Mobile message type specification - Ringtone SMS

Introduction

Ringtones are little melodies and tunes created to give a unique sound to the GSM phone when the phone is ringing. Ringtones can be composed with an appropriate editor and they can be sent as SMS messages.

When a ringtone is sent as an SMS message, it is represented as a bitstream. This bitstream can be pictured as a set of hexadecimal numbers.

For example:

024A3A51D195CDD004001B20550590610560558550548540820849900000

The bit string contains the following sections:

00000010 <command-length> Number of command parts present
01001010 <ringing-tone-programming> Command part 1 (with filler bit)
0011101 <sound> Command part 2

Sending a ringtone in SMS

To send a ringtone message with Ozeki NG - SMS Gateway, you need to specify a message type which tells the software that the message body contains a ringtone. To send the above example, you would use the following message type: SMS:RINGTONE. In this case, the message type is made up of two sections. The first section tells the message server that this is an SMS message. This way only the service providers supporting this type of SMS will be considered to deliver the message. The second section is used by the service provider to use the ringtone encoder. This encoder will create the protocol data unit (PDU) that will be sent as an SMS message.

Example:

If you use the Database user to send and receive SMS messages with Ozeki NG - SMS Gateway, you can use the following SQL statement to send a ringtone message:
insert into ozekimessageout (receiver,msgtype,msg,status) values ('+36205222245', 'SMS:RINGTONE',
'024A3A51D195CDD004001B20550590610560558550548540820849900000','send');
