本申请涉及通信技术领域，尤其涉及服务质量(Quality of Service，QoS)控制的方法、设备及系统。
背景技术
在现有网络架构中，对于非独立网(non-standalone)架构存在双连接(dual connectivity，DC)的场景。终端支持DC是指终端可以在同一时刻接入两个接入设备，这两个接入设备中一个接入设备称为主接入设备或第一接入设备，另一个接入设备称为辅接入设备或第二接入设备。在第五代移动通信系统(5th generation system，5GS)的网络架构中，终端可以同时接入两个接入设备，这两个接入设备一个是下一代节点B(next generation node B，gNB)，一个是演进型基站(evolved NodeB，eNodeB或eNB)，可以将5GS中的DC称为多无线接入技术双连接(multi-radio access technology dual connectivity，MR-DC)。
其中，在MR-DC场景中会存在一些扩展的QoS信息，如扩展的接入点粒度(Access Point name，APN)最大聚合比特率(per APN-aggregate maximum bit rate，APN-AMBR)，扩展的保证比特率(guaranteed bit rate，GBR)或者扩展的最大比特率(maximum bit rate，MBR)等，用于支持使用新空口(new radio，NR)接入gNB进行数据传输，最高速率理论值可以达到4T比特每秒(bits per second，bps)。而若终端只使用演进通用陆地无线接入网(evolved universal terrestrial radio access network，E-UTRAN)技术接入eNB，最高速率理论值只能达到10Gbps。
然而目前，针对上述DC场景，无法对通过eNB传输的承载或者通过gNB传输的QoS流的信息(如最大带宽等)进行调整。这样，在MR-DC场景下，高带宽用户可能会挤占其他用户的带宽，导致其他用户无法正常使用。同时反之，低带宽用户可能得不到及时的带宽提升，从而会影响用户体验。因此，如何在DC场景下如何实现QoS控制是目前亟待解决的问题。

具体实施方式
为了方便理解本申请实施例的技术方案，首先给出本申请相关技术的简要介绍如下。
第一，GBR和非GBR(non-GBR)：
GBR是指网络系统保证承载的最小比特速率，即使在网络资源紧张的情况下，相应的比特速率也能够保持。MBR参数定义了GBR承载在资源充足的条件下，能够达到的速率上限。其中，MBR的数值有可能大于或等于GBR的数值。
相反的，非GBR指的是在网络拥挤的情况下，业务(或者承载)需要承受降低速率的要求。由于非GBR承载不需要占用固定的网络资源，因而可以长时间地建立。而GBR承载一般只是在需要时才建立。
第二，APN-MMBR和终端设备(user equipment，UE)-AMBR：
其中，APN-AMBR是关于某个APN连接的、所有非GBR承载的比特速率总和的上限。UE-AMBR是关于某个UE的、所有APN连接的、所有非GBR承载的比特速率总和的上限。如APN1-AMBR就是关于APN1连接的所有非GBR承载的比特速率总和的上限，APN2-AMBR就是关于APN2连接的所有非GBR承载的比特速率总和的上限。若某个UE的所有APN连接包括上述APN1连接和APN2连接，则UE-AMBR可以等于APN2-AMBR与APN2-AMBR的和。
第三，5G非独立组网架构：
现有的5G非独立组网架构有多种部署方式，可以分为选择option3、option 4、和option7。
其中，option3包括三种类型的架构，分为option 3、option 3a、option 3x，分别如图1中的(a)、(b)和(c)所示。可以看出，option3三种架构的共同点在于：主接入设备为eNB，辅接入设备为NR节点(node)；终端可以向演进的分组核心网(evolved packet core，EPC)中的核心网设备发送EPC非接入层(non-access stratum，NAS)信令；终端可以通过长期演进(long term evolution，LTE)-Uu接口与eNB通信，eNB可以通过S1-移动性管理实体(mobility management entity，MME)接口接入EPC。终端可以与NR节点通信，NR节点可以与eNB通信。区别点在于，在图1的 (a)中，eNB还可以通过S1-U接口接入EPC；在图1的(b)中，eNB和NR节点均可以通过S1-U接口接入EPC；在图1的(c)中，NR节点通过S1-U接口接入EPC。其中，这里的EPC为第四代(4th generation，4G)核心网，这里的S1-U接口为用户面接口，S-MME接口为控制面接口。
其中，option4包括两种类型的架构，分为option 4、option 4a，分别如图2中的(a)和(b)所示。可以看出，option4两种架构的共同点在于：主接入设备为NR节点，辅接入设备为演进的(evolved)eNB；终端可以通过下一代(next generation，NG)1接口与下一代核心网(NG core，NGC)中的核心网设备通信；终端可以与演进的eNB和NR节点通信；NR节点可以通过NG2接口和NG3接口接入NGC；NR节点可以与演进的eNB通信。区别点在于，在图2的(b)中，演进的eNB还可以通过NG3接口接入NGC。其中，这里的NGC为5G核心网，这里的NG2接口为控制面接口，NG3接口为用户面接口。
其中，option7包括两种类型的架构，分为option 7、option 7a，分别如图3中的(a)和(b)所示。可以看出，option7两种架构的共同点在于：主接入设备为演进的eNB，辅接入设备为NR节点；终端可以通过NG1接口与NGC中的核心网设备通信；终端可以与演进的eNB和NR节点通信；演进的eNB可以通过NG2接口和NG3接口接入NGC；NR节点可以与演进的eNB通信。区别点在于，在图3的(b)中，NR节点还可以通过NG3接口接入NGC通信。其中，这里的NGC为5G核心网，这里的NG2接口为控制面接口，NG3接口为用户面接口。
综上，非独立组网架构的不同部署方式下，主接入设备或辅接入设备与核心网设备通过不同的接口连接。
第四，MR-DC架构：
图4为本申请实施例提供的与上述option3对应的一种MR-DC架构。其中，图4中的gNB可以对应上述option3中的NR节点。在图4中，E-UTRAN中的eNB可以与EPC中的核心网设备之间存在S1接口；eNB与gNB之间存在X2接口；eNB与eNB之间存在X2接口；gNB与gNB之间存在X2-U接口。其中，这里的X2接口可以包括X2-C接口和X2-U接口，其中，X2-C接口为控制面接口，X2-U接口为用户面接口。这里的S1接口包括S1-MME接口和S1-U接口，其中，S1-MME接口为控制面接口，S1-U接口为用户面接口。此外，对于上述option 3a和option 3x，gNB与EPC中的核心网设备之间存在S1-U接口。
图5为本申请实施例提供的与上述option4对应的一种MR-DC架构。其中，图5中的gNB可以对应上述option4中的NR节点。在图5中，gNB可以与NGC中的核心网设备之间存在NG2接口或NG3接口；演进的eNB与gNB之间存在Xn接口；演进的eNB与演进的eNB之间存在Xn-U接口；gNB与gNB之间存在Xn接口。其中，这里的Xn接口可以包括Xn-U接口和Xn-C接口，其中，Xn-C接口为控制面接口，Xn-U接口为用户面接口。可选的，演进的eNB与NGC中的核心网设备之间存在NG3接口。其中，gNB为5G接入网中的主接入设备，演进的eNB为5G接入网中的辅接入设备。
图6为本申请实施例提供的与上述option7对应的一种MR-DC架构。在图6中，演进的eNB可以与NGC中的核心网设备之间存在NG2或NG3接口；演进的eNB与 gNB之间存在Xn接口；演进的eNB与演进的eNB之间存在Xn接口；gNB与gNB之间存在Xn-U接口。其中，这里的Xn接口可以包括Xn-U接口和Xn-C接口，其中，Xn-C接口为控制面接口，Xn-U接口为用户面接口。可选的，gNB与NGC中的核心网设备之间存在NG3接口。其中，演进的eNB为5G接入网中的主接入设备，gNB为5G接入网中的辅接入设备。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。其中，在本申请的描述中，除非另有说明，“/”表示前后关联的对象是一种“或”的关系，例如，A/B可以表示A或B；本申请中的“和/或”仅仅是一种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这三种情况，其中A,B可以是单数或者复数。并且，在本申请的描述中，除非另有说明，“多个”是指两个或多于两个。“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。另外，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。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。
此外，本申请实施例描述的网络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。
现有技术中，针对DC场景，无法对通过eNB传输的承载或者通过gNB传输的QoS流的信息(如最大带宽等)进行调整。这样，在MR-DC场景下，若一个承载的带宽设置为扩展的带宽(即可以通过gNB传输)，而其他承载的带宽设置为非扩展的带宽(即可以通过eNB传输)。则当通过gNB传输的信号减弱，该承载的发送速率需要减弱时，若该承载设置的带宽未修改，仍为大带宽承载，数据传输速率很高，则将导致优先级低于该承载的其他非扩展带宽承载可能会得不到任何机会收发数据。也就是说，该承载可能会挤占其他用户的带宽，导致其他用户无法正常使用。同时反之，低带宽用户可能得不到及时的带宽提升，从而会影响用户体验。为解决上述问题，本申请实施例提供如下QoS控制的方法、设备及系统，用于在DC场景下实现QoS控制。
如图7所示，为本申请实施例提供的一种通信系统70。该通信系统70包括主接入设备701、移动管理网元702和分组数据网关703。移动管理网元702和分组数据网关703之间可以直接通信，也可以通过其他设备的转发进行通信，本申请实施例对此不作具体限定。

分组数据网关703，还用于将第一QoS参数发送至移动管理网元702。
移动管理网元702，用于接收来自分组数据网关703的第一QoS参数，并向主接入设备701发送第二QoS参数。其中，第二QoS参数与第一QoS参数相同，或者第二QoS参数是根据第一QoS参数获得的。
主接入设备701，用于接收来自移动管理网元702的第二QoS参数，其中，第二QoS参数用于对RAT对应的网络中的承载进行QoS控制。
基于本申请实施例提供的通信系统，由于分组数据网关可以根据用于指示承载使用的RAT的指示信息和承载的标识，获取与RAT对应的承载的第一QoS参数，该第一QoS参数或者根据该第一QoS参数获得的第二QoS参数用于对RAT对应的网络中的承载进行QoS控制。也就是说，可以在DC场景下实现QoS控制，通过核心网设备对承载的QoS参数进行调整，因此可以为承载分配合适的QoS参数，进而使承载在不同的接入设备上稳定、高效的传输，从而可以保证用户体验。
或者，可选的，基于图7所示的通信系统，另一种可能的实现方式中，主接入设备701，用于向移动管理网元702发送指示信息，该指示信息用于指示网络系统支持双连接。

移动管理网元702，用于接收来自分组数据网关703的第一QoS参数和第二QoS参数，并向主接入设备701发送第三QoS参数和第四QoS参数。其中，第三QoS参数与第一QoS参数相同，或者第三QoS参数是根据第一QoS参数获得的。第四QoS参数与第二QoS参数相同，或者第四QoS参数是根据第二QoS参数获得的。
主接入设备701，用于接收来自移动管理网元702的第三QoS参数和第四QoS参数，并在确定承载由第一RAT对应的网络传输的情况下，根据第三QoS参数对第一RAT对应的网络中的承载进行QoS控制；或者，在确定承载由第二RAT对应的网络传输的情况下，根据第四QoS参数对第二RAT对应的网络中的承载进行QoS控制。
需要说明的是，本申请实施例中的双连接可以是两个RAT对应的连接或者两个以上的RAT技术对应的连接，在此统一说明，以下不再赘述。
基于本申请实施例提供的通信系统，由于主接入设备可以获取来自分组数据网关的与双连接上第一RAT对应的承载的第三QoS参数、以及与双连接上第二RAT对应的承载的第四QoS参数，并在确定承载由第一RAT对应的网络传输的情况下，根据第三QoS参数对第一RAT对应的网络中的承载进行QoS控制；或者，在确定承载由第二RAT对应的网络传输的情况下，根据第四QoS参数对第二RAT对应的网络中的承载进行QoS控制。也就是说，可以在DC场景下实现QoS控制，通过核心网设备对 承载的QoS参数进行调整，因此可以为承载分配合适的QoS参数，进而使承载在不同的接入设备上稳定、高效的传输，从而可以保证用户体验。
可选的，图7所示的通信系统可以应用于如图1所示的option 3架构，此时如图8所示，分组数据网关701所对应的网元或者实体可以为EPC中的分组数据网络(packet data network，PDN)网关(PDN gateway，PGW)，移动管理网元702所对应的网元或者实体可以为EPC中的MME，主接入设备所对应的网元或者实体可以为option 3架构中的eNB。此外，如图8所示，EPC中还可以包括策略与计费规则功能(policy and charging rules function，PCRF)网元、服务网关(serving gateway，SGW)以及归属签约用户服务器(home subscriber server，HSS)等，具体可参考现有的EPC架构，在此不再赘述。

主接入设备901，用于接收来自会话管理网元902的QoS参数，其中，该QoS参数用于对RAT对应的网络中的QoS流进行QoS控制。
基于本申请实施例提供的通信系统，由于会话管理网元可以根据用于指示QoS流使用的RAT的指示信息和QoS流的标识，获取与RAT对应的QoS流的QoS参数，该QoS参数用于对RAT对应的网络中的QoS流进行QoS控制。也就是说，可以通过核心网设备对QoS流的QoS参数进行调整，进而在DC场景下实现QoS控制。因此可以为QoS流分配合适的QoS参数，进而使QoS流在不同的接入设备上稳定、高效的传输，从而可以保证用户体验。
