Abstract

The invention discloses a method and a system independent of a map in a navigation system. The system comprises a push-to-talk service application module, an SD protocol conversion module, a 2.4G wireless module, a small terminal, a remote dialing device and a backstage. The push-to-talk service application module is communicated with the SD protocol conversion module through a secure digital input and output card (SDIO) interface. The SD protocol conversion module is communicated with the 2.4 G wireless module through a serial port. The small terminal internally comprises a microprogrammed control unit (MCU) with a computer processing function, a radio frequency module used for being connected with the 2.4 G wireless module and a Bluetooth module for being connected with the remote dialing device. The remote dialing device exchanges data with the backstage through a wireless communication network. According to the method and the system independent of the map in the navigation system, operation is simplified, the same push-to-talk programme can be used by different map softwares, a respective push-to-talk programme is not needed to be designed in each map software.

Description

technical field [0001] The invention relates to the field of car navigation, in particular to a push-to-talk service method and system not dependent on maps in a navigation system. Background technique [0002] Push-to-talk is a soft dial and hard dial product that provides manual services with dialing in car navigation. The traditional push-to-talk (software) is designed in the map software, and the corresponding push-to-talk logo is also designed together with the map software. This has great limitations. [0003] The traditional push-to-talk is designed in the map interface. When the user clicks the push-to-talk logo on the map interface, the map software will call the corresponding DLL function to send a message to the central control program WINCE, and the WINCE central control program receives the message Then send the corresponding command to control the dialing module to dial the background. Therefore, the prerequisite for using PTT is that the map software is ope...
