System for Actively Notifying Instant Messages and Locations in a Certain Area and Method Therefor

A system for actively notifying instant messages and locations in a certain area comprising:

• a service device function module having a processing device function module and a WiFi (Wireless Fidelity) device;
• a back-site device function module;
• a user handheld device;
• a controlling device function module judging messages and functions inputted from the back-site device function module and transmitted to the processing device function module of the service device function module, wherein the controlling device function module judges when a using contract is valid to determine when the messages and the functions of the service device function module are processed and are transmitted to the user handheld device by ways of the WiFi (Wireless Fidelity) device of the service device function module;
• wherein the back-site device function module chooses and controls the messages transmitted to the processing device function module of the service device function module, and wherein the controlling device function module judges when the using contract is valid to determine whether the messages of the processing device function module are transmitted to the user handheld device;
• wherein the service device function module judges when the user handheld device is one of a group of user handheld devices, wherein when the user handheld device is one of the group of user handheld devices, the service device function module transmits the messages to the user handheld device from the back-site device function module using the WiFi device of the service device module including positions where the group of user handheld devices are located, wherein the processing device function module has a text device module, a voice device module, an illustrated device module, an audio-visual device, a record storage module, a location information recording device module, a multi-language module, and a dynamic group management device module, wherein the WiFi device calculates the messages of the processing device function module based on messages and internal codes transmitted from the user handheld device to provide messages and locations in the certain area to the user handheld device based on a using language;
• wherein the user handheld device transmits a regional location message, a language using system code, and a group identification code of the user handheld device to the service device function module, with the user handheld device in the certain area, language messages are processed by the processing device function module of the service device function module and are transmitted to the user handheld device from the WiFi device, with the user handheld device receiving the language messages and language functions from the service device function module, with the service device function module judging a user's group type, wherein when the user's group type is identical to group members, the service device function module transmits a dynamic message of the group members to the user handheld device to provide group members' locations displayed on a map of the user handheld device, wherein the user handheld device and the group members transmit message signals to each other by the service device function module to contact and communicate with the group members.
