A method for managing ciphering configurations for LTE WLAN Aggregation includes a source evolved Node B ciphering configuration which is implemented at a mobile device and at a source eNB, for communicating data between the mobile device and the source eNB via a WLAN node. A WLAN ciphering configuration is implemented at the mobile device and at the WLAN node, for communicating data between the mobile device and the source eNB via the WLAN node. In response to determining that the WLAN ciphering configuration has been implemented, a message is transmitted indicating that the WLAN ciphering configuration has been implemented and at least one action is performed in response to the message.
