2、邻区（双锚点场景NSA架构下已完成5-4邻区关系维护，单锚点场景需要重点关注）；规划后的邻区信息传递给电信侧，通知其完成4-SA的频点、邻区和互操作配置。2.NR侧添加4G频点和邻区关键点：1.合理设置不同频点的重选优先级、连接态优先级和VOLTE优先级2.NR SIB5消息最多携带联通+电信共8个LTE频点，各地市根据本地网实际情况进行分配并设置3.NR侧配置4G频点对应的各类优先级，建议只使用0-5，6-7暂时保留/添加联通4G频点ADD NRCELLEUTRANNFREQ:NRCELLID=x,DLEARFCN=1650,EUTRANFREQRESELPRIORITY=5,MEASURE
