Q: As shown in the following figure, we use ‘Relative Signal Strength with Hysteresis
and Threshold’ handoff initiation approach, if the threshold is T3 and hysteresis
margin is h, which point would the handoff occur?




A: D


Q: What is the main difference between nonpriority handoff scheme and priority
handoff scheme?
A: In nonpriority handoff scheme, all channels are shared by both originating and
handoff request calls. However, in priority handoff scheme, priority is given to
handoff requests by assigning SR channels exclusively for handoff calls among the S
channels in a cell; the remaining SC (= S–SR) channels are shared by both originating
calls and handoff requests.

Q: Please give the system model and state transition diagram of the priority and
queuing handoff scheme?
A: System model:                                     State transition diagram:
