Abstract

Disclosed in the embodiments of the invention are a vehicle-mounted emergency call method and device, used for solving the problems of an emergency rescue centre being unable to acquire an MSD due tothe current service state of a wireless network being invalid and the low probability of the emergency rescue centre successfully acquiring an MSD due to a poor wireless network signal. The specific solution comprises: acquiring an MSD; and, when determining that the wireless communication function of a vehicle-mounted eCall apparatus has a fault, sending the MSD to an auxiliary device by means ofa near distance communication module, such that the auxiliary device sends the MSD to a server. The embodiments of the application are used in the process of a vehicle-mounted eCall apparatus issuingan emergency call.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201710125018.8 and the title of the invention "A method and device for in-vehicle emergency calling" submitted to the China Patent Office on March 3, 2017, the entire contents of which are incorporated by reference in this application in the file. technical field [0002] The embodiments of the present application relate to the communication field, and in particular, to a method and device for in-vehicle emergency calling. Background technique [0003] In the process of road transportation, automobiles often have traffic accidents. At this time, if the rescuers can learn the accident information in time and carry out rescue, then the parties involved in the accident can be rescued in time, thereby reducing property losses and casualties. [0004] In the prior art, in order to allow rescuers to obtain accident information in a timely manner, a vehicle-mounted emergency ca...
