Abstract: Methods and apparatus for processing positioning assistance data are provided. An exemplary method includes receiving, from a positioning server, virtual access point (VAP) data including a list of unique identifiers, and determining a location of a mobile device by using the VAP. The VAP data indicates that the unique identifiers included on the list identify signals originating from the same physical access point. The unique identifiers can be MAC addresses. In an example, the location determining the can include actively scanning a signal identified by a unique identifier on the list and not actively scanning a different signal identified by a different unique identifier also on the list. Not scanning the other MAC addresses that are on the access point's list and assigned to the mobile device keeps the mobile device from performing duplicative scanning that wastes time, processor cycles, and energy.
Abstract translation: 提供了用于处理定位辅助数据的方法和装置。 一种示例性方法包括从定位服务器接收包括唯一标识符的列表的虚拟接入点（VAP）数据，以及通过使用VAP来确定移动设备的位置。 VAP数据指示列表中包括的唯一标识符识别源自相同物理接入点的信号。 唯一标识符可以是MAC地址。 在一个示例中，确定该位置的位置可以包括主动地扫描由列表上的唯一标识符标识的信号，而不主动地扫描由列表上的不同唯一标识符标识的不同信号。 不扫描接入点列表上分配给移动设备的其他MAC地址会使移动设备不会执行浪费时间，处理器周期和能量的重复扫描。
