在现有技术资源状态报告获取的过程中, 在部分或全部请求资源可用 时, 都会由响应端 eNB向请求端 eNB发送资源状态响应消息,请求端 eNB 根据响应消息进行后续的负荷均衡决策。
在实现负荷均衡的过程中, 请求端 eNB所请求的资源中, 有些资源是 进行负荷均衡必须使用的基础资源,而有些资源是可选的; 当响应端的 eNB 缺少基础资源时,将导致请求端 eNB向响应端 eNB的负荷均衡的效果很差 或根本无法实现均衡。
在现有技术中, 当响应端 eNB无法提供部分或全部基础资源且可提供 部分可选资源时,响应端 eNB依然会向请求端 eNB回复资源状态响应消息, 如此, 将导致请求端 eNB继续执行负荷均衡决策, 进而导致请求端 eNB的 负荷进一步加重。 发明内容

以下结合附图对本发明的优选实施例进行详细说明, 应当理解, 以下 所说明的优选实施例仅用于说明和解释本发明, 并不用于限定本发明。
实施例一:
如图 1所示, 本实施例所述资源状态获取方法包括:
步骤 S110: 接收包括基础资源信息的资源状态报告请求消息; 所述基础 资源信息用于指示所述第二基站必须提供的基础资源;
步骤 S120: 根据所述基础资源信息判断所述第二基站是否能提供所述 基础资源, 当所述第二基站不能提供所述基础资源时, 第二基站发送资源 状态失败消息。
在步骤 S110中, 所述资源状态报告请求消息可以是第一基站发送的, 也可以是获取了第一基站资源状态报告请求消息的管理或中继设备(具体 的如网管设备)发送的。
在所述步骤 S120, 判断所述第二基站是否能提供所述基础资源的执行 主体可以是第二基站本身, 也可以是管理所述第二基站的网管设备; 具体 的如何判断可以现有方法中任意一种。 具体的如: 第二基站统计第二基站 当前使用资源量, 通过全部资源与当期使用资源量的差值运算或预设函数 关系计算得到可提供的资源, 并再判断是否满足基础资源所需量, 进而可 以实现对是否能提供对应的基础资源的判断。
在所述步骤 S120中所述资源状态失败消息可以是预先存储的, 也可以 是动态生成的; 所述第二基站可以将所述资源状态失败消息直接发送至作 为请求端的第一基站, 也可以发送至可以向第一基站发送信息的中继或控 制设备中, 再由中继或控制设备发送至第一基站。 所述中继或控制设备具 体的如网管设备。 本实施例中所述的资源状态获取方法, 相比于现有方法, 首先判断了 作为响应端的第二基站是否能够为作为请求端的第一基站提供此次资源状 态获取方法中必须使用的基础资源, 若不能提供则第二基站可以通过空口 向第一基站直接发送资源状态失败消息。 从而杜绝了在第二基站无法提供 基础资源时发送资源状态响应消息, 导致请求端的第一基站继续进行负荷 均衡的决策, 从而降低了第一基站的负荷。 与此同时规避了第二基站在基 础资源都不能提供的状态下, 第二基站依然对所有请求资源是否能提进行 判断, 从而同步合理化了资源状态获取方法。
此外, 在所述步骤 S120中判断出第二基站能提供第一基站所需的全部 行, 从而进一步的完成对第二基站的资源状态的获取。
在本实施例中, 所述的基础资源可以是物理资源、 传输网络层负载资 源、 硬件负载资源、 空白子帧以及复合可用资源中的任意一种或多种。 具 体的所述基础资源为上述资源的哪一种, 可以根据第一基站预向第二基站 进行均衡的负荷类型来决定。
实施例二:
本实施例资源状态获取方法包括:
接收包括基础资源信息的资源状态报告请求消息, 所述基础资源信息 用于指示第二基站必须提供的基础资源;
根据所述基础资源信息判断所述第二基站是否能提供所述基础资源, 所述第二基站在不能提供所述基础资源时, 发送资源状态失败消息。 在具体的实施过程中, 在所述资源状态报告请求消息中增设的所述基 础资源信息, 可以是通过各种形式的数据结构进行描述; 而在本实施例中 为了与现有技术的更好的兼容, 以尽量的简化所述基础资源信息的表示, 釆用了以下方式; 所述资源状态报告请求消息还包括请求资源类型信息; 所述请求资源 类型信息用于表示需第二基站提供的请求资源; 所述基础资源信息为标注 各所述请求资源是否为基础资源的指示信息。
请求资源类型信息与基础资源信息的实现方式都有多种。 在本实施例 中结合现有技术中的请求资源类型信息, 釆用指示信息指示请求资源是否 为基础资源, 简化了资源状态报告请求消息, 避免了所述资源状态报告请 求消息中出现两次以上的同一请求资源的指代信息, 从而减少了资源状态 报告请求消息数据量, 且对现有资源状态报告请求消息的数据结构变更少, 从而实现简便易行。
根据本实施例中所述的请求资源信息和基础资源信息的结合表示方 法, 有多种具体实现方式, 而在本实施例中进一步的提出了一种优选的请 求资源信息和基础资源信息的结合表示方法, 具体如下:
所述请求资源类型信息为第一比特位图;
所述基础资源指示信息为与第一比特位图等比特数的第二比特位图; 所述第二比特位图根据与所述第一比特位图的预设映射关系, 在对应 所述基础资源的比特进行标注。
具体的,如图 2a所示为对应于请求资源类型信息的第一比特位图 110; 所述第一比特位图中包含若干个比特, 具体如 32个比特或 64个比特; 第 一比特位图中的一个比特或多个比特组表示了一种资源是否为请求资源。
在本实施例中, 第一比特 111 用来表示物理资源是否为请求资源、 第 二比特 112 用来表示传输网络层负载资源是否为请求资源; 第三比特 113 用来表示硬件负载资源是否为请求资源; 第四比特 114 用来表示复合可用 资源是否为请求资源; 第五比特 115 用来表示空白子帧是否为请求资源。 116代表的是剩余比特对其他资源是否为请求资源的表示。
当比特 111至 116中任意一比特记为 1时表示该比特对应的资源为请 求资源, 否则该比特对应的资源为非请求资源; 或者当对应的比特位记为 0 时表示该比特对应的资源为请求资源, 否则该比特对应的资源为非请求资 源。 具体釆用上述两种中的哪一种指示方式, 可以根据需要进行设置。
具体的, 如图 2b所示为对应于基础资源信息的第二比特位图 120; 所 述第二比特位图 120与所述第一比特位图 110为包括相同比特数的比特位 图。 在第一比特位图 110 中一个比特或多个比特组合表示了一种资源是否 为请求资源, 而在第二比特位图中一个比特或多个比特组合用于指示一个 请求资源是否为基础资源; 在本实施例中, 第一比特 121 用来表示物理资 源是否为基础资源、 第二比特 122用来表示传输网络层负载资源是否为基 础资源; 第三比特 123 用来表示硬件负载资源是否为基础资源; 第四比特 124用来表示复合可用资源是否为基础资源;第五比特 125用来表示空白子 帧是否为基础资源。 126代表的是剩余比特对其他资源是否为请求资源的表 示。
当比特 121至 126中任意一比特为 1时表示该比特对应请求资源为基 础资源, 否则该比特对应的资源为非请求资源; 或者当对应的比特位为 0 时表示该比特对应的请求资源为基础资源, 否则该比特对应的资源为非基 础资源, 具体釆用上述两种中的哪一种指示方式, 可以根据需要进行设置。
在本实施例中, 所述第一比特位图 110与所述第二比特位图 120之间 釆用的预设映射关系为同位置的比特——对应关系, 在具体的实现过程中, 还可以釆用其他的函数关系 (如哈希函数) 来表征映射关系。 然而, 本实 施例所述的映射关系简单、 明了、 且对现有技术的改变小从而易于实现。
实施例三:
如图 3所示, 本实施例资源状态获取方法包括:
步骤 S210: 接收包括基础资源信息的资源状态报告请求消息, 所述基 础资源信息用于指示第二基站必须提供的基础资源; 步骤 S220: 根据所述基础资源信息判断所述第二基站是否能提供所述 基础资源, 是则进入步骤 S230, 否则进入步骤 S250;
所述步骤 S230: 判断所述第二基站是否能提供所述资源状态报告请求 消息中所要求的全部请求资源; 否则进入步骤 S240, 是则进入步骤 S260; 所述步骤 S240:判断所述第二基站是否能提供基础资源以外的部分所述 请求资源,是则进入步骤 S260,否则进入步骤 S250。在具体的实现过程中, 在执行步骤 S240之前, 还包括判断所述资源状态报告请求消息中是否携带 有 "允许部分测量对象获取成功的指示", 所述测量对象对应于所述请求资 源。 仅有在包括上述 "允许部分测量对象获取成功的指示" 且指示允许时, 才进行所述步骤 S240, 否则流程结束或转入其他相应的流程。
步骤 S250为所述第二基站发送资源状态失败消息;
步骤 S260为所述第二基站发送资源状态响应消息。
在所述步骤 S210所接收的资源状态报告请求消息可以来自请求端的第 一基站;
所述步骤 S250以及所述步骤 S260的执行主体都可以是作为响应端的 第二基站; 所述资源状态失败消息以及所述资源状态响应消息可以直接发 送至作为请求端的第一基站。
在本实施例中, 在步骤 S220中首先判断了第二基站是否能提供基础资 源,能提供再进行后续步骤 S230以及步骤 S240,否则直接进入了步骤 S250, 从而能有效的避免直接进行部分请求资源是否可以提供的判断, 进而向第 一基站发送资源状态响应消息, 从而造成第一基站在无法实现负荷均衡的 情况下, 负荷进一步加重的问题。
在实施例一至实施例三, 所述方法还可以包括所述第一基站接收到第 二基站发送资源状态消息后, 结束本次资源状态获取流程、 或转入其他的 失败处理步骤或其他转入处理步骤。 综合上述实施例一至实施例三所述的 资源状态获取方法, 相对于现有方法, 增加了响应端基站是否能提供基础 资源的判断, 从而能在响应端基站无法提供基础资源时, 及时的结束资源 状态获取的流程, 优化了资源状态获取的方法, 更为重要的是避免了请求 端基站在响应端基站无法提供基础资源时仍进行负荷均衡的决策, 反而导 致请求端基站的负荷进一步加重的问题。 实施例四:
如图 4所示, 本实施例提供了一种资源状态获取方法, 所述方法包括: 步骤 S310: 第一基站向第二基站发送包括基础资源信息的资源状态报 告请求消息; 所述基础资源信息用于指示所述第二基站必须提供的基础资 源;
步骤 S320: 第二基站接收所述第一基站发送的所述资源状态报告请求 消息;
步骤 S330: 所述第二基站根据所述资源状态报告请求消息, 判断所述 第二基站是否能提供所述基础资源,
步骤 S340:当所述步骤 S330中的判断出第二基站不能提供所述基础资 源时(即判断结果为否时), 则所述第二基站向所述第一基站发送资源状态 失败消息。
在本实施例中, 所述的基础资源可以是任意有关于负荷均衡所要用到 的资源, 具体的可以是物理资源、 传输网络层负载资源、 硬件负载资源、 空白子帧以及复合可用资源中的任意一种或多种。
此外,在所述步骤 S330中判断出第二基站能提供第一基站基础资源时, 则可以釆用现有方法中资源状态获取方法中的步骤继续进行, 从而进一步 的完成对第二基站的资源状态的获取。
相对于现有技术中资源状态报告请求消息, 本实施例中资源状态获取 方法, 所述资源状态报告请求消息, 增设了基础资源信息。 增设所述基础 资源信息的方法有多种, 以下提供一个示例。
所述示例为根据需要均衡的负荷类型, 每一负荷类型所必须使用的资 源则可以预先定义为基础资源。 故在形成资源状态报告请求信息时, 根据 负荷类型从相应的存储介质中读取所述基础资源信息即可。
通过基础资源信息的增设, 在第二基站进行后续请求资源是否能提供 时, 先进行响应端基站是否能提供基础资源的判断, 从而避免了在第二基 站无法提供基础资源情况下, 第二基站依然向第一基站发送资源状态响应 消息, 导致第一基站根据所述响应消息继续进行负荷均衡决策。 第一基站 在上述情况下进行负荷均衡决策, 负荷均衡无法达到预期的效果或完全不 能实现的, 反而加重了第一基站的负荷, 从而有悖于进行资源状态获取以 实现负荷均衡且减轻第一基站负荷的初衷。
实施例五:
如图 5所示, 本实施例提供了一种资源状态获取装置, 所述装置包括: 接收单元 210, 配置为接收资源状态报告请求消息; 所述资源状态报告 请求消息中包括基础资源信息; 所述基础资源信息用于指示所述第二基站 必须提供的基础资源;
判断单元 220, 配置为判断所述第二基站是否能提供所述基础资源; 发送单元 230, 配置为在所述第二基站不能提供所述基础资源时,发送 资源状态失败消息。
所述接收单元 210可以包括空中接口。 所述资源状态报告请求消息可 以是由请求端的第一基站发送的。
所述判断单元 220 的具体结构可以是电子元器件如比较器、 比较器与 放大器等信号处理元器件的组合, 还可以是运行有实现相应功能软件的处 理器。 所述处理器可以是单片机、 数字信号处理器, 还可以是可编程阵列 或中央处理器等。 所述发送单元 230可以是有线或无线的发送器件, 具体的如发送天线 等。 所述资源状态失败消息可以是预先设置的信息, 还可以是动态生成的 信息。 当所述资源状态失败消息仅是简单的提示失败信息时, 可以预先设 置并存储, 若所述资源状态失败消息还包括第二基站不能提供相应请求资 源的原因解析信息时, 可以选择动态生成。 釆用静态的预先存储所述资源 状态失败消息, 则所述资源状态获取装置还可以包括存储介质或从外设读 取所述资源状态失败消息的数据接口。 釆用动态生成所述资源状态失败消 息时, 则所述资源状态获取装置还可以包括由资源状态失败消息生成单元。
本实施例所述资源状态获取装置, 可以集成在第二基站上的装置, 构 成第二基站一部分, 也可以是独立于所述第二基站的装置且通过有线或无 线的连接方式与所述第二基站连接; 具体结构可以根据需求进行设置。 在 本实施例中优选集成在所述第二基站上。
为了简化资源状态报告请求消息, 避免多次出现同一请求资源的指代 信息, 针对上述情况, 本实施例做了进一步改进, 所述资源状态报告请求 消息还包括请求资源类型信息; 所述请求资源类型信息用于表示需第二基 站提供的请求资源;
所述基础资源信息为各所述请求资源是否为基础资源的指示信息。 在本实施例中基础资源信息为对应各请求资源的指示信息, 实现简便, 对现有技术的改进少。
进一步的, 在上述结构的基础上, 提供了一种简化资源状态报告请求 消息的具体实现方式, 但不局限以下实现方式:
所述请求资源类型信息为第一比特位图;
所述基础资源指示信息为与第一比特位图等比特数的第二比特位图; 所述第二比特位图根据与所述第一比特位图预设映射关系, 在对应所 述基础资源的比特进行标注。 所述预设映射关系可以是同位置比特的顺序对应, 也可以是釆用还是 函数关系交叉映射, 在具体的实现过程中优先釆用第一比特位图与第二比 特位图的顺序映射。 釆用顺序映射, 映射关系清楚明了, 实现简便。
在本实施例中, 所述基础资源为所有请求资源中的任意一种, 具体的 所述基础资源为物理资源块物理资源、 传输网络层负载资源、 硬件负载资 源、 空白子帧以及复合可用资源中的任意一种或多种的组合。
在本实施例中, 所述的资源状态获取装置, 用于负荷均衡的资源状态 报告的获取, 可以有效避免第二基站在其自身缺少第一基站所请求的基础 资源的情况下, 向第一基站发送资源状态响应消息, 从而能有效避免第一 基站在第二基站无法提供所需基础资源的情况下进行负荷均衡决策, 形成 的第一基站既无法向第二基站进行负荷的转移且第一基站因为进行资源状 态获取和负荷均衡负荷进一步繁重的问题。 实施例六:

本实施例中, 所述的资源状态获取系统, 在第一基站 310 的第一发送 单元 311 所发送的资源状态报告请求信息中包括了基础资源信息, 在第二 基站 320中增设了判断单元配置为判断第二基站 320是否能提供基础资源 信息中所需的基础资源, 从而避免了在进行资源状态获取时, 因为处理负 荷转移失败导致的第一基站 310负荷繁重度进一步加剧的问题。
本发明实施例还提供一种计算机存储介质, 所述计算机存储介质中存 储有计算机可执行指令, 所述计算机可执行指令用于执行权利要求实施例 一至实施例四中任意技术方案所述资源状态获取方法。 所述计算机存储介 质具体可为 U盘、 光盘或 DVD等非瞬间存储介质。
