MOBILE NUMBER PORTABILITY - [email protected] - 10-04-2017

Mobile Number Portability
1.0 Introduction
Mobile Number Portability (MNP) allows subscribers to retain their existing mobile telephone number while moving from one service provider to another irrespective of the mobile technology or from one cellular mobile technology to another of the same service provider, in a licensed service area. This service has been introduced with the intent of creating a level-playing field for all operators by reducing the barriers to entry. As part of the transition, all operators are required to upgrade their network infrastructure so that all voice and data calls across operators are routed through a central mainframe which is maintained and run by the MNP service provider.
1.1 MNP in India:
In India, this service is expected to be operational by the mid of 2009. The DoT (Department of Telecom) has issued license to two global companies to implement the feature in two zones. Telecordia, the world s leading provider of MNP services has solutions deployed across none countries including the US, Canada, Egypt, Greece and South Africa has been issued with license for implementing MNP in north and west zone in India. Syniverse technologies, also a major player in voice and data solutions has been issued with license for south and east zones. The license issued in February 2009 quotes the companies to start service for metro cities by six months and other regions within twelve months. They will provide a central clearing house model for MNP in India. In INDIA only Operator based and service based number portability is launched and if success full would launch the other two also.
1.2 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 Service Provider 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 Long Distance Operator to the MNP service provider for dipping of each message. The service provider pays for the query response system database of
the 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.
1.3 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.
1.4 Lock-in period
The subscriber cannot opt to switch the network operator if the mobile connection is less than 3 months old. Additionally, if a number is already ported once, the number can again be ported only after 90 days from the date of the previous porting. The minimum period is required so as to enable the service provider to recover the customer acquisition cost.
2.0 Concept and Implementation:
In terms of concept, the MNP functionality is used only in MT transactions of voice and messaging. For MO transactions, the current flow scenario remains unchanged. Only for the MT functionalities, the mobile number has to be identified and the corresponding service provider has to be interrogated for optimal routing of the service.
There are two basic implementation of MNP.
2.1 Indirect Routing or decentralized or bilateral architecture:
This model works bilaterally between the donor and recipient service providers who are responsible for informing all others of the change. It would suit to markets with less number of service providers. Each provider will have a dedicated setup and comprehensive database of ported out and ported in subscribers. As the number of service providers increases, the bilateral approach becomes a great burden to all service providers involved in terms of time, cost and resources. FNR (Flexible Number Register) will help the service providers have the ported database in addition to the original HLR database.
2.1.2. Sample implementation of MNP in middle east:
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 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 point.
2.1.3 Technical details
A significant technical aspect of MNP (Mobile Number Portability) 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. Network operator makes copies of CDB and queries it to find out which network to send a call to. This is also known as All Call Query (ACQ) and is highly efficient and scalable. 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 calls to a number once it has been ported 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 out of that network will lose incoming calls to their numbers. 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. On 17 July 2007, Ofcom released its conclusions from the review of UK MNP and mandated reduction of porting time to 2 working days with effect from 1 April 2008. On 29 November 2007, Ofcom completed its consultation on further reduction to 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 1 September 2009.
In a decentralised model of MNP, a FNR (Flexible Number Register) may be used to manage a database of ported out/ported in numbers for call routing
In India as MNP is recently launched Number Port process takes 7 Days as of now. Which is the Highest Turn Around Time across World.
2.1.4 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.
2.1.5 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.

1. INTRODUCTION
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.
Number Portability will allow subscribers to change their service provider while retaining their old mobile number. Portability benefits subscribers and increases the level of competition between service providers, rewarding service providers with the best customer service, network coverage, and service quality.
Number portability is a circuit-switch telecommunications network feature that enables end users to retain their telephone numbers when changing service providers, service types, and/or locations. When fully implemented nation wide by wireline and wireless providers, portability will remove one of the most significant deterrents to changing service, providing unprecedented convenience for consumers, and encouraging unrestrained competition in the telecommunications industry.
Mobile number portability (MNP) requires that mobile telephone customers can keep their telephone number including the prefix when switching from one provider of mobile telecommunications 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.
2. HISTORY
The world s first country to introduce MNP was Singapore in 1997, followed by the
UK, Hong Kong and the Netherlands in 1999. As of 2003, a number of other countries,
Especially in Europe, require MNP.
The Telecommunications Act of 1996 (TA 96) tore down most of the significant barriers to unfettered competition in telecommunications. However, the inability of end users to retain their telephone numbers when changing service providers or types could potentially dissuade consumers from making such a change, threatening to hinder industry competition and growth. Congress addition of Section 251 (b)(2) to TA 96 addressed this obstacle by defining number portability, requiring that all carriers deploy it, and setting deadlines for implementation. FCC Docket No. 95-116 (In the Matter of Telephone Number Portability) and subsequent FCC orders and reconsiderations reinforced Congress mandate and set the machinery in motion to implement number portability.
The actions of both Congress and the FCC enabled consumers and businesses to choose new providers, services, and locales while retaining their phone numbers, thereby fostering competition in the telecommunications industry.
To ensure standardization across platforms for all participants, the FCC instructed the North American Numbering Council (NANC) to determine which number portability method to employ. Several options were investigated. The location routing number (LRN) method was chosen because it appeared to be the most efficient and is now successfully implemented in the wire line environment. The NANC then created the Local Number Portability Working Group (LNPA-WG) and empowered it to select the appropriate technology, create standards, determine operational processes, and develop and implement a deployment strategy. To fulfill its responsibilities, the LNPA-WG was granted the authority to convene appropriate subcommittees as needed. Subcommittees created include the National Number Pooling and Slow Horse groups, as well as the Wireless Number Portability subcommittee, which defines integration issues between the wireless and the wireline industries. NeuStar was named the Number Portability Administrator and operates the Number Portability Administration Center (NPAC).

I. Introduction
In the context of traditional circuit-switched telecommunications networks, number portability is the ability of end-users to
retain their telephone numbers when changing service providers, service types or locations. It is believed that when fully
and nationally implemented by both wireline and wireless service providers, number portability will remove one of the
most significant switching costs for consumers and will encourage competition in the telecommunications industry.
With the Telecommunications Act of 1996, Congress addressed the issue of number portability by formally defining it,
setting deadlines for implementation, and requiring all carriers to deploy it. To ensure standardization across platforms for
all participants, the Federal Communication Commission (FCC) instructed the North American Numbering Council (NANC)
to determine which number portability method to employ. The location routing number (LRN) method proved to be the
most efficient among alternatives and is the method now widely implemented in wireline environment. The sections
below discuss in detail number portability and LRN architectures.
II. Types of Number Portability
There are three types of number portability:
1) Service provider portability.
2) Location portability
3) Service portability
Service Provider Portability
Historically, all directory numbers in a given Numbering Plan Area - Central Office Code (NPA-NXX) were assigned to a
single telephone switch. By owning their customers' numbers incumbent local exchange carriers (ILEC) had significant
advantages over competitors. When customers wanted to switch service, they had to give up their number which imposed
on them inconvenience/switching costs. With the Telecommunications Act of 1996, FCC mandated that all numbers be
portable to all local exchange competitors (ILECs, CLECs, cellular, etc.). The Act defined service number portability as the
ability of end users to retain existing directory numbers (DN) at the same location as they change from one service
provider to another.
The introduction of service provider portability allows individual DNs in one NPA-NXX to be moved to a different switch. To
ensure that calls are routable to a portable number, FCC approved the concept of location routing number. Under the
number portability standard, each switch that hosts portable number is assigned a 10-digit LRN that is used to route calls
to that switch. All LNP-capable network elements have to maintain a list of NPA-NXXs that are considered portable. That
particular FCC mandate only refers to porting numbers within a given "portability domain" or rate center.
Location Portability
Location portability is the ability of users to retain existing DNs without impairment of quality, reliability, or convenience
when moving from one physical location to another. Location portability allows a given telephone number to be
associated with any network termination device, independent of location. It also allows customers to take their DNs when
they move to another geographic location outside of the original rate center. Although FCC does not address location
portability at this time, it leaves room for changes in the future.
Service Portability
Service portability is the ability of users to retain existing DNs without impairment of quality, reliability, or convenience
when switching from one service to another provided by the same telecommunications carrier. FCC is not addressing
service portability at this time and requirements for service portability are still undefined.

Introduction
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 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.

1.2 Types of Number portability
Number portability can be of different types.

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

1.2.2 Operator-based: This makes it possible for a mobile subscriber (or a fixed telephony
subscriber) 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 across
different mobile technologies Global System for Mobile Communications (GSM) and Code
Division Multiple Access (CDMA) based Wireless in Local Loop (WLL).

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

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

MOBILE NUMBER PORTABILITY - Akash.a.v - 10-04-2017

Mobile number portability (MNP) enables mobile telephone users to retain their mobile telephone numbers when changing from one mobile network operator to another.

General overview
This is implemented in many ways in the different parts of the world.
Recipient-Led' porting
In this standard, a customer wishing to port his/her number to contact the new provider (Recipient) who will then arrange necessary process with the old provider (Donor).
Donor-Led
In this method, a customer wishing to port his/her number must first contact the existing provider, and get a Porting Authorisation Code (PAC) which the customer must then provide to the recipient. Recipient continues the port process by contacting the Donor once the recipient has the PAC.

Technical details
The routing of calls or mobile messages (SMS, MMS) is the main issue on ce the mobile number has been ported. The best practice has been to use a a central database (CDB) of ported numbers. Then local copies of CDB is given to the network operators. From this CDB, they find out which network to send a call to. All Call Query (ACQ) is its alternative name and it is efficient and scalable.
Indirect RoutingIt is used in UK, and is inefficient and wasteful of the netwirk switching capacity. Here, the calls are still routed via the Donor network. The main disadvantage here is that if the Donor network develops a fault or goes out of business, the customers who have ported out of that network will lose incoming calls to their numbers.

Number Lookup Services
HLR query services may be used by the Service providers and carriers who route messages and voice calls to MNP-enabled countries for finding out the correct network of a mobile operator. Such services do the task of querying the operator's home location register (HLR) over the SS7 signalling network for finding out the current network of a mobile number.

The good news is that MNP is expected to be launched in India on 31 October 2010. Syniverese and Telecordia have already installed database servers for this.

Mobile Number Portability in India
The Indian Telecom market stands apart from other countries' market in the fact that it has the World s lowest call rate and fastest growing subscriber rate. Yet the a mobile penetration rate is as low as 37%. The Mobile Number Portability (MNP) was decided to be implemented in India by the TRAI (Telecom regulatory Authority of India), and it has been recently made available by the different networks in India.

The steps involved in the porting of a number to a different provider:
1) Customer making a written request to the recipient operator (RO) for porting along with other documents.
2)Verification of the documents by the RO.
3)RO asks the customer to send an SMS to the Donor.
4)The DO(donor operator) sends an automated SMS reply along with a unique porting code.
5)Customer submits the code to the RO.
6)The unique porting code is send to the MNP service provider.
7)the 90 day condition and no pending porting request on that number is verified by the MNPSP.
8)Details forwarded to the RO if verified.
9)criteria for porting are satisfied and inform MNPSP
10)a date and time of porting is fixed by the MNPSP which is withun 36 hrs of the clearance from RO&DO.
11)date & time informed to the subscriber through SMS.
12)instructions for disconnecting the number to the DO is sent by the MNPSP.
13)The DO release the number and report it to MNPSP.
14)MNPSP will inform the RO to activate the mobile number for that RO.
15)a corresponding Location Routing Number is assigned to it by the MNPSP and broadcasts the same to all the Access Providers and International Long
Distance operators..

The request for porting the number can be withdrawn within twenty four hours of making the application.
