Method and apparatus for determining mobility state of terminal
First Claim
1. 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.
