4 Lower TCO
Main Consideration for Evolution
1Migration directly from legacy PS
Legacy GSN should support LTE access
Legacy GSN should provide huge capacity for
LTE
Legacy GSN should support the all IP
networking
Lower CAPEX at initial stage
Higher OPEX, because of GSN ‘s lower capacity
and integration
Upgrading from GSN may impact the legacy
network
2Build new EPC and integrate 2/3G
EPC has the Huge capacity for LTE access
EPC should support All IP networking
EPC should support 2/3G access
Higher CAPEX at initial stage
Lower OPEX, because of huge capacity and
higher integration
Built new EPC has no impact on the legacy

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.

Voice Solution Choices for LTE
ITEM CS Fallback SRVCCNeed IMS No, service is controlled by MSC Yes, service is controlled by IMS
UE1) Support EPS/IMSI Combined procedures 2) CS fallback and SMS procedures.
Need to support SRVCC Capability
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
Terminal deployment cost Software upgrade IMS client Installation
SMS over LTE Solution
SMS over SGs 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.
SMS over IP 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.

Deployment Strategy of Voice Service
； Phase 1: CS FALLBACK is introduced, voice service falls back to legacy CS domain
Phase 2: IMS based VoIP
Phase 3: SRVCC is introduced，single direction LTE to CS Voice continuity is supported
Phase 4: Bi-directional SRVCC handover is provided for Voice continuity
