A system for selectively disabling use of at least selected features of a stand-alone electronic device under a predetermined set of conditions. The system establishes a state of the set of conditions as being satisfied or unsatisfied, communicates the state to the electronic device, and disables the selected features if the state is satisfied. In one embodiment, the system may be advantageously be used to prevent vehicular accidents by at least partially disabling non-emergency use of a wireless telephone in a moving vehicle. In another embodiment, the system may be used to disable features of an electronic device within a predetermined area having a boundary that is independent of a communications network cell.

A system for selectively disabling use of at least selected features of a stand-alone electronic device under a predetermined set of conditions. The system establishes a state of the set of conditions as being satisfied or unsatisfied, communicates the state to the electronic device, and disables the selected features if the state is satisfied. In one embodiment, the system may be advantageously be used to prevent vehicular accidents by at least partially disabling non-emergency use of a wireless telephone in a moving vehicle. In another embodiment, the system may be used to disable features of an electronic device within a predetermined area having a boundary that is independent of a communications network cell. the connection from the second cell in the downlink direction; and broadcasting to radio user nodes in or near the first cell an avoid cell message in order to cause the radio user nodes to avoid using the first cell for downlink transmissions. 10. In a radio communications system for conducting communication between a radio network and radio user nodes over a radio interface, apparatus for use in the radio network, comprising: a detector for detecting a first load condition in a first cell area serviced by the radio network and a second load condition in a second cell nearby the first cell, and a controller configured to perform the following tasks: to avoid radio transmissions associated with a connection between a radio user node and the radio network from the first cell in a downlink direction to the radio user node, and to permit a radio transmission associated with the connection from the second cell in the downlink direction, and an uplink transmission from the radio user node in the first cell. 11. The apparatus in claim 10, wherein the first load condition is an overload condition and the second load condition is not an overload condition. 12. The apparatus in claim 10, wherein the uplink transmission indicates that downlink transmission should be from the second cell. 13. The apparatus in claim 10, wherein the prevented radio transmission is a traffic type of radio transmission, the controller is configured to perform the further task of: transmitting a control signal radio transmission associated with the connection from the first cell to the radio user node in the downlink direction. 14. The apparatus in claim 13, wherein the cell parameter is received signal strength or signal quality. 15. The apparatus in claim 10, wherein the controller is configured to perform the further task of: broadcasting to radio user nodes in or near the first cell a scaling factor for scaling a cell parameter value measured by the radio user nodes in the first cell. 16. The apparatus of claim 10, wherein the controller is configured to prevent radio traffic transmissions from the first cell to the radio user node. 17. The apparatus in claim 16, further comprising. a detector configured to detect a signal parameter of signals received from cells in an active set of cells including the first cell, wherein the controller is configured to select the cell in the active set that has the highest detected signal parameter value. 18. The apparatus in claim 17, wherein the signal parameter is received signal strength or signal quality. 19. The apparatus in claim 17, wherein the controller is configured to scale the signal parameter value corresponding to the first cell to reduce the signal parameter value corresponding to the first cell. 20. The apparatus in claim 19, wherein the controller is configured to scale the signal parameter value corresponding to the first cell in accordance with the level of congestion in the first cell. 21. The apparatus in claim 20, wherein the controller is configured to reduce the signal parameter value corresponding to the first cell as the congestion level in the first cell increases. 22. In a radio communications system for conducting communication between a radio network and radio user nodes over a radio interface, apparatus for use in the radio network, comprising: a detector for detecting a first load condition in a first cell area serviced by the radio network and a second load condition in a second cell nearby the first cell, and a controller configured to perform the following tasks with respect to a handover connection with a first leg between the first cell and the radio user node and a second leg between the second cell and the radio user node: to avoid radio transmissions associated with the handover connection between a radio user node and the radio network from the first cell in a downlink direction to the radio user node, and to permit a radio transmission associa ted with the handover connection from the second cell in the downlink direction over the second leg and a radio transmission over the first leg to the first cell in an uplink direction from the radio user node to the first cell. 23. In a radio communications system for conducting communication between a radio network and radio user nodes over a radio interface apparatus for use in the radio network, comprising: a detector for detecting a first load condition in a first cell area serviced by the radio network and a second load condition in a second cell nearby the first cell, and a controller configured to perform the following tasks: to avoid radio transmissions associated with a connection between a radio user node and the radio network from the first cell in a downlink direction to the radio user node; to permit a radio transmission associated with the connection from the second cell in the downlink direction; and to broadcast to radio user nodes in or near the first cell an avoid cell message in order to cause the radio user nodes to avoid using the first cell for downlink transmissions. 24. In a radio communications system for conducting communication between a radio network and radio user nodes over a radio interface, apparatus for use in a radio user node, comprising: a radio receiver configured to receive cell selection control information from the radio network identifying a first cell; and a controller configured to identify an active set of cells including the first cell and to select a cell from the active set other than the first cell to transmit traffic information to the user equipment in response to the cell selection control information, wherein the radio receiver is further configured to receive a transmitted cell selection indicator identifying the selected cell. 25. The apparatus in claim 24, further comprising: a radio transmitter configured to transmit traffic information from the user equipment to the first cell. 26. The apparatus in claim 24, further comprising: a radio transmitter configured to transmit control information to and from the user equipment to the first cell. 27. The apparatus in claim 24, further comprising: a detector configured to detect a signal parameter value of signals received from cells in the active set of cells, wherein the controller is configured to select the cell in the active set other than the first cell that has the highest detected signal parameter value. 28.
