The invention discloses a statistics method of single user downloading rates in busy time, including: dividing a busy time frame into more than two time frames of a same length through time quantum nodes; extracting a charging intermediate bag with the time frames of a same length as time intervals; and determining a charging bag combination type before and after the time quantum nodes, and obtaining single user downloading rates in busy time corresponding with the time quantum nodes according to a compute mode corresponding with the charging bag combination type. The invention also provides a statistics apparatus of single user downloading rates in busy time.
