具体实施方式
本发明的实施例提供一种提高信号质量的方法、 装置、 无线网络控制器和芯片, 通过将第二小区的基站检测得到的属于第一小区的一个用户终端的第一信号和所述第 一小区的基站检测得到的所述用户终端的第二信号进行合并, 从而提升该用用户终端 的信号质量, 解决了因用户终端的信号质量差而引起的网络用户掉话、 单通以及切换 成功率低的技术问题。
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。
实施例一
本实施例提供一种提高信号质量的方法, 如图 1所示, 包括:
步骤 101 : 获取至少一个第二小区的基站检测得到的属于第一小区的用户终端的 第一信号;
步骤 102: 将所述第一信号与所述第一小区的基站检测得到的所述用户终端的第 二信号进行合并得到第三信号;
步骤 103: 将所述第三信号发送给无线网络控制器。
为了更好的理解本发明的技术方案, 在下面的实施例中将以用户终端为 UE (User Equipment) 进行说明。
假设, 第一小区为 UE的服务小区, 第二小区为与第一小区相邻的小区。 由于频点 资源有限, 第二小区很有可能会采用与第一小区相同的频点。 因此, 服务小区的基站 除了会收到本服务小区中 UE的信号外, 还会收到来自与服务小区具有相同频点的第 二小区中 UE的信号。 由于来自第二小区中 UE的信号会对本服务小区中 UE的信号 造成干扰, 因此通常将这些第二小区中的 UE称为干扰 UE。 为了方便描述, 在本实施例中将与第一小区具有相同频点的第二小区称为同频邻 区。 例如, 参见图 2所示, UE的服务小区存在两个同频邻区, 即同频邻区 1和同频 邻区 2, 干扰 UE1属于同频邻区 1, 干扰 UE2属于同频邻区 2, 服务小区在收到 UE 的信号的同时, 也会收到来自干扰 UE1和干扰 UE2的信号。 服务小区的基站可以通 过现有技术中 MCJD联合检测的方法,对收到的信号进行干扰消除, 即消除干扰 UE1 和干扰 UE2的信号, 从而获得服务小区内 UE的信号。 同样, 同频邻区 1的基站或同频邻区 2的基站也可以通过现有技术中 MCJD联合 检测的方法来获得来自服务小区中 UE的信号。
为了提高服务小区中 UE的信号质量, 在实施例中, 可以将服务小区的基站检测 得到的 UE的信号与同频邻区 1的基站和同频邻区 2的基站检测得到的所述 UE的信 号进行合并, 合并后的信号质量很显然优于之前服务小区的基站单独检测得到的 UE 的信号。
上述第二小区和第一小区可以连接至同一个基站, 也可以连接至不同的基站。 上述步骤 102中, 将所述第一信号与所述第一小区的基站检测得到的所述用户终 端的第二信号进行合并得到第三信号具体可以包括:
将所有第二小区的基站检测得到的所述第一信号中的信号强度最大的一个与所述 第二信号进行合并得到第三信号。
例如, 假设上述同频邻区 1的基站检测得到的 UE的信号为信号 1, 同频邻区 2的 基站检测得到的 UE的信号为信号 2,信号 1的信号强度大于信号 2的信号强度。为了 简化计算量,可以只选择一个同频邻区检测到的 UE的信号与服务小区检测得到的 UE 的信号进行合并。 而在本实施例中, 可以优先选择信号强度最大的信号, 即信号 1, 与服务基站检测得到的 UE的信号进行合并得到第三信号。 在本实施例中, 上述将所有第二小区的基站检测得到的所述第一信号中的信号强 度最大的一个与所述第二信号进行合并得到第三信号可以通过如下方式来实现: 接收所述无线网络控制器发送的 wc/ , 所述 ^>^/ 为无线网络控制器从所 有第二小区的基站发送的接收信号码功率 RSCP (received signal code power) 中 选择值为最大的一个,所述 RSCP为所述第二小区的基站接收所述用户终端的信 号时测得的所述第二小区的基站的信号的接收信号码功率;
将与所述 对应的所述第二小区的基站检测到的所述用户终端的信号作 为所述第一信号与所述第二信号进行合并得到所述第三信号。
所述第一小区的基站和所述至少一个第二小区的基站分别通过多小区联合检测得 到所述用户终端的第二信号和所述用户终端的第一信号。
上述步骤 103 中, 所述第一小区的基站将所述第三信号发送给无线网络控制器包 括:
第一小区的基站将所述第三信号封装成帧后发送给所述无线网络控制器。 本实施例的方法可以由第一小区的基站执行, 也可以由除所述第一小区的基站和 所述无线网络控制器外的其他实体执行。
如果本事是了的方法由除所述第一小区的基站和所述无线网络控制器外的其他实 获取所述第一小区的基站检测得到的所述用户终端的第二信号。 下面将通过更为具体的例子进行说明。
如图 3所示, 在本实施例中, 假设第一小区 303为 UE 304的服务小区, 第二小区 302为第一小区 303的同频邻区,这里的第二小区可以有一个, 也可以有多个。为了方 便理解, 本实施中以第二小区只有一个为例进行说明, UE 304的信号可以到达第二小 区 302所属的基站。 第二小区 302的基站既能收到第二小区中 UE 的信号, 也能收到 来自 UE 304的信号。 因此, 对于第二小区 302而言, 该 UE 304为第二小区 302的干 扰 UE, 第二小区的基站通过多小区联合检测 MCJD可以获得 UE 304的信号。
第一小区 303的基站通过多小区联合检测也会获得 UE 304的信号,将第二小区 302 的基站与第一小区 303的基站获得的 UE 504的信号进行合并后, UE 304的信号质量 就会得到提升。
当与第一小区 303相邻的同频邻区有多个, 即第二小区 302有多个时,每个第二小 区 302的基站收到的 UE 304的信号都可以通过多小区联合检测 MCJD检测出来,将所 号进行合并, 从而可以提高该 UE 304的信号质量。
上述方法可以由第一小区的基站执行, 也可以由除所述第一小区的基站和所述无 线网络控制器外的其他实体执行。 上述第一小区和第二小区可以属于同一个基站, 也 可以属于不同的基站。
在本实施当中, 当存在多个第二小区 302时,这些第二小区 302的基站均会收到来 自服务小区中 UE 304的信号, UE 304也可以接收到来自所述第二小区 302的基站发 来的信号, 并可测得来自所述第二小区的基站的信号的接收信号码功率 RSCP , UE 304将该测得的 RSCP发送给对应的每个第二小区 302的基站, 第二小区 302 的基站再将接收到的 RSCP发送给无线网络控制器 RNC。 RNC会根据所接收到 的 RSCP , 选择值为最大的一个, 为 RSCPAdge , 将与 ^C/^j†应的第二小区 302 的基站所检测出来的该服务小区用户 UE 304的信号, 与第一小区 303的基站所检测 出来的 UE 304的信号进行合并。 这样, 就舍弃了那些收到该服务小区用户 UE 304信 号较弱的第二小区 303的基站所检测出来的服务小区用户 UE 304的信号,减少了合并 时的计算量。
优先地, 上述方法可以由第一小区的基站执行, 或可以由除所述第一小区的基站 和所述无线网络控制器外的其他实体执行, 合并后的信号可以封装成帧后再发送给 可以给第一小区配置多个同频邻区信息, 即与该第一小区相邻的、 并且具有相同 频率的第二小区的信息。
RNC为所述第一小区 303配置同频邻区信息, 所述同频邻区信息包括邻区码 树信息、 邻区用户占用码树资源的指示信息和邻区扰码信息。
当信号合并在第一小区 303的基站进行时, 结合图 3和图 4及上述描述过程, 下 面用一个更加具体的过程详细描述本发明所述方法的完整步骤:
401 : 作为可选步骤, RNC 301通知 UE 304周期性的测量并上报接收信号码 功率 RSCP ;
所述 RSCP是 UE 304测得的来自第二小区 302基站的信号的接收信号码功 率。 当存在多个第二小区 302时, UE 304必须向每个第二小区 302的基站上报 所述 RSCP , 第二小区 302的基站再将接收到的 RSCP发送至 RNC 301。
402 : 更优地, RNC 301选择所述 RSCP中值为最大的一个, 为了方便描述, 将其称为 。 本实施例中, 将与 ^^¾ 所对应的第二小区 302的基站所检 测出来的该服务小区用户 UE 304的信号,发送给第一小区 303的基站, 第一小区 303 的基站将其与第一小区 303的基站所检测出来服务小区 UE 304的信号进行合并。
更佳地, 当 RNC 301发现 RSCP的 RSCPAdge小于预设在 RNC 301 内的门限值 MacroDiversityRNCAbsThreshod时, 即:
RSCPAdge < MacroDiversityRNCAbsThreshold,则认为 RSCPAdge对应的 UE 304不是 第二小区 302的干扰 UE ,则第一小区 303的基站不合并所述第二小区 302的基 站检测出来的 UE 304的信号。
如果, 当 RNC 301发现 RSCP的最大值 大于或等于在 RNC301 中预 设的门限值 MacroDiversityRNCAbsThreshod时, 即:
RSCPAdge > MacroDiversityRNCAbsThreshold,则认为该 RSCPAdge对应的 UE 304是第 二小区 302的干扰 UE , 进行下一步骤 403处理: 403 : 本实施' 假设用户 UE304接收 'J、区 303的基站的信

步骤 502: 所述 RNC获取所述第一小区的基站检测得到的所述用户终端的第二信 号;
步骤 503: 所述 RNC将所述第一信号与所述第二信号进行合并得到第三信号。 上述第二小区的数量可以为两个或两个以上, 所述 RNC将所述第一信号与所述第 二信号进行合并得到第三信号包括:
可选地, 所述 RNC将获取到的所有第二小区的基站检测得到的属于第一小区的所 述用户终端的第一信号中的信号强度为最大的一个与所述第二信号进行合并得到第三 信号。
所述无线网络控制器将获取到的所有第二小区的基站检测得到的属于第一小区的 一个用户终端的第一信号中的最大值与所述第二信号进行合并得到第三信号包括: 无线网络控制器接收每个相邻第二小区的基站发送的 RSCP , 所述 RSCP所述 用户终端接收每个第二小区的基站发送的信号时测得的接收信号码功率;
从所有第二小区的基站发送的 RSCP中选择值为最大的一个,为了方便描述, 以下称为 ^CP^ ;
将与所述 对应的第二小区的基站检测到的所述用户终端的信号作为所 述第一信号与所述第二信号进行合并得到所述第三信号。
所述第一小区的基站和所述至少一个第二小区的基站分别通过多小区联合检测得 到所述用户终端的第二信号和所述用户终端的第一信号。
所述第二小区为所有与第一小区具有相同频率的相邻小区。 .
如图 6所示, 在本实施例中, 假设第一小区 303为 UE 304的服务小区, 第二小区 302为第一小区 303的同频邻区,这里的第二小区可以有一个, 也可以有多个。为了方 便理解, 本实施中以第二小区只有一个为例进行说明, UE 304的信号可以到达第二小 区 302所属的基站。 第二小区 302的基站既能收到第二小区中 UE 的信号, 也能收到 来自第一小区中 UE 304的信号。 因此, 对于第二小区 302而言, 该 UE 304为第二小 区 302的干扰 UE,通过多小区联合检测 MCJD ,第二小区 302的基站将会获得 UE 304 的信号。
第一小区 303的基站通过多小区联合检测也会获得 UE 304的信号,将第二小区 302 的基站与第一小区 303的基站获得的 UE 304的信号进行合并后, UE 304的信号就会 得到提升。
当与第一小区 303相邻的同频邻区有多个, 即第二小区 302有多个时,每个第二小 区 302的基站收到的 UE 304的信号都会被该第二小区 302的基站通过多小区联合检测 的基站检测出来的信号进行合并, 从而可以提高该 UE 304的信号。
本实施例所述方法可以由所述无线网络控制器执行, 也可以由具有与无线网络控 制器相类似功能的其他网络实体来执行。 上述第一小区和第二小区可以属于同一个基 站, 也可以属于不同的基站。
在本实施当中, 当存在多个第二小区 302时,这些第二小区 302的基站会均会收到 来自服务小区的 UE 304的信号, UE 304也可以接收到来自所述第二小区 302的基站 发来的信号, 并可测得来自所述第二小区 302 的基站的信号的接收信号码功率 RSCP , UE 304会将该测得的 RSCP发送给对应的每个第二小区 302的基站, 第 二小区 302的基站再将接收到的 RSCP发送给无线网络控制器 RNC。 无线网络 控制器 RNC会根据所接收到的接收信号码功率 RSCP,选择接收信号码功率 RSCP 中值为最大的一个, 为了方便描述, 在此称为 将与 所对应的第 二小区 302的基站所检测出来的该 UE 304的信号,与第一小区 303的基站所检测出 来服务小区 UE 304的信号进行合并。 这样, 就舍弃了那些收到该服务小区的 UE 304 信号较弱的第二小区 303的基站所检测出来的服务小区的 UE 304的信号,减少了合并 时的计算量。 可以给第一小区配置多个同频邻区信息, 即与该第一小区相邻的、 并且具有相同

701: 作为可选步骤, RNC 301通知 UE 304周期性的测量并上报 RSCP; 所述 RSCP是 UE 304测得的来自第二小区 302基站的信号的接收信号码功 ^。 当存在多个第二小区 302时, UE 304必须向每个第二小区 302的基站上报 逑 RSCP , 第二小区 302的基站再将接收到的 RSCP发送至 RNC 301。

702 : RNC 501根据 UE 304上报的 和 RSCPAdm, 并计算它们之间的 接收信号码功率差 MacroDiversityLoss, 即: MacroDiversityLoss = RSCPLocal― RSCPAdge

MacroDiversityLoss , 即: MacroDiversityLoss = RSCPLocal - RSCPAdge , 如果
MacroDiversityLoss < MacroDiversityLossThreshold, 如步骤 705所示, 确定该服务小区 用户 UE304不是第二小区 302的干扰 UE ,则第一小区 303的基站不合并所述第 二小区 302的基站检测出来的 UE 304的信号。
步骤 703中, 如果 RNC 301作以下判断 RSCPLocal与 RSCPAdge之间的接收信 功率差 MacroDiversityLoss大于 MacroDiversityRNCAbsThreshod, 贝1 J石角定该 服务小区用户 UE304为第二小区 302的干扰 UE;
704 : 如果判断为是干扰 UE, 第二小区 302的基站将该干扰 UE 304信号检 测出来, RNC 301接收第一小区 302的基站检测出来的 UE 304的信号和接收第 二小区 303的基站检测出来的 UE 304的信号;

更优地, RNC 301选择所述 RSCP中值为最大的一个, 为了方便描述, 此处 RSCPAdge。 本实施例中, 将与 所对应的第二小区 302的基站所检测出 来的该服务小区用户 UE 304的信号, 然后再将其与第一小区 303的基站所检测出来 服务小区 UE 304的信号进行合并。
更佳地,当 RNC 301发现 RSCP的最大值 ^C/> 小于预设在 RNC 301 内的门 限值 MacroDiversityRNCAbsThreshod时, 即:
RSCPAdge < MacroDiversityRNCAbsThreshold,则认为 RSCPAdge对应的 UE 304不是 第二小区 302的干扰 UE ,则第一小区 303的基站不合并所述第二小区 302的基 站检测出来的 UE 304的信号。
如果, 当 RNC 301发现 RSCP的最大值 ^C/>^大于或等于在 RNC301 中预 设的门限值 MacroDiversityRNCAbsThreshod时, 即:
RSCPAdge > MacroDiversityRNCAbsThreshold,则认为该 RSCPAdge对应的 UE 304是第 二小区 302的干扰 UE, 进行下一步骤处理。
