Abstract: Embodiments of the present invention provide a radio bearer processing method, user equipment, and a base station. The method includes: suspending, by user equipment, data transmission of a bearer on a second base station; and sending, by the user equipment, a suspend indication to a first base station, where the suspend indication is used to indicate that the user equipment has suspended the data transmission of the bearer on the second base station. When the data transmission of the bearer on the second base station is resumed, the related protocol entity does not need to be re-established, thereby improving utilization of radio bearer resources.

Abstract: The present invention discloses a data transmission system. The first device performs, at a cellular network PDCP layer of the first device, security processing on to-be-transmitted data based on a transmit end-based first policy, to generate a PDU, and sends the PDU to the relay UE, where the first policy is a security processing policy agreed on by the first device and the second device, and the to-be-transmitted data is data that the first device needs to transmit to the second device. The relay UE sends the PDU to the second device. The second device performs, at a cellular network PDCP layer of the second device, security processing on the PDU based on a receive end-based first policy, to obtain the to-be-transmitted data, where the cellular network PDCP layer of the first device is a peer to the cellular network PDCP layer of the second device.

Abstract: Embodiments of this application relate to the communications field, and provide a method and an apparatus for data transmission in multiple carriers. Uplink access carriers may be dynamically adjusted when the uplink load is heavy. The method includes receiving, by a terminal device, at least one piece of indication information from an access network device, where the at least one piece of indication information indicates at least one access control parameter. The method further includes selecting, by the terminal device, an access carrier from at least two candidate carriers based on the at least one access control parameter, where the at least two candidate carriers are in different frequency bands.

Abstract: A tunnel establishment method and apparatus is disclosed. Even if an entity for executing the solution is not changed, a type of a tunnel established for each service of a terminal may be the same or may be different. For example, a first tunnel and a second tunnel may be established for a current service of the terminal, and a third tunnel may be established for a next service of the terminal. This eases congestion in a backbone network between a secondary access network node and a primary access network node. Alternatively, this avoids using a directly connected tunnel as a tunnel established between the secondary access network node and a core network user plane node when a core network control plane node needs to receive and send too much path switching signaling.

Abstract: A service transmission method is provided. A first base station, which establishes an RRC connection with a UE, sends a request message to a second base station which is at least one of base stations serving the UE, where the request message includes service information, where the service information includes QoS information of a service and/or configuration information of an RB, and the request message instructs the second base station to perform resource configuration according to service information. The first base station sends a configuration message to the UE, where the configuration message includes configuration list information of the RB and/or cell information of the offload base station.
