一种控制业务流传输的方法、装置及系统
本申请要求于2019年09月29日提交国家知识产权局、申请号为201910937270.8、申请名称为“一种控制业务流传输的方法、装置及系统”，以及于2019年12月31日提交国家知识产权局、申请号为201911425198.7、申请名称为“一种控制业务流传输的方法、装置及系统”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
本申请实施例涉及通信技术领域，尤其涉及一种控制业务流传输的方法、装置及系统。
背景技术
为了应对无线宽带技术的挑战，保持第三代合作伙伴计划(3rd generation partnership project，3GPP)网络的领先优势，3GPP标准组制定了下一代移动通信网络架构(next generation system)，称为第五代(5-generation，5G)网络架构。该5G网络架构不但支持终端通过3GPP标准组定义的无线技术(如长期演进(long term evolution，LTE)，5G无线接入网(radio access network，RAN)等)接入5G核心网(core network，CN)而且支持非(non)-3GPP接入技术通过non-3GPP转换功能(interworking function，N3IWF)或下一代接入网关(next generation packet data gateway，ngPDG)接入核心网侧。
后续5G核心网除了支持无线接入以外还可以支持固定网络/有线网络的接入，如：5GC支持家庭网关(residential Gateway，RG)通过有线网络接入。在此场景下，当家庭网关除了支持固定/有线接入之外，还支持蜂窝接入时，这样的家庭网关为具有混合接入能力或多接入能力的用户终端设备。
在5G网络中，终端和数据网络(Date Network，DN)之间存在用于提供数据传输通道的分组数据单元(packet data unit，PDU)会话(session)。目前PDU会话中可以传输保证比特率(Guaranteed Bit Rate，GBR)业务流，也可以传输non-GBR业务流，每个会话对应一个第一最大聚合带宽(Aggregate Maximum Bit Rate，AMBR)和第一聚合最大带宽上限值(Total Maximum Bit Rate，TMBR)。然而，TMBR的引入会影响会话管理网元或用户面网元不明确如何控制业务流传输。
发明内容
本申请实施例提供一种控制业务流传输的方法、装置及系统，用以在为会话定义TMBR的情况下，实现满足第一接入技术要求的QoS参数控制需求。
为达到上述目的，本申请采用如下技术方案：
第一方面，本申请实施例提供一种控制业务流传输的方法，包括：会话管理网元获取在会话中通过第一接入技术传输的业务流的第一最大总带宽TMBR、和第一保证比特率GBR业务流的保证带宽；TMBR用于表示会话中通过第一接入技术传输的所有 业务流的带宽上限值；会话管理网元向数据面网元发送第一信息，第一信息用于数据面网元确定以下信息中的任一个或多个：所述会话的第一最大聚合带宽AMBR、所述会话中所述第一接入技术对应的第二AMBR、第一TMBR、第二TMBR，第二AMBR用于表示会话中通过第一接入技术传输的non-GBR业务流的聚合最大带宽上限。
本申请实施例提供一种控制业务流传输的方法，该方法中会话管理网元获取在会话中通过第一接入技术传输的业务流的第一TMBR、和第一GBR业务流的保证带宽，并向数据面网元发送第一信息，这样便于数据面网元确定会话的第一最大聚合带宽AMBR、所述会话中所述第一接入技术对应的第二AMBR、第一TMBR、第二TMBR。后续数据面网元可以根据第二AMBR、第一TMBR和第二TMBR中的至少一个控制会话中通过第一接入技术传输的业务流，这样可以满足第一接入技术要求的QoS参数控制需求。
在一种可能的实现方式中，第一信息包括以下信息中的任一个或多个：所述第一最大聚合带宽AMBR、第二AMBR和第二TMBR。这样可以由会话管理网元计算第二AMBR和第二TMBR中的任一个或多个，而省去数据面网元计算的步骤。即数据面网元可以直接使用第二AMBR和第二TMBR中的任一个或多个控制会话中的业务流。
在一种可能的实现方式中，第一信息还包括：第一接入技术指示或第一接入技术对应的隧道标识中的任一个或多个。这样便于数据面网元确定第二AMBR和第二TMBR中的任一个或多个与第一接入技术相关或者与第一接入技术对应的隧道相关。
在一种可能的实现方式中，本申请实施例提供的方法还包括：会话管理网元根据第一TMBR、以及第一GBR业务流的保证带宽，确定第二AMBR和第二TMBR中的至少一个。

在一种可能的实现方式中，会话管理网元根据第一TMBR、一个或多个GBR业务流的保证带宽总和，确定第二AMBR，包括：会话管理网元确定第二AMBR为第一TMBR与一个或多个GBR业务流的保证带宽总和之间的差值。也即会话管理网元直接将第一TMBR与一个或多个GBR业务流的保证带宽总和之间的差值作为第二AMBR。
在一种可能的实现方式中，本申请实施例提供的方法还包括：会话管理网元获取会话对应的第一AMBR，第一AMBR用于表示会话中所有non-GBR业务流的聚合最大带宽上限；相应的，会话管理网元根据第一TMBR、一个或多个GBR业务流的保证带宽总和，确定第二AMBR，包括：在第一TMBR与一个或多个GBR业务流的保证带宽总和之间的差值大于第一AMBR的情况下，会话管理网元确定第二AMBR为第一AMBR。或者，在第一TMBR与一个或多个GBR业务流的保证带宽总和之间的差 值小于或等于第一AMBR的情况下，会话管理网元确定第二AMBR为第一TMBR与一个或多个GBR业务流的保证带宽总和之间的差值。也即会话管理网元通过比较第一AMBR和(第一TMBR与所述一个或多个GBR业务流的保证带宽总和之间的差值)之间的关系，将二者中最小的确定为第二AMBR。
在一种可能的实现方式中，会话管理网元根据第一TMBR、以及第一GBR业务流的保证带宽，确定第二TMBR，包括：会话管理网元根据第一TMBR和第一接入技术对应的上行分类器上分流的一个或多个GBR业务流的保证带宽总和，确定第二TMBR。这样可以准确计算第二TMBR。示例性的，第二TMBR为第一TMBR减去第一接入技术对应的上行分类器上分流的一个或多个GBR业务流的保证带宽总和得到的差值。
在一种可能的实现方式中，本申请实施例提供的方法还包括：会话管理网元向第一接入技术对应的接入网网关发送会话的标识和以下信息中的任一个或多个：第二AMBR、第一TMBR。这样便于第一接入技术对应的接入网网关根据第二AMBR、第一TMBR控制会话中通过第一接入技术传输的业务流。
在一种可能的实现方式中，本申请实施例提供的方法还包括：会话管理网元向第一接入技术对应的上行分类器发送会话的第二AMBR或第一TMBR。这样便于第一接入技术对应的上行分类器确定控制业务流的参数。

在一种可能的实现方式中，第一信息包括以下信息中的任一个或多个：第一TMBR、第二TMBR、或会话中通过第一接入技术传输的一个或多个GBR业务流中每个GBR业务流的保证带宽。
应理解，第一方面中的会话管理网元可以由策略控制网元替换，当会话管理网元由策略控制网元替换时，策略控制网元计算第二AMBR和第二TMBR中的至少一个，策略控制网元可以通过会话管理网元向数据面网元发送第一信息，以及向其他节点(例如，接入网网关或接入网设备)发送相关参数。
在一种可能的实现方式中，本申请实施例提供的方法还包括：会话管理网元向数据面网元发送指示信息，该指示信息指示当在会话中通过第一接入技术传输的GBR业务流处于非激活态时，上述GBR业务流的保证带宽资源可以被通过第一接入技术传输的non-GBR业务流使用。具体来讲，该会话中通过第一接入技术传输的non-GBR业务流的第二AMBR为non-GBR业务流分配的目标第二AMBR与非激活态的GBR业务流的保证带宽值之和，或者第二AMBR为第一AMBR。这样可以在会话中没有GBR业务流传输时，使得non-GBR业务流充分利用该会话的带宽资源，保证了non-GBR业务流的可靠传输。上述目标第二AMBR为会话管理网元为non-GBR业务流计算的第二AMBR，由会话管理网关发送给数据面网元。
在一种可能的实现方式中，当目标第二AMBR与非激活态的GBR业务流的保证带宽值之和小于第一AMBR时，该第二AMBR为目标第二AMBR与非激活态的所述GBR业务流的保证带宽值之和。或者，当目标第二AMBR与非激活态的GBR业务流 的保证带宽值之和大于或等于第一AMBR时，第二AMBR为第一AMBR。可以保证在充分利用该会话的带宽资源时，又不会超过会话的最大带宽上限。

具体实施方式
在介绍本申请实施例之前，首先对本申请实施例涉及到的相关名词进行解释：
1)、会话，如图2所示，即会话管理网元建立的连通终端和用户面网元到达数据网络的数据传输通道。
2)、多接入会话，即该会话可以支持多种接入技术。如图2所示，会话A可以通过第一接入技术接入核心网侧，也可以通过第二接入技术接入核心网侧。以会话为分组数据单元(packet data unit，PDU)会话为例，多接入会话即(multi-access PDU session，MA-PDU)。
3)、单接入会话，即该会话支持一种接入技术。例如，本申请实施例的单接入会话指该会话支持第一接入技术。也即该会话可以通过第一接入技术接入核心网侧。
4)、终端-最大聚合带宽(aggregate maximum bit rate，AMBR)，为终端粒度参数，也可以称为终端AMBR(UE-AMBR)，用以表示终端所有non-GBR(non-guaranteed bit rate)业务流的聚合最大带宽上限。
5)、会话-最大聚合带宽(session-aggregate maximum bit rate，Session-AMBR)，为会话粒度参数，用以表示单个会话中所有non-GBR业务流的聚合最大带宽上限。
6)、业务流保证带宽(guaranteed bit rate，GBR)，为业务流粒度参数，用以表示具体业务流网络侧可以为其提供的保证带宽值，即最小传输带宽值，分为上行和下行保证带宽值。适用于GBR业务流。与其相关的，当一条或多条GBR业务流汇聚成一条服务质量(Quality of Service，QoS)流(flow)时，此QoS flow的保证带宽值为上述GBR业务流保证带宽值之和，定义为GFBR(Guaranteed Flow Bit Rate)。所以GFBR为QoS flow粒度参数。
7)、业务流最大带宽(maximum bit rate，MBR)，为业务流粒度参数，用以表示具体业务流网络侧可以为其提供的最大带宽值，分为上行和下行最大带宽值。适用于GBR业务流。与其相关的，当一条或多条GBR业务流汇聚成一条QoS flow时，此QoS flow的最大带宽值为上述GBR业务流最大带宽值之和，定义为MFBR(Maximum Flow Bit Rate)。所以MFBR为QoS flow粒度参数。
8)、会话最大总带宽(session total maximum bit rate，Session-TMBR)，为会话粒度参数，用以表示某会话中通过第一接入技术传输的所有业务流(例如，GBR业务流和non-GBR业务流)的聚合最大带宽上限值。
为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。例如，第一接入技 术和第二接入技术仅仅是为了区分不同的接入技术，并不对其先后顺序进行限定。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
需要说明的是，本申请中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
本申请中，“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b，或c中的至少一项(个)，可以表示：a，b，c，a-b，a-c，b-c，或a-b-c，其中a，b，c可以是单个，也可以是多个。
本申请实施例的技术方案可以应用于各种通信系统，例如：码分多址(code division multiple access，CDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single carrier FDMA，SC-FDMA)和其它系统等。术语“系统”可以和“网络”相互替换。3GPP在长期演进(long term evolution，LTE)和基于LTE演进的各种版本是使用E-UTRA的UMTS的新版本。5G通信系统、新空口(new radio，NR)是正在研究当中的下一代通信系统，及non3GPP接入系统，如WLAN接入(WLAN access network)，有线接入(Wireline access network)等。此外，通信系统还可以适用于面向未来的通信技术，都适用本申请实施例提供的技术方案。
本申请实施例描述的系统架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。

其中，在图3a中，本申请实施例中一个或者多个终端30中存在至少一个终端与用户面网元20之间具有会话，且该会话可以为支持第一接入技术的单接入会话。
本申请实施例中一个终端可以具有一个或多个会话，该一个或多个会话中每个会话对应一个第一AMBR(Session-AMBR)，每个终端有一个终端AMBR(UE-AMBR)，non-GBR业务流必须满足所在会话的第一AMBR，接入网网关可以对一个终端的所有会话进行整理。
如图3b所示，图3b示出了本申请实施例提供的一种控制业务流传输的方法所应用的通信系统，图3b与图3a的区别在于，在图3b中终端30通过不同的接入技术接入无线网络，例如，终端30可以通过支持第一接入技术的接入网网关40和支持第二接入技术的接入网设备50与核心网中的网元通信。
在一种可选的实现方式中，图3b所示的通信系统还可以包括：第二接入技术对应的上行分类器70，上行分类器70还用于根据第一AMBR控制通过第二接入技术传输的业务流。
应理解，在图3b中第二接入技术对应的上行分类器70和第一接入技术对应的上行分类器60可以是同一个上行分类器，此时，该上行分类器即可以对通过第一接入技术传输的业务流进行分流，也可以对第二接入技术对应的业务流进行分流。

其中，会话管理网元10用于负责用户发起业务时网络侧建立相应的会话，为终端30提供具体服务，尤其是基于会话管理网元10与用户面网元20之间的接口向用户面网元20下发数据包转发策略、QoS策略等。
其中，用户面网元20为用户面网关，主要负责分组数据包的转发、服务质量(Quality of Service，QoS)控制、计费信息统计等。例如，用户面数据通过用户面网元20传输到数据网络。数据网络用于为终端30提供服务，如提供移动运营商业务，Internet服务或第三方服务等。
例如，以图3a或图3b所示的通信系统应用于4G核心网为例，该会话管理网元10可以为移动管理实体(mobility management entity，MME)。用户面网元20可以为分组数据网用户面((PGW-User Plane，PGW-U)和服务网关用户面(SGW-User Plane，SGW-U)。
例如，若图3a或图3b所示的通信系统应用于5G网络，则如图4a或图4b所示，会话管理网元10所对应的网元或者实体可以为会话管理功能(session management function，SMF)网元、用户面网元20即对于5G中的用户面功能(user plane function，UPF)网元。

具体的，如图5所示，终端在使用non-3GPP接入技术接入接入和移动性管理功能网元时，可以通过非3GPP互通功能(non-3GPP interworking function，N3IWF)实体接入接入和移动性管理功能网元。当3GPP与non-3GPP属于相同PLMN时，终端选择相同接入和移动性管理功能网元。当3GPP与non-3GPP属于不同PLMN时，可以选择不同的接入和移动性管理功能网元。
会话管理功能网元由接入和移动性管理功能网元选择，不同的会话可以选择不同的会话管理功能网元，但相同的会话要选择相同的会话管理功能网元。会话管理功能网元可以为会话选择用户面功能网元，一个会话可以有多个用户面功能网元，所以会话管理功能网元可能会选择多个用户面功能网元为某会话创建隧道连接。

需要指出的是，本申请各实施例之间可以相互借鉴或参考，例如，相同或相似的步骤，方法实施例和装置实施例之间，均可以相互参考，不予限制。
本申请实施例中的GBR业务流可以在一种接入技术中传输，例如，在第一接入技术或第二接入技术中传输，或者，GBR业务流也可以同时在多种技术传输，例如，在第一接入技术和第二接入技术中传输。non-GBR业务流可以在一种接入技术传输，或者，同时在多种技术传输例如，在第一接入技术和第二接入技术中传输。下面以GBR业务流在一种接入技术传，non-GBR业务流在多种技术传输为例。
如图1所示，每个PDU会话对应一个第一AMBR＝10Mbps，每个终端有一个终端AMBR＝50Mbps，non-GBR业务流必须满足所在会话的第一AMBR，接入网设备会对一个终端的所有会话进行整理，以该终端的会话中传输GBR业务流1＝5Mbps，以及GBR业务流2＝20Mbps为例，其中，GBR业务流1在第二接入技术中传输，GBR业务流2在第一接入技术中传输。图1示出了各节点对于QoS参数的处理情况。终端和用户面网元主要基于第一AMBR控制non-GBR业务流的聚合带宽，基于GBR业务流1＝5Mbps控制GBR业务流1的保证带宽，基于GBR业务流2＝20Mbps控制GBR业务流2的保证带宽。接入网设备基于激活的各会话的第一AMBR计算当前的终端AMBR值，从而控制终端的non-GBR业务流的聚合带宽，基于GBR业务流1＝5Mbps控制GBR业务流1的保证带宽。
当会话为多接入会话时，同一会话业务流可以同时在多种接入技术传输。针对GBR业务流，由于每个处理节点都基于保证带宽值为此GBR业务流预留了带宽资源， 因此，GBR业务流的带宽可以得到端到端的保证。但针对non-GBR业务流，可以同时在多种技术传输，且QoS控制是会话粒度及终端粒度的带宽聚合值。因此，接入侧(NG-RAN，N3G网关)的聚合带宽值之和与两端(终端，用户面网元)的聚合带宽值不同。例如上图1中，接入网设备侧和接入网网关上的第一AMBR分别为10Mbps，那么两者之和就是20Mbps，而终端，用户面网元上述此会话的第一AMBR聚合值只为10Mpbs。
其次，当第一接入技术为有线接入技术(wireline access)时，除了上述QoS参数需要执行之外，还有另一个专门针对有线接入的QoS参数，Session-TMBR(Session Total Maximum Bit Rate)，用以表示通过有线接入技术传输的某会话所有业务流(GBR业务流，non-GBR业务流)的聚合最大带宽上限值。由于MA PDU会话中GBR业务流可以在第一接入技术和第二接入技术侧移动，包括GBR业务流整体切换到另一接入技术，或GBR业务流的部分数据切换到另一接入技术，而第一TMBR又与GBR业务流当前是否在第一接入技术侧已经占用了部分带宽有关，所以给第一接入技术侧的QoS控制带来困难。
基于此，本申请实施例提供一种控制业务流传输的方法，该方法通过会话管理网元获取在会话中通过第一接入技术传输的业务流的第一TMBR、和第一GBR业务流的保证带宽，并向用户面网元发送第一信息，这样便于用户面网元确定第一接入技术对应的第二最大聚合带宽AMBR和第二TMBR中的至少一个，并根据第二AMBR和第二TMBR中的至少一个控制会话中通过第一接入技术传输的业务流，这样可以满足第一接入技术要求的QoS参数控制需求。
在本申请实施例中，一种控制业务流传输的方法的执行主体的具体结构，本申请实施例并未特别限定，只要可以通过运行记录有本申请实施例的一种控制业务流传输的方法的代码的程序，以根据本申请实施例的一种控制业务流传输的方法进行通信即可，例如，本申请实施例提供的一种控制业务流传输的方法的执行主体可以是会话管理网元中能够调用程序并执行程序的功能模块，或者为应用于会话管理网元中的通信装置，例如，芯片。本申请实施例提供的一种控制业务流传输的方法的执行主体可以是用户面网元中能够调用程序并执行程序的功能模块，或者为应用于用户面网元中的通信装置，例如，芯片。本申请对此不进行限定。下述实施例以一种控制业务流传输的方法的执行主体为用户面网元、会话管理网元为例进行描述。
结合上述图3a和图3b，如图7所示，本申请实施例提供一种控制业务流传输的方法，该方法以数据面网元为用户面网元20为例，该方法包括：
步骤701、会话管理网元10获取在会话中通过第一接入技术传输的业务流的第一TMBR、和第一GBR业务流的保证带宽。TMBR用于表示会话中通过第一接入技术传输的所有业务流的聚合带宽上限值。
本申请实施例中第一GBR业务流的保证带宽可以指会话中通过第一接入技术传输的所有GBR业务流(至少包括激活的一个或多个GBR业务流)中每个GBR业务流的保证带宽，上述每个GBR业务流的保证带宽值可以基于PCF网元发送的QoS策略获取，或者基于会话管理网元的本地策略获取。当上述GBR业务流同时在第二接入技术和第一接入技术传输时，第一GBR业务流的保证带宽只包含此GBR业务流通过第 一接入技术传输的数据所占用的保证带宽值。或者，本申请实施例中第一GBR业务流的保证带宽可以指会话中通过第一接入技术传输的激活的一个或多个GBR业务流中每个GBR业务流的保证带宽。
本申请实施例中的第一TMBR为：为PCF网元发送的Session-TMBR，或者UDM网元发送的签约的session-TMBR。第一GBR业务流的保证带宽为：为PCF发送的QoS策略中的包含的保证带宽，或者基于本地策略获取的保证带宽。会话管理网元10可以从PCF网元处获取第一GBR业务流的保证带宽，或者PCF网元基于本地配置的策略确定第一GBR。当上述GBR业务流在第一与第二接入技术同时传输时，会话管理网元10从PCF网元获取此GBR业务流的保证带宽值，会话管理网元10基于上述保证带宽值确定此GBR业务流的第一GBR业务流保证带宽为通过第一接入技术传输的保证带宽。当然，本申请实施例中会话管理网元10可以从PCF网元处获取会话中通过第一接入技术传输的一个或多个GBR业务流中部分GBR业务流的保证带宽，此外，会话管理网元10基于本地配置的策略确定一个或多个GBR业务流中其余部分GBR业务流的保证带宽。
例如，会话管理网元10可以从PCF网元处获取会话中通过第一接入技术传输的GBR业务流1的保证带宽为10M，会话管理网元10基于本地配置的策略确定会话中通过第一接入技术传输的GBR业务流2的保证带宽为5M。
具体的，会话管理网元10从UDM网元中获取中的签约数据。终端的签约数据中包括：针对第一接入技术的第一TMBR(即第一Session-TMBR，以下描述简写为第一TMBR)。可选的，会话管理网元10将上述参数(例如，针对第一接入技术的第一TMBR发送给PCF网元，PCF网元基于策略对上述参数进行授权，如PCF网元根据策略对上述参数做进一步修改。PCF网元修改后，会话管理网元10将修改后的参数作为第一TMBR，即从PCF网元获取第一TMBR。
举例说明，本申请实施例中涉及到的会话可以为：PDU会话，或者公用数据网(public data network，PDN)连接。以会话为PDU会话为例，本申请实施例中的PDU会话指：会话管理网元10建立的连通终端30和用户面网元20到达DN的数据传输通道。该数据传输通道中涉及到的网元包括：终端、接入网设备、以及由会话管理网元10为该会话选择的用户面网元20。该数据传输通道中包括多个相邻两个网元之间的链路。例如，包括终端和接入网设备之间的链路、接入网设备和用户面网元20之间的链路、以及UPF网元和DN之间的链路。
可以理解的是，本申请实施例在步骤701之前，还可以包括：会话管理网元10确定管理(例如，建立或更新)终端的会话。例如，终端向会话管理网元10发起会话管理流程，同现有技术。例如，会话管理流程可以包括：会话建立流程或者会话更新(也可以称为会话修改)流程。上述会话管理流程也可以用来建立或更新MA PDU会话，同时支持第一接入技术与第二接入技术传输。即终端向会话管理网元10发送PDU session establishment request，或者PDU session modification request消息。
本申请实施例中的会话为支持第一接入技术的单接入会话，或者，会话为支持第一接入技术和第二接入技术的多接入会话。
步骤702、会话管理网元10向用户面网元20发送第一信息，以使得用户面网元 20接收来自会话管理网元10的第一信息。该第一信息用于用户面网元20确定以下信息中的任一个或多个：所述会话的第一最大聚合带宽AMBR、所述会话中所述第一接入技术对应的第二最大聚合带宽AMBR、所述第一TMBR、所述第二TMBR。其中，第二AMBR用于表示会话中通过第一接入技术传输的non-GBR业务流的聚合最大带宽上限。
例如，会话管理网元10向用户面网元20发送N4消息，以使得用户面网元20接收来自会话管理网元的N4消息。该N4消息中携带第一信息。
本申请实施例中的第二AMBR为：实际传输时网络侧允许该会话中通过第一接入技术传输的non-GBR业务流的聚合最大带宽上限，也即实际传输时该会话中传输的non-GBR业务流的可用聚合最大带宽。第二TMBR为：实际传输时网络侧允许该会话中通过第一接入技术传输的所有non-GBR业务流和所有GBR业务流的带宽上限值。
本申请实施例中的第二AMBR和第一AMBR可以相等，或者第二AMBR小于第一AMBR。第二TMBR和第一TMBR可以相等，或者第二TMBR小于第一TMBR。
本申请实施例中第一信息用于用户面网元20确定会话中第一接入技术对应的第二AMBR和第二TMBR中的至少一个可以包括如下两种情况：1)、第一信息包括第二AMBR和第二TMBR中的至少一个，这样即由会话管理网元10计算第二AMBR和第二TMBR中的至少一个，并向用户面网元20发送第二AMBR和第二TMBR中的至少一个。2)、第一信息包括用于计算第二AMBR的参数，这样用户面网元20基于用于计算第二AMBR的参数自主计算第二AMBR。例如，用于计算第二AMBR的参数可以为第一TMBR和会话中通过第一接入技术传输的一个或多个GBR业务流中每个GBR业务流的保证带宽。或者用于计算第二AMBR的参数可以为第二TMBR和会话中通过第一接入技术传输的一个或多个GBR业务流中每个GBR业务流的保证带宽。
步骤703、用户面网元20根据第二AMBR、第一TMBR和第二TMBR中的至少一个，控制在会话中通过第一接入技术传输的业务流。例如，业务流包括通过第一接入技术传输的所有non-GBR业务流，和/或，通过第一接入技术传输的所有GBR业务流。
应理解，用户面网元20可以根据第二AMBR，控制在会话中通过第一接入技术传输的所有non-GBR业务流。用户面网元20可以根据第二AMBR和第二TMBR，控制在会话中通过第一接入技术传输的GBR业务流、non-GBR业务流。具体的，第二AMBR控制non-GBR业务流，第二TMBR控制GBR业务流和non-GBR业务流。用户面网元20可以根据第二TMBR或第一TMBR控制在会话中采用所述第一接入技术传输的所有GBR业务流与non-GBR业务流的聚合带宽之和小于或等于所述第一TMBR或第二TMBR。
本申请实施例提供一种控制业务流传输的方法，该方法中会话管理网元获取在会话中通过第一接入技术传输的业务流的第一TMBR、和第一GBR业务流的保证带宽，并向用户面网元发送第一信息，这样便于用户面网元确定第一接入技术对应的第二AMBR、第一TMBR和第二TMBR中的至少一个。后续用户面网元可以根据第二AMBR、第一TMBR和第二TMBR中的至少一个控制会话中通过第一接入技术传输的业务流，这样可以满足第一接入技术要求的QoS参数控制需求。
本申请实施例中第二AMBR可以由用户面网元20计算，第二AMBR和第二TMBR也可以由会话管理网元10计算，计算第二AMBR和/或第二TMBR的执行主体不一样，具体实现过程存在差异，下述将分别介绍：
示例1)、由会话管理网元10计算第二AMBR和第二TMBR任意一个或多个。
在一种可能的实现方式中，本申请实施例中的第一信息包：以下信息中的任一个或多个：所述第一最大聚合带宽AMBR、第二AMBR和所述第二TMBR。或者，本申请实施例中的第一信息包括：第二TMBR。或者本申请实施例中的第一信息包括：第二AMBR和第二TMBR。本申请实施例中的第一信息包括：第一AMBR。或者本申请实施例中的第一信息包括：第二AMBR、第一AMBR以及第二TMBR。
在一种可选的实现方式中，该第一信息还可以包括：第一接入技术指示或第一接入技术对应的隧道标识。其中，第一接入技术指示用于指示采用第一接入技术传输。第一接入技术对应的隧道标识用于确定第一接入技术对应的隧道。
应理解，第一信息包括第一接入技术指示和第二AMBR之间的对应关系，和/或，第一接入技术指示和第二TMBR之间的对应关系。或者，第一信息包括第一接入技术对应的隧道标识和第二AMBR之间的对应关系，和/或，第一接入技术对应的隧道标识和第二TMBR之间的对应关系。
其中，第一接入技术指示和第二AMBR之间的对应关系表示该会话通过第一接入技术指示的第一接入技术传输的non-GBR业务流的最大聚合带宽为第二AMBR。或者，第一接入技术对应的隧道标识和第二AMBR之间的对应关系表示相关隧道标识指示的隧道中传输的non-GBR业务流的最大聚合带宽为第二AMBR。
如图8所示，在一种可能的实施例中，本申请实施例提供的方法在步骤702之前还包括：
步骤704、会话管理网元10根据第一TMBR、以及第一GBR业务流的保证带宽，确定第二AMBR和第二TMBR中的至少一个。
示例I：作为第一种可能的实现方式，会话管理网元10根据第一TMBR、以及第一GBR业务流的保证带宽，确定第二AMBR可以通过以下步骤7041和步骤7042实现：
步骤7041、会话管理网元10根据第一GBR业务流的保证带宽，确定会话中通过第一接入技术传输的一个或多个GBR业务流的保证带宽总和。
应理解，本申请实施例中会话中可以存在通过第一接入技术传输的一个或多个GBR业务流，一个或多个GBR业务流中每个GBR业务流对应一个第一GBR业务流的保证带宽，不同GBR业务流对应的第一GBR业务流的保证带宽可以相同，也可以不相同，本申请实施例对此不作限定。该一个或多个GBR业务流即为该会话中通过第一接入技术传输的所有激活的GBR业务流。一个或多个GBR业务流的保证带宽总和即为一个或多个GBR业务流对应的第一GBR业务流的保证带宽的累加。
本申请实施例涉及到的激活的GBR业务流可以指：正在进行的GBR业务流，用户面网元为此GBR业务流建立了用户面通道，并预留了相应的带宽资源。
步骤7042、会话管理网元10根据第一TMBR、一个或多个GBR业务流的保证带宽总和，确定第二AMBR。
示例性的，步骤7042可以通过以下方式实现：会话管理网元10确定第二AMBR为第一TMBR与一个或多个GBR业务流的保证带宽总和之间的差值。也即会话管理网元10使用第一TMBR减去一个或多个GBR业务流的保证带宽总和，得到第二AMBR。换句话说：即第二AMBR为第一TMBR与会话中通过第一接入技术传输的一个或多个GBR业务流的保证带宽总和之间的差值。
举例说明，第一TMBR为100Mbps，激活的一个或多个GBR业务流包括GBR业务流1的保证带宽为30Mbps，GBR业务流2的保证带宽为20Mbps，则会话管理网元10确定所述第二AMBR为100Mbps-30Mbps-20Mbps＝50Mbps。
示例II：
在第二种可能的实施例中，如图8所示，本申请实施例提供的方法在步骤704之前，还可以包括：
步骤705、会话管理网元10获取会话对应的第一AMBR，该第一AMBR用于表示会话中所有non-GBR业务流的聚合最大带宽上限。该第一AMBR可以由会话管理网元10从终端的签约数据中获取，也可以由会话管理网元10从PCF网元处获取，本申请实施例对此不作限定。
相应的，会话管理网元10根据第一TMBR、以及第一GBR业务流的保证带宽，确定第二AMBR，可以通过以下步骤7043实现：
步骤7043、会话管理网元10根据第一TMBR、一个或多个GBR业务流的保证带宽总和，以及第一AMBR，确定第二AMBR。
示例性的，会话管理网元10比较第二AMBR与第一AMBR的大小，会话管理网元10将第二AMBR与第一AMBR中的最小值作为最终的第二AMBR。即如果第一TMBR与所述一个或多个GBR业务流的保证带宽总和之间的差值大于整个会话的第一AMBR，则用第一AMBR作为第二AMBR。否则，如果第一TMBR与一个或多个GBR业务流的保证带宽总和之间的差值小于或等于整个会话的第一AMBR，则用第一TMBR与一个或多个GBR业务流的保证带宽总和之间的差值作为第二AMBR。
具体的，第一TMBR与一个或多个GBR业务流的保证带宽总和之间的差值小于第一AMBR时，会话管理网元10确定第二AMBR为所述第一TMBR与所述一个或多个GBR业务流的保证带宽总和之间的差值。或者，所述第一TMBR与所述一个或多个GBR业务流的保证带宽总和之间的差值大于第一AMBR，会话管理网元10确定第二AMBR为第一AMBR。换句话说，即第一TMBR与会话中通过第一接入技术传输的一个或多个GBR业务流的保证带宽总和之间的差值大于第一AMBR，第二AMBR为第一AMBR。
需要说明的是，示例I和示例II的区别在于，在示例I中会话管理网元10未比较第一AMBR，与第一TMBR减去一个或多个GBR业务流的保证带宽总和得到的差值，也即直接将第一TMBR减去一个或多个GBR业务流的保证带宽总和得到的差值作为第二AMBR。在示例II中，会话管理网元10将第一TMBR与一个或多个GBR业务流的保证带宽总和之间的差值和第一AMBR作比较，以确定第二AMBR。
如果会话为多接入会话，当第一TMBR减去一个或多个GBR业务流的保证带宽总和得到的差值小于第一AMBR的情况下，会话管理网元10发起GBR业务流切换流 程，将会话中通过第一接入技术传输的部分GBR业务流切换到第二接入技术中传输，以使得第二AMBR大于或等于第一AMBR。然后，会话管理网元10便可以只发送第一AMBR给用户面网元。同批注2场景。
此外，如果通过上述GBR业务流的调整仍然不能使得第二AMBR大于第一AMBR，则会话管理网元10发送指示给PCF网元。上述指示用来表示第二AMBR小于第一AMBR，即该会话中通过第一接入技术传输的non-GBR业务流的带宽上限值小于整个会话的non-GBR业务流的带宽上限。则PCF网元基于上述指示更新分流模式。如发送priority-based分流模式，用以表示优先将第一接入技术的带宽占满后，其余业务流从第二接入技术传输。
如果会话为多接入会话，当第一TMBR减去一个或多个GBR业务流的保证带宽总和得到的差值大于第一AMBR的情况下，会话管理网元10向用户面网元发送第一AMBR。不用发送第二AMBR。相应的，步骤703可以通过以下方式实现：用户面网元使用第一AMBR控制该会话中通过第一接入技术和第二接入技术传输的non-GBR业务流。
本申请实施例中，会话管理网元10根据第一TMBR、以及第一GBR业务流的保证带宽，确定第二TMBR可以通过以下方式实现：
步骤7044、会话管理网元10根据第一TMBR和第一接入技术对应的上行分类器上分流的一个或多个GBR业务流的保证带宽总和，确定第二TMBR。
示例性的，本申请实施例中的步骤7044可以通过以下方式具体实现：会话管理网元10根据第一TMBR减去第一接入技术对应的上行分类器上分流的一个或多个GBR业务流的保证带宽总和，确定第二TMBR。换句话说，第二TMBR为第一TMBR和所述第一接入技术对应的上行分类器上分流的所述一个或多个GBR业务流的保证带宽总和之间的差值。
本申请实施例中业务流经过上行分类器到达用户面网元(如锚点用户面网元)之前，上行分类器可以分流部分GBR业务流，该部分被分流的GBR业务流从上行分类器直接到外网，而不再经过用户面网元(如锚点用户面网元)。
相应的，如图8所示，本申请实施例提供的方法在步骤703之前还可以包括：
步骤706、会话管理网元10向用户面网元20发送会话对应的第一AMBR，以使得用户面网元20接收来自会话管理网元10的会话对应的第一AMBR。
其中，第一AMBR可以和第一TMBR、以及第一GBR业务流的保证带宽携带在同一个消息中由会话管理网元10向用户面网元20发送。或者，携带第一AMBR的消息和携带第一TMBR、以及第一GBR业务流的保证带宽的消息不同。
相应的，本申请实施例中的步骤703可以通过以下步骤7031和/或步骤7032实现：
步骤7031、用户面网元20根据第二AMBR控制在会话中通过第一接入技术传输的所有non-GBR业务流。
示例性的，本申请实施例中的步骤7031具体可以通过以下方式实现：用户面网元20控制会话中通过所述第一接入技术或第一接入技术对应的隧道传输的non-GBR业务流的带宽之和小于或等于第二AMBR。
可选的，如果本申请实施例提供的方法还包括：用户面网元20获取第一AMBR， 则步骤7031可以通过以下方式实现：此外，如果会话为多接入会话，则用户面网元20还可以控制会话中通过第一接入技术传输的所有non-GBR业务流的带宽总和与第二接入技术传输的所有non-GBR业务流的聚合带宽总和之和小于或等于第一AMBR。
步骤7032、用户面网元20控制在会话中通过第一接入技术传输的所有non-GBR业务流和所有GBR业务流的带宽之和小于或等于第二TMBR。
举例说明，第二TMBR为500Mbps，通过第一接入技术传输的所有non-GBR业务流和所有GBR业务流的带宽总和小于或等于500Mbps。
需要说明的是，如果用户面网元20接收到来自会话管理网元10的第二AMBR，用户面网元20可以直接使用第二AMBR控制non-GBR业务流。如果用户面网元20接收到来自会话管理网元10的第二TMBR，而不包括第二AMBR，则1)用户面网元20需要用第二TMBR计算出第二AMBR，然后执行步骤7031。例如，用户面网元20使用第二TMBR减去一个或多个GBR业务流的保证带宽总和得到第二AMBR。或者2)用户面网元20直接执行步骤7031，即不计算第二AMBR，而采用第二TMBR控制在会话中通过第一接入技术传输的所有non-GBR业务流和所有GBR业务流。
示例2)、由用户面网元20计算第二AMBR。
相应的，本申请实施例中的第一信息包括：第一TMBR或第二TMBR。此外，第一信息还可以包括会话中通过第一接入技术传输的一个或多个GBR业务流中每个GBR业务流的保证带宽。或者，第一信息包括第一TMBR、或第二TMBR。此外，第一信息还可以包括会话中通过第一接入技术传输的一个或多个GBR业务流的保证带宽总和。如果会话管理网元发送的是一个或多个GBR业务流的保证带宽总和，则后续可以省略用户面网元20根据每个GBR业务流的保证带宽，确定一个或多个GBR业务流的保证带宽总和的过程。
如图9所示，如果第一信息包括第一TMBR或第二TMBR，作为本申请的再一种可能的实施例，本申请实施例提供的方法在步骤703之前还可以包括：
步骤707、用户面网元20根据第一TMBR或第二TMBR、一个或多个GBR业务流中每个GBR业务流的保证带宽，确定第二AMBR。
作为一种可能的实现，本申请实施例中的步骤707可以通过以下方式具体实现：用户面网元20根据每个GBR业务流的保证带宽，确定一个或多个GBR业务流的保证带宽总和。用户面网元20确定第二AMBR为第一TMBR与一个或多个GBR业务流的保证带宽总和之间的差值。或者，用户面网元20确定第二AMBR为第二TMBR与一个或多个GBR业务流的保证带宽总和之间的差值。
作为另一种可能的实现，本申请实施例中的步骤707可以通过以下方式具体实现：如果用户面网元20获取到第一AMBR，则第一TMBR或第二TMBR中任一个与一个或多个GBR业务流的保证带宽总和之间的差值大于第一AMBR，用户面网元20确定第二AMBR为第一AMBR。第一TMBR或/第二TMBR与一个或多个GBR业务流的保证带宽总和之间的差值小于第一AMBR，用户面网元20确定第二AMBR为第一TMBR或第二TMBR中任一个与一个或多个GBR业务流的保证带宽总和之间的差值。
作为再一种可能的实现，本申请实施例中的步骤707可以通过以下方式具体实现：或者，用户面网元20确定第二AMBR为小于第一差值的任意值。第一差值为第一 TMBR或/第二TMBR与一个或多个GBR业务流的保证带宽总和之间的差值。
如图9所示，本申请实施例中的步骤703具体可以通过以下方式实现：用户面网元20控制会话中采用第一接入技术传输的所有non-GBR业务流的聚合带宽之和小于或等于第二AMBR。
如果用户面网元20接收到的第一信息包括第一TMBR或第二TMBR，在用户面网元20不计算第二AMBR的情况下，本申请实施例中的步骤703具体可以通过以下方式实现：用户面网元20控制所述会话中采用所述第一接入技术传输的所有GBR业务流与non-GBR业务流的聚合带宽之和小于或等于所述第一TMBR或第二TMBR。
如果该会话为多接入会话，用户面网元20基于第二AMBR，第一TMBR或第二TMBR中的至少一个为业务流选择接入技术。具体的，用户面网元20基于分流模式选择第一接入技术传输业务流，但如果业务流超过第二AMBR，第一TMBR或第二TMBR中任一个的带宽上限值，则用户面网元20选择第二接入技术传输业务流。避免通过第一接入技术传输时，由于带宽受限导致丢包。举例说明，比如分流模式指示选择最小往返时间(Round-Trip Time，RTT)的链路传输，用户面网元20检测3GPP与non-3GPP的链路RTT，如果第一接入技术对应的链路的RTT小于第二接入技术对应的链路的RTT，则用户面网元20基于分流模式应该选择第一接入技术传输业务流。但如果此时第一接入技术对应的带宽不足以支撑此业务流，则用户面网元20仍然选择第二接入技术传输业务流。
示例性的，分流模式可以包括：负载均衡指示、激活链路与备选链路指示、最优链路指示、链路最小时延指示、RTT指示、链路最低负载指示、链路最大带宽指示、接入信号最强指示中的至少一个参数。
需要说明的是，如果在用户面网元20基于分流模式为non-GBR业务流选择一个接入技术之后，如果non-GBR业务流在会话中传输的聚合带宽之和大于第二AMBR，则用户面网元20可以为non-GBR业务流重新选择接入技术。如果业务流在会话中传输的聚合带宽之和大于第一TMBR或第二TMBR可以对non-GBR业务流或GBR业务流选择接入技术。
作为一种可能的实现，本申请实施例提供的方法还包括：会话管理网元10向用户面网元20发送指示信息，用以指示用户面网元20基于第二AMBR，第一TMBR或第二TMBR中的至少一个为业务流选择接入技术。
作为再一种可能的实施例，如图9所示，本申请实施例提供的方法还包括：
步骤708、用户面网元20向第一接入技术对应的接入网网关40和上行分类器60发送第二AMBR，以使得接入网网关40和上行分类器60接收来自用户面网元20的第二AMBR。
可选的，步骤708可以通过以下方式实现：用户面网元20向会话管理网元10发送第一消息，以由会话管理网元10转发第一消息至第一接入技术对应的接入网网关40和上行分类器60。该第一消息中包括向第一接入技术对应的接入网网关40和上行分类器60发送的第二AMBR。
步骤709、接入网网关40或上行分类器60将第二AMBR与之前存储的第二AMBR或第一AMBR值比较，采用其中最小值作为最终控制non-GBR业务流的最大聚合带 宽参数。
作为再一种可能的实施例，如图9所示，本申请实施例提供的方法还包括：
步骤710、用户面网元20向第二接入技术对应的接入网设备50和上行分类器70发送Session R-AMBR，以使得接入网网关40和上行分类器60接收来自用户面网元20的Session R-AMBR。
步骤711、接入网设备50或上行分类器70采用Session R-AMBR控制业务流。上述Session R-AMBR为所述PDU会话中通过第二接入技术传输的所有non-GBR业务流最大聚合带宽参数。
再一种可能的实施例中，如果该通信系统中还包括第一接入技术对应的上行分类器60，以及第二接入技术对应的上行分类器70，结合图3a或图3b，如图8或图9所示，本申请实施例提供的方法还包括：
步骤712、会话管理网元10向第一接入技术对应的上行分类器60发送会话的用于计算第二AMBR的信息，以使得上行分类器60接收用于计算第二AMBR的信息。
例如，用于计算第二AMBR的信息包括以下信息中的任一个或多个：第二AMBR、第一AMBR、第一TMBR。
示例性的，会话管理网元10向上行分类器60发送N4会话标识、第二AMBR，用以表示此N4会话对应的会话的通过第一接入技术传输的所有non-GBR业务流的最大聚合带宽为第二AMBR。本申请实施例中的会话标识和N4会话标识一一对应。
示例性的，会话管理网元10向上行分类器60发送第一TMBR，上行分类器60基于第一TMBR与当前激活的至少一个GBR业务流的保证带宽总和计算第二AMBR。即第二AMBR＝第一TMBR-当前激活的至少一个GBR业务流的保证带宽总和。
示例性的，会话管理网元10向上行分类器60发送第一AMBR与第一TMBR，上行分类器60基于第一TMBR与当前激活的至少一个GBR业务流的保证带宽总和计算第二AMBR。即第二AMBR＝第一TMBR-当前激活的至少一个GBR业务流的保证带宽总和。上行分类器60比较第一AMBR与上述差值的大小关系。如果第一AMBR小于或等于上述差值，则第二AMBR＝第一AMBR。
步骤713、上行分类器60使用第二AMBR控制在该会话中传输的non-GBR业务流，即通过第一接入技术传输的non-GBR业务流带宽之和小于第二AMBR。
步骤714、会话管理网元10向第二接入技术对应的上行分类器70发送会话的第一AMBR，或者发送一个或多个GBR业务流的保证带宽。
步骤715、上行分类器70根据第一AMBR，或者发送一个或多个GBR业务流的保证带宽控制该会话中传输的业务流。
具体的，上行分类器70控制该会话中传输的所有non-GBR业务流(包括通过第一接入技术传输的与通过第二接入技术传输的所有non-GBR业务流)的AMBR之和不超过第一AMBR。或者上行分类器70控制一个或多个GBR业务流满足各自的保证带宽。
需要说明的是，本申请实施例中的步骤712-步骤715适用于会话为多接入会话的场景，也适用于单接入会话中存在上行分类器的场景。
作为在一种可选的实施例，如图8或图9所示，本申请实施例提供的方法还可以 包括：
步骤716、会话管理网元10向终端发送第一信息。
具体的，步骤716可以通过以下方式实现：会话管理网元10确定会话建立或更新完成后，向终端发送会话建立成功消息(PDU session establishment accept)或会话更新指令(PDU session modification command)。其中，PDU session establishment accept或PDU session modification command包含以下信息中的任一个或多个：第二AMBR和第一TMBR。用以表示此会话，通过第一接入技术传输的non-GBR业务流的聚合最大带宽值为第二AMBR，通过第一接入技术传输的所有GBR与non-GBR业务流的带宽值之和小于等于第一TMBR。可选的，上述消息中还包含第一接入技术指示，用以表示上述第二AMBR或第一TMBR是第一接入技术相关的参数。
应理解，当第二AMBR或TMBR参数本身即包含接入技术指示时，第一接入技术指示为可选参数。即接收方接收到了第二AMBR或TMBR便可以确定其为与第一接入技术关联的参数，此时，第一接入技术指示或第一接入技术对应的隧道标识便可以省略。
步骤717、终端根据第二AMBR和第一TMBR中的至少一个控制该会话中传输的业务流。
例如，步骤717可以通过以下方式实现：终端该会话中控制通过第一接入技术传输的non-GBR业务流的最大聚合带宽值不超过第二AMBR，和/或，终端控制该会话中通过第一接入技术传输的non-GBR业务流的最大聚合带宽值与通过第一接入技术传输的GBR业务流的保证带宽值之和不超过(即小于或等于)第一TMBR。
作为在一种可选的实施例，如图8或图9所示，本申请实施例提供的方法还可以包括：
步骤718、会话管理网元10向第一接入技术对应的接入网网关40发送用于计算第二AMBR的信息，以使得接入网网关40接收来自会话管理网元10的用于计算第二AMBR的信息。
例如，用于计算第二AMBR的信息包括以下信息中的任一个或多个：第二AMBR、第一TMBR。
示例性的，会话管理网元10向接入网网关40发送N2消息(N2information)，以使得接入网网关40接收来自会话管理网元10的N2消息。其中，N2消息中包括：会话的标识以及以下信息中的任一个或多个：第二AMBR、第一TMBR。这样接入网网关40便可以确定会话的标识关联的会话中所有non-GBR业务流的聚合最大带宽值的上限为第二AMBR，所有业务流的带宽值之和小于或等于第一TMBR。
示例性的，如果用于计算第二AMBR的信息包括第一TMBR，则接入网网关40基于第一TMBR与当前激活的一个或多个GBR业务流的保证带宽总和计算第二AMBR。即Session第二AMBR＝第一TMBR–当前激活的一个或多个GBR业务流的保证带宽总和。
步骤719、接入网网关40将该终端所有激活会话的第一AMBR之和作为终端AMBR。
步骤720、接入网网关40使用终端AMBR(UE-AMBR)或会话TMBR中的至少 一个进行业务流的QoS控制。
示例性的，步骤720可以通过以下方式实现：接入网网关40控制在该终端的所有激活的会话中传输的所有non-GBR业务流的聚合最大带宽值之和小于或等于终端AMBR，通过第一接入技术传输的所有业务流带宽之和小于或等于会话TMBR。再一种可能的实施例中，结合图3b，如图8或图9所示，本申请实施例提供的方法还包括：

示例性的，会话管理网元10向第二接入技术对应的接入网设备发送N2消息，以使得接入网设备接收N2消息。N2消息中携带会话的标识和第一AMBR。
步骤722、接入网设备50将该终端所有激活的会话的第一AMBR之和作为终端AMBR，进行QoS控制。
示例性的，步骤722可以通过以下方式实现：接入网设备控制该终端的所有non-GBR业务流的聚合最大带宽值之和小于或等于接入网设备确定的终端AMBR。例如，终端所有激活的会话包括PDU会话1和PDU会话2，PDU会话1的第一AMBR为20Mbps，PDU会话2的第一AMBR为5Mbps，则接入网设备确定的终端AMBR为25Mbps。这样接入网设备需要控制在终端所有激活的会话中传输的所有non-GBR业务流之和小于或等于25Mbps。
作为在一种可选的实施例，如图8或图9所示，本申请实施例提供的方法还可以包括：
步骤723、会话管理网元10根据第一AMBR以及第二AMBR计算第二接入技术侧的Session R-AMBR。
其中，Session R-AMBR表示会话粒度的AMBR。表示通过第二接入技术传输的所有non-GBR业务流的聚合最大带宽上限。
示例性的，步骤723可以通过以下方式实现：Session R-AMBR＝第一AMBR-第二AMBR。
步骤724、会话管理网元10向接入网设备50发送Session R-AMBR，以使得接入网设备50接收来自会话管理网元的Session R-AMBR。接入网设备基于Session R-AMBR控制通过第二接入技术传输的所有non-GBR业务流，即通过第二接入技术传输的所有non-GBR业务流带宽值之和小于或等于Session R-AMBR。
在一种可选的实现方式中，本申请实施例提供的方法还包括：会话管理网元10向用户面网元发送Session R-AMBR与第二接入技术指示，或者Session R-AMBR与第二接入技术隧道信息。此外，会话管理网元10向用户面网元发送第一AMBR，同现有技术，用以表示此会话的所有non-GBR业务流(包括在第一接入技术和第二接入技术传输的业务流)的聚合最大带宽值。
需要说明的是，本申请实施例图7-图9中所有由用户面网元执行的动作也可以由终端执行，也即用户面网元可以由终端替换。
需要说明的是，图7或图8中所有由会话管理网元10执行的动作可以由PCF网元替换，当由PCF网元替换会话管理网元时，PCF网元可以通过会话管理网元执行相 关的发送动作。举例说明，以会话为多接入会话为例，在由会话管理网元计算的场景中，如图10所示，会话管理网元10从UDM网元处获取第一AMBR＝20Mbps，终端AMBR＝50Mbps，第一TMBR＝20Mbps，会话管理网元10从PCF网元处获取GBR业务流1的保证带宽＝5Mbps。该GBR业务流1在第一接入技术侧传输。因此，会话管理网元10基于第一TMBR与GBR业务流1的保证带宽＝5Mbps计算第一接入技术侧的第二AMBR＝15Mbps。会话管理网元10向接入网设备50发送终端AMBR＝50Mbps，以及第一AMBR＝20Mbps，会话管理网元10向接入网网关40发送终端AMBR＝50Mbps，GBR业务流1的保证带宽＝5Mbps，以及第二AMBR＝15Mbps或/和第一TMBR＝20Mbps。会话管理网元10向终端发送第一AMBR＝20Mbps、第二AMBR＝15Mbps或/和第一TMBR＝20Mbps，GBR业务流1的保证带宽＝5Mbps。会话管理网元10向用户面网元发送第一AMBR＝20、第二AMBR＝15Mbps或/和第一TMBR＝20Mbps，GBR业务流1的保证带宽＝5Mbps。会话管理网元10向接入网网关对应的上行分类器60发送GBR业务流1的保证带宽＝5Mbps。这样终端和用户面网元可以基于第二AMBR＝15Mbps控制在第一接入技术侧传输的non-GBR业务流，从而可以使得该会话中传输的GBR业务流1和non-GBR业务流不超过第一TMBR＝20Mbps。
举例说明，例如，以会话中传输GBR业务流2和GBR业务流1，其中，GBR业务流1保证带宽＝5Mbps在接入网网关对应的上行分类器60处分流，则会话管理网元10可以确定第二TMBR＝20Mbps-GBR业务流1保证带宽＝15Mbps。GBR业务流2保证带宽＝8Mbps通过用户面网元20路由。
举例说明，以会话为多接入会话为例，在由用户面网元计算的场景中，如图11所示，会话管理网元10从UDM网元处获取第一AMBR＝20Mbps，终端AMBR＝50Mbps，第一TMBR＝20Mbps，会话管理网元10从PCF网元处获取GBR业务流1的保证带宽＝5Mbps，会话管理网元10向用户面网元10发送第一AMBR＝20bps、GBR业务流1的保证带宽＝5Mbps、第一TMBR＝20Mbps。GBR业务流1在第一接入技术侧传输，因此，用户面网元20基于第一TMBR＝20Mbps与GBR业务流1的保证带宽＝5Mbps计算第一接入技术侧的第二AMBR＝15Mbps，计算第二接入技术对应的第二AMBR＝5Mbps。会话管理网元10向接入网设备50发送终端AMBR＝50Mbps，以及Session-R-AMBR＝5Mbps。用户面网元20向接入网网关40发送第二AMBR＝15Mbps。会话管理网元10向接入网网关40终端AMBR＝50Mbps，GBR业务流1的保证带宽＝5Mbps。会话管理网元10向终端发送第一AMBR＝10bps、第一接入技术对应的第二AMBR＝15Mbps与第二接入技术对应的第二AMBR＝5Mbps，GBR业务流1的保证带宽＝5Mbps。会话管理网元10向接入网网关40对应的上行分类器60发送第一GBR业务流1的保证带宽＝5Mbps。
在一种可能的实施例中，如图8或图9所示，本申请实施例提供的方法还包括：
步骤725、会话管理网元向用户面网元发送指示信息，以使得用户面网元接收来自会话管理网元的指示信息。该指示信息指示当在会话中通过第一接入技术传输的GBR业务流处于非激活态时，会话中通过第一接入技术传输的non-GBR业务流的第二AMBR为non-GBR业务流分配的目标第二AMBR与非激活态的GBR业务流的保证带宽值之和，或者第二AMBR为第一AMBR。
其中，会话中通过第一接入技术传输的GBR业务流处于非激活态可以理解为：通过第一接入技术传输的GBR业务流没有在该会话中传输。
步骤726、用户面网元根据指示信息确定第二AMBR为所述non-GBR业务流分配的目标第二AMBR与非激活态的所述GBR业务流的保证带宽值之和，或者所述第二AMBR为所述第一AMBR。
在一种可能的实现方式中，当目标第二AMBR与非激活态的GBR业务流的保证带宽值之和小于第一AMBR时，第二AMBR为目标第二AMBR与非激活态的GBR业务流的保证带宽值之和。
在一种可能的实现方式中，当目标第二AMBR与非激活态的GBR业务流的保证带宽值之和大于或等于所述第一AMBR时，第二AMBR为第一AMBR。
第二AMBR也表示与第二AMBR处于同一传输通道的GBR业务流处于非激活态时，上述非激活态的GBR业务流的带宽资源可以被non-GBR业务流使用。即会话管理网元通过向用户面网元发送指示信息，以使得用户面网元确定当会话中通过第一接入技术传输的GBR业务流处于非激活态时，处于非激活态的GBR业务流的带宽资源可以被non-GBR业务流使用。即non-GBR业务流可以达到的最大带宽值第二AMBR等于为non-GBR业务流分配的第二AMBR与非激活态的GBR业务流或非激活的GBR QoS flow的保障带宽值之和。
可选的，会话管理网元还向用户面网元发送(指示信息与第一接入技术指示的对应关系)或(指示信息与第一接入技术对应的隧道标识的对应关系)或者指示信息为第二AMBR或资源动态调整指示中的任一个或多个给用户面网元，用以指示针对第一接入技术对应的隧道或隧道标识对应的隧道侧，当GBR业务流处于非激活态时，此GBR业务流带宽资源可以被non-GBR业务流占用。
举例说明，为会话1中通过第一接入技术传输的non-GBR业务流分配的目标第二AMBR为10M，会话1中为GBR业务流分配的带宽资源为5M，当GBR业务流在会话1中未传输时，则用户面网元可以确定会话1中non-GBR业务流的第二AMBR为10M+5M＝15M。如果第二AMBR为15M大于或等于会话1的第一AMBR＝13M，则non-GBR业务流的第二AMBR＝会话1的第一AMBR＝13M。如果第二AMBR为15M小于会话1的第一AMBR＝20M，则non-GBR业务流的第二AMBR＝15M。
