4G - Long Term Evolution/Evolved Packet Core (LTE/EPC)

3GPP System Architecture Evolution (SAE) philosophy

eEnhancement of Packet Switched technology to cope with rapid growth in IP traffic.
- higher data rates.
- lower latency.
- packet optimised system.
Through.
- fully IP network.
  - In addition to IMS services available in the current system, equivalent CS Services may be provided by IMS core since CS domain is not supported in LTE.
- simplified network architecture.
  - Reduced number of nodes in the evolved packet core may be achieved compared to current architecture to provide connectivity to IMS.
- distributed control.
  - Flexible accommodation and deployment of existing and new access technologies with mobility by a common IP-based network.
