Method and system for restricting the operation of a radio device within a certain area
First Claim
1. A cellular radio system comprising:
- a multitude of base stations for offering a radio interface to mobile terminals for communicating general information to the mobile terminals and arranging for dedicated communication between a certain mobile terminal and the cellular radio system, and a certain first base station which has been previously appointed, prior to approach of a mobile terminal, as a beacon base station of an isolated, geographically defined restricted area, and which is located within or in the immediate vicinity of said restricted area, so that the cell of the beacon base station coincides with at least part of the restricted area, wherein said first base station is arranged to attract mobile terminals that are located within said restricted area to perform cell reselection into the cell of said first base station and to impose restrictions to the operation of mobile stations that have been attracted to the cell of said first base station.

Abstract
A cellular radio system comprises a multitude of base stations (101-106, 201-204, 211-212, 501-504) for offering a radio interface to mobile terminals (205, 215, 508). The radio interface is used for communicating general information to the mobile terminals and arranging for dedicated communication between a certain mobile terminal and the cellular radio system. For imposing restrictions to the operation of the mobile terminals on at least one isolated, geographically defined restricted area (107, 108, 200, 213) the system comprises a certain first base station arranged to transmit, similar to said general information, information about the nature of the restrictions applicable on said area to the mobile stations.

11. A cellular radio system comprising:
-
a multitude of base stations for offering a radio interface to mobile terminals for communicating general information to the mobile terminals and arranging for dedicated communication between a certain mobile terminal and the cellular radio system; and
a certain first base station which is a beacon base station located within or in the immediate vicinity of an isolated, geographically defined restricted area, so that the cell of the beacon base station coincides with at least part of the restricted area;
wherein said first base station is arranged to attract mobile terminals that are located within said restricted area to perform cell reselection into the cell of said first base station and to impose restrictions to the operation of mobile stations that have been attracted to the cell of said first base station; and
the beacon base station is a standalone station with no communication connection between said beacon base station and the rest of the cellular radio system. - View Dependent Claims (12)

13. A method for restricting the operation of a mobile terminal within a certain area, comprising the steps of:
-
providing a radio interface for the mobile terminal through a number of base stations;
using said radio interface for general broadcasts on a common downlink channel;
attracting mobile terminals that are located within a certain isolated, geographically defined restricted area to perform cell reselection into the cell of a certain first base station which has been previously appointed, prior to approach of a mobile terminal, as a beacon base station of an isolated, geographically defined restricted area and which is located within or in the immediate vicinity of the restricted area, so that a cell of the beacon base station coincides with at least part of the restricted area; and
imposing, through the operation of said first base station, restrictions to the operation of mobile stations that have been attracted to the cell of said first base station. - View Dependent Claims (14, 15, 16, 17, 18)
