Description

数据的调度方法及装置
技术领域 本发明涉及通信领域, 具体而言, 涉及一种数据的调度方法及装置。 背景技术 随着数据业务的不断快速发展, HSPA (High Speed Packet Access, 高速包接入) 技术越来越普遍, 并且向多天线多载波的方向发展。 比如, 3GPP ( 3rd Generation partnership project,第三代移动通讯伙伴计划)的 R7版本引入了 MIMO (Multiple Input Multiple Output, 多输入多输出)技术, 使得 NodeB (节点 B)可以通过双天线从同一 个小区同时向 UE (User Equipment, 用户设备) 发送两个传输块; 随后, 3GPP的 R8 版本引入了 DC-HSDPA (Dual Cell HSDPA, 双小区 HSDPA) 技术, 使得 NodeB可以 同时从两个相邻载波上的服务小区发送 HSDPA (High Speed Downlink Packet Access, 高速下行包接入)数据块给 UE。这两个技术的引入,很大程度上提高用户的峰值速率。 当 UE处于两个同频小区边缘并执行软切换或者更软切换时,往往服务 HS-DSCH (High Speed Downlink Shared Channel, 高速下行共享信道)小区的空口能力受限, 而 激活集内的非服务 HS-DSCH小区还有可用资源, 如果能同时从非服务小区也发数据 给 UE, 将会大大提高用户感受, 从而也提高小区的数据吞吐量。 因此, 3GPP的 R11 版本开始讨论 HSDPA的多流技术。 针对上述的 HSDPA多点传输技术, 3GPP协议规 定在 MAC ( Medium Access Control, 媒体接入控制) 层引入多个 HARQ ( Hybrid Automatic Repeat Request,混和自动重复请求)实体,使得每个 TTK Transmission Timing Interval, 传输间隔)可以同时发送多个 HS-DSCH传输块, 从而大幅度提高空口速率。 对于数据量不大的数据, 通常不需要多点传输也能够快速地完成传输, 例如, 对 于非常关键的 RRC (Radio Resource Control, 无线资源控制)信令等, 由于其数据量不 大, 通常不需要多点传输也能快速准确地传完。然而, 随着无线信道快速衰落, HARQ 快速重传也不能完全保证高质量和高效率的数据传输,进而导致关键数据(例如, RRC 信令数据) 的发送延时和失败甚至掉话, 从而降低数据业务的用户体验。 综上所述, 在相关技术中存在数据传输准确性不高的问题, 针对如何提高数据传 输的确定性的问题, 目前尚未提出有效的解决方案。 发明内容 本发明实施例提供了一种数据的调度方案, 以至少解决上述问题。 根据本发明实施例的一个方面, 提供了一种数据调度的指示方法, 包括: 无线网 络控制器向基站发送拷贝发送指示, 其中, 所述拷贝发送指示用于指示是否通过多个 HARQ实体拷贝发送数据。 优选地, 所述拷贝发送指示所指示的信息还包括以下至少之一: 拷贝发送所述数 据的优先级队列;用于拷贝发送所述数据的 HARQ实体;拷贝发送的所述数据的类型;

2) 基站根据基站的预设策略确定通过多个 HARQ实体拷贝发送数据; 3 ) 基站根据拷贝 发送指示和基站的预设策略确定通过多个 HARQ实体拷贝发送数据。下面分别对上述 几种方式进行描述。 在本发明实施例的一个实施方式中, 基站可以根据拷贝发送指示确定通过多个 HARQ实体拷贝发送数据。 优选地, 基站可以获取拷贝发送指示, 并根据拷贝发送指 示判断是否通过多个所述 HARQ实体拷贝发送数据,如果是,基站确定通过多个 HARQ 实体拷贝发送数据。优选地基站可以从无线网络控制器发送的 NBAP信令和 /或携带上 述数据的数据帧中获取拷贝发送指示。 在实际应用中, 基站可以根据无线网络控制器发送的拷贝发送指示, 配置是否通 过多个所述 HARQ实体拷贝发送数据。 基站配置完成后, 基站在调度数据时, 可以根 据拷贝发送指示所指示的信息确定如何调度数据。 或者, 在携带数据的数据帧中获取 拷贝发送指示, 该拷贝发送指示可以指示该数据帧中数据是否需要拷贝发送。 在携带 数据的数据帧中未携带拷贝发送指示时, 根据配置的拷贝发送指示判断是否通过多个 HARQ发送数据。 在本发明实施例的一个实施方式中, 拷贝发送指示所指示的信息还可以包括但不 限于以下至少之一: 拷贝发送数据的优先级队列; 用于拷贝发送数据的 HARQ实体; 拷贝发送的数据的类型。 在实际应用中, 基站对于拷贝发送指示所指示的优先级队列 的数据拷贝发送; 或者, 基站对于拷贝发送指示所指示的拷贝发送的数据的类型进行 拷贝发送, 例如, 基站拷贝发送控制数据和 /或业务数据。 在本发明实施例的一个实施方式中, 在拷贝发送指示所指示的信息包括拷贝发送 数据的优先级队列时,基站根据拷贝发送指示判断是否通过多个 HARQ实体拷贝发送 数据时, 可以确定该数据所属的优先级队列, 并判断该数据所属的优先级队列是否为 拷贝发送数据的优先级队列,如果是,确定通过多个 HARQ实体拷贝发送数据。例如, 基站根据拷贝发送指示配置对 SPI ( Scheduling Priority index, 调度优先级索引) 为 15 的优先级队列的数据进行拷贝发送, 基站获取到数据后, 确定获取到的数据所属的优 先级队列的 SPI为 15, 则将该数据放入 SPI为 15的优先级队列, 基站对于 SPI为 15 的优先级队列中的数据进行拷贝发送。 优选地, 基站确定数据所属的优先级队列时, 可以根据发送该数据的数据帧携带 的优先级队列指示, 确定该数据所属的优先级队列, 其中, 优先级队列指示用于指示 数据所属的优先级队列。 在本发明实施例的另一个实施方式中, 在拷贝发送指示所指示的信息包括拷贝发 送的数据的类型时,基站根据拷贝发送指示判断是否通过多个 HARQ实体拷贝发送数 据时, 可以判断该数据的类型是否为拷贝发送的数据的类型, 如果是, 确定通过多个 HARQ实体拷贝发送该数据。 例如, 基站根据拷贝发送指示配置拷贝发送的数据为信 令数据, 基站获取数据后, 判断该数据是否为信令数据, 如果是, 则通过多个 HARQ 实体发送该数据。 在本发明实施例中, 拷贝发送的数据的类型包括: 信令数据和 /或业务数据。 优选 地, 可以指示基站对信令数据进行拷贝发送, 以避免信令数据传输不准确而导致通信 失败; 还可以指示对服务质量要求较高的数据进行拷贝发送,提高数据传输的成功率, 以保证数据业务的用户体验。 在本发明实施例的一个实施方式中, 基站可以通过拷贝发送指示所指定的 HARQ 实体和 /或基站确定的 HARQ实体拷贝发送数据。 优选地, 基站 MAC-ehs实体可以根 据内部实现算法动态选择 HARQ实体, 基站可以通过基站动态确定的 HARQ实体拷 贝发送数据。 在本发明实施例的一个实施方式中, 基站可以通过多个 HARQ实体在同一个 ΤΉ 或预定间隔的 ΤΉ中拷贝发送数据。优选地,预定间隔的 TTI的间隔时间不超过 HARQ 的 RTT范围, HARQ的 RTT是指 MAC-ehs实体通过 HARQ实体发送数据到收到对端 HARQ实体确认的时间差。 在本发明实施例的一个实施方式中, 基站还可以与无线网络控制器协商数据的类 型与优先级队列的对应关系。 例如, 协商将业务数据放置在 SPI为 11、 12等优先级队 列中调度, 将信令数据放置在 SPI为 9、 14等优先级队列中调度。基站在调度数据时, 根据数据的类型与优先级队列的对应关系, 将数据放置到相应的优先级队列。 在本发明实施例的另一种实施方式中, 基站可以根据基站的预设策略确定通过多 个 HARQ 实体拷贝发送数据。 优选地, 基站可以判断当前缓存的数据量和 /或当前的 空口资源是否满足预设条件, 如果是, 确定通过多个 HARQ 实体拷贝发送数据; 和 / 或, 基站可以判断数据所属的优先级队列是否为预设的优先级队列, 如果是, 确定通 过多个 HARQ实体拷贝发送数据。 在实际应用中, 基站可以预先设置对于优先级较高的优先级队列中的数据拷贝发 送, 例如, 基站确定数据所属的优先级队列的优先级高于预设阈值时, 确定通过多个 HARQ实体拷贝发送数据。 进一步的, 基站确定数据所属的优先级队列的优先级高于 预设阈值时, 还可以判断当前缓存的数据量和 /或当前的空口资源是否满足预设条件, 如果是, 确定通过多个 HARQ实体拷贝发送数据。 在本发明实施例的又一种实施方式中, 基站可以根据拷贝发送指示和基站的预设 策略共同确定通过多个 HARQ实体拷贝发送数据。例如, 在基站根据拷贝发送指示确 定通过多个 HARQ 实体拷贝发送数据时, 还可以判断当前缓存的数据量和 /或当前的 空口资源是否满足预设条件, 如果是, 则确定通过多个 HARQ实体拷贝发送数据。 例 如, 在基站缓存了大量需要发送的数据和 /或当前空口资源紧缺的情况下, 可以不对拷 贝发送指示所指示的数据进行拷贝发送。在实际应用中,可以根据实际需要进行设置, 以平衡下行容量和数据传输准确性。 实施例三 根据本发明实施例,提供了一种数据的调度方法,利用上述多点传输技术,对 RRC 信令等关键数据进行拷贝重复发送, 从而通过牺牲一些下行容量而提高关键数据传输 的准确性。 在本发明实施例中, 基于 HSDPA多点传输技术, MAC-ehs (MAC enhanced high speed, MAC 增强高速) 实体在进行数据调度的时候, 对关键数据可以从多个配置且 激活的 HARQ实体准同时地调度发送给用户。 图 8是根据本发明实施例三的数据的调度方法的流程图, 如图 8所示, 该方法主 要包括步骤 S802至步骤 S812。 步骤 S802, RNC (Radio Network Controller, 无线网络控制器)通过 NBAP (Node B Application Part, 节点 B应用部分) 信令通知 NodeB (节点 B) 中的 MAC-ehs实体 开启或者关闭拷贝发送功能。 优选地, RNC可以通过 NBAP信令静态指示哪些 HARQ实体可以参与拷贝发送;

NodeB, 其中, HS-DSCH数据帧携带该用户数据所属各个优先级队列的优先级指示。 优选地, 用户数据包括信令数据和业务数据; 进一步地, RNC还可以通过 HS-DSCH数据帧携带拷贝发送指示, 通知 NodeB该 HS-DSCH数据帧承载的数据是否需要拷贝发送。 步骤 S806, NodeB的 MAC-ehs实体接收用户数据并放入相应的优先级队列。 步骤 S808, MAC-ehs实体对上述优先级队列的数据进行调度, 并判断上述用户数 据是否需要拷贝发送。 优选地, MAC-ehs实体可以根据 NBAP信令指示判断上述优先级队列的数据是否 需要拷贝发送。进一步地, MAC-ehs实体还可以根据 NBAP信令指示只能针对信令数 据进行拷贝发送或者针对信令数据和业务数据都可以进行拷贝发送。 优选地, MAC-ehs实体还可以根据上述 HS-DSCH数据帧携带的拷贝发送指示判 断是否可以进行拷贝发送。 优选地, MAC-ehs实体还可以在满足缓存数据量比较小和 /或空口资源允许的条件 下对上述优先级队列的数据进行拷贝发送。 步骤 S810, MAC-ehs实体将需要拷贝发送的数据从相应的各 HARQ实体拷贝发 送给用户设备。 优选地, MAC-ehs实体可以在同一个 ΤΉ或者间隔若干个 ΤΉ后将需要拷贝发送 的数据从相应的各 HARQ实体拷贝发送给 UE; 进一步的, 间隔若干个 ΤΉ包括间隔 时间不超过 HARQ的 RTT范围, HARQ的 RTT是指 MAC-ehs实体通过 HARQ实体 发送数据到收到对端 HARQ实体确认的时间差。 优选地, 上述相应的各 HARQ实体可以是 NBAP信令指定的 HARQ实体, 也可 以是 MAC-ehs实体根据内部实现算法动态选择的 HARQ实体。 步骤 S812, UE从相应的各 HARQ实体正确接收数据块后, 经过解复用、 重排序 以及重组后, 投递给上层的 RLC (Radio Link Control, 无线链路控制) 实体, 由 RLC 实体对重复数据进行丢弃。 通过本发明实施例,采用对 RRC信令等关键数据进行拷贝发送, 从而很大程度上 提高了关键性数据传输的准确性, 并缩短数据传输时延, 提高了移动鲁棒性。 实施例四 根据本发明实施例, 提供了一种 MAC数据调度的优化方法, 该方法基于 HSDPA 多点传输技术。
RNC通过 HS-DSCH数据帧将用户数据发送给 NodeB, NodeB的 MAC-ehs实体 接收用户数据并放入相应的优先级队列, 并在每个 ΤΉ到达时对各个优先级队列的用 户数据进行调度, 如果判断用户数据需要拷贝发送, 则将该用户数据从相应各 HARQ 实体拷贝重复发送给用户设备。 在本发明实施例中, 用户数据包括信令数据和业务数 据。信令数据包括通过 DCCH信道传输的数据; 业务数据包括通过 DTCH信道传输的 数据。 RNC可以通过 NBAP信令通知 NodeB只对信令数据进行拷贝发送, 或者对信令 数据和业务数据都可以进行拷贝发送, 或者对信令数据和业务数据都不可以进行拷贝 发送。在本发明实施例的一个实施方式中, RNC可以通过 NBAP信令指示相应各个优 先级队列的数据是否允许拷贝发送, 如表 1和表 2所示, MAC复制允许指示 (MAC Duplication Allowed Indicator) 为"允许" (Allowed), 则相应的优先级队列的数据允许 拷贝发送; MAC Duplication Allowed Indicator为"不允许 "(Not Allowed), 则相应的优 先级队列的数据不允许拷贝发送。 表 1, HS-DSCH MAC-d流信息 (HS-DSCH MAC-d Flows Information) 表

UE从相应的各 HARQ实体正确接收数据块后,经过重排序,并投递给上层的 RLC 实体, 因此, RLC实体会收到多份同样的数据。 对于 RLC数据包, 由于后面收到的 是相同序列号的 RLC数据 PDU, 则会被认为出窗, 从而被 RLC实体丢弃; 对于 RLC 状态包, 如果后面收到的 RLC状态 PDU包含错误的 RLC序列号, 则会被 RLC实体 忽略。 在本发明实施例的再一个实施方式中, RNC还可以通过 HS-DSCH数据帧携带拷 贝发送指示,通知 NodeB该 HS-DSCH数据帧承载的数据是否需要拷贝发送, HS-DSCH 的数据帧结构如图 9所示。 在发明实施例的方法适用于 NodeB内配置 2个或者 2个以上 HARQ实体的场景, 包括 LTE (Long Term Evolution, 长期演进) 通信系统等。 图 10是根据本发明实施例四的数据的调度方法的流程图, 如图 10所示, 该方法 主要包括步骤 S1002至步骤 S1016。 步骤 S1002, UE向网络侧发起信令承载和 /或业务承载请求。 步骤 S1004, RNC 向 NodeB 发送无线链路建立请求 /无线链路重配请求, 通知 NodeB建立 HARQ实体, 建立相应的优先级队列。 步骤 S1006, RNC向 UE发送信令承载和 /或业务承载建立响应。 步骤 S1008, RNC向 NodeB发送信令数据和 /或业务数据。 步骤 S1010, NodeB判断是否需要拷贝发送, 如果是, 执行步骤 S1012, 如果否, 结束。 步骤 S1012, NodeB判断是否动态选择 HARQ实体进行拷贝发送, 如果否, 执行 步骤 S1014, 如果是, 执行步骤 S1016。 步骤 S1014, NodeB按照 RNC指定的 HARQ实体进行拷贝发送, 结束。 步骤 S 1016, NodeB动态选择 HARQ实体进行拷贝发送, 结束。 下面结合具体实例对本发明实施例的上述方法进行描述。 实例 1 在本实例中, 以 RRC连接过程且由 NodeB动态选择 HARQ实体进行拷贝发送为 例, 对本发明实施例的上述方法进行描述。 在实例 1中, 数据的调度方法可以包括步骤 1至步骤 8。 步骤 1, UE向网络侧发起 RRC连接请求。 步骤 2, RNC向 NodeB发送无线链路建立消息, 通知 NodeB建立 4个 HARQ实 体, 同时通知 NodeB 建立承载信令数据的优先级队列, 且设置其优先级指示 SPI (Scheduling Priority index, 调度优先级索引)为 15; 并指示该优先级队列的数据允许 拷贝发送, 即 MAC Duplication Allowed Indicator为 Allowed。 步骤 3, NodeB中 MAC-ehs实体相应建立 4个 HARQ实体, 同时建立 SPI为 15 的优先级队列, 并向 RNC响应无线链路建立成功。 步骤 4, RNC向 UE发送 RRC建立消息, UE回应 RRC建立完成消息。 步骤 5, RNC构造给 UE的测控消息, 并通过 HS-DSCH数据帧带给 NodeB, 其 中携带优先级指示 CmCH-PI (Common Transport Channel Priority Indicator, 公共传输 信道优先级指示) 为 15。 步骤 6, NodeB的 MAC-ehs实体将上述测控消息的数据放入优先级指示为 15的 优先级队列。 步骤 7, NodeB的 MAC-ehs实体对优先级指示为 15的优先级队列进行调度, 根 据 RNC指示, 该优先级队列的数据允许拷贝发送, 而且数据量不大, 因此, MAC-ehs 实体自主动态选择两个所归属服务小区空口资源比较空闲的 HARQ实体将上述测控消 息的数据双份重复地发送给 UE。 步骤 8, UE相应的两个 HARQ实体收到后, 经过排序重组后投递给 RLC, RLC 实体将重复的 RLC数据包丢弃, 并将有效的数据重组后提交给 RRC层。 实例 2 在本实例中, 以 PDP (Packet Data Protocol, 包数据协议)激活过程为例, 对本发 明实施例的上述方法进行描述。 假设 NodeB建立了 4个 HARQ实体, 由 RNC静态指 定参与拷贝发送的 HARQ实体;而且 RNC还指示 NodeB对业务数据也允许拷贝发送。 在实例 2中, 数据的调度方法可以包括步骤 1至步骤 10。 步骤 1, UE向网络侧发起 PDP请求,核心网向 RNC发起 RAB( Radio Access Bearer, 无线接入承载) 指派请求, 其中业务类型为交互类。 步骤 2, RNC向 NodeB发送无线链路重配消息, 通知 NodeB建立承载业务数据 的优先级队列, 且设置其优先级指示 SPI为 9; 同时指示该优先级队列的数据允许拷 贝发送,即 MAC Duplication Allowed Indicator为 Allowed,并指示 HS-DSCH Information To Modify和 HS-DSCH FDD Secondary Serving Information To Modify指示 NodeB通过 服务 HS-DSCH小区和第 1辅服务 HS-DSCH小区的 HARQ实体进行拷贝发送,即 MAC Duplication membership Status设置为 member。 步骤 3, NodeB中 MAC-ehs实体建立优先级指示为 9的优先级队列, 并向 RNC 响应无线链路重配完成消息。 步骤 4, RNC向 UE发送 RB (Radio Bearer, 无线承载) 建立消息, UE回应 RB 建立完成消息。 步骤 5, RNC向核心网发送 RAB建立完成消息, 核心网向 UE响应 PDP激活接 受消息。 步骤 6, UE向 PDN (Packet Data Network,报文数据网络)发起 FTP ( File Transfer Protocol, 文件传输协议) 下载请求, PDN向 RNC发送 FTP下载响应。 步骤 7, RNC通过 HS-DSCH数据帧将 FTP下载响应带给 NodeB, 其中携带优先 级指示 CmCH-PI为 9。 步骤 8, NodeB的 MAC-ehs实体将上述 FTP下载响应的数据放入优先级指示为 9 的优先级队列。 步骤 9, NodeB的 MAC-ehs实体对优先级指示为 9的优先级队列进行调度, 由于 数据量不大,而且根据 RNC指示,该优先级队列的数据允许拷贝发送。因此, MAC-ehs 实体通过 RNC指定的 HARQ实体将上述 FTP下载响应的数据发送给 UE。 步骤 10, UE相应的两个 HARQ实体收到后, 经过排序重组后投递给 RLC, RLC 将重复的数据丢弃, 并将有效数据重组后投递给应用层。 实例 3 在本实例中, 以小区更新过程为例, 对本发明实施例的上述方法进行描述。 在实例 3中, 数据的调度方法可以包括步骤 1至步骤 10。 步骤 1, UE向网络侧发起小区更新请求。 步骤 2, RNC向 NodeB发送无线链路建立消息, 通知 NodeB建立 2个 HARQ实 体; 并通知 NodeB建立承载 RRC信令数据的优先级队列, 且设置其优先级指示 SPI 为 15; 同时通知 NodeB建立承载业务数据的优先级队列, 且设置其优先级指示 SPI 为 9。 步骤 3, NodeB相应建立了两个 HARQ实体, 并分别建立优先级指示为 15和优 先级指示为 9的优先级队列, 并向 RNC回应无线链路建立完成消息。 步骤 4, RNC向 UE发送小区更新证实消息, 通知 UE重建承载信令数据的 RLC 实体, 而且不需要重建承载业务数据的 RLC实体, UE回应小区更新证实完成消息。 步骤 5, RNC构造给 UE的测控消息, 并通过 HS-DSCH数据帧带给 NodeB, 其 中携带优先级指示 CmCH-PI为 15, 并且携带拷贝发送指示 Dup Ind为 1。 步骤 6, RNC还可以通过 HS-DSCH数据帧将承载业务数据的 RLC实体的下行状 态包带给 NodeB,其中携带优先级指示 CmCH-PI为 9;并且携带拷贝发送指示 bCopylnd 为 1。 步骤 7, NodeB将上述测控消息的数据放入优先级指示为 15的优先级队列, 并将 上述 RLC状态包放入优先级指示为 9的优先级队列。 步骤 8, NodeB的 MAC-ehs实体对优先级指示为 15的优先级队列进行调度, 由 于 bCopylnd为 1, 说明需要拷贝发送, 因此, MAC-ehs实体选择两个归属小区比较空 闲的 HARQ实体将上述测控消息的数据发送给 UE。 步骤 9, NodeB的 MAC-ehs实体对优先级指示为 9的优先级队列进行调度, 由于 bCopylnd为 1, 说明需要拷贝发送, 因此, MAC-ehs实体选择两个归属小区比较空闲 的 HARQ实体将上述测控消息的数据发送给 UE; 步骤 10, UE相应的两个 HARQ实体收到后, 经过排序重组后投递给 RLC, RLC 将重复的数据丢弃, 并将有效的数据进行重组。 对于测控消息, UE的 RLC实体提交 给 RRC层; 对于 RLC状态包, UE的 RLC实体更新相应的状态变量。 从以上的描述中, 可以看出, 本发明实施例实现了如下技术效果: 基站根据拷贝发送指示和 /或基站的预设策略确定通过多个 HARQ 实体拷贝发送 数据, 并通过多个 HARQ实体拷贝发送所述数据, 其中, 拷贝发送指示用于指示是否 通过多个 HARQ实体拷贝发送数据, 使得数据可以通过多个 HARQ实体重复发送, 提高了数据传输的准确性。尤其是对 RRC信令等关键数据进行拷贝发送, 从而很大程 度上提高了关键性数据传输的准确性, 并缩短数据传输时延, 提高了移动鲁棒性。 显然, 本领域的技术人员应该明白, 上述的本发明的各模块或各步骤可以用通用 的计算装置来实现, 它们可以集中在单个的计算装置上, 或者分布在多个计算装置所 组成的网络上, 可选地, 它们可以用计算装置可执行的程序代码来实现, 从而, 可以 将它们存储在存储装置中由计算装置来执行, 并且在某些情况下, 可以以不同于此处 的顺序执行所示出或描述的步骤, 或者将它们分别制作成各个集成电路模块, 或者将 它们中的多个模块或步骤制作成单个集成电路模块来实现。 这样, 本发明不限制于任 何特定的硬件和软件结合。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本领域的技 术人员来说, 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内, 所作的 任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之内。
