  • flexran-eol
    End-of-life (EOL) of FlexRAN
    
    FlexRAN has been OpenAirInterface's (4G) RAN Controller before there was
    O-RAN or an E2 interface. It has been initially merged with tag
    2016.w49. Multiple iterations added functionality to control the MAC; to
    dynamically add multiple MMEs; to control handover; to retrieve
    statistics of MAC, RLC, PDCP, GTP, RRC, S1AP; to control slicing
    operation; and other functionality, to name a few.
    
    Development has stalled, and another controller named FlexRIC, based on
    the E2 interface, has been implemented. The latter's E2 Agent will be
    added to OAI soon. The now deprecated FlexRAN is therefore removed in
    preparation to merge FlexRIC's E2 Agent in the future.
