Additional transitions and handoff
The transitions in the figure above are not complete. The "Off" state can be reached
from any state by turning off the forward 1xEV-DO signal (ON | OFF). Moreover, inci-
dents like an inactive session timeout or a loss of the radio link cause additional transi-
tions.
A 1xEV-DO dual-band handoff can be performed in the "Connected" state; see
2.2.8 Handoff
A handoff is the process of transferring an ongoing call or data connection from one
network to another. The R&S
CMW supports dual-band handoff between different
1xEV-DO band classes. A dual band handoff emulates only one 1xEV-DO cell with one
sector at a time.
The "Handoff" hotkey appears in the hotkey bar as soon as the R&S
CMW enters the
"Connected" state; see section
chapter 2.2.7, "Connection States"
Handoff includes:
1. Selection of the destination band class
2. Configuration of carriers and pilots in the destination sector.
3. Start of the handoff process.
After successful handoff, the connection is continued with the target sector replacing
the source sector.
The handoff steps for revision B are described below.
2.2.8.1
Preparing a Handoff
To prepare a handoff, an 1xEV-DO signaling application must be configured and an
1xEV-DO multicarrier connection must be set up.
For a multicarrier connection, set parameters in section "System" > "Carrier Configura-
tion".
