1. SERVICE OPERATOR PORTABILITY

2. LOCATION PORTABILITY

3. SERVICE PORTABILITY

SERVICE OPERATOR PORTABILITYretain the same geographic number when changing

from one operator or service provider to another.

Currently being used in INDIA

Customer to retain the same geographic number when moving from one location to another

Location portability would allow customers to take their number when they move to a geographic location outside of the original rate center

LOCATION PORTABILITY

SERVICE PORTABILITY

Retain the same geographic number when changing from one service to another

From basic telephony to ISDN(Integrated Service Digital Network)

• NUMBER POOLING

• NUMBER PORTABILITY DATABASE

• ROUTING MECHANISM

NUMBER POOLINGDue to shortages of numbering resources FCC had approved a National

Number Pooling plan for network resource optimization

The concept of pooling is based on the fact that whole blocks of telephone numbers, held by some service providers, are not assigned or in service. Pooling allows these currently unassigned blocks of numbers to be reassigned to other service providers in need of numbers, as they request and show need.

As that supply depletes, service providers will request additional numbering resources from the industry inventory maintained by the Pooling Administrator

NUMBER PORTABILITY DATABASEThe number portability database (NPDB) keeps track of the ported numbers

and their respective service providers

The NPDB can be either centralized or distributed

In the centralized model, there exists a single reference database

In the distributed model there exist multiple databases, each containing subsets of the total data, e.g. only the numbers assigned to particular service provider

• The Originating Network receives a Msg/call from the caller and send a query to a centrally administered Number Portability Database (NPDB)

• The NPDB returns the routing number associated with the dialed directory number. • The Originating Network uses the routing number to route the call to the new serving network.

• The Originating Network receives a call from the caller and routes the call to the donor network

• The donor network detects that the dialed directory number has been ported out of the donor switch and checks with an internal network-specific NPDB

• The internal NPDB returns the routing number associated with the dialed directory number

• The donor network uses the routing number to route the call to the new serving network.

• Receive call to the donor network. 

• The donor network detects that the number has been ported out of the donor switch and checks with an internal network-specific NPDB

• NPDB returns the routing number

• The donor network releases the call by providing the routing number

• The Originating Network uses the routing number to route the call to the new serving network

• A call from the caller and routes the call to the donor network.

• The donor network releases the call and indicates that the dialed directory number has been ported out of that switch

• The Originating Network sends a query to its copy of the centrally administered NPDB

• The Originating Network uses the routing number to route the call to the new serving network

CHALLENGESCustomer’s value added services will

be lost  What for fixed lines? Local number

portability includes some thing as Standard Transfer, Like-for-Like Transfer. These are really challenging to setup and bill accordingly.

BENEFITS OF MOBILE NUMBER PORTABILITY

MNP  gives best benefit to the customer, as they do not have to change their number, eliminating a great headache of communicating the new number to all his/her important contacts

MNP will keep all the mobile network providers on an alert

Network provider will really treat the customer as a king. You will get lightning response and great customer service from your existing mobile network providers

ADVANTAGES DIS ADVANTAGES

Can retain existing mobile number.

Just for a small fee of    19/-

You can switch from GSM to CDMA and vice versa

Change in location having same number

cannot switch again for the next 90 days.

Change in hand set when change in platform

FUTURE IMPLEMENTATION switch from one geographic location to other i.e. having one

number across the country. Example if your number is registered in Karnataka you can switch to a service provider in Gujarat

  Not loosing balance on prepaid cards.  Changing from CDMA-to-GSM or vice-versa,without

change in handset  If the customer has extra services, like caller tune, GPRS,

voice mail and others alike, then these services will not be lost

CONCLUSIONNumber portability removes important barrier to increased competition in

the telecommunications sector.

As such, it brings challenges and opportunities for old and new telecommunications providers

To be successful in the competitive telecommunications environment, carriers have to carefully analyze their network and administrative infrastructures, select the best number portability solution for their needs and exploit the benefits of increased customer choice that NP provides
