INTRODUCTION
MOBILE NUMBER PORTABILITY:-
• Mobile number portability (MNP) enables mobile telephone users to retain their mobile telephone numbers when changing from one mobile network operator to another.
• Local number portability (LNP) for fixed lines, and full mobile number portability (FMNP) for mobile phone lines, refers to the ability to transfer either an existing fixed-line or mobile telephone number assigned by a local exchange carrier (LEC) and reassign it to another carrier.
• Mobile Number Portability (MNP) means the porting of mobile number. In simple language, you can change your present mobile service operator to a new one, but your present mobile number will remain the same. Thus your mobile number will not change in spite of the change of the service provider of your choice.
This article is about telephone number portability on landlines. For telephone number portability on mobile phones,Mobile number portability.
In Japan and Pakistan it is referred to as mobile number portability, (MNP). Wireless Number Portability is available in some parts of Africa, Asia, Australia, and most European countries including Britain.Canada,the United States are the only countries in the world that offer full number portability transfers between both fixed lines and mobile phone lines because mobile and fixed line numbers are mixed in the same area codes.Hong Kong government approved for fixed-mobile number portability.
Some cellular telephone companies will charge for this conversion as a regulatory cost recovery fee.
History:-
• Introduced as a tool to promote competition in the heavily monopolized wireline telecommunications industry (the First Report and Order on LNP and Number Pooling), number portability became popular with the advent of mobile telephones, since in most countries different mobile operators are provided with different area codes and, without portability, changing one's operator would require changing one's number.
• The first implementation of MNP starts in late 1990s with Singapore implementing the MNP (limited) functionality in 1997 followed by Hong Kong in 1999, Spain in 2000, Australia in 2001.
• In 1996 the US, LNP(Local number portability) was mandated by the Federal Communications Commission (FCC) in 1996 with the First Report and Order on LNP and Number Pooling. The mandate required all carriers in the top 100 MSAs (metropolitan statistical areas) to be "LNP-capable" and port numbers to any carriers sending a BFR (bona fide request). The ability to keep a number while switching providers is thought to be attractive to consumers. It was also a major point made by CLECs (Competitive Local Exchange Carriers) preventing customers from leaving ILECs (Incumbent Line Exchange Carriers), thus hindering competition.
• In the U.S., the FCC has mandated this in order to increase competition among providers.As of late November 2003, LNP was required for all landline and wireless common carriers, so long as the number is being ported to the same geographical area or telephone exchange.
• This latest mandate included carriers outside the top 100 MSAs that theretofore enjoyed a rural carrier exemption.
What is Mobile Number Portability (MNP) ?
The ability for a subscriber to maintain the same –phone number when switching service providers.The subscriber can move or “port” the phone number between service providers of the same nature (and in some cases between fixed and mobile operators).
GENERAL OVERVEIW OF MNP??
MNP is implemented in different ways across the globe:-
STEP1:- The international and European standard is for 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). This is also known as 'Recipient-Led' porting.
STEP2:-Once having received the PAC the Recipient continues the port process by contacting the Donor. This form of porting is also known as 'Donor-Led' and has been criticised by some industry analysts as being inefficient. 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.
STEP3:-This might lead to distortion of competition, especially in the markets with new entrants that are yet to achieve scalability of operation.
STEP4:-In India MNP launched recently which is Donor Led. Only the terminology is changed from PAC to UPC (Unique Porting Code).
Implementation Of MNP
The process of number porting consists of following steps:-
1. A customer sends number porting (NP) request to CNPMS.
2. CNPMS(CENTRAL NUMBER PORTABILITY MANAGEMENT SYSTEM) starts negotiation by sending NP request to Donor operator.
3. Donor operator accepts or rejects the NP request by checking his dues like payment of bills etc.
4. After getting confirmation in step 3, CNPMS negotiates with recipient operator to get confirmation.
CNPMS intimates the customer about the total time to be taken for NP.
1. Donor operator disconnects the service of the subscriber.
2. Recipient operator activates the service of the subscriber.
3. CNPMS sends service connects notice to all operators for updating their NP database(NPDB). Now customer can change his old SIM(or phone) with new SIM(or phone).
Subscription Termination Process consists of following steps:-
1. A Ported subscriber terminates his service from subscription network. Subscription network disconnects the number and retains the number for N days then returns the number to CNPMS.
2. CNPMS then returns the number to Number holder Network.
3. CNPMS sends the service disconnect Notice to all operators for updating their NP database(NPDB).

MNP Technologies/Portability schemes :-
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 four main methods to route a number whose operator has changed.
1. All Call Query (ACQ)
2.Query on Release (QoR)
3.Call Dropback
4.Onward Call Routing(OCR)
ALL CALL QUERY(ACQ):-
The operator that originates the call always checks a centralized database and obtains the route to the call. International best practice is via the use of a central database (CDB) of ported numbers. Network operators generally hold local copies of CDB and query it to find out which network to send a call to. This is highly efficient and scalable.
