Abstract: Systems, methods and computer software are disclosed for providing Multipath Transmission Control Protocol (MPTCP) with mesh access. A multi Radio Access Technology (RAT) base station gateway having a MPTCP proxy, proxies an initial MPTCP connection from a User Equipment (UE).

When the UE is capable of MPTCP, then the multi-Rat base station provides a Wi-Fi connection and an LTE connection. When the UE is not capable of MPTCP, then the multi-RAT base station provides an LTE connection.
