Mobile communication system
First Claim
1. A mobile communication system including a first and second systems, each of said first and second systems having a land station and at least one mobile terminal capable of communicating with the land station,the land station of said first system having a broadcasting channel transmission means for transmitting status information via a broadcasting channel, and the mobile terminal of said second system having a broadcasting channel receiving means for receiving information in said broadcasting channel to obtain a broadcasting channel receiving condition and said status information, a giving interference estimation means for estimating giving interference level onto communication of said first system by said second system based upon said obtained broadcasting channel receiving condition and said obtained status information, and an output signal level control means for controlling output signal level of said mobile terminal of said second system based upon the estimated giving interference level.

Abstract
A mobile communication system includes a first and second systems. Each of the first and second systems has a land station and at least one mobile terminal capable of communicating with the land station. The land station of the first system has a broadcasting channel transmission unit for transmitting status information via a broadcasting channel, and the mobile terminal of the second system has a broadcasting channel receiving unit for receiving information in the broadcasting channel to obtain a broadcasting channel receiving condition and the status information, a giving interference estimation unit for estimating giving interference level onto communication of the first system by the second system based upon the obtained broadcasting channel receiving condition and the obtained status information, and an output signal level control unit for controlling output signal level of the mobile terminal of the second system based upon the estimated giving interference level.
