Description

一种分配物理小区标识的方法及装置
本申请要求在2014年1月27日提交中国专利局、申请号为201410039004.0、申请名称为“一种分配物理小区标识的方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及无线通信技术技术领域，特别涉及一种分配物理小区标识的方法及装置。
背景技术
由于TD-LTE(Time Division Long Term Evolution，时分同步长期演进)系统中，物理小区ID(标识)与资源映射、码资源配置以及跳频等机制一一绑定，所以物理小区标识的配置同TD-SCDMA(Time Division Synchronized Code Division Multiple Access，时分同步码分多址)系统中的扰码规划作用相当，在同频组网中显得尤为重要。
物理小区标识是物理信道中扰码初始值生成的主要决定信息，特别是广播信道和控制信道，物理小区标识的相关性决定了控制信道扰码的相关性，对信道的干扰起着关键的作用。
由于物理小区标识和PSC(Primary Synchronization Code，主同步码)/SSC(Secondary Synchronization Code，辅同步码)的序列索引号一一对应，即物理小区标识和参考信号的分布有关，为了避免相邻小区产生参考信号之间的干扰，需要合理分配物理小区标识，使邻小区间的参考信号映射在不同的物理资源上，降低参考信号之间的干扰。
在实际应用中，由于物理小区标识MOD 3(模3)的余数相同的话，会造成相邻小区之间的参考信号之间的干扰较严重，因此，目前在物理小区标识分配时，主要遵循避免与相邻小区之间的MOD 3余数相同的原则。现有技 术中，为了避免与相邻小区之间的MOD 3余数相同，在进行物理小区标识分配时，根据网络拓扑结构，如根据距离、方向角、覆盖仿真重叠面等参数，判断出邻小区优先级，然后，确定出优先级较高的邻小区，保证优先级较高的邻小区的物理小区标识的MOD 3与小区的物理小区标识的MOD 3不同即可，例如，将距离最近的3个邻小区作为优先级较高的邻小区，只要保证小区与这三个邻小区的物理小区标识的MOD 3不等即可。但由于地形、建筑、发射功率等因素的影响，真正互相干扰最强的小区很可能不是距离最近的小区，这种情况下，现有的物理小区标识分配方法无法满足参考信号干扰最小(Interference-minimum)要求。
综上所述，目前分配物理小区标识的方法降低参考信号干扰的有效性较低。
发明内容
本发明实施例提供一种分配物理小区标识的方法及装置，用以提高降低参考信号干扰的有效性。
本发明实施例提供的具体技术方案如下：
一种分配物理小区标识的方法，包括：
获取与需要分配物理小区标识的待分配小区关联的每一个采样点的小区无线测量指标信息，其中所述小区无线测量指标信息用于表征小区的信号质量；
根据所述小区无线测量指标信息确定出同频干扰采样点，并根据所述干扰采样点的小区无线测量指标信息确定邻小区；
将确定出的邻小区的当前物理小区标识按照模3方式得到余数值，将余数值相同的邻小区归为一类；
根据所述小区无线测量指标信息确定每一类邻小区对所述待分配小区的干扰度，并根据最小干扰度对应的余数值对所述待分配小区进行物理小区标识的分配。
一种分配物理小区标识的装置，包括：
获取单元，用于获取与需要分配物理小区标识的待分配小区关联的每一个采样点的小区无线测量指标信息，其中所述小区无线测量指标信息用于表征小区的信号质量；
确定单元，用于根据所述小区无线测量指标信息确定出同频干扰采样点，并根据所述干扰采样点的小区无线测量指标信息确定邻小区；
分类单元，用于将确定出的邻小区的当前物理小区标识按照模3方式得到余数值，将余数值相同的邻小区归为一类；
分配单元，用于根据所述小区无线测量指标信息确定每一类邻小区对所述待分配小区的干扰度，并根据最小干扰度对应的余数值对所述待分配小区进行物理小区标识的分配。
本发明有益效果如下：
现有技术中，在分配物理小区标识时，根据网络拓扑结构确定出邻小区的优先级，并根据确定出的优先级较高的几个小区的物理小区标识，将需要进行物理小区标识分配的小区的物理小区标识进行分配，但是，根据网络拓扑结构确定出的优先级较高的邻小区可能对需要进行物理小区标识分配的小区的参考信号的影响较小，因此，降低参考信号干扰的有效性较低，而本发明实施例中，先确定出邻小区对需要进行物理小区标识分配的主小区的干扰度，再根据最小干扰度对应的余数值对主小区的物理小区标识进行分配，因此，实现了有效降低参考信号干扰，提高了降低参考信号干扰的有效性。

下面结合说明书附图对本发明优选的实施方式进行详细说明，应当理解，此处所描述的优选实施例仅用于说明和解释本发明，并不用于限定本发明，并且在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
下面结合附图对本发明优选的实施方式进行详细说明。
参阅图1所示，本发明实施例中，分配物理小区标识的详细流程如下：
步骤100：获取与需要分配物理小区标识的待分配小区关联的每一个采样点的小区无线测量指标信息，其中，小区无线测量指标信息用于表征小区的信号质量；
步骤110：根据小区无线测量指标信息确定出同频干扰采样点，并根据干扰采样点的小区无线测量指标信息确定邻小区；
步骤120：将确定出的邻小区的当前物理小区标识按照模3方式得到余数值，将余数值相同的邻小区归为一类；
步骤130：根据小区无线测量指标信息确定每一类邻小区对待分配小区的干扰度，并根据最小干扰度对应的余数值对待分配小区进行物理小区标识的 分配。
本发明实施例中，小区无线测量指标信息包括的内容有多种，例如，至少包括RSRP(Reference signal received power，参考信号接收功率)信息值、SINR(Signal to interference and noise Ratio，信干噪比)信息值；在实际应用中还可以包括其他内容，在此不再进行一一详述。
此时，根据小区无线测量指标信息确定出同频干扰采样点的方式，较佳的，可以为：
将对应的RSRP信息值未达到弱覆盖预设门限值，及SIN R信息值未达到信干噪比预设门限值的采样点，作为同频干扰采样点。
例如，与需要分配物理小区标识的小区A关联的有10个采样点，其中，采样点1、采样点2、采样点3、......、采样点10中每一个采样点均对应小区A的RSRP信息值和SINR信息值，对于每一个采样点，均判断该采样点是否为干扰采样点，具体判断方式为：查看对应的小区A的RSRP值和SINR值，在小区A的RSRP值未达到弱覆盖预设门限值，且SINR值未达到信干噪比预设门限值时，该采样点为同频干扰采样点，如最后确定采样点1、采样点2、采样点3、采样点4、采样点5为同频干扰采样点，且再根据采样点1、采样点2、采样点3、采样点4、采样点5的小区无线测量指标信息确定出邻小区为10个，然后，将确定出的10个邻小区的当前物理小区标识按照模3方式得到余数值，将余数值相同的邻小区归为一类，再计算10个邻小区中的每一个邻小区的干扰度，根据最小干扰度对应的余数值对小区A进行物理小区标识的分配。
上述只是根据小区无线测量指标信息确定出同频干扰采样点的一个实施例，在实际应用中，还存在其他多种实现方式，在此不再进行一一详述。
本发明实施例中，每一个采样点的小区无线测量指标信息中一定包括待分配小区的小区无线测量指标信息，但是，不一定包括邻小区的小区无线测量指标信息，也就是说，在包括待分配小区的小区无线测量指标信息的同时，可能包括邻小区的小区无线测量指标信息，也可能不包括。如表1所示：
表1采样点的小区无线测量指标信息
  采样点1 采样点2 采样点3 采样点4 采样点5
待分配小区的RSCP -95 -96 -96 -96 -96
主服务小区SINR 10 11 12 0 8
邻小区1的RSCP -95   -95    
邻小区2的RSCP   -95   -95  
邻小区3的RSCP       -95 -95
邻小区4的RSCP -95 -95      
邻小区5的RSCP -95     -95 -95
邻小区6的RSCP -95   -95    
邻小区7的RSCP       -95 -95
邻小区8的RSCP   -95      
邻小区9的RSCP -95 -95 -95 -95  
邻小区10的RSCP     -95   -95
邻小区11的RSCP -95       -95
邻小区12的RSCP -95   -95 -95  
......          
本发明实施例中，较佳的，弱覆盖预设门限值为-100dBm、信干噪比预设门限值为80dBm，当然，在实际应用中，还可能为其他数值，在此不再进行一一详述。
为了提高计算干扰度的效率，在根据干扰采样点的小区无线测量指标信息确定邻小区之后，将确定出的邻小区的当前物理小区标识按照模3方式得到余数值，将余数值相同的邻小区归为一类之前，还包括如下操作：确定出目标干扰邻小区，具体为；
计算每一个邻小区的第一性能属性信息值，其中，第一性能属性信息值用于表征该邻小区的接收功率强度；
将对应的第一性能属性信息值达到邻区干扰阈值的邻小区作为目标干扰邻小区。
此时，将确定出的邻小区的当前物理小区标识按照模3方式得到余数值，将余数值相同的邻小区归为一类，具体为：
将目标干扰邻小区的当前物理小区标识按照模3方式得到余数值，将余数值相同的邻小区归为一类。
例如，确定出来的邻小区有10个，则为了提高计算干扰强度的效率，先从这10个邻小区中确定出存在干扰可能的邻小区，即目标干扰邻小区，如目标干扰邻小区是5个的话，在计算干扰强度时，计算这5个目标干扰邻小区的干扰强度即可，提高了提高计算干扰强度的目的。
本发明实施例中，较佳的，第一性能属性信息值为RSRP信息值。
例如，第一邻小区的RSRP信息值-100dBm达到邻区干扰阈值-120dBm，则第一邻小区为目标干扰邻小区。
在实际应用中，还可以采用其他方式实现从邻小区中筛选出目标干扰邻小区，在此不再进行一一详述。
本发明实施例中，还需要将确定出的邻小区的当前物理小区标识按照模3方式得到余数值，将余数值相同的邻小区归为一类。
例如，有10个邻小区，邻小区1、邻小区2、邻小区3的物理小区标识除以3得到的余数值为0，则邻小区1、邻小区2、邻小区3为第一类干扰邻小区；邻小区4、邻小区5、邻小区6的物理小区标识除以3得到的余数值为1，则邻小区4、邻小区5、邻小区6为第二类干扰邻小区；邻小区7、邻小区8、邻小区9、邻小区10的物理小区标识除以3得到的余数值为2，则邻小区7、邻小区8、邻小区9、邻小区10为第三类干扰邻小区。
当然，在实际应用中，待分配的小区的邻小区的类型可以为上述三种中的一种或者任意组合，在此不再进行详述。
本发明实施例中，计算每一个邻小区的第一性能属性信息值的方式有多种，较佳的，可以为：
针对任意一邻小区，分别执行如下操作：
从全部干扰采样点对应的全部小区无线测量指标信息中筛选出与该邻小 区对应的全部第二性能属性信息值，其中，任意一与该邻小区对应的第二性能属性信息值用于表征该邻小区的接收功率强度；
将筛选出的全部第二性能属性信息值的平均值作为该邻小区的第一性能属性信息值。
例如，以表1为例，其中，采样点1-采样点5均为干扰采样点，在计算邻区1的第一性能属性信息值时，具体为计算邻区1的RSRP信息值时，由于采样点1和采样点3中包括邻区1的RSRP，因此，将采样点1和采样点3中分别包括的邻区1的RSRP信息值为-95、-95的平均值，即-95作为邻区1的RSRP信息值。表1中所示的任意一个邻小区的RSRP信息值与邻小区1的计算过程类似，在此不再进行详述。
本发明实施例中，根据小区无线测量指标信息确定每一类邻小区对待分配小区的干扰度的方式有多种，较佳的，例如采用如下方式：
针对每一类邻小区，计算该类中包括的每一个邻小区的干扰度，并将计算得到的该类中的每一个干扰小区的干扰度相加之和，作为该类干扰邻小区对待分配小区的干扰度。
例如，10个邻小区中，物理小区标识除以3得到的余数值为2的邻小区有3个，则在计算余数值为2的这种类型的邻小区的干扰度时，将包括的3个邻小区的干扰度相加，将相加得到之和作为余数值为2这类邻小区对需要分配物理小区标识的待分配小区的干扰度。
本发明实施例中，计算该类中包括的每一个邻小区的干扰度的方式有多种，较佳的，例如：
针对任意一邻小区，分别执行如下操作：
确定对应的小区无线测量指标信息中包括该邻小区的第二性能属性信息值的全部关联干扰采样点；
针对任意一关联干扰采样点，根据该关联采样点对应的小区无线测量指标信息和针对该邻小区的第二性能属性信息值计算分干扰度，其中，该关联采样点对应的小区无线测量指标信息与分干扰度呈负相关，针对该邻小区的 第二性能属性信息值与干扰度正负相关；
将计算出的所有分干扰度之和作为该邻小区的干扰度。
根据该关联采样点对应的待分配小区的小区无线测量指标信息和针对该邻小区的第二性能属性信息值计算分干扰度时，若待分配小区的小区无线测量指标信息为RSRP信息值、针对该邻小区的第二性能属性信息值也为RSRP信息值时，可以采用公式一的方式实现：
IS(i)＝1/10(RSCP_max-RSCP_i)/10    (公式一)
其中，RSCP_max为需要分配物理小区标识的待分配物理小区的RSRP值；RSCP_i为邻小区i的关联干扰采样点针对该邻小区i的RSRP；IS(i)即为邻区i对待分配小区的分干扰度。
例如，以表1所示，在计算邻小区5的干扰度时，由于采样点1、采样点4、采样点5包括邻小区5的RSRP信息值，则采样点1、采样点4、采样点5为与邻小区5关联的干扰采样点，针对采样点1、采样点4、采样点5为与邻小区5中的任意一采样点，假设采样点4，计算邻小区5对待分配小区1的分干扰度时，-95为RSCP_i，-96为RSCP_max，采用公式一进行计算出分干扰度1，同理，在计算采样点1的分干扰度2，和采样点5的分干扰度3，再将分干扰度1、干扰度2、干扰度3之和作为邻小区5对待分配小区1的干扰度。
本发明实施例中，根据最小干扰度对应的余数值对待分配小区进行物理小区标识的分配的方式有多种，较佳的，可以采用如下方式：
将最小干扰度对应的余数值作为待分配小区的物理小区标识中的PSS(Primary Synchronized Signal，主同步信号)。
例如，各类邻小区对应的干扰度如表2所示：
表2干扰度
  余数值为0 余数值为1 余数值为2
干扰度 0.387298492 2.616417793 0.217379634
从表2可以看出，物理小区标识除以2得到的干扰度最小，将需要分配物理小区标识的小区的当前物理小区标识中的PSS值该修改为2.。
由于物理小区标识＝3*Group ID(S-SS)+Sector ID(P-SS)，因此，在确定出PSS后，可以随着应用场景的不同对SSS也进行更新，在选SSS时，采用如下原则：
由于物理小区标识复用至少间隔4层小区以上，大于5倍的小区覆盖半径，那么在与需要分配物理小区标识的小区之间的距离为半径为4KM的范围内，出现过的SSS(Secondary Synchronization Signal，辅同步信号)不能选择，剩余的为候选集合，可随机选择。
为了更好地理解本发明实施例，以下给出具体应用场景，针对分配物理小区标识的过程，做出进一步详细描述，具体如图2所示
步骤200：获取与需要分配物理小区标识的待分配小区A关联的10个采样点中的每一个采样点的RSRP信息值、SINR信息值；

步骤220：根据采样点1、采样点5的RSRP信息值确定出邻小区为邻小区1-10；
步骤230：根据邻小区1至邻小区10中的每一个邻小区的RSRP信息值，确定出邻小区1、邻小区2、邻小区3为目标干扰邻小区；
步骤240：邻小区1、邻小区2、邻小区3对应的物理小区标识除以3得到的余数值分别为0、1、2，其中，余数值为1对应的干扰度最小；
