This document summarizes a colloquium presentation on mobile number portability (MNP) in India. MNP allows subscribers to change mobile operators while retaining their phone number. The document outlines the types of number portability, the porting process, implementation approaches, routing mechanisms, advantages and disadvantages. Nationwide MNP was introduced in India in 2015, allowing subscribers to port numbers across circles. MNP benefits subscribers through increased competition, value-added services, and free mobility between operators without changing numbers.

3.  Mobile Number Portability (MNP) is an
ability of changing operator (porting)
without changing the number.
 Number portability is a network function
that allows a subscriber to keep a “unique”
telephone number.

6. There are three number portability services :-
• Service portability
• Location portability
• Operator portability
Location
service
operator

7.  Service Portability a subscriber may keep the same
telephone number when changing telecommunication
services.
 Location Portability a subscriber may move from one
location to another without changing his/her telephone
number.
 Operator Portability a subscriber may switch telecom
operators without changing his/her telephone number.

9. Two issues to be considered in implementing
number portability:
 Number Porting Process
 Call Routing Mechanism

10.  The basic requirement of the porting process is that a subscriber
needs to initiate a request to the service provider.
 The request can be initiated to either of the service providers.
 There are two approaches by which the number porting database
can be maintained and implemented.
1. Peer-to-Peer approach.
2. Centralized approach.

11. There are two types of routing :-
 Direct routing
 Indirect routing

13. Originating network connects to the donor network. It detects dialed
number has been ported out of donor switch, then donor network itself
routes the call to the recipient network.

14. The originating network connects to donor network which detects that the
dialed dir.- no. has been ported out from donor switch and check with its LDB
which returns the routing no. and then donor network release the call by
providing the routing no. which is used to route the call to recipient.

15. The originating network first check the status of the dialled number
with the donor network that return a message identifying whether
the no. has been ported out.

16.  Nationwide mobile number portability means, subscribers can
switch to any telecom circle in their country while retaining
the same number.
 The process for full MNP is the same as intra-city mobile
number portability.

17.  Free mobility from one service provider to another, without
changing the mobile number.
 Price competition if the market is competitive.
 Many value-added services may be offered by service
providers to attract customers, either free or at low costs.

18.  You can’t switch from one state to other which
would mean that you can’t have one no. across the
country.
 Once you switch your service provider you can’t
switch again for the next 90 days.
 In case you make a platform shift you will have to
change handsets.

19.  Not loosing balance on prepaid cards.
 Changing from CDMA-to-GSM or vice-versa without change
in handset.
 The success of the implementation of MNP would depend on a
number of factors including :-
1. Porting Time
2. Porting Fees
3. Better Price Deals

20.  Also service provider has to be competitive to attract the
customer.
 This will encourage competition among the service providers,
and in turn will reduce the tariff.
 From subscribers point of view, it should reduces cost, time
and money.
