Description

频谱资源管理装置和方法 技术领域
本发明一般涉及无线通信领域，更具体地涉及包括用于存在多级通信系统的区域的频谱资源管理装置和方法。
背景技术
随无线通信系统的进化，用户对高品质、高速度、新服务的服务需求越来越高。无线通信运营商与设备商需要不断改进系统以达到用户的要求。这需要大量的频谱资源(例如，可以用时间、频率、带宽、可容许最大发射功率等参数来进行量化)以支持新服务和满足高速通信需求。有限的频谱资源已经分配给固定的运营商和服务，新的可供使用的频谱或是非常稀少或是价格昂贵。
在这种情况下，人们提出了动态频谱利用的概念，即动态地利用那些已经分配给某些服务但是却没有被充分利用的频谱资源。例如，动态地利用数字电视广播频谱上某些没有播放节目的频道的频谱或者相邻频道的频谱，在不干扰电视信号接收的情况下，进行无线移动通信。在这个应用示例中，由于电视广播频谱本身就是分配给电视广播系统使用的，因此电视广播系统是主系统(primary system)，电视机是主用户(primary user)。移动通信系统是在保证对主系统不造成干扰的情况下使用主系统频谱资源的通信系统，因此移动通信系统是次系统(secondary system)移动通信系统中的接收机是次用户(secondary user)。这里所述的主系统可以是指那些有频谱使用权的系统，例如电视广播系统；而次系统则是没有频谱使用权、只在主系统不使用其所拥有的频谱的时候适当地使用该频谱的系统。
另外，主系统和次系统也可以是同时具有频谱使用权的系统，但是在频谱使用上具有不同的优先级别，即具有不同的频谱资源使用权限。例如，运营商在部署新的基站以提供新服务的时候，已有基站及其提供的服务具有频谱使用优先权。主系统包含主用户基站(primary user base station)与主用户，而次系统包含次用户基站(secondary user base station)与次用户。
当次系统为紧急服务或者具有一定的通信服务质量(QoS)要求时，可以将原有的主系统作为第一级系统(也称第一级通信系统)，将这些次系统作为第二级系统(也称第二级通信系统)。那些没有服务质量要求或者为民用业务的次系统作为第三级系统(也称第三级通信系统)。也就是说，不同级别的系统具有不同的频谱使用权限。例如，这里的第一级系统具有比第二级系统和第三级系统高的频谱使用权限，第二级系统具有比第三级系统高的频谱使用权限，第三级系统的频谱使用权限最低。同一预定区域内的各级通信系统可能由同一频谱资源管理装置进行管理，该预定区域作为该频谱资源管理装置的管理区域。
这种多级通信系统共存的通信方式要求较低权限的通信系统对较高权限的通信系统进行保护，较低权限通信系统的应用对较高权限通信系统的应用不应造成干扰，或者较低权限通信系统的频谱利用所造成的影响能被控制在较高权限通信系统容许的范围之内。
目前，对于对具有多个频谱使用级别的系统的管理是通过数据库实现的。这个数据库存储主系统所能容许的干扰门限。同一管理区域内的次系统在开始利用主系统的频谱之前首先要访问该数据库并提交次系统的频谱利用特性信息，例如位置信息、频谱发射模板(spectrum emission mask)、传输带宽和载波频率等等。然后，数据库根据次系统的状态信息计算次系统对主系统的干扰量，并根据所计算的当前频谱利用特性下的次系统对主系统的干扰量来计算当前频谱利用特性下的次系统的可用频谱资源。
发明内容
然而，当有具有多个频谱使用权限的系统共同使用频谱资源时，特别地，对第二级系统的频谱使用，在考虑到第二级系统对第一级系统的保护的前提下，需要考虑来自第二级系统、第三级系统甚至是第一级系统的干扰。而且，由于需要考虑第二级系统和第三级系统对第一级系统产生的聚合干扰，第二级系统的可用频谱资源上限不仅取决于第二级系统对第一级系统的干扰，同时也取决于第三级系统对第一级系统的干扰。因此，本申请人根据上述发现而做出了本发明。本发明可以扩展到多个频谱使用级别的系统共存的场景。

具体实施方式
下面参照附图来说明本发明的实施例。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。
下面结合图1来描述根据本发明实施例的频谱资源管理装置的配置。图1是示出根据本发明实施例的频谱资源管理装置的配置示例的框图。
如图1所示，频谱资源管理装置100可包括可用资源确定单元102、资源利用调整单元104和可用资源更新单元106。
可用资源确定单元102可以用于确定目标通信系统的可用频谱资源，使得在目标通信系统在所述可用频谱资源的范围内工作、并且频谱资源管理装置100的管理区域内的较低权限通信系统在该较低权限通信系统的可用频谱资源的范围内工作时，目标通信系统和较低权限通信系统对该管理区域内的较高权限通信系统产生的聚合干扰不超过该较高权限通信系统的干扰门限。其中，较高权限通信系统具有比目标通信系统高的频谱使用权限，较低权限通信系统具有比目标通信系统低的频谱使用权限。较低权限通信系统的可用频谱资源可以是当前已为该较低权限通信系统确定的频谱资源。
这里及以下的例子中，目标通信系统为认知无线电技术中的次系统，机会性地利用例如非授权频谱进行工作，同时保证对该频谱的具有常规使用权的主系统造成的干扰在主系统的容许的范围之内。
在频谱资源管理装置100的管理区域内可以同时存在多个频谱使用级别的系统。也就是说，多个频谱使用级别的系统可以共存。
下面结合图2来描述多个频谱使用级别的系统共存的场景的示例。图2是示出根据本发明实施例的多个频谱使用级别的系统共存的场景的示意图。
如图2所示，在频谱资源管理装置1或2的管理区域内存在三个频谱使用权限级别的系统。这里，频谱资源管理装置1和2可以由频谱资源管理装置100来实施。其中以实心的三角形表示第一级系统，以实心的圆形表示第二级系统，以空心的圆形表示第三级系统。作为一个具体的示例，三个级别的系统都将利用广播电视频段的频谱资源进行通信，第一级系统例如是对广播电视频段资源拥有常规使用权的广播电视系统(在一些例子中称为主系统)，第二级系统和第三级系统例如是期望利用广播电视频段资源的蜂窝通信系统和无线保真(wireless fidelity，wifi)系统(在一些例子中称为次系统)。作为另一个具体的示例，第一级系统例如是现有的气象雷达系统，这些雷达系统具有很好的接收机，所以通信系统可以在其周围使用相同的频段，但是会受到来自雷达的干扰；第二级系统例如是共享雷达频段为用户提供小区服务的无线通信运营商的通信系统，这些小区服务有通信质量要求，因此这些通信系统对频谱的使用要求在保护雷达系统的前提下，保证通信质量；第三级系统例如是共用雷达频段的wifi系统。
这些具有不同频谱使用权限级别的系统都与其所在的管理区域的频谱资源管理装置1或2进行数据交换。在频谱资源管理装置1或2的管理区域中，假定第一级系统已经使用某一个频段并且将频谱利用信息，例如第一级系统的位置、覆盖范围、需要进行干扰控制的位置以及所能容忍的干扰门限等存储在频谱资源管理装置例如地理位置数据库(Geo-Location DataBase，GLDB)中。第二级系统和第三级系统动态地访问频谱资源管理装置。频谱资源管理装置可以根据第二级系统和第三级系统对第一级系统的干扰以第一级系统的干扰门限来计算第二级系统或第三级系统的可用频谱资源。本领域技术人员应当理解，可以采用各种方法来计算次系统的可用频谱资源。例如，例如可以采用参考文献1(ECC REPORT 159,“TECHNICAL AND OPERATIONAL REQUIREMENTS FOR THE POSSIBLE OPERATION OF COGNITIVE RADIO SYSTEMS IN THE‘WHITE SPACES’OF THE FREQUENCY BAND 470-790MHz”，Cardiff，2011年1月)中说描述的电视频段无线通讯系统可用频谱资源的计算方式来计算次系统的可用频谱资源。第二级系统的频谱利用需要达到期望的通信服务质量。第二级系统的通信服务质量的计算依赖于第一级系统以及其他的第二级系统对目标第二级系统所产生的干扰。第三级系统 没有常规频谱使用权限，而是机会性地在不干扰其他高级别系统的情况下使用频谱资源。
本公开中以第二级系统为目标系统的具体示例，针对第二级系统的频谱利用，提出了在满足对第一级系统(较高权限通信系统)的干扰门限前提下，频谱资源管理装置控制第二级系统和第三级系统(较低权限通信系统)的频谱使用使得第二级系统达到期望的通讯质量。应当理解，虽然上文中将第一级系统举例为主系统，但是第一级系统也可以例如是对广播电视频段资源具有更高频谱使用权的次系统，而且根据本发明实施例的装置和方法可以扩展到更多个频谱使用级别的系统共存的场景。
由于多级频谱使用权限的系统共存，各级频谱使用权限的系统会相互造成干扰。因此，在上述的实施例中，在确定目标通信系统的可用频谱资源时，考虑在目标通信系统在其可用频谱资源的范围内工作、并且频谱资源管理装置100的管理区域内的较低权限通信系统在该较低权限通信系统的可用频谱资源的范围内工作时，目标通信系统和该较低权限通信系统对该管理区域内的较高权限通信系统产生的聚合干扰不超过该较高权限通信系统的干扰门限。应当理解，这里的较低权限通信系统不限于单个较低权限通信系统，而是指一组较低权限通信系统。例如可以将频谱资源管理装置100的管理区域内的比目标通信系统级别低的所有通信系统作为该组较低通信系统的成员。另外，如果还存在和目标通信系统同级的其他通信系统，还可考虑同级通信系统的干扰来计算聚合干扰；如果在所述较高级别通信系统和目标通信系统的级别之间还存在其他级别的通信系统，还可考虑其他级别的通信系统的干扰来计算聚合干扰。在这里及以下的描述中将应用本发明的场景简化为仅有三级通信系统，以免模糊重点，便于描述。
此外，在本发明的一个较佳的示例中，对于频谱资源管理装置100管理区域内(属于管理装置100的管理对象)的目标通信系统，频谱资源管理装置100还控制向目标通信系统的资源分配，使之对管理区域以外的较高权限通信系统的干扰不超过该较高权限通信系统的干扰门限。例如目标通信系统与该管理区域以外的同级或较低权限通信系统对该管理区域以外的较高权限通信系统的聚合干扰不超过其干扰门限。例如频谱资源管理装置100与相邻区域的频谱资源管理装置交互关于请求资源的目标通信系统的信息，具体例如包括指示级别的信息的频谱利用特性等，并且从 该相邻区域的频谱资源管理装置获取在保护其管理区域内的较高权限通信系统情况下的目标通信系统的可用频谱资源，并基于该可用频谱资源进行资源分配/调整。
例如，在图2所示的场景中，频谱资源管理装置2确定目标第二级系统的可用频谱资源。该目标第二级系统可以是频谱资源管理装置2的管理区域内的第二级系统；也可以是频谱资源管理装置2的管理区域之外的第二级系统，例如是频谱资源管理装置1的管理区域中的第二级系统。第一级系统受到来自第二级系统和第三级系统的聚合干扰。假定频谱资源管理装置2的管理区域中的第一级系统的干扰门限为10mw，也就是说，到达该第一级系统的聚合干扰不能超过10mw。频谱资源管理装置2的管理区域中的第三级系统对第一级系统产生3mw的干扰。因此目标第二级系统所能产生的干扰量不能超过7mw。据此，可以确定目标第二级系统的可用频谱资源(在下文中也称为当前可用频谱资源)，例如最大传输功率为(7mw×路径损耗)。
进一步参考图2的场景，如果去除第三级系统对第一级系统产生的3mw的干扰，则可以容许目标第二级系统相应地提升最大传输功率，例如3mw×路径损耗。该提升量是去除该管理区域内第三级系统对第一级系统的干扰而为目标第二级系统带来的可用频谱资源的提升量。也就是说，在第三级系统对第一级系统不产生干扰的情况下，目标第二级系统的最大传输功率为10mw。据此，可以确定目标第二级系统的最大可用频谱资源(在下文中也称为调整后预计可用频谱资源)。
由于较低权限通信系统的可用频谱资源减少，其对较高权限通信系统的干扰也会相应减小。在较高权限通信系统的干扰门限不变的情况下，由于较低权限通信系统产生的干扰减小，可容许目标通信系统产生的干扰可以增大。相应地，可以容许目标通信系统使用更多的频谱资源，从而为目标通信系统带来可用频谱资源的提升量。根据以上发现，在本发明的实施例中，可以通过调整(例如减小或取消)较低权限通信系统的可用频谱资源来提升目标通信系统的可用频谱资源。此外，相邻区域的频谱资源管理装置可以和频谱资源管理装置100交互有关提升量的信息，以便频谱资源管理装置100确定对目标通信系统的资源分配。
相应的，频谱资源管理装置100也可以按照上述的方式调整其管理区域内的较低权限通信系统的可用频谱资源来提升目标通信系统的可用频谱资源。返回参考图1，频谱资源管理装置100中的资源利用调整单元104 可以减少频谱资源管理装置100的管理区域内的较低权限通信系统的可用频谱资源，使得较低权限通信系统在减少后的可用频谱资源的范围内工作时对目标通信系统产生的干扰不超过目标通信系统的干扰门限。
频谱资源管理装置100可以使用任何适当的方法来获取目标通信系统的干扰门限。例如，频谱资源管理装置100可以从目标通信系统或目标通信系统所属的频谱资源管理装置接收其干扰门限。再例如，频谱资源管理装置100可以通过对目标通信系统的频谱资源使用情况进行仿真来确定目标通信系统的干扰门限。
在装置100中，可用资源更新单元106可以根据较低权限通信系统的减少后的可用频谱资源来更新目标通信系统的可用频谱资源，使得在目标通信系统在更新后的可用频谱资源的范围内工作、并且较低权限通信系统在减少后的可用频谱资源的范围内工作时，所产生的对较高权限通信系统的聚合干扰不超过较高权限通信系统的干扰门限。更具体而言，可以将由于较低权限通信系统的可用频谱资源减少而为目标通信系统带来的可用频谱资源的提升量增加到目标通信系统的当前可用频谱资源上。在另一实施例中，可用资源更新单元106还可以更新调整后(例如减少后)的较低权限通信系统的可用频谱资源。
这样，可以在较低权限通信系统对目标通信系统进行保护的同时，提高目标通信系统的可用频谱资源的量。
在上述和以下实施例中，除非特别说明，否则目标通信系统可以是位于频谱资源管理装置100的管理区域内的通信系统，也可以是位于频谱资源管理装置100的管理区域之外的通信系统。
除了通过减小较低权限通信系统的可用频谱资源来提升目标通信系统的可用频谱资源之外，如果目标通信系统设定来排他区域，则频谱资源管理装置还可以停止在排他区域中的较低权限通信系统，以实现对目标通信系统的保护。
在本发明的一个实施例中，资源利用调整单元104可以停止频谱资源管理装置100的管理区域内的在目标通信系统的排他服务区域中工作的较低权限通信系统，以对目标通信系统进行保护。
在停止排他服务区域中的较低权限通信系统之后，该被停止的较低权限通信系统不再对目标通信系统产生干扰，同时也不再对较高权限通信系统产生干扰。相应地可以为目标通信系统带来可用频谱资源的提升量。因 此，可用资源更新单元106可以根据频谱资源管理装置100的管理区域中的余下的较低权限系统的当前可用频谱资源来更新目标通信系统的可用频谱资源，使得在目标通信系统在更新后的可用频谱资源的范围内工作、并且余下的较低权限通信系统在其当前可用频谱资源的范围内工作时，所产生的对较高权限通信系统的聚合干扰不超过较高权限通信系统的干扰门限。
由于目标通信系统有一定的通信服务质量要求，因此为目标通信系统确定的可用频谱资源需要满足(例如等于或高于)其所需频谱资源，以使目标通信系统在使用该可用频谱资源通信时能够实现所需的服务质量。
根据本发明的另一个实施例，资源利用调整单元104还用于在目标通信系统的更新后的可用频谱资源低于目标通信系统的所需频谱资源的情况下，再次减少较低权限通信系统的可用频谱资源。可用资源更新单元106还用于在目标通信系统的更新后的可用频谱资源低于目标通信系统的所需频谱资源的情况下，根据较低权限通信系统的当前减少后的可用频谱资源来再次更新目标通信系统的可用频谱资源，使得在目标通信系统在当前更新后的可用频谱资源的范围内工作、并且所述较低权限通信系统在当前减少后的可用频谱资源的范围内工作时，所产生的对较高权限通信系统的聚合干扰不超过该较高权限通信系统的干扰门限，直到目标通信系统的当前更新后的可用频谱资源等于或高于目标通信系统的所需频谱资源。
频谱资源管理装置100的上述及以下各个部件可以是集中于一个实体中(以硬件或软件或软硬件结合的形式)，也可以是分布地存在于多个实体中。在本公开的一些地方称频谱资源管理装置100为一个系统。例如，可用资源确定单元102、资源利用调整单元104和可用资源更新单元106都可以集中设置于例如欧洲电信标准化协会(European Telecommunications Standards Institute，ETSI)制定的可重配置无线电系统(Reconfigurable Radio Systems)标准中的GLDB设备当中。也可以是可用资源确定单元102和可用资源更新单元106设置于GLDB中，而资源利用调整单元104设置于其他的用于使能次系统对非授权频谱使用的物理/逻辑实体中，例如设置于用于解决多个次系统共存问题而做出协调决定的共存管理器(coexistence manager)当中。
频谱资源管理装置100可以通过各种方式获得目标通信系统的所需频谱资源。例如，可以从目标通信系统或者从目标通信系统所属的频谱资源管理装置获得该目标通信系统的所需频谱资源。再例如，可以根据目标 通信系统所受到的干扰来计算该目标通信系统的所需频谱资源。以下结合图3来描述由频谱资源管理装置来计算目标通信系统的所需频谱资源的实施例。
图3示出根据本发明另一实施例的频谱资源管理装置的配置示例的框图。如图3所示，频谱资源管理装置300包括可用资源确定单元302、资源利用调整单元304、可用资源更新单元306和所需资源确定单元308。其中，可用资源确定单元302、资源利用调整单元304和可用资源更新单元306的配置分别与图1中所示的频谱资源管理装置100中的可用资源确定单元102、资源利用调整单元104和可用资源更新单元106的配置相同，因此其具体细节在此不再赘述。下面，详细描述频谱资源管理装置300中的所需资源确定单元308。
所需资源确定单元308可以根据频谱资源管理装置300的管理区域内的较高权限通信系统和相同权限通信系统对目标通信系统的干扰以及目标通信系统的服务质量(QoS)要求来计算目标通信系统的所需频谱资源。本文中，相同权限通信系统指的是具有与目标通信系统相同的频谱使用权限级别的通信系统。
所需资源确定单元308可以使用现有的各种适当的方法来计算目标通信系统的所需频谱资源。作为示例而不是限制，例如，可以根据较高权限通信系统和相同权限通信系统对目标通信系统的干扰、以及目标通信系统的服务质量要求例如其服务范围边缘所需的信噪干扰比来计算目标通信系统的服务范围边缘所需的信号传输功率，并根据该信号传输功率和目标通信系统到其服务范围边缘的路径损耗来计算目标通信系统的发射机所需的最小传输功率。
由以上可知，较高权限通信系统和相同权限通信系统对目标通信系统的干扰会影响目标通信系统的所需频谱资源。因此，在通过减小较低权限通信系统的可用频谱资源来提升目标通信系统的可用频谱资源并不能满足目标通信系统的所需频谱资源的情况下，可以考虑减小相同权限通信系统对目标通信系统的干扰来降低目标通信系统的所需频谱资源。较高权限通信系统具有比目标通信系统高的频谱资源使用权限，因此无法调整较高权限通信系统的频谱使用以减小对目标通信系统的干扰。以下结合图4和图5来描述频谱资源管理装置通过调整相同权限通信系统对目标通信系统的干扰来提升目标通信系统的可用频谱资源的实施例。
图4是示出根据本发明另一实施例的频谱资源管理装置的配置示例 的框图。如图4所示，频谱资源管理装置400包括可用资源确定单元402、资源利用调整单元404、可用资源更新单元406、所需资源确定单元408和干扰调整单元410。其中，可用资源确定单元402、资源利用调整单元404和可用资源更新单元406的配置分别与图1中所示的频谱资源管理装置100中的可用资源确定单元102、资源利用调整单元104和可用资源更新单元106的配置相同，因此其具体细节在此不再赘述。下面，详细描述频谱资源管理装置400中的所需资源确定单元408和干扰调整单元410。
干扰调整单元410可以在当前更新后的可用频谱资源仍然低于目标通信系统的所需频谱资源的情况下，减少频谱资源管理装置400的管理区域内的其他相同权限通信系统对目标通信系统的干扰。
干扰调整单元410可以使用现有的各种适当的方法来减少其他相同权限通信系统对目标通信系统的干扰。在一个示例中，干扰调整单元410可以利用现有的共存技术来减小目标通信系统与其他相同权限通信系统间的互相干扰。例如，干扰调整单元410可以通过发送频谱使用周期时间给其他相同权限通信系统以提供同步信息。在同步的基础上协调目标通信系统与其他相同权限通信系统的频谱使用以便减少相互间的干扰。干扰调整单元410可以根据目标通信系统和其他相同权限通信系统的数目、可用频谱资源、以及频谱资源使用区域的范围来确定目标通信系统和其他相同权限系统之间的频谱资源使用策略，以减小或避免目标通信系统和相同权限通信系统之间的干扰。另外，作为示例而非限制，频谱资源管理装置可以利用预定系统应用模型来计算目标通信系统和相同权限通信系统之间的干扰。
所需资源确定单元408可以根据频谱资源管理装置400的管理区域内的较高权限通信系统和相同权限通信系统对目标通信系统的干扰以及目标通信系统的服务质量要求，重新计算目标通信系统的所需频谱资源。所需资源确定单元408可以具有与图3中的频谱资源管理装置300中的所需资源确定单元308相同的配置，因此其具体细节在此不再赘述。
在图4的实施例中，在对较低权限通信系统的可用频谱资源进行调整之后考虑是否对相同权限通信系统对目标通信系统的干扰进行调整。在以下结合图5描述在对较低权限通信系统的可用频谱资源进行调整之前考虑是否对相同权限通信系统对目标通信系统的干扰进行调整的实施例。
图5是示出根据本发明另一实施例的频谱资源管理装置的配置示例的框图。如图5所示，频谱资源管理装置500包括可用资源确定单元502、 资源利用调整单元504、可用资源更新单元506、所需资源确定单元508和干扰调整单元510。其中，资源利用调整单元504和可用资源更新单元506的配置分别与图1中所示的频谱资源管理装置100中的资源利用调整单元104和可用资源更新单元106的配置相同，因此其具体细节在此不再赘述。下面，详细描述频谱资源管理装置500中的可用资源确定单元502、所需资源确定单元508和干扰调整单元510。
可用资源确定单元502除了具有与图1中所示的频谱资源管理装置100中的可用资源确定单元102相同的配置之外，还用于在资源利用调整单元504减少较低权限通信系统的可用频谱资源之前，确定在较低权限通信系统对较高权限通信系统不产生干扰的情况下，目标通信系统的最大可用频谱资源(调整后预计可用频谱资源)。根据以上描述可知，在较低权限通信系统对较高权限通信系统不产生干扰的情况下，可以为目标通信系统带来可用频谱资源的最大提升量。可用资源确定单元502最初确定的目标通信系统的可用频谱资源(如以所描述的可用资源确定单元102所确定的目标通信系统的可用频谱资源)加上该最大提升量，就是所确定的目标通信系统的最大可用频谱资源。
干扰调整单元510可以在目标通信系统的最大可用频谱资源低于目标通信系统的所需频谱资源的情况下，减少频谱资源管理装置500的管理区域内的相同权限通信系统对目标通信系统的干扰。干扰调整单元510可以具有与图4中的频谱资源管理装置400中的干扰调整单元410相同的配置，因此其具体细节在此不再赘述。
所需资源确定单元508可以根据频谱资源管理装置500的管理区域内的较高权限通信系统和相同权限通信系统对目标通信系统的干扰以及目标通信系统的服务质量要求，重新计算目标通信系统的所需频谱资源。所需资源确定单元508可以具有与图3中的频谱资源管理装置300中的所需资源确定单元308相同的配置，因此其具体细节在此不再赘述。
在本发明的另一个实施例中，频谱资源管理装置还可以包括接口单元，以用于与其他设备如目标通信系统通信。以下结合图6来描述具有接口单元的频谱资源管理装置的实施例。
图6是示出根据本发明另一实施例的频谱资源管理装置的配置示例的框图。如图6所示，频谱资源管理装置600包括可用资源确定单元602、资源利用调整单元604、可用资源更新单元606和接口单元612。其中，可用资源确定单元602、资源利用调整单元604和可用资源更新单元606 的配置分别与图1中所示的频谱资源管理装置100中的可用资源确定单元102、资源利用调整单元104和可用资源更新单元106的配置相同，因此其具体细节在此不再赘述。以下详细描述频谱资源管理装置600中的接口单元612。
在目标通信系统位于频谱资源管理装置600的管理区域内的情况下，接口单元612可以接收目标通信系统的频谱利用请求，该频谱利用请求中可以包含目标通信系统的频谱利用特性，例如目标通信系统的位置信息、频谱发射模板、传输带宽、载波频率、干扰门限、服务质量要求(指示频谱使用权限)以及所需频谱资源等中的一项或多项。
此外，在目标通信系统位于频谱资源管理装置600的管理区域内的情况下，接口单元612还可以将频谱资源管理装置600最终为目标通信系统分配的可用频谱资源的信息发送给目标通信系统。例如，接口单元612可以将可用资源更新单元606更新后的可用频谱资源的信息发送给目标通信系统。
在目标通信系统位于频谱资源管理装置600的管理区域外的情况下，接口单元612可以从目标通信系统所属的频谱资源管理装置接收目标通信系统的频谱利用特性，例如目标通信系统的位置信息、频谱发射模板、传输带宽、载波频率、干扰门限、服务质量要求(指示频谱使用权限)以及所需频谱资源等中的一项或多项。
此外，在目标通信系统位于频谱资源管理装置600的管理区域外的情况下，接口单元612还可以将频谱资源管理装置600最终可以为目标通信系统分配的可用频谱资源的信息发送给目标通信系统所属的频谱资源管理装置。例如，接口单元612可以将可用资源更新单元606更新后的可用频谱资源的信息发送给目标通信系统所属的频谱资源管理装置。
根据本发明的另一实施例，在存在多个频谱管理区域的情况下，频谱资源管理装置600还可以通过接口单元612与其他管理区域对应的频谱资源管理装置协同工作，以使得相对于各个频谱管理区域所确定的目标通信系统的可用频谱资源都能满足目标系统的通信服务质量要求。以下描述频谱资源管理装置600中的接口单元612在该实施例中的各种可能配置。
在目标通信系统位于频谱资源管理装置600的管理区域内时，接口单元612可以从其他频谱资源管理装置接收目标通信系统相对于其他频谱资源管理装置的当前可用频谱资源和通过减少所述其他频谱资源管理装 置所管理的较低权限通信系统的可用频谱资源能够带给目标通信系统的当前可用频谱资源的最大提升量。根据以上描述可知，在所述其他频谱资源管理装置所管理的较低权限通信系统对所述其他频谱资源管理装置所管理的较高权限通信系统不产生干扰的情况下，可以为目标通信系统带来可用频谱资源的最大提升量。
或者，在另一实施例中，接口单元612也可以从其他频谱资源管理装置接收目标通信系统相对于其他频谱资源管理装置的当前可用频谱资源和在该管理区域内的较低权限通信系统对该管理区域内的较高权限通信系统不产生干扰的情况下目标通信系统的最大可用频谱资源(也称为调整后预计可用频谱资源)。如上所述，可以通过将目标通信系统相对于其他频谱资源管理装置的当前可用频谱资源加上通过减少该其他频谱资源管理装置所管理的较低权限通信系统的可用频谱资源能够带给目标通信系统的当前可用频谱资源的最大提升量来获得该最大可用频谱资源。
在目标通信系统位于频谱资源管理装置600的管理区域内时，接口单元612还可以向参与频谱利用调整的其他频谱资源管理装置发送频谱利用调整请求。频谱利用调整请求中可以包括目标通信系统的所需频谱资源的信息。频谱利用调整请求中还可以包括目标通信系统所要求的服务质量信息。
当从其他频谱资源管理装置接收的当前可用频谱资源低于目标通信系统的所需频谱资源，并且从该其他频谱资源管理装置接收的当前可用频谱资源与最大提升量之和(即目标通信系统的最大可用资源或调整后预计可用频谱资源)等于或大于目标通信系统的所需频谱资源时，认为该其他频谱资源管理装置需要参与频谱利用调整。向该其他频谱资源管理装置发送频谱利用调整请求，以使其他频谱资源管理装置调整其管理区域内的较低权限通信系统的可用频谱资源，从而能够提升目标通信系统相对于该其他频谱资源管理装置的可用频谱资源，以满足目标通信系统的通信服务质量要求。
另外，接口单元612还可以向所有其他频谱资源管理装置(包括参与频谱利用调整的其他频谱资源管理装置)发送频谱利用调整请求。频谱利用调整请求中可以包括目标通信系统的所需频谱资源的信息。频谱利用调整请求中还可以包括目标通信系统所要求的服务质量信息。所有其他频谱资源管理装置当接收到频谱利用调整请求时，可以减少其管理区域内的较低权限通信系统的可用频谱资源，使得这些较低权限通信系统在减少后的 可用频谱资源的范围内工作时对目标通信系统产生的干扰不超过目标通信系统的干扰门限，以对目标通信系统进行保护。频谱资源管理装置600本身也将减少其管理区域内的较低权限通信系统的可用频谱资源，使得这些较低权限通信系统在减少后的可用频谱资源的范围内工作时对目标通信系统产生的干扰不超过目标通信系统的干扰门限，以对目标通信系统进行保护。另外，对于如以上确定的需要参与频谱利用调整的其他频谱资源管理装置而言，当在进行了上述对目标通信系统的保护行为后其能够为目标通信系统提供的当前可用频谱资源仍低于目标通信系统的所需频谱资源时，可以再次减少其管理区域内的较低权限通信系统的可用频谱资源，并根据这些较低权限通信系统的当前减少后的可用频谱资源来再次更新目标通信系统的可用频谱资源，使得在目标通信系统在当前更新后的可用频谱资源的范围内工作、并且这些较低权限通信系统在当前减少后的可用频谱资源的范围内工作时，对其管理区域内的较高级通信系统的聚合干扰不超过该较高权限通信系统的干扰门限，并根据需要重复上述操作，直到目标通信系统的当前更新后的可用频谱资源等于或高于目标通信系统的所需频谱资源。
在目标通信系统位于频谱资源管理装置600的管理区域内时，接口单元612还可以从参与频谱利用调整的其他频谱资源管理装置接收目标通信系统的更新后的当前可用频谱资源。
在目标通信系统位于频谱资源管理装置600的管理区域内时，接口单元612还可以从其他频谱资源管理装置接收所述其他资源管理装置所管理的较高权限通信系统和相同权限通信系统对该目标通信系统的相应干扰信息。
在目标通信系统位于频谱资源管理装置600的管理区域内时，接口单元612还可以向参与干扰调整的其他频谱资源管理装置发送干扰调整请求。当从其他频谱资源管理装置接收的当前可用频谱资源与最大提升量之和小于目标通信系统的所需频谱资源时，表明仅通过频谱利用调整并不能满足目标通信系统的所需频谱资源，认为该其他频谱资源管理装置需要参与干扰调整。向该其他频谱资源管理装置发送干扰调整请求，以使该其他频谱资源管理装置调整其管理区域内的相同权限通信系统对所述目标通信系统的干扰。
在另一实施例中，当从任一其他频谱资源管理装置接收的当前可用频谱资源与最大提升量之和小于目标通信系统的所需频谱资源时，频谱资源 管理装置600可以将所有的其他频谱资源管理装置及其自身确定为需要参与干扰调整的频谱资源管理装置，并且可以向所有其他频谱资源管理装置发送干扰调整请求。接收到干扰调整请求的其他频谱资源管理装置可以根据该干扰调整请求来减少该频谱资源管理装置的管理区域内的相同权限通信系统对目标通信系统的干扰。在这种情况下，频谱资源管理装置600也可以减少其管理区域内的相同权限通信系统对目标通信系统的干扰。
接口单元612还可以从参与干扰调整的其他频谱资源管理装置接收所述其他资源管理装置所管理的较高权限通信系统和相同权限通信系统对该目标通信系统的调整后的干扰信息。
在经过干扰调整后，频谱资源管理装置600还可以包括所需资源确定单元(未示出)，用于根据协同工作的各个频谱资源管理装置的所有管理区域内的较高权限通信系统和相同权限通信系统对目标通信系统的干扰以及目标通信系统的服务质量要求来重新计算目标通信系统的所需频谱资源，以获得比目标通信系统的初始所需频谱资源低的所需频谱资源。相应地，可以根据重新计算后的所需频谱资源来确定参与频谱利用调整的频谱资源管理装置。
在本发明的另一实施例中，频谱资源管理装置还可以包括调整对象确定单元，以用于确定参与频谱利用调整的频谱资源管理装置和参与干扰调整的频谱资源管理装置。图7是示出根据本发明另一实施例的频谱资源管理装置的配置示例的框图。如图7所示，频谱资源管理装置700包括可用资源确定单元702、资源利用调整单元704、可用资源更新单元706、接口单元712和调整对象确定单元714。其中，可用资源确定单元702、资源利用调整单元704和可用资源更新单元706和接口单元712的配置分别与图6中所示的频谱资源管理装置600中的可用资源确定单元602、资源利用调整单元604、可用资源更新单元606和接口单元612的配置相同，因此其具体细节在此不再赘述。调整对象确定单元714可以将从中接收的当前可用频谱资源低于目标通信系统的所需频谱资源并且从中接收的当前可用频谱资源与最大提升量之和等于或大于目标通信系统的所需频谱资源的其他频谱资源管理装置确定为参与频谱利用调整的频谱资源管理装置。调整对象确定单元714还可以将从中接收的当前可用频谱资源与最大提升量之和小于目标通信系统的所需频谱资源的其他频谱资源管理装置确定为参与干扰调整的频谱资源管理装置。或者，在从任一其他频谱资 源管理装置接收的当前可用频谱资源与最大提升量之和小于目标通信系统的所需频谱资源的情况下，调整对象确定单元714还可以将所有频谱资源管理装置(包括所有其他频谱资源管理装置及其自身)确定为参与干扰调整的频谱资源管理装置。
与上述的目标通信系统位于频谱资源管理装置600的管理区域的情况相对应，在目标通信系统位于频谱资源管理装置600的管理区域以外的情况下，接口单元612除了可以接收其他频谱资源管理装置所管理的目标通信系统的频谱利用特性，例如目标通信系统的位置信息、频谱发射模板、传输带宽、载波频率、干扰门限、服务质量要求以及所需频谱资源等中的一项或多项之外，还可以将目标通信系统的当前可用频谱资源和通过减少频谱资源管理装置600的管理区域内的较低权限通信系统的可用频谱资源能够带给目标通信系统的当前可用频谱资源的最大提升量发送到所述其他频谱资源管理装置。例如，当前可用频谱资源可以是由频谱资源管理装置600中的可用资源确定单元602确定的可用频谱资源。可用资源确定单元602也可以用于确定当前可用频谱资源的最大提升量。根据以上描述可知，在频谱资源管理装置600所管理的较低权限通信系统对较高权限通信系统不产生干扰的情况下，可以为目标通信系统带来该可用频谱资源的最大提升量。
或者，在另一实施例中，接口单元612还可以向所述其他频谱资源管理装置发送目标通信系统相对于该其他频谱资源管理装置的当前可用频谱资源和在频谱资源管理装置600的管理区域内的较低权限通信系统对该管理区域内的较高权限通信系统不产生干扰的情况下目标通信系统的最大可用频谱资源(也称为调整后预计可用频谱资源)。如上所述，可以通过将目标通信系统相对于其他频谱资源管理装置的当前可用频谱资源加上通过减少该管理区域内的较低权限通信系统的可用频谱资源能够带给目标通信系统的当前可用频谱资源的最大提升量来获得该最大可用频谱资源。
在目标通信系统位于频谱资源管理装置600的管理区域以外的情况下，接口单元612还可以向其他资源管理装置发送频谱资源管理装置600的管理区域内的较高权限通信系统和相同权限通信系统对该目标通信系统的相应干扰信息。
在目标通信系统位于频谱资源管理装置600的管理区域以外的情况下，接口单元612还可以从其他频谱资源管理装置接收频谱利用调整请 求。相应地，频谱资源管理装置600中的资源利用调整单元604可以根据该频谱利用调整请求来减少该管理区域内的较低权限通信系统的可用频谱资源。频谱资源管理装置600中的可用资源更新单元606可以根据较低权限通信系统的调整后的可用频谱资源来更新目标通信系统的当前可用频谱资源，以使得这些较低权限通信系统在减少后的可用频谱资源的范围内工作时对目标通信系统产生的干扰不超过目标通信系统的干扰门限，以对目标通信系统进行保护。当更新后的目标通信系统的当前可用频谱资源仍低于目标通信系统的所需频谱资源时，频谱资源管理装置600中的可用资源更新单元606可以再次减少频谱资源管理装置600的管理区域内的较低权限通信系统的可用频谱资源，并根据这些较低权限通信系统的当前减少后的可用频谱资源来再次更新目标通信系统的可用频谱资源，使得在目标通信系统在当前更新后的可用频谱资源的范围内工作、并且这些较低权限通信系统在当前减少后的可用频谱资源的范围内工作时，对其管理区域内的较高级通信系统的聚合干扰不超过该较高权限通信系统的干扰门限，并根据需要重复上述操作，直到目标通信系统的当前更新后的可用频谱资源等于或高于目标通信系统的所需频谱资源。
在目标通信系统位于频谱资源管理装置600的管理区域以外的情况下，接口单元612还可以向其他频谱资源管理装置发送目标通信系统的更新后的当前可用频谱资源。
在目标通信系统位于频谱资源管理装置600的管理区域以外的情况下，接口单元612还可以从其他频谱资源管理装置接收干扰调整请求。相应地，频谱资源管理装置600还可以包括干扰调整单元(未示出)，用于根据该干扰调整请求来减少该管理区域内的相同权限通信系统对目标通信系统的干扰。
在目标通信系统位于频谱资源管理装置600的管理区域以外的情况下，接口单元612还可以向其他频谱资源管理装置发送该管理区域内的相同权限通信系统对该目标通信系统的调整后的干扰信息。
在本发明的另一实施例中，在目标通信系统位于频谱资源管理装置600的管理区域以外的情况下，接口单元612还可以将频谱资源管理装置600最终可以为目标通信系统分配的可用频谱资源的信息发送给目标通信系统所属的频谱资源管理装置。例如，频谱资源管理装置600可以根据接口单元612从其他频谱资源管理装置接收的目标系统的频谱利用特性中的所需频谱资源信息以及由频谱资源管理装置600的可用资源确定单 元602确定的频谱资源管理装置600能够为目标通信系统所提供的当前可用频谱资源和当前可用频谱资源的最大提升量，对频谱资源管理装置600的管理区域内的频谱资源使用进行频谱利用调整和/或干扰调整，以确定频谱资源管理装置600最终可以为目标通信系统分配的可用频谱资源。
还可以根据设计需要为接口单元612提供更多配置，这里不再赘述。
以下参考图8来描述根据本发明实施例的频谱资源管理方法。图8是示出根据本发明实施例的频谱资源管理方法的示意性流程图。
如图8所述，该方法开始于步骤800。在步骤800之后，该方法前进到步骤802。
步骤802为可用资源确定步骤。在步骤802中，可以确定目标通信系统的可用频谱资源，使得在目标通信系统在该可用频谱资源的范围内工作、并且当前频谱管理区域内的较低权限通信系统在较低权限通信系统的可用频谱资源的范围内工作时，目标通信系统和较低权限通信系统对当前频谱管理区域内的较高权限通信系统产生的聚合干扰不超过较高权限通信系统的干扰门限。这里，较高权限通信系统具有比目标通信系统高的频谱使用权限，较低权限通信系统具有比目标通信系统低的频谱使用权限。当前频谱管理区域是实施该方法的区域，通过该方法对当前频谱管理区域内的多级频谱使用权限级别的通信系统进行频谱资源管理。
在步骤802之后，该方法前进到步骤804。
步骤804为资源利用调整步骤。在步骤804中，可以减少当前频谱管理区域内的较低权限通信系统的可用频谱资源，使得较低权限通信系统在减少后的可用频谱资源的范围内工作时对目标通信系统产生的干扰不超过目标通信系统的干扰门限。
在步骤804之后，该方法前进到步骤806。
步骤806为可用资源更新步骤。在步骤806中，可以根据较低权限通信系统的减少后的可用频谱资源来更新目标通信系统的可用频谱资源，使得在目标通信系统在更新后的可用频谱资源的范围内工作、并且较低权限通信系统在减少后的可用频谱资源的范围内工作时，对当前频谱管理区域内的较高权限通信系统产生的聚合干扰不超过较高权限通信系统的干扰门限。
然后，该方法在步骤808结束。
图8所示的频谱资源管理方法是与图1所示的频谱资源管理装置对应的方法，其具体细节在此不再赘述。
以下结合图9来描述根据本发明另一实施例的频谱资源管理装置的配置。图9是示出根据本发明另一实施例的频谱资源管理装置的配置示例的框图。
如图9所示，频谱资源管理装置900包括接口单元912和调整对象确定单元914。
接口单元912可以接收关于目标通信系统请求利用较高权限通信系统的频谱资源的频谱利用请求。接口单元912还可以将该目标通信系统的频谱利用特性提供至其它频谱资源管理装置。接口单元912还可以从所述其它频谱资源管理装置接收该目标通信系统对所述其它频谱管理系统的相应可用频谱资源信息。
调整对象确定单元914可以被配置为基于接口单元912所接收的可用频谱资源信息确定参与频谱利用调整的其它频谱资源管理装置。
接口单元912还可以被配置为向参与频谱利用调整的其它频谱资源管理装置发送频谱利用调整请求。
在一个实施例中，频谱利用调整请求可以包括目标通信系统所需的频谱资源信息。
在一个实施例中，接口单元912还可以从其它频谱资源管理装置接收所述其它频谱资源管理装置所管理的较高权限通信系统和相同权限通信系统对目标通信系统的干扰信息。
图10是示出根据本发明另一实施例的频谱资源管理装置的配置示例的框图。如图10所示，频谱资源管理装置1000包括接口单元1012、调整对象确定单元1014和所需资源确定单元1008。其中，接口单元1012和调整对象确定单元1014的配置分别与图9中所示的频谱资源管理装置900中的接口单元912和调整对象确定单元1014的配置相同，因此其具体细节在此不再赘述。下面详细描述频谱资源管理装置1000中的所需资源确定单元1008。
所需资源确定单元1008可以基于目标通信系统所要求的服务质量信息以及接口单元1012接收的干扰信息来确定目标通信系统所需的频谱资源信息。其中，服务质量信息可以包括在接口单元1012所接收的频谱利用请求中。
在一个实施例中，接口单元1012所接收的相应可用频谱资源信息可以包括当前可用频谱资源以及调整后预计可用频谱资源信息。在另一个实施例中，接口单元1012所接收的相应可用频谱资源信息也可以包括目标通信系统相对于其他频谱资源管理装置的当前可用频谱资源以及通过减少该其他频谱资源管理装置所管理的较低权限通信系统的可用频谱资源能够带给目标通信系统的当前可用频谱资源的提升量。相应地，可以由接口单元1012或频谱资源管理装置1000中的任何其他部件根据该相应可用频谱资源信息来计算目标通信系统相对于其他频谱资源管理装置的调整后预计可用频谱资源信息。具体而言，调整后预计可用频谱资源信息可以为当前可用频谱资源与提升量之和。
在一个实施例中，当相对于其它频谱管理系统的当前可用频谱资源低于目标通信系统所需的频谱资源而调整后预计可用频谱资源相当于或高于目标通信系统所需的频谱资源时，调整对象确定单元1014可以将该其它频谱管理系统确定为参与频谱利用调整的其它频谱资源管理装置。
在一个实施例中，当相对于其它频谱管理系统的当前可用频谱资源高于目标通信系统所需的频谱资源时，调整对象确定单元1014不将该其它频谱管理系统确定为参与频谱利用调整的其它频谱资源管理装置。
在一个实施例中，当多个频谱资源管理装置协同工作时，使所有频谱资源管理装置所管理的较低权限通信系统对目标通信系统进行保护，也就是说，减少所有频谱资源管理装置所管理的较低权限通信系统的可用频谱资源，使得所述较低权限通信系统在减少后的可用频谱资源的范围内工作时对目标通信系统产生的干扰不超过目标通信系统的干扰门限。而仅对参与频谱利用调整的频谱资源管理装置所管理的较低权限通信系统进行进一步的频谱利用调整，也就是说，在目标通信系统的通过上述保护而更新后的可用频谱资源低于目标通信系统的所需频谱资源的情况下，再次减少参与频谱利用调整的频谱资源管理装置所管理的较低权限通信系统的可用频谱资源。
在一个实施例中，当相对于其它频谱管理系统的当前可用频谱资源低于目标通信系统所需的频谱资源而调整后预计可用频谱资源也低于目标通信系统所需的频谱资源时，调整对象确定单元1014可以确定需要对与该目标通信系统同级别的通信系统进行干扰调整。
继续返回来参考图9，在一个实施例中，调整对象确定单元9014可以将所接收的相应可用频谱资源信息与目标通信系统所需的频谱资源相 比较，并根据比较结果确定参与频谱利用调整的频谱资源管理装置。
在一个实施例中，该频谱利用调整请求可以包括指示参与频谱利用调整的其它频谱资源管理装置对其管理的较低权限通信系统进行频谱利用调整的信息。
在一个实施例中，接口单元9012还可以从参与频谱利用调整的其它频谱资源管理装置接收更新的可用频谱资源信息，并根据更新的可用频谱资源信息确定目标通信系统的可用频谱资源。
下面参考图11来描述根据本发明另一实施例的频谱资源管理方法。图11是示出根据本发明另一实施例的频谱资源管理方法的示意性流程图。
如图11所示，该方法开始于步骤1100。在步骤1100之后，该方法前进到步骤1102。
在步骤1102中，可以接收关于目标通信系统请求利用较高权限通信系统的频谱资源的频谱利用请求。
在步骤1102之后，该方法前进到步骤1104。
在步骤1104中，可以将该目标通信系统的频谱利用特性提供至其它频谱资源管理装置。
在步骤1104之后，该方法前进到步骤1106。
在步骤1106中，可以从其它频谱资源管理装置接收目标通信系统相对于所述其它频谱管理系统的相应可用频谱资源信息。
在步骤1106之后，该方法前进到步骤1108。
在步骤1108中，可以基于所接收的可用频谱资源信息确定参与频谱利用调整的其它频谱资源管理装置。
在步骤1108之后，该方法前进到步骤1110。
在步骤1110中，可以向参与频谱利用调整的其它频谱资源管理装置发送频谱利用调整请求。
然后，该方法在步骤1112结束。
图11所示的频谱资源管理方法是与图9所示的频谱资源管理装置对应的方法，其具体细节在此不再赘述。
下面结合图12来描述根据本发明另一实施例的频谱资源管理装置。 图12示出根据本发明另一实施例的频谱资源管理装置的配置示例的框图。
如图12所示，频谱资源管理装置1200包括接口单元1212和可用资源确定单元1202。
接口单元1212可以接收其它频谱资源管理装置所管理的目标通信系统的频谱利用特性。
可用资源确定单元1202可以基于该频谱利用特性、以及该频谱资源管理装置1200所管理的较低权限通信系统的频谱利用情况，确定目标通信系统的当前可用频谱资源以及调整后预计可用频谱资源。其中，可用资源确定单元1202可以预计减少较低权限通信系统的频谱利用能够给目标通信系统带来的可用频谱资源的提升量，以确定调整后预计可用频谱资源。
接口单元1212还可以将当前可用频谱资源以及调整后预计可用频谱资源发送至该其它频谱资源管理装置。
在另一实施例中，接口单元1212也可以将当前可用频谱资源以及预计减少较低权限通信系统的频谱利用能够给目标通信系统带来的可用频谱资源的提升量发送至该其它频谱资源管理装置。相应地，可以由其他频谱资源管理装置根据当前可用频谱资源和提升量来确定调整后预计可用频谱资源。
以下参考图13来描述根据本发明另一实施例的频谱资源管理方法。图13是示出根据本发明另一实施例的频谱资源管理方法的示意性流程图。
如图13所示，该方法开始与步骤1300。在步骤1300之后，该方法前进到步骤1302。
在步骤1302中，可以接收其它频谱资源管理装置所管理的目标通信系统的频谱利用特性。
在步骤1302之后，该方法前进到步骤1304。
在步骤1304中，可以基于所接收的频谱利用特性、以及当前频谱管理区域中的较低权限通信系统的频谱利用情况，确定目标通信系统的当前可用频谱资源以及调整后预计可用频谱资源。
其中，可以通过预计减少所述较低权限通信系统的频谱利用能够给目 标通信系统带来的可用频谱资源的提升量，来确定调整后预计可用频谱资源。
其中，当前频谱管理区域是实施该方法的区域，通过该方法对当前频谱管理区域内的多级频谱使用权限级别的通信系统进行频谱资源管理。
在步骤1304之后，该方法前进到步骤1306。
在步骤1306中，可以将当前可用频谱资源以及调整后预计可用频谱资源发送至该其它频谱资源管理装置。
然后，该方法在步骤1308结束。
图13所示的频谱资源管理方法是与图12所示的频谱资源管理装置对应的方法，其具体细节在此不再赘述。
图14是示出根据本发明实施例的协同工作的多个频谱资源管理装置的示例框图。在图14中，GLDB A和GLDB B是根据本发明实施例的频谱资源管理装置的例子，CRS(认知无线电系统，Cognitive Radio System)A和CRS B是根据本发明实施例的次系统的例子。如图14所示，次系统(例如CRS A或CRS B)向GLDB(例如GLDB A或GLDB B)提供相应信息并从GLDB获得可用频谱资源信息。GLDB(例如GLDB A或GLDB B)与其他GLDB(例如GLDB B或GLDB A)交互并确定次系统的可用频谱资源。
图15是示出根据本发明实施例的频谱资源管理方法的应用示例的示意性时序图。在图15所示的示例中，N个区域中的N个频谱资源管理装置A1至AN协同工作，N为大于2的正整数，每个频谱资源管理装置为根据本发明实施例的频谱资源管理装置。为简洁起见，在图15中仅示出区域1的频谱资源管理装置A1、区域K的频谱资源管理装置AK和区域N的频谱资源管理装置AN，其中K是大于1小于N的正整数。
如图15所示，接收到目标第二级系统(目标通信系统)的频谱利用请求后，频谱资源管理装置A1与其他频谱资源管理装置AK和AN通信，向其他频谱资源管理装置AK和AN发送目标第二级系统的频谱利用特性信息，例如目标第二级系统的干扰门限、所需频谱资源和/或位置信息等。每个其他频谱资源管理装置AK和AN在收到目标第二级系统的频谱利用特性信息后，检测该其他频谱资源管理装置的管理区域内的第三级系统(较低权限通信系统)和目标第二级系统对该其他频谱资源管理装置的管理区域内的第一级系统(较高权限通信系统)的聚合干扰(优选地确定其 管理区域内的第二级系统(相同权限通信系统)和第三级系统与目标第二级系统对第一级系统的聚合干扰)，并确定目标通信系统的当前可用频谱资源；确定在频谱使用受限区域去除来自第三级系统的干扰后所带来的可用频谱资源的提升量；以及检查该其他频谱资源管理装置的管理区域内的现有第一级系统、第二级系统对目标第二级系统的干扰。然后，每个其他频谱资源管理装置AK和AN将所确定的目标第二级系统的当前可用频谱资源和提升量发送给频谱资源管理装置A1。在一个优选实施例中，每个其他频谱资源管理装置AK和AN还可以将所确定的对目标第二级系统的干扰发送给频谱资源管理装置A1。频谱资源管理装置A1根据其自身所确定的目标第二级系统的可用频谱资源和提升量以及从每个其他频谱资源管理装置接收到的当前可用频谱资源和提升量来确定需要进行频谱利用调整的频谱资源管理装置(例如，确定频谱资源管理装置A1和AK需要参加频谱利用调整)，并且在仅通过频谱利用调整无法满足目标第二级系统的所需频谱资源的情况下，协调各个频谱资源管理装置进行干扰调整以改善目标第二级系统的干扰状况。然后，频谱资源管理装置A1可以将重新计算的目标第二级系统的所需频谱资源和频谱利用调整请求(二者可以作为独立的消息，或者所需频谱资源也可以包含在频谱资源调整请求中)发送到所有的其他频谱资源管理装置AK和AN。所有的其他频谱资源管理装置AK和AN调节其所管理的第三级系统的频谱资源，以保护目标第二级系统。频谱资源管理装置A1自身也调节其所管理的第三级系统的频谱资源，以保护目标第二级系统。然后，所选取的参与频谱利用调整的频谱资源管理装置A1和AK为了提升目标第二级系统的可用频谱资源，继续对其所管理的第三级系统进行频谱利用调整，直到满足目标第二级系统的所需频谱资源需求。然后，每个其他频谱资源管理装置AK和AN向频谱资源管理装置A1发送频谱资源确认消息，以将所确定的最终能够为目标第二级系统提供的可用频谱资源告知频谱资源管理装置A1。由此，完成多个频谱资源管理装置A1、AK和AN协同进行的频谱资源管理。关于图15中的各个步骤的具体实现细节，可以参考以上对根据本发明实施例的装置和方法的描述，这里不再重复。
图16是示出根据本发明实施例的频谱资源管理方法的应用示例的示意性流程图。在图16的示例中，为以第二级系统作为目标通信系统的示例。如图16所示，方法自步骤1600开始。然后，在步骤1602中，根据现有干扰状况计算目标第二级系统的所需频谱资源。在仅考虑一个管理区域的情况下，现有干扰状况可以是该管理区域内的较高权限通信系统(例 如第一级系统)和相同权限通信系统(例如第二级系统)对目标第二级系统的干扰状况。在考虑多个管理区域的情况下，现有干扰状况可以是每个管理区域内的较高权限通信系统和相同权限通信系统对目标第二级系统的干扰状况。然后，在步骤1604中，排除所能为目标第二级系统提供的当前可用频谱资源高于目标第二级系统的所需频谱资源的管理区域，这些区域无需进行频谱利用调整。对于余下管理区域，在步骤1606中继续判断如果调整当前可用频谱资源是否可以满足目标第二级系统的要求(所需频谱资源)。如上所述，对于目标第二级系统的当前可用频谱资源和通过减少其中的较低权限通信系统的可用频谱资源能够带给目标第二级系统的当前可用频谱资源的最大提升量之和低于目标第二级系统的所需频谱资源的管理区域，无法仅通过频谱利用调整来满足目标第二级系统的频谱资源需求。在步骤1606中的判断结果为否的情况下，在步骤1608中，判断现有干扰状况是否可以通过调节进行改善。如果是，则在步骤1610中，调整目标第二级系统所受的干扰状况。例如，可以调整所有频谱资源管理区域内的第二级系统对目标第二级系统的干扰。然后，再次进行到步骤1602，根据调整后的现有干扰状况计算目标第二级系统的所需频谱资源，并继续进行步骤1604及后续操作。当在步骤1608中判断判断现有干扰状况不可以通过调节进行改善时，表明无法为目标第二级系统提供所需频谱资源，方法进行到步骤1618，将无法为目标第二级系统提供所需频谱资源这一结果反馈至目标第二级系统。
继续参考图16，如果在步骤1606中判断如果调整当前可用频谱资源可以满足目标第二级系统的要求，则方法进行到步骤1612。在步骤1612中，去除所有管理区域内的第三级系统对目标第二级系统的干扰，以对目标第二级系统进行保护。然后，在步骤1614中，判断是否需要提升目标第二级系统的当前可用频谱资源以满足目标第二级系统的所需频谱资源。如果在步骤1614中判断结果为否，则表明各个管理区域为目标第二级系统提供的当前可用频谱资源均已满足目标第二级系统的所需频谱资源，因此方法进行到步骤1618，将结果反馈至目标第二级系统。另一方面，如果在步骤1614中判断结果为是，表明有管理区域所提供的当前可用频谱资源不满足所需频谱资源，则在步骤1616中继续调整剩余的第三级系统的可用频谱资源，直到满足目标第二级系统的所需频谱资源，直到目标第二级系统的当前可用频谱资源大于或等于所需频谱资源为止。然后在步骤1618中将结果反馈至目标第二级系统。
在步骤1618之后，方法在步骤1620结束。
关于图16中的各个步骤的具体实现细节，可以参考以上对根据本发明实施例的方法的描述，这里不再重复。
