Bearer
The method for accessing WAP from the phone, for 
example GSM Data (CSD) and SMS.
Bookmark
A URL and header/title stored in the phone.
Browsing session
From the first access of content until the termina-

Calling Line Identification (CLI)
Shows the number of the person calling you in your 
mobile phone display. You can then make an 
informed choice as to whether or not to take the 
call. Bear in mind that not all numbers can be dis-

Card
A single WML unit of navigation and user interface. 
May contain information to present to the user, 
instructions for gathering user input, etc.
CB
Cell Broadcast. Cell Broadcast is a mobile technol-
ogy that allows messages to be broadcast to all 
mobile handsets and similar devices within a desig-
nated geographical area. The broadcast range can 
vary, from a single cell to the entire network. This 
technology is used to deploy location-based sub-
scriber services, such as regional auctions, local 
weather, traffic conditions and “nearest” services 
(like requesting the nearest service station or res-
taurant).
CBMI
Cell Broadcast Message Identifier
CGI
Common Gateway Interface.
CS
Circuit Switched.
CSD
Circuit Switched Data.
Deck

DRM
Digital Rights Management; controlling copying 
and distribution of contents, with respect to intel-
lectual property rights.
DTMF
Dual Tone Multi-Frequency signal – codes sent as 
tone signals. Used for telephone banking, access-
ing an answering machine, etc.
EFR
Enhanced Full Rate, speech coding.
EMS
Enhanced Message Service. Allows the user to add

A WAP Gateway typically includes the following 
functions:
A Protocol Gateway – the protocol gateway 
translates requests from the WAP protocol 
stack to the WWW protocol stack (HTTP and 
TCP/IP).
Content Encoders and Decoders – the content 
encoders translate Web content into compact 
encoded formats to reduce the size and number 
of packets travelling over the wireless data net-
work.
GIF
Graphics Interchange Format.
GPRS
General Packet Radio Services.
