Embodiment

With reference to the accompanying drawings the present invention is more comprehensively described, exemplary embodiment of the present invention wherein is described.

For realizing above-mentioned purpose, the dynamic information acquisition methods of a kind of position-based and TPEG has been proposed.

Below in conjunction with the drawings, execution mode of the present invention is described.

The key point of acquisition methods of dynamic information that realizes a kind of position-based and TPEG is following:

Traffic information collection:

Obtain to automation the information source that outside needs push, for example various transport information source such as TMC Traffic Message Channel.

Terminal positioning:

Perhaps position through autonomous GPS location, terminal through mobile network's locating platform.

Information filtering:

In a large amount of transport information that collects, classify and inquire about through logic parameters such as positions, so that user terminal is extracted and be pushed to fast that the position is relevant transport information.

The information coding:

Rate dynamic according to data push is taked suitable coded format, like XML form or binary form, takes XML can also transmit preceding compression to reduce data amount transmitted.
