* this function is used by both CU-CP and CU-UP * it behaves differently depending on the type of E1 instance: CU-CP: inform RRC of E1 connection loss with CU-UP CU-UP: trigger a new SCTP association request by sending an ITTI to the CU-UP task * after receiving the E1AP register request, the CU-UP will send a new association request to SCTP until new E1 connection is achieved by sending a TIMER_HAS_EXPIRED message to the CU-UP task. The function e1apHandleTimer() is basically triggering a new E1 association request until new E1 connection is achieved * print SCTP association state in e1ap.c whenever needed Related to #878
