背景技术
现代的无线通讯领域在原有的大基站(宏站)、规划组网基础上,对分布式、小基站(微站)组网的需求也在不断的增加。小基站分布式组网日益成为规划组网必不可少的补充。
分布式小基站带来了用户体验上升、基站建设快速、方便等等的优点,但也带来一些问题。宏微组网通过手动配置邻区的基站类型是不现实的,因为首先,微站本身的地理位置具有不确定性;其次,微站如果部署,其数量密度和宏站的数量密度不是一个数量级,手动配置可能导致维护成本急剧上升。所以宏微自组织组网是必须的。
宏站和微站信令面对MME(Mobility Management Entity,移动管理实体)的接口S1,使用的基站标识(eNB ID)是有严格区分基站的类型的,但空口的协议(36331)则无法区分基站类型。LTE S1/X2协议(36413,36423)描述的Global eNB ID格式如下表1所示:
Figure PCTCN2015076662-appb-000001
Figure PCTCN2015076662-appb-000002
表1
如果宏微基站无法正确判断邻区基站类型,将导致自组织网络无法实现或者存在诸多缺陷和其他移动性问题。例如基站通过ANR(Automatic Neighbor Relation,自动邻区关系)自配置的邻区,在无法知道目标站类型的情况下将无法进行切换和X2自建立的过程,进而影响更多基于移动性和X2的功能。
在宏站和微站共存的网络里,站与站之间无法通过空口的信令获知邻站的类型,从而导致一些LTE原有的自组织网络(self-organizing networks,SON)功能和移动性无法很好的实现。
