Session control synchronization method and device and medium

The invention discloses a session control synchronization method, a session control synchronization device and a medium, which are suitable for the technical field of computers. Comprising the following steps: acquiring a plurality of sessions and corresponding data block structural bodies; performing corresponding locking processing on the information of the plurality of sessions in the data block structural body to create respective lock files; and when the session synchronization is completed, carrying out unlocking processing on the lock file corresponding to the session after the synchronization is completed. According to the invention, when locking processing is carried out in the session synchronization process, respective corresponding lock files are created for a plurality of sessions, different sessions are synchronized with different lock files, respective session synchronization processes are not affected, even if the lock file of the current session is not released in time, locking processing of
