Security systems for providing mobile device feature access control
First Claim
1. A mobile communication unit having at least one operating mode, the mobile communication unit comprising:
- a security unit for enabling or disabling the at least one operating mode, where the security unit temporarily disables the at least one operating mode for the user of the mobile communication system;
a communication interface for receiving an enabling code from a checkpoint, a first part of the enabling code being communicated to the mobile communication unit in one communication and a second part of the enabling code being communicated in another communication; and
a mobile device storage unit for storing the second part of an enabling code when the at least one operating mode is disabled;
the security unit being configured to combine the first part and the second part of the enabling code to permit re-enabling of the at least one operating mode when the mobile communication unit receives the first part of the enabling code.

Abstract
A mobile communication unit having at least one operating mode comprising a security unit for enabling/disabling at least one operating mode, whereas the security unit is designed in such a way that at least one operating mode is temporarily disabled for the user of the mobile communication system. A checkpoint communicating unit may be used to control the operating mode of the mobile communication unit. The checkpoint communicating unit may include a status extracting unit for generating a request for a security status of the operating mode or operating modes of the mobile communication unit. The checkpoint may also include a lookup table containing at least the operating mode or operating modes to be disabled in the mobile communication unit. A comparison unit may be provided for comparing the security status received from the mobile communication unit to the disabling status stored in the lookup table.

7. A checkpoint communication unit for controlling the operating mode of a mobile communication unit, the checkpoint communication unit comprising:
-
a status extracting unit for generating a request for a security status of at least one operating mode of the mobile communication unit; a look up table containing at least one operating mode to be disabled and a disabling status for the at least one operating mode to be disabled; a checkpoint storage unit for storing a first part of an enabling code when the at least one operating mode is disabled, the checkpoint communication unit being configured to send the second part of the enabling code to the mobile communication unit when the at least one operating mode is disabled and to send the first part of the enabling code when the at least one operating mode is re-enabled; a comparison unit for comparing the security status received from the mobile communication unit to the disabling status stored in the look up table; and a command generating unit for generating a disabling command for the mobile communication unit when the security status of the communication unit comprises the information that one operating mode to be disabled is enabled at the mobile communication unit. - View Dependent Claims (8, 9)

10. A method for controlling an operating mode of a mobile communication unit, the mobile communication unit comprising at least one operating mode, the method:
-
detecting the mobile communication unit in a restricted area; receiving a disabling/enabling status of the operating mode from the mobile communication unit; generating a disabling command indicating the operating mode to be disabled and an enabling code having a first part and a second part if the disabling/enabling status of the operating mode indicates that the operating mode is to be disabled in the restricted area; storing the first part of the enabling code in a storage unit; sending the disabling command and the second part of the enabling code to the mobile communication unit; and sending the first part of the enabling code to the mobile communication unit when the mobile communication unit has exited the restricted area. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method for controlling an operating mode of a mobile communication unit, the mobile communication unit having at least one operating mode, the method comprising:
-
detecting a checkpoint at a restricted area; sending a disabling/enabling status of the at least one operating mode to the checkpoint; receiving a disabling command for selected ones of the at least one operating mode and a first part of at least one enabling code having a first part and a second part, the second part being stored in the checkpoint; disabling the selected ones of the at least one operating mode; storing the first part of the enabling code in a storage unit in the mobile communication unit; receiving the second part of the enabling code; and combining the first part and the second part of the enabling code to re-enable the selected ones of the at least one operating mode. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30)
