INTRODUCTION OF MNP

Mobile Number Portability (MNP) allows Mobile subscribers to change their service provider while retaining their subscriber number. Portability benefits subscribers and increases the level of competition between service providers, rewarding those operators having better customer service, network coverage, and service quality.

FEATURES OF MNP

There are three basic feature of Mobile number portability:

Location portability. Service portability. Operator portability.

LOCATION PORTABILITY

The ability of a subscriber to retain an existing Mobile number, when shifting from one circle to another keeping the operator same as before.

SERVICE PORTABILITY

It is the ability of a subscriber to retain the existing Mobile number when changing from one service to another service, say from GSM to CDMA services.

OPERATOR PORTABILITY

This is the ability of a subscriber to retain within the same service area, an existing Mobile number even if they change from one service provider/operator to another.

MNP IN INDIA(EXPECTED AT THE END OF 2009)

To give mobile phone users or end users the ability to change operators while retaining their existing numbers

Three basic types of number portability: service, location and operator portability

Regulator to play an important role. Neutral third party shall establish logically

centralized database with not more than 5 regionally located databases.

•MNP is finally set to hit the Indian market by the end of 2009.

•Once operators become replaceable and number portability becomes a reality, two things would come under focus-service quality and value added services provided by operators.

•Some operators are really excited about this model, on the other hand, VAS players believe that MNP will have some positive impact on the VAS ecosystem.

EXPECTED OUTCOMES POST MNP(Operator’s & VAS provider’s perspective)

•This would make the entire system very interesting and competitive wherein performance would be the key player.

•MNP would affect the revenue sharing pattern between operators and VAS players, because operators would be ready to pay high prices for exclusive content in order to attract more and more customers to their brand.

•Loss of branding .

•It will not only allow subscribers to retain number while changing operators, but also to retain number while switching over from CDMA to GSM platform or vice versa.

•More choice means improved customer service and reduced cost to the subscriber

•Introduces competition in saturated markets

From Customer’s Perspective:

• Results in more effective use of numbering resources

• A win-win situation for a customer

• Handsets ‘locked’ to networks will incur additional costs

TERMS USED IN NUMBER PORTABILITY

•Donor network •Originating network •Recipient network•Database•Routing number

TECHNICAL SOLUTIONS

Deciding between different technical options requires consideration of a whole range of issues: including interconnection between networks , call charging arrangements , operational support system modifications , routing arrangements in the National Numbering Plan etc.

In order to arrive at a suitable technical solution,there are broadly two methods available for routing of calls in a mobile number portability environment:

Direct routing(also known as All call query).

Interdependent routing.(Three types)

INTERDEPENDENT ROUTING TYPE Onward routing: The donor network identifies the correct

terminating mobile network and routes the call onward to that network .

Call drop back: The Donor network after confirming that

the number is ported, releases the call back to the originating network together with information identifying the correct terminating network .

INTERDEPENDENT ROUTING CONT…

QUERY ON RELEASE : The Donor network after confirming that the

number is ported, returns a message to the originating network indicating that the number has moved. The originating network then queries a database to obtain information identifying the correct terminating network.

DATABASE MANAGEMENT

The various technical options related to the implementation of MNP mentioned above involve the use of databases that contain routing information. The databases can be centralized or distributed.

LEVEL OF CENTRALIZATION OF DATABASE

The database at circle/metro-wise is easier to implement from the angle of scalability, connectivity by the networks of the operators. The cost of connectivity to the database will also be less in this approach.

The national level database could be a single point of contact to ported numbers. However, the Implementation of such a nation-wide database raise concerns regarding scalability, performance and availability.

COMING TO THE CONCLUSION OF ROUTING..

The Direct routing solution / All Call Query is perceived as a long-term solution for number portability whereas Call Forwarding solution was adopted initially when the estimated number of portings are less.

The key advantage of Direct routing (or All Call Query) is that it does not increase network congestion between originating operator and the donor operator as the ported calls are directly routed to recipient network.

CONCLUSION CONTINUES

this method eliminates dependence on the donor network operator, thereby providing the ability to maintain portability in the event of donor network operator’s failure or exit from business. Therefore, direct routing is considered as more optimized with more efficient call routing.

IMPLEMENTATION IN INDIADoT has issued mobile number portability details and the first phase will be rolled out in Delhi, Mumbai, Kolkata and Chennai by end of, 2009.

• From a consumer standpoint, the entire process of porting a number should not take more than two (2) working days, with a two (2) hour break in service. Rs 300 will be charged.

•More than 90% of Indian mobile users are on prepaid connections and do not have number loyalty (~churn rate of 4% on monthly basis)

•Operators will add a lot more nuances (for instance, time bound etc) to ensure that switching cost/experience is fairly high (as ARPU is sliding).

•. The service providers are not keen on its introduction as that would require a substantial investment in upgrades to the routing and the billing mechanisms.

•The cumulative losses for the Indian GSM mobile players would be around Rs 8,000 crore and increased investments could mean more bad debt.

WHAT IS CLEARINGHOUSE?

The Centralized Clearinghouse is a message processing system through which service providers communicate using the same set of rules for handling porting requests and exchanging information required for porting numbers.

This centralized clearing house will be managed by third party to avoid conflict of interest.

The Number Portability Database will have the mobile numbers of all mobile users.

All mobile service providers will then link their networks with that of the MCHAs(Mobile Number Portability Clearing House Administrator) and NPDB(National Portability Database).

ROLE OF CLEARINGHOUSE

National Number Portability Clearing House a regulatory body responsible for managing port-in/out numbers across the operators in India.

It maintains a database with Port-In/Out information across the country / operators.

It also maintains historical trail of porting for audit trail.

This database is pushed / pulled into ‘Reference Database’ also called ‘Routing Database’ which will assist network elements (MSC) to direct each call to their respective telecom operator (servicing that number).

ROLE OF CLEARINGHOUSE

PROCESS

Subscriber contacts new operators and asks his number to be ported

New operator submits number port request to clearing house

New operator will charge 75-200 rupees porting charge.

The clearing house informs the old operator Clearing house informs all operators that the

number is ported Number Portability Database will have all mobile

numbers.

MCHA IN INDIA

Department of Telecommunications (DoT) has chosen two providers –Syniverse Technologies and Telcordia Technologies - for the implementing MNP.

 Both the companies will provide solutions for 11 circles each of the total 22 circles in the country.

Syniverse:-North & West. Telcordia:-South & East.

MNP IMPLEMENTATION FACTORS

How high is demand for MNP from both subscribers and operators?

How big is market size? Is it below the minimum threshold market size?

What is the level of competition? How mature is the market?

What kind of pricing model is in place? Will MNP spur further competition? How strong and independent is the regulating

body?
