It shows clearly that the central axis of future communication service market is changed rapidly into mobile communications from conventional telephone.
The other side, as the rapid development of mobile communications, the improvement of wave propagation environment and communication quality were appeared with an important problem. To solve the problem, a technical study and a development are being repeated. But, since a legal restrictions of the mobile phone are relatively many than the wire phone, it has a great difficulty that mobile communication provide its subscribers with a better quality service.
In this study, I examine to restriction connected with the cases of controls according to installation, operation of base station and propose a plan for relax restriction for mobile communication service.
