AI Technical Summary
Technical Problem
Existing technologies face challenges in accurately exchanging local address information during media communication sessions, leading to potential inaccuracies in PDU set size values due to differences between local and global IP addresses.
Method used
Incorporating the local IP address type into the RTP header extension for PDU Set marking, allowing intermediate network devices to adjust PDU set size values accordingly, ensuring accurate delivery of packets in media communication sessions.
Benefits of technology
This approach ensures accurate calculation and transmission of PDU set size values, ensuring that all packets of a common PDU set are delivered together, thereby enhancing the reliability and efficiency of media communication sessions.

Abstract
A first client device may participate in a media communication session with a second client device. The first client device may receive a local IP address type of the second client device. The first client device may provide the local IP address type to an intermediate network device. In this manner, the intermediate network device may use the local IP address type to calculate a protocol data unit (PDU) set size (PSSize) based on the local IP address type. The intermediate network device may add the calculated PSSize value to a tunnel header of a tunnel packet that encapsulates a packet including media data sent by the second client device to the first client device. In this manner, other network devices may receive accurate values for the PSSize when media data is exchanged via network tunnels, to ensure that all packets of a common PDU set are delivered together.
