为了使得本公开的目的、技术方案和优点更为明显，下面将参照附图详细描述根据本公开的示例实施例。在附图中，相同的参考标号自始至终表示相同的元件。应当理解：这里描述的实施例仅仅是说明性的，而不应被解释为限制本公开的范围。
本公开实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term  Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统，5G系统或未来演进的移动通信系统等。
示例性的，本公开实施例应用的通信系统100如图1所示。该通信系统100可以包括网络设备110，网络设备110可以是与终端120(或称为通信终端、终端)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端进行通信。可选地，该网络设备110可以是GSM系统或CDMA系统中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，还可以是5G通信系统中的基站，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
该通信系统100还包括位于网络设备110覆盖范围内的至少一个终端120。作为在此使用的“终端”包括但不限于经由有线线路连接，如经由公共交换电话网络(Public Switched Telephone Networks，PSTN)、数字用户线路(Digital Subscriber Line，DSL)、数字电缆、直接电缆连接；和/或另一数据连接/网络；和/或经由无线接口，如，针对蜂窝网络、无线局域网(Wireless Local Area Network，WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器；和/或另一终端的被设置成接收/发送通信信号的装置；和/或物联网(Internet of Things，IoT)设备。被设置成通过无线接口通信的终端可以被称为“无线通信终端”、“无线终端”或“移动终端”。移动终端的示例包括但不限于卫星或蜂窝电话；可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(Personal Communications System，PCS)终端；可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位系统(Global Positioning System，GPS)接收器的PDA；以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。终端可以指接入终端、用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、5G网络中的终端或者未来演进的PLMN中的终端等。

图3示意性示出了根据本公开的一实施例的消息传输方法的流程图。图3实施例提供的方法可以由应用功能网元执行，但本公开并不限定于此。
如图3所示，本公开实施例提供的方法可以包括：
在S310中，发送业务流的第一服务质量请求消息，所述第一服务质量请求消息包括第一连接标识信息和第一服务质量参数。
其中，所述第一服务质量请求消息用于指示策略控制功能网元根据所述第一服务质量请求消息将第一策略控制计费规则发送至第一协议数据单元会话对应的第一会话管理功能网元，所述第一策略控制计费规则包括所述第一连接标识信息和所述第一服务质量参数。
示例性的，可以将业务流的第一服务质量(Quality of Service，QoS)请求消息传输至策略控制功能网元，所述第一服务质量请求消息包括应用功能标识、第一连接标识信息和第一服务质量参数。
本公开实施例中，QoS请求消息是指AF网元向网络发出的，以请求对传输该业务流的数据包执行相应的QoS规则或QoS执行规则的消息。第一QoS请求消息可以是任意的一个QoS请求消息。AF网元可以直接将该第一QoS请求消息发送给PCF网元，也可以通过NEF网元间接发送给PCF网元，本公开对此不做限定。
本公开实施例中的第一QoS请求消息中可以包括发送该第一QoS请求消息的AF的标识信息(即应用功能标识，可以表示为AF ID(identity))，还可以包括第一连接标识信息(connection ID)和第一QoS参数。
本公开实施例中的connection ID包括HTTP(HyperText Transfer Protocol，超文本传输协议)3/QUIC(Quick UDP Internet Connection，快速UDP互联网连接协议)协议中的连接标识信息，其中，UDP是User Datagram Protocol的简写，即用户数据报协议。在HTTP3/QUIC协议中，业务服务器和用户交互协议的包头信息，在数据包头中增加了连接标识信息，这样，当用户的IP地址发生变化时，业务服务器仍然可以根据该连接标识信息正确的关联用户的业务上下文信息。第一连接标识信息可以是任意的一个connection ID。
本公开实施例中，第一服务质量参数可以根据实际业务需求进行设定，本公开不对 其进行限定。
在示例性实施例中，所述第一服务质量请求消息可以包括流描述符。该流描述符中可以包括该第一连接标识信息。但本公开并不限定于此，在其它实施例中，第一连接标识信息可以位于流描述符外，即在该第一QoS请求消息中，第一连接标识信息可以是与流描述符并列的信息元素，或者，该第一连接标识信息位于该流描述符内，本公开对此不做限定。
在示例性实施例中，所述流描述符还包括以下中的至少一项：源网络(IP)地址；源端口号；目的网络(IP)地址；目的端口号；传输协议。
在示例性实施例中，当所述流描述符包括传输协议时，所述传输协议包括快速用户数据报协议互联网连接协议(即QUIC协议)。
在示例性实施例中，所述第一服务质量请求消息还可以包括终端的第一网络地址(例如UE IP地址，为了区分，这里称之为第一网络地址)，当第一QoS请求消息中包含UE IP地址时，可以直接根据该UE IP地址确定对哪个UE传输的业务流的数据包进行后续的第一数据包检测规则的检测，由此可以简化网络传输过程。可以理解的是，在其它实施例中，第一QoS请求消息中也可以不包括UE IP地址，此时，在后续执行过程中，可以根据该第一连接标识信息先确定所关联的UE IP地址，然后再确定对哪个UE传输的业务流的数据包进行后续的第一数据包检测规则的检测。
在示例性实施例中，所述第一服务质量请求消息还可以包括请求有效时间和/或生效位置信息。
本公开实施例中，请求有效时间是指该第一QoS请求消息的生效时间，超过该请求有效时间，该第一QoS请求消息请求针对该UE的具有该第一连接标识信息的特定业务流的第一QoS参数将失效。
本公开实施例中，生效位置信息是指该第一QoS请求消息针对UE位于什么地理范围或地理位置时才会生效，而对于该UE位于该生效位置信息之外时则不会生效，例如UE发生移动，超出了该生效位置信息之外，则此时AF请求的第一QoS参数不适用。
本公开实施例中，业务流是指针对某一或某些业务，终端发送的上行数据包和/或业务服务器发出的下行数据包在网络中传输所形成的业务流，业务可以根据实际需求设置。例如，业务可以是多媒体业务，但本公开并不限定于此。
可选的，在S320中，接收针对所述第一服务质量请求消息的第一响应消息，所述第一响应消息可以包括第一指示信息，所述第一指示信息可以用于指示是否同意所述第一服务质量请求消息。
本公开实施例中，AF网元可以从PCF网元和/或NEF网元接收该第一响应消息，该第一响应消息中的第一指示信息可以用于指示PCF网元和/或NEF网元是否同意该第一QoS请求消息。
所述第一服务质量请求消息可以用于指示所述策略控制功能网元，在所述第一指示信息指示同意所述第一服务质量请求消息时，根据所述第一服务质量请求消息确认第一协议数据单元(Protocol Data Unit，PDU)会话，更新或生成第一策略控制计费(Policy Control and Charging，PCC)规则，将所述第一策略控制计费规则发送至所述第一协议数据单元会话对应的第一会话管理功能网元，所述第一策略控制计费规则可以包括所述第一连接标识信息和所述第一服务质量参数。
在示例性实施例中，当所述第一指示信息指示同意所述第一服务质量请求消息时，所述第一响应消息还可以包括第一交互参考标识信息(transaction reference ID，也可以称之为交易标识)。第一交互参考标识信息用于确定第一服务质量请求消息中的第一连接标识信息。因为AF网元在实际情况中，可能会向网络发起多个请求，与该第一QoS请求消息关联的UE IP地址和connection ID，后续均有可能发生变化，因此，当PCF网元和/或NEF网元同意该第一QoS请求消息时，PCF网元和/或NEF网元可以通过该第一响应消息向AF网元返回第一交互参考标识信息，以使得AF网元后续在需要将第一连接标识信息更新为第二连接标识信息时，可以通过该第一交互参考标识信息唯一确定所要更新是哪个第一QoS请求消息中的第一连接标识信息。
在示例性实施例中，本公开实施例提供的方法还可以包括：发送更新所述业务流的第二服务质量请求消息，所述第二服务质量请求消息包括第二连接标识信息和所述第一交互参考标识信息；所述第二服务质量请求消息用于指示所述策略控制功能网元根据所述第二服务质量请求消息将第二策略控制计费规则发送至所述第一会话管理功能网元，所述第二策略控制计费规则包括所述第二连接标识信息，所述第二策略控制计费规则是根据所述第二连接标识信息和所述第一交互参考标识信息对所述第一策略控制计费规则更新得到的。
示例性的，将更新所述业务流的第二服务质量请求消息传输至所述策略控制功能网元，所述第二服务质量请求消息可以包括所述应用功能标识以及第二连接标识信息。可选的，可以接收针对所述第二服务质量请求消息的第二响应消息，所述第二响应消息可以包括第二指示信息，所述第二指示信息可以用于指示是否同意所述第二服务质量请求消息。
所述第二服务质量请求消息可以用于指示所述策略控制功能网元，在所述第二指示信息指示同意所述第二服务质量请求消息时，根据所述第二服务质量请求消息更新所述第一策略控制计费规则获得第二策略控制计费规则，将所述第二策略控制计费规则发送至所述第一会话管理功能网元，所述第二策略控制计费规则可以包括所述第二连接标识信息。
在示例性实施例中，所述第二服务质量请求消息还可以包括第一交互参考标识信息。
本公开实施方式提供的消息传输方法，当应用功能网元向策略控制功能网元发起业务流的第一服务质量请求消息时，通过在该第一服务质量请求消息中携带第一连接标识信息和第一服务质量参数，从而使得接收到该第一服务质量请求消息的策略控制功能网元，能够在该第一服务质量请求消息的指示下，确认第一协议数据单元会话，并更新或生成第一策略控制计费规则，将更新或生成的第一策略控制计费规则发送至该第一协议数据单元会话对应的第一会话管理功能网元，该第一策略控制计费规则携带上述第一连接标识信息及其对应的第一服务质量参数，以用于优化网络传输，减少AF和网络的交互次数。
图4实施例示出了AF网元主动请求针对UE的特定业务流的QoS保障的示意图。如图4所示，本公开实施例提供的方法可以包括：
在S41中，AF网元向NEF(Network Exposure Function，网络开放功能)网元发送第一QoS请求消息，该第一QoS请求消息可以包含AF ID、第一连接标识信息和第一QoS参数。
本公开实施例中，AF网元发送业务流的第一QoS请求消息给NEF网元，第一QoS请求消息可以包含AF标识，UE IP地址(终端的第一网络地址)，流描述符(可以包含第一连接标识信息，可选的，还可以包含目的IP地址或目的端口号，或者传输协议等中的至少一项)，第一QoS参数等。
可选的，第一QoS请求消息还可以包含该第一QoS请求消息的请求有效时间和/或生效位置信息。其中生效位置信息可以用实际的地理位置信息，街道名称信息，基站信息，小区信息等表示。本公开实施例中的请求有效时间和/或生效位置信息是与第一connection ID相关联的。
本公开实施例通过在第一QoS请求消息中增加第一连接标识信息，这样，即使后续当UE IP地址发生变化(例如从第一UE IP地址变更为第二UE IP地址，如从WiFi变更为5G网络，或者从5G网络变更为4G网络等)，但是由于第一连接标识信息没有变化，网络依然依据相同的第一QoS参数执行相同的QoS策略信息，而不需要AF重新请求QoS信息，由此降低了AF与网络之间的交互。
例如，假设UE IP地址从IP1变更为IP2，则传输该业务流的UPF网元对该UE发送/接收的数据包进行检测时，虽然此时该数据包的源IP地址/目的IP地址为从IP1变更为了IP2，但由于UPF检测到的数据包的连接标识信息仍然是第一连接标识信息，因此，UPF均执行相同的第一QoS执行规则。
可选的，AF网元发送给NEF网元的第一QoS请求消息还可以包含业务流模板信息、该业务流的DNN(data network name，数据网络名称)信息和/或S-NSSAI(Single Network Slice Selection Assistance Information，单网络切片辅助信息)信息等中的至少一种，该信息用来表示该AF的请求是针对哪些业务流。
可选的，AF网元发送给NEF网元的第一QoS请求消息也可以不包含该业务流的DNN信息和/或S-NSSAI信息等。AF网元可以预先通过其它消息将AF ID、该业务流的DNN信息和/或S-NSSAI信息等发送给NEF网元，NEF网元可以将AF ID与业务流模板信息、该业务流的DNN信息和/或S-NSSAI信息等关联存储起来，当NEF网元接收到该第一QoS请求消息时，可以根据该第一QoS请求消息中携带的AF ID进行查找，获得该业务流的DNN信息和/或S-NSSAI信息等，以此可以降低第一QoS请求消息携带的数据量。
在示例性实施例中，业务流模板信息可以包括业务流的源IP地址(源网络地址)、源端口号、目的IP地址(目的网络地址)、目的端口号、FQDN(Fully Qualified Domain Name，全限定域名)、APP ID(Application identity，应用标识)等中的一种或多种。

在一些实施例中，PCF网元接收到NEF网元发送的第一QoS请求消息之后，可以对第一QoS请求消息进行鉴权和认证，生成第一响应消息，并通过NEF网元返回AF网元。即PCF网元和NEF网元可以对第一QoS请求消息进行双重鉴权和认证。
在另一些实施例中，当NEF网元接收到该第一QoS请求消息之后，也可以不对该第一QoS请求消息进行鉴权和认证，而是直接转发给PCF网元，由PCF网元对该第一QoS请求消息进行鉴权和认证。
NEF网元进一步返回第一响应消息给AF网元，如果第一指示信息指示同意该第一QoS请求消息，NEF网元还可以返回第一交互参考标识信息(transaction reference ID)给AF。

可以理解的是，第一数据包检测规则及其对应的第一QoS执行规则可以合并为同一规则，也可以分为不同的规则，也可以作为其他规则的一部分，也可以作为服务质量配置文件(QoS(Quality of Service，服务质量)profile)的一部分，根据执行实体的不同，该规则可能会具有不同的名称，本公开对此不做限定。
