CM Service Request Setup Parameters

• CM Service Request Ignore State

  If you set the CM Service Request Ignore State to on , the test set will act like the OTA message is never received. If it is set to be off , the test set will not ignore the message. Meanwhile, you can further set CM Service Request Reject State to on /off to reject/accept CM Service Request.

  When CM Service Request is ignored, when and who to release the call depends on the timer T303, see Configurable Timers . If T303 expires, the MS should start to release the call.

  The command to set the CM Service Request Ignore State is

  CALL:PPRocedure:CMService:IGNore[:STATe] .

• CM Service Request Reject State

  If you set the CM Service Request Reject State to on , the test set will reject the CM Service Request from the mobile station and send to it the CM Service Request Reject Cause . If it is set to be off , the test set will not reject the CM Service Request from the mobile station.

     

  NOTE

  When the specific OTA message is ignored, the corresponding OTA reject settings are not applied regardless the CM Service Request Reject State is set to ON or OFF.
