Description

一种轮询方法、 系统及设备 技术领域
本发明涉及无线通信技术领域, 尤其涉及一种轮询方法、 系统及 设备。 背景技术
EDGE ( Enhanced Data rates for GSM Evolution, GSM演进增强 数据速率 ) 是一种基于 GSM ( Global System for Mobile communications, 全球移动通信系统) /GPRS ( General PACKet Radio Service, 通用分组无线业务) 网络的数据增强型移动通信技术, 通 常又称为 2.75G技术。 该技术主要在于能够使用宽带服务, 能够让使 用 800、 900、 1800、 1900MHz频段的网络提供第三代移动通信网络 的■ ^分功能,与 UMTS ( Universal Mobile Telecommunications System, 通用移动通信系统)共用核心网,通过引入 Iu接口,演进 GSM/EDGE 无线接入网成为 GERAN ( GSM EDGE Radio Access Network, GSM EDGE无线接入网)。
EDGE中高层每一个 LLC ( Logic Link Control, 逻辑链路控制) 帧由一系列 RLC ( Radio Link Control, 无线链路控制)块组成, 如图 1所示。 每 RLC数据块有相应的 BSN ( Block Sequence Number, 块 序号), 并按照 BSN的次序进行传输。 无线块是无线资源分配和无线 传输的基本单位, 每个无线块由 4个时隙组成, 且分别位于 4个连续 的 TDMA ( Time Division Multiple Access, 时分多址)帧。 RLC数据 块的传输均由无线块承载, 因编码方式的不同, 1个无线块最多可以 承载 2个 RLC数据块。 为了优化分组交换模式下的数据传输, RLC 数据块传输在 RLC/MAC ( Media Access Control, 媒体接入控制)确 认模式下受 ARQ ( Automatic Repeat reQuest , 自动重复请求)机制控 制, 通过轮询让移动终端 (例如 MS )报告相关下行链路状况及成功 接收的 RLC数据块的信息。轮询机制仅适用于下行数据传输,由 PCU ( Packet Control Unit, 分组控制单元)控制下发轮询请求, 作为发送 端的网络设备用发送窗口来寻址 RLC数据块, 在发送窗口中, RLC 数据块被分别表示为未发送、 等待确认、 正确接收或错误接收状态。 如果一个 RLC数据块没有被发送过,则被标识为未发送状态,该 RLC 数据块一旦被发送则标识为等待确认状态。 当接收到来自移动台 MS 下行分组的 ACK (肯定确认) /NACK (否定确认) 消息后可获知前 面发送的 RLC数据块是否被移动台 MS正确接收, 并相应更新发送 窗口。 如果 RLC数据块被正确接收, 则该 RLC数据块被标识为正确 接收状态(ACK ); 如果接收错误或丟失, 则该 RLC数据块被标识为 错误或丟失接收状态 (NACK ); 如果没有接收到应答信息, 则保持 等待确认状态。 发送窗口更新后, 会滑动到第一个未应答的 RLC数 据块的位置。
轮询的频率会根据无线链路的情况自适应调整, 当 BLER ( Block Error Ratio, 错块率)升高, 网络设备中的 PCU会增加轮询频率; 反 之, 网络设备中的 PCU会降低轮询频率。 另外, 轮询还需要考虑 RLC 数据块的调度频率, 图 2为 ARQ机制下假设轮询间隔为 12 RLC数据块 的轮询过程, 包括以下步骤:
步骤 s201 , 网络设备向移动台发送 RLC数据块, RLC数据块中包 括 4个无线块; 其中, 可能有些无线块丟失或传输错误。
步骤 s202, 间隔 12个 RLC数据块时, 网络设备向移动台发送 RLC 数据块, 该 RLC数据块包括 ACK/NACK轮询请求。
步骤 s203 ,移动台向网络设备发送轮询 ACK/NACK响应消息, 网 络设备获知下行链路信道质量及所发送 RLC数据块的接收情况。
步骤 s204, 网络设备向移动台重传错误 /丟失块。
由于移动台的 RLC层需收集 LLC帧所包含的全部 RLC数据块 才能组包上传给本端高层。 网络设备通过轮询后移动台轮询 ACK/NACK消息获知移动台是否正确收到所有下行 RLC数据块。 因 轮询是间隔产生, 当出现块丟失或错误时, 网络不能立刻知道并重传 错块或丟失的块, 只有等到轮询且移动台上报 ACK/NACK消息后才 会重传。 在实际情况中, PCU知道下行错块或丟失块需要约 150 ~ 250ms的时间, 产生了较大的传输延时。
轮询除了上述获得移动台接收下行数据块的情况的作用外,还需 要周期性(例如 480ms )的通过轮询来得到移动台的链路质量的测量 报告, 该报告也在分组下行 ACK/NACK消息中携带。 轮询的设置通 过 RLC/MAC块头中的 ES/P设置来实现, ES/P字段标识及对应的反 馈请求描述含义如表 1 :

Figure imgf000005_0001
其中, RRBP ( Relative Reserved Block Period, 相关保留块周期) 字段表明 MS收到轮询时, 网络设备给 MS预留的发送 ACK/NACK 消息的资源, 在 RRBP字段指出的周期届满, MS可以不再监视 USF ( Uplink State Flag, 上行状态标识), 直接发送消息, 因为网络在 RRBP字段中已经把这个周期内的数据块资源分配给了 MS。
由于 GERAN中网络设备的发送窗口和接收窗口最大均为 1024, 而每条控制消息的长度为 181bits , 除去包头开销等, 分组下行 ACK/NACK消息 (Packet downlink ACK/NACK message )所剩的能 够供 bitmap (位图)使用的空间在 128bits左右, 如果接收窗口超过 控制消息携带 bitmap 的最大值, 则一条控制消息不能携带整个窗口 的状况, 则需要对窗口进行分段上报, 所以网络设备就用区分是轮询 FPB ( First Partial Bitmap, 第一部分位图)还是 NPB ( Next Partial Bitmap, 下一部分位图)来控制 MS上报窗口的位置, 以此来获得整 个窗口的接收情况。 由于网络要求 MS测量报告上报的频率要小于网络要求 MS进行 bitmap反馈的频率, 且过频繁的测量报告没有实际作用, 同时测量报 告会占用 ACK/NACK消息中超过一半的空间, 降低 ACK/NACK消 息携带 bitmap的效率, 所以 MS没有必要在每次轮询时都反馈测量 报告。
为了能使网络设备能快速获知数据块的接收情况, FANR ( Fast ACK/NACK Report, 快速 ACK/NACK )机制作为轮询机制的补充。 与传统 ACK/NACK机制不同, 快速 ACK/NACK为了能快速的对网络 设备进行响应, 不是釆用传统的 ACK/ACK响应消息来发送响应, 而 是把 ACK/NACK信息和数据块在一个 RLC/MAC块中发送, 这种 ACK/NACK消息称为 PAN ( Piggybacked ACK/NACK , 数据块携带 ACK/NACK )。 这样嵌入 PAN的无线块共有三部分组成, 如图 3所示, 包括: 数据块头 (RLC/MAC Header ), PAN和数据载荷 ( RLC data block ), 其中, 字母 0表示为可选。
在新的结构中 PAN为可选项, RLC数据块中是否包含 PAN在块头 中指示, RLC数据块可以有一到两块 MCS7-9 ( Modulation and Coding Scheme, 调制编码方式)。
PAN的长度固定, 为 24bits, 每个 RLC数据块中可以有 1个 PAN。 PAN的结构如表 2所示:
表 2:
Figure imgf000006_0001
- SSN长度 - 1
在引入 FANR后,原有轮询机制也有所变动,在原有轮询机制的 基础上, 增加网络控制的快速 ACK/NACK, 就是网络轮询 MS, MS 可以釆用快速 ACK/NACK消息(也就是 PAN )来应答。 表 1中所表 示的原有的轮询机制只有三种选项 ( ES/P 为 01 表示 EGPRS PACKET DOWNLINK ACK/NACK 消息包括 FPB; ES/P 为 10表示 EGPRS PACKET DOWNLINK ACK/NACK 消息包括 NPB; ES/P 为 11表示 EGPRS PACKET DOWNLINK ACK/NACK消息包括 信道质量测量报告, 如果有剩余空间则携带 NPB ), 由于轮询需要完 成定期的链路质量测量报告上报的功能, 因此第三种 NPB和测量报 告一起上报的选择必须保留, 将第二种选择(轮询 NPB ) 改为网络 控制的快速 ACK/NACK (即釆用轮询 PAN类型的 FPB )。 更改后的 轮询机制如表 3所示:
表 3 :
Figure imgf000007_0001
数据块中是否包含 PAN可以通过 RRBP字段中的一个 bit来指 示, RRBP字段有一位有效, 有两个反应时间可以选择。
在实现本发明的过程中,发明人发现在原有的轮询机制下可以一 个 FPB和一个 NPB就可以完成整个窗口的上 由于现有方案去掉 了原来表 1中的 10选项, 即先优先上报 NPB, 如果有剩余空间, 则 携带测量报告的选项, 根据修改后的表 3 , 只能釆用先报测量报告, 然后捎带 bitmap的方式上报 NPB , 这样每个 ACK/NACK消息中所 带有的 bitmap就比原来优先报 NPB的选择少了至少一半。 原来一条 消息就可以发送, 现在可能需要两条以上的测量报告加捎带 bitmap 的消息。 所以现有的方案极大的降低了传输效率。 发明内容

本发明实施例提供了一种轮询方法,如图 4所示,包括以下步骤: 步骤 s401 ,移动终端接收网络设备发送的下行数据接收状态的轮 询请求, 该轮询请求中包括对移动终端上报的下行数据接收状态的, 包括开始位置和上报方式的控制信息。
其中, 上报方式可以为: 分组数据下行链路 ACK/NACK消息上 报; 或数据块携带 ACK/NACK消息上报。 网络设备发送轮询请求的 数据块的块头中携带轮询请求。
步骤 s402, 移动终端按照网络设备要求的上报方式, 例如: 釆用 分组数据下行链路 ACK/NACK ( EGPRS Downlink ACK/NACK ) 消 息或者数据块携带 ACK/NACK消息 (PAN ) 消息, 把网络设备所要 求部分的下行数据的接收状态上报给所述网络设备。 其中, 如果网络 设备指出所要求上报信息窗口的开始位置,移动终端可以根据本移动 终端的运行状态确定釆用 EGPRS Downlink ACK/NACK 消息或者是 PAN来上报 FPB ( First Partial Bitmap, 第一部分位图)或 NPB ( Next Partial Bitmap, 下一部分位图); 或根据轮询中要求的方式上 4艮选项 中的上报指示确定釆用 EGPRS Downlink ACK/NACK 消息或者是 PAN来上报 FPB或 NPB。 当移动设备获得 PAN上报方式时, 该上报 方式可以由 RLC/MAC数据块中相关保留块周期 RRPB字段设置、或 由 RLC/MAC数据块头中的 ES/P设置。
当移动设备的接收窗口大于上报消息长度时,继续要对接收窗口 的状态信息进行分段上报分为 FPB和 NPB上报。 网络设备向移动终 端发送首次轮询时, 指示移动终端以 PAN方式或分组数据下行链路 ACK/NACK消息上报方式上报 FPB; 然后, 网络设备向移动终端再 次发送轮询请求, 指示移动终端以 PAN 方式或分组数据下行链路 ACK/NACK消息方式上报 NPB; 依次类推, 直至接收到整个接收窗 口的 RLC数据块状态, 可获知前面发送的 RLC数据块是否被移动终 端正确接收, 并相应更新发送窗口。 如果 RLC数据块被正确接收, 则该 RLC数据块被标识为正确接收状态( ACK ); 如果接收错误或丟 失, 则该 RLC数据块被标识为错误接收状态(NACK ); 如果没有接 收到应答信息, 则保持等待确认状态。 发送窗口更新后, 会滑动到第 一个未应答的 RLC数据块的位置。快速 ACK/NACK方式可以釆用现 有技术中的 PAN方式实现。 备可以是基站、 无线网络控制器等, 移动终端可以是移动台或其它移 动接入设备。
本发明实施例一, 保留原有的轮询机制不变, 利用 ES/P无效资源 字段结合 RRBP字段来指示釆用 PAN上报 FPB。
网络设备中向移动终端连续发送 RLC/MAC数据块, 网络设备中 的 PCU会以一定周期向移动终端发送反馈下行数据接收状态的轮询 请求, 该轮询请求一般会携带于 RLC数据块中, 即将轮询请求设置在 下行链路 RLC/MAC数据块块头 (如图 1所示) 中的 ES/P字段。 其中, ES/P字段包括 2比特, 具体设置含义如表 4所示,
表 4: ES/P 反馈请求描述(Poll轮询)
00 无意义 (RRBP字段无效)
01 EGPRS PACKET DOWNLINK ACK/NACK 消息包含 FPB
(First Partial Bitmap), 如果有剩余空间, 则携带测量报告
10 EGPRS PACKET DOWNLINK ACK/NACK 消息包含 NPB
(Next Partial Bitmap), 如果有剩余空间, 则携带测量报告
11 EGPRS PACKET DOWNLINK ACK/NACK消息包含信道质量 测量报告, 如果有剩余空间则携带 NPB
表 4中 ES/P为 "00"时,无意义,代表 RRBP字段无效; ES/P为 "01" 时 , 代 表 指 示 移 动 终 端 返 回 EGPRS PACKET DOWNLINK ACK/NACK 消息, 该消息中包括 FPB, 且当有剩余空间, 则携带测量报告; ES/P为 "10" 时, 代表指 示移动终端返回 EGPRS PACKET DOWNLINK ACK/NACK 消息,该 消息中包括 NPB, 且当有剩余空间, 则携带测量 ^艮告; ES/P为 "11" 时 , 代 表 指 示 移 动 终 端 返 回 EGPRS PACKET DOWNLINK ACK/NACK 消息,该消息中包括信道 质量测量报告, 如果有剩余空间则携带 ΝΡΒ。
上述功能与现有技术相同, 此时还需要利用 RLC数据块头中的 RRBP字段指示 PAN类型上报, 当 ES/P为 "00" 时, RRBP字段无效, 可以用该字段中的 1比特指示轮询 PAN。 RRBP字段含义如表 5所示。
Figure imgf000012_0001
在表 4的基础上,将 ES/P的无效字段 00, 结合 RRPB字段指示通过 PAN类型上报 FPB。例如,在表 5中, 当 RRBP字段中指定比特 1为 0时, 代表没有轮询, 指定比特 1为 1时, 代表指示移动终端釆用 PAN上报 FPB。 因此, 相比于表 1和表 3 , 既实现了利用 ACK/NACK 消息上才艮 FPB、 利用 ACK/NACK 消息上报 NPB, 又实现了利用 PAN上报 FPB。 例如, 收到这种类型的轮询请求时, 网络给手机的预留资源固定, 如 带 ACK/NACK ) 消息上报 FPB ( ES/P为 00, RRPB的 bitl为 1时) 、 或 釆用分组数据下行链路 ACK/NACK消息上报 FPB ( ES/P为 01时)、 或 釆用分组数据下行链路 ACK/NACK消息上报 NPB ( ES/P为 10时)、 或 釆用分组下行链路数据上报信道质量报告捎带 NPB ( ES/P为 11时) 。
此方法实质上是将 2bit的 ES/P和 lbit的 RRBP联合作为 3bit的信息 域来考虑, 除去无意义选项, 可以指示四种轮询类型, 即 PAN (数据 块携带 ACK/NACK ) 消息上报 FPB、 或釆用分组数据下行链路 ACK/NACK消息上报 FPB、 或釆用分组数据下行链路 ACK/NACK消 息上报 NPB、 或釆用分组下行链路数据上报信道质量报告捎带 NPB, 且每种轮询类型最多使用两个反应时间,即控制信息所表示的全部指 示项中, 除去无意义选项, 每种轮询类型最多有两个。
本发明实施例二, 网络设备只指出需要获得的接收状态位图的位 置是 FPB或 NPB ,具体釆用传统的分组下行链路 ACK/NACK消息还是 PAN来上报 FPB或 NPB, 由移动终端来决定。
网络设备向移动终端发送 RLC数据块, 网络设备中的 PCU会以一 定周期向移动终端发送对下行数据接收状态的轮询请求,该轮询请求 一般会携带于 RLC数据块中, 即将轮询请求设置在下行链路 RLC数据 块头(如图 1所示) 中的 ES/P字段。 其中, ES/P字段包括 2比特, 具体 设置含义如表 6所示,
表 6:
ES/P 反馈请求描述(Poll轮询)
00 无意义 (RRBP字段无效)
01 FPB -具体釆用 EGPRS PACKET DOWNLINK ACK/NACK消 息还是 PAN来上报由手机根据当时的情况来决定
10 NPB -具体釆用 EGPRS PACKET DOWNLINK ACK/NACK消 息还是 PAN来上报由手机根据当时的情况来决定
11 EGPRS PACKET DOWNLINK ACK/NACK消息包含信道质量 测量报告, 如果有剩余空间则携带 NPB
表 6中 ES/P为 "00"时,无意义,代表 RRBP字段无效; ES/P为 "01" 时, 代表网络设备指示需要获得的窗口是 FPB, 移动终端根据当时运 行状况选择通过返回 EGPRS PACKET DOWNLINK ACK/NACK 消 息、 或 PAN方式上报 FPB; ES/P为 "10" 时, 代表网络设备指示需要 获得的窗口是 NPB , 移动终端根据当时运行状况选择通过返回 EGPRS PACKET DOWNLINK ACK/NACK 消息、 或 PAN方式上才艮 NPB ; ES/P 为 " 11 " 时 , 代表指 示 移 动 终端 返 回 EGPRS PACKET DOWNLINK ACK/NACK 消息, 该消息中包括信道 质量测量报告, 如果有剩余空间则携带 ΝΡΒ。
其中, 当网络设备的接收窗口和发送窗口的长度大于消息长度 时, 网络设备指示移动终端返回 FPB后, 还需要指示该移动终端返回 ΝΡΒ; 当窗口长度小于消息长度时, 网络设备只需要指示移动终端返 回 FPB即可。 当然, 为了提高数据传输的效率, 移动终端可以根据位 图的大小等需求, 确定釆用传统 ACK/NACK消息上报或釆用快速 ACK/NACK消息上报。 才艮 FPB、 或釆用分组数据下行链路 ACK/NACK消息上报 FPB、 或釆用 分组数据下行链路 ACK/NACK消息上报 NPB、或釆用 PAN (数据块携 带 ACK/NACK )上报 NPB、或釆用分组下行链路数据上报信道质量报 告捎带 NPB。
本发明实施例三, 用 PAN上报 FPB , 用现有的分组下行链路 ACK/NACK消息上报 NPB。 网络设备向移动终端发送 RLC数据块, 网 络设备中的 PCU会以一定周期向移动终端发送对下行数据接收状态 的轮询请求, 该轮询请求一般会携带于 RLC数据块中, 即将轮询请求 设置在下行链路 RLC数据块头 (如图 1所示) 中的 ES/P字段。 其中, ES/P字段包括 2比特, 具体设置含义如表 7所示:
Figure imgf000015_0001
表 7中 ES/P为 "00" 时, 无意义, 代表 RRBP字段无效; ES/P 为 " 01 " 时 , 代 表 指 示 移 动 终 端 返 回 EGPRS PACKET DOWNLINK ACK/NACK 消息, 该消息中包括 FPB, 且当有剩余空间, 则携带测量报告; ES/P为 "10" 时, 代表指 示移动终端釆用轮询 PAN上报 FPB; ES/P为 "11" 时, 代表指示移 动终端返回 EGPRS PACKET DOWNLINK ACK/NACK 消息,该消息 中包括信道质量测量报告, 如果有剩余空间则携带 ΝΡΒ。
本实施例中, 相对于表 3 , 移动终端可以指示三种轮循类型 (包 括两种上报 ΝΡΒ和一种上报 FPB ), 包括: 可以釆用 PAN (数据块携 带 ACK/NACK )上报 FPB ( ES/P为 10时)、 或釆用分组数据下行链 路 ACK/NACK消息上报 NPB ( ES/P为 01时)、或釆用分组下行链路 数据上报信道质量报告捎带 NPB ( ES/P为 11时)。
本发明实施例还可参考实施例一中的方法, 联合考虑 ES/P 和 RRBP, 利用 RRBP的无效资源增加一种轮询类型即釆用分组数据下 行链路 ACK/NACK消息上报 FPB, 除去无意义选项, 对每种轮询类 型最多指示两种反应时间, 即控制信息所表示的全部指示项中, 除去 无意义选项, 每种轮询类型最多有两个。
本发明实施例还提供了一种轮询系统, 如图 5所示, 包括网络设 备 100和移动终端 200, 网络设备 100, 向移动终端 200发送下行数 据接收状态反馈的轮询请求,该轮询请求中包括上报开始位置和上报 方式的控制信息; 移动终端 200, 接收网络设备 100发送的下行数据 接 收 状 态 的 轮 询 请 求 , 并 且 釆 用 EGPRS PACKET DOWNLINK ACK/NACK 消息或者 PAN 来上报 FPB或 NPB给网络设备 100。
其中, 网络设备 100具体包括: 轮询设置单元 110, 用于设置下 行数据接收状态的轮询请求,轮询请求包括上报位置和上报方式的控 制信息; 轮询发送单元 120, 用于向移动终端发送轮询请求; 上报方 式设置单元 130, 用于确定网络下发的轮询请求中要求移动设备釆用 的上报方式。
移动终端 200具体包括: 轮询接收单元 210, 用于接收来自网络 侧的反馈下行数据接收状态的轮询请求; 信息上报单元 220, 用于上 报 FPB或 NPB给网络设备; 上报方式获取单元 230, 用于从轮询请 求中获取上报方式; 或根据移动终端的运行情况确定上报方式, 该上 报方式可以釆用传统的 EGPRS Downlink ACK/NACK 消息或者是 PAN上报。
本发明的实施例中,在实现网络设备可以控制移动终端釆用数据 块携带 ACK/NACK消息上报的同时,保留移动终端可以釆用携带 NPB 的分组数据下行链路 ACK/NACK消息来上报下行数据的接收状态的 选项, 因此, 可以在大窗口或小窗口的情况下都能艮好的工作, 比现 有方案更灵活, 有更好的空口利用效率。
通过以上的实施方式的描述, 本领域的技术人员可以清楚地 了解到本发明可借助软件加必需的通用硬件平台的方式来实现, 当然也可以通过硬件, 但很多情况下前者是更佳的实施方式。 基 于这样的理解, 本发明的技术方案本质上或者说对现有技术做出 贡献的部分可以以软件产品的形式体现出来, 该计算机软件产品 存储在一个存储介质中, 包括若干指令用以使得一台计算机设备 (可以是个人计算机, 服务器, 或者网络设备等)执行本发明各 个实施例所述的方法。
以上公开的仅为本发明的几个具体实施例, 但是, 本发明并非局 限于此,任何本领域的技术人员能思之的变化都应落入本发明的保护 范围。
