Description

负载平衡方法、 装置和系统 技术领域
本发明涉及通信领域, 特别涉及一种负载平衡方法、 装置和系统。 背景技术
在无线网络资源共享的场景中,无线网络资源的提供商可以为多个运营商提供资 源共享服务。不同的运营商可以签约分享不同的资源比例。在图 1显示的异构网络中, 运营商 1和运营商 2在小区 A中各自享有 50%的资源, 在小区 B中各自享有 70%和 30%的资源。在该场景下, 对于运营商 1来说, 如果其在小区 A中所占用的资源比例 已经达到 50%, 就不能再接纳更多的属于运营商 1的终端。
表 1示意了在图 1所示的场景下,为每个运营商预定义的资源共享比例的一个举 例。
Figure imgf000003_0001
在异构网络中, 小区 B 为了接纳更多的终端, 提高整个系统的容量, 可能会扩 大服务范围。 此时, 小区 A会分配 ABS (Almost Blank Subframe, 几乎空子帧) 资 源给小区 B。 虽然 ABS资源的分配可以提高整个系统的吞吐量, 但对于运营商 2来 说, 其在小区 B中所占的资源比例比在小区 A中低, 这就意味着, 运营商 2牺牲了 和运营商 1一样的资源, 却在小区 B中获得了比运营商 2更少的好处。 因此, 这样 对于运营商 2来说不公平。

在本发明实施例中, 为了方便说明, 以异构网络场景中的宏小区为其覆盖范围内 的小小区分配 ABS资源为例, 但本发明实施例并不以此作为限制, 本发明实施例的 负载平衡方法、装置和系统也可以应用于其它资源分配的场景, 其原理与该异构网络 场景类似, 在以下的说明中将不再重复说明。
实施例 1
本发明实施例提供了一种负载平衡方法,该方法可以应用于异构网络场景中的宏 基站, 也即宏小区 (macro cell) 的基站, 该宏基站可以为该宏小区覆盖范围内的小 小区(small cell)分配 ABS资源。 图 2是该方法的流程图, 请参照图 2, 该方法包括: 步骤 201 : 小区的基站为邻小区分配几乎空子帧资源;
其中, 这里的小区是指宏小区, 小区的基站是指宏基站, 相应的, 邻小区是指该 宏小区覆盖范围内的小小区, 这里的邻小区可以是一个, 也可以是两个或两个以上。 其中, 宏基站可以在邻小区有需求时, 为该邻小区分配 ABS资源, 例如, 图 1 所示的场景下, 小区 B扩大服务范围后, 处于小区边缘的终端将受到小区 A的下行 强干扰, 此时小区 A可以通过 X2接口分配 ABS资源给小区 B。 具体的分配方法可 以参考现有技术, 此处不再赘述。
步骤 202: 所述小区的基站接收所述邻小区的基站反馈的与其签约的各运营商的 几乎空子帧资源利用率;
其中, 邻小区在获得了这部分 ABS资源后, 会将其分配给与其签约的各运营商 使用, 并将每个运营商的 ABS资源利用率反馈给宏基站。 由此, 宏基站可以获得上 述每个运营商的 ABS资源利用率。
步骤 203 : 所述小区的基站根据所述各运营商的几乎空子帧资源利用率和非几乎 空子帧资源利用率确定所述各运营商的实际资源使用量。
其中, 宏基站在获得了每个运营商的 ABS资源利用率以后, 可以结合各运营商 对非 ABS资源的利用情况,也即非 ABS资源利用率来确定各运营商的实际资源使用 量。
通过本实施例的方法, 宏基站不是单纯的根据各运营商对非 ABS资源的利用率 来决定是否接纳属于各运营商的终端, 而是进一步考虑了各运营商对其分配出去的 ABS资源的利用情况, 由此避免了资源分配的不均衡。
以下通过举例对此加以说明。
仍以图 1所示的异构网络场景和表 1所示的各运营商的资源共享比例为例,假设 小区 A为小区 B分配的 ABS资源为 40ms (毫秒) ABS分配周期中的四个子帧, 其 中, 运营商 1和运营商 2实际分别使用了其中的 60%和 20%资源。 小区 B的基站将 该信息反馈给小区 A的基站, 小区 A可以综合考虑非 ABS资源和 ABS资源的利用 情况, 得到合理的各运营商的实际负载值, 进而决定是否接纳属于各运营的终端。
在步骤 203的一个实施方式中,所述小区的基站可以根据以下公式确定每个运营 商的实际资源使用量:运营商的实际资源使用量 = (非几乎空子帧资源 *所述运营商的 非几乎空子帧资源利用率 +几乎空子帧资源 *所述运营商的几乎空子帧资源利用率) I (非几乎空子帧资源 +几乎空子帧资源)。 其中, 非几乎空子帧资源 +几乎空子帧资源 即为资源总数。 在本实施方式中,仍以图 1所示的异构网络场景和表 1所示的各运营商的资源共 享比例为例, 假设运营商 1和运营商 2的非 ABS资源利用率分别为 40%和 50%。 其 中,运营商 1的非 ABS资源利用率 =运营商 1非 ABS资源的使用量 /小区 A中所有非 ABS资源。
则根据以上公式:
运营商 1实际负载 =((40-4)*40%+4*60%)/40=42%;
运营商 2实际负载 =((40-4)*5%+4*20%)/40=47%;
因此, 如果不考虑 ABS资源的利用率, 运营商 2的共享比例已经达到 50%, 根 据预先设定的共享比例, 小区 A将不能再接纳运营商 2的终端。 但如果考虑了 ABS 利用率, 运营商 2实际负载为 47%, 小区 A还可以接纳运营商 2的终端。 由此避免 了资源分配的不均衡。
在本实施例的一个实施方式中,该小区的基站在为所述邻小区分配几乎空子帧资 源时,还可以将所述几乎空子帧资源在与其签约的各运营商中的分配比例发送给所述 邻小区的基站。 以提供给该邻小区的基站作为参考以为各运营商分配 ABS资源。
在该实施方式中,以图 1所示的场景为例,小区 A在为小区 B分配 ABS资源时, 可以告知小区 B, 该 ABS资源在各运营商中的分配比例, 建议对方运用该比例为各 运营商分配 ABS资源。
在本实施例的一个实施方式中,该小区的基站还可以接收所述邻小区的基站反馈 的所述几乎空子帧资源在与其签约的各运营商中的分配比例。以便小区的基站可以掌 握其分配出去的 ABS资源在各运营商中的分配比例, 为其确定各运营商的实际资源 使用量作为参考。
在该实施方式中, 邻小区的基站除了反馈各运营商的 ABS资源利用率, 还可以 反馈各运营商的 ABS资源分配比例, 也即该邻小区的基站以怎样的比例为各运营商 分配这部分 ABS资源。 以图 1所示的场景为例, 小区 B在向小区 A反馈各运营商的 ABS资源利用率时, 还可以同时提供该 ABS资源在各运营商中的分配比例, 例如是 按照小区 A建议的分配比例分配的,还是按照各运营商在小区 B的签约情况分配的。 如果是按照小区 A建议的分配比例 (例如各占 50%) 分配的, 也即小区 B将该 ABS 资源按照 50%和 50%的分配比例分配给运营商 1和运营商 2,则小区 B会将该分配比 例告知小区 A; 如果是按照各运营商在小区 B的签约情况 (例如各占 70%和 30%) 分配的, 也即, 小区 B将该 ABS资源按照 70%和 30%的分配比例分配给运营商 1和 运营商 2,则小区 B会将该分配比例告知小区 A。该信息可以为小区 A提供一个参考, 便于其决定各运营商的实际资源使用量。
在本实施例的一个实施方式中, 该小区的基站在为邻小区分配 ABS资源之前, 可以首先确定与其签约的各运营商的资源共享比例。其中, 该资源共享比例可以由该 小区的基站根据各运营商的签约情况设定, 也可以由操作管理和维护 (OAM, Operation Administration and Maintenance) 服务器根据各运营商的签约情况设定, 并 提供给该小区的基站。 当然, 本实施例并不以此作为限制。 在该实施方式中, 在实际 网络运营中, 该资源共享比例可用于判断某运营商的负载是否已经超过签约值, 从而 决定是否继续接纳属于该运营商的终端。
仍以图 1所示的异构网络场景为例,在一个实施方式中,无线资源提供商可以根 据各运营商的签约情况在小区 A 的基站中设定各运营商的资源共享比例, 例如, 运 营商 1和运营商 2在小区 A中各占 50%的资源,在小区 B中各占 70%和 30%的资源, 小区 A的基站可以由此确定运营商 1和运营商 2在小区 A的资源共享比例,同样的, 小区 B的基站也可以由此确定运营商 1和运营商 2在小区 B的资源共享比例。 在另 一个实施方式中,无线资源提供商可以根据各运营商的签约情况在 OAM中设定各运 营商的资源共享比例, 由该 OAM将该资源共享比例提供给小区 A的基站和小区 B 的基站, 小区 A和小区 B的基站可以由此确定运营商 1和运营商 2在各自小区的资 源共享比例。
在本实施例的一个实施方式中,在确定了各运营商的资源共享比例之后, 小区的 基站将还可以与其签约的各运营商的资源共享比例发送给邻小区的基站。
在本实施方式中, 仍以图 1所示的异构网络场景为例, 小区 A和小区 B可以互 相通知与各自签约的各运营商的资源共享比例, 该通知信息可通过 X2接口发送, 也 可以通过 OAM发送。 例如, 小区 A将运营商 1和运营商 2在该小区 A中的资源共 享比例, 即 50%和 50%, 通知邻小区 B; 小区 A同时接收来自邻小区 B提供的各运 营商在小区 B的资源共享比例, 即运营商 1和运营商 2分别享有 70%和 30%的资源。 由此, 小区 A可以参考各运营商在小区 B的资源共享比例为小区 B分配 ABS资源。 同时, 小区 B也可以参考各运营商在小区 A的资源共享比例为各运营商分配 ABS资 在本实施例中, 是以图 1所示的异构网络场景为例, 也即该异构网络场景下存在 两个小区, 但本实施例并不以此作为限制, 在具体实施过程中, 可能存在多个小区, 此时, 每个小区都将与其签约的各运营商的资源共享比例发送给邻小区。 并且, 在图
1所示的异构网络场景中, 是以两个运营商分别与该异构网络场景下的每个小区签约 为例, 在具体实施过程中, 也可能存在与不同小区签约的运营商不同的情况, 此时, 各小区会将与其签约的运营商的资源共享比例发送给邻小区。
通过本实施例的方法,异构网络场景下的宏小区可以确定各运营商的实际资源使 用量, 包括非 ABS资源使用量和 ABS资源使用量, 由此避免了资源分配的不均衡。
实施例 2
本发明实施例提供了一种负载平衡装置, 该装置应用于一个小区的基站,例如异 构网络场景下的宏基站, 由于该装置解决问题的原理与实施例 1的方法类似, 因此其 具体的实施可以参照实施例 1的方法的实施, 内容相同之处不再重复说明。

可选的, 该中央处理器 401还被配置为: 接收所述邻小区的基站反馈的所述几乎 空子帧资源在与其签约的各运营商中的分配比例。 可选的, 该中央处理器 401还被配置为: 根据以下公式确定每个运营商的实际资 源使用量:运营商的实际资源使用量 = (非几乎空子帧资源 *所述运营商的非几乎空子 帧资源利用率 +几乎空子帧资源 *所述运营商的几乎空子帧资源利用率) I (非几乎空 子帧资源 +几乎空子帧资源)。
可选的, 该中央处理器 401还被配置为: 确定与该基站签约的各运营商的资源共 享比例。其中, 该中央处理器 401还被配置为: 根据各运营商的签约情况设定各运营 商的资源共享比例; 也可以被配置为: 根据操作管理和维护服务器设定的各运营商的 资源共享比例确定与该基站签约的各运营商的资源共享比例。

步骤 501 : 小区的基站确定邻小区的基站为其分配的几乎空子帧资源; 其中, 对应实施例 1的步骤 201, 本实施例的小区的基站可以确定宏基站 (在本 实施例中称为邻小区的基站) 为其分配的 ABS资源。
步骤 502: 所述小区的基站将与其签约的各运营商的几乎空子帧资源利用率反馈 给所述邻小区的基站,以便所述邻小区的基站根据所述各运营商的几乎空子帧资源利 用率和非几乎空子帧资源利用率确定所述各运营商的实际资源使用量。
其中, 对应实施例 1 的步骤 202, 本实施例的小区的基站可以将每个运营商的 ABS资源利用率反馈给宏基站。 例如, 小区 B按照每个 PLMN (Public Land Mobile Network, 公共陆地移动网络) 反馈 ABS资源利用率。 该反馈信息可以在 X2接口中 传输, 比如, 可以承载在 ABS status IE里, 但本实施例并不以此作为限制。

在本实施例的一个实施方式中, 如实施例 1所述,宏基站在为本实施例的小区的 基站分配 ABS资源时,还可以将该 ABS资源在各运营商中的分配比例作为参考提供 给本实施例的小区的基站, 则在本实施方式中,本实施例的小区的基站还可以接收所 述邻小区的基站发送的所述几乎空子帧资源在与其签约的各运营商中的分配比例。由 此, 本实施例的小区的基站可以参考该分配比例为各运营商分配这部分 ABS资源。 这里, 本实施例的小区的基站可以参考该分配比例, 但不是必须的, 其可以不考虑该 分配比例, 而是根据与其签约的各运营商的资源共享比例决定各运营商的 ABS资源 的分配比例。
在本实施例的一个实施方式中, 如实施例 1所述,本实施例的小区的基站也可以 在反馈各运营商的 ABS资源利用率之前,确定与其签约的各运营商的资源共享比例。 类似的, 该小区的基站可以根据各运营商的签约情况设定各运营商的资源共享比例; 也可以根据操作管理和维护服务器设定的各运营商的资源共享比例确定与其签约的 各运营商的资源共享比例。
在本实施方式中, 如实施例 1所述, 本实施例的小区的基站还可以将与其签约的 各运营商的资源共享比例发送给邻小区的基站。以便宏基站可以参考各运营商在本实 施例的小区中的资源共享比例为本实施例的小区分配 ABS资源。

在本实施例中, 宏基站 801可以通过实施例 3中所述的基站 400来实现; 基站 802可以通过实施例 6所述的基站 700来实现。 由于在实施例 3和实施例 6中, 已经 对基站 400和基站 700做了详细说明, 其内容被合并于此, 在此不再赘述。
通过本实施例的通信系统,异构网络场景下的宏小区可以确定各运营商的实际资 源使用量, 包括非 ABS资源使用量和 ABS资源使用量, 由此避免了资源分配的不均 衡。
