Description

LTE通信系统及其小区测量方法、UE及基站、存储介质 技术领域
本发明涉及通信领域，具体涉及一种LTE通信系统及其小区测量方法、UE(用户终端)及基站、存储介质。
背景技术
LTE系统中测量连接状态下(RRC_CONNECTED)的移动性测量，即在RRC_CONNECTED状态下，E_UTRAN(Evolved Universal Terrestrial Radio Access Network：演进型的统一陆地无线接入网络)通过专属信令向UE下发测量配置(measurement configuration)信息，该测量配置信息具体在RRC Connection Reconfiguration消息携带。UE对测量报告的上报可以是事件触发也可以使周期性触发，当满足测量报告条件时，UE将测量结果填入测量报告(Measurement Report)中，发给基站(Evolved NodeB，演进型基站，简称基站)。
目前LTE系统内的测量报告(包括同频和异频)，只报告了本小区和邻小区的RSRP(Reference Signal Receiving Power，参考信号接收功率)和RSRQ(Reference Signal Receiving Quality，参考信号接收质量)，RSRP只能映本小区和邻小区导频信号(Reference Signal：RS)信号的强度，RSRQ只能反映本小区的信号强度，负荷和干扰，而实际中真正能反映信号质量是导频信号的SINR(Signal to Interference plus Noise Ratio，SINR，表达方式：SINR＝Signal/(Interference+Noise))，但是从RSRQ和RSRP又很难推算出SINR这个参数。所以目前基于测量报告只能进行一些基本网络的覆盖情况的推断，包括弱覆盖、过覆盖、漏配邻区等，但对于提高网络性能来言远远不够。因为基于测量报告由于无法得到下行的SINR数据而成为性能 分析过程的瓶颈。
发明内容

具体实施方式
下面通过具体实施方式结合附图对本发明作进一步详细说明。
实施例一
本实施例提供的LTE系统的小区测量方法，用户终端可以对其所在服务小区导频信号的SINR进行测量并上报给基站，以为后续系统性能的分析提供更好的依据。其实现过程为:
在用户终端侧，请参见图1所示，包括：
步骤101：用户终端对其当前所在服务小区的导频信号的SINR进行测量；
步骤102：用户终端在上报条件触发时，向服务小区的基站上报服务小 区导频信号的SINR测量结果。
在基站侧，请参见图2所示，包括：
步骤201：基站接收用户终端在上报条件触发时上报的SINR测量结果；
步骤202：基站基于SINR测量结果进行后续分析等处理。
应当理解的是，本实施例中用户终端还可同时向基站上报RSRP和/或RSRQ。
上述步骤102中用户终端可以直接将得到的服务小区导频信号的SINR测量结果发送给基站。此时的上报条件可以由用户或者运营商自行设定，例如设定为用户终端空闲时、用户终端充电时或者周期性上报等等。且本实施例中用户终端上报服务小区导频信号的SINR测量结果所消耗的流量可不计费。
上述步骤102中，用户终端可以通过将服务小区导频信号的SINR测量结果携带在测量报告中上报给基站。此时的上报条件为测量报告上报条件，其触发可以是事件触发，也可以是周期性触发。具体采用哪种触发机制可以根据具体的应用场景选定。下面以用户终端通过将服务小区导频信号的SINR测量结果携带在测量报告中上报给基站的方式对本发明做进一步说明。
本实施例中，用户终端在对其当前所在服务小区的导频信号的SINR进行测量之前，还可与基站先进行协商，用户终端告知基站用户终端会对其当前的服务小区的SINR进行测量并上报；或基站告知用户终端需对其当前所在服务小区的SINR进行测量并上报；具体的，基站可以通过在下发的测量配置消息中告知用户终端需对在服务小区的SINR进行测量。本实施例中的测量配置消息具体可包括测量对象(需对哪些指标进行测量，在该测量对象中可包含SINR)、报告配置、测量标识、数量配置、服务小区质量门限控制、移动性状态检测等。用户终端收到测量配置消息后可根据该测量 配置消息进行相应的配置测量。本实施例中的测量配置消息具体也可采用RRC Connection Reconfiguration(RRC连接重配置)消息发送。
本实施例中，用户终端通过测量报告向基站上报SINR的结果可采用以下两种方式中的任意一种，但应当理解的是并不局限于以下两种方式。这两种方式只是作为本发明的示例性说明。
方式一：通过在测量报告中扩展专用字段实现：
对于这种方式，用户终端在测量报告中增加扩张字段以用于放置SINR测量结果。对于扩张的字段需进行定义，定义为用户终端需上报的导频信号的SINR测量结果。
对于专用字段的扩展，用户终端与基站之间也需先协商好，基站后续收到扩展后的测量报告后才能正确的从中提取出SINR测量结果。本实施例中，基站可以通过其下发的测量配置消息完成该协商，具体的：基站可在用户终端对其当前所在服务小区的导频信号的SINR进行测量之前，向其下发的测量配置消息，该测量配置消息中包含用于放置SINR测量结果的扩展字段指示；用户终端根据扩展字段指示在测量报告中扩展相应的字段，将SINR测量结果放置在该扩展字段中后上报给基站。
方式二：通过在测量报告中的邻区测量报告列表中添加实现：
测量报告包括邻区测量报告列表，用户终端在该邻区测量报告列表中添加各对各邻区的测量结果。本实施例中用户终端将其当前所在的服务小区也作为一个虚拟邻区添加到邻区测量报告列表中，并添加对应的SINR测量结果后发给基站。具体的，用户终端将服务小区的标识信息(例如服务小区的物理小区ID)添加到邻区测量报告列表中并对应添加SINR测量结果。这样基站接收到测量报告后，可以从测量报告的邻区测量报告列表中读取到服务小区的标识信息，根据该标识信息可以判断出实际为基站本身的小区(也即读取的为虚拟邻区)并进而可以读取到SINR测量结果。
本实施例中用户终端具体可以将SINR测量结果添加到邻区测量报告列表的最后一项中，也可以放置在中间或第一项等。应当理解的是本实施例对其在邻区测量报告列表的具体放置位置并无限制，只要基站能从中读取并识别出即可。
对于方式二，用户终端对测量报告的结构不需要做任何改变，只需要在原有测量报告基础上增加一项新的内容(即SINR测量结果)即可。基站在收到后根据小区的标识信息即可识别读取到服务小区的SINR测量结果。
请参见图3所示，上述LTE系统中的小区测量方法的总流程包括：
步骤301：用户终端对其当前所在服务小区的导频信号的SINR进行测量；
步骤302：用户终端在测量报告上报条件触发时，向服务小区的基站上报测量报告，测量报告包含服务小区导频信号的SINR测量结果；上报方式可以采用上述两种方式中的任意一种；
步骤303：基站接收用户终端上报的测量报告；
步骤304：基站从接收到的测量报告中提取出服务小区导频信号的SINR测量结果。
SINR参数对于基站调度，网络优化，网络检测，干扰排查具有重要的意义，具体如下：
基站调度：用户终端下行的数据调度目前是通过终端用户上报CQI信息来选择相应的MCS，如果结合终端用户上报的SINR，则可以更精细的对用户进行合理的调度，同时也可以通过不同终端上报SINR和CQI的差异分析来定位终端问题。
网络优化：RSRP和SINR的上报可以反映的真实网络信号强度和质量，为网络优化提供了数据基础。
网络监控：通过搜集RSRP和SINR，并统计分析，能够周期性的监控 网络运行状况的变化。
干扰排查：通过对SINR的统计监控分析，可以监控系统干扰的变化和位置，结合地理信息系统，可以排查干扰的方向，为定位干扰源，以及基站间，小区间的协调调度，ICIC提供算法依据。
本实施例中的SINR测量结果的取值范围请参见表1所示：
表1
Figure PCTCN2015075904-appb-000001
基站在接收到测量报告后，根据从中提取的SINR测量结果以及上述表1的对应关系，即可获取到实际的SINR。

方式一：通过在测量报告中扩展专用字段实现：
对于这种方式，用户终端1在测量报告中增加扩张字段以用于放置SINR测量结果。对于扩张的字段需进行定义，定义为用户终端需上报的导频信号的SINR测量结果。对于专用字段的扩展，用户终端1与基站2之间也需先协商好，基站2后续收到扩展后的测量报告后才能正确的从中提取出SINR测量结果。本实施例中，基站2可以通过其下发的测量配置消息完 成该协商，具体的：
请参见图7所示，第一发送模块12包括测量报告发送子模块时，用户终端1还包括第一接收模块13；请参见图8所示，对应的，基站还包括第二发送模块23，配置为在基站接收用户终端上报的测量报告之前：向用户终端下发测量配置消息，该测量配置消息中包含用于放置SINR测量结果的扩展字段指示。用户终端1的第一接收模块13，配置为在测量模块11对其当前所在服务小区的导频信号的SINR进行测量之前，接收基站2下发的测量配置消息，该测量配置消息中包含用于放置SINR测量结果的扩展字段指示；第一发送模块12的测量报告发送子模块根据扩展字段指示在测量报告中扩展相应的字段，将SINR测量结果放置在该扩展字段中后上报给基站。
