Definitions

  • the present invention relates to the field of communications technologies, and in particular, to an interference coordination method and device.
  • Spectrum resources are the basis of the operator's operating network. Its scarcity determines that the spectrum is an invaluable resource.
  • 3G third-generation mobile communication technology
  • 4G fourth generation mobile communication technology
  • the refarming refers to re-planning the spectrum. For example, it usually refers to the use of the spectrum used by the low-standard system for a high-standard system to improve the spectrum utilization efficiency without increasing the spectrum resources.

  • the primary problem to be solved is the interference problem between the GSM system and the LTE system.
  • the industry often reduces the interference between the GSM system and the LTE system by placing the GSM spectrum and the LTE spectrum at both ends of the spectrum, or by spatial isolation. That is to say, when deploying the GL Refarming solution, for the area where LTE has been deployed, GSM can only use the spectrum that LTE does not occupy. Otherwise, the performance of GSM and LTE may be poor due to the same frequency interference; or, by geographical location A certain isolation distance is reserved to enable GSM to use the spectrum used by LTE.
  • GSM can only use the FB2 frequency different from FB1; accordingly,
  • a certain same-frequency isolation band can be reserved in the geographical position, such as area B, and in the area B which is the same-frequency isolation band, GSM can only use FB2.
  • Frequency further, by the protection of the same frequency isolation band, at the location C, GSM can use the frequencies FB1 and FB2.
  • the LTE bandwidth that can be deployed needs to be limited by the original GSM traffic load. Because GSM has a high traffic load in certain areas and cannot exit more spectrum, Only LTE with small bandwidth (such as 5MHz) can be deployed. The throughput advantage of deploying large-bandwidth LTE cannot be obtained. If you want to deploy LTE with large bandwidth, you can only purchase additional spectrum. In addition, in areas where LTE is deployed and in the same-frequency isochronous zone around LTE, GSM can only use unused frequencies of LTE, resulting in lower spectrum utilization and a significant reduction in GSM available spectrum, resulting in GSM network capacity and Loss of performance.
  • the industry proposes a corresponding LTE compression bandwidth scheme, which can compress LTE standard bandwidth by using advanced filter technology and scheduling algorithm, such as compressing 20M LTE standard bandwidth to 18M through compression bandwidth technology, and compressing 2M spectrum. It can be used to deploy GSM to achieve the purpose of deploying more bandwidth LTE on the existing GSM spectrum while satisfying the capacity and performance of the GSM original network.

Description

一种干扰协调方法及设备 技术领域
本发明涉及通信技术领域，尤其涉及一种干扰协调方法及设备。
背景技术
频谱资源是运营商运营网络的基础，其稀缺性决定了频谱是非常宝贵的资源，而且，随着移动宽带的不断发展以及3G(第三代移动通信技术)、4G(第四代移动通信技术)网络的不断演进，运营商对频谱效率的提升的需求越发强烈。在此基础上，为了提高频谱利用率，运营商提出了Refarming(频谱重分配)技术。所述Refarming是指对频谱进行重规划，如通常是指将低制式系统所使用的频谱让出一段来给高制式系统使用，以在不增加频谱资源的情况下，达到提高频谱利用效率的目的。具体地，以GL Refarming(GSM&LTE Refarming)为例，其即指的是将GSM(Global System for Mobile Communication，全球移动通信网络)频谱让出一段给LTE(Long Term Evolution，长期演进)使用。
具体地，在部署GL Refarming方案时，首要解决的问题是GSM系统和LTE系统之间的干扰问题。目前，业界常通过将GSM频谱和LTE频谱分别放在频谱的两端，或者通过空间隔离来降低GSM系统和LTE系统之间的干扰。也就是说，在部署GL Refarming方案时，对于已经部署LTE的区域，GSM只能使用LTE不占用的频谱，否则会由于GSM和LTE相互同频干扰导致性能差；或者，可通过在地理位置上预留一定的隔离距离，以使得GSM能够使用LTE所使用的频谱。
例如，如图1所示，假设区域A部署有LTE站点，且该LTE站点所使用的频率为FB1，则在该区域A位置处，GSM只能使用不同于FB1的FB2频率；相应地，为了避免GSM和LTE的同频干扰问题，可在地理位置上预留一定的同频隔离带，如区域B，并且，在作为同频隔离带的区域B，GSM也只能使用FB2 频率；进一步地，通过同频隔离带的保护，在区域C位置处，GSM则可使用频率FB1和FB2。
由上述内容可知，目前，在部署GL Refarming方案时，能够部署的LTE带宽需受限于原网GSM话务负荷，由于GSM在某些区域的话务负荷较高、无法退出更多频谱，导致只能部署小带宽(如5MHz)的LTE，无法获取部署大带宽LTE所带来的吞吐率优势，若希望部署大带宽的LTE则只能另购频谱。另外，在部署有LTE的区域以及LTE周围同频隔离带区域，GSM只能使用LTE未使用的频率，从而导致频谱利用率较低，同时由于GSM可用频谱大幅缩减，还会导致GSM网络容量和性能的损失。
针对上述问题，业界提出了相应的LTE压缩带宽方案，即可利用先进滤波器技术和调度算法等压缩LTE标准带宽，如将20M的LTE标准带宽通过压缩带宽技术压缩到18M，压缩出来的2M频谱可用于部署GSM，以在满足GSM原网容量和性能的前提下，达到在已有GSM频谱上部署更大带宽的LTE的目的。
但是，由于压缩带宽技术所压缩的频谱十分有限，使得对于大部分场景来说，仍无法满足原网GSM容量和性能要求，同时也无法在已有GSM频谱上部署更大带宽的LTE，若希望部署大带宽的LTE则只能另购频谱。另外，在同一地理区域，GSM和LTE只能邻频部署，即在频域上要么GSM使用、要么LTE使用，否则会导致GSM和LTE之间存在严重的同频干扰，因此，仍会存在频谱利用率较低等问题。
发明内容
本发明实施例提供了一种干扰协调方法及设备，以解决目前存在的进行GL Refarming部署时无法部署更大带宽的LTE以及频谱利用率较低等问题。

所述请求接收单元22可用于接收位于第一小区的任一区域内的终端发起 的干扰协调请求，所述干扰协调请求是所述终端在使用任一待使用频谱资源之前，向网络侧协调设备发起的；需要说明的是，在本发明所述实施例中，第一小区内的终端待使用的任一频谱资源通常可指的是与第二小区配置的各频谱资源同频的频谱资源中的任一频谱资源，本发明实施例对此不作赘述。当然需要说明的是，第一小区内的终端待使用的任一频谱资源也可指的是与第二小区配置的各频谱资源不同频的频谱资源中的任一频谱资源，本发明实施例对此不作任何限定。
所述状态获取单元23可用于获取各第二小区的频谱资源实时占用状态；具体地，所述状态获取单元23可用于通过向各第二小区的控制设备下发频谱资源状态获取指令并接收各第二小区的控制设备返回的携带有相应频谱资源实时占用状态信息的响应消息的方式获取各第二小区的频谱资源实时占用状态，或者，可用于通过接收各第二小区的控制设备主动上报的各第二小区的频谱资源实时占用状态信息的方式，获取各第二小区的频谱资源实时占用状态，本发明实施例对此不作任何限定。其中，所述第二小区的控制设备可为所述第二小区的服务基站等设备，本发明实施例对此不作赘述。
所述干扰协调单元24可用于在接收到位于第一小区的任一区域内的终端发起的干扰协调请求的同时或之后，根据所述矩阵构建单元21预先构建的用于表征各第二小区相对所述第一小区中的各区域的历史参考干扰大小的干扰矩阵，以及所述状态获取单元23获取到的各第二小区的频谱资源实时占用状态，确定所述终端待使用的所述任一待使用频谱资源所受到的来自各第二小区的实际干扰大小的叠加值，并判断确定的所述实际干扰大小的叠加值是否不超出预设的干扰门限取值范围，若是，则触发指示发送单元25向所述终端下发第一调度指示，若否，则触发指示发送单元25向所述终端下发第二调度指示。

具体地，由于无论是GSM系统还是LTE系统，小区下用户的话务分布特征是相对固定的，且具有一定的周期性，并且系统内小区站点的位置、发射功率等也都是相对固定的。因此，可利用GSM系统或LTE系统内各终端上报的测量信息获取小区的话务模型数据，进而根据获取的测量信息或话务模型数据构造能够表征GSM系统和LTE系统之间干扰关系的干扰矩阵。
具体地，在本发明所述实施例中，以用于表征各第二小区相对所述第一小区中的各区域的历史参考干扰大小的干扰矩阵为例，所述用于表征各第二小区相对所述第一小区中的各区域的历史参考干扰大小的干扰矩阵可是所述矩阵构建单元21基于预先统计的设定时间段内的第一小区内的各终端上报的测量信息构建的。其中，所述测量信息具体可包括第一小区内的各终端接收到来自各第二小区的信号的信号强度、第一小区内的各终端接收到来自各第二小区的信号的信号质量、各第二小区与第一小区内的各终端所在位置之间的距离、各第二小区发射的信号到第一小区内的各终端所在位置的信号损耗中的任意一种或多种，本发明实施例对此不作任何限定。另外需要说明的是，所述用于表征各第二小区相对所述第一小区中的各区域的历史参考干扰大小的干扰矩阵也可以是所述矩阵构建单元21基于与第一小区共站同覆盖的第二小区内的各终端上报的测量信息所构建的，本发明实施例对此也不作任何限定。
进一步地，仍以用于表征各第二小区相对所述第一小区中的各区域的历史参考干扰大小的干扰矩阵为例，所述矩阵构建单元21具体可用于通过以下步骤基于预先统计的设定时间段内的第一小区内的各终端上报的测量信息构建用于表征各第二小区相对所述第一小区中的各区域的历史参考干扰大小的干扰矩阵：
步骤S1：根据设定的区域划分规则，将所述第一小区的小区覆盖范围划分为N个子区域，所述N为任意自然数；具体地，可根据第一小区的小区覆盖范围内的各区域距离第一小区的服务基站的距离、第一小区的小区覆盖范围 内的各区域接收到第一小区的服务基站的信号强度、第一小区的小区覆盖范围内的各区域接收到第一小区的服务基站的信号质量以及第一小区的服务基站到第一小区的小区覆盖范围内的各区域的路损等，将所述第一小区的小区覆盖范围划分为N个子区域，本发明实施例对此不作任何限定；需要说明的是，优选地，所述N通常可为大于1的自然数，本发明实施例对此不作赘述。
步骤S2：针对任一子区域，根据设定时间段内收集到的第一小区内的各终端上报的测量信息(具体可为设定时间段内收集到的位于所述任一子区域内的各终端上报的测量信息)，确定各第二小区所配置的各频谱资源相对所述任一子区域的历史参考干扰大小，并根据确定的各第二小区所配置的各频谱资源相对所述任一子区域的历史参考干扰大小，生成所述任一子区域对应的干扰子矩阵。
其中，各第二小区相对所述第一小区中的各区域的历史参考干扰大小的表示方式至少可以包括：各第二小区发射的信号到达所述第一小区中的各区域时的信号强度、各第二小区发射的信号到达所述第一小区中的各区域时的信号质量、各第二小区与所述第一小区中的各区域之间的距离、各第二小区发射的信号到所述第一小区中的各区域时的信号损耗中的任意一种或多种，本发明实施例对此不作任何限定。
步骤S3：将确定的各子区域对应的干扰子矩阵所形成的干扰子矩阵集合作为构建的用于表征各第二小区相对所述第一小区中的各区域的历史参考干扰大小的干扰矩阵。
例如，如图3所示，可将CELL1(即第一小区)的小区覆盖范围划分为子区域1、子区域2、...、子区域N，并收集CELL1在子区域1和邻区CELL2、CELL3、...、CELLK(所述CELL2、CELL3、...、CELLK均为第二小区，且所述K的取值为大于等于1的任意自然数)之间的干扰关系数据，CELL1在子区域2和邻区CELL2、CELL3、...、CELLK之间的干扰关系数据，.....，CELL1在子区域N和邻区CELL2、CELL3、...、CELLK之间干扰关系数据，以形成不同位置小区间的干扰矩阵。其中，每个子区域对应的的干扰子矩阵可反应 了在该子区域下邻区CELL2、CELL3、....、CELLK对CELL1的干扰影响，其中，所述干扰影响的表示方式可以是质量、距离、电平或者路损等。一个小区覆盖范围内所有划分的子区域对应的干扰子矩阵的集合就组成这个小区的干扰矩阵。依次类推，每个小区都可以按照上述干扰矩阵确定方式确定出用于表征周围各邻区相对所述小区中的各区域的历史参考干扰大小的干扰矩阵，本发明实施例对此不作赘述。
进一步地，需要说明的是，在本发明所述实施例中，在预先构建干扰矩阵之后，所述矩阵构建单元21还可实时或定时收集第一小区内的各终端上报的测量信息(或与第一小区共站同覆盖的第二小区内的各终端上报的测量信息)，并基于实时或定时收集到的第一小区内的各终端上报的测量信息(或与第一小区共站同覆盖的第二小区内的各终端上报的测量信息)对预先构建的干扰矩阵进行更新，本发明实施例对此不作赘述。例如，针对采用SON(Self-Organizing Network，自组织网络)架构的系统，该系统即可不断自动收集并刷新小区中的干扰矩阵数据，以达到对小区中的干扰矩阵数据进行实时或定时更新的目的。
另外需要说明的是，在本发明所述实施例中，所述矩阵构建单元21除了可基于现网的测量信息构造干扰矩阵之外，还可使用仿真工具进行电平覆盖预测、以模拟现网的拓扑结构以及信号发射特点，并基于相应的仿真结果来构造干扰矩阵，本发明实施例对此不作赘述。
进一步地，仍以用于表征各第二小区相对所述第一小区中的各区域的历史参考干扰大小的干扰矩阵为例，在得到上述干扰矩阵之后，即可根据相应的干扰矩阵以及获取到的各第二小区的频谱资源实时占用状态，确定位于所述第一小区的任一区域内的终端待使用的任一频谱资源所受到的来自各第二小区的实际干扰大小的叠加值。
具体地，以所述第一小区为LTE系统下的任一小区，所述第二小区为GSM系统下的任一小区为例，所述干扰协调单元24具体可用于通过以下方式来根据构建的用于表征各第二小区相对所述第一小区中的各区域的历史参考干扰 大小的干扰矩阵以及各第二小区的频谱资源实时占用状态，确定位于所述第一小区的任一区域内的终端待使用的任一频谱资源所受到的来自各第二小区的实际干扰大小的叠加值：
确定各第二小区的频谱资源实时占用状态S，其中，所述频谱资源实时占用状态S可如下式所示：
S＝{CELL_1(X0,X1,...,Xi),CELL_2(X0,X1,...,Xi),...CELL_n(X0,X1,...,Xi)}；其中，n为第二小区的数量且所述n为任意自然数；i表示各第二小区所配置的频谱资源的数量且所述i为任意自然数；Xi代表各第二小区所配置的第i个频谱资源的实时占用状态，其中，所述Xi的取值为1表示频谱资源被占用、取值为0表示频谱资源被释放；并
根据所述干扰矩阵，确定在所述任一区域，所述终端所受到的来自第n个第二小区所配置的各频谱资源的历史参考干扰大小In，所述In可如下式所示：
In＝CELL_n(Y0，Y1，...，Yi)；其中，CELL_n(Yi)表示在所述任一区域，所述终端所受到的来自第n个第二小区所配置的第i个频谱资源的历史参考干扰大小；以及，
通过以下公式确定在所述任一区域，所述终端待使用的任一频谱资源所受到的来自各第二小区所配置的各频谱资源的实际干扰大小的叠加值I总：
I总＝CELL_1(X0*Y0*θ0+X1*Y1*θ1+...+Xi*Yi*θi)+CELL_2(X0*Y0*θ0+X1*Y1*θ1+...+Xi*Yi*θi)+...+CELL_n(X0*Y0*θ0+X1*Y1*θ1+...+Xi*Yi*θi)；其中，θ表示各频谱资源的干扰权重修正值；CELL_n(Xi*Yi)表示在所述任一区域，所述终端待使用的所述任一频谱资源所受到的来自第n个第二小区所配置的第i个频谱资源的实际干扰大小。具体地，与各第二小区所配置的各频谱资源相对应的干扰权重修正值通常可是根据历史收集数据样本中不同干扰小区、每个小区中不同干扰频点的干扰大小相对于实际干扰大小的预测误差所确定的，以用于根据实际情况对干扰大小进行相应修正，以使得最终计算得到的干扰大小趋近于事实上的实际干扰大小。
由上述内容可知，为了能准确评估第一小区中的某个位置处的终端受到 的来自各第二小区的干扰状况，需考虑各第二小区实际所使用的资源。具体地，对于GSM小区来说，GSM小区配置的载频上有用户占用时和无用户占用时产生的干扰不同，载频上有一个用户和多个用户占用时产生的干扰也不同，且GSM小区配置的多个载频同时被占用时需要考虑总的干扰功率叠加。类似地，LTE的带宽内包含多个RB资源，LTE使用的RB资源不同对于GSM的干扰也是不同。因此，在计算GSM系统中的各GSM小区对LTE系统中的各LTE小区的干扰时，需要获知各GSM小区占用的载频以及每个载频上占用用户等情况；相应地，在计算LTE系统中的各LTE小区对GSM系统中的各GSM小区的干扰时，则需要获知各LTE小区的RB占用情况。
进一步地，所述干扰协调单元24在确定所述终端待使用的所述任一待使用频谱资源所受到的来自各第二小区的实际干扰大小的叠加值之后，即可执行判断确定的所述实际干扰大小的叠加值是否不超出预设的干扰门限取值范围的操作。
具体地，在本发明所述实施例中，判断确定的所述实际干扰大小的叠加值是否不超出预设的干扰门限取值范围，通常可以是指：判断确定的所述实际干扰大小的叠加值是否位于所述预设的干扰门限取值范围所限定的数值区间内。
例如，当各第二小区相对所述第一小区中的各区域的历史参考干扰大小或实际干扰大小的表示方式为各第二小区发射的信号到达所述第一小区中的各区域时的信号强度、或各第二小区发射的信号到达所述第一小区中的各区域时的信号质量等数值越大、代表终端受到的干扰强度越大的表示方式时，所述干扰门限取值范围通常指的是不超出某一设定的第一干扰门限值的数值区间。在此情况下，当确定所述实际干扰大小的叠加值不大于所述设定的第一干扰门限值时，即可认为所述实际干扰大小的叠加值不超出所述设定的干扰门限取值范围；当确定所述实际干扰大小的叠加值大于所述设定的第一干扰门限值时，即可认为所述实际干扰大小的叠加值超出所述设定的干扰门限取值范围。
再例如，当各第二小区相对所述第一小区中的各区域的历史参考干扰大小或实际干扰大小的表示方式为各第二小区与所述第一小区中的各区域之间的距离、或各第二小区发射的信号到所述第一小区中的各区域时的信号损耗等数值越大、代表终端受到的干扰强度越小的表示方式时，所述干扰门限取值范围通常指的是不低于某一设定的第二干扰门限值的数值区间。在此情况下，当确定所述实际干扰大小的叠加值不小于所述设定的第二干扰门限值时，即可认为所述实际干扰大小的叠加值不超出所述设定的干扰门限取值范围；相应地，当确定所述实际干扰大小的叠加值小于所述设定的第二干扰门限值时，即可认为所述实际干扰大小的叠加值超出所述设定的干扰门限取值范围。
进一步地，需要说明的是，在本发明所述实施例中，所述设定的干扰门限取值范围可根据终端的业务类型进行调整设定，本发明实施例对此不作任何限定。
另外需要说明的是，在本发明所述实施例中，除了可采用基于预设的用于表征各第二小区相对所述第一小区中的各区域的历史参考干扰大小的干扰矩阵以及各第二小区的频谱资源实时占用状态，确定所述终端能否使用第二小区所配置的各频谱资源中的任一频谱资源之外，还可采用按照一定的测量周期，实时测量位于第一小区任一区域内的终端所待使用的任一频谱资源受到的来自各第二小区的实时干扰大小的叠加值的方式，来确定所述终端能否使用所述任一频谱资源，本发明实施例对此不作赘述。
例如，以LTE为例，可按照一定的测量周期，实时测量共享频谱(即GSM小区所配置的频谱资源)上每个RB或者RBG受到的干扰能量，若RB或者RBG上受到的干扰能量超出设定的干扰门限取值范围时，则可认为该RB或RBG不可调度，直到某个测量周期测量到该RB或RBG受到的干扰能量不超出设定的干扰门限取值范围时，则可认为该RB或者RBG可调度。
进一步地，本发明实施例一还提供了一种与图2所示的网络侧协调设备基于同一发明构思的另一种网络侧协调设备(即实体网络侧协调设备)。如图4所示，其为本发明实施例一中所述另一种网络侧协调设备的结构示意图，所 述网络侧协调设备可包括接收器41、处理器42以及发送器43，其中：

其中，各第二小区相对所述第一小区中的各区域的历史参考干扰大小或实际干扰大小的表示方式至少可包括：
各第二小区发射的信号到达所述第一小区中的各区域时的信号强度、各第二小区发射的信号到达所述第一小区中的各区域时的信号质量、各第二小区与所述第一小区中的各区域之间的距离、各第二小区发射的信号到所述第一小区中的各区域时的信号损耗中的任意一种或多种。
进一步地，以所述第一小区为LTE系统下的任一小区，所述第二小区为GSM系统下的任一小区为例，所述处理器42具体可用于：
确定各第二小区的频谱资源实时占用状态S，所述频谱资源实时占用状态S可如下式所示：

根据所述干扰矩阵，确定在所述任一区域，所述终端所受到的来自第n个第二小区所配置的各频谱资源的历史参考干扰大小In，所述In可如下式所示：
In＝CELL_n(Y0，Y1，...，Yi)；其中，CELL_n(Yi)表示在所述任一区域， 所述终端所受到的来自第n个第二小区所配置的第i个频谱资源的历史参考干扰大小；以及，
通过以下公式确定在所述任一区域，所述终端待使用的任一频谱资源所受到的来自各第二小区所配置的各频谱资源的实际干扰大小的叠加值I总：
I总＝CELL_1(X0*Y0*θ0+X1*Y1*θ1+...+Xi*Yi*θi)+CELL_2(X0*Y0*θ0+X1*Y1*θ1+...+Xi*Yi*θi)+...+CELL_n(X0*Y0*θ0+X1*Y1*θ1+...+Xi*Yi*θi)；其中，θ表示各频谱资源的干扰权重修正值；CELL_n(Xi*Yi)表示在所述任一区域，所述终端待使用的所述任一频谱资源所受到的来自第n个第二小区所配置的第i个频谱资源的实际干扰大小。

实施例四：
本发明实施例四提供了一种可适用于本发明实施例一中所述网络侧协调设备的干扰协调方法，如图9所示，其为本发明实施例四中所述干扰协调方法的流程示意图，所述干扰协调方法具体可包括以下步骤：
步骤101：网络侧协调设备接收位于第一小区的任一区域内的终端发起的干扰协调请求，所述干扰协调请求是所述终端在使用任一待使用频谱资源之前，向网络侧协调设备发起的。
需要说明的是，在本发明所述实施例中，第一小区内的终端待使用的任一频谱资源通常可指的是与第二小区配置的各频谱资源同频的频谱资源中的任一频谱资源，本发明实施例对此不作赘述。当然需要说明的是，第一小区内的终端待使用的任一频谱资源也可指的是与第二小区配置的各频谱资源不同频的频谱资源中的任一频谱资源，本发明实施例对此不作任何限定。其中，如前文所述，所述第一小区为第一系统下的任一小区，所述第二小区为第二系统下的任一小区，并且，所述第二小区为所述第一小区的相邻小区，本发 明实施例对此不作赘述。
另外需要说明的是，在本发明所述实施例中，若以所述第一小区为LTE小区为例，则由于在LTE系统中，是以RB(Resource Block，资源块)或RBG(Resource Block Group，资源块组)为最小资源单位对终端所使用的资源进行调度的，因此，此时，所述第一小区内的终端待使用的任一频谱资源通常可指的是任一RB或任一RBG；若以所述第一小区为GSM小区为例，则所述第一小区内的终端待使用的任一频谱资源通常可指的是任一频点，本发明实施例对此不作赘述。
步骤102：网络侧协调设备根据预先构建的用于表征各第二小区相对所述第一小区中的各区域的历史参考干扰大小的干扰矩阵，以及获取到的各第二小区的频谱资源实时占用状态，确定所述终端待使用的所述任一频谱资源所受到的来自各第二小区的实际干扰大小的叠加值。
具体地，由于无论是GSM系统还是LTE系统，小区下用户的话务分布特征是相对固定的，且具有一定的周期性，并且系统内小区站点的位置、发射功率等也都是相对固定的。因此，可利用GSM系统或LTE系统内各终端上报的测量信息获取小区的话务模型数据，进而根据获取的测量信息或话务模型数据构造能够表征GSM系统和LTE系统之间干扰关系的干扰矩阵。
具体地，在本发明所述实施例中，以用于表征各第二小区相对所述第一小区中的各区域的历史参考干扰大小的干扰矩阵为例，所述用于表征各第二小区相对所述第一小区中的各区域的历史参考干扰大小的干扰矩阵可是所述网络侧协调设备基于预先统计的设定时间段内的第一小区内的各终端上报的测量信息构建的。其中，所述测量信息具体可包括第一小区内的各终端接收到来自各第二小区的信号的信号强度、第一小区内的各终端接收到来自各第二小区的信号的信号质量、各第二小区与第一小区内的各终端所在位置之间的距离、各第二小区发射的信号到第一小区内的各终端所在位置的信号损耗中的任意一种或多种，本发明实施例对此不作任何限定。另外需要说明的是，所述用于表征各第二小区相对所述第一小区中的各区域的历史参考干扰大小 的干扰矩阵也可以是基于与第一小区共站同覆盖的第二小区内的各终端上报的测量信息所构建的，本发明实施例对此也不作任何限定。
进一步地，仍以用于表征各第二小区相对所述第一小区中的各区域的历史参考干扰大小的干扰矩阵为例，基于预先统计的设定时间段内的第一小区内的各终端上报的测量信息构建用于表征各第二小区相对所述第一小区中的各区域的历史参考干扰大小的干扰矩阵，可以包括以下步骤：
步骤S1：根据设定的区域划分规则，将所述第一小区的小区覆盖范围划分为N个子区域，所述N为任意自然数；具体地，可根据第一小区的小区覆盖范围内的各区域距离第一小区的服务基站的距离、第一小区的小区覆盖范围内的各区域接收到第一小区的服务基站的信号强度、第一小区的小区覆盖范围内的各区域接收到第一小区的服务基站的信号质量以及第一小区的服务基站到第一小区的小区覆盖范围内的各区域的路损等，将所述第一小区的小区覆盖范围划分为N个子区域，本发明实施例对此不作任何限定；需要说明的是，优选地，所述N通常可为大于1的自然数，本发明实施例对此不作赘述。
步骤S2：针对任一子区域，根据设定时间段内收集到的第一小区内的各终端上报的测量信息(具体可为设定时间段内收集到的位于所述任一子区域内的各终端上报的测量信息)，确定各第二小区所配置的各频谱资源相对所述任一子区域的历史参考干扰大小，并根据确定的各第二小区所配置的各频谱资源相对所述任一子区域的历史参考干扰大小，生成所述任一子区域对应的干扰子矩阵。
其中，各第二小区相对所述第一小区中的各区域的历史参考干扰大小的表示方式至少可以包括：各第二小区发射的信号到达所述第一小区中的各区域时的信号强度、各第二小区发射的信号到达所述第一小区中的各区域时的信号质量、各第二小区与所述第一小区中的各区域之间的距离、各第二小区发射的信号到所述第一小区中的各区域时的信号损耗中的任意一种或多种，本发明实施例对此不作任何限定。
步骤S3：将确定的各子区域对应的干扰子矩阵所形成的干扰子矩阵集合 作为构建的用于表征各第二小区相对所述第一小区中的各区域的历史参考干扰大小的干扰矩阵。
例如，如图3所示，可将CELL1(即第一小区)的小区覆盖范围划分为子区域1、子区域2、...、子区域N，并收集CELL1在子区域1和邻区CELL2、CELL3、...、CELLK(所述CELL2、CELL3、...、CELLK均为第二小区，且所述K的取值为大于等于1的任意自然数)之间的干扰关系数据，CELL1在子区域2和邻区CELL2、CELL3、...、CELLK之间的干扰关系数据，.....，CELL1在子区域N和邻区CELL2、CELL3、...、CELLK之间干扰关系数据，以形成不同位置小区间的干扰矩阵。其中，每个子区域对应的的干扰子矩阵可反应了在该子区域下邻区CELL2、CELL3、....、CELLK对CELL1的干扰影响，其中，所述干扰影响的表示方式可以是质量、距离、电平或者路损等。一个小区覆盖范围内所有划分的子区域对应的干扰子矩阵的集合就组成这个小区的干扰矩阵。依次类推，每个小区都可以按照上述干扰矩阵确定方式确定出用于表征周围各邻区相对所述小区中的各区域的历史参考干扰大小的干扰矩阵，本发明实施例对此不作赘述。
进一步地，需要说明的是，在本发明所述实施例中，在预先构建干扰矩阵之后，可实时或定时收集第一小区内的各终端上报的测量信息(或与第一小区共站同覆盖的第二小区内的各终端上报的测量信息)，并基于实时或定时收集到的第一小区内的各终端上报的测量信息(或与第一小区共站同覆盖的第二小区内的各终端上报的测量信息)对预先构建的干扰矩阵进行更新，本发明实施例对此不作赘述。例如，针对采用SON(Self-Organizing Network，自组织网络)架构的系统，该系统即可不断自动收集并刷新小区中的干扰矩阵数据，以达到对小区中的干扰矩阵数据进行实时或定时更新的目的。
另外需要说明的是，在本发明所述实施例中，除了可基于现网的测量信息构造干扰矩阵之外，还可使用仿真工具进行电平覆盖预测、以模拟现网的拓扑结构以及信号发射特点，并基于相应的仿真结果来构造干扰矩阵，本发明实施例对此不作赘述。
进一步地，仍以用于表征各第二小区相对所述第一小区中的各区域的历史参考干扰大小的干扰矩阵为例，在得到上述干扰矩阵之后，即可根据相应的干扰矩阵以及获取到的各第二小区的频谱资源实时占用状态，确定位于所述第一小区的任一区域内的终端待使用的任一频谱资源所受到的来自各第二小区的实际干扰大小的叠加值。
具体地，以所述第一小区为LTE系统下的任一小区，所述第二小区为GSM系统下的任一小区为例，根据构建的用于表征各第二小区相对所述第一小区中的各区域的历史参考干扰大小的干扰矩阵以及各第二小区的频谱资源实时占用状态，确定位于所述第一小区的任一区域内的终端待使用的任一频谱资源所受到的来自各第二小区的实际干扰大小的叠加值，可包括以下步骤：
步骤S1：确定各第二小区的频谱资源实时占用状态S，所述频谱资源实时占用状态S可如下式所示：
S＝{CELL_1(X0,X1,...,Xi),CELL_2(X0,X1,...,Xi),...CELL_n(X0,X1,...，Xi)}；其中，n为第二小区的数量且所述n为任意自然数；i表示各第二小区所配置的频谱资源的数量且所述i为任意自然数；Xi代表各第二小区所配置的第i个频谱资源的实时占用状态，其中，所述Xi的取值为1可表示频谱资源被占用、取值为0可表示频谱资源被释放。
具体地，所述网络侧协调设备可通过向各第二小区的控制设备下发频谱资源状态获取指令并接收各第二小区的控制设备返回的携带有相应频谱资源实时占用状态信息的响应消息的方式获取各第二小区的频谱资源实时占用状态，或者，可通过接收各第二小区的控制设备主动上报的各第二小区的频谱资源实时占用状态信息的方式，获取各第二小区的频谱资源实时占用状态，本发明实施例对此不作任何限定。其中，所述第二小区的控制设备可为所述第二小区的服务基站等设备，本发明实施例对此不作赘述。
步骤S2：根据构建的用于表征各第二小区相对所述第一小区中的各区域的历史参考干扰大小的干扰矩阵，确定在所述第一小区的所述任一区域，所述终端所受到的来自第n个第二小区所配置的各频谱资源的历史参考干扰大 小In，所述In可如下式所示：
In＝CELL_n(Y0，Y1，...，Yi)；其中，CELL_n(Yi)表示在所述任一区域，所述终端所受到的来自第n个第二小区所配置的第i个频谱资源的历史参考干扰大小；
步骤S3：通过以下公式确定在所述任一区域，所述终端待使用的任一频谱资源所受到的来自各第二小区所配置的各频谱资源的实际干扰大小的叠加值I总：
I总＝CELL_1(X0*Y0*θ0+X1*Y1*θ1+...+Xi*Yi*θi)+CELL_2(X0*Y0*θ0+X1*Y1*θ1+...+Xi*Yi*θi)+...+CELL_n(X0*Y0*θ0+X1*Y1*θ1+...+Xi*Yi*θi)。
其中，θ表示与第n个第二小区所配置的各频谱资源相对应的干扰权重修正值，CELL_n(Xi*Yi)可表示在所述任一区域，所述终端待使用的所述任一频谱资源所受到的来自第n个第二小区所配置的第i个频谱资源的实际干扰大小。具体地，与各第二小区所配置的各频谱资源相对应的干扰权重修正值通常可是根据历史收集数据样本中不同干扰小区、每个小区中不同干扰频点的干扰大小相对于实际干扰大小的预测误差所确定的，以用于根据实际情况对干扰大小进行相应修正，以使得最终计算得到的干扰大小趋近于事实上的实际干扰大小。
由上述内容可知，为了能准确评估第一小区中的某个位置处的终端受到的来自各第二小区的干扰状况，需考虑各第二小区实际所使用的资源。具体地，对于GSM小区来说，GSM小区配置的载频上有用户占用时和无用户占用时产生的干扰不同，载频上有一个用户和多个用户占用时产生的干扰也不同，且GSM小区配置的多个载频同时被占用时需要考虑总的干扰功率叠加。类似地，LTE的带宽内包含多个RB资源，LTE使用的RB资源不同对于GSM的干扰也是不同。因此，在计算GSM系统中的各GSM小区对LTE系统中的各LTE小区的干扰时，需要获知各GSM小区占用的载频以及每个载频上占用用户等情况；相应地，在计算LTE系统中的各LTE小区对GSM系统中的 各GSM小区的干扰时，则需要获知各LTE小区的RB占用情况。
步骤103：判断确定的所述实际干扰大小的叠加值是否不超出预设的干扰门限取值范围，若是，则向所述终端下发第一调度指示，指示所述终端能够使用所述任一待使用频谱资源；若否，则向所述终端下发第二调度指示，指示所述终端不能够使用所述任一待使用频谱资源。
具体地，在本发明所述实施例中，判断确定的所述实际干扰大小的叠加值是否不超出预设的干扰门限取值范围，通常是指：判断确定的所述实际干扰大小的叠加值是否位于所述预设的干扰门限取值范围所限定的数值区间内。
例如，当各第二小区相对所述第一小区中的各区域的历史参考干扰大小或实际干扰大小的表示方式为各第二小区发射的信号到达所述第一小区中的各区域时的信号强度、或各第二小区发射的信号到达所述第一小区中的各区域时的信号质量等数值越大、代表终端受到的干扰强度越大的表示方式时，所述干扰门限取值范围通常指的是不超出某一设定的第一干扰门限值的数值区间。在此情况下，当确定所述实际干扰大小的叠加值不大于所述设定的第一干扰门限值时，即可认为所述实际干扰大小的叠加值不超出所述设定的干扰门限取值范围；当确定所述实际干扰大小的叠加值大于所述设定的第一干扰门限值时，即可认为所述实际干扰大小的叠加值超出所述设定的干扰门限取值范围。
再例如，当各第二小区相对所述第一小区中的各区域的历史参考干扰大小或实际干扰大小的表示方式为各第二小区与所述第一小区中的各区域之间的距离、或各第二小区发射的信号到所述第一小区中的各区域时的信号损耗等数值越大、代表终端受到的干扰强度越小的表示方式时，所述干扰门限取值范围通常指的是不低于某一设定的第二干扰门限值的数值区间。在此情况下，当确定所述实际干扰大小的叠加值不小于所述设定的第二干扰门限值时，即可认为所述实际干扰大小的叠加值不超出所述设定的干扰门限取值范围；相应地，当确定所述实际干扰大小的叠加值小于所述设定的第二干扰门限值 时，即可认为所述实际干扰大小的叠加值超出所述设定的干扰门限取值范围。
进一步地，需要说明的是，在本发明所述实施例中，所述设定的干扰门限取值范围可根据终端的业务类型进行调整设定，本发明实施例对此不作任何限定。
另外需要说明的是，在本发明所述实施例中，除了可采用基于预设的用于表征各第二小区相对所述第一小区中的各区域的历史参考干扰大小的干扰矩阵以及各第二小区的频谱资源实时占用状态，确定所述终端能否使用第二小区所配置的各频谱资源中的任一频谱资源之外，还可采用按照一定的测量周期，实时测量位于第一小区任一区域内的终端所待使用的任一频谱资源受到的来自各第二小区的实时干扰大小的叠加值的方式，来确定所述终端能否使用所述任一频谱资源，本发明实施例对此不作赘述。
例如，以LTE为例，可按照一定的测量周期，实时测量共享频谱(即GSM小区所配置的频谱资源)上每个RB或者RBG受到的干扰能量，若RB或者RBG上受到的干扰能量超出设定的干扰门限取值范围时，则可认为该RB或RBG不可调度，直到某个测量周期测量到该RB或RBG受到的干扰能量不超出设定的干扰门限取值范围时，则可认为该RB或者RBG可调度。
也就是说，在本发明实施例四所述技术方案中，针对位于第一小区的任一区域内的终端，网络侧协调设备可根据预先构建的用于表征各第二小区相对所述第一小区中的各区域的历史参考干扰大小的干扰矩阵，以及各第二小区的频谱资源实时占用状态，确定所述终端待使用的任一频谱资源所受到的来自各第二小区的实际干扰大小的叠加值，并在判断确定的所述实际干扰大小的叠加值不超出预设的干扰门限取值范围时，确定所述终端能够使用所述任一频谱资源，以及，在判断确定的所述实际干扰大小的叠加值超出预设的干扰门限取值范围时，确定所述终端不能够使用所述任一频谱资源，其中，所述第一小区为第一系统下的任一小区，所述第二小区为第二系统下的任一小区，并且，所述第二小区为所述第一小区的相邻小区，从而可实现不同制式的系统在同一频率上同时部署，并根据频域上的干扰协调方法在不同制式 之间交替使用或者同时使用的效果，因而，可极大地提升频谱利用效率；并且，还可达到在不需要新购频谱的前提下，部署具备更大系统带宽的LTE、从而为终端用户提供更有竞争力的网络的目的。
实施例五：

其中，所述第一调度指示通常可以是网络侧协调设备在接收到所述干扰协调请求后，根据预先构建的用于表征各第二小区相对所述第一小区中的各区域的历史参考干扰大小的干扰矩阵，以及获取到的各第二小区的频谱资源实时占用状态，确定所述终端待使用的所述任一待使用频谱资源所受到的来自各第二小区的实际干扰大小的叠加值不超出预设的干扰门限取值范围时，向所述终端下发的；所述第二调度指示通常可以是网络侧协调设备确定所述终端待使用的所述任一待使用频谱资源所受到的来自各第二小区的实际干扰大小的叠加值超出预设的干扰门限取值范围时，向所述终端下发的；其中， 如前文所述，所述第一小区为第一系统下的任一小区，所述第二小区为第二系统下的任一小区，并且，所述第二小区为所述第一小区的相邻小区。
进一步地，在本发明所述实施例中，所述终端在向网络侧协调设备发起干扰协调请求之前、同时或之后，所述方法还可包括：
实时或定时向所述网络侧协调设备上报测量信息，以使得所述网络侧协调设备可根据所述终端上报的测量信息预先构建相应的干扰矩阵或对预先构建的干扰矩阵进行相应更新等操作，本发明实施例对此不作赘述。
其中，所述测量信息具体可包括所述终端接收到来自各第二小区的信号的信号强度、所述终端接收到来自各第二小区的信号的信号质量、各第二小区与所述终端所在位置之间的距离、各第二小区发射的信号到所述终端所在位置的信号损耗中的任意一种或多种。
也就是说，在本发明实施例五所述技术方案中，针对位于第一小区的任一区域内的终端，所述终端可在使用任一待使用频谱资源之前，向网络侧协调设备发起针对所述任一待使用频谱资源的干扰协调请求，并在接收到网络侧协调设备下发的第一调度指示时，根据所述第一调度指示使用所述任一待使用频谱资源，或者，在接收到网络侧协调设备下发的第二调度指示时，根据所述第二调度指示拒绝使用所述任一待使用频谱资源，其中，所述第一调度指示可以是网络侧协调设备在接收到所述干扰协调请求后，根据预先构建的用于表征各第二小区相对所述第一小区中的各区域的历史参考干扰大小的干扰矩阵，以及获取到的各第二小区的频谱资源实时占用状态，确定所述终端待使用的所述任一待使用频谱资源所受到的来自各第二小区的实际干扰大小的叠加值不超出预设的干扰门限取值范围时，向所述终端下发的；所述第二调度指示可以是网络侧协调设备确定所述终端待使用的所述任一待使用频谱资源所受到的来自各第二小区的实际干扰大小的叠加值超出预设的干扰门限取值范围时，向所述终端下发的；所述第一小区为第一系统下的任一小区，所述第二小区为第二系统下的任一小区，并且，所述第二小区为所述第一小区的相邻小区，从而可实现不同制式的系统在同一频率上同时部署，并根据 频域上的干扰协调方法在不同制式之间交替使用或者同时使用的效果，因而，可极大地提升频谱利用效率；并且，还可达到在不需要新购频谱的前提下，部署具备更大系统带宽的LTE、从而为终端用户提供更有竞争力的网络的目的。
实施例六：
