Terminology and
abbreviations
3GPP
3rd Generation Partnership Project.
AMR
Adaptive Multi Rate. For speech sounds and speech
coding.
API
Application Programming Interface.
ASP
Active Server Page. Server technology that generates
web pages dynamically.
Bearer
The method for accessing WAP from the phone, for
example GSM Data (CSD) and GPRS.
bFTP
binary File Transfer Protocol.
Bookmark
A URL and header/title stored in the phone.
Browsing session
The period from the first access of content until the
termination of the connection.
C/I
Carrier to interference ratio of radio signal.
Calling Line Identification (CLI)
Shows the number of the caller, or a picture assigned to
the number of the caller in the mobile phone display.
Not all numbers can be displayed. Network-dependent
service.
Card
A single WML unit of navigation and user interface.
May contain information to present to the user,
instructions for gathering user input, etc.
CDMA
Code division Multiple Access. A generic term that
describes a wireless air interface based on code
division multiple access technology.
CGI

DTMF or Touch Tone
Dual Tone Multi-Frequency signal – codes sent as tone
signals. Used for telephone banking, accessing an
answering machine, etc.
Dual band
GSM850/1900 or GSM 900/1800.
e-GSM
Extended GSM. New frequencies specified by the
European Radio Communications Committee (ERC)
for GSM use when additional spectrum is needed
(Network-dependent). It allows operators to transmit
and receive just outside GSM’s core 900 frequency
band. This extension gives increased network
capability.
EDGE
Enhanced Data rates for Global Evolution. EDGE uses
a new modulation schema to enable data throughput
speeds of up to 384kbit/s using existing GSM
infrastructure.
EFR
Enhanced Full Rate, speech coding.
EMS
Enhanced Messaging Service. Allows the user to add
simple pixel pictures and animations, sounds and
melodies to a text message. The EMS 3GPP standard
also includes text formatting.
EOTD
Enhanced Observed Time Difference. Positioning
solution currently used to satisfy FCC E911 mandate.
ETSI
European Telecommunications Standards Institute.
FR
Full Rate, speech coding.
