Mobile Messaging

• SMS
• EMS
• MMS
• Instant Messaging
• Streaming

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.
29
Enhanced Messaging System (EMS)

  graphics all synchronized across a common
  timeline.
• Synchronized Power Point Presentations.

31
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.

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.
36
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.
44
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.
45
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.
• Hosting Operator / ISP

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.
62
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)
