Group Service Server Message Inform Notification Mobile Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Instant Messaging & Presence Service (IMPS) systems, users cannot receive messages sent to groups unless they have actively accessed the group, leading to missed notifications, such as public announcements, from group managers.
Innovation Solution
A group service server generates message inform information to notify all users in a group of incoming messages, and a mobile terminal automatically accesses the group to receive and store these messages without requiring the user to be actively connected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users access the group continuously to receive messages, then message reception reliability is improved, but energy consumption increases and user convenience deteriorates
Solution Approach 1:
The system performs preliminary actions by having the server generate and send message notification information in advance before the user actually needs to read the message. This allows the user to be notified of message arrival without needing to continuously access the group, thus maintaining reliability while improving convenience.
Solution Approach 2:
The patent introduces message notification information as an intermediary element between the group message and the user. Instead of direct continuous access to the group, users receive notifications about message arrival, which serves as a mediator that bridges the gap between message transmission and user reception without requiring constant group access.
2Reliability
If users access the group continuously to receive messages, then message reception reliability is improved, but energy consumption increases
Solution Approach 1:
The server performs preliminary actions by generating and transmitting message notification information before the user needs to read the message. This eliminates the need for the terminal to continuously poll or maintain active connection to the group, significantly reducing energy consumption while ensuring messages are not missed.
Solution Approach 2:
Message notification information acts as an intermediary that carries essential message metadata (arrival status, sender, timestamp) without requiring the terminal to establish full group connection. This reduces the energy burden on the mobile terminal while maintaining reliable message delivery.
3Loss of information
If the system sends message notifications to all users, then information completeness is improved, but network traffic increases
Solution Approach 1:
The system extracts only the essential notification information (message arrival status, sender identity, timestamp, group identifier) from the complete group message and transmits this condensed data to users. This extraction principle ensures information completeness regarding message arrival while minimizing network traffic by sending only necessary metadata rather than full message content.
Solution Approach 2:
The message notification information is designed with local quality by containing only the specific attributes necessary for notification purposes (arrival status, sender, time, group ID) rather than transmitting complete message content. This selective information structure maintains informational completeness for notification while reducing overall data volume and network traffic.

AI summary
An apparatus and a method for automatically accessing a relevant group when determining that message inform information is transmitted from the relevant group in order to determine that the message is generated from the relevant group without accessing the relevant group are provided. The apparatus includes a group service server and a mobile terminal. The group service server generates message inform information informing of presence of a message which a user, registered in a relevant group, desires to transfer to all users registered in the relevant group when transmitting a group message. When determining reception of the message inform information informing of presence of a message which the user registered in the relevant group desires to transfer to all of the users registered in the relevant group, the mobile terminal accesses the group which has transmitted the message, receives, and stores the relevant group message.
