Number Portability
Number Portability (NP) enables a subscribers to
• Switch between Services.
• Locations
• O erators..
While retaining the original Telephone number without compromising on quality, reliability andoperational conveniences.
3 Types of Number Portability (NP)
• Operator Portability.
– FNP-Fixed Number Portability
MTNL2
– MNP- Mobile Number portability.
– INP- No Geographic IN Number Portability
• Location Portability.
• Service Portability.

Mobile Number Portability
Mobile Number Portability (MNP) allows mobile subscribers toretain their existing mobile phone number (MS-ISDN) when theyswitch from one access service provider to another.
Subscribers can move or ‘port’ the phone numbers betweenservice providers of same nature- i,e. Mobile to Mobile.

Mobile Number Portability
Mobile Number Portability (MNP) is inbuilt in GSM MobileStandard.
Mobile Instrument-
IMEI( International Mobile Equipment Identity)
SIM-IMSI(International Mobile Subscriber Identity)

MS-ISDN( Mobile Number)
MS-ISDN Numbers are not used for routing in GSM network. Theseare used for routing only in GSMPSTN Network

MNP-Implementation
Mobile Number Portability (MNP) can be implemented inMobile network as IMSI identifies the MS(Mobile Station) and stored in SIM.
IMSIMS-ISDN correspondence is stored in HLR.
MSISDN is used in call routing in PLMN/ISDN area.

MNP-Concepts
Issues to be resolved for Mobile Number Portability(MNP) between Service Providers.
• Administration-Process for Porting Numbers& Management of Ported Number.
– Order Processing.
– Port Provisioning
– Port Notification & Network Synchronisation
• Call Routing- Process for routing of calls todialled number between Service Providers..

MNP in India
MNP was under discussion since 2004-2005 when MNPhas become trend in all western Countries.
The Tele-density and Growth (50-55%) of MobileConnections at July 2005 was right time to implementMNP.

MNP in India
TRAI has issued consultation paper in July 2005 andissued recommendations in March 2006.
TRAI recommended to implement MNP in India inPhased Manner-
• First in Metro Cities.
• Category ‘A’ Service Area.
• Category ‘B’ and ‘C’ Service Area.
Tentative Date for MNP implementation recommendedwas 1st April 2007.
TRAI has recommended settin u of Mobile Number
MTNL17
Portability Clearing House Administrator (MCHA) whowill maintain the
• Number PortabilityDatabase(NPDB)
• Query Response Database(QRDB).
TRAI has Suggested two MCHA• Zone 1- West & North India.
• Zone 2- East & South India.
MNP in India
TRAI has recommended separate license for MNP
Operator, with revenue coming from the port transaction
fees from Universal Access, CMTS, ILD, NLD Operators.
Now DOT has issued LOI to MNP Licensee.
• Zone-1- M/s Syniverse Technologies (India) Pvt. Ltd.
• Zone-2 -M/s MNP Interconnection Telecom Solutions
India Pvt. Ltd.
As per License, MNP to start within 6 months of LOIIssue.- i.e. Aug’09 .Testing Time is app 3 months. i.e.June’09. All Infrastructure in MTNL to be ready byJune’09.
