Interworking between existing 2G/3G networks and 4G/LTE networks is becoming a high priority. LTE roaming enablement across multi-vendor and multi-peering environment. Service providers are keen to maximize mobile reach by enabling services between LTE and existing networks and to ensure seamless service continuity for their subscribers. For (smaller) operators and MVNOs, acquiring LTE technology is often a big hurdle.
BroadForward’s BFX Interface Gateway offers a viable solution. It enables the existing 3G network to interwork with LTE against much lower costs and without the requirement for upgrading network equipment, thus preventing the need for a long and risky project. With the on-board MAP-Diameter Interworking function, BFX provides operators and vendors with an essential capability for LTE roaming.

Standard MAP-Diameter IWF implementations only work for recent HLR releases (3GPP release 8 and higher). This blocks the opportunity to offer 4G services for hundreds of operators and MVNOs worldwide. BroadForward developed a special 3G-LTE interworking function that connects existing, older generation HLRs (pre-release 8) to 4G/LTE networks. With this special function, BFX supports the creation of KASME security vector information, required for connectivity with a pre-release 8 HLR. Now (smaller) operators and MVNOs are empowered to break through the typical vendor lock-in situation associated with upgrading to newer generations of network technology.
