Network function entity and wireless communication method thereof and storage medium

A multi-access edge computing (MEC) net element comprising:

• a memory;
• at least one processor for executing instructions in the memory, wherein the at least one processor is configured to:
• receive video data packets from a server and buffer the video data packet during a process of video data transmission between a user equipment and the server via the wireless network;
• acquire status information related to a data transmission link during a process of video data transmission between a user equipment and a server via the wireless network;
• and
• adjust the video data transmission between the user equipment and the server based on the status information,
• wherein the status information further comprises information about a status of a core network control plane in the wireless network,
• wherein the at least one processor is configured to adjust the video data transmission between the user equipment and the server based on the status information comprises performing operation to reduce influence of a change of the transmission link on downlink data transmission based on a determination based on the information about the status of the core network control plane that the transmission link between the user equipment and the base station is changed,
• wherein the status information comprises information that the user equipment performs handover of a target cell and there is a link speed limit to the target cell that is handed over to, wherein the at least one processor is configured to adjust the video data transmission between the user equipment and the server based on the status information at least by:
• process video data received from the server to reduce a size of the video data to be transmitted to the base station, and
• transmit the processed video data to the base station.
