It is again introduced into TA5 at time point 3:UE, obtains the system time of current network element device also It is 1234569000 by update of time stamp.Current timestamp is used to deduct timestamp formerly: 1234569000-1234568000=1000, by 1000 results obtained divided by 2 backward upper round numbers It is 500.

So, obtain at the TA LIST1 of time point 3 be:

The TA5 persistent period measures as 1+500=501

The TA1 persistent period measures as 1+55=56

It is 500 that the TA2 persistent period measures

It is 50 that the TA3 persistent period measures

It is 50 that the TA4 persistent period measures

The timestamp of TA LIST1 is: 1234569000

It is re-introduced into TA1 at time point 4:UE, obtains the system time of current network element device And by update of time stamp be timestamp be 1234569100, use current timestamp to deduct formerly Timestamp: 1234569100-1234569000=100, obtains 100 divided by 2 backward upper round numbers Result be 50.

So, obtain at the TA LIST1 of time point 4 be:

It is 1 that the TA1 persistent period measures

The TA5 persistent period measures as 501+50=551

It is 500 that the TA2 persistent period measures

It is 50 that the TA3 persistent period measures

It is 50 that the TA4 persistent period measures

The timestamp of TA LIST1 is: 1234569100
