Legacy SS7 Networks route traffic by translating Mobile telephone numbers into infrastructure point codes which define the destination. Typically, the INAP protocol is used for querying number portability information sources such as a Centralized Database (CDB) containing ported numbers.
A central Number Portability gateway supporting both INAP and ENUM, as well as various other Network and IT interfaces, provides an essential capability to service providers to cost-effectively connect legacy and IP domains, overcome interoperability issues and establish convergence across Mobile, Fixed and OTT services.
Number Portability Gateway offers on-board support for: INAP (supporting: Q.1218, ETS 300 374-1, EN 301 140-1) and ENUM (compliant with RFCs 6116 (ENUM), 3403 (NAPTR) and 4694 (NP tel URI)), SOAP, MAP, Diameter and various other protocols.
Real-time Number Portability queries/dips, across local and external data providers
Capability to resolve mobile number via local database, and in case this entry is not present the NP gateway could query external data provider or IT infrastructure to resolve the number.
Local database with unlimited capacity
Local storage and caching of Number Portability information, reducing the number of external queries/cost
Multi-protocol support, including ENUM, INAP, SOAP, MAP, Diameter
Having more protocols on-board in a single solution gives the operator the advantage to extend the usage of the Number Portability to more then the standard functionality.
Local and unlimited Number Portability Database
Future proof Number Portability system supporting VoLTE with build-in ENUM server
