Description

一种网络频谱共享方法 技术领域
本发明涉及一种网络频谱共享方法，尤其涉及一种在具有相同优先级的不同网络之间的频谱共享方法，属于无线通信技术领域。
背景技术
近年来，异构组网(Heterogeneous Network，HetNet)受到了广泛关注。其灵活的组网方式可以满足多种不同的需求。参见图1，宏小区(Macro cell)的部署可以提供广域覆盖，而大量的诸如微小区(Micro cell)、微微小区(Pico cell)、家庭基站小区(Femto cell)等小小区部署不仅可以增强室内覆盖，还可以提供高速接入。与宏基站相比，小小区的基站发射功率要低的多。对于一些室内部署的小小区基站来说，其无线信号在穿过建筑物后会有较大的穿墙损耗。那么在一定的地理位置隔离条件下，异构组网的运营商之间是可以频谱共享且不会造成很强的干扰的。
同优先级频谱共享(Co-primary Spectrum Sharing)是一种新的频谱接入模式，不同运营商间可以实现同优先级的动态灵活的频谱共享。它需要两个或多个无线频段执照持有者通过协商，就如何共同使用各自的部分授权频段达成一致。整个频谱共享模式受国家频段管理机构支配。因此人们在假设一种新的模式：频段管理机构不再将一段频谱资源以独占的方式分配给某个运营商，而是同时分配给多个潜在的运营商(用户)。这些潜在的运营商(用户)需要根据某些特定的规则公平地共同使用这部分频谱资源。针对这种新的频谱使用模式，世界上已有组织和机构开始讨论。例如德国联邦网络管理机构在2004年5月关于固定宽带无线接入系统(Fixed BWA)中3.5GHz频段的分配讨论中就曾涉及。此外，美国联邦通信委员会在关于3650～3700MHz的light licensing方案中也提出了类似的概念。
图1为现阶段不同运营商部署的混合网络覆盖重叠场景。运营商A和运营商B在一个区域内都部署了网络。A1～A5为运营商A部署的5个小小区基站，B1～B4表示运营商B部署的4个小小区基站。图中两个运营商的网络之间覆盖重叠大致有三种情况：覆盖重叠度高；覆盖重叠度中等；覆盖重叠度低或者无覆盖重叠。不同运营商各自部署网络的策略可能有较大差异，且相互之间很难交互关于网络部署的细节信息，只能根据一些有限的非敏感信息对网络拓扑进行估测然后确定频谱分配方 法。因此若能了解不同运营商部署的网络覆盖拓扑，对运营商间协商频谱分配策略具有重要意义，可以提高频谱利用率。
发明内容
针对现有技术的不足，本发明所要解决的技术问题在于提供一种网络频谱共享方法。
为实现上述发明目的，本发明采用下述的技术方案：
一种网络频谱共享方法，用于第一网络(A)和第二网络(B)之间实现共享频谱分配，包括如下步骤：
测量第二网络(B)的网络信号；

与现有技术相比较，本发明具有如下的技术特点：
1.适用于一定范围内不同的运营商/网络/用户之间共享频谱资源。通过根据异运营商间的网络覆盖重叠程度，为不同的运营商合理分配共享频谱资源，实现了同优先级频谱共享，提高了整个通信网络的频谱利用率。
2.可以在同优先级的前提下实现公平的频谱共享，保证处于网络覆盖重叠区域的不同终端，能够公平地使用频谱资源，维护不同运营商的利益。

具体实施方式
下面结合附图和具体实施例对本发明做进一步的详细说明。
本发明所提供的网络频谱共享方法，可以应用于2G/3G/4G或未来其他无线通信网络中的任何一种，只是2G/3G等已有网络中目前还没有多运营商频谱同优先级共享的应用，但不排除本方法可以应用于2G/3G/的可能性。下文仅以4G-LTE网络为例说明不同运营商或者不同网络之间的频谱共享方案。以下主要讨论不同运营商的具有相同优先级的网络情况，同一运营商的具有相同优先级的不同网络的情况与之类似，在此不予赘述。
本网络频谱共享方法主要适用于具有相同优先级的网络。根据异运营商的网络间覆盖重叠程度，为运营商/网络之间进行频谱共享提供了一种合理的频谱划分方案，适用于一定范围内不同的运营商/网络之间在同优先级条件下公平地共享频谱资源。在某个网络间覆盖重叠区域内，运营商通过指导其部署的该区域内的用户终端(User Equipment，UE)进行异运营商测量，然后根据异运营商测量的结果，估计其他运营商在该区域内部署的网络与自己网络覆盖重叠的程度，并根据网络重叠覆盖拓扑信息得出了异运营商间共享频谱的分配方案。参见图2和图3，下面以运营商A和运营商B频谱共享的过程为例对本发明进行详细介绍。
运营商根据地理位置和覆盖范围将小小区划分为不同的组。运营商在进行分组时，需为每组分配相应的分组标识。分组完成后，小小区需将所属分组的分组标识告知小小区基站。本方法可以适用于小小区或宏小区，可以根据业务需要选择使用。
步骤1，不同网络分别进行异运营商测量和汇报。
运营商/网络的小小区基站需要指导各自的用户终端对不同的运营商进行网络信号测量。待用户终端对不同运营商的信息测量完成，需要根据事先定义好的格式向其所服务的基站将发送异运营商测量报告。基站接收到来自用户终端的异运营商测量报告后，将其连同分组标识转发至对应的运营商的运营管理节点(Operations and Maintenance,O&M)。运营管理节点根据异运营商测量报告以及分组标识判断，评估出在该分组标识代表的分组范围内的异运营商小小区的重叠程度指示(Overlap Degree Indicator)，从而可以确定异运营商的网络覆盖拓扑。
在本发明的一个实施例中，包括第一运营网/第一网络(以下称为：本运营商)A和第二运营网/第二网络(以下称为：异运营商)B。可以理解，所谓“本运营商”与“异运营商”是相对的，可以互换。本运营商A的某个小小区基站为SeNBA，运营管理节点为O&MA，SeNBA所服务的用户终端为UEA。异运营商B的某个小小区基站为SeNBB，运营管理节点为O&MB，SeNBB所服务的用户终端为UEB。下面以SeNBA进行异运营商测量和汇报进行介绍。
SeNBA所有的用户终端UEA进行异运营商测量。用户终端UEA发起异运营商测量可以有多种方式：一种是周期性测量，测量周期由运营商之间协商后基站预先配置好；另一种可以是事件触发，触发的事件可以是基站或者UE受到强干扰。发起条件可以根据业务需求进行设置，在此不赘述。
同时，SeNBB所有的用户终端UEB也进行异运营商测量。为简明表示，在图3中没有表示异运营商B(包括用户终端UEB及SeNBB等)的工作内容，其工作方式和内容与本运营商A相同。
SeNBB为UEA测量到的异运营商小小区基站。用户终端UEA根据SeNBB周期发送的参考信号来测量运营商B的SeNBB相应小小区的信号强度信息—参考信号接收功率(Reference Signal Received Power,RSRP)。测量完成后，UEA向其所属的小小区基站SeNBA发送异运营商网络信号测量报告。异运营商测量报告需按照定义好的格式进行发送，报告中包括用户终端UEA在被测小小区接收到的SeNBB的参考信号接收功率RSRP、所属运营商/网络标识(operator ID)及分组标识(group ID)、小区全网唯一标识(E-UTRAN Cell global Identifier，ECGI)。此外，如果被测小区属于某些封闭用户群，还应包含所属封闭用户群标识(CSG ID)；如果被测小区不属于某些封闭用户群，则无需报告封闭用户群标识。
步骤2，根据异运营商网络测量报告，评估本运营商小小区与异运营商小小区的网络重叠程度指示。
在步骤1中，本运营商的小小区基站向其所属的运营管理节点汇报异运营商网络测量报告。根据不同的小小区基站的网络测量报告，运营管理节点可以确定异运营商B的某个小小区与本运营商A的网络覆盖重叠情况。在本实施例中，通过网络覆盖的重叠程度指示来表示异运营商部署的小小区与本运营商网络的覆盖重叠程度。重叠程度指示有多种获得方式。由于一个异运营商部署的小小区可能被多个本运营商部署小区检测到，在本发明的一个实施例中重叠程度指示通过带RSRP权重的邻居关系值之和得到。重叠程度指示的计算过程如下：
如果本运营商A的一个小小区能测量到异运营商部署的某一小小区，则将异运营商B的该小小区的基准邻居关系值设为1；测量不到的即为0。然后计算每个测量到的异运营商该小小区的参考信号接收功率的权重值。最后将所有测量到该异运营商小小区的带权重的邻居关系值相加即为该小小区的重叠程度指示。由于基准邻居关系值为1，因此只需将每个小小区基站SeNBA测量到的异运营商B的该小小区的参考信号接收功率的权重值相加，即可得到异运营商B的该小小区的重叠程度指示。
在本发明的一个实施例中，小小区基站SeNBA将用户终端UEA的异运营商测量 结果转发至其所对应的O&MA。O&MA根据异运营商网络信号测量结果计算每一个被测量到的异运营商B小小区与本运营商A网络的重叠程度指示。因此被测量到的运营商B的小小区与本运营商A网络的重叠程度指示V的公式如下：
Figure PCTCN2015071503-appb-000001
其中，x为被测量到的基站SeNBB的序号，i为与第x个SeNBB有邻居关系的SeNBA的序号，N为与第x个SeNBB有邻居关系的SeNBA的数量,Wi是根据第i个所述本运营商基站SeNBA的用户终端汇报的来自第x个所述异运营商基站SeNBB的参考信号接收功率值，计算出的权重值。网络重叠程度指示V表征对本运营商A的小小区有干扰的异运营商B的基站，对本运营商A的小小区的干扰程度。公式1中权重值是简单求和，也可以是对Wi再加权求和等其他方式。
权重值与用户终端测量到参考信号接收功率值直接相关。表1中给出了一种权重值W和参考信号接收功率RSRP的映射关系。首先设定若干门限值R1、R2、R3……，并根据RSRP与门限值的大小，赋予相应的权重值。赋值的原则为参考信号接收功率值RSRP越高，则权重值越大。而对于门限值的设定，运营商可以根据实际情况自行设定，这里不再进行说明。
RSRP的范围 W的值
RSRP≥R1 1
R2≤RSRP＜R1 0.8
R3≤RSRP＜R2 0.5
… …
表1权重值W和参考信号接收功率RSRP的映射关系
作为另一种权重值W和参考信号接收功率RSRP的映射关系，可以根据不同SeNBA的用户终端UEA测量到的来自异运营商基站SeNBB的各个RSRP中，取最大值为R，Wi＝RSRPi/R。采用这种映射关系时，在极端情况下，两个运营商的网络覆盖重叠程度很低，R的值会很小，但根据Wi＝RSRPi/R计算出来的权重值Wi还是会较大。为避免这种情况，可以设定R的门限值，如果本运营商A的基站SeNBA的用户终端UEA测量到的各个RSRP均小于该门限值(即，最大值R小于该门限值)，这种情况就判定为网络覆盖重叠程度低。
步骤3，根据重叠程度指示，对异运营商小小区计数。
本发明中重叠程度指示为异运营商B与本运营商A的小小区网络信号重叠程度的一个重要参数。本运营商A的运营管理节点根据异运营商B小小区的重叠程度指 示值的大小，及其网络ID和所属分组ID，将同一网络的属于同一个分组的小小区按照重叠程度分为若干类。根据分类情况，统计每一类中包含小小区的数量。根据不同重叠程度的小小区数量，基本可以确定异运营商B的该分组的小小区网络与本运营商A的网络覆盖拓扑。在进行小小区分类时，首先需要定义重叠程度指示的门限值。该门限值用于划分小小区的不同覆盖重叠水平。
下面以重叠程度指示的两个门限值为例进行说明。两个门限值分别定义为TH1和TH2，其中TH1>TH2。因此通过两个门限值，将小小区按覆盖重叠程度可分为高、中、低三类。其中每一类对应的小小区数量分别用H、M、L表示。若重叠程度指示V>＝TH1，则表示此异运营商B部署的小小区与本运营商A的网络覆盖重叠程度高。此时高重叠度小小区数量加1，即H＝H+1；H表示与本运营商A部署的网络的覆盖重叠程度高的B运营商部署的小小区的数量。若重叠程度指示TH2<V<TH1,则表示此异运营商B部署的小小区与本运营商A的网络的覆盖重叠程度中等。此时中等网络覆盖重叠度的小小区数量加1，即M＝M+1；M表示与本运营商A部署的网络覆盖重叠程度中等的异运营商B部署的小小区的数量。其余情况，认为此异运营商小小区与本运营商网络覆盖重叠程度低。低重叠度小小区数量加1，即L＝L+1；L表示与本运营商A部署网络覆盖重叠程度低的B运营商部署小小区的数量。
门限值的设定，可以是根据本运营商A检测到的异运营商B的小小区的参考信号接收功率RSRP确定。例如，第一种方案是：不同SeNBA的用户终端UEA测量到的来自异运营商基站SeNBB的各个RSRP中，取最大值为R，门限值TH1设定为R的一个较大的比例(例如2/3)；门限值TH1设定为R的一个较小比例(例如1/3)。第二种方案是：根据本运营商A的经验数据设定固定的门限值。第三种方案是：本运营商A与异运营商B之间事先协商确定门限值。前两种方案中，运营商之间在交互基于网络覆盖拓扑的信息的时候，交互门限值。第三种方案不需要交互门限值。
待同一分组内的异运营商小小区按照上述的分类和计数方法处理完成后，可以确定在该分组小小区的异运营商网络覆盖拓扑结构，得到异运营商网络覆盖拓扑信息。
步骤4，不同网络间交互基于网络覆盖拓扑的信息。
利用运营商网络间覆盖重叠指示(inter-operator coverage overlap indicator)这一参数，表示不同网络间的重叠覆盖程度，其包含具有不同网络覆盖重叠程度的小小区数量，即，在步骤3中根据重叠程度指示得到的运营商的小小区数量。本运营商A的网络将具有与本运营商A网络之间的不同网络覆盖重叠度的异运营商B的小小区数量，这一信息与异运营商的网络交互后，各个运营商可以根据 该交互信息确定其部署的小小区对其他运营商的重叠覆盖情况。
运营商间进行交互的方式有两种：一是通过运营管理节点；二是通过频谱控制中心(spectrum controller)。通过运营管理节点交互时，运营商A的运营管理节点只需将运营商网络间覆盖重叠指示，至少包含H和L(一个门限值的情况)，可以包含M(两个门限值的情况)发送至运营商B的运营管理节点即可，这里不再赘述。当系统中存在频谱分配方案决策的频谱控制中心时，需要共享频谱的运营商通过各自的运营管理节点将异运营商网络间覆盖重叠指示发送至其所属的频谱控制中心，然后由运营商的频谱控制中心进行异运营商网络间覆盖重叠指示交互。
步骤5，根据基于网络覆盖拓扑的信息，协商运营商间频谱共享分配方案。
运营商之间根据交互信息所包含的不同网络覆盖重叠程度的小区数量H，M和L，确定自己独占频谱和/或共用频谱的比例。然后根据独占频谱和/或共用频谱的比例，运营商之间协商得出共用频段的分配比例。
在本方案中，两个运营商共享的频段分为三个部分，分别是：共用频段、只被一个运营商占用的频段(运营商A独占频谱)、只被另一个运营商占用的频段(运营商B独占频谱)。频谱资源划分结构如图4所示。频段资源分配的原则如下：如果不同的运营商的网络间覆盖重叠程度越高(即，H越大)，则运营商共用的频段越少，需要将更多的频段资源分配给运营商独自占用，以减轻运营商间的干扰；反之，若不同运营商部署的网络间覆盖重叠程度越低，则可以分配越多的频段给运营商共用，各自独立占用的频段(也称为：独占频谱)越少。
首先介绍运营商确定自己所需独自占用频谱和共用频谱的比例。根据不同网络覆盖重叠程度的小小区数量，每个运营商评估自己独立占用和共用频谱分配的比例。在确定二者之间的比例时，运营商可以根据实际情况采用不同的准则。
在本发明的一个实施例中，对运营商B部署的小小区来说，除了那些被运营商A测量到的异运营商B的高、中、低程度的网络覆盖重叠小小区数量总数为HB+MB+LB，还可能会有些异运营商B小小区并未被运营商A测量到，将这些小小区的数量记为ZB。本实施例中给出了两种确定频谱分配比例的准则，参见图5。
每个运营商获得不同网络间覆盖重叠程度的小小区数量后，根据频谱分配比例的准则(准则1)进行分配，即独占频谱在该运营商使用的频谱中的分配比例为
Figure PCTCN2015071503-appb-000002
共用频谱分配比例为
Figure PCTCN2015071503-appb-000003
以异运营商B为例，独占频谱在本运营商使用的频谱中的分配比例为
Figure PCTCN2015071503-appb-000004
共用频谱分配比例为
Figure PCTCN2015071503-appb-000005
或者，每个运营商根据另一种频谱分配比例的准则(准则2)进行分配：独占频谱在该运营商使用的频谱中的分配比例为
Figure PCTCN2015071503-appb-000006
共用频谱在该运营商使用的频谱中的分配比例为
Figure PCTCN2015071503-appb-000007
以异运营商B为例，独占频谱在该运营商使用的频谱中的分配比例为
Figure PCTCN2015071503-appb-000008
共用频谱在该运营商使用的频谱中的分配比例为
Figure PCTCN2015071503-appb-000009
可以理解，如果只有一个门限值，将本运营商A测量到的异运营商B的小小区分成高、低两类。则独占频谱在异运营商B使用的频谱中分配的比例为
Figure PCTCN2015071503-appb-000010
或者
Figure PCTCN2015071503-appb-000011
类似的，共用频谱在异运营商B使用的频谱中分配比例为
Figure PCTCN2015071503-appb-000012
或者
Figure PCTCN2015071503-appb-000013
由于一个门限值的情况与多个门限值的情况类似，下文不作单独的说明。
运营商根据相应的准则确定自身的频谱分配比例后，接下来需要协商运营商之间合理的频谱分配方案。图6中为本实施例中频谱共享分配比例。首先两个运营商之间共享的频谱定义为1。运营商A确定其需要独立占用频谱与共用频谱之间的比例为RA，运营商B独立占用频谱与共用频谱之间的比例为RB，运营商之间交互这两个比例RA和RB(作为网络覆盖拓扑信息),则可以根据运营商各自的分配比例方案得出运营商间频谱共享分配方案。
若根据分配准则1，则
Figure PCTCN2015071503-appb-000014
若根据分配准则2，则
Figure PCTCN2015071503-appb-000015
上述准则1或2还可以简化为：
准则1：运营商A独占频谱与共用频谱之间的比例
Figure PCTCN2015071503-appb-000016
准则2：运营商A独占频谱与共用频谱之间的比例
Figure PCTCN2015071503-appb-000017
其中，HA是根据运营商之间交互信息所获知的运营商A在给定区域内部署的小小区中，属于所述网络重叠程度高的小小区的数量；TA是运营商A在给定区域内部署 的所有的小小区数量，或是运营商B的用户终端检测到的运营商A在给定区域内部署的所有小小区数量(即ZA为0的情况)；MA是根据运营商之间交互信息所获知的运营商A在给定区域内部署的小小区中属于所述网络重叠程度中等类别的小小区的数量。
相应地，运营商B也可根据准则1或准则2确定其独占频谱和共用频谱之间的比例RB。
运营商A和运营商B之间交互根据准则1或2得到的各自的独占频谱与共用频谱之间的比例RA和RB，由此计算得到两段独占频谱以及共享频谱三部分的分配比例为：运营商A独占频谱与全部频谱的比例为
Figure PCTCN2015071503-appb-000018
运营商A和B共用频谱与全部频谱的比例为
Figure PCTCN2015071503-appb-000019
运营商B独占频谱与全部频谱的比例为
Figure PCTCN2015071503-appb-000020
全部频谱是指本运营商与异运营商之间的共用频谱以及各自独占频谱的总和。
作为步骤5的另一种实现方式，运营商之间根据交互的网络覆盖拓扑信息，协商运营商间合理的频谱分配方案，也可以采用以下方案。下述方案不需要运营商确定自己所需独自占用频谱和共用频谱的比例，而是运营商A和运营商B直接交互各自部署的小小区总数和测量到对方的不同网络覆盖重叠程度的小小区数量(作为网络覆盖拓扑信息)，再分别根据各自不同网络覆盖重叠程度的小小区数量直接分配频谱。运营商A和运营商B的运营管理节点在分别获得异运营商部署的不同网络覆盖重叠程度的小小区数量后，运营商A和运营商B之间交互异运营商不同网络覆盖重叠程度的小小区数量和本运营商部署的小小区总数，作为网络覆盖拓扑信息。即，运营商A将其部署的小小区总数HA+MA+LA+ZA以及测量到的运营商B的不同覆盖重叠程度的各个小小区数HB、MB、LB告诉运营商B；运营商B将其部署的小小区总数HB+MB+LB+ZB以及测量到的运营商A的各个小区数HA、MA、LA告诉运营商A。运营商A和运营商B分别按下述准则3进行频谱分配。作为另一种替代准则，运营商A和运营商B也可以分别按下述准则4进行频谱分配。与准则1或准则2相比，适用准则3或者准则4计算和交互的效率更高。
准则3：
运营商A独占频谱与全部频谱的比例为：
Figure PCTCN2015071503-appb-000021
运营商A和B的共用频谱与全部频谱的比例为：
Figure PCTCN2015071503-appb-000022
运营商B独占频谱与全部频谱的比例为：

运营商B独占频谱与全部频谱的比例为：
Figure PCTCN2015071503-appb-000026
准则3和4，可以归纳为以下规律：
第一网络(A)独占频谱、第二网络(B)独占频谱以及第一网络(A)与第二网络(B)的共用频谱，这三者之比为：第二网络(B)测量到的第一网络(A)的网络重叠程度高的小小区的数量：第一网络(A)测量到的第二网络(B)的网络重叠程度高的小小区的数量：两个网络的全部小小区中其余小小区数量。这三者之比也可以为：第二网络(B)测量到的第一网络(A)的网络重叠程度高与中的小小区的数量之和：第一网络(A)测量到的第二网络(B)的网络重叠程度高与中的小小区的数量之和：两个网络的全部小小区中其余小小区数量。
如果假设本运营商用户终端检测到的异运营商所有小小区数量为TA＝HA+MA+LA+ZA，TB＝HB+MB+LB+ZB，则上述准则3或4可以简化为：
准则3-1：
运营商A独占频谱与全部频谱的比例为：

运营商A和B的共用频谱与全部频谱的比例为：

运营商B独占频谱与全部频谱的比例为：
Figure PCTCN2015071503-appb-000032
其中，HA是根据运营商之间交互信息所获知的运营商A在给定区域内部署的小小区中属于所述网络重叠程度高的小小区的数量；HB是根据运营商之间交互信息所获知的运营商B在给定区域内部署的小小区中属于所述网络重叠程度高的小小区的数量；TA是运营商A在给定区域内部署的所有的小小区数量，或是运营商B的用户终 端检测到的运营商A在给定区域内部署的所有小小区数量；TB是运营商B在给定区域内部署的所有的小小区数量，或是运营商A的用户终端检测到的运营商B在给定区域内部署的所有小小区数量；MA是根据运营商之间交互信息所获知的运营商A在给定区域内部署的小小区中属于所述网络重叠程度中等类别的小小区的数量；MB是根据运营商之间交互信息所获知的运营商B在给定区域内部署的小小区中属于所述网络重叠程度中等类别的小小区的数量。
适用简化后的准则3-1，运营商A和运营商B之间交互的网络覆盖拓扑信息是，检测到的异运营商的网络覆盖重叠程度高的小小区数量H和本运营商部署的小小区总数T。即，运营商A将其部署的小小区总数TA以及测量到的运营商B的网络覆盖重叠程度高的小小区数HB告诉运营商B；运营商B将其部署的小小区总数TB以及测量到的运营商A的网络覆盖重叠程度高的小小区数HA告诉运营商A。
类似的，适用简化后的准则4-1，运营商A和运营商B之间交互的网络覆盖拓扑信息是，检测到的异运营商的网络覆盖重叠程度高和中的小小区数量H、M以及本运营商部署的小小区总数T。即，运营商A将其部署的小小区总数TA以及测量到的运营商B的网络覆盖重叠程度高和中的小小区数HB、MB告诉运营商B；运营商B将其部署的小小区总数TB以及测量到的运营商A的网络覆盖重叠程度高和中的小小区数HA、MA告诉运营商A。
考虑到共用频段将被两个运营商的小区复用，则共用频段的比例不需要如准则3和准则4中那么高，下述准则5和准则6使共用部分频段的划分更合理高效。

运营商B独占频谱与全部频谱的比例为：
Figure PCTCN2015071503-appb-000035
其中S1＝max{MA+LA+ZA,MB+LB+ZB}或者，S1＝max{TA-HA,TB-HB}。S1表示运营商A和运营商B采用共用频段小小区数量的最大值，各个运营商采用共用频段的小小区数量，即该运营商部署的小小区中除去与异运营商网络覆盖重叠程度高的小小区之外的小小区数量。
准则6：
运营商A独占频谱与全部频谱的比例为：
Figure PCTCN2015071503-appb-000036
运营商A和B的共用频谱与全部频谱的比例为：
Figure PCTCN2015071503-appb-000037
运营商B独占频谱与全部频谱的比例为：
Figure PCTCN2015071503-appb-000038
其中S2＝max{LA+ZA,LB+ZB}或者S1＝max{TA-HA-MA,TB-HB-MB}。表示该准则下运营商A和运营商B采用共用频段小小区数量的最大值，是所述运营商A部署的小小区数量中的网络重叠程度低的小小区及未被运营商B检测到的小小区的数量之和，以及所述运营商B部署的小小区数量中网络重叠程度低的小小区及未被运营商A检测到的小小区的数量之和，这两者之中的较大者。也可以是，所述运营商A部署的小小区数量减去网络重叠程度高和中的小小区数量，以及所述运营商B部署的小小区数量减去网络重叠程度高和中的小小区数量，这两者之中的较大者。
第一网络(A)独占频谱、第二网络(B)独占频谱以及第一网络(A)与第二网络(B)的共用频谱，这三者之比为：第二网络(B)测量到的第一网络(A)的网络重叠程度高的小小区的数量：第一网络(A)测量到的第二网络(B)的网络重叠程度高的小小区的数量：第一网络(A)与第二网络(B)采用的共用频段小小区数量的最大值。这三者之比也可以为：第二网络(B)测量到的第一网络(A)的网络重叠程度高与中的小小区的数量之和：第一网络(A)测量到的第二网络(B)的网络重叠程度高与中的小小区的数量之和：第一网络(A)与第二网络(B)采用的共用频段小小区数量的最大值。
值得注意的是，每个运营商部署的小小区中，除了能被异运营商测量到的网络覆盖重叠程度高、中、低的那些小小区(对应数量H、M、L)还可能有一些未被异运营商检测到的小小区(对应数量为Z)。这些未被异运营商测量到的小小区可认为与异运营商网络几乎无覆盖重叠。在上述准则1-准则6中，均认为这些未被异运营商检测到的小小区使用共用频段。事实上，这些小小区不仅可以使用共用频谱，还能使用分配给异运营商专用的频谱，而不会对该异运营商的网络造成强干扰。另一方面，这类小小区的数量Z也不会很大。综合考虑上述因素，运营商之间在协商共享频谱划分策略时，可以不考虑这些未被异运营商检测到的小小区，运营商只需交互异运营商测量得到的网络覆盖拓扑信息(即包含覆盖重叠程度高、中、低的小小区数量)，无需知道其他运营商部署的所有小小区数量，对应的频率划分准则可描述如下：
准则7：在上述准则1-准则6中，无论真实的ZA和ZB是何值，计算各段频谱分配比例时，将ZA和ZB设为0。换言之，准则1-6中TA是运营商B的用户终端检测到的运营商A在给定区域内部署的所有小小区数量，TB是运营商A的用户终端检 测到的运营商B在给定区域内部署的所有小小区数量，就是ZA和ZB均为0的情况。
具体而言，运营商A和运营商B之间交互异运营商不同网络覆盖重叠程度的小小区数量，即运营商A将其测量到的运营商B的各类小区数HB、MB、LB告诉运营商B；运营商B将其测量运营商A的各类小区数HA、MA、LA告诉运营商A。下面以准则3、4为例，说明ZA和ZB设为0(包括不同时为0)的情况。运营商A和运营商B分别按下述准则7-1(对应准则3)或准则7-2(对应准则4)进行频谱分配。准则1、2、5、6均可以将ZA和ZB设为0(包括不同时为0的情况)，与准则3、4的情况类似，不详细说明。
准则7-1：
ZA和ZB均为0的情况下，运营商A根据自己检测得到的运营商B小小区数量HB、MB、LB，以及从异运营商B交互得到的HA、MA、LA，计算出运营商A独占频谱与全部频谱的比例为：
Figure PCTCN2015071503-appb-000039
作为一种替代方式，ZA为0且ZB不为0的情况下，运营商A根据自己检测得到的运营商B小小区数量HB、MB、LB、ZB，再结合从异运营商B交互得到的HA、MA、LA，得到运营商A独占频谱与全部频谱的比例为：
Figure PCTCN2015071503-appb-000040
ZB为0且ZA不为0的情况与ZA为0且ZB不为0的情况类似。
运营商A和B的共用频谱与全部频谱的比例为：
Figure PCTCN2015071503-appb-000041
运营商B独占频谱与全部频谱的比例为：
Figure PCTCN2015071503-appb-000042
类似的，准则7-1中，运营商B独占频谱与全部频谱的比例、共用频谱与全部频谱的比例，均可以有ZA为0且ZB不为0的情况或者ZB为0且ZA不为0的情况，这里不再赘述。
准则7-2：
运营商A独占频谱与全部频谱的比例为：
Figure PCTCN2015071503-appb-000043
运营商A和B的共用频谱与全部频谱的比例为：
Figure PCTCN2015071503-appb-000044
运营商B独占频谱与全部频谱的比例为：
Figure PCTCN2015071503-appb-000045
类似的，准则7-2中，本运营商A独占频谱与全部频谱的比例、异运营商B独占频谱与全部频谱的比例、共用频谱与全部频谱的比例，均可以有ZA为0且ZB不 为0的情况或者ZB为0且ZA不为0的情况，这里不再赘述。
如图5中位于上部的图所示，根据本运营商A独占频谱与全部频谱的比例、异运营商B独占频谱与全部频谱的比例、共用频谱与全部频谱的比例，本运营商A将其使用的频谱中，接近异运营商B使用频谱的那一段频谱分配给共用频谱，将其使用的频谱中与异运营商B使用频谱较远的那段频谱分配成独占频谱。可以理解，本运营商A也可以不是这样分配频谱，也可以根据业务需要将分离的频段分配个共用频谱或独占频谱，只要满足前述准则即可。
综上所述，本发明所提供的网络频谱共享方法可以使异运营商间进行同优先级频谱共享。首先，运营商根据地理位置和覆盖范围将小小区分组，并分配分组标识；运营商进行异运营商测量和汇报，其所属的运营管理节点根据异运营商测量报告评估异运营商的小小区与自己网络的重叠程度，得出异运营商小小区的重叠程度指示；将同一分组的异运营商小小区按照重叠覆盖程度进行分类，再统计不同重叠覆盖程度的小小区数量，形成异运营商网络覆盖重叠指示；然后，运营商之间交互异运营商网络覆盖重叠指示。运营商将根据不同网络重叠覆盖程度的小小区数量进行频率资源分配协商。通过本网络频谱共享方法，可以使不同的运营商之间公平合理地共享频谱资源，提高整个通信网络的频谱利用率，保证了用户终端的通信质量。
上面对本发明所提供的网络频谱共享方法进行了详细的说明。对本领域的一般技术人员而言，在不背离本发明实质精神的前提下对它所做的任何显而易见的改动，都将构成对本发明专利权的侵犯，将承担相应的法律责任。
