Gateways

• Data management and policy server apps • Virtualization starts with front-ends • HSS follows IMS, TAS for VoLTE • Centralization on private cloud possible

• Rich signaling and control SW applications • First step demonstrated with IMS, TAS • MME virtualization path followed by SGSN • Centralization on private cloud possible with

migration to all-IP interfaces

• Varying degrees of HW dependency • First step with EPC gateway virtualization

• Additional flexibility • User plane performance tradeoff on
