2. Mobile number Portabillity

3. CONTENT What is MNP….? Types of Number Portability Component of MNP MNP implementation MNP working Benefits Problem Future aspects Conclusion

4. What is MNP??????  Mobile Number portability (MNP)  Enables mobile subscribers to change their service providers  Their location without having to change their existing phone numbers.

5. Types of Number Portability Location service operator

6. Component of Number Portability  Service Platform  Server  Central Reference Database(CRDB)  Passive  Active

7. Central Reference Database(CRDB) Functionality Reference database for the ported numbers Storage of present and historical information related to ported numbers Message relay porting confirmations porting requests Message Validation Message order and parameter contents are validated before relayed or broadcast. Message Flow Control flow of administrative messages between the service providers and network operators connected to the CRDB.

8. MNP implementation 1. ALL-CALL-QUERY METHOD The originating network first checks the location of the dialed number in the central database and then routes the call directly to the recipient network (the network where a number is located after being ported).

9. 2. QUERY-ON-RELEASE  The originating network first checks the status of the dialed number with the donor network (the initial network where the number was located before ported).  The donor network returns a message to the originating network identifying whether the number has been ported or not.  The originating network then queries the central database to obtain the information regarding the recipient network and routes the call directly to the recipient network.

11. 3.ONWARD ROUTING (CALL FORWARDING). Originating network connects to the donor network. If the dialed number has been ported, the donor network itself routes the call to the recipient network.

12. Continue….  The central agency checks with the SP-A. This could include verifying whether the customer has paid all dues any completed pending commitments. The SP-A can also choose to check with customer to verify the authenticity of the request. However SP-A upon getting the instructions from Central agency need to finish the portability in one hour.  In case, the customer wants to cancel the request, she can do it within 24 hours from applying. In that case, she can’t reclaim the dipping charge.  Once into the new SP-B, the customer can’t move out and retain the number at the same time for the next three months.  The entire process may take more than 4 days to a maximum of 6 days.

13. 4.Call-drop back. Donor network checks whether the number is ported and if it is, it releases the call back to the originating network together with information identifying the correct recipient network. The originating network then routes the call to the recipient network.

14. MNP Process... The process works as follows -  A customer who has a mobile number connection active for three months (90 days) with Service Provider SP-A, wants to use new service from Service provider SP-B. She wants to retain her current mobile number.  She goes to the SP-B. Fills up forms, giving him enough details.  SP-B goes to the central agency. Either with one request or with bulk of them. Queries for more details. This process is known as “Dipping”. The customer can be charged for this. The dipping charge may not be more than Rs 19 per request per customer.

15. Bulk Process Recipient Service Provider Donor Service Provider Co-orporation Dealer 1 2 request port request communicate details electronically Issue Porting Authorisation Code (PAC) approach RSP with PAC respond to port request Inform & Negotiate 3 4 5 6 7 request response

17. Benefits BENEFIT OF MNP IN INDIA TO USERS: will not have to change the number. save money by having the best plan you like. BENEFIT OF MNP IN INDIA TO OPERATORS: Savings in expenses for reserving a number-series: Less struggle for newcomers: BENEFIT OF MNP IN INDIA TO GOVERNMENT: More competition means more revenue More investment in market:

18. Problems of Mobile Number Portability in India to users The switching from one operator to another requires you to pay Rs.19 You still have to follow the same old procedure of going to a shop, getting a new SIM It takes time for the switch to take place.

19. Problems of Mobile Number Portability in India to operators Technology change More competition with other companies Underlying network changes

20. Problems of Mobile Number Portability in India for Government More competition to BSNL Loss due to dropdown in number of mobile numbers No More number series reservations

21. Future aspects  The future seems to be bright for this technology in India. The reason for being so is that currently, according to the government statistics, about 68% of all mobile customers change their mobile phone number at least once in a year.  When Mobile Number Portability in India is complete, the number will drop significantly and only those people will change the numbers who really want to disconnect the mobile service or want to become anonymous again.

22. Conclusion  The MNP process is relatively new to India but holds lots of scope. With the revolution of mobile telephony sector in India, the subscriber base has grown by leaps and bounds over the past decade.  It can also lead to lots of errors like customer dissatisfaction, misalignment between the old and new service operator, loss of revenue and negative publicity. Hence proper infrastructure needs to be in place for it starts in India.
