SELECTIVELY PERFORMING A POSITIONING PROCEDURE AT AN ACCESS TERMINAL BASED ON A BEHAVIOR MODEL

摘要

In an embodiment, an access terminal (AT) (200; 900) measures (415) and reports (420) location information when positioned at a user-defined place associated with a geofence to a server (170; 900), and the server updates (425) a place fingerprint configured to identify the user-defined place based on the reported location information. In another embodiment, the AT or the server obtains (505A; 505E) location information associated with a set of user-defined places that are identifiable by a set of place fingerprints, determines (510A; 525A; 500B, 505B, 510B; 505C, 510C, 515C, 520C, 525C, 530C; 505E; 515E) whether a location event has occurred and updates (510A; 525A; 505E; 515E) a behavior model for the access terminal based on the determination. In another embodiment, the AT receives (700) a request for its location and evaluates (705, 715; 705, 715, 720, 725; 810A, 815A) a set of factors (e.g., the behavior model, etc.) to determine whether to acquire the ATs location with a high power-consumption positioning procedure (e.g., GPS).
