    Abstract: User equipment includes a receiving module configured to receive first indication information sent by a first base station. The first indication information includes a time period required by the user equipment to request to access a second base station. The user equipment includes a sending module to send the random access scrambling code to the second base station. The user equipment further includes a notification module to notify the first base station that a secondary cell group failure occurs if the user equipment fails to access the second base station within the time period.

    Abstract: A handover method and a base station are provided. The handover method may include: when a UE needs to be handed over, obtaining bearer context information of the UE in a first base station; sending a handover request to a target base station, where the handover request carries the bearer context information; and after receiving a handover response that is returned by the target base station and indicates that the handover is agreed to, sending a handover command to the UE so that the UE is handed over to the target base station. Based on the above technical solutions, the UE handover can be implemented quickly in the case of using multiple carriers and the current service of the UE can be recovered quickly, which can improve communication experience of a user.

    Abstract: A random access method, an evolved Node B (eNB), and a terminal equipment are provided. The method includes: determining target component carriers to which a User Equipment (UE) is to be handed over, and notifying the UE of information about the target component carriers through a source eNB; and after receiving a dedicated random access preamble sent by the UE, sending a random access response message on at least one component carrier in the target component carriers. The terminal equipment includes: a handover command receiving unit, a sending unit, and a random response receiving unit. Therefore, in a random access procedure of cell handover, the eNB is capable of determining downlink component carriers that a UE monitors, thereby increasing utilization rate of downlink resources.
