A method of rapidly determining the transmission time and range of a position message under an Internet virtual reality environment is employs a timer scheme for updating the virtual reality environment by using a timer to count a time value. A virtual scene is divided into plural blocks. A block where a user is in and blocks neighboring to the block are defined as a low interactive area of interest, which is divided into plural sub-blocks. A sub-block where the user is in and sub-blocks neighboring to the sub-block are defined as a high interactive area of interest. A message is transmitted to update the virtual reality environment based on different settings of the low interactive area of interest and the high interactive area of interest when the timer is up and the virtual reality environment reaches a predetermined inconsistency, wherein the time value for the high interactive area is shorter than that for the low interactive area.
