Claim 3:
4. The method according to claim 3, wherein the determining, by the terminal, that the user plane data carried on the DRB fails the integrity check comprises:
in case that at least one of data packets carried on the DRB fails the integrity check, determining, by the terminal, that the user plane data carried on the DRB fails the integrity check; or
in case that a ratio of the number of data packets carried on the DRB that fail the integrity check to the number of received data packets carried on the DRB exceeds a preset threshold, determining, by the terminal, that the user plane data carried on the DRB fails the integrity check; or
in case that the number of data packets carried on the DRB that fail the integrity check exceeds a preset number, determining, by the terminal, that the user plane data carried on the DRB fails the integrity check; or
in case that the number of data packets carried on the DRB that fail the integrity check exceeds a preset number in a preset duration, determining, by the terminal, that the user plane data carried on the DRB fails the integrity check; or
in case that the number of consecutive data packets carried on the DRB that fail the integrity check exceeds a preset number, determining, by the terminal, that the user plane data carried on the DRB fails the integrity check.
