Answer»

Right answer is (c) Mobile MOVES from one cellular system to ANOTHER cellular system

Easiest explanation: An intersystem HANDOFF is initiated when a mobile moves from one cellular system to another during a course of a call. An MSC engages in an intersystem interference when a mobile becomes weak in a given cell and MSC cannot find another cell to which call can be transferred.
