为了更清楚地说明本发明实施例中的技术方案, 下面将对实施例描述中所 需要使用的附图作筒单地介绍, 显而易见地, 下面描述中的附图仅仅是本发明 的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下, 还可以根据这些附图获得其他的附图。

为使本发明的目的、 技术方案和优点更加清楚, 下面将结合附图对本发明 实施方式作进一步地详细描述。 异构网络可以表现为在同一地理区域中共用站址或小区叠加覆盖的多种 无线接入制式的网络; 或者, 异构网络也可以表现为在同一地理区域中小区叠 加覆盖的同一无线接入技术下的多种基站形态组成的网络。 例如, 在同一地理 区域中可以叠加部署全球移动通信系统(Global System of Mobile communication, GSM )、通用移动通信系统 (Universal Mobile Telecommunications System, UMTS )和长期演进( Long Term Evolution, LTE ) 系统等不同无线接 入技术(筒称制式)网络中的至少两者,使得该地理区域形成异构网络; 再如, 在同一地理区域中可以叠加部署 LTE宏蜂窝小区、 LTE微蜂窝小区、 LTE微微 蜂窝小区等不同基站形态的网络, 使得在该地理区域范围内形成异构网络。 在 本发明实施例中, 术语 "网络" 和 "系统" 可以相互替换。
当异构网络投入运营时,组成异构网络的各成员系统的负载状态有着各自 的统计规律。 例如, 对于某个商业写字楼区域, 组成该商业写字楼区域的异构 网络的成员系统包括 GSM、 UMTS和 LTE等不同制式下的小区。 其中, 提供 传统话音业务的 GSM小区在每天的上午 9: 00至 11: 00以及下午 2: 00至 4: 00形成业务负载的高峰期, 而在其他时间段处于业务负载的非高峰期;提供中 低速数据业务的 UMTS小区在每天的 10: 00至 12: 00以及下午 3: 00至 6: 00形成业务负载的高峰期, 而在其他时间段处于业务负载的非高峰期;提供高 速数据业务的 LTE小区在下午的 6: 00至 8: 00形成业务负载的高峰期, 而在 其他时间段处于业务负载的非高峰期。
因此, 当异构网络中各成员系统的小区形成业务负载高峰期的时间段都相 互错开时, 可以将异构网络中处于业务负载非高峰期的成员系统小区的注册载 频中的部分载频共享给处于业务高峰期的其他成员系统的小区使用,从而可以 提高异构网络中频谱的整体使用效率。 其中, 成员系统小区的注册载频可以是 运营商在部署该成员系统时, 为该成员系统小区分配的工作频段。
图 1为本发明实施例提供的一种配置载频的方法的示意图。 如图 1所示, 本发明实施例可以包括:
步骤 101: 若第一小区的负载低于第一负载门限, 且第二小区的负载高于 第二负载门限, 则根据第一负载门限, 在第一小区的注册载频中确定通用载频 的位置; 其中, 第一小区的网络制式为 LTE系统, 第二小区的网络制式为在同 一地理区域部署的异构网络;
步骤 102: 发送该通用载频的寻址信息至第一小区所属的第一基站, 以禁 止第一基站使用该通用载频;
步骤 103: 发送该通用载频的寻址信息至第二小区所属的第二基站, 以允 许第二基站使用该通用载频。
其中, 该通用载频的寻址信息用于向第一基站以及第二基站指示该通用载 频的位置。第一小区的网络制式可以为 LTE系统,第二小区的网络制式可以为 GSM或 UMTS;或者,若第一小区为 LTE宏峰窝小区,第二小区也可以为 LTE 微蜂窝小区或 LTE微微蜂窝小区。步骤 102和步骤 103的执行顺序可以不限定 先后顺序, 可并行执行步骤 102和步骤 103; 或者, 也可先执行步骤 102, 再 执行步骤 103; 或者, 还可先执行步骤 103, 再执行步骤 102。
采用本发明实施例提供的配置载频的方法, 可以根据第一小区和第二小区 的负载情况自动触发载频配置过程; 并且, 根据第一负载门限和第一小区的注 册载频大小获取通用载频的大小, 可以保证选取的通用载频大小能够适配异构 网络中小区负载变化的实际需求。此外, 由于 LTE系统的物理层设计保证了灵 活的频谱带宽配置,选择 LTE系统作为确定通用载频位置的第一小区(源成员 系统), 有利于避免载频配置过程对第一小区的正常运行造成影响, 从而可以 提高载频配置过程的可靠性。 为了更清楚地介绍图 1所示实施例提供的载频配置方法,下面结合图 2-1、 图 2-2进行示意性说明。 图 2-1为本发明实施例提供的一种配置载频的方法的 应用场景示意图。 参见图 2-1所示, 该应用场景可包括载频配置实体、 第一基 站和第二基站。 其中, 载频配置实体用于为第一基站和第二基站配置载频。 例 如, 该载频配置实体可以对第一小区和第二小区进行监控, 当监控出第一小区 的负载低于第一负载门限, 且第二小区的负载高于第二负载门限时, 则触发如 下图 2-2所示实施例提供的载频配置的过程。
图 2-2 为本发明实施例提供的一种配置载频方法的流程示意图。 参见图 2-2, 该方法包括:
步骤 201: 载频配置实体对第一小区和第二小区进行监控, 如果监控出第 一小区的负载低于第一负载门限, 且第二小区的负载高于第二负载门限, 则执 行步骤 202; 不同类型的基站起汇聚控制作用的网元设备, 或者是和异构网络中的基站相连 的授权可信的应用服务器, 在此不作限定。
如前所述, 异构网络中各成员系统的负载状态有着各自的统计规律, 各小 区的业务负载高峰期可能会相互错开, 因此, 可以将处于业务负载非高峰期的 成员系统小区的注册载频中的部分载频,提供给处于业务高峰期的其他成员系 统的小区使用, 以提高异构网络中频谱的整体使用效率。
具体地, 可以根据第一小区和第二小区的负载状态的统计规律, 分别设置 第一负载门限和第二负载门限。 当第一小区的负载低于第一负载门限时, 说明 第一小区处于业务负载非高峰期, 即第一小区可以提供部分载频供其他小区使 用; 类似地, 当第二小区的负载高于第二负载门限时, 说明第二小区处于业务 负载高峰期, 需要其他小区提供部分载频。 当同时出现第一小区的负载低于第 一负载门限,且第二小区的负载高于第二负载门限,则可以触发载频配置过程, 将第一小区的注册载频中的部分载频共享给第二小区使用。 需要说明的是, 对 于第一小区的负载等于第一负载门限或第二小区的负载等于第二负载门限的 情况, 可认为是临界情形。 此时, 既可以认为第一小区或第二小区已进入负载 高峰期, 也可认为尚未进入负载高峰期。
其中, 第一负载门限和第二负载门限的具体取值可以由技术人员根据经验 预先设定, 或参考异构网络的负载状态的统计规律进行动态调整; 或者, 也可 以由载频配置实体参考异构网络的负载状态的统计规律进行定期更新, 本发明 实施例不作具体限定。
步骤 202: 载频配置实体根据第一负载门限, 在第一小区的注册载频中确 定出通用载频的位置;
具体地, 载频配置实体可以根据第一负载门限和第一小区的注册载频的大 小, 确定通用载频的大小; 根据第一小区的注册载频的类型和该通用载频的大 小, 在第一小区注册载频中确定该通用载频的位置。 例如, H殳第一小区的第 一负载门限被设置为 30% (即最多可提供 70%的注册载频作为通用载频), 第 一小区的的注册载频大小为 10MHz,则根据第一负载门限和第一小区的的注册 载频大小的取值, 可计算出第一小区能提供的通用载频大小为 7MHz, 从而避 免划分出过多的载频资源而对第一小区内传输的业务产生负面影响。 其中, 当 第一小区的网络制式为 LTE系统时, 由于 LTE小区的载频调度分配单位是物 理资源块 (Physical Resource Block, PRB), 能提供的通用载频的大小是一个物理 资源块的整数倍。 可选地, 载频配置实体根据第一小区的注册载频的类型和该通用载频的大 小确定通用载频的位置的操作, 可以包括:
若第一小区的注册载频的类型为非新载波类型, 则在第一小区的注册载频 中, 选择物理下行控制信道(Physical Downlink Control Channel, PDCCH )所 占用载频之外的其他载频; 根据该通用载频的大小, 在选择的其他载频中确定 通用载频的位置; 或者,
若第一小区的注册载频的类型为新载波类型, 则在第一小区的全部注册载 频中, 根据该通用载频的大小确定通用载频的位置; 其中, 第一小区的全部注 册载频包括第一'』、区的增强的物理下行控制信道( enhanced Physical Downlink Control Channel, E-PDCCH )所占用的载频。
PDCCH用于传输第一小区所属的第一基站与第一小区内的 UE之间的控 制信令, 如果在 PDCCH占用的载频上划分通用载频, 则可能影响第一基站与 UE之间的控制信令的传输。 而在本发明实施例中, 通用载频在第一小区的注 册载频包括的除 PDCCH占用的载频以外的其他载频中确定, 可以保证不影响 第一基站与 UE之间的控制面信令的传输,而集中适应用户面数据的统计波动。 当第一小区的载频类型为新载波类型时, 由于第一基站与 UE之间的信令和数 据传输时分复用 E-PDCCH信道,则第一小区的注册载频中可以包括 E-PDCCH 占用的载频, 从而可以进一步提高系统的频谱利用率。
步骤 203: 载频配置实体发送该通用载频的寻址信息给第一小区所属的第 一基站和第二小区所属的第二基站; 其中, 该通用载频的寻址信息用于向第一 基站以及第二基站指示该通用载频的位置;
例如, 载频配置实体可以发送载频配置消息给第一小区所属的第一基站和 第二小区所属的第二基站,该载频配置消息携带该通用载频的寻址信息。其中, 该通用载频的寻址信息具体可以为通用载频的起始频点和结束频点; 或者, 也 可以为通用载频的起始频点和该通用载频所占用的带宽。 可选地, 图 2-2所示实施例提供的配置载频的方法还可包括以下步骤: 步骤 204: 第一基站接收该通用载频的寻址信息, 根据该通用载频的寻址 信息确定该通用载频的位置, 以停止使用该通用载频;
具体地, 第一基站接收该通用载频的寻址信息, 根据该通用载频的寻址信 息确定出该通用载频的位置, 禁止将该通用载频分配给接入第一小区的 UE, 以停止使用该通用载频。
例如, 第一基站可以接收载频配置实体发送的载频配置消息, 从该载频配 置消息中提取通用载频的寻址信息。
其中, 如果通用载频的寻址信息为通用载频的起始频点和结束频点, 则根 据通用载频的起始频点和结束频点,在第一小区的注册载频上确定出通用载频 的起始频点和结束频点, 从而确定出通用载频的位置。
如果通用载频的寻址信息为通用载频的起始频点和带宽, 则根据通用载频 的起始频点, 确定出通用载频在第一小区的注册载频上的起始频点, 根据通用 载频的带宽和通用载频在第一小区的注册载频上的起始频点, 在第一小区的注 册载频上确定出通用载频的位置。
进一步地, 第一基站还可以存储该通用载频的位置。 步骤 205: 第二基站接收该通用载频的寻址信息, 根据该通用载频的寻址 信息, 在第一小区的的注册载频上确定出通用载频的位置;
例如, 第二基站可以接收载频配置实体发送的载频配置消息, 从该载频配 置消息中提取通用载频的寻址信息。
进一步地, 第二基站还可以存储该通用载频的位置。
其中, 第二基站根据该通用载频的寻址信息、 在第一小区的注册载频上确 定出通用载频的位置的操作, 与第一基站根据该通用载频的寻址信息、 在第一 小区的注册载频上确定出通用载频的位置的操作相同, 在此不再详细说明。 步骤 206: 第二基站根据第二小区支持工作载频大小划分通用载频, 将划 分的通用载频分配给接入第二小区的 UE;
其中, 如果第二小区的网络制式为 GSM, 则第二基站可以将通用载频分 割成一个或多个大小为 200kHz的工作频带, 将划分的工作频带分配给接入第 二小区的 UE; 如果第二小区的网络制式为 S-UMTS, 则第二基站可以将通用 载频分割成一个或多个大小为 625kHz的工作频带, 将划分的工作频带分配给 接入第二小区的 UE; 如果第二小区为 LTE微蜂窝小区或 LTE微微蜂窝小区, 则第二基站将通用载频分割成一个或多个大小为 1.4Mhz的工作频带, 将划分 的工作频带分配给接入第二小区的 UE。 可选地, 载频配置实体还可以继续对第一小区的负载和第二小区的负载进 行监控,如果监控出第一小区的负载高于第三负载门限或第二小区的负载低于 第四负载门限,则执行如下步骤 207至 210来收回分配给第二小区的通用载频。
其中, 该第三负载门限和第四负载门限的选取, 可以参考上述第一负载门 限和第二负载门限的选取方法。 筒便地, 该第三负载门限可以等于上述第一负 载门限,该第四负载门限可以等于上述第二负载门限。或者,为了防止类似 "乒 乓效应" 的情况出现, 该第三负载门限可以与上述第一负载门限间相差一特定 的偏置量, 该第四负载门限可以与上述第二负载门限间相差一特定的偏置量, 此处并不限定具体偏置量的取值。
步骤 207: 载频配置实体对第一小区和第二小区进行监控, 如果监控出第 一小区的负载高于第三负载门限或第二小区的负载低于第四负载门限时,执行 步骤 208;
步骤 208: 载频配置实体发送载第一指示消息给第一基站和第二基站; 步骤 209: 第二基站接收第一指示消息, 根据第一指示消息的指示, 停止 使用该通用载频;
具体地, 第二基站接收第一指示消息, 根据第一指示消息的指示, 获取自 身存储的该通用载频的位置,停止将确定出的通用载频分配给接入第二小区的 UE, 以禁止使用该通用载频。
步骤 210: 第一基站接收第一指示消息, 根据第一指示消息的指示, 使用 该通用载频。
具体地, 第一基站接收第一指示消息, 根据第一指示消息的指示, 获取自 身存储的通用载频的位置,根据第一小区支持的工作频带的大小划分确定出的 通用载频, 将划分的通用载频分配给接入第一小区的 UE, 以使用该通用载频。
采用该可选实施例提供的技术方案, 当第一小区的负载高于第三负载门限 或第二小区的负载低于第四负载门限时, 可以及时收回共享给第二小区使用的 通用载频, 避免对第一小区的正常工作造成影响。
此外, 可选地, 若第一基站和第二基站中已存储有通用载频的位置, 载频 配置实体再次监控出第一小区的负载低于第一负载门限, 第二小区的负载再次 高于第二负载门限时, 还可以发送第二指示消息给第一基站, 以禁止第一基站 使用该通用载频; 发送第二指示消息给第二基站, 以允许第二基站使用该通用 载频。

第二基站接收第二指示消息, 根据第二指示消息的指示, 获取已存储的通 用载频的位置, 将该通用载频分配给接入第二小区的 UE, 以实现使用该通用 载频。
采用该可选实施例提供的技术方案, 当第一基站和第二基站中已存储有通 用载频的位置, 载频配置实体可以只需发送第二指示消息即可实现载频配置过 程, 从而避免重复确定通用载频的位置, 筒化载频配置过程。 图 3为本发明实施例提供的一种配置载频的装置 30的结构示意图, 该装 置 30可以用于图 1所示的实施例提供的配置载频的方法, 可以为图 2-1所示 的实施例的载频配置实体, 可以用于图 2-2所示的实施例提供的配置载频的方 法。 此处未详尽说明的内容, 可以参考图 1、 图 2-1、 图 2-2所示实施例中的介 绍。 参见图 3 , 该装置 30包括:
处理单元 301 , 用于若第一小区的负载低于第一负载门限, 且第二小区的 负载高于第二负载门限, 则根据所述第一负载门限, 在所述第一小区的注册载 频中确定通用载频的位置; 其中, 所述第一小区的网络制式为 LTE系统, 所述 第二小区的网络制式为在同一地理区域部署的异构网络;
发送单元 302, 用于发送所述通用载频的寻址信息至所述第一小区所属的 第一基站, 以禁止所述第一基站使用所述通用载频; 发送所述通用载频的寻址 信息至所述第二小区所属的第二基站, 以允许所述第二基站使用所述通用载 频;
其中, 所述通用载频的寻址信息用于向所述第一基站以及所述第二基站指 示所述通用载频的位置。 该通用载频的寻址信息具体可以为通用载频的起始频 点和结束频点; 或者, 也可以为通用载频的起始频点和该通用载频所占用的带 宽。
其中, 采用本发明实施例提供的配置载频的装置, 可以根据第一小区和第 二小区的负载情况自动触发载频配置过程; 此外, 由于 LTE系统的物理层设计 保证了灵活的频谱带宽配置,选择 LTE系统作为确定通用载频位置的第一小区
(源成员系统), 有利于避免载频配置过程对第一小区的正常运行造成影响, 从而可以提高载频配置过程的可靠性。
其中, 异构网络中各成员系统的负载状态有着各自的统计规律, 各小区的 业务负载高峰期可能会相互错开, 因此, 可以将处于业务负载非高峰期的成员 系统小区的注册载频中的部分载频,提供给处于业务高峰期的其他成员系统的 小区使用, 以提高异构网络中频谱的整体使用效率。
可选地, 所述处理单元 301 , 具体用于: 根据所述第一负载门限, 以及所 述第一小区的注册载频的大小, 确定所述通用载频的大小; 根据所述通用载频 的大小, 以及所述第一小区的注册载频的类型, 确定所述通用载频的位置。
其中, 处理单元 301根据第一负载门限和第一小区的注册载频大小获取通 用载频的大小, 可以保证选取的通用载频大小能够适配异构网络中小区负载变 化的实际需求。
可选地, 所述处理单元 301 , 具体用于: 若所述第一小区的注册载频的类 型为非新载波类型, 则在所述第一小区的注册载频中, 选择 PDCCH所占用载 频之外的其他载频; 根据所述通用载频的大小, 在所述选择的其他载频中确定 所述通用载频的位置; 若所述第一小区的注册载频的类型为新载波类型, 则在 所述第一小区的全部注册载频中,根据所述通用载频的大小确定所述通用载频 的位置; 其中, 所述第一小区的全部注册载频包括所述第一小区的 E-PDCCH 所占用的载频。
其中, PDCCH用于传输第一小区所属的第一基站与第一小区内的 UE之 间的控制信令, 如果在 PDCCH占用的载频上划分通用载频, 则可能影响第一 基站与 UE之间的控制信令的传输。 而在本发明实施例中, 通用载频在第一小 区的注册载频包括的除 PDCCH占用的载频以外的其他载频中确定, 可以保证 不影响第一基站与 UE之间的控制面信令的传输, 而集中适应用户面数据的统 计波动。 当第一小区的载频类型为新载波类型时, 由于第一基站与 UE之间的 信令和数据传输时分复用 E-PDCCH信道, 则第一小区的注册载频中可以包括 E-PDCCH占用的载频, 从而可以进一步提高系统的频谱利用率。
进一步地, 所述处理单元 301 , 还可用于对第一小区的负载和第二小区的 负载进行监控。
进一步地, 所述发送单元 302, 还可用于若所述第一小区的负载高于第三 负载门限, 或所述第二小区的负载低于第四负载门限, 则发送第一指示消息至 所述第一基站, 以允许所述第一基站使用所述通用载频, 发送所述第一指示消 息至所述第二基站, 以禁止所述第二基站使用所述通用载频。
其中, 处理单元 301和发送单元 302当第一小区的负载高于第三负载门限 或第二小区的负载低于第四负载门限时, 可以及时收回共享给第二小区使用的 通用载频, 避免对第一小区的正常工作造成影响。
进一步地, 所述发送单元 302, 还可用于若所述第一小区的负载再次低于 所述第一负载门限, 且所述第二小区的负载再次高于所述第二负载门限, 则发 送第二指示消息至所述第一基站, 以禁止所述第一基站使用所述通用载频, 发 送所述第二指示消息至所述第二基站, 以允许所述第二基站使用所述通用载 频。
其中, 当第一基站和第二基站中已存储有通用载频的位置, 发送单元 302 可以只需发送第二指示消息即可实现载频配置过程,从而避免处理单元 301重 复确定通用载频的位置, 筒化载频配置过程。
所述装置为载频配置实体, 所述载频配置实体用于为所述第一基站和所述 第二基站配置载频。 在实现过程中, 该处理单元 301具体可以为处理器, 该发 送单元 302 具体可以为发送器。 其中, 处理器可以为中央处理器 (Central Processing Unit, CPU )或单片机等。 参见图 4, 本发明实施例提供了一种配置载频的系统 40, 包括:
载频配置实体 401、 第一基站 402和第二基站 403;
所述载频配置实体 401 , 用于若第一小区的负载低于第一负载门限, 且第 二小区的负载高于第二负载门限, 则根据所述第一负载门限, 在所述第一小区 的注册载频中确定通用载频的位置; 其中, 所述第一小区的网络制式为长期演 进 LTE系统,所述第二小区的网络制式为在同一地理区域部署的异构网络;发 送所述通用载频的寻址信息至所述第一小区所属的第一基站; 发送所述通用载 频的寻址信息至所述第二小区所属的第二基站; 其中, 所述通用载频的寻址信 息用于向所述第一基站以及所述第二基站指示所述通用载频的位置;

该载频配置实体 401可以为图 3所示实施例提供的装置 30,本发明实施例 提供的配置载频的系统 40可以用于实现图 1、图 2-2所示实施例提供的配置载 频的方法, 详细内容可参考上述实施例中的介绍, 此处不再赘述。
采用本发明实施例提供的配置载频的系统, 载频配置实体可以根据第一小 区和第二小区的负载情况自动触发载频配置过程; 并且, 根据第一负载门限和 在第一小区的注册载频上确定通用载频的位置, 可以保证确定的通用载频能够 适配异构网络中小区负载变化的实际需求。此外, 由于 LTE系统的物理层设计 保证了灵活的频谱带宽配置,选择 LTE系统作为确定通用载频位置的第一小区 (源成员系统), 有利于避免载频配置过程对第一小区的正常运行造成影响, 从而可以提高载频配置过程的可靠性。 另外, 异构网络中各成员系统的负载状 态有着各自的统计规律, 各小区的业务负载高峰期可能会相互错开, 因此, 可 以将处于业务负载非高峰期的第一小区的注册载频中的部分载频,提供给处于 业务高峰期的第二小区使用, 以提高异构网络中频谱的整体使用效率。 图 5为本发明实施例提供的一种配置载频的方法的示意图。 如图 5所示, 本发明实施例可以包括:
步骤 501: 若第一小区的负载低于第一负载门限, 且第二小区的负载高于 第二负载门限, 则第一小区所属的第一基站根据第一负载门限, 在第一小区的 注册载频中确定通用载频的位置, 并停止使用该通用载频; 其中, 第一小区的 网络制式为 LTE 系统, 第二小区的网络制式为在同一地理区域部署的异构网 络;
步骤 502: 发送该通用载频的寻址信息至第二小区所属的第二基站, 以允 许第二基站使用该通用载频; 其中, 该通用载频的寻址信息用于向第二基站指 示该通用载频的位置。
采用本发明实施例提供的配置载频的方法, 第一基站可以根据第一小区和 第二小区的负载情况自动触发载频配置过程; 并且, 根据第一负载门限, 在第 一小区的注册载频上确定通用载频的位置, 可以保证确定的通用载频能够适配 异构网络中小区负载变化的实际需求。此外, 由于 LTE系统的物理层设计保证 了灵活的频谱带宽配置,选择 LTE系统作为确定通用载频位置的第一小区(源 成员系统), 有利于避免载频配置过程对第一小区的正常运行造成影响, 从而 可以提高载频配置过程的可靠性。 另外, 异构网络中各成员系统的负载状态有 着各自的统计规律, 各小区的业务负载高峰期可能会相互错开, 因此, 可以将 处于业务负载非高峰期的第一小区的注册载频中的部分载频,提供给处于业务 高峰期的第二小区使用, 以提高异构网络中频谱的整体使用效率。 为了更清楚地介绍图 5所示实施例提供的载频配置方法, 下面结合图 6进 行示意性说明。 第一基站可以对第一小区和第二小区进行监控, 当监控出第一 小区的负载低于第一负载门限, 且第二小区的负载高于第二负载门限时, 则触 发如下图 6所示实施例提供的载频配置的过程。
图 6为本发明实施例提供的一种配置载频方法的流程示意图。 参见图 6, 该方法包括: 步骤 601: 第一小区所属的第一基站对第一小区和第二小区进行监控, 如 果监控出第一小区的负载低于预设第一负载门限,且第二小区的负载高于预设 第二负载门限时, 执行步骤 602;
其中, 在本发明实施例中, 第一小区和第二小区是组成该地理区域的异构 网络包括的成员系统。第一小区的网络制式为 LTE系统, 第二小区的网络制式 可以为 UMTS和 GSM等, 且第一小区的网络制式和第二小区的网络制式是两 种不同的网络制式; 或者, 第一小区为 LTE宏蜂窝小区以及第二小区为 LTE 微蜂窝小区。
其中,如前所述,异构网络中各成员系统的负载状态有着各自的统计规律, 各小区的业务负载高峰期可能会相互错开, 因此, 可以将处于业务负载非高峰 期的成员系统小区的注册载频中的部分载频,提供给处于业务高峰期的其他成 员系统的小区使用, 以提高异构网络中频谱的整体使用效率。
具体地, 可以根据第一小区和第二小区的负载状态的统计规律, 分别设置 第一负载门限和第二负载门限。 当第一小区的负载低于第一负载门限时, 说明 第一小区处于业务负载非高峰期, 即第一小区可以提供部分载频供其他小区使 用; 类似地, 当第二小区的负载高于第二负载门限时, 说明第二小区处于业务 负载高峰期, 需要其他小区提供部分载频。 当同时出现第一小区的负载低于第 一负载门限,且第二小区的负载高于第二负载门限,则可以触发载频配置过程, 将第一小区的注册载频中的部分载频共享给第二小区使用。 需要说明的是, 对 于第一小区的负载等于第一负载门限或第二小区的负载等于第二负载门限的 情况, 可认为是临界情形。 此时, 既可以认为第一小区或第二小区已进入负载 高峰期, 也可认为尚未进入负载高峰期。
其中, 第一负载门限和第二负载门限的具体取值可以由技术人员根据经验 预先设定, 或参考异构网络的负载状态的统计规律进行动态调整; 或者, 也可 以由第一基站参考异构网络的负载状态的统计规律进行定期更新, 本发明实施 例不作具体限定。
可选地, 在本发明实施例中, 第二基站可以对第一小区的负载和第二小区 的负载进行监控, 而第一基站可以不对第一小区的负载和第二小区的负载进行 监控。 当第二基站监控出第一小区的负载低于预设第一负载门限以及第二小区 的负载高于预设第二负载门限时, 第二基站发送载频配置请求消息给第一基 站, 第一基站接收该载频配置消息后执行步骤 602。
其中, 在本发明实施例中, 由第一基站来触发配置载频的流程, 从而可以 不需要在网络中部署载频配置实体, 可以节省运营商的运营成本。
步骤 602: 第一基站根据第一负载门限或第二负载门限, 在第一小区的注 册载频中确定出通用载频的位置;
具体地, 第一基站可以根据第一负载门限和第一小区的注册载频的大小, 确定通用载频的大小; ^据第一小区的注册载频的类型和该通用载频的大小, 在第一小区注册载频中确定该通用载频的位置。 例如, H殳第一小区的第一负 载门限被设置为 30% (即最多可提供 70%的注册载频作为通用载频), 第一小 区的的注册载频大小为 10MHz,则根据第一负载门限和第一小区的的注册载频 大小的取值, 可计算出第一小区能提供的通用载频大小为 7MHz, 从而避免划 分出过多的载频资源而对第一小区内传输的业务产生负面影响。
可选地, 第一基站根据第一小区的注册载频的类型和该通用载频的大小, 在第一小区的的注册载频中确定出通用载频的位置的操作, 可以为:
若第一小区的注册载频的类型为非新载波类型, 则在第一小区的注册载频 中, 选择 PDCCH所占用载频之外的其他载频; 根据该通用载频的大小, 在选 择的其他载频中确定通用载频的位置; 若第一小区的注册载频的类型为新载波 类型, 则在第一小区的全部注册载频中, 根据该通用载频的大小确定通用载频 的位置; 其中, 第一小区的全部注册载频包括第一小区的 E-PDCCH所占用的 载频的注册载频。
其中, PDCCH用于传输第一小区所属的第一基站与第一小区内的 UE之 间的控制信令, 如果在 PDCCH占用的载频上划分通用载频, 则可能影响第一 基站与 UE之间的控制信令的传输。 而在本发明实施例中, 通用载频在第一小 区的注册载频包括的除 PDCCH占用的载频以外的其他载频中确定, 可以保证 不影响第一基站与 UE之间的控制面信令的传输, 而集中适应用户面数据的统 计波动。 当第一小区的载频类型为新载波类型时, 由于第一基站与 UE之间的 信令和数据传输时分复用 E-PDCCH信道, 则第一小区的注册载频中可以包括 E-PDCCH占用的载频, 从而可以进一步提高系统的频谱利用率。 进一步地, 第一基站还可以存储该通用载频的位置。
步骤 603: 第一基站停止使用该通用载频, 发送通用载频的寻址信息给第 二小区所属的第二基站;
具体地, 该通用载频的寻址信息可以为通用载频的起始频点和结束频点, 通用载频的起始频点和带宽。 可选地, 图 6所示实施例提供的配置载频的方法还可包括以下步骤: 步骤 604: 第二基站接收该通用载频的寻址信息, 根据该通用载频的寻址 信息, 在第一小区的的注册载频上确定出通用载频的位置;
其中, 如果通用载频的寻址信息为通用载频的起始频点和结束频点, 则第 二基站根据通用载频的起始频点和结束频点, 在第一小区的注册载频上确定出 通用载频的起始频点和结束频点, 从而确定出通用载频的位置;
如果通用载频的寻址信息为通用载频的起始频点和带宽, 则第二基站根据 通用载频的起始频点, 确定出通用载频在第一小区的注册载频上的起始频点, 根据通用载频的带宽和通用载频在第一小区的注册载频上的起始频点, 在第一 小区的注册载频上确定出通用载频的位置;
进一步地, 第二基站还可以存储该通用载频的位置。
步骤 605: 第二基站根据第二小区支持的工作频带的大小, 划分通用载频, 将划分的通用载频分配给接入第二小区的 UE; 可选地, 第一基站还可以继续对第一小区的负载和第二小区的负载进行监 控, 如果监控出第一小区的负载高于第三负载门限或第二小区的负载低于第四 负载门限时, 则执行如下步骤 606至 608来收回分配给第二小区的通用载频。
其中, 该第三负载门限和第四负载门限的选取, 可以参考上述第一负载门 限和第二负载门限的选取方法。 筒便地, 该第三负载门限可以等于上述第一负 载门限,该第四负载门限可以等于上述第二负载门限。或者,为了防止类似 "乒 乓效应" 的情况出现, 该第三负载门限可以与上述第一负载门限间相差一特定 的偏置量, 该第四负载门限可以与上述第二负载门限间相差一特定的偏置量, 此处并不限定具体偏置量的取值。 步骤 606: 第一基站对第一小区和第二小区进行监控, 如果监控出第一小 区的负载高于第三负载门限或第二小区的负载低于第四负载门限时,执行 607; 步骤 607: 第一基站发送第一指示消息给第二基站;
步骤 608: 第二基站接收第一指示消息, 根据第一指示消息的指示, 禁止 使用该通用载频;
具体地, 第二基站接收第一指示消息, 根据第一指示消息的指示, 获取已 存储的通用载频的寻址信息,根据该通用载频的寻址信息在第一小区的注册载 频上确定出通用载频的位置,停止将确定出的通用载频分配给接入第二小区的 UE, 以实现禁止使用该通用载频。
步骤 609: 第一基站使用该通用载频。
具体地, 第一小基站根据该通用载频的寻址信息, 在第一小区的注册载频 上确定出通用载频的位置,根据第一小区支持的工作频带划分确定出的通用载 频, 将划分的通用载频分配给接入第一小区的 UE。
采用该可选实施例提供的技术方案, 当第一小区的负载高于第三负载门限 或第二小区的负载低于第四负载门限时, 可以及时收回共享给第二小区使用的 通用载频, 避免对第一小区的正常工作造成影响。
此外, 可选地, 若第一基站和第二基站中已存储有通用载频的位置, 第一 基站再次监控出第一小区的负载低于第一负载门限, 第二小区的负载再次高于 第二负载门限时,还可以停止使用该通用载频,发送第二指示消息给第二基站, 以允许第二基站使用该通用载频。
第二基站接收第二指示消息, 根据第二指示消息的指示, 获取已存储的通 用载频的位置, 将该通用载频分配给接入第二小区的 UE, 以实现使用该通用 载频。 图 7为本发明实施例提供的一种配置载频的装置 70的结构示意图, 该装 置 70可以用于图 5所示的实施例提供的配置载频的方法, 可以为图 6所示的 实施例的第一基站, 可以用于图 6所示的实施例提供的配置载频的方法。 此处 未详尽说明的内容, 可以参考图 5、 图 6所示实施例中的介绍。 参见图 7, 该 装置 70包括: 处理单元 701 , 用于若第一小区的负载低于第一负载门限, 且第二小区的 负载高于第二负载门限, 则根据所述第一负载门限, 在所述第一小区的注册载 频中确定通用载频的位置, 并停止使用所述通用载频; 其中, 所述第一小区的 网络制式为长期演进 LTE系统 ,所述第二小区的网络制式为在同一地理区域部 署的异构网络;

(源成员系统), 有利于避免载频配置过程对第一小区的正常运行造成影响, 从而可以提高载频配置过程的可靠性。
其中, 异构网络中各成员系统的负载状态有着各自的统计规律, 各小区的 业务负载高峰期可能会相互错开, 因此, 可以将处于业务负载非高峰期的成员 系统小区的注册载频中的部分载频,提供给处于业务高峰期的其他成员系统的 小区使用, 以提高异构网络中频谱的整体使用效率。

其中, PDCCH用于传输第一小区所属的第一基站与第一小区内的 UE之 间的控制信令, 如果在 PDCCH占用的载频上划分通用载频, 则可能影响第一 基站与 UE之间的控制信令的传输。 而在本发明实施例中, 通用载频在第一小 区的注册载频包括的除 PDCCH占用的载频以外的其他载频中确定, 可以保证 不影响第一基站与 UE之间的控制面信令的传输, 而集中适应用户面数据的统 计波动。 当第一小区的载频类型为新载波类型时, 由于第一基站与 UE之间的 信令和数据传输时分复用 E-PDCCH信道, 则第一小区的注册载频中可以包括 E-PDCCH占用的载频, 从而可以进一步提高系统的频谱利用率。
进一步地, 所述处理单元 701 , 还用于若所述第一小区的负载高于第三负 载门限, 或所述第二小区的负载低于预设第四负载门限, 则继续使用所述通用 载频;
