Operating Considerations for Status Field
When a call is made, the mobile station’s Active list is initialized to contain only
Sector A. When Sector B’s signal strength exceeds the threshold determined by
the entry in the
T_Add field, the mobile station will send a Pilot Strength
Measurement Message to the Test Set. The Test Set will then display “Candidate”
under the Status column for Sector B (Sector A and Sector B are identified by
their PN Offsets).
If the power level of Sector B exceeds Sector A power by more than
T_Comp*0.5 dB, the mobile station will send another Pilot Strength
Measurement Message, and the Sector B status will change to “To Add”, meaning
that Sector B has sufficient signal strength to be added to the mobile station’s
Active List.
When a softer handoff has begun, the Test Set will send a Handoff Direction
Message to the mobile station, adding Sector B to the mobile station’s active set.
The mobile station will then perform diversity combining of Sector A and Sector
B. When the next Pilot Strength Measurement Message is sent from the mobile
station, Sector A and Sector B Status will either be “Active” or “To Drop”. If an
“Active” pilot’s signal strength is decreased to a level determined by the other
Sector power and the entry in the T_Drop field, the status column will change to
indicate “To Drop” status. Conversely, if a “To Drop” pilot’signal strength is
increased to a level determined by the other Sector power and the entry in the
T_Comp field, the status column will change to indicate “Active” status
