Setting Mobile-Originated SMS Parameters

Setting Mobile-Originated SMS Parameters

Last updated: February 28, 2011

This section is applicable to the lab application and to a test application with the required feature license.

You can control how the test set responds to a received SMS message and how the received message is displayed. These parameters are accessed from the Mobile-Originated SMS Parameter menu by pressing the F5 ( Short Message Service ) on Call Control 3 of 3 menu, then pressing the F3 ( Mobile-Orig SMS Parameters ).

For detailed front panel operation, see Set up the Mobile-Originated SMS parameters .

SMS Support Control

SMS Support: Used to specify how the test set responds to a received SMS message. See CALL:SMService:MORiginated:PROTocol . It is provided to support some of the CDG Stage 2 8.2 Mobile Station Originated SMS Tests (see Supporting CDG Stage 2 SMS Tests ),.

   
NOTE
When the SMS Support is set to any value other than Enabled, the test set will still process the received SMS message (same as Enabled), but post an error message associated with the setting of SMS Support (see SMS Support Settings ) when an SMS message is received. The test set will inform the mobile station regarding an unknown destination address, or that short message origination has been denied, or that SMS is not supported by the base station.
   

SMS Support Settings

SMS Support Setting

Error Message

Enabled

no error message.

Disabled

SMS MS Originated message received. Origination denied due to current SMS receive Protocol (Disabled).

Not supported

SMS MS Originated message received. SMS not supported by Base Station due to current SMS Receive Protocol (Not-supported).

Unknown Destination Address

SMS MS Originated message received. SMS not supported by Base Station due to current SMS Receive Protocol (Unknown Destination Address).

Network Failure

SMS MS Originated message received. SMS not supported by Base Station due to a network failure.

SMS Support Error Class

This setting determines what error class reported to the MS when a recieved SMS message (MO) is rejected due to the current value for SMS Receive Protocol is not Enabled. See CALL:SMService:MORiginated:ECLass .

Display Control

Row Index : Used to control the scrolling of the received message displayed in the Mobile-Originated Message window.

Display Format (Message/Addresses) : Specify whether ASCII or Hex format is used for displaying the received message contents in the Mobile-Originated Message window, as well as the call-back number (Call-Back Num) and the destination address (Dest Addr) in the Mobile-Originated SMS Info window.

  • If Auto is selected, the test set depends upon the message encoding of the received SMS message to determine the display mode of the Mobile-Originated Message window. If 7-bit ASCII, IA5, or GSM 7-bit default alphabet is shown in the Msg Encoding (see Mobile-Originated SMS Info ), ASCII mode is used. Otherwise, the Hex mode is used.
  • If Auto is selected, the display format for the Call-Back Num and the Dest Addr (see Mobile-Originated SMS Info ) is always ASCII.

SMS Call Drop Timer Control

The SMS Call Drop Timer setting (see CALL:SMService:MORiginated:DROP:TIMer[:STATe] ) determines whether the test set will start the SMS call drop timer

  • If it is set to On, the test set will start the timer. The test set will disconnect the call in service option SO6 or SO14 when an SMS message is not received within a fixed amount of time (about 5 seconds) since the call was established or when an Release Order from the MS is not received within a fixed amount of time (about 5 seconds) since the SMS message was received. See Test Set Behavior In Method 2 .

    It's desirable to turn on the SMS Call Drop Timer if you expect the test set to post an error and end the connection to clear any hanging query (SMS Status, etc.) when the mobile station should have sent an SMS message or disconnected the call but failed due to defect in mobile or issue in the link
  • If it is set to Off, the test set does not set a timer. The test set will maintain the connection waiting for an SMS message to be received or the call to be disconnected.

    It's useful to turn off the SMS Call Drop Timer when you are debugging or manually programming on the mobile station and do not want the test set to prematurely end the connection

   
NOTE
The SMS Call Drop Timer is different from the call drop timer which is accessed from the Call Drop Timer ( F10 ) on Call Parms 2 of 3 menu. The call drop timer indicates loss of reverse link. This timer also determines when the demodulation of the reverse link has been unsuccessful for a fixed period. See CALL:CONNected:DROP:TIMer[:STATe]<[:SELected]|:TA2000> .
