Abstract: Example transmission rate control methods and apparatus are described. One example method includes obtaining a user equipment aggregate maximum bit rate (UE-AMBR) by a master base station. The master base station determines, based on the UE-AMBR, a first UE-AMBR used for the master base station and a second UE-AMBR used for a secondary base station. The master base station sends the second UE-AMBR to the secondary base station, and sends instruction information used to instruct the secondary base station to control data splitting for the master base station to the secondary base station. In this application, a transmission rate between each base station and a UE is controlled by allocating a UE-AMBR.

Abstract: Embodiments of the present disclosure provide a data transmission method, apparatus, and device. The method includes: performing, by a terminal, encryption and integrity protection on a data packet by using a public key of a network device and a private key of the terminal, where the data packet includes user data; and sending, by the terminal, the data packet to the network device, to send the user data to a server by using the network device. Encryption and integrity protection are performed on the data packet respectively by using the public key of the network device and the private key of the terminal, and when no radio resource control RRC connection is established, the data packet is sent to the network device.

Abstract: This application relates to the field of communications technologies, and discloses example redirection methods and apparatuses to ensure that a call drop does not occur after UE is redirected. One example method includes determining, by a base station, that a redirection operation needs to be performed on user equipment UE, and then instructing a core network to reserve a guaranteed bit rate (GBR) bearer or a voice service bearer that is corresponding to the UE. The UE is then instructed to reserve the GBR bearer or the voice service bearer that is corresponding to the UE. After the UE is redirected to a new base station, the voice service bearer of the UE is reserved on a UE side.

Abstract: This application provides a tunnel binding based communication method and a network device. The method includes: transmitting, by a first network device, a service packet to a second network device using a first binding tunnel including a first tunnel and a second tunnel; and when the first tunnel is faulty or transmission quality of the first tunnel does not meet a preset condition, transmitting, by the first network device, a service packet to the second network device using a second binding tunnel including a backup tunnel of the first tunnel and the second tunnel. Therefore, if a tunnel in an original binding tunnel is faulty, a tunnel binding based high-bandwidth service continues to be provided using another binding tunnel constituted by a backup tunnel of the faulty tunnel and a fault-free tunnel. Compared with the prior art, this application can improve high-bandwidth communication reliability and user satisfaction.

Abstract: Embodiments of the present invention provide a wireless local area network WLAN measurement and reporting method, and a related device. The method includes: acquiring, by a user terminal, WLAN group information, where the WLAN group information indicates at least one WLAN group; determining, by the user terminal, whether at least one WLAN in the WLAN group satisfies WLAN measurement configuration information; and reporting, by the user terminal, a measurement result of the at least one WLAN in the WLAN group to a base station when the at least one WLAN in the WLAN group satisfies the WLAN measurement configuration information. Therefore, a signaling resource can be saved, thereby reducing signaling load caused by simultaneous reporting of a large quantity of WLAN measurement results.
