EMS gives the user the ability to send and receive 
melodies. These can be pre-defined sounds, 
downloaded from the Internet, received in SMS 
messages or composed by the user on the phone 
keypad or a PC.

Several sounds and melodies can be inserted in 
one message, and they can be combined with pic-
tures.

Phones supporting EMS include a set of pre-
defined animations. New pictures and animations 
can be downloaded from the Internet or received in 
SMS messages.

Pictures can be created and edited in the phone 
using a built-in Picture Editor. Several pictures can 
be inserted in one message, and they can be com-
bined with sounds and melodies. 

A part of the EMS standard is the support for con-
catenated messages, which means that the phone 
is able to automatically combine several messages 
both when creating and receiving EMS. This is use-
ful to be able to build and display messages with 
rich content since the amount of information in 
each SMS is limited by the SMS standards.

Users will find EMS as easy to use as SMS. At the 
moment 15 billion SMS messages, are sent every 
month worldwide. Roughly 80% of this traffic is 
user-to-user i.e. mobile phone users sending short 
messages to each other using the keypad of the 
phone to enter text. The remaining 20% is shared 
by downloads and notifications of different kinds.

Network operators can now enhance their services 
and attract more customers by offering pictures, 
animations, ring signals and melodies for download 
at their portals. Operators can charge more per 
EMS message since it contains more data. Thereby 
EMS adds more value to the operators and to the 
end users.

The Enhanced Messaging Service (EMS) was first 
submitted to the standards committees by Erics-
son. Ericsson presented the outline structure of 
EMS to the relevant ETSI/ 3GPP committees. The 
major mobile phone manufacturers and most oper-
ators are actively contributing to the 3GPP stand-
ards. Hence the EMS standard has evolved and is 

now stable and complete as part of the 3rd Gener-
ation Partnership Project (3GPP) technical specifi-
cation.

An EMS message can be sent to a mobile phone 
that does not support EMS, or only supports part 
of EMS. All the EMS elements i.e. text formatting, 
pictures, animations and sounds are located in the 
message header. The EMS contents will be ignored 
by a receiving phone that does not support the 
standard. Only the text message will be displayed 
to the receiver. This is true consumer-friendly 
standardization. 

A wide range of contents, applications and serv-
ices may be developed. Below is a list of examples 
and areas where messaging can be enhanced with 
EMS.

Messages usually originating from the keypad of a 
mobile phone can include pictures, animations, 
melodies, formatted text with EMS.

Notifying mobile phone users that they have new 
voice or fax mail messages waiting - including 
icons or melodies with EMS.
