MOBILE DEVICE LOCATION BY MEANS OF FUZZY LOGIC |
摘要 |
A mobile device (204) may be located through an application programming interface (API) (222). The API (222) procedures interact with a server (206) of a carrier (226) having carrier based methods of identifying the device (204). The location of the device (204) may then be refined using fuzzy logic. Imprecise input (702) is processed to determine a magnitude of participation in a rule base (706). The rules in the rule base (706) are applied based on the magnitude to produce a logical product that is used to compute a refined location. Further, a user's profile information (228-230) in an external database may be location enabled. A schema definition (234) having the user's profile information (228-230), data source information, an SQL statement that extracts properties from a database, a foreign key, and positional information are stored in a database. Access to the stored information is then provided. |
