具体实施方式
以下结合附图以及实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不限定本发明。
本发明实施例的核心在于对采集数据(用户终端上报的测量信息)进行分析,最终找出开启异频测量的最佳门限,并下发给UE。
分析的主要目的在于根据UE上报的位置以及测量值,栅格化位置、找出最佳开启异频测量的区域,同时根据该区域的测量值,计算出最佳开启异频测量的时机。
目前异频组网方式大体分为三种:插花式、热点覆盖、室内外覆盖。
对于室内外覆盖和热点覆盖,这两种场景的覆盖方式可以简单的认为是基于下图1覆盖的方式,即小区A和小区B是异频邻区关系,区域1是UE从小区B到小区A前行时,从B切换到A的切换区域;而区域2是UE从小区A到小区B前行时,由A切换到B的切换区域,而区域3是UE从A到B或者从B到A开启异频测量的区域, 对于这种类型的覆盖方式,由于异频邻区只有一个,所以计算出的开启异频测量的门限也只有一个。
对于插花式覆盖,这种覆盖方式比较复杂,可以近似的认为是如图2的覆盖方式,插花布网情况下,多个小区交叉覆盖,小区A与小区B和C为异频邻区关系,B和C为同频关系,其他小区忽略,图2中标示的区域1~4的含义参见表1。
表1
Figure PCTCN2015076096-appb-000001
对于插花式覆盖,这种覆盖方式由于涉及的异频邻区有多个,因此可能计算出来的异频频点门限有多个,因此需要从多个门限值中提取出一个异频门限值,这里的提取方法包括但不限于:取最大值、最小值、平均值以及取采样点最多对应的门限值。
如图3所示,本发明实施例涉及一种异频测量门限配置方法,包括:
步骤S101,接收用户终端(UE)上报的测量信息;
本步骤中,主要是采集小区内所有用户终端(UE)的数据信息,主要采集的信息包括:
1)、UE的位置信息,例如经度和纬度;
2)、小区PCI(Physical Cell Identification,物理小区身份标识号码)–RSRP(Reference Signal Receiving Power,参考信号接收功率);
3)、同频邻区1 PCI-RSRP、同频邻区2 PCI-RSRP、同频邻区3 PCI-RSRP……;
4)、异频邻区1 PCI-RSRP、异频邻区2 PCI-RSRP、异频邻区3 PCI-RSRP……。
步骤S102,根据测量信息,判断邻区中是否存在满足设定条件的异频邻区,如果是,则根据所述测量信息确定异频测量开启门限;如果否,则将预先配置的阈值设置为异频测量开启门限;
本步骤中,设定条件是预先设置的,可以为以下条件中的任一项:
a、异频邻区的参考信号接收功率(RSRP)值大于所有同频邻区的RSRP值;
b、异频邻区的RSRP值大于预先设定的门限值O;其中,P≤O≤Q,P为同频邻区中RSRP最小值,Q为同频邻区中RSRP最大值。例如,将O设置为同频邻区中RSRP的平均值。
UE的邻区可能存在多个,即:包括多个(也可能一个)同频邻区和/或多个(也可能一个)异频邻区。以条件a为例,首选查找RSRP最大的同频邻区;然后将其与异频邻区进行比较,如果异频邻区的RSRP大,则判定邻区中RSRP最大的邻区为异频邻区,即,邻区中存在满足设定条件的异频邻区;反之,则判定邻区中RSRP最大的邻区为同频邻区,即,邻区中不存在满足设定条件的异频邻区。
步骤S103,将确定的异频测量开启门限通过第四重配消息发送给UE。
本实施例通过判断邻区中RSRP最大的邻区是否为异频邻区,如果是,则表示UE切换到异频邻区更佳,此时,通过UE上报的测量信息来确定异频测量开启门限,可以尽可能精确的配置每个小区的异频测量门限,从而达到最高程度的降低无效的异频测量,提升用户感知。
下面,以具体实例来说明本发明实施例上述方法。
步骤201,进行数据采集:
数据采集的流程如图4所示,包括如下流程:
S2011,基站下发第一重配消息,开启一个定时器(例如时长设置为120分钟),消息中携带以下信息:
1、增加一个A3事件,并设置A3事件的门限值为-3,即当邻区的RSRP高于小区RSRP-3dbm(即分贝毫)时,上报本事件;
2、增加一个A2事件,并设置A2事件的门限值为-80,即当小区RSRP低于-80dbm时,上报本事件。
S2012,UE根据基站的配置,在满足条件时,上报A3或者A2事件。基站收到上报事件后,判断UE上报的事件是否为A2事件,如果是,转步骤S2014,如果否,转步骤S2013。
S2013,当基站收到UE上报的A3事件时,记录这些上报的数据信息。此时,由于异频测量还没有开始,因此,此时上报的A3事件中包括的数据信息为:小区内每个UE的位置信息及同频邻区的RSRP。
S2014,基站收到A2事件后,再次下发第二重配消息,第二重配消息中携带以下信息:
1、删除上述的A2事件;
2、开启异频测量的命令,包括异频测量的时间,周期等。
在UE开启异频测量之后,后续再上报的A3事件,会上报异频邻区的RSRP数据,即:在上报同频邻区的RSRP数据的同时,也会将符合条件的异频邻区的RSRP数据上报,以及UE的位置信息。上报异频邻区的RSRP数据时,会按照默认设置的异频测量开启门限上报符合条件的异频邻区的RSRP。
S2015,判断是否定时器超时,或者基站存储的测量消息是否超出存储门限(例如,存储门限为100兆字节(MB))时,如果否,则返回步骤S2012;如果是,则转步骤S2016。
S2016,停止UE上报,关闭定时器,同时下发第三重配消息,并通知数据分析系统获取存储的测量信息,第三重配消息中携带以下信息:
1、删除上述的A3事件;
2、删除上述的A2事件;
3)、关闭异频测量的命令。
需要指出的是,本市实例中涉及的所有给出具体数值的相关参数都是可配置的,所有的测量信息上报都需携带位置信息。
另外,数据采集时,也可以同时采集异频邻区和同频邻区的数据,而不是采用上述实施例,只有满足A2事件时才开启异频测量的命令。如图5所示,给出本实施例的具体流程,包括:
A、基站下发第五重配消息,开启一个定时器(时长设置为120分钟),第五重配消息中携带以下信息:
1)、增加一个A3事件,并设置A3事件的门限值为-3,即当邻区的RSRP高于小区RSRP-3dbm时,上报本事件;
2)、开启异频测量的命令,包括异频测量的时间,周期等。
B、当基站收到UE上报的A3事件时,记录这些事件。
UE开启异频测量之后,上报的A3事件,上报数据包括同频邻区RSRP和异频邻区的RSRP。即:在上报同频邻区的RSRP数据的同时,也会将符合条件的异频邻区的RSRP数据上报,以及UE的位置信息。上报异频邻区的RSRP数据时,会按照默认设置的异频测量开启门限上报符合条件的异频邻区的RSRP。
C、当定时器超时,或者基站存储的测量消息超出存储门限(例如,100MB)时,关闭定时器,同时下发第三重配消息,第三重配消息中携带以下信息:
1)、删除上述的A3事件;
2)、关闭异频测量命令;
步骤202,进行数据分析:
本步骤,数据分析的单位是小区,即需要对每个小区作一次分析。分析的数据为步骤201采集的数据。UE上报的测量信息,包含以下内容:
1、位置信息:经度和纬度;
2、小区PCI–RSRP;
3、同频邻区1 PCI-RSRP、同频邻区2 PCI-RSRP、同频邻区3 PCI-RSRP、……;
4、异频邻区1 PCI-RSRP、异频邻区2 PCI-RSRP、异频邻区3 PCI-RSRP、……。
如图6所示,数据分析的具体流程如下:
S2021,根据UE上报的经、纬度信息,对小区覆盖进行栅格化,例如,栅格大小可以配置为20米(m)×20m,也可以配置为10m×10m。
S2022,根据栅格化的信息,将隶属于同一栅格的所有UE上报的测量信息进行合并,并保存;合并的方式为:
1、将同一个栅格内所有测量到的小区的RSRP累加并取均值;
2、将同一个栅格内所有测量到的具有相同PCI的同频邻区的RSRP累加并取均值;
3、将同一个栅格内所有测量到的具有相同PCI的异频邻区的RSRP累加并取均值。
保存的方式为:栅格化标识-小区RSRP-同频邻区RSRP-异频邻区RSRP。
S2023,判断是否存在异频邻区的覆盖比同频邻区的覆盖好,及判断是否有必要进行异频邻区切换,如果是,则转S2025,如果否,则转S2024。
本步骤中,判断是否存在异频邻区的覆盖比同频邻区的覆盖好,就是判断邻区中存在满足设定条件的异频邻区,当存在满足设定条件的异频邻区,则认为异频邻区的覆盖比同频邻区的覆盖好,反之,当不存在满足设定条件的异频邻区,则认为异频邻区的覆盖没有同频邻区的覆盖好。设定条件可以为以下条件中的任一项:
a、异频邻区的参考信号接收功率(RSRP)值大于所有同频邻区的RSRP值;
b、异频邻区的RSRP值大于预先设定的门限值O;其中,P≤O≤Q,P为同频邻区中RSRP最小值,Q为同频邻区中RSRP最大值。
具体判断时,以设定条件a为例(以下均以条件a为例),在小区边界的邻区中,判断是否存在RSRP值比同频邻区中RSRP最大值都大的异频邻区,如果存在,则判定异频邻区的覆盖比同频邻区的覆盖好,如果不存在,则判定异频邻区的覆盖没有同频邻区的覆盖好。
其中,边界是指小区的RSRP与最强邻区(RSRP值最大的邻区)的RSRP之差在设定范围内的区域。例如,可以将边界定位为小区RSRR和最强邻区RSRP相同的区域,也可以将边界定位为小区RSRR比最强邻区RSRP大Ndbm(或小Ndbm)的区域;N为误差参数。同时边界可能是多个栅格。
S2024,如果不存在满足设定条件的异频邻区,例如,设定条件为上述条件a时,边界最强邻区是同频邻区,则认为异频邻区的覆盖没有同频邻区好,因此不需要切换 到异频邻区,从而记录异频测量开启门限为较小值(例如-105dbm,该值预先进行配置,可以根据不同情况配置不同数值);
S2025,如果存在满足设定条件的异频邻区,例如,设定条件为上述条件a时,边界最强邻区是异频邻区,则认为异频邻区的覆盖比同频好,可以切换到异频邻区。
S2026,判断比同频邻区中RSRP最大值都大的异频邻区是否只有一个,如果是,则转S2028,如果否,则转S2027。
S2027,如果小区边界的邻区中存在满足设定条件的异频邻区、且不止一个时,则认为存在多个异频邻区,出现这种情况时处理方法包含但不限于以下几种:
异频测量开启门限为R,其中,R=Rc±Rp;Rc为小区的测量值;Rp为偏移值:通过以下任一方式确定Rc
1)、在满足设定条件的多个异频邻区中查找对应有小区边界最多的异频邻区,将小区中与该异频邻区对应的边界的RSRP值记录Rc
2)、将小区中所有边界中最大的RSRP值记录Rc
3)、将小区中所有边界中最小的RSRP值记录Rc
4)、将小区中所有边界的RSRP平均值记录Rc
S2028,当小区边界的邻区中存在满足设定条件的异频邻区、且只有一个时,则异频测量开启门限为R,其中,R=Rc±Rp;Rc为小区中与该异频邻区对应边界的RSRP;Rp为偏移值。
步骤S2027、S2028中的Rp为偏移值,可以预先配置,属于误差参数,只要保证异频测量开启门限为R在误差范围内与Rc相等即可。
步骤301,进行数据下发;
本步骤中,UE接入小区时,小区根据上述步骤分析出本小区开启异频测量的门限,将该门限值通过第四重配消息下发给UE。
数据下发主要目的是在UE接入基站时,在重配消息(第四重配消息)中携带异频测量开启门限并发送给UE。
需要说明的是:本实施例中的第一重配消息、第二重配消息、第三重配消息、第四重配消息和第五重配消息都是重配消息,只是重配消息下发的内容不同,因此,前面加上第一、第二、第三、第四和第五进行区分。

2)、增加一个A2事件,并设置UE上报A2事件的门限值;即当UE所在小区的RSRP低于该门限值时,上报A2事件。
当收到UE上报的A2事件时,向UE下发第二重配消息,第二重配消息中包括:
1)、删除上述A2事件;
2)、开启异频测量的命令。
当收到UE上报的A3事件时,记录UE上报的测量信息。

测量信息包括:UE的位置信息,以及小区的物理小区身份标识号码PCI和其参考信号接收功率(RSRP);每个同频邻区的PCI和其RSRP;以及,每个异频邻区的PCI和其RSRP。
异频测量开启门限确定单元402还设置为:
根据UE的位置信息,对小区覆盖的区域进行栅格化;
将属于同一栅格的所有UE上报的测量信息进行合并。
