本发明提供的方法可利用小区中的 UE 上报的测量报告来获取邻区的 覆盖率, 进而获取邻区之间覆盖关系, 且可自动发现并优化同频、 异频、 异系统的邻区覆盖关系, 实现简单, 运营成本低。 下面通过具体实施方式 结合附图对本发明作进一步详细说明。
实施例一
本例中的本端小区根据在其覆盖范围内的 UE 上报测量报告的次数和 上报的测量报告中包含同一邻区的测量报告的个数得到该邻区在所述小区 内的覆盖率。 本例中小区的覆盖范围是指小区的实际覆盖范围, 而非平常 所指的理论覆盖。 下面以实例说明理论覆盖与实际覆盖的区别:
4叚设存在两个有相邻关系的小区 A和 B, 且小区 A和 B的覆盖半径都 是 1000米, 这里说的 1000米是小区的理论覆盖, 也就是说理论上在距离 基站 1000米位置的 UE仍能接入通话, 但在实际布网中 UE可能在距离基 站 800米的位置就已经接入或切换到其他小区了, 所以上述两小区间的实 际覆盖范围的半径应是 800米。从 UE的移动性角度出发,基站更关注小区 间的实际覆盖。 本例中小区内的 UE上传的测量报告是指切换测量报告。
本例以上述小区 A为本端小区,上述小区 B为小区 A在某一频点的下 的多个邻区中的一个邻区 B为例, 对本发明做进一步说明, 请参见图 1 ;
接收本端小区 A内 UE在某频点下上报的测量报告, 并获取本端小区 内 A内 UE在该频点下上报测量报告的次数;
解析所述上报的测量报告, 以获取上报的测量报告中包含同一邻区 B 的测量报告的个数;
根据本端小区 A内 UE在该频点下上报测量报告的次数和上报的测量 报告中包含邻区 B的测量报告的个数得到邻区 B在本端小区 A内的覆盖率。 其中, 根据本端小区 A内 UE在该频点下上报测量报告的次数和该上报测 量报告中包含邻区 B的测量报告的个数得到邻区 B在本端小区 A内的覆盖 率包括:
设置测量报告上报门限值,同时设置用于统计 UE上传测量报告次数的 第一计数值和用于统计包含有所述邻区 B的测量报告个数的第二计数值; 本端小区内 UE在该频点下上传一次测量 4艮告, 第一计数值增加 1 , 同 时当判断出该测量报告中包含邻区 B时, 第二计数值增加 1 ;
当第一计数值等于测量报告上报门限值时, 将当前的第二计数值除以 测量报告上报门限值或除以当前的第一计数值, 得到邻区 B在本端小区 A 内的覆盖率。
在判断该测量报告中包含邻区 B时, 可根据在设置测量报告上报门限 值的步驟中同时设置的邻区信号质量门限值进行判断, 当测量报告中包含 的邻区 B信号质量大于邻区信号质量门限值, 才判定该测量报告包含该邻 区 B; 否则, 判定为该测量报告不包含邻区 B。
本例中小区中的 UE根据 LTE下发的测量配置上报测量报告, 其中所 述测量配置可包括异频切换测量配置、 同频切换测量配置、 异系统切换测 量配置, 因此本例提供的方法可自动发现并优化同频、 异频、 异系统的邻 区覆盖关系, 不区分无线接入制式, 可以判断 LTE 内部 (TDD-LTE , FDD-LTE ) 同频、 异频邻区之间的覆盖关系及各种制式 (UTRAN-TDD, UTRAN-FDD, CDMA-HRPD, CDMA-lxRTT, GERAN )邻区之间的覆盖 关系;且本例根据 UE上传的测量报告获取邻区覆盖率,屏蔽了无线系统的 复杂性, 最真实的反应了小区之间的覆盖关系, 实现简单, 运营成本低。
本例在通过上述方法获取了邻区的覆盖率的基础上, 还提供了一种获 取邻区覆盖关系的方法, 具体如下:
本端小区 A和与之对应的邻区 B分别根据如上所述的方法得到邻区 B 在本端小区 A内的第一覆盖率和本端小区 A在邻区 B内的第二覆盖率; 本端小区 A根据上述第一覆盖率和第二覆盖率得到与邻区 B之间的覆 盖关系。
本例中, 本端小区 A在得到所述第一覆盖率之后, 还包括将其发送给 邻区 B的步驟; 同样, 在邻区 B得到所述第二覆盖率之后, 还包括将其发 送给本端小区 A的步驟, 在小区之间发送上述覆盖率时刻根据实际情况选 择通过 S1接口、 X2接口或站内通信接口进行转发。
本例中邻区之间的覆盖关系包括同覆盖关系、 被包含覆盖关系、 包含 覆盖关系以及相邻覆盖关系。 请参见图 2-图 5。
对于同覆盖关系, 如图 1所示, 驻留在小区 A的 UE上报测量报告中 存在邻区 B的概率趋于 100%,同时驻留在小区 B的 UE上报测量报告中存 在邻区 A的概率趋于 100%;
对于被包含覆盖关系, 如图 3所示, 驻留在小区 A的 UE上报测量报 告中存在 B的概率趋于 100%,驻留在小区 B的 UE上报测量报告中存在邻 区 A的概率应趋于某一固定值 Coverage, Coverage的大小取决于两小区覆 盖范围重合的比例;
对于包含覆盖关系, 如图 4所示, 与包含关系类似, 驻留在小区 B的 UE上换测量报告中存在邻区 A的概率趋于 100%, 驻留在小区 A的 UE上 报测量报告中存在邻区 B的概率应趋于某一固定值 Coverage, Coverage的 大 d、取决于两小区覆盖范围重合的比例;
对于相邻覆盖关系, 如图 5所示, 驻留在小区 A中的 UE上报测量报 告存在邻区 B的概率趋于某一固定值 Coverage 1 ,驻留在小区 B中的 UE上 报测量报告存在 A 的概率趋于某一固定值 Coverage2 ; Coverage 1 和 Coverage2的大小取决于两小区覆盖范围重合的比例。
通过上面的分析, 如果定义覆盖特征二元组:
覆盖特征<小区 A中邻区 B的覆盖率, 小区 B中邻区 A的覆盖率> 则有
同覆盖特征 <趋近 100%, 趋近 100%>
被包含关系特征 <趋近 100% , 趋近 Coverage>
包含关系特征 <趋近 Coverage , 趋近 100%>
相邻关系特征 <趋近 Coverage 1 , 趋近 Coverage 2>
因此, 本例中可通过上述覆盖特征来辨别各邻区覆盖关系。 仍以上述 本端小区 A和邻区 B为例,本例可在在本端小区 A获得上述第一覆盖率和 第二覆盖率之前, 还包括设置覆盖率最大门限值步驟, 本端小区 A获得第 一覆盖率和第二覆盖率之后, 将第一覆盖率和第二覆盖率与覆盖率最大门 限值进行比较, 根据比较结果得到与邻区 B之间的覆盖关系, 具体如下: 本端小区 A将第一覆盖率和第二覆盖率与覆盖率最大门限值进行比 较, 如果都大于覆盖率最大门限值, 则表明邻区 B在本端小区 A内的覆盖 率趋近于 100%, 同时本端小区 A在邻区 B内的覆盖率也趋近于 100%, 因 此此时本端小区 A与邻区 B之间的覆盖关系为同覆盖。
本端小区 A将第一覆盖率和第二覆盖率与覆盖率最大门限值进行比 较, 如果第一覆盖率大于覆盖率最大门限值, 第二覆盖率小于覆盖率最大 门限值,则表明邻区 B在本端小区 A内的覆盖率趋近于 100%,本端小区 A 在邻区 B内的覆盖率低于覆盖率最大门限值, 因此此时本端小区 A与邻区 B之间的覆盖关系为被包含覆盖关系, 即本端小区 A被包含于邻区 B中。
本端小区 A将第一覆盖率和第二覆盖率与覆盖率最大门限值进行比 较, 如果第一覆盖率小于覆盖率最大门限值, 第二覆盖率大于覆盖率最大 门限值, 则表明邻区 B在本端小区 A内的覆盖率低于覆盖率最大门限值, 本端小区 A在邻区 B内的覆盖率趋近于 100%, 因此此时本端小区 A与邻 区 B之间的覆盖关系为包含覆盖关系, 即本端小区 A包含邻区 B中。
本端小区 A将第一覆盖率和第二覆盖率与覆盖率最大门限值进行比 较, 如果第一覆盖率小于覆盖率最大门限值, 第二覆盖率也小于覆盖率最 大门限值,则表明邻区 B在本端小区 A内的覆盖率低于覆盖率最大门限值, 本端小区 A在邻区 B内的覆盖率也低于覆盖率最大门限值, 因此此时本端 小区 A与邻区 B之间的覆盖关系为相邻覆盖关系, 即本端小区 A和邻区 B 存在不完全重合的区域。
本例中的本端小区 A在得到与邻区 B之间的覆盖关系后, 还可包括根 据得到的覆盖关系更新与邻区 B之间的覆盖关系, 具体如下:
本端小区 A判断与邻区 B之间的当前覆盖关系是否与所述本端小区得 到的覆盖关系相同, 如否, 则将其更新为上述步驟得到的与邻区 B之间的 覆盖关系。
同时, 本例中为了进一步有效的获取邻区之间的覆盖关系, 还可设置 覆盖率最小门限以对覆盖率较小的邻区进行删除, 保证获取的邻区覆盖关 系的可靠性和实用性。 具体的, 可在本端小区 A获得第一覆盖率前, 设置 覆盖率最小门限, 本端小区 A得到第一覆盖率之后, 将得到的所述第一覆 盖率与所述覆盖率最小门限进行比较, 如小于所述覆盖率最小门限, 则将 邻区 B删除, 即此时邻区 B不再是本端小区 A的邻区。
本例中的邻区和本端小区是根据可以互换的, 即在获取小区 A的邻区 覆盖关系时, 小区 A为本端小区, 小区 B为本端小区 A的邻区; 同样, 当 获取小区 B的邻区覆盖关系时, 小区 B为本端小区, 小区 A为本端小区 B 的邻区。
本发明还提供了一种用于获取邻区覆盖率的装置, 该装置包括用于根 据如上所述的方法获取邻区覆盖率的统计模块。
进一步地, 本发明还提供了一种用于获取邻区覆盖关系的系统(本例 中的系统可作为基站), 请参见图 6, 该系统包括如上所述的获取邻区覆盖 率装置, 还包括与该装置连接的收发装置和处理装置, 收发装置同时还与 处理装置连接, 收发装置用于发送本端小区获取的覆盖率和接收邻区发送 过来的覆盖率。 处理装置用于根据本端小区获取的覆盖率和接收邻区发送 过来的覆盖率得到本端小区和邻区之间的覆盖关系, 具体如下: 处理装置 将本端小区的覆盖率和所述收发装置接收到的覆盖率分别与设定的覆盖率 最大门限进行比较, 根据比较结果得到所述本端 d、区和邻区之间的覆盖关 系。
进一步地, 本例中的系统还包括与上述统计装置连接的切换判决装置 和与该切换判决装置连接的 UE, 切换判决装置用于判决 UE是否满足切换 条件, 如满足, 则通知 UE可上传切换测量报告, 该切换测量报告中至少包 括检测到的邻区的 ID和邻区的信号强度信息。 本例中的 UE上传切换测量 报告给基站是发生在小区的边缘。 基站从切换测量报告中包含的候选小区 中选择一个进行切换。

当 HO— FREQ— MEAS— RPT— COUNT等于 MEAS— RPT— NUM—THRELD 时, 停止统计, 按照下述方法(即以下公式 1 )计算覆盖率 Coverage: Coverage=HO—NBR—MEASRPT— COUNT/HO— FREQ— MEAS— RPT— COUNT; 或
Coverage=HO_NBR_MEASRPT_COU T/MEAS_RPT_NUM_THRELD; 分别按照上述方法计算相邻两邻区相对于对方的覆盖率; 如果覆盖率 Coverage大于 COVERAGE— HIGH邻区发现概率高门限, 则认为覆盖率趋 近于 100%, 如果覆盖率 Coverage低于 COVERAGE— LOW, 则可将该邻区 删除。 下面分别以自动发现、 优化同频、 异频、 异系统的邻区覆盖关系为 例对本发明做进一步说明:
