My enquiry is from Handoff Strategies in portion The Cellular Concept – System Design Fundamentals of Wireless/Mobile

Answer 1

Right choice is (a) Queuing

To elaborate: Queuing of handoff requests is a method to decrease the probability of forced termination of a call due to lack of available channels. Queuing of handoff is possible due to the fact that there is a finite time interval between the time the received signal level drops below the handoff threshold and the time the call is terminated.
