Abstract: Embodiments of the present invention relate to an RRC connection method and a serving node. In the embodiments, an RRC connection is established between an anchor node and a UE. Therefore, when a serving node of the UE is switched, a connection between an MME and the anchor node does not change. When the MME needs to send a paging message, the MME does not need to send the paging message to all base stations in a TA area that corresponds to the paging message, thereby effectively reducing signaling load of a core network.

Abstract: A method, a system and an apparatus can be used for transmitting data in a CA manner. A first base station currently serving a user equipment (UE), creates EPS bearers under different component carriers CC Groups for the UE. The UE sets different access stratum entities corresponding to the CC Groups to process data in the process of creating the EPS bearers. The UE determines, when transmitting or receiving data, a corresponding CC Group according to an EPS bearer that bears the data. An access stratum entity corresponding to the CC Group processes the data that needs to be transmitted or received, a site is a first base station currently serving the UE or a second base station currently serving the UE.

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.

Abstract: Embodiments of the present invention disclose a method and an apparatus for determining an active time of UE, where the method includes: acquiring extension information of a DTX active time of a base station; and adjusting a DTX active time of the UE according to the extension information, and using an overlapped time between the DTX active time of the UE and a DRX active time of the UE as an active time of the UE for listening on a PDCCH channel. The UE can learn a latest DTX condition according to a change of the DTX on a base station side in a manner of acquiring extension information of a DTX active time of the base station, and therefore can determine a correct active time of the UE with reference to DRX of the UE, thereby ultimately ensuring QoS of the UE.
