Abstract

Disclosed in an embodiment of the present invention are a new security key activation method access network node user equipment and UL boosting system when a UMTS and LTE aggregation system is switched to a UMTS single system. The method comprises the following steps: receiving a first downlink key activation time parameter sent by an RNC and synchronizing the self downlink key activation time with the time represented by the first downlink key activation time parameter according to the first downlink key activation time parameter; activating a new security key according to the first downlink key activation time parameter; and/or obtaining a self second uplink key activation time parameter and transmitting the second uplink key activation time parameter to the RNC so as to enable the RNC to synchronize the self uplink key activation time with the time represented by the second uplink key activation time parameter; and activating the new security key according to the second uplink key activation time parameter.
