本发明涉及网络部署领域， 尤其涉及一种小区重选方法、 装置和小区 参数配置方法、 装置。 背景技术
在实际的 UMTS Hetnet ( Universal Mobile Telecommunications System Heterogeneous Network, 通用移动通信***异构网络）部署中， 会发生用户 的上下行链路不平衡的问题， 相关技术中解决上述不平衡的问题， 一般釆 用两种方法： 一种是釆用在宏小区中部署同频的低功率基站， 如微小区 ( Micro小区）、 微微小区（Pico小区）， 来解决急速增长的数据流量以及各 种基于移动互联网应用的 APP应用需求， 这些低功率基站部署在宏小区中 来实现对热点的补充覆盖， 形成宏小区与低功率小区共存的 Hetnet异构网 络； 还有一种是增强低功率小区导频技术， 该技术主要是增强了 P-CPICH/P-CCPCH/P-SCH/S-SCH信道覆盖，可以让在不平衡区域中的终端 完成软切换过程。 如图 1 所示， 低功率小区的主公共导频下行边界与原有 的下行业务边界之间实现了空间分离， 使得软切换区边界移到不平衡区的 上行边界区域， 实现了低功率小区的导频与下行业务之间的差异化覆盖策 略， 低功率小区导频、 广播、 同步信道大覆盖， 低功率小区下行业务覆盖 小覆盖。
对于第二种解决上下链路不平衡的问题， 由于低功率基站增强了公共 导频发射功率， 因此， 在该不平衡区域中存在一个导频功率增强区域， 在 相关技术中，当终端处于该导频功率增强区域时，即低功率小区的 P-CPICH ( Principal Common Pilot Channel， 主公共导频信道） 导频边界区域与 HS-PDSCH ( High-Speed Physical Downlink Shared Channel, 高速物理下行 共享信道） 的下行边界之间的区域， 处于空闲 （IDLE )状态的终端测量到 低功率小区的 P-CPICH导频功率比较大， 会导致终端将低功率小区选择为 驻留小区。 但是该区域的移动用户的 HS-DSCH ( High-Speed Downlink Shared Channel, 高速下行链路共享信道）服务小区和 E-DCH ( Enhanced Dedicated Channel, 增强的专用信道）服务小区是宏小区， 所以， 当终端处 于空闲状态且选择宏小区作为服务小区时， 在该区域需要进行信令切换， 由于处于不平衡区域， 在信令切换的过程中存在信令切换失败的情况， 给 用户终端的使用带来不便。 所以， 在终端处于不平衡区域的导频功率增强 区域时， 如何减少小区信令变更以及减少信令切换失败的概率是亟待解决 的问题。 发明内容

实施例一：
图 2是本实施例提供的小区重选方法， 该方法包括：
步骤 201 : 设置宏小区覆盖区中的增强型低功率小区的小区重选参数； 步骤 202: 当终端位于所述增强型低功率小区的导频功率增强区时，根 据所述增强型低功率小区和所述宏小区的小区重选参数选择所述宏小区为 所述终端的服务小区。
在上述步骤 201 中， 优选地， 所述设置宏小区覆盖区中的增强型低功 率小区的小区重选参数的设置命令可以来自于网络侧的网络控制器， 也可 以来自于基站控制器， 所述设置宏小区覆盖区中的增强型低功率小区的小 区重选参数的执行主体可以为基站本身， 也可以为第三方设置装置， 在本 实施例中优选为基站， 所述的增强型低功率小区是宏小区覆盖的低功率小 区； 所述的增强型低功率小区是增强了公共导频发射功率的低功率小区， 所述增强型低功率小区的 "增强" 体现在： 增强型低功率小区的导频功率 所占小区最大发射功率的比例相比较于普通低功率小区的导频功率所占小 区最大发射功率的比例大。
在上述步骤 202 中， 本实施例中， 优选地， 终端处于空闲状态， 当其 位于所述增强型低功率小区的导频功率增强区时， 终端会基于所述增强型 低功率小区和所述宏小区的小区重选参数选择宏小区作为服务小区， 而不 是低功率小区， 所述的导频功率增强区同时也位于上下行业务链路的不平 衡区域内， 在本实施例中， 优选地， 终端处于导频功率增强区且在空闲状 态时能够选择宏小区作为服务小区。
较佳地，在上述步骤 201中，所述小区重选参数为其包含的比选参数， 所述的比选参数是进行小区选择和重选的质量度量标准。 在本实施例中， 优选比选参数作为重新设定的小区重选参数， 当然， 所述的重选参数还可 以是能够进行小区选择与重选的其他参数， 不限于本实施例中的优选参数。 在本实施例中， 优选地， 设定宏小区覆盖区中的增强型低功率小区的小区 重选参数的具体过程优选为： 增强型低功率小区接收来自网络侧的***更 新消息， 该***更新消息包括相应的参数设置规则， 当接收到该消息后， 才进行增强型低功率小区重选参数的重新设定， 该***更新消息也不限于 本实施例中优选地来自与网络侧， 也可以来自于第三方的设备， 当该设备 检测到终端处于增强型低功率小区的导频功率增强区域时， 会向增强型的 低功率小区发送***更新消息。
较佳地， 按照***更新消息中相应的参数设置规则设置增强型低功率 小区的小区重选参数的具体方法优选为： 增大增强型低功率小区的比选参 数， 使得增强型低功率小区的比选参数大于宏小区比选参数。 这样做的目 的是增大了增强型低功率小区的小区选择与重选难度， 使得终端在导频功 率增强区域， 不能够轻易的选择增强型的低功率小区作为服务小区， 从而 进行其他小区的选择， 本实施例中选择宏小区作为服务。
在本实施例中， 通过设定增强型低功率小区的比选参数大于所述宏小 区比选参数来实现终端在导频功率增强区域选择宏小区作为服务小区的目 的。 当然， 也不失一般性， 可以通过改变其他参数的设置， 使得终端处于 导频功率增强区域时能够轻易的选择宏小区作为服务小区。
较佳地， 增大增强型低功率小区的比选参数， 使得增强型低功率小区 的比选参数大于宏小区比选参数优选的方法为： 给宏小区的比选参数增加 一个比选参数调整阈值， 改变低功率小区的比选参数等于增加比选参数调 整阈值后的宏小区的比选参数， 当然， 也可以是使得增强型低功率小区的 比选参数在原有参数值的基础上增加一个比选参数调整阈值， 增加该比选 参数调整阈值以后能够保证增强型的低功率小区的比选参数大于宏小区的 比选参数。 通过该方法， 可以使得增强型的低功率小区的比选参数大于宏 小区的比选参数， 在该情况下， 当终端处于导频功率增强区域， 由于增强 型低功率小区的比选参数大于宏小区的比选参数。 所以， 终端由于无法选 到低功率小区作为服务小区， 进而重新选择比选参数不大的宏小区作为服 务小区， 在本实施例中， 所述的比选参数调整阈值大于 0， 具体数值的设置 根据实际情况而定。
较佳地， 所述的比选参数调整阈值可以是任何一个固定的数值， 只要 保证在增加该比选参数调整阈值后满足增强型的低功率小区的比选参数大 于宏小区的比选参数即可， 在本实施例中， 优选地， 所述的比选参数调整 阈值为低功率小区的增强功率导频与未增强功率导频的比值， 所述的低功 率小区是增强了公共导频发射功率的低功率小区， 即是增强型低功率小区。
较佳地， 所述比选参数至少包括 Qqualmin、 Qrxlevmin, 其中， 该比选 参数还分为增强型低功率小区的比选参数 Qqualmin或 /和 Qrxlevmin, 宏小 区的比选参数 Qqualmin或 /和 Qrxlevmin。
为了描述的需要，用 Qqualmin— LPN表示低功率小区成为合适小区的最 'J、 CPICH Ec/N0； 用 Qrxlevmin— LPN表示低功率小区成为合适小区的最小 CPICH RSCP; 用 Qqualmin— macro表示宏小区成为合适小区的最小 CPICH Ec/NO;用 Qrxlevmin— macro表示宏小区成为合适小区的最小 CPICH RSCP。
在本实施例中， 所述的 CPICH Ec/NO和 CPICH RSCP表示小区选择和 重选的质量度量标准， 即为小区选择和重选的比较参数。
上述小区重选方法的实现， 可以通过软件来实现也可以通过硬件实现。 釆用本实施例中的方法， 重新设置宏小区覆盖区中的增强型低功率小 区的小区重选参数， 使得终端处于导频功率增强区域时， 能够直接选择宏 小区作为服务小区， 而不需要选择增强型低功率小后再进行信令的切换， 能够避免信令切换的复杂度高以及信令切换失败概率大的问题。
实施例二：
图 3是本实施例中提供的小区参数配置方法， 该方法包括：
步骤 301 : 接收小区重选参数设置命令， 该小区重选参数设置命令包括 小区重选参数设置规则；
步骤 302: 根据所述小区重选参数设置命令，对宏小区中相应的增强型 低功率小区的小区重选参数按照所述小区重选参数设置规则进行设置， 使 位于所述增强型低功率小区导频功率增强区的终端选择所述宏小区为服务 小区。 在上述步骤 301 中， 基站接收到的小区重选参数设置命令可以来自于 网络端的网络控制器， 也可以来自于基站控制器， 本实施例中优选来自与 基站控制器， 所述的增强型的低功率小区是宏小区覆盖的低功率小区； 所 述的增强型低功率小区是增强了公共导频发射功率的低功率小区， 所述增 强型低功率小区的 "增强" 体现在增强型低功率小区的导频功率所占小区 最大发射功率的比例相比较于普通低功率小区的导频功率所占小区最大发 射功率的比例大。
在本实施例中， 所述的小区重选参数设置规则包括： 设置所述小区重 选参数包含的比选参数。
在上述步骤 302 中， 基站根据接收到的小区重选设置命令， 对宏小区 覆盖区域中的增强型低功率小区中的重选参数进行配置， 所述的配置按照 小区重选设置命令中的小区重选参数设置规则进行设置， 使位于该宏小区 覆盖区域中的增强型低功率小区的导频功率增强区域的终端选择宏小区作 为服务小区。
在本实施例中，优选地，选择宏小区为服务小区的终端处于空闲状态。 较佳地， 在上述步骤 301 中， 所述的小区重选参数设置规则包括设置 所述小区重选参数包含的比选参数， 所述的比选参数是进行小区选择和重 选的质量度量标准。
较佳地， 在上述步骤 301 中， 对宏小区中相应的增强型低功率小区的 小区重选参数按照所述小区重选参数设置规则进行设置包括： 增加比选参 数调整阈值， 使所述增强型低功率小区的比选参数大于所述宏小区的比选 参数。 具体的设置规则在本实施例中优选为， 给增强型低功率小区重选参 数中的比选参数增加一个比选参数调整阈值， 该阈值可以为任意大于零的 数值， 在本实施例中， 优选地， 所述的必选参数调整阈值为低功率小区的 增强功率导频与未增强功率导频的比值。
实施例三： 下面在图 4所示的通信***基础上， 对本发明做进一步的说明。
在图 4 中， 存在一个宏小区和一个低功率小区， 所述的低功率小区是 宏小区覆盖区域的低功率小区， 所述的低功率小区增强了公共导频发射功 率；
网络侧的网络控制器（ Radio Network Controller， NC )向低功率小区 发送***信息更新消息， 低功率小区根据接收到的***信息更新消息进行 小区重选参数的改变。
当终端处于该导频功率增强区且所述终端处于空闲 （IDLE )状态时， 终端接收来自不同小区的重选参数， 在本实施例中， 优选终端接收来自主 公共控制物理信道（ Primary Common Control Physical Channel, P-CCPCH ) 中的重选参数， 由于低功率小区 P-CCPCH信道中的重选参数已经被修改， 且低功率小区修改后的重选参数比终端中原有检测到的参数要大， 致使终 端不能够选择低功率小区作为服务小区， 转而选择宏小区作为服务小区。
在本实施例中， 网络侧的 RNC向低功率小区发送***信息更新消息， 所述的***更新消息包括***信息块 SIB11或 /和 SIB12,在该信息块 SIB11 或者 SIB12中又包括比选参数 Qqualmin和 Qrxlevmin, 其中， 为了描述的 需要，用 Qqualmin— LPN表示低功率小区成为合适小区的最小 CPICH Ec/NO; 用 Qrxlevmin— LPN表示低功率小区成为合适小区的最小 CPICH SCP; 用 Qqualmin— macro 表示宏小区成为合适小区的最小 CPICH Ec/N0； 用 Qrxlevmin— macro表示宏小区成为合适小区的最小 CPICH RSCP。
在本实施例中， 所述的 CPICH Ec/N0和 CPICH RSCP表示小区选择和 重选的质量度量标准， 即为小区选择和重选的比较参数。
低功率小区根据接收到的***信息更新消息进行小区重选参数的改变 的具体方法是： 当低功率小区接收到该***更新消息以后， 根据***信息 更新消息中的内容对低功率小区中的对应小区比选参数进行改变， 具体的 改变方式是给对应的小区比选参数增加一个比选参数阈值， 也即增大了低 功率小区中的小区比选参数， 使得低功率小区的重选难度增大。 在本实施 例中， 优选地， 给增强型低功率小区中的比选参数增加的阈值 Delta为低功 率基站增强功率导频与未增强功率导频的比值， 单位为 dB。 此时， 低功率 小区将调整后的参数通过 P-CCPCH信道广播出去，使得位于低功率小区导 频功率增强区域的终端可以接受的到该参数信息。
小区重选参数被修改用公式可表示为：
Qqualmin_LPN=Qqualmin_macro+Delta
和
Qrxlevmin_LPN= Qrxlevmin macro+Delta；
在本实施例中 ， 需要满足上述参数 Qqualmin— LPN 和参数 Qrxlevmin LPN 同时增大时， 位于低功率小区导频功率增强区域的终端才 会选择宏小区作为服务小区。 同时， 需要满足终端此时处于空闲状态。
利用上述的方式增强低功率小区的小区重选参数保证了低功率小区的 小区比选参数大于宏小区的小区比选参数， 使得终端能够最终选择宏小区 作为服务小区。

在本实施例中， 设置所述小区重选参数包含的比选参数具体为： 给宏 小区覆盖区域对应的增强型低功率小区重选参数的比选参数增加一个阈值， 使得该比选参数大于对应宏小区的比选参数， 这样， 使得终端在选择服务 小区时， 选择宏小区为服务小区。 所述的阈值为任意不为零的数， 在本实 施例中优选为低功率小区的增强功率导频与未增强功率导频的比值。
所述小区重选模块 502才艮据处于空闲状态的终端所处的位置， 为终端 选择宏小区为服务小区。
