Abstract:
The present disclosure relates to a key generation method, a master eNodeB, a secondary eNodeB, and UE. The key generation method includes: determining a key parameter corresponding to a data radio bearer DRB; sending the key parameter to UE corresponding to the DRB, so that the UE generates a user plane key according to the key parameter and a basic key generated by the UE; receiving a basic key generated by a master eNodeB and sent by the master eNodeB; and generating the user plane key according to the key parameter and the basic key generated by the master eNodeB.
