Claim:
1. A method for an electronic device to perform multipath transmission control protocol (MPTCP) communication with a remote endpoint, the method comprising: exchanging a TCP handshake with an MP_CAPABLE option with the remote endpoint, wherein the TCP handshake with the MP_CAPABLE option establishes a MPTCP session and with the remote endpoint and establishes a first MPTCP subflow of the MPTCP session; communicating application data with the remote endpoint via the first MPTCP subflow; terminating the first MPTCP subflow of the MPTCP session by including a TCP FIN flag with data communicated via the first MPTCP subflow, wherein after terminating the first MPTCP subflow the MPTCP session comprises zero MPTCP subflows between the electronic device and the remote endpoint; and maintaining MPTCP session state information at the electronic device with zero MPTCP subflows between the electronic device and the remote endpoint after terminating all MPTCP subflows of the MPTCP session.
