Publication number: 20200052992Abstract: A method for detecting aggressive signal transmission signatures in a wireless communication network is provided. The network includes at least one station, at least one access point, and at least one non-cooperative transmission source. The method includes steps of generating a matrix of each instance of request-to-send (RTS) messages received by the access point during a specified observation cycle, recording, in a memory of the access point, a number of cumulative RTS messages received from the station, calculating a cumulative distribution function (CDF), based on the recorded RTS message instances in the memory, for a probability of the presence of an aggressive transmission signal by the non-cooperative transmission source within a transmission range of the access point, and determining the presence of the aggressive transmission signal based on the calculated CDF being greater than a predetermined threshold.Type: ApplicationFiled: October 16, 2019Publication date: February 13, 2020Inventors: Dorin Gheorghe Viorel, Jennifer Andreoli-Fang, Belal Hamzeh, Josh Redmore, Carey Sonsino

Publication number: 20200037291Abstract: A method for allocating aggressive signal carriers in a target band of a wireless communication network is provided. The network includes at least one long term evolution (LTE) node and at least one non-LTE transmission source. The target band includes at least two adjacent pairs of contiguous radio frequency (RF) channels. The method includes steps of scanning each contiguous RF channel of the target band to measure a respective value of non-LTE RF energy therein, determining, from the measured non-LTE RF energy, that a first one of the contiguous RF channels is occupied by a non-LTE carrier, and allocating an LTE carrier to a second one of the contiguous RF channels, different than the first one of the contiguous RF channels, based on the determination.Type: ApplicationFiled: October 4, 2019Publication date: January 30, 2020Inventors: Dorin Gheorghe Viorel, Jennifer Andreoli-Fang, Neeharika Allanki

Publication number: 20190261416Abstract: A method for detecting aggressive signal transmission signatures in a wireless communication network is provided. The network includes at least one cooperative device, an access point, and at least one non-cooperative device. The method includes steps of generating a matrix of at least 8 bits configured to register each instance of at least one of a clear-to-send frame and a request-to-send frame transmitted between the at least one cooperative device and the access point during a specified duration, calculating a cumulative distribution function based on the registered instances within the generated matrix for a probability of the presence of an aggressive transmission signal by the at least one non-cooperative device within a measurable vicinity of one or more of the cooperative device and the access point, and determining the presence of the aggressive transmission signal based on the calculated cumulative distribution function being greater than a predetermined threshold.Type: ApplicationFiled: February 21, 2019Publication date: August 22, 2019Inventors: Dorin Gheorghe Viorel, Jennifer Andreoli-Fang, Belal Hamzeh, Josh Redmore, Carey Sonsino

Patent number: 10334630Abstract: A method is provided for managing a wireless network traffic by comprising designating a first resource block of a first base station for access by a random access channel (RACH). The method additionally comprises designating a first plurality of random access subframes associated with the first resource block for access by a user-over-control plane message, and receiving a random access signal at the first base station over a subframe from an endpoint. The random access signal is received on the RACH using a wireless network and is attempting to access one of the first plurality of designated random access subframes. Further, the method comprises determining if the random access signal is a user-over-control plane message, and processing the random access signal on the one of the first plurality of designated random access subframes.Type: GrantFiled: December 10, 2012Date of Patent: June 25, 2019Assignee: FUJITSU CONNECTED TECHNOLOGIES LIMITEDInventors: Dorin Gheorghe Viorel, Akira Ito, Paul Bucknell, Chenxi Zhu

Publication number: 20190053278Abstract: A wireless communications system provides coordinated multi point transmission over a channel of a wireless transmission medium. The system includes a central controller having a processor and a memory, a first cell region having a first communications node disposed therein, and a plurality of neighboring cell regions disposed about the first cell region. Each of the plurality of neighboring cell regions includes a second communications node disposed therein. The system includes a plurality of user equipment devices disposed within an overlapping region of the first cell region and one of the neighboring cell regions. The central controller is configured to assign the first communications node to be an anchor transmission point of a coordinated set of transmission points. The anchor transmission point is configured to perform carrier sensing on the channel. The coordinated set of transmission points includes the first communications node and at least one second communications node.Type: ApplicationFiled: August 8, 2018Publication date: February 14, 2019Inventors: Balkan Kecicioglu, Dorin Gheorghe Viorel
