用户设备最大带宽的控制方法及装置、计算机存储介质
相关申请的交叉引用
本申请基于申请号为201710064620.5、申请日为2017年02月04日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及通信领域，尤其涉及一种用户设备最大带宽的控制方法及装置、计算机存储介质。
背景技术
在第四代(4G，The 4th Generation)移动通信系统中，将具有相同服务质量(QoS，Quality of Service)要求的数据流聚合成承载，用户面网元比如基站、网关对QoS的处理都是以承载作为最小粒度。4G系统QoS方案涉及的主要网元如图1所示，其中，主要网元的功能如下：
终端(UE，User Equipment)，主要通过无线空口接入4G网络并获得服务，终端通过空口和基站交互信息，通过非接入层信令(NAS，Non-Access-Stratum，)和核心网的移动管理实体交互信息；
基站(eNode B)，负责终端接入网络的空口资源调度以及空口的连接管理；
移动管理实体(MME，Mobility Management Entity)，也即核心网控制面实体，主要负责对用户的鉴权、授权以及签约检查，以保证用户是合法用户；对用户进行移动性管理，包括：位置注册和临时标识分配；维护用户的空闲(IDLE)和连接(CONNECT)状态以及状态迁移；在CONNECT 状态下的切换；分组数据网络(PDN，Packet Data Network)连接以及承载的维护，包括创建、修改和删除等会话管理的功能；
服务网关(SGW，Serving Gateway)：也即核心网用户面功能实体，主要负责漫游情况下和分组数据网网关(PGW，PDN GW)的交互；对用户IDLE状态下收到的下行数据包进行缓存并通知MME寻呼用户；具有跨基站的用户面锚点以及跨第二代(2G，2nd Generation)移动通信技术、第三代(3G，The 3rd Generation)移动通信技术、4G移动性的用户面锚点等功能；
分组数据网网关(PGW，PDN GW)，也即核心网用户面功能实体，是终端接入PDN网络的接入点，负责分配用户IP地址，网络触发的承载建立、修改和删除，还具有QoS控制计费等功能，是用户在第三代合作伙伴计划(3GPP，3rd Generation Partnership Project)系统内以及和非3GPP系统之间切换的锚点，从而保证IP地址不变，以保证业务连续性；
策略控制实体(PCRF，Policy and Charging Rules Function)，也即策略与计费规则功能单元，负责对无线承载的QoS策略控制以及计费策略控制。
4G QoS参数包括：QoS类别标识(QCI，QoS Class Identifier)和分配和保留优先级(ARP，Allocation and Retention Priority)，QoS参数可以唯一标识一个承载。QCI是一个标准化标识，每个QCI都对应一组QoS参数，包括：保证速率(GBR，Guaranteed Bit Rate)或非保证速率(non GBR)、优先级(priority)、延迟要求(Packet Delay Budget)以及丢包率(Packet Error Loss Rate)等参数。ARP标识用于当过负荷的时候，指示本承载被删除或保留的优先级。
针对non GBR承载，4G网络采用聚合最大比特率(AMBR，Aggregate Maximum Bit Rate)进行控制。AMBR包括：UE的所有non GBR承载聚合最大比特率(UE-AMBR)和用户在接入点名字(APN，Access Point Name) 上对应的non GBR承载聚合最大比特率(APN-AMBR)。其中下行的APN-AMBR在P-GW执行，上行的APN-AMBR在UE上执行，此外还在P-GW进行校验。eNode B执行UE-AMBR，而用于基站执行的UE-AMBR是MME根据如下公式计算获得执行UE-AMBR＝Min(签约UE-AMBR，Sum(激活的APN-AMBR))。其中，签约的UE-AMBR是MME从HSS的签约数据中获得，而MME也会累加所有激活的APN对应的APN-AMBR。
目前业界正在开展下一代无线通讯系统的研究，即5G移动通信技术。图2为5G的架构示意图，主要功能实体的功能如下：
基站，负责终端接入网络的空口资源调度以及空口的连接管理；
接入和移动性管理功能(AMF，Access and Mobility Management Function)主要负责接入认证、授权以及移动性管理。
会话管理功能(SMF，Session Management Function)主要负责会话管理、IP地址分配。
用户面功能(UPF，User Plane Function)为外部协议数据单元(PDU，Protocol Data Unit)会话的连接点，负责分组数据的路由、转发，以及对分组数据的策略执行等。
策略功能(PCF，Policy Function)主要负责策略决策。
在5G系统中同样需要对UE访问的Non GBR业务进行带宽的控制。目前，现有技术中提出了对PDU会话进行带宽控制的AMBR和UE-AMBR，但是基站如何获取用于执行的UE-AMBR还是一个需要解决的问题。

步骤701，PCF向SMF发送策略更新请求消息，消息中携带PDU session AMBR1’；
步骤702，SMF返回确认消息；
步骤703，SMF向AMF发送PDU流更新请求消息，携带PDU session AMBR1’；
步骤704，AMF向基站发送修改PDU流请求消息，消息中携带授权的PDU Session AMBR1’。可选的，在消息中携带AMF保存的UE-AMBR；
步骤705，基站向UE发送RRC连接重配置消息，携带上行PDU Session AMBR1’；
步骤706，UE向基站发送RCC连接重配置完成消息；
步骤707，基站向AMF发送修改PDU流应答消息；
步骤708，UE向基站发送直传消息；
步骤709，基站向AMF发送会话管理更新应答消息；
步骤710，步骤707后，AMF可向SMF发送PDU流更新应答；
步骤711，SMF向UPF发送更新用户面通道请求，将PDU session AMBR1’提供给UPF；
步骤712，基站再根据公式Min(UE-AMBR，Sum(PDU Session AMBR1’，PDU Session AMBR2))确定用于执行的UE-AMBR，并对UE的Non GBR业务进行带宽控制。
网络可以采用类似的流程更新PDU session AMBR2。
本申请实施例中，仅描述了UE建立一个PDU会话和同时建立2个PDU会话时，基站计算用于执行的UE-AMBR的流程。对于3个或3个以上PDU会话的流程也是类似的。
