Browsing session

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
A collection of WML cards.
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
simple pixel pictures and animations, sounds and
melodies to a text message. The EMS 3GPP stand-
ard also includes text formatting.
ETSI
European Telecommunications Standards Institute.
FR
Full Rate, speech coding.
Gateway
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

GPRS
General Packet Radio Services.
