Description

HSDPA ( High Speed Downlink Packet Access, 高速下行分组接入系统,以 下简称 HSDPA ) 是 3GPP (第三代合作伙伴计划）在 R5协议中为了满足上 /下行 数据业务不对称的需求而提出的一种新技术> 它很好地解决了系统覆盖与容量 之间的矛盾， 大大提升了系统容量， 满足了用户的高速业务需求。 HSDPA 引 入了短的传输时间间隔（ 2ms：), 采用自适应调制编码（ Adaptive Modulation and Coding , 以下简称 AMC ) 和混合自动重传请求 （Hybrid Automatic Repeat Request, 以下简称 HARQ )作为链路自适应方法， 并将分组调度器从无线网络 控制器 （ Radio Network Controller, 以下简称 RNC )移到 Node B (基站）中， 从 而更便于接入空口无线环境。 Node B在进行快速分组调度和链路自适应时需要考虑 RNC通过 Iub口映 射的业务 QoS ( Quality of Service, 服务质量）参数， 如由无线接入承载（ Radio Access Bearer , 以下筒称 RAB ) 指派 QoS 参数 " Traffic class "、 " Allocation/Retention priority "、 " Traffic handling priority " 映射而来的 "Scheduling Priority Indicator" 调度优先级参数， 由 "Guaranteed bit rate " 映 射而来的 "MAC-hs Guaranteed Bit Rate"保 ϊ正比特速率参数，由 "Transfer delay" 映射而来的 "Discard Timer" 时延参数， 以及 "RLC Mode" 参数等。 Node B 按照上述 QoS参数以及其它策略进行调度， 即可基本满足分组业务对优先级、 保证速率以及时延的要求。 但对于 HSDPA所承载的分组业务， 一个非常重要的 QoS需求是丢包率： 对于交互类和背景类业务， 没有保证比特速率和时延的需求， 但对丢包率要求 的非常严格； 而对于分组流类业务， 有保证比特速率和时延的要求， 更有丢包 率的要求， 丟包率的要求甚至比传递时延还要严格。 在目前的协议中， 由于 RNC没有将丟包率相关的 RAB QoS参数 "SDU error ratio" 映射给 Node B, Node B在分组调度和链路自适应时或者不能很好地保证丟包率 （HARQ达到 最大重传次数后丟包率过高）， 或者减小了系统容量 （HARQ 达到最大重传次 数后丟包率过低， 重传次数过多或浪费了功率资源）。 另外无线链路控制层确 认模式（ Radio Link Control Acknowledged Mode,以下简称 RLC AM )中的 ARQ 是一种数据传输失败时就重传的选择性重传机制， 而 Node B 中的 HARQ将 ARQ和前向纠错编码相结合， 不但可以灵活地调整有效编码速率，还可以补偿 由于采用链路适配所带来的误码， 从而大大提高系统性能。 RLC AM ARQ和 HARQ如果能协调工作，共同分担业务的丟包率 QoS要求， 可更好地保证业务 的 QoS。 目前 4十对上述情况， 还没有发现已公开的专利。 发明内容 本发明所要解决的技术问题是提供一种高速下行分组接入系统服务质量 映射与保证方法，解决现有技术无线网絡控制器没有将丢包率相关的 QoS参数 映射给基站， 基站在分组调度和链路自适应时不能很好地保证丟包率的技术问 题。 为达到上述目的，本发明提供了一种高速下行分组接入系统服务质量映射 与保证方法， 其特点在于， 无线网络控制器根据核心网指派的无线接入承载 QoS参数以及无线链路控制层的模式的配置策略制定丟包率需求参数， 并向基 站映射所述丟包率需求参数， 由基站保证高速媒体接入控制层的丟包率不超过 所述丟包率需求参数。 上述的方法， 其特点在于， 所述无线接入承载 QoS参数指示了无线网络 侧数据包丢失或检测为错误的比例。 上述的方法， 其特点在于， 进一步包括如下步眯： 步驟一， 在用户接入时， 无线网络控制器首先检查核心网下发的无线接入 承载 QoS参数，根据无线资源管理策略，确定所采用的无线链路控制层的模式， 并且决定是否选择高速下行共享信道来处理业务请求， 是则执行步骤二， 否则 采用专用信道或公共信道处理所述业务请求并且结束流程； 步骤二，无线网络控制器为所述高速下行共享信道配置相关的功率资源和 码资源； 步骤三， 无线网络控制器根据所述无线接入承载 QoS参数映射出 QoS参 数信元； 步骤四， 无线网络控制器根据业务请求类型、 无线接入承载 QoS参数以 及所选择的无线链路控制层的模式进行映射以确定所述丢包率需求参数， 并配 置初始传输的的误块率； 步驟五， 无线网络控制器将所述 QoS参数信元和所述丢包率需求参数包 含在高速下行共享信道信息的信元的子信元中， 通过 Iub口的无线链路建立、 增加或重配过程配置给基站； 步骤六， 基站在分組调度和链路自适应时， 通过 QoS检测和控制手段确 保所述丢包率需求参数得到满足。 上述的方法， 其特点在于， 在所述步骤三中， 所述 QoS参数信元为调度 优先级参数。 上述的方法， 其特点在于， 在所述步驟三中， 如果业务类型为流类业务， 则所述 QoS参数信元为保证比特速率参数和时延参数。 上述的方法， 其特点在于， 在所述步骤四中， 如果业务类型为对时延敏感 的流类业务， 并且无线链路控制层的模式为非确认模式， 则将所述丟包率需求 参数映射为低于所述无线接入承载 QoS参数指示的数值，并且所述初始传输的 的误块率设置为 , j、于协议规定的上报信道质量指示时的误块率。 上述的方法， 其特点在于， 在所述步骤四中， 如果业务类型为对时延敏感 的流类业务， 并且无线链路控制层的模式为确认模式， 则将所述丟包率需求参 数映射为不超过所述无线接入承载 QoS参数指示的数值，并且所述初始传输的 的误块率设置为小于协议规定的上报信道质量指示时的误块率。 上述的方法， 其特点在于， 在所述步骤四中， 如果业务类型为对时延不敏 感的交互类或背景类业务， 并且无线链路控制层的模式为非确认模式， 则将所 述丢包率需求参数映射为略低于所述无线接入承载 QoS参数指示的数值，并且 所述初始传输的的误块率设置为大于协议规定的上报信道质量指示时的误块 率。 上述的方法， 其特点在于， 在所述步-骤四中， 如果业务类型为对时延不敏 感的交互类或背景类业务， 并且无线链路控制层的模式为确认模式， 则将所述 丟包率需求参数映射为高于所述无线接入承载 QoS参数指示的数值，并且所述 初始传输的的误块率设置为大于协议规定的上报信道质量指示时的误块率。 本发明的技术效果在于: 本发明所述的 HSDPA 系统 QoS映射和保证方法， 可根据 RAB指派的
QoS参数将业务的优先级、保证比特速率、 时延尤其是丢包率等 QoS需求参数 映射到 Node B, Node B在分组调度和链路自适应时对上述业务 QoS需求加 以考虑， 从而确保了业务的 QoS需求得到满足， 并可有效地提高系统容量。 附图说明 图 1是通用移动通信系统 QoS映射架构； 图 2是本发明的业务初始接入 HS-DSCH流程图； 图 3是本发明的 RAB 指派 QoS参数到 Node B QoS参数的映射流程图。 具体实施方式 下面结合附图对本发明所述技术方案的实施作进一步详细描述： 本发明主要是提供一种 HSDPA系统 QoS映射和保证机制， RNC根据核 心网 （ Core Network, 以下简称 CN )指派的 RAB QoS参数 "SDU error ratio" (服务数据单元差错率） 以及 RLC AM/UM配置策略， 给 Node B映射丟包率 需求参数 "Residual BLER for HARQ" ( HARQ残留误块率）， Node B负责保证 在 MAC-hs(高速媒体接入控制）层的丟包率不超过" Residual BLER for HARQ" 的情况下， 提高系统的容量并保证业务的其它 QoS需求得到满足。
RAB QoS参数 "SDU error ratio"指示了无线网络侧数据包丢失或检测为 错误的比例， 在 RLC层统计（若为 RLC AM, 则指达到 ARQ最大重传次数后 的丢包率）。 若采用无线链路控制层非确认模式 （ Radio Link Control Unacknowledged Mode, 以下简称 RLC UM ), "SDU error ratio" 参数主要影响 Node B侧达到 HARQ最大重传次数后的残留 BLER, 即 "Residual BLER for HARQ"的配置， 所配置的残留 BLER应略低于 "SDU error ratio"指示的数值； 若采用 RLC AM,则一方面影响 Node B侧的残留 BLER,即 "Residual BLER for HARQ" 的配置， 另一方面影响 RLC ARQ最大重传次数的配置， 若残留 BLER 配置得低一些， 则 RLC ARQ重传次数就可 、一些， 相反若残留 BLER配置得 较高，则 RLC ARQ重传次数就要较多，以保证 RLC层统计的丟包率低于 "SDU error ratio" 指示的数值。 由于 HARQ效率比较高， 一般而言， 残留 BLER应 该配置得¼^一些。 本发明所述的 HSDPA系统 QoS映射和保证方法步骤如下： 第一步： 当有流类、 背景类或者交互类的用户接入时， RNC首先检查 CN 下发的 RAB指派 QoS参数， 居无线资源管理 ( Radio Resource Management, 以下简称 RRM ) 策略， 决定是选择专用信道还是共享信道来处理业务请求， 并且决定是采用 RLC AM还是采用 RLC UM。 第二步：若选择高速下行共享信道（ High Speed Downlink Shared Channel, 以下简称 HS-DSCH ) 承载业务， 则 RNC需要为 HS-DSCH配置相关的功率资 源和码资源， 同时需要将 RAB指派 QoS参数映射给 Node B , 以供 Node B分 组调度和链路自适应时参考。 第三步： RNC 居 RAB指派 QoS参数" Traffic class"、 "Allocation/Retention priority"、 "Traffic handling priority" 映射 "Scheduling Priority Indicator" 调度 优先级参数。 若业务类型为流类业务， 则 ~据 "Guaranteed bit rate " QoS参数 映射 "MAC-hs Guaranteed Bit Rate" 保证比特速率参数， 并且根据 "Transfer delay" QoS参数映射 "Discard Timer" 时延参数。 第四步： RNC根据业务请求类型、 RAB QoS参数 "SDU error ratio" 以及 所选择的 RLC模式映射 "Residual BLER for HARQ" 参数， 并为 HARQ配置 适当的初始传输的 BLER, 以便既保证业务的时延和保证比特速率要求， 又保 证业务的丟包率要求。 本步錄又可包括以下子步骤：
1.若业务类型为时延敏感的流类业务且采用 RLC UM , 则映射到 Node B 的 "Residual BLER for HARQ" 参数略低于 "SDU error ratio" 指示的数值， 且 可为 Node B 的 HARQ配置比较低的初始传输的 BLER (小于协议规定的上报 CQI (质量测量指示）时 10%的 BLER ), 以在分组调度和链路自适应时既保证 业务的丟包率需求得到满足， 又保证流类业务的时延得到满足。
2.若业务类型为时延敏感的流类业务但采用 RLC AM,考虑到 RLC AM虽 具有 ARQ重传但 ARQ重传时延比较大， 仅可用于在 HARQ传输异常如非确 认 NACK误判为确认 ACK时的 "补漏"处理， 因此映射到 Node B的 "Residual BLER for HARQ"参数应不超过 "SDU error ratio"指示的数值， 且可为 Node B 的 HARQ配置比较低的初始传输的 BLER (小于协议规定的上报 CQI时 10% 的 BLER )o
3,若业务类型为对时延不敏感的交互类 /背景类业务但采用 RLC UM, 同 样要使得映射到 Node B的 "Residual BLER for HARQ"参数略低于 "SDU error ratio" 指示的数值， 但可为 Node B的 HARQ配置比较高的初始传输的 BLER
(大于协议规定的上 CQI时 10%的 BLER ), 以充分利用 HARQ重传带来的 增益。
4.若业务类型为对时延不敏感的交互类 /背景类业务但采用 RLC AM, 考 虑到交互类 /背景类业务没有时延需求且 RLC AM具有 ARQ重传， 可将 "SDU error ratio"指示的丟包率分担在 ARQ和 HARQ上， 但考虑到 HARQ的效率比 ARQ高，映射到 Node B的 "Residual BLER for HARQ"参数不要高出 "SDU error ratio" 指示的数值太多， 且可为 Node B 的 HARQ 配置比较高的初始传输的 BLER (大于协议规定的上报 CQI时 10%的 BLER )， 以充分利用 HARQ重传 带来的增益。 第五步： RNC将由 RAB指派 QoS参数映射得到的 "Scheduling Priority Indicator"、 "MAC-hs Guaranteed Bit Rate"、 "Discard Timer"和 "Residual BLER for HARQ" 等 QoS 参数信元包含在 "HS-DSCH Information" 信元的子信元 "HS-DSCH MAC-d Flows Information" 中， 通过 Iub口的无线链路建立、 增加 或重配过程配置给 Node B。 第六步： Node B在分组调度和链路自适应时考虑由 RNC映射而来的上述 QoS参数， 并通过 QoS检测和控制手段确保上述 QoS需求得到满足。 图 1是通用移动通信系统 ( Universal Mobile Telecommunication System , 以下简称 UMTS ) QoS映射架构。 端到端的 QoS可映射为 UMTS QoS、 外部 网络 QoS和 TE/MT本地f 载 QoS。UMTS QoS可映射为 RAB QoS和 CN QoS , 其中 RAB QoS可映射为无线 载 ( Radio Bearer, 以下简称 RB ) QoS和无线 接入网络（ Radio Access Network , 以下简称 RAN )接入 载 QoS。 RB QoS又 可进一步映射为物理无线 载 QoS。 图 2是业务初始接入 HS-DSCH (高速下行共享信道）流程图。 当有流类、 交互类或者背景类的业务请求接入时 （步骤 201 ), RNC首先检查 CN下发的 RAB指派 QoS参数 (步骤 202 ), 接下来需要根据 RRM策略， 进行业务初始 接入的信道选择，并选择 RLC模式（是采用 RLC AM还是 RLC UM承载业务 ) (步骤 203 ), 并根据业务初始接入选择的信道分别进行处理（步驟 204 )。 若 业务初始接入选择的不是 HS-DSCH信道， 则转向专用信道或公共信道处理流 程进行处理 （步骤 207 )。 若业务初始接入选择的是 HS-DSCH信道， 贝' J RNC 需要为 HS-DSCH配置相关的功率资源和码资源（步骤 205 ), 同时需要将 RAB 指派 QoS参数映射给 Node B , 以供 Node B分组调度和链路自适应时参考（步 骤 206 )。 图 3是 RAB 指派 QoS参数到 Node B QoS参数的映射流程图。 RNC需 要首先检查 RAB指派的 QoS参数（步骤 301 ), 居 RABQoS参数 "Traffic class"、 "Allocation/Retention priority"、 "Traffic handling priority" 等为 Node B 映射 "Scheduling Priority Indicator"调度优先级参数 (步骤 302 )。 接下来 RNC 需要检查业务类型及所选择的 RLC模式，以在映射丢包率参数时区别处理（步 骤 303 )0 若业务类型为流类且采用 RLC UM承载 （步骤 304 ), 则需要首先根 据 RAB指派的 "Guaranteed bit rate " QoS参数映射 "MAC-hs Guaranteed Bit Rate" 保证比特速率参数（步驟 305 ), 并且根据 "Transfer delay" QoS参数映 射 "Discard Timer" 时延参数（步骤 306 ), 接下来考虑到业务的丟包率和时延 要求， 映射到 Node B的 "Residual BLER for HARQ" 参数略低于 "SDU error ratio"指示的数值（步骤 307 ), 且可为 Node B 的 HARQ配置比较低的初始传 输的 BLER (小于协议规定的上报 CQI时 10%的 BLER ) (步骤 308 ); 若业务 类型为流类且采用 RLC AM承载（步驟 309 ), 同样需要首先根据 RAB指派的 "Guaranteed bit rate " QoS参数映射 "MAC-hs Guaranteed Bit Rate"保证比特 速率参数 (步骤 310 ),并且 居 "Transfer delay" QoS参数映射 "Discard Timer" 时延参数 (步骤 3 1 1 ), 考虑到 RLC AM虽具有 ARQ重传但 ARQ重传时延比 较大，仅可用于在 HARQ传输异常如非确认 NACK误判为确认 ACK时的 "补 漏" 处理， 因此映射到 Node B的 "Residual BLER for HARQ" 参数应不超过 "SDU error ratio" 指示的数值 (步 3 12 ), 且可为 Node B 的 HARQ配置比 较低的初始传输的 BLER (小于协议规定的上报 CQI时 10%的 BLER ) (步骤 313 ); 若业务类型为交互类 /背景类且采用 RLC UM 载（步骤 314 ), 由于没 有时延和保证比特速率的要求， 不需要映射这两个参数， 同样要使得映射到 Node B的 "Residual BLER for HARQ" 参数略低于 "SDU error ratio" 指示的 数值（步骤 315 ),但可为 Node B的 HARQ配置比较高的初始传输的 BLER(大 于协议规定的上报 CQI时 10%的 BLER ), 以充分利用 HARQ重传带来的增益
(步骤 316 ); 若业务类型为交互类 /背景类且采用 RLC AM承载 （步骤 317 ), 同样不需要映射时延和保证比特速率参数，考虑到交互类 /背景类业务没有时延 需求且 RLC AM具有 ARQ重传， 可将 "SDU error ratio" 指示的丢包率分担在 A Q和 HARQ上， 但考虑到 HARQ的效率比 ARQ 高， 映射到 Node B的
"Residual BLER for HARQ" 参数高于但不要高出 "SDU error ratio" 指示的数 值太多 （步骤 318 ), 且可为 Node B的 HARQ配置比较高的初始传输的 BLER
(大于协议规定的上报 CQI时 10%的 BLER ), 以充分利用 HARQ重传带来的 增益 （步骤 319 )。 RNC将由 RAB指派 QoS参数映射得到的上述 QoS参数信 元包含在 "HS-DSCH Information" 信元的子信元 "HS-DSCH MAC-d Flows Information" 中， 通过 Iub口的无线链路建立、 增加或重配过程配置给 Node B
(步骤 320 )。 Node B在分组调度和链路自适应时考虑由 RNC映射而来的上述 QoS参数，并通过 QoS检测和控制手段确保上述 QoS需求得到满足（步骤 321 )。 由上可知，本发明所述的 HSDPA系统 QoS映射和保 iiL机制，其基本思想 是 RNC根据 CN指派的 RAB QoS参数 "SDU error ratio" 以及 RLC AM/UM 配置策略， 将丟包率需求参数 "Residual BLER for HARQ" 映射给 Node B , Node B 负责保证在 MAC-hs层达到 HARQ最大重传次数后的丟包率不超过 "Residual BLER for HARQ" 的情况下，提高系统的容量并同时保证业务的其 它 QoS需求也得到满足。 以上所述仅为本发明的较佳实施例，并非用来限定本发明的实施范围； 凡 是依本发明所作的等效变化与修改， 都被本发明的专利范围所涵盖。
