Title: Network switching method and electronic device
Inventor: YANG RUI
IPC: H04W36/00
Filed: 2020-11-11
Abstract: A network handover method and an electronic device relate to the field of terminal technologies, to help reduce a possibility that frame freezing or a network disconnection occurs when a user accesses a network by using the electronic device. The method specifically includes: When the electronic device camps on a first network accessed by using a first communications module, the electronic device sequentially obtains network information of a first sampling point and network information of a second sampling point for the first network in a process in which the electronic device moves along a first route at an n th  time, and predicts whether the first network becomes abnormal after first duration elapses. If the electronic device predicts that the first network becomes abnormal, before the first network becomes abnormal, the electronic device camps on a second network. In this technical solution, the electronic device may be handed over to the second network in advance when predicting that the first network becomes abnormal. This reduces a possibility that frame freezing or a network disconnection occurs when a user accesses a network by using the electronic device, thereby improving user experience.

Abstract: Techniques are disclosed for the protection and accuracy of system time used in systems, such as automotive systems, from attacks. In some embodiments, a cumulative trustworthiness score is determined for available time sources, other than a real time clock, by adding together trustworthiness scores associated with the available time sources after a system time is initialized to time of the real time clock during booting. The cumulative trustworthiness score is then used to determine an appropriate technique for updating the system time based on time from one of the available time sources, depending on whether the cumulative trustworthiness score is greater than a maximum threshold, between a minimum threshold and the maximum threshold, or less than the minimum threshold.
