LTE Control Plane on Intel® Architecture
The Long Term Evolution (LTE) control plane is responsible for control operations such as network attaches, security control, authentication, setting up of bearers, and mobility management. It corresponds to the information flow and signaling between User Equipment (UE), Evolved-UMTS Terrestrial Radio Access Network (E-UTRAN) and Evolved Packet Core (EPC), which includes all the Radio Resource Control (RRC), EUTRAN signaling and Non-Access-Stratum (NAS) signaling. In other words, the LTE control plane is a string of sequential operations that are very compute centric. Intel® Architecture Processors are competitive in terms of performance/watt, and are an excellent choice for control plane applications.
This paper provides an overview of the LTE control plane architecture and the nature of the computing power required to optimize control plane system performance. To help select an Intel® Architecture Processor that provides the needed power/performance, you can use the EEMBC CoreMark* benchmarking tool. Examples of how to do this are provided, along with current platform options from Intel.
