NETWORK CONNECTION EXCEPTION PROCESSING METHOD, ELECTRONIC DEVICE, AND STORAGE MEDIUM

Embodiments of the present application relate to the field of communications, and disclose a network connection exception processing method, an electronic device, and a storage medium. In the present application, the network connection exception processing method is applied to a distributed unit (DU) of a dual-mode base station. The dual-mode base station is simultaneously used in a standalone (SA) network and a non-standalone (NSA) network, and comprises a DU and a centralized unit (CU) that are in communication connection; the CU is configured to separately establish a connection to a first core network and a second core network, and data transmission between an SA user end and the first core network and data transmission between an NSA user end and the second core network are implemented by means of the DU. The method comprises: upon reception of first core network connection exception information sent by the CU, sending a notification of a connection exception between each subordinate cell and the first c
