A method for forming an electric device having power switches around a logic circuit including: forming a logic circuit on a substrate; forming a plurality of power switches around the logic circuit; and coupling first ends of the power switches to a voltage end, and coupling second ends of the power switches to a power receiver of the logic circuit. The crimp terminal includes: a first engagement portion formed at one end in a direction orthogonal to an insertion direction that the crimp terminal is inserted into the terminal accommodating chamber; and a second engagement portion which is provided at the other end which can be engaged with the first engagement portion. The MS, before handover, transmits a Subscriber Station Basic Capability Request, and receives a SS Basic Capability Response from the BST via the BSC.
