General Procedures for Soft/Softer Handoff Tests

Last updated: October 28, 2004

This section is only applicable to the lab application.

A. Establish a call.

  1. Connect the mobile station to the Test Set.
  2. Make a call (see How Do I Set Up a Call? ).

B. Set Up Soft/Softer Handoff Parameters

  1. Press the CALL SETUP key.
  2. Press the More key on the left side of the display until 2 of 3 is displayed.
  3. Press the Soft Handoff Info ( F1 ) key to display the Generated Pilot Level Information and Mobile Station Reported Pilot Level Information tables. See Generated Pilot Level Information and Mobile Station Reported Pilot Level Information .
  4. Press the Soft Handoff Parameters (F2 ) key (see Soft/Softer Handoff Parameters ), set the parameters as needed. For example, Handoff Type (Soft or Softer), Cell 1 and Cell 2 Pilot Level, etc. To display more Soft Handoff Parameters (such as Cell 2 Delay, etc.), turn the knob

       
    NOTE
    The F-Pilot Level field is corresponding to the Pilot Ec/Ior parameter in the TIA/EIA-98E standard and the F-FCH/Traffic Level field corresponding to the Traffic Ec/Ior parameter.

    Cell 2 Delay is relative to cell 1. It is set in units of microseconds (us), with a maximum of 13.02 microseconds (16 PN chips). It defaults to 12.21 us (15 chips).

       

  5. Press the Close Menu (F6 ) key.

C. Set the Cell 2 Power and AWGN Power

   
NOTE
The Cell Power field is corresponding to the Î or parameter in the TIA/EIA-98E standard and the AWGN Power field corresponding to the I oc parameter.
   

  1. Press the Cell 2 Power ( F1 ) key and enter a desired value (for example, -55 dBm/1.23 MHz). The Cell 2 pilot information is displayed in the Generated Pilot Level Information table (see Generated Pilot Level Information ).
  2. Press the AWGN Power ( F3 ) key and enter a desired value (in this example, set to Off).

D. Initiate the Soft or Softer Handoff

  1. Press the Soft Handoff (F4 ) key and select On from the table.

    The Mobile Station Reported Pilot Level Information table (see Mobile Station Reported Pilot Level Information ) should now show Cell 2, identified by a pilot PN offset of 36 in this example, as an Active pilot.

E. Clear Mobile Pilot Report

  1. Press the Soft Handoff Parameters (F2 ) key.

  2. Scroll down the list of parameters. Highlight and select Clear Mobile Pilot Report .

  3. Highlight Yes in the Clear Now? menu and press the knob.
  4. Press the Close Menu (F6 ) key.

F. Send Pilot Meas Request

  1. Press the Send Pilot Meas Request (F5 ) key.

   
NOTE
A call must be connected (Active Cell, Connected state) before the test set will display the Send Pilot Meas Request softkey.
