Abstract
A method, system and apparatus for maintaining a terminal profile of a mobile communication device. The system comprises a first network node operable to establish with the mobile communication device a wireless data path, to send to the mobile communication device via the wireless data path a terminal profile modification instruction and to receive from the mobile communication device via the wireless data path an acknowledgment. The terminal profile is communicated to a subscriber identity module operable to compare pending instructions to the terminal profile in order to identify and forward authorized instructions.
Claims14
A method of maintaining a terminal profile of a mobile communication device, the method comprising:
- wirelessly receiving a terminal profile modification instruction;
- modifying a terminal profile within a subscriber identity module of the mobile communication device based on the terminal profile modification instruction to set a particular bit of the terminal profile for representing that a facility to forward location information is supported or not supported by the mobile communication device;
- storing the modified terminal profile in the subscriber identity module of the mobile communication device;
- comparing a location query relative to the location of the mobile communication device to the modified terminal profile;
- and
- forwarding the location information of the mobile communication device only when it is authorized by the modified terminal profile.
A mobile communication device comprising:
- a component configured to wirelessly receive a terminal profile modification instruction;
- a component configured to modify a terminal profile within a subscriber identity module of the mobile communication device based on the terminal profile modification instruction to set a particular bit of the terminal profile for representing that a facility to forward location information is supported or not supported by the mobile communication device;
- a component configured to store the modified terminal profile in the subscriber identity module of the mobile communication device;
- a component configure to compare a location query relative to the location of the mobile communication device to the modified terminal profile;
- and
- a component configured to forward the location information of the mobile communication device only when it is authorized by the modified terminal profile.
A network node adapted to maintain a terminal profile of a mobile communication device, the network node comprising:
- means configured to wirelessly transmit a terminal profile modification instruction to the mobile communication device, wherein the terminal profile modification is operable to modify a terminal profile within a subscriber identify module of the mobile communication device based on the instruction to set a particular bit of the terminal profile for representing that a facility to forward location information is supported or not supported by the mobile communication device;
- means configured to wirelessly receive an acknowledgement of receipt of the terminal profile modification instruction from the mobile communication device,
- wherein the modified terminal profile is stored in the subscriber identity module of the mobile communication device and configured to be compared against a location query relative to the location of the mobile communication device before the location information of the mobile communication device is forwarded.
