Abstract

The invention discloses a signaling big data-based user travel trajectory extraction method and system, which are used for mining a user travel trajectory sequence from massive signaling data, obtaining a user position switching data sequence in an offline trajectory extraction process, detecting a user residence point by utilizing residence time and extracting a user offline trajectory. In real-time trajectory extraction, streaming computation and Geohash computation are utilized to record a Geohash grid where each user is currently located, the Geohash grid is used as a resident point, and anew resident point is generated, so that real-time trajectory data is acquired. By adopting the technical scheme provided by the invention, the real-time track and the offline track of the user can be extracted, and the flexibility is high.

Description

technical field [0001] The present invention relates to a real-time and offline dual-contrast user travel trajectory extraction method and system based on signaling big data, which is used to mine user travel trajectory sequences from massive signaling data, and belongs to the technical field of computer software technology and signaling big data mining . Background technique [0002] The development of wireless communication technology has led to an increasing usage rate of mobile devices such as mobile phones. In the 5G era, the signaling big data generated by mobile devices such as mobile phones in the process of using wireless communication services will usher in explosive growth. Signaling data contains a wealth of information such as user calls, location updates, and Internet access, especially the location information. Due to its high user coverage and good data continuity, it can be used for urban population statistics, user travel mode identification, and early warn...
