Abstract
In general, the current subject matter relates to handling core network connection failure. In some implementations, an F1 interface can be set up between a centralized unit (CU) of a base station and a distributed unit (DU) of the base station. Setting up the F1 interface can include transmitting core connectivity status information from the CU to the DU, and the core connectivity status information can indicate to the DU whether or not the CU has connectivity with a core network.
