Lte Migration Services

MigrationUMTS-to-Lte

Rationale A phased migration to Lte in a predominantly UMTS network is approach to increase cell capacity or throughput

EV-DO-to-Lte

Latency in PMIP based EVDO-Lte session transfer would be unacceptable. EVDO Migration can be facilitated with pre-registration at target network

Facilitates Lte deployments without IMS deployment

CS Fall back option for Lte Uses the existing 2G/3G networks for Voice calls and other services. Voice and SMS Option to migrate to native Lte VoIP services at a future date.

2G - Lte interworking with IMS and VCC for Voice Services

Voice Call Continuity server (VCC) can be used for 2G (GERAN/CDMA 1X)
