Mobile Terminated SMS Delivery Status

Mobile Terminated SMS Delivery Status

Last updated: December 3, 2008

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

The test set provides the delivery status of mobile terminated SMS messages on the front panel, or it is accessible via the GPIB or HTTP interfaces.

MT SMS Message States

There are six possible MT SMS message states.

Using the GPIB Interface

The CALL:SMService:PTPoint[:MTERminated]:SEND:STATe? query returns a string indicating the state of the last message sent from the test set to the mobile station.

If the delivery status returned is "REJ", you can use the CALL:SMService:PTPoint[:MTERminated]:RCAuse? query to retrieve the reject cause value returned by the mobile station. See Reject Cause for the meanings of the possible cause values.

Using the HTTP Interface

The state of the last MT SMS message sent from the test set to the mobile station can be queried from the test set using an HTTP GET request with the following URL:

/sms/mtstate

The delivery state is returned in the body of the HTTP response.

Example using an internet browser

You can query the MT SMS delivery state through the HTTP interface using an internet browser by entering the following URL:

http://<x.x.x.x>/sms/mtstate

where <x.x.x.x> is the IP address of the test set sending the SMS to the mobile station. This example is illustrated in the following figure.

If the state returned is "REJ", the body of the HTTP response also contains the reject cause value as an integer. The reject cause value is placed in the response body after the REJ characters and separated from them by a single space character. For example, "REJ 211" is returned in the HTTP response if the MT SMS was rejected with a cause value of 211. See the following figure.

See Reject Cause for the meanings of the possible cause values.
