    Abstract: In this invention we disclose methods of automatically configuring a wireless node when it initially powers on and seeks to integrate into an existing wireless network. The wireless node could be part of an ad hoc, software defined network. One such network could be LTE network. The auto-configuration methods disclosed herein can be executed on wireless nodes throughout their operation. In addition, the methods herein allow a node to intelligently choose which network to join when there is more than one available network. In alternate embodiments, the methods disclosed could be used to create a new configuration based on changed environmental conditions, location or node capability change. These embodiments allow wireless nodes to migrate to better quality connections if they become available.

    Abstract: A method is disclosed for providing IP access across packet data network gateways (PGWs), comprising: receiving, from a UE, at a coordinating node, an attach request; sending a request to create a first new session to a first PGW; sending a request to create a second new session to a second PGW; receiving, from the first PGW and at the coordinating node, a first request for policies for the UE; receiving, from the second PGW and at the coordinating node, a second request for policies for the UE; opening a first data tunnel from the coordinating node to the first PGW; opening a second data tunnel from the coordinating node to the second PGW without closing the first data tunnel; and opening a data tunnel between the UE and the coordinating node for providing IP access to both the first PGW and the second PGW.

    Abstract: A Long Term Evolution (LTE) receiver performing a half cyclic prefix (CP) shift on received subframes is disclosed, comprising: an analog to digital conversion (ADC) module; a cyclic prefix (CP) removal module coupled to the ADC module configured to retain a portion of cyclic prefix samples; a fast Fourier transform (FFT) module configured to receive samples from the cyclic prefix removal module, and to perform a FFT procedure on the received samples using a FFT window, the FFT window being shifted ahead based on the retained portion of cyclic prefix samples, to output an orthogonal frequency division multiplexed (OFDM) symbol; and a rotation compensation module coupled to the FFT module, the rotation compensation module configured to perform phase de-rotation of the OFDM symbol.

    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.

    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.
