LTE eNodeB

A Industry-leading access network: The eNodeB framework has a robust ecosystem, a flexible architecture for optimized performance, and an extensive interoperability for a accelerated time to market.

An industry leading eNodeB software framework that helps Communication Equipment Providers (CEPs) and Test & Measurement (T&M) equipment providers develop a complete eNodeB solution with significant time-to-market advantage. The software is also available pre-integrated as an OEM-ready reference solution on industry-leading L1 and silicon/hardware platforms. This is a widely deployed and inter-operated framework with over 70 OEMs having chosen Altran's eNodeB framework or reference solution on different SoC platforms.

The software consists of the following protocols stack/modules:

  • User Plane
    • Media Access Control (MAC)
    • Radio Link Control (RLC)
    • Packet Data Convergence Protocol (PDCP)
    • Evolved GPRS Tunneling Protocol-User plane (eGTP-U)
  • Control Plane
    • Radio Resource Control (RRC)
    • S1 Application Protocol (S1AP)
    • X2 Application Protocol (X2AP)
    • Stream Control Transmission Protocol (SCTP)
  • Management Plane
    • TR-069 Client
  • Application Modules
    • Cell and UE Control
    • Radio Resource Management (RRM)
    • Self-Organizing Network (SON)
    • LTE Operation Administration and Management (LTE-OAM)
