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.
