如图2所示，本公开实施例提供一种信息处理方法，其中，由第一网络节点执行，所述方法包括：
S1110:：接收第二网络节点发送的PDU集的丢包用量信息。
该第一网络节点可为核心网节点，示例性地，所述第一网络节点可为策略控制功能(Policy Control Function，PCF)。所述第二网络节点同样可为核心网节点。所述第二网络节点可为会话管理功能(Session Management Function，SMF)。
所述第一网络节点和所述第二网络节点为网络中不同的网络节点，也即不同的网络设备。
所述PDU集内可包括一组PDU。该在一组PDU可包括一个或多个PDU。一个所述PDU可为一个数据包。
示例性地，位于一个PDU集的数据包可为具有定关联性的数据包。例如，所述PDU集内的数据包可为同一个视频帧的数据包、或者，具有相互依赖关系的多个视频帧的数据包。又示例性地，PDU集内的数据包可为多模态数据的一个会多个设备的输入数据、一个或多个设备的输出数据等。再示例性地，该PDU集内的数据包可为XR业务的具有关联性的不同类型的数据包。
在本公开实施例中，所述PDU集可为下行PDU集和/或上行PDU集。
所述PDU集内的数据包的丢弃可为任意网络节点的丢包，示例性地，这种数据包的丢弃可以发生在接入网，从而丢弃数据包的网络节点为接入网络节点。当然这种丢包也可以发生在核心网，这种丢弃数据包的网络节点可为前述核心网节点。该核心网节点包括但不限于：用户面功能(User Plane Function，UPF)。
当然此处仅仅是对PDU集内的数据包的举例，具体实现不局限于上述任意一个举例。
所述丢包用量信息可指示PDU集中被丢弃的数据包的数据量。
第二网络节点通过这种丢包用量信息的获取，可以实现对网络传输给终端的用量进行精确统计，和/或根据所述丢包用量信息对终端与PDU集相关的流和/或会话进行更加精确的服务质量(Service of Quality，QoS)的控制。
如图3A所示，本公开实施例提供一种信息处理方法，其中，由第一网络节点执行，所述方法包括：
S1210：接收第二网络节点发送的PDU集的丢包用量信息。
S1220：根据所述丢包用量信息，决策流量限制。
在本公开实施例中，所述第一网络节点可以根据丢包用量信息确定流量限制，该流量限制是针对PDU集的流或者会话的。
示例性地，所述S1220可包括：增强流量限制和/或放松流量限制。
示例性地，若增强流量限制可是进一步精细化PDU集的丢包。放松流量限制可为：基于传输PDU集的网络节点可以放松丢包限制，以便网络节点根据网络拥塞状况和/或数据包传输需求等更加自主的选择丢包。
以上仅仅是对增强流量限制和/或放松流量限制的举例说明，具体实现时不局限于上述举例。
如图3B所示，本公开实施例提供一种信息处理方法，其中，由第一网络节点执行，所述方法包括：
S1310：接收第二网络节点发送的PDU集的丢包用量信息。
S1320：根据所述丢包用量信息，校正计费用量。
此处的计费用量是参与费用核酸的网络流量值。
在本公开实施例中，所述第一网络节点收到丢包用量信息之后，可以校正PDU集的流或者会话的计费用量，从而使得计费更加精确。
如图3C所示，本公开实施例提供一种信息处理方法，其中，由第一网络节点执行，所述方法包括：
S1410：接收第二网络节点发送的PDU集的丢包用量信息。
S1420：根据所述丢包用量信息，决策流量限制；
S1430：根据所述丢包用量信息，校正计费用量。
在一些实施例中，所述第一网络节点接收到所述PDU集的丢包用量信息之后，一边会进行流量限制的决策，另一边会进行计费用量的校正，一方面可以对PDU集的传输可实现更加精确的控制，另一方面实现计费的精确化。
值得注意的是：S1420和S1430没有一定的先后顺序，可以同时执行先执行其中一个再执行另一个。
在另一些实施例中，所述第一网络节点接收到所述PDU集的丢包用量信息之后，若认为丢包用量信息指示的丢包产生的数据量在可接收的范围内，当前的丢包产生的数据量在可接受范围内，无需进行流量限制都可重新决策或者计费用量的校正，则所述第一网络节点仅仅是保存所述丢包用量信息或者甚至删除所述丢包用量信息。
在一些实施例中，如图3D所示，本公开实施例提供一种信息处理方法，其中，由第一网络节点执行，所述方法包括：
S1510：接收第二网络节点根据PDU集的丢包用量信息校正后的计费用量。
在该实施例中，第二网络节点会对PDU集进行丢包用量进行监控，并得到丢包用量信息。在第二网络节点得到丢包用量信息之后，会完成对该PDU集的流或者会话进行计费用量的校正，则此时第一网络节点接收到的是校正之后的计费用量。所述第一网络节点可以根据校正之后的计费用量进行计费即可。第一网络节点接收到校正后的计费用量之后，可以提供计费系统，由计费系统进行精确计费。示例性地，第一网络节点可以发送给计费系统的计费功能(Charging Function，CHF)。
在一些实施例中，所述PDU集涉及的数据级别包括以下至少之一：
业务数据流(Service Data Flow，SDF)；
PDU会话；
一个UE的一个网络切片传输的所有PDU会话。
不同业务会产生不同的业务数据流。
一个PDU会话可以包括一个或多个业务数据流。
一个UE可以订阅使用一个或多个网络切片。由于使用相同网络切片的数据流或PDU会话可能会具有相同的计费情况和流量限制，因此也可以针对单个UE的单个网络切片进行统一丢包用量统计。
总之，在本公开实施例中，针对PDU集的丢包用量信息的统计，可以具有不同的数据级别，以满足不用数据级别统计的需求。当然以上仅仅是针对上述丢包用量信息统计的数据级别的统计举例，具体实现不局限于上述举例。
在一些实施例中，所述根据所述丢包用量信息，决策流量限制，包括：
根据所述丢包用量信息，更新策略信息的策略控制和计费PCC规则。
在本公开实施例中，通过更新PCC规则来实现流量限制的决策的体现。
例如，更新了流量限制，则通过更新后的PCC规则体现这种更新后的流量限制。
在进行PCC规则更新时，可以是对整个策略信息中所有的PCC规则或者部分PCC规则的更新。
示例性地，所述根据所述丢包用量信息，更新所述策略信息包含的策略控制和计费PCC规则，包括：
根据所述丢包用量信息，更新所述PCC规则的服务质量QoS参数；
和/或，
根据所述丢包用量信息，更新所述PCC规则的计费关键字。
例如，针对PDU集的业务数据流或会话的丢包用量信息进行调整，则可以通过更新PCC规则中的QoS参数来实现。又例如，针对PDU集的业务数据流或会话的计费调整，可以通过更新PCC规则的计费关键字。不同的计费关键字可能映射不同的计费规则，从而实现计费规则的更新。
在一些实施例中，所述QoS参数包括以下至少之一：
PDU集延时预算(PDU集Delay Budget，PSDB)；
PDU集错误率(PDU集Error Rate，PSER)；
第一指示信息，用于指示所述PDU集的所有数据包是否均为应用层所需数据包；
第二指示信息，用于指示所述PDU集满足预设条件时是否允许丢包；
所述PDU集优先级。
若PDU集延时预算的不同，网络节点在传输PDU集的数据包时，可以根据对应的时延预算选择特定的带宽或者传输先后优先级来传输数据包。
若PDU集错误率越低，则要求数据包传输过程中的出错控制越好，则同样需要调度对应的网络资源进行传输。
所述第一指示信息，指示了一个PDU集内所有数据包是否均为应用层所需数据包，可以用于网络节点在需要丢弃数据包时可以有选择性的丢包，例如，选择丢弃应用层不需要的数据包。若一个PDU集内所有的数据包都是应用层要的，则网络节点在传输数据包时需要尽可能避免丢包。
第二指示信息，可以指示PDU集内的数据包可以丢弃，但是需要满足一定的条件才可以丢弃。
示例性地，PDU集内的数据包的PSDB大于延时阈值，说明该PDU集的数据包并非紧急数据包，在网络拥塞的瞬间丢弃这种数据包，即便通过重传也可能达到PSDB对应的延时，因此可以丢包，即确认满足所述预设条件。
又示例性地，PDU集内的数据包的实际错误率已大于QoS参数限定的PSER，网络节点继续传输PDU集内的数据包可能就是没有意义了，因此可以认为满足预设条件，并丢包。
总之，上述QoS参数可为PDU集的QoS参数的举例，具体实现是不局限于上述举例。
进一步地，上述QoS参数可以由前述的PCC规则限定。
在一些实施例中，所述根据所述丢包用量信息，决策流量限制，还包括：
根据所述丢包用量信息，允许主动丢包；
或者，
根据所述丢包用量信息，禁止主动丢包。
决策流量限制时，除了根据丢包用量信息确定策略信息，还可以通过直接限制网络节点的行为来实现，例如，直接限制谁允许网络节点主动丢包或者禁止网络节点主动丢包。
此处的网络节点包括但不限于：接入网节点和/或核心网节点。
例如，若允许丢包，则网络节点可以在发生网络拥塞或者发现数据包的错误率高时主动丢弃对应的数据包，而禁止丢包，则网络节点可以在发生网络拥塞或者发现数据包的错误率高时也不允许丢弃对应的数据包。在禁止丢包的场景下，进行数据包传输的网络节点在一些特殊场景下可以丢白，例如，终端设备指示允许丢包或请求丢包或者管理设备的指示允许丢包。
在一些实施例中，若PDU集已丢弃数据包的用量比较大，若继续丢包会影响PDU集的功能时，则可以通过禁止主动丢包，现在网络节点的丢包，从而及时确保PDU集的传输成功率。
在另一些实施例中，若PDU集内有比较多的数据包并非是终端设备的应用层所需要的数据包、当前PDU集丢包用量很小且网络发生拥塞，则通过将禁止主动丢包修改为允许主动丢包，可以使得网络节点丢弃一个或多个PDU集内的数据包。
在一些实施例中，所述根据所述丢包用量信息，更新策略信息，包括：
根据所述丢包用量信息确定大于或等于丢包阈值，根据所述丢包用量信息更新所述策略信息。
即在一些丢包用量信息指示的丢包的数据量大于或等于丢包阈值时，则说明需要更新策略信息，此时第一网络节点根据丢包用量信息更新策略信息，示例性地，更新策略信息的PCC规则的QoS参数和/或计费关键字。
示例性地，所述丢包阈值下至少之一：
丢包用量百分比；
或
丢包用量。
丢包用量百分比可为：PDU集内被丢弃的数据包的数据量，与PDU集内所有数据包的数据量 的比值。
若PDU集内的实际丢包用量百分比大于或等于所述丢包阈值对应的丢包用量百分比，则第一网络节点更新策略信息。
此处的丢包用量可为被丢弃的数据包的数据量，若PDU集内的实际丢包用量大于或等于所述丢包阈值对应的丢包用量，则第一网络节点更新策略信息。
如图4A所示，本公开实施例提供一种信息处理方法，其中，由第二网络节点执行，所述方法包括：
S2110：监控协议数据单元PDU集的丢包用量信息。
所述第二网络节点包括但不限于SMF。
SMF会监控PDU集的丢包用量信息。所述丢包用量信息至少指示PDU集内数据包的丢包用量。

S2310：向所述第三网络节点或者所述接入网节点发送所述触发事件的事件信息；
S2320：接收所述第三网络节点或接入网节点在所述触发事件发生时发送的PDU集的丢包用量信息。
第三网络节点和接入网节点在检测到触发事件发生时才会上报PDU集的丢包用量信息，从而减少不必要的频繁上报。
在一些实施例中，所述监控关键字预先配置在所述第二网络节点上；或者，所述监控关键字由所述第二网络节点从所述第一网络节点接收。
示例性地，终端在订购某些业务的时候，就可以预先配置监控关键字，并将该监控关键字预先配置在第二网络节点。
示例性地，在建立或更新会话或者业务数据流时，第一网络节点将所述监控关键字发送给所述第二网络节点。
第二网络节点在接收到所述监控关键字之后，能够根据所述监控关键字基于业务数据流、PDU会话或者单个UE单个网络切片的所有PDU会话的监控。在一些实施例中，所述方法还包括：
根据所述PCF提供的策略信息、所述第一网络节点的授权信息和/或所述第二网络节点本地的配置信息，确定与所述触发事件相关的丢包阈值。
在一些实施例中，所述触发事件可包括多种，其中有一种触发事件与丢包阈值相关。若触发事件与丢包阈值相关，该丢包阈值可以直接由策略信息指定，也可以是由第二网络节点根据策略信息第、第一网络节点的授权信息和/或第二网络节点本地的配置信息等多个信息中的一个或多个确定出所述丢包阈值。
所述丢包阈值携带在事件信息中发送给第三网络设备和/或第四网络设备之后，第三网络节点或第三网络节点在根据PDU集丢弃的数据包的数据量统计达到所述丢包阈值，则第二网络节点将会接收到所述第三网络节点或接入网节点发送的丢包用量信息。
如图4D所示，本公开实施例中实施例提供一种信息处理方法，由第二网络节点执行，所述方法包括：
S2410：监控协议数据单元PDU集的丢包用量信息；

S3120：将监控的所述丢包用量信息提供给第二网络节点。
此处的第三网络节点包括但不限于UPF等。

第三网络节点获取到丢包用量信息之后，并将丢包用量信息提交给第二网络节点，以便第二网络节点根据丢包用量信息对PDU集的数据流和/或PDU会话进行流量限制和/或计费校正等。
如图5B所示，本公开实施例提供一种信息处理方法，由第三网络节点执行，所述方法包括：
S3210：从接入网节点接收所述PDU集的丢包用量信息；
S3310：将监控的所述丢包用量信息提供给第二网络节点。
在本公开实施例中，接入网节点丢弃了数据包，就会针对每一个PDU集统计出丢弃的数据量，从而得到所述丢包用量信息，并将所述丢包用量信息发送给第三网络节点，因而第三网络节点会收到接入网节点提供的丢包用量信息。

在本公开实施例中，，接入网节点自身不统计丢包用量信息，而是将丢弃的数据包(也即PDU)返回给第三网络节点，如此，第三网络节点可以根据返回的数据包，自行进行丢包用量的统计。
在一些实施例中，所述将监控的所述丢包用量信息提供给第二网络节点，包括：
所述丢包用量信息满足触发事件，向所述第二网络节点发送报告，其中，所述报告包括所述丢包用量信息。

第三网节点可预先从所述第二网络节点接收所述事件信息，如此，根据事件信息可以知晓触发事件和/或丢包阈值等。
在一些实施例中，所述方法还包括：
根据PDU集信息，确定所述第二网络设备接收的数据包属于同一个PDU集的数据包。
在进行PDU集的丢包用量统计时，首先需要当前接收到的数据包是否属于同一个□□□内。具体如何识别，可以根据PDU集信息来识别。
示例性地，所述第三网络节点可以根据N4规则和本地配置得到所述PDU集信息。
示例性地，所述PDU集信息包括：PDU集内信息和/或PDU集间信息。

在一些实施例中，所述PDU集间信息，包括指示以下至少之一：
重要指示信息，指示对应PDU集的重要性；
独立指示信息，指示所述PDU集是否依赖其他PDU集。
在一个实施例中，针对重要的PDU集设置有重要指示信息，针对不重要的PDU集不设置有重要指示信息。
在另一个实施例中，每一个PDU集都可以设置一个重要指示信息，重要指示信息的具体内容表明PDU集的重要性，此时所述重要指示信息可包括：表征重要性的等级信息。
所述独立指示信息可用于指示一个PDU集是否依赖其他PDU集。例如，若一个PDU集没有一个数据包需要依赖其他PDU集内的数据包才能解码，则该PDU集可为独立PDU集。若一个PDU集至少存在一个数据包需要依赖其他PDU集内的数据包才能解码，则该PDU集需要依赖其他PDU集。而这种PDU集之间的依赖性，可以由所述独立指示信息来表示。
在一些实施例中，所述根据PDU集信息，确定属于同一个PDU集的数据包，包括：
根据所述PDU集信息以及数据包的包头和/或流特征，确定对应数据包是否属于所述PDU集的数据包。
在本公开实施例中，根据PDU集信息和数据包的包头□或流特征，确定每一个经过第三网络节点的数据包是否属于一个PDU集内的数据包。
示例性地，数据包的包头包括一个或多个字段，这些字段指示数据包的类型和/或流特征。例如，该包头内包括指示数据包所使用传输协议的字段。根据该传输协议的字段能够，确定第三网络设备接收到的数据包是否属于PDU集的数据包。
再例如根据包头的类型，确定第三网络节点接收的数据包是否属于PDU集。例如，不同类型的包头具有不同的数据格式，因此可以根据包头的数据格式确定第三网络设备接收到数据包是否属于PDU集。

该接入网节点可为eNB和/或gNB等接入网节点。
在本公开实施例中，接入网节点自身统计丢包用量数据，则会根据自身丢弃的数据包进行数据量统计，得到所述丢包用量信息。
若接入网节点自身不进行丢包用量统计，则会将自身丢弃的数据包返回给第三网络节点或第二网络节点，由第三网络节点或第二网络节点进行PDU集的丢包用量信息统计。为了区分上行数据包，接入网节点会对被自身丢弃的数据包增加丢包标记，方便第三网络节点或第二网络节点根据丢包比较进行丢包用量信息的统计。
在一些实施例中，所述向第二网络节点或第三网络节点，□发送协议数据单元PDU集被丢弃的数据包或者丢包用量信息，包括：
根据触发事件或丢包阈值的事件信息，向第二网络节点或第三网络节点，发送协议数据单元PDU集被丢弃的数据包或者丢包用量信息。
在一些实施例中，接入网节点可以实时上报丢包用量信息或者被丢弃的数据包。在本公开实施 例中为了减少不必要的上报，会在检测到触发事件才上报所述丢包用量或者被丢弃的数据包；或者在检测到丢包用量达到所述丢包阈值时，才上报所述丢包用量信息或者返回被丢弃的数据包。
在一些实施例中，所述方法还包括：
从所述第二网络节点或第三网络节点接收事件信息，其中，所述事件信息，用于指示所述触发事件。
在统计丢包用量信息或者检测丢弃的数据包之前，还会从第二网络节点或第三网络节点接收所述事件信息，以便根据所述事件信息确定出所述触发事件和/或丢包阈值。
在一些实施例中，所述方法还包括：
从所述第三网络节点接收PDU集信息；
根据所述PDU集信息，确定所述第四网络设备接收的数据包属于同一个PDU集的数据包。
在本公开实施例中，所述接入网节点还会接收所述PDU集信息，从而方便根据所述PDU集识别PDU集的数据包。
在一些实施例中，所述PDU集信息包括：PDU集内信息和/或PDU集间信息。
在另一些实施例中，所述PDU集内信息包括：以下至少之一：
PDU集序列号；

在一些实施例中，所述根据所述PDU集信息，确定所述第四网络设备接收的数据包属于同一个PDU集的数据包，包括：根据所述PDU集信息以及数据包的包头和/或流特征，确定所述第四网络设备接收的数据包是否属于所述PDU集的数据包。
在本公开实施例中，根据PDU集信息和数据包的包头□或流特征，确定每一个经过接入网节点的数据包是否属于一个PDU集内的数据包。
示例性地，数据包的包头包括一个或多个字段，这些字段指示数据包的类型和/或流特征。例如，该包头内包括指示数据包所使用传输协议的字段。根据该传输协议的字段能够，确定第四网络设备接收到的数据包是否属于PDU集的数据包。
再例如根据包头的类型，确定接入网节点接收的数据包是否属于PDU集。例如，不同类型的包头具有不同的数据格式，因此可以根据包头的数据格式确定第三网络设备接收到数据包是否属于PDU集。
所述流特征包括但不限于业务数据流的三元组和/或五元组。例如，所述三元组可包括：源网络协议(Internet Protocol，IP)地址、目标IP地址以及协议信息。所述无源组可包括：源网络协议(Internet  Protocol，IP)地址、目标IP地址、源端口号、目的端口号以及协议信息。
SMF支持对一个UE的每一个QoS流或SDF、每一个会话(Session)、每一个网络切片的PDU集丢弃的丢包用量信息的统计。例如，当基于PDU集的PDU处理时，基站丢弃的数据包的使用情况，尤其是下行数据包进行监控，得到丢包用量信息。
监控由分配给会话或流的PCC规则的PDU集丢弃阈值执行，或PDU会话，或单个网络切片中为某个UE建立的所有PDU会话。
对于SDF或者对于PDU会话，或者对于S-NSSAI传输的所有PDU会话。如果一个UE的PDU集丢弃的监控数据使用达到了PDU集丢弃值的一定百分比，通过运营商管理设备或应用服务提供商定义的阈值检测到，PCF可能会应用一个策略决定来加强PDU会话或PCC规则的流量限制。
此处的流量限制包括但不限于：PCF可不允许有意/合法丢弃数据包，或更新PCC规则以更改QoS或计费关键字。
当某个流/PDU会话的PDU集丢弃数据使用率低于PDU集丢弃值的百分比时，PCF可能会放松对流或PDU会话或业务数据流的流量限制。
SMF根据监控关键字，进行丢包用量监控，以请求PDU集丢包用量信息的报告。
SMF为激活的PCC规则中的每个监控关键字可生成使用报告规则。该监控关键可以是预先配置的在SMF上，也可以是从PCF接收的。
SMF还向UPF/RAN提供报告触发事件的事件信息。该事件信息可用于何时报告PDU集的丢包用量信息。UPF或者RAN在检测到触发事件或者监控的丢包用量达到丢包阈值上，会向SFM发送包含丢包用量信息的报告。
SMF根据PCF的授权、计费功能(Charging Trigger Function，CTF)或本地配置，决定PDU集的丢弃阈值。此处的丢弃阈值可为前述丢包阈值的一种。CTF可为SMF包含的功能之一。
UPF和/或接入网节点被强制监控PDU集丢弃数据，得到丢包用量信息或记录被丢弃的数据包。
如果是计费监控，则SMF(CTF)向PCF报告，计费用量信息和/或丢包用量信息。CTF可为计费触发功能(Charging Trigger Function，CTF)，此处的CTF可属于所述SMF的组成部分。
由于以下原因导致PDU集丢弃数据包：
PDU集延迟预算超过PSDB；
超过PDU集错误率；
从属PDU集交付失败；
重要PDU集交付失败。
此处的交付是指将数据包或者PDU集发送给终端(即用户设备(User Equipment，UE))。

PCF生成并提供PCC规则，包括PDU集相关的QoS和用量监控信息，给SMF。
PCF支持对一个UE的每一个SDF、每一个Session、每一个S-NSSAI的PDU集丢包用量信息(当基于PDU集的QoS处理时，RAN丢弃的数据包的使用情况，尤其是下行数据包)进行监控。
监控由分配给SDF的PCC规则、PDU会话或S-NSSAI中为某个UE建立的所有PDU会话的PDU集监控阈值来执行。
(对于SDF，或者对于PDU会话，或者对于S-NSSAI)，如果一个UE的PDU集丢弃的监控数据使用达到了PDU集丢弃值的一定百分比(通过操作员/应用服务提供商定义的阈值检测到)，PCF可能会应用一个策略决定来加强PDU会话或PCC规则的流量限制(例如，不允许有意/合格的丢弃，或更新PCC规则以更改QoS或充电关键字，并与SMF进行相应的交互。当某个UE的PDU集丢弃数据使用率低于PDU集丢弃值的百分比时，PCF可能会放松对PDU session或PCC规则的流 量限制。

SMF根据监控关键字和触发器向用量监控请求PDU集丢弃使用信息的报告。SMF为激活的PCC规则中的每个监控关键字生成使用报告规则，这些监控关键字可以是预先配置的，也可以是从PCF接收的。
SMF还向UPF/RAN提供报告触发事件，以确定何时报告PDU集丢弃使用信息。报告触发事件(例如，触发器、阈值信息等)支持规则级别报告或PDU会话级别报告。
SMF根据从PCF、CHF或本地配置收到的余量来决定PDU集的下降阈值。
UPF和/或NG-RAN中强制监控PDU集丢弃数据的使用情况。
如果是计费监控，则SMF(CTF)向CHF报告计费用量信息(在UPF和RAN偏移量处测量)。
