Problems solved by technology

Therefore, the synchronization range cannot well meet the synchronization requirements of vehicle-mounted user terminals outside the network coverage. Similarly, similar problems also exist in other synchronization scenarios, such as the synchronization scenario in the Internet of Things, which will not be described here.

Abstract

The invention discloses an information synchronization method and device and a mobile terminal. The information synchronization method comprises the steps: a first mobile terminal detects surrounding synchronization signals, and determines a to-be-synchronized synchronization signal according to a preset rule; if the determined synchronization signal is sent by a first synchronization source, the synchronization priority of the first mobile terminal is determined as a first priority, wherein the first synchronization source comprises a satellite or a base station; if the determined synchronization signal is sent by the second mobile terminal, the synchronization priority of the first mobile terminal is determined as a third priority, wherein the third priority is lower than the second priority of the second mobile terminal; and synchronization is performed by using the determined synchronization signal, and the determined priority is added to the synchronization signal, and then the synchronization signal is sent to other mobile terminals except the first mobile terminal. According to the embodiment of the invention, the synchronization precision of the mobile terminals beyond the network coverage range of the base station can be improved.

Description

technical field [0001] The present invention relates to the communication field / terminal field, in particular to an information synchronization method, device and terminal equipment. Background technique [0002] In a communication network, some information needs to be aligned among base stations, user terminals and network nodes, such as time alignment. Therefore, information synchronization between base stations, user terminals and network nodes is performed through synchronization signals. [0003] Here, the LTE-V2X synchronization scenario is taken as an example to introduce information synchronization, see figure 1 , figure 1 It is a scene diagram of the synchronization mechanism based on the long term evolution technology-vehicle-to-vehicle communication technology (LTE-V2X, Long term evolution-Vehicle to Everything). The synchronization sources of information are: base station and Global Navigation Satellite System (GNSS, Global Navigation Satellite System). The id...
