上行功率检测方法、 装置和基站设备 本申请要求于 2011 年 02 月 23 日提交中国专利局、 申请号为 201110044821.1、 发明名称为"上行功率检测方法、 装置和基站设备"的中国 专利申请的优先权， 其全部内容通过引用结合在本申请中。 技术领域 本发明涉及无线通讯技术领域， 具体涉及一种上行功率检测方法、 装 置和基站设备。
背景技术 在网络覆盖受限时， 基站会触发小区切换。 现有的小区切换都是由下 行信号质量来触发， 即当下行信号质量低于某一门限值时， 触发终端（User Equipment, 以下简称为： UE )进行小区切换。 而在网络规划中， 存在上下 行链路功率不平衡的现象， 由此可能会出现上行覆盖先于下行覆盖受限的 情况， 即在下行覆盖还未受限时， 上行覆盖已经受限。 尤其在上行存在干 扰的场景下， UE的上行发射功率更有可能先于下行受限， 由此导致上行覆 盖先于下行覆盖受限。 若 UE的上行发射功率受限， 则较易发生掉话。
现有技术的小区切换方式中存在的问题是： 由下行信号质量来触发切 换， 无法准确表征上行信号受限的情况， 当上行覆盖先于下行覆盖受限时， 由于此时下行信号质量还未到达触发切换的门限值， 所以不会触发切换， 由此导致 UE容易发生掉话。 由此， 需要提供一种上行功率是否受限的检测 方法， 从而使得检测到上行功率受限时， 可以触发切换。

附图说明 图 1所示为本发明一实施例提供的上行功率检测方法的流程图； 图 2为本发明另一实施例提供的上行功率检测方法的流程图； 图 3为本发明一实施例提供的上行功率检测装置的示意图； 图 4为本发明另一实施例提供的上行功率检测装置的示意图。
具体实施方式 为使本发明的目的、 技术方案、 及优点更加清楚明白， 下面结合附图 并举实施例， 对本发明提供的技术方案进一步详细描述。
图 1为本发明一实施例提供的上行功率检测方法的流程图， 如图 1所 示， 该方法包括：
步骤 101、 检测终端发送的上行数据包的调制编码方式和初始误块率。 对于某 UE发送的上行数据包；基站设备可以检测接收到的上行数据包 的调制编码方式（ Modulation and Coding Scheme , 以下简称为： MCS )和 上行数据包的初始误块率（ Initial Block Error Rate , 以下简称为： IBLER ) 。 需要说明的是， 在 GSM 系统中， 基站设备可以为基站收发信台 （Base Transceiver Station, BTS ) , 在 WCDMA ( Wideband Code Division Multiple Access, 宽带码分多址）和 TD-SCDMA ( Time Division- Synchronous Code Division Multiple Access, 时分同步码分多址） 系统中， 基站设备可以为 NodeB; 在 LTE系统中， 基站设备可以为演进基站（ eNodeB ) 。
其中， 检测终端发送的上行数据包的调制编码方式和初始误块率的方 式可以有多种， 例如可以参考现有技术。
步骤 102、根据检测到的终端发送的上行数据包的调制编码方式的阶数 与第一门限值的关系， 以及检测到的终端发送的上行数据包的初始误块率 与第二门限值的关系， 判断该终端的上行功率是否受限。
基站设备可以根据检测到的该终端发送的上行数据包的 MCS和 IBLER 来判断该终端的上行功率是否受限。 例如： 当基站设备检测到该终端发送 的预定数量的上行数据包的 MCS的阶数小于或等于一预设的门限值 A (即 第一门限值） 时， 基站设备判断 IBLER是否大于另一预设的门限值 B (即 第二门限值） ， 若 IBLER大于门限值 Β, 则基站设备可以判断出该终端的 上行功率受限。
本发明实施例中， 可以由基站设备检测 UE发送的上行数据包的 MCS 和 IBLER, 并可以根据检测到的 MCS和 IBLER来判断该 UE的上行功率 是否受限， 从而能够比较准确地表征 UE的上行信号受限的情况。
图 2 为本发明另一实施例提供的上行功率检测方法的流程图， 如图 2 所示， 该方法可以包括：
步骤 201、 基站设备检测 UE发送的上行数据包的 MCS。
本步骤中， 基站设备对 UE进行 MCS检测。 而检测 MCS的过程可以 为： 基站设备获取该 UE发送的每个上行数据包的 MCS, 并将获取的 MCS 与一门限值， 例如第一门限值， 进行比较。
步骤 202、 若第一预定数量的该 UE发送的上行数据包的 MCS的阶数 小于第一门限值， 且确定出该 UE发送的上行数据包的 IBLER大于第二门 限值， 则判断该 UE的上行功率受限； 其中 MCS的阶数小于第一门限值的 第一预定数量的上行数据包是连续的。
若基站设备检测到该 UE发送的连续的 N1个上行数据包的 MCS的阶 数小于一预设的第一门限值，则基站设备可以对该 UE发送的上行数据包的 IBLER进行判断，例如基站设备可以启动该 UE发送的上行数据包的 IBLER 统计， 即开始统计该 UE发送的上行数据包的 IBLER。 其中， N1为第一预 定数量， N1是可配置的， 而第一门限值例如可以为 1-28, 具体可以根据需 要设置。
需要说明的是， 基站设备在统计连续的、 该 UE发送的 MCS的阶数小 于第一门限值的上行数据包的个数时， 可以对连续的两个上行数据包的间 隔时间不做要求， 也可以对连续的两个上行数据包的间隔时间进行限制； 对间隔时间进行限制的情况例如可以为： 若连续的两个上行数据包的间隔 时间大于预设的一门限值， 例如第五门限值， 则终止本次的统计， 重新开 始下一次的统计， 也就是说， 本步骤中， 当终端发送的上行数据包的连续 两个数据包的时间间隔小于或者等于预设的一门限值时， 可以认为统计有 效。
若基站设备没有检测到该 UE发送的连续的 N1个上行数据包的 MCS 的阶数小于预设的第一门限值， 则说明上行链路稳定， 可以不进行后续的 IBLER统计 , 此时可以继续检测该 UE发送的上行数据包的 MCS。
具体的， 基站设备检测 UE发送的上行数据包的 IBLER的方式可以如 下：
第一种方式：检测在第一时间周期内接收到的 UE发送的上行数据包的 IBLER; 第一时间周期例如为一预设的时间周期 T1；
例如可以为： 设置 IBLER的统计周期为第一时间周期 T1 ,基站设备根 据公式 1统计该周期 T1内接收到的该 UE发送的所有上行数据包的 IBLER; 其中，
八 _v Tr>j CntCorrect
公式 1为： IBler = ；
CntCorrect + Cntlncorrect
CntCorrect 表示在一个统计周期内基站设备解调的正确块数， Cntlncorrect表示在一个统计周期内基站设备解调错误的块数。
第二种方式： 检测第二预定数量的该 UE发送的上行数据包的 IBLER, 其中， 第二预定数量的上行数据包是连续的； 第二预定数量为一预设的统 计数量；
例如可以为： 设置 IBLER的统计数量为 N2; 当启动检测该 UE发送的 上行数据包的 IBLER时， 基站设备开始统计解调正确和解调错误的块数， 当统计的总块数为 N2个时，可以根据公式 1统计这些上行数据包的 IBLER。 该方式中， CntCorrect表示在一个预定的统计数量（N2 ) 中基站设备解调 的正确块数， Cntlncorrect表示在该预定统计数量中基站设备解调错误的块 数。 第三种方式： 若在第二时间周期内，接收到该 UE发送的上行数据包的 数量大于或等于第三门限值， 则检测在该第二时间周期内接收到的该 UE 发送的上行数据包的初始误块率；
该方式例如可以为：统计在第二时间周期内接收到的该 UE发送的上行 数据包的 IBLER, 并统计在该第二时间周期内接收到的该 UE发送的上行 数据包的数量，若在第二时间周期内，接收到的该 UE发送的上行数据包的 数量大于或等于第三门限值， 则认为统计的 IBLER有效， 将统计的 IBLER 与第二门限值进行比较； 若在第二时间周期内，接收到的该 UE发送的上行 数据包的数量小于第三门限值， 则可以认为统计的 IBLER无效， 不将统计 的 IBLER与第二门限值进行比较， 那么可以重新统计下一个时间周期内的 IBLER, 由此循环， 直至一个时间周期内接收到的该 UE发送的上行数据包 的数量大于或等于第三门限值， 将统计的 IBLER与第二门限值进行比较。 其中， 第二时间周期为一预设的时间周期， 可以与前述的第一时间周期相 等， 也可以与第一时间周期不等。
需要说明的是， 该方式中， 当在周期 T2内接收到的该 UE发送的上行 数据包的数量足够多时， 使用统计的周期 T2 内的 IBLER作为检测到的 IBLER, 由此可以提高在周期 T2 内检测 IBLER的准确性， 进而使得由该 IBLER判断的上行功率是否受限的结果也更加准确。
基站设备检测到 IBLER后，可以将检测到的 IBLER值与预设的第二门 限值进行比较； 若 IBLER大于该第二门限值， 则说明上行链路不够稳定， 基站设备可以判断该 UE的上行功率受限； 若 IBLER小于或等于该第二门 限值， 则说明上行链路稳定， 此时可以开始下一个周期的 IBLER统计。 其 中， 该第二门限值例如可以为 0-1 , 具体可以根据需要设置。
进一步地， 在基站设备检测到该 UE 的上行功率受限后， 可以触发该 UE进行切换， 由此降低 UE的掉话率。
步骤 203、 若判断出 UE的上行功率受限， 触发该 UE进行小区切换。 例如， 在基站设备判断到该 UE的上行功率受限后， 可以触发该 UE进 行间隙性邻区 （GAP ) 测量， 对异频或异系统邻区的信号质量进行测量， 若信号质量满足要求（例如满足触发切换的事件 )， 则触发该 UE进行小区 切换。 该 GAP测量可以为异频 GAP测量， 也可以为异系统 GAP测量。 当 本实施例应用在异频网络时， 该 GAP测量为异频 GAP测量； 当本实施例 应用在异系统时， 该 GAP测量为异系统 GAP测量。
当该 UE上报的测量报告满足要求时， 可以由基站设备判决发起切换。 其中， 上述方法中还可以包括以下步骤：
步骤 202B、 在基站设备检测 UE发送的上行数据包的 IBLER时， 基站 设备继续检测该 UE发送的上行数据包的 MCS;
步骤 202C、 若基站设备检测到第三预定数量的该 UE发送的上行数据 包的 MCS的阶数大于第四门限值， 则可以停止检测该 UE发送的上行数据 包的 IBLER, 即停止步骤 202中获取该 UE发送的上行数据包的 IBLER的 动作。 调制编码方式的阶数大于第四门限值的第三预定数量的上行数据包 是连续的。 其中， 该第三预定数量与前述的第一预定数量是独立的两个参 数， 可以根据需要分别配置； 第四门限值具体可以根据需要设置， 且第四 门限值大于或等于第一门限值。
增加了上述步骤 202B和步骤 202C后， 当基站设备检测到某一 UE发 送的、连续的第三预定数量的上行数据包的 MCS的阶数大于第三门限值时， 表示当前该 UE的上行链路稳定，可以不进行小区的切换， 由此也就可以不 进行上行数据包的 IBLER统计。 而步骤 202B和步骤 202C是可选的， 在图 中未示出。
需要说明的是， 在另一种实施例方式中， 本实施例中的步骤 202可以 由以下步骤 202，替换； 步骤 202，为：
若在预设时间内， 第一预定数量的该 UE发送的上行数据包的 MCS的 阶数小于第一门限值， 且确定出该 UE发送的上行数据包的 IBLER大于第 二门限值， 则判断该 UE的上行功率受限。
具体的， 步骤 202，可以为： 针对某一 UE发送的上行数据包， 在一预 设的时间段内，如果有一定数量的上行数据包的 MCS的阶数小于第一门限 值， 且确定出该 UE发送的上行数据包的 IBLER大于第二门限值， 则判断 该 UE的上行功率受限； 其中， MCS的阶数小于第一门限值的这些上行数 据包可以是不连续的； 例如： 从开始检测的时刻启动一定时器， 在定时器 没有超时前， 若有预定数量的上行数据包的 MCS的阶数小于第一门限值， 则基站设备可以对该 UE发送的上行数据包的 IBLER进行判断， 以判断该 UE的上行功率是否受限。 其中， 基站设备对上行数据包的 IBLER的判断 过程参见上述步骤 202中的描述。
本实施例可以采用 MCS和 IBLER作为上行功率受限的判断标准。 即 当一定数量的上行数据包的 MCS的阶数低于第一门限值， 并且 IBLER在 此后的一预设长度的时间内高于第二门限值时，基站设备确定出 UE的上行 功率受限， 可以对该 UE执行小区切换。 其中， 第一门限值和第二门限值可 以根据系统的实际情况来设置。
本发明实施例，通过检测 MCS和 IBLER能够准确表征 UE的上行信号 受限的情况， 能够在发现 UE的上行链路受限时及时发起切换， 降低 UE的 掉话率。

或者， 判断单元 33具体可以用于： 若在预设时间内， 第一预定数量的 所述终端发送的上行数据包的调制编码方式的阶数小于第一门限值， 且确 定出所述终端发送的上行数据包的初始误块率大于第二门限值， 判断出所 述终端的上行功率受限。
