在本实施例中, 所述配置所述移动终端的下行链路质量测量报告携带方 式包括: 通过指配消息或者重配置消息配置所述移动终端的下行链路质量测 量报告携带方式。 所述指配消息或者重配置消息配置可以是: 分组上行指配 消息 PACKET UPLINK ASSIGMENT、 立即指配消息 IMMEDIATE ASSIGNMENT, 分组时隙重指配消息 PACKET TIMESLOT RECONFIGUR。
具体的, 下行链路质量测量报告携带方式以字段域:
{0 I 1 基于数据携带的测量报告的激活指示字段 (Indication of PMR Activated ) : bit ( 1 ) }
的形式新增于指配消息或者重配置消息中, 具体的, 新增于指配消息或者重 配置消息最后, 作为指配消息或者重配置消息的末字节;
其中, 基于数据携带的测量报告的激活指示字段用于表示是否激活移动 终端的基于上行 RLC数据块的携带方式。
在本实施例中,基于数据携带的测量报告的激活指示字段为 1 ,表示激活 所述移动终端基于上行 RLC数据块的携带方式, 其中, 所述基于上行 RLC 数据块的携带方式为将所述下行链路质量测量报告携带在上行 RLC数据块中 的方式; 基于数据携带的测量报告的激活指示字段为 0,表示未激活所述移动 终端基于上行 RLC数据块的携带方式(尽管 MS可能支持分组下行实时功控), 下行链路质量测量报告携带方式为基于上行 RLC/MAC控制消息携带方式。
702, 移动终端接收基站控制设备发送的指配消息或者重配置消息, 根据 所述指配消息或者重配置消息中携带的下行链路质量测量报告携带方式, 确 定移动终端发送下行链路质量测量报告的携带方式。
703 , 在需要轮询下行链路测量报告的时刻, 如果下行链路质量测量报告 携带方式指配为基于上行 RLC/MAC控制消息携带方式, BSC请求该移动终 端将所述下行链路测量报告携带在相关的上行 RLC/MAC控制消息中。
在本实施例中, 所述请求该移动终端将所述下行链路测量报告携带在上 行 RLC数据块中, 具体实现方式为:
发送下行 RLC/MAC无线块给所述移动终端, 所述下行 RLC/MAC无线 块中携带用于指示移动终端将下行链路测量报告携带在上行 RLC数据块中的 指示信令。
具体的, 将所述指示信令携带在下行 RLC/MAC无线块头中的功率衰减 ( PR )字段中, 以请求该移动终端将所述下行链路测量报告携带在上行 RLC 数据块中。 其中, 由于 PR字段值中的 11值是预留值, 此处可以通过将 PR 字段值置 11来实现移动终端侧将下行链路质量测量报告携带在上行 RLC数据 块中的指示, 当然, PR字段值得配置数值并不限于上述的一种。
值得说明的是, 基于数据携带的测量报告未被激活的情况下, 下行 RLC/MAC无线块头中的功率衰减 PR字段与现有相同, 此处不再赘述, 但是 基于数据携带的测量报告被激活的情况下, 下行 RLC/MAC无线块头中的功 率衰减 PR字段的定义也相应的进行修改, 如表 3所示, 具体的:
原 PR字段的比特值 11为预留值, 在本实施例中该值用于基站控制设备 指示移动终端在上行 RLC数据块中携带下行链路质量测量报告信息。 PR字 段的其他比特值 00〜10, 除了表示现有含义外, 还表示网络侧不指示 MS在上 行 RLC数据块中携带下行链路质量测量报告信息。
表 3: PMR激活模式下的 PR字段定义
Figure imgf000016_0001
综上所述, 如果该移动终端的 PMR被激活, 则将当前下行 RLC/MAC无 线块头中的 PR字段值置 11 ,那么该移动终端收到 PR值为 11的下行 RLC/MAC 无线块后, 如果移动终端这时存在上行数据, 则在下一个无线块周期内发送 上行 RLC/MAC无线块, 在相应 RLC数据块中携带下行链路质量测量报告; 如果 MS 这时不存在上行数据, 则在下一个无线块周期内发送相关的上行 RLC/MAC控制消息 , 如( EGPRS ) PACKET DOWNLINK ACK/NACK消息。
值得说明的是, 在基站控制设备确定了需要发送下行链路质量测量报告 置为该移动终端的 USF, 以使得该移动终端识别出所述下行 RLC/MAC无线 块。
可以理解的是, 除了在下行 RLC/MAC无线块中携带用于指示移动终端 将下行链路测量报告携带在上行 RLC数据块中的指示信令之外, 还可以通过 其他的现有消息携带该指示信令, 或者也可以通过专门的消息携带该指示信 令, 本实施例对此不做限定。 对应于上述方法, 如图 8 ( a )所示, 本发明另一实施例还提供一种获取 下行链路测量报告的装置, 包括:

进一步的, 为了区分下行数据块与下行空数据控制块的发射功率, 如图
10所示, 本发明实施例提供的差异化的分组下行功控的方法, 可以由基站控 制设备完成, 该方法可以包括:
1001 , 接收移动终端发送的下行链路质量测量报告。
1002, 根据所述下行链路测量报告和当前编码方式计算得到下行数据块 对应的第一下行功控参数。
1003 , 根据所述下行链路测量报告和 CS-1编码方式计算得到携带有上行 状态标识(USF ) 的下行空数据控制块对应的第二下行功控参数。
1004, 将所述第一功控参数、 第二功控参数以及预先设置的的功率衰减 值发送给基站, 其中, 所述预先设置的功率衰减值用于控制不携带 USF的下 行空数据控制块的功控。
在决定调整基站侧下行分组数据信道 PDCH的发射功率时, 基于下行链 路质量测量报告, 所述基站控制设备可以对下行数据块和下行空数据控制块 ( PACKET DOWNLINK DUMMY CONTROL BLOCK) 分别釆用不同的功控 机制。
对应于上述方法, 如图 11所示, 本发明实施例还提供一种差异化的分组 下行功控的设备, 包括:
第四接收单元 111 , 用于接收移动终端发送的下行链路质量测量报告; 第一计算单元 112,用于根据所述下行链路测量报告和当前编码方式计算 得到下行数据块对应的第一下行功控参数;
第二计算单元 113 , 用于根据所述下行链路测量报告和 CS-1编码方式计 算得到携带有上行状态标识 ( USF )的下行空数据控制块对应的第二下行功控 参数;

进一步的, 为了避免小数据量业务的功控难以启动甚至失效的问题, 如 图 12所示, 本发明实施例提供的初始的分组下行功控的方法, 可以由基站控 制设备完成, 该方法, 可以包括:
1201 , 緩存下行功控参数, 并建立所述下行功控参数与移动终端对应的 临时逻辑链路标识 TLLI的关联。
具体的, BSC根据分组下行闭环功控算法, 判定出需要对 BTS发射功率 进行调整时, 将最新计算出来的功率衰减参数 PR緩存下来, 并与 TLLI建立 关联。 功控参数 PR緩存之后, 后续一旦决定需要对该 MS的下行 RLC/MAC 无线块的发射功率再进行调整时, BSC需要更新被緩存的功率衰减参数 PR。 被緩存的 PR作为该 MS下次分组接入后的下行 RLC/MAC无线块发射功率的 初始衰减值。
值得说明的是, 功率衰减参数 PR还包括有效时间期, 緩存 PR时, 需要 设定合适的有效时间期, 一个合适大小的有效时间期反映下行链路质量在这 段期间内出现大的波动的概率较小。 只有在有效时间期内, PR才有效, 否则 无效。
1202, 在该移动终端下次发起分组接入时, 根据 TLLI获取已緩存的下行 功控参数。
在本实施例中, 所述步骤 1202, 包括:
当 MS发起一阶段分组接入时, BSC—旦从上行 RLC/MAC数据块中获 取到 TLLI, 就可以根据 TLLI获取到已緩存的 PR ( PR为相对于 P0的功率衰 减值, P0为相对于广播控制信道 BCCH发射功率的初始衰减值)。如果 PR有 效, BSC通过 Abis接口将 P0和 PR传给 BTS, BTS基于 P0和 PR调整 MS 的下行 RLC/MAC无线块的发射功率。 如果在上行 RLC/MAC无线块中携带 了下行链路质量测量报告域, 则 BSC基于已緩存的 PR和下行链路质量测量 报告执行分组下行闭环功控。
当 MS 发起二阶段分组接入时, BSC 从控制消息, 如分组资源请求 ( PACKET RESOURCE REQUEST )消息 , 中获取到 TLLI和下行链路质量测 量报告, 根据 TLLI获取到已緩存的 PR, BSC基于已緩存的 PR和下行链路 质量测量报告执行分组下行闭环功控。
1203 , 如果所述下行功控参数在预先设置的有效时间期内, 将所述下行 功控参数作为下行 RLC/MAC无线块发射功率的初始衰减值发送给基站。
对应于上述方法, 如图 13所示, 本发明实施例还提供一种初始的分组下 行功控的设备, 包括:
緩存建立单元 1301 , 用于緩存下行功控参数, 并建立所述下行功控参数 与移动终端对应的临时逻辑链路标识 TLLI的关联。

第三发送单元 1303 , 用于如果所述下行功控参数在预先设置的有效时间 期内, 将所述下行功控参数作为下行 RLC/MAC无线块发射功率的初始衰减 值发送给基站。
本发明实施例提供的初始的分组下行功控的方法及装置, 通过釆用上述 的下行功控参数緩存机制, 来解决小数据量业务在分组接入后下行闭环功控 无法启动的问题, 从而提升分组下行闭环功控的增益。

本领域普通技术人员可以理解实现上述实施例方法中的全部或部分步骤 是可以通过程序来指令相关的硬件完成, 所述的程序可以存储于一计算机可 读存储介质中, 如 ROM/RAM、 磁碟或光盘等。
