• Bar all outgoing calls
• Bar all outgoing international calls
• Bar all outgoing international calls except those directed to
the home PLMN.
** barring password required **
SUPPLEMENTARY SERVICES

international roaming)
• Barring of all incoming calls
• Barring of incoming calls when outside home PLMN
** barring password required **
SUPPLEMENTARY SERVICES
Call waiting

an audible tone, for incoming call.
The incoming call can be any type of basic service
including speech, data or fax.

or SMS.
** to activate call waiting dial *43#
SUPPLEMENTARY SERVICES
Call hold
This supplementary service enables the subscribers to put
the basic normal telephony service on hold in order to set
up a new call or accept a waiting call.
SUPPLEMENTARY SERVICES
Calling line identification services:
These cover both the presentation and restriction
of the calling line identity.
The presentation part of the service supplies the
called party with the ISDN or MSISDN number of
the calling party. The restriction service enables
calling parties to restrict the presentation of their
number on the MSs of called parties
SUPPLEMENTARY SERVICES
Closed User Group (CUG)
The CUG service enables subscriber connected to the
PLMN/ISDN and possibly other networks, to form groups
in which access is restricted.
Example: members of a specific CUG can communicate
with each other, but generally not with users outside the
group.
INNOVATIVE FEATURES
Regional and local subscription
These features allow subscribers to subscribe to a service
in a specified geographical area.
Requests for service outside the area are rejected with the
exception of emergency calls and SMS.
For local subscriptions, the geographical area consists of a
number of cells, and for regional subscription, the area
consists of LAs.

Short Message Services (SMS)
The service allows simple text message consisting of a
maximum of 160 alphanumeric characters to be sent to or
from an MS.
If the MS is switched off, or has left the coverage area, the
message is stores in a Short Message Service Center
(SMS-C).
When the mobile is switched on again or has re-entered the
network coverage area, the subscriber is informed that
there is a message.
Enhanced Messaging System (EMS)
•
EMS can support relatively simple pictures,sounds and
animation.
• EMS messages that are sent to devices that do not support
it will be displayed as SMS transmissions.
• It is a 3GPP standard.
MULTIMEDIA MESSAGE SERVICE
(MMS)
• MMS means a multimedia presentation which consists
of music, voice, image, text, video and graphics all
synchronized across a common timeline.
•
“Synchronized Power Point Presentations”.
MULTIMEDIA MESSAGE SERVICE
(MMS)
• MMS-enabled mobile phones enable subscribers to
compose and send messages with one or more multimedia
parts. Mobile phones with built-in or attached cameras, or
with built-in MP3 players are very likely to also have an
MMS messaging client -- a software program that
interacts with the mobile subscriber to compose, address,
send, receive, and view MMS messages.

Instant Messaging
It enables to communicate with another
individual in real time, analogous to a
telephone conversation but using text based
communication instead of voice-based
communication.
Streaming
• It enables real time or on demand
distribution of audio, video and multimedia
on the internet.
• It is simultaneous transfer of digital media
(video,voice and data) so that it is received as
a continuous real-time stream.

Location Based Applications
Location Based Applications
In this age of significant telecommunications competition, mobile
network operators continuously seek new and innovative ways to
create differentiation and increase profits. One of the best ways to do
accomplish this is through the delivery of highly personalized
services. One of the most powerful ways to personalize mobile
services is based on location.
Positioning
One of the most obvious technologies behind LBS is positioning, with
the most widely recognized system being the Global Positioning
System (GPS). There are however, other means of positioning in
addition to GPS. These other technologies are network based
positioning and typically rely on various means of triangulation of the
signal from cell sites serving a mobile phone. In addition, the serving
cell site can be used as a fix for location of the user.
Geographic Information Systems
Geographic data is an important aspect of any location system.
Geographic Information Systems (GIS) provide the tools to
provision and administer base map data such as man made
structures (streets, buildings) and terrain (mountains, rivers). GIS is
also used to manage point-of-interest data such as location of gas
stations, restaurants, nightclubs, etc. Finally, GIS information also
includes information about the radio frequency characteristics of the
mobile network. This allows the system to determine the serving
cell site of the user.

Traffic Information
APPLICATION OVERVIEW
This service both collects and distributes traffic information. Traffic information
is very important need for city dwellers. Systems can estimate traffic
information by sampling mobiles in automobiles on freeways anonymously to
determine average velocity of vehicles. If this is not possible in locataion more
static information can be collected from city authorities. All this information is
mapped and sent to mobile users who request it.
• Stickiness : Daily traffic info. pushed during
rush hours via SMS/MMS
• Most people need to know the current
traffic sitution on their route.

Push-To-Talk (PTT)
Push-To-Talk (PTT) is a two-way communication service that works
like a "walkie talkie".
A normal cell phone call is full-duplex, meaning both parties can
hear each other at the same time. PTT is half-duplex, meaning
communication can only travel in one direction at any given
moment.
To control which person can speak and be heard, PTT requires the
person speaking to press a button while talking and then release it
when they are done. The listener then presses their button to
respond. This way the system knows which direction the signal
should be traveling in.
Push-To-Talk over cellular (PoC)
The Motorola, Nokia, Ericsson, Siemens, Huawei, Mobile
Tornado, Wireless ZT, etc. versions of PTT are based on
2.5G or 3G packet-switched networks and use SIP and RTP
protocols. These particular versions of PTT are called
"Push to Talk over Cellular", which is abbreviated "PoC".
** Session Initiation Protocol (SIP)
Real-Time Transport Protocol (RTP)
