 WAP (Wireless Application Protocol) brings standard way to
connect mobile customers to content services
 Now nearly there are 2 billion mobile phone users!
50 Milj.

Today there are more than 150 million GSM
subscribers world wide
WAP

5.  The four modes for WAP communications are:
Mode UDP Port WTLS Security
◦ Connectionless 9200 No
◦ Connection 9201 No
◦ Connectionless 9202 Yes
◦ Connection 9203 Yes

8. ◦ Provide a two way communication between
the client (mobile phones in the fields) and
the server.
◦ This includes sending messages, receiving
messages and providing communication
history where the sent and received messages
can be viewed.
◦ Keep track of the contact details of the users
who communicate with the system.

9.  Basic functionalities of the system:
◦ The type of message can be assistance
request, so it identifies the type of message
accepted and store appropriately.
◦ A number of messages are expected to be
received at a time, Therefore the system
should be able to manage this.
◦ Different users with different access levels
will use the web application, therefore
manage the users of the system and provide
security.

10. Client Side System
 Selection of the Development Environment
 The client device (the mobile phone device) selected:
◦ Android OS based phone

11.  Forms Manager
◦ Viewing the Received Forms
◦ Editing the Received Forms
 Report Generator
◦ Viewing the Reports
◦ Analysis the Reports

12.  User Manager
◦ Logging in to the System
◦ Using the User Manager
 Creating New User/Contact
 Editing User/Contact
 Message Manager
◦ Sending SMS messages
◦ View Sent Messages
◦ Receiving SMS Messages

13.  Free and Open Source OS
 Future trend of development and application
 Localization capability
 Availability of applications
 Others: Handset layouts, Storage, Connectivity,
Messaging, Web browser, Java support, Media
support, Development environment, Market, support
of manufacturers, etc.

14.  De-facto world standard for wireless information
and telephony services on digital mobile phones
and other wireless terminals
"Internet in Every Pocket“
 Objectives:
 General environment for wireless applications
 Internet or Intranet-like services and content to
mobile terminals
 Network, bearer and manufacturer independent
 WAP Forum
 Started 1997 by Nokia, Ericsson, Motorola and
Unwired Planet
 Now close to 500 member companies

15.  The processor handling operational issues
may handle records that drill down deep
into the network operation details. These
records can cover such items as:
 A subscriber’s phone call attempt
 Whether the attempt was successful
 Whether the call was ended normally or was
dropped
 Date and time of the call

16.  Signal strength of the subscriber’s mobile
device as seen by the BTS
 In what cell site sector was the call set up
 Handover information
 What channel was used
 What frequency/time slot/PN number was
used

17.  GSM uses the Subscriber Information
Module (SIM card) which comes in two
forms – credit card sized format and thumb
tip size
◦ Embedded in the card is a microprocesor,
ROM and RAM

18.  Also contains data such as:
◦ The subscriber’s phone number which is referred to
as the MSISDN (Mobile Subscriber ISDN Number)
◦ The IMSI (International Mobile Subscriber Identity).
The IMSI is globally unique to a particular
subscriber
◦ The subscriber’s PIN which is used to prevent
unauthorized use of the mobile device
◦ Authentication Keys

19.  GSM developed in Europe in 1980s and
became an international standard 13 years
later
 Uses TDMA framework but not compatible
 Over 250 GSM Networks are presently
operating in 110 countries
 Data rates: 9.6Kbps to 14.4Kbps
 Carriers: Pacific Bell (now Cingular), Voice
Stream, and now AT&T Wireless

20.  Why is understanding Mobile networking
important?
◦ As voice and data merge over mobile
networks, you may be tasked securing both
◦ Wireless data handsets are inescapable
 Carrier infrastructures are very complex – to
what degree should one become acquainted?
◦ As security experts, there’s significant value
in obtaining this knowledge to prepare you for
the future
 Carriers have enjoyed closed networks, opening
them up to the Internet is a major challenge
