1. Product Introduction

The mobile phone control system establishes an integrated group management framework, enabling signal suppression, network blocking, and mass SMS alerts. It restricts device interactions with external networks while periodically blocking smartphone operations—including photography, video recording, and audio recording—through targeted pop-up notifications. This comprehensive approach effectively prevents the spread of related incidents across digital platforms.

2.1 Pop-up SMS

In the group event, the coverage area of the vehicle-mounted equipment makes the controlled mobile phone periodically (<1s) receive screen-occupying messages, making the mobile phone unable to operate, so that it cannot take photos or video; it can compile the content of the messages by itself to drive away the troublemakers.

After the pop-up message is triggered on the target phone, it will be directly displayed on the screen. If you do not click to close or exit the phone, you cannot operate it. If the phone is in the recording state, the recording behavior will be directly interrupted. The pop-up message can be sent periodically to effectively restrict the operation of the target phone.

2.2 Communication interruption

By shutting down the target phone and connecting it to the 2G network of the Strong Control device, the target will be unable to surf the Internet and do business normally, effectively cutting off the communication channels with the outside world.

3． application scenarios

The strong control system is applied in the following scenarios to reduce the social impact of the corresponding events:

Mass incidents: In large-scale events such as rallies and demonstrations, it is necessary to temporarily restrict the functions of participants' mobile phones in order to prevent the rapid spread of event information on the Internet and cause greater social impact.

Emergency: In emergency situations such as terrorist attacks, it is necessary to control mobile phones in the affected areas to prevent the spread of rumors and panic.

The channels of event information dissemination can be summarized as the following three points:

(1) mobile phone network

During the event, if the mobile phone network and call of participants or onlookers are unimpeded, it is convenient for external contact and data transmission, and the on-site data can be easily transmitted to the outside.

(2) Phone video

Mobile phone photography, video recording, audio recording and other behaviors are convenient, and small and hidden, even if there is a recording behavior is difficult to find.

(3) The curiosity of onlookers

People are often curious about novel, rare or sudden events, and onlookers hope to satisfy their own and others' curiosity by spreading the video.

(4) The information security awareness of onlookers

Onlookers are unable to make a reasonable judgment on the impact caused by the dissemination of information about vicious events, so it is necessary to take relevant measures to give effective warning and intervention, improve the information security awareness of relevant personnel, and reduce the social impact caused by the event.

To comprehensively analyze the characteristics of events and the way of event transmission, intervention should be given from three perspectives: mobile network layer, mobile behavior and people's security awareness.
