This invention relates to a method for sharing real-time IPTV content to a mobile terminal for playback, belonging to the field of wireless communication and terminals. The method includes: the IPTV device and the mobile terminal sending a STUN request to a public STUN server to bypass NAT and automatically obtain the corresponding public IP address; the IPTV device and the mobile terminal establishing an IPSec encrypted tunnel based on the IPSec protocol; the IPTV device receiving the operator's playback stream, extracting video and audio data, re-encapsulating it into RTP format, encrypting it, and transmitting it to the mobile terminal through the IPSec encrypted tunnel; the mobile terminal decrypting and verifying the integrity of the data packets, extracting the RTP payload, and playing the corresponding video and audio data in real time; the mobile terminal sending control commands to the IPTV device through the IPSec encrypted tunnel; the IPTV device parsing the control commands and calling an API to switch channels, synchronously updating the electronic program guide information to the mobile terminal. This method enables mobile devices to remotely receive and play television channel content from a home IPTV device via the public network, overcoming spatial limitations.

To carry 5G QoS traffic flows over an IPsec Security Association (SA) within a WLAN network, a STA is configured to encode a frame to include a Traffic Classification (TCLAS) element that includes a frame classifier field. The frame classifier field can include a classifier type subfield and a classifier parameter subfield. To identify and filter 5G QoS traffic flows carried over an IPsec SA, the STA can set the classifier type subfield to a predetermined value (e.g., 11) to indicate that an IPsec SA parameter is included in the classifier parameter subfield, and include a Security Parameter Index (SPI), a destination IP address, and an IPsec protocol within the classifier parameter subfield.
