In this solution, MME translates the security context of EPC into the legacy PS format, translates the R8 QoS profile into R99/R97 QoS profile and just acts as a SGSN to interconnect with legacy PS core. The gateway also supports GGSN function at the same time and can act as the common anchoring point for the multi-mode UE wherever the UE is in EPC or in the legacy PS core.

Generally, these two logic functions are combined into
one physical node.
The EPC core is interconnected with legacy 2G/3G PS core by S3/S4 interface. In this solution, the existing SGSN should be upgraded to become S4 SGSN and the existing GGSN should be upgraded to become SAE-GW. The serving gateway becomes the common anchoring point between LTE and 2G/3G. In this case, the legacy PS core can enjoy some enhancement of R8, such as the label QoS profile, the idle signaling reduction and so on.
