The Diameter Solution Suite™ (DSS) can be deployed in the EPC to act as a SLF or DRA or both. The non-3GPP access elements connect to the DSSand all Diameter traffic passes through the DSS. The DSS examines the Diameter messages and performs load balancing and binding across the multiple instances of the HSS and PCRF. This use case describes HSS and PCRF LTE Load Balancing and Binding for Non-3GPP Access.
