Match the following with link quality measurement and handoff initiation :
| (a) Networked-Controlled Handoff (NCHO) | (i) MS connect to BS |
| (b) Mobile-Assisted Handoff (MAHO) | (ii) Process via channel the target BS |
| (c) Forward Handoff | (iii) First Generation Analog Cellular System |
| (d) Hard Handoff | (iv) Second Generation Digital Cellular System |
(a) (b) (c) (d)
UGC NET - 2012,
Answer: A
Network-controlled handoff, NCHO, is the handoff method of first generation analog cellular systems (iii), while mobile-assisted handoff, MAHO, is used in second generation digital cellular systems (iv). A forward handoff is made by processing through a channel of the target base station (ii), and a hard handoff is one in which the mobile station connects to the new base station after leaving the old one (i). So the code is (iii), (iv), (ii), (i), option (A).
