Abstract: A gateway situated between the RAN and the core network may provide 2G/3G/4G/Wi-Fi convergence for nodes in a network on a plurality of radio access technologies. In some embodiments, a convergence gateway is described that allows for legacy radio access network functions to be provided by all-IP core network nodes. A multi-RAT gateway provides 2G/3G Iuh to IuPS interworking, IuCS to VoLTE interworking via a VoLTE proxy, IuPS and 4G data local breakout or S1-U interworking, and 2G A/IP and Gb/IP to VoLTE and S1-U/local breakout interworking. The multi-RAT gateway may thereby support all voice calls via VoLTE, and all data over S1 or local breakout, including VoLTE. The multi-RAT gateway may provide self-organizing network (SON) capabilities for all RATs. A multi-RAT base station may provide 2G and 3G front-end interworking to Iuh.

Abstract: The use of wireless backhaul poses special challenges for in-vehicle base stations. Users that are connected to an in-vehicle base station expect continuous service, even as the in-vehicle base station passes in and out of different wireless backhaul coverage zones, such as when a train passes from a train station with good coverage to a tunnel with poor coverage. The base station thus needs seamless backhaul handover. A system that enables an in-vehicle base station to receive continuous service across different backhaul coverage zones is needed. To solve this problem, a system enabling handover is described. The system involves double-tunneling mobile device data packets in an ESP-UDP IPsec tunnel encapsulated in a GTP-U tunnel. Traffic is transmitted from a mobile device to a specially configured base station that encapsulates mobile device data packets and sends them to the network via wireless backhaul using an LTE UE modem connection.

Abstract: A method is disclosed for tearing down a TCP connection between a transmission control protocol (TCP) client in a radio access network (RAN) and a TCP server, comprising: receiving, at the TCP client, an indication to close the TCP connection; sending, from the TCP client to the TCP server, a TCP segment with a FIN bit set to indicate termination of the TCP connection; and closing, at the TCP client, the TCP connection without waiting for double the maximum segment lifetime period, thereby releasing the radio bearer resources and achieving radio bearer resource optimization.

Abstract: A method for localizing a voice call is disclosed, comprising: receiving an originating leg setup message for an originating leg bearer from the first base station for a first user equipment (UE); creating a first call correlation identifier and storing the first call correlation identifier in association with the first UE; extracting a second call correlation identifier from a terminating leg setup message for a terminating leg bearer received from the core network; determining a real time protocol (RTP) localization status for the originating leg bearer and the terminating leg bearer based on matching the second call correlation identifier of the terminating leg against the stored first call correlation identifier of the originating leg; and sending transport layer assignment messages to the first base station to redirect RTP packets from the first UE to the second UE via the terminating leg bearer without the RTP packets transiting the core network.

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). The multi-RAT base station gateway determines if the UE is capable of MPTCP to provide MPTCP. 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.
