Number Portability (NP) has already been implemented in over 50 countries. That means that more than
250 million telephone numbers have been ported
And over 2.3 billion numbers worldwide now have the potential to be ported. With India implementing NP this year and China and Russia planning to launch NP by the end of 2012, these numbers are set to grow by 50%.
But
NP creates serious technical challenges for the industry
While NP benefits subscribers, it presents Service Providers (SPs) with significant complexity and additional costs. Carriers and Hubs do not always have access to in-country NP data, originators do not always know which carrier/hub to choose, and traffic and revenue may be lost where robust number portability correction arrangements are not in place.
To mitigate this challenge, carriers can acquire NP data from a variety of sources and manage that data on an ongoing basis. This requires tailored content interfaces, disparate technologies and diverse business arrangements that can be prohibitively expensive.
GSMA PathFinder Number Portability Discovery service provides critical Number Plan and NP information enabling identification of the true destination network on a worldwide basis. Customers can query this high performance in real time as part of their routing decision process.
PathFinder Number Portability Discovery is a managed service. Data is continuously refreshed, scrubbed and stored by a dedicated team to provide a high quality, low latency source of number portability data. So the service requires no numbering data to be added, provisioned or maintained by customers. In addition, new sources of data are continuously added as required, or when new countries come on line.
How it Works:
PathFinder is a one-stop shop for global number portability resolution, reaching 1.8 billion, 81% of the worldâs portable numbers (fixed and mobile), the most comprehensive onboard data in the industry. Click here to request coverage details. PathFinder uploads NP data into geographically distributed query nodes to provide a high quality, low latency query service. Onboard data allows PathFinder to deliver the fast response times needed for real time voice and messaging routing decisions. Additional countries not yet integrated are accessed remotely.
Users can query a legacy number in PathFinder and receive either the E212 MCC, MNC or a GSPID identifying the destination operator. In some countries, information may also be available in the form of an alternate GSPID for virtual operators such as MVNOs and âwhite labelâ voice services. The MCC MNC codes are uniquely allocated to each mobile operator by the ITU and therefore accurately signal the destination network. The GSPID and AltGSPID are five digit numbers allocated to networks which do not have a MCC MNC code. This allows PathFinder to signal fixed operator destinations with equal accuracy
Examples of Use Cases
Key Benefits
Worldwide Coverage:
The NP Discovery service has extensive reach to national NP data with a combination of onboard data and external access covering almost two billion portability susceptable telephone numbers and over 5 billion TNS from 226 countries of number block data.
Simplicity:
Providing a âone-stop-shopâ access to worldwide NP data, PathFinder NP Discovery Service greatly alleviates System Integration complexity for SPs by allowing them to have a singular standardised data interface, technology and business arrangement for accessing NP data.
Rapid Integration:
Number Portability adoption is spreading across the globe. The PathFinder NP Discovery service leverages powerful data integration technology to rapidly assimilate additional NP data for new corridors as demand dictates.
Number Plan Query Service
PathFinder covers 100% of the worldâs number block assignments, over 5 billion TNs fixed and mobile, across 226 countries.
PathFinder Number Plan Query Service complements the Number Portability Discovery Service. It enables users to look up network ownership of non-ported numbers based on international authoritative number block assignments when NP data is not available or relevant.
Summary
By signing up to PathFinderâs NPD service, users will be able to save money on interconnect using least cost routing techniques based on accurate number ownership data. Users will also be ready to migrate to more sophisticated Carrier ENUM data for NGN interconnect.
