Method and apparatus for deactivating mobile radio stations from the network
Method for deactivating at least one mobile station in a radio communication system, particularly in a picocell on board an aircraft in a GSM mobile radio network, where the radio communication system has a first network element, which forms a transmission/reception device for each mobile station in the radio cell, a second network element which is set up to control the first network element, and a device which is connected between the first network element and the second network element, wherein the device carries out the following steps: detection of a piece of identification information, directed at the at least one mobile station, which is transmitted from the second network element to the first network element, use of this identification information to deactivate the at least one mobile station when a deactivation signal is supplied to the device.
1. A method for deactivating at least one mobile station in a radio cell of a radio communication system, comprising:
providing a radio communication system with a first network element which forms a send/receive device for each mobile station of the radio cell, a second network element which is designed for controlling the first network element, and a device which is connected between the first network element and the second network element;
detecting a first subscriber identification information and a second subscriber identification information which are transferred during an exchange of signaling information between the at least one mobile station and a third network element, wherein the transfer path is routed via the device;
storing the detected subscriber identification information in a memory of the device, the detected subscriber identification information indicating that the at least one mobile station is logged into a network; and
deactivating the at least one mobile station logged into the network responsive to a deactivation signal triggered by an external event not caused by use of the at least one mobile station, wherein the deactivation signal is delivered to the device and, causes the at least one mobile station to regard its own subscriber identity module as invalid and prevents the at least one mobile station from transmitting radio waves.
2. The method as claimed in claim 1 , wherein the radio cell is a picocell of a GSM (Global System for Mobile Communications) mobile radio network which is situated on board an aircraft.
3. The method as claimed in claim 1 , wherein a plurality of mobile stations are combined in groups in each case and are deactivated sequentially one after the other.
4. The method as claimed in claim 1 , wherein the deactivation of the mobile station is made dependent on whether the detected subscriber identification information is contained in a list which is present in the device.
5. The method as claimed in claim 1 , wherein on detection of the first subscriber identification information a location registration message routed via the device is used, wherein the location registration message is transmitted as a response to a request by a mobile station from the third network element to the requesting mobile station.
6. The method as claimed in claim 1 , wherein on detection of the second subscriber identification information a location registration message routed via the device is used, wherein the location registration message is transmitted as a request by a mobile station to the third network element.
7. The method as claimed in claim 1 , wherein the device is hierarchically subordinated to the second network element.
8. The method as claimed in claim 1 , wherein the device and the first network element are arranged on board an aircraft.
9. The method as claimed in claim 8 , wherein the second network element and the third network element are arranged outside of the aircraft, and wherein a link routed via satellites is used for the signal transfer between the device and the second network element.
10. An apparatus for deactivating at least one mobile station in a radio cell of a radio communication system comprising:
a first network element which represents a send/receive device for each mobile station;
a second network element for controlling the first network element;
a device connected into a signaling path between the first network element and the second network element;
a first subscriber identification information detectable by the device;
a second subscriber identification information detectable by the device, wherein the first and second subscriber identification information are transferred between the at least one mobile station and a third network element; and
a memory to store the first and second subscriber identification information, the first and second subscriber identification information indicating that the at least one mobile station is logged into a network, wherein the device uses the first and second subscriber identification information to deactivate the at least one mobile station when a deactivation signal is delivered to the device, wherein the deactivation signal is triggered by an external event not caused by use of the at least one mobile station, and causes the at least one mobile station to regard its own subscriber identity module as invalid and prevents the at least one mobile station from transmitting radio waves.
11. The apparatus as claimed in claim 10 , wherein the radio cell of the radio communication system is a picocell of a GSM (Global System for Mobile Communications) mobile radio network which is situated on board an aircraft.
12. The apparatus as claimed in claim 10 , wherein in the case of a plurality of mobile stations the device combines these into groups and deactivates mobile stations of a group sequentially one after the other.
13. The apparatus as claimed in claim 12 , wherein the device makes the deactivation of a mobile station dependent on whether the detected subscriber identification information are contained in a list which is present in the device.
14. The apparatus as claimed in claim 13 , wherein the first subscriber identification information is contained in a location registration message routed via the device, which is transmitted as a response to a request by a mobile station from the third network element to the requesting mobile station.
15. The apparatus as claimed in claim 13 , wherein the second subscriber identification information is contained in a location registration message routed via the device, which is transmitted as a request by a mobile station to the third network element.
16. The apparatus as claimed in claim 10 , wherein the device is hierarchically subordinate to the second network element.
17. The apparatus as claimed in claim 10 , wherein the device and the first network element are arranged on board an aircraft.
18. The apparatus as claimed in claim 10 , wherein the second network element is arranged outside of the aircraft.
19. The apparatus as claimed in claim 10 , wherein the second network element is arranged on the ground and wherein the signal transfer between the device and the second network element is a link routed via satellites.
