Description

一种业务流的处理方法及设备 技术领域
本申请涉及通信技术领域，尤其涉及一种业务流的处理方法及设备。
背景技术
随着通信技术的发展，第五代移动(5th generation，5G)通信技术问世，5G通信技术是新一代蜂窝移动通信技术，也是第四代(forth Generation，4G)通信技术之后的延伸。
第三代合作伙伴计划(third generation partnership project，3GPP)标准，定义了5G通信网络的架构，在该架构中，用户设备(user equipment，UE)可以通过3GPP接入网接入到5G核心网，也可以通过非3GPP接入网接入到5G核心网，也可以同时通过3GPP接入网和非3GPP接入网接入到5G核心网。
另外，3GPP标准还定义了，UE与5G核心网之间交互的业务数据流分为保障流比特速率(guaranteed bit rate，GBR)服务质量流(quality of service flow，QoS flow)和非保障流比特速率(non-guaranteed bit rate，non-GBR flow)QoS flow两种。
现有技术中，GBR QoS flow只能在3GPP接入网侧或者非3GPP接入网侧中的一侧建立，当业务流数据需要从一侧移动到另一侧时，需要在另一侧重新建立GBR QoS flow，导致了时延的增加。
发明内容
本申请实施例提供了一种业务流的处理方法及设备，用于降低业务流数据从一侧移动到另一侧时的时延。
本申请实施例的第一方面提供一种业务流的处理方法：
在会话建立和会话修改过程中，第一核心网网元会接收到来自第二核心网网元的策略规则，由于该策略规则用于指示第一核心网网元分别在两个网络中为保障流比特速率服务质量流GBR QoS flow分配资源。
因此，第一核心网网元会根据策略规则为保障流比特速率服务质量流GBR QoS flow在第一网络和第二网络分配资源，其中第一网络和第二网络的网络类型可以相同，也可以不同。
由于第一核心网网元在第一网络和第二网络分别为GBR QoS flow分配了资源，所以GBR QoS flow对应的业务流数据既可以从第一网络进行传输，也可以从第二网络进行传输；当由于某种原因，需要对业务流数据进行移动时，不需要重新为GBR QoS flow分配资源，可以直接将业务流数据从第一网络移动到第二网络，也可以直接将业务流数据从第二网络移动到第一网络，所以时延较小。
基于第一方面，本申请实施例还提供了第一方面的第一种实施方式：
第一核心网网元根据策略规则为GBR QoS flow在第一网络和第二网络分配资源包括：
第一核心网网元根据策略规则为GBR QoS flow配置第一资源和第二资源，其中第一资 源对应第一网络，第二资源对应第二网络。
第一核心网网元为第一网络配置了第一资源，并为第二网络配置了第二资源，因此可以根据第一资源在第一网络中传输业务流数据，也可以根据第二资源在第二网络中传输业务流数据。
基于第一方面的第一种实施方式，本申请实施例还提供了第一方面的第二种实施方式：
策略规则包含服务质量QoS规则和分流规则，其中Qos规则中可以包含Qos参数，分流规则中可以包含分流模式信息。
这样，第一核心网网元则可以根据QoS规则和分流规则配置第一资源和第二资源。
基于第一方面的第二种实施方式，本申请实施例还提供了第一方面的第三种实施方式：
当QoS规则包括保证流带宽的第一参数和最大流带宽的第二参数时，其中第二参数大于第一参数，第一核心网网元根据策略规则为GBR QoS flow配置第一资源和第二资源包括：
第一核心网网元将第一资源中的保证流带宽配置为第一参数，第一核心网网元将第二资源中的保证流带宽配置为0，并将第二资源中的最大流带宽配置为第二参数。
本申请实施例提供了配置第一资源和配置第二资源的一种可行方案，在该方案中，分别对第一资源中的保证流带宽和第二资源中的最大流带宽进行了配置，使得业务流数据在第一网络中的带宽能够得到保证。
基于第一方面的第二种实施方式，本申请实施例还提供了第一方面的第四种实施方式：
当QoS规则包括保证流带宽的第一参数和最大流带宽的第三参数时，其中第三参数大于第一参数，第一核心网网元根据策略规则为GBR QoS flow配置第一资源和第二资源包括：
第一核心网网元将第一资源中的保证流带宽配置为第一参数，第一核心网网元将第二资源中的保证流带宽配置为第三参数与第一参数的差值。
本申请实施例提供了配置第一资源和配置第二资源的一种可行方案，在该方案中，分别对第一资源中的保证流带宽和第二资源中的保证流带宽进行了配置，使得业务流数据在第一网络和第二网络中的带宽均能够得到保证。
基于第一方面的第二种实施方式，本申请实施例还提供了第一方面的第五种实施方式：
当QoS规则包括保证流带宽的第一参数和第四参数时，其中第四参数为最大数据突发流量，最大数据突发流量大于第一参数时，第一核心网网元根据策略规则为GBR QoS flow配置第一资源和第二资源包括：
第一核心网网元将第一资源中的保证流带宽配置为第一参数，第一核心网网元将第二资源中的保证流带宽配置为(MDBV/PDB-GFBR/AW)*AW，其中MDBV表示最大数据突发流量，PDB表示GBR QoS flow的包延迟预算，GFBR表示第一参数，AW表示GBR QoS flow的平均窗口。
本申请实施例提供了配置第一资源和配置第二资源的一种可行方案，在该方案中，分别对第一资源中的保证流带宽和第二资源中的保证流带宽进行了配置，使得业务流数据在第一网络和第二网络中的带宽均能够得到保证，其中第二资源中的保证流带宽是根据MDBV配置的，适用于时延重要的业务流数据。
基于第一方面的第二种实施方式，本申请实施例还提供了第一方面的第六种实施方式：
当QoS规则包括保证流带宽的第一参数时，第一核心网网元根据策略规则为GBR QoS flow配置第一资源和第二资源包括：
第一核心网网元将第一资源中的保证流带宽配置为第一参数，第一核心网网元根据预置的第一本地策略将第二资源中的保证流带宽配置为第五参数。
本申请实施例提供了配置第一资源和配置第二资源的一种可行方案，在该方案中，分别对第一资源中的保证流带宽和第二资源中的保证流带宽进行了配置，使得业务流数据在第一网络和第二网络中的带宽均能够得到保证，其中第二资源中的保证流带宽是根据第一本地策略配置的，因此第二资源中保证流带宽的配置方法比较灵活。
基于第一方面的第二种实施方式，本申请实施例还提供了第一方面的第七种实施方式：
当QoS规则包括第一网络对应的保证流带宽的第一参数和第二网络对应的保证流带宽的第六参数时，第一核心网网元根据策略规则为GBR QoS flow配置第一资源和第二资源包括：
第一核心网网元将第一资源中的保证流带宽配置为第一参数，第一核心网网元将第二资源中的保证流带宽配置为第六参数。
本申请实施例提供了配置第一资源和配置第二资源的一种可行方案，在该方案中，QoS规则直接指定了第一网络和第二网络各自对应的保证流带宽的参数，这样，第一核心网网元可以直接根据指定的参数对第一资源中的保证流带宽和第二资源中的保证流带宽进行配置，使得业务流数据在第一网络和第二网络中的带宽均能够得到保证。
基于第一方面的第三种实施方式，或第一方面的第四种实施方式，或第一方面的第五种实施方式，或第一方面的第六种实施方式，或第一方面的第七种实施方式，本申请实施例还提供了第一方面的第八种实施方式：
分流规则包括分流模式信息；分流模式信息可以包括：分流模式为优先级模式，第一网络的优先级高于第二网络的优先级。
或者，分流模式信息也可以包括：分流模式主从模式，第一网络为主网络，第二网络为从网络。
或者，分流模式信息也可以包括：分流模式为最小时延模式，第一网络的时延比第二网络的时延小。
在本申请实施例中，根据分流规则对第一网络和第二网络进行区分，使得第一核心网网元可以根据区别结果分别对第一资源和第二资源进行不同的配置，从而实现对第一资源和第二资源更合理的配置。
基于第一方面的第二种实施方式，本申请实施例还提供了第一方面的第九种实施方式：
当QoS规则包括保证流带宽的第一参数，分流规则包括分流模式信息，分流模式信息包括：分流模式为均衡模式，第一网络对应的保证流带宽与第二网络对应的保证流带宽的比例时，第一核心网网元根据策略规则为GBR QoS flow配置第一资源和第二资源包括：
第一核心网网元根据第一参数和比例配置第一资源中的保证流带宽和第二资源中的保证流带宽。
由于分流模式为均衡模式，所以业务流数据会同时在第一网络和第二网络中进行传输， 因此可以直接在QoS规则设定第一网络和第二网络的保证流带宽的比例，这样，第一核心网网元根据比例对第一参数进行分配，便可以确定第一资源中的保证流带宽和第二资源中的保证流带宽，使得业务流数据在第一网络和第二网络中的带宽均能够得到保证。
基于第一方面的第二种实施方式，本申请实施例还提供了第一方面的第十种实施方式：

PCF网元，包含策略控制决策和基于流计费控制的功能，包含用户签约数据管理功能，策略控制功能，计费策略控制功能，QoS控制等。
终端设备(terminal device)，也可以称为用户设备(user equipment，UE)，是一种具有无线收发功能的设备，可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述终端设备可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。为便于说明，图1用UE代替终端设备。
图1中的N1、N2、N3、N4、N6、N11、Y1、Y2和NWu分别表示接口序列号。这些接口序列号的含义可参见第三代合作伙伴计划(third generation partnership project，3GPP)标准协议中定义的含义，在此不做限制。
从图1中可以看出，终端设备可以通过3GPP接入网接入5G核心网，具体地，终端设备可以与3GPP接入网连接，终端设备也可以通过N1接口直接与AMF网元连接，3GPP接入网可以通过N2接口与AMF网元连接，3GPP接入网可以通过N3接口与UPF网元连接。
终端设备也可以通过非可信非3GPP接入网接入5G核心网，具体地，终端设备可以通过Y1接口与非可信非3GPP接入网连接，终端设备也可以通过N1接口直接与AMF网元连接，并且在该方式下，引入了N3IWF网元，与非可信非3GPP接入网可以通过Y2接口与N3IWF网元连接，N3IWF网元可以通过N2接口与AMF网元连接，N3IWF网元可以通过N3接口与UPF网元连接，因此N3IWF网元对于5G核心网来说相当于无线接入网(Radio Access Network，RAN)节点。
请参阅图2，本申请实施例中终端设备接入到5G核心网的另一个架构示意图。如图2所示，在该架构中，也主要包含终端设备、接入网和5G核心网三大部分。其中接入网包括 3GPP接入网和可信非3GPP接入网Trusted Non-3GPP Access Network，可信非3GPP接入网Trusted Non-3GPP Access Network包含可信非3GPP网关功能(Trusted Non-3GPP Gateway Function，TNGF)网元和可信非3GPP接入点Trusted Non-3GPP Access Point，5G核心网包括接入和AMF网元、PCF网元、SMF网元和UPF网元。
由于前面已经对AMF网元、SMF网元、UPF网元、PCF网元和终端设备进行了介绍，故在此不做赘述，其中为了便于说明，图2用UE代替终端设备。
图2中的N1、N2、N3、N4、N6、N11、Yt、Ta、Tn和NWt分别表示接口序列号。这些接口序列号的含义可参见第三代合作伙伴计划(third generation partnership project，3GPP)标准协议中定义的含义，在此不做限制。
从图2中可以看出，终端设备可以通过3GPP接入网接入5G核心网，具体地，终端设备可以与3GPP接入网连接，终端设备也可以通过N1接口直接与AMF网元连接，3GPP接入网可以通过N2接口与AMF网元连接，3GPP接入网可以通过N3接口与UPF网元连接。
终端设备也可以通过可信非3GPP接入网接入5G核心网，具体地，终端设备可以通过Yt接口与可信非3GPP接入网中的可信非3GPP接入点连接，终端设备也可以通过N1接口直接与AMF网元连接，并且在该方式下，在可信非3GPP接入网中引入了TNGF网元，可信非3GPP接入点可以通过Ta接口与N3IWF网元连接，N3IWF网元可以通过N2接口与AMF网元连接，N3IWF网元可以通过N3接口与UPF网元连接，因此N3IWF网元对于5G核心网来说也相当于RAN节点。
基于上述分析可以看出，终端设备可以通过两个接入网分别接入5G核心网，其中这两个接入网包括但不限于图1所示的两个接入网和图2所示的两个接入网。当终端设备通过两个接入网分别接入5G核心网时，终端设备与5G核心网之间的业务流数据可以从两个接入网中的一个接入网进行传输，也可以从两个接入网中的另一个接入网进行传输。但由于只在一个接入网中建立GBR QoS flow，即预先只在一个接入网中分配资源，所以当GBR QoS flow对应的业务流数据需要从一个接入网移动到另一个接入网时，需要在另一个接入网重新建立GBR QoS flow，存在时延的问题。其中，在本申请实施例中，业务流数据从一个接入网移动到另一个接入网，包括将业务流数据从一个接入网切换到另一个接入网的情况。
为了解决这个问题，本申请实施例提供了业务流的处理方法，分别在两个接入网预先分配资源，以降低业务流数据从一侧移动到另一侧时的时延。
下面将对业务流的处理方法进行具体介绍，在对业务流的处理方法进行介绍的过程中，涉及到第一核心网网元、第二核心网网元和第三核心网网元，需要说明的是，第一核心网网元可以为5G核心网中的SMF网元，第二核心网网元可以为5G核心网中的PCF网元，第三核心网网元可以为5G核心网中的UPF网元。第一核心网网元、第二核心网网元和第三核心网网元也可以是未来通信如第六代(6th generation，6G)网络中具有上述AMF、SMF、PCF、AF、RAN、NEF、UPF的功能的网元，本申请实施例对此不限定。另外，为了能够在两个接入网为GBR QoS flow配置资源，需要保证终端设备预先通过这两个接入网注册到5G核心网。
具体地，请参阅图3，本申请实施例中业务流的处理方法的第一实施例示意图。如图3 所示，本申请实施例提供了一种业务流的处理方法的第一实施例，包括：
101，第二核心网网元确定需要为保障流比特速率服务质量流GBR QoS flow在第一网络和第二网络分配资源。
第一网络可以理解为包含终端设备、接入网设备以及5G核心网的网络，在该第一网络中，终端设备和5G核心网之间可以通过接入网设备形成第一传输路径；第二网络也可以理解为包含终端设备、接入网设备以及5G核心网的网络，在该第二网络中，终端设备和5G核心网之间可以通过接入网设备形成第二传输路径。
其中，第一网络可以为采用3GPP接入技术建立的网络或者采用非3GPP接入技术建立的网络；第二网络可以为采用3GPP接入技术建立的网络或者采用非3GPP接入技术建立的网络。当第一网络为采用3GPP接入技术建立的网络时，第一网络中的接入网设备则为3GPP接入网设备，当第一网络为采用非3GPP接入技术建立的网络时，第一网络中的接入网设备则为非3GPP接入网设备或非3GPP接入网网关；同理，当第二网络为采用3GPP接入技术建立的网络时，第二网络中的接入网设备则为3GPP接入网设备，当第二网络为采用非3GPP接入技术建立的网络时，第二网络中的接入网设备则为非3GPP接入网设备或非3GPP接入网网关。
确定需要为GBR QoS flow在第一网络和第二网络分配资源有多种方式，其中一种方式是根据终端设备的业务信息和本地运营商策略确定，其中业务信息包括但不限于终端设备的应用标识、应用类型、IP五元组、源MAC地址和目的MAC地址。例如，每个应用类型都对应一个本地运营商策略，当应用类型为delay critical类型时，对应的本地运营商策略指示需要为GBR QoS flow在第一网络和第二网络分配资源，以保证应用类型对应的业务流数据传递的时延需求，那么第二核心网网元便可以根据应用类型确定需要为GBR QoS flow在第一网络和第二网络分配资源。再例如，若特定的IP五元组对应的本地运营商策略指示需要为GBR QoS flow在第一网络和第二网络分配资源，那么第二核心网网元可以根据IP五元组确定需要为GBR QoS flow在第一网络和第二网络分配资源。
需要说明的是，操作101的执行存在多种场景，下面对该多种场景一一进行介绍。
第一，操作101的执行可以发生在多接入协议数据单元(Multi-Access Protocol Data Unit，MA PDU)会话建立过程中。例如，当需要建立MA PDU会话时，终端设备可以首先向AMF网元发送非接入层(Non-access stratum，NAS)消息，该NAS消息中包含MA PDU会话建立请求。然后AMF网元会将该MA PDU会话建立请求转发至SMF网元，SMF网元会发送会话管理策略关联建立请求消息至PCF网元，会话管理策略关联建立请求消息用于请求会话建立的策略规则，PCF网元在接收到会话管理策略关联建立请求消息后，则会先执行操作101。
第二，操作101的执行也可以发生在MA PDU会话修改过程中。例如，在当前MA PDU会话中，AMF网元直接向PCF网元发送重新建立GBR QoS flow的请求，PCF网元在接收到该重新建立GBR QoS flow的请求后，也会执行操作101。
第三，操作101的执行还可以发生在本地运营商策略修改的场景中。例如，假设当前的本地运营商策略指示仅在第一网络中建立GBR QoS flow，当本地运营商策略发生修改时， 本地运营商策略指示需要为GBR QoS flow在第一网络和第二网络分配资源，则PCF网元也可以执行操作101。
在上述多种场景下，PCF网元为GBR QoS flow在第一网络和第二网络分配资源，终端设备与5G核心网之间对应地存在MA PDU会话，因此终端设备需要具备多接入的能力，具体可以通过标识指示终端设备具备多接入的能力，例如，该标识可以存在会话管理策略关联建立请求消息中，使得PCF网元根据该标识可以确定终端设备具备多接入的能力。
102，第二核心网网元向第一核心网网元发送策略规则。
第二核心网网元在确定需要为GBR QoS flow在第一网络和第二网络分配资源后，则会根据本地运营商策略等配置具体的策略规则，其中本申请实施例对配置策略规则的方法不做具体限定，该策略规则用于指示第一核心网网元为GBR QoS flow在第一网络和第二网络分配资源，然后会将策略规则发送至第一核心网网元，该策略规则可以携带在第二核心网网元发送给第一核心网网元的会话管理策略关联建立响应消息中，相应地，第一核心网网元则会来自第二核心网网元的策略规则。
103，第一核心网网元根据策略规则为保障流比特速率服务质量流GBR QoS flow在第一网络和第二网络分配资源。
第一核心网网元在接收到策略规则后，则会根据策略规则为GBR QoS flow在第一网络和第二网络分配资源，其中分配资源的方法有多种，可以由策略规则决定，本申请实施例对此不做具体限定。
在本申请实施例中，由于第一核心网网元在第一网络和第二网络分别为GBR QoS flow分配了资源，所以GBR QoS flow对应的业务流数据既可以从第一网络进行传输，也可以从第二网络进行传输；当由于某种原因，需要对业务流数据进行移动时，不需要重新为GBR QoS flow分配资源，可以直接将业务流数据从第一网络移动到第二网络，也可以直接将业务流数据从第二网络移动到第一网络，所以时延较小。
在上述第一实施例中，第一核心网网元为GBR QoS flow在第一网络和第二网络分配资源，下面将对第一核心网网元分配资源的过程进行具体说明。
请参阅图4，本申请实施例中分配资源的一个实施例示意图。如图4所示，在本申请实施例提供的业务流的处理方法的第二实施例中，第一核心网网元为GBR QoS flow在第一网络和第二网络分配资源包括：
201，第一核心网网元根据策略规则为GBR QoS flow配置第一资源和第二资源。
其中策略规则可以包含服务质量QoS规则和分流规则，QoS规则中可以包含QoS flow的相关参数，例如保证流带宽、最大流带宽和最大数据突发流量等，分流规则则可以包含分流模式信息，例如分流模式信息可以包含具体的分流模式，分流模式可以为优先级模式、主从模式、最小时延模式和均衡模式，除此之外，还可以是其他模式，本申请实施例对此不做限定。
第一资源对应第一网络，第二资源对应第二网络，本申请实施例对第一资源和第二资源的内容不做具体限定，具体可以根据策略规则进行确定。
202，第一核心网网元向第一网络中的接入网设备发送第一资源和分流规则。
203，第一核心网网元向第二网络中的接入网设备发送第二资源和分流规则。
可以理解的是，第一核心网网元可以通过AMF网元向第一网络中的接入网设备和第二网络中的接入网设备发送相关资源和分流规则；具体地，第一核心网网元可以向AMF网元发送包含第一资源、第二资源和分流规则的N1N2接口消息传递N1N2MessageTransfer消息，然后AMF网元向第一网络中的接入网设备发送包含第一资源和分流规则的N2接口PDU会话请求N2PDU Session Request消息，AMF网元向第二网络中的接入网设备发送包含第二资源和分流规则的N2PDU Session Request消息。
通过上述过程可以实现第一核心网网元将第一资源和分流规则发送至第一网络中的接入网设备，将第二资源和分流规则发送至第二网络中的接入网设备。
204，第一核心网网元向终端设备发送GBR QoS flow对应的第一资源、第二资源和分流规则。
可以理解的是，AMF网元在接收到来自第一核心网网元的第一资源、第二资源和分流规则后，可以直接向终端设备发送分流规则，而第一资源和第二资源可以分别通过第一网络中的接入网设备和第二网络中的接入网设备发送至终端设备；具体地，第一网络中的接入网设备在接收到第一资源后，会根据第一资源与终端设备建立空口资源，在建立空口资源的过程中，终端设备会接收到第一资源，同样地，第二机入网在接收到第二资源后，会根据第二资源与终端设备建立空口资源，在建立空口资源的过程中，终端设备会接收到第二资源。通过上述过程，可以实现第一核心网网元将第一资源、第二资源和分流规则发送至终端设备。
相应地，终端设备会接收来自第一核心网网元的与保障流比特速率服务质量流GBR QoS flow对应的第一资源、第二资源和分流规则，第一资源对应第一网络，第二资源对应第二网络。
205，第一核心网网元向第三核心网网元发送GBR QoS flow对应的第一资源、第二资源和分流规则。
可以理解的是，第一核心网网元可以与第三核心网网元建立N4会话，通过N4会话将第一资源、第二资源和分流规则发送至第三核心网网元。
相应地，第三核心网网元会接收来自第一核心网网元的与保障流比特速率服务质量流GBR QoS flow对应的第一资源、第二资源和分流规则，第一资源对应第一网络，第二资源对应第二网络。
206，第三核心网网元根据分流规则和第一资源通过第一网络中的接入网设备向终端设备发送GBR QoS flow对应的业务流数据。
需要说明的是，第三核心网网元根据分流规则可以确定传输业务流数据的具体方案。由于第一网络和第二网络均可以为采用3GPP接入技术建立的网络或者采用非3GPP接入技术建立的网络，所以本申请实施例可以假设第三核心网网元选择第一网络中的接入网设备进行业务流数据的传输。
207，当第三核心网网元确定第一网络中的接入网设备不能传输GBR QoS flow对应的业务流数据时，第三核心网网元根据第二资源通过第二网络中的接入网设备向终端设备发 送GBR QoS flow对应的业务流数据。
在本申请实施例中，第三核心网网元可以根据多种情况确定第一网络中的接入网设备不能传输GBR QoS flow对应的业务流数据，例如若第一网络中的接入网设备故障，则可以确定第一网络中的接入网设备不能传输GBR QoS flow对应的业务流数据；再例如，若第一网络中的接入网设备发生堵塞，在这种情况下，存在两种可能，第一种可能是GBR QoS flow对应的一部分业务流数据仍可以通过第一网络中的接入网设备进行传输，但由于堵塞，GBR QoS flow对应的另一部分业务流数据不能通过第一网络中的接入网设备进行传输，第二种可能是GBR QoS flow对应的业务流数据全部不能通过第一网络中的接入网设备进行传输，在本申请实施例中，将这两种可能均作为第一网络中的接入网设备不能传输GBR QoS flow对应的业务流数据的情况。
基于上述说明可知，当确定第一网络中的接入网设备不能传输GBR QoS flow对应的业务流数据时，第三核心网网元根据第二资源通过第二网络中的接入网设备向终端设备发送GBR QoS flow对应的业务流数据，同时，可以选择不通过第一网络中的接入网设备向终端设备发送GBR QoS flow对应的业务流数据，也可以选择通过第一网络中的接入网设备向终端设备发送GBR QoS flow对应的业务流数据，具体可以根据不能传输的实际情况以及分流规则来确定。
208，终端设备根据分流规则和第一资源通过第一网络中的接入网设备向第三核心网网元发送GBR QoS flow对应的业务流数据。
同样地，终端设备根据分流规则可以确定传输业务流数据的具体方案。由于第一网络和第二网络均可以为采用3GPP接入技术建立的网络或者采用非3GPP接入技术建立的网络，所以本申请实施例可以假设终端设备选择第一网络中的接入网设备进行业务流数据的传输。
209，当终端设备确定第一网络中的接入网设备不能传输GBR QoS flow对应的业务流数据时，终端设备根据第二资源通过第二网络中的接入网设备向第三核心网网元发送GBR QoS flow对应的业务流数据。
同样地，终端设备也可以根据多种情况确定第一网络中的接入网设备不能传输GBR QoS flow对应的业务流数据，该多种情况与操作206中提及的多种情况类似，具体可参照操作206中的多种情况进行理解。
当确定第一网络中的接入网设备不能传输GBR QoS flow对应的业务流数据时，终端设备也会选择第二网络中的接入网设备，或者选择第一网络中的接入网设备以及第二网络中的接入网设备传输GBR QoS flow对应的业务流数据，具体可参照操作206的说明进行理解。
在本申请实施例中，第三核心网网元和终端设备之间可以先通过第一网络中的接入网设备传输业务流数据，当第一网络中的接入网设备不能传输GBR QoS flow对应的业务流数据时，可以直接采用第二网络中的接入网设备传输GBR QoS flow对应的业务流数据，不需重新为GBR QoS flow在第二网络中配置资源，所以时延小。
基于前述说明可知，第一核心网网元可以根据策略规则为GBR QoS flow配置第一资源和第二资源，其中策略规则可以包括QoS规则和分流规则，但QoS规则和分流规则的内容 有多种可能，所以配置第一资源和第二资源也相应地存在多种方案。下面将以不同的QoS规则和分流规则，对配置第一资源和第二资源的过程进行具体说明。
本申请实施例提供的业务流的处理方法的第三实施例中，QoS规则包括保证流带宽的第一参数和最大流带宽的第二参数，其中第二参数大于第一参数，除此之外，第二参数也可以等于第一参数。
第一核心网网元根据策略规则为GBR QoS flow配置第一资源和第二资源包括：
第一核心网网元将第一资源中的保证流带宽配置为第一参数；
第一核心网网元将第二资源中的保证流带宽配置为0，并将第二资源中的最大流带宽配置为第二参数。
在本申请实施例中，根据第一参数对第一资源中的保证流带宽进行了配置，使得业务流数据在第一网络中的传输能够得到保证，而将第二资源中的保证流带宽配置为0，将第二资源中的最大流带宽配置为第二参数，能够节约第二网络中的资源。
本申请实施例提供的业务流的处理方法的第四实施例中，QoS规则包括保证流带宽的第一参数和最大流带宽的第三参数，其中第三参数大于第一参数。
第一核心网网元根据策略规则为GBR QoS flow配置第一资源和第二资源包括：
第一核心网网元将第一资源中的保证流带宽配置为第一参数；
第一核心网网元将第二资源中的保证流带宽配置为第三参数与第一参数的差值。
在本申请实施例中，将第二资源中的保证流带宽配置为第三参数和第一参数的差值，为了节约第二网络中的资源，该差值往往小于第一参数，并且可以将该差值设置地更小。
本申请实施例提供的业务流的处理方法的第五实施例中，QoS规则包括保证流带宽的第一参数和第四参数，第四参数为最大数据突发流量，且最大数据突发流量大于第一参数。
第一核心网网元根据策略规则为GBR QoS flow配置第一资源和第二资源包括：
第一核心网网元将第一资源中的保证流带宽配置为第一参数；
第一核心网网元将第二资源中的保证流带宽配置为(MDBV/PDB-GFBR/AW)*AW，其中MDBV表示最大数据突发流量，PDB表示GBR QoS flow的包延迟预算，GFBR表示第一参数，AW表示GBR QoS flow的平均窗口，GFBR/AW表示GBR QoS flow对应的业务数据流所需要保证的单位流量。
在本申请实施例中，第一核心网网元根据最大数据突发流量和保证流带宽的第一参数对第二资源中的保证流带宽进行了配置，尤其适用于时延重要的业务流数据；同样地，为了节约第二网络中的资源，往往将第二资源中的保证流带宽配置地较小。
在本申请实施例提供的业务流的处理方法的第六实施例中，QoS规则包括保证流带宽的第一参数；
第一核心网网元根据策略规则为GBR QoS flow配置第一资源和第二资源包括：
第一核心网网元将第一资源中的保证流带宽配置为第一参数；
第一核心网网元根据预置的第一本地策略将第二资源中的保证流带宽配置为第五参数。
在本申请实施例中，第一资源中的保证流带宽是第一核心网网元根据第一参数进行配 置的，而第二资源中的保证流带宽是第一核心网网元根据第一本地策略配置的，使得第二资源中的保证流带宽的配置更加灵活；同样地，为了节约第二网络中的资源，往往将第五参数配置地较小。
本申请实施例提供的业务流的处理方法的第七实施例中，QoS规则包括第一网络对应的保证流带宽的第一参数和第二网络对应的保证流带宽的第六参数。
第一核心网网元根据策略规则为GBR QoS flow配置第一资源和第二资源包括：
第一核心网网元将第一资源中的保证流带宽配置为第一参数；
第一核心网网元将第二资源中的保证流带宽配置为第六参数。
在本申请实施例中，QoS规则指定了第一网络和第二网络各自对应的保证流带宽，第一核心网网元根据QoS规则的指示即可完成第一资源和第二资源的配置。
在前述几个实施例中，第一核心网网元根据QoS规则分别对第一网络对应的第一资源和第二网络对应的第二资源进行了不同的配置，而在配置前可以先对第一网络和第二网路进行区分，然后根据区分结果对第一资源和第二资源进行前述的配置。而区分第一网络和第二网络可以根据分流规则进行，下面将对不同的分流规则进行具体介绍。
本申请实施例提供的业务流的处理方法的第八实施例中，分流规则包括分流模式信息。
分流模式信息包括：分流模式为优先级模式，第一网络的优先级高于第二网络的优先级；
或
分流模式信息包括：分流模式主从模式，第一网络为主网络，第二网络为从网络；
或
分流模式信息包括：分流模式为最小时延模式，第一网络的时延比第二网络的时延小。
在本申请实施例中，可以根据策略规则中的分流模式信息区分第一网络和第二网络，然后按照前述几个实施例的方法分别对第一资源和第二资源进行不同配置，从而可以实现对第一资源和第二资源更合理的配置。
另外需要说明的是，分流模式信息不仅用于区分第一网络和第二网络，还可以用于指示终端设备和第三核心网网元选择第一网络中的接入网设备和/或第二网络中的接入网设备进行业务流数据的传输。
当分流模式为优先级模式时，若第一网络的优先级高于第二网络的优先级，终端设备和第三核心网网元将优先选择第一网络中的接入网设备对GBR QoS flow对应的业务流数据进行传输，当GBR QoS flow对应的部分业务流数据不能通过第一网络中的接入网设备进行传输时，可以选择第二网络中的接入网设备对GBR QoS flow对应的该部分业务流数据进行传输，当GBR QoS flow对应的全部业务流数据不能通过第一网络中的接入网设备进行传输时，可以选择第二网络中的接入网设备对GBR QoS flow对应的全部业务流数据进行传输。
而当分流模式为主从模式时，若第一网络为主网络，第二网络为从网络，终端设备和第三核心网网元将选择第一网络中的接入网设备对GBR QoS flow对应的业务流数据进行传输，而不论何种情况导致第一网络中的接入网设备不能传输GBR QoS flow对应的业务流数据，终端设备和第三核心网网元都会选择第二网络中的接入网设备对GBR QoS flow对应的 业务流数据进行传输，不会存在第一网络和第二网络同时传输BR QoS flow对应的业务流数据的情况。
类似地，当分流模式为最小时延模式时，若第一网络的时延比第二网络的时延小，终端设备和第三核心网网元将选择第一网络中的接入网设备对GBR QoS flow对应的业务流数据进行传输，而不论何种情况导致第一网络中的接入网设备不能传输GBR QoS flow对应的业务流数据，终端设备和第三核心网网元都会选择第二网络中的接入网设备对GBR QoS flow对应的业务流数据进行传输，不会存在第一网络和第二网络同时传输BR QoS flow对应的业务流数据的情况。
上面介绍了三种分流规则，可以理解的是，本申请实施例中的分流规则不限于上述三种分流规则，下面将以另一种分流规则为例，对第一核心网网元配置第一资源和第二资源的过程进行说明。
在本申请实施例提供的业务流的处理方法的第九实施例中，QoS规则包括保证流带宽的第一参数，分流规则包括分流模式信息，分流模式信息包括：分流模式为均衡模式，第一网络对应的保证流带宽与第二网络对应的保证流带宽的比例。
第一核心网网元根据策略规则为GBR QoS flow配置第一资源和第二资源包括：
第一核心网网元根据第一参数和比例配置第一资源中的保证流带宽和第二资源中的保证流带宽。
在本申请实施例中，分流模式为均衡模式，即终端设备和第三核心网网元将同时选择第一网络中的接入网设备和第二网络中的接入网设备传输GBR QoS flow对应的业务流数据，因此可以根据分流模式信息中的比例对第一参数进行分配，分别得到第一资源中的保证流带宽和第二资源中的保证流带宽。
上述实施例是对分流模式为均衡模式时，第一资源和第二资源的一个分配过程进行的说明，下面将对分流模式为均衡模式时，第一资源和第二资源的另一个分配过程进行说明。
本申请实施例提供的业务流的处理方法的第十实施例，QoS规则包括第一网络对应的保证流带宽的第一参数和第二网络对应的保证流带宽的第七参数，分流规则包括分流模式信息，分流模式信息包括：分流模式为均衡模式。
第一核心网网元根据策略规则为GBR QoS flow配置第一资源和第二资源包括：
第一核心网网元将第一资源中的保证流带宽配置为第一参数；
第一核心网网元将第二资源中的保证流带宽配置为第七参数。
在本申请实施例中，QoS规则指示了第一网络对应的保证流带宽和第二网络对应的保证流带宽，所以第一核心网网元可以直接根据QoS规则进行第一资源和第二资源中保证流带宽的设定，由于分流模式为均衡模式，所以不对第一参数和第七参数的相对大小进行限定。
根据前述内容可知，当第一网络中的接入网设备不能传输GBR QoS flow对应的业务流数据时，终端设备会通过第二网络中的接入网设备与终端设备传输GBR QoS flow对应的业务流数据，然而第一资源和第二资源存在差异，若不对第二资源进行调整，可能会影响GBR QoS flow对应的业务流数据的传输，例如，为了节约第二网络的资源，第二资源中的保证 流带宽往往较小，所以不能很好地保证GBR QoS flow对应的业务流数据的传输，因此需要对第二资源进行调整。下面将对第二资源的调整过程进行具体说明。
具体地，请参阅图5，本申请实施例中业务流的处理方法的第十一实施例示意图。如图5所示，本申请实施例提供了一种业务流的处理方法的第十一实施例，包括：
301，当第三核心网网元确定第一网络中的接入网设备不能传输GBR QoS flow对应的业务流数据时，第三核心网网元向第一核心网网元发送第一指示信息。
其中，第一指示信息用于指示第一网络中的接入网设备不能传输GBR QoS flow对应的业务流数据；
相应地，第一核心网网元会接收来自第三核心网网元的第一指示信息。
302，第一核心网网元根据第一指示信息将第二资源中的保证流带宽调整为第一参数。
可以理解的是，在前述的第三实施例至第八实施例中，在第一网络能够传输GBR QoS flow对应的业务流数据的情况下，对于任意模式，用于传输GBR QoS flow对应的业务流数据的保证流带宽均为第一参数，所以为了避免第二资源影响第二网络中的接入网设备传输GBR QoS flow对应的业务流数据，第一核心网网元将第二资源中的保证流带宽调整为第一参数，即维持用于传输业务流数据的保证流带宽不变。
303，第一核心网网元向第三核心网网元发送调整后的第二资源。
304、第一核心网网元向第二网络中的接入网设备发送调整后的第二资源。
305、第一核心网网元向终端设备发送调整后的第二资源。
在本申请实施例中，第一核心网网元发送调整后的第二资源的方式与前述第二实施例中发送第二资源的方式相同，具体可参照第二实施例中发送第二资源的相关说明进行理解。
相应地，第三核心网网元会接收来自第一核心网网元的调整后的第二资源；当终端设备确定第一网络中的接入网设备不能传输GBR QoS flow对应的业务流数据时，终端设备也接收来自第一核心网网元的调整后的第二资源。
306，第三核心网网元根据调整后的第二资源通过第二网络中的接入网设备向终端设备发送GBR QoS flow对应的业务流数据。
307，终端设备根据调整后的第二资源通过第二网络中的接入网设备向第三核心网网元发送GBR QoS flow对应的业务流数据。
在本申请实施例中，第一核心网网元将第二资源中的保证流带宽调整为第一参数，使得第三核心网网元和终端设备采用调整后的第二资源进行业务流数据的传输，从而可以避免第二资源不足而影响业务流数据的传输。
在上述实施例中，是将第第二资源中的保证流带宽调整为第一参数，然而在前述的第九实施例中，由于分流模式为均衡模式，并且QoS规则中包含了第一网络对应的保证流带宽的第一参数和第二网络对应的保证流带宽的第七参数，所以在第一网络能够传输GBR QoS flow对应的业务流数据的情况下，用于传输GBR QoS flow对应的业务流数据的保证流带宽为第一参数和第七参数的和。这种情况下，第一核心网网元重新配置第二资源的过程则有不同。下面将对该情况下，第一核心网网元重新配置第二资源的过程进行介绍。
具体地，请参阅图6，本申请实施例中业务流的处理方法的第十二实施例示意图。如 图6所示，本申请实施例提供了一种业务流的处理方法的第十二实施例，包括：
401，当第三核心网网元确定第一网络中的接入网设备不能传输GBR QoS flow对应的业务流数据时，第三核心网网元向第一核心网网元发送第一指示信息。
其中，第一指示信息用于指示第一网络中的接入网设备不能传输GBR QoS flow对应的业务流数据；
相应地，第一核心网网元会接收来自第三核心网网元的第一指示信息。
402，第一核心网网元根据第一指示信息将第二资源中的保证流带宽调整为第一参数与第七参数的和。
可以理解的是，将第二资源中的保证流带宽调整为第一参数与第七参数的和，可以维持用于传输业务流数据的保证流带宽不变。
403，第一核心网网元向第三核心网网元发送调整后的第二资源。
404，第一核心网网元向第二网络中的接入网设备发送调整后的第二资源。
405，第一核心网网元向终端设备发送调整后的第二资源。
相应地，第三核心网网元会接收来自第一核心网网元的调整后的第二资源；
当终端设备确定第一网络中的接入网设备不能传输GBR QoS flow对应的业务流数据时，终端设备也会接收来自第一核心网网元的调整后的第二资源。
406，第三核心网网元根据调整后的第二资源通过第二网络中的接入网设备向终端设备发送GBR QoS flow对应的业务流数据。
407，终端设备根据调整后的第二资源通过第二网络中的接入网设备向第三核心网网元发送GBR QoS flow对应的业务流数据。
需要说明的是，在本申请实施例中，除了操作402外，其余操作与第十实施例中的操作相同，具体可参照第十实施例中的操作进行理解。
在本申请实施例中，第一核心网网元将第二资源中的保证流带宽调整为第一参数和第七参数的和，使得第三核心网网元和终端设备采用调整后的第二资源进行业务流数据的传输，从而可以避免第二资源不足而影响业务流数据的传输。
基于上述分析可知，第二核心网网元会向第一核心网网元发送策略规则，以指示第一核心网网元为GBR QoS flow在第一网络和第二网络分配资源，而为了使第一核心网网元需要为GBR QoS flow在第一网络和第二网络分配资源，可以采用添加指示的方法，因此，在本申请实施例提供的一种业务流的处理方法的第十二实施例中，在第一核心网网元根据策略规则为保障流比特速率服务质量流GBR QoS flow在第一网络和第二网络分配资源之前，方法还包括：
第二核心网网元向第一核心网网元发送第二指示信息，第二指示用于指示第一核心网网元为GBR QoS flow在第一网络和第二网络分配资源。
需要说明的是，该第二指示信息可以由第二核心网网元单独向第一核心网网元发送，第二指示信息也可以携带在策略规则中。
相应地，第一核心网网元会获取该第二指示信息，而且，第一核心网网元会将该第二指示信息发送给第三核心网网元和终端设备。
所以，第三核心网网元会接收来自第一核心网网元的第二指示信息，终端设备也会接收来自第一核心网网元的第二指示信息。
这样，第三核心网网元和终端设备均能获得第一核心网网元为第一网络和第二网络为GBR QoS flow分配资源的信息，以指示第三核心网网元和终端设备对GBR QoS flow对应的业务流数据进行切换或移动。
为了更好地理解本申请实施例中业务流的处理方法，下面将以一应用例对该处理方法进行具体介绍，该应用例以建立MA PDU会话为场景，在该应用例中，第一核心网网元为SMF网元，第二核心网网元为PCF网元，第三核心网网元为UPF网元，此外，还包括终端设备、AMF网元和接入网设备，其中，终端设备用UE表示，第一网络中的接入网设备用RAN节点表示，第二网络中的机入网设备用AN节点表示。
请参阅图7，本申请实施例中业务流的处理方法的应用例示意图。如图7所示，在该应用例中，当需要建立MA PDU会话时，UE向AMF网元发送非接入层(Non-access stratum，NAS)消息，该NAS消息中包含MA PDU会话建立请求。然后AMF网元会将该MA PDU会话建立请求转发至SMF网元，SMF网元会发送会话管理策略关联建立请求SM policy association establishment request消息至PCF网元，SM policy association establishment request消息用于请求会话建立的策略规则。
然后，PCF网元会向SMF网元发送会话管理策略关联建立响应SM policy association establishment response消息，该SM policy association establishment response消息中包含策略规则。
此后，SMF网元与UPF网元之间建立N4会话，SMF通过N4会话向UPF网元发送第一资源、第二资源和分流规则。SMF网元还会发送两个N1N2MessageTransfer消息到AMF网元，其中一个N1N2MessageTransfer消息到AMF消息包含第一资源和分流规则，另一个N1N2MessageTransfer消息到AMF消息中包含第二资源和分流规则。
接着，AMF网元会向RAN节点和AN节点各发送一个N2PDU Session Request消息，RAN节点接收到的N2PDU Session Request消息中包含第一资源和分流规则，AN节点接收到的N2PDU Session Request消息中包含第二资源和分流规则。另外，AMF网元还会向UE发送分流规则。
最后，RAN节点根据第一资源与UE建立空口资源，在空口资源的建立过程中，UE会接收到来自RAN节点的第一资源。
同样地，AN节点根据第二资源与UE建立空口资源，在空口资源的建立过程中，UE会接收到来自AN节点的第二资源。
经过上述过程，GBR QoS flow建立完成。
之后，UE通过RAN节点与UPF进行业务流数据的传输；当RAN节点不可用时，UE会通过RN节点与UPF进行数据的传输，此外，UPF网元还会向SMF发送第一指示信息，然后SMF网元根据第一指示信息对第二资源进行调整，并通过N4会话将调整后的第二资源发送给UPF，使得UPF根据调整后的第二资源与UE进行数据的传输。
