The invention relates to a radio communication system, a base station control equipment and a mobile station equipment which constitute the radio communication system. The carrier includes a pad body, having a front side and a rear side, for detachably attaching on a user’s body and a pouch panel overlappedly provided on the front side of the pad body to define a storage compartment, for receiving a pistol-like weapon therein, between the pad body and the pouch panel. According to this method, a communication terminal accommodation apparatus carries out a radio communication with communication terminal apparatuses through an antenna 101, radio section 102, control section 106, logical link control section 104 and medium access control section 103a. Also, flip chip interconnections and flip chip packages made according to the methods of invention. The wear resistance varies at least substantially continuously within the abrasive-impregnated cutting structure.
