Description

频谱管理装置、方法、地理位置数据库和次系统

技术领域
本公开涉及无线通信中的频谱资源的管理，尤其涉及一种用于包括主系统和次系统的无线通信系统的频谱管理装置、频谱管理方法、地理位置数据库、次系统和无线通信方法。
背景技术
随着计算机和通信技术的迅猛发展，全球信息网络正在快速向以网络之间互连的协议(IP)为基础的下一代网络(Next Generation Network,NGN)演进。下一代网络的一个重要特征是多种无线技术并存形成异构无线接入网络，其中，异构无线接入网络对频谱资源的使用存在优先级的差异。频谱管理涉及主系统(Primary System)和次系统(Cognitive Radio System，CRS)两部分。例如工作在电视频段的网络包含主系统和次系统两部分。主系统拥有对电视频段的许可使用权，次系统对该频段不具有许可使用权，当且仅当对同频主系统的干扰在允许的范围内可以和主系统共同使用该电视频段。
因此，在新到达的次系统或者已有次系统的新业务请求分配资源时，要同时考虑主系统以及已有次系统的频谱资源使用状态。随着网络运营，各系统状态不断变化，频谱资源分配结果的资源利用率越来越低导致尚未达到容量极限却无法接入更多次系统。为了解决上述问题，一种简单的方法是对次系统全体重新进行资源分配和系统配置，但是这种大量次系统重配置的方式会带来非常高的开销。

在下文中将结合附图对本公开的示范性实施例进行描述。为了清楚和简明起见，在说明书中并未描述实际实施方式的所有特征。然而，应该了解，在开发任何这种实际实施例的过程中必须做出很多特定于实施方式的决定，以便实现开发人员的具体目标，例如，符合与系统及业务相关的那些限制条件，并且 这些限制条件可能会随着实施方式的不同而有所改变。此外，还应该了解，虽然开发工作有可能是非常复杂和费时的，但对得益于本公开内容的本领域技术人员来说，这种开发工作仅仅是例行的任务。
在此，还需要说明的一点是，为了避免因不必要的细节而模糊了本公开，在附图中仅仅示出了与根据本公开的方案密切相关的装置结构和/或处理步骤，而省略了与本公开关系不大的其他细节。
对于包括主系统和次系统的通信系统，为了能够使主系统和次系统在同一或相邻频谱上减少相互干扰的同时合理利用频谱资源，本公开提出一种在保证对主系统不产生干扰的情况下、对次系统的频谱使用进行优化的方法，以实现对有限频谱资源的充分利用。通常，主系统包括主基站和主用户，次系统包括次基站和次用户。根据本公开，主系统可以是拥有许可频谱使用权的系统，相应地，次系统可以是没有许可频谱使用权的系统；根据本公开的另一个实施例，主系统也可以与次系统同时具有频谱使用权、但频谱使用优先级高于次系统的系统，在此情况下，次系统当且仅当对主系统的不产生有害干扰时可以与主系统共同使用许可频谱。主系统、次系统的概念是本领域公知的，在此不再对其进行详细描述。
图1示出了包括主系统和次系统的通信系统的一个示例的示意图。
如图1所示的通信系统包括三个主系统A、B和C、三个次系统a、b、c、以及用于管理次系统的频谱资源的频谱管理装置D1。
图1所示的通信系统仅仅是示例，本领域技术本领域技术人员可以理解，通信系统中所包括的主系统和次系统也可以是其他数目，例如包括两个或四个以上主系统等等。
在此需要说明，对于包括主系统和次系统的通信系统，当网络状态发生变化(例如存在有新的资源需求的次系统而需要为该次系统分配频谱资源)而需要对频谱资源进行调整时，至少需要满足外部约束条件，即该次系统在使用频谱资源时对主系统(例如图1中的主系统A、B、C)造成的干扰在主系统的允许范围之内。
此外，在存在多个次系统的情况下，当为请求频谱资源的次系统分配频谱资源时，需要确保要确保所有次系统在使用频谱资源时的聚合干扰在主系统的 容许范围之内。因此，在本公开中，当提及请求频谱资源的次系统在使用频谱资源时对主系统的干扰在所述主系统的允许范围内时，其意在表达在请求频谱资源的次系统使用所分配的频谱资源且当前通信系统中其他次系统在使用为其分配的频谱资源(即其当前正在使用的频谱资源)时、包括该次系统在内的所有次系统对主系统造成的聚合干扰。本领域技术人员可以使用现有技术中的任意方法，计算次系统对主系统造成的聚合干扰，其具体计算方式在此不再赘述。
图2示出了根据本申请的一个实施例的用于无线通信系统的频谱管理装置1，该无线通信系统包括主系统和次系统，频谱管理装置1包括：处理电路10，该处理电路10被配置为：获取该频谱管理装置所管理的次系统的频谱使用信息和频谱调整能力信息，该频谱使用信息对应于已经分配给各个次系统使用的使用频谱相关信息，该频谱调整能力信息对应于次系统是否支持频谱调整操作的相关信息，以及基于所述频谱使用信息和所述频谱调整能力信息，确定对该频谱管理装置所管理的次系统的频谱调整，以使得各个次系统的频谱使用对主系统造成的干扰在主系统的允许范围内。根据本公开，频谱管理装置1例如可以独立于地理位置数据库(Geo-location Data Base,GLDB)而设置或者可以设置在地理位置数据库中。
根据本公开，频谱使用信息是关于已经分配给各个次系统使用的频谱的信息。分配给各个次系统使用的频谱可以由相应的次系统使用，也可以由于该次系统当前没有资源需求而未被使用或仅使用部分。频谱管理装置1的处理电路10可以从例如地理位置数据库(GLDB)、或者各个次系统中获取次系统的频谱使用信息。地理位置数据库的定义及其获取使用频谱信息的具体方法是现有技术，在此省略了对其的详细描述。此外，由于频谱管理装置1可以用于对次系统进行频谱资源的分配，因此会维护每个次系统已经分配的频谱资源，例如将关于每个次系统所分配使用的频谱资源的信息存储在其存储单元中，从而处理电路10也可以从频谱管理装置1的存储单元中获取次系统的频谱使用信息。
频谱调整能力信息表示次系统进行频谱转移的能力。异构无线接入网络支持数量巨大、类型多样的次系统，在QoS需求上也存在多样性。例如，次系统可以是单个移动设备，也可能是由移动设备构成的网络。因此，不同的次系 统重配置带来的消耗也有所不同，导致对于频谱调整引起的重配置的敏感性有所差异。频谱调整能力信息的提供确保次系统能够根据自己的特征或需求选择是否加入频谱调整操作。这些特征或需求包括业务的重要性、参与频谱调整是否能够带来一些利益(例如换取虚拟货币或流量)等等。频谱调整能力信息可以在运行过程中由次系统根据自己的特征或需求动态地设定。例如，频谱调整能力信息可以由spectrumTransitionCapability表示。频谱调整能力信息的值可以以例如布尔量表示，例如设为“TRUE”表示该次系统支持频谱调整操作；否则，表示拒绝加入频谱调整操作。与频谱使用信息类似，处理电路10可以从例如地理位置数据库或各个次系统中获取次系统的频谱调整能力信息，或者也可以从频谱管理装置的存储单元中获取频谱调整能力信息。
此外，图2中还示出了处理电路10的功能模块的示例，如图2所示，处理电路10包括获取单元101和调整确定单元102。应该理解，这些功能模块可以分别由一个处理电路实现，也可以由一个处理电路共同实现，或者实现为一个处理电路的一部分，或者每一个功能模块可以由多个处理电路实现。换言之，功能模块的实现方式是非限制性的。其中，处理电路10例如可以为具有数据处理能力的中央处理单元(CPU)、微处理器、集成电路模块等。下面将参照图3详细描述频谱管理装置1的结构和功能。
作为一个示例，处理电路10还可以被配置为在有次系统请求频谱资源并且所述无线通信系统中存在剩余频谱资源的情况下，响应于该请求获取该频谱管理装置所管理的次系统的频谱使用信息，并且基于该频谱管理装置所管理的次系统的频谱使用信息，确定是否触发对所述次系统进行频谱调整，以满足请求频谱资源的次系统的频谱资源使用。
根据本公开，剩余频谱资源也可以是未达用户使用上限的频谱资源，其可以包括无线通信系统中未被使用的频谱资源、新释放的频谱资源以及其他未达用户使用上限的频谱资源。例如，如果无线通信系统中有某一频谱资源，其在保证对主系统造成的干扰在其干扰阈值范围内的情况下可以允许最多10个次系统使用，但是当前仅有5个次系统在使用该频谱资源，这表明该频谱资源的使用未达到其可容纳用户的上限(也就是说，该频谱资源未被充分利用，存在调整空间)。在下文的描述中，将除无线通信系统中未被使用的频谱资源、新 释放的频谱资源之外的其他未达用户使用上限的频谱资源称为未达用户使用上限的其他频谱资源。
相应地，如图3所示，处理电路10还可以包括调整触发单元103，用于确定是否触发对所述次系统进行频谱调整，以满足请求频谱资源的次系统的频谱资源使用。
根据本公开，在有次系统请求频谱资源并且所述无线通信系统存在剩余频谱资源的情况下，调整触发单元103可以响应于该频谱资源请求，确定是否触发次系统的频谱资源调整的操作。
图4示出了调整触发单元的一种示例性结构。
如图4所示，调整触发单元103可以包括：判断模块1031，被配置成判断无线通信系统中是否有剩余频谱资源以及该剩余频谱资源是否能够被请求频谱资源的次系统使用；以及触发确定模块1032，用于在所述判断模块1031判断无线通信系统中有剩余频谱资源并且该剩余频谱资源不能够被请求频谱资源的次系统使用的情况下，确定触发对于各个次系统的频谱使用的调整。
根据本公开的一个实施例，判断模块1031可以首先判断无线通信系统中的剩余频谱资源是否能被请求频谱资源的次系统使用。例如，判断模块1031可以判断剩余频谱资源是否属于请求频谱资源的次系统的可用频谱，如果剩余频谱资源属于请求频谱资源的次系统的可用频谱，则判断模块1031可以判断剩余频谱资源可以被请求频谱资源的次系统使用，从而处理电路10可以确定将该剩余频谱资源分配给该次系统。判断模块1031的上述判断例如可以基于获取单元101从地理位置数据库获取的该请求频谱资源的次系统的可用频谱列表而进行。根据本公开的可用频谱列表中包括在次系统对主系统的干扰在主系统允许范围内的条件下的、次系统的可用频谱相关信息。或者，判断模块1031也可以判断请求频谱资源的次系统在使用该剩余频谱资源的情况下对主系统造成的干扰是否在主系统的干扰阈值范围内，如果在主系统的干扰阈值范围内，则判断模块1031可以判断剩余频谱资源可以被请求频谱资源的次系统使用，从而处理电路10可以确定将该剩余频谱资源分配给该请求频谱资源的次系统。
在判断模块1031判断请求频谱资源的次系统可以获取剩余频谱资源的情 况下，可以将剩余频谱资源分配给该请求频谱资源的次系统，从而无需进行次系统的频谱调整，因此，触发确定模块1032确定不触发对于各个次系统的频谱使用的调整并且确定可以将剩余频谱资源分配给该请求频谱资源的次系统。
反之，在判断模块1031判断请求频谱资源的次系统不能获取剩余频谱资源的情况下，进一步地判断无线通信系统是否存在剩余频谱资源。如果第二判断模块1032判断无线通信系统中不存在剩余频谱资源，则表明无线通信系统中的所有频谱资源都已被充分利用，即不能通过对当前次系统的频谱使用进行调整而为请求频谱资源的次系统分配频谱资源，在此情况下，触发确定模块1032确定不触发对于各个次系统的频谱使用的调整并且确定拒绝接入有频谱资源请求的次系统。如果无线通信系统中存在剩余频谱资源，触发确定模块1032可以确定触发对于各个次系统的频谱使用的频谱调整，从而通过频谱调整、在其确保对主系统的干扰在主系统的干扰阈值范围内的情况下，为请求频谱资源的次系统提供频谱资源。
在触发确定模块1032确定不触发对各个次系统的频谱使用的频谱调整的情况下，频谱管理装置1可以确定拒绝接入该次系统。
根据本公开的调整触发单元103的确定是否触发对次系统进行调整的处理的触发操作也可以称为共存发现。
响应于调整触发单元103确定触发对频谱管理装置所管理的次系统进行频谱调整，处理电路10中的获取单元101可以获取其所管理的各个次系统的频谱调整能力信息，并且基于获取的频谱调整能力信息，选择支持进行频谱调整的次系统，并且由处理电路10中的调整确定单元102确定对于这些支持频谱调整操作的次系统的频谱调整。
虽然根据以上描述，处理电路10的获取单元101响应于频谱资源请求获取各个次系统的频谱使用信息以及响应于确定触发对次系统的频谱调整获取频谱调整能力信息，但是本公开不限于此。例如，获取单元101也可以在每个预定的定时获取该频谱管理装置所管理的各个次系统的频谱使用信息和频谱调整能力信息。
下面详细描述调整确定单元102的一种示例性结构。如图5所示，调整确定单元102包括：次系统集合确定模块1021，针对剩余频谱资源，在频谱管 理装置所管理的次系统中，选择如下次系统构成与该剩余频谱资源对应的次系统集合：该次系统未使用所述剩余频谱资源、但是在将剩余频谱资源调整为由该次系统使用时对主系统的干扰在所述主系统的允许范围内；判定模块1022，判定所述次系统集合中是否存在所述请求频谱资源的次系统：在存在所述请求频谱资源的次系统的情况下，基于该判断确定对该频谱管理装置所管理的次系统的频谱调整，当不存在请求频谱资源的次系统时，将所述次系统集合中包括的每一个次系统当前使用的频谱资源作为所述剩余频谱资源；针对次系统集合中包括的每一个次系统当前使用的频谱资源，重复次系统确定模块1021和判定模块1022的上述操作，直到所述次系统集合中存在请求频谱资源的次系统为止。
根据本公开，次系统集合确定模块1021是基于如下条件而确定对于与剩余频谱资源对应的次系统集合中所包括的次系统：该次系统未使用所述剩余频谱资源、但是在将剩余频谱资源调整为由该次系统使用时对主系统的干扰在所述主系统的允许范围内；也就是说，如果将该剩余频谱资源调整为该次系统使用，在调整之后，整个通信系统中包括该次系统在内的所有次系统在使用频谱资源、即该次系统使用剩余频谱资源(根据本公开，如果该剩余频谱资源为某次系统释放的则对应次系统需要停止使用该剩余频谱资源)而其他次系统使用其当前在使用的频谱资源时对主系统造成的干扰在主系统的干扰阈值范围之内。
图6示出了当剩余频谱资源为新释放的频谱资源时、确定两个次系统之间的频谱调整(频谱转移)的示例。
如图6所示，通信系统中存在两个次系统CRSa和CRSb，其中CRSa使用频谱CH1，CRSb没有使用频谱CH1，PS1为任意一个使用CH1的主系统(或主系统参考点，其为用于计算对主系统干扰的等效位置点)。则仅当将频谱CH1从CRSa转移到CRSb后(即CRSb使用CRSa释放的频谱CH1)、CRSb给PS1带来的聚合干扰仍然在PS1可容忍的范围内时，认为可以将频谱CH1从CRSa转移到CRSb。如图6所示，IC→1表示当前系统中所有使用CH1的次系统给PS1带来的聚合干扰，其中C表示当前系统可用频谱列表包含CH1的次系统的集合；I1,th表示主系统PS1的干扰阈值。若将频谱CH1从CRSa转移到CRSb，PS1 受到的新聚合干扰计算为IC∪{b}\{a}→1，其中，C∪{b}\{a}集合运算表示从集合C中加入CRSb去掉CRSa构成新的次系统集合，若满足IC∪{b}\{a}→1≤I1,th则可以将频谱CH1从CRSa转移到CRSb，从而当CRSa释放其所使用的频谱资源CH1时，可以将CRSb包括在与所释放的剩余频谱资源CH1对应的次系统集合中。
仍以图6为例、以次系统CRSa释放其所使用的频谱资源CH1为例，说明确定与剩余频谱资源CH1对应的次系统集合的具体处理。但是本领域技术人员可以理解，在以下确定次系统集合的描述中，除非特别提及，频谱资源CH1也可以是无线通信系统中未被使用的频谱资源或者新释放的频谱资源。
在次系统CRSb当前未在使用频谱资源CH1的情况下，例如可以将在确定次系统CRSb使用剩余频谱资源CH1时对主系统造成的干扰是否在主系统的干扰阈值范围之内分为以下两种情形：
情形一：剩余频谱资源CH1虽然不属于次系统CRSb的使用频谱但是属于其可用频谱，这表明GLDB在为CRSb分配可用频谱时已经考虑了CRSb对PS1的干扰，所以CRSb属于集合C，所以C∪{b}\{a}＝C\{a}，即C∪{b}\{a}是C的真子集，则必定满足IC∪{b}\{a}→1≤I1,th。因此，对于该情况，可以直接通过频谱管理装置管理的各个次系统的可用频谱信息，确认可以将CRSb包括在与所释放的空闲频谱资源CH1对应的次系统集合中。
情形二：CH1不属于CRSb的可用频谱列表，则无法确认IC∪{b}\{a}→1和I1,th的关系，需要重新计算。
对于情形二，一种可能的实现方式为：频谱管理装置1可以访问地理位置数据库所有存储和计算的信息，即地理位置数据库针对频谱管理装置1所管理的每个次系统重新计算其在被调整为使用剩余频谱资源后对于主系统(或主系统参考点)的干扰是否在主系统的干扰阈值之内，如果在主系统的干扰阈值之内，则次系统集合确定模块1021将该次系统包括在与该剩余频谱资源对应的次系统集合之内，否则，则不将其包括在与该剩余频谱资源对应的次系统集合之内。然后，基于由次系统集合确定模块1021确定的次系统集合，由判定模块1022执行判定，以便基于该判定确定频谱调整方案。
为了进一步减小在确定次系统集合时的计算量，在剩余频谱资源为次系统新释放的频谱资源的情况下，次系统集合确定模块1021可以被配置为基于各 个次系统在保持当前频谱资源使用同时保证对主系统造成的干扰在主系统的允许范围内的条件下相对于主系统的可移动范围的信息，选择构成该次系统集合的次系统。根据本公开，可移动范围指的是在无线通信系统中，各个次系统保持使用其当前的使用频谱下在该可移动范围内移动不会对主系统造成有害干扰，即其对主系统造成的干扰在其允许范围之内。根据本公开，在无线通信系统中存在多个主系统的情况下，次系统相对于多个主系统中的每个主系统具有一个可移动范围。
通常，地理位置数据库在给任何一个次系统CRS或频谱管理装置发送的次系统的可用频谱信息中还包括该次系统的可移动范围的信息(即在保持当前频谱资源使用下、次系统在该可移动范围内运动将不会增加对于目标主系统(或主系统参考点)的聚合干扰)。根据本公开，可以使用该可移动范围信息选择构成与被释放的该剩余频谱资源对应的次系统集合的次系统，并基于所选择的次系统确认在将所选择的次系统调整为使用剩余频谱资源后对主系统造成的干扰是否在主系统的干扰阈值范围内，以缩小尝试范围，降低计算量。
根据本公开，当考虑次系统CRSa使用的频谱资源CH1(即，将其视为根据本公开的剩余频谱资源)的调整目标(即在频谱调整时，可以使用频谱资源CH1的次系统，也即本公开中所提及的与剩余频谱资源对应的次系统集合中的次系统)时，仅需要考虑处于释放频谱资源CH1的次系统CRSa可移动范围内并且没有使用该频谱资源的其它次系统作为潜在的调整目标。
根据本公开，次系统集合确定模块1021被配置为选择在该频谱管理装置所管理的、在释放该剩余频谱资源的次系统的所述可移动范围内的次系统构成与该剩余频谱资源对应的次系统集合。
在所述无线通信系统包括一个主系统的情况下，次系统集合确定模块1021可以选择在该频谱管理装置所管理的、在释放该剩余频谱资源的次系统的所述可移动范围内的次系统构成与该剩余频谱资源对应的次系统集合。
在所述无线通信系统包括多于一个主系统的情况下，次系统集合确定模块1021可以选择位于释放该剩余频谱资源的次系统的多个可移动范围的重叠区域内的次系统，构成与该剩余频谱资源对应的次系统集合。
优选地，距离主系统越远的次系统对于主系统的干扰越小。即，以下情况 有非常大的可能性：相比于释放剩余频谱资源的次系统，位于更远离主系统位置的次系统在使用剩余频谱资源对主系统造成的干扰更小。基于此，可以考虑选择上述可移动范围内相比释放该剩余频谱资源的次系统处于更远离所述主系统的位置的次系统构成与该剩余频谱资源对应的次系统集合。
下面结合图7(a)和图7(b)详细描述次系统集合确定模块1021基于次系统的可移动范围确定构成与剩余频谱资源对应的次系统集合中的次系统的具体处理。
图7(a)示出了其中与次系统CRSa使用同频资源CH1的主系统(或主系统参考点)只有一个、即PS1的情况。在此情况下，当次系统CRSa释放频谱资源CH1作为剩余频谱资源时，为了确定与CH1的对应的次系统集合，可以优先选择在次系统CRSa的可移动范围内的、相比CRSa远离PS1的位置的次系统构成与剩余频谱资源CH1对应的次系统集合。如图7a所示，例如，可以在以释放剩余频谱资源CH1的次系统CRSa为圆心、以符合标准的运动半径r(例如，可以是移动距离门限(例如ECC Report 186中规定的50m))为半径的圆内，选择相比次系统CRSa更远离主系统PS1的次系统CRSb构成与剩余频谱资源CH1对应的次系统集合。
图7(b)示出了与次系统CRSa使用同频资源CH1的主系统(或主系统参考点)包括多个、例如PS1、PS2、PS3的情况。在此情况下，可以通过分别求得次系统CRSa对PS1、PS2、PS3中的每个主系统(或主系统参考点)的可移动范围，再取重叠区域内面积最大的一个圆作为次系统CRSa的可移动范围，并且选择该可移动范围内的次系统构成与剩余频谱资源CH1对应的次系统。如图7(b)所示，次系统CRSb不处于CRSa可移动范围内，所以不选择其构成与剩余频谱资源CH1对应的次系统集合。
为了确保在此情况下确定的次系统集合中的次系统在使用剩余频谱资源时对主系统的干扰在主系统的干扰范围内，根据本公开，次系统集合确定模块1021还配置为基于对所确定的次系统集合中各个次系统在使用剩余频谱资源时对主系统的干扰的计算，确定将剩余频谱资源调整为由该次系统使用时对主系统造成的干扰是否在主系统的允许范围内，并且在所述次系统集合中去除对主系统造成的干扰超出主系统的允许范围的次系统。例如，频谱管理装置1 可以将次系统集合确定模块1021确定的次系统集合的相关信息发送给地理位置数据库，由地理位置数据库对所确定的次系统集合中各个次系统在使用剩余频谱资源时对主系统的干扰进行计算，并将计算结果反馈给频谱管理装置1，以便次系统集合确定模块1021基于该计算结果在所述次系统集合中去除对主系统造成的干扰超出主系统的允许范围的次系统。
通过如上所述的验证操作，可以确保在将次系统集合中的次系统调整为使用与该次系统集合对应的剩余频谱资源时，对主系统造成的干扰不会超过其允许的范围。
以上描述的是基于各个次系统相对于主系统的可移动范围的信息确定次系统集合，如上所述，相比于针对频谱管理装置1管理的每个次系统进行干扰计算，基于次系统的可移动范围确定次系统集合能够显著缩小计算范围，降低计算量。
此外，对于每个次系统，由于分配资源到达时间(其取决于请求频谱资源的时间)不同，当时网络中其它节点的资源分配不同，导致其所分配资源的差异。
根据本公开的另一实施例，在剩余频谱资源为次系统新释放的频谱资源的情况下，次系统集合确定模块1021也可以被配置为基于各个次系统的使用频谱被分配时的时间信息，选择构成所述次系统集合的次系统。
地理位置数据库发送给次系统和频谱管理装置的使用频谱信息中可以包括次系统当前使用的频谱资源被分配的时间戳，标记次系统获得当前使用的频谱资源的时间Tlatest。次系统集合确定模块1021可以基于次系统获得当前使用的频谱资源的时间Tlatest选择次系统构成与剩余频谱资源对应的次系统集合。
下面结合图8详细描述次系统集合确定模块1021基于各个次系统的使用频谱被分配时的时间信息，选择构成与剩余频谱资源对应的次系统集合中的次系统的具体处理。
图8示出了一个例子，对于三个次系统CRSb、CRSa、CRSc，其当前的使用频谱被分配的时间戳在时间轴上顺次排序，其中次系统CRSa的使用频谱CH1被分配给CRSa的时间晚于次系统CRSb的使用频谱CH2被分配给CRSb的时间、早于次系统CRSc的使用频谱CH3被分配给CRSc的时间。在次系统 CRSa释放其使用频谱CH1而CH1不属于CRSb和CRSc的可用频谱的情况下，由于次系统CRSb被分配其当前使用频谱的时间早于次系统CRSa的使用频谱CH1被分配的时间表明CRSb在分配其当前使用频谱时已经考虑了频谱资源CH1、但经过计算确定CRSb使用CH1对主系统的干扰不符合条件从而确定CRSb不使用CH1，而由于次系统CRSc被分配其当前使用频谱的时间晚于次系统CRSa的使用频谱CH1被分配的时间，次系统CRSc未被分配频谱资源CH1的原因可能是由于次系统CRSa正在使用频谱资源CH1，因此，次系统CRSc相比次系统CRSb具有更大的概率能够使用次系统CRSa释放的谱资源CH1，即次系统CRSc在使用频谱资源CH1时对主系统造成的干扰相比次系统CRSb具有更大的概率在主系统的干扰阈值范围之内。
因此，根据本公开，次系统集合确定模块1021被配置为在该频谱管理装置所管理的次系统中，选择其使用频谱被分配时间晚于释放该剩余频谱资源的次系统被分配该剩余频谱资源的时间的次系统，构成与该剩余频谱资源对应的次系统集合。
为了确保在此情况下确定的次系统集合中的次系统在使用剩余频谱资源时对主系统的干扰在主系统的干扰范围内，根据本公开，与基于各个次系统相对于主系统的可移动范围的信息选择构成该次系统集合的次系统类似，次系统集合确定模块1021也基于对所确定的次系统集合中各个次系统在使用剩余频谱资源时对主系统的干扰的计算，确定将剩余频谱资源调整为由该次系统使用时对主系统造成的干扰是否在主系统的允许范围内，并且在所述次系统集合中去除对主系统造成的干扰超出主系统的允许范围的次系统。与上述基于可移动范围的信息选择次系统类似，频谱管理装置1可以将次系统集合确定模块1021确定的次系统集合的相关信息发送给地理位置数据库，由地理位置数据库对所确定的次系统集合中各个次系统在使用剩余频谱资源时对主系统的干扰进行计算，并将计算结果反馈给频谱管理装置1，以便次系统集合确定模块1021基于该计算结果在所述次系统集合中去除对主系统造成的干扰超出主系统的允许范围的次系统。
虽然以上分别针对基于各个次系统相对于主系统的可移动范围的信息确定次系统集合以及针对基于各个次系统的使用频谱被分配时的时间信息确定 次系统集合进行了描述，但是可以理解，也可以将两种方式结合起来使用。更具体地，可以分别针对上述两种方式确定次系统集合，并将所确定的次系统集合合并构成最终的次系统集合，基于该最终的次系统集合由判定模块1022执行判定。
在获得了与剩余频谱资源对应的次系统集合之后，判定模块1022可以基于次系统集合中包含请求频谱资源的次系统的判断，来确定对各个次系统的频谱调整；如果次系统集合中不存在请求频谱资源的次系统，则将次系统集合中包括的每一个次系统当前使用的频谱资源作为所述剩余频谱资源；重复次系统集合确定模块1021和判定模块1022的操作，直到新确定的次系统集合中包括请求频谱资源的次系统为止，从而可以确定各个次系统的频谱调整。也就是说，根据本公开，以剩余频谱资源为起点，首先确定该剩余频谱资源对应的次系统集合，然后以次系统集合中的每个次系统所使用的频谱资源作为剩余频谱资源确定与每个剩余频谱资源对应的次系统集合，逐级确定次系统集合，直到次系统集合中包括请求频谱资源的次系统为止，即将请求频谱资源的次系统作为次系统集合确定模块1021操作的终点。
由于在逐级确定次系统集合的过程中，如果重复次系统集合确定操作的次数达到一定数量后仍未找到请求频谱资源的次系统，则不太可能为请求频谱资源的次系统找到频谱调整方案。基于此，为了控制频谱转移方案的设计规模和复杂度，根据本公开的优选实施例，处理电路被配置为如果在重复次系统确定模块1021和判定模块1022的操作的重复次数达到预定阈值的情况下、各个次系统集合中仍不包括所述请求频谱资源的次系统，确定不为所述请求频谱资源的次系统分配频谱资源。
下面结合图9详细描述调整确定单元的另一种示例性结构。
如图9所示，除了与调整确定单元102类似地包括：次系统集合确定模块1021和判定模块1022，调整确定单元102’还包括：频谱调整图生成模块1023，基于各个次系统集合建立有向图作为频谱转移图，并根据所述频谱转移图、利用深度优先搜索或广度优先搜索确定关于所述频谱调整的频谱调整信息，其中所述有向图通过以下方式建立：将释放该剩余频谱资源的次系统或者频谱管理装置作为尾节点、将与该剩余频谱资源对应的次系统集合中的每个次 系统为头节点，将所述剩余频谱资源作为连接尾节点和头节点的有向边的权值。根据本公开，在剩余频谱资源为系统中未被使用的频谱资源或者未达用户使用上限的其他频谱资源时，在建立有向图时，可以以频谱管理装置作为源节点。
图10示出了频谱调整图的一条有向路径的一个示例，其中Vs表示有剩余频谱资源的节点(可以是释放该剩余频谱资源的次系统，如果在剩余频谱资源为无线通信系统中未被使用的频谱资源或者未达用户使用上限的其他频谱资源时，则可以用一个表示频谱管理装置的逻辑节点表示)；Vi、Vj表示与剩余频谱资源对应的次系统集合中的次系统、Vj表示与Vi所表示的剩余频谱资源对应的次系统集合中的次系统，Vd表示请求频谱资源的次系统，其中以Vi为尾节点、Vj为头节点的有向边为例，该有向边表示可以将尾节点表示的次系统当前使用的频谱资源转移至头节点表示的次系统(在此情况下，尾节点表示的次系统释放其当前使用的频谱资源)，即进行上述频谱转移对主系统造成的干扰在主系统的允许范围内。确定的频谱调整方案则表示为频谱调整图G上从Vs到Vd的一条有向路径。该有向路径的跳数表示频谱转移的次数，也即为需要重配置的次系统的个数。所以一种较优的频谱转移方案为从Vs到Vd的一条最短有向路径。该最短有向路径可以通过例如广度优先搜索(Breadth First Search,BFS)或深度优先搜索(Depth First Search,DFS)等方法求出。
基于频谱调整图生成模块1023生成的频谱调整图，调整确定单元102’可以确定最优频谱调整方案，并将关于该最优频谱调整方案的频谱调整信息发送给相应的次系统，以便各个次系统基于该频谱调整信息对其频谱使用进行调整。在确定了频谱调整方案、从而确定了频谱调整信息之后，频谱管理装置可以基于频谱调整信息生成重配置请求，并将频谱调整信息与重配置请求一起发送给相应的次系统。频谱调整信息例如包括：要进行频谱调整操作的次系统的标识、新分配给该次系统的频谱资源的信息和/或该次系统要释放的频谱资源的信息。
相应的次系统在接收到重配置请求之后，响应于重配置请求、根据频谱调整信息对其使用的频谱资源进行重新配置。
图11是示出根据本公开实施例的频谱管理装置的另一示例的框图。如图 10所示，除了如上所述的处理电路10之外，频谱管理装置2还包括：通信单元20，被配置为发送处理电路10确定的关于频谱调整的频谱调整信息，该频谱调整信息包括：要进行频谱调整操作的次系统的标识、新分配给该次系统的频谱资源的信息和/或该次系统要释放的频谱资源的信息。根据本公开，通信单元20向涉及频谱调整的次系统发送频谱调整信息以便次系统根据该频谱调整信息对其频谱使用进行调整，并且更新各自的可用频谱列表以及使用频谱列表。除了相应的次系统之外，通信单元20还被配置为将该频谱调整信息报告给地理位置数据库，以便地理位置数据库更新其所维护的各个次系统的可用频谱列表和/或使用频谱列表。

对应于本公开的频谱管理装置，本公开还提供一种频谱管理方法和用于包括主系统和次系统的无线通信系统的方法。下文中，在不重复上文中已经讨论的一些细节的情况下给出这些方法的概要，但是应当注意，虽然这些方法在描述用于无线通信系统的频谱管理装置的过程中公开，但是这些方法不一定采用 所描述的那些部件或不一定由那些部件执行。例如，用于无线通信系统的频谱管理装置、次系统和地理位置数据库的实施方式可以部分地或完全地使用硬件和/或固件来实现，而下面讨论的方法可以完全由计算机可执行的程序来实现，尽管这些方法也可以采用用于无线通信系统的频谱管理装置、次系统和地理位置数据库的硬件和/或固件。

在S2，响应于该频谱资源请求，由地理位置数据库确定是否触发频谱调整操作，其例如对应于根据上述实施例描述的地理位置数据库中处理电路的调整触发操作(该操作例如也可以由根据本公开实施例的频谱管理装置的调整触发单元来执行)，其具体操作在此不再赘述。
在S3，在确定触发对次系统地频谱调整操作后，向频谱管理装置发送各 个次系统的频谱使用信息和频谱调整能力信息，该频谱使用信息对应于已经分配给各个次系统使用的使用频谱相关信息，该频谱调整能力信息对应于该次系统是否支持频谱调整操作的相关信息；其例如对应于根据上述实施例描述的地理位置数据库的通信单元的操作来执行，具体操作在此不再赘述。
在S4，频谱管理装置接收其所管理的次系统的频谱使用信息和频谱调整能力信息，并且基于所述频谱使用信息和所述频谱调整能力信息，确定对该频谱管理装置所管理的次系统的频谱调整，以使得各个次系统的频谱使用对无线通信系统中的主系统造成的干扰在主系统的允许范围内。具体地包括：在S4.1由频谱管理装置基于次系统频谱使用信息和所述频谱调整能力信息，确定与剩余频谱资源对应的次系统集合，并将所确定的次系统集合的信息发送给地理位置数据库，由地理位置数据库针对次系统集合中的每个次系统计算其对主系统的干扰并将计算结果返回频谱管理装置以及由频谱管理装置基于接收的计算结果，将对主系统的干扰超出主系统的允许范围的次系统从次系统集合中去除；S4.2，基于确定的次系统集合确定频谱调整方案。S4的处理例如对应于根据上述实施例描述的频谱管理装置的调整确定单元的频谱调整信息的操作、包括次系统集合确定模块和判定模块的相应操作，具体操作在此不再赘述。

在S6，次系统基于接收的频谱调整信息对其频谱使用进行重新配置。
虽然以上描述的是由地理位置数据库执行步骤S2的触发调整操作，但是以上关于频谱管理装置的实施例中所述，该触发调整操作也可以由频谱管理装置执行。
图21和图22示出了用于无线通信无线系统中的方法的流程图的更具体的示例。
如图21所示，在S1，请求频谱资源的次系统向地理位置数据库(或者频 谱管理装置)发送频谱资源请求；在S2，响应于该频谱资源请求，由地理位置数据库确定是否触发频谱调整操作；在S3，在确定触发对次系统地频谱调整操作后，向频谱管理装置发送各个次系统的频谱使用信息和频谱调整能力信息，该频谱使用信息对应于已经分配给各个次系统使用的使用频谱相关信息，该频谱调整能力信息对应于该次系统是否支持频谱调整操作的相关信息；在S4，基于所述频谱使用信息和所述频谱调整能力信息，确定对该频谱管理装置所管理的次系统的频谱调整；在S5，由频谱管理装置将关于频谱调整方案的频谱调整信息发送给地理位置数据库；在S5’中，由频谱管理装置将频谱调整方案的频谱调整信息发送给次系统，同时还可以向相应的次系统发送频谱调整请求；在S6，次系统基于接收的频谱调整信息对其频谱使用进行重新配置。除了在S4.1中的处理被具体描述为以下S4.1.a至S4.1.d之外，图21中的上述处理与图20示出的用于无线通信系统的方法的流程图类似。在图21所示的用于无线通信系统的方法，在S4.1.a，由频谱管理装置基于次系统的可移动范围的信息预估与剩余频谱资源对应的次系统集合；在S4.1.b，频谱管理装置向地理位置数据库发送确认预估的次系统集合是否合适的请求，即请求地理位置数据库计算预估的次系统集合中每个次系统在被调整为使用新释放的频谱资源时对主系统的干扰；在S4.1.c，由地理位置数据库响应于频谱管理装置的请求，对预估的次系统集合中的次系统被调整为使用新释放的频谱资源时对主系统的干扰进行计算，并且在4.1.d将计算结果或者基于该干扰值确定干扰是否在主系统的允许范围内的确认结果发送给频谱管理装置。
图22与图21类似，除在图21的S4.1.a中，由频谱管理装置是基于次系统的可移动范围的信息来预估与剩余频谱资源对应的次系统集合；而在图22的S4.2.a中，是由频谱管理装置基于次系统被分配其使用频谱信息的时间来预估与剩余频谱资源对应的次系统集合的。出于简洁的目的，在此省略了对图22中其他步骤的详细描述。
与现有技术相比，根据本公开实施例的频谱管理设备、方法、地理位置数据库、共存发现装置和次系统至少具有以下有益效果之一：根据次系统的频谱使用信息和频谱调整能力信息寻找剩余频谱资源与请求频谱资源的次系统之间的频谱转移的方案，通过实施该方案对涉及的次系统进行重配置以便实现在 尽可能少的重配置开销的情形下实现接入尽可能多的次系统，达到对资源高效利用。
[具体应用]
实例一
当前，涌现出大量标准通过共存管理解决资源利用率低效的问题，IEEE P802.19a就是其中之一。用于该标准的频谱管理系统的主要逻辑实体包括：频谱管理服务器(Spectrum Management Database,SMD):其对应于根据本发明实施例的频谱管理装置的调整确定单元，用于根据位置信息为GCO分配频谱资源；共存发现与信息服务器(coexistence discovery and information server(CDIS))：其对应于根据本公开实施例的共存发现装置，用于为共存管理器(coexistence managers(CM))发现哪些地理位置能力对象(Geolocation Capability Object(GCO))会影响其服务的GCO的性能，触发CM进行共存管理；共存管理器，其例如对应于根据本公开实施例的频谱管理装置，其用来提供共存管理；地理位置能力对象，其例如对应于根据本公开实施例的次系统，表示单一设备或由多个设备构成的网络，这些设备基于获得认证的地理位置能力进行工作，从CM获取共存服务。
本发明同样可以应用于IEEE P802.19a，对应规则是：SMD负责为GCO分配频谱资源或进行频谱资源可用性的重计算，CDIS负责共存发现，触发CM确定频谱转移方案，CM根据结果向GCO发起调整请求，GCO根据该请求完成重配置。其中GCO进一步分为不同优先等级，低优先等级的GCO获得资源必须满足对高优先等级GCO的聚合干扰控制在其可以承受的范围内。
特别注意的是，因为CM和SMD之间没有直接的信息传输接口。图23示出了根据本公开的应用示例的频谱管理系统的流程图。当CM需要获得频谱转移条件计算结果(即如上所述的逐级获取与剩余频谱资源对应的次系统集合(从而建立频谱调整图))时。如图21所示，首先CM将频谱转移条件计算请求(例如，该请求中包含频谱请求组信息参数(由参数specRequestModification表示)，进一步该参数包含频谱请求组的ID(由groupIndex表示)，以及所需检验的频谱(由spectrumCheck表示))下发给GCO，GCO直接向SMD申请该重新计算，SMD进行频谱转移条件计算，并将计算结果发回给GCO，由GCO将 该结果上传给CM。
实例二
该方法同样能用于频谱访问系统(Spectrum Access System,SAS)3.5GHz系统多层次共存系统管理。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，需要保护其不受公民宽带无线服务用户(Citizens Broadband Radio Service users)的有害干扰，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)；公民宽带无线服务又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，需要保护PAL不受到来自GAA的有害干扰。当频谱资源管理器管理incumbent，PAL和GAA之间资源共存时同样可以使用该方法以提高资源使用效率。例如，某一新GAA加入时，如果由于资源分配结果而无法直接获得可用资源，可以通过保护incumbent和PAL的前提下，尽可能少的调整GAA间的资源分配实现对新GAA的接入。
