随着科技的进步， 人们对移动通信业务和质量的要求也在不断提高， 因此提出向第三代 (3G)移动通信技术平滑过渡的需求， 向 3G演进的主要技 术有通用无线分组业务 (GPRS, General Packet Radio Service),增强型数据速 率全球移动通信系统演进技术（EDGE, Enhanced Data Rate for GSM Evolution), 高速电路交换数据服务 (HSCSD, High Speed Circuit Switching Data), 而研究的重点集中在利用有限的频谱资源提高传输速率和减小传输 延时。
GPRS 是在全球移动通信系统（GSM, Global System for Mobile communication) 网络中引入的分组数据交换技术。 它叠加于 GSM 系统之 上，延长了 GSM的使用寿命，它基于分组数据包的转发和信道的统计复用， 从而使现有的 GSM提供的数据业务首次从 9.6Kbps飞跃到了 100Kbps以上。 由于 GPRS仍然釆用和 GSM—样的高斯最小频移键控 (GMSK, Gaussian Minimum Shift Keying)调制方式，传输速率无法达到 3G业务要求的 2Mbps, 为了充分满足未来无线多媒体应用的带宽需求， EDGE提供了一个从 GPRS 到第三代移动通信的过渡性方案。 EDGE是一种基于 GSM/GPRS 网络的数 据增强型移动通信技术， 通常又被称为 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部分功能。
当前， EDGE理论的峰值数据速率是 473.6kbps, 在实际的网络中， 使 用 4个时隙 (timeslots)位速率可以达到 100-200kb/s。 使用多个载波， 用户的 峰值和平均的速率可以同载波数目近似的比例增长， 例如使用两个载波时， 理论上峰值速率将接近 lMb/s。
现有技术的资源指派方法中的指派消息中， 临时数据块流 (TBF， Temporary Block Flow)载波指派结构包括 TBF所指派的时隙位图的信息， ^下所示：
< Dual Carrier Multiple Downlink TBF Assignment struct > ::=

{ 0 I 1 < TIMESLOT— ALLOCATION— C2： bit (8) > }
{ 1 < Downlink TBF assignment ： < Dual Carrier Downlink TBF assignment struct > > } ** 0 ;
其中， 第一个时隙位图表示第一个载波上的资源分配， 第二个时隙位 图表示第二个载波上的资源指派， 且第一个时隙位图一直为有效的， 第二 个时隙位图为可选的， 如果标志为 1 , 则第二个时隙位图有效， 如果标志为 0, 则第二个时隙位图无效。 当第二个时隙位图有效时， 为 TBF指派第二个 载波上指派的时隙资源， 当第二个时隙位图无效时， 为 TBF指派第二个载 波使用与第一个载波相同的时隙资源。 因此， 在进行研究过程中， 发明人 发现现有技术中至少存在如下问题： 不能通过一条指派消息同时为各 TBF 指派单个载波和两个载波。 例如， 需要为三个 TBF指派载波， 第一个 TBF 需要指派在两个载波上， 第二个 TBF指派在第一个载波上， 第三个 TBF需 要指派在第二个载波上， 现有技术无法实现此种情况时的指派。 发明内容

步骤 201 : 服务 GPRS支持节点 (SGSN, Serving GPRS Support Node) 向 BSS("Base Station System" 或 "Base Station Subsystem")发送带有分组 流标志 (PFI, Packet Flow Control)的下行数据帧；
所述 PFI用来标志分组流内容 (PFC, Packet Flow Context) , PFC为数据 传输中有关服务质量 (QoS, Quality of Service)参数的描述， 由 SGSN提供给 BSS和用户， 所述 QoS参数包括数据传输速率的要求。
步骤 202: BSS收到所述下行数据帧后， 建立与下行数据帧对应的一个 或多个 TBF, 并为各临时数据块流分配单个载波和 /或两个载波上的资源； 步骤 203: BSS根据为 TBF指派的载波情况， 构造用于指示各 TBF指 派情况的指派消息， 所述指派消息包括分配了单个载波资源的临时数据块 流信息和 /或分配了两个载波资源的临时数据块流信息；
可以釆用两种方式构造下行指派消息。
釆用第一种下行指派消息方式构造的指派消息格式包括： 两个指派的 载波信息、 分配在两个载波上的下行 TBF结构、 分配在第一个载波上的下 行 TBF结构以及分配在第二个载波上的下行 TBF结构。 根据 TBF所分配 的载波，将对应的 TBF信息填充至所述分配在两个载波上的下行 TBF结构、 分配在第一个载波上的下行 TBF结构以及分配在第二个载波上的下行 TBF 结构中。 如果 TBF信息被填充至分配在两个载波上的下行 TBF结构中， 则 表示为该 TBF分配了两个载波上的资源； 如果 TBF信息被填充至分配在第 一个载波上的下行 TBF结构中，则表示为该 TBF分配了第一个载波上的资 源； 如果 TBF信息被填充至分配在第二个载波上的下行 TBF结构中， 则表 示为该 TBF分配了第二个载波上的资源。 比如： 基站为第一个 TBF分配了 第一个载波， 为第二个 TBF分配了第二个载波， 则将第一个 TBF信息填充 至分配在第一个载波上的下行 TBF结构中，将第二个 TBF信息填充至分配 在第二个载波上的下行 TBF结构中， 因此所述指派消息包括分配了第一个 载波上的资源的临时数据块流信息和分配了第二个载波上的资源的临时数 据块流信息； 再比如： 基站为第一个 TBF分配了第一个载波或者第二个载 波， 为第二个 TBF分配了第一个载波和第二个载波， 则将第一个 TBF信息 填充至分配在第一个载波上的下行 TBF结构中或者分配在第二个载波上的 下行 TBF结构中，将第二个 TBF信息填充至分配在两个载波上的下行 TBF 结构中， 因此所述指派消息包括分配了单个载波资源的临时数据块流信息 和分配了两个载波资源的临时数据块流信息。
下面为第一种下行指派消息内容的部分编码示例：
Figure imgf000007_0001
{ 0 I { 1 < Multiple Downlink TBF Assignment CI： < Multiple Downlink TBF Assignment struct > > } * * 0 }
0 I { 1 < Multiple Downlink TBF Assignment C2: < Multiple Downlink TBF Assignment struct > > } * * 0 }。
上述指派消息表示既有分配了两个载波的 TBF, 又有分配了第一个载 波的 TBF, 还有分配了第二个载波的 TBF。
釆用第二种下行指派消息方式的指派消息格式包括： 两个指派的载波 信息、 分配在两个载波资源上的下行 TBF结构以及其他信息。 所述分配在 两个载波资源上的下行 TBF结构包括第一个时隙指派位图以及第二个时隙 指派位图， 才艮据为 TBF所分配的载波资源， 将所述第一个时隙指派位图以 及第二个时隙指派位图设置为有效， 并同时将临时数据块流信息填充至分 配在两个载波资源上的临时数据块流结构中。 如果第一个时隙指派位图以 及第二个时隙指派位图均有效， 表示为该 TBF分配两个载波上的资源； 如 果第一个时隙指派位图有效而第二个时隙指派位图无效， 表示为该 TBF指 派与第一个时隙指派位图对应的载波上的资源； 如果第一个时隙指派位图 无效而第二个时隙指派位图有效， 表示为该 TBF分配与第二个时隙指派位 图对应的载波资源。
下面为第一种下行指派消息内容的部分编码示例：
< Dual Carrier Multiple Downlink TBF Assignment struct > ::=
{ 1
{ 0 I 1 < TIMESLOT— ALLOCATION— CI： bit (8) > }
{ 0 I 1 < TIMESLOT— ALLOCATION— C2： bit (8) > }
{ 1 < Downlink TBF assignment ： < Dual Carrier Downlink TBF assignment struct > > } ** 0
I ** Q
如果在建立与下行数据帧对应的 TBF之前已经存在其他的 TBF, 则还 需要^ ί'爹改原始 TBF的载波配置， 例如： 在建立与下行数据帧对应的 TBF之 前， 如果 BSS与 MS之间已经通过 TBF1进行某些下行数据的传输， 且为 TBF1 分配了单个载波 Carrier-A 的资源， 而为新建的 TBF2 分配了载波 Carrier-B和 Carrier-C的资源， 由于 MS与 BSS之间仅允许存在两个载波， 则需要将所述 TBF1的分配的载波 Carrier-A更改为载波 Carrier-B或者载波 Carrier-C,因此指派消息需要为 TBF指派两个载波 Carrier-B和 Carrier-C的 资源 , 为 TBF1指派载波 Carrier-B或者 Carrier-C的资源。
步骤 204: BSS发送所述下行指派消息给 MS;
步骤 205: MS收到所述下行指派消息后， 根据所述下行指派消息中获 得为各 TBF指派的载波， 并通过指派的载波在对应的临时数据流块上传输 数据， 各 TBF上传送对应的下行数据至 BSS。
通过本发明为移动台指派载波资源方法第一较佳实施例， 可以提高载 波资源指派的效率， 进一步提高了系统峰值数据速率和平均速率。
图 3 为本发明为移动台指派载波资源方法第二较佳实施例的流程图， 本发明为移动台指派载波资源方法第二较佳实施例是在传送上行数据时为 TBF指派载波资源， 具体包括：
步骤 301 : MS向 BSS发送带有 PFI的分组资源请求；
步骤 302: BSS收到所述分组资源请求后， 建立与分组资源请求对应的 一个或多个 TBF, 并为各临时数据块流分配单个载波和 /或两个载波上的资 源；
步骤 303: BSS根据为 TBF指派的载波情况， 构造用于指示各 TBF载 波指派情况的指派消息， 所述指派消息包括分配了单个载波资源的临时数 据块流信息和 /或分配了两个载波资源的临时数据块流信息；
可以釆用两种指派消息构造方式来构造指派消息。
釆用第一种下行指派消息构造方式的指派消息格式包括： 两个指派的 载波信息、 一个或多个两个载波上的上行 TBF结构、 一个或多个分配在第 一个载波上的上行 TBF 结构以及一个或多个分配在第二个载波上的上行 TBF结构。才艮据 TBF所分配到的载波， 将对应的 TBF信息填充至所述分配 在两个载波上的上行 TBF结构、一个分配在第一个载波上的下行 TBF结构、 一个分配在第二个载波上的下行 TBF结构中。如果 TBF信息被填充至分配 在两个载波上的下行 TBF结构中， 则表示为该 TBF分配了两个载波上的资 源； 如果 TBF信息被填充至分配在第一个载波上的下行 TBF结构中， 则表 示为该 TBF分配了第一个载波上的资源； 如果 TBF信息被填充至分配在第 二个载波上的下行 TBF结构中，则表示为该 TBF分配了第二个载波上的资 源。 比如： 基站为第一个 TBF分配了第一个载波， 为第二个 TBF分配了第 二个载波， 则将第一个 TBF信息填充至分配在第一个载波上的上行 TBF结 构中， 将第二个 TBF信息填充至分配在第二个载波上的上行 TBF结构中； 再比如： 基站为 TBF分配了第一个载波和第二个载波， 则将 TBF信息填充 至分配在两个载波上的上行 TBF结构中。
下面为第一种载波上行指派消息内容的部分编码示意图：
< Multiple TBF Uplink Assignment message content > ::=
{ 0 I { 1 < Dual Carrier Multiple Uplink TBF Assignment： < Dual Carrier Multiple Uplink TBF Assignment struct > > } ** 0 }
0 I { 1 < Multiple Uplink TBF Assignment CI： < Multiple Uplink TBF
Figure imgf000010_0001
{ 0 I { 1 < Multiple Uplink TBF Assignment C2: < Multiple Uplink TBF Assignment struct > > } ** 0 }。
上述指派消息可以表示一个或多个 TBF分配了两个载波上的资源， 另 一个或多个 TBF分配了第一个载波上的资源，还有一个或多个 TBF分配了 第二个载波上的资源。
釆用第二种下行指派消息方式的指派消息内容包括： 两个指派的载波 信息、 一个或多个两个载波上的上行 TBF结构以及其他信息。 所述一个或 多个两个载波上的上行 TBF结构包括第一个时隙指派位图以及第二个时隙 指派位图， 所述第一个时隙指派位图以及第二个时隙指派位图有效性均设 置为可选。 如果第一个时隙指派位图以及第二个时隙指派位图均有效， 表 示为 TBF分配了两个载波上的资源； 如果第一个时隙指派位图有效而第二 个时隙指派位图无效， 表示为 TBF分配了与第一个时隙指派位图对应的载 波上的资源； 如果第一个时隙指派位图无效而第二个时隙指派位图有效， 表示为 TBF分配了与第二个时隙指派位图对应的载波上的资源。 因此， 通 过第二种载波上行指派消息， 可以指示 TBF同时分配单个载波和两个载波 的情形。
下面为第二种载波上行指派消息内容的部分编码示意：
< Dual Carrier Multiple Uplink TBF Assignment struct > ::= { 0 I 1 < TIMESLOT— ALLOCATION— CI： bit (8) > }
{ 0 I 1 < TIMESLOT— ALLOCATION— C2： bit (8) > }
{ 1 < Uplink TBF assignment： < Dual Carrier Uplink TBF assignment struct > > } ** 0
I ** Q
如果在建立与分组资源请求对应的 TBF之前已经存在其他的已分配了 载波的 TBF, 则还需要修改原始 TBF的载波配置， 例如： 在建立与分组资 源请求对应的 TBF之前， 如果 MS与 BSS之间已经通过 TBF1进行某些上 行数据的传输， 且为 TBF1分配了单个载波 Carrier-A的资源， 而为新建的 TBF2分配了载波 Carrier-B和 Carrier-C的资源， 由于 MS与 BSS之间仅允 许存在两个载波， 则需要将所述 TBF1的分配的载波 Carrier-A的资源更改 为载波 Carrier-B或者载波 Carrier-C的资源， 因此需要通过指派消息通知移 动台为 TBF2分配两个载波 Carrier-B和 Carrier-C的资源， 为 TBF1分配载 波 Carrier-B或者 Carrier-C的资源。
步骤 304: BSS发送所述载波上行指派消息给 MS;
步骤 305: MS收到所述载波上行指派消息后， 根据所述载波上行指派 消息中获得为各 TBF指派的载波， 并通过指派的载波在对应的临时数据流 本发明实施例所提供的为移动台指派载波资源方法及其系统可以应用 在： 发送分组下行指派 (Packet Downlink Assignment) , 多临时数据块流下行 指派 (Multiple TBF Downlink Assignment) , 分组上行确认和否定确认 (Packet Uplink Ack/Nack) , 分组上行指派 (Packet Uplink Assignment) , 多临时数据 块流上行指派 ( Multiple TBF Uplink Assignment), 分组时隙重配置 ( Packet Timeslot Reconfigure), 多临时数据块流时隙重配置 (Multiple TBF Timeslot Reconfigure), 分组切换命令 (PS Handover Command), 双传输模式切换命令 (DTM Handover Command) , 分组指派（Packet Assignment) , 立即指派 (Immediate Assignment) , 立即指派扩 (Immediate Assignment Extended) , 又 传输模式指派命令 (DTM Assignment Command)等消息的系统指示移动台分 配无线资源的场景中。 通过本发明为移动台指派载波资源方法第二较佳实施例， 可以有效提 高载波资源指派的效率， 进一步提高了系统峰值数据速率和平均速率。
另外， 本发明实施例提供的为移动台指派载波资源的方法及其系统还 可以为移动台指派单个载波和 /或多个（两个以及两个以上)载波上的资源。 所述为移动台指派载波资源系统所包括的移动台与基站， 都具有支持两个 以及两个以上载波的能力。
下面详细描述为移动台指派单个载波和 /或多个（两个以及两个以上)载 波上的资源时， 所述为移动台指派载波资源的方法中指派消息的构成过程。
釆用第一种下行指派消息方式构造的指派消息格式包括： 多个指派的 载波信息、 分配在多个载波上的下行 TBF结构、 以及分配在部分载波上的 下行 TBF结构。 根据 TBF所分配的载波， 将对应的 TBF信息填充至所述 分配在多个载波上的下行 TBF结构、分配在部分载波上的下行 TBF结构中。 如果 TBF信息被填充至分配在多个载波上的下行 TBF结构中，则表示为该 TBF分配了消息指示的所有载波上的资源； 如果 TBF信息被填充至分配在 部分载波上的下行 TBF结构中，则表示为该 TBF分配了对应的部分载波上 的资源。 部分载波使用一个位图来表示使用了哪些载波， 位图的某位置的 信息有效即表示分配了相应的载波资源。 分配部分载波也包括了只分配一 个载波的情形。 比如： 基站为一个移动台分配了三个 TBF, 使用三个载波 上的资源传输数据， 第一个 TBF分配了所有三个载波上的资源， 为第二个 TBF分配了第一个和第二个载波上的资源， 为第三个 TBF分配了第一个和 第三个载波上的资源， 则将第一个 TBF信息填充至分配在多个载波上的下 行 TBF结构中，将第二个 TBF信息填充至携带第一个载波和第二个载波的 位图的相应的部分载波的下行 TBF结构中，将第三个 TBF信息填充至携带 第一个和第三个载波的位图的相应的部分载波的下行 TBF结构中， 因此所 述指派消息包括分配了多个载波上的资源的临时数据块流信息和分配了部 分载波上的资源的临时数据块流信息。
下面为第一种下行指派消息内容的部分编码示例：
< Multiple TBF Multi Carrier Downlink Assignment message content > ::= { 1 < Carrier Information： <Carrier Information struct» } ** 0 { 0 I { 1 < Multi Carrier Multiple Downlink TBF Assignment ： < Multi Carrier Multiple Downlink TBF Assignment struct > > } ** 0 }
{ 0 I { 1 < Part Carrier Multiple Downlink TBF Assignment： < Part Carrier Bitmap> < Multi Carrier Multiple Downlink TBF Assignment struct > > } **
0 }。
釆用第二种下行指派消息方式构造的指派消息与为移动台指派载波资 源方法第一和第二较佳实施例中的原理基本相同， 这里不再赘述。
通过本发明实施例提供的为移动台指派载波资源方法及其系统， 可以 通过一条指派消息为移动台与基站之间通信的一个或多个临时数据块流指 派单个载波和 /或多个载波， 提高了载波资源指派的效率， 进一步提高了系 统峰值数据速率和平均速率。
以上对本发明所提供的一种为移动台指派载波资源方法及其系统行了 以上实施例的说明只是用于帮助理解本发明所揭示的技术方案； 同时， 对 于本领域的一般技术人员， 依据本发明的思想， 在具体实施方式及应用范 围上均会有改变之处， 综上所述， 本说明书内容不应理解为对本发明的限 制。
