The test set provides two alternative methods for performing hard handoffs, implicit and explicit.
An explicit handoff allows several handoff parameters to be changed without a handoff attempt. Before performing an explicit handoff, you must first specify the handoff parameters from the Handoff Setup menu (see
Setting Hard Handoff Parameters
). A handoff attempt is performed only when the
Execute Handoff
key is pressed. See
How Do I Perform a Hard Handoff?
.
An implicit handoff is simply a side effect of changing a parameter and a handoff attempt is performed immediately. For example, when you enter a new channel number in the
Channel
field or select a new
Cell Band
, the setting is immediately applied and the MS is directed to the new band or channel.When in the IS-95 or IS-2000 system, changing the following parameters results in an implicit handoff:
Note that handoff to the following bands and channels is not supported: TACS (Band Class 2), 1800 MHz (Band Class 8), 900 MHz China Cellular (Band Class 9), 2.5 GHz IMT-2000 Ext* (Band Class 13), US 2.5 GHz (Band Class 16), US 2.5 GHz Forward Link (Band Class 17).
