Disaster and emergency mode for mobile radio phones
View Patent ↗A method and device are provided for allowing an efficient control of the establishment of connections of mobile radio phones that are present in an area hit by a disaster. According to the present invention, a sequence is transmitted in a single broadcast to all mobile stations in at least one cell of a mobile radio network present in the respective area. According to the sequence, a connection to a mobile station in the area is only established if the mobile station requesting establishment of the connection communicates the sequence when requesting establishment of the connection.
1. A method for controlling establishment of connections to mobile stations present in an area, the method comprising:
transmitting a sequence in a message sent to the mobile stations in at least one cell of a mobile radio network present in the area; and
providing that a voice connection only be established from a mobile station in the area to a destination called by the mobile station when the mobile station requesting the voice connection establishment communicates the sequence, and
a telephone number of a subscriber, which a mobile station may call during a disaster, consists of the sequence and at least one of at least part of a device number of the mobile station and a subscriber ID number of the mobile station.
2. The method for controlling establishment of connections to mobile stations as claimed in claim 1 , the sequence transmitted as a cell broadcast short message.
3. The method for controlling establishment of connections of mobile stations as claimed in claim 1 , the sequence transmitted as a circuit switched group call.
4. The method for controlling establishment of connections of mobile stations as claimed in claim 1 , the transmission of the sequence accomplished via an SIM application toolkit of the mobile station, the SIM application toolkit prompting the mobile station to transmit data representing at least one of a telephone number of the mobile station and a terminal number of the mobile station to one of the mobile radio network and the destination.
5. The method for controlling establishment of connections of mobile stations as claimed in claim 1 , further comprising scanning at least one of telephone numbers and mobile station device numbers of the mobile stations in the area to substantially ascertain which of the mobile stations are present in the area.
6. A switching device for controlling establishment of a connection to mobile stations present in an area, comprising:
a transmitting apparatus for transmitting a sequence in a message sent to the mobile stations in at least one cell of a mobile radio network present in the area; and
a receiving apparatus for receiving the sequence with a request for establishment of a voice connection to a destination from a mobile station in an area of a disaster, wherein the voice connection requested from the mobile station will be established to the destination when the mobile station can specify the sequence and the destination is identified by a telephone number comprising the sequence, and at least one of at least part of a device number of the mobile station and a subscriber ID number of the mobile station.
7. The switching device of claim 6 , the sequence transmitted as a cell broadcast short message.
8. The switching device of claim 6 , the sequence transmitted as a circuit switched group call.
9. The switching device of claim 6 , comprising a scanning apparatus to scan for at least one of telephone numbers and mobile station device numbers of the mobile stations in the area to substantially ascertain which of the mobile stations are present in the area.
10. The switching device of claim 6 , the transmitting apparatus transmitting the sequence accomplished via an SIM application toolkit of the mobile station, the SIM application toolkit prompting the mobile station to transmit data representing at least one of a telephone number of the mobile station and a terminal number of the mobile station to one of the mobile radio network and the destination.
11. A mobile station for controlling establishment of a connection from an area, comprising:
a receiving apparatus for receiving, in an area of a disaster in which the mobile station is present, a sequence, wherein the sequence is received in a message sent to the mobile station in at least one cell of a mobile radio network present in the area; and
a transmitting apparatus for transmitting the sequence with a request for establishment of a voice connection to a destination to the mobile radio network, wherein the voice connection will be established to the destination when the mobile station can specify the sequence and the destination is identified by a telephone number comprising the sequence, and at least one of at least part of a device number of the mobile station and a subscriber ID number of the mobile station.
12. The mobile station of claim 1 , the sequence received as a cell broadcast short message.
13. The mobile station of claim 11 , the sequence received as a circuit switched group call.
14. The mobile device of claim 11 , the receiving apparatus receiving the sequence accomplished via an SIM application toolkit of the mobile station, the SIM application toolkit prompting the mobile station to transmit data representing at least one of a telephone number of the mobile station and a terminal number of the mobile station to one of the mobile radio network and the destination.
