Mobile Number Portability

1. Mobile Number Portability By KunalOza

2. Number portability definition • Number portability enables a subscriber to switch between services, locations, or operators while retaining the original mobile number, without compromising on quality, reliability, services and operational convenience.

3. Types of number portability Number Portability Operator Portability (Between Operators) Location Portability (Between Service Areas) Service Portability (Between Wire line & Mobile) Fixed Number Portability Mobile Number Portability

4. Need of Number Portability • Convenience of customer to personalize the same number across the Operators, Locations and Services. (No age for your number.) • Subscriber’s benefit: • Better QOS, more features and services, better tariff plans for customers. • No cost incurred to notify the new contact details to the others( friends, family, business…..) • Operator ’s benefit: • Healthy competition and an opportunity to explore more services/features. • Operator with best QOS will gain the subscribers. • Introduction of innovative service.

6. MNP Terminologies related to network Donor Network Recipient Network Originating Network NPDB Originating Network : Network of the calling party Donor Network: Previous subscription of Called party Recipient Network : Present subscription of Called party NPDB : Number Portability Data Base (maintains portability database and provides routing instructions)

7. Operator B How It Works? NP Clearing house NPGateway Operator A NPGateway NP Clearinghouse • Clearinghouse is a centralized system that interconnects mobile operators • Defines number porting business rules and procedures • Utilize the system to implement number portability. • Provides statics and history for ported numbers Number Portability Clearinghouse • It is located at the Operator Premises • Interface towards the Clearing house • Manages the porting process • Interface towards operators OSS/BSS Number Portability Gateway Real-Time Network Query • Real time query response system for call routing to ported numbers • Setup by Clearing house for multiple operators

8. LRN + B-MSISDN LRN + Called Number Called Number Call Routing - All call query Whenever a call is originated, the Originating n/w will query its NPDB (Number Portability database) Recipient Network ORIG NW Database NPDB will acknowledge the query by adding a prefix LRN (Location Routing Number) to the called number. Based on the prefixed LRN the Originating n/w will route the call to the recipient n/w without involving the Donor network. Donor Network Originating Network ACQ (All Call Query Method) is called as direct routing, The Donor Network will not be part of the entire call flow

9. LRN codes circulated by TRAI

11. How to Switch - Rules: • The subscriber, who likes to avail this service, need to send a SMS from his mobile to 1900. • Once the customer sends SMS, he will be receiving a unique porting code from the current service provider. • Then he need to fill the application in a particular format and mention the new service provider, the customer would like to subscribe for. • The new service provider will collect the information about the user from the current operator. A time period of seven days will be taken for the complete transfer of mobile number to the network of the new mobile operator. • As a transformation charge for the new operator the subscriber has to pay the amount of Rs 19.

13. Regulatory guidelines TRAI has issued the “Regulation” for MNP in India which includes

14. Subscriber Eligibility Criteria Completed 90 days from date of activation Subscriber Eligibility Criteria Completed 90 days from the last porting

15. Operator Criteria: Rights & responsibilities of Donor Operator, Recipient Operator & Clearing House • Maintain records of all Port-out cases • If customer does not clear the dues, get the number deactivated thru Recipient Operator Donor Operator • Pay Per Post Transaction charges to MCH • Deactivate the number upon Donor Operator’s request Recipient Operator • Manage Porting Process • Resolve inter operator issues • Number reversal to “Range Holder” • Maintain records of all Ported numbers MNP Clearing House

16. Impact on Network due to MNP • Additional 25% signaling load will increase from the day1 of MNP launch. • Changes in tariffs • Monitoring and interception related issues. • Software development • number table would be modified.
