Description

载频控制方法及装置 技术领域 本发明涉及通信领域， 具体而言， 涉及一种载频控制方法及装置。 背景技术 随着移动通信技术，例如，宽带码分多址（Wideband Code Division Multiple Access, 简称为 WCDMA)系统和全球移动通讯系统（Global System of Mobile communication, 简称为 GSM) 的发展， 同一区域由多个无线网络覆盖的情况越来越普遍。 同时由于日 益增长的运营成本以及日益严峻的气候变暖等环境问题， 使得运营商将节能降耗放在 了越来越重要的位置。 为了解决这一问题， 技术人员设计了一些载波关断的方法。 智 能载波关断算法能在网络低负载的时候关掉不需要的载频， 以达到节能目的。 在现有技术中有一种载频时隙的关断方法， 该技术在基站处于负荷下降状态时， 关断广播控制信道 （Broadcast Control Channel, 简称为 BCCH) 收发信机的部分空闲 的业务时隙； 在基站处于负荷增加状态时， 开启 BCCH 收发信机的全部业务时隙。 该 技术减少了基站设备在负荷下降状态下的绝对功耗， 提升了射频模块的效率。 但是， 该技术只有在 GSM通信系统才发生作用， 而对于多个无线网络重叠覆盖 的情况， 例如， 第二代或第三代 （2nd/3rd Generation, 简称为 2/3G) 重叠组网时， 无 法综合考虑 2/3G用户及业务的分布情况， 从而无法做到既保证用户的网络服务质量 (Quality of Server, 简称为 QoS)， 又充分考虑运营商的节能降耗问题。 在现有技术中还提供了一种手段， 使用自组织网络 （Self Organizing Network, 简 称为 SON)对基站的小区是否休眠和 /或唤醒进行判断；当判断结果为小区需要休眠时， SON指示基站休眠小区； 当判断结果为小区需要唤醒时， SON指示基站唤醒小区。 但是， 该方法只能在长期演进 （Long-Term Evolution, 简称为 LTE) 单制式下才 能发挥作用， 同样也无法解决多个无线网络重叠覆盖时的节能降耗问题。 针对相关技术中无法对多个无线网络重叠覆盖区域的载频进行综合控制的问题， 目前尚未提出有效的解决方案。 发明内容 本发明实施例提供了一种载频控制方法及装置， 以至少解决相关技术中无法对多 个无线网络重叠覆盖区域的载频进行综合控制的问题。 根据本发明实施例的一个方面， 提供了一种载频控制方法， 包括： 控制器获取邻 区的负载信息，其中，控制器所在小区与邻区归属不同网络且具有同覆盖或包含关系； 上述控制器根据控制器所在小区与其邻区的负载信息确定需要控制的载频； 上述控制 器根据载频的组网类型控制载频的关断或开启。 优选地， 上述控制器根据载频的组网类型控制载频的关断或开启包括： 上述控制 器为 2G的基站控制器时， 如果需要控制的载频为 3G载频， 基站控制器通过与 3G的 无线网络控制器的接口， 通知无线网络控制器控制载频的关断或开启； 上述控制器为 3G的无线网络控制器时，如果需要控制的载频为 2G载频，无线网络控制器通过与 2G 的基站控制器接口， 通知基站控制器控制载频的关断或开启。 优选地，上述控制器为多模控制器时，上述接口为信息交互接口或标准 Iur-g接口； 上述控制器为单模控制器时， 上述接口为标准 Iur-g接口。 优选地， 基站控制器通知无线网络控制器控制载频的关断或开启包括： 基站控制 器向无线网络控制器发送指示关断或开启载频的请求消息， 无线网络控制器接收到请 求消息后， 根据请求消息的指示关断或开启载频， 向基站控制器返回响应消息； 无线 网络控制器通知基站控制器控制载频的关断或开启包括： 无线网络控制器向基站控制 器发送指示关断或开启载频的请求消息， 基站控制器接收到请求消息后， 根据请求消 息的指示关断或开启载频， 向无线网络控制器返回响应消息。 优选地， 控制器根据邻区的负载信息确定需要控制的载频包括： 在负载的用户数 或小区负荷低于设定的关断门限时， 按照设定的关断优先关系确定需要关断的载频； 在负载的用户数或小区负荷高于设定的开启门限时， 按照设定的开启优先关系确定需 要开启的载频。 优选地， 控制器根据邻区的负载信息确定需要控制的载频之前还包括： 设定的关 断门限或开启门限按照以下参数至少之一设定： 剩余等效用户数、 上行 TCP功率、 下 行 RTWP干扰、 小区上下行负荷、 上下行 CE、 码资源、 剩余传输资源。 优选地， 控制器根据载频的组网类型控制载频的关断包括： 上述控制器在确定需 要关断的载频的指定时间后， 再次对该载频进行关断判决， 若两次判决结果一致， 则 执行载频的关断。 优选地， 控制器根据载频的组网类型控制载频的关断或开启包括： 上述控制器判 断当前时间是否处于控制载频的允许时间段内； 如果是， 上述控制器根据载频的组网 类型控制载频的关断或开启。 根据本发明实施例的另一方面， 提供了一种载频控制装置， 位于控制器中， 该装 置包括： 获取模块， 设置为获取邻区的负载信息， 其中， 上述控制器所在小区与邻区 归属不同网络且具有同覆盖或包含关系； 确定模块， 设置为根据获取模块获取的控制 器所在小区与其邻区的负载信息确定需要控制的载频； 控制模块， 设置为根据确定模 块确定的载频的组网类型控制载频的关断或开启。 优选地， 上述控制模块包括： 第一通知单元， 设置为当上述控制器为 2G的基站 控制器时， 如果需要控制的载频为 3G载频， 通过与 3G的无线网络控制器的接口， 通 知无线网络控制器控制载频的关断或开启； 上述控制模块包括： 第二通知单元， 设置 为当上述控制器为 3G的无线网络控制器时， 如果需要控制的载频为 2G载频， 通过与 2G的基站控制器接口， 通知基站控制器控制载频的关断或开启。 通过本发明， 采用控制器先获取邻区的负载信息， 然后根据负载信息确定需要控 制的载频， 再根据载频的组网类型控制载频的关断或开启， 解决了无法对多个无线网 络重叠覆盖区域的载频进行综合控制的问题， 进而能够综合考虑控制器所在小区与邻 区的用户及业务的分布情况， 从而能够对多个无线网络重叠覆盖区域的载频进行综合 控制。 附图说明 此处所说明的附图用来提供对本发明的进一步理解， 构成本申请的一部分， 本发 明的示意性实施例及其说明用于解释本发明， 并不构成对本发明的不当限定。 在附图 中： 图 1是根据本发明实施例的载频控制方法的流程图； 图 2是根据本发明实施例的载频控制装置的结构框图； 图 3是根据本发明实施例的优选载频控制装置的结构框图;

(4) 3G无线网络控制器对 2/3G同覆盖及包含关系（不包括被包含关系）的邻区 进行判断， 并结合 2/3G 同覆盖载频关断优先关系， 最终确定需要关断的载频。 图 5 是根据本发明实施例一的 2/3G间载频关断消息交互示意图， 如图 5所示，若需要关闭 的是 2G载频， 则由 3G无线网络控制器 （Radio Network Controller, 简称为 RNC)通 知 2G基站控制器 （Base Station Controller, 简称为 BSC)。 2G基站控制器在收到 3G 无线网络控制器的载频关断请求后， 首先对载频关断请求消息中需要关闭的 2G载频 进行决策， 若决策结果为可关闭此 2G载频， 且此 2G载频上尚存少量用户， 则将用户 切换或迁移到 （如强制切换， 但不限于强切手段） 同覆盖小区中； 并向 3G无线网络 控制器回复载频关断请求响应， 反馈是否关闭 2G载频； ( 5 ) 3G无线网络控制器对剩余 2/3G载频进行判断， 决策是否需要开启载频。 在上述步骤 （1 ) 中具体包括以下步骤：
( 1.1 ) 对于多模控制器内部的 3G无线网络控制器和 2G基站控制器， 可能配置 信息交互接口或者标准 Iur-g接口； 若配置信息交互接口， 则定义一套内部消息接口， 用于双模控制器内消息发送时使用， 消息为板间消息； 若配置标准 Iur-g接口， 则需要 在 Iur-g标准消息中， 增加载频关断请求消息和载频关断请求响应消息；
( 1.2) 对于非多模控制器内部的 3G无线网络控制器和 2G基站控制器间 （包括 但不限于， 多模控制器之间、 单模式 3G无线网络控制器和 2G基站控制器之间）， 则 配置标准 Iur-g接口。 在上述步骤 （2) 中具体包括以下步骤：

(4.3 ) 若 （3.2) 中获取到的 3G小区信息， 如剩余等效用户数、 上行 TCP功率、 下行 RTWP干扰、 小区上下行负荷、 上下行 CE、 码资源、 剩余传输资源等因素， 均 小于 （2.2) 中设置的 3G载频关断门限， 则 3G小区载频可关闭；
(4.4) 根据 （4.2) 和 （4.3 ) 的结果， 若 2G小区载频可关闭， 3G小区载频不可 关闭， 3G无线网络控制器则通知 2G基站控制器关闭 2G小区载频， 2G基站控制器在 收到 3G无线网络控制器的载频关断请求消息后， 首先对载频关断请求消息中需要关 闭的 2G载频进行决策， 若决策结果为可关闭此载频， 则将现有 2G业务切换或迁移到 (如强制切换， 但不限于强切手段） 同覆盖小区中， 再进行 2G载频关断操作， 并向 3G无线网络控制器回复载频关断请求响应消息；
(4.5 ) 根据 （4.2) 和 （4.3 ) 的结果， 若 2G小区载频不可关闭， 3G小区载频可 关闭， 3G无线网络控制器首先将现有 3G业务切换或迁移到 （如强制切换， 但不限于 强切手段） 同覆盖小区中， 再通知 3G基站关闭载频；
(4.6) 根据 （4.3 ) 和 （4.4) 的结果， 若 2G、 3G小区载频均可关闭， 3G无线网 络控制器则根据 （2.1 ) 中设置的 2/3G同覆盖载频关断的优先关系进行判决， 即若优 先关断 2G载频， 则后续操作同 （4.4); 若优先关断 3G载频， 则后续操作同 （4.5 );
