Abstract

The invention discloses a bus station moving flow prediction method and system based on GW and SVR and a storage medium. The SVR is used for predicting the movement flow of the long-distance bus station, and the optimal parameters of the SVR are optimized through the grey wolf optimization algorithm, so that the tedious manual parameter selection process of the SVR is omitted, and the movement flow of the long-distance bus station is accurately predicted. The invention has the advantages that (1) the SVR algorithm is used for predicting the mobile network flow of the long-distance bus station,so that the mobile flow of the bus station is accurately predicted, and the network security and the experience of the bus station with large pedestrian flow in holidays and festivals are guaranteed;and (2) the advanced meta-heuristic optimization algorithm is used for optimizing the optimal parameters of the SVR, the GW optimization algorithm selected by the invention not only inherits the advantages of the meta-heuristic optimization algorithm, but also has the advantages of strong search capability and difficulty in falling into local optimum, and the complex manual parameter selection process of the SVR algorithm is omitted.

Description

technical field [0001] The present invention relates to the field of large-scene mobile Internet traffic prediction, in particular to a GW and SVR-based mobile traffic prediction method, system and storage medium for bus stations. Background technique [0002] With the development of mobile Internet technology and the comprehensive popularization of smart phones, mobile Internet data traffic has shown explosive growth. Telecom network operators have changed from the traditional "call fee operation" model to the "data flow operation" model, and the "unlimited" packages launched have further promoted the growth of traffic. The rapid increase in mobile traffic and user scale has brought great challenges to the pressure on the current network, and also seriously affected user experience. Accurately predicting the total traffic of the mobile network and doing security work in advance can effectively ensure the safe and stable operation of the network. Due to the significant pos...
