接入网网元的目标QoS信息。目标QoS描述信息属于步骤1606中会话管理功能网元确定出的至少一条第二QoS描述信息中的一条。
会话管理功能网元如何根据接入网网元的目标QoS信息确定目标QoS描述信息的 具体方式，需要对应步骤1610中接入网网元发送目标QoS信息的具体方式，此处不再赘述。
1612、会话管理功能网元将目标QoS描述信息中包含的用户面功能网元的目标QoS信息发送给用户面功能网元。
该步骤以便于用户面功能网元根据最终选择的用户面功能网元的目标QoS信息中的QoS参数类型和QoS参数要求执行用户面功能网元的资源分配、调度服务质量策略或门限控制服务质量策略等。
例如，当会话管理功能网元为SMF，用户面功能网元为UPF时，SMF向UPF发送N4接口会话建立/修改请求消息，N4接口会话建立/修改请求消息中携带目标QoS描述信息中包含的UPF对应QoS信息(如GFBR要求，MFBR要求)。
1613、可选地，当目标QoS描述信息中包括终端设备的目标QoS信息时，会话管理功能网元将目标QoS描述信息中的终端设备的目标QoS信息发送给终端设备。相应的，终端设备从会话管理功能网元接收目标QoS描述信息中的终端设备的目标QoS信息。
在一种可能的设计中，会话管理功能网元可以直接向终端设备发送终端设备的目标QoS信息。而在另一种实现方式中，会话管理功能网元也可能需要经过其他网元(如移动性管理功能网元和接入网网元)向终端设备发送终端设备的目标QoS信息，其中，其他网元可能无需识别或解析所述终端设备的目标QoS信息，本发明并不做限定。
例如，当会话管理功能网元为SMF，终端设备为UE时，SMF可以经AMF和gNB向UE发送N1接口会话管理信息(N1 SM information)，N1 SM information包含终端设备的目标QoS信息。具体地，SMF向AMF发送N1消息直传请求(如Namf_Communication_N1N2MessageTransfer),其中N1消息直传请求中包含终端设备的目标QoS信息,AMF向gNB发送N2接口消息(如N2 session request)，N2接口消息中包含终端设备的目标QoS信息，gNB向UE发送接入层资源修改消息(如AN-specific resource modification)，接入层资源修改消息中包含终端设备的目标QoS信息。
在另一种可能的设计中，会话管理功能网元也可以经业务服务器将终端设备的目标QoS信息发送给终端设备。
例如，当会话管理功能网元为SMF，业务服务器为AF，终端设备为UE时，SMF可直接或经PCF向AF发送终端设备的目标QoS信息，AF向UE发送终端设备的目标QoS信息。该步骤以便于终端设备根据最终选择的终端设备的QoS信息中的QoS参数类型和QoS参数要求执行相应的终端服务质量策略。一般说来，这里会话管理功能网元下发给终端的QoS信息是终端应用层相关QoS参数类型和/或参数要求，如抖动缓存区大小要求等。相应地，终端据此执行的终端服务质量策略是终端的应用层相关服务质量策略，如设置抖动缓存区大小、TCP拥塞窗口大小、TCP接收窗口大小等。
1614、可选地，当目标QoS描述信息中包括策略控制功能网元的目标QoS信息时，会话管理功能网元将目标QoS描述信息中的策略控制功能网元的目标QoS信息发送给策略控制功能网元。相应的，策略控制功能网元从会话管理功能网元接收目标QoS描述信息中的策略控制功能网元的目标QoS信息。
示例性的，当会话管理功能网元为SMF，策略控制功能网元为PCF时，SMF可以向PCF发送会话管理策略控制消息(如Npcf-SMPolicyControl_UpdateNotify response)， 策略控制消息包括策略控制功能网元的目标QoS信息。1615、可选地，当目标QoS描述信息中包括业务服务器的QoS信息时，会话管理功能网元还将目标QoS描述信息中的业务服务器的目标QoS信息发送给业务服务器。相应的，业务服务器从会话管理功能网元接收目标QoS描述信息中的业务服务器的目标QoS信息。
例如，当会话管理功能网元为SMF，业务服务器为AF时，SMF可以直接经服务化接口向AF发送业务服务器的目标QoS信息。在另一种实现方式中，SMF还可经PCF向AF发送业务服务器的目标QoS信息，具体地，SMF向PCF发送会话管理策略控制消息(如Npcf-SMPolicyControl_UpdateNotify response)，策略控制消息包括业务服务器的目标QoS信息，PCF向AF发送认证授权响应消息，认证授权响应消息包含业务服务器的目标QoS信息。
通过该步骤，业务服务器可以根据目标QoS描述信息中的业务服务器QoS信息执行相应的服务质量策略。其中，服务质量策略包括应用层相关策略，例如选择或调整业务编码方式，调整缓存区大小，设置TCP拥塞窗口大小、TCP接收窗口大小等。
相比当前现有技术中QoS机制中的QoS参数的设置通常不够合理或较为固定，本申请实施例中由数据分析网元根据大数据分析方法得出至少一套QoS描述信息，并供策略控制功能网元、会话管理功能网元、接入网网元等网络设备根据网络实际参数进行筛选。而后各网络设备、终端设备和业务服务器根据筛选出的目标QoS描述信息中相应的QoS信息执行相应的服务质量策略，这样因灵活地为业务提供了QoS参数设置，从而保证业务的服务质量。

在一种可能的实现方式中，接入网网元的目标QoS信息为图16步骤1609中确定的接入网网元的目标QoS信息。
在一种可能的实现方式中，接入网网元不再满足目标QoS信息具体可能是因接入网网元本身的相关参数发生变化导致其不再满足接入网网元的目标QoS信息。例如因基站的用户数增加，可用资源量下降，导致基站为单业务、单用户分配的资源(如带宽资源)不再满足业务对基站的资源需求(如GFBR需求)。
在另一种可能的实现方式中，接入网网元不再满足目标QoS信息具体也可能是因执行业务的终端设备位置移动造成的，如业务用户移动到信号弱覆盖区，导致单用户、单业务对应的基站参数(如RSRP)不再满足业务对基站的参数要求(如RSRP要求)。接入网网元不再满足目标QoS信息具体还可能因其他原因，如因时间段发生变化而导致当前的目标QoS信息不再适用，或因业务终端设备的网络位置发送变化而导致当前的目标QoS信息不再适用，本发明不做具体限定。
例如，接入网网元可以通过自身识别或者根据网元信息集合识别出的与接入网网元相关的QoS参数要求，确定网络哪些参数变化可能导致接入网网元不再满足目标QoS信息中的QoS参数要求。例如，接入网需先确定业务用户的资源要求、无线信号强弱 要求、时间段、业务用户所在网络位置四者是对自身的QoS参数要求，后续才能确定现网中这些实际参数发生变化时可能会导致接入网网元不再满足目标QoS信息中的QoS参数要求。
1702、接入网网元从至少一条接入网网元QoS信息中重新确定接入网网元的目标QoS信息。

在执行步骤1707之前，可选地，还包括步骤1705。
1705、会话管理功能网元确定目标QoS描述信息发生改变。
例如，会话管理功能网元确定目标QoS描述信息中的策略控制功能网元的目标QoS信息发生改变。如果会话管理功能网元确定目标QoS描述信息中策略控制功能网元的QoS信息与新的目标QoS描述信息中的策略控制功能网元的QoS信息不同，执行步骤1707。如果会话管理功能网元确定目标QoS描述信息中策略控制功能网元的QoS信息与新的目标QoS描述信息中的策略控制功能网元的QoS信息相同，则可以不执行1707。
1708、会话管理功能网元将新的目标QoS描述信息中的终端设备的目标QoS信息发送给终端设备。相应的，终端设备从会话管理功能网元接收新的目标QoS描述信息中的终端设备的目标QoS信息。
本步骤可参考图16中步骤1614的描述，此处不再赘述。
在执行步骤1708之前，可选地，还包括步骤1705。
1705、会话管理功能网元确定目标QoS描述信息发生改变。
例如，会话管理功能网元确定目标QoS描述信息中的终端设备的目标QoS信息发生改变。如果会话管理功能网元确定目标QoS描述信息中终端设备的QoS信息与新的目标QoS描述信息中的终端设备的QoS信息不同，执行步骤1708。如果会话管理功能网元确定目标QoS描述信息中终端设备的QoS信息与新的目标QoS描述信息中的终端设备的QoS信息相同，则可以不执行1708。
1709、会话管理功能网元将新的目标QoS描述信息中的业务服务器的目标QoS信息发送给业务服务器。相应的，业务服务器从会话管理功能网元接收新的目标QoS描述信息中的业务服务器的目标QoS信息。
本步骤可参考图16中步骤1615的描述，此处不再赘述。
在执行步骤1709之前，可选地，还包括步骤1705。
1705、会话管理功能网元确定目标QoS描述信息发生改变。
例如，会话管理功能网元确定目标QoS描述信息中的业务服务器的目标QoS信息发生改变。如果会话管理功能网元确定目标QoS描述信息中业务服务器的QoS信息与新的目标QoS描述信息中的业务服务器的QoS信息不同，执行步骤1709。如果会话管理功能网元确定目标QoS描述信息中业务服务器的QoS信息与新的目标QoS描述信息中的业务服务器的QoS信息相同，则可以不执行1709。
在一种可能的设计中，当接入网网元的QoS信息中包含无线接入制式类型要求时，在步骤1702后，可选地，执行步骤1702A。

例如，接入网网元判断目标QoS描述信息中无线接入类型要求是否发生改变具体可判断终端设备当前所在小区的无线接入类型与所述重新确定的接入网网元目标QoS信息中包含的无线接入类型要求是否不同，不同则确定为改变，相同则确定为不变。
若不变，则执行步骤1703至1709；若发生改变，则执行步骤1710。
1710、接入网网元触发将所述终端设备从当前所在小区切换或重定向至目标小区，所述目标小区的无线接入类型与所述重新确定的接入网网元目标QoS信息中包含的无线接入类型要求相同。
本申请实施例中提供了一种因接入网的参数发生变化而导致网络重新选择QoS参数的机制，保证了网络能够根据不同的无线接入网环境灵活地使用数据分析网元提供的多套QoS描述信息中的一种，从而保证了业务的服务质量。

1801、会话管理功能网元确定用户面功能网元不再满足目标QoS描述信息。
例如，会话管理功能网元确定用户面功能网元不再满足目标QoS描述信息中的用户面功能网元的目标QoS信息。本发明实施例对用户面功能网元不再满足目标QoS描述信息的原因不做限定。例如，如用户面功能网元的参数发生变化，导致用户面功能网元为单业务、单用户分配的资源数发生变化；或者业务终端在不同的用户面功能网元之间切换，新 的目标用户面功能网元无法满足已经选择的目标QoS描述信息中对用户面功能网元的QoS参数要求。
在一种可能的设计中，步骤1801可以在图16中步骤1612之后执行，或者，步骤1801也可以在图17的步骤1706之后执行。
在步骤1801之后，会话管理功能网元通过执行步骤1802至1811，可以根据至少一条第一QoS描述信息重新确定至少一条接入网网元的QoS信息，然后将重新确定的至少一条接入网网元的QoS信息发送给接入网网元，并从接入网重新接收接入网网元重新确定的接入网网元的目标QoS信息。其中，会话管理功能网元接收至少一条第一QoS描述信息的过程可以参考步骤1605的描述。步骤1802至1811可参考图16中步骤1606至1615的描述，此处不再赘述。本申请实施例中提供了一种因核心网的参数发生变化而导致网络重新选择QoS参数的机制，保证了网络能够根据不同的核心网环境灵活地使用数据分析网元提供的多套QoS描述信息中的一种，从而保证了业务的服务质量。
