具体实施方式 以下描述中， 为了说明而不是为了限定， 提出了诸如特定系统结构、 接口、 技术之类的具体细节， 以便透彻理解本申请。 然而， 本领域的技术 在其它情况中， 省略对众所周知的装置、 电路以及方法的详细说明， 以免 不必要的细节妨碍本申请的描述。
参阅图 1 , 图 1是本申请数据分流系统一实施方式的结构示意图。 本申 请的数据分流系统包括： 第一耗流基站 110, 供流基站 120以及第二耗流基 站 130。 其中， 分流区 140为第一耗流基站 110所覆盖小区、 供流基站 120 所覆盖小区、 第二耗流基站 130所覆盖小区的重叠区域。 所以， 位于分流 区 140内， 并且原来是利用第一耗流基站 110进行通信的用户设备可以分 流到供流基站 120。 同样地， 位于分流区 140内， 并且原来是利用第二耗流 基站 130进行通信的用户设备也可以分流到供流基站 120。 即， 供流基站 120可以同时为第一耗流基站 110以及第二耗流基站 130分流。
在第一耗流基站 110尚未利用供流基站 120进行分流前， 第二耗流基 站 130已利用供流基站 120进行分流。 当第一耗流基站 110发出分流请求 时， 第二耗流基站 130则计算自身可让出的所占据的供流基站 120的分流 资源数量， 并将这部分分流资源让给第一耗流基站 110。
通常地， 如果第一耗流基站 110以及第二耗流基站 130为宏基站时， 则供流基站 120为微基站； 如果第一耗流基站 110以及第二耗流基站 130 为微基站时， 则供流基站 120为微微基站； 如果第一耗流基站 110以及第 二耗流基站 130为微微基站时， 则供流基站 120为毫微微基站。
参阅图 2, 图 2是本申请数据分流方法一实施方式的流程图。 本实施方 式的数据分流方法包括如下步骤：
S201： 供流基站接收第一耗流基站在空口负载超过第一门限时所发送 的分流请求。
第二耗流基站利用供流基站的分流资源进行分流时， 如果第一耗流基 站的空口负载超过第一门限时， 认为第一耗流基站已经过载， 需要进行分 流。 于是， 第一耗流基站向供流基站发送分流请求。 供流基站接收第一耗 流基站在空口负载超过第一门限时所发送的分流请求。 其中， 分流请求中 包含了第一耗流基站所请求的供流基站的分流资源数量。 一般地， 第一耗 流基站的空口负载超过第一门限的数量等于所请求的供流基站的分流资源 数量。
S202： 供流基站从分流请求中获取第一耗流基站所请求的供流基站的 分流资源数量。
供流基站在接收到第一耗流基站所发送的分流请求后， 从分流请求中 获取第一耗流基站所请求的供流基站的分流资源数量。
S203 : 供流基站根据第一耗流基站所请求的供流基站的分流资源数量 和第二耗流基站可让出的所占据的供流基站的分流资源数量确定分配给第 一耗流基站的分流资源数量。
供流基站在接收到分流请求后， 可以与第二耗流基站进行协商， 根据 所述第二耗流基站历史时间段的物理资源块使用量， 确定所述第二耗流基 站可让出的供流基站的分流资源数量。 供流基站根据第一耗流基站所请求 的供流基站的分流资源数量和第二耗流基站可让出的所占据的供流基站的 分流资源数量确定分配给第一耗流基站的分流资源数量。 如果第二耗流基 站让出的分流资源使得供流基站具有的分流资源大于或等于第一耗流基站 所请求的分流资源， 则将等于第一耗流基站所请求的数量的分流资源分配 给第一耗流基站； 如果第二耗流基站让出的分流资源使得供流基站具有的 分流资源小于第一耗流基站所请求的分流资源， 则将供流基站具有的分流 资源分配给第一耗流基站。
在第一耗流基站获得供流基站的分流资源后， 第一耗流基站利用分配 第一耗流基站的分流资源， 对位于分流区内、 空口负载超过第二门限、 并 且总占据分流资源数量不超过分配给第一耗流基站的分流资源数量的用户 设备进行分流， 其中， 分流区为供流基站所覆盖小区、 第一耗流基站所覆 盖小区、 第二耗流基站所覆盖小区的重叠区域。 即， 要将原来属于第一耗 流基站的用户设备分流到供流基站必须满足三个条件。 （ 1 )用户设备必须 位于分流区内。 （2 )位于分流区内的用户设备的空口负载量超过第二门限。 否则， 将空口负载不超过第二门限的用户设备也分流到供流基站并不能明 显地减少第一耗流基站的负载。 （ 3 )分流到供流基站的多个用户设备所占 据的总分流资源数量不能超过分配给第一耗流基站的分流资源数量。 第一 耗流基站将满足上述条件的用户设备利用分流资源分流到供流基站。 为了 保证通信质量， 也可以对用户设备的业务类型进行判断， 如果是视频业务 或语音业务等， 则不适宜进行分流， 以防止影响视频或语音的流畅。
可以理解， 执行上述方式的主体也可以是第二耗流基站， 或分别与第 一耗流基站、 供流基站或第二耗流基站连接的网络控制器。 特别地， 参阅 图 3 , 如果网络的情况较为复杂时， 采用网络控制器更能提高分流的效果。
并且， 分流的方式可以采用频分模式、 时分模式或者两者的混合模式。 本申请数据分流方法另一实施方式与上一实施方式基本相似。 不同之 处在于， 至少两个耗流基站 （包括第一耗流基站以及第二耗流基站） 的制 式并不相同。 其中， 制式是指基站为 LTE ( Long Term Evolution,长期演进）、 UMTS ( Universal Mobile Telecommunications System, 通用移动通信系统 ) 或者 GSM ( Global System of Mobile communication, 全球移动通讯系统 ) 等等。 LTE为 4G网络， UMTS为 3G网络， GSM为 2G网络， 所以， LTE 的制式比 UMTS的制式高级， 而 UMTS的制式比 GSM的制式要高级。
如果供流基站可以同时配置使用多个制式， 则数据分流方法与上一实 施方式完全相同。 而且， 也可以同时采用频分模式、 时分模式或者两者的 混合模式。
如果供流基站在同一时间只能采用一种制式， 则在数据分流前， 必须 调整供流基站的制式。 原因在于， 如果第一耗流基站为 GSM制式， 而供流 基站为 LTE 制式， 而位于分流区与第一耗流基站进行通信的用户设备为 GSM制式， 则低级制式的用户设备无法对高级制式的供流基站进行测量， 所以， GSM制式的用户设备无法发现 LTE制式的供流基站。 而且， 在供流 基站在同一时间只能采用一种制式时， 必须使第一耗流基站和供流基站处 于相同的制式， 否则， 无法利用供流基站进行分流。
因此， 如果第一耗流基站的制式比供流基站的制式高级， 并且分流区 内与第一耗流基站通信的用户终端的数量超过第三门限， 则将供流基站的 制式调高至第一耗流基站的制式， 如果用户终端的数量不超过第三门限， 则没必要调高至第一耗流基站的制式， 因为即使调高了供流基站的制式， 分流的作用也不明显； 如果第一耗流基站的制式比供流基站的制式低级， 则直接将供流基站的制式调低至第一耗流基站的制式； 如果第一耗流基站 的制式与供流基站的制式同级， 则不作任何调整。
可以理解， 供流基站在同一时刻只能采用一种制式， 所以， 给不同的 耗流基站进行分流时只能采用时分模式。
参阅图 4, 图 4是本申请数据分流方法再一实施方式的流程图。 本实施 方式的包括如下步骤：
S401 : 第一耗流基站在空口负载超过第一门限时向网络设备发送第一 分流请求。
第二耗流基站利用供流基站的分流资源进行分流时， 如果第一耗流基 站的空口负载超过第一门限时， 认为第一耗流基站已经过载， 需要进行分 流。 于是， 第一耗流基站向网络设备发送第一分流请求。 其中， 第一分流 请求中包含了第一耗流基站所请求的供流基站的分流资源数量。 一般地， 第一耗流基站的空口负载超过第一门限的数量等于所请求的供流基站的分 流资源数量。
S402: 第一耗流基站接收网络设备所发送的分配给第一耗流基站的分 流资源数量。
网络设备在接收到第一耗流基站所发送的第一分流请求后， 从第一分 流请求中获取第一耗流基站所请求的供流基站的分流资源数量。 网络设备 根据第一耗流基站所请求的供流基站的分流资源数量和第二耗流基站可让 出的所占据的供流基站的分流资源数量确定分配给第一耗流基站的分流资 源数量。 如果第二耗流基站让出的分流资源使得供流基站具有的分流资源 大于或等于第一耗流基站所请求的分流资源， 则将等于第一耗流基站所请 求的数量的分流资源分配给第一耗流基站； 如果第二耗流基站让出的分流 资源使得供流基站具有的分流资源小于第一耗流基站所请求的分流资源， 则将供流基站具有的分流资源分配给第一耗流基站。
第一耗流基站接收网络设备所发送的分配给第一耗流基站的分流资源 数量。
S403： 第一耗流基站利用分配第一耗流基站的分流资源， 对位于分流 区内、 空口负载超过第二门限、 并且总占据分流资源数量不超过分配给第 一耗流基站的分流资源数量的用户设备进行分流。
在第一耗流基站获得供流基站的分流资源后， 第一耗流基站利用分配 第一耗流基站的分流资源， 对位于分流区内、 空口负载超过第二门限、 并 且总占据分流资源数量不超过分配给第一耗流基站的分流资源数量的用户 设备进行分流， 其中， 分流区为供流基站所覆盖小区、 第一耗流基站所覆 盖小区、 第二耗流基站所覆盖小区的重叠区域。 即， 要将原来属于第一耗 流基站的用户设备分流到供流基站必须满足三个条件。 （ 1 )用户设备必须 位于分流区内。 （2 )位于分流区内的用户设备的空口负载量超过第二门限。 否则， 将空口负载不超过第二门限的用户设备也分流到供流基站并不能明 显地减少第一耗流基站的负载。 （3 )分流到供流基站的多个用户设备所占 据的总分流资源数量不能超过分配给第一耗流基站的分流资源数量。 第一 耗流基站将满足上述条件的用户设备利用分流资源分流到供流基站。 为了 保证通信质量， 也可以对用户设备的业务类型进行判断， 如果是视频业务 或语音业务等， 则不适宜进行分流， 以防止影响视频或语音的流畅。
其中， 网络设备可以是供流基站、 第二耗流基站或者网络控制器。 并 且， 分流的方式可以采用频分模式、 时分模式或者两者的混合模式。
在第一耗流基站成功地获得供流基站的资源进行分流后， 如果接收到 第三耗流基站所发送的第二分流请求， 第一耗流基站根据历史时间段在分 流资源中物理资源块使用量， 确定可让出的分配给所述第三耗流基站的分 流资源数量， 使得第三耗流基站可利用第一耗流基所让出的分流资源进行 分流。
参阅图 5 , 图 5是本申请网络设备一实施方式的结构示意图。 本实施方 式的网络设备包括： 接收模块 510、 获取模块 520以及确定模块 530。
接收模块 510用于接收第一耗流基站在空口负载超过第一门限时所发 送的分流请求。 比如， 第二耗流基站利用供流基站的分流资源进行分流时， 如果第一耗流基站的空口负载超过第一门限时， 认为第一耗流基站已经过 载， 需要进行分流。 于是， 第一耗流基站向供流基站发送分流请求。 接收 模块 510接收第一耗流基站在空口负载超过第一门限时所发送的分流请求。 其中， 分流请求中包含了第一耗流基站所请求的供流基站的分流资源数量。 一般地， 第一耗流基站的空口负载超过第一门限的数量等于所请求的供流 基站的分流资源数量。 接收模块 510将分流请求向获取模块 520发送。
获取模块 520用于接收分流请求， 从分流请求中获取第一耗流基站所 请求的供流基站的分流资源数量。 比如， 供流基站在接收到第一耗流基站 所发送的分流请求后， 获取模块 520从分流请求中获取第一耗流基站所请 求的供流基站的分流资源数量。 获取模块 520将所请求的供流基站的分流 资源数量向确定模块 530发送。 确定模块 530用于接收所请求的供流基站的分流资源数量， 根据第一 耗流基站所请求的供流基站的分流资源数量和第二耗流基站可让出的供流 基站的分流资源数量确定分配给第一耗流基站的分流资源数量， 以供第一 耗流基站利用分配第一耗流基站的分流资源， 对位于分流区内、 空口负载 超过第二门限、 并且总占据分流资源数量不超过分配给第一耗流基站的分 流资源数量的用户设备进行分流； 分流区为供流基站所覆盖小区、 第一耗 流基站所覆盖小区、 第二耗流基站所覆盖小区的重叠区域。 比如， 在接收 到分流请求后， 可以与第二耗流基站进行协商， 确定模块 530根据第二耗 流基站历史时间段的物理资源块使用量， 确定第二耗流基站可让出的供流 基站的分流资源数量。 确定模块 530根据第一耗流基站所请求的供流基站 的分流资源数量和第二耗流基站可让出的所占据的供流基站的分流资源数 量确定分配给第一耗流基站的分流资源数量。 如果第二耗流基站让出的分 流资源使得供流基站具有的分流资源大于或等于第一耗流基站所请求的分 流资源， 则将等于第一耗流基站所请求的数量的分流资源分配给第一耗流 基站； 如果第二耗流基站让出的分流资源使得供流基站具有的分流资源小 于第一耗流基站所请求的分流资源， 则将供流基站具有的分流资源分配给 第一耗流基站。
在第一耗流基站获得供流基站的分流资源后， 第一耗流基站利用分配 第一耗流基站的分流资源， 对位于分流区内、 空口负载超过第二门限、 并 且总占据分流资源数量不超过分配给第一耗流基站的分流资源数量的用户 设备进行分流， 其中， 分流区为供流基站所覆盖小区、 第一耗流基站所覆 盖小区、 第二耗流基站所覆盖小区的重叠区域。 即， 要将原来属于第一耗 流基站的用户设备分流到供流基站必须满足三个条件。 （ 1 )用户设备必须 位于分流区内。 （2 )位于分流区内的用户设备的空口负载量超过第二门限。 否则， 将空口负载不超过第二门限的用户设备也分流到供流基站并不能明 显地减少第一耗流基站的负载。 （3 )分流到供流基站的多个用户设备所占 据的总分流资源数量不能超过分配给第一耗流基站的分流资源数量。 第一 耗流基站将满足上述条件的用户设备利用分流资源分流到供流基站。 为了 保证通信质量， 也可以对用户设备的业务类型进行判断， 如果是视频业务 或语音业务等， 则不适宜进行分流， 以防止影响视频或语音的流畅。 可以理解， 上述网络设备可以是供流基站， 第二耗流基站， 或分别与 第一耗流基站、 供流基站或第二耗流基站连接的网络控制器。 特别地， 参 阅图 3 ,如果网络的情况较为复杂时，采用网络控制器更能提高分流的效果。
并且， 分流的方式可以采用频分模式、 时分模式或者两者的混合模式。 参阅图 6, 图 6是本申请网络设备另一实施方式的结构示意图。 本实施 方式的网络设备与上一实施方式的不同之处在于， 还包括调整模块 600。
调整模块 600用于在第一耗流基站的制式比供流基站的制式高级， 并 且分流区内与第一耗流基站通信的用户终端的数量超过第三门限时， 调整 模块 600将供流基站的制式调高至第一耗流基站的制式； 在第一耗流基站 的制式比供流基站的制式低级时， 调整模块 600将供流基站的制式调低至 第一耗流基站的制式； 在第一耗流基站的制式与供流基站的制式同级时， 调整模块 600不作任何调整。 比如， 如果供流基站在同一时间只能采用一 种制式， 则在数据分流前， 必须通过调整模块 600调整供流基站的制式。 原因在于， 如果第一耗流基站为 GSM制式， 而供流基站为 LTE制式， 而 位于分流区与第一耗流基站进行通信的用户设备为 GSM制式，则低级制式 的用户设备无法对高级制式的供流基站进行测量， 所以， GSM制式的用户 设备无法发现 LTE制式的供流基站。 而且， 在供流基站在同一时间只能采 用一种制式时， 必须使第一耗流基站和供流基站处于相同的制式， 否则， 无法利用供流基站进行分流。 因此， 在第一耗流基站的制式比供流基站的 制式高级， 并且分流区内与第一耗流基站通信的用户终端的数量超过第三 门限时， 调整模块 600将供流基站的制式调高至第一耗流基站的制式， 在 用户终端的数量不超过第三门限时， 则没必要调高至第一耗流基站的制式， 因为即使调高了供流基站的制式， 分流的作用也不明显； 在第一耗流基站 的制式比供流基站的制式低级时， 调整模块 600直接将供流基站的制式调 低至第一耗流基站的制式； 在第一耗流基站的制式与供流基站的制式同级 时， 则不作任何调整。
可以理解， 供流基站在同一时刻只能采用一种制式， 所以， 给不同的 耗流基站进行分流时只能采用时分模式。

接收器 910用于接收第一耗流基站在空口负载超过第一门限时所发送 的分流请求。 比如， 第二耗流基站利用供流基站的分流资源进行分流时， 如果第一耗流基站的空口负载超过第一门限时， 认为第一耗流基站已经过 载， 需要进行分流。 于是， 第一耗流基站向供流基站发送分流请求。 接收 器 910接收第一耗流基站在空口负载超过第一门限时所发送的分流请求。 其中， 分流请求中包含了第一耗流基站所请求的供流基站的分流资源数量。 一般地， 第一耗流基站的空口负载超过第一门限的数量等于所请求的供流 基站的分流资源数量。 接收器 910将分流请求向处理器 920发送。

发送器 1010用于在空口负载超过第一门限时向网络设备发送第一分流 请求。 比如， 第二耗流基站利用供流基站的分流资源进行分流时， 如果第 一耗流基站的空口负载超过第一门限时， 认为第一耗流基站已经过载， 需 要进行分流。 于是， 发送器 1010向网络设备发送第一分流请求。 其中， 第 一分流请求中包含了第一耗流基站所请求的供流基站的分流资源数量。 一 般地， 第一耗流基站的空口负载超过第一门限的数量等于所请求的供流基 站的分流资源数量。
接收器 1020用于接收网络设备所发送的分配给第一耗流基站的分流资 源数量， 其中， 分配给第一耗流基站的分流资源数量是网络设备根据从第 一分流请求中获取的第一耗流基站所请求的供流基站的分流资源数量和第 二耗流基站可让出的所占据的供流基站的分流资源数量所确定的。 比如， 网络设备在接收到第一耗流基站所发送的第一分流请求后， 从第一分流请 求中获取第一耗流基站所请求的供流基站的分流资源数量。 网络设备根据 第一耗流基站所请求的供流基站的分流资源数量和第二耗流基站可让出的 所占据的供流基站的分流资源数量确定分配给第一耗流基站的分流资源数 量。 如果第二耗流基站让出的分流资源使得供流基站具有的分流资源大于 或等于第一耗流基站所请求的分流资源， 则将等于第一耗流基站所请求的 数量的分流资源分配给第一耗流基站； 如果第二耗流基站让出的分流资源 使得供流基站具有的分流资源小于第一耗流基站所请求的分流资源， 则将 供流基站具有的分流资源分配给第一耗流基站。 接收器 1020接收网络设备 所发送的分配给第一耗流基站的分流资源数量。 接收器 1020将分配给第一 耗流基站的分流资源数量向处理器 1030发送。

其中， 网络设备可以是供流基站、 第二耗流基站或者网络控制器。 并 且， 分流的方式可以采用频分模式、 时分模式或者两者的混合模式。
所述处理器 1030还用于在第一耗流基站成功地获得供流基站的资源进 行分流后， 如果接收到第三耗流基站所发送的第二分流请求， 根据历史时 间段在分流资源中物理资源块使用量， 确定可让出的分配给所述第三耗流 基站的分流资源数量， 使得第三耗流基站可利用第一耗流基所让出的分流 资源进行分流。
