OBJECTIVES
 To develop IMS application on Laptops, PDAs and Cell phones.
 To Develop and implement IMS network.
 To interwork WiMAX with IMS as core network for accessing the eContents.
 To install and test the performance of the WiMAX - IMS setup.
 To integrate Wireless mesh network with IMS and Wimax
in the
foliage environment
 To achieve seamless connectivity for the accessing the e-Content
material by establishing WiMAX.
OVERVIEW OF THE PROPOSAL

IMS(IP Multimedia Subsystem) is used to deliver the e-Contents to the user
equipment. It acts as the core network.

Wireless Mesh Network is used to deliver the e-Contents at last mile since
it will reach the mobile devices even in the dense foliage environment.

To deliver this e-Content to a extension center located far away from the
university, Wimax
is used. Wimax has high bandwidth and can be
transmitted over long distances.
PROPOSED ARCHITECTURE
FEATURES OF THE PROPOSED
ARCHITECTURE

Open source

User-centric services

Extensive to stay ahead

Linked with the operator environment
Soft switch

A softswitch is a central device in a telecommunications network
which connects calls from one phone line to another

Soft switches run on commercial computers and operating systems,
and they provide open applications programming interfaces.

Soft switch architecture separates service control from service
access and uses an IP-based core layer in the switching network
SOFT SWITCH vs IMS
Features of soft switch
Integration/Incorporation
 Convergence of voice and data
 Combination of telecom & internet technologies
 Reuse PSTN database & IN services in packet networks
 Multiple sources for app development & deployment
 Decreased operating costs
Standardization
 Standard interfaces (protocols) for communications
 Open standards (APIs) for service creation
 Customized services created by users themselves
 Better scalability
Migration from Soft switch to IMS
Step 1:
 The softswitch is decomposed into two
logical components
 subscriber facing unit to AGCF
 PSTN facing unit to MGCF
 By separating the softswitch into these
components, the network can be more
easily scaled for better overall network
efficiencies
Migration from Soft switch to IMS
Step 2:
 Addition of SIP based services by
deploying AS.
Step 3:
 SIP end points are added to provide the
users with high QOS.
 SIP end points are connected with PCSCF which is connected to policy server.
 Policy server provide the required Qos
and Security.
Migration from Soft switch to IMS
Step 4:
 Fixed/Mobile convergence
 FMC will address the business needs
relating to Triple play service.
 HSS is added to the network to maintain
the user database. It maintains the
subscribers data uniformly between
cellular and ip network.
IP MULTIMEDIA SUBSYSTEM(IMS)

IMS defines a complete architecture and framework that
enables the convergence of voice, video, data and mobile
network technology over an IP-based infrastructure

It fills the gap between the two most successful
communication paradigms, cellular and Internet technology

video, and voice
PROPOSED ARCHITECTUREFor University Extention Centre
WIRELESS MESH

WMN consists of access points and clients.

The clients connect through these access points either
directly or in multi hop fashion which enables the
network to have a wide coverage compared to the
traditional networks.

Provides an excellent solution for last mile connectivity
in difficult terrain like dense foliage

Highly reliable and robust in nature.
Wireless Mesh Network
Proposal




IMS can provide access to multimedia content.
Wireless Mesh can be used in a dense foliage environment so that a
user can access the e-Contents even if he is sitting under the tree or
in the foliage environmet or in any place in the university campus.
Wimax can be used to transmit it for longer distances. So it is
possible to access the e-Contents from the university extention
centres.
With the use of technologies ie., integrating IMS, WiMax and the
Wireless Mesh, the e-Contents can be delivered to the any user
equipment such as laptop, PDA and other devices.
Feasibility of IMS
The IMS technology has been implemented and tested
by many service enablers such as Ericsson, Nokia
Siemens, Alcatel Lucent, etc. Many testing procedures
are also introduced to check their working and they are
quite successful.
 Since IMS can be interfaced with any access network,
the issue of incompatibility would not arise.

Justification & importance of project




With WiMAX as the access network a wide coverage
area of about 50 kms is possible. Hence access to the econtent is made available to everyone.
Interworking WiMAX with IMS as the core network
provides the end user with access equipment
independent service
The mesh network provides an excellent solution for last
mile connectivity in difficult terrain like dense foliage.
Hence the user can access the e-content with different
equipments such as Laptop, Mobiles, PDAs, iPOD, etc.
Year wise contribution to the project


I year: Interface between server with desktops, laptops
in a seamless fashion using the IMS interface for
multimedia e-Content within in the University building
premises.
II year: To deliver the same content over laptops, tablet
pc's, PDA's and cell phones with suitable
communication software interface within the 800acres
campus situated in the midst off very robust foliage
environment for seamless operation and delivery of
multimedia content with appropriate content. Extention
of the e-Content delivery to a remote station(University
extention centre located 25 to 50 kms away from the
main campus) using WiMax.
Year wise contribution to the project-Contd.,

III year: Using the modellling and simulation attempted
in the second year for IMS content delivery on several
laptos, tablet pcs, PDA's etc., it is proposed to interface
IMS with WiMax at the remote station(University
extention centre) for last mile delivery.


IV year: As there is a distinct possibility of extention
centre being situated in a totally different environment
from the university premesis it is proposed to model the
surrounding terrain and the environment for accessing
the multimedia e-Content in a seamless fashion.
V year: To integrate the entire activity( I,II, III, IV) in a
holistic manner and complete the entire system model.
