Patent number: 11075742Abstract: A duplex frequency is supplemented by providing simplex frequencies and distributing a data load among them. A server initially communicates with a communications device using a duplex channel. A scheduler of the server determines when it is no longer optimal to use the single duplex channel, and distributes data among the duplex channel and the simplex channels. Before sending this data through multiple channels, the server first sends a schedule to the communications device to inform which bits of data are coming through which channels at which times. The scheduler compiles this schedule and sends it to the communications device through the duplex channel. A descheduler within the communications device receives the schedule and alerts the communications device to start receiving data on other simplex channels. The descheduler then puts the bits of data in order as they stream in across the duplex and simplex channels.Type: GrantFiled: July 3, 2019Date of Patent: July 27, 2021Assignee: AT&T MOBILITY II LLCInventors: Arthur Richard Brisebois, Yung Shirley Choi-Grogan, Melvin D.

Patent number: 10848227Abstract: Switching between and/or combining various multi-transceiver wireless communication techniques based on a determined characteristic of a network or a wireless link is described herein. As an example, a characteristic such as signal to noise ratio (SNR), multi-path scattering, available bandwidth, or the like, can be determined. The characteristic can then be compared with suitable thresholds for various multi-transceiver communication techniques, such as MIMO, multi-channel concatenation, channel diversity, and so on. Based on a comparison of the characteristic and the thresholds, a suitable multi-transceiver technique can be selected and implemented for the wireless link. Accordingly, a network can provide increased data rates and/or channel quality from a multi-transceiver technique that is most suited to prevailing conditions of the wireless network/link.Type: GrantFiled: September 13, 2018Date of Patent: November 24, 2020Assignee: AT&T MOBILITY II LLCInventors: Melvin D.

Patent number: 10701606Abstract: Intelligent radio access technology sensing and selection are applied in a dynamic traffic steering network. Network characteristics and network policies are determined. A server sends network characteristics and network policies to user equipment devices. User equipment devices can determine a radio access technology to connect to based on network policies and network characteristics. Further, it can be determined how to select user equipment devices for connection to a radio access network via a radio access technology. User equipment devices can dynamically select a radio access network for connection based on real-time or near real-time radio access network conditions. A self-organizing network can monitor and determine radio access network conditions and the radio access network conditions can be sent to user equipment devices in given cellular broadcast area.Type: GrantFiled: April 22, 2019Date of Patent: June 30, 2020Assignees: AT&T INTELLECTUAL PROPERTY I, L.P., AT&T MOBILITY II LLCInventors: Rick Tipton, Mark Austin, Zhi Cui, Alain Ohana

Patent number: 10313946Abstract: Dynamic cell resource management in wireless networking. By way of example, user terminal access parameters can be dynamically modified based on changing load conditions at one or more cells of a wireless network. For instance, resource capacity of a wireless network cell can be monitored over time to identify a potential resource overload condition. If such a condition occurs, a load management algorithm can be executed that progressively restricts or de-restricts user terminal access parameters based on changing load conditions. In particular aspects, the load management algorithm can analyze relative cell load of neighboring cells to implement coordinated load sharing. By dynamically modifying user access parameters, traffic can be directed toward or away from cells operating at low or high capacity, respectively.Type: GrantFiled: June 28, 2017Date of Patent: June 4, 2019Assignee: AT&T MOBILITY II LLCInventors: David Saska, Louis Ficarra, Kaushik Gohel, Alain Ohana
