Road condition information-based digital broadcasting realization method and device

Abstract

The invention is applicable to the technical field of communication and provides a road condition information-based digital broadcasting realization method and a road condition information-based digital broadcasting realization device. The method comprises the following steps: when a communication client starts a traffic road condition function, accessing a broadcasting channel to receive road condition information broadcast by TD multimedia and a multicast service TD-MBMS service platform; when the road condition information broadcast by the TD-MBMS service platform is received completely, informing the communication client of receiving the road condition information; and sending the road condition information received from the TD-MBMS service platform to the communication client. In theinvention, a point-to-point service for sending data from a data source to multiple users is realized, network resource sharing is realized effectively, and networks can provide identical high-rate multimedia and data services for a large number of users in the same time period; in addition, through the broadcasting of the road condition information, the communication terminal user can get the traffic road condition information at a current position in time during driving.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method and a device for realizing digital broadcasting based on road condition information. Background technique [0002] At present, the data services deployed on the live network are all based on the point-to-point distribution model, and there are a large number of homogeneous distribution service requirements: mobile newspapers, music players, mobile TVs, etc. The market demand for multimedia services is increasing, and the same service data is transmitted at the same time, and the resources of the access network and the core network are wasted by point-to-point distribution. The resource consumption is proportional to the user scale. With the expansion of the user scale, the resource consumption can It is foreseeable that, in addition, using this point-to-point distribution method, the efficiency of communication is very low. Contents of the invention ...
