METHOD, APPARATUS AND SYSTEM FOR NETWORK RESOURCE RESERVATION BASED ON MOVING SPEED OF MOBILE TERMINAL, AND MOBILE TERMINAL THEREFOR
First Claim
1. A method for network resource reservation based on a moving speed of a mobile terminal, the method comprising:
- receiving a request for network resource reservation from the mobile terminal;
calculating an expected moving direction of the mobile terminal, based on a speed-based moving probability model represented by a probability density function for a movable direction dependent on the moving speed of the mobile terminal, the moving speed of the mobile terminal, and position information of the mobile terminal; and
performing network resource reservation for wireless cells included in the calculated expected moving direction.

Abstract
The present invention relates to a method, apparatus and system for network resource reservation and a mobile terminal therefor. Provided are a method, apparatus and system for minimizing unnecessary network resource reservation by predicting an expected direction of a terminal. The method for network resource reservation based on a moving speed of a mobile terminal includes: receiving a request for network resource reservation from the mobile terminal; calculating an expected moving direction of the mobile terminal, based on a speed-based moving probability model represented by a probability density function for a movable direction dependent on the moving speed of the mobile terminal, a moving speed of the mobile terminal, and position information of the mobile terminal; and performing network resource reservation for wireless cells included in the calculated expected moving direction. Thus, unnecessary network resource reservation can be minimized by predicting the moving direction of the terminal.
