Description: The service provider applies for the service to the background, generates an iBeaconID in the background, maps it to the service provided by the service provider, and then tells the service provider the iBeaconID. The service provider sets the iBeaconID obtained in the step to the iBeacon device, so that the iBeacon device broadcasts the iBeaconID. The user opens and shakes the surroundings within the signal range of the iBeacon device, and the App gets the iBeaconID. Through the iBeaconID obtained in the third step, the corresponding service is pulled to the background and displayed on the shaked result. The user clicks on the result, and the embedded browser will bring the user information to jump to the url that the service provider filled in when applying for the service, and enter the application page.
