3. If network revision A shall be used, select the preferred packet application, see
"Packet Configuration > Preferred Application"
Note, that the network release 0 uses always DPA and the network revision B uses
always MMPA.
4. If an EMPA/MMPA session shall be established, configure the network security
chapter 2.3.9.5, "Security Settings"
5. Configure any other settings as desired (as for a connection without the DAU) and
switch on the cell signal.
6. Register / attach the AT, see
chapter 2.2.2, "Initiating Signaling Tests"
7. Initiate a mobile originated packet data connection at the AT.
It is not possible to initiate a mobile terminated packet data connection at the
instrument.
There is no support for PPP authentication (for DPA) in the current release of
R&S
CMW.
2.2.4 Hybrid Mode
In hybrid mode (option R&S CMW-KS888), the AT registers in CDMA2000
®
1xRTT
and opens a session in CDMA2000
®
1xEV-DO at the same time to support voice and
data services. As the AT monitors the control channels of each network, it is now pos-
sible to connect calls in either standard without reregistering or renegotiating a session.
While the mobile has an open traffic channel allocated for a CDMA2000
®
1xEV-DO
data call, the mobile continues to perform idle state procedures on the CDMA2000
®
1xRTT system. When it is time to decode the CDMA2000
®
1xRTT paging channel slot,
the mobile will tune to the CDMA2000
®
1xRTT frequency. If a paging request comes in
and the mobile's Data Dedicated Transmission Mode (DDTM) setting is OFF, the
mobile will transition the CDMA2000
®
1xEV-DO data call from a PPP connected state
to a PPP dormant state and process the incoming page request.
In addition, the mobile may have the ability to originate a CDMA2000
®
1xRTT voice
call during a CDMA2000
®
1xEV-DO data call, again putting the data call to dormant
state.
2.2.4.1
Hardware Requirements
The CDMA2000
®
1xRTT and CDMA2000
®
1xEV-DO signaling applications both use
the SUU (Signaling Unit Universal) as the same hardware platform and can, in the
case of the hybrid mode, even run simultaneously on one SUU.
The R&S
CMW offers two ways to achieve the hybrid mode:
●
using a single SUU (scenario hybrid mode)
●
using two (or more) SUUs
