A UE determines that an SMS over IP is in an unavailable state through communication via a radio access network. A first quantity of adhesive is applied to the inner surface of the strip adjacent to the first end, a second quantity of adhesive is applied to the inner surface of the strip adjacent to the second end, and a third quantity of adhesive is applied to the inner surface of the strip in a region spaced from the first and second ends. The pre-pulse is formed to be reduced in an application rate to the RF excitation pulse as approaching to an outward position in the k-space. An insert part may be arranged between the two wall sheets with positive locking, and may fluidly connect the storage compartment and the access opening. The buyer also may be a licensee, who purchases the license contract to practice the intellectual property rights.
