Definition Of M.N.P

Mobile Number Portability (MNP) is a service offered by all mobile service providers that allows users to switch over to another service provider of their choice while retaining their existing mobile number, increasing the level of competition between service providers , and rewarding its users with the best customer service, network coverage, and service quality.

History of M.N.P

Mobile number portability launched in India in Haryana on 25 November 2010.

It was finally launched all over India on 20th January 2011.

SERVICE OPERATOR PORTABILITY

Service provider portability or Local Number Portability is the ability of end users to retain existing directory numbers at the same location as they change from one service provider to another.

LOCATION PORTABILITY

Location portability is the ability of users of telecommunications services to retain existing directory numbers without impairment of quality, reliability, or convenience when moving from one physical location to another.

SERVICE PORTABILITY

Service portability is the ability of users of telecommunications services to retain existing directory numbers without impairment of quality, reliability, or convenience when switching from one service to another service provided by the same carrier.

TECHNICAL PROCESS OF M.N.P

MNP Terminologies related to network

Originating Network : Network of the calling party

Donor Network : Previous subscription of Called party

Recipient Network : Present subscription of Called party

NPDB : Number Portability Data Base

ARCHITECTURE OF M.N.P

The various architecture elements which are essential for MNP are described in the following slides

Service Order Administration (SOA)

Service order administration provides the functionality to interface to carriers’ order and provisioning systems in order to update the NPAC for access by all other carriers.

The SOA’s primary functions include subscription audit request/management; data administration; data transfer to the NPAC; report generation; bulk-file upload; subscription tracking; legacy order entry interface; and logging.

Depending on an individual service provider’s

requirements, the SOA may interface with multiple NPACs to allow for nationwide number portability.

The carrier-to-SOA connection may be custom-designed to interface with existing carrier order entry systems.

Number Portability Administration Center (NPAC) The NPAC is designed to receive information from both the

incumbent and new service providers, validate the information received, and download the new routing information when an activate message is received indicating that the customer has been physically connected to the new service provider’s network

. Each ported number is a subscription version within NPAC that contains

the new service provider’s ID, the location routing number (LRN) associated with the new switch, and routing data associated with additional services, the customer may request.

The NPAC provides management, administration, oversight, and integration of NPAC operations, hardware and software development, and all maintenance related functions.

It is responsible for meeting performance standards established by the

industry and providing user and technical support services and training for industry participants on an ongoing basis.

Local Service Management System (LSMS) The local service management system is a fault-tolerant

hardware and software platform that contains the database of information required to enable routing and call completion to ported telephone numbers.

The primary functions of the LSMS are subscription

management, network data management, service provider data management, error processing and notification, transaction event logging and reporting, transmission of activation/deactivation events to the network elements, and audits.

The LSMS interface with the NPAC provides real-time activation/deactivation information upon download from the NPAC and can send responses to the NPAC once a message or subscription version is processed.

OTHER ELEMENTS OF THE ARCHITECTURE

Service Control Point Management System: The service control point management system provides interface services between the LSMS and the SCP. The SCP MS may or may not be physically integrated with the SCP.

Number Portability Database (NPDB): The number portability database contains the routing information necessary to support number portability. The NPDB provides the LNP association between the called party and the carrier LRN, identifying the switch to which the call should be routed. The NPDB stores all ported numbers within the ported domain.

Contd...

Signal Transfer Point (STP): The signal transfer point receives the LRN query from the SSP/MSC and routes the query to the appropriate LNP SCP

Mobile Switch Centre (MSC): The exchange carrier owns and operates the mobile switch centre. Service switching points must be able to generate an LNP query to the SCP (via the STP network) when a call is placed to a telephone number in a ported domain.

Whenever a call is originated, the Originating n/w will query its NPDB (Number Portability database)

ACQ (All Call Query Method) is called as direct routing, The Donor Network will not be part of the entire call flow. This method is the presently used in India

LRN + B-MSISDNBased on the prefixed LRN the Originating n/w will route the call to the recipient n/w without involving the Donor network.

NPDB will acknowledge the query by adding a prefix LRN (Location Routing Number) to the called number.

ADVANTAGES OF M.N.P

ADVANTAGES OF MNP IN INDIA TO USERS:• Will not have to change the number.• Save money by having the best plan you like.

ADVANTAGES OF MNP IN INDIA TO OPERATORS:• Savings in expenses for reserving a number-series.• Healthy competition and an opportunity to explore more

services/features.

ADVANTAGES OF MNP IN INDIA TO GOVERNMENT:• More competition means more revenue.• More investment in market.

DISADVANTAGES OF M.N.P DISADVANTAGES OF MNP IN INDIA TO USERS:• Process takes 6-7 days.• Users lose their old prepaid balance after porting.

DISADVANTAGES OF MNP IN INDIA TO OPERATORS:• Technology change.• More competition with other companies.

DISADVANTAGES OF MNP IN INDIA TO GOVERNMENT:• More competition to BSNL.• Loss due to dropdown in number of mobile numbers.• No More number series reservations.

FUTURE ASPECTS…

The future seems to be bright for this technology in India. The reason for being so is that currently, according to the government statistics, about 68% of all mobile customers change their mobile phone number at least once in a year.

Indian users would have a MNP like location portabily and Service portability in future.

When Mobile Number Portability in India is complete, the number will drop significantly and only those people will change the numbers who really want to disconnect the mobile service or want to become anonymous again.

CONCLUSION..

The MNP process is relatively new to India but holds lots of scope. With the revolution of mobile telephony sector in India, the subscriber base has grown by leaps and bounds over the past decade.

It can also lead to lots of errors like customer

dissatisfaction, misalignment between the old and new service operator, loss of revenue and negative publicity. Hence proper infrastructure needs to be in place for it starts in India.
