Communication method and apparatus of Android center control large screen and mobile terminal

Abstract

The invention discloses a communication method and apparatus of an Android center control large screen and a mobile terminal. The method comprises the following steps: when a Service module of the Android center control large screen is successfully started, dynamically registering a broadcast used for detecting a state change of a wifi hotspot in the Android center control large screen in the Service module; after a connection request signal of the mobile terminal is received, establishing a Socket connection with the mobile terminal via the wifi hotspot; and communicating with the mobile terminal by adopting a specified message protocol. By adoption of the communication method and apparatus disclosed by the invention, the mobile terminal such as a mobile phone and the like can directly communicate with the Android center control large screen of a vehicle based on the wifi hotspot of the Android center control large screen via the Socket directly without the transfer connection of a cloud server, so that the communication is more timely, is independent from an independent router and network cloud and is independent from networks such as 4G, so that the communication method and apparatus can be widely used in vehicle network industry.

Description

technical field [0001] The invention relates to the field of vehicle networking communication, in particular to a communication method and device for an Android central control large screen and a mobile terminal. Background technique [0002] The interconnection and communication between mobile phones and cars has become an essential feature of the current Internet of Vehicles. The common communication method between mobile phone and car is to connect the mobile phone to the cloud server through 4G and other networks, and then transfer to the car's Android central control large screen. The success of this interconnection communication method is based on whether the network signal is smooth or not. However, in some occasions where the network signal is not good or even there is no network signal, such as underground garages, mountainous areas, etc., the speed of establishing a connection between the mobile phone and the car is slow, the effect is poor or even the connection c...

Problems solved by technology

The common communication method between mobile phone and car is to connect the mobile phone to the cloud server through 4G and other networks, and then transfer to the car's Android central control large screen. The success of this interconnection communication method is based on whether the network signal is smooth or not. However, in some occasions where the network signal is not good or even there is no network signal, such as underground garages, mountainous areas, etc., the speed of establishing a connection between the mobile phone and the car is slow, the effect is poor or even the connection cannot be established

Moreover, cloud servers are required for transfer, which affects the timeliness of communication and is not conducive to the development of Internet of Vehicles
