After a prolonged deliberation, the Mobile Number Portability has been tabled on the Indian Telecom space and it is set to liberalize the final frontiers of competition in the Telephony space. Subscribers have been unwillingly tied on to service providers irrespective of deteriorating service standards, thanks to locked in number series per provider. Now MNP is going to change that all for good. This paper explains the underlying MNP technology and its impact to the telephony ecosystem. This paper introduces the concept of number portability, explains its different types and benefits, and the technical, operational, and economic issues that might arise out of its implementation in India. The specific issues such as ensuring tariff transparency, the National Numbering Plan, and regulating porting charges, etc. have been raised and will need careful consideration. This paper discusses service provider number portability (SPNP), as SPNP is the primary form of number portability that promotes competition among the mobile service providers
the world. It might be thought that number portability would have the greatest impact in maturing markets when service demand growth has eased and the market structure has become more rationalized. However, the decision to introduce number portability could be taken well before that. The Netherlands decided to provide mobile number portability (MNP) when mobile penetration was 10%, and Pakistan, with 6.9% cellular penetration, is planning to introduce MNP shortly. This suggests that it is not too early for India to discuss number portability, so that it could be implemented by the time that the market has further expanded in the next few years. In mobile networks, Number Portability involves only the MSISDN number, and not the IMSI. A subscriber who switches to another mobile network operator will be allocated a new IMSI (together with a new SIM card) while retaining his MSISDN. Consequently Number Portability could affect all functionalities and services in mobile networks that are based on the MSISDN number, e.g. • All mobile terminated calls • All mobile originated calls • Short Messages within the Short Message Service (SMS) and MMS • Prepaid services • Any service based on MSISDN The portability information of subscribers resides in a database called NPDB (Number Portability Database). Every operator will have to build a “local portability database” which will download the data from NPDB on a pre defined interval and will be involved in call routing by doing a query to this database for routing information.

The much awaited MNP (Mobile Number Portability) finally launched on 20th Jan 2011 in India, empowering mobile phone consumers to change service provider conveniently. Mobile Number Portability (MNP) allows the mobile subscribers to retain the existing mobile phone number when the subscriber switches from one access service provider (Operator) to another irrespective of mobile technology or from one technology to another of the same or any other access service provider, in a licensed service area. Mobile Number portability (MNP) enables mobile subscribers to change their service providers or their location without having to change their existing phone numbers. If the subscribers are not satisfied with the services of their service provider, they can change their service provider while retaining the existing phone number. A significant technical aspect of implementing number portability is related to...
