LTE EPC - The Bedrock of LTE Services
EPC, the Evolved Packet Core, is the all-IP mobile core network for 3GPP LTE. A differentiated EPC forms the bedrock for offering innovative new services, enabling new business models over all-IP LTE mobile networks and running the LTE mobile networks optimally. The LTE EPC in 3GPP Rel 8 brings radical changes in the underlying requirements to build a differentiated LTE mobile core network, making many of the previous 3G platforms insufficient for EPC use. Apart from enabling LTE networks, EPC also allows interworking with non-3GPP access network. WiChorus, a Tellabs Company, industry leading SmartCore 4G platforms are purpose-built to build world-class LTE Evolved Packet Core networks.
The new multi-dimensional requirements of Packet Core networks, fulfilled by the purpose-built SmartCore platforms, are:
Powerful bearer plane performance needed for LTE networks
Highly distributed design to offer massive control plane performance
Fully integrated and tightly coupled L7 capabilities to offer network optimizations and content monetization capabilities
Extensive hierarchical service flow based architecture to offer service enablement and QoE. In LTE, all realtime and non-realtime services, including voice will need to run over IP and extensive service flows based design is needed
Intra Chassis load-balancing for ease of operation
Stateful reliability and redundancy of mobile subscriber state
SmartCore platforms support the following functions for LTE Evoved Packet Core:
LTE EPC is offered on a range or SmartCore platforms, including 9180, 9160 and 9140, to meet the demand of various network size and deployment models.
