Abstract: The present disclosure provides a network node data scheduling method, an apparatus, and a system. The method includes the following steps: obtaining, by user equipment, first system information of a current serving micro network node, determining, by the user equipment, a first shared carrier of a serving micro network node group according to the first system information, and transmitting, by the user equipment, service data according to the first system information by using the first shared carrier; when it is determined that a preset cell handover condition is met, handing over, by the user equipment, to a target cell, obtaining second system information of a target micro network node corresponding to the target cell, and transmitting the service data in the target cell according to the second system information by using a second shared carrier of a micro network node group to which the target micro network node belongs.

Abstract: Embodiments of the present invention provide a cell handover method and a device. so that the target eNB uses a current serving small node as a user plane serving node after UE is handed over and uses the target eNB as a control plane serving node after the UE is handed over; receiving a handover request acknowledgment sent by the target eNB; and sending offloading configuration information of the current serving small node to the current serving small node, and sending RRC reconfiguration information of the UE to the UE, so that offloading configuration is performed separately by the current serving small node and the UE. This avoids a problem that in a cell handover process, a transmission resource required for transmission increases and a delay is relatively great because the current serving small node forwards a large amount of data to the target eNB.

Abstract: This application discloses a communication method, apparatus, and system, and relates to the field of communication technologies. The method includes: obtaining a second key used for communication authentication with a second node, where the second key is different from a preconfigured first key; receiving, from the second node, a release request for a first communication connection, where the first key is used for communication authentication on the first communication connection; and sending a connection establishment request to the second node, where the connection establishment request is used to request to establish a connection based on the second key. The method provides a technical solution in which the first node and the second node release a connection after determining an updated key, and establish a connection by using the new key, to implement an authentication procedure in a multi-communication scenario convergence scenario.

Abstract: In a communication method, when MAC addresses in a plurality of VSI messages conflict, in response to only some of the VSI messages, a VSI message receiving end sends an action response message carrying a conflicting MAC address. In this way, a device that can correctly decrypt the action response message can decrypt, for a few times, ciphertext information in received action-request messages using a key of the device.

Abstract: Embodiments of the present application provide a broadcast mechanism-based unicast session system, method, and apparatus, a computer-readable storage medium, and a vehicle, to establish a unicast session carried through broadcast between an initiator device and a responder device. An extension identifier of the initiator device or the responder device is added to a unicast request message, a unicast response message, or a unicast acknowledgment message sent in a broadcast manner, to avoid a session error caused by a MAC identifier conflict of the initiator device or the responder device, thereby improving reliability of the unicast session.
