Description

Campus mobile phone management system and method based on MEC technology

Technical Field

The invention belongs to the field of data communication networks, and particularly relates to a campus Mobile phone management system and method based on an MEC (Mobile Edge Computing) technology.

Background

Since the era of mobile internet, mobile phones as communication tools are widely popularized, the ownership rate of mobile phones in primary and middle school students is continuously increased, the problem of campus mobile phones is prominent, and no effective technical means exists for managing the campus mobile phones in the current parents and schools.

At present, schools have two types of corresponding methods for campus mobile phone management, the first type is: artificially made management regulations, such as: the method has certain obligation, often poor implementation effect, and a series of problems of teachers and students' relationship tension and the like due to the fact that the method is forbidden for students to take mobile phones, finds that the mobile phones of the students are not accepted, sets a campus mobile phone storage cabinet and customizes unified mobile phone terminals of the students.

The second type: the technical means is to manage and install a mobile phone signal shielding device in the campus. A school adopts a technical means to additionally arrange a mobile phone signal shield in a campus (mobile communication realization principle is that a mobile communication terminal and a base station are connected through radio waves in a certain frequency range, and data and sound transmission is completed in a certain baud rate and modulation mode). For the communication principle, the masker scans from the low-end frequency to the high-end frequency of the forward channel at a certain speed during operation. The scanning speed can form code disorder interference in mobile communication receiving message signals, and the mobile communication can not detect normal data sent from the base station, so that the mobile communication can not establish connection with the base station. The mobile communication is characterized by the phenomena of network searching, no signal, no service system and the like, and the effect that students cannot normally use hands in a campus is achieved.

When the signal shielding device is installed in a campus, other non-management target users in a deployment area can be seriously disturbed in communication, and meanwhile, the signal shielding device has strict limitation and regulation in use and can be generally used only in national heavy examinations and high-level conference occasions, so that most middle and primary schools cannot be installed and used.

On one hand, the signal shielding device uses the existing condition limitation and the legal restriction, meanwhile, the mode of realizing campus mobile phone management is relatively rough, and all mobile phone terminals in a campus coverage area can not normally carry out communication service through an interference blocking mode, so that non-target management user communication can not be normally carried out, and the targeted student group can not be pertinently managed by mobile phones in a campus environment.
