Description
一种载频调整方法和系统
技术领域
本发明涉及移动通信技术领域,特别是涉及一种载频调整方法和 系统。 背景技术
对于 TD-SCDMA (时分-同步码分多址, Time Division - Synchronous Code Division Multiple Access )系统, 其所拥有的无线频 带资源通常被划分为若干载频, 这些载频上承载公共信道和 /或专用 信道。而 TD-SCDMA系统中的 RNC(无线网络控制器, Radio Network Controller )负责为这些载频分配信道, 其中, 每个信道具有对应的频 点。
FODCA (频率优化动态信道分配, Frequency Optimization Dynamic Channel Allocation )是一种典型的信道分配方法, 它将小区 划分为干扰带和非干扰带; 对于 UE (用户设备, User Equipment )来 说, 在干扰带优先使用配置的最佳频点, 而在非干扰带尽量不使用最 佳频点; 由于网络规划时 N频点小区其主频点基本都是异频的, 因 而在干扰带可以尽量避免同频干扰。
参照图 1 , 现有 FODCA的实现方案具体可以包括:
步骤 101、 通过当前 UE上报的导频值, 判断该 UE是否跨区域, 若是, 则触发该 UE的载频调整;
对于当前 UE, 在其接入小区网络后, 从非干扰带进入干扰带, 或者从干扰带进入非干扰带, 均可视为跨区域。
现有技术中,步骤 101主要利用 RSCP(接受信号码功率, Receive Signal Code Power )值来表示所述导频值, 所述判断跨区域的方法如 下:
如果 RNC中的当前 UE的区域信息表明, 当前 UE处于"非干扰 带", 若当前 UE所在小区的邻小区都满足如下条件:
PCCPCH_RSC¾ - PCCPCH— RSCP^ ≥ Tk— ALPHA-……①^ 表明当前 UE仍处于 "非干扰带"; 否则, 该 UE处于 "干扰带"。 其中, PCCPCH_RSCPs 为当前 UE 所在小区的 RSCP 值, PCCPCH_RSCPAdji为当前 UE所在小区的某临小区的 RSCP值, 其 中, Th=3 ~ 6dB, ALPHA=0~3dB。
或者,如果 RNC中的当前 UE的区域信息表明,当前 UE处于"干 扰带", 若当前 UE所在小区的邻小区中任意一个满足如下条件:
PCCPCH_RSCPS - PCCPCH.RSCP^^ < Th + ALPHA -…… 表明当前 UE仍处于 "干扰带"; 否则, 该 UE处于"非干扰带"。 举例来说, 假设当前 UE的原区域信息为: 处于"非干扰带", 其 原载频不使用最佳频点, 而当前 UE所在小区的某一临小区不满足公 式①, 则表明当前 UE的新区域信息为: 处于 "干扰带", 而该新区 域信息要求使用最佳频点; 因此,在当前 UE从非干扰带进入干扰带, 需要触发原载频的调整。
同理,在当前 UE从干扰带进入非干扰带,也需要触发载频调整。 步骤 102、 在载频调整完成后, 通过启动 FDCA算法定时器来防 止频繁的载频调整。
也即, 在 FDCA (快速动态信道分配, Fast Dynamic Channel
Allocation )定时器超时之前, 不针对当前 UE进行步骤 101中的载频 调整操作。
现有 FODCA的实现方案主要有如下缺陷:
1、 仅使用导频值来判断 UE是否跨区域, 进而在跨区域时引发 UE在不同频点中的频繁调整; 通过外场的测试发现, 即使 UE没有 在小区内发生任何移动, 其上报的导频值也会存在几个 dB的抖动, 从公式①和公式②可知, 视 ALPHA配置的大小, 只要导频值存在超 过 6dB的抖动, 就会引发 UE在非干扰带和干扰带之间频繁调整, 进 而引发 UE在不同频点中的频繁调整, 而该频繁调整一方面会增加掉 话率, 另一方面会影响到临小区中用户的业务质量;
2、 FDCA算法定时器仅通过设置该定时器时长来控制载频调整 的次数:有可能在该定时器时长设置过长时,阻止了必要的载频调整。
总之, 迫切需要本领域技术人员解决的一个技术问题就是: 如何 能够更好地控制载频调整。 发明内容
本发明实施例所要解决的技术问题是,提供一种载频调整方法和 系统, 用以更好地控制载频调整, 从而降低掉话率, 提高用户体验。
为了解决上述问题, 本发明实施例公开了一种载频调整方法, 包 括:
配置惩罚定时器参数, 所述参数包括惩罚时长、 惩罚值初始值; 启动惩罚定时器;
在该惩罚定时器超时前, 根据 UE 源区域的当前惩罚值和当前 UE上报的导频值, 判断该 UE是否跨区域, 若是, 则触发从 UE源 区域载频到 UE目标区域载频的调整, 并更新 UE目标区域的当前惩 罚值; 其中, UE源区域惩罚值和 UE目标区域惩罚值的初始值等于 所述惩罚值初始值。
优选的, 所述根据 UE源区域的当前惩罚值和当前 UE上报的导 频值, 判断该 UE是否跨区域的步骤, 包括:
在 UE源区域为 UE非干扰带时, 根据 UE非干扰带的当前惩罚 值和当前 UE上报的导频值, 判断该 UE是否跨区域, 若是, 则触发 从 UE非干扰带载频到 UE干扰带载频的调整, 并更新 UE干扰带的 当前惩罚值;
或者,

具体实施方式
为使本发明的上述目的、特征和优点能够更加明显易懂, 下面结 合附图和具体实施方式对本发明作进一步详细的说明。 参照图 2, 示出了本发明一种载频调整方法实施例 1的流程图, 具体可以包括:
步骤 201、 配置惩罚定时器参数, 所述参数可以包括惩罚时长、 惩罚值初始值;
步骤 202、 启动惩罚定时器;
步骤 203、 在该惩罚定时器超时前, 根据 UE源区域的当前惩罚 值和当前 UE上报的导频值, 判断该 UE是否跨区域, 若是, 则触发 从 UE源区域载频到 UE目标区域载频的调整, 并更新 UE目标区域 的当前惩罚值; 其中, UE源区域惩罚值和 UE目标区域惩罚值的初 始值等于所述惩罚值初始值。
本发明实施例引入惩罚定时器的概念,使得载频调整不再仅仅取 决于用户上报的导频值; 这样, 在短时间内 UE所处当前小区导频值 存在数次幅度大于 6dB 的抖动时, 可以适当调整该惩罚定时器的策 略, 以限制 UE在不同频点中的频繁调整; 例如, 所述策略可以为: 通过不断更新惩罚值参数来最终停止载频调整, 限制载频调整次数,
从而降低掉话率, 提高用户体验。
或者, 即使在惩罚定时器未超时的情况下, 如果 UE所处当前小 区导频值大幅恶化(例如 12dB ), 仍然可以进行载频调整, 因而, 本 发明实施例不会阻止必要的载频调整,从而在很大程度上防止掉话的 发生。 参照图 3, 示出了本发明一种载频调整方法实施例 2的流程图, 具体可以包括:
步骤 301、 配置惩罚定时器参数, 所述参数可以包括惩罚时长、 惩罚值初始值;
步骤 302、 启动惩罚定时器;
本发明实施例可以应用于各种上报 RSCP值且可以采用 FODCA 算法的移动通信系统, 如 TD-SCDMA系统、 WCDMA (宽带码分多 址, Wideband Code Division Multiple Access ) 系统等, 下面仅仅以 TD-SCDMA系统为例进行说明, 其它移动通信系统请参照即可。
在 TD-SCDMA中, RNC通常根据小区内 UE上报的 FO (频率 优化, Frequency Optimization ) 测量报告, 制定该小区的 FODC A策 略。
例如, RNC通过观测该 FO测量报告中的本小区 PCCPCH RSCP 值, 发现该 PCCPCH RSCP值在短时间内存在数次幅度大于 6dB的 抖动, 则 RNC可以考虑在 FODCA策略中利用惩罚定时器。
关于启动惩罚定时器的时机,一般是在 UE的某次载频调整完成 后; 也即, 在 RNC成功收到 UE回复的重配置完成后, 启动惩罚定 时器。
步骤 303、 在该惩罚定时器超时前, 若 UE源区域为 UE非干扰 带, 则根据 UE非干扰带的当前惩罚值和当前 UE上报的导频值, 判
断该 UE是否跨区域, 若是, 则触发从 UE非干扰带载频到 UE干扰 带载频的调整, 并更新 UE干扰带的当前惩罚值, 其中, UE源区域 惩罚值和 UE目标区域惩罚值的初始值等于所述惩罚值初始值;
根据载频调整方向, 可以将本发明的载频调整分为两种: 从 UE 非干扰带载频到 UE干扰带载频的调整, 以及, 从 UE干扰带载频到 UE非干扰带载频的调整, 步骤 303和步骤 304分别对所述两种载频 调整进行说明。
在实际中, 根据 UE非干扰带的当前惩罚值和当前 UE上报的导 频值, 若当前 UE所在小区的任一邻区不满足如下条件:
PCCPCH_RSCPS + penaltyl - PCCPCH_RSCPAdji≥Th - ALPHA ③ 则判断当前 UE跨区域;
其中, PCCPCH_RSCPS为当前 UE所在小区的 RSCP值, penaltyl为 UE非干扰带的当前惩罚值, PCCPCH_RSCPAdji为当前 UE所在小区的 任一邻区的 RSCP 值, 预置参数 Th=3 ~ 6dB , 预置参数 ALPHA=0~3dB。
步骤 304、 在该惩罚定时器超时前, 若 UE源区域为 UE干扰带, 则根据 UE干扰带的当前惩罚值和当前 UE上报的导频值,判断该 UE 是否跨区域, 若是, 则触发从 UE干扰带载频到 UE非干扰带载频的 调整, 并更新 UE非干扰带的当前惩罚值。
在实际中, 根据 UE干扰带的当前惩罚值和当前 UE上报的导频 值, 若当前 UE所在小区的所有邻区均不满足如下条件:
PCCPCH_RSCPS - penalty2 - PCCPCH_RSCPAdji < Th + ALPHA @ 则当前 UE跨区域;
其中, penalty2为 UE干扰带的当前惩罚值。
为达到限制载频调整次数的目的, 在触发载频调整后, 本发明实
施例会进行惩罚值的更新操作。
以步骤 303为例, 由于在本次调整后, 下次调整的方向为从 UE 干扰带载频到 UE非干扰带载频的调整, 也即需要用到 UE干扰带的 当前惩罚值进行载频调整的判断, 因此, 本发明实施例选择 UE干扰 带的当前惩罚值作为所述更新操作的对象。
假设 penalty2为 UE干扰带的当前惩罚值, 在实际中, 所述针对 UE干扰带的当前惩罚值的更新操作可以为, 通过不断增加 penalty2 , 逐渐使得当前 UE所在小区的邻区均满足公式④, 最终使得当前 UE 不再具备跨区域和载频调整的条件。
在具体实现中, 可预先配置惩罚定时器的另一参数: 惩罚步长; 这样, 所述更新操作可以为, 根据所述惩罚步长, 更新 UE目标区域 的当前惩罚值。
例如,步 303的更新操作可以为, penalty2 = penalty2 + penaltyStep; 步 304的更新操作可以为 penaltyl = penaltyl+ penaltyStep;
其中, penaltyStep为惩罚步长。 另外, 为避免惩罚值过大, 导致阻止必要的载频调整的情形, 在 本发明的一种优选实施例中, 还可以设置惩罚定时器的另一参数: 惩 罚值最大值;
这样, 在每次的更新操作完成后, 还可以执行如下调整步骤: 在更新完成后, 若 UE目标区域的当前惩罚值大于该惩罚值最大 值, 则将该 UE目标区域的当前惩罚值调整为该惩罚值最大值。
由于通过调整使得 UE目标区域的当前惩罚值不会过大, 这样, 在判断是否触发载频调整时, 如果 UE所处当前小区导频值大幅恶化 (例如 12dB ), 仍然可以进行载频调整, 因而, 本发明实施例不会阻
止必要的载频调整, 从而在很大程度上防止掉话的发生。 由于 FODCA策略是针对小区制定的, 可以理解, 在该 UE调整 出当前所在小区后, RNC 可以关闭该惩罚定时器, 进而采用新的 FODCA策略, 以适应 UE所处的新环境(新小区)。
再者,在该惩罚定时器超时后,如果用户没有离开当前所在小区, RNC可以继续在 FODCA策略中利用惩罚定时器; 例如, 一旦检测 到从 UE源区域载频到 UE目标区域载频的调整,则在该调整完成后, 继续执行启动惩罚定时器的步骤;本发明对惩罚定时器的具体启动时 机不加以限制。 为使本领域技术人员更好地理解本发明,以下通过示例说明惩罚 定时器在载频调整中的应用。
该示例涉及, 配置的惩罚定时器时长为 10s, 惩罚值初始值为 2, 惩罚值最大值为 5, 惩罚步长为 1 , Th为 4, ALPHA为 3; 假设该惩 罚定时器处于未超时的情况, 参照图 4, 具体可以包括:
步骤 401、 启动惩罚定时器;
UE非干扰带惩罚值的初始值 penaltyl=2, UE干扰带惩罚值的初 始值 penalty 2=2。
步骤 402、 UE源区域为 UE干扰带,根据上报的 PCCPCH_RSCPs ( 50 )、 PCCPCH—RSCPAdjl ( 40 )和 penalty2, 得知当前 UE所在小 区的所有邻区均不满足公式④, 则触发从 UE干扰带载频到 UE非干 扰带载频的调整, 并更新 penalty 1= penalty 1+1=3;
步骤 403、 UE 源区域为 UE 非干扰带, 根据上报的 PCCPCH—RSCPs ( 50 )、 PCCPCH—RSCPAdjl ( 55 )和 penalty 1 , 得知 当前 UE所在小区的某一邻区不满足公式③, 则触发从 UE非干扰带
载频到 UE干扰带载频的调整, 并更新 penalty2= penalty2+l=3;
步骤 404、 UE源区域为 UE干扰带,根据上报的 PCCPCH_RSCPs ( 50 )、 PCCPCH—RSCPAdjl ( 40 )和 penalty2, 得知当前 UE所在小 区的所有邻区均不满足公式④, 则触发从 UE干扰带载频到 UE非干 扰带载频的调整, 并更新 penalty 1= penaltyl+l=4;
步骤 405 、 UE 源区域为 UE 非干扰带, 根据上报的 PCCPCH—RSCPs ( 50 )、 PCCPCH—RSCPAdjl ( 55 )和 penalty 1 , 得知 当前 UE所在小区的某一邻区不满足公式③, 则触发从 UE非干扰带 载频到 UE干扰带载频的调整, 并更新 penalty2= penalty2+l=4;
步骤 406、 UE源区域为 UE干扰带,根据上报的 PCCPCH_RSCPs ( 50 )、 PCCPCH_RSCPAdjl ( 40 )和 penalty2, 得知当前 UE所在小 区的某一邻区满足公式④, 则不触发载频调整;
步骤 407、 检测到该 UE调整出当前所在小区, 关闭该惩罚定时 哭口 。
可以理解, 除了当前 UE调整出当前所在小区后, 本领域技术技 术人员还可以根据 FODCA的实际需要,在其它时机关闭该惩罚定时 器, 本发明实施例对惩罚定时器的具体关闭时机不加以限制。 与前述方法实施例相应,本发明还公开了一种载频调整系统实施 例, 参照图 5, 具体可以包括:
配置模块 501 , 用于配置惩罚定时器参数, 所述参数包括惩罚时 长、 惩罚值初始值;
启动模块 502, 用于启动惩罚定时器;
判断模块 503, 用于在该惩罚定时器超时前, 根据 UE源区域的 当前惩罚值和当前 UE上报的导频值,判断该 UE是否跨区域,其中, UE源区域惩罚值的初始值等于所述惩罚值初始值;
触发模块 504, 用于在当前 UE跨区域时, 触发从 UE源区域载 频到 UE目标区域载频的调整;
更新模块 505, 用于更新 UE目标区域的当前惩罚值; 其中, UE 目标区域惩罚值的初始值等于所述惩罚值初始值。
根据载频调整方向, 可以将本发明实施例的载频调整分为两种: 从 UE非干扰带载频到 UE干扰带载频的调整, 以及, 从 UE干扰带 载频到 UE非干扰带载频的调整。
针对上述两种载频调整, 可分别对所述判断模块 503、 触发模块 504和更新模块 505做出如下设计:
A )具体而言, 在所述判断模块 503中设计:
第一判断单元 A1 ,用于在 UE源区域为 UE非干扰带时,根 据 UE非干扰带的当前惩罚值和当前 UE上报的导频值, 判断该 UE 是否跨区域; 或者,
在具体实现中, 所述第一判断单元 A1 , 可具体用于在当前 UE 所在小区的任一邻区不满足如下条件时:
PCCPCH_RSCPS + penaltyl-PCCPCH—RSCP尋≥Th - ALPHA
判断当前 UE跨区域;
其中, PCCPCH_RSCPS为当前 UE所在小区的 RSCP值, penaltyl为 UE非干扰带的当前惩罚值, PCCPCH_RSCPAdji为当前 UE所在小区的 任一邻区的 RSCP值, 预置参数 Th=3 ~ 6dB , 预置参数 ALPHA= 0~3dB。
第二判断单元 A2,用于在 UE源区域为 UE干扰带时,根据 UE干扰带的当前惩罚值和当前 UE上报的导频值, 判断该 UE是否 跨区域;
例如, 该第二判断单元 A2, 可具体用于在当前 UE所在小区的
所有邻区均不满足如下条件时:
PCCPCH_RSCPS - penalty2_PCCPCH_RSCP尋≥Th + ALPHA
判断当前 UE跨区域;
其中, penalty2为 UE干扰带的当前惩罚值。
B )所述触发模块 504可以包括:
第一触发单元 B1 ,用于触发从 UE非干扰带载频到 UE干扰带载 频的调整; 或者,
第二触发单元 B2,用于触发从 UE干扰带载频到 UE非干扰带载 频的调整; 并更新 UE非干扰带的当前惩罚值。
C )在所述更新模块 505中设置如下单元:
第一更新单元 C1 , 用于更新 UE干扰带的当前惩罚值; 或者, 第二更新单元 C2, 用于更新 UE非干扰带的当前惩罚值。
在实际中, 上述单元结构的配合可以包括: 对应从 UE非干扰带 载频到 UE干扰带载频的调整, 第一判断单元 Al、 第一触发单元 B1 和第一更新单元 C1配合工作; 或者, 对应从 UE干扰带载频到 UE 非干扰带载频的调整,第二判断单元 A2、第二触发单元 B2和第二更 新单元 C2配合工作; 在具体实现中, 可预先配置惩罚定时器的另一参数: 惩罚步长; 这样, 所述更新模块 505, 可具体用于根据预置惩罚步长, 更新 UE 目标区域的当前惩罚值。
另外, 为避免惩罚值过大, 导致阻止必要的载频调整的情形, 在 本发明的一种优选实施例中, 还可以设置惩罚定时器的另一参数: 惩 罚值最大值;
这样, 所述系统还可以包括:
惩罚值调整模块, 用于在更新完成后, 若 UE目标区域的当前惩
罚值大于该惩罚值最大值, 则将该 UE目标区域的当前惩罚值调整为 该惩罚值最大值。
再者, 由于 FODCA策略是针对小区制定的, 可以理解, 还可以 所述系统中设计一关闭模块, 其可用于在该 UE调整出当前所在小区 后, 关闭该惩罚定时器。
再者,在该惩罚定时器超时后,如果用户没有离开当前所在小区, RNC可以继续在 FODCA策略中利用惩罚定时器; 故可以在所述系 统中设计一检测模块, 其可用于在该惩罚定时器超时后, 如果检测到 从 UE源区域载频到 UE目标区域载频的调整, 则在该调整完成后通 知所述启动模块进行启动惩罚定时器的操作。
