图 1为本发明白频谱资源的获取方法实施例一的流程图， 该实施例的流程 具体可以由白频谱资源请求设备实现。 如图 1所示， 本实施例提供的白频谱获 取方法， 白频谱资源请求设备接收白频语设备发送的白频谱资源请求消息。 本 实施例提供的方法可以包括：
步骤 101、 白频谱资源请求设备接收白频谱设备发送的白频谱资源请求消 息。
白频谱资源请求设备基于 PAWS协议或其他现有协议接收白频谱设备发 送的白频谱资源请求消息，该白频谱资源请求消息包含支持白频语设备使用的 白频语频段、 位置信息、 发射功率等。
步骤 102: 白频谱资源请求设备向白频语设备发送白频谱资源响应消息。 白频谱资源请求设备在接收到白频语设备发送的白频谱资源请求消息后， 基于 PAWS协议向白频语数据库请求的、且与白频谱设备的第一白频谱需求信 息对应的白频谱资源信息并向白频谱设备发送白频谱资源响应消息。
本发明实施例提供的白频谱获取方法，白频语设备通过向白频谱资源请求 设备发送白频谱资源请求消息，白频语资源请求设备事先或是接收到白频谱资 源请求消息后从白频语数据库中请求的、且与该白频谱设备的第一白频谱需求 信息对应的白频谱资源信息，并向从属设备发送包含与需求信息对应的白频谱 资源信息，进而利用白频谱资源。上述过程中，白频谱资源请求设备基于 PAWS 协议向白频谱数据库请求白频谱资源信息，白频语设备与白频谱资源请求设备 之间的交互可以通过现有协议建立，使得白频谱设备无需与数据库建立连接来 获取白频谱资源， 不需要定义新的接口支持 PAWS协议。
上述实施例中， 若白频谱资源请求设备近期执行过 PAWS协议向数据查询 白频谱资源，存储有向白频语数据库获取的支持自身的白频谱资源。 因此在接 收到白频语设备发送的白频谱资源请求消息之后，根据白频谱资源请求消息中 的白频谱频段信息判断确定预先从白频谱数据库中获取的白频谱资源中是否 有白频语设备支持的白频语信息，即是否包含与白频语设备的第一白频谱需求 信息对应的白频谱资源，如有， 则将与白频语设备的白频谱需求信息对应的白 频谱资源分配给白频语设备。 例如， 白频谱资源请求设备可以根据具体的策略 将存储的部分或全部的白频谱资源分配给白频语设备，以使得白频语设备从分 配到的白频谱资源中选择使用的白频谱资源； 否则， 向白频语设备发送用于指 示无白频谱资源可用的指示消息。
上述实施例中，当白频谱资源请求设备判断出自身存储的可用白频谱资源 中不包含与白频语设备的白频谱资源需求信息对应的可用白频谱资源时，根据 接收到的白频谱资源请求消息，白频谱资源请求设备向白频语数据库发送第一 资源获取请求消息，该第一资源获取请求消息携带白频语设备的第一白频谱需 求信息。 白频语数据库根据第一资源请求消息， 查询并反馈给白频谱资源请求 设备， 向白频谱资源请求设备发送第一资源获取响应消息， 该第一资源获取响 应消息携带与白频谱设备的第一白频谱需求信息对应的白频谱资源。
本实施例中，白频谱资源请求设备可以根据白频语设备的第一白频谱需求 信息向白频谱数据库发送第一资源获取消息以向查询并获取支持白频谱设备 的白频谱资源。
另外， 白频谱资源请求设备可以定期监测白频谱设备， 或是在网络出现异 常等情况， 例如， 当白频谱资源请求设备监测到白频谱设备目前使用的白频谱 已经到期或根据预先的策略确定需要激活白频语设备时，向白频语设备发送白 频谱资源重配置消息，重配置消息中携带支持白频语设备使用的其他白频谱频 段信息。 白频语设备在接收到白频谱资源重配置消息后， 向白频谱资源请求设 备发送白频谱资源重配置响应消息。白频谱资源请求设备接收白频语设备发送 的白频谱资源请求信息包含白频语设备的第一白频谱需求信息。
本发明上述实施例中，白频谱资源请求设备在确定预先从白频谱数据库中 获取的白频谱资源中是否包含与白频谱设备的第一白频谱需求信息对应的白 频谱资源之前，可以根据自身的策略向发起查询白频谱数据库以获取白频谱资 源。 具体的， 例如， 近期没有执行过 PAWS协议向白频谱数据库获取可用白频 谱资源，则白频谱资源请求设备可以向白频语数据库发送包含白频谱资源请求 设备的第二白频谱需求信息的第二资源获取请求消息，向数据查询并获取支持 自身的可用白频谱资源。白频谱数据库根据第二资源获取请求消息向白频谱资 源请求设备发送第二资源获取响应消息，该第二资源获取响应消息包含与白频 谱资源请求设备的第二白频谱资源需求信息对应的白频谱资源。
本发明上述实施例中， 白频谱资源请求设备基于 PAWS协议向白频语数据 库查询并获取支持自身的可用白频谱资源，是否发起查询白频谱数据库的行为 是由白频谱资源请求设备根据自身的策略决定。当接收到基于现有协议与之建 立连接的白频语设备发送的白频谱资源请求消息后，根据白频谱资源请求消息 中的第一白频谱需求信息判断储存的支持白频谱资源请求设备自身的可用白 频谱资源并分配给白频谱设备。
本发明上述实施例中，白频谱资源请求设备接收白频谱设备发送的白频谱 资源请求消息之前， 白频谱资源请求设备与白频语设备建立连接， 白频语设备 在与白频谱资源请求设备建立的时候将包含白频谱设备的第一白频谱需求信 息的连接请求消息发送给白频谱资源请求设备，向白频谱资源请求设备上报自 己的白频谱能力，使得白频谱资源请求设备在建立连接的同时知晓白频语设备 的白频谱能力， 例如， 白频谱频段信息、 位置信息， 发射功率等， 使得白频谱 根据连接请求消息中的第一白频谱需求信息为白频谱设备分配可用白频谱资 源或者是需要更新白频谱时对白频谱设备使用的白频谱进行更新。
上述实施例中， 白频语设备的第一白频谱需求信息， 包括白频语设备支持 的白频谱频段信息和 /或白频谱数据库给白频谱设备分配资源所需的参数。 例 如： 白频谱频段信息和 /或位置信息等一切可以指示白频谱设备白频谱能力的 白频谱能力信息；第二白频谱需求信息为白频谱资源请求设备支持的白频谱信 息和 /或白频语数据库给白频谱资源请求设备分配资源所需的参数。
上述实施例中， 白频谱资源请求设备与白频语数据库之间基于 PAWS协议 进行通信， 白频语设备与白频谱资源请求设备之间， 例如可以是建立无线资源 控制消息 （Radio Resource Control, 以下简称 RRC消息)通信或者是直径协议 ( diameter协议)通信。
本发明上述实施例中与白频谱资源请求设备连接的白频谱设备可以为多 个， 多个白频谱设备各自向白频谱资源请求设备请求白频谱资源， 分别上报各 自的白频谱能力信息， 例如： 白频谱频段信息、 位置信息、 发射功率等， 白频 谱资源请求设备将这些白频谱能力信息设置为自身的策略，根据该自身的策略 向白频语数据库查询可用的白频语信息并保存，白频谱设备在需要的时候向白 频谱资源请求设备发送请求，白频谱资源请求设备回传携带支持发起请求的白 频语设备的白频谱频段信息。具体的， 白频语设备例如可以是主白频谱设备或 从属白频语设备，主白频语设备可以基于现有协议与白频谱资源请求设备建立 连接以获取白频谱资源，从属白频语设备除了可以基于现有协议与白频谱资源 侵权设备建立连接外，也可以连接在主白频谱设备上，通过主白频谱设备获取 可用白频谱资源。
图 2为本发明白频谱资源的获取方法实施例二的流程图， 该实施例的流程 具体可以由白频语设备实现。 如图 2所示， 本实施例提供的白频谱获取方法， 白频谱设备向白频谱资源请求设备请求白频谱资源。本实施例提供的方法可以 包括：
步骤 201： 向白频谱资源请求设备发送白频谱资源请求消息。
白频语设备向白频谱资源请求设备发送白频谱资源请求消息，该白频谱资 源请求消息可以为包含白频谱设备的第一白频谱需求信息的基于 PAWS或者 基于其他协议发送的消息。
步骤 202: 接收白频谱资源请求设备发送的白频谱资源响应消息。
白频谱资源请求设备在接收到白频谱资源请求消息后，根据该消息向数据 库请求的、且与白频语设备的第一白频谱需求信息对应的白频谱资源信息并反 馈白频谱资源响应消息给白频语设备， 白频谱设备接收白频谱资源响应消息， 该白频谱资源响应消息中包含与白频谱设备的第一白频谱需求信息对应的白 频谱资源信息。
本发明实施例提供的白频谱获取方法，白频语设备通过向白频谱资源请求 设备发送白频谱资源请求消息，白频语资源请求设备事先或是接收到白频谱资 源请求消息后从白频语数据库中请求的、且与该白频谱设备的第一白频谱需求 信息对应的白频谱资源信息，并向从属设备发送包含与需求信息对应的白频谱 资源信息，进而利用白频谱资源。上述过程中，白频谱资源请求设备基于 PAWS 协议向白频谱数据库请求白频谱资源信息，白频语设备与白频谱资源请求设备 之间的交互可以通过现有协议建立，使得白频谱设备无需与白频语数据库建立 连接来获取白频谱资源， 不需要定义新的接口支持 PAWS协议。
上述实施例中，若白频谱资源请求设备判断出没有可用的白频谱资源分配 给白频谱设备， 则向白频谱设备发送用于指示无白谱频谱资源可用的指示消 息， 白频语设备接收该指示消息。
例如，当白频谱资源请求设备确定出预先从白频语数据库中获取的白频谱 资源中不包括白频语设备的第一白频谱需求信息对应的白频谱资源；或是白频 谱资源请求设备在基于白频谱设备的第一白频谱需求信息查询白频谱数据库 后未获取到包括白频语设备的第一白频谱需求信息对应的白频谱资源；或者是 白频谱资源请求设备在基于自身的第二白频谱需求信息查询白频谱数据库获 取到支持白频谱资源请求设备的可用白频谱资源，但该些支持白频谱资源请求 设备的可用白频谱资源不包括白频谱设备的第一白频谱需求信息对应的白频 谱资源等情况的时候，向白频谱设备发送用于指示无白频谱资源可用的指示消 息， 白频谱设备接收该消息。
本发明的上述实施例中，白频谱资源请求设备与白频语设备之间的交互消 息为 RRC消息或者 Diameter消息等， 白频语设备也可以在与白频谱资源请求设 备建立连接的时候将包含第一白频谱需求信息的连接请求建立消息发送给白 频谱资源请求设备，该第一白频谱需求信息为白频语设备支持的白频谱频段信 息和 /或白频谱数据库给白频谱设备分配资源所需的参数， 例如可以为白频谱 频段信息和 /或位置信息、 发射功率等表征白频谱设备白频谱能力的信息， 使 得白频谱资源请求设备根据该需求信息为白频语设备分配白频谱资源或者，在 检测到需要对白频谱设备进行白频谱资源更新的时候或因白频谱资源请求设 备需要白频谱设备来分流业务时主动发起用于激活白频谱设备利用白频谱资 源分流业务时， 向白频语设备发送白频谱资源重配置消息以更新白频谱资源， 白频谱设备接收该白频谱资源重配置消息进行白频谱资源更新并发送白频谱 资源重配置响应消息。
本发明上述实施例中， 白频谱资源请求设备也可以通过代理设备（以下简 称 Proxy )连接到白频语数据库， 白频语数据库只是负责较大区域内 （如一个 国家）白频谱数据的存储工作以及为 Proxy分配频谱资源， 更为具体的白频谱 分配策略的执行和白频谱判决功能由 Proxy来承担。 Proxy可以是由负责某一 个区域的监管机构负责操作和维护，也可以有电信运营商或者一些获得授权的 分公司负责操作和维护， 这些操作与维护实体根据需要为自己所负责的 Proxy 制定不同的白频语分配策略。对于 Database会有艮多的 proxy与其相连，每个 proxy负责 Database覆盖范围内一个子区域的白频谱的分配工作，且不同 proxy 所负责的区域之间允许存在相互重叠的部分。 信道信息： （ 1 ) database 定期向 proxy发送频谱更新消息来更新 proxy中的白 频语数据， 即 push方式； （ 2 ) proxy根据需求主动向 database发送频语数据更 新请求， 即 pull方式。 proxy中存储了其所负责区域内的所有白频语数据信息 (从 Database 中得到）和所负责区域的频谱管理规定信息， 可以申请和获取 白频谱数据库中的所负责区域内的可用频谱信息， 根据 Master所传递的频谱 请求消息中提供的信息结合相应的频谱分配策略进行频谱分配的计算，从而为 Master分配频谱资源。
本发明上述实施例中，白频语设备与白频谱资源请求设备之间可以除基于
PAWS协议或其他现有协议建立连接， 白频谱资源请求设备与白频谱数据库或 Proxy之间基于 PAWS协议建立连接， 使得白频谱设备无需与白频谱数据库建 立连接来获取白频谱资源， 不需要定义新的接口支持 PAWS协议。
本发明上述实施例中与白频谱资源请求设备连接的白频谱设备可以为多 个， 多个白频谱设备各自向白频谱资源请求设备请求白频谱资源， 分别上报各 自的白频谱能力信息， 例如： 白频谱频段信息、 位置信息、 发射功率等， 白频 谱资源请求设备将这些白频谱能力信息设置为自身的策略，根据该自身的策略 向白频语数据库查询可用的白频语信息并保存，白频谱设备在需要的时候向白 频谱资源请求设备发送请求，白频谱资源请求设备回传携带支持发起请求的白 频语设备的白频谱频段信息。具体的， 白频语设备例如可以是主白频谱设备或 从属白频语设备，主白频语设备可以基于现有协议与白频谱资源请求设备建立 连接以获取白频谱资源，从属白频语设备除了可以基于现有协议与白频谱资源 侵权设备建立连接外，也可以连接在主白频谱设备上，通过主白频谱设备获取 可用白频谱资源。 明。
图 3 A为本发明方法应用于 3 GPP中 Hetnet应用场景的第一信令流程图。 第 三代合作伙伴 ( the 3rd Generation Partnership Project以下简称 3GPP ) 中， 中继 站（Relay Node, 以下简称 RN )为白频谱设备， 主要基地台 （ Donor eNodeB , 以下简称 DeNB ) 为白频谱资源请求设备， 白频谱资源请求消息携带在无线资 源控制消息 （ Radio Resource Control , 以下简称 RRC消息）中。 如图 6Α所示， 该实施例的技术方案， 包括：

RN上电接入网络， 与 DeNB建立 RRC连接并进行通信， 使用的无线资源可 以是白频谱资源之外的任何资源。
步骤 302a、 RN判断是否需要使用白频谱资源。
RN根据自己当前的地理位置、 所需带宽等信息， 判断是否需要使用白频 谱资源， 若当前使用的频谱满足自身需要， 则保持当前状态； 否则， 向 DeNB 发起白频谱资源协商流程。
步骤 303a: 发送 RRC消息。

本实施例中， Client与 Server之间基于直径协议（ diameter协议 )进行通信， Server与白频语数据库之间基于 PAWS进行通信。本实施例中， 由于 Server近期 执行过 PAWS协议向白频谱数据库查询并预先保存了支持白频谱资源请求设 备的可用白频谱资源。 因此本实施例中 Server无需与白频"普数据库建立连接查 询支持其使用的白频谱资源， 然而， 在其他实施例中， Server也可以根据接收 到的白频谱请求消息直接向白频语数据库查询并获取 Client支持的可用白频谱 资源， 也可以事先向白频语数据库获取并储存支持 Server的可用白频谱资源列 表。
图 4A为本发明方法应用于 3GPP中 Hetnet应用场景的第二信令流程图。 本 实施例与图 4A实施例的差别之处在于白频谱资源请求消息中还携带有位置信 息，若预先从白频语数据库中获取的白频谱资源中不包含与白频语设备的白频 谱需求信息对应的白频谱资源，则白频谱资源请求设备向白频谱数据库发送第 一资源获取请求消息，该第一资源获取请求消息包含位置信息，根据该位置信 息向白频谱数据库查询以获取该位置信息指示的位置上的可用白频谱资源列 表。 如 4A所示， 该实施例的技术方案， 包括：

步骤 409a: DeNB发送 RRC响应消息。
若有需要的白频谱频段， 则向 RN发送 RRC响应消息， 该响应消息携带获 取到的白频谱频段； 否则， 向 RN发送 RRC失败消息， 指示无可用白频谱频段。
本实施例中， RN与 DeNB之间基于 RRC进行通信， DeNB与白频谱数据库 之间基于 PAWS进行通信， DeNB向白频谱数据库发送包含 RN的白频谱需求信 息的第一资源请求消息并保存，判断该通过第一资源获取请求消息获取到的白 频谱资源中是否包含支持 RN的白频谱频段。
图 4B为本发明方法实施例应用于 IETF场景的第二信令流程图。 互联网工 程任务组（ Internet Engineering Task Force,以下简称 IETF )中，客户端（ Client ) 为白频语设备， 服务器（Server ) 为白频谱资源请求设备， 白频谱资源请求消 息携带在能力交互消息中。 如 4B所示， 该实施例的技术方案， 包括：

Answer ) , 该 Capabilities Exchange Answer中携带支持 Client的白频谱频段。
步骤 406b： Server向白频语数据库发送第一资源获取请求消息。
本步骤中， 若步骤 404b中 Serve判断出第一可用白频谱资源列表中不包含 相应的白频语频段， 则根据步骤 403b中接收到的 Capabilities Exchange request, 向白频语数据库发送第一资源获取请求消息，该第一资源获取请求消息中携带
Client的白频谱需求信息。 具体的， Server与白频 "普数据库通过 PAWS协议建立 连接， Server发起请求消息， 请求与 PAWS建立连接， PAWS响应以建立连接。
407b: 接收白频语数据库发送的第一资源获取响应消息。
Server向白频谱数据库发起查询请求， 基于 Capabilities Exchange request, 查询白频语数据库以获取可用白频谱资源， 如有， 白频语数据库向 Server发送 第一资源获取响应消息， Server保存基于白频谱设备的白频谱资源。 例如， 可 以基于 Capabilities Exchange request中的位置信息查询白频谱数据库中是否有 该位置信息指示的位置可用的白频谱资源列表， 。

图 5为本发明方法应用于 3GPP中 Hetnet应用场景的第三信令流程图。 本实 施例与图 3A、 图 4A实施例类似， 差别之处仅在于， 本实施例中， DeNB在与 RN建立连接的时候就接收 RN发送的白频谱资源请求 RRC消息。 具体的， 本实 施例包括如下步骤：
步骤 501 : RN上电接入网络， 建立连接， 发送 RRC消息， 该 RRC消息至少 包括 RN支持使用的白频谱频段信息。
与图 3A、 图 4A所示不同， 本实施例中， RN上电接入网络的时候， 与 DeNB 建立 RRC连接， 并在建立连接的过程中指示自己的白频谱能力， 即向 DeNB告 知自己支持的白频谱频段。
步骤 503： DeNB判断预先从白频语数据库中获取的白频谱资源中是否包含 支持相应的白频谱频段。
步骤 504: DeNB发送 RRC响应消息。
若有需要的白频谱频段， 则向 RN发送 RRC响应消息， 该响应消息携带获 取到的白频谱频段； 否则， 向 RN发送 RRC失败消息， 指示无可用白频谱频段。
在本发明另一实施例中， 判断预先从白频语数据库中获取的白频谱资源 中是否包含支持白频语设备使用的白频谱频段前，白频谱资源请求设备还可以 向白频谱数据库发起查询流程，查询并获取支持该白频谱设备的第一可用白频 谱资源列表。 具体的， 再请参照图 5, 本实施例还包括：
步骤 502: 根据 DeNB自己的策略查询支持 DeNB的白频谱资源。 具体的， 步骤 502包括：
步骤 5021： DeNB向白频语数据库发送第二资源获取请求消息。
DeNB发起请求消息， 请求与 PAWS建立连接， PAWS响应以建立连接。 步骤 5022: 接收白频谱数据库发送的第二资源获取响应消息。
DeNB向白频谱数据库发起查询请求， 根据自己的策略， 查询白频谱数据 库中是否有支持其自身的可用白频谱资源， 如有， 则获取并保存。
一般来说，第二资源获取请求消息为白频谱资源请求设备根据自己的策略 向白频语数据库请求的支持自身的白频谱资源，从这些支持白频谱资源请求设 备的可用白频谱资源判断是否有支持白频谱设备的白频谱频段；而第一资源获 取请求消息中包含所述白频语设备的第一白频谱需求信息。
在本发明白频谱资源的获取方法的又一实施例中，对于已经使用白频谱资 源的白频语设备， 当需要更新白频谱资源时， 白频谱资源请求设备还可以向白 频谱设备发送白频谱重配置消息，对白频谱设备使用的白频谱进行更新， 具体 的， 请参照图 6。
图 6为本发明方法应用于 3GPP中 Hetnet应用场景的第四信令流程图。 图 6 实施例与图 5实施例的差别之处在于， 当 DeNB检测到 RN使用的白频谱资源需 要更新时， 向 RN发送白频谱重配置消息， 对 RN使用的白频谱资源进行重新配 置。 如图 6所示， 本实施例包括如下步骤：
步骤 601 : RN上电接入网络， 建立连接， 发送 RRC消息， 该 RRC消息至少 包括 RN使用的白频谱频段信息。 步骤 602: 根据 DeNB自己的策略查询支持 DeNB的白频谱资源。 具体的， 步骤 602包括：
步骤 6021： DeNB向白频语数据库发送第二资源获取请求消息。
DeNB发起请求消息， 请求与 PAWS建立连接， PAWS响应以建立连接。 步骤 6022: 接收白频谱数据库发送的第二资源获取响应消息。
步骤 603: DeNB根据 RRC消息中的白频谱频段信息，判断基于第二资源获 取到的白频谱资源中是否包含支持的白频谱频段。
上述步骤 601-步骤 603请参见图 5所示步骤 501-步骤 503 , 此处不再贅述。 步骤 604: 发送 RRC重配置消息， 该 RRC重配置消息携带 RN支持的白频谱 频段。
当 DeNB监测到 RN目前使用的白频谱影响到原始用户的频谱使用时，需要 主动向 RN发起白频谱重配置消息， 以更新 RN使用的白频谱频段， 该重配置消 息携带 RN将要使用的白频谱频段。
步骤 605: RN向 DeNB发送重配置响应消息， 该重配置响应消息携带 RN更 新后的白频谱频段信息， 告知 DeNB哪个白频谱频段已被使用。
在其他实施例中，发送重配置消息也可以在白频谱资源请求设备查询白频 谱数据库，即向白频谱数据库发送第一资源请求消息并接收白频谱数据库反馈 的第一资源获取响应消息， 判断获取到的白频谱资源中是否有支持 RN的白频 谱频段之后， 若 RN近期执行过 PAWS 协议向白频谱数据库查询过可用白频谱 资源， 则可以不再向白频谱数据库查询。
上述实施例中， 白频谱资源请求设备是以 3GPP异构网络中的 DeNB以及基 于 Diameter协议的 Server为例， 白频谱设备是以 RN以及 Client为例来阐述本发 明， DeNB与 RN之间基于 RRC协议建立连接已进行通信， Server与 Client之间基 于 Diameter协议建立连接， DeNB或 Server作为白频谱资源请求设备， 基于 PAWS协议与白频谱数据库或代理设备进行通信以获取白频谱资源， 然本发明 并不以此为限。在其他实施例中， 白频谱资源请求设备及白频语设备例如可以 是微微基站 （以下简称 pico ) 、 豪微微基站 （以下简称 Femto )等移动通信网 络节点。

进一步的，发送模块 15还用于在确定模块 12确定出预先从白频谱数据库中 获取的白频谱资源中不包含与白频谱设备的第一白频谱需求信息对应的白频 谱资源后， 向白频谱设备发送用于指示无白频谱资源可用的指示消息。
上述实施例中，当确定模块 12判断出出预先从所述白频语数据库中获取的 可用白频谱资源中不包含与白频谱设备的第一白频谱资源需求信息对应的可 用白频谱资源时，根据接收到的白频谱资源请求消息，发送模块 15向白频谱数 据库发送第一资源获取请求消息 ,该第一资源获取请求消息携带白频语设备的 第一白频谱需求信息。 白频语数据库根据第一资源请求消息， 查询数据库并反 馈， 向接收模块 11发送第一资源获取响应消息， 该第一资源获取响应消息携带 与白频语设备的第一白频谱需求信息对应的白频谱资源。

白频谱资源请求设备可以定期监测白频语设备，或是在网络出现异常等情 况， 例如， 当到白频语设备目前使用的白频谱已经到期或根据预先的策略确定 需要激活白频语设备时，重配置模块 14向白频语设备发送白频谱资源重配置消 息，该白频谱资源重配置消息中包含与白频语设备的第一白频谱需求信息对应 的白频谱资源。 白频语设备在接收到白频谱资源重配置消息后，发送白频谱资 源重配置响应消息；接收模块 11还用于在重配置模块 14发送白频谱资源重配置 消息后，接收白频语设备发送的白频谱资源请求信息包含白频语设备的第一白 频谱需求信息。
上述实施例中，确定模块 12在确定预先从白频谱数据库中获取的白频谱资 源中是否包含与白频语设备的第一白频谱需求信息对应的白频谱资源之前，可 以根据自身的策略向发起查询白频谱数据库以获取白频谱资源。具体的，例如， 近期没有执行过 PAWS协议向白频谱数据库获取可用白频谱资源， 则发送模块 15可以向白频谱数据库发送包含白频谱资源请求设备的第二白频谱需求信息 的第二资源获取请求消息， 向数据查询并获取支持自身的可用白频谱资源。 白 频谱数据库根据第二资源获取请求消息向白频谱资源请求设备发送第二资源 获取响应消息， 该第二资源获取响应消息包含支持设备的可用白频谱资源， 即 第二资源获取响应消息包含与白频谱资源请求设备的白频谱资源需求信息对 应的白频谱资源。接收模块 11接收白频语设备发送的白频谱资源请求信息包含 白频语设备的第一白频谱需求信息。
本发明上述实施例中，接收模块 11接收白频语设备发送的白频谱资源请求 消息之前， 白频谱资源请求设备与白频谱设备建立连接， 白频谱设备在与白频 谱资源请求设备建立的时候将包含白频谱设备的第一白频谱需求信息的连接 请求消息发送给接收模块 11 , 以向白频谱资源请求设备上报自己的白频谱能 力， 使得白频谱资源请求设备在建立连接的同时知晓白频谱设备的白频谱能 力， 例如， 白频谱频段信息、 位置信息， 发射功率等， 使得白频谱资源请求设 备根据连接请求消息中的第一白频谱需求信息为白频谱设备分配可用白频谱 资源或者是需要更新白频谱时对白频谱设备使用的白频谱进行更新。
上述实施例中， 白频语设备的第一白频谱需求信息， 包括白频谱设备支持 的白频谱频段信息和 /或白频谱数据库给白频谱设备分配资源所需的参数。 例 如： 白频谱频段信息和 /或位置信息等一切可以指示白频谱设备白频谱能力的 白频谱能力信息；第二白频谱需求信息为白频谱资源请求设备支持的白频谱信 息和 /或白频语数据库给白频谱资源请求设备分配资源所需的参数。 本发明实施例提供的白频谱资源请求设备对白频谱资源的获取流程，可以 参见上述白频谱资源获取方法实施例提供的方法， 此处不再详细贅述。
本发明实施例提供的白频谱资源请求设备，接收白频谱设备发送的白频谱 资源请求消息，事先或是接收到白频谱资源请求消息后从白频谱数据库中请求 的、且与该白频语设备的第一白频谱需求信息对应的白频谱资源信息， 并向从 属设备发送包含与需求信息对应的白频谱资源信息， 进而利用白频谱资源。本 发明实施例中， 白频谱资源请求设备基于 PAWS协议向白频语数据库请求白频 谱资源信息，白频语设备与白频谱资源请求设备之间的交互可以通过现有协议 建立，使得白频谱设备无需与白频谱数据库建立连接来获取白频谱资源， 不需 要定义新的接口支持 PAWS协议。
图 10为本发明白频谱资源获取的白频语设备实施例一的结构示意图，如图 10所示， 本实施例的白频谱设备可以包括：

进一步的，若白频谱资源请求设备判断出没有可用的白频谱资源分配给白 频语设备， 则接收模块 22,还用于接收白频谱资源请求设备发送的用于指示无 白频谱资源可用的指示消息。
图 11为本发明白频谱资源获取的白频语设备实施例二的结构示意图，如图
11所示， 本实施例的白频谱设备可以包括：

上述实施例中，发送模块 21还用于向白频谱资源请求设备发送的白频谱资 源请求消息， 携带白频谱设备的第一白频谱需求信息。 具体的， 该第一白频谱 需求信息，可以在白频谱设备判断是否需要使用白频谱后向白频谱资源请求设 备发送，也可以在与白频谱资源请求设备建立连接的时候携带在连接请求消息 中发送， 向白频谱资源请求设备上报自身的白频语能力，使得白频谱资源请求 设备根据该白频谱资源请求消息中的需求信息，为白频语设备分配白频谱资源 或是向白频谱数据库查询是否有合适的白频谱资源。 另外， 当需要对白频谱设 备使用的白频谱更新或因白频谱资源请求设备需要白频谱设备来分流业务时 主动发起用于激活白频语设备利用白频谱资源分流业务时进行资源更新。
本发明实施例提供的白频谱设备，通过向白频谱资源请求设备发送携带自 身的第二白频谱需求信息的白频谱资源请求消息， 即指示自己的白频语能力， 白频谱设备与白频谱资源请求设备之间的交互可以通过现有协议建立，使得白 频语设备无需与白频语数据库建立连接来获取白频谱资源 ,不需要定义新的接 口支持 PAWS协议。
图 12为本发明白频谱资源获取系统实施例的结构示意图，如图 12所示， 本 发明实施例提供的系统包括： 白频谱资源请求设备 31、 白频语数据库 32、 白频 谱设备 33。
如图 12所示的系统，白频语设备 33可以直接与白频谱资源请求设备 31建立 连接， 白频谱资源请求设备 31基于 PAWS协议与白频谱数据库通信， 负责获取 可用的白频谱资源。但是， 白频谱设备 33无需与白频谱数据库直接建立连接来 获取白频谱资源， 其可通过除 PAWS协议外的现有协议， 例如， RRC协议或是 Diameter协议等进行通信。 因此， 对于白频谱设备， 不需要定义新的接口支持 PAWS协议。
具体的， 本发明实施例中， 白频谱设备 33例如可以是主白频谱设备 331或 从属白频谱设备 332,主白频谱设备 331可以基于现有协议与白频谱资源请求设 备 31建立连接以获取白频谱资源， 从属白频谱设备 332除了可以基于现有协议 与白频谱资源侵权设备 31建立连接外， 也可以连接在主白频谱设备 331上， 通 过主白频语设备 331获取可用白频谱资源。
