Multi-flow associated transmission method, apparatus, and system

This invention describes a method for a network's session management system to handle multiple related data streams, like those for a single video call or a complex application. It works by identifying these streams as a group and then applying specific quality-of-service rules to ensure they are all transmitted together with the required performance, such as low latency or high bandwidth. The system uses group identifiers and QoS policies to manage these associated transmissions.
