Description

一种载频调配的方法与基站 本申请要求于 2008年 3月 26日提交中国专利局、申请号为 200810066197. 3 , 发明名称为"一种载频调配的方法与基站 "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 本发明属于通信技术领域, 尤其涉及一种多载频系统中载频调配的方法与 基站。 背景技术 随着无线通信的发展, 系统中的移动用户数量越来越多, 为了增加系统容 量, 通常釆用的方法是增加扇区 (或小区)数和增加载波频率个数。 所谓扇区 (或小区)是指利用有向天线将一个圓形区域分成多个扇形区域。 在本发明中, 为了便于说明, 统一将扇区或小区称作扇区。 在移动通讯系统中, 典型的扇区 有三种, 分别为全向扇区、 三扇区和交扇区。 根据网絡系统的规划设计方法, 一般可将某个地理区域规划成 m * n个小区的网絡系统。 其中, m表示扇区数目, n表示每个扇区的载频数目。 比如说, 在 CDMA2000 系统网絡规划设计时, 将 某一个地区规划成 3 * 4的网絡系统, 则表示将该地区基站配置为 3个扇区, 每个 扇区有 4个载频, 即共有十二个载扇; 如果规划成 6 * 2的网絡系统, 则表示将该 地区基站配置为 6个扇区, 每个扇区有 2个载频。 为了让扇区中的每个用户都能 顺利接入网絡, 扇区中的载频都是处于开启状态, 即基站在任何时刻无论其所 负责的每个载波的当前用户量为多少, 包括当前用户量极少甚至为零时, 仍然 要按照最大发射功率工作, 会造成基站的功率大量浪费, 从而在很大程度上增 力口了运营成本。 发明内容 本发明实施例提供了一种载频调配的方法与基站, 以解决上述扇区中的载 频因固定处于开启状态, 导致基站功耗大量浪费的问题。
本发明的实施例提供的一种载频调配的方法包括以下步骤:
检测网絡所处的状态;
若网絡所处的状态为闲时, 则将叠加载频上的用户迁移到基本载频; 闭塞叠加载频。
本发明的实施例提供的另一种载频调配的方法包括以下步骤:
检测网絡所处的状态以及叠加载频的状态;
若网絡状态处于闲时, 且叠加载频为开启状态, 则将叠加载频上的用户迁 移到基本载频, 并闭塞叠加载频。
本发明的实施例还提供了一种载频调配的基站, 该基站包括:
检测单元, 用于检测网絡所处的状态;
迁移单元, 用于在检测单元检测到网絡所处的状态为闲时, 将叠加载频上 的用户迁移到基本载频;
第一处理单元, 用于在迁移单元将叠加载频上的用户迁移到基本载频后, 闭塞叠加载频。
通过上述本发明提供的技术方案, 可以在网絡处于闲时, 关闭叠加载频, 由于此时消耗功率的只有基本载频, 所以在很大程度上降低了基站的功率, 节 省了运营成本。 附图说明 图 1为本发明实施例一载频调配方法的流程示意图;
图 2为本发明实施例二载频调配方法的流程示意图;
图 3为本发明实施例三载频调配方法的流程示意图;
图 4为本发明实施例基站的结构示意图;
图 5为本发明实施例基站中检测单元的第一结构示意图;
图 6为本发明实施例基站中检测单元的第二结构示意图。 具体实施方式 本发明实施例提供了一种载频调配的方案, 在该方案中, 基站可以根据网 絡的状态来开启或闭塞部分载频, 由此可以解决现有技术中即使网絡处于闲时, 所有载频仍旧全部开启导致基站功耗大量浪费的问题。
在实施本发明实施例所介绍的方法之前, 可以在操作维护中心设置某些载 频为基本载频, 其他载频为叠加载频。 基本载频可以根据网絡的具体情况进行 设置, 例如, 若多载频网絡中有某个或某些频点的覆盖是最为广泛的, 那么就 设置这个或这些频点的载频为基本载频; 若多载频网絡中所有频点的覆盖都是 差不多的, 则可任意选择其中一个或几个频点的载频为基本载频。 在设置基本 载频时, 尽量保证基本载频覆盖的连续性。 在通常情况下, 基本载频的容量要 能够容纳闲时用户使用, 所以基本载频的个数可以根据闲时网絡负载情况进行 确定。
在介绍完基本载频和叠加载频的设置之后, 下面将对照附图对本发明实施 例所述的方法进行详细的说明。
参见图 1 , 本发明实施例一提供的载频调配方法包括以下步骤:
步骤 101 : 检测网絡所处的状态;
在本发明的实施例中, 可以将网絡的状态划分为闲时和忙时两种情况, 检 测网絡所处的状态方法有很多, 下面对比较常用的两种方法进行介绍。
一是静态设置方式, 即可以根据当前网絡情况和以往网絡长期运行的情况, 设置某一段或某几段时间为闲时和忙时, 然后基站系统根据时间来判断网絡是 否进入闲时和忙时。 例如通过对用户使用时间分布的分析, 发现每天 00: 00— 09: 00话务量明显较少, 而其他时间话务量较高, 则可将 10: 00 - 23: 59设置 为忙时, 而 00: 00 - 09: 00设置为闲时。
二是动态判断方式, 基站系统可以根据扇区的负荷或用户数来判断网絡是 处于忙时还是闲时。 当负荷低于预设的闲时负荷门限时 (或是负荷低于预设的 闲时负荷门限的时间超过预设的第一时间段后) , 就判断网絡进入闲时; 若负 荷高于预设的忙时负荷门限时 (或是负荷高于预设的忙时负荷门限的时间超过 预设的第二时间段后) , 就判断网絡进入忙时。 上述的闲时负荷门限与忙时负 荷门限可以为同一个值, 也可以为避免产生乒乓效应设置为不同的值。 第一时 间段和第二时间段均可以通过定时器来设置。 上述的负荷可以通过前向发射功率、 反向 RSSI ( received signal strength indicator, 接收信号强度指示) 、 ROT ( ROT Rise Over Thermal 底噪抬升) 、 时隙占用率等指标中的一种来进行衡量, 也可以通过这些指标中的几种来进行 综合衡量。 例如, 用前向发射功率来衡量网絡的负荷, 当前向发射功率低于一 定门限 (门限可设置, 如前向发射功率超过额定功率 50 % ) 时(或低于一定门 限的时间超过预设的时间段后) , 就判断网絡进入闲时; 反之, 则判断网絡进 入忙时。 上述的负荷也可以为前向发射功率、 反向 RSSI、 ROT、 时隙占用率等 指标其中几个的综合情况, 比如 ROT低于 5dB, 且前向发射功率低于额定功率 50 %的时间超过预设的时间段(预设的时间段可以由定时器设置)后, 判断网 絡进入忙时; 反之, 则判断网絡进入忙时。 除此之外, 也可以是上述几个指标 中其中之一满足一定条件, 就判断网絡进入闲时, 如 ROT低于 5dB, 或前向发 射功率低于额定功率 50 %的时间超过预设的时间段后, 就判断网絡进入闲时; 反之, 则判断网絡进入忙时。
上述负荷的衡量方法有很多种, 在此无法——穷举, 因此本领域技术人员 在使用本发明实施例所述的方法时, 可以根据网絡的实际情况进行灵活处理。
步骤 102: 若网絡所处的状态为闲时, 则将叠加载频上的用户迁移到基本载 频;
将叠加载频上的用户迁移到基本载频可以釆用 Handdown硬切换方式。 Handdown硬切换利用相同扇区不同载频间覆盖基本一致和同扇区内硬切换成 功率高的特点, 可以直接命令用户同时硬切换到数据库预先配置好的同扇区 Handdown基本载频和相邻的基本小区的基本载频。
步骤 103: 闭塞叠加载频。
叠加载频闭塞后, 叠加载频的增益下降至 OdB左右, 此时不再向外发射信 号, 也就不消耗功率了。
通过上述本发明实施例所描述的方法, 可以在网絡处于闲时时, 关闭叠加 载频, 而关闭叠加载频后消耗功率的只有基本载频, 所以在很大程度上降低了 基站的功率, 节省了运营成本。
由于网絡的状况总是处于变化的状态, 当网絡的状态由闲时变为忙时, 基 本载频会不够用户使用, 此时需要开启叠加载频, 本发明的实施例二提供了一 种解决方法, 具体参见图 2, 步骤 201〜步骤 203与步骤 101〜步骤 103类似, 所 以在此不再详述, 该实施例与实施例一的区别之处在于多了如下步骤:
步骤 204: 检测网絡所处的状态;
步骤 205: 若网絡所处的状态由闲时转为忙时, 则开启叠加载频。
步骤 204中检测网絡所处状态的方法与实施例一的步骤 101相似, 通过步 骤 204和步骤 205 ,本发明的实施例二可以实现在网絡的状态由闲时转为忙时时 , 开启叠加载频, 以避免在用户数量较大的情况下网絡资源不够使用的问题。
上述实施例一和实施例二所描述的进行载频调配的方法流程中, 当检测到 网絡所处的状态为闲时, 有可能叠加载频已经闭塞, 此时就不需要再进行闭塞 叠加载频的操作了; 而当检测到网絡所处的状态为忙时, 有可能叠加载频本就 处于开启状态, 此时也无需再进行开启叠加载频的操作了。 为此本发明实施例 三提供了一种解决方案, 参见图 3 , 本发明实施例三涵盖了四种可能的情况, 其 主要包括如下步骤:
步骤 301 : 检测网絡所处的状态以及叠加载频的状态;
步骤 301 中检测网絡所处状态的方法与实施例一的步骤 101相似, 所以在 此不再详述。
步骤 302: 根据网絡所处的状态以及叠加载频的状态进行相应的操作。
参见表 1 所示, 根据网絡所处的状态以及叠加载频的状态进行相应的操作 具体可以分为如下四种情况:
1 )若网絡状态处于闲时, 且叠加载频为开启状态, 此时进行的相应操作为 将叠加载频上的用户迁移到基本载频, 并闭塞叠加载频;
2 )若网絡状态处于闲时, 且叠加载频为闭塞状态, 此时可不进行任何操作;
3 )若网絡状态处于忙时, 且叠加载频为开启状态, 此时可不进行任何操作;
4 )若网絡状态处于忙时, 且叠加载频为闭塞状态, 则此时进行的相应操作 为开启叠加载频。 表 1
Figure imgf000008_0001
上述实施例一、 实施例二或实施例三所描述的进行载频调配的流程, 均可 以由网絡管理人员根据小区或扇区当前的网絡状况启动, 也可以通过定时器触 发, 周期性地启动。
本发明的实施例还提供了一种基站, 参见图 4所示, 该基站包括: 检测单元 41 , 用于检测网絡所处的状态;
迁移单元 42, 用于在检测单元 41检测到网絡所处的状态为闲时, 将叠加载 频上的用户迁移到基本载频;
第一处理单元 43 ,用于在迁移单元 42将叠加载频上的用户迁移到基本载频 后, 闭塞叠加载频。
由于网絡的状况总是处于变化的状态, 当网絡的状态由闲时变为忙时, 基 本载频会不够用户使用, 此时需要开启叠加载频, 因此所述的基站还包括: 第二处理单元 44, 用于在检测单元 41检测到网絡所处的状态为忙时, 开启 叠加载频。
若釆用静态设置的方式来检测网絡所处的状态, 则参见图 5 , 上述的检测单 元 41具体包括: 第一决策单元 4102,用于根据第一比较单元 4101的比较结果确定网絡所处 的状态。如果第一比较单元 4101将网絡所处的时间与预设的闲时时间段比较后, 发现网絡所处的时间在预设的闲时时间段内, 则第一决策单元 4102确定网絡所 处的状态为闲时; 如果第一比较单元 4101将网絡所处的时间与预设的闲时时间 段比较后,发现网絡所处的时间不在预设的闲时时间段内,则第一决策单元 4102 确定网絡所处的状态为' 1"亡时。
若釆用静态设置的方式来检测网絡所处的状态, 则参见图 6, 上述的检测单 元 41具体包括: 第二决策单元 4112,用于根据比较单元 4111的比较结果确定网絡所处的状 态。 如果第二比较单元 4111将网絡的负荷与预设的负荷门限比较后, 发现网絡 的负荷小于预设的负荷门限,则第二决策单元 4112确定网絡所处的状态为闲时; 如果第二比较单元 4111将网絡的负荷与预设的负荷门限比较后, 发现网絡的负 荷大于预设的负荷门限, 则第二决策单元 4112确定网絡所处的状态为忙时。
通过上述本发明实施例所描述的基站, 可以在网絡处于闲时时, 关闭叠加 载频, 由于关闭叠加载频后消耗功率的只有基本载频, 所以可以在很大程度上 降低基站消耗的功率, 节省运营成本。

7、 根据权利要求 1所述的方法, 其特征在于, 将叠加载频上的用户迁移到 基本载频具体为: 将叠加载频上的用户通过硬切换的方式迁移到基本载频。
8、 一种载频调配的方法, 其特征在于, 所述的方法包括如下步骤: 检测网絡所处的状态以及叠加载频的状态;
若网絡状态处于闲时, 且叠加载频为开启状态, 则将叠加载频上的用户迁 移到基本载频, 并闭塞叠加载频。
9、 根据权利要求 8所述的方法, 其特征在于, 所述的方法还包括: 若网絡状态处于忙时, 且叠加载频为闭塞状态, 则开启叠加载频。
10、 根据权利要求 8所述的方法, 其特征在于, 所述的方法还包括: 若网絡状态处于闲时, 且叠加载频为闭塞状态, 则不进行任何操作; 若网絡状态处于忙时, 且叠加载频为开启状态, 则不进行任何操作。
11、 一种基站, 其特征在于, 所述的基站包括:
检测单元(41 ), 用于检测网絡所处的状态;
迁移单元(42 ), 用于在检测单元(41 )检测到网絡所处的状态为闲时, 将 叠加载频上的用户迁移到基本载频;
第一处理单元(43 ), 用于在迁移单元(42 )将叠加载频上的用户迁移到基 本载频后, 闭塞叠加载频。
12、 根据权利要求 11所述的基站, 其特征在于, 所述的基站还包括: 第二处理单元(44 ), 用于在检测单元(41 )检测到网絡所处的状态由闲时 转为忙时, 开启叠加载频。
13、根据权利要求 11或 12所述的基站,其特征在于,所述的检测单元(41 ) 具体包括: 较;
第一决策单元(4102 ), 用于根据第一比较单元(4101 ) 的比较结果确定网 絡所处的状态。
14、 根据权利要求 11或 12所述的基站, 其特征在于, 所述的检测单元具 体包括: 第二决策单元(4112 ), 用于根据第二比较单元(4111 ) 的比较结果确定网 絡所处的状态。
