Boundary definition system for a robotic vehicle

A method for granting access to restricted areas such as computers, doors, vehicles, or other areas to which access by a user is controlled. An access code is transmitted from a central computer via radio waves to a user's radio terminal, such as a mobile telephone. The radio terminal transmits the access code over a short-range radio link to a communication device at the restricted area. The communication device transmits the access code to the central computer, which compares the received code with the code that the computer transmitted to the radio terminal to determine whether access should be granted.

Method of authorization

The present invention relates to method and means for a system initiated subscriber information redistribution in order to achieve a load redistribution within a pool of core network nodes. The subscribers, that are affected by the redistribution, are determined by the bit values in their TMSI's. These specific TMSI's are then arranged to be treated as invalid by the cellular system. Messages etc. from subscribers with invalid TMSI's will be 'trapped' in the cellular system and the subscriber information that belongs to these subscribers will be redistributed to new core network nodes.
