Description

一种承载建立方法、分组数据网关、服务网关及系统 技术领域
本发明涉及通信领域，具体而言，涉及一种承载建立方法、分组数据网关、服务网关及系统。
背景技术
第三代合作伙伴计划(3GPP，3rd Generation Partnership Project)对下一代移动无线网络的项目叫系统架构演进(SAE，System Architecture Evolution)。SAE的架构如图1所示，其中包含了如下网元：
演进的无线接入网(E-RAN，Evolved RAN)：可以提供更高的上下行速率，更低的传输延迟和更加可靠的无线传输。E-RAN中包含的网元是基站(eNodeB，Evolved NodeB)，为终端的接入提供无线资源。
归属用户服务器(HSS，Home Subscriber Server)：永久存储用户签约数据。
移动管理实体(MME，Mobility Management Entity)：控制面功能实体，临时存储用户数据的服务器，负责管理和存储用户设备(UE，User Equipment)上下文(比如UE/用户标识，移动性管理状态，用户安全参数等)，为用户分配临时标识，当UE驻扎在该跟踪区域或者该网络是负责对该用户进行鉴权；处理MME和UE之间的所有非接入层消息；触发在SAE的寻呼；
服务GPRS支持节点(SGSN，Serving GPRS Support Node)，支持Gb或Iu接入的GPRS，临时存储用户数据的服务器，负责管理和存储GMM上下文和PDP上下文；处理SGSN和UE之间的所有非接入层消息；
服务网关(S-GW，Serving GW)：该网关是一个用户面实体，负责用 户面数据路由处理，终结处于空闲状态的UE的下行数据。管理和存储UE的SAE承载(bearer)上下文，比如IP承载业务参数和网络内部路由信息等。是3GPP系统内部用户面的锚点，一个用户在一个时刻只能有一个Serving GW；
分组数据网网关(PDN GW)：负责UE接入PDN的网关，分配用户IP地址，同时是3GPP和非3GPP接入系统的移动性锚点。用户在同一时刻能够接入多个PDN GW；
策略和合计费规则功能实体(PCRF，Policy and Charging Rule Functionality)：该功能实体主要根据业务信息和用户签约信息以及运营商的配置信息产生控制用户数据传递的服务质量(Qos，Quality of Service)规则以及计费规则。该功能实体也可以控制接入网中承载的建立和释放。用户附着到分组域演进网络，建立默认承载时，MME会把用户签约QoS携带给PDN GW/PCRF，签约QoS包括接入点汇聚最大比特率(APN-AMBR，Access Point Name-Aggregate Maximum Bit Rate)等参数。PDN GW/PCRF会决策使用的QoS，包括APN-AMBR等参数，APN-AMBR用于对相同APN下激活的所有non-GBR承载的速率限制，一般情况下，PDN GW/PCRF会直接使用签约的QoS。
专有承载建立时，PDN GW/PCRF根据业务流决策需要某APN的APN-AMBR增大或减小，然而按照目前3GPP标准，PDN GW无法将变化的APN-AMBR通知到无线接入网元和UE。另外MME因不知APN-AMBR变化，无法重新计算终端汇聚最大比特率(UE-AMBR，UE Aggregate Maximum Bit Rate)进而无法通知到无线接入网元变化的UE-AMBR，UE-AMBR用于对用户所有的non-GBR承载的速率限制，导致无线接入网元和UE无法执行变化后的QoS，可能影响用户感受，不便于运营商运营。
针对相关技术中的上述问题，目前尚未提出有效的解决方案。
