  1. MOBILE NUMBER PORTABILITY BY SHARATH.R

  2. WHAT IS MOBILE NUMBER PORTABLITY MNP

  3. Types of MNP • SERVICE OPERATOR PORTABILITY • LOCATION PORTABILITY • SERVICE PORTABILITY

  4. SERVICE OPERATOR PORTABILITY • retain the same geographic number when changing from one operator or service provider to another. • Currently being used in INDIA

  5. LOCATION PORTABILITY • Customer to retain the same geographic number when moving from one location to another • Location portability would allow customers to take their number when they move to a geographic location outside of the original rate center

  6. SERVICE PORTABILITY • Retain the same geographic number when changing from one service to another • From basic telephony to ISDN(Integrated Service Digital Network)

  7. Architecture

  8. TECHNICAL ASPECT • NUMBER POOLING • NUMBER PORTABILITY DATABASE • ROUTING MECHANISM

  9. NUMBER POOLING • Due to shortages of numbering resources FCC had approved a National Number Pooling plan for network resource optimization • The concept of pooling is based on the fact that whole blocks of telephone numbers, held by some service providers, are not assigned or in service. Pooling allows these currently unassigned blocks of numbers to be reassigned to other service providers in need of numbers, as they request and show need. • As that supply depletes, service providers will request additional numbering resources from the industry inventory maintained by the Pooling Administrator

  10. NUMBER PORTABILITY DATABASE • The number portability database (NPDB) keeps track of the ported numbers and their respective service providers • The NPDB can be either centralized or distributed • In the centralized model, there exists a single reference database • In the distributed model there exist multiple databases, each containing subsets of the total data, e.g. only the numbers assigned to particular service provider

  11. ROUTING MECHANISM

  12. All Call Query • The Originating Network receives a Msg/call from the caller and send a query to a centrally administered Number Portability Database (NPDB) • The NPDB returns the routing number associated with the dialed directory number. • The Originating Network uses the routing number to route the call to the new serving network.

  13. Onward Routing • The Originating Network receives a call from the caller and routes the call to the donor network • The donor network detects that the dialed directory number has been ported out of the donor switch and checks with an internal network-specific NPDB • The internal NPDB returns the routing number associated with the dialed directory number • The donor network uses the routing number to • route the call to the new serving network.

  14. Call Dropback • Receive call to the donor network.  • The donor network detects that the number has been ported out of the donor switch and checks with an internal network-specific NPDB • NPDB returns the routing number • The donor network releases the call by providing the routing number • The Originating Network uses the routing number to route the call to the new serving network

  15. Query on release • A call from the caller and routes the call to the donor network. • The donor network releases the call and indicates that the dialed directory number has been ported out of that switch • The Originating Network sends a query to its copy of the centrally administered NPDB • The Originating Network uses the routing number to route the call to the new serving network

  16. Portability process

  17. Porting process

  18. How to change operator

  19. CHALLENGES • Customer’s value added services will be lost • What for fixed lines? Local number portability includes some thing as Standard Transfer, Like-for-Like Transfer. These are really challenging to setup and bill accordingly.

  20. BENEFITS OF MOBILE NUMBER PORTABILITY • MNP  gives best benefit to the customer, as they do not have to change their number, eliminating a great headache of communicating the new number to all his/her important contacts • MNP will keep all the mobile network providers on an alert • Network provider will really treat the customer as a king. You will get lightning response and great customer service from your existing mobile network providers

  21. ADVANTAGES DIS ADVANTAGES • Can retain existing mobile number. • Just for a small fee of    19/- • You can switch from GSM to CDMA and vice versa • Change in location having same number • cannot switch again for the next 90 days. • Change in hand set when change in platform

  22. FUTURE IMPLEMENTATION • switch from one geographic location to other i.e. having one number across the country. Example if your number is registered in Karnataka you can switch to a service provider in Gujarat • Not loosing balance on prepaid cards.  • Changing from CDMA-to-GSM or vice-versa,without change in handset • If the customer has extra services, like caller tune, GPRS, voice mail and others alike, then these services will not be lost

  23. CONCLUSION • Number portability removes important barrier to increased competition in the telecommunications sector. • As such, it brings challenges and opportunities for old and new telecommunications providers • To be successful in the competitive telecommunications environment, carriers have to carefully analyze their network and administrative infrastructures, select the best number portability solution for their needs and exploit the benefits of increased customer choice that NP provides
