Controlling Radio Emission from a Mobile Terminal in a Critical Area

A method in a first radio network node for controlling radio emission from a mobile terminal, wherein the mobile terminal is located in a critical area in which radio emission from the mobile terminal is to be at least partly reduced, and wherein a radio communication system comprises the first radio network node and the mobile terminal, the method comprising:

• sending a location parameter of the critical area to the mobile terminal, wherein the critical area has a geographical location and the location parameter indicates the geographical location of the critical area, and
• sending a first set of control parameters to the mobile terminal, wherein the first set of control parameters comprises at least one radio access technology parameter indicating a radio access technology for which operation of the mobile terminal is restricted, wherein the location parameter and the first set of control parameters are useable by the mobile terminal for controlling radio emission therefrom.

A first radio network node configured to control radio emission from a mobile terminal, wherein the mobile terminal is located in a critical area in which radio emission from the mobile terminal is to be at least partly reduced, and wherein a radio communication system comprises the first radio network node and the mobile terminal, wherein the first radio network node comprises a sending unit configured to send a location parameter of the critical area to the mobile terminal, wherein the critical area has a geographical location and the location parameter indicates the geographical location of the critical area, and to send a first set of control parameters to the mobile terminal, wherein the first set of control parameters comprises at least one radio access technology parameter indicating a radio access technology for which operation of the mobile terminal is restricted, wherein the location parameter and the first set of control parameters are useable by the mobile terminal for controlling radio emission therefrom.

A mobile terminal configured to control radio emission from the mobile terminal, wherein a radio communication system comprises the mobile terminal and a first radio network node, the mobile terminal comprising:

• a receiving unit configured to receive a location parameter of a critical area from the first radio network node, wherein the critical area has a geographical location and the location parameter indicates the geographical location of the critical area, and to receive a first set of control parameters from the first radio network node, wherein the first set of control parameters comprises at least one radio access technology parameter indicating a radio access technology for which operation of the mobile terminal is restricted, and
• a processing unit configured to determine a geographical location of the mobile terminal and to control radio emission from the mobile terminal based on the first set of control parameters, the location parameter, and the geographical location of the mobile terminal.
