  • Page 32: Step 4: Establish An Active Link With Mobile Station

    Step 4: Establish an Active Link with Mobile Station Step 4: Establish an Active Link with Mobile Station Background Call Connect/Disconnect Synchronization When the control program requires that an active link be established/terminated between the mobile station and the test set, the commands necessary to initiate the call connect/disconnect process are sent to the test set (for a BS originated/terminated call) or to the mobile station (for a MS originated/terminated call).
  • Page 33 Step 4: Establish an Active Link with Mobile Station Determining if a Call Connect/Disconnect Process is Completed The most common technique used by control programs to determine if a call connect/disconnect process has completed (either successfully or unsuccessfully), is to repeatedly query the call state using the CALL:STATus:STATe? query command inside a program loop.
  • Page 34 Step 4: Establish an Active Link with Mobile Station Example 1. Command Syntax: CALL:CONNected[:STATe]? Using the Call Connected State Query for Call Connect Synchronization The call-connected-state query only hangs if the call is in a transitory state, otherwise it immediately returns a 1 (Connected state) or a 0 (Idle state). At the start of a call connect process the call state is Idle.
  • Page 35 Step 4: Establish an Active Link with Mobile Station Using the Call Connected Arm Command for Call Connect Synchronization The call-state-change-detector arm command is used by the control program to tell the test set that it is expecting a change to the state of a call prior to initiating the state change.

This low amplitude will cause the level of the DSP sampler to be below a threshold required by the measurement algorithm to produce results of specified accuracy.
