针对移网流量，福建用户希望可以在 安全/会话日志 中看到eNB的位置信息，从而知道上网用户的大致位置信息。
|
|
|
|
|
|
|
|
|
|
|
|
用户会提供 【eNB IP列表】与【eNB位置信息】，并上传至TSG系统的 IP Library 中
|
|
|
|
|
|
|
|
|
|
|
|
说明：
|
|
|
|
|
|
*1、针对移网4G的eNB IP，同一核心网网源下的所有eNB IP使用内网地址的一个A段，B段不同。以福建为例，移动、联通使用10.xxx或100.xxx，电信使用7.xxx，目前福建三个运营商的eNB IP共有100多万个，暂未发现存在IP冲突。也就是说，对于移网4G，同一省内的eNB IP不冲突，但不同省市的可能存在冲突；*
|
|
|
|
|
|
*2、针对移网5G，eNB IP和SGW IP均为IPv6地址，所以不存在IP冲突的情况；*
|
|
|
|
|
|
*3、eNB的地理位置信息粒度如下：国家-省市-区县-街道-xxxx基站；*
|

[~zhangzhihan] 参见上图，福建的接入位置，是在S1-U，还是s5/s8？
