Description

频谱资源重配置的触发方法、装置及电信设备 技术领域
本发明涉及通信领域，具体而言，涉及一种频谱资源重配置的触发方法、装置及电信设备。
背景技术
随着无线电技术的不断进步，各种各样的无线电业务大量涌现，而无线电业务所依托的频谱资源是有限的，面对人们对带宽需求的不断增加，频谱资源表现出极为紧张的局面；而另一方面在传统的固定频谱分配模式下，频谱资源的利用率却不高。
从某种意义上讲，是这种固定分配给授权系统的频谱分配制度造成了频谱资源极为紧张的局面。而认知无线电技术就打破了传统意义上的频谱固定分配制度，将频谱在系统间动态分配，提高了频谱的利用效率。
典型的，如随着人们日常通信需求的不断提高，已经不满足于简单的语音数据通信，视频流媒体业务在人们通信生活中的比重不断增加，这要求更大的带宽作为支撑，国际移动电话(International Mobile Telecom，简称为IMT)系统显现出前所未有的频谱紧张局面，而对于广播电视系统来讲，频谱资源在很大程度上存在着可利用的空间，如某些广播电视系统频谱在某些地区并未被使用；某些广播电视系统频谱在某地区虽有覆盖，但某些时刻没有被使用，整体利用率偏低。而固定的频谱分配方式使得上述未被使用的频谱资源无法重新利用，例如无法为IMT系统所用。通过认知无线电技术IMT系统通过对广播电视系统信息的获取，伺机的占用广电系统在空间和时间上未使用的频谱资源(TV White Space，简称为TVWS)，从而提高广播电视系统频谱的利用率，改善了IMT系统频谱紧张的局面。
这种次级系统伺机占用主系统频谱资源的频谱使用方式，必须保证对主用户有效地保护，即次级系统使用主系统频谱资源时，不能对主系统用户造成有害干扰，这是认知无线电技术能够实现的前提条件。为了达到这样的目的，首先，次级系统的使用频谱及发射参数将受到主系统保护要求的限制，在最初确定这些参数时需要进行准确的决策；其次，次级系统需要及时获知主用户的出现，以便在发现次级系统所占用频谱资源上的主用户重新出现时，及时退出所述频谱资源，避免对主用户的干扰。
上述过程中，从发现主系统重新出现，到重配置管理节点完成重配置决策，再到下发重配命令执行频谱重配置的这段处理时间内，出于主系统保护的角度考虑，次级系统需要断开在空闲频谱上的通信，这会极大的影响次级系统的性能，及业务的连续性。另一方面，由于次级系统自身原因而触发的频谱资源重配置，相关技术中的机制是网络满足了相应的触发条件(如负载过载、干扰过大通信质量不能满足系统要求等)再进行空闲频谱资源的配置申请，是一种事后处理的方式，在这个频谱重配置决策的过程中，次级系统仍然处于问题状态，也对次级系统的性能造成了影响。

下面结合一个实例，对本发明实施例的优选实施方式进行描述。
重配置管理节点指负责次级系统频谱资源重配置管理的功能实体，可以包括以下功能实体中的任一项：频谱协调器(Spectrum Controller，简称为SC)、中心控制节点(Central Control Point，简称为CCP)、重配管理模块(Reconfiguration Management module)、重配功能模块(Reconfiguration Function module)、重配实体(Reconfiguration Entity)、演进的定位实体、演进的定位功能、共存功能。
典型的主系统空闲频谱资源，例如TVWS频谱，包括470MHz-790MHz范围内主系统未使用的频谱资源。在本发明实施例中，以TVWS频谱为例进行描述。主系统保护管理节点以组位置数据库(Geo-Location DataBase，简称为GLDB)为例，次级系统间干扰共存的重配置管理节点以SC为例。TVWS频段CR技术的架构如图3所示。
GLDB负责主系统保护，为次级用户设备或次级系统管理节点提供主系统频谱使用情况，避免主系统受到次级系统的干扰。优选地，为次级用户设备提供其所在位置上的空闲频谱资源，并根据主系统保护准则，计算次级系统用户设备所允许的最大发射功率。
SC为次级系统频谱资源重配置管理节点，负责各次级用户设备间的共存管理，优先级管理，及测量管理。
BS为次级用户设备，其可代表LTE、3G系统、2G系统等蜂窝网系统下的基站，或者WLAN，WRAN，Wimax等IEEE802系统下的接入点。
下面结合图3所示的架构对本发明实施例的优选实施方式进行描述。
优选实施方式一
在该优选实施方式中，SC基于负载统计信息，为BS1做频谱资源重配置决策的实施例。
图4是根据本发明实施例优选实施方式一的频谱资源重配置的触发方法的流程图，如图4所示，包括步骤S402至步骤S410。
步骤S402，SC获取并存储BS1上报的负载统计信息。
在该优选实施方式中，BS1可以周期上报当前网络负载信息，或者负载值上升到预配置门限时上报网络负载信息。
优选地，可以依据网络的容量设定预配置门限，例如设定预配置门限为负载量达到最大容量的90％。
通过BS1对负载统计信息的上报，SC可以掌握负载随时间的变化规律，例如，得出BS1下属小区Cell1，工作日(周一到周五)的中午12点到14点，负载接近满载甚至过载，需要触发空闲频谱资源的配置，以满足小区的负载需求。
步骤S404，根据上述负载统计规律，SC设定定时器，在负载高峰来临之前，触发空闲频谱资源配置过程。
例如，定时器可以设定为负载高峰前10分钟，例如11点50分，触发频谱资源配置。
步骤S406，根据空闲频谱资源申请消息，SC访问GLDB获取此时刻BS1所在位置上的主系统空闲频谱资源信息。
在该优选实施方式中，SC可以发送BS1的位置信息、天线参数信息给GLDB。GLDB可以查找存储的对应位置上的主用户频谱资源使用情况，根据频谱资源使用情况确定可用频率资源，根据BS1的天线参数及各主用户保护准则计算出可用频谱资源上的最大允许发射功率，将确定的上述信息反馈给SC。
例如，GLDB发现存在f1、f2、f3、f4＝710MHz四段可用频谱资源，且根据BS1的天线参数，及各主用户保护准则计算得出各频谱资源上的最大允许发射功率分别为：40dBm，50dBm，40dBm，30dBm。GLDB将上述信息反馈给SC。可用频谱资源如表1所示。
表1 可用频谱资源列表
Figure PCTCN2014089351-appb-000001
步骤S408，SC进行频谱资源重配置决策。
在该优选实施方式中，SC针对表1中所获取到的空闲频谱资源，考虑SC下属其他BS的空闲频谱使用情况，排除BS间彼此干扰的空闲频谱资源，或者对所述BS1在上述空闲频谱资源中的最大允许发射功率进行进一步限制，使BS1在空闲频谱资源 上的通信，不会对其他次级用户设备造成干扰；经过如下BS间共存管理后，BS1的空闲频谱资源及发射功率限制如表2所示。
表2 空闲频谱资源及发射功率限制列表
Figure PCTCN2014089351-appb-000002
例如，f1由于其他BS的占用，BS1无法使用，删除f1；由于邻近其他BS也使用空闲频谱f2，通过干扰计算，BS1的最大允许发射功率降低为10dBm。
将上述频谱资源配置决策结果形成BS1能识别的消息。
步骤S410，SC将频谱资源配置决策结果(如表2所示)发送给BS1。
优选实施方式二
在该优选实施方式中，SC基于干扰统计信息，为BS1做频谱资源重配置决策的实施例。
图5是根据本发明实施例优选实施方式二的频谱资源重配置的触发方法的流程图，如图5所示，包括步骤S502至步骤S510。
步骤S502，SC获取并存储BS1上报的通信性能统计信息。
在该优选实施方式中，BS1可以周期上报当前网络干扰统计信息，或者干扰升高到预设置门限时上报网络干扰统计信息。
优选地，预配置门限可以依据网络的通信性能要求进行设定，即由于干扰上升造成次级系统网络性能下降，通信性能对应一定的干扰等级，根据系统要求，性能低到一定程度所对应的干扰值作为预配置门限。例如，设定预配置门限为掉话率达到2％时所对应的干扰等级。通过BS1对干扰统计信息的上报，SC掌握了干扰随时间的变化规律，例如，得出BS1下属小区Cell1，工作日(周一到周五)的中午12点到14点，干扰等级高于预配置门限，通信性能不能达到运营商要求，需要触发空闲频谱资源的重新配置，以满足小区的通信性能需求。
步骤S504，根据上述干扰统计规律，SC设定定时器，在通信性能恶化来临之前，触发空闲频谱资源配置过程。
例如，定时器可以设定为通信性能恶化前10分钟，例如11点50分，触发频谱资源配置。
步骤S506，SC根据空闲频谱资源申请消息，访问GLDB获取此时刻BS1所在位置上的主系统空闲频谱资源信息。
在该优选实施方式中，SC可以发送BS的位置信息、天线参数信息给GLDB。GLDB查找存储的该位置上的主用户频谱资源使用情况，发现存在f1、f2、f3、f4＝710MHz四段可用频谱资源，且根据BS1的天线参数，及各主用户保护准则计算得出各频谱资源上的最大允许发射功率分别为：40dBm，30dBm，40dBm，30dBm。GLDB将上述信息反馈给SC。如下面空闲频谱资源如表3所示。
表3 空闲频谱资源列表
Figure PCTCN2014089351-appb-000003
步骤S508，SC进行频谱资源重配置决策。
SC针对表3中所获取到的空闲频谱资源，考虑SC下属其他BS的空闲频谱使用情况，排除BS间彼此干扰的空闲频谱，或者对所述BS1在上述空闲频谱中的最大允许发射功率进行进一步限制，使所述BS1在空闲频谱上的通信，不会对其他次级用户设备造成干扰；经过如下BS间共存管理后，BS1的空闲频谱资源及发射功率限制如表4所示。
表4 空闲频谱资源及发射功率限制列表
Figure PCTCN2014089351-appb-000004
例如，f1由于其他BS的占用，BS1无法使用，删除f1；由于邻近其他BS也使用空闲频谱f2，通过干扰计算，BS1的最大允许发射功率降低为10dBm。
将上述频谱资源配置决策结果形成BS1能识别的消息；
步骤S510：SC将频谱资源配置决策结果(表4)发送给BS1。
在该优选实施方式中，次级系统以掉话率作为衡量系统性能的参数，其他参数如空闲频谱小区的吞吐量、误块率、覆盖率、RRC连接建立成功率、E-RAB建立成功率、E-RAB建立阻塞率、误码率，传输速率，切换成功率，这些参数的异常均可以反映通信质量的下降，都可以作为触发空闲频谱资源重配置的原因。
优选实施方式三
在该优选实施方式中，SC根据主系统频谱使用情况信息，分析主系统频谱使用规律，对主系统频谱的未来占空状态进行预测，并依据预测结果为次级系统分配主系统空闲频谱资源。
图6是根据本发明实施例优选实施方式三的频谱资源重配置的触发方法的流程图，如图6所示，包括步骤S602至步骤S608。
步骤S602，SC获取并存储主系统频谱使用情况信息。
在该优选实施方式中，可以按照以下方式获取上述信息：GLDB可以周期发送当前主系统频谱使用情况信息给SC；或者，当主系统频谱使用情况有变化时向SC发送主系统频谱使用变化信息；或者SC周期访问GLDB，读取主系统频谱使用情况信息，或者，当SC下属BS1申请空闲频谱资源时，SC访问GLDB获取主系统频谱使用情况信息。
在该优选实施方式中，GLDB周期的发送主系统频谱使用情况信息，SC根据该信息更新存储主系统频谱信息。
步骤S604，SC根据存储到的主系统频谱使用情况信息，统计其规律，预测空闲频谱状态。
优选地，SC可以进行空闲频谱所属主用户重新出现的时间预测，采用根据业务特性和调度算法分别对主、次系统的信道状态进行建模的方法进行预测。具体预测方法参见相关技术，本发明实施例对此不再赘述。得到预测结果为，信道f1在T1时刻所述主用户将重新出现，因此占用f1资源的BS1将进行频谱重配置。
步骤S606，T1时刻到达前，SC触发对BS1的频谱资源重配置。
访问GLDB获取BS1所在位置上的可用信道列表，及保护要求，如表5所示。
表5 BS1所在位置上可用信道列表
位置 频率MHz 带宽MHz 最大允许
发射功率
L1 f1＝530 8 40dBm
L1 f2＝560 8 30dBm
L1 f3＝480 8 40dBm
L1 f4＝710 8 30dBm
其中包含空闲频谱资源f1，但根据此前的预测，f1的主用户即将回归，因此，为BS1反馈除f1频谱外的其他空闲频谱资源，及相应的最大允许发射功率要求。
将上述频谱资源配置决策结果(如表6所示)形成BS1能识别的消息。
表6 BS1所在位置上除f1频谱外的其他空闲频谱资源列表
Figure PCTCN2014089351-appb-000005
步骤S608，SC将频谱资源配置决策结果发送给BS1。
上述步骤S604中为空闲频谱所属主用户重新出现时间的预测，类似的空闲频谱状态预测还包括：空闲频谱所属主用户重新出现概率的预测，主系统频谱占空状态转换概率预测，主系统频谱占空状态转换时间预测，预测方法均可参见相关技术，本发明实施例对此不再赘述。
优选实施方式四
在该优选实施方式中，SC可以依据负载统计信息，及主系统空闲频谱状态的预测，为该次级用户设备做频谱资源重配置决策。
图7是根据本发明实施例优选实施方式四的频谱资源重配置的触发方法的流程图，如图7所示，包括步骤S702至步骤S708。
步骤S702，SC获取并存储BS1上报的负载统计信息，及主系统频谱使用信息。
在该优选实施方式中，BS1可以周期上报当前网络负载信息，或者负载值上升到预设置门限时上报网络负载信息；
预配置门限可以依据网络的容量进行设定，例如设定预配置门限为负载量达到最大容量的90％。通过BS1对负载统计信息的上报，SC掌握了负载随时间的变化规律， 例如，得出BS1下属小区Cell1，工作日(周一到周五)的中午12点到14点，负载接近满载甚至过载，需要触发空闲频谱资源的配置，以满足小区的负载需求。
步骤S704，根据上述负载统计规律，SC设定定时器，在负载高峰来临之前，触发空闲频谱资源配置过程。
例如，定时器可以设定为负载高峰前10分钟，例如11点50分，触发频谱资源配置。
步骤S706，SC进行频谱资源重配置决策；
首先，获取空闲频谱，由之前获取到的主用户频谱使用信息可以得出，BS1所在位置上存在f1、f2、f3三段空闲频谱资源。
其次，预测主系统空闲频谱状态；预测过程，具体的，SC进行空闲频谱状态转换概率预测，采用根据业务特性和调度算法分别对主、次系统的信道状态进行建模的方法进行预测。具体预测方法可以参见相关技术，本发明实施例不再赘述。得到预测结果为，信道f1、f2、f3信道状态转换为占用状态的概率分别为：50％、10％、20％。
因此确定信道状态转换概率较小(即主用户重新出现的概率最低)的f2作为BS1的配置频谱，如表7所示。
表7 作为BS1的配置频谱的信息表
Figure PCTCN2014089351-appb-000006
将上述频谱资源配置决策结果形成BS1能识别的消息。
步骤S708，SC将频谱资源配置决策结果(如表7所示)发送给BS1。
优选实施方式五
在该优选实施方式中，SC基于干扰统计信息，为BS1作发射参数重配置决策。
图8是根据本发明实施例优选实施方式五的频谱资源重配置的触发方法的流程图，如图8所示，包括步骤S802至步骤S810。
步骤S802，SC获取并存储BS1上报的通信性能统计信息。
BS1工作于空闲频谱f3＝480MHz，发射功率为30dBm。周期上报当前网络干扰统计信息，或者干扰升高到预设置门限时上报网络干扰统计信息。
预配置门限可以依据网络的通信性能要求进行设定，即由于干扰上升造成次级系统网络性能下降，通信性能对应一定的干扰等级，根据系统要求，性能低到一定程度所对应的干扰值作为预配置门限。例如设定预配置门限为掉话率达到2％时所对应的干扰等级。通过BS1对干扰统计信息的上报，SC掌握了干扰随时间的变化规律，例如，得出BS1下属小区Cell1，工作日(周一到周五)的中午12点到14点，干扰等级高于预配置门限，通信性能不能达到运营商要求，需要触发空闲频谱资源的重新配置，以满足小区的通信性能需求。
步骤S804，根据上述干扰统计规律，SC设定定时器，在通信性能恶化来临之前，触发空闲频谱资源配置过程。
定时器可以设定为通信性能恶化前10分钟，例如11点50分，触发频谱资源配置。
步骤S806，根据空闲频谱资源申请消息，SC访问GLDB获取此时刻BS1所在位置上的主系统空闲频谱资源信息，及发射参数限制。
访问过程可以是：SC发送BS的位置信息，天线参数信息给GLDB，GLDB查找存储的该位置上的主用户频谱资源使用情况，发现存在f1、f2、f3、f4＝710MHz四段可用频谱资源，且根据BS1的天线参数，及各主用户保护准则计算得出各频谱资源上的最大允许发射功率分别为：40dBm，30dBm，40dBm，30dBm。GLDB将上述信息反馈给SC。空闲频谱资源如表8所示。
表8 空闲频谱资源列表
Figure PCTCN2014089351-appb-000007
步骤S808，SC进行频谱资源重配置决策。
SC针对表8中所获取到的空闲频谱资源，考虑SC下属其他BS的空闲频谱使用情况，排除BS间彼此干扰的空闲频谱，或者对所述BS1在上述空闲频谱中的最大允许发射功率进行进一步限制，使所述BS1在空闲频谱上的通信，不会对其他次级用户 设备造成干扰；经过如下BS间共存管理后，BS1的空闲频谱资源及发射功率限制如表9所示。
表9 空闲频谱资源及发射功率限制表
Figure PCTCN2014089351-appb-000008
例如，f1由于其他BS的占用，BS1无法使用，删除f1；由于邻近其他BS也使用空闲频谱f2，通过干扰计算，BS1的最大允许发射功率降低为10dBm。
BS1正工作于f3，目前通过主用户保护考虑，及次级系统间共存考虑后，BS1在f3上最大允许发射功率30dBm的限制，实际上是BS1在f3上可以增大的发射功率，即BS1在f3上的最大允许发射功率限制为33dBm。SC决策当BS1在f3上的发射功率增大到33dBm后能够满足通信性能需求，因此决定在f3上升高功率。
将上述频谱资源配置决策结果形成BS1能识别的消息。
步骤S810，SC将频谱资源配置决策结果(表9)发送给BS1。
在本优选实施方式中，次级系统以掉话率作为衡量系统性能的参数，其他参数如空闲频谱小区的吞吐量、误块率、覆盖率、RRC连接建立成功率、E-RAB建立成功率、E-RAB建立阻塞率、误码率，传输速率，切换成功率，这些参数的异常均可以反映通信质量的下降，都可以作为触发空闲频谱资源重配置的原因。
从以上的描述中，可以看出，本发明实现了如下技术效果重配置管理节点通过对主次系统网络信息的获取与存储，预测下一时刻的网络状态，基于网络信息的预测结果触发预先频谱资源重配置决策，这样的预先重配置决策可以有效实现主用户保护的同时，也保障了次级系统的服务质量不受影响，减少了由于重配置决策不当而造成的次级系统通信中断的概率。
