Introduction What is Mobile Number Portability?
– It enables the subscriber to switch between services, locations and
operators while retaining the original number.
– This scheme provides freedom and convenience for customers to get
the best services.
– MNP is abbreviation of Mobile number portability.

Types of MNP• 1.Operator Portability:- From one operator to another e.g. BSNL TO IDEA ,AIRTEL TO
VODAFONE and vice-versa etc.• 2.Location Portability:-
From one location to another • 3.Service Portability:-
From one service to another e.g. prepaid to postpaid.

MNP Guidelines I. A mobile number can be ported only if it is still in operation.II. Pre-paid, GSM , CDMA numbers shall be portable. However, any credit on the
card will be lost.III. Calling Line Identification Presentation (CLIP) shall be portable.IV. Connected Line Identification Presentation shall be portable.V. Each company or operator should provide the routing arrangements needed
to port the mobile number.VI. Once you port the your number you can not port it to another operator within
90 days.VII. Process should follow the rules and regulations announced by the TRAI i.e.
Telecom Regulatory Agency of India.

Components of MNP
Central Reference Database (CRDB):- The CRDB is the database where the ported numbers are stored and take
care of the network update and administration message flow between the various operators.
CRDB can be active or passive: Active: Store, distribute and validate message
Passive: Store only.

Advantage:- No centralized database needed Internal NPDB can be stand alone and contains only the ported number from the donor
network. Good solutions for short term or if a small percentage of subscribers chooses to do number
portability. Disadvantage:- Completely relies on donor network during call setup. Requires setting up two call segments.

Advantages:- Centralized number portability database not needed. Internal NPDB can be stand alone and contains only ported number from
donor network.
Disadvantages:- Involves the donor network during call set up. Circuits are reserved temporarily during call setup.

Advantages: Centralized number portability database used for call routing decisions. Does not involve the donor network. Efficient in usage of switch, port and circuits. Good long term solution, especially when most subscribers choose number
portability. Disadvantages: Relatively high portability set up cost. High traffic to NPDB from originating switches.

Advantages: This solution utilizes a standard interfaces and signaling functions in order
to minimize the need for further system development. This solution supports speech, fax, data, short-message service, call-back
when subscriber is no longer busy and optimally routed calls.
Disadvantages: This solution is very specific for GSM. This solution is not applicable to other mobile network technology such as
CDMA.

Advantages: Elimination of reliance on the donor Service provider, thereby providing
the ability to maintain portability when Service providers fail and exit the market.
Optimized routing, and the resulting elimination of the costs of additional conveyance, will serve as an inducement to win end users, fostering competition.
Disadvantages: Since this solution is newly introduced in some countries, therefore this
may be considered as disadvantages, because of unawareness of solution.

Future Scope and Conclusion• The success of the implementation of MNP would depend on a number of
factors including
Porting Time: Porting Fees: Better Price Deals:
• MNP allows effective utilization of numbering resources, as one customer is bound to his mobile number for longer time.
• So, if above points are taken into consideration there is better future for this technology in India.
