| 摘要 | Identifying geographic stationarity of a mobile device may be achieved by determining whether the mobile device is engaged in high average velocity movement based on radio frequency (RF) environment variation estimation, determining whether the mobile device is engaged in low average velocity movement based on pedestrial stepping information, and declaring a stationary state for the mobile device based on an absence of high and low average velocity movement. | ||

| 主权项 | 1. A method of identifying geographic stationarity of a mobile device, comprising: determining whether the mobile device is engaged in high average velocity movement based on a radio frequency (RF) environment variation estimation; determining whether the mobile device is engaged in low average velocity movement based on pedestrial stepping information; and declaring a stationary state for the mobile device based on the high and low average velocity movement determinations indicating an absence of high and low average velocity movement. | ||
