Abstract

Mobile stations communicate with a network station in a radio cell of a network via at least one radio interface. Localization of the position of the stations is carried out by the network either periodically or according to demand. To enable fast provision of localized information, the actual locations and experienced radio conditions of the stations are stored by the network. The packet data service enabled stations can be used advantageously for other methods known for other purposes, e.g. for determining received field intensity or interference level, for carrying out cell change or for activating a polling request.

Claims

1-11. -11. (cancelled)

12. A method for operating a radio communication system with packet data-capable mobile stations in which each mobile station communicates with an assigned base station via at least one radio interface within a radio cell in a network to identify locations of the mobile stations, comprising:

registering at least one mobile station in the network;

receiving a request from the network at the base station to periodically send reports from which the location of each mobile station can be determined; and

recording in the network at least one of a current location of the at least one mobile station and measurement data recorded to determine the current location of the at least one mobile station and the assigned base station.

13. A method in accordance with claim 12, further comprising determining the location of the at least one mobile station regardless of whether the at least one mobile station has a dedicated connection to the network.

14. A method in accordance with claim 13, wherein said determining includes performing at least once a procedure for changing a cell independently of whether the one of the mobile stations is actively in transmission mode or passively in idle mode.

15. A method in accordance with claim 13,

wherein said recording includes storing at least one of receive level, interference level and timing advance of the at least one mobile station, and

further comprising averaging over time the at least one of receive level, interference level and timing advance of the at least one mobile station to improve accuracy thereof.

16. A method in accordance with claim 13, wherein said determining includes performing at least once a procedure to activate the at least one mobile station by a polling request.

17. A method in accordance with claim 13, wherein said determining includes directly supplying network devices with the at least one of a current location of the at least one mobile station and measurement data stored on the network in response to a request to determine the location of the at least one mobile station.

18. A method in accordance with claim 13, further comprising accessing the at least one mobile station in a packet data service mode to determine the location of a network device.

19. A method in accordance with claim 13, further comprising creating maps to show at least one of signal field strength, interference level and network utilization based on the measurement data.

20. A method in accordance with claim 13, further comprising automatically sending from the network messages to the at least one mobile station based on stored location values if predefined trigger points are fulfilled.

21. A radio communication system with packet data service-capable mobile stations in which at least one mobile station communicates with an assigned base station via at least one radio interface within a radio cell in a network to identify locations of the mobile stations, comprising:

at least one base station, coupled to the network, to operate at least one radio cell within which the at least one mobile station communicates if required with the base station via a radio interface;

at least one network device, coupled to the network, to instruct the base station to execute on request a localization process to determine the location of the at least one mobile station; and

at least one memory device, coupled to the network, to store at least one of a current location of the at least one mobile station, receive level, interference level and timing advance of the at least one mobile station for localization thereof.

22. A storage in a communication system with packet data service-capable mobile stations in which at least one mobile station communicates with an assigned base station via at least one radio interface within a radio cell in a network to identify locations of the mobile stations, comprising:

at least one memory device, coupled to the network, to store at least one of a current location of the at least one mobile station, receive level, interference level and timing advance of the at least one mobile station for localization thereof in response to a request to determine the location of the at least one mobile station.
