Description

一种基站的节能方法及基站
技术领域
本发明涉及移动通信技术, 尤其涉及一种基站的节能方法及基站。
背景技术
随着移动通信技术的发展, 其应用领域也越来越广泛, 在经济生活中的 重要性也越来越高。 移动通信技术的普及与发展不仅适应着越来越高的数据 传输需求, 而且在救援场合、 应急场合、 贫困地区、 偏远地区的应用也越来 越广泛。 然而, 在这些地区和场合, 基站的供电可能不足或不稳, 甚至经常 短缺。 要在这些地区和场合更有效地解决通讯问题, 基站节能就成为很关键 的一个功能。
目前已有的基站节能方法主要有以下几类:
一、在基站正常发送帧的部分时隙减少信号传输,从而达到节能的目的; 二、 设置一个功能模块检测基站的业务流量, 使得基站可以在忙、 闲两 个状态之间切换, 从而达到节能目的, 其重点在于忙、 闲状态的检测;
三、 由操作维护中心控制节能, 基站只负责收集数据, 节能决策由集中 控制中心做出 , 基站根据控制指令完成节能操作;
四、 把基站系统分成几个部分, 其中某些部分(或称为辅助单元)在某 些时间间隔 (没有业务数据处理时) 关闭, 从而实现节能的目的;
五、 基站检测用户数量, 在用户很少的时候, 主动把用户切换到其他基 站, 从而可以关闭本基站以实现节能的目的。
然而, 这些方法的不足之处在于: 其一, 缺乏对基站省电需求程度的判 断和决策。 通常, 这个决策依赖于当前的电源供应状态和当前的业务处理状 态, 尤其是在供电不足的场景下, 这种判断和决策有重要的作用。 而且, 这 种决策只能由基站本身完成(无法依赖集中控制中心,也不能依赖其他基站) 才能确保其效率。原因是: 其一, 虽然通常情况下基站省电有助于节约能源, 但是在最需要省电的场景下尽量保证重要业务能被正常处理有更大的意义; 其二, 在必须省电的场景下, 把基站简单地划分为忙、 闲两种状态, 无法准 确地区分和取舍不同的业务类型, 从而也无法达到最佳的省电效果。 发明内容

本发明的较佳实施方式
下文中将结合附图对本发明的实施例进行详细说明。 需要说明的是, 在 不冲突的情况下, 本申请中的实施例及实施例中的特征可以相互任意组合。 在本实施例中, 基站节能的方法, 包括:
在判断出满足节电条件时, 基站根据当前输入电压确定出包含省电周期 和供电周期的调整周期, 然后在上述省电周期内断电, 在上述供电周期内上 电工作; 其中, 上述节电条件包括: 检测到的输入电压值低于预设的第一阔 值, 或者在检测到在一固定时长内输入电压的变化值超过预设的第二阔值; 每当调整周期结束后, 基站如根据在该调整周期内检测到的输入电压判 断出仍满足节电条件, 则根据在该调整周期内检测到的电压重新确定下一个 调整周期中的省电周期和供电周期, 然后在该重新确定的省电周期内断电, 在该重新确定的供电周期内上电工作; 其中, 检测到的输入电压越低, 根据 该电压确定出的省电周期值越大。 可选地, 在各调整周期内, 供电周期的值 相同。
每当调整周期结束后, 基站根据在该调整周期内检测到的电压判断出满 足恢复条件, 则恢复持续供电。 其中, 所述恢复条件包括: 检测到的输入电 压值高于预设的第一阔值, 或者在检测到在一固定时长内输入电压的变化值 不超过预设的第二阔值。
如图 1所示, 基站系统由节电监测控制单元、 网络数据处理单元、 下行 处理单元、 公共处理单元、 上行处理单元、 下行信号传输处理单元及上行信 号监测接收单元等几部分组成。
各组成单元的具体功能和处理过程描述如下。
1、 节电监测控制单元。 本单元与系统电源相连, 其可以持续检测电源电 压, 并根据检测结果以及系统当前的处理状况控制基站供电或省电, 从而控 制其功耗。 系统电源可以来源于电力网络、 电池或者两者同时使用。
1 ) 对于电力网络电源, 如果电压稳定, 或者有抖动但能保证系统依然 正常安全运行, 本单元不执行任何动作。 如果电压过低(即电源电压低于预 设的第三阔值)或抖动过大(即在一时长内检测到电源电压的变化量大于预 设的第四阔值) , 基站已无法正常安全运行, 则本单元会发送一个中断供电 的消息, 经由公共处理单元发送给上行处理单元和下行处理单元。 无论是否 收到反馈, 在经过一个预定的时间间隔 (T-waiting )之后, 会给操作维护中 心上报电源异常告警, 同时中断系统供电, 即不再将电源电流传送至本基站 中的各其他单元。 基站进入断电状态。 当检测到电源电压恢复正常, 或者电压抖动保持在系统可正常安全运行 范围内, 并维持一段时间 (T-checking ) 以后, 本单元导通系统电源与本基 站中各单元的电连接, 即对基站恢复供电, 同时给操作维护中心上报电源异 常告警的恢复。 系统进入正常状态。
其中 T-waiting和 T-checking固化在系统中, 或者通过配置方式设定。
2 ) 对于电池电源, 通常要使用风能或太阳能对电池进行充电。 当某些 自然原因导致这些能源不足时, 电池就需要节约使用, 以确保其尽可能长时 间使用。
如图 2所示, 当检测到电压高于第一阔值 Th-normal时, 不执行任何动 作, 系统正常供电。 当电压低于 Th-normal但高于第三阔值 Th-saving时, 本 单元会发送一个节电消息, 经由公共处理单元发送给上行处理单元和下行处 理单元。
如果收到的上行处理单元及下行处理单元的反馈都要求推迟进入节电状 态,则本单元将会在一个定时间隔( T-rechecking )之后,根据在该 T-rechecking 时长内检测到的电压情况, 如判断出满足节电条件, 则再次发送节电消息。
如果收到的上行处理单元及下行处理单元任意一个反馈未要求推迟进入 节电状态, 则根据当前电压, 确定一调整周期中节电周期和供电周期的值作 为一组节电数据, 其中供电周期表示在此时长内系统正常供电, 节电周期表 示此时长内中断系统供电。 将该组节电数据经由公共处理单元, 发送给上行 处理单元、 下行处理单元、 以及上行信号监测接收单元。 此后在节电周期时 长内断开系统供电, 基站进入节电状态。
在基站处于节电状态时, 如果节电监测控制单元在当前调整周期内检测 到电池电压持续降低, 则在本调整周期结束后, 重新确定节电周期值, 即增 大节电周期, 反之则减小。 并且在下一个调整周期中按照该重新确定的节电 周期值进行断电处理。 节电周期若发生变化, 会通过节电更新消息经由公共 处理单元发送给上行处理单元、下行处理单元、以及上行信号监测接收单元。 然后本单元在下一个调整周期中按照该重新确定的节电周期值进行断电处 理。
当检测到电压再次高于 Th-normal, 并且维持一段时间 ( T-checking )之 后, 本单元会发送一个节电恢复消息, 经由公共处理单元发送给上行处理单 元、 下行处理单元以及上行信号监测接收单元, 同时恢复供电。 此后系统进 入正常工作状态。
当检测到电压低于第三阔值 Th-saving 时, 本单元会发送一个中断供电 到反馈, 在一个定时间隔 (T-waiting )之后, 会给操作维护中心上报电源异 常告警, 同时中断系统供电。 系统进入关断状态。
当检测到电压再次高于 Th-saving,并且维持一段时间之后( T-checking ), 本单元恢复系统供电。 系统正常工作之后, 本单元会发送一组缺省的节电数 据(包括缺省的供电周期值, 缺省的节电周期值) , 经由公共处理单元发送 给上行处理单元、 下行处理单元以及上行信号监测接收单元。 此后系统按照 该节电数据的值进入节电状态, 同时给操作维护中心上报电源异常告警的恢 复。 缺省的节电数据固化在系统中, 或者通过配置设定。 节电状态的处理, 同如上所述, 在此不再进行赞述。
其中 Th-normal、 Th-saving ¾ T-rechecking固化在系统中, 或者通过配置 方式设定。
3 ) 对于电力网络电源和电池电源同时存在的情况, 本单元会同时持续 检测电力网络电源电压和电池电压。然后根据检测结果,可以分成几类情况, 具体处理如下:
i:电力网络电源正常, 使用电力网络电源;
ii:电力网络电源由正常变为异常, 选择电池电源, 而后处理过程与 2 ) 相同;
iii:电力网络电源持续异常, 选择电池电源, 处理过程与 2 )相同; iv:电力网络电源恢复正常, 并持续一段时间 (T-checking )之后, 使用 电力网络。
此外, 本单元内嵌充放电模块, 在基站系统正常供电的时候, 充放电模 块被充电, 同时本单元使用系统电源供电。 在系统供电不正常的时候, 充放 电模块将放电, 以确保本单元在此条件下也能正常工作, 从而确保本单元在 任何条件下都能对系统电压做出正确的检测和判断。
2、网络数据处理单元,负责完成基站与网络侧网元间交互的数据的收发。 网络侧数据在本单元处理之后, 经由公共处理单元被发送给下行处理单元; 空口数据在上行处理单元处理完成之后 ,经由公共处理单元被发送给本单元, 再通过本单元发送给相应的网络侧网元。 例如 , WiMAX ( Worldwide Interoperability for Microwave Access , 全球微波互联接入)基站系统中的 R6/R8接口的数据收发; 或者 LTE ( Long Term Evolution, 长期演进)基站 系统中 X2/S1接口的数据收发。 本单元不参与基站系统的节能决策。 在基站 系统为节电状态或关断状态时, 本单元将停止工作。
3、 下行处理单元, 负责完成下行业务的处理、 空口资源的分配以及终端 用户各类请求的回复或发起等。 下行数据经下行信号传输处理单元发送给终 端用户。 下行数据通常由广播数据、 多播数据和单播数据组成。 广播数据可 能需要周期性发送; 而多播和单播数据则是在相应的终端用户有业务或数据 的时候才需要发送。 空口资源的分配方式主要有两种,一种是持续分配方式, 一种是按需分配方式。 持续分配是指在一定周期内, 持续给终端用户分配资 源, 直到终端用户业务结束或发出终止请求, 通常用于分配上行资源; 按需 分配是指根据终端用户的需要, 例如待传输的数据量或者用户请求的资源数 量, 来给终端用户分配资源。 在下行方向上, 一般是依据待传输的数据量来 确定是否发送请求延长节电周期的消息; 在上行方向上, 一般是依据请求数 量来确定是否发送请求延长节电周期的消息。 如请求数量减少或待传输的数 据量减少, 则可在这些终端用户和各种业务类型之中, 某些终端用户或某些 业务类型有更高的优先级, 应该在供电周期内被优先处理。 例如, 紧急呼叫 业务应该以最高优先级被发送, 金牌用户比其他用户有更高的优先级等。 当收到节电监测控制单元发送的、 经由公共处理单元发送到本单元的中 断供电消息时, 说明基站系统的供电已经不足, 将会被很快关断, 本单元在 完成必要数据的存储、 终端用户资源的释放等工作后, 经由公共处理单元给 节电监测控制单元回复一个响应消息, 同时等待系统电源被关断。
当收到节电监测控制单元发送的、 经由公共处理单元发送到本单元的节 电消息时, 说明基站出现供电不足, 必须省电使用。 本单元向节点监测控知 单元发送响应消息, 进入节电状态。
当收到节电恢复消息时, 本单元不做处理, 仅记录基站系统的状态为正 常状态。
如表 1所示, 本单元维护四种状态, 具体处理过程如下:
1 )本单元启动之后, 处于正常状态。 收到节电消息之后, 进入一类省电 状态, 同时回复响应消息, 建议系统推迟进入节电状态;
2 )处于一类省电状态时, 如果再次收到节电消息, 那么状态不变, 直接 回复响应消息, 接受基站系统进入节电状态。 在本状态, 会周期检测本单元 记录的基站系统的状态, 如果基站系统状态为正常状态, 那么持续一段时间 ( T-checking )之后, 本单元进入二类省电状态。
3 )处于二类省电状态时,如果收到节电消息,将立刻变为一类省电状态, 同时回复反馈消息, 建议系统推迟进入节电状态。 此状态下会周期检测本单 元记录的基站系统的状态, 如果基站系统状态为正常状态, 那么持续一段时 间 ( T-checking )之后, 本单元进入三类省电状态。
4 )处于三类省电状态时,如果收到节电消息,将立刻变为一类省电状态, 同时回复反馈消息, 建议系统推迟进入节电状态。 此状态下会周期检测本单 元记录的基站系统的状态, 如果基站系统状态为正常状态, 那么持续一段时 间 ( T-checking )之后, 本单元进入正常状态。
表 1 下行处理单元的状态列表 一类省电 处理紧急呼叫业务、 广播业务 处理紧急呼叫业务、 广播业
二类省电
务、 金牌用户的业务 处理紧急呼叫业务、 广播业
三类省电
务、 金牌、 银牌用户的业务 正常 处理所有业务 处于一类、 二类、 三类省电状态下, 本单元完成数据的处理, 并经下行 信号传输处理单元发送完成之后, 将立刻关闭下行信号传输处理单元。 直到 下次发送之前再开启。 而正常状态下, 下行信号传输处理单元将一直正常开 启。
4、下行信号传输处理单元,用于在接收到下行处理单元的处理结果之后, 完成下行数据的传输和发送。 本单元不参与基站系统的节能决策。 在基站系 统处于节电状态或关断状态时, 本单元将停止工作。
5、 公共处理单元, 主要完成公共数据、 消息、 事件的存储和处理。 网络 数据处理单元、 上行处理单元、 下行处理单元、 节电监测控制单元、 上行信 号监测接收单元等这些不同单元之间的消息交互、 数据存储和读取、 事件处 理, 都通过本单元完成。 本单元不参与基站系统的节能决策。 在基站系统的 节电状态或关断状态, 本单元将停止工作。
6、上行处理单元, 用于完成上行数据的接收和处理。 如果系统中激活终 端数比较多, 或者上行数据量比较大, 基站系统就需要消耗更多的时间和资 源来处理上行数据。 反之, 则上行数据的处理需要消耗的时间和资源就比较 少。 在基站电量不足的时候, 上行数据处理应该以最小的时间和资源消耗来 完成。 上行处理的数据主要有三种, 一种是终端用户的业务数据, 另一种是 终端用户的上行资源请求, 第三种是终端用户和基站之间的控制消息。 业务 数据最终会经过网络数据处理单元发送给网络侧网元。 终端用户的上行资源 请求经公共处理单元发送给下行处理单元, 下行处理单元会根据终端用户的 状态、 可用资源、 以及用户信息等决定可供分配的数量, 分配结果最终会发 送给终端用户。 控制消息则由上行处理单元处理, 处理结果经公共处理单元 发送给下行处理单元, 并最终会发送给终端用户。
当收到节电监测控制单元发来的、 经由公共处理单元发送到本单元的中 断供电消息时, 说明基站系统的供电已经不足, 将会被很快关断, 本单元在 完成必要数据的存储、 终端用户资源的释放等工作后, 会给节电监测控制单 元回复一个响应消息, 同时等待电源被关断。
当收到节电监测控制单元发来的、 经由公共处理单元发送到本单元的节 电消息时, 如果本单元当前不处于省电状态, 将进入省电状态, 同时回复响 应消息, 建议基站系统延迟进入省电状态; 本单元当前处于省电状态, 将回 复响应消息, 接受基站系统进入省电状态。
具体而言, 本单元维护两种工作状态: 正常状态、 省电状态, 具体的处 理过程如下:
1 )本单元初始状态为正常状态, 收到节电消息之后, 将开启上行信号监 测接收单元, 同时回复响应消息, 建议系统推迟进入节电状态, 同时本单元 进入省电状态。
2 )处于省电状态时, 在供电周期内, 除以下两种条件外, 其余时间本单 元停止工作。 其一, 上行信号监测接收单元探测到了合法信号, 将启动本单 元在一个时间间隔( T-working ) 内正常工作, 此时上行信号监测接收单元被 关闭, 上行接收处理恢复为正常状态; 超过这个间隔之后, 将再次开启上行 信号监测接收单元。 其二, 下行处理单元根据空口资源分配结果, 经过公共 处理单元发送消息通知本单元在下一个帧周期需要接收上行数据, 本单元将 在下一个帧周期开始之前关闭上行信号监测接收单元, 上行接收处理恢复为 正常状态; 在下一个帧周期结束之后, 再次开启上行信号探测接收单元。 如 果在省电状态收到节电消息, 将直接回复响应消息, 接受基站系统进入节电 状态。 如果收到节电恢复消息, 本单元恢复为正常状态, 上行信号监测接收 单元被关闭, 上行接收处理恢复为正常状态。 其中 T-working固化在系统中, 或者通过配置方式设定。
7、上行信号监测接收单元, 包含两种功能: 上行信号探测和上行信号接 收。
在基站系统的节电状态的省电周期内或关断状态, 本单元将停止工作。 在正常状态下,上行信号探测功能被关闭,上行信号接收功能正常工作。 当上行处理单元进入省电状态时, 在供电周期内, 上行信号探测接收单 元的探测功能被打开, 此时仅在一个很小的间隔内接收上行信号, 如果探测 到的信号功率超过某个阔值(Th-signal ) , 将触发上行信号接收功能正常工 作, 并通知给上行处理单元。 此时, 上行信号探测功能关闭, 上行信号接收 功能正常工作。 在一个定时间隔(T-working )之后, 上行处理单元将再次开 启上行信号探测功能。 在省电周期内, 上行信号监测接收单元再次被关闭。
其中 Th-signal固化在系统中, 或者通过配置方式设定。
8、 操作维护中心。 操作维护中心的主要功能是维护、 操作、 监控和诊断 基站系统, 通常放置于运营商的机房中。 操作维护中心与基站系统通过网络 完成信息的交互。 例如, 当操作维护中心收到电源异常告警时, 操作人员能 观察到这个异常。 当告警恢复时, 说明基站系统已经恢复正常工作。
本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序 来指令相关硬件完成, 所述程序可以存储于计算机可读存储介质中, 如只读 存储器、 磁盘或光盘等。 可选地, 上述实施例的全部或部分步骤也可以使用 一个或多个集成电路来实现。 相应地, 上述实施例中的各模块 /单元可以釆用 硬件的形式实现, 也可以釆用软件功能模块的形式实现。 本发明不限制于任 何特定形式的硬件和软件的结合。
