What is a Telephone Ringtone?

A sonnerie téléphone is an audio sound that can be stored in memory and played by the phone. These sounds can be monophonic, polyphonic or realtone.


A ringtone can be a single note or a group of notes with pauses and may contain a melody. It can also be a recorded sound file in a format like MP3 or WMA.


Usually, a ringtone is sent by a user in the form of a short message or in USSD (Unstructured Supplementary Service Data). The mobile station reads the message with the help of an identifier and stores the received ringtone in non-volatile memory 14 if the identifier is valid.


When the message is received, the DU processor 8th translates it into ASCII characters and further executes a transformation of the ASCII characters into a ringtone sequence. Then, the ringtone is stored in the non-volatile memory 14 and displayed to the user as a received ring tone, if the identifier is valid.


Some ringtones are stored in the mobile station's memory for a long time until they are used by the user, for example as a default ringtone or as a ringtone for a contact. Others are stored in the user's memory for a very short time, such as a notification ringtone or an alarm ringtone.


In addition to the ringtones, various other types of signals can be programmed by a user. These signals include power ringing, a distinctive signal that alerts the user of an incoming call, and audible ringing, which indicates when a contact is engaged or disconnected by the user.
