Description

数据传输方法和装置
技术领域 本发明涉及通信技术， 尤其涉及一种数据传输方法和装置。
背景技术
随着网络技术的不断发展， 通用分组无线业务 （General Packet Radio Service, 简称： GPRS ) 得到了广泛的应用。
GPRS中所有的数据传输都是通过建立临时块流 （Temporary Block Flow, 简称： TBF)来完成的， 一个 TBF用于完成若干用户数据 （如点击网页上的一 个链接所产生的数据） 的传输。 对于上行 TBF, 由于多个终端可能复用在同 一个分组数据信道 （Packet Data Channel , 简称 PDCH) 上， 为避免冲突， 网络必须通过一定的方式决定某个 PDCH 的每一个上行无线块资源属于哪一 个终端 （即哪一个终端可以在该上行无线块上发送数据） 。
目前 GPRS网络中采用的是基于上行状态标识 （Upl ink State Flag, 简 称： USF) 的上行资源分配方式： 网络在建立上行 TBF 时， 给终端分配一个 USF, 终端监视下行 PDCH上的无线块， 如果某个无线块的头部中携带的 USF 与分配给自己的 USF是相同的，则表明该终端可以在该下行 PDCH对应的上行 PDCH的下一个或多个无线块进行数据传输。
但是， 由于 USF只携带 3个信息比特， 最多只能存在 2的 3次方个不同 的 USF, 即一个上行 PDCH最多只能复用 8个终端。 当大量终端需要同时或在 同一个时间段内接入时， 则会因为 PDCH资源不足而被拒绝接入， 并因为终端 的反复尝试接入导致更多不必要的接入冲突和接入失败， 降低了无线接入的 成功率， 因此， 如何增加上行 PDCH复用的终端个数以提升系统容量成为迫切 需要解决的问题。 发明内容 本发明提供一种数据传输方法和装置， 以增加上行 PDCH复用的终端个 数， 提升系统容量。 第一方面， 提供一种数据传输方法， 包括：

具体实施方式
图 1为本发明数据传输方法实施例的应用架构图， 在当前的例如通用分 组无线服务技术 （General Packet Radio Service, 简称： GPRS)和增强 GPRS
(Enhanced GPRS , 简称： EGPRS ) 中均是以块为单位来传输上下行数据的。 基站向终端传输的是下行块， 终端向基站传输的是上行块。 数据传输所在的 时频资源即 PDCH, 可以被多个终端同时占用， 例如一条上行 PDCH可以被图 1 中所示的终端 A和终端 B占用。
其中， 终端在向基站发送上行块时， 不能随意发送数据， 必须等待基站 调度才可以发送上行块； 例如， 当终端想要向基站发送上行数据时， 调度方 式可以包括如下步骤：
参数下发阶段： 终端会向基站发送用于表示自己将发送数据的请求， 基 站据此与终端之间建立上行 TBF, 向终端发送控制消息 （例如， immediate assignment控制消息） ； 该控制消息主要是用于向终端发送一些数据传输所 需要的参数， 包括： USF (终端判断基站是否调度自己上行时需要依据该参 数） 、 TSC (终端根据该 TSC解码下行块） 等； 此外， 如果基站想要向终端发 送下行数据， 则基站可以与终端建立下行 TBF, 并在控制消息中向终端下发 临时块流标识 （Temporary Flow Identity, 简称： TFI ) (终端根据 TFI判 断下行块是否是发送给自己的） 等；
下行调度阶段： 基站在向终端发送上述控制消息后， 将向终端发送下行 块； 该下行块包括块头部分 （Header) 和数据部分 （Data) ， 基站在下行块 的块头部分携带 TFI和 USF, 并在下行块的数据部分携带 TSC, 其中的 TFI是 该下行块所下发的终端对应的 TFI; 该下行块中还包括上行调度参数， 该上 行调度参数是用于表示将要调度下一个上行块发送数据的终端的， 终端可以 根据该上行调度参数判断当前基站是否调度自己发送上行块。
上行发送阶段： 如果终端根据上述的下行块中包括的上行调度参数， 确 定基站调度上行的终端是自己， 则终端将在下一个上行块向基站发送数据。 此外， 如果该终端还与基站之间建立了下行 TBF, 则终端还会根据下行块块 头中包括的 TFI , 判断该下行块的数据部分是否是发送给自己的， 如果下行 块块头中的 TFI与参数下发阶段基站分配的 TFI相同， 则表明这是发送给自 己的， 终端将继续解码下行块的数据部分。
即， 基站和终端之间， 如果基站有数据要下发至终端则两者之间建立下 行 TBF, 终端根据下行块块头中的 TFI判断下行块是否是基站发送给自己的； 如果终端有数据要发送至基站则两者之间建立上行 TBF, 终端根据下行块块 头中的上行调度参数 （例如包括 USF) 判断基站是否调度自己上行。
本实施例中， 为了使得上行复用的用户数增加， 对上述的上行调度参数 进行了设计， 如下通过与现有技术相比较进行说明： 现有技术的上行调度参 数仅仅是 USF, 通过 USF来区分不同的终端， 例如， 基站如果想调度图 1中 的终端 A和终端 B上行复用 PDCH, 则在下行块中携带终端 A对应的 USF1 , 终 端 A发现该下行块中携带的 USF1即是在参数下发阶段基站分配的 USF1 , 则 在下一个上行块开始发送数据给基站； 同理， 基站也会在发送给终端 B的下 行块中携带终端 B对应的 USF2, 终端 B根据该 USF2开始上行发送数据。 即 现有的是通过不同的 USF来区分不同的终端， 由于 USF仅有 3比特， 所以最 多有 8个不同的 USF, 也导致仅能最多 8个终端上行复用。 而本实施例， 将 上行调度参数包括： USF和 TSC,即通过 USF+TSC的整体区分终端，其中包括： 至少两个终端的 USF相同且 TSC不同的情况。
具体的， 参见图 1， 终端 A对应的上行调度参数是 USF+TSC1 , 终端 B对 应的上行调度参数是 USF+TSC2 , 即这两个终端就是 USF相同且 TSC不同。 基 于此， 基站在参数下发阶段为终端分配相关参数时， 就以 USF+TSC1来区分终 端， 比如， 基站可以向终端 A下发 USF和 TSC1 , 向终端 B下发 USF和 TSC2。 在下行调度阶段时， 基站如果将调度终端 A上行发送数据， 则会在下行块中 携带上述为终端 A分配的 USF和 TSC1 ; 终端 A接收到该下行块后， 就需要确 定下行块中的 USF和 TSC1 ,与在参数下发阶段基站分配给自己的 USF和 TSC1 是否相同， 如果相同则终端 A可以确定基站在调度自己。 因此， 基站在下行 块中携带的上行调度参数就是以 USF+TSC的组合来标识终端， 而不是现有仅 根据 USF, 终端也以 USF+TSC的组合来判断基站是否调度上行， 而不是现有 仅根据 USF判断。
本实施例的基站调度上行终端的方式， 很明显可以增加同时复用的用户 数（即终端数） ， 比如， 假设基站调度两个终端复用 PDCH, 则需要使用 USF1 和 USF2区分；而采用本实施例的方式， USF1和 USF2分别结合两个不同的 TSC, 即 USF1+TSC1、 USF1+TSC2、 USF2+TSCK USF2+TSC2 , 这样即使只有两个 USF (USF1和 USF2 ) ， 由于结合了 TSC的组合， 可以用于区分四个终端， 基站就 可以调度四个终端复用 PDCH。
下面通过几个实施例来说明本发明的数据传输方法：
实施例一
图 2为本发明数据传输方法一实施例的流程示意图， 本实施例的方法可 以是基站执行； 如图 2所示， 该方法可以包括：
201、 向至少两个终端分配上行调度参数， 所述上行调度参数包括上行状 态标识 USF和训练序列 TSC, 使得所述至少两个终端具有相同的 USF和不同 的 TSC, 所述至少两个终端复用在同一个分组数据信道 PDCH上。
其中， 当基站或者终端有数据要发送时， 基站都会向终端下发上行调度 参数， 基站是将为终端分配的上行调度参数发送给对应的终端； 例如， 为终 端 A分配的 USF+TSC1， 为终端 B分配的是 USF+TSC2 , 则基站将上行调度参数 USF+TSC1发送给终端 A， 将上行调度参数 USF+TSC2发送给终端 B。 基站向终端发送上述的上行调度参数的方式， 例如可以是， 基站向所述 至少两个终端分别发送建立临时块流的控制消息， 在终端与基站之间建立 TBF, 所述控制消息中携带向所述终端分配的所述上行调度参数； 例如， 当有 至少两个终端都想向基站上行发送数据时， 基站可以向该至少两个终端分别 发送控制消息。 该控制消息中包含： 基站分配给该终端的 USF和 TSC等。 本 实施例将 USF和 TSC称为上行调度参数， 即控制消息中携带上行调度参数。
并且，本实施例中的至少两个终端，可以是具有相同的 USF和不同的 TSC; 例如图 1所示的， 终端 A和终端 B的 USF相同但 TSC不同。 此外， 本实施例 中的至少两个终端是复用在同一个 PDCH上， 比如图 1中所示的， 一条上行 PDCH可以被图 1中所示的终端 A和终端 B占用。
202、 在所述 PDCH上发送下行块， 所述下行块中携带的上行调度参数只 包含分配给所述至少两个终端中一个终端的上行调度参数， 以使得接收到所 述下行块的终端根据所述下行块中携带的所述上行调度参数和分配给所述接 收到所述下行块的所述终端的上行调度参数确定是否发送上行块。
其中， 基站向终端发送的下行块中， 携带该下行块发送的目的终端对应 的 TFI , 以使得终端据此识别该下行块是发送给自己的； 此外， 基站还在该 下行块中携带调度上行的终端的上行调度参数， 以使得接收到该下行块的终 端根据下行块中携带的上述上行调度参数、 以及从基站接收到的分配给接收 到所述下行块的终端的上行调度参数， 判断是否接收到了基站的调度上行指 示， 即接收到该下行块的终端会根据所述下行块中携带的上行调度参数和基 站分配的上行调度参数确定是否向基站发送上行块。
例如， 基站向图 1中的终端 A发送的下行块中包括： 在 201中为终端 A 分配的 USF和 TSC1。 其中， 可以将 USF携带在下行块的块头部分， 将 TSC携 带在下行块的数据部分， 不改变块头的结构。 基站发送的所述下行块可能是 发送给终端 A之外的其他终端的， 所以所述其他终端可以根据下行块块头中 的 TFI判断该下行块是否是发送给自己的。
进一步的， 基站在 PDCH上发送下行块之后， 如果终端根据下行块中的上 行调度参数确认基站在调度自己上行， 则终端会向基站发送上行块； 基站可 以接收该终端在 PDCH上发送的上行块，所述上行块中包括基站为该终端分配 的上行调度参数中的 TSC。 基站可以使用为终端分配的所述 TSC解码所述上 行块获得终端发送的上行数据。
本实施例的数据传输方法， 通过向至少两个终端分配上行调度参数， 使 得该至少两个终端具有相同的 USF和不同的 TSC, 实现了利用不同的 TSC区 分具有相同 USF的终端， 而不再是仅仅根据不同的 USF来区分终端， 增加了 上行 PDCH可以复用的终端个数， 提升了系统容量。
实施例二
图 3为本发明数据传输方法另一实施例的流程示意图， 本实施例的方法 可以是终端执行； 如图 3所示， 该方法可以包括：
301、终端接收基站分配给所述终端的上行调度参数， 所述上行调度参数 包括上行状态标识 USF和训练序列 TSC;
例如， 终端可以从基站发送的建立临时块流的控制消息中获得携带的所 述上行调度参数， 该控制消息中包含： 基站分配给该终端的 USF和 TSC等。
302、 终端在分组数据信道 PDCH上接收所述基站发送的下行块； 其中， 基站向终端发送的下行块中， 携带该下行块发送的目的终端对应 的 TFI , 以使得终端据此识别该下行块是发送给自己的； 此外， 基站还在该 下行块中携带调度上行的终端的上行调度参数。
303、终端根据所述下行块中携带的上行调度参数和所述基站分配给所述 终端的所述上行调度参数确定是否发送上行块， 若是， 则在所述 PDCH上向所 述基站发送上行块。
可选的， 在本步骤中， 终端根据所述下行块中携带的上行调度参数和所 述基站分配给所述终端的所述上行调度参数， 确定是否发送上行块， 可以采 用如下方式：
终端若确定下行块中的 TSC与基站分配给终端的上行调度参数中的 TSC 相同，且所述下行块中的 USF与基站分配给所述终端的上行调度参数中的 USF 相同时， 则终端可以确定向所述基站发送上行块。
进一步的， 终端在判断上述的下行块中的 TSC和 USF与基站分配的上行 调度参数中的 TSC和 USF分别相同时， 也可以采用多种方式。
一种可选方式是， 终端可以使用基站分配给所述终端的所述上行调度参 数中的 TSC解码下行块， 如果解码成功并获得下行块中的 USF, 则终端就可 以确定所述下行块中的 TSC与所述基站分配给所述终端的所述上行调度参数 中的所述 TSC相同； 并且终端判断所述下行块中的所述 USF与所述基站分配 给所述终端的所述上行调度参数中的所述 USF是否相同， 若是， 则确定所述 下行块中的所述 USF与所述基站分配给终端的所述上行调度参数中的所述 USF相同。
具体的， 以图 1中的终端 A为例， 则终端 A以 TSC1解码下行块。 在解码 下行块的块头后， 得到块头中携带的 TFI和 USF, 例如上述的， 某些终端可 以根据 TFI , 判断该下行块是否是发送给自己的， 而该某些终端是在之前已 经建立了与基站之间的下行 TBF, 并且接收了基站通过控制消息下发的下行 TFI , 所以该某些终端知道基站要发送数据给自己， 此时就可以根据下行块块 头中的 TFI判断该 TFI与基站分配的 TFI是否相同， 若相同则确定是发送给 自己的。 而终端 A是要向基站上行传输数据， 终端 A与基站之间建立了上行 TBF,并且接收了基站通过控制消息下发的上行 USF和 TSC (即上行调度参数）， 则此时终端 A可以根据下行块中的上行调度参数判断基站是否在调度自己上 行。
需要说明的是， 只有当终端用于解码的 TSC与下行块中携带的 TSC相同 时， 才能正确解码出当前的下行块； 比如， 终端 A采用 TSC1解码下行块， 则 如果下行块的数据部分携带的 TSC是该 TSC1时，终端 A才能正确解码下行块 的块头， 得到上述的 TFI和 USF; 否则， 终端 A不能解码下行块， 比如如果 下行块的数据部分携带的 TSC是 TSC2 , 则终端 A不能解码获得上述的 TFI和 USF。
如上所述的， 终端只要能利用 TSC解码获得下行块块头中的 USF, 则已 经表明该下行块中的 TSC与基站分配给终端的 TSC相同， 那么此时如果下行 块中的 USF也与基站分配的 USF相同， 则可以确定下行块中的 USF和 TSC与 基站分配的上行调度参数相同， 具体是下行块中的 USF与所述基站分配给所 述终端的上行调度参数中的 USF相同， 并且下行块中的 TSC与所述基站分配 给所述终端的上行调度参数中的 TSC相同， 也即基站在调度该终端上行。
另一种可选方式是， 终端可以使用所述基站使用的各 TSC尝试解码所述 下行块， 确定所述各 TSC中能够解码所述下行块的目标 TSC;
若所述目标 TSC与所述基站分配给所述终端的所述上行调度参数中的所 述 TSC相同， 并且通过所述目标 TSC解码所述下行块获得的所述下行块中的 所述 USF与所述基站分配给所述终端的所述上行调度参数中的所述 USF相同， 则所述终端可以确定下行块中的 TSC与基站分配给所述终端的所述上行调度 参数中的所述 TSC相同， 且所述下行块中的所述 USF与所述基站分配给所述 终端的所述上行调度参数中的所述 USF相同。
进一步的， 终端在确定基站调度自己上行后， 终端将在下一个上行块向 基站发送数据， 该上行块的数据部分包括基站为终端分配的 TSC。 上行块包 括 4个 burst , 构成数据块的 burst是普通脉冲（Normal Burst , 简称： NB) ， 每个 NB包含 26比特的 TSC。 该 NB的结构可以参见图 4， 图 4为本发明数据 传输方法另一实施例中的普通脉冲示意图。
而基站在接收到该终端发送的上行块时， 将使用之前为终端分配的 TSC 解码上行块获得终端发送的上行数据。
本实施例的数据传输方法， 终端接收基站分配的上行调度参数， 所述上 行调度参数包括 USF和 TSC; 终端接收基站发送的下行块， 并根据下行块中 携带的上行调度参数和基站分配给该终端的上行调度参数确定是否发送上行 块， 若是， 则向基站发送上行块， 实现了终端能够同时根据 USF和 TSC确定 是否发送上行数据， 从而实现了在上行调度过程中利用不同的 TSC区分具有 相同 USF的终端，而不再是仅仅根据不同的 USF来区分终端，增加了上行 PDCH 可以复用的终端个数， 提升了系统容量。
实施例三
图 5为本发明数据传输方法又一实施例的流程示意图， 本实施例中， 旧 终端 （即仅依据 USF判断基站是否调度自己上行的终端） 在接收到基站发送 的本实施例的不同 TSC时， 也能够正常工作， 如图 5所示， 包括：
501、 基站向终端分配上行调度参数， 所述上行调度参数包括： 上行状态 标识 USF和训练序列 TSC;
其中， 分配方法可以参见 201， 例如图 1所示的， 基站向终端 A分配 USF 和 TSC1， 向终端 B分配 USF和 TSC2。
502、 基站向终端发送下行块， 该下行块中包括 USF和 TSC1 ;
例如， 基站向终端 A发送下行块， 并且想要调度该终端 A在下一个上行 块发送数据， 则该基站可以在下行块中包括与终端 A对应的 USF和 TSC1。 503、 终端解码下行块， 得知基站调度自己上行；
其中， 仍以终端 A为例， 并且假设终端 A是旧终端， 即仅依据 USF判断 基站是否调度自己上行的终端。终端 A使用之前基站分配的 TSC1去解码下行 块， 由于下行块中携带的也是 TSC1 , 所以终端 A能够正确解码。 终端 A可以 获得下行块块头中的 TFI、 USF, 终端 A根据 USF判断， 比较该 USF与 501中 基站分配的 USF, 若两者相同， 则终端 A在下一个上行块发送自己的数据给 基站。
而对于终端 B来说， 假设终端 B也是旧终端， 终端 B使用之前基站分配 的 TSC2去解码下行块， 由于下行块中携带的是 TSC1 , 所以终端 B无法正确 解码该下行块， 则终端 B是不能够获知下行块块头中包含的 USF的， 也就不 会进行上行传输。
504、 终端向基站发送上行块， 所述上行块中包括： 基站分配的 TSC。
505、 基站使用为终端分配的 TSC解码上行块。
实施例四
图 6为本发明数据传输方法又一实施例的流程示意图， 本实施例中， 下 行块下发的终端与调度上行的终端可以不同， 假设存在终端 C和终端 D, 基 站为终端 C分配 USF1+TSC1 , 为终端 D分配 TFI2+ TSC1 , 即这两个终端的 TSC 相同， 并且基站是想将下行块下发至终端 D, 且调度终端 C上行。 如图 6所 示， 该方法可以包括：
601、 基站向终端分配上行调度参数， 所述上行调度参数包括： 上行状态 标识 USF和训练序列 TSC;
例如， 基站与终端 C之间建立上行 TBF, 并通过控制消息向终端 C分配 USF1和 TSC1 ; 基站与终端 D之间建立下行 TBF, 并通过控制消息向终端 D分 配 TFI2和 TSC1。
602、 基站向终端发送下行块， 该下行块中包括： TFI2、 USFl和 TSCl ; 例如， 基站向终端 D发送下行块， 想要调度该终端 C在下一个上行块发 送数据， 则该基站可以在下行块中包括： 与终端 D对应的 TFI2、 与终端 C对 应的 USF1和 TSC1。
603、 终端 C解码下行块， 得知基站调度自己上行， 终端 D得知该下行块 是发送给自己的； 例如， 由于基站为终端 C和终端 D分配的都是 TSC1 , 两者都采用 TSC1 解码下行块； 基站发送的下行块中包括的是 TSC1 , 则终端 C和终端 D都能够 解码获得下行块块头部分的 TFI2和 USF1。 终端 C判断块头中的 USF1与基站 分配给自己的 USF1相同，则可以确定下行块中包括的 USF和 TSC与基站分配 的上行调度参数相同 （能正确解码已经表明 TSC相同） 。
而对于终端 D, 其根据下行块块头部分的 TFI2 , 判断块头中的 TFI2与之 前基站分配给自己的 TFI2相同，则可以确定下行块上行调度参数是发送给终 端 D的， 终端 D可以继续使用 TSC1解码下行块的数据部分。
604、 终端 C向基站发送上行块。
实施例五
图 7为本发明数据传输方法又一实施例的流程示意图， 本实施例中， 假 设网络使用的 TSC有两个， 分别是 TSC1和 TSC2 ; 存在终端 E和终端 F, 终端 E建立上行 TBF, 基站为终端 E分配 USF1+TSC1 , 终端 F建立上行 TBF, 基站 为终端 F分配 TSC2+ USF1 , 终端 F还建立下行 TBF, 基站为终端 F分配 TFI 1。 本实施例是假设基站发送的下行块是发送给终端 F的， 并且要调度终端 E上 行， 且本实施例不限制终端解码下行块的 TSC, 终端可以在接收到下行块后 尝试用基站使用的多个 TSC解码下行块， 该基站使用的多个 TSC指的是终端 所在的基站使用的各 TSC。 具体的如图 7所示， 包括：
701、 基站发送下行块， 该下行块中包括： TSC1、 USF1和 TFI 1 ;
例如， 基站向终端 F发送下行块， 则需要在下行块中包括该终端 F建立 的下行 TBF对应的 TFI 1 ; 并且， 基站还想要调度终端 E在下一个上行块发送 数据， 则该基站还需要在下行块包括与终端 E的上行 TBF对应的上行调度参 数， 即 USF1和 TSC1。
702、 终端解码下行块；
例如， 对于终端 E来说， 其也可以使用基站使用的各 TSC, 例如 TSC1和
TSC2尝试解码下行块， 最终可以确定 TSC1是能够解码下行块的， 表明该下 行块携带的是 TSC1 , 该 TSC1与基站分配给终端 E的 TSC相同； 并且， 解码 出的下行块块头部分携带的 USF经过比较也是基站分配给终端 E的 USF1 , 则 终端 E可以确定基站在调度自己上行。
对于终端 F来说， 其也可以使用网络中的各 TSC1和 TSC2尝试解码下行 块， 最终可以确定 TSC1是能够解码下行块的， 表明该下行块携带的是 TSC1。 终端 F还解码出下行块中携带的是基站分配给自己的 TFI 1 , 则终端 F可以确 定该下行块是发送给自己的， 则终端 F将继续接收并解码下行块中的数据。 此外， 终端 F还解码出下行块中携带的是 USF1 , 但是如上所述的， 由于下行 块携带的是 TSC1 , 该 TSC1+USF1与基站分配给终端 F的 TSC2+ USF1不同， 则终端 F可以确定基站并没有调度自己上行， 终端 F不会上行传输数据。
703、 终端 E向基站发送上行块。
此外， 本实施例并不限制终端得知网络使用的各 TSC的方式， 可选的， 例如， 基站可以通过广播的方式将网络使用的各 TSC告知终端， 或者基站通 过向终端发送某个信令的方式告知终端；而基站所使用的各 TSC是预配置的。

进一步的， 所述数据处理单元 93， 具体用于使用所述基站使用的各 TSC 尝试解码所述下行块， 确定所述各 TSC中能够解码所述下行块的目标 TSC; 若所述目标 TSC与所述信息接收单元接收的所述上行调度参数中的所述 TSC 相同，并且通过所述目标 TSC解码所述下行块获得的所述下行块中的所述 USF 与所述信息接收单元接收的所述上行调度参数中的所述 USF相同， 则确定所 述下行块中的所述 USF与所述信息接收单元接收的所述上行调度参数中的所 述 USF相同， 且所述下行块中的所述 TSC与所述信息接收单元接收的所述上 行调度参数中的所述 TSC相同。
