Abstract
The disclosure provides a method and system for realizing integrity protection. The method includes: a radio connection is reestablished between a base station and a terminal, and the base station notifies the terminal of integrity protection configuration information included in a first Radio Resource Control (RRC) connection reconfiguration signaling after the radio connection is reestablished. With the method in the disclosure, the terminal explicitly acquires the point in time of applying integrity protection, and explicitly knows a data packet to which the integrity protection is applied; furthermore, a Data Radio Bearer (DRB) integrity protection configuration is modified through the first RRC connection reconfiguration signaling after the radio connection is reestablished, thereby it is avoided that the point in time of modifying integrity protection configuration is directly introduced into the RRC signaling, thus reducing the air interface load.
