Description

一种频谱资源管理方法、 设备及系统 技术领域 本发明涉及通信领域, 尤其涉及一种频谱资源管理方法、 设备及系 统。
背景技术
随着数据通信的迅速发展, 用户对数据传输的需求日益增加, 使得 无线网络的负载越来越重, 为了充分利用频谱资源, 满足日益增加的数 据传输需求, 载波聚合技术应运而生, 载波聚合就是将两个或更多的成 员载波聚合构成一个大带宽信道来传输数据, 从而满足更大的带宽和更 高的数据传输速率的需求。 载波聚合可以分为连续载波聚合与非连续载 波聚合。 目前, 在 802.11的现有机制中, 通过把信道带宽划分为主载波和辅 载波, 增加信号传输带宽来提高数据传输的峰值速率。 802.11 中的机制 类似于载波聚合, 这种机制需要通过载波竟争接入。 例如, 在信道带宽 为 160MHz时, 载波竟争接入的顺序为主 20MHz载波, 辅 20MHz载波, 辅 40MHz载波, 辅 80MHz载波。 依照这样的顺序, 只有前一个载波允 许接入使用时, AP ( Access Point, 接入点) 设备或者 STA ( Station, 用户设备) 才会进行后一个载波的竟争接入, 最后把允许接入的载波组 合在一起构成一个大带宽信道来传输数据。
但是, 目前每个 AP设备管理的频语资源只建立一个 BSS( Basic Service Set , 基本服务集), BSS是独立的通信系统, 相应的, 该 BSS 对应的频谱资源划分为主载波和辅载波, 无论该 BSS的带宽多大, 其主载波总是固定不变的, 当主载波所在的频谱资源被其它设备占 用时, 该频谱资源就不能用来传输 AP设备管理的唯一的 BSS 的数 据, 由此导致 AP 设备管理的频谱资源上数据的传输会受到影响, 降低 AP设备管理的频谱资源上的数据传输效率。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进 行清楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而不是全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没 有作出创造性劳动前提下所获得的所有其他实施例, 都属于本发明保护的 范围。
本发明中术语 "和 /或" , 仅仅是一种描述关联对象的关联关系, 表 示可以存在三种关系, 例如, A和 /或 B , 可以表示: 单独存在 A, 同时存 在 A和 B , 单独存在 B这三种情况。 另外, 本文中字符 "/" , 一般表示前 后关联对象是一种 "或" 的关系。
本发明实施例提供的频谱资源管理方法, 应用于无线局域网, 所述无 线局域网包括多个 AP设备和多个用户设备,每个所述 AP设备管理特定的 一段频谱资源, AP设备可以通过 AP设备管理的频谱资源和相应的用户 设备进行数据传输。
本发明实施例提供一种频谱资源管理方法, 应用于 AP设备, 如图 1 所示, 包括:
步骤 101、 将 AP设备管理的频谱资源划分为至少两个成员载波。 示例的, AP设备可以扫描所述 AP设备管理的频谱资源的前 k个信 道, 所述 k为大于 1的整数; 判断所述前 k个信道的带宽之和是否大于所 述 AP设备的最大支持带宽; 若所述前 k个信道的带宽之和大于所述 AP 设备的最大支持带宽, 获取所述前 k个信道中所有可用的信道, 将所述可 用信道划分得到至少两个成员载波。
步骤 102、 分别为每个所述成员载波建立 BSS。
步骤 103、 将所述 BSS中的一个或多个分配给用户设备。
用户设备可以在 AP设备分配的频谱资源中进行数据传输, 具体的, 可以和其他用户设备传输数据, 也可以与 AP设备传输数据, 本发明对此 不做限定。
这样一来, 由于 AP设备将所述 AP设备管理的频谱资源划分为至少 两个成员载波, 分别为每个所述成员载波建立基本服务集 BSS , 因此最终 AP设备建立了至少两个 BSS , 即使存在任意一个 BSS所在的频谱资源被 其它设备占用, AP设备管理的其他 BSS也可以不受影响, 继续进行数据 传输, 因此提高了 AP设备管理的频谱资源上的数据传输效率。
进一步的, 在步骤 102之后, 所述方法还包括:
广播信标帧, 所述信标帧包括 BSS 信息, 以便于用户设备根据所述 BSS信息进行 BSS的检测; 或, 针对各个用户设备的探测请求帧回应探测 响应帧, 所述探测响应帧包括所述 BSS信息。
示例的, 所述 BSS信息可以包括 BSS聚合指示, 所述 BSS聚合指示 用于指示所述 AP设备管理的 BSS支持 BSS聚合, 需要说明的是, AP设 备管理的 BSS至少包括该 AP设备建立的 BSS。 所述 BSS信息还可以包括 BSS分类信息和 /或 BSS聚合列表。 所述 BSS分类信息用于指示所述 AP 设备建立的 BSS 的类别, 所述 BSS聚合列表记录了所述 AP设备建立的 BSS 的身份标识。 用户设备可以通过判断获取的 BSS 信息是否包括 BSS 聚合指示来判断该 BSS是否支持载波聚合, 当获取的 BSS信息包括 BSS 聚合指示, 则判断该 BSS支持载波聚合; 当获取的 BSS信息不包括 BSS 聚合指示, 则判断该 BSS不支持载波聚合。
可选的, 所述信标帧还可以包括功率约束信息; 或, 所述探测响应帧 还包括功率约束信息, 这样一来, 用户设备可以根据所述功率约束信息获 取所述用户设备的本地最大发射功率, 所述功率约束信息记录了功率约束 值, 可选的, 用户设备可以获取所述用户设备的额定最大发射功率, 将所 述额定最大发射功率与所述功率约束值做差得到所述本地最大发射功率; 获取所述用户设备的法定最大发射功率; 在所述本地最大发射功率和所述 法定最大发射功率中选择最小的发设备功率作为所述用户设备的实际最大 发射功率。 这样在后续数据传输过程中, 用户设备的发射机正常工作的发 射功率需要小于或等于所述用户设备的实际最大发射功率, 这样能够减小 数据传输过程中产生的噪声。 所述用户设备的实际最大发射功率获取的过 程可以称为 TPC ( Transmission Power Control, 传输功率控制 ) 过程。 需要说明的是, AP设备在分别为每个所述成员载波建立 BSS之后, 还可以在所述 AP设备管理的频语资源中增加 BSS; 和 /或, 在所述 AP设 备管理的频谱资源中删除 BSS。 这样可以实现对 BSS的增加或删除等重配 置管理, AP设备给各个用户设备的分配的 BSS都可以灵活调整, 提高了 对 BSS管理的灵活性。
示例的, 当需要在所述 AP设备管理的频语资源中增加 BSS 时, AP 设备可以获取所述 AP设备管理的频谱资源的未使用信道; 扫描所述未使 用信道中第 n个信道, 所述 n为大于或等于 1的整数; 判断所述信道是否 可用; 若所述信道可用, 判断已使用信道与扫描到的前 n个信道的带宽之 和是否大于 AP设备的最大支持带宽; 若所述已使用信道与所述前 n个信 道的带宽之和大于所述 AP设备的最大支持带宽, 则将前 n- 1 个可用信道 划分得到至少一个成员载波, 分别为每个所述成员载波建立 BSS , 添加所 述 BSS至 BSS聚合列表。
当需要在所述 AP设备管理的频谱资源中删除 BSS时, AP设备可以 获取所述 AP设备管理的频谱资源的已使用信道; 测量所述已使用信道中 第 m个信道, 所述 m为大于或等于 1的整数; 判断所述信道是否可用; 若 所述信道不可用,删除所述信道上的 BSS ,在 BSS聚合列表删除所述 BSS。
在所述 AP设备管理的频语资源中增加 BSS之后, 和 /或, 在所述 AP 设备管理的频谱资源中删除 BSS之后, 由于 AP设备进行了 BSS的增加或 删除, 相应的 AP设备管理的用户设备的设备相关信息产生了变化, 本发 明实施例以第一用户设备为例 , AP设备可以生成第一用户设备的设备相关 信息; 在所述第一用户设备的主 BSS中向所述第一用户设备下发所述设备 相关信息, 以便于所述第一用户设备比较所述第一用户设备本地保存的设 备相关信息与所述第一用户设备接收的所述设备相关信息, 并根据比较结 果重新配置所述第一用户设备本地的设备相关信息。
特别的,在 AP设备将所述 BSS中的一个或多个分配给用户设备之前, 需要和相应的用户设备建立连接,依然以第一用户为例, AP设备接收所述 第一用户设备发送的请求信息, 所述请求信息通过第一 BSS传输; 根据所 述请求信息将所述第一 BSS设置为所述第一用户设备的主 BSS , 以使得所 述 AP设备通过所述主 BSS与所述第一用户设备建立连接。 在与第一用户 设备建立连接之后, AP设备将所述 BSS 中的一个或多个分配给第一用户 设备, 具体的, AP设备首先在所述第一用户设备的主 BSS 中向所述第一 用户设备发送 BSS聚合列表; 然后, 在所述第一用户设备的主 BSS中向所 述第一用户设备发送 BSS测量信息,所述 BSS测量信息指示测量所述 BSS 聚合列表中的待测量 BSS ; 在所述主 BSS中接收所述第一用户设备上报的 所述待测量 BSS的信道质量,以及第一用户设备所能支持的载波聚合能力; 根据所述待测量 BSS的信道质量, 以及第一用户设备所能支持的载波聚合 能力生成所述第一用户设备的主 BSS指示和辅 BSS列表, 所述辅 BSS列 表中包括至少一个辅 BSS指示,所述主 BSS指示用于指示所述第一用户设 备需要连接的主 BSS , 所述辅 BSS指示用于指示所述第一用户设备需要连 接的辅 BSS; 最后, 向所述第一用户设备下发第一用户设备的设备相关信 息, 所述第一用户设备的设备相关信息包括所述第一用户设备的主 BSS指 示和辅 BSS列表。
特别的, 所述 BSS列表中的 BSS可以来自不同情况下构建的 BSS , 例如, 所述 AP设备为所述第一用户设备分配的辅 BSS是所述 AP设备管 理的 BSS; 和 /或, 所述 AP设备为所述第一用户设备分配的辅 BSS是其他 AP设备管理的 BSS; 和 /或, 所述 AP设备为所述第一用户设备分配的辅 BSS是由至少两个用户设备建立的 BSS , 其中, 所述至少两个用户设备既 可以包括第一用户设备, 也可以不包括第一用户设备, 本发明对此不做限 定。
需要说明的是, AP设备为该 AP设备管理的其他的用户设备分配 BSS 的过程可以参考上述为第一用户设备分配 BSS的过程, 本发明对此不再赘 述。
进一步的,在 AP设备将所述 BSS中的一个或多个分配给用户设备之 后, AP设备还可以对第一用户设备进行管理和配置, 所述管理和配置过程 可以包括:对第一用户设备的认证( authentication )响应、关联( association ) 响应和重新关联响应以及解除认证响应和解除关联响应, 还可以包括对第 一用户设备的认证请求、解除认证请求和解除关联请求以及 DF S ( Dynamic frequency selection , 动态频率选择) 过程。
示例的, 在认证响应过程中, ΑΡ设备可以在所述主 BSS中接收所述 第一用户设备发送的认证请求; 根据所述认证请求生成认证响应信息; 在 所述主 BSS向所述第一用户设备发送所述认证响应信息。
在关联响应过程中, 可以在所述主 BSS 中接收所述第一用户设备发 送的关联请求; 根据所述关联请求生成关联响应信息; 在所述主 BSS向所 述第一用户设备发送所述关联响应信息。
在重新关联响应过程中, ΑΡ设备可以在所述主 BSS中接收所述第一 用户设备发送的重新关联请求;根据所述关联请求生成重新关联响应信息; 在所述主 BSS向所述第一用户设备发送所述重新关联响应信息。 在解除认证响应过程中, AP设备可以在所述主 BSS中接收所述第一 用户设备发送的解除认证请求; 根据所述解除认证请求生成解除认证响应 信息; 在所述主 BSS向所述第一用户设备发送所述解除认证响应信息。

在 DFS过程中, AP设备可以主动进行测量, 例如获取静默时间段; 在所述静默时间段测量所述 AP设备的信道列表中是否存在雷达信号, 所 述信道列表记录了当前所述 AP设备的可用信道;当所述 AP设备的信道列 表中存在雷达信号, 获取所述存在雷达信号的信道, 获取位于所述存在雷 达信号的信道所在载波上的 BSS作为无效 BSS ; 生成信道切换声明, 所述 信道切换声明中指示替换所述无效 BSS的新的 BSS; 广播所述信道切换声 明, 若所述第一用户设备所连接的 BSS为所述无效 BSS , 第一用户设备可 以根据所述信道切换声明将连接的无效 BSS切换至新的 BSS上。 AP设备 可以指示第一用户设备进行测量, 例如, 获取静默时间段; 生成测量请求 信息, 所述测量请求信息包括所述静默时间段; 向第一用户设备发送所述 测量请求信息, 以便于所述第一用户设备在所述静默时间段测量所述第一 用户设备的信道列表中是否存在雷达信号, 所述信道列表记录了当前所述 第一用户设备的可用信道; 接收所述第一用户设备发送的测量响应信息, 所述测量响应信息指示第一用户设备的信道列表中是否存在雷达信号; 当 所述测量响应信息指示第一用户设备的信道列表中存在雷达信号, 获取位 于所述存在雷达信号的信道所在载波上的 BSS作为无效 BSS; 生成信道切 换声明, 所述信道切换声明中指示替换所述无效 BSS的新的 BSS; 向所述 第一用户设备发送所述信道切换声明。
需要说明的是, 所述静默时间段为雷达信号测量时间段, 在该静默时 间段中除测量雷达信号的设备在进行信道测试外, 其他在需要测量的信道 中传输数据的设备停止数据的传输。 例如, 当 AP设备在所述静默时间段 测量所述 AP设备的信道列表中是否存在雷达信号时, 相应的用户设备停 止在所述 AP设备的信道列表中的信道中的数据传输。
特别的, AP 设备还可以获取各个用户设备的额定最大发射功率; 在 所述各个用户设备的额定最大发射功率中筛选得到最大的发射功率作为所 述 AP设备的最大发设功率, 这样在后续数据传输过程中, AP设备的发射 机正常工作的发射功率需要小于或等于所述 AP设备的最大发设功率, 这 样能够减小数据传输过程中产生的噪声。 本发明实施例提供一种数据传输方法,应用于用户设备,如图 2所示, 包括:
步骤 201、 获取 AP设备分配给所述用户设备的主 BSS和辅 BSS。 需要说明的是, 在步骤 201之前, 用户设备还需要和 AP设备建立连 接, 可选的, 用户设备判断检测到的 BSS是否支持 BSS聚合, 所述检测到 的 BSS为所述 AP设备建立的 BSS;判断所述用户设备是否支持 BSS聚合; 当所述检测到的 BSS支持 BSS聚合且所述用户设备支持 BSS聚合, 在所 述检测到的 BSS中向管理所述检测到的 BSS的 AP设备发送请求信息, 以 便于与所述 AP设备建立连接后获取所述 AP设备为所述用户设备分配的主 BSS和辅 BSS。
所述获取 AP设备分配给所述用户设备的主基本服务集 BSS和辅 BSS 具体包括: 接收所述 AP设备发送的当前的主 BSS的 BSS聚合列表, 或者 获取所述用户设备本地保存的当前的主 BSS 的 BSS聚合列表, 所述 BSS 聚合列表记录了至少一个待测量 BSS; 接收所述 AP设备发送的 BSS测量 信息, 或者获取所述用户设备本地保存的 BSS测量信息, 所述 BSS测量信 息记录有测量规则; 根据所述 BSS测量信息测量所述待测量 BSS; 在所述 主 BSS中向所述 AP设备发送测量到的所述待测量 BSS的信道质量, 以及 用户设备所能支持的载波聚合能力, 以便于所述 AP设备根据所述待测量 BSS的信道质量, 以及所述用户设备所能支持的载波聚合能力生成所述用 户设备的主 BSS指示和辅 BSS列表, 所述辅 BSS列表中包括至少一个辅 BSS指示, 所述主 BSS指示用于指示所述用户设备需要连接的主 BSS , 所 述辅 BSS指示用于指示所述用户设备需要连接的辅 BSS; 接收所述 AP设 备下发的设备相关信息, 所述设备相关信息包括所述主 B S S指示和所述辅 BSS列表。
特别的, 所述 BSS列表中的 BSS可以来自不同情况下构建的 BSS , 例如, 所述 AP设备为所述第一用户设备分配的辅 BSS是所述 AP设备管 理的 BSS; 和 /或, 所述 AP设备为所述第一用户设备分配的辅 BSS是其他 AP设备管理的 BSS ; 和 /或, 所述 AP设备为所述第一用户设备分配的辅 BSS是由至少两个用户设备建立的 BSS , 其中, 所述至少两个用户设备既 可以包括本地的用户设备, 也可以不包括本地的用户设备, 本发明对此不 做限定。
步骤 202、 在所述主 BSS和所述辅 BSS中进行数据的传输。
其中, 所述用户设备在所述主 BSS中接受所述 AP设备的管理。 示例 的, 用户设备可以在所述主 BSS中接收所述 AP设备下发的新的设备相关 信息,所述新的设备相关信息是所述 AP设备在所述 AP设备管理的频谱资 源中增加 BSS之后, 和 /或, 在所述 AP设备管理的频谱资源中删除 BSS 之后生成的; 比较本地保存的设备相关信息与所述新的设备相关信息; 若 所述本地保存的设备相关信息中的主 B S S指示与所述新的设备相关信息中 的主 BSS指示不同, 将用户设备切换至所述新的设备相关信息中的主 BSS 指示所指示的主 BSS中;若所述本地保存的设备相关信息中的辅 BSS列表 与所述新的设备相关信息中的辅 BSS列表不同, 用所述新的设备相关信息 中的辅 BSS列表更新所述本地保存的设备相关信息中的辅 BSS列表。
这样一来, 由于用户设备获取 AP设备分配的主 BSS和辅 BSS , 每个 BSS是独立的通信系统,当在所述主 BSS和所述辅 BSS中进行数据的传输 时, 即使存在一个 BSS所在的频谱资源被其它设备占用, 所述主 BSS和所 述辅 BSS中其他的 BSS也可以继续进行数据传输,因此提高了用户设备的 数据传输效率。
进一步的, 在步骤 201中判断所述用户设备是否支持 BSS聚合之前, 用户设备可以获取各个 BSS上的信标帧,根据所述信标帧中的 BSS信息检 BSS; 或, 向各个 BSS发送探测请求, 根据接收到的探测响应帧来检测 BSS。 若所述信标帧中的 BSS信息中包括 BSS聚合指示, 则确定所述检测 到的 BSS支持 BSS聚合; 其中, 所述 BSS聚合指示用于指示 AP设备管理 的 BSS支持 BSS聚合。 进一步的, 所述信标帧还可以包括功率约束信息或 所述探测响应帧还包括功率约束信息, 用户设备还可以根据所述功率约束 信息获取所述用户设备的本地最大发射功率, 所述功率约束信息记录了功 率约束值, 用户设备可以获取所述用户设备的额定最大发射功率, 将所述 额定最大发射功率与所述功率约束值做差得到所述本地最大发射功率; 获 取所述用户设备的法定最大发射功率; 在所述本地最大发射功率和所述法 定最大发射功率中选择最小的发设备功率作为所述用户设备的实际最大发 射功率。 这样在后续数据传输过程中, 用户设备的发射机正常工作的发射 功率需要小于或等于所述用户设备的实际最大发射功率, 这样能够减小数 据传输过程中产生的噪声。 所述用户设备的实际最大发射功率的获取过程 可以称为 TPC ( Transmission Power Control, 传输功率控制 ) 过程。
需要说明的是,在所述获取 AP设备分配给所述用户设备的主 BSS和 辅 BSS之后, 用户设备还可以接收 AP设备的多种管理, 如认证、 关联、 保密 ( confidentiality ) 、 切换 ( transition ) 和 DFS等管理。
当 AP设备进行认证管理时,用户设备首先可以生成认证请求; 然后, 在所述主 BSS 中向所述 AP设备发送所述认证请求, 以便于所述 AP设备 根据所述认证请求生成认证响应信息; 最后, 在所述主 BSS接收所述 AP 设备发送的所述认证响应信息。
当 AP设备进行关联管理时,用户设备首先可以生成关联请求; 然后, 在所述主 BSS 中向所述 AP设备发送所述关联请求, 以便于所述 AP设备 根据所述关联请求生成关联响应信息; 最后, 在所述主 BSS接收所述 AP 设备发送的所述关联响应信息。
当 AP设备进行重新关联管理时, 用户设备首先可以生成重新关联请 求; 然后, 在所述主 BSS中向所述 AP设备发送所述重新关联请求, 以便 于所述 AP设备根据所述重新关联请求生成重新关联响应信息; 最后, 在 所述主 BSS接收所述 AP设备发送的所述重新关联响应信息。
当 AP设备进行解除认证管理时, 用户设备首先可以生成解除认证请 求; 然后, 在所述主 BSS中向所述 AP设备发送所述解除认证请求, 以便 于所述 AP设备根据所述解除认证请求生成解除认证响应信息; 最后, 在 所述主 BSS接收所述 AP设备发送的所述解除认证响应信息。
当 AP设备进行解除关联管理时, 用户设备首先可以生成解除关联请 求; 然后, 在所述主 BSS中向所述 AP设备发送所述解除关联请求, 以便 于所述 AP设备根据所述关联请求生成解除关联响应信息; 最后, 在所述 主 BSS接收所述 AP设备发送的所述解除关联响应信息。
当 AP设备进行 DFS管理时, 用户设备首先可以接收 AP设备发送的 测量请求信息, 所述测量请求信息包括所述静默时间段; 然后在所述静默 时间段测量所述用户设备支持的信道列表中是否存在雷达信号; 最后, 向 所述 AP设备发送测量响应信息, 所述测量响应信息指示所述用户设备支 持的信道列表中是否存在雷达信号; 当所述测量响应信息指示用户设备支 持的信道列表中存在雷达信号, 获取 AP设备发送的信道切换声明。
用户设备也可以主动进行 DFS 管理, 示例的, 用户设备可以获取静 默时间段; 在所述静默时间段测量所述用户设备的信道列表中是否存在雷 达信号, 所述信道列表记录了当前所述用户设备的可用信道; 当所述用户 设备的信道列表中存在雷达信号, 解除与存在雷达信号的信道的关联。 本发明实施例提供一种频谱资源管理方法, 由于通信系统中可能存在 多个用户设备, 本实施例以第一用户设备为例, 如图 3所示, 包括: 步骤 301、 A P设备将所述 A P设备管理的频谱资源划分为至少两个成 员载波。
示例的, AP设备可以扫描所述 AP设备管理的频谱资源的前 k个信 道, 所述 k为大于 1的整数; 判断所述前 k个信道的带宽之和是否大于所 述 AP设备的最大支持带宽; 若所述前 k个信道的带宽之和大于所述 AP 设备的最大支持带宽, 获取所述前 k个信道中所有可用的信道, 将所述可 用信道划分得到至少两个成员载波。
具体的, AP设备可以执行下述步骤:
al . 扫描所述 AP设备管理的频谱资源的第 k个信道, 所述 k为大于 1的整数。 执行步骤 bl。
bl . 判断所述第 k个信道是否可用。 当所述信道可用, 执行步骤 cl , 当所述信道不可用, 执行步骤 dl。
cl . 判断前 k个信道的带宽之和是否大于 AP设备的最大支持带宽。 当所述前 k个信道的带宽之和不大于 AP设备的最大支持带宽, 执行步骤 dl , 当所述前 k个信道的带宽之和大于 AP设备的最大支持带宽, 执行步 骤 el。
dl .将 k+1得到新的 k, 重复步骤 al至 dl , 直至扫描完所有信道。 执 行步骤 el。
el . 获取前 k个信道的带宽之和大于 AP设备的最大支持带宽的信道 中所有可用的信道, 将所述信道划分为至少两个成员载波。
其中,步骤 cl对前 k个信道的带宽之和是否大于 AP设备的最大支持 带宽的判断, 是考虑到 AP设备的带宽承载能力,通常情况下, 需要将 BSS 的建立在 AP设备的最大支持带宽内。
特别的, 当步骤 301 中, AP设备管理的频谱资源的所有信道扫描完 成后, 前 k个信道的带宽之和仍然小于或等于该 AP设备的最大支持带宽, 则将前 k个信道的带宽划分为至少一个成员载波。 在实际应用中, 所述信 道的带宽通常为 20MHz。 需要说明的是, 在步骤 el 中, 由于前 k个信道 的带宽之和大于 AP设备的最大支持带宽的信道中所有可用的信道中可能 存在多个相邻的可用信道, 也可能存在独立的可用信道, 所述独立的信道 表示该可用信道的相邻信道均为不可用信道, 则将所述信道划分为至少两 个成员载波的过程可以包括: 将所述信道中相邻的两个或多个信道划分为 一个成员载波, 将独立的一个信道划分为一个成员载波。
需要说明的是,本发明实施例提供的频带资源划分方法步骤的先后顺 序可以进行适当调整, 如步骤 bl和 cl的前后顺序可以调换, 步骤也可以 根据情况进行相应增减, 任何熟悉本技术领域的技术人员在本发明揭露的 技术范围内, 可轻易想到变化的方法, 都应涵盖在本发明的保护范围之内, 因此不再赘述。
步骤 302、 AP设备分别为每个所述成员载波建立 BSS。
AP设备可以分别为每个所述成员载波建立 BSS , 所述 BSS建立的过 程可以参考现有技术。
在 BSS建立后, 可以广播信标帧, 所述信标帧包括 BSS信息, 以便 于用户设备根据所述 BSS信息进行 BSS的检测。 所述 BSS信息还可以包 括 BSS聚合指示, 所述 BSS聚合指示用于指示所述 AP设备管理的 BSS 支持 BSS聚合。所述 BSS信息还可以包括 BSS分类信息和 /或 BSS聚合列 表。 所述 BSS分类信息用于指示所述 AP设备建立的 BSS 的类别, 所述 BSS聚合列表记录了所述 AP设备建立的 BSS的 ID( IDentity,身份标识)。 特别的, BSS 分类信息和 /或 BSS 聚合列表的具体形式可以有多种, 示例 的, 所述 BSS聚合列表与 BSS的类别可以位于同一张表中, 如图 4所示, 图 4的表记录了 BSS聚合列表 10和 BSS分类信息 20, BSS聚合列表 10 记录了 BSS的 ID号, 分别为 ID1、 ID2、 ID3、 ID4和 ID5 , BSS分类信 息 20记录每个 BSS的类别, ID1为第一类、 ID2为第一类、 ID3为第二类、 ID4为第二类和 ID5为第一类。 特别的, 也可以为属于同一类别的 BSS建 立一个 BSS聚合列表, 所述 BSS信息包含多个 BSS聚合列表。
这样各个用户设备可以根据所述信标帧获取 AP设备的相关信息, 根 据所述信标帧中的 BSS信息来获取 BSS信息进行 BSS的检测。
特别的, AP 设备也可以针对各个用户设备的探测请求帧回应探测响 应帧, 所述探测响应帧包括所述 BSS信息。 所述 BSS信息可以参考上述信 标帧中的 BSS信息, 本实施例对此不再赘述。
步骤 303、 第一用户设备与 AP设备建立连接。
第一用户设备首先需要对通信系统中的 BSS 进行检测, 示例的, 第 一用户设备可以同时检测多个 BSS , 也可以逐一对通信系统中的 BSS进行 检测。 所述检测过程可以包括主动检测和被动检测两种方式。 其中, 被动 检测可以是第一用户设备获取各个 BSS上的信标帧, 根据所述信标帧中的 BSS信息检测 BSS ; 由于各个 AP设备都在周期性广播其信标帧, 每个信 标帧中都只包括一个 BSS信息, 第一用户设备可以逐一获取信标帧, 也可 以同时获得多个信标帧。 主动检测可以是第一用户设备向各个 B S S发送探 测请求, 所述探测请求通过各个所述 BSS发送至相应的 AP设备, 然后该 AP设备可以返回探测响应帧,然后第一用户设备根据接收到的探测响应帧 来检测 BSS , 其中的探测响应帧包括所述 BSS信息。
当第一用户设备检测到一个 BSS , 第一用户设备首先判断检测到的 BSS是否支持 BSS聚合, 可选的, 第一用户设备可以通过判断获取的 BSS 信息是否包括 BSS聚合指示来判断该 BSS是否支持载波聚合, 当获取的 BSS信息包括 BSS聚合指示, 则判断该 BSS支持载波聚合, 当获取的 BSS 信息不包括 BSS聚合指示, 则判断该 BSS不支持载波聚合; 并且第一用户 设备需要判断所述第一用户设备是否支持 BSS聚合; 当所述检测到的 BSS 支持 BSS聚合且所述第一用户设备支持 BSS聚合, 在所述检测到的 BSS 中向管理所述检测到的 BSS的 AP设备发送请求信息, 以便于与所述 AP 设备建立连接后获取所述 AP设备为所述用户设备分配的主 BSS和辅 BSS。 特别的,当所述检测到的 BSS不支持 BSS聚合或所述第一用户设备不支持 BSS聚合, 第一用户设备继续检测其他 BSS并进行上述判断过程, 本发明 对此不再赘述。
本实施例^ _设所述检测到的 BSS为第一 BSS , 且所述检测到的 BSS 为所述 AP设备建立的 BSS。 则所述请求信息通过第一 BSS传输, AP设备 接收所述第一用户设备发送的请求信息后, 根据所述请求信息将所述第一 BSS设置为所述第一用户设备的主 BSS , 以使得所述 AP设备通过所述主 BSS与所述第一用户设备建立连接, 之后, AP设备便可以在该主 BSS上 为所述用户设备分配主 BSS和辅 BSS , 其中, AP设备便在该主 BSS上为 所述用户设备分配的主 BSS可以与当前的主 BSS相同,也可以与当前的主 BSS不同, 在不同时, 用户设备需要切换至新的主 BSS上。
