Description

服务质量能力协商方法、 服务质量参数转换方法及装置 技术领域
本发明涉及通信技术领域, 特别涉及一种服务质量能力协商方法、 服 务质量参数转换方法及装置。
背景技术
为了在未来 10年或者更长时间里, 第三代移动通信全球标准化组织 (3rd Generation Partnership Project, 3 GPP)的通用移动通信系统(Universal Mobile Telecommunication System, UMTS)都有很强的竞争力, 3GPP组织启 动了长期演进计划(Long Term Evolution, LTE)与系统框架演进(System Architecture Evolution, SAE)研究项目。
针对未来数据业务具有高速、 突发性的特征, 演进的分组系统 (Evolved Packet System, EPS)对服务质量 (Quality of Service, QoS)机制进行了诸多改进 与增强, 通过引入默认承载、 聚合资源调度等概念, 真正实现了用户的 "永 远在线" , 提高了业务的数据速率, 进而最终提升了用户体验。 同时, 针对 未来通用陆地接入网 (UMTS Terrestrial Radio Access Network, UTRAN)与演 进的通用陆地接入网 (Evolved-UTRAN, E-UTRAN) 之间的互操作场景, 设 计了 EPS的 QoS等级标识 (Qos Class Identifier, QCI)参数与 UMTS的 QoS参 数之间的合理映射。 在未来很长的一段时间内, 将会出现 UMTS系统和 SAE系统共存的现象, 在这种场景下, UMTS系统后续演进的一个主要方 向是和 SAE框架融合。 UMTS核心 QOS参数包含以下 14个:
流量类型(Traffic Class), 分配 /保留优先级(Allocation/Retention Priority ,ARP), 最大比特速率 (Maximum Bit Rate, MBR), 保证比特速率 (Guaranteed Bit Rate, GBR), 最大 SDU(Service Packet Unit)尺寸 (Maximum SDU Size), 源统计描述符 (Source Statistics Descriptor), 传送顺序 (Delivery Order) , SDU格式信息(SDU Format Information) , 误 SDU率 (SDU Error Ratio), 残余误比特率 (Residual Bit Error Ratio), 误 SDU的传送 (Delivery of Erromeous SDUs), 传输时延(Transfer Delay) , 流量处理优先级(Traffic Handling Priority) , 信令指示 (Signalling Indicator)。
SAE系统中, 承载级 QoS参数包括 QCI、 ARP、 GBR、 MBR和聚合最 大比特速率 (Aggregate Maximum Bit Rate, AMBR)。 其中, QCI与 AMBR两 个参数是 EPS系统新增加的, 其余参数则都沿用于现有的 UMTS系统, 本 领域将网络设备支持上述新增的 QoS参数的能力称为支持增强的 QoS能 力, 而将支持原有的 QoS参数的能力则称为支持传统的 QoS能力。 UMTS 后续网络演进 QoS增强主要是考虑向 SAE的 QoS模型靠拢, 在 UMTS模 型中逐步引入 AMBR和 QCI。 在引入过程中, 会出现 UMTS 网络中新旧 QoS参数共存的局面, 如果不能处理好一张网络中各种设备的 QoS能力不 同的问题将会影严重响网络性能。

图 3为本发明实施例的核心网设备和接入网设备之间进行 QoS能力协 商的流程图。 如图 3所示, 该方法包括:
步骤 S301、 核心网设备 SGSN向接入网设备 RNC发送无线接入承载分 配请求消息 (RAB Assignment Request) , 消息中携带具有增强的 QoS能力 的指示, 该指示可以是增强的 QoS参数包括 AMBR和 /或 QCI。
步骤 S302、 RNC接收到 RAB Assignment Request消息后进行解码, 如 果 RNC支持增强的 QoS 能力, 则在无线接入承载分配应答消息 (RAB Assignment Response) 中携带指示增强的 QoS能力的指示。 如果 RNC不支 持增强的 QoS能力, 则解码后不能识别 UE的增强 QoS能力, 在回复的 RAB Assignment Response消息中不携带增强的 QoS能力指示。
步骤 S303、 SGSN收到 RAB Assignment Response后, 根据消息中是否 携带有增强的 QoS能力指示判断 RNC是否支持增强的 QoS功能。 当 SGSN 和 RNC都支持增强的 QoS能力时, SGSN和 RNC之间采用增强的 QoS参 数进行业务交互, 否则采用传统的 QoS参数进行业务交互。 实施例 2: 本实施例提供一种 QoS参数转换的方法。 当终端设备 10不支持增强的
QoS能力, 而核心网设备 20支持增强的 QoS能力时, 本实施例的核心网设 备 20还可以将终端设备 10发送的消息中所携带的传统的 QoS参数转化为 增强的 QoS参数, 或者将由核心网发往终端设备 10的消息中携带的增强的 QoS参数转化为传统的 QoS参数。
终端设备和核心网设备经过实施例 1和 2的 QoS能力协商后可能会出 现四种结果: (1)如果 UE支持增强的 QoS能力, CN (Core Network, 核心 网) 也支持增强的 QoS能力, 则 UE利用增强的 QoS进行业务的请求; (2) 如果 UE支持增强的 QoS能力, CN不支持增强的 QoS能力, 则 UE利用未 增强的 QoS进行业务的请求; (3)如果 UE不支持 QoS增强的能力, CN也 不支持增强的 QoS能力,则 UE和 CN都采用传统的 QoS能力进行业务的 QoS交互; (4)如果 UE不支持 QoS增强的能力, CN支持增强的 QoS能 力, 则 UE和 CN都采用传统的 QoS能力进行业务的 QOS交互; 如果 RNC 支持增强的 QoS能力, SGSN将传统的 QoS能力映射到基于 QCI的增强的 QoS能力并传递给 RNC; 如果 RNC不支持增强的 QoS能力, 则沿用传统 的 QOS分配过程。
可选地, 本发明实施例的核心网设备为服务 GPRS支持节点 SGSN, 接 入网设备为无线网络控制器 (Radio Network Controller, RNC ) , 增强的 QoS参数可以包括: QCI和 /或 AMBR。 对于第 4种可能的结果, 本发明实 施例的核心网设备 20还会对 QoS参数进行转换。
图 4为本实施例进行 QoS参数转换的方法流程图之一; 如图 4所示, 该方法包括:
步骤 S401、 接收终端设备发送的包含传统服务质量参数的消息; 步骤 S402、 当核心网设备支持所述增强的服务质量能力时, 将所述终 端发送的消息中携带的传统服务质量参数转换为增强的服务质量参数;
步骤 S403、 发送包含转换为增强的服务质量参数的消息给核心网。 图 5为本实施例进行 QoS参数转换的方法流程图之二; 如图 5所示, 该方法包括:
步骤 S501、 接收核心网发送的包含增强的服务质量参数的消息; 步骤 S502、 当所述终端不支持所述增强的服务质量能力时, 将所述核 心网发送的消息中携带的增强的服务质量参数转换为传统服务质量参数; 步骤 S503、 发送包含转换为传统服务质量参数的消息给所述终端设 备。
需要说明的是, 实际的流程中可能既包含图 4的流程也包含图 5 的流 程。
图 6为本发明实施例进行 QoS转换的一种实际工作流程图。 如图 6所 步骤 S601、 UE发送激活 PDP(Packet Data Protocol,分组数据协议)上下 文请求 (Active PDP Context Request, APCR)到 SGSN, 该请求携带传统的 QoS参数。
步骤 S602、 SGSN收到 APCR后, 根据签约限制, 将 UE请求的传统的 QoS参数映射为基于 QCI的增强的 QoS参数, 该映射关系为协议中已经定 义的映射关系, 映射关系如表 4所示:
表 4
Figure imgf000012_0001
步骤 S603A、 SGSN将 RAB Assignment Request发送给 RNC, 该消息 携带有 QCI, AMBR, GBR, MBR等相关参数。
步骤 S603B、 RNC向 SGSN返回 RAB Assignment Response。
如果 RNC支持增强的 QoS能力,则 RNC将基于 QCI的增强的 QoS参 数映射为 RAB配置并返回配置成功的指示消息后进入步骤 S305; 如果 RNC不支持增强 QoS能力, 则不能识别该参数, 并将不支持该能 力的情况指示给 SGSN, SGSN重新利用传统的 UMTS QoS参数进行 RAB 分配过程。 该流程和目前 3GPP协议处理过程相同, 此处不再赘述。
步骤 S604、 SGSN将基于 QCI的增强的 QoS参数映射为 UMTS的 QoS 参数, 映射关系参见表 4。
步骤 S605、 SGSN 向 UE发送激活 PDP上下文接受消息 (Active PDP Context Accept, APCA), 该消息携带传统的 UMTS QoS参数。 实施例 3: 本发明实施例还提供一种核心网设备 20。 图 7为本发明实施例核心网 设备 20的功能框图。 如图 7所示, 本实施例的核心网设备 20包括: 第一接 收单元 201, 用于接收终端发送的包含增强的服务质量能力指示的接入请求 消息; 第一发送单元 202, 用于当所述核心网设备自身支持增强的服务质量 能力时, 返回包含增强的服务质量能力指示的接入应答消息。
