Abstract: A method and a device for establishing an evolved packet system EPS bearer are disclosed. The method includes establishing, by a first base station to which UE belongs, a first EPS bearer based on a first CC for the UE, wherein the first EPS bearer is an EPS bearer between the first base station and the UE; and instructing, by the first base station, a second base station to establish a second EPS bearer based on a second CC for the UE, wherein the second EPS bearer is an EPS bearer between the second base station and the UE. The present invention enables the UE to aggregate carriers of different frequency ranges from the first base station to which the UE belongs and the second base station to which the UE belongs to transmit data, thus improving the throughput of the data transmitted by 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: Example communication methods and apparatus are described. One example method includes determining by a terminal that a first transmission resource conflicts with a second transmission resource. The first transmission resource is a resource used by the terminal to send first information to a first network side device. The first network side device corresponds to a first user identity supported by the terminal. The second transmission resource is a resource used by the terminal to send second information to a second network side device. The second network side device corresponds to a second user identity supported by the terminal. The terminal sends the first information on the first transmission resource. The terminal cancels sending the second information on the second transmission resource. Alternatively, the terminal sends the second information on a third transmission resource, where the third transmission resource is a resource before or after the second transmission resource.

Abstract: A communication method includes establishing, by a communication device, a first connection to a first network device and a second connection to a second network device. The first connection and the second connection are used to process a first service. The method also includes sending, by the communication device, first information to the first network device based on the communication device determining that a second service needs to be processed. The second service is different from the first service. The first information is used to request to disable the first connection or the second connection, or the first information is used to indicate the communication device to establish a third connection to a third network device. The third connection is used to process the second service.

Abstract: A method may be applied to a terminal device that supports a first communication system and a second communication system. The first communication system corresponds to a first user identity, and the second communication system corresponds to a second user identity. The method includes: a terminal device receiving a first message in a first communication system, where the first message indicates to perform DAPS handover between a source cell and a target cell in the first communication system. In response to determining that a capability available for the first communication system cannot support the DAPS handover, the terminal device suspends communication with the source cell in the first communication system, and is handed over to the target cell in the first communication system.

Abstract: Embodiments of this application provide a resource preemption method, an apparatus, and a system, to reduce a quantity of times of frequent resource preemption, and improve resource security. In one example, a first terminal device obtains a first time interval and a second time interval, and preempts or determines not to preempt a first resource according to a first preset rule. The first resource is a resource reserved by a second terminal device or a resource reserved for a first service to be transmitted by the first terminal device. The first time interval is a time interval related to the first resource. The second time interval is used to indicate a preemption forbidden time. The first preset rule is determined based on the first time interval and the second time interval.
