基站功放保护方法及装置
本申请要求于 2006 年 1 月 10 日提交中国专利局、 申请号为 200610032779.0、发明名称为 "基站功放保护方法及装置 "的中国专利申请 的优先权, 其全部内容通过引用结合在本申请中。
技术领域
本发明涉及基站技术, 更具体的说, 本发明涉及一种基站功放保护的 方法及装置。
背景技术
基站射频功放能力是影响通信系统中小区容量与覆盖的一个因素。 通 常在无线网络规划阶段, 根据基站功放能力和无线环境等等因素综合配置 小区的功率资源。 但在某些情况下, 功放能力有可能发生变化, 如基站
( NodeB )射频功放出现过温时, 为了避免设备的损坏, 需要对基站功放 进行保护„
目前对基站功放的保护采用直接限制的方式, 例如当检测到基站功放 出现过温时(即基站功放温度超过预定门限), 一般采用直接限制基站功放 进行保护, 采用该种方式虽然可实现对基站功放的保护, 但会对业务造成 很大的影响, 因为当采取这种方式时, 基站覆盖的小区就不存在了, 正常 的通信会中断。
发明内容
本发明解决的技术问题是提供一种基站功放保护的方法及装置, 以降 低基站功放保护对业务的影响, 保证正常的通信不会中断。
为解决上述问题, 本发明提供一种基站功放保护的方法, 包括步骤: 确定触发基站功放保护;
在基站中限制非公共信道的发射功率, 以降低基站功放功率实现基站 功放保护。
另外, 本发明还提供一种基站功放保护的装置, 包括:
功放保护触发判断单元, 用于判断是否触发基站功放保护, 若是, 则 发送限制非公共信道发射功率的指示;
功放保护执行单元, 在接收到功放保护触发判断单元的指示后, 限制 非公共信道的发射功率, 以降低基站功放功率实现基站功放保护。
由上述公开的技术方案可知, 本发明通过检测基站的功放温度来确定 是否触发基站功放保护, 若功放温度过高(超过预定的门限值), 则通过在 基站中限制 (比如关闭和减小)非公共信道的发射功率, 来降低基站功放 功率, 从而实现基站功放保护, 保证小区正常的通信不会中断。
附图说明 图 1是本发明实现基站功放保护的方法主要流程图;
图 2是本发明所述方法中采用拥塞控制的方式限制非公共信道发射功 率的流程图;
图 3是本发明基站功放保护的装置的结构示意图。
具体实施方式
本发明的核心在于确定触发基站功放保护后, 在基站中限制 (降低或 关闭) 非公共信道的发射功率, 以降低基站功放功率, 实现对基站功放的 保护。 本发明所述方案仅通过限制非公共信道的发射功率, 就可以保证小 区的覆盖不变, 从而保证正常的通信不会中断。
下面结合附图对本发明作进一步的说明。
请参阅图 1 , 为本发明实现基站功放保护的方法的流程图。 所述方法 包括:
步骤 S11 : 确定触发基站功放保护;
步骤 S12: 在基站中限制非公共信道的发射功率, 以降低基站功放功 率实现基站功放保护。
在某些情况下, 基站功放能力有可能发生变化, 如空调突然坏掉导致 基站 (NodeB )功放温度超过预定门限(即过温) 时, 则需要采取措施对 基站功放进行保护, 也就是说, 当检测到基站的功放温度超过额定值时, 产生过温告警, 启动触发基站功放保护。 但是在实际应用中, 实际触发基 站功放保护的情况还有多种, 比如: 小区输出功率过大, 超过功放设计要 求等, 由于不涉及本发明实质, 这里不再赘述。
本发明可以采用修改拥塞控制的方式限制非公共信道的发射功率来实 现基站功放保护, 也可以采用其他的方式实现基站的功放保护。 下面以此 为例进行说明。
请参考图 2, 为本发明所述方法中采用拥塞控制的方式限制非公共信 道发射功率的流程图, 其具体的实现过程为:
步驟 T11: 若基站功放出现过温时, 修改拥塞控制门限为预定值, 使 其进入拥塞控制启动状态;
所述拥塞控制门限是软件程序中的一个变量, 可以由软件直接修改为 预定值。 由于拥塞控制本身是为了控制功放输入信号, 降低拥塞控制门限, 实际上就是限制功放输入信号, 所述预定值为不大于正常情况下拥塞控制 门限值 (如为正常情况下拥塞控制门限的 50 % ,但并不限于此,还可以是拥 塞门限的 60 %、 70 %等); 也可以是一个较低的值(如 30 %等), 即可使小 区进入拥塞控制启动状态, 也就是说, 在小区的发射功率还没有达到正常 情况下拥塞门限时, 就使该小区进入拥塞控制启动状态;
步驟 T12: 基站进入拥塞控制状态后, 通过拥塞控制限制非公共信道 发射功率, 保持公共信道发射功率不变。
在该步驟中, 对于所述的非公共信道一般都有功率控制, 每个信道根 据功率控制的要求升高或者降低信道的发射功率, 启动拥塞控制后, 可以 要求非公共信道根据功率控制要求降低信道发射功率, 当功率控制要求升 高发射功率时, 可以保持公共信道的功率不变。 从而可达到降低基站功放 功率的目的同时保证小区覆盖不变。
比如说, 本发明可以通过降低或关闭非公共信道(比如专用信道) 的 发射功率, 来控制基站的功放功率。 其具体的过程为: 当出现小区实际发 射功率超过小区最大发射功率阈值的情况时, NodeB降低或关闭一个或多 个非公共信道(比如专用信道) 的业务速率, 以达到降低小区发射功率, 实现基站功放的保护。 现分別对降低或关闭非公共信道的业务速率进行举 例说明: 当基站温度升高达到一定值时, 修改拥塞门限为原来的 50 % , 此时启 动拥塞算法, 并判断小区的发射功率是否超过修改后的拥塞门限, 如果超 过, 则降低非公共信道的发射功率, 直至小区的发射功率小于修改后的拥 塞门限为止。 在该拥塞门限的控制过程中, 非公共信道的发射功率只能下 降或者保持, 但不上升, 如果上升, 则小区的发射功率也会升高, 进而导 致基站温度升高。 在该过程结束后, 如果小区的发射功率低于拥塞门限, 则不起动拥塞控制算法, 非公共信道的发射功率可以上升或保持。
当基站温度升高达到一定值时, 修改拥塞门限为原来的 50 % , 此时拥 塞算法会判断小区发射功率是否超过修改后的拥塞门限, 如果超过, 则按 照优先级从低到高的顺序关闭非公共信道的发射功率, 直到小区发射功率 小于修改后的拥塞门限。
再例如, 将某些业务采用无数据的传输格式来进行信道编码及无线帧 映射, 这样在空中发射时该业务由于没有数据而占用很少的发射功率。 对 于专用信道的选取, 可以有很多准则, 例如根据用户优先级, 先降低或者 关闭低优先级的用户; 以及先降低或者关闭功率最大信道的功率等等。
也就是说, 本发明在具体实现时, 可采用拥塞控制方式在基站中限制 非公共信道的发射功率, 比如通过降低或关闭(可以根据用户的优先级降 低或关闭)一个或多个非公共信道的发射功率, 保持公共信道的发射功率 不变, 这样即可保证下行发射功率不超出功放能力, 又能保证小区覆盖不 变, 从而保证正常的通信不会中断。
还请参阅图 3 , 为本发明所述基站功放保护的装置的结构示意图, 所 述装置包括: 功放保护触发判断单元 31和功放保护执行单元 32。 其中所 述功放保护触发判断单元 31主要用于判断是否触发基站功放保护, 若是, 则发送限制非公共信道发射功率的指示; 所述功放保护执行单元 32, 在接 收到功放保护触发判断单元 31的指示后, 限制非公共信道的发射功率, 以 降低基站功放功率实现基站功放保护。
所述功放保护触发判断单元 31主要包括: 检测判断子单元 311 , 用于 检测基站功放温度是否超过预定门限; 指示子单元 312, 根据检测判断的 结果, 启动基站功放保护, 并发送限制非公共信道发射功率的指示。 也就 是, 在所述检测判断子单元检测到基站功放温度超过预定门限后, 发送限 制非公共信道的发射功率的指示。 所述功放保护执行单元 32包括: 修改子 单元 321 , 与指示子单元 312相连, 用于 改拥塞控制门限为预定值, 使 基站进入拥塞控制启动状态; 拥塞控制子单元 322, 与修改子单元 321相 连, 用于在基站进入拥塞控制后, 保持公共信道发射功率保持不变, 限制 非公共信道发射功率。所述功放保护执行单元 32可采用拥塞控制方式在基 站中限制非公共信道的发射功率。
所述装置中各个单元的功能和作用的实现过程详见上述方法中各个步 骤的实现过程, 在此不再赘述。
以上所述仅是本发明的优选实施方式, 应当指出, 对于本技术领域的 普通技术人员来说, 在不脱离本发明原理的前提下, 还可以作出若干改进 和润饰, 这些改进和润饰也应视为本发明的保护范围。
