Method for selective communication by using receiver filtering and providing unenrolled-user message sending in multi-user communication for after-school teachers

摘要

The present invention relates to a system for arbitrarily selecting and communicating conversation recipients through filtering in multiple communications such as conversations with parents, taking into account the characteristics of a lecturer, and a service method for supporting message transmission to users who have not yet been registered. Basically, the sender (instructor) creates a 1: N chat room, and the message sent through the chat room is provided to show the recipient 1: 1 conversation. In this chat room, a group of conversation recipients are arbitrarily selected and filtered, and a message is transmitted and confirmed only to the recipients selected in the filtered result. These messages are displayed in a 1: 1 conversation on the recipient side. Also, in consideration of members joining later, unregistered users arbitrarily create a member table to receive a message and accumulate a conversation on the server. It compares the registered information with the registered information through the unique information (telephone number, etc.) at the time of subscription, and displays the message by matching the subscription information with the existing information. And provides a selective communication management service and an unregistered message transmission service in a multi-recipient environment to the sender (lecturer), thereby providing an efficient, fast and accurate communication service.
