A recently granted patent (Publication Number: US11930547B2) discloses a method and apparatus for managing multipath transmission control protocol connections in a network environment. The method involves connecting a network node proxy to a terminal device and a master node, intercepting the transmission control protocol handshake, and configuring main and secondary node bearers. The user plane function sends notifications to trigger the master node to start a secondary node addition procedure. The apparatus includes at least one processor and memory storing instructions for establishing connections, terminating sub-flows, and managing multipath transmission control protocol connections efficiently.

Furthermore, the patent details additional steps such as establishing a connection to the content server, utilizing a transparent multipath transmission control protocol proxy, and mapping quality of service configurations for sub-flows. The apparatus also includes instructions for mapping sub-flows to different quality of service flows based on specific identifiers. By optimizing the routing and management of multipath transmission control protocol connections, the method and apparatus described in the patent aim to enhance network efficiency and performance, particularly in scenarios involving multiple addresses and quality of service requirements.
