Multipath TCP (MPTCP) is one of the key technologies that can improve the throughput performance by exploiting multiple path communications. This letter proposes an offloading by restriction (OBR) scheme to enhance the throughput by offloading data traffic optimally when fifth generation (5G) new radio (NR) and LTE communication paths are aggregated. The proposed OBR scheme also considers interaction with MPTCP congestion control and scheduling algorithms, thus can be added without modification to MPTCP. Simulation results show that the proposed OBR scheme can provide a significant throughput gain compared to the MPTCP control scheme linked increases algorithm and multipath offloading scheme multipath offloading algorithm.
