Method of Determining a Location of a Mobile Device and Method of Managing a List for Use in Such a Method

摘要

The invention relates to a method of determining a location of a mobile device for use in a first communication network and a second communication network. The mobile device is camped on a cellular base station in the second communication network. According to the method, a list of records of communication units within the first and/or second communication network that are located within a predetermined geographical area is obtained. A communication unit record contains information representative of the identity of the respective communication unit, information representative of a position of the respective communication unit, and a reliability indication of the respective communication unit. Additionally, with the mobile device, communication units within the first and second communication network are detected. Finally, the location of the mobile device is detected based on the information representative of the position, the reliability indication, and an accuracy indication of the detected communication units.

主权项

1. A cellular base station comprising:
a receiver for receiving data from one or more communication units in a first communication network and/or a second communication network; a transmitter for transmitting data towards one or more communication units in the first communication network and/or the second communication network; a database for storing data including a list of communication unit information; a processor for processing data received via said receiver and/or stored in said memory, and further configured to:
receive a message from a communication unit, the message comprising the information representative of the identity of the communication unit, and information representative of the position of the communication unit;if the information representative of the identity of the communication unit relates to a communication unit for which a record is already present in the list, amend the information representative of the position of the communication unit in the list, if the position information in the list differs from the position information in the message; andif the information representative of the identity of the communication unit relates to a communication unit that is not present in the list, add a record of the communication unit to the list, including the information representative of the identity of the communication unit, and the information representative of the position of the communication unit.
