Overview of Mobile Number Portability
- Randeep Kumar, SDE
MNP Definition
"Mobile Number Portability" means the facility which allows a subscriber of a mobile telephone service to retain his mobile telephone number when he moves –
from one mobile telephone service provider to another, irrespective of the mobile technology
or
from one mobile technology to another of the same mobile telephone service provider, within such limits as may be permitted by the licensor”
MNP Definition
Presently, Number portability is permitted only within LSA and not across LSAs, in India.
That means subscriber can change
• Operator say Airtel to Idea, or
•Technology – GSM to CDMA or vice versa, or
•both say Reliance CDMA to Vodafone GSM
While retaining his mobile number
MNP Aspects
There are basically 3 aspects to be taken care of by operators while implementing MNP :-
i. Commercial – Provisioning of Port in and De provisioning of Port Out subscribers.
ii. Call Routing in MNP Scenario
iii.Charging / Billing of subscribers for their usage.
Other aspects like strategies for preventing port out and promoting port IN customers are vital but not not in the scope of this session.
TERMINOLOGY
"Donor Operator" “-
means a operator from whose network the subscriber is porting out.
“Recipient Operator" –
means an Operator who will be providing mobile service to the subscriber after porting

TERMINOLOGY from BSNL
point of view
Foreign Number – Other Operator subscriber not
known to be ported.
( say subscriber of Idea who may or may not have
ported to say Airtel )
TERMINOLOGY from BSNL
point of view
TERMINOLOGY
"Location Routing Number” means the code assigned to every Access Provider for the purpose of implementing Mobile Number Portability;
These are 4 digit codes and have been assigned by DOT.
They have been assigned LSA wise, Operator wise and technology wise
BSNL has been allocated 42 codes in total – 21 for GSM and 21 for CDMA.
