AGCH
: Also known as: Access Grant Channel Access
Grant Channel (AGCH) is a downlink channel (base to mobile) used by
a BS (Base Station) to tell the MS (Mobile Station) which DCCH
(Dedicated Control Channel) to use, after the MS has previously
requested access to the network by sending a message over the RACH
(Random Access Channel). The AGCH is used to assign resources to
the user who has requested access to the network, and the BS
allocates a TCH (Traffic Channel) or SDCCH (Stand-Alone Dedicated
Control Channel) to the MS, allowing it access to the
network |

Algebraic Code Excited Linear
Prediction
: Also known as: ACELP Algebraic Code Excited
Linear Prediction, or ACELP, is a speech compression system, used
to provide a good standard of speech quality when the network is
operating at low data rates (i.e. narrow bandwidth). The analogue
voice signal is converted to a digital data signal, so that it can
be compressed for transmission over the network, and the process is
then reversed at the other end when the digital data is converted
back to an analogue voice signal. The quality of the reproduced
speech will appear to be much better at the receiving phone than
would have been the case if an ACELP system had not been used. The
technology associated with ACELP is defined by the ITU-T
(International Telecommunications Union-Telecommunication
Standardization Sector) and this has been used for a long time as a
standard on the Internet for voice applications, being integrated
into software such as Microsofts MediaPlayer?. |

Alphanumeric
: Alphanumeric is a term referring to
information that contains a combination of alphabetic letters or
words ("alphas") and numbers ("numerics"). Punctuation and other
symbols are also usually interpreted to be included in the term
alphanumeric. Alphanumeric displays are those that can show at
least all of the letters of the alphabet and the numbers 0 to 9.
Alphanumeric Directory Alphanumeric Directory refers to the part of
a phone that stores the user's list of names and phone numbers, so
that they may be easily retrieved. Alphanumeric DisplayAlphanumeric
Display is the display output device on a phone, typically an LCD
screen, which has the ability to display both text and numbers.
Alphanumeric Memory DialAlphanumeric Memory Dial is a special type
of dial-from-memory option on mobile phone handsets, which enables
the name of an individual and their phone number to both be
displayed for dialling purposes. This feature is now an accepted
standard on modern mobile phones. Alternatively, the name can also
be recalled by typing the letters on the phone keypad. By contrast,
the standard memory dial feature will recall just the numbers from
a number-only location. Alphanumeric MessagingAlphanumeric
Messaging is the capability of a phone to send and receive messages
(e.g. SMS messages) that contain both text and numbers |

American Standard Code for Information
Interchange
: Also known as: ASCII The American Standard
Code for Information Interchange (ASCII) is a standard coding
system developed by the USA Standards Institute. ASCII is
universally used to represent letters, numbers, punctuation marks,
symbols and control codes, which makes it possible to pass data
between computers and within communication systems (e.g. to mobile
phones). Digital equipment can only understand numbers, and ASCII
code gives every symbol or character a unique number in order to
identify it. The coding system is efficient, with each character
being represented by a single byte. There is a basic character set
of 128 codes numbered 0 to 127 (which uses 7 bits per character),
or an extended character set of 256 codes numbered 0 to 255 (which
uses 8 bits per character). ASCII files appear as unformatted plain
text, i.e. without any tabs, bold, italics, or other codes that
word processors introduce when formatting text. ASCII files are the
standard text format for SMS messages |

AMPS
: Also known as: Advanced Mobile Phone Service
Advanced Mobile Phone Service (AMPS) is a first generation analogue
cellular telephone system that originated in the USA in the 1980s.
AMPS is still the most widely deployed cellular system in the
United States, and has been used in other countries of North and
South America, as well as the Asia/Pacific region, although it is
not compatible with European mobile phone standards. AMPS can be
found in countries such as Canada, Australia, Hong Kong, New
Zealand, South Korea, Singapore, Taiwan, Thailand and Israel. AMPS
operates in the 800 and 900 MHz frequency bands. Frequency Division
Multiple Access (FDMA) is used to divide each band of operating
frequencies into 30 kHz channels. Adjacent cells will then employ
different channels for their transmitted and received signals, so
that one cell does not interfere with another, and as a user moves
between cells the channels change without any noticeable
transition. AMPS was updated with digital cellular service, i.e.
digital AMPS (DAMPS), by adding Time Division Multiple Access
(TDMA) to each channel |

Animated Screensaver
: Animated screensaver is a changing pattern or
animation, which replaces the original screen image when a mobile
phone has been idle for a predetermined period of time. The use of
a screensaver is designed to prevent damage that might result when
fixed bright images remain on the screen for long periods. Only the
more recent mobile phone models currently include animated
screensavers |
|
Animation
: Animation is a moving image produced by
sequentially displayed image frames, which creates the illusion of
movement. Mobile phone animations usually consist of short,
animated greetings and messages in a variety of sizes, colours, and
levels of complexity |

Answering Machine
: Answering machine is a device that
automatically answers a telephone call when the recipient is for
some reason unable to answer it personally. Typically, a user
stores an outgoing message to tell callers that the phone cannot be
answered personally, and the caller is then requested to leave a
recorded message stating the purpose of their call, which the user
can playback at a convenient time. Conventional landline answering
machines often use magnetic tape or a microchip memory to record
messages. Some mobile handsets are capable of storing messages in
their internal memory, and most mobile operators provide an
answering service whereby subscribers can dial a special number and
listen to their stored messages |

Ariel
: Also known as: antenna The antenna (or aerial)
is the physical part of a mobile phone that is designed to receive
or transmit the radio frequency signals, which the�handset uses to
communicate with the telephone network. A mobile may contain an
internal antenna that is concealed within its case, or there may be
a short or stubby external antenna that protrudes about 3 cm or
more outside the case. Some mobile phones include an FM radio, and
in this case the headset lead usually acts as the radio's antenna.
The headset must then be connected to the phone to ensure good
reception |

Audible Keypad Tone
: Audible Keypad Tone is a facility that can be
set on some handsets, which causes them to play a tone when the
keys are pressed, so confirming that they have operated correctly.
This was introduced to reduce airtime charges to incorrect numbers,
although it also provides a better interface and positive feedback
for the user. The sound played is usually the DTMF tone relevant to
that particular number, and for consistency, another non-DTMF tone
can be played when control keys are pressed |
