随着通信技术的发展，如何提高数据流的服务质量成了亟待解决的问题。
在现有技术中，当无线接入网对数据流的保证比特率不能满足或者可以重新满足时，可以向核心网设备发送通知消息，核心网设备可能采取调整为备选保证比特率等方案对数据流的服务质量进行调整。
然而，发明人在实现本申请的过程中，发现通过上述现有技术中的方式至少存在以下问题：核心网设备对数据流的服务质量的调整的准确性偏低。
发明内容
为解决上述技术问题，本申请实施例提供了一种通信方法、设备及存储介质。
第一方面，本申请实施例提供了一种通信方法，应用于应用功能设备，所述方法包括：

值得说明的是，在本实施例中，应用功能设备接收到的通知消息中包括网络特征信息，而根据网络特征信息可以确定无线接入网设备无法满足保证比特率的根本原因，因此，当应用功能设备根据网络特征信息确定对数据流的服务质量进行调整的调整策略，并根据调整策略对数据流的服务质量进行调整，或者指示用户设备根据调整策略对数据流的服务质量进行调整时，可以实现有针对性的对数据流的服务质量进行调整，进而提高调整的灵活性、准确性及可靠性的技术效果。
在一些实施例中，该方法还包括：
收发调整后的数据流。
在一些实施例中，所述网络特征信息包括：质量参数信息和/或网络事件信息，其中，所述网络事件信息用于指示所述无线空口的网络无法满足预设的网络需求。

5G系统中的接入网可以是无线接入网(radio access network，(R)AN)，可以用于实现无线物理层功能、无线资源管理、无线接入控制以及移动性管理等功能。如，5G系统中的(R)AN设备可以由多个5G-(R)AN节点组成，该5G-(R)AN节点可以包括：非3GPP的接入网络如WiFi网络的接入点(access point，AP)、下一代基站(可统称为新一代无线接入网节点(NG-RAN node)，其中，下一代基站包括新空口基站(NR nodeB，gNB)、新一代演进型基站(NG-eNB)、中心单元(central unit，CU)和分布式单元(distributed unit，DU)分离形态的gNB等)、收发点(transmission receive point，TRP)、传输点(transmission point，TP)或其它节点。
如图2所示，5G核心网(5G core/new generation core，5GC/NGC)包括接入和移动性管理功能(Access and Mobility Management Function，AMF)设备、会话边界控制器(Session Border Controller，SBC)、会话管理功能(Session Management Function，SMF)设备、用户面功能(User Plane Function，UPF)设备、鉴权服务器功能(Authentication Server Function，AUSF)设备、策略控制功能(Policy Control Function，PCF)设备、应用功能(Application Function，AF)设备、统一数据管理功能(unified data management，UDM)设备、网络切片选择功能(Network Slice Selection Function，NSSF)设备等多个功能单元。

上述内容主要对本申请中可能涉及到的设备或设备进行说明。需要理解的是，图2所示的网络架构仅作为示例性说明，并不对本申请可适用的通信系统的网络架构构成限定。本申请可适用的通信系统中还可以包括其它设备或设备，本申请不在一一列举。并且，本申请可适用的通信系统中各设备或设备之间的连接形式既可以采用图2所示的基于参考点的形式，还可以是基于服务化接口的形式。此外，本申请可适用的通信系统还可以分为非漫游场景、以及漫游场景，其中，漫游场景可以进一步划分为本地疏导(local breakout，)场景、以及归属路由(home routed)场景。这些通信场景下通信系统的网络架构可能有所区别，但均可适用于本申请实施例中。
目前，在3GPP R16协议标准中，定义了通知控制(Notification Control)机制，用来在RAN无法保证流保证比特率(Guaranteed Flow Bit Rate，GFBR)时可以上报通知(Notify)消息。
且，在3GPP TS 23.502定义了分组数据单元PDU会话修改(Session Modification)流程：
如果在流保证比特率(Guaranteed Bit Rate，GBR)QoS Flow下发时设置了Notification Control，则RAN可以发送N2消息给SMF，指示RAN对于QoS Flow的GBR不能满足或者可以重新满足。
同时RAN还可能携带当前可以支持的与QoS参数值相匹配的备选QoS Profile(PCF在建专载时下发)。
如果PCF订阅了Notification事件，SMF会针对每个PCC Rule上报此事件给PCF。
且，在3GPP TS 38.413定义了RAN上报通知(Nofity)消息流程，并在流程中定义了上报Nofity消息中携带的IE内容，主要包括相关的流列表及上报的原因。如，可能上报QoS流释放列表、QoS流Notify列表、Notification原因值，及UE的位置信息等。
在相关技术中，当应用功能设备(如会话边界控制器SBC，又如应用功能AF网元，代理呼叫会话控制功能设备)接收到RAN设备上报的Nofity消息时，可以根据预先设置的本地策略进行处理，如修改或删除该GBR QoS flow；又如，应用功能设备指示PCF设备修改或者删除该GBR QoS flow，等等。
然后通过上述相关技术中的方案，应用功能设备的处理方式缺乏针对性，从而使得处理结果的准确性和可靠性不高的问题。
本申请的发明人在经过创造性地劳动之后，得到了本申请的发明构思：应用功能设备对无线空口的网络特征信息进行获取，并基于网络特征信息针对性的采取优化措施。
下面以具体地实施例对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图，对本申请的实施例进行描述。
第一方面，本申请实施例提供了一种适用于上述网络构架的通信方法。
请参阅图3，图3为本申请一个实施例的通信方法的流程示意图。
如图3所示，该方法包括：
S101：应用功能设备接收无线接入网设备上报的通知消息，通知消息用于指示无线接入网设备无法满足用户设备的数据流的保证比特率，通知消息中包括无线空口的网络特征信息。
其中，数据流可以包括：呼叫请求对应的数据流和数据请求对应的数据流。
若数据流为呼叫请求对应的数据流，则用户设备可以理解为主叫用户对应的设备，且数据流可以理解为，主叫用户通过该用户设备依次经过无线接入网设备和应用功能设备向被叫用户发起呼叫请求时产生的数据流，当然，数据流也可以理解为被叫用户基于主叫用户的呼叫请求反馈的数据流。
若数据流为数据请求对应的数据流，则数据流可以理解为，用户设备依次经过无线接入网设备和应用功能设备获取各网络提供的数据时产生的数据流，当然，数据流也可以理解为应用功能设备从各网络获取并反馈给用户设备的数据流。
其中，保证比特率是服务质量(Quality of Service，QoS)中的参数，可以用于表征一个无线空口承载能够保证提供的比特速率。
例如，在本实施例中，用户设备与无线接入网通过无线空口(Air Interface)互相连接，无线空口为无线接入网设备所在空口，且无线空口可以理解为无线接入网设备和用户设备之间的无线传输规范，它可以定义每个无线信道的使用频率、带宽、接入时机、编码方法以及越区切换等。
其中，网路特征信息可以理解为无线空口基于无线传输规范将数据流传输至无线接入网设备时，无线空口传输数据流时的质量参数信息和/或网络事件信息。
示例性地，质量参数信息可以理解为无线空口传输数据流时的与传输信号质量相关的信息(即信号质量参数信息)和/无线空口传输数据流时的与传输信道质量相关的信息(即信道质量参数信息)。
网络事件信息可以理解为用于指示无线空口的网络无法满足传输数据流的预设的网络需求的信息，如高负荷事件信息，即无线空口的网络无法满足传输数据流的负荷需求的信息；又如，高干扰事件信息，即无线空口的网络无法满足传输数据流的干扰需求的信息；再如，弱覆盖事件信息，即无线空口的网络无法满足传输数据流的覆盖需求的信息，等等，此处不再一一列举。
基于上述分析可知，在相关技术中，当无线接入网设备无法满足用户设备的数据流的保证比特率时，可以向应用功能设备发送通知消息，而在本申请实施例中，在通知消息中引入了网络特征信息，且通过引入网络特征信息，可以使得应用功能设备可以基于网络特征信息确定无线接入网设备无法满足保证比特率的原因，从而便于后续应用功能设备针对性的生成对数据流的服务质量进行调整的调整策略，进而实现对数据流的服务质量的调整的可靠性和准确性的技术效果。
S102：应用功能设备根据网络特征信息生成用于对数据流的服务质量进行调整的调整策略。
S103：应用功能设备对数据流执行调整策略，或者，向用户设备发送指示消息，指示消息用于指示用户设备基于调整策略对数据流的服务质量进行调整。
也就是说，在本实施例中，可以由应用功能设备执行调整策略，以便对数据流的服务质量进行调整，也可以由应用功能设备向用户设备发送指示消息，以便由用户设备执行调整策略，即由用户设备对数据流的服务质量进行调整。
在一些实施例中，应用功能设备还可以收发调整后的数据流。
例如，应用功能设备向无线接入网设备发送调整后的数据流，或者，应用功能设备接收用户设备经过无线接入网设备发送的，由用户设备调整后的数据流。
为使读者更加深刻地理解本申请实施例的方案，现以用户设备执行调整策略为例，对本申请实施例的通信方法进行详细地阐述。其中，图4为本申请另一实施例的通信方法的流程示意图。
如图4所示，该方法包括：
S201：用户设备向无线接入网设备发送数据流。
相应地，无线接入网设备接收用户设备发送的数据流。
其中，关于数据流的描述可以参见上述示例，此处不再赘述。
S202：当无线接入网设备无法满足数据流的保证比特率(Guaranteed Bit Rate，GBR)时，无线接入网设备获取无线空口的网络特征信息。
其中，关于保证比特率和无线空口的描述可以参见上述示例，此处不再赘述。
且基于上述分析可知，网路特征信息可以理解为无线空口基于无线传输规范将数据流传输至无线接入网设备时，无线空口传输数据流时的与传输信号质量相关的信息(即信号质量参数信息)和/无线空口传输数据流时的与传输信道质量相关的信息(即信道质量参数信息)。在本实施例中，以网络特征信息包括信号质量参数信息和信道质量参数信息为例，对通信方法进行示范性地阐述。
也就是说，网络特征信息可以从传输数据流时的信号的质量的维度进行理解；也可以从传输数据流时，用于传输数据流的信道的质量的维度进行理解。而当结合信号质量和信道质量的维度获取网络特征信息时，可以确保获取到的网络特征信息的全面性和可靠性。
其中，对信号质量参数信息的描述如下：
在一种可能实现的方案中，信号质量参数信息可以包括信号干扰噪声比(Signal to Interference plus Noise Ratio，SINR)相关的信息，如信号干扰噪声比，又如信号干扰噪声比的等级。
其中，信号干扰噪声比相关的信息可以理解为信号被干扰的情况，在本实施例中，信号干扰噪声比相关的信息可以理解为用户设备通过无线空口将数据流传输至无线接入网设备的过程中，数据流的信号被其他信号干扰的严重程度，且可以通过信号干扰噪声比的方式表达，也可以通过信号干扰噪声比的等级的方式表达。
当通过信号干扰噪声比的等级的方式表达时，可以由无线接入网设备或者空中接口设置信号干扰噪声比与等级之间的映射关系，而当确定出信号干扰噪声比时，可以基于该映射关系确定与信号干扰噪声比对应的等级。例如，信号干扰噪声比越大，则信号干扰噪声 比对应的等级越高；又如，信号干扰噪声比越大，则信号干扰噪声比对应的等级越低。
在另一种可能实现的方案中，信号质量参数信息可以包括参考信号接收功率(Reference Signal Received Power，RSRP)相关的信息，如参考信号接收功率，又如参考信号接收功率的等级。
其中，参考信号接收功率可以理解为接收到的信号功率的平均值，在本实施例中，参考信号接收功率可以理解为用户设备通过无线空口将数据流传输至无线接入网设备的过程中，无线空口接收到的数据流的信号功率的平均值，且参考信号接收功率相关的信息可以通过参考信号接收功率的方式表达，也可以通过参考信号接收功率的等级表达。
同理，当通过参考信号接收功率的等级的方式表达时，可以由无线接入网设备或者空中接口设置参考信号接收功率与等级之间的映射关系，而当确定出参考信号接收功率时，可以基于该映射关系确定与参考信号接收功率对应的等级。例如，参考信号接收功率越大，则参考信号接收功率对应的等级越高；又如，参考信号接收功率越大，则参考信号接收功率对应的等级越低。
其中，对信道质量参数信息的描述如下：
信道质量参数信息可以包括信道质量相关的信息，如信道利用率，又如信道利用率的等级。
同理，当信道质量参数信息包括信道利用率的等级时，可以由无线接入网设备或者空中接口设置信道利用率与等级之间的映射关系，而当确定出信道利用率时，可以基于该映射关系确定与信道利用率对应的等级。例如，信道利用率越大，则信道利用率对应的等级越高；又如，信道利用率越大，则信道利用率对应的等级越低。
其中，信道利用率的等级包括：物理下行控制信道(Physical Downlink Control Channel，PDCCH)利用率的等级、物理下行共享信道(Physical Downlink Shared Channel，PDSCH)利用率的等级、物理上行共享信道(Physical Uplink Shared Channel，PUSCH)利用率的等级及信道利用率综合等级中的至少一种。
其中，信道利用率综合等级可以理解为各信道的利用率相结合时对应的等级。例如，可以计算各信道的利用率的综合利用率，并设置综合利用率与等级之间的映射关系；也可以设置各信道的权重系数，并基于各信道的利用率和各自对应的权重信息，确定信道利用率综合等级。
S203：无线接入网设备向应用功能设备发送包括网络特征信息的通知消息。
相应的，应用功能设备接收无线接入网设备发送的包括网络特征信息的通知消息。
值得说明的是，若网络特征信息通过信号干扰噪声比的等级、参考信号接收功率的等级及信道利用率的等级的方式表达时，可以避免无线接入网设备向应用功能设备发送具体参数值(如信号干扰噪声比、参考信号接收功率及信道利用率)时，造成的参数值泄露而引发的安全性问题，从而实现数据传输的安全性的技术效果。
S204：若网络特征信息包括信号干扰噪声比的等级，且信号干扰噪声比的等级满足预先设置的第一规则，则应用功能设备生成包括第一调整策略的第一指示消息，第一指示消息用于指示用户设备基于第一调整策略对数据流的服务质量进行调整，第一调整策略是指通过生成包括数据流的冗余帧(Redundancy Data，RED)的方式对数据流的服务质量进行调整。
其中，第一规则包括信号干扰噪声比的等级大于预先设置的第一阈值，或者，信号干扰噪声比的等级小于第一阈值。
基于上述分析可知，在一些实施例中，当信号干扰噪声比越大时，则信号干扰噪声比对应的等级越高，则相应的，第一规则包括信号干扰噪声比的等级大于预先设置的第一阈值；而在另一些实施例中，当信号干扰噪声比越大时，则信号干扰噪声比对应的等级越低，则相应的，第一规则可以为信号干扰噪声比的等级小于预先设置的第一阈值。
在本实施例中，以第一规则为信号干扰噪声比的等级大于第一阈值为例，进行示范性地描述，而第一规则为信号干扰噪声比的等级小于第一阈值时的本申请的实现原理与此类似，此处不再赘述。
其中，第一阈值可以由应用功能设备基于需求、历史记录及实验等进行设置，本实施例不做限定。
例如，现以应用功能设备基于历史记录为例对第一阈值进行设置地描述如下：
历史记录可以用于体现信号干扰噪声比的等级与数据流的服务质量之间的映射关系，当基于历史记录确定信号干扰噪声比的等级为某值时，数据流的服务质量偏低，无法满足呼叫请求的需求，如无法满足通话质量，则将该值设置为第一阈值。
相应的，该步骤可以具体包括：应用功能设备判断网络特征信息中是否包括信号干扰噪声比的等级，若是(即网络特征信息中包括信号干扰噪声比的等级)，则应用功能设备判断信号干扰噪声比的等级是否大于第一阈值，若是(即信号干扰噪声比的等级大于第一阈值)，则应用功能设备生成包括第一调整策略的第一指示消息。而若网络特征信息中不包括信号干扰噪声比的等级，或者信号干扰噪声比的等级小于第一阈值时，则应用功能设备可以执行S208。
S205：应用功能设备向用户设备发送第一指示消息。
相应的，用户设备接收应用功能设备发送的第一指示消息。
S206：用户设备根据第一指示消息生成包括数据流的冗余帧。
S207：用户设备向无线接入网设备发送包括数据流的冗余帧。
相应的，无线接入网设备接收用户设备发送的包括数据流的冗余帧。
也就是说，用户设备在接收到应用功能设备发送的第一指示消息之后，可以生成多帧包括数据流的数据帧，从而可以避免因用户设备在向无线接入网设备发送数据流时，因数据流被其他信号干扰而造成的数据流丢包和被阻塞等问题，从而实现数据流传输的可靠性和稳定性。
应该理解的是，无线接入网在接收到用户设备发送的包括数据流的冗余帧之后，可以向应用功能设备发送包括数据流的冗余帧，而应用功能设备可以将包括数据流的冗余帧发送至相应的网络，从而完成与呼叫请求对应的呼叫业务，或者完成与数据请求对应的数据业务。
S208：若网络特征信息包括参考信号接收功率的等级，且参考信号接收功率的等级满足预先设置的第二规则，则应用功能设备生成包括第二调整策略的第二指示消息，第二指示消息用于指示用户设备基于第二调整策略对数据流的服务质量进行调整，第二调整策略是指通过降低数据流的编解码速率(Codec Mode Request，MR)的方式对数据流的服务质量进行调整。
其中，第二规则包括参考信号接收功率的等级大于预先设置的第二阈值，或者，参考信号接收功率的等级小于第二阈值。
基于上述分析可知，在一些实施例中，当参考信号接收功率越大，则参考信号接收功率对应的等级越高，则相应的，第二规则包括参考信号接收功率的等级小于第二阈值；而在另一些实施例中，当参考信号接收功率越大时，则参考信号接收功率对应的等级越低，则相应的，第二规则可以为参考信号接收功率的等级大于第二阈值。
同理，在本实施例中，以第二规则为参考信号接收功率的等级小于第二阈值为例，进行示范性地描述，而第二规则为参考信号接收功率的等级大于第二阈值时的本申请的实现原理与此类似，此处不再赘述。
同理，第二阈值可以由应用功能设备基于需求、历史记录及实验等进行设置，本实施例不做限定，且应用功能设备设置第二阈值的原理可以参见应用功能设备设置第一阈值的描述，此处不再赘述。
相应的，该步骤可以具体包括：应用功能设备判断网络特征信息中是否包括参考信号接收功率的等级，若是(即网络特征信息中包括参考信号接收功率的等级)，则应用功能设备判断参考信号接收功率的等级是否大于第二阈值，若是(即参考信号接收功率的等级大于第二阈值)，则应用功能设备生成包括第二调整策略的第二指示消息。而若网络特征信息中不包括参考信号接收功率的等级，或者参考信号接收功率的等级小于第二阈值时，则应用功能设备可以执行S212。
S209：应用功能设备向用户设备发送第二指示消息。
相应的，用户设备接收应用功能设备发送的第二指示消息。
S210：用户设备根据第二指示消息降低数据流的编码速率。
S211：用户设备向无线接入网设备发送降低了编码速率的数据流。
相应的，无线接入网设备接收用户设备发送的降低了编码速率的数据流。
值得说明的是，编码速率可以理解为用户设备对数据流进行编码的速率，不同的编码速率使得用户设备传输数据流时的增益不同，即不同的编码速度使得用户设备传输数据流的覆盖范围不同。而在本实施例中，用户设备对数据流的编码速率进行降低处理，可以提高用户设备传输数据流时的覆盖范围，从而提高数据流传输的可靠性。
同理，无线接入网在接收到用户设备发送的降低了编码速率的数据流之后，可以向应用功能设备发送降低了编码速率的数据流，而应用功能设备可以将降低了编码速率的数据流发送至相应的网络，从而完成与呼叫请求对应的呼叫业务，或者完成与数据请求对应的数据业务。
S212：若网络特征信息包括信道利用率的等级，且信道利用率的等级满足预先设置的第三规则，则应用功能设备生成包括第三调整策略的第三指示消息，第三指示消息用于指示用户设备基于第三调整策略对数据流的服务质量进行调整，第三调整策略是指通过降低数据流的编解码速率和对数据流进行多帧聚合(Frame Aggregation，AGG)的方式对数据流的服务质量进行调整。
其中，第三规则包括信道利用率的等级大于预先设置的第三阈值，或者，信道利用率的等级小于第三阈值。
基于上述分析可知，在一些实施例中，信道利用率越大，则信道利用率对应的等级越 高，则相应的，第三规则包括信道利用率的等级大于第三阈值；而在另一些实施例中，当信道利用率越大时，则信道利用率对应的等级越低，则相应的，第三规则可以为信道利用率的等级小于第三阈值。
同理，在本实施例中，以第三规则为信道利用率的等级大于第三阈值为例，进行示范性地描述，而第三规则为信道利用率的等级小于第三阈值时的本申请的实现原理与此类似，此处不再赘述。
同理，第三阈值可以由应用功能设备基于需求、历史记录及实验等进行设置，本实施例不做限定，且应用功能设备设置第三阈值的原理可以参见应用功能设备设置第一阈值的描述，此处不再赘述。
相应的，该步骤可以具体包括：应用功能设备判断网络特征信息中是否包括信道利用率的等级，若是(即网络特征信息中包括信道利用率的等级)，则应用功能设备判断信道利用率的等级是否大于第三阈值，若是(即信道利用率的等级大于第三阈值)，则应用功能设备生成包括第三调整策略的第三指示消息。
S213：应用功能设备向用户设备发送第三指示消息。
相应的，用户设备接收应用功能设备发送的第三指示消息。
S214：用户设备根据第三指示消息生降低数据流的编码速率，且对降低编码速率后的数据流进行多帧聚合。
S215：用户设备向无线接入网设备发送多帧聚合后的数据流。
相应的，无线接入网设备接收用户设备发送的多帧聚合后的数据流。
其中，关于降低数据流的编码速率的描述可以参见上述描述，此处不再赘述。
值得说明的是，多帧聚合可以理解为将包括数据流的多帧数据聚合在一个数据包中，可以降低用户设备向无线接入网设备传输包括数据流的数据包的频率，从而实现节省交互资源(如宽带)的技术效果。
同理，无线接入网在接收到用户设备发送的多帧聚合后的数据流之后，可以向应用功能设备发送多帧聚合后的数据流，而应用功能设备可以将多帧聚合后的数据流发送至相应的网络，从而完成与呼叫请求对应的呼叫业务，或者完成与数据请求对应的数据业务。
基于上述分析可知，在一些实施例中，当应用功能设备接收无线接入网设备发送的包括网络特征信息的通知消息时，应用功能设备基于网络特征信息的具体内容(如信号质量参数信息和信道质量参数信息)生成包括相应的调整策略的指示消息(如包括第一调整策略的第一指示消息、包括第二调整策略的第二指示消息及包括第三调整策略的第三指示消息)，并向用户设备发送指示消息，用户设备根据执行指示消息中携带的调整策略，从而实现针对性的调整数据流的服务质量，进而实现调整数据流的服务质量的灵活性，且实现数据传输的准确性和可靠性的技术效果。
在另一些实施例中，可以由应用功能设备对数据流的服务质量进行调整，现结合图5进行详细地阐述。
如图5所示，该方法包括：
S301：应用功能设备向无线接入网设备发送数据流。
在上述实施例中，数据流可以理解为上行数据，在本实施例中，数据流可以理解为下行数据，如数据流为应用功能设备向用户设备反馈数据请求的数据流，又如，数据流为应 用功能设备向用户设备反馈呼叫请求的数据流(如被叫用户基于用户设备发起的呼叫请求的数据流)。
S302：当无线接入网设备无法满足数据流的保证比特率时，无线接入网设备获取无线空口的网络特征信息。

相应的，应用功能设备接收无线接入网设备发送的包括网络特征信息的通知消息。
同理，关于S303的描述可以参见S203，此处不再赘述。
S304：若网络特征信息包括信号干扰噪声比的等级，且信号干扰噪声比的等级大于预先设置的第一阈值，则应用功能设备通过生成包括数据流的冗余帧的方式对数据流的服务质量进行调整。
其中，关于应用功能设备设置第一阈值的原理可以上述实施例中，应用功能设备设置第一阈值的原理，关于应用功能设备通过生成包括数据流的冗余帧的方式对数据流的服务质量进行调整的原理，可以参见上述实施例中用户设备根据第一指示消息对数据流的服务质量进行调整的原理，此处不再赘述。
值得说明的是，该步骤可以具体包括：应用功能设备判断网络特征信息中是否包括信号干扰噪声比的等级，若是(即网络特征信息中包括信号干扰噪声比的等级)，则应用功能设备判断信号干扰噪声比的等级是否大于第一阈值，若是(即信号干扰噪声比的等级大于第一阈值)，则应用功能设备通过生成包括数据流的冗余帧的方式对数据流的服务质量进行调整。

示例性地，质量参数信息包括但不限于负荷参数、覆盖参数以及干扰参数。
S603：无线接入网设备根据质量参数信息、事件类型以及网络质量阈值生成网络事件信息。
其中，事件类型可以表征无线空口的网络无法满足网络需求的类型，如若无线空口的网络无法满足网络负荷需求的类型，则可以将该事件类型称为负荷事件类型，同理，若无线空口的网络无法满足网络干扰需求的类型，则可以将该事件类型称为干扰事件类型，以此类推，此处不再一一列举。
事件类型与网络质量阈值之间存在对应关系，即两个不同事件类型各自对应的网络质量阈值可能不同，如负荷事件类型对应的网络质量阈值与干扰事件类型的网络质量阈值不同。
该步骤具体可以包括：无线接入网设备针对任一事件类型，判断质量参数信息是否达到任一事件类型对应的网络质量阈值，若达到，则生成网络事件信息。
值得说明地是，在本实施例中，针对不同的事件类型，无线接入网设备判断质量参数信息是否达到事件类型对应的网络质量阈值，可能为大于或等于的达到，也可能为小于或等于的达到。
例如，针对干扰事件类型，达到可以理解为大于或等于，即无线接入网设备判断质量参数信息是否大于或等于干扰事件类型对应的网络质量阈值，如果是，则生成网络事件信息，且该网络事件信息可以用于指示无线空口的网络无法满足网络干扰需求。

例如，订阅事件可以通过事件类型、网络质量阈值、以及大于关系表示，如针对干扰事件的订阅事件，订阅事件可以通过SINR＞0.3表示，其中，SINR用于指示事件类型，且具体为干扰事件类型，0.3用于指示网络质量阈值，且具体用于指示干扰质量阈值，＞用于指示大小关系，且具体用于指示干扰事件类型的干扰质量阈值大于0.3。例如，若无线空口的网络的干扰噪声比大于干扰质量阈值0.3，则无线接入网设备生成网络事件信息，且该网络事件信息用于指示无线空口的网络无法满足干扰需求。
又如，订阅事件还可以通过事件类型和网络质量阈值表示，如针对干扰事件的订阅事件，订阅事件可以通过SINR和0.3表示，其中，SINR用于指示事件类型，且具体为干扰事件类型，0.3用于指示网络质量阈值，且具体用于指示干扰质量阈值。例如，若无线空口的网络的干扰噪声比大于干扰质量阈值0.3，则无线接入网设备生成网络事件信息，且该网络事件信息用于指示无线空口的网络无法满足干扰需求。
具体地，如图9所示，无线接入网设备NG-RAN(图9中以NG-RAN表示)触发应用功能设备AF(图9中以AF表示)执行策略调整的方法可以包括：

另一个示例中，无线接入网设备可以与应用功能设备针对事件类型和网络质量阈值进行协商，并对协商的事件类型和网络质量阈值进行存储。
值得说明的是，在一些实施例中，网络事件信息可以包括事件类型信息，且事件类型信息用于指示事件类型的质量参数信息达到网络质量阈值。
例如，事件类型包括：干扰事件类型和覆盖事件类型，相应地，网络质量阈值包括：与干扰事件类型对应的网络质量阈值(下文称为干扰质量阈值)，与覆盖事件类型对应的网络质量阈值(下文称为覆盖质量阈值)，则若无线接入网设备确定出质量参数信息中的覆盖质量参数达到覆盖质量阈值，则无线接入网生成事件类型信息，且该事件类型信息用于指示覆盖事件类型的质量参数信息(即覆盖质量参数)达到网络质量阈值(即覆盖质量阈值)。
示例性地，不同的事件类型对应不用的标识(QFI标识)，则无线接入网设备生成的事件类型信息可以为与事件类型对应的QFI标识。例如，针对覆盖事件类型的事件类型信息，事件类型信息可以为覆盖事件类型对应的QFI标识；又如，针对干扰事件类型的事件类型信息，事件类型信息可以为干扰事件类型对应的QFI标识；再如，事件类型信息既可以包括覆盖事件类型对应的QFI标识，也可以包括干扰事件对应的QFI标识，等等，此处不再一一列举。
在另一些实施例中，网络事件信息包括事件类型，以及与事件类型对应的原因值。其中，原因值用于指示质量参数信息达到网络质量阈值。
例如，结合图9所示，S706：若无线接入网设备NG-RAN根据QoS文件和质量参数信息，确定质量参数信息无法满足QoS文件，则生成原因值。
其中，原因值用于指示质量参数信息无法满足据QoS文件。
