Patent number: 12192877Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of a proactive switch of vehicle-to-everything communication from a device-to-device connection to a connection routed by one or more network devices. In example embodiments, a first terminal device receives, from a second terminal device via a device-to-device connection, an indication of a decision to switch the device-to-device connection to a connection routed by at least one network device for communication with the second terminal device. Based on the received indication from the second terminal device, the first terminal device then determines proactive switching from the device-to-device connection to the routed connection to be performed. The first terminal device then sends a request to a first network device of the at least one network device to set up the routed connection, the request indicating a cause for the determined proactive switching.Type: GrantFiled: July 4, 2019Date of Patent: January 7, 2025Assignee: Nokia Technologies OyInventors: Lianghai Ji, Jakob Lindbjerg Buthler, Vinh Van Phan, Ling Yu, Hajo Bakker, Rudraksh Shrivastava, Bernhard Wegmann, Xiang Xu
