Publication number: 20240132070Abstract: The present disclosure relates to a method of generating a target operational speed band (53; 63; 67) for a host vehicle (1) travelling along a route. A first time-dependent obstacle (15-n, 18-n) is identified at a first location on the route. The first time-dependent obstacle (15-n, 18-n) is identified as hindering progress of the host vehicle (1) during a first time period (I1). The first time-dependent obstacle (15-n, 18-n) is defined in a two-dimensional speed against distance map (50, 60). A first speed trajectory (51, 52; 61; 65, 66) is determined from a first point to a second point within the two-dimensional speed against distance map (50, 60). The second point represents the first location on the route and the determined first speed trajectory (51, 52; 61; 65, 66) represents the host vehicle (1) arriving at the first location at a first arrival time.Type: ApplicationFiled: December 28, 2023Publication date: April 25, 2024Inventors: Tommi JOKELA, Alex PLIANOS

Patent number: 11930416Abstract: A method includes determining, by a source base station, based on at least one of a measurement report received from a terminal device and a mobility trajectory of the terminal device, a prepared cell list that includes a set of cells where the terminal device is capable of handover. The method includes sending at least one required context for the handover to the set of cells in the prepared cell list. The method also includes receiving acknowledgement from the set of cells. The method further includes sending a handover complete message, which contains the prepared cell list, to the terminal device. The prepared cell list provides a capability for the terminal device to make a number of handovers when the terminal device is within a coverage area of the set of cells.Type: GrantFiled: September 17, 2019Date of Patent: March 12, 2024Assignee: Nokia Solutions and Networks OYInventors: Mikko Säily, Tommi Jokela, Sofonias Hailu
