Abstract: The present disclosure discloses a data transmission method, device, and system, and belongs to the field of communications technologies. The method includes: receiving a data packet sent by user equipment, where the data packet carries indication information used to instruct a base station to establish a specified data connection to the user equipment; generating a first key of the user equipment based on the indication information and a public key of the base station; and performing data transmission with the user equipment based on the first key of the user equipment. According to the data transmission method, the transmitted data can be encrypted and decrypted when there is no radio resource control connection between the base station and the user equipment, thereby improving data transmission security while ensuring data transmission efficiency.

Abstract: The present disclosure relates to the field of mobile communications technologies, and in particular, to an offloading method and an apparatus. In this solution, when a terminal is in a handover process, a destination cellular network node sends, to the terminal, configuration information of a WLAN AP managed by the destination cellular network node; and then the terminal selects a destination WLAN AP from WLAN APs managed by the destination cellular network node, and offloads data of the destination cellular network node to the destination WLAN AP. Therefore, the destination WLAN AP selected by the destination cellular network node can be received before a handover is completed, thereby ensuring service continuity and improving service quality of a terminal.

Abstract: This application provides a management system, a method and an apparatus. A second network management device determines an expectation target and an expectation object, where the expectation target is user quality of experience that the expectation object needs to satisfy, and the expectation object includes at least one of the following: an area, a user group, a user, a service, or a network. The second network management device sends the expectation target and the expectation object to a first network management device. Correspondingly, the first network management device receives the expectation target and the expectation object. The first network management device manages a network to satisfy the expectation target. According to the intent management method and the apparatus provided in this application, the user quality of experience can be improved.

Abstract: Embodiments of this application provide an information transmission method, an apparatus, and a system. A first network device sends, to a terminal device, conditional handover configuration information that includes information about candidate cells and a handover trigger condition; after receiving the conditional handover configuration information and performing a conditional handover, the terminal device sends, to a second network device, a first failure cause value corresponding to a candidate target cell and/or a second failure cause value corresponding to a to-be-determined cell during the conditional handover; and the second network device receives the first failure cause value and/or the second failure cause value from the terminal device, and sends the first failure cause value and/or the second failure cause value to the first network device.

Abstract: In a method for resolving PCT conflicts in a new radio (NR) network, synchronization signal and PBCH (Physical Broadcast Channel) blocks (SSB) and corresponding physical cell identifiers (PCIs) are utilized. In the method, a first PCI corresponds to a first SSB and a second PCI corresponds to a second SSB. An access network device determines, based on the first PCI and the second PCT, that the first PCI conflicts with the second PCI. In this way, PCI conflicts in an NR system can be detected to improve the success rate and to reduce the call drop rate in a terminal handover.
