Various techniques are provided which may be implemented as methods, apparatuses and articles of manufacture for use by a mobile device. In certain example implementations, a mobile device may process a barometric pressure measurement indicative of an altitude effect and a weather effect to determine a first parameter corresponding to the altitude effect and a second parameter corresponding to the weather. Such a mobile device may further determine whether it may be transitioning or may have transitioned from an initial level to another level of a multiple level structure based, at least in part, on the first and second parameters. 本发明提供可实施为供移动装置使用的方法、设备和制品的各种技术。在某些实例实施方案中，移动装置可以处理指示海拔高度效应和气候效应的气压测量值以确定对应于所述海拔高度效应的第参数和对应于所述气候的第二参数。此类移动装置可以进步至少部分地基于所述第参数和所述第二参数确定其可能正在从多层级结构的初始层级转移到另层级还是可能已经从所述多层级结构的所述初始层级转移到所述另层级。
