Patent ID: 8725169

Claim:
A method for determining a mobility state of a terminal, comprising: a base station calculating a total moving distance of a terminal in a predetermined period by using a distance estimation strategy; and the base station determining a mobility state of the terminal according to the total moving distance, wherein the distance estimation strategy comprises: when a type of a present serving cell is a first power cell, and a type of a previous serving cell is the first power cell and a type of a serving cell before the previous serving cell is also the first power cell, using a diameter of the previous serving cell as the moving distance of the terminal resulting from the estimation at this time; otherwise, skipping the estimation of the moving distance at this time; when the type of the present serving cell is a second power cell, using a distance between a center of the present serving cell and a center of the previous serving cell as the moving distance of the terminal resulting from the estimation at this time; wherein power of the first power cell is higher than power of the second power cell.
