Embodiment Construction

[0027] The technical solutions provided by the various embodiments of the present invention can be applied in the field of traffic information, especially in various traffic-only applications, for example.

[0028] figure 1 It is a schematic flowchart of a method for acquiring mobile information provided by an embodiment of the present invention. The method includes:

[0029] Step 101, monitor the quality of traffic samples.

[0030] In this embodiment, the traffic samples are various samples used for traffic information applications, including movement information, or may also include other position-related information. Specifically, for example, two consecutive location pairs of the same mobile terminal. The movement information is mainly location information, and may also include other information such as speed information.

[0031] In this embodiment, the quality of traffic samples can be evaluated by one or more factors. For example, the quality of traffic samples ca...

Abstract

The invention relates to a method for acquiring mobile information. The method comprises the steps: monitoring the quality of a traffic sample, wherein the traffic sample is a sample used for traffic information application; when the quality of the traffic sample is lower than a threshold value, activating and / or adjusting the grouped data business of a mobile terminal; acquiring the mobility management data of the mobile terminal; and extracting mobile information from the mobility management data, wherein the mobile information comprises position information. The invention also relates to a device for acquiring mobile information. Through the technical scheme provided by the invention, enough traffic samples with high quality can be acquired through activating or adjusting the grouped data business, and thus, various traffic applications can be met.

Description

technical field [0001] The invention relates to the field of traffic information, in particular to a technology for acquiring mobile information. Background technique [0002] With the popularization of cellular terminals, various traffic vehicles carrying cellular terminals spread all over the street network of the whole city. Cellular terminals may include cellular handsets, smartphones, and other wireless devices connected to cellular networks. Correspondingly, more and more attention has been paid to a new theory of using cellular terminals as traffic detectors, which extracts the movement information of these cellular terminals from their mobility management data, and generates traffic information accordingly. The technology applying this theory is also called Cellular Floating Vehicle data (CFVD) technology. Since these mobility management data already exist in the existing cellular network and are easy to obtain, no additional infrastructure is required, and no modi...
