Patent number: 11985470Abstract: A method is for determining a wearing state of earphones. The method includes determining an onto-ears event or off-ears event experienced by the earphones on the basis of first data indicating motion of the earphones. The method further includes determining a first wearing state of the earphones on the basis of second data indicating proximity of the earphones to a user's skin. The method additionally includes determining the wearing state of the earphones on the basis of the determined onto-ears event or off-ears event and the first wearing state. This increases the accuracy of detection of the wearing state of the earphones. Based on this more accurately determined wearing state, the earphones can switch appropriately between a low power consumption mode and a normal operating mode, thereby improving the energy consumption of the earphones.Type: GrantFiled: October 27, 2020Date of Patent: May 14, 2024Assignee: Robert Bosch GmbHInventors: Chunlei Dai, Tongtong Jiao, Ji Chen, Bin Du

Patent number: 10959133Abstract: During the handover, a source base station transmits a handover request message carrying a QoS flow-based QoS parameter and/or a RB-based QoS parameter to a target base station. The target base station performs the admission control in accordance with the QoS flow-based QoS parameter or the RB-based QoS parameter, and transmits back to the source base station a handover request response message including information of a QoS flow or RB admitted successfully or unsuccessfully. The target base station performs, in accordance with the received information of the QoS flow, a convergence operation on the QoS flows which have a same QoS requirement, and generates a convergence mapping relationship from the QoS flows to the RBs and a corresponding RB configuration parameter. In addition, the target base station transmits the information of the QoS flow having been admitted to a core network.Type: GrantFiled: June 12, 2017Date of Patent: March 23, 2021Assignee: CHINA ACADEMY OF TELECOMMUNICATIONS TECHNOLOGYInventors: Ying Wang, Bin Jiao
