Abstract: Provided are a data transmission method and apparatus. The method includes: detecting, by a source base station, that link quality of a connection with a terminal degrades; sending data unsuccessfully transmitted by a DU via a downlink data frame to a target base station through a CU, and transmitting the data unsuccessfully transmitted to the terminal through the target base station; or receiving, by the target base station, a link quality degradation message of an original base station so as to stop sending offload data to the source base station and transmitting the data unsuccessfully transmitted indicated by a maximum serial number of the data which has been transmitted continuously and successfully in the message to the terminal.

Abstract: Provided are a method and a device for load information interaction, a processor and a storage medium. The method includes: sending, by a first network node, a load request message to a second network node, where the load request message is used for indicating configuration information used by the second network node in reporting load information to the first network node; and receiving, by the first network node, the load information reported by the second network node according to the configuration information. The second network node and the first network node belong to different logical nodes in a network. The technical problem that load management cannot be performed when the second network node and the first network node belong to different logical nodes in related technology is solved, and the maximum performance of the network is fully exhibited.

Abstract: Provided are a connection method, a configuration updating method, a control plane device and a user plane device. The method includes: transmitting, by a control plane device, a first request message for establishing a connection to a user plane device, where the first request message for establishing the connection includes information about the control plane device; and transmitting, by the user plane device, a first response message indicating that the connection is successfully established or a first response message indicating that the connection fails to be established to the control plane device, where the first response message indicating that the connection is successfully established includes information about the user plane device, and the first response message indicating that the connection fails to be established includes the information about the user plane device and a reason why the connection fails to be established. Further provided is a storage medium.

Abstract: Provided are a detection method and device for link keep-alive between an Access Controller (AC) and an Access Point (AP). The method includes: setting a maximum permissible heartbeat keep-alive failure number; and performing link keep-alive detection between the AC and the AP based on the maximum permissible heartbeat keep-alive failure number by virtue of a heartbeat message or message retransmission. By the solution, a maximum permissible heartbeat keep-alive failure number is set, and a maximum retransmission interval is set for link keep-alive detection between the AC and the AP based on the maximum permissible heartbeat keep-alive failure number and a heartbeat keep-alive period, so that the problem that the AP frequently gets offline and frequently re-accesses the AC due to link quality reduction to seriously impact user experiences can be effectively solved.
