Method of measuring variance of data payload in wireless communications system and related apparatus

摘要

In order to prevent traffic volume measurement errors, especially variance measurement errors, the present invention provides a method of measuring variance of a data payload in a wireless communications system. The method includes the following steps. Plural variance reference values are predetermined (302). A variance measurement result related to data payload is received (304). If the variance measurement result is greater than the plural variance reference values, the variance measurement result is rounded downwards to the maximum variance reference value of the plural variance reference values (306). Preferably, the plural variance reference values have a maximum value of 16K and a minimum value of 0, where K is 1024. The plural variance reference values other than the minimum value form a geometric sequence.
