Embodiment

[0031] The method for obtaining traffic information through a mobile terminal proposed by the preferred embodiment of the present invention, the specific method flow is as follows figure 1 shown, including:

[0032] Step 1. The traffic information extraction server on the network side randomly selects one or more mobile terminals in the network to which it belongs as the selected mobile terminal;

[0033] Step 2, the network side extracts the location information of the selected mobile terminal according to the predetermined measurement;

[0034] The preset rules are specifically: if the selected mobile terminal is positioning, then extract the location information of the mobile terminal; if the selected mobile terminal is not positioning, then extract the signal between the mobile terminal and the base station obtained by the mobile terminal Extend the value, and query the preset positioning database to locate the mobile terminal;

[0035] Step 3, the traffic information ex...

Abstract

The invention discloses a method for acquiring traffic information through mobile terminals, belonging to the technical field of communication. The method comprises the following steps: using a network side traffic information extraction server to extract one or more than one mobile terminal in the network as the selected mobile terminal according to preset rules; continuously extracting positioninformation of the selected mobile terminal, and tracking the position of the selected mobile terminal; and determining traffic information of the area of the terminal by using the network side traffic information extraction server according to the motion conditions of the tracked mobile terminal. In such a way, the invention can effectively utilize the 3G network and the mobile terminals in the 3G network to extract the traffic information. Meanwhile, the invention does not need to add a new hardware module to the mobile terminal so as to lower the initial input for traffic information acquisition, and can be used for acquiring accurate traffic information by means of precise positioning and sufficient terminal samples.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for acquiring traffic information through a mobile terminal. Background technique [0002] There are three main types of traffic information extraction commonly used at present. One is to install cameras on each road section and directly shoot to obtain the traffic information of the road section. The second is to install a position detection module (such as GPS) on the vehicle to detect the vehicle speed when the vehicle is running, judge the traffic conditions of the road section, and communicate the traffic conditions of the road sections where each vehicle is located to other vehicles. The third is to rely on sensors such as radar, magnetic induction loop detection device, rubber pipe, etc., and use multiple such sensors to derive traffic information parameters such as vehicle speed, vehicle length, traffic flow, and vehicle density. The above three traffic i...
