    3. 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 e-Contents. • 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.

    4. 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.

    5. PROPOSED ARCHITECTURE

    6. FEATURES OF THE PROPOSED ARCHITECTURE • Open source • User-centric services • Extensive to stay ahead • Linked with the operator environment

    7. 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

    8. SOFT SWITCH vs IMS

    9. 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

    10. 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

    11. 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 P-CSCF which is connected to policy server. • Policy server provide the required Qos and Security.

    12. 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.

    13. 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

    16. WiMAX • Worldwide Interoperability for Microwave Access • Killer’ technology in every sense of the word! • Non-line-of-sight standard and can cover tens of miles Advantages of QoS in WiMax • Low latency for mission-critical and mission-non critical applications • Data prioritization (Bandwidth management) • Optimized transmission of specific applications such as video, and voice

    17. PROPOSED ARCHITECTURE- For University Extention Centre

    18. 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.

    19. Wireless Mesh Network

    20. 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.

    21. 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.

    22. Justification & importance of project • With WiMAX as the access network a wide coverage area of about 50 kms is possible. Hence access to the e-content 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.

    23. 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.

    24. 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.

    25. Time frame for development • Case study - 5 months • Procuring Equipment - 10 months • Installing - 4 months • Testing - 5 months • Implementation - 12 months • In addition, testing of the implemented system in real time environment would be done for a period of two years. Hence the total required time period is about five years approximately.

    26. NON RECURRING BUDGET

    27. RECURING BUDGET Total: Recurring + Non recurring = 1600lakhs.

    28. Estimated budget for implementing Soft switch:

    29.
