The present invention relates to a context awareness service technique. Particularly, since a method for inferring a movement section of a subway based on context awareness extracts the movement section of the subway from a moving path formed by connecting in sequence coordinates of points measured with a constant time interval according as a user moves, comparative high probability and correct inference can be achieved in a vehicle line and a driving route, an inference error due to non load of a wireless access device in a section of the subway can be reduced, and a consumed current gain can be enhanced. Additionally, dependency on a wireless access method is high due to an error of mobile communication cell information in conventional technique, but the method can realize a cell based inference reinforcement through a solution of a cell cash problem. The method comprises the steps of: extracting a plurality of inference factor information by analyzing plural sensing information measured at each of the coordinates; giving an inference score by verifying the inference factor information according to preset inference reference; summating the inference scores corresponding to the coordinates and obtaining a plurality of coordinates with an inference score more than a critical value based on the summating; and inferring a section formed by sequential coordinates with the inference score more than the critical value of the moving path as the movement section of the subway. |
