WHAT IS MOBILE NUMBER PORTABLITY
MNP
3
Types of MNP

• SERVICE OPERATOR PORTABILITY
• LOCATION PORTABILITY
• SERVICE PORTABILITY

4
SERVICE OPERATOR PORTABILITY

• retain the same geographic number when changing
  from one operator or service provider to another.
• Currently being used in INDIA

5
LOCATION PORTABILITY

• 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

6
SERVICE PORTABILITY

• Retain the same geographic number when changing
  from one service to another
• From basic telephony to ISDN(Integrated Service
  Digital Network)

TECHNICAL ASPECT

• NUMBER POOLING
• NUMBER PORTABILITY DATABASE
• ROUTING MECHANISM

9
NUMBER POOLING

• Due 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

10
NUMBER PORTABILITY DATABASE

• The 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

11
ROUTING MECHANISM
12
All Call Query

• 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.

13
Onward Routing

• 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.

14
Call Dropback

• 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

15
Query on release

• 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

CHALLENGES

• Customers 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.

20
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

21

• ADVANTAGES

• DIS ADVANTAGES

• Change in location having same number
• cannot switch again for the next 90 days.
• Change in hand set when change in platform

• Can retain existing mobile number.
• Just for a small fee of    19/-
• You can switch from GSM to CDMA and vice versa

22
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

23
CONCLUSION

• Number 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
