Glossary
EMS (Enhanced Message Service)
An adaptation of the Short Message Service (SMS)
that allows you to send and receive ring tones and
service provider's logo, as well as combinations of
simple media to and from EMS-compliant handsets.
Because EMS is based on SMS, it can use SMS
centres the same way that SMS does. EMS works
on all Global System for Mobile communications
(GSM) networks. EMS senders can use text,
melodies, pictures, sounds, and animations to
enhance the expressive power of messages that are
limited by the display constraints of mobile devices.
GPRS (General Packet Radio Service)
New non-voice value-added service that allows
information to be sent and received across a mobile
telephone network. GPRS provides continuous
connection to the Internet for mobile phone and
computer users. It is based on the Global System
for Mobile Communication (GSM) circuit-switched
cellular phone connections and the Short Message
Service (SMS).
GSM (Global System for Mobile
Communication)
International standard for cellular communication,
guaranteeing compatibility between the various
network operators. GSM covers most European
countries and many other parts of the world.
