Messaging service provision method for open chat rooms
A recently granted patent (Publication Number: US11778429B2) describes a messaging service providing method that allows users to participate in open chat rooms through a messaging application. The method involves transmitting a link information issuance request to a messaging server, which generates link information for the open chat room. This link information is then shared with users who can access the open chat room regardless of whether they are friends with the host terminal user in the messaging application.
The method allows for chat conversations between the user of the host terminal and users of guest terminals who participate in the open chat room through the shared link information. The link information issuance request includes profile user information associated with the host terminal user and requirement information associated with the guest terminal user. The profile information can be either a default profile or an open profile set by the host terminal user, and the requirement information includes entry requirements set by the guest terminal user.
The patent also describes the ability to generate multiple open chat rooms if the open chat room is a one-to-one type and multiple guest terminals select the link information. Each open chat room is then dedicated to a guest terminal for chatting with the host terminal user.
The messaging service method allows for the open chat room to be distinguishable from a general chat room and can be shared through various posting spaces such as webpages or online spaces within the messaging application or other service applications.
The host terminal is configured to display the number of open chat rooms corresponding to the link information or the number of new messages received in the open chat room. When the host terminal user leaves the open chat room, it is deleted from the messaging server after a predetermined period.
The patent also covers methods performed by guest terminals and the messaging server, which involve receiving and participating in open chat rooms generated by the messaging server through the link information.
Overall, this patent describes a messaging service method that allows for the creation and participation in open chat rooms through shared link information, providing users with a distinct and accessible chat experience.
