Patent number: 11774263Abstract: The described technology is generally directed towards creation of shared overlay maps to support automated, real-time, cross-platform sharing of map information among groups of digital navigational map users, including but not limited to unmanned ground vehicles (UGVs). A central map authority (or other collaborative/federated organizational entity) can receive map overlay information from a mobile subscriber device, such as a UGV. The central map authority can promulgate the map overlay information to a group of multiple mobile subscriber devices according to the techniques described herein. Individual mobile subscriber devices can use received map overlay information, along with their individual digital navigational maps (DNMs) and navigation systems, to plan their individual routes.Type: GrantFiled: March 11, 2020Date of Patent: October 3, 2023Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Deva-Datta Sharma, John Oetting

Publication number: 20230128442Abstract: The described technology is generally directed towards proactive content placement for low latency mobile access. Digital content requested by a mobile device can be sent to network nodes proactively, so that the network nodes have the digital content before it is requested by the mobile device. Mobile device travel predictions can be made to predict future locations of the mobile device. The future locations can be used to determine network nodes for proactive digital content delivery. The digital content for delivery to a network node can also be predicted based on current digital content in use at the mobile device and estimated arrival times of the mobile device into service areas of next network nodes.Type: ApplicationFiled: December 15, 2022Publication date: April 27, 2023Inventors: Deva-Datta Sharma, John Oetting, Vishwa M.

Patent number: 11425652Abstract: Deployment of Internet-of-things devices can comprise sensors deployed in remote and hard to reach areas and locations. Due to lack of access to reliable power, these sensors cannot always be connected to a network and also have limited computation power. Consequently, a mechanism can be established to periodically access these sensors and collect data from them. The mechanism can utilize a mobile radio unit device to serve as data collectors. The mobile radio unit device can make use of an adaptive beam scanning to perform sensory data collection via the beam scanning operation. Additionally, the platform can also comprise a radio access network intelligent controller to manage the data collecting radio units by providing specific instructions and data collection methodologies.Type: GrantFiled: November 24, 2020Date of Patent: August 23, 2022Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Mostafa Tofighbakhsh, Shraboni Jana, Bogdan Ungureanu, Deva-Datta Sharma, Rittwik Jana

Patent number: 11297554Abstract: An intelligent determination of a set of candidate handover-beams for a radio access network (RAN) can be facilitated by a RAN intelligent controller (RIC). The RIC can obtain data associated with user equipment devices and their current state, historical patterns, and a current state of serving network node devices and neighboring network node devices. Based on the obtained data, a handover procedure can be optimized by the user equipment by estimating the signal quality from a source cell and neighboring cells. Additionally, the user equipment can send measurement reports to the network to identify and quantify the quality of reference signals transmitted by the network node devices.Type: GrantFiled: March 28, 2019Date of Patent: April 5, 2022Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Mostafa Tofighbakhsh, Shraboni Jana, Deva-Datta Sharma, Rittwik Jana, Bogdan Ungureanu
