用于以低功耗接收地理栅栏服务的电子装置和方法
摘要：
提供了一种用于以低功耗接收地理栅栏服务的电子装置和方法。一种供接收地理栅栏服务的电子装置使用的方法确定使用蜂窝定位系统（CPS）确定的电子装置的当前位置是否位于离地理栅栏服务区的中心点的第一距离内。响应于确定当前位置位于第一距离内，使用Wi‑Fi定位系统（WPS）来确定当前位置，并且进一步确定WPS确定的当前位置是否位于离地理栅栏服务区的中心点的第二距离内。响应于确定当前位置位于第二距离内，确定使用全球定位系统（GPS）计算的当前位置是否位于地理栅栏服务区的边界内。
摘要（英）：

A method used by an electronic device 101 receiving a geo-fence service, determines whether a current position of the electronic device, determined using a cellular positioning system (CPS), is located within a first distance 103 from a central point of a geo-fence service area 102. In response to determining that the current position is located within the first distance 103, the current position is determined using a Wi-Fi positioning system (WPS) and it is further determined whether the WPS determined current position is located within a second distance 104 from the central point of the geo-fence service area. In response to the determination the current position is located within the second distance 104, it is determined whether the current position calculated using a global positioning system (GPS), is located within a boundary of a geo-fence service area 102.
