Step 304: it is short measurement period T that the nearby region measurement cycle is set
short, T
measure=T
short, flow process finishes.

wait=T
wait– 1, flow process finishes.
That is to say, the stand-by period is not when overtime, the stand-by period subtracted to the result obtaining after 1 as the new stand-by period, until the stand-by period is overtime.
Step 404: judge whether cell reselection assessment has candidate adjacent, if there is no candidate adjacent, performs step 405, if there is candidate adjacent, flow process finishes.
Step 405: be set for long measurement period T the nearby region measurement cycle
