Publication number: 20220345940Abstract: The disclosed technology is directed towards load balancing in an adaptive and automated way for wireless mobility networks to improve the overall harmonic-average UE throughput within each controlled group of cells (e.g., different frequency carriers serving a sector of a base station). A load balancer (e.g., analytics component) obtains various device traffic data including throughput data for cells of a group. Pairs of cells in a group (sharing a site and face) can be selected based on satisfying various criteria, with estimated throughput gain achieved by changing the handoff rates between the cell pairs. The technology iteratively repeats the overall process, driving a system to an optimal equilibrium.Type: ApplicationFiled: July 8, 2022Publication date: October 27, 2022Inventors: Gopalakrishnan Meempat, Huahui Wang, Slawomir Stawiarski, Senthil Raj Dhandapani, Huijing Yang, Dongho Kim, Kemal Kara, Ravi Raina, Weihua Ye, Hyun Ok Lee

Patent number: 11206589Abstract: A device can receive, from a network node device, call trace event data relating to characteristics of a wireless communication session between the network node device and a user equipment. The device can sequence and combine the call trace event data for a period of the wireless communication session. The device can analyze the call trace event data to determine a category of network communication traffic transmitted via a communication channel between the network node device and the user equipment. In response to a determination that the network communication traffic comprises streaming video packets, the device can facilitate directing of network resources to be allocated to support the wireless communication session.Type: GrantFiled: July 30, 2020Date of Patent: December 21, 2021Assignee: AT&T Intellectual Property I, L.P.Inventors: Jie Chen, Wenjie Zhao, Ke Zhang, Huijing Yang, Huahui Wang

Patent number: 10995408Abstract: A method of electroless nickel plating on surface of silicon carbide powder with a uniform and stable coating. In this method, ultrasonic assist is introduced in the pre-treatment and during plating process, and the powder particles in the liquid are dispersed and deagglomerated by the mechanical action and cavitation of the ultrasonic waves, thereby achieving a uniform dispersion of the powder in the dispersant. Furthermore, a reducing agent is slowly added during plating so as to give a more uniform and stable deposition of the coating onto the surface of the powder particles, and thus a silicon carbide core-nickel shell structure with an excellent powder dispersibility and a uniform and stable coating is produced.Type: GrantFiled: November 30, 2018Date of Patent: May 4, 2021Assignee: Tangshan Normal UniversityInventor: Huijing Yang
