automatic neighbor relation
自动邻区关系
Automatic neighbor relation (ANR) is a feature by which a UE reports a new neighbor relationship to the network so that the network can maintain a neighbor cell list for that particular cell. In a typical cell reselection case, the UE can report new neighbor relations between the new serving cell and the old serving cell only when the new serving cell belongs to the selected PLMN or one of the equivalent PLMNs for the UE, and is not barred or reserved for operator use.
在 LTE (Long Term Evolution, 长期演进) 系统中，自动邻区关系 ANR (Automatic Neighbor Relation , 自动邻区关系) 是SON (Self-Organizing Network, 自组织网络) 功能的重要组成部分，该功能为从UE处获取必要的测量信息，实现邻区关系的配置自动化。当UE测量上报未知小区(没有和服务小区配置邻区关系的小区)，是否将该未知小区自动配置为服务小区的邻区可以依据算法策略参考若干指标，其中信号质量是重要的参考指标之一，该指标可以优化ANR功能配置的服务小区的邻区关系。"
