SECURITY PASSWORD CHANGING METHOD, BASE STATION, AND USER EQUIPMENT

摘要

The present invention provides a security key change method, a base station, and user equipment. The method may include: determining, by a master eNodeB MeNB, that a security key change needs to be performed between a first base station and user equipment UE, where the first base station includes at least one of the master eNodeB and a secondary eNodeB; sending, by the master eNodeB, a key change command message to the UE, so that the UE performs, according to the key change command message, the security key change between the UE and the first base station, and determines, according to the key change command message, whether to keep access stratum configuration information between the UE and the master eNodeB or the secondary eNodeB and/or whether to keep data transmission between the UE and the master eNodeB or the secondary eNodeB; and receiving, by the master eNodeB, a key change complete message sent by the UE, so that the first base station determines that the security key change between the UE and the first base station is completed.
