技术领域
本发明涉及宽带码分多址系统测量技术领域，尤其涉及一种宽带码分多址(WCDMA，Wideband Code Division Multiple Access)系统双天线测量方法和装置、存储介质。

WCDMA系统的整个切换过程一般分为测量、判决和执行三个阶段。在测量阶段移动台要进行下行链路的信号质量，以及移动台(以下称为终端UE)所属小区及邻近小区的信号质量等测量，因此在WCDMA系统中，UE测量起着十分重要的作用。

具体实施方式
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。
本发明实施例的基本思想是：采取UE具有主辅两根天线的双天线测量方法，每根天线独自衰落，在实际测量过程中，两根天线同时出现测量值波动很大，测量结果不准确等情况几率很小。因此，UE的测量值取两根天线较高信噪比的测量值，一方面能够提高UE测量能力和性能，使UE驻留在信号强度比较好的小区，另一方面能够根据主辅两根天线的测量值来决定上行发送时主辅两根天线的选择，从而提高UE的发送性能。
具体地，测量通过搜索和监控本小区和周围所有小区基站信号强度，信噪比等参数，在预设的条件下将测量结果汇报给网侧，以便网侧进行判断，评估和执行重选，切换，重配等相关操作。由于室外环境比较复杂，为了提高抗干扰抵消能力，UE采用双天线进行测量，以便将小区接收信号码功率(RSCP，Received Signal Code Power)等准确结果反馈给网侧，使UE能够驻留在信号质量比较好的小区。这里UE测量结果被送到相关的无线资源控制(RRC，Radio Resource Control)层，随后进入无线网络控制器(RNC，Radio Network Controller)判决阶段，也称评估阶段，RNC将UE与基站Node B上报的测量结果与预先的定义的阈值比较，以决定是否进行小区切换。
还需要说明的是，在物理层L1的测量过程中，系统主要采取两种测量类型：
第一种测量类型为，基于测量过程维护的公共导频信道(CPICH，Common Pilot Channel)测量，主要针对小区重选、切换场景下同异频邻区测量，测量类型分为CPICH RSCP测量，CPICH Ec/Io测量，通用地面无线接入(UTRA，Universal Terrestrial Radio Access)载波接收的信号强度指示(RSSI，Received Signal Strength Indication)测量，SFN-CFN OTD测量，SFN-SFN OTD测量和检测小区测量。其中，Ec/Io为信噪比，SFN-CFN OTD为SFN-CFN观测时间差，SFN是Node B的小区系统帧号；CFN是下行和上行专用物理信道DPCH相关的帧记号。这项测量用于切换定时的目的，用来识别激活集小区和邻区的时间差。SFN-SFN OTD为SFN-SFN观测时间差，这项测量用于识别两个小区之间的时间差。
第二种测量类型为，由RX/TX/PC链路维护的测量，该链路表示UE发射功率，包括UE发送-接收(RX-TX)定时差，发射功率测量。测量MEAS过程根据协议栈配置的测量请求，从设备层数据库获取结果周期性上报给 协议栈。参见图1，其示出了RX/TX/PC链路维护的测量过程。
还需要说明的是，本发明实施例主要采用第一种测量类型，即基于测量过程维护的CPICH测量类型进行测量。参见图2，其示出了采用第一种测量类型进行的测量过程。
实施例一
参见图3，其示出了本发明实施例提供的一种WCDMA系统双天线测量方法，所述方法可以包括：
S101、无线网络控制器RNC下发测量控制消息至终端UE，通知终端UE进行相关的参数测量。
具体地，网侧读取系统信息块(SIB，System Information Blocks)或者MC接口消息，由RNC通知协议栈同频异频小区相关测量消息。这里同频测量是指同频小区频内测量，异频测量是指异频小区频间测量。
S102、终端UE接收到RNC发送的测量控制消息后开始进行测量。
需要说明的是，UE在进行双天线测量时首先进行调度层的测量，UE接收并解析协议栈下发的同异频测量请求、UE内部测量请求、测量释放请求等，以及内部激活测量请求(小区搜索测量、路损更新CPICH RSCP测量)。这里，与服务小区频点相同的为同频测量，与服务小区频点不同的为异频测量，在服务小区频点内为UE内部测量。测量释放请求用于对同异频测量和UE内部测量进行释放。
参见图2，在接收并解析协议栈下发的测量请求后，更新测量数据库信息。在测量过程中，每帧向资源表申请资源，相同的资源时间测量单天线所能处理的小区数是双天线的倍数。小区有一个老化的时间，小区老化后需要对该小区申请新的资源，因此，测量根据查询老化的小区数去申请对应的资源长度，申请成功之后资源成功后，将对应的资源起始时间点和小区信息发送给设备层。这里的小区信息为小区定时和小区扰码信息。
图2中，CSR过程是一个小区选择的过程，CSR过程根据UE的内部时钟和Node B的内部时钟获取小区定时及小区扰码，这一过程选定了需要进行测量的小区。
调度层完成内部激活测量的调度，并提供接口函数查询测量结果，其中，内部激活测量主要是针对RSCP测量，是对CPICH RSCP值的更新过程。同时调度层还完成不同状态下进行同异频CPICH RSCP、CPICH Ec/Io、OTD、RSSI以及检测小区的测量调度处理。在接收到设备层上报的测量结果后，处理设备层上报的测量结果，并进行滤波，这里的滤波为最后四次的测量结果取平均值。
在设备层中进行测量时，根据调度层的配置生成CPICH RSCP以及Ec/Io测量、小区预同步相关硬件的配置参数，并配置。其中并行工作的SPSR硬件只支持整套配置主天线或辅天线，所以要按照需求配置；
响应测量相关中断后，读取双天线小区多径信息，若是CPICH RSCP以及Ec/Io测量，则根据算法方案分别计算双天线的测量结果，选取两天线中Ec/Io大的对应的RSCP结果转化为协议栈的格式，上报给调度层；若是小区预同步，则需各自对每根天线的小区进行旁瓣抑制、径检测、同步保护等后处理，将处理之后的主天线的多径信息提供给Rake，同时上报L1S预同步小区的主天线最强径位置信息。多径是指无线电信号从发射天线经过多个路径抵达接收天线的传播现象。
上述设备层的相关硬件参数配置是在调用驱动层完成的。驱动层由设备层调用，完成对CPICH RSCP以及Ec/Io测量相关硬件模块的配置和数据读取。
S103、终端UE向RNC上报测量结果。
可以理解地，终端UE得到测量结果后向RNC上报其所获得的测量结果，该测量结果用于判断终端UE是否需要进行小区切换。
S104、RNC根据UE的测量结果进行小区切换判决。
需要说明的是，RNC所接收到的测量结果为UE的主辅两根天线中测量值的较大值再经过滤波后的值。RNC根据预设的门限值与所接收到的测量结果进行对比，若测量结果达到门限值，则做出UE进行小区切换的判决；若测量结果未达到门限值，则做出UE不进行小区切换停留在原驻留小区的判决。
S105、终端UE根据RNC的小区切换判决结果进行小区切换。
可以理解地，UE在获得RNC的小区切换判决结果后，根据小区切换判决结果进行小区切换或者是保持原驻留小区不变。
实施例二
参见图4，其示出了本发明实施例提供的一种WCDMA系统双天线测量方法，应用于具有主辅两根天线的终端UE，所述方法可以包括：
S201、终端UE接收无线网络控制器RNC下发的测量控制消息，对测量控制消息中所指示的测量参数进行测量。
参见图5，具体的，步骤S201包括步骤S2011至S2013：
S2011、UE的协议栈接收RNC下发的测量控制消息，下发测量请求消息对调度层进行测量。
需要说明的是，无线网络控制器RNC下发测量控制消息“Measurement Control”给终端UE，通知UE进行相关参数的测量。UE需要进行测量的参数包括RSSI、RSCP、Ec/Io值。UE的整个测量流程处理分为测量调度层、测量设备层和测量驱动层。
S2012、调度层根据测量请求消息进行资源申请，获取小区配置信息，并将小区配置信息发送至设备层；其中，小区配置信息包括资源申请起始时间、小区定时和小区扰码。
参见图6，具体的，步骤S2012包括步骤S20121至S20123：
S20121、调度层解析协议栈下发的测量请求消息，将频点和当前小区信息存入测量数据库中。
需要说明的是，测量请求消息包括同异频测量请求、UE内部测量请求、测量释放请求等，以及内部激活测量请求(小区搜索测量、路损更新CPICH RSCP测量)。将频点和当前小区信息存入测量数据库中，更新测量数据库的信息。
S20122、从测量数据库中获取频点和当前小区信息，开始小区搜索CSR，获取小区数量、小区定时和小区扰码信息。
参见图7，具体的，步骤S20122包括步骤S201221至S201222：
S201221、当频点和小区信息满足非盲频点或非检测集的测量条件时，确定小区搜索为指定小区的小区搜索CSR。
需要说明的是，对非盲频点或非检测集的测量，被搜索的小区是明确的，因此小区搜索为指定小区的小区搜索CSR。
S201222、当频点和小区信息满足盲频点或检测集的测量条件时，确定小区搜索为CSR盲搜。
需要说明的是，盲频点为已知频点，但是频点下面的小区是未知的，因此盲频点时小区搜索为CSR盲搜。检测集中的小区不是当前服务小区的邻区，因此也需要进行CSR盲搜。
S20123、根据小区搜索CSR搜索到的小区数量，测量MEAS在资源表中申请对应的资源，把小区配置信息发送至设备层。
需要说明的是，根据需要处理的小区测量MEAS每一帧在资源表中申请资源，由于UE有主辅两根天线，因此相同的资源时间仅测量单天线所能测量的小区数量是双天线测量的倍数。测量根据查询老化的小区数去申请对应的资源长度，申请的长度遵循一个小区5个时隙的原则，资源的起始时间点需要遵循上一次硬件工作时刻点结束并且要在当前时刻点2slot之 后，申请资源成功后将资源起始点转化为对应的硬件工作时刻点，将对应的资源起始时间点和小区信息发送给设备层。
S2013、设备层根据小区配置信息在驱动层完成相应硬件的配置，计算UE主辅两根天线的测量参数值发送至调度层。
需要说明的是，驱动层是由设备层调用，设备层根据小区配置信息在驱动层完成相应的驱动层配置。参见图8，具体的，步骤S2013包括步骤S20131和S20132：
S20131、设备层根据小区配置信息在驱动层完成对CPICH RSCP和Ec/Io相关的硬件模块配置和数据读取。
设备层根据调度层的配置生成CPICH RSCP以及Ec/Io测量、小区预同步相关硬件的配置参数，并配置，并行工作的程序状态保存寄存器(SPSR，Saved Program Register)只支持整套配置主天线或辅天线，所以要按照需求配置。
S20132、设备层计算UE主天线和辅天线的RSSI、RSCP、Ec/Io参数测量值，选择主辅两根天线中较大Ec/Io对应的参数测量值上报至调度层。
可以理解地，响应测量的硬件中断，设备层读取硬件RAM上报的主辅双天线小区多径信息。在CPICH RSCP以及Ec/Io测量过程中，分别算出主辅两根天线的RSSI/RSCP/Ec/Io值，则根据算法方案分别计算双天线的测量结果，选取两天线中Ec/Io大的对应的RSCP结果转化为协议栈的格式，上报给调度层。在小区预同步过程中，需各自对每根天线的小区进行旁瓣抑制、径检测、同步保护等后处理，将处理之后的主天线的多径信息提供给Rake(多径接收机)，同时上报物理层L1S预同步小区的主天线最强径位置信息。
S202、UE将参数测量结果上报至RNC，获取RNC的小区切换判决结果。
参见图9，具体的，步骤S202包括步骤S2021至S2023：
S2021、调度层将接收到的UE主辅两根天线测量值经过滤波获取最终测量结果上报给RNC。
可以理解地，调度层接收到的为主辅两根天线中较大Ec/Io对应的参数测量值，调度层对该参数测量值，即主辅两根天线中较大Ec/Io对应的测量值进行滤波，将最终测量结果上报给RNC，RNC利用该最终测量结果进行小区切换判决。
S2022、UE根据主辅两根天线各自的RSSI、RSCP、Ec/Io测量值，确定上下行发送时主辅两根天线的选择。
需要说明的是，在主天线和辅天线的测量过程中，需要保存主天线和辅天线各自的RSSI、RSCP、Ec/Io测量值，根据该测量值UE选择收发效果更好的天线执行上下行信号的发送。
S2023、UE获取RNC根据最终测量结果做出的小区切换判决结果。
可以理解地，RNC做出小区切换判决结果后，UE将会根据该小区切换判决结果进行小区切换。具体地，如果测量结果已经达到门限值就触发对应的事件或读邻区的广播信道(BCH，Broadcast Channel)来触发重选和切换流程。
S203、UE根据RNC的小区切换判决结果选择驻留小区。
具体地，若RNC的小区切换判决结果为UE进行小区切换，则UE切换到信号强度更好的小区，选择该小区为驻留小区。若RNC的小区切换判决结果为UE不进行小区切换，则UE停留在原驻留小区，不进行小区切换。
本发明实施例提供了一种WCDMA系统双天线测量方法，UE使用两根天线去接收信号，每根天线独立衰落，UE计算每根天线的信号质量，取较大值上报给RNC协议栈，RNC协议栈根据测量值来评估是否要发生小区重选切换，目的是让UE驻留在信号比较好的小区，从而使业务接收达到最 优。
实施例三
参见图10，其示出了本发明实施例提供的一种WCDMA系统双天线测量方法，应用于无线网络控制器RNC，所述方法可以包括：
S301、RNC下发测量控制消息至终端UE，通知UE进行参数测量。
可以理解地，RNC通过发送“Measurement Control”消息通知UE进行参数测量。UE需要测量的参数包括RSSI、RSCP以及Ec/Io。
S302、RNC接收UE上报的参数测量结果，将参数测量结果与预设的门限值进行对比，做出小区切换判决结果。
参见图11，具体的，步骤S302包括步骤S3021和S3022：
S3021、当RNC所接收到的参数测量结果达到预设的门限值时，RNC做出小区切换判决结果，确定UE进行小区切换。
S3022、当RNC所接收到的参数测量结果未达到预设的门限值时，RNC做出小区切换判决结果，确定UE在原驻留小区不进行小区切换。
可以理解地，上述步骤S3021和S3022为RNC做出小区切换判决的具体过程，由RNC的小区切换判决决定UE驻留小区的选择。
本发明实施例提供了一种WCDMA系统双天线测量方法，UE使用两根天线去接收信号，每根天线独立衰落，UE计算每根天线的信号质量，取较大值上报给RNC协议栈，RNC协议栈根据测量值来评估是否要发生小区重选切换，目的是让UE驻留在信号比较好的小区，从而使业务接收达到最优。
