PCRFAF / P-CSCF
Used open source Diameter stack (Base Protocol Stack) for Encoding, decoding, session handling , transport and timers Built Parser to handle messages independent of any interface ; Does parsing of application specific message format to Stack format and vice versa. Created a common framework for initialization and configuration Developed APIs to transfer data between application and stack Built PCEF application specific functions with Gx Interfaces QoS and charging enforcement, Service data flow management, PCC rule managementC O N F I G L O G G E R

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)
