For example, if all the conditions are met, the spectrum resource that can be allocated for the newly added vertex is channel 2.
  • the method for determining resource redistribution based on random network characteristics includes, for example:
  • Random network characteristics Because the degree of influence generated by vertices in the network is close to symmetry, when the vertices in the network are removed or added, the impact on the overall allocation result is small, so only the local correction of the resource allocation result satisfies the resource allocation constraint of the whole network. The possibility is higher. Therefore, in a random network, when the nodes are removed or added, the local correction allocation method can be performed first, and only when the local correction method cannot satisfy the spectrum requirements of all nodes, then the full reallocation is considered.
  • Scale-free network characteristics Because the degree of influence of vertices in the network is severely asymmetrical, a small number of vertices have more chances to connect with other vertices. Once these vertices are removed or added, the network structure will be greatly affected. The local correction of resource allocation results will not enable the resources to be effectively utilized. The new structure should be re-allocated to ensure the effective use of resources. Therefore, in the scale-free network, it is necessary to distinguish whether the removed or added node is a Hub point, and the Hub point can be determined according to the weighting degree in the fitting result. If the node removed or added is a Hub Point, you need to select the full reassignment method. If it is not a Hub point, the local correction allocation method can be performed first, and then the full re-allocation is considered only when the local correction method cannot satisfy the spectrum requirements of all nodes.

Description

频谱管理装置和方法、无线网络管理装置和方法以及介质 技术领域
本公开一般涉及无线通信领域。更具体地，涉及用于频谱管理的电子装置、频谱管理方法、无线网络管理装置、无线网络管理方法以及计算机可读介质。
背景技术
随着无线设备数量及无线业务多样性的快速增长，频谱稀缺问题日益严重。一种有前景的解决方案是频谱共享，通过共存协调实现多个系统共享目标频段，提升资源使用效率。目前被开放用于共享的频段称作非授权频段(Unlicensed Frequency Band)，例如包括3.5GHz、5GHz、6GHz等。
图论对于系统化表示网络信息，不论是物理结构还是逻辑结构，有着天然的优势。图论研究中积累的丰富模型和算法为网络资源分配有效解决方案，因此当前备受工业界重视。越来越多的标准采用构造网络图模型并基于该模型进行资源分配的方法，例如包括无线创新论坛(Wireless Innovation Forum(WINNF))组织制定的频谱访问系统(Spectrum Access System,SAS)，其研究3.5GHz频段上多系统间的共存管理，以及欧洲委员会(European Commission)发起的项目宽带无线接入网络(Broadband Radio Access Networks(BRAN))，其研究无线接入系统/无线局域网(WAS/RLAN)在5GHz频段的中央协作。
发明内容
图具有丰富的拓扑结构，不同的拓扑结构具有不同的特性。细微的拓扑变化可能使得基于图论的资源分配结果产生极大的差异，导致资源分配结果不稳定，从而影响网络的扩展性。即，任何变化都需要重新构造图、重新计算频谱分配，再通知所有网络节点进行重配置。特别是当资源分配周期较长，如果仅依据瞬时网络拓扑结构进行资源分配，无法满足较长时间间隔内网络状态变化的需求。
针对以上问题中的至少一部分提出了本发明。
在下文中给出了关于本发明实施例的简要概述，以便提供关于本发明的某些方面的基本理解。应当理解，以下概述并不是关于本发明的穷举性概述。它并不是意图确定本发明的关键或重要部分，也不是意图限定本发明的范围。其目的仅仅是以简化的形式给出某些概念，以此作为稍后论述的更详细描述的前序。
根据一个实施例，一种用于频谱管理的电子装置包括处理电路，处理电路被配置为生成测量配置信息以及进行控制以将测量配置信息发送给一个或多个无线网络管理装置。测量配置信息包括测量方式，测量方式包括以下方式中的至少一种：电子装置管理的无线网络管理装置进行测量，以及无线网络管理装置的一个或多个特定的节点进行测量。
根据另一个实施例，一种频谱管理方法包括生成测量配置信息以及将测量配置信息发送给一个或多个无线网络管理装置。测量配置信息包括测量方式，测量方式包括以下方式中的至少一种：电子装置管理的无线网络管理装置进行测量，以及无线网络管理装置的一个或多个特定的节点进行测量。
根据又一个实施例，一种无线网络管理装置包括处理电路，处理电路被配置为进行控制以从频谱管理装置接收测量配置信息。测量配置信息包括测量方式，测量方式包括以下方式中的至少一种：由无线网络管理装置进行测量，以及无线网络管理装置的一个或多个特定的节点进行测量。处理电路还被配置为基于测量方式来控制测量。
根据再一个实施例，一种无线网络管理方法包括从频谱管理装置接收测量配置信息的步骤。测量配置信息包括测量方式，测量方式包括以下方式中的至少一种：由无线网络管理装置进行测量，以及无线网络管理装置的一个或多个特定的节点进行测量。无线网络管理方法还包括基于测量方式来控制测量的步骤。
本公开实施例还包括计算机可读介质，其包括可执行指令，当可执行指令被信息处理设备执行时，使得信息处理设备执行根据本公开实施例的方法。
通过本公开实施例，有利于提高资源分配结果的稳定性以及网络的可扩展性。

具体实施方式
下面将参照附图来说明本发明的实施例。在本发明的一个附图或一种实 施方式中描述的元素和特征可以与一个或更多个其它附图或实施方式中示出的元素和特征相结合。应当注意，为了清楚的目的，附图和说明中省略了与本发明无关的、本领域普通技术人员已知的部件和处理的表示和描述。
如图1所示，根据本实施例的用于频谱管理的电子装置100包括处理电路110。处理电路110例如可以实现为特定芯片、芯片组或者中央处理单元(CPU)等。
处理电路110包括生成单元111和发送单元113。需要指出，虽然附图中以功能块的形式示出了生成单元111和发送单元113，然而应理解，这些单元的功能也可以由处理电路110作为一个整体来实现，而并不一定是通过处理电路110中分立的实际部件来实现。另外，虽然图中以一个框示出处理电路110，然而电子装置100可以包括多个处理电路，并且可以将生成单元111和发送单元113的功能分布到多个处理电路中，从而由多个处理电路协同操作来执行这些功能。
生成单元111被配置为生成测量配置信息。测量配置信息可以包括测量方式，测量方式可以包括由电子装置管理的无线网络管理装置进行测量或者由无线网络管理装置的一个或多个特定的节点进行测量。
更具体地，特定的节点例如可以包括用户设备(UE)或专门用于进行测量的节点(下文中可称为专门节点)。
此外，根据一个实施例，测量配置信息还可以包括测量对象信息，测量对象信息例如可以包括与无线网络管理装置的工作模式有关的信息以及与无线网络管理装置受到邻近无线网络的干扰模式有关的信息。
更具体地，与工作模式有关的信息例如可以包括无线网络管理装置在预定时间段内的累计工作时长、无线网络管理装置在预定时间段内的连续工作时长或者连续空闲时长的分布等。与干扰模式有关的信息例如可以包括无线网络管理装置在预定时间段内受到的来自邻近无线网络的干扰的分布。
发送单元113被配置为进行控制以将生成单元111所生成的测量配置信息发送给一个或多个无线网络管理装置。
根据一个实施例的电子装置100可以应用于3.5GHz频段上的公民宽带无线服务(CBRS)，电子装置100可以被配置在频谱接入系统(SAS)或共存管理器(CxM)侧，并且无线网络管理装置包括民用宽带无线服务装置(CBSD)。
根据另一个实施例的电子装置100可以应用于5GHz宽带系统(Broadband System)，电子装置100可以被配置在C3实体侧，并且无线网络管理装置可以包括无线接入系统(WAS)或无线局域网(RLAN)。
虽然本公开中以3.5GHz和5GHz为例进行说明，然而本发明不限于此，而是对其它非授权频段同样适用。此外，本发明实施例中对非授权频谱的使用满足对应非授权频谱上的使用要求，例如对该频段上主用户(Incumbent user)的保护或者对较高优先级用户的保护。
图2示出了根据一个实施例的用于频谱管理的电子装置的配置示例。电子装置200包括处理电路210，处理电路包括生成单元211、发送单元213、接收单元215和确定单元217。生成单元211和发送单元213与前面参照图1说明的生成单元111和发送单元113类似。
接收单元215被配置为进行控制以接收来自一个或多个无线网络管理装置的测量结果以用于确定对无线网络管理装置的资源分配。这里，资源分配可以包括资源的初始配置或重分配。
确定单元217被配置为基于与多个无线网络管理装置有关的测量结果，确定多个无线网络管理装置受到的来自邻近无线网络的干扰的统计结果的分布。
根据一个实施例，确定单元217还被配置为基于统计结果的分布确定多个无线网络管理装置的拓扑结构的类型，并且基于所确定的拓扑结构的类型来确定资源分配。
接下来，结合具体示例说明根据本发明实施例的统计网络拓扑的测量的示例方式。该过程可以描述为：由频谱管理装置(SM)为无线网络管理装置(WNM)设定第一测量配置，并将第一测量配置发送给WNM；WNM接收到第一测量配置，解析该测量需求，以确定是否需要第二测量。
如果需要第二测量，则为UE和/或专门节点设定第二测量配置，并发送给UE和/或专门节点。如果不需要第二测量，则WNM可以根据第一测量配置进行相应测量及上报给SM。
此外，在需要第二测量的情况下，UE或者专门节点可以根据第二测量配置进行相应测量及上报第二测量结果给WNM，再由WNM对收到的结果进行处理以形成第一测量结果，再根据第一测量配置上报给SM。
接下来，对第一测量进行更详细的说明。
第一测量配置可以由SM产生，发送给WNM，由WNM对该配置进行解析、测量和结果上报。WNM通常是所在无线网络的接入节点(例如，蜂窝通信网的eNB、gNB、或者WiFi的接入点(AP))。第一测量相关信令流程如图6所示。
测量对象可以包括无线网络的工作模式以及来自邻居无线网络的干扰模式。
无线网络的工作模式可以包括无线网络的累计工作时长，例如给定时间窗口中该无线网络的累计工作时间。或者，无线网络的工作模式可以包括无线网络的连续工作时长(或者连续空闲时长)的分布，例如给定时间窗口中连续工作时长(或者连续空闲时长)的均值和方差。
来自邻居无线网络的干扰模式可以包括给定时间窗口中无线网络接收到的来自邻居无线网络的干扰的分布，例如信号接收强度的均值和方差。此外，干扰模式可以包括邻居无线网络的ID列表。更进一步，还可以包括该分布的测量方式，例如包括WNM测量结果(称为测量方式1)、无线网络范围内均匀分布的节点的测量结果(称为测量方式2)、无线网络与邻居无线网络覆盖边缘区域的节点的测量结果(称为测量方式3)。
此外，例如可以通过以下方式来进行测量的报告：
将测量结果周期性地提交给SM，其中每个无线网络的报告周期可以由SM决定，周期例如可以是以小时为单位或者天为单位；
只在接到来自SM的测量请求时进行测量报告；或者
只在触发事件发生或被无线网络检测到时进行测量报告，触发事件例如可以包括测量对象的结果在事件定义的范围内，或者测量对象的结果量化等级发生变化等。
接下来，说明测量的示例方式。根据测量配置，可以在规定的时间窗口内进行工作时间累加以得出无线网络的累计工作时长。根据测量配置，可以在规定的时间窗口内统计连续工作时长(或者连续空闲时长)的参数，然后计算时长分布，例如包括均值和方差，以确定无线网络的连续工作时长(或者连续空闲时长)的分布。根据测量配置，可以在规定的时间窗口内测量邻居无线网络的信号强度(RSRP)，完成后计算该信号强度的分布，例如包括均值和方差，以确定来自邻居无线网络的干扰模式。
接下来，说明测量报告的触发方式的示例。根据报告配置，以相应的方 式触发测量报告。WNM根据第一测量配置将所需信息报告给SM。
所报告的测量结果可以是测量样本，也可以根据测量样本拟合的分布(例如包含均值和方差)。采用哪种形式的测量结果进行上报需要根据测量配置指示。SM在测量配置设定该指示时例如可以考虑信息交互开销和信息使用目的等因素。例如，与报告样本相比，报告分布信息所需的开销较小。此外，在测量结果用于分析网络拓扑特性进而决定资源分配的类型的情况下，对于网络拓扑特性的描述，分布的信息已经足够进行判断，因此样本信息上报并非必要。
在WNM收到第一测量配置后，对其进行解析，以判断是否需要第二测量。实施测量的节点可以包括以下情形之一：
情形1：由WNM进行测量；
情形2：由UE进行测量，如果是该情形，WNM需要为UE设定第二测量配置，并发送给UE，流程如图7所示；
情形3：由专门节点进行测量，如果是该情形，WNM需要为专门节点设定第二测量配置，并发送给专门节点。
WNM根据第一测量配置中的测量对象、测量方式、以及网络节点(WNM、UE和/或专门节点)的测量能力决定是否需要第二测量。
当测量对象为无线网络的工作模式时，对应的信息可以由WNM获得，而不需要第二测量；
当测量对象为来自邻居无线网络的干扰模式，如果测量配置包含测量方式，则需要按照测量方式进行。例如，对于前述测量方式1(由WNM测量结果)，则由WNM进行测量，不需要第二测量；对于前述测量方式2(无线网络范围内均匀分布的节点的测量结果)和测量方式3(无线网络与邻居无线网络覆盖边缘区域的节点的测量结果)，则需要第二测量。并且如果UE有测量能力，则选择UE测量；如果UE没有测量能力(包括业务繁忙)并且配备了专门测量节点，则可以选用专门节点测量。
对于上述情形1，WNM根据第一测量配置进行相应测量及上报给SM。
对于上述情形2和情形3，UE或者专门节点根据第二测量配置进行相应测量及上报给WNM，WNM对收到的第二测量结果进行处理形成第一测量结果，再根据第一测量配置上报给SM。
接下来，结合实施例说明统计网络拓扑图(G)的拟合和分类，及资源分配。 该过程如图8所示，频谱分配装置SM根据接收到的第一测量结果，生成统计网络拓扑图、对该拓扑图基于拟合进行分类。频谱分配装置基于分类，对无线网络变化引起的资源重分配决策分配方法。
继续参照图2，根据一个实施例，确定单元217还被配置为基于测量结果生成多个无线网络管理装置的拓扑图。在该拓扑图中，无线网络管理装置对应于拓扑图的顶点，无线网络管理装置间的干扰对应于拓扑图的边。
可以为将满足以下条件的无线网络管理装置确定为所述拓扑图的顶点：累计工作时长超过预设阈值；以及/或者累计工作时长与平均连续工作时长之比超过预设阈值。
此外，可以基于以下条件确定为拓扑图的边：边所连接的两个无线网络管理装置满足作为拓扑图的顶点的条件；并且在两个无线网络管理装置中的至少一个测得来自另一个的信号强度的均值超过预设阈值。
根据一个实施例，确定单元217还可以被配置为通过以下方式确定边的权值：对于无向图，基于以下方式中的至少一种确定所述权值：两个方向的干扰强度均值中较大值、较小值、均值、加权和；对于有向图，分别针对每个方向基于该方向上的干扰强度均值确定相应权值。具体的边权可以是干扰强度测量结果，也可以是对应的量化等级。
进一步地，确定单元217可以基于拓扑图的顶点的加权度确定拓扑结构的类型。加权度为顶点所连接的边的权值之和。
接下来，以前述示例中描述的情形1和情形2为例说明统计网络拓扑图的拟合和分类的示例方式。情形3与情形2的区别是测量节点是专门节点，而非普通UE。
下面说明生成统计网络拓扑图的示例方式。
根据测量结果中的无线网络的工作模式，确定统计网络拓扑图中顶点。成为顶点的无线网络的要求例如包括：工作时长超过一定预设阈值，其表示工作时足够长，和周围其它无线网络相互影响时间长；工作时长与分布均值的比值超过一定预设阈值，其表示业务出现的频繁，和周围其它无线网络相互影响持续也较长；根据测量结果中的来自邻居无线网络的干扰模式，确定统计网络拓扑图中的边以及边上的权。
成为拓扑图中的边的要求例如包括：两个无线网络都属于网络拓扑图中的顶点；两个无线网络中，至少一个测得来自另一个无线网络的信号强度的 均值超过一定预设阈值；设定边权，如果是无向图，可以选择例如两个方向的干扰强度均值最大值、最小值、均值、加权和，如果是有向图，可以分别在不同方向表示该方向的干扰强度均值。此外，具体的边权可以是干扰强度测量结果，也可以是对应的量化等级。
下面说明统计网络拓扑图的拟合和分类的示例方式。
对统计网络拓扑图的关键参数的分布进行拟合，这些关键参数例如包括：顶点的度(degree)，顶点间路径长度(path length)，图的联通性的簇化系数(clustering coefficient)等。
以下以顶点的加权度为例进行说明。图顶点的度为顶点连接的边的个数，在一些实施例中顶点的加权度为顶点连接的边的权值之和。本发明实施例定义的拓扑图中，加权度的物理意义是顶点对应的无线网络受到的聚合干扰。其中聚合干扰是指，假设拓扑网络中与所述无线网络以边相连的无线网络与所述无线网络使用相同频谱资源同时进行发射，所述无线网络受到的来自其它无线网络的干扰的统计结果，该统计结果例如可以是干扰强度之和。
图的拓扑有多种类型，例如包括随机网络(Random Network)和无标度网络(Scale-Free Network)。
随机网络中顶点度的分布符合泊松(Poisson)分布特性，度主要分布在均值周围，而较大或者较小的度的概率呈指数衰减，如图9中的(a)所示。在图9中，圆形顶点对应无线网络，顶点间的边说明顶点对应的无线网络之间存在干扰，每个边的权假设为1，则顶点的加权度退化为度。
无标度网络中顶点度的分布符合幂指数分布，度为j的顶点概率为P(j)＝j^(-a)，其中j>0,a>0,a称为无标度指数(scale-free exponent)，如图9中的(b)所示。从图中可以看出，顶点1和2与其它顶点相比，度的值高的多，这类节点称为中心(Hub)点。
作为示例，可以利用顶点加权度进行以上两种分布的拟合，以最佳的结果确定对应拓扑的分类。
接下来，说明基于网络拓扑分类进行资源分配的示例实施方式。
根据一个实施例，确定单元217还可以被配置为基于所确定的拓扑结构的类型以及顶点的类型，确定与该顶点相对应的无线网络管理装置的变化所引起的资源重分配的方式。
如前所述，拓扑结构的类型可以包括随机网络和无标度网络。相应地， 资源重分配的方式可以包括：对于随机网络，可以尝试局部修正进行资源分配；对于无标度网络，需要进一步考虑顶点在拓扑网络中产生的影响程度，影响程度较大的顶点引起的拓扑变化需要针对整体结构重新进行资源分配；影响程度较小的顶点引起的拓扑变化可以尝试局部修正进行资源分配。
接下来，结合具体示例说明基于网络拓扑分类的资源分配。
参见图10中的(a)所示的网络拓扑图，顶点灰度对应不同的频谱。方框表示可分配的频谱，例如图示将该频谱划分为有3个可分配的信道，分别标识为1、2、3。图10中的(b)示意在10中的(a)的网络拓扑图中新增了一个无线网络，对应新增的虚线顶点a，该顶点a对应的无线网络与其它无线网络间的干扰如虚线边所示。现在顶点a向SM发起频谱资源请求，资源重分配的方法例如包括：
完全重新分配，即SM将图10中的(a)的拓扑图中的所有顶点的资源分配结果全部取消，根据图10中的(b)的拓扑图中的结构为图中所有顶点重新分配频谱资源，并满足图10中的(b)中顶点间的频谱分配约束条件；拓扑图的频谱分配约束条件为：以边相连的两个顶点不能分配到相同频谱资源。
局部修正分配，即SM保留图10中的(a)拓扑图中的顶点的资源分配结果，并以该分配结果作为约束条件，为新增的顶点a分配频谱。例如，满足所有条件，为新增顶点可分配的频谱资源为信道2。
基于随机网络特性决策资源重分配方法例如包括：
随机网络特性：因为顶点在网络中产生的影响程度接近对称，所以当该网络中的顶点去除或者添加对整体分配结果影响较小，所以仅通过资源分配结果的局部修正满足全网资源分配约束的可能性较高。所以，在随机网络中，当去除或者添加的节点时，可以先进行局部修正分配方法，只有当局部修正方法无法满足所有节点频谱需求时，再考虑完全重新分配。
无标度网络特性：因为顶点在网络中产生的影响程度严重不对称，少量的顶点拥有更多和其它顶点连接的机会。一旦这些顶点去除或者添加，会对网络结构产生较大影响，资源分配结果的局部修正无法使资源得到有效利用，应该对新结构重新进行资源分配，以保证资源的有效利用。所以，在无标度网络中需要区分去除或者添加的节点是否是Hub点，Hub点可以根据拟合结果中的加权度确定。如果去除或者添加的节点是Hub点，则需要选择完全重新分配方法。如果不是Hub点，可以先进行局部修正分配方法，只有当局部修正方法无法满足所有节点频谱需求时，再考虑完全重新分配。
如前所述，本发明实施例可以应用于3.5GHz频段上的公民宽带无线服务或5GHz宽带系统。接下来，对这两中应用实例进行进一步说明。
实例一：3.5GHz的CBRS
WINNF组织制定的频谱访问系统(SAS)研究3.5GHz频段上多系统间的共存管理。在美国3.5GHz频带一直用于国防部(Department of Defense,DoD)雷达系统，目前联邦通信委员会(Federal Communications Commission,FCC)在讨论将该频段通过频谱共享的方式用于商用。该共享系统是SAS的一部分，包含三个等级：
Incumbent用户代表最高等级，incumbent用户包含上述DoD雷达系统，固定卫星服务(Fixed Satellite Service,FSS)，以及有限时间内的特权陆地无线业务(grandfathered terrestrial wireless operations)；
其它统称公民宽带无线服务设备(Citizens Broadband Radio Service Device,CBSD)，公民宽带无线服务进一步包含优先访问许可证(priority access license,PAL)以及普通授权访问(General Authorized Access,GAA)两个等级。
频谱使用上，需要保护Incumbent用户不受到来自CBSD的有害干扰，并且需要保护PAL不受到来自GAA的有害干扰。CBRS以人口普查区(census tract)为单位进行资源分配，PAL可以使用3550-3650MHz范围内的频谱，以10MHz为单位以3年为期限发放，每个人口普查区的所有PAL所占总频谱不超过70MHz，其中每个PAL的频谱不超过40MHz。GAA在保证不对高级别用户产生有害干扰的前提下，可以使用3550-3700MHz范围内的频谱。用于资源管理的逻辑实体主要包括SAS以及域代理(Domain Proxy)，参见图11，其中域代理代表个体CBSD或者网络CBSD与SAS进行交互为CDSD获得服务。当然，CBSD也可以不通过域代理直接与SAS进行交互获得服务。
CBRS联盟(CBRS-A)组织制定技术规范(TS)，提供不同CBSD之间的共存。CBRS-A管理的共存组(Coexistence Group,CxG)中逻辑实体共存管理器(Coexistence Manager,CxM)负责遵循SAS的规则，管理GAA用户之间的共存，参见图12。
在本发明实施例应用于3.5GHz的CBRS的情况下，频谱分配装置SM可以为SAS或者CxM，无线网络管理装置WNM可以为CBSD，用户设备UE可以为终端用户设备(EUD)。
结构配置例如为，SAS管理CBSD，为CBSD生成第一测量配置。如果 测量需要，CBSD为EUD生成第二测量配置。SAS管理CxG，为GxG中的单位集合生成第一测量配置，GxG中的单位集合可能是一个或者多个CBSD。如果测量需要，GxG中的单位集合再为EUD生成第二测量配置。CxM管理CBSD，为CBSD生成第一测量配置，CBSD为EUD生成第二测量配置。CxM管理CxG，为GxG中的单位集合生成第一测量配置，GxG中的单位集合可能是一个或者多个CBSD。如果测量需要，GxG中的单位集合再为EUD生成第二测量配置。
实例二：5GHz宽带系统
开发用于5G宽带系统的技术是欧洲委员会(European Commission)的目标之一。研究成果包括宽带无线接入网络(BRAN)的项目：WAS/RLAN在5GHz频段的中央协作。
该系统中用于管理的逻辑实体叫做C3(中央控制和协调器(Central Controller and Coordinator))，其具体化的物理实体叫做C3实体(C3 Instance)。C3实体的实现可以是分布式互联互通的多个C3实体，通过信息交互实现对管理对象的中央协调。
该系统中的管理对象叫做WAS/RLAN。
