Abstract

The disclosed method for traffic information data broadcast comprises: setting traffic region as well as the covered wireless honeycomb subzone; setting corresponding information data; allocating one broadcast / multicast business stream with business stream label opposite to said traffic area; broadcasting the business stream on said subzone. This invention brings benefit to user and can improve city traffic capacity.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a broadcasting method and a broadcasting system for broadcasting traffic information data, a receiving method and a mobile station for receiving broadcasted traffic information data. Background technique [0002] How to obtain accurate traffic information data conveniently and in time is very important for urban traffic. The driver can adjust the driving route in time according to the road conditions provided by the traffic information data, avoid the roads with heavy traffic, and choose relatively idle roads, thereby improving the utilization rate of idle roads, reducing the traffic load on busy roads, and improving urban traffic. Transport capacity. [0003] At present, the transmission of traffic information data is mainly through wireless FM broadcasting. The radio station broadcasts the collected and edited traffic information data through wireless FM broadcasting. Use...
