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: A system for an enhanced X2 interface in a mobile operator core network is disclosed, comprising: a Long Term Evolution (LTE) core network packet data network gateway (PGW); an evolved NodeB (eNodeB) connected to the LTE PGW; a Wi-Fi access point (AP) connected to the LTE PGW via a wireless local area network (WLAN) gateway; and a coordinating node positioned as a gateway between the LTE PGW and the eNodeB, and positioned as a gateway between the LTE PGW and the Wi-Fi AP, the coordinating node further comprising: a network address translation (NAT) module; and a protocol module for communicating to the eNodeB and the Wi-Fi AP to request inter-radio technology (inter-RAT) handovers of a user equipment (UE) from the eNodeB to the Wi-Fi AP and to forward packets intended for the UE from the eNodeB to the Wi-Fi AP.

Abstract: A method is disclosed for avoiding unnecessary keepalive data transfers, comprising: receiving, at an upstream TCP connection endpoint in a radio access network (RAN) from an operator core network, an Internet Protocol (IP) packet; performing, at the upstream TCP connection endpoint, shallow packet inspection on the IP packet; and forwarding the IP packet to the downstream TCP connection endpoint in the RAN if the IP packet is not a keepalive packet, based on the performed shallow packet inspection. The upstream TCP connection endpoint in the RAN may be one of a nodeB, an eNodeB, a base transceiver station (BTS), a coordinating server, and a mobile edge computing (MEC) gateway. The downstream TCP connection endpoint in the RAN may be one of the nodeB, the eNodeB, or the base transceiver station (BTS).

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: A method for congestion mitigation via admission control in a shared-backhaul telecommunications network is disclosed, comprising: assessing a congestion state in a multi-node radio access network having a shared backhaul connection, the congestion state based on congestion of the shared backhaul connection; retrieving an admission control policy based on the congestion state of the shared backhaul connection; performing a policy action of the admission control policy at a first base station acting as a gateway for the multi-node radio access network with respect to the shared backhaul connection; and sending the admission control policy to other nodes in the multi-node radio access network, thereby causing the other nodes to perform the policy action, wherein the policy action is denying a request from a user equipment to attach to the radio access network.
