A communication system for a vehicle includes an interior assembly and an in-vehicle communication control that is located in the vehicle remote from the interior assembly. In this disk cartridge, a chucking plate for chucking a disk on a turntable, driven by a spindle motor, is placed on the middle of the disk so the chucking plate is vertically movable together with the disk. If the mate service request arrives subsequent to the expiry of the waiting timer, the PCRN may then generate a subsequent PCC rule to replace the previously generated rule, with the new PCC rule incorporating information from both of the mate service requests.
