Abstract

A flexible mobile base station is disclosed comprising a configurable wireless jamming unit, a configurable transceiver, a wireless spectrum analyzing unit, a processing unit and a wireless channels database.

Claims

1. A method of assigning a wireless channel for communication between a base station and a mobile device comprising:

scanning a plurality of wireless channels;

identifying active wireless channels within said plurality of wireless communication channels;

in a database, assigning an active status to each one of said active wireless channels; and

configuring said base station to communicate with said mobile device on one of said wireless channels other than those to which an active status is assigned.

2. The method as claimed in claim 1, further comprising jamming said active wireless channels.

3. The method as claimed in claim 2, wherein said active wireless channels comprise a plurality of wireless communication channels and at least one wireless control channel, further wherein said jamming is performed on said at least one wireless control channel.

4. A method for communicating between a plurality of mobile devices capable of communicating on a plurality of wireless communication channels using a configurable wireless transceiver, said method comprising:

selecting a wireless communication channel from said plurality for communicating with a mobile device of the plurality of mobile devices;

checking if said selected wireless communication channel is a non-active wireless communication channel by accessing a database comprising a list of active wireless communication channels;

if said checking is unsuccessful, reselecting a wireless communication channel;

if said checking is successful, configuring said configurable wireless transceiver using said selected wireless communication channel and communicating with said mobile device using said configured wireless transceiver.

5. The method as claimed in claim 4, further comprising scanning a predetermined list of wireless communication channels to identify a list of non-active wireless communication channels and a list of active wireless communication channels and building said database comprising said list of active wireless communication channels.

6. The method as claimed in claim 5, further comprising jamming each of said active wireless communication channels.

7. The method as claimed in claim 6, wherein said scanning comprises measuring an indication of a power level for each of said active wireless communication channel, further wherein each of said indication of a power level for each of said active wireless communication channels is stored in said database, wherein said jamming is performed at a power level substantially equal to said indication of said power level.

8. The method as claimed in claim 4, wherein said communicating with said mobile device using said configured wireless transceiver comprises sending a message to shut-down said mobile device.

9. The method as claimed in claim 8, wherein said message to shut-down said mobile device comprises at least one of a recorded voice message and a SMS message.

10. A method for providing a virtual home base station to a mobile device communicating on an access provider wireless communication channel using a configurable wireless transceiver, comprising:

identifying at least one parameter of an access provider operating the mobile device on the access provider wireless communication channel;

configuring the configurable wireless transceiver to communicate with the mobile device using the at least one parameter of the access provider operating the mobile device on the access provider wireless communication channel and a suitable wireless communication channel; and

jamming the access provider wireless communication channel.

11. The method as claimed in claim 10, wherein a plurality of virtual home base stations are provided to a plurality of mobile devices, each of said mobile devices communicating on an access provider wireless communication channel.
