  • * In IP networks, routing is based on stationary IP addresses, similar to how a postal letter is delivered to the fixed address on the envelope. A device on a network is reachable through normal IP routing by the IP address it is assigned on the network. The problem occurs when a device roams away from its home network and is no longer reachable using normal IP routing. This results in the active sessions of the device being terminated. Mobile IP was created to enable users to keep the same IP address while traveling to a different network (which may even be on a different wireless operator), thus ensuring that a roaming individual could continue communication without sessions or connections being dropped. Because the mobility functions of Mobile IP are performed at the network layer rather than the physical layer, the mobile device can span different types of wireless and wireline networks while maintaining connections and ongoing applications. Remote login, remote printing, and file transfers are some examples of applications where it is undesirable to interrupt communications while an individual roams across network boundaries. Also, certain network services, such as software licenses and access privileges, are based on IP addresses. Changing these IP addresses could compromise the network services.

    9. 9. Let’s Compare…<br />The basic comparison… <br />© Jubish Maathalath<br />6<br />
    10. 10. 1G (First Gen. Mobile Phones)<br />Developed in 1980s and completed in early 1990’s<br />1G was old analog system and supported the 1st generation of analog cell phones speed up to 2.4kbps<br />Advance mobile phone system (AMPS) was first launched by the US and is a 1G mobile system <br />Allows users to make voice calls in 1 country<br />© Jubish Maathalath<br />7<br />
    11. 11. 2G (Second Gen. Mobile Phones)<br />Fielded in the late 1980s and finished in the late 1990s <br />Planned for voice transmission with digital signal and the speeds up to 64kbps<br />2G was the digital handsets that we are used today, with 2.5G representing handsets with data capabilities over GPRS <br />© Jubish Maathalath<br />8<br />
    12. 12. 3G (Third Gen. Mobile Phones)<br />Developed in the late 1990s until present day<br />Services include: <br />Global roaming<br />Superior voice quality and video conference<br />Data always add–on services (e-mail, personal organizer, etc.)<br />Information for web surfing, music, news, corporate intranet, transportation service etc.<br />Purchasing – on-line shopping / banking, ticketing, gambling, games, etc.<br />© Jubish Maathalath<br />9<br />
    13. 13. 3G (Third Gen. Mobile Phones)<br />Transmission speeds from 125kbps to 2Mbps<br />In 2005, 3G is ready to live up to its performance in computer networking (WCDMA, WLAN and Bluetooth) and mobile devices area (cell phone and GPS)<br />© Jubish Maathalath<br />Conti….<br />10<br />
    14. 14. 4G(Forth Gen. Mobile Phones)<br />High performance<br />Interoperability and easy roaming<br />Fully converged services.<br />Low cost<br />Devices: more user friendlyinterface<br />Enhanced GPS Services<br />Scalability<br />Crisis-Management applications<br />© Jubish Maathalath<br />Fig: Sprint<br />11<br />

    17. 17. Protocol Stack for 5G Mobile Phones<br />The OSI Model<br />© Jubish Maathalath<br />14<br />
    18. 18. Open Wireless Architecture<br />These, OSI layer 1 and OSI layer 2, define the wireless technology.<br />For these two layers the 5G mobile networks is likely to be based on Open Wireless Architecture (OWA) which is proposed for 4G mobile terminals earlier.<br />© Jubish Maathalath<br />Physical & Data link Layer as..<br />15<br />
    19. 19. Network layer<br />The issue of IPv4, such as limited address space and has no real possibility for QoS support per flow, are solved here by using IPv6, traded with significantly bigger packet header.<br />All mobile networks will use Mobile IPin 5G.<br />Each mobile terminal will be FA (Foreign Agent), keeping the CoA (Care of Address) mapping between its fixed IPv6 address and CoA address for the current wireless network.<br />Different IP addresses for each of the radio interfaces will be CoA address for the FA placed in the mobile Phone.<br />© Jubish Maathalath<br />16<br />
    20. 20. Network layer Cont..<br />To maintain virtual multi-wireless network environment,<br />© Jubish Maathalath<br />Lower Network layer<br />WLAN<br />Lower Network layer<br />WiMAX<br />Lower Network layer<br />3G-LTE<br />Lower Network layer<br />4G<br />17<br />
    21. 21. Open Transport Protocol (OTP) layer <br />© Jubish Maathalath<br />Wireless networks differ from wired networks regarding the transport layer.<br />In all TCP versions the assumption is that lost segments are due to network congestion<br />In wireless, the loss is due to higher bit error ratio in the radio interface.<br />5G mobile terminals have transport layer that is possible to be downloaded and installed - Open Transport Protocol –(OTP).<br />18<br />
    22. 22. Application layer<br />Provides intelligent QoS management over variety of networks.<br />Provides possibility for service quality testing and storage of measurement information in information databases in the mobile terminal.<br />QoS parameters, such as delay, jitter, losses, bandwidth, reliability, will be stored in a database in the 5G mobile phone<br />© Jubish Maathalath<br />19<br />
    23. 23. Future Scope…. <br />With Wearable Devices<br />With SixthSense Technology<br />© Jubish Maathalath<br />20<br />
    24. 24. Let Me Conclude..<br />Adapts OWA proposed for 4G mobile terminals.<br />Network layer: provide all-IP connectivity in environment with plenty of wireless/mobile technologies as well as network and/or service providers<br />Open transport layer is proposed with aim to allow usage of wireless specific implementations of transport protocols.<br />Selection of different wireless technologies upon different QoS constraints (and cost constraints) for different services.<br />Maintain database which will keep statistical information.<br />Currently, the ongoing work is on the modules that shall provide the best QoS and lowest cost for a given service using one or more than one wireless technology at the same time from the 5G mobile phone.<br />© Jubish Maathalath<br />21<br />
