Challenges on Evolution Phase Phase-1 How to introduce EPC for LTE Phase-2 EPC deployed for broadband data service
Challenges Migration from legacy CN or built new EPC? Key technology deployed at initial stage Data service availability and continuity out of LTE Cut the operation cost of multiple networks How to introduce voice service for LTE user
Phase-3 Full service operation in LTE
Guarantee QoS control and service control for full services operation Legacy network migration or swap-out.

Lower CAPEX at initial stage
Higher OPEX, because of GSN ‘s lower capacity and integration

CSFB- UE speech fall back to 2/3G, No VoIP on LTE
Fall back to CS for MT/MO ,make full use of existing CS network.
VMSC should be upgraded to support SGs I/F (similar to Gs I/F) to perform functions like combined LAU, page and SMS etc.
Simple structure, IMS is not necessary.
SRVCC- LTE VoIP with IMS control
Based on the control of SCC AS and SRVCC enhanced MSC, LTE voice can handover to CS network.
IMS deployment is required for the control of multi-media service
Separated SRVCC enhanced MSC can be deployed to provide Sv and SIP I/Fs, avoiding upgrade of all MSC.

Network deployment cost
1) Upgrade MSCs overlapped by LTE coverage to support SGs; 2) Upgrade MME to support SGs
1) IMS system deployed for UTRAN/ GERAN reuses the session transfer function defined for IMS; 2) Upgrade MME to support Sv; 3) Upgrade MSC to support Sv

CS UE
UE need to support LTE access. User feeling is same as CS domain short message. MME and MSCS support SGs association, SMS message transfer on SGs. No special requirement to other nodes MSCS for SMS over SGs can be newly deployed to avoid existing MSC update.
UE need to support IMS instant message service and user can send multiple content as text, picture, flash or other document. Normally IMS instant message is integrated with buddy list and their presence state to promote good user feeling. A new node named IP-SM-GW is need to deployed for SMS interworking with CS domain. IP-SM-GW supports message domain selection, message format transformation and large message fragment. No special requirement to other network node.
