一个 TBF可以分配一个或多个 PDCH, 并且一个 PDCH 可以 载多个 TBF。
目前， TBF的 PDCH分配方式为： 1、 接入网侧根据用户设备用户的多时 隙能力确定需要分配的 PDCH数目， 2、 从所有的 PDCH中， 根据 PDCH的复 用度和需要分配的 PDCH数目， 选择一组承载能力较好的、 复用度较低的信 道组分配给 TBF;然后接入网侧将所选择的信道组和指定的时间通过下行信道 指派（ Packet Downlink Assignment )消息发送给用户设备， 用户设备在指定的 时间切换到所指派的信道组接收下行分组业务数据，如果用户设备接收到下行 分组业务数据， 则认为下行 TBF建立成功。 在对现有技术的研究和实践过程中，本发明的发明人发现， 虽然上述 TBF 的 PDCH分配方式能将 TBF均分到各个 PDCH中， 使得各个 PDCH承载的

具体实施方式 下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清 楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明一部分实施例， 而不是 全部的实施例。基于本发明中的实施例， 本领域普通技术人员在没有作出创造 性劳动前提下所获得的所有其他实施例， 都属于本发明保护的范围。 本发明实施例提供一种下行临时块流的信道分配方法，本发明实施例还提 供相应的装置。 以下分别进行详细说明。 请参阅图 1 , 本发明实施例提供下行临时块流的信道分配方法的一个实施 例， 具体流程包括：
101、 当下行分组业务数据到达接入网侧时， 接入网侧获取各个 PDCH上 已承载的每个下行 TBF的緩存数据量和各个 PDCH上已承载的每个下行 TBF与 PDCH的对应关系。
下行 TBF用于在接入网侧和用户设备之间承载分组业务，只有当用户设备 和接入网侧之间需要传输数据的时候， 用户设备和接入网侧才会建立下行 TBF, 下行 TBF建立的流程受到接入网侧的控制。
在本步骤中，当目的地址为某一用户设备的下行分组业务数据到达接入网 侧时， 接入网侧获取各个 PDCH上已承载的每个下行 TBF的緩存数据量和各个 PDCH上已承载的每个下行 TBF与 PDCH的对应关系， 需要说明的是， 若某一 PDCH为空闲状态， 该 PDCH上已承载的每个下行 TBF的緩存数据量为零。
在本文中， 各个 PDCH上已承载的下行 TBF的緩存数据量指的是在接入网 侧收到的、 由核心网下发的、 还没有通过各个 PDCH上已承载的下行 TBF发送 给用户设备的下行分组业务数据的数据量，该下行分组业务数据在未发送给用 户设备之前， 先在接入网侧緩存。 例如， 下行分组业务数据是通过下行分组业 务的协议数据单元（PDU, Protocal Data Unit ) 的形式传输的， 核心网接收到 PDU之后， 会将该 PDU传输到接入网侧， 当该 PDU到达接入网侧时， 在未将该 PDU发送给用户设备之前， 将该 PDU在接入网侧緩存， 该 PDU的数据量就是前 述的各个 PDCH上已承载的下行 TBF的緩存数据量。
在本实施例中， 接入网侧可以由基站收发台 （ BTS , Base Transceiver Station ), 基站控制器（ BSC, Base Station Controller )和分组控制单元（ PCU, Package Control Unit )组成， 在此场景下， 本实施例的步骤可以由基站控制器 来执行。
102、 从各个 PDCH中选择负载量较小的 PDCH作为第一 PDCH。
接入网侧可以按照步骤 101中获取的各个 PDCH上已承载的每个下行 TBF 的緩存数据量和各个 PDCH上已承载的每个下行 TBF与 PDCH的对应关系， 获 取每个 PDCH的负载量， 从各个 PDCH中选择负载量较小的 PDCH作为第一 PDCH。 在本文中， 每个 PDCH的负载量是其承载的所有下行 TBF的緩存数据 量的总和。
在本实施例中， 第一 PDCH可以是在各个 PDCH中， 具有最小负载量的 PDCH, 也可以是在各个 PDCH中， 低于某一阈值的任意一个 PDCH。
需要说明的是， 第一 PDCH是在本实施例中接入网侧为将要建立的 TBF分 配的信道， 并不代表对 PDCH的任何顺序或者标识上的限定。
103、 向用户设备发送携带第一 PDCH的信息的第一指配消息。 当接入网侧选择了第一 PDCH之后， 向用户设备发送携带第一 PDCH的信 息的第一指配消息， 使得用户设备按照第一指配消息在第一 PDCH上接收下行 分组业务数据。 需要说明的是，第一指配消息是用于让用户设备根据第一指配消息在分配 的信道上接收下行分组业务数据，并不代表对指配消息的任何顺序或者标识上 的限定。
指配消息可以是下行信道指派（ Packet Downlink Assignment )消息， 接入 网侧将所分配的 PDCH通过下行信道指派（ Packet Downlink Assignment )消息 发送给用户设备。 通常， 下行分组信道指派消息还会携带指定的时间信息， 用 户设备收到下行分组信道指派消息后，在指定的时间从接入网侧分配的 PDCH 接收下行分组业务数据， 当用户设备开始接收到下行分组业务数据， 下行 TBF 建立成功。 本实施例中， 当下行分组业务数据到达接入网侧时， 接入网侧按照各个 PDCH上已承载的每个下行 TBF的緩存数据量和各个 PDCH上已承载的每个下 行 TBF与分组数据信道 PDCH的对应关系获取每个 PDCH的负载量， 选择负载 量较小的第一 PDCH, 然后向用户设备发送第一指配消息， 第一指配消息携带 第一 PDCH的信息， 用户设备按照第一指配消息在第一 PDCH上接收下行分组 业务数据。本发明实施例提供的技术方案能够在分配信道时，尽量将数据量均 摊到各个 PDCH, 提高 PDCH的资源利用率， 减少高数据量分组业务在 PDCH 上的复用， 提高用户的业务体验。 请参阅图 2, 本发明实施例还提供下行临时块流的信道分配方法的另一个 实施例， 具体如下：
201、 为各个 PDCH上已 7 载的下行 TBF进行信道重配置时， 获取各个 PDCH上已承载的每个下行 TBF的緩存数据量和各个 PDCH上已承载的每个下 行 TBF与 PDCH的对应关系。
在本实施例中， 为了更加充分的利用 PDCH资源， 接入网侧可以为各个 PDCH上已承载的下行 TBF进行信道重配置。 例如， 接入网侧可以在为下行分 组业务数据建立完下行 TBF (即执行完步骤 101~103 )之后， 随即执行为各个 PDCH上已承载的下行 TBF进行信道重配置的操作， 接入网侧也可以在各个 PDCH上已承载的下行 TBF发生负载消耗的时候， 执行为各个 PDCH上已承载 的下行 TBF进行信道重配置的操作。 在本实施例中， 接入网侧重配置的是用于 承载具有较大緩存数据量的下行 TBF的 PDCH。
当为各个 PDCH上已承载的下行 TBF进行信道重配置时， 接入网侧获取各 个 PDCH上已承载的每个下行 TBF的緩存数据量和各个 PDCH上已承载的每个 下行 TBF与 PDCH的对应关系。
202、 获取每个 PDCH的负载量。
接入网侧按照各个 PDCH上已承载的每个下行 TBF的緩存数据量和各个 PDCH上已承载的每个下行 TBF与 PDCH的对应关系， 获取每个 PDCH的负载 量。 203、 获取各个 PDCH相互之间的负载量差， 判断是否存在超过第一门限 值的负载量差， 若是， 则执行步骤 204, 若否， 则执行步骤 205。
接入网侧在所有的 PDCH中，按照各个 PDCH的负载量获取各个 PDCH相互 之间的负载量差， 判断是否存在超过第一门限值的负载量差， 例如， 假设载频 中的 4个信道是 PDCH, 分别为， TS0~TS1 , TS5-TS7, 接入网侧可以判断 TS0 和 TS1、 TS0和 TS5、 TS0和 TS7、 TS1和 TS5、 TS1和 TS7、 TS5和 TS7之间的负 载量差值是否存在至少一个负载量超值超过第一门限值， 通常， 第一门限值可 以根据实际需要进行调试获得， 或根据仿真按照信道业务情况获得。
若在各个 PDCH之间的负载量差中， 存在超过第一门限值的负载量差， 接 入网侧需要为各个 PDCH上已承载的下行 TBF进行信道重配置，在本实施例中， 接入网侧调整的是用于承载具有较大緩存数据量的下行 TBF的信道，接入网侧 执行步骤 204。
若在各个 PDCH之间的负载量差中， 不存在超过第一门限值的负载量差， 接入网侧不需要为各个 PDCH上已承载的下行 TBF进行信道重配置， 接入网侧 执行步骤 205。
204、 选择负载量较小的 PDCH作为第二 PDCH, 向具有较大緩存数据量的 下行 TBF对应的用户设备发送第二指配消息。
当接入网侧需要为各个 PDCH上已承载的下行 TBF进行信道重配置时， 接 入网侧选择负载量较小的 PDCH作为第二 PDCH, 向具有较大緩存数据量的下 行 TBF对应的用户设备发送第二指配消息， 第二指配消息携带第二 PDCH的信 息和具有较大緩存数据量的下行 TBF的信息，使得用户设备获知接入网侧将用 于承载具有较大緩存数据量的下行 TBF的信道调整为第二 PDCH。
在本实施例中， 第二 PDCH可以是在各个 PDCH中， 具有最小负载量的 PDCH, 也可以是在各个 PDCH中， 低于某一阈值的任意一个 PDCH; 具有较大 緩存数据量的下行 TBF可以是具有最大緩存数据量的下行 TBF , 也可以是高于 某一阈值的任意一个下行 TBF。
需要说明的是， 第二 PDCH是在本实施例中接入网侧为用于承载具有较大 緩存数据量的下行 TBF重分配的信道， 并不代表对 PDCH的任何顺序或者标识 上的限定。第二指配消息是用于让用户设备获知为用于承载具有较大緩存数据 量的下行 TBF重分配的信道，并不代表对指配消息的任何顺序或者标识上的限 定。
205、 保持各个 PDCH上已承载的下行 TBF的信道配置。
当接入网侧不需要为各个 PDCH上已承载的下行 TBF进行信道重配置时， 接入网侧保持各个 PDCH上已承载的下行 TBF的信道配置。
本实施例中， 在各个 PDCH相互之间的负载量差中， 当存在超过第一门限 值的负载量差时， 接入网侧需要为各个 PDCH上已承载的下行 TBF进行信道重 配置， 接入网侧将负载量较小的 PDCH分配给用于承载具有较大緩存数据量的 下行 TBF, 本发明实施例提供的技术方案能够对各个 PDCH上已承载的下行 TBF的信道配置进行调整， 基本保持所有数据量均摊到各个 PDCH, 充分利用 PDCH资源。 请参阅图 3, 为下行临时块流的信道分配方法的另一个实施例， 在本实施 例中， 接入网侧可以为一个 TBF分配多个 PDCH, 具体可以包括：
301、 当下行分组业务数据到达接入网侧时， 接入网侧在按照各个 PDCH 之间的排列关系， 获取能形成较大连续排列关系的 PDCH的个数；
GSM采用分组交换技术， 载频提供的信道既可以被话音占用， 也可以被 分组业务数据占用， 但是话音和分组业务数据不能同时占用相同的信道， 当 GSM载频提供的信道没有被话音占用时， 信道就可以以分组形式传送数据， 这些信道即为 PDCH。 一个载频可以提供 8个信道， 分别用信道号 （TS, Time Slot ) 0~7来表示， 按照信道号的连续关系 PDCH在 8个信道中会有不同的排列关系， 例如， TS0和 TS1没有被话音占用时， 信道可以以分组形式传送数据， TS0和 TS1为 PDCH, TSO和 TSl的信道号是连续的， TS0和 TS1之间的排列关系为连续排列关系， 再 例如， TS1被话音占用， TS0和 TS2没有被话音占用时， 信道可以以分组形式传 送数据， TS0和 TS2为 PDCH, TSO和 TS2的信道号是间隔的， TS0和 TS2之间的 排列关系为间隔排列关系。 在本步骤中， 当下行分组业务数据到达接入网侧时， 接入网侧按照各个 PDCH之间的排列关系， 获取能形成较大连续排列关系的 PDCH的个数， 例如： TSO和 TS4~TS7这五个信道是 PDCH,能形成较大连续排列关系的 PDCH的个数 为 4, 这个较大连续排列关系是由 TS4~TS7形成的， 即由较多信道号连续的 PDCH形成的连续排列关系。
在本实施例中， 能形成较大连续排列关系的 PDCH的个数可以是能形成最 大连续排列关系的 PDCH的个数， 也可以是能形成高于某一界限值的连续排列 关系的 PDCH的个数。
302、 判断是否大于由用户设备的多时隙能力所确定的能为下行 TBF指配 的 PDCH数目； 若是， 执行步骤 303, 若否， 执行步骤 304;
当一个 TBF分配多个 PDCH时， 可以增加下行分组业务数据的发送速率， 在建立下行 TBF时， 下行 TBF期望能够尽可能的分配到更多的 PDCH, 但是一 个下行 TBF分配的多个 PDCH必须是连续的。
在本步骤中， 接入网侧在所有的 PDCH中， 判断能形成较大连续排列关系 的 PDCH的个数是否大于由用户设备的多时隙能力所确定的能为下行 TBF指配 的 PDCH数目， 假设用户设备是手机， 由手机的多时隙能力所确定的能为下行 TBF指配的 PDCH数目为 4。
若是， 则说明在所有的 PDCH中， 能形成较大连续排列关系的 PDCH的个 数大于由用户设备的多时隙能力所确定的能为下行 TBF指配的 PDCH数目， 此 时一个下行 TBF所能分配的 PDCH数目为由用户设备的多时隙能力所确定的能 为下行 TBF指配的 PDCH数目， 接入网侧执行步骤 303; 若否， 则说明能形成较大连续排列关系的 PDCH的个数小于或者等于由用 户设备的多时隙能力所确定的能为下行 TBF指配的 PDCH数目， 此时一个下行 TBF所能分配的 PDCH数目为能形成较大连续排列关系的 PDCH的个数， 接入 网侧执行步骤 304。
303、 按照由用户设备的多时隙能力所确定的能为下行 TBF指配的 PDCH 数目， 将各个 PDCH组合成若干个不相同的信道组；
假设载频中的 8个信道都是 PDCH, 用户设备 (以手机为例） 的多时隙能 力所确定的能为下行 TBF指配的 PDCH数目为 4, 在所有 PDCH中可以组合 5个 信道组， 分别是 TS0~ TS3 , TS1- TS4, TS2~ TS5 TS3- TS6, TS4~ TS7, 每个 信道组中 PDCH之间是连续排列关系。
304、 按照能形成较大连续排列关系的 PDCH的个数， 将各个 PDCH组合成 若干个不相同的信道组；
假设载频中的 4个信道是 PDCH, 分别为， TS0~TS1 , TS5-TS7, 能形成较 大连续排列关系的 PDCH的个数为 3 , 用户设备（以手机为例） 的多时隙能力 所确定的能为下行 TBF指配的 PDCH数目为 4, 在所有 PDCH中可以组合一个信 道组， 是 TS5~TS7。
305、 获取每个信道组的负载量， 从每个信道组中选择负载量较小信道组 作为第一信道组。
当接入网侧组合完信道组后， 获取各个 PDCH上承载的每个下行 TBF的緩 存数据量和各个 PDCH上承载的每个下行 TBF与 PDCH的对应关系， 按照各个 PDCH上已承载的每个下行 TBF的緩存数据量和各个 PDCH上已承载的每个下 行 TBF与 PDCH的对应关系获取每个组合而成的信道组的负载量， 从每个信道 组中选择负载量较小信道组作为第一信道组。
在本实施例中， 负载量较小的第一信道组可以是负载量最小的第一信道 组， 也可以是低于某一阈值的任意一个信道组。
需要说明的是， 第一信道组是在本实施例中接入网侧为将要建立的下行 TBF分配的信道组， 并不代表对信道组的任何顺序或者标识上的限定。
306、 向用户设备发送第三指配消息。
接入网侧向用户设备发送第三指配消息，第三指配消息携带第一信道组的 信息，使得用户设备按照第三指配消息切换到第一信道组接收下行分组业务数 据。 第三指配消息是用于让用户设备获知为将要建立的下行 TBF分配的信道 组， 并不代表对指配消息的任何顺序或者标识上的限定。
本实施例中， 接入网侧按照各个 PDCH之间的排列关系， 获取能形成较大 连续排列关系的 PDCH的个数， 按照能形成较大连续排列关系的 PDCH的个数 与由用户设备的多时隙能力所确定的能为下行 TBF指配的 PDCH数目的大小关 系， 在所有 PDCH中组合若干个不相同的由连续的 PDCH组成的信道组， 将负 载量较小的信道组分配为将要建立的下行 TBF的信道组，本发明实施例提供的 技术方案不仅能够在为下行 TBF分配信道时，尽量将数据量均摊到各个 PDCH, 提高 PDCH的资源利用率， 减少高数据量分组业务在 PDCH上的复用， 提高用 户的业务体验， 而且接入网侧为下行 TBF分配的是信道组， 能够增加下行分组 业务数据的发送速率。 请参阅图 4, 本发明实施例提供下行临时块流的信道分配方法的另一个实 施例， 本实施例描述的是接入网侧对各个 PDCH上己承载的下行 TBF进行信道 重调整，使得网络的 PDCH资源更加得到充分利用，本实施例的具体流程包括：
401、 为各个 PDCH上已 7 载的下行 TBF进行信道重配置时， 获取各个 PDCH上已承载每个下行 TBF的緩存数据量和各个 PDCH上已承载的每个下行 TBF与 PDCH的对应关系， 获取每个 PDCH的负载量；
在本实施例中， 为了更加充分的利用 PDCH资源， 接入网侧可以为各个 PDCH上已承载的下行 TBF进行信道重配置。 例如， 接入网侧可以在为下行分 组业务数据建立完下行 TBF (即执行完步骤 301~306 )之后， 随即执行为各个 PDCH上已承载的下行 TBF进行信道重配置的操作， 接入网侧也可以在各个 PDCH上已承载的下行 TBF发生负载消耗的时候， 执行为各个 PDCH上已承载 的下行 TBF进行信道重配置的操作。接入网侧调整的是用于承载具有较大緩存 数据量的下行 TBF的 PDCH, 在本实施例中， 具有较大緩存数据量的下行 TBF 可以是具有最大緩存数据量的下行 TBF,也可以是高于某一阈值的任意一个下 行 TBF。 当为各个 PDCH上已承载的下行 TBF进行信道重配置时， 接入网侧获取各 个 PDCH上已承载的每个下行 TBF的緩存数据量和各个 PDCH上已承载的每个 下行 TBF与 PDCH的对应关系。
接入网侧按照各个 PDCH上已承载的每个下行 TBF的緩存数据量和各个 PDCH上已承载的每个下行 TBF与 PDCH的对应关系获取每个 PDCH的负载量；
402、 按照各个 PDCH的负载量获取各个 PDCH相互之间的负载量差， 判断 是否存在超过第二门限值的负载量差， 若是， 则执行步骤 403~407； 若否， 则 执行步骤 409;
通常， 第二门限值可以根据实际需要进行调试获得， 或根据仿真按照信道 业务情况获得。
403、 按照各个 PDCH之间的排列关系， 获取能形成较大连续排列关系的 PDCH的个数；
404-406, 同步骤 302~304, 此处不再赞述。
407、 按照每个 PDCH的负载量获取每个信道组的负载量， 从信道组中选 择负载量较小信道组作为第二信道组；
接入网侧在完成信道组的组合之后， 按照步骤 401中获取的每个 PDCH的 负载量获取每个信道组的负载量，从信道组中选择负载量较小信道组作为第二 信道组。
在本实施例中， 负载量较小的第二信道组可以是负载量最小的第二信道 组， 也可以是低于某一阈值的任意一个信道组。
需要说明的是，第二信道组是在本实施例中接入网侧为已建立的下行 TBF 重分配的信道组， 并不代表对信道组的任何顺序或者标识上的限定。
408、 向具有较大緩存数据量的下行 TBF对应的用户设备发送第四指配消 接入网侧向用户设备发送第四指配消息，该用户设备是通过具有较大緩存 数据量的下行 TBF传输下行分组业务数据。第四指配消息携带第二信道组的信 息和具有较大緩存数据量的下行 TBF的信息，使得用户设备获知接入网侧将用 于承载具有较大緩存数据量的下行 TBF的信道调整为第二信道组。
第四指配消息是用于让用户设备获知为已建立的下行 TBF重分配的信道 组， 并不代表对指配消息的任何顺序或者标识上的限定。
409、 保持各个 PDCH上已承载的下行 TBF的信道配置。
当接入网侧不需要为各个 PDCH上已承载的下行 TBF进行信道重配置时， 接入网侧保持各个 PDCH上已承载的下行 TBF的信道配置。
本实施例中， 在各个 PDCH相互之间的负载量差中， 当存在超过第二门限 值的负载量差时， 接入网侧需要为各个 PDCH上已承载的下行 TBF进行信道重 配置，接入网侧在每个信道组中，选取负载量较小的第二信道组设置为用于承 载具有较大緩存数据量的下行 TBF重分配的信道，本发明实施例提供的技术方 案能够对各个 PDCH已承载的下行 TBF的信道进行调整， 基本保持所有数据量 均摊到各个 PDCH, 充分利用 PDCH资源。 为了便于理解， 下面将以两个具体的应用场景为例，对本发明实施例中下 行临时块流的信道分配方法进行阐述。这两个应用场景可以参考步骤 301~306、 以及步骤 401~409。
第一个应用场景是： 当下行分组业务数据到达接入网侧时，接入网侧对将 要建立的下行 TBF分配信道组， 具体如下：
载频的 8个信道 TS0~TS7都是 PDCH, 接入网侧获取各个 PDCH上已承载的 每个下行 TBF的緩存数据量和各个 PDCH上已承载的每个下行 TBF和 PDCH的 对应关系， 按照各个 PDCH上已承载的每个下行 TBF的緩存数据量和各个 PDCH上已承载的每个下行 TBF和 PDCH的对应关系获取各个 PDCH的负载量， 具体为： TS0~ TS3承载两个下行 TBF,分别是下行 TBF—和下行 TBF二， TS4- TS7承载两个下行 TBF, 分别是下行 TBF三和下行 TBF四， 下行 TBF—的緩存数 据量为 1200Kbytes,下行 TBF二的緩存数据量为 3600Kbytes, TS0~ TS3中各个 PDCH的负载量为： 1200Kbytes/4+3600Kbytes/4=1200Kbytes , 下行 TBF三的緩 存数据量为 400Kbytes,下行 TBF四的緩存数据量为 800Kbytes, TS4~ TS7中各 个 PDCH的负载量为： 400Kbytes/4+800Kbytes/4=300Kbytes。
接入网侧按照各个 PDCH之间的排列关系， 获取能形成较大连续排列关系 的 PDCH的个数为 8, 用户设备为手机， 用户设备的多时隙能力所确定的能为 下行 TBF指配的 PDCH数目为 4, 由于能形成较大连续排列关系的 PDCH的个数 大于用户设备的多时隙能力所确定的能为下行 TBF指配的 PDCH数目， 接入网 侧按照用户设备的多时隙能力所确定的能为下行 TBF指配的 PDCH数目在所有 PDCH中组合若干个不相同的信道组， 每个信道组中 PDCH是连续的， 可以在 PDCH中组合成 5个信道组，分别是 TS0~ TS3, TS1~ TS4, TS2~ TS5 , TS3~ TS6, TS4~ TS7。
当接入网侧获得这 5个的信道组后， 按照每个 PDCH的负载量， 获取信道 JLTSO- TS3, TS1- TS4, TS2~ TS5 , TS3- TS6, TS4~ TS7的负载量， 分另' J为 4800 Kbytes, 3900 Kbytes, 3000 Kbytes, 2100 Kbytes, 1200 Kbytes, 选取负 载量较小的信道组： TS4~ TS7,接入网侧向手机发送下行信道指派信息，使得 手机在信道组 TS4~ TS7接收下行分组业务数据。
接入网侧按照各个 PDCH之间的排列关系， 获取能形成较大连续排列关系 的 PDCH的个数， 按照能形成较大连续排列关系的 PDCH的个数与由用户设备 的多时隙能力所确定的能为下行 TBF指配的 PDCH数目的大小关系， 在所有 PDCH中组合若干个不相同的由连续的 PDCH组成的信道组， 将负载量较小的 信道组分配为将要建立的下行 TBF的信道组， 因此不仅能够在为下行 TBF分配 信道时， 尽量将数据量均摊到各个 PDCH, 提高 PDCH的资源利用率， 减少高 数据量分组业务在 PDCH上的复用， 提高用户的业务体验， 而且接入网侧为下 行 TBF分配的是信道组， 能够增加下行分组业务数据的发送速率。 第二个应用场景是： 为了能够使得网络的 PDCH资源得到充分利用， 接入 网侧对各个 PDCH上己承载的下行 TBF进行信道重调整。
载频的 8个信道 TS0~TS7都是 PDCH, 接入网侧获取各个 PDCH上已承载的 下行 TBF的緩存数据量和各个 PDCH上已承载的每个下行 TBF和 PDCH的对应 关系，具体为： TS0~ TS3承载三个下行 TBF,分另' J是下行 TBF五和 TBF六和 TBF 七， TS4~ TS7承载两个下行 TBF, 分别是下行 TBF八和下行 TBF九， 下行 TBF 五的緩存数据量为 3600Kbytes, 下行 TBF六的緩存数据量为 1200Kbytes, 下行 TBF七的緩存数据量为 4000Kbytes, 下行 TBF八的緩存数据量为 800Kbytes, 下 行 TBF九的緩存数据量为 400Kbytes。
按照各个 PDCH上已承载的每个下行 TBF的緩存数据量和各个 PDCH上已 承载的每个下行 TBF与 PDCH的对应关系获取各个 PDCH的负载量， 具体为：
TS0~TS3之间的各个 PDCH的负载量为：
1200Kbytes/4+3600Kbytes/4+4000Kbytes/4=2200Kbytes ,
TS4~TS7之间的各个 PDCH的负载量为：
400Kbytes/4+800Kbytes/4=300Kbytes,
设定门限值为 1500Kbytes , 在所有的 PDCH中， 按照各个 PDCH的负载量 接入网侧获取各个 PDCH之间负载量差， 在各个 PDCH之间的负载量差中存在 超过门限值的负载量差。
