An exception processing method, device and storage medium
By working together between the first and fourth network elements and using pre-defined messages to synchronize session context information, the problem of service unavailability caused by intermediate network element failures was solved. This enabled service interruption during network element failures and lossless switching after recovery, ensuring the continuity and reliability of user services.

AI Technical Summary
Technical Problem
In the presence of intermediate network elements, when a network element fails, existing technologies render services unavailable, and there is no corresponding activation mechanism after the network element recovers.
Method used
Through the collaborative work between the first and fourth network elements, the user session context information is synchronized by using a pre-defined message to carry the cause value and network element ID, thereby enabling the seamless switching of services during migration to the backup network element and after normal operation.
Benefits of technology
It achieves uninterrupted service during network element failures and seamless switching after fault recovery, ensuring the continuity and reliability of user services.

Abstract
The application discloses an abnormality processing method, device and storage medium, comprising the following steps: a first network element receiving a third network element which is a backup of a second network element after the second network element fails, the first network element being an intermediate network element; learning that the second network element is abnormal; informing a fourth network element that the second network element is abnormal through a predetermined message; migrating a service to the third network element by the first network element; and / or receiving the third network element which is a backup of the second network element after the second network element fails; detecting that the second network element is normal, and / or receiving a message that the second network element is normal which is sent by the second network element; informing the fourth network element that the second network element is normal through a predetermined message; and migrating the service to the second network element. The application can solve the problem of service interruption of a user when a main network element fails in the presence of an intermediate network element.
