Description

上行通道分析方法、上行通道异常分析方法及其系统
技术领域
本发明涉及无线通信系统，特别涉及上行通道状况以及异常的分析技术。
背景技术
3G的三大主流无线接口标准由国际电信联盟(InternationalTelecommunications Union，简称“ITU”)在2000年确定。它们是：
宽带码分多址(Wideband Code Division Multiple Access，简称“WCDMA”)；
码分多址2000(Code Division Multiple Access 2000，简称“CDMA2000”)；
时分同步码分多址(Time Division Synchronous Code Division MultipleAccess，简称“TD-SCDMA”)。
其中，WCDMA是采用直接序列扩频(Direct Sequence Spread Spectrum，简称“DSSS”)技术的CDMA(码分多址)系统，它通过扩频码将用户带宽扩展到1000倍以上，将信道带宽扩大到5MHz。根据信息论的理论，这样可以在很低信噪比的情况下以同样的传输速率可靠地传送信息，大大增强了抗干扰能力、实现码分多址，可以支持各种不同的用户数据速率。
值得一提的是，WCDMA是世界上最早投入商用的第三代无线通信系统。
WCDMA系统由核心网(Core Net，简称“CN”)、通用移动通信系统地面无线接入网(UMTS Terrestrial Radio Access Network，简称“UTRAN”)与用户设备(User Equipment，简称“UE”)组成，并且，UTRAN与CN功能遵循尽量分离的原则，更加具体地说，对无线资源的管理功能集中在UTRAN完成，而与业务和应用相关功能则在CN执行。
由此可见，UTRAN是连接UE与CN的桥梁和纽带。
在UTRAN中，基站上行接收通道，下文中简称“上行通道”，是其重要的组成部分。它由天馈系统与基站两部分组成。其中，天馈系统是指从天线到基站射频输入端之间的设备。
基站上行通道接收到的天线口信号带宽内功率，称为宽带总接收功率(Received Total Wideband Power，简称“RTWP”)。基站负责测量RTWP的值，并向负责控制和管理UTRAN网络和无线信道的无线网络控制器报告。一般情况下，RTWP的值不但取决于接收信号本身的强度，还受到天线以及基站内部上行通道增益等众多因素的影响。
为减少快衰落对无线通信的影响，基站可以采用空间分集的方法以主、分集天线分别接收来自移动终端的信号。在下文中提及的主集的RTWP值以及分集的RTWP值，分别指上述主、分集天线接收到的来自移动终端的信号集的RTWP值。
基站的接收机对主、分集通道分别接收到的信号进行处理，一般采取最大似然法。这种主、分集接收的效果由主、分集天线接收的不相关性所保证。所谓不相关性是指，主集天线接收到的信号与分集天线的接收信号不具有同时衰减的特性，这也就要求采用空间分集时主、分集天线之间的间距大于10倍的无线信号波长(对于GSM 900M要求天线间距大于4米，1800M要求天线间距大于2米)，或者采用极化分集的办法保证主、分集天线接收到的信号不具有相同的衰减特性。
图1示出在WCDMA系统中，移动终端101的发射信号在空口和NodeB中的处理过程。首先，移动终端101的发射信号经障碍物102反射，形成多径，被NodeB的天线103接收；接着，接收信号经过射频模块104处理后，输入到基带处理模块105；然后，接收信号经过基带的解调、译码处理后，通过Iub接口输送到无线网络控制器(Radio Network Controller，简称“RNC”)106。
在实际应用中，上述方案存在以下问题：目前对于上行通道状况的检测尚未提出较为实用的方案。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明作进一步地详细描述。
如图2所示，首先，在步骤201，检测主集的RTWP值与分集的RTWP值。该步骤可以通过一个RTWP检测模块实现，在本实施例中，该模块设置在射频处理模块中。可以理解的是，RTWP检测模块也可以独立设置。
此后，进入步骤202，分别检测和计算主集与分集的多径能量及其累加值，以及主集的多径能量累加值与分集的多径能量累加值之差。该步骤可以通过一个多径能量检测模块实现，在本实施例中，该模块设置在基带处理模块中。同样可以理解，上述多径能量检测模块也可以单独设置，或设置于其它已有模块中。
需要指出的是，在本实施例中虽然先获取主集的RTWP值与分集的RTWP值，再获取主集与分集的多径能量及其累加值，以及主集的多径能量累加值与分集的多径能量累加值之差，但是两个步骤的顺序可以调换，而并不影响本发明的效果。
此后进入步骤203，根据获取的值，判断是否满足预先设置的上行通道异常判断条件。
具体的说，在本发明的上行通道异常判断条件中，如果主集的RTWP值小于预定第一门限，或分集的RTWP值小于预定第二门限，或者主集的RTWP值与分集的RTWP值之差大于预定第三门限时，则判定上行通道异常，因此在满足上述判断条件时，进入步骤204，上报上行通道异常。
此外，在上行通道判断条件中，当所述主集的多径能量累加值与分集的多径能量累加值之差高于第四门限时，也判定上行通道异常，因此满足该条件的，也上报上行通道异常。
更具体地说，在本发明中还对上行通道异常原因的判定提出了详细的判断依据。一般来说，上行通道异常的原因分为外界干扰、分集接收通道故障以及主集接收通道故障。
在本发明中，如果满足以下条件，则系统将上行通道异常的原因判定为主集接收通道故障：
主集的RTWP值小于第一门限时，或
主集的RTWP值与分集的RTWP值之差大于第三门限，且分集的RTWP值大于主集的RTWP值，并且主集多径能量累加值与分集多径能量累加值之差大于第四门限，且主集多径能量累加值小于分集多径能量累加值时，或
主集的RTWP值与分集的RTWP值无异常，并且主集多径能量累加值与分集多径能量累加值之差大于第四门限，且主集多径能量累加值小于分集多径能量累加值。
如果满足以下条件，则系统将上行通道异常的原因判定为分集接收通道故障：
分集的RTWP值小于第二门限，或
主集的RTWP值与分集的RTWP值之差大于第三门限，且主集的RTWP值大于分集的RTWP值，并且主集多径能量累加值与分集多径能量累加值之差大于第四门限，且分集多径能量累加值小于主集多径能量累加值，或
主集的RTWP值与分集的RTWP值无异常，并且主集多径能量累加值与分集多径能量累加值之差大于第四门限，且分集多径能量累加值小于主集多径能量累加值。
如果满足以下条件，则系统将上行通道异常的原因判定为外界干扰。
主集的RTWP值与分集的RTWP值之差大于第三门限，且主集的RTWP值大于分集的RTWP值，并且主集多径能量累加值与分集多径能量累加值之差大于第四门限，且主集多径能量累加值小于分集多径能量累加值，或
主集的RTWP值与分集的RTWP值之差大于第三门限，且分集的RTWP值大于主集的RTWP值，并且主集多径能量累加值与分集多径能量累加值之差大于第四门限，且分集多径能量累加值小于主集多径能量累加值。
通过上述实施例，采用RTWP，以及基带处理中得到的多径能量累加和进行上行通道的联合状况检测与分析机制，并提出了采用RTWP和基带处理中用到的多径能量累加和进行联合异常原因检测分析的具体判断标准，有效地实现了WCDMA系统中的上行通道状况以及异常原因的检测与分析，从而增强基站的可分析与可维护性。
以上描述了根据本发明的第一实施例的WCDMA系统中的上行通道异常的分析方法，接下来描述根据本发明的第二实施例的WCDMA系统中的上行通道异常的分析系统。
如图3所示，第二实施例的WCDMA系统中的上行通道异常的分析系统包含设置在射频处理模块304内的RTWP检测模块、设置在基带处理模块305内的多径能量检测模块，以及判断逻辑处理模块306。
RTWP检测模块检测主集的RTWP值与分集的RTWP值，并将检测到的值发送给判断逻辑模块306。和第一实施例相同，该RTWP检测模块可以如本实施例般地设置在射频处理模块304中，也可以单独设置。
多径能量检测模块分别检测和计算主集与分集的多径能量及其累加值，以及主集的多径能量累加值与分集的多径能量累加值之差，并将结果发送给判断逻辑处理模块306。虽然本实施例中将模块设置在基带处理模块305中，但在本发明的其它实施例中，将该模块独立设置，或者设置于判断逻辑处理模块306中，都不影响本发明的效果。
判断逻辑处理模块306根据接收到的值，依据预先设定的上行通道异常判断条件进行判断，当满足该条件时，则上报上行通道异常。
具体地说，判断逻辑处理模块306分别比较主集的RTWP值与预定第一门限，分集的RTWP值与预定第二门限，以及主集的RTWP值与分集的RTWP值之差与预定第三门限，当所述主集的RTWP值小于预定第一门限，或分集的RTWP值小于预定第二门限，或者主集的RTWP值与分集的RTWP值之差大于预定第三门限时，
则判断逻辑处理模块306上报异常。
除此之外，判断逻辑处理模块306还比较所述主集的多径能量累加值与分集的多径能量累加值之差，与预定第四门限，当所述主集的多径能量累加值与分集的多径能量累加值之差高于第四门限时，也满足上行通道异常判断条件，故判断逻辑处理模块306也将上报上行通道异常。
在本实施例中，也进一步对上行通道异常的原因分析提供了详细的标准，将所述原因分为主集接收通道故障、分集接收通道故障以及外界干扰。该标准基本与第一实施例的标准一致。为了使该标准更加清楚易懂，可参见表1。

判定上行通道异常原因为外界干扰。
在第二实施例中，上行通道异常的分析系统中分别包含有设置在射频处理模块304中的RTWP检测模块、设置在基带处理模块305内的多径能量检测模块，以及判断逻辑处理模块306，并通过检测到的RTWP，以及多径能量累加和，进行上行通道的联合状况检测，对于满足上行通道异常判断条件的情况输出上行通道异常。并且，本实施例也提出了RTWP和基带处理中用到的多径能量累加和实现联合异常原因检测分析的具体判断标准，据此可进一步明确上行通道异常的原因，从而有效地实现了WCDMA系统中的上行通道状况以及异常原因的检测与分析，增强基站的可分析与可维护性。
下面描述根据本发明的第三实施例的无线通信系统中上行通道的分析方法。
如图4所示，首先，在步骤401，检测主集的RTWP值与分集的RTWP值。该步骤可以通过一个RTWP检测模块实现，在本实施例中，该模块设置在射频处理模块中。如上所述，RTWP检测模块也可以独立设置。
此后，进入步骤402，分别检测和计算主集与分集的多径能量及其累加值，以及主集的多径能量累加值与分集的多径能量累加值之差。该步骤可以通过一个多径能量检测模块实现，在本实施例中，该模块设置在基带处理模块中。如上所述，多径能量检测模块也可以单独设置，或设置于其它已有模块中。
需要指出的是，在本实施例中虽然先获取主集的RTWP值与分集的RTWP值，再获取主集与分集的多径能量及其累加值，以及主集的多径能量累加值与分集的多径能量累加值之差，但是两个步骤的顺序可以调换，而并不影响本发明的效果。
此后进入步骤403，根据获取的值，判断是否满足预先设置的上行通道正常的判断条件。
具体的说，在本发明的上行通道异常判断条件中，如果主集的RTWP值大于预定第一门限，且分集的RTWP值大于预定第二门限，且主集的RTWP值与分集的RTWP值之差小于预定第三门限，则主集与分集的RTWP正常；另一方面，如果主集的多径能量累加值与分集的多径能量累加值之差低于第四门限，则属于正常。因此在满足上述判断条件时，进入步骤404，上报上行通道正常。否则，进入步骤405，上报上行通道异常。
通过上述实施例，采用RTWP，以及基带处理中得到的多径能量累加和进行上行通道的联合正常检测，有效地实现了WCDMA系统中的上行通道的状况分析，从而增强基站的可分析与可维护性。
虽然上述实施例以WCDMA系统为例，但熟悉本领域的技术人员可以理解，本发明还可以应用于其它无线通信系统中，例如码分多址通信系统、或码分多址2000通信系统、或时分同步码分多址通信系统、或全球移动通信系统等等。
虽然通过参照本发明的某些优选实施方式，已经对本发明进行了图示和描述，但本领域的普通技术人员应该明白，可以在形式上和细节上对其作各种改变，而不偏离本发明的精神和范围。
