Abstract

The invention discloses an identification method and device for an application scenario of a mobile terminal. The mobile terminal comprises a terminal state detection module, and the identification method comprises the following steps: acquiring first time sequence state data acquired by the terminal state detection module in a preset application scenario; segmenting the first time sequence statedata by taking a preset time period as a unit, and obtaining first time window data; setting a corresponding scenario label for the first time window data according to a corresponding preset application scenario; training a deep neural network and obtaining a scenario prediction model; acquiring second time sequence state data acquired by the terminal state detection module in a to-be-predicted application scenario; segmenting the second time sequence state data by taking the preset time period as the unit, and obtaining second time window data; and inputting the second time window data into the scenario prediction model, and obtaining a scenario label of the to-be-predicted application scenario. The identification method disclosed by the invention has the advantages of simple data processing procedure, simple identification algorithm and high identification accuracy rate.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a method and device for identifying application scenarios of mobile terminals. Background technique [0002] The mining of scene information can provide important environmental information for upper-layer applications. For example, in the communication process, mobile terminal equipment needs to work in a good environment, and different environments may affect the quality of communication. For operators, scene recognition can help their network performance diagnosis. Moreover, the current mobile terminal has become an important platform for environment perception and crowd communication. Effective indoor and outdoor scene recognition methods can provide useful environmental information for terminal equipment applications, thereby effectively improving the communication quality of mobile terminals. For example, based on location services, GPS (Global Positioning System) can...
