Selective Group Communication Parameter for Server Invitation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional group communication systems in public mobile communication networks often send invitations to all members of a pre-arranged group, which can be inefficient and unnecessary, especially when only a subset of members needs to be included in a group communication session.
Innovation Solution
Implementing a new parameter in the invitation request, such as 'no-expl', that indicates the invitation is not intended for the whole group, allowing the server to selectively invite only a specifically defined group of participants, enabling more targeted and efficient group communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the server sends invitations to all group members when a first member joins a pre-arranged group, then the group communication can be established with all members, but it causes unnecessary invitations and wastes network resources
Solution Approach 1:
The patent segments the group members into two categories: those who should receive invitations and those who should not. The server uses the indication parameter to distinguish between full group invitations and selective invitations, thereby avoiding unnecessary network resource consumption while maintaining reliable communication establishment for intended participants.
Solution Approach 2:
The patent applies local quality by making the invitation behavior different for different group members based on the indication parameter. When the parameter is present, the server selectively invites only specific members rather than all members, optimizing resource usage while ensuring reliable connection for the intended subset of participants.
2Ease of manufacture
If the server sends invitations to all group members by default, then the group communication is simple to implement, but it reduces flexibility and efficiency when only a subset of members is needed
Solution Approach 1:
The patent makes the server universal by enabling it to handle multiple invitation scenarios through a single mechanism. The server can both send invitations to all members (when the indication parameter is absent) and to selective members (when the parameter is present), thereby maintaining implementation simplicity while achieving enhanced flexibility and adaptability.
Solution Approach 2:
The patent uses parameter changes by introducing an indication parameter that modifies the server's invitation behavior. This single parameter change enables the server to adapt between different invitation modes without complicating the overall implementation, thus maintaining ease of manufacture while significantly improving versatility.
3Extent of automation
If the server triggers sending invitations to all group members automatically, then the group communication setup is automated and simple, but it increases the complexity when selective invitations are required
Solution Approach 1:
The patent extracts the complexity from the automatic invitation process by using the indication parameter to control when selective behavior occurs. The server maintains simple automatic invitation logic by default, and only becomes complex when the indication parameter triggers selective invitation mode, thereby minimizing overall system complexity while preserving automation benefits.

AI summary
In order to facilitate group communication using characteristics of a pre-arranged group but not involving all members of the pre-arranged group, a parameter indicating that the group communication is not intended to all members of the pre-arranged group is added by an inviting group member sending a request to a group server, and the group server, in response to the parameter, is configured to not to invite all members to the group communication.
