E.164 Number Mapping

Mobile Number Portability 4G & 5G

Telephone Number Mapping (E1.64 Mapping) connects users from Circuit Switched Networks (CCS) to IP/IMS Core. While not the only driver, a key factor for transitioning to IMS-Core is to free up frequencies for 5G. ENUM now includes Bootstrapping Server Function (BSF) and authentication proxy capabilities for seamless integration. Transforming core number mapping into a scalable VNF/CNF function, such as Enea’s ENUM solution, enhances network connectivity and reduces costs.

Number Portability – Customise & Connect

Connect users with customized number mapping.

  • SIP ENUM for mapping IMS-Core and CS
  • Enable VOLTE for VoWi-FI
  • Linearly scale as Virtual Network Function or Container Function (VNF/CNF) multi-site up to 500M entries
  • ENUM supports DNS & MAP Protocol – IP & SS7 Interworking

DNS: Connect Networks

Save Cost & Harmonize name resolution for IMS network elements.

Number DNS (iDNS) provides the fundamental lookup function for E.164 mapping between SGSN and GGSN, supporting both local and roaming connections.

ENUM empowers networks with:

  • Quick core network node detection and selection.
  • Tailored zone views based on clients’ source IP address
  • Intelligently delivery of only active node addresses, boosting network efficiency
Enea ENUM supports DNS resource record types:

A/AAAA, NAPTR, S-NAPTR, CNAME, MX, NS, TXT, PTR)
