Description

基于自动邻区关系的小区功率调整方法及装置、 基站 技术领域
本发明涉及灾难告警发布技术， 尤其涉及一种基于自动邻区关系的小 区功率调整方法及装置、 基站。 背景技术
地震海嘯告警系统（ ETWS , Earthquake and Tsunami Warning System ) 能为面临地震海嘯等灾害而需疏散的移动终端用户发送告警通知， 接收到 告警通知的移动终端用户能够知道危险正在来临或者已发生， 用户可以根 据告警通知确定什么时候以及向哪里疏散等， ETWS 就是来帮助人们避免 灾难或者减少灾难所带来的损失的。告警消息一般由移动管理网元（MME, Mobility Management Entity )通知给基站（ eNB, eNB ), 再由 eNB下发给 移动终端用户。
eNB要为自身所属小的区建立维护邻区关系表( NRT , Neighbor Relation Table ), 并获取自动邻区关系 （ ANR, Automatic Neighbour Relation ), 其目 标就是自动地建立和维护邻区关系表， 通过下行测量配置命令将配置信息 发送给用户设备 ( UE, User Equipment ), 并且在 eNB的邻区检测模块接收 UE的测量报告， 发现新邻区并获取邻区的必要信息。
eNB 的小区功率调整， 一般都是通过操作管理控制平台配置完成的， 这种配置是人工方式的配置， 而且配置完成后， 基本上是固定不变的。 同 时， 基于网络优化和减少对邻区干扰的考虑， 一般小区配置的实际发射功 率要远远小于小区支持的最大发射功率。
当地震或海嘯等自然灾害来临时， 虽然一些 eNB接收到了 ETWS告警 消息， 但是在地震或者海嘯中有些基站可能会受损而无法工作， 这些受损 基站所覆盖的范围将无法接入用户， 而未受损的基站可能由于小区功率配 置较小， 并且未能动态地调整小区的实际发射功率， 导致未受损基站小区 未能覆盖受损基站的覆盖范围， 导致受损基站覆盖范围的用户不能及时接 收到告警消息， 无从获知紧急信息如逃生信息等。 发明内容
有鉴于此， 本发明的主要目的在于提供一种基于自动邻区关系的小区 功率调整方法及装置、 基站， 能在地震、 海嘯或火灾等自然灾害来临或发 生时，及时通知 UE用户进行逃生自救等， 能以最大范围的覆盖通知尽可能 多的 UE用户。
为达到上述目的， 本发明的技术方案是这样实现的：
一种基于自动邻区关系的小区功率调整方法， 包括：
基站侧接收到紧急告警消息后进行自动邻区关系检测， 未能检测到有 效的邻区信息时， 调整自身的发射功率。
优选地， 所述调整自身的发射功率后， 所述方法还包括：
所述基站侧继续进行自动邻区关系检测， 并确定当前的发射功率是否 达到所述基站侧的最大发射功率； 检测到有效的邻区信息， 或确定当前的 发射功率达到所述基站侧的最大发射功率时， 结束当前处理； 未检测到有 效的邻区信息且当前的发射功率未达到所述基站侧的最大发射功率时， 所 述基站侧继续调整自身的发射功率。
优选地， 所述调整自身的发射功率为：
增加所述基站侧的发射功率。
优选地， 所述增加所述基站侧的发射功率为：
以预设的步进量步进地增加所述基站侧的发射功率。
优选地， 所述紧急告警消息中承载有地震、 火灾或海嘯的告警或预警 信息， 避灾逃生信息。 一种基于自动邻区关系的小区功率调整装置， 包括： 接收单元、 检测 单元、 确定单元和调整单元， 其中：
接收单元， 配置为接收紧急告警消息；
检测单元， 配置为进行自动邻区关系检测；
确定单元， 配置为确定未能检测到有效的邻区信息时， 触发调整单元； 调整单元， 配置为调整发射机的发射功率。
优选地， 所述调整单元调整发射机的发射功率后， 触发所述检测单元 继续进行自动邻区关系检测； 所述确定单元还配置为， 确定检测到有效的 邻区信息， 或当前的发射功率达到所述基站侧的最大发射功率时， 通知所 述调整单元结束调整； 所述确定单元确定未检测到有效的邻区信息且当前 的发射功率未达到发射机的最大发射功率时， 继续触发所述调整单元调整 发射机的发射功率。

优选地， 所述调整单元还配置为， 以预设的步进量步进地增加发射机 的发射功率。
一种基站， 包括前述的基于自动邻区关系的小区功率调整装置。
本发明中， 基站侧接收到紧急告警消息后进行自动邻区关系检测， 未 能检测到有效的邻区信息时， 调整自身的发射功率； 基站侧确定自身当前 的发射功率达到预设的发射功率阈值时， 结束当前处理； 未达到预设的发 射功率阈值时， 继续进行自动邻区关系检测， 并在未检测到有效的邻区信 息时， 继续调整自身的发射功率。 这里， 基站侧调整自身的信息发射功率 为增加基站侧的发射功率。 这样， 当发生地震、 海嘯或火灾等自然灾害时， 即使部分基站受损而无法工作， 一些可以工作的基站在接收到灾害告警消 息后， 将会自动检测自动邻区关系， 当不能获取正确的邻区信息时， 即确 定相邻基站受损而无法工作， 该基站将增加自身的信号发射功率， 以尽可 能地增加自身的小区覆盖范围， 而其他的可工作基站也会试图增加自身的 小区覆盖范围， 从而基于当前能工作的基站， 将告警消息最大化地发送给
UE用户， 使这些 UE用户尽早获知告警信息， 以尽早逃生。 本发明的技术 方案能在自然灾害发生时提高未受损基站的覆盖范围， 保证更多用户的接 入， 保证受灾用户能得到有效帮助。 附图说明
