ABSTRACT

Mobile number portability allows a mobile subscriber to switch operators without changing his/her telephone number. This paper describes and analyzes mobile number portability routing mechanisms and their implementation costs. Cost recovery issues for number portability are discussed in this paper from a technical perspective. We note that rules for cost recovery also depend on business and regulatory factors that vary from country to country.

This paper examines the consequences of introducing mobile number portability (MNP). If the sole effect of introducing MNP is the abolishment of switching costs, MNP unambiguously benefits mobile customers. However, if MNP also causes consumer ignorance, as telephone numbers no longer identify networks; mobile operators will increase termination charges, with ambiguous net effect on the surplus of mobile customers.

Mobile number portability (MNP) requires that mobile telephone customers can keep their telephone number–including the prefix–when switching from one provider of mobile Tele communications services to another. In the absence of MNP, customers have to give up their number and must adopt a new one when they switch operators. As a result, customers face switching costs associated with informing people about changing their number, printing new business cards, missing valuable calls from people that do not have the new number, etc. Based on these considerations, many regulatory authorities have imposed mandatory MNP–or are about to require its introduction–so as to reduce customers’ switching costs, attempting to make mobile telecommunications more competitive The world’s first country to introduce MNP was Singapore in 1997.

This paper introduces the concept of number portability, explains its different types and benefits, and the technical, operational, and economic issues that might arise out of its implementation in India. The specific issues such as ensuring tariff transparency, the National Numbering Plan, and regulating porting charges, etc. have been raised and will need careful consideration.

Chapter 1Introduction

Portability gives users the ability to change his service provider without changing his number. This encourages the customer to switch, increases competition in the market, and the customer enjoys better quality of service and better tariffs while at the same time operators are burdened with extra costs of implementing MNP, higher churn rates and serious efforts to retain their high revenue generating customers.

Considering all the technical and administrative decisions taken, there is a distinct long term vision with some sound assumptions about the future growth of the Indian mobile industry and investments made from the operator’s side.All said, the implementation of MNP has been done with a lot of foresight and long term view for the mobile market although it would have been heartening to see some progress being made to facilitate number portability in the fixed networks also.

Mobile number portability allows a mobile subscriber to switch operators without changing his/her telephone number. Thispaper describes and analyzes mobile number portability routing mechanisms and their implementation costs. Cost recovery issues for number portability are discussed in this paper from a technical perspective. We note that rules for cost recovery also depend on business and regulatory factors that vary from country to country.

This paper introduces the concept of number portability, explains its different types and benefits, and the technical, operational, and economic issues that might arise out of its implementation in India. The specific issues such as ensuring tariff transparency, the National Numbering Plan, and regulating porting charges, etc. have been raised and will need careful consideration.

Mobile Number Portability offers the subscriber the flexibility to retain his telephone

number even when he switches to another operator in a service area. Number portability is

a feature that allows a mobile subscriber to use the same number across different service

providers. The person/user has the liberty to opt for any service provider without the time-

consuming exercise of letting the rest of the world know about the change of number Very

9


often subscribers do not switch to another operator even if the competitor is offering lower

tariff and better services because they do not want to change their number.

In a consultation paper issued in July 2005, TRAI said that subscribers and operators

would benefit from the introduction of the number portability system. As per TRAI, "In most

service areas in India, subscribers have a choice of operators, however, the subscriber's

inability to retain his telephone number when changing operators is an obstacle to

competition. Therefore, MNP will benefit subscribers and increase the level of competition,

rewarding operators with the best customer service, coverage, and service quality.”

TECHNICAL DETAILS

10


A significant technical aspect of MNP is related to the routing of calls or mobile messages (SMS, MMS) to a number once it has been ported. There are various flavours of call routing implementation across the globe but the International and European best practice is via the use of a central database (CDB) of ported numbers. A network operator makes copies of the CDB and queries it to find out to which network to send a call. This is also known as All Call Query (ACQ) and is highly efficient and scalable. A majority of the established and upcoming MNP systems across the world are based on this ACQ/CDB method of call routing. One of the very few countries to not use ACQ/CDB is the UK, where once a number has been ported, calls to that number are still routed via the donor network. This is also known as "indirect routing" and is highly inefficient as it is wasteful of transmission and switching capacity. Because of its donor dependent nature, indirect routing also means that if the donor network develops a fault or goes out of business, the customers who have ported numbers out of that network will lose incoming calls to their numbers.

Prior to March 2008 it took a minimum of 5 working days to port a number in the UK compared to 3.5 working days in Pakistan, 2 hours in USA, as low as 20 minutes in the Republic of Ireland, 3 minutes in Australia and even a matter of seconds in New

Zealand. On July 17, 2007, Ofcom released its conclusions from the review of the UK MNP and mandated reduction of porting time to 2 working days effective April 1, 2008. On 29 November 2007, Ofcom completed a round of consultations on further reduction of porting time to 2 hours along with recipient-led porting and mandated that near-instant (no more than 2 hours) recipient-led porting be implemented by no later than September 1, 2009. However, in early 2008 Vodafone UK appealed the Ofcom statement before the Competition Appeal Tribunal (CAT), and on September 18, 2008, CAT ruled in favor of the appeal, returning the matter back to Ofcom for reconsideration. On July 8, 2010, Ofcom issued a final statement, retaining the donor-led process, mandating a two-hour PAC release time, and reducing the porting time from two to one working day.[1]

Chapter 4 MNP in India

1.1 Charges relating to porting

(a)Per Port Transaction Charge is payable by the Recipient Operator (the operator, where the subscriber is willing to port his number) to the MNP ServiceProvider for processing the porting request of a mobile number – TRAI has fixed this charge at Rs 19.(b) Dipping Charge is to be paid by a service provider or an International

12

http://en.wikipedia.org/wiki/Mobile_number_portability#cite_note-1

http://en.wikipedia.org/wiki/Ofcom



http://en.wikipedia.org/wiki/New_Zealand


Long Distance Operator to the MNP service provider for dipping of each message. The service provider pays for the query response system database ofthe MNP service. Key drivers for dipping are total number of calls, missed calls and SMS. The Dipping Charge is left to mutual negotiation between the telecom service providers and the respective MNP service providers. © Porting Charge is due by the subscriber to the recipient operator for porting of the mobile number. The amount to be paid by the subscriber shall not be more than the Per Port Transaction Charge that is Rs 19/-. Operators are free to charge any amount less than or equal to this charge.

1.2 Number Lookup Services

Service providers and carriers who route messages and voice calls to MNP-enabled countries might use HLR query services to find out the correct network of a mobile phone number. A number of such services exist, which query the operator's home location register (HLR) over the SS7 signalling network in order to determine the current network of a specified mobile phone number prior to attempted routing of messaging or voice traffic.

1.3 Porting time

The porting time is fixed at 7 days for complete transfer of mobile number to the network of the new mobile operator with a maximum downtime of 2 hours. For Jammu-Kashmir, Assam and the North East, the porting time can be extended to 15 days.

Who can avail MNP facility?

Any Mobile Subscriber, irrespective of Pre-Paid and Post-Paid (GSM / CDMA), can switch over to other Service Provider. Eligibility conditions for porting are as follows:-

There are no outstanding payments due from the subscriber by way of pending bill or bills, as the case may be, issued as per the normal billing cycle but before the date of application for porting

The porting request has been made after the expiry of a period of ninety days from the date of activation of a new connection or from last porting;

No request for change of ownership of the mobile number is under process;

Subscriber has applied for porting within LSA (Licensed Service Area)

13


Porting of the concerned mobile number has not been prohibited by any Court of Law

The unique porting code mentioned in the porting request matches with the unique porting code allocated by the Donor Operator for the mobile number sought to be ported

The subscriber has complied with exit clause for the present connection.

Chapter 5 APPLICATIONS AND IMPACT OF MNP

The various applications are as follows:-

Those who do not yet know the mobile number portability (MNP) is a service whereby a mobile subscriber can move from one operator to another without having to change his mobile number. For example, you can choose to select services Voafone on your Airtel number or vice versa, courtesy MNP. As posted earlier, the mobile number portability already deployed for cellular customers in Rohtak, Haryana and will progressively be implemented in other countries that covers the entire nation, January 20, 2011. 5.

14


Mobile number portability is implemented in different ways across the globe. The International and European standard is for a customer wishing to port his/her number to contact the new network (recipient), which then sends the number portability request (NPR) to the current network (donor). This is known as "recipient-led" porting. The UK and India are the only exceptions to implement the donor-led system. The customer wishing to port his/her number is required to contact the donor to obtain a Porting Authorisation Code (PAC), which is then showed to the recipient network to proceed. Once having received the PAC the recipient continues the port process by contacting the donor. This form of porting is known as "donor-led" and has been criticised by some industry analysts as being inefficient, though prevents MNP scams. It has also been observed that it may act as a customer deterrent as well as allowing the donor an opportunity of "winning back" the customer. This might lead to distortion of competition, especially in the markets with new entrants that are yet to achieve scalability of operation.

IMPACT of Mobile Number Portability :

The main reasons for porting out have been reported to be network/coverage issues, tariff issues etc.

The major steps taken / being taken by BSNL to retain the existing customers and add new customers in the competitive environment are as follows:-

(i) Forgoing porting fees from subscribers coming into BSNL network.(ii) BSNL has formed Special Cells in its circles to contact customers and address their grievances.(iii) Introduction of Competitive tariff plans.

(iv) Additional incentives for distributors and retailers. The major steps taken / being taken by MTNL to retain the existing customers and add new customers in the competitive environment are as follows:-

(i) All exchanges have been made Digital to improve service quality.(ii) Rehabilitation of outdoor network to reduce fault rate.(iii) Optimization of mobile network to improve upon the coverage and capacity. (iv) Opening of new Sanchar Haats.(v) Introduction of Competitive tariff plans.(vi) In Mumbai, MTNL has waived off MNP porting charges of Rs.19 for porting in customers

How can I port to a new Mobile Service Provider?

The salient steps involved are given below:-

The subscriber will have to visit the new Mobile Service Provider's Service Centre or Authorised Dealer to request for porting of his/her mobile number. Fill in a Service Registration Form and pay the porting fees for processing.

The subscriber will have to send a SMS to Donor Operator to request for UPC (Unique Porting Code) using short code 1900 from the mobile number which is sought to be ported.

To avail the MNP service the subscriber needs to send SMS PORT followed by 10 Digit Mobile Number to 1900 and they will get UPC porting code by SMS (e.g. PORT XXXXXXXXXX and send it to 1900)

Upon receipt of the SMS, the Donor operator shall forthwith send back a reply SMS containing a unique porting code through an automated system. Subscriber will fill the UPC in the Application form for porting.

16


In case the subscriber's Caller Line Identification does not match with the ten digit mobile number, UPC shall not be allotted but a message shall be generated to inform such subscriber that the CLI does not match with the mobile number.

UPC allocated to a subscriber shall be valid for a period of fifteen days from the date of request or such time till the number is ported out, whichever is earlier.

For all service areas except Jammu & Kashmir, Assam and North East licensed areas the validity for the UPC shall be for a period of thirty days from the date of request or till such time the number is ported out, whichever is earlier, irrespective of number of requests the subscriber makes.

The subscriber will be issued a new SIM card by the new service provider.

Upon approval of porting request, the new Mobile Service Provider will inform the subscriber

Issues with this type of routing: • Routing to the ported user is indirect and possibly costly, because additional transit charges, interconnect charges, and/or extra conveyance costs may be generated even when the originating provider is the same as the terminating recipient provider.

• For the donor network, billing associated with ported and non-ported numbers cannot be differentiated easily.

• If the donor network uses a small, non-high-performance database, increased call setup time for ported numbers is inevitable.

•Due to the dependence on the donor network, the receiving network cannot serve the ported user reliably, because it has no control over the quality of service on the donor network.

• If the donor provider discontinues its operations or is experiencing a network failure, the ported subscribers cannot be reached even if they ported numbers years ago. This is a growing concern due to the increasing number of failures and the high cost to put these subscribers back in service.

Types of Number portability :

Number portability can be of different types.

17


1.2.1 Location-based: This enables a mobile subscriber to use the same number whenshifting from one geographical area to another.

1.2.2 Operator-based: This makes it possible for a mobile subscriber (or a fixed telephonysubscriber) to shift from one mobile (or a fixed) service provider to another in the same area and retain his original number too.

1.2.3 Service-based: Enables subscribers of a company to use the same numbers acrossdifferent mobile technologies — Global System for Mobile Communications (GSM) and CodeDivision Multiple Access (CDMA) based Wireless in Local Loop (WLL).

1.2.4 Convergence-based: Allows usage of the same number while shifting from fixed tomobile telephony.

1.2.5 Total number portability: Enables usage of the same number across differenttechnologies, geographical regions and national boundaries and is the ultimate aim of numberportability. It will also be the most difficult to implement and would require a collaborated efforton the global scale among different service providers. It will be a combination of different typesof portability options.Number portability when used to transfer numbers from one service provider to another is calledMobile Number Portability. MNP is already being used in developed markets, which are matureand have a much higher teledensity.

In one of the countries of middle east, the MNP service is implemented in bilateral architecture. There are two operators available in the country and each have their own customized system for handling the MNP database. Whenever a customer wants to change his service provider, he visits the recipient provider and initiates a request to port in the subscription with the recipient provider.

The recipient party then coordinates with the donor party for porting the number.During the process, the donor deletes the number from its HLR database and updates the number in its FNR – ported out list. Similarly the recipient party updates the number in its HLR database and FNR – ported in

18


list.Coming to the MT transactions, there are two possible options,

1. Call from same PLMN: As both the service providers have the complete list of Ported out and ported in numbers, the originating MSC will route the call either to its own network or to other network based on available database.

2. Call from outside the PLMN: As the originating network need not to be aware of the MNP functionality, it will route the call based on the number series database available with it. The recipient network will make further analysis for routing of the call by following the procedures mentioned in previous p

The UK telecoms regulator Ofcom completed its extended review of the UK MNP process on 29 November 2007 and mandated that ACQ/CDB be implemented for mobile to mobile ported calls by no later than 1 September

2009, Prior to March 2008 it took a minimum of 5 working days to port a number in the UK compared to 2 hours only in USA, as low as 20 minutes in the Republic of Ireland, 3 minutes in Australia and even a matter of seconds in New Zealand.

Which is the Highest Turn Around Time across World

Mobile Number Portability (MNP) is going to be fully implemented from tomorrow, January 20, 2011 throughout India. Now, you can choose the mobile operator keeping your mobile number intact. From tomorrow onwards, no need to worry about the poor connectivity or less options to choose from your current provider. Change your service provider keeping your mobile number same. Jump from GSM to CDMA and vice versa.

Affordable & Convenient

Porting Charge only up to Rs. 19/- Porting time: 7 working days (15 working days in case of Jammu & Kashmir,

Assam and North East service areas)In the interest of consumers TRAI has also specified that service disruption timeshall not exceed 2 hours, that too during night time.

Request for Porting

Contact the new mobile service provider to whom you want to port your mobile number.

Obtain Customer Acquisition Form (CAF) & Porting Form. Read the eligibility and other conditions carefully. If eligible, obtain ‘Unique Porting Code‘ by sending an SMS from the mobile

number you want to port to the number ‘1900’ with text ‘PORT‘ followed by space followed by your 10 digit mobile number you want to port.

Fill up the CAF and Porting Form.

20


Submit the duly filled Porting Form and CAF along with requisite documentary proof to the mobile service provider.

If you are a post paid subscriber, submit a paid copy of the last bill issued along with Porting Form and CAF.

Obtain new SIM card from the new service providerYou can withdraw your porting request within 24 hrs of applying.

Activation of ported number:

Your new mobile service provider will intimate you the date & time of porting on your mobile phone.

Replace the old SIM with the new SIM provided by your new mobile service provider after the specified date and time.Eligibility and Other Conditions

You are allowed to move to another mobile service provider only after 90 days of the date of activation of your mobile connection or from the date of last porting of your mobile number, which ever is applicable.

You are allowed to change mobile service provider within the same service area only.

If you are a postpaid subscriber, please ensure that you have paid all the dues as per your last bill (You will have to sign an undertaking in the Porting Form also).

If you are a Pre-paid Subscriber, please note that the balance amount of talk time, if any, at the time of porting will lapse.

Indian telecom sector has come a long way in achieving its dream of providing

affordable and effective communication facilities to its citizens as envisaged in NTP 99. As a

result, common man today has access to the most needed facility. Larger efforts are continuously

being made to provide universal service to all uncovered areas including rural areas. The reform

measures coupled with the proactive policies of the DoT have resulted in an unprecedented

growth of the telecom sector. Today, the Indian telecommunication network with over 270

million connections is the third largest in the world and the second

largest among the emerging economies of Asia.

India of late has emerged as an important player in the telecom industry worldwide and it

is the endeavor of the Indian government to facilitate further growth of this vital industry as it is

not just the growth of the sector but it has a ‘multiplier effect’ on the entire economy. During the

past few years the sector witnessed high growth rates. Since 2004, the number of telephones

grew at a rate of 40%. The sector continued to register significant growth

during 2007-08. The current addition of about 8 million lines per month puts the

telecommunication sector on a strong footing to achieve the target of 500 million connections by

2010. Sourced from www.dot.gov.in annual report 2007-08 Network expansion has been one of

the major objectives for the DoT and they have been working successfully towards that goal.

22


The total number of telephones reached 272.87 million on December 31st, 2007 as

compared to 190 million a year ago. The teledensity has shown a sustained increase in the last

few years as shown in the following graph. Ithas increased from 16.83% in 2006 to 23.89% in

2007. Though these numbers are low when compared with those of the developed economies,

the rate of growth in the last few years and the projected growth rates in this sector suggests

that we could reach the international standards sooner rather than later.

4. Effectiveness of Implementation

During the initial phase of the discussion, the operators disagreed mainly on two points:

1. Implementation of MNP prior to FNP.

2. Timing for the implementation of number portability

The arguments given in favor the first reason were:- Looking at implementation of number

portability in other countries, everywhere

FNP was implemented prior to MNP - Compared to Fixed service sector, level of competition in

the mobile service sector is pretty high already. Number portability in the fixed service sector

would do well, because even after 10 years of privatization almost 90% of the market share is still

with the incumbents (BSNL and MTNL).

The DoT and TRAI refuted these arguments using the following points: - Most of the

countries implemented FNP ahead of MNP, because at that time in those countries mobile

23


services was still in the nascent stage. However in India mobile network is growing exponentially

whereas fixed network growth is marginal. - Incumbents in the fixed service line have legacy

networks with technical/feasibility limitations for accommodating FNP. Huge investment costs

would be required as compared to mobile networks having start-of-art technologies. Therefore

MNP would be easier to implement than FNP. - Non availability of directory and directory

enquiry service for mobile numbers. –

The existing numbering for fixed phones in India is SDCA1 based. Therefore if FNP is

implemented it will be limited to SDCA level only until numbering scheme is modified. - Apart

from the incumbent, other players are not present in all SDCA’s in a circle, hence customers in

such SDCA’s would not have an option to switch even after the implementation of the service.

Interaction with personnel on both sides of the argument, the personal view of the author is that

there is logic on both sides of the argument. The operators feel hard done by, especially because

FNP implementation has been scrapped/ delayed for later. The TRAI/DoT could have explored

more cost effective implementations for FNP which include localized databases within SDCA’s

instead of ALL-CALL-QUERY as is the case for MNP.

Chapter 6 ADVANTAGES

Advantages of Mobile number Portability:

The best thing of this is that the service can be changes easily with the retain of the previous number and help a subscriber to get in touch with its friends and colleagues.

As far as the pricing and the stickiness of the post paid connections in concerned, it will be quite reasonable for the customers and the call rates will be reduced because it will put pressure on the post paid companies which in turns develops a competition among the companies and allows them to reduce their calling rates.

The new tariff plans will be introduced for the customers who are using this new service with some high speed value added services that provides the video calls and other so many facilities for the new customers.

It will improve the quality of service for the customers by storing the details of the messages and contacts which is there in the previous SIM card by sending a request to the new service provider through the help of application form whose information is given below in switching operator section.

25


Chapter 7

LIMITATIONS

Limitations of Mobile number Portability:

This can definitely made a huge impact on the post paid services provided the companies with the unique VIP mobile numbers but extend the choices and options of the service users or subscribers.

It is applicable with in the circle of that service and you cannot use the mobile portability number feature in case you wants to shift from one city to another.

All the pre-paid users will lost their balance if you have got some balance in their accounts so it is better to spend your all balance before switching your network.

You are not provided with the option to switch operator and retain number if you have been using that service for the less than three months.

26


Chapter 8

CONCLUSIONS

Mobile number portability is the facility which provide to customer to change their operator without changing their number. so tha is very beneficial to customer so customer to can use that is facility to avoid such type of operator problem i.e call drop, network issue etc. So that is very important process to customer
