A mobile communication device is provided that enables appropriate use of a network connection between the mobile communication device and a telecommunications network by a tethered computing device. When the load level has entered the overload region, cycle-time prolongation processing is performed in order to obtain a cycle prolongation time corresponding to the load level and to prolong the molding cycle by the cycle prolongation time. For instance, the cache indicates that a GGSN only supports GTPV0. The cavity is of sufficient size to receive therein a syringe.
