摘要： The location of a mobile terminal may be determined in response to signals received from a plurality of RFIDs. Information from a plurality of RFIDs for determining a location of a mobile terminal is received by the mobile terminal. The mobile terminal may maintain an in-range list that comprises all the RFIDs in which the mobile terminal is currently within their coverage range. The location of the mobile terminal is calculated in response to the received information for determining a location by calculating the common coverage area of the RFIDs in the in-range list.

摘要翻译： 可以响应于从多个RFID接收到的信号来确定移动终端的位置。 来自用于确定移动终端的位置的多个RFID的信息被移动终端接收。 移动终端可以保持包括移动终端当前在其覆盖范围内的所有RFID的范围内列表。 通过计算在范围列表中的RFID的公共覆盖区域，响应于接收到的用于确定位置的信息来计算移动终端的位置。
