Wi-Fi Offload

Spectrum shortage is driving MNOs to leverage Wi-Fi technology to offload data from the core network.

This creates a corresponding need for an alternative authentication mechanism for subscribers who use SIM-based dongles in their PCs to access network data services via wireless LAN.

A MNO who uses a Home Location Register (HLR) as the basis for SIM authentication requires a solution that can convert the AAA Diameter queries to SS7, launch a MAP query to the HLR, and return the result in Diameter.

Mitel's Diameter SS7 Gateway provides authentication access for AAA by interworking the Wx and SWx based diameter authentication queries/responses to MAP requests/responses.
