DNS Query的问题

DNS Query的具体细节我不懂，分析不了具体啥意思，

I have tested DNS query Cause procedure. I have tried many times, SGSN shall query DNS every 1 min (TimeToLive 60sec) and SGSN is acting accordingly (doesn’t query DNS within one minute from the last query). Despite this UBAS is reporting as if SGSN is querying the SGSN in those intervals (less than 1min).You can compare it with the SGSN trace where only three DNS queries/answers are visible whereas in UBAS in the same time six events are recorded.

局方反馈的问题，意思就是说DNS Query ,频率间隔最少1分钟？
