Example text

The soft handoff can also be divided into two different types—multiway soft handoffs and softer handoffs. In this chapter, we focus primarily on the hard handoff. 1 2 HANDOFF IN WIRELESS MOBILE NETWORKS BS 1 MS BS 2 a. Before handoff BS 1 MS BS 2 b. 1 Hard handoff between the MS and BSs. A hard handoff is essentially a “break before make” connection. Under the control of the MSC, the BS hands off the MS’s call to another cell and then drops the call. In a hard handoff, the link to the prior BS is terminated before or as the user is transferred to the new cell’s BS; the MS is linked to no more than one BS at any given time.

This method is observed to provoke too many unnecessary handoffs, even when the signal of the current BS is still at an acceptable level. 2 Relative Signal Strength with Threshold This method allows a MS to hand off only if the current signal is sufficiently weak (less than threshold) and the other is the stronger of the two. 2 Signal strength and hysteresis between two adjacent BSs for potential handoff. on its relative value as compared to the signal strengths of the two BSs at the point at which they are equal.
