Operational Overview
The Test Set is able to simulate a cellular base station by using its hardware and
firmware resources to initiate and maintain a link with only one mobile station.
Unlike a real base station, which has many transceivers and can support many
mobile stations simultaneously, the Test Set has only one transceiver (it’s signal
generator and RF/AF analyzer) and can support only one mobile station at a time.
This means that the Test Set’s transceiver can be configured as either a control
channel or a voice channel, but not both simultaneously.
To establish a link with a mobile station the Test Set’s transceiver is configured as
a control channel. Once a link has been established and the user wishes to test the
mobile station on a voice channel, the Test Set sends the appropriate information
to the mobile station on the control channel and then automatically re-configures
it’s transceiver to the voice channel assigned to the mobile station. Once the voice
channel link is terminated the Test Set automatically re-configures it’s transceiver
back to being a control channel.
Analog to analog handoffs are accomplished in a similar manner. When a handoff
is initiated while on a voice channel, the Test Set sends the necessary information
to the mobile station on the current voice channel. At the proper time the Test Set
then automatically re-configures it’s transceiver to the new voice channel.
Figure 1, "Call Processing State Diagram," on page 266
illustrates the primary call
processing functions available in the Analog Call Processing Subsystem. Each
box represents a call processing state and includes the measurement information
available while in that state. The events which trigger transitions between the
various states are shown on the diagram. Events which are initiated from the Test
Set are shown in solid lines and events which are initiated from the mobile station
are shown in dashed lines. The annunciators on the call processing screens will be
lit while in that call processing state.
