Abstract

A method for realizing vehicle-mounted voice intercom by using a mobile network aims at overcoming the defects that the call quality cannot be ensured or the call cost is higher in traditional voice intercom in the prior art. The invention provides the method for realizing the vehicle-mounted voice intercom by using the mobile network. Hardware comprises a set of vehicle-mounted navigator and voice intercom server; the vehicle-mounted navigator and the voice intercom server form a voice intercom system through the mobile network; and a voice intercom program is installed on the vehicle-mounted navigator. The method mainly comprises five steps, namely transmitting an intercom request, recording the speaking content of a user, transmitting the record through the mobile network, transferring data by the voice intercom server and receiving and playing the record by other users. According to the method disclosed by the invention, the transmitting quality of voice is ensured and the cost of intercom between users is reduced; and the method is suitable for environments for carrying out vehicle-mounted voice intercom.

Description

technical field [0001] The invention relates to the application field of vehicle-mounted navigation and Internet of Vehicles, in particular to a method for realizing vehicle-mounted voice intercom by using a mobile network. Background technique [0002] Traditional voice intercom methods mainly include walkie-talkie calls and mobile phone calls. Walkie-talkie calls do not require a network, and voice transmission is realized directly by transmitting and receiving signals between walkie-talkie devices. There is no charge for the call process, but when the voice is transmitted in real time, the call quality is easily affected by distance and obstacles. Mobile phone calls are transmitted in real time through the voice channel of the mobile network. Generally, the billing is based on the duration of the call, and the cost of the call is relatively high. To sum up, although intercom calls do not charge call charges, the call quality cannot be guaranteed, while mobile phone calls...
