Online group interaction system and method based on RDS (Remote Data Services)

Abstract

The invention discloses an online group interaction system and method based on RDS (Remote Data Services). The method comprises the following steps that: a client side transmits a request to a server side through an SMS (Short Message Service) protocol or an HTTP (Hyper Text Transfer Protocol); the server carries out the logical processing and data persistence; the server periodically transmits the latest globe control information to a radio station; the radio station receives the globe control information and modulates the RDS broadcast; the client side separates the audio and digital information through RDS demodulation and stores valid messages to the local after receiving an FM (Frequency Modulation) modulating signal, the client side automatically updates show views according to the globe control information in the RDS messages. According to the technical scheme provided by the invention, due to the fact that the RDS carries out the data broadcast only by means of the rich frequency range of the existing modulation frequency broadcast, the site building input can be reduced greatly, the client side receives RDS broadcast information without information charges. The system and the method can be a more convenient information acquiring way for the vast rural areas with incomplete internet coverage and low-income users and the middle-low income community in the cities.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a system and method for online group interaction based on RDS communication. Background technique [0002] At present, there are abundant group interactive applications based on Web technology on the Internet. This kind of application uses the Internet as the transmission medium, the service provider server and the user's computer as the processing terminal, and the client software as the information interaction window. First of all, its communication characteristics are: the client and the server use the interactive method of Request-Response (request-response) to complete the communication through the HTTP protocol. During the communication process, the client is responsible for sending user requests, and the client request processing module of the server completes operations such as request reception, parameter extraction, and response return. Secondly,...

AI Technical Summary

Problems solved by technology

According to the analysis of communication and application characteristics, the advantage of this group interactive application is that the application scene can be shared among multiple terminals, and the user can complete the interaction with other users through the request and response between the server; the disadvantage is: for each For a client request, the server must establish and maintain a TCP (Transmission Control Protocol, Transmission Control Protocol) connection

Therefore, the demand for a large number of user visits will increase the cost of building a Web site. At the same time, the communication mode between the server and the client is two-way, and the operator will charge the client for communication fees during the uplink and downlink processes.
