Publication number: 20190253844Abstract: Methods and apparatus for efficiently establishing communications connections, e.g., for a secondary application, are described. A device to device communications network has established routing paths, e.g., corresponding to a first application. Different segments of the network use different gateways. Individual communications devices within a segment of the network may have incomplete information on the routing within the segment. A wireless communications device advertises the gateway device which it uses for the first application. A first communications device seeking to establish a communications connection with a second communications device for a second application uses obtained gateway information to make transmission and/or routing decisions, e.g., identifying a third communications device which can bridge a routing path gap between two segments of the network.Type: ApplicationFiled: April 22, 2019Publication date: August 15, 2019Inventors: Tuan TA, Vidur Bhargava

Patent number: 10333612Abstract: A method, wireless device and computer program product for expanding the coverage of a cellular network. A wireless device (e.g., cellular telephone) is able to communicate with a base station in a cell of the cellular network over a non-cellular interface via another wireless device in a cell through the use of multi-hopping. A wireless device may request permission to communicate with the base station over a non-cellular interface via hopping off another wireless device when its signal strength is below a threshold. Alternatively, a wireless device may receive a request to communicate with the base station over a non-cellular interface via hopping off the wireless device that sent the request when that wireless device has excess capacity in its bandwidth with the base station. By enabling wireless devices to communicate with a base station in such a manner, the effective capacity of the cellular network is expanded and the effective capacity of the cellular network is improved.Type: GrantFiled: September 25, 2017Date of Patent: June 25, 2019Assignee: Board of Regents, The University of Texas SystemInventors: Vidur Bhargava, Sriram Vishwanath, Jubin Jose

Patent number: 10206228Abstract: A method, system, or computer program product to enhance the performance of multi-hop cellular networks or other wireless networks is provided. A wireless device (e.g., cellular telephone) is able to communicate with a base-station in a cell of the cellular network over a non-cellular interface via another wireless device in the cell through the use of multi-hopping. By enabling wireless devices to communicate with a base station in such a manner, the effective coverage area of the cellular network is expanded and the effective capacity of the cellular network is improved. Distributed routing, device management, adaptive scheduling, and distributed algorithms can be used to enhance the overall performance of multi-hop cellular networks.Type: GrantFiled: March 6, 2018Date of Patent: February 12, 2019Assignee: Board of Regents, The University of Texas SystemInventors: Vidur Bhargava, Sriram Vishwanath, Jubin Jose

Patent number: 10205505Abstract: Methods and apparatus for supporting efficient communications of time varying data are described. A wireless device monitors to detect receipt of a first identifier, e.g., an LTED OTACode, via a first network interface, said first identifier corresponding to first information that is available via the first network, said first information indicating a source of first time varying data and a description of the first time varying data. The wireless device monitors to detect receipt of a second identifier, e.g., a hash value, via a second network interface, e.g., a WIFI, interface. The wireless device determines if the first identifier was received on the first interface and if a second identifier, corresponding to the first identifier, was received on the second interface. The wireless device makes a decision whether or not to retransmit the second identifier. The wireless device retrieves, uses and/or supplies the first time varying data to other devices.Type: GrantFiled: August 31, 2016Date of Patent: February 12, 2019Assignee: M87, Inc.Inventors: Jonas Michel, Vidur Bhargava, Christine Julien

Publication number: 20180262962Abstract: Methods and apparatus for efficiently communicating network connectivity information in a communications system are described. Two types of signals with different characteristics, e.g., long range synchronous beacons, e.g., LTE-D beacons, and short range asynchronous beacons, e.g., WiFi beacons, are used in combination to advertise network connectivity information and accelerate the acquisition of a routing path for a communications device to a device serving as a gateway for a infrastructure network. Reception of a first type signal triggers monitoring for a second type signal, and a received second type signal communicates information used to determine a communications path to a gateway device.Type: ApplicationFiled: May 13, 2018Publication date: September 13, 2018Applicant: M87, Inc.Inventors: Tuan Ta, Vidur Bhargava
