2 Core Network Architecture The Interworking architecture must cover: � � � � Mobility Authentication / Security Policy and Charging Fixed / Mobile convergence Current agreed architectures for OFDM-CDMA Interworking � EV-DO (HRPD) � LTE: based on 3GPP Evolved Packet Core (EPC) (agreed in 3GPP and 3GPP2) Common Reference Architecture to Accommodate Performance Requirements and Deployment Models for all Technology Pairings www.cdg.org
2 Inter-system Inter system Functionalities Loose coupling a) “Break Before Make” (MBB) b) “Dual-radio MBB” Tight coupling “Make Before Break” “Network-controlled” Little or no inter-system functionalities UE-centric L3 mobility based on (P)MIP Resources are released in the source system prior to Handover execution Service break is significant Resources in target system are obtained prior to HO execution directly over target radio interface - “seamless mobility” Requires dual radio capability, simultaneous transmit. Requires inter-system functionalities Network-controlled; L3 mobility based on (P)MIP (S101) Ability to configure and report measurements of the target system Inter-system interface for establishing resources in target system prior to HO execution Possibility of data forwarding Suitable for single radio devices, but also applicable to dual radio devices www.cdg.org
